          <dc:description xml:lang="en">Summarization: Mainstream Traffic Flow Control (MTFC), enabled via variable
            speed limits, is a control concept for real-time freeway traffic management. The benefits of MTFC for
            efficient freeway traffic flow have been demonstrated recently using an optimal control approach and a
            feedback control approach. In this paper, both control approaches are reviewed and applied to a freeway
            network in a simulation environment. The validated network model used reflects an actual freeway (a
            ring-road), fed with actual (measured) demands. The optimal and feedback control results are discussed,
            compared and demonstrated to improve significantly the system performance. In particular, the feedback
            control scheme is deemed suitable for immediate practical application as it takes into account operational
            requirements and constraints, while its results are shown to be satisfactory. In addition, the control
            system performance was not very sensitive to variations of the parameters of the feedback controller. This
            result indicates that the burden associated with fine tuning of the controller may be reduced in the field.

          <dc:description xml:lang="en">Summarization: This paper describes a novel approach for defining optimal
            strategies in motorway traffic flow control, considering that a portion of vehicles are equipped with
            vehicle automation and communication systems. An optimisation problem, formulated as a Quadratic Programming
            (QP) problem, is developed with the purpose of minimising traffic congestion. The proposed problem is based
            on a first-order macroscopic traffic flow model able to capture the lane changing and the capacity drop
            phenomena. An application example demonstrates the achievable improvements in terms of the Total Time Spent
            if the vehicles travelling on the motorway are influenced by the control actions computed as a solution of
            the optimisation problem.

          <dc:description xml:lang="en">Summarization: The Adaptive Cruise Control (ACC) system, is one of the emerging
            vehicle technologies that has already been deployed in the market. Although it was designed mainly to
            enhance driver comfort and passengers’ safety, it also affects the dynamics of traffic flow. For this
            reason, a strong research interest in the field of modelling and simulation of ACC-equipped vehicles has
            been increasingly observed in the last years. In this work, previous modelling efforts reported in the
            literature are reviewed, and some critical aspects to be considered when designing or simulating such
            systems are discussed. Moreover, the integration of ACC-equipped vehicle simulation in the commercial
            traffic simulator Aimsun is described; this is subsequently used to run simulations for different
            penetration rates of ACC-equipped vehicles, different desired time-gap settings and different networks, to
            assess their impact on traffic flow characteristics.

            (VSLs) is a freeway traffic control method that aims to maximize throughput by regulating the mainstream
            flow upstream from a bottleneck. Previous studies in a macroscopic simulator have shown optimal and feedback
            MTFC potential to improve traffic conditions. In this paper, local feedback MTFC is applied in microscopic
            simulation for an on-ramp merge bottleneck. Traffic behavior reveals important aspects that had not been
            previously captured in macroscopic simulation. Mainly, the more realistic VSL application at specific points
            instead of along an entire freeway section produces a slower traffic response to speed limit changes. In
            addition, the nonlinear capacity flow/speed limit relation observed in the microscopic model is more
            pronounced than what was observed at the macroscopic level. After appropriate modifications in the control
            law, significant improvements in traffic conditions are obtained.

            stability and global exponential stability, which can be applied to nonlinear, large-scale, uncertain

          <dc:description xml:lang="en">Summarization: A widespread use of vehicle automation and communication systems
            (VACS) is expected in the next years. This may lead to improvements in traffic management because of the
            augmented possibilities of using VACS both as sensors and as actuators. To achieve this, appropriate
            studies, developing potential control strategies to exploit the VACS availability, are essential. This paper
            describes a model predictive control framework that can be used for the integrated and coordinated control
            of a motorway system, considering that vehicles are equipped with specific VACS. Microscopic simulation
            testing demonstrates the effectiveness and the computational feasibility of the proposed approach.

          <dc:description xml:lang="en">Summarization: Emerging vehicle automation and communication systems (VACS) may
            contribute to the mitigation of motorway traffic congestion on the basis of appropriate traffic control
            strategies. Based on appropriate VACS-based actuators, future traffic control may incorporate vehicle speed
            control and lane-assignment or lane-changing recommendations. To this end, an appropriate traffic flow model
            is needed, both for control strategy design and as a no-control base case for comparative evaluation
            studies. In this context, this paper presents a novel first-order multi-lane macroscopic traffic flow model
            for motorways which is mainly intended for use within a related optimal control problem formulation. The
            starting point is close to the well-known cell-transmission model (CTM), which is modified and extended to
            consider additional aspects of the traffic dynamics, such as lane changing and the capacity drop. The model
            has been derived with a view to combine realistic traffic flow description with a simple (piecewise linear)
            mathematical form, which can be exploited for efficient optimal control problem formulations. Although the
            model has been primarily derived for use in future traffic conditions including VACS, it may also be used
            for conventional traffic flow representation. In fact, the accuracy of the proposed modelling approach is
            demonstrated through calibration and validation procedures using conventional real data from an urban
            motorway located in Melbourne, Australia.

          <dc:description xml:lang="en">Summarization: Vehicle merging on highways has always been an important aspect,
            which directly affects the capacity of the highway. Under critical traffic conditions, the merging of main
            road traffic and on-ramp traffic is known to trigger speed breakdown and congestion. Additionally, merging
            is one of the most stressful tasks for the driver, since it requires a synchronized set of observations and
            actions. Consequently, drivers often perform merging maneuvers with low efficiency. Emerging vehicle
            technologies, such as cooperative adaptive cruise control and/or merging-assistance systems, are expected to
            enable the so-called “cooperative merging”. The purpose of this work is to propose a cooperative merging
            system and evaluate its performance and its impact on highway capacity. The modeling and simulation of the
            proposed methodology is performed within the framework of a microscopic traffic simulator. The proposed
            model allows for the vehicle-to-infrastructure (V2I) and vehicle-to-vehicle (V2V) communication, which
            enables the effective handling of the available gaps between vehicles. Different cases are examined through
            simulations, in order to assess the impact of the system on traffic flow, under various traffic conditions.
            Useful conclusions are derived from the simulation results, which can form the basis for more complex
            merging algorithms and/or strategies that adapt to traffic conditions.

          <dc:description xml:lang="en">Summarization: The well-known feedback ramp metering algorithm ALINEA can be
            applied for local ramp metering or included as a key component in a coordinated ramp metering system. ALINEA
            uses real-time occupancy measurements from the ramp flow merging area that may be at most few hundred meters
            downstream of the metered on-ramp nose. In many practical cases, however, bottlenecks with smaller capacity
            than the merging area may exist further downstream for various reasons, which suggests using measurements
            from those further downstream bottlenecks. Recent theoretical and simulation studies indicate that ALINEA
            may lead to a poorly damped closed-loop behavior in this case, but PI-ALINEA, a suitable
            Proportional-Integral (PI) extension of ALINEA, can lead to satisfactory control performance. This paper
            addresses the same local ramp-metering problem in the presence of downstream bottlenecks, with a particular
            focus on the general capacity of PI-ALINEA with three distinct types of bottleneck that may often be
            encountered in practice, i.e. (1) an uphill case; (2) a lane-drop case; (3) an un-controlled on-ramp case.
            Extensive simulation studies are conducted using a macroscopic traffic flow model to demonstrate that the
            performance of ALINEA indeed deteriorates in each of these bottleneck cases,
            while significant improvement is obtained using PI-ALINEA in all cases. Moreover, with its control
            parameters appropriately tuned beforehand, PI-ALINEA is found to be universally applicable, with little
            fine-tuning required for field applications.

          <dc:description xml:lang="en">Summarization: We address the problem of learning robot control by model-free
            reinforcement learning (RL). We adopt the probabilistic model of Vlassis and Toussaint (2009) for model-free
            RL, and we propose a Monte Carlo EM algorithm (MCEM) for control learning that searches directly in the
            space of controller parameters using information obtained from randomly generated robot trajectories. MCEM
            is related to, and generalizes, the PoWER algorithm of Kober and Peters (2009). In the finite-horizon case
            MCEM reduces precisely to PoWER, but MCEM can also handle the discounted infinite-horizon case. An
            interesting result is that the infinite-horizon case can be viewed as a ‘randomized’ version of the
            finite-horizon case, in the sense that the length of each sampled trajectory is a random draw from an
            appropriately constructed geometric distribution. We provide some preliminary experiments demonstrating the
            effects of fixed (PoWER) vs randomized (MCEM) horizon length in two simulated and one real robot control
            tasks.

          <dc:description xml:lang="en">Summarization: Model simulations of soil organic carbon turnover in agricultural
            fields have inherent uncertainties due to input data, initial conditions, and model parameters. The RothC
            model was used in a Monte-Carlo based framework to assess the uniqueness of solution in carbon sequestration
            simulations. The model was applied to crop production to set aside conversions in Iowa (sandy clay-loam
            soil, humid-continental climate) and Greece (clay-loam soil,
            Mediterranean). The model was initialized and calibrated with particulate organic carbon data obtained by
            physical fractionation. The calibrated values for the Iowa grassland were 5.05 t C ha-1, 0.34 y-1, and 0.27
            y-1 24 for plant litter input and decomposition rate constants for resistant plant material (RPM) and humus,
            respectively, while for the Greek shrubland these were 3.79
            t C ha-1, 0.21 y-1, and 0.0041 y-126 , correspondingly. The sensitivity analysis revealed that for both
            sites, the total plant litter input and the RPM rate constant showed the highest sensitivity. The Iowa soil
            was projected to sequester 17.5 t C ha-1 and the Greek soil 54 tC ha- 28 1 29 over 100 years and the
            projected uncertainty was 65.6% and 70.8%, respectively. We
            propose this methodology to assess the factors affecting carbon sequestration in agricultural soils and
            quantify the uncertainties.

          <dc:description xml:lang="en">Summarization: This study investigated the effect of municipal solid waste (MSW)
            compost (0, 50, and 100 t/ha) on N cycling and the microorganisms involved in it, in a clay-loam soil. After
            a release of nitrates (NO3--N) in the first 6 days after compost incorporation, soil NO3--N content remained
            constant in all the treatments by day 62 suggesting immobilization of N. Then, soil NO3--N content
            increased, especially in the highest compost dose implying that the immobilization effect has been relieved,
            at least to some extent. amoA gene copies of ammonia oxidizing archaea (AOA) and ammonia oxidizing bacteria
            (AOB) followed strictly the pattern of soil NO3--N content throughout the study providing evidence that both
            groups were involved in ammonia oxidation and changes in their population can be used as ‘indicator’ for
            predicting changes in soil nitrification status. Moreover, the strong correlation between AOA 12 and AOB
            amoA copies (R2: 0.94) and the high slope (13) of the curve suggest that AOA had probably a more important
            role on ammonia oxidation under conditions of low ammonia availability. Denitrifying genes (nirS, nirK,
            nosZ) also followed the general pattern of soil NO3–-N and they were strongly correlated with both groups of
            ammonia oxidizers, and particularly archaea, suggesting strong interrelationships among them. Losses of N
            through denitrification, as they were estimated from total nitrogen decrease, were inversely related to soil
            NO3--N content. Similar to ammonia oxidizers, denitrifying gene copies did not differ among compost
            treatments an effect that could be probably explained by the low availability of organic-C of the MSW
            compost and hence the competition with aerobic heterotrophs.

          <dc:description xml:lang="en">Summarization: Soil ecosystem functions have significantly deteriorated due to
            agricultural intensification with dramatic consequences on carbon loss, loss of soil biodiversity, erosion,
            compaction as well as unsustainable use of water and mineral resources. Sustainable agricultural practices
            are necessary if we are to face the challenge of food security while preserving the integrity of soil and
            aquatic ecosystems. Conservation agriculture which is comprised of zero or minimum tillage, carbon
            amendments and crop rotations holds great promise in delivering higher yields, using water and soil
            resources in a sustainable manner and increasing soil biodiversity. This paper presents a synthesis of
            current knowledge on soil ecosystem processes and modeling with a focus on carbon and nitrogen dynamics and
            their link to soil structure, and proposes a conceptual framework for model parameterization capable of
            predicting critical soil functions and potential shifts.
            We reviewed the dynamics of carbon, nitrogen and soil structure with an emphasis in elucidating predominant
            state variables and the interaction with plants and food web dynamics. Existing models that simulate the
            dynamics of organic matter and structure in soils at various scales were evaluated for their ability to
            simulate the functions of soil ecosystem. Current modeling approaches treat carbon, nitrogen and soil
            structure for the most part separately without incorporating feedback mechanisms. The synergistic and
            antagonistic processes between bacteria and plants and fungi and plants are partially understood and more
            importantly the community lacks the knowledge to predict if and when these processes fail and any related
            potential ecosystem shift. A conceptual modeling framework is proposed, developed along the following three
            axes: incorporate emerging ecosystem state variables, account for the ecology of life in soils, and model
            processes from first principles. A synthesis of the carbon and nitrogen cycles is suggested in which the
            dynamics of the two cycles are interlinked. State variables in soil ecosystem models that link carbon and
            nitrogen dynamics with soil structure and the biological community are recommended. Plant feedback
            mechanisms with the physical, biochemical and biotic soil components and the symbiotic relationship between
            bacteria, fungi, and plants should be modeled using principles from the ecological succession theory that
            would relate the taxonomic structure with function and nutrient fluxes. A conceptual model of soil structure
            and soil stability is suggested that links the soil organic matter sub-model to an aggregation sub-model and
            a dynamic soil structure sub-model. The development of new generation soil ecosystem models is a necessary
            step to better quantify soil functions, assess possible soil tipping points, and develop methods to restore
            soil functions.

          <dc:description xml:lang="en">A three-dimensional, bench-scale model aquifer was constructed
            to study the dissolution of a TCE pool. The aquifer
            consisted of medium-sized sand packing conveying steady, unidirectional
            flow. A key aspect of the experimental design was a
            mechanism by which a TCE pool of an ideal (circular) geometry
            was placed and maintained in direct contact with the
            bottom of the porous medium. The aqueous plume emanating
            from this pool was monitored at several downgradient sampling
            stations and analyzed using the analytical solution derived by Chrysikopoulos [1995]. All transport
            parameters required
            by this solution, with the exception of the average mass
            transfer coefficient (k*) for the pool, were estimated independently.
            Of special note are the dispersion parameters, which
            were estimated independently by fitting the results of a bromide
            tracer test with a newly derived analytical solution describing
            the transport of a conservative tracer in a homogeneous
            aquifer of finite thickness.

          <dc:description xml:lang="en">Summarization: A unique three-dimensional bench-scale model aquifer is designed
            and
            constructed to carry out dense nonaqueous phase liquid (DNAPL) pool dissolution
            experiments. The model aquifer consists of a rectangular glass tank with internal
            dimensions 150.0 cm length, 21.6 cm width, and 40.0 cm height. The formation of a welldefined
            circular pool with a perfectly flat pool-water interface is obtained by a bottom
            plate with a precise cutout to contain the DNAPL. The aquifer is packed with a wellcharacterized
            relatively uniform sand. A conservative tracer is employed for the
            determination of the longitudinal and transverse aquifer dispersivities. The dissolution
            studies are conducted using a circular trichloroethylene (TCE) pool. The sorption
            characteristics of TCE onto the aquifer sand are independently determined from a flowthrough
            column experiment. Steady state dissolved TCE concentrations at specific
            downstream locations within the aquifer are collected under three different interstitial
            velocities. An appropriate overall mass transfer coefficient is determined from each data
            set. The data collected in this study are useful for the validation of numerical and
            analytical DNAPL pool dissolution models.

          <dc:description xml:lang="el">Περίληψη: This paper is concerned with the interconnected operation of WECS with
            the utility grid.Specifically ,it addresses problems of stability , protection and power flow optimization
            from the WECS to the power lines.
            The approach followed contains both a theoritical and a experimental component.A variable-speed
            constant-frequency wind electric system utilizing a synchronous generator and line-commutated inverter
            provides experimental verification of computer simulation studies for the dynamic and steady-state
            performance of the interconnected system.
            Simulation results indicate that the transient bahavior of the wind electric-power grid system is
            satisfactory with appropriate devices providing adequate protection to both the wind generator and the
            utility grid from a variety of fault conditions.
            A maximum power tracking mechanism has been designed for the continuous matching of the wind-electric
            generator to the grid impedance characteristics.As a result,maximum electric power is transferred from the
            wind machine to the power lines.Computer simulation studies of this type of operation indicate the
            substantial improvement in power transfer that is achieved.
            The proposed scheme tends to minimize equipment and maintenance costs while maximizing the energy transfer
            capabilities of the wind-electric conversion system and maintaining a high degree of reliability in overall
            system performance.

          <dc:description xml:lang="en">Summarization: The paper introduces a new technique for the indirect measurement
            of the systolic and diastolic blood pressure in humans. The technique is based upon a statistically
            consistent relationship between the amplitude of the pulsatile pressure waveform at the systolic and
            diastolic points and the amplitude of pulse signals detected when the artery is fully occluded. An adaptive
            measurement philosophy has been implemented in the design of an electronic sphygmomanometer which, in
            addition to a pressure transducer, contains suitable electronic instrumentation for processing and
            displaying the electronic signals. Verification of overall system accuracy is accomplished with direct
            comparison with manual auscultatory measurements. Clinical testing of a prototype indicates a satisfactory
            performance; measurement errors are maintained well within proposed standards for automated
            sphygmomanometers.

          <dc:description xml:lang="en">Summarization: This paper is introducing a new methodology for the dynamic
            integration of dispersed storage and generation devices into the electric utility distribution network
            operations. The dispersed source is viewed as an active device contributing towards the regulation of real
            and reactive power flows while improving the stability of the power system. Conceptual means are developed
            for an effective DSG-utility grid interface. Computer models of appropriate interconnection and control
            equipment are used in simulation studies to test the effectiveness of control strategies and optimize design
            parameters. Simulation results indicate that load frequency control and voltage regulation may be
            effectively accomplished with dispersed generators within a fraction of the time required for conventional
            regulating units. Appropriate modulation and conditioning of the DSG-output power can assist in damping out
            undesirable power oscillations. Implementation of the proposed policies may result in reduced load following
            requirements for conventional power generating units, increase the value and acceptability of new energy
            technologies, and improve power quality and stability of the interconnected system.

          <dc:description xml:lang="en">Summarization: An analog-digital photovoltaic (PV) array simulator is
            considered. The analog section is designed on the basis of an equivalent solar cell model while the digital
            section is constructed realizing the mathematical representation of the array. Fast time responses achieved
            by the analog section make this part suitable for the study of transient phenomena associated with the
            interconnected operation of PVs and the utility grid. Its digital counterpart is more appropriate for
            long-term experimental investigations due to its inherent accuracy and reliability. The combined hybrid
            simulator offers a versatile and flexible piece of apparatus capable of simulating the performance of any PV
            array under a variety of operating conditions. The device can be constructed with low-cost components in a
            compact arrangement offering transportability and ease of operation. Experimental results derived from a
            laboratory constructed prototype match closely the theoretically computed characteristics.

          <dc:description xml:lang="en">Summarization: This paper describes the implementation on a microprocessor of a
            new method for the indirect measurement and recording of the systolic and diastolic blood pressure in
            humans. The technique is based on a statistical analysis of the cardiac pulse pressure signal. Polynomial
            relations are derived between the amplitude of the pulsatile pressure waveforms at the systolic and
            diastolic points and the amplitude of pulse signals detected when the artery is fully occluded. With the
            dual objective of automating the measurement procedure and minimizing errors, an electronic analog-digital
            sphygmomanometer that contains suitable electronic instrumentation was developed. The functions of
            processing the pressure signal, automating the measurement, and recording the results are performed and
            controlled by a microprocessor. A laboratory prototype embodying this approach was constructed and its
            performance and reliability were verified using a series of clinical tests. The test results indicate that
            the device is accurate within acceptable bounds for automated blood pressure instruments.

          <dc:description xml:lang="en">Summarization: This paper describes an analytical methodology for the optimised
            design of stand-alone photovoltaic (PV) systems installed at locations where the solar radiation is
            considerably shortened by obstacles, i.e. at the bottom of a gorge. A method for the computation of the real
            available solar energy incident on the PV panel is proposed, based on easily conducted measurements. The
            optimum tilt of the PV array, under such conditions, is obtained and a dimensioning procedure provides the
            optimal size of the PV-array/storage. The resulting system is tested by a verification routine. A case
            study, employing the complete algorithm proposed, is illustrated.

          <dc:description xml:lang="en">Summarization: The inspection planning in electric power industry is used to
            assess the safety and reliability of system components and to increase the ability of failure situation
            identification before it actually occurs. It reflects the implications of the available information on the
            operational and maintenance history of the system. The output is a ranked list of components, with the most
            critical ones at the top, which indicates the selection of the components to be inspected.

            In this paper, we demonstrate the use of a fuzzy relational database model for manipulating the data
            required for the criticality component ranking in thermal power systems inspection planning, incorporating
            criteria concerning aspects of safety and reliability, economy, variable operational conditions and
            environmental impacts. Often, qualitative thresholds and linguistic terms are used for the component
            criticality analysis. Fuzzy linguistic terms for criteria definitions along with fuzzy inference mechanisms
            allow the exploitation of the operators' expertise.

            The proposed database model ensures the representation and handling of the aforementioned fuzzy information
            and additionally offers to the user the functionality for specifying the precision degree by which the
            conditions involved in a query are satisfied.

            In order to illustrate the behavior of the model, a case study is given using real inspection data.

          <dc:description xml:lang="en">Summarization: The development of faster, simpler, inexpensive and more
            environmentally friendly sample-preparation techniques is an important issue in chemical analysis. Recent
            research trends involve miniaturisation of the traditional liquid-liquid extraction (LLE) principle by
            greatly reducing the acceptor-to-donor phase ratio. One of the emerging techniques in this area is
            liquid-phase microextraction (LPME), where a hollow fibre impregnated with an organic solvent is used to
            accommodate or protect microvolumes of acceptor solution. This novel methodology proved to be an extremely
            simple, low-cost and virtually solvent-free sample-preparation technique, which provided a high degree of
            selectivity and enrichment by additionally eliminating the possibility of carry-over between runs. This
            article presents the different modes and hollow-fibre configurations of LPME, followed by an up-to-date
            summary of its applications. The most important parameters and practical considerations for method
            optimisation are also discussed. The article concludes with a comparison of this novel method with
            solid-phase microextraction (SPME) and single-drop microextraction (SDME).

          <dc:description xml:lang="en">Summarization: The continuous quest for novel sample preparation procedures has
            led to the development of new methods, whose main advantages are their speed and negligible volume of
            solvents used. The most recent trends include solvent microextraction, a miniaturisation of the traditional
            liquid–liquid extraction method, where the solvent to aqueous ratio is greatly reduced. Single-drop
            microextraction is a methodology that evolved from this approach. It is a simple, inexpensive, fast,
            effective and virtually solvent-free sample pretreatment technique. This article provides a detailed and
            updated discussion of the developments, modes and applications of single-drop microextraction, followed by a
            brief description of the theoretical background of the method. Finally, the most important parameters as
            well as some practical considerations for method optimisation and development are summarised.

          <dc:description xml:lang="en">Summarization: A new method for the determination of trace levels of cationic
            ions by anion selective membrane collection is presented. Anion selective membranes containing a few
            micrograms of different complexing reagents in polyvinyl chloride (PVC) matrix were produced in quartz
            reflectors. The membranes were immersed in water solutions with low concentrations of cationic metals, Cu,
            Co, Ni, Zn, and of anionic ligands (CN−, etc.). After the equilibration time the reflectors were left to dry
            and they were analyzed by Total X-Ray Fluorescence (TXRF). Many experimental parameters (pH effect, size of
            the membrane, volume sample) were examined. The minimum detection limits were estimated to be 1 ng/ml for
            all metallic cations even in seawater. The method needs less working labor than other enrichment procedures,
            the cations are collected directly on the TXRF reflector surface and very small chemical reagent consumption
            is needed.

          <dc:description xml:lang="en">Summarization: This paper describes a computer simulation model which has been
            developed to study the effects of integrating wind energy conversion systems (WECS) into autonomous power
            systems. The quality of the interconnected system performance is specified in terms of operational
            constraints. Load-flow and power-system-stability studies were preformed in order to evaluate the
            penetration impact of a 4·5 MW wind farm on the local grid fo Sitia-Crete. The results show that the above
            wind energy penetration level will not cause any problem to the existing electric power grid.

            system, when the incident solar radiation is considerably obstructed, is presented in this article. An
            optimal dimensioning method is proposed based on a new procedure for the calculation of the actual solar
            radiation on the array surface, for installations located near obstacles. The optimum tilt of the PV array
            is also computed and the resulting optimal PV-array/battery-storage system is evaluated by an appropriate
            routine. The results of the application of the complete algorithm for a real case study inside a gorge are
            illustrated.

            insecticides from water samples coupling single-drop microextraction with gas chromatography–mass

            volume and salt concentration were controlled and optimised. Overall, extraction was achieved by suspending
            a 1.5 μl toluene drop to the tip of a microsyringe immersed in a 5 ml donor aqueous solution containing 2.5%
            NaCl (w/v) and stirred at 800 rpm. The developed protocol was found to yield a linear calibration curve in
            the concentration range from 0.5 to 100 μg l−1 for all target analytes. Under selected ion monitoring mode,
            the limits of detection were found to be in the range between 0.010 and 0.073 μg l−1.

            bis[3-(2-pyridyl)pyrazol-1-yl]phosphinate (as its triethylammonium salt). This compound has two potentially
            chelating N,N′-bidentate arms linked by an apical PO 2 - group. Reaction with AgNO 3 , Tl(O 2 CMe), Pb(NO 3
            ) 2 or Ba(NO 3 ) 2 in dry MeCN followed by recrystallisation afforded crystals of the complexes [AgL]·2H 2
            O, [TlL]·MeOH, [PbL 2 ]·H 2 O and [(BaL 2 ) 3 ]·6MeCN·2H 2 O respectively, all of which have been
            crystallographically characterised. The compound [AgL]·2H 2 O contains infinite helical chains (AgL) ∞ in
            which each ligand donates one N,N′-bidentate arm to each of two metals and each metal ion is
            four-co-ordinated by two arms from different ligands. The strands are held together in the crystal by a
            complex network of hydrogen bonds involving lattice water molecules and also by aromatic π-stacking
            interactions. The compound [TlL]·MeOH is likewise a one-dimensional helical polymer of TlL units, with each
            ligand bridging two metals and each Tl ion in a ‘2 + 3’ co-ordination geometry with two short bonds to
            ligands (&lt;2.71 Å) and three longer, weak bonds (&gt;2.87 Å): there is an obvious gap in the co-ordination
            sphere due to a stereochemically active lone pair. A combination of interstrand aromatic π-stacking
            interactions and hydrogen-bonding interactions involving the lattice MeOH molecule is present.

            investigated. Experiments were conducted
            with a horn-type sonicator operating at 80 kHz frequency and a nominal applied power of 135 W, while
            solid-phase microextraction
            coupled with gas chromatography–electron capture detector (SPME/GC–ECD) was employed to monitor triclosan
            degradation.
            The latter followed pseudo-first order kinetics with the rate constant being (min1): 0.2284 for seawater
            &gt; 0.1051 for 3.5% NaCl in deionised

            to
            check for the formation of chlorinated and other toxic by-products; at the conditions in question, the
            presence of such compounds
            was not confirmed.

            near-coplanar arrangement of the pyridyl and phenyl rings.

          <dc:description xml:lang="en">Summarization: Lanthanide complexes of two polydentate N-donor ligands
            containing a mixture of pyridyl and pyrazolyl donors have been prepared.
            Dihydrobis[3-(2-pyridyl)pyrazolyl]borate (L 1 ) - is a tetradentate ligand with two bidentate chelating
            pyridyl/pyrazolyl arms linked by an apical BH 2 group; 2,6-bis(1H-pyrazol-3-yl)pyridine (L 2 ) is a
            terdentate chelating ligand reminiscent of terpyridine. Reaction of L 1 with lanthanide salts gave complexes
            of the type [M(L 1 ) 2 X] n+ ; the crystal structures of [Eu(L 1 ) 2 (dmf)][ClO 4 ]· 2.5CH 2 Cl 2 , [Tb(L 1
            ) 2 (NO 3 )]·2CH 2 Cl 2 and [Tb(L 1 ) 2 (H 2 O)][L 1 ]· H 2 O·0.5CH 2 Cl 2 were determined and all contain
            two tetradentate ligands L 1 and an ancillary ligand X [dimethylformamide (dmf), nitrate or water] whose
            nature depends on the reaction/recrystallisation conditions to complete the co-ordination sphere.
            Luminescence studies of [Tb(L 1 ) 2 (NO 3 )] in water or D 2 O and MeOH or CD 3 OD showed that in methanol
            the solvation number q is ≈1.8, consistent with displacement of nitrate by the solvent; however in water q ≈
            4.5, indicating additional displacement of some of the N-donor heterocyclic rings of L 1 by co-ordinating
            water molecules. Reaction of L 2 with lanthanide salts afforded [M(L 2 ) 3 ] 3+ , all isolated as their
            hexafluorophosphate salts. The crystal structures of three of these (M = Eu, Gd or Ho) showed that they are
            isostructural and isomorphous, with tricapped trigonal-prismatic nine-co-ordinate geometries similar to that
            of [M(terpy) 3 ] 3+ (terpy = 2,2′:6′,2″- terpyridine).

            chemistry.1–4 They are of particular interest not just for their appealing structures but also because
            of the processes of molecular recognition and self- assembly that are required for their
            formation. Their formation requires (i) ligands which contain several discrete metal-ion binding
            domains, and (ii) metal ions with specific preferences for particular coordination geometries that
            match the ligand binding sites.

            has been prepared and its structure determined by X-ray crystallography. The ruthenium is co-ordinated on
            one side by the nido-7,8-C 2 B 9 H 11 fragment in a pentahapto manner, and on the other by the two CO
            molecules and the alkyne [Ru–C av. =2.305, C–C=1.228(3) Å. Treatment of 3c with PEt 3 and Ph 2 PCH 2 PPh 2
            in CH 2 Cl 2 affords the ylid complexes [Ru{C(Me)C(Ph)PEt 3 }(CO) 2 (η 5 -7,8-C 2 B 9 H 11 )] (4b) and

            was established by an X-ray diffraction study which revealed that the PEt 3 molecule was attached to the
            carbon atom of the CPh group. In contrast, reactions between 3c and the donor molecules AsPh 3 , SbPh 3 and
            Ph 2 P(S)CH 2 P(S)Ph 2 resulted in displacement of the alkyne and formation of the complexes [Ru(CO) 2 (L)(η

            the Ru(CO) 2 (η 5 -7,8-C 2 B 9 H 11 ) fragment yielded the diruthenium complex [Ru 2 (μ-Ph 2 PCH 2 PPh 2

            B 9 H 11 ) groups by the ligand Ph 2 PCH 2 PPh 2 , was determined by X-ray crystallography. NMR data for the
            new complexes are reported.

          <dc:description xml:lang="en">Summarization: Hexachlorobenzene (HCB), a model volatile compound, was exposed
            to UV irradiation (16 W, 254 nm) after being sorbed in an internally cooled or low temperature solid-phase
            microextraction (LT-SPME) fibre. Photolysis took place directly on the polydimethylsiloxane coating of the
            LT-SPME fibre, yielding an “in situ” generation of photoproducts. Maintaining the temperature of the cold
            fibre at 0 °C eliminated, for the first time, problems of analyte losses due to volatilisation, inherent to
            the conventional room temperature photo-SPME studies. During the present studies, nearly complete
            photoremoval of HCB could be achieved within 20 min of irradiation. Photoreduction through
            photodechlorination was shown to be the main decay pathway in which lesser chlorinated congeners were
            sequentially formed as intermediates. Accordingly, initial generation of pentachlorobenzene was followed in
            order from 1,2,3,5-tetrachlorobenzene, 1,2,4,5-tetrachlorobenzene and 1,3,5-trichlorobenzene.

          <dc:description xml:lang="en">Summarization: This work investigates the photolysis of 2,4-dinitrotoluene
            (2,4-DNT) in the presence of different dissolved species. Initial experiments revealed that the direct
            photolysis of 2,4-DNT in deionized water solutions under sunlight and artificial light followed a
            pseudo-first order kinetic. Humic acids (HA) appeared to act as sensitizers in the aqueous photolysis of
            2,4-DNT and the calculated half life was found to be approximately 2 h, which is faster than the half life
            calculated in the case of deionized water (∼4 h). The presence of salt (NaCl) in the deionized water
            solutions was found to have a more pronounced sensitizing effect upon the photolysis of 2,4-DNT, yielding
            half lives of the order of 1 h. Investigations on seawater and groundwater spiked with 2,4-DNT, revealed
            that photolysis is enhanced in the order seawater &gt; groundwater∼deionized water.

            2-(2-hydroxyphenyl)-1,10-phenanthroline (HL) and its Fe(III) complex [FeL2][PF6] (1) have been determined.
            In HL, an intramolecular OH … N hydrogen bond between the phenolic OH and the adjacent nitrogen atom of the
            phenanthroline fragment constrains these two donor atoms to be cisoid, with the proton ‘chelated’. The
            molecules of HL are associated into pairs in the crystal via a face-to-face aromatic π-stacking interaction.
            Complex 1 has a conventional distorted octahedral structure; sections of the aromatic ligands overlap
            between adjacent molecules to form an interleaved stack. It is high-spin down to 83 K, and its EPR spectrum
            (frozen glass at 77 K) is entirely typical of a rhombically distorted high-spin FeIII site.

            into the photochemical degradation of 2,2′,4,4′,6-pentabromodiphenyl ether (BDE-100) in ice solid samples

            technique for monitoring trace amounts of the hydrophobic pollutant and its photoproducts. The results
            showed that ice photolysis kinetics for BDE-100 is similar to the one observed in the aqueous counterpart.
            The eight photoproducts identified consisted of brominated diphenyl ethers with lower bromine content and
            polybrominated dibenzofurans, suggesting two important photodegradation pathways for BDE-100 in ice solid

          <dc:description xml:lang="en">Summarization: The main objective of this work was to assess and compare the
            levels, patterns, and sources of contamination of 16 polycyclic aromatic hydrocarbons (PAHs) between
            Portugal, Spain, and Greece (in the island of Crete). A total of 9 sampling sites were chosen (4 in urban
            and 5 in non-urban areas) in each country and pine needles from the Pinus pinea L. species were collected.
            Although the mean total PAH levels was similar in the three countries (279 ± 236 ng g−1 for Portugal, 294 ±
            258 ng g−1 for Spain, 301 ± 253 ng g−1 for Greece, all dry weight) and, in general, 3-ring and 4-ring PAHs
            were predominant (being phenanthrene consistently the most abundant), there were some visible differences in
            the aromatic ring patterns and possible sources between the three regions. Source apportionment was done
            using PAH ratios (Phen/Ant and Flt/Pyr crossplots) and reflected mixed petrogenic and pyrogenic sources.
            Furthermore, Principal Component Analysis (PCA) clearly separated the urban and the non-urban sites and all
            three countries, which reinforces that the sources of contaminations vary in each case and the suitability
            of pine needles for trans-boundary biomonitoring of PAHs.

          <dc:description xml:lang="en">Summarization: For the first time, Vacuum Assisted Headspace Solid Phase
            Microextraction (Vac-HSSPME) is used for the recovery of polycyclic aromatic hydrocarbons (PAHs) from solid
            matrices. The procedure was investigated both theoretically and experimentally. According to the theory,
            reducing the total pressure increases the vapor flux of chemicals at the soil surface, and hence improves
            HSSPME extraction kinetics. Vac-HSSPME sampling could be further enhanced by adding water as a modifier and
            creating a slurry mixture. For these soil-water mixtures, reduced pressure conditions may increase the
            volatilization rates of compounds with a low KH present in the aqueous phase of the slurry mixture and
            result in a faster HSSPME extraction process. Nevertheless, analyte desorption from soil to water may become
            a rate-limiting step when significant depletion of the aqueous analyte concentration takes place during
            Vac-HSSPME. Sand samples spiked with PAHs were used as simple solid matrices and the effect of different
            experimental parameters was investigated (extraction temperature, modifiers and extraction time). Vac-HSSPME
            sampling of dry spiked sand samples provided the first experimental evidence of the positive combined effect
            of reduced pressure and temperature on HSSPME. Although adding 2 mL of water as a modifier improved
            Vac-HSSPME, humidity decreased the amount of naphthalene extracted at equilibrium as well as impaired
            extraction of all analytes at elevated sampling temperatures. Within short HSSPME sampling times and under
            mild sampling temperatures, Vac-HSSPME yielded linear calibration curves in the range of 1–400 ng g−1 and,
            with the exception of fluorene, regression coefficients were found higher than 0.99. The limits of detection
            for spiked sand samples ranged from 0.003 to 0.233 ng g−1 and repeatability from 4.3 to 10 %. Finally, the
            amount of PAHs extracted from spiked soil samples was smaller compared to spiked sand samples, confirming
            that soil could bind target analytes more strongly and thus decrease the readily available fraction of
            target analytes.

          <dc:description xml:lang="en">Summarization: The diagrammatic approach is an alternative to standard
            analytical methods for solving stochastic differential equations governing groundwater flow with spatially
            variable hydraulic conductivity. This approach uses diagrams instead of abstract symbols to visualize
            complex multifold integrals that appear in the perturbative expansion of the stochastic flow solution and
            reduces the original flow problem to a closed set of equations for the mean and the covariance functions.
            Diagrammatic analysis provides an improved formulation of the flow problem over conventional first-order
            series approximations, which are based on assumptions such as constant mean hydraulic gradient, infinite
            flow domain, and neglect of cross correlation terms. This formulation includes simple schemes, like
            finite-order diagrammatic perturbations that account for mean gradient trends and boundary condition
            effects, as well as more advanced schemes, like diagrammatic porous media description operators which
            contain infinite-order correlations. In other words, diagrammatic analysis covers not only the cases where
            low-order diagrams lead to good approximations of flow, but also those situations where low-order
            perturbation is insufficient and a more sophisticated analysis is needed. Diagrams lead to a nonlocal
            equation for the mean hydraulic gradient in terms of which necessary conditions are formulated for the
            existence of an effective hydraulic conductivity. Three-dimensional flow in an isotropic bounded domain with
            Dirichlet boundary conditions is considered, and an integral equation for the mean hydraulic head is derived
            by means of diagrams. This formulation provides an explicit expression for the boundary effects within the
            three-dimensional flow domain. In addition to these theoretical results, the numerical performance of the
            diagrammatic approach is tested, and useful insight is obtained by means of one-dimensional flow examples
            where the exact stochastic solutions are available.

          <dc:description xml:lang="en">Summarization: The fractional Gaussian noise (fGn) and fractional Brownian
            motion (fBm) random field models have many applications in the environmental sciences. An issue of practical
            interest is the permissible range and the relations between different fractal exponents used to characterize
            these processes. Here we derive the bounds of the covariance exponent for fGn and the Hurst exponent for fBm
            based on the permissibility theorem by Bochner. We exploit the theoretical constraints on the spectral
            density to construct explicit two-point (covariance and structure) functions that are band-limited fractals
            with smooth cutoffs. Such functions are useful for modeling a gradual cutoff of power-law correlations. We
            also point out certain peculiarities of the relations between fractal exponents imposed by the mathematical
            bounds. Reliable estimation of the correlation and Hurst exponents typically requires measurements over a
            large range of scales (more than 3 orders of magnitude). For isotropic fractals and partially isotropic
            self-affine processes the dimensionality curse is partially lifted by estimating the exponent from
            measurements along fixed directions. We derive relations between the fractal exponents and the
            one-dimensional spectral density exponents, and we illustrate the relations using measurements of paper
            roughness.

          <dc:description xml:lang="en">Summarization: The spatial structure of fluctuations in spatially inhomogeneous
            processes can be modeled in terms of Gibbs random fields. A local low energy estimator (LLEE) is proposed
            for the interpolation (prediction) of such processes at points where observations are not available. The
            LLEE approximates the spatial dependence of the data and the unknown values at the estimation points by
            low-lying excitations of a suitable energy functional. It is shown that the LLEE is a linear, unbiased,
            non-exact estimator. In addition, an expression for the uncertainty (standard deviation) of the estimate is
            derived

          <dc:description xml:lang="en">Summarization: The aim of this paper is to present and evaluate control
            strategies for adjustment and preservation of air quality, thermal and visual comfort for buildings’
            occupants while, simultaneously, energy consumption reduction is achieved. Fuzzy PID, fuzzy PD and adaptive
            fuzzy PD control methods are applied. The inputs to any controller are: the PMV index affecting thermal
            comfort, the CO2 concentration affecting indoor air quality and the illuminance level affecting visual
            comfort. The adaptive fuzzy PD controller adapts the inputs and outputs scaling factors and is based on a
            second order reference model. More specifically, the scaling factors are modified according to a sigmoid
            type function, in such a way that the measured variable to be as closer as possible to the reference model.
            The adaptive fuzzy PD controller is compared to a non-adaptive fuzzy PD and to an ON–OFF one. The comparison
            criteria are the energy required and the controlled variables response. Both, energy consumption and
            variables responses are improved if the adaptive fuzzy PD type controller is used. The buildings’ response
            to the control signals has been simulated using MATLAB/SIMULINK.

            viable solution, ensuring both indoor comfort for the occupants and reduction of energy consumption. The aim
            of this paper is to present the architecture of a distributed building energy management system that can be
            installed in new as well as in existing buildings, which are more energy inefficient. The system integrates
            a smart card unit, acting as a user machine interface, sensors, actuators, interfaces, a PLC controller that
            incorporates the fuzzy control algorithm, local operating network (LON) modules and devices and an optional
            PC which monitors the performance of the system. The distributed control architecture is based on the
            properties of the LON. The complete system is installed and tested in the Laboratory of Electronics of the
            Technical University of Crete.

            networks, real-time recurrent neural networks and their innovative variations are proposed, compared and
            discussed in this paper. The performance of each presented structure is evaluated by means of an extensive
            simulation study, using actual hourly load data from the power system of the island of Crete, in Greece. The
            forecasting error statistical results, corresponding to the minimum and maximum load time-series, indicate
            that the load forecasting models proposed here provide significantly more accurate forecasts, compared to
            conventional autoregressive and BP forecasting models. Finally, a parallel processing approach for 24 h
            ahead forecasting is proposed and applied. According to this procedure, the requested load for each specific
            hour is forecasted, not only using the load time-series for this specific hour from the previous days, but
            also using the forecasted load data of the closer previous time steps for the same day. Thus, acceptable
            accuracy load predictions are obtained without the need of weather data that increase the system complexity,
            storage requirement and cost.

          <dc:description xml:lang="en">Summarization: The available Building Energy Management Systems (BEMS), although
            they contribute to a significant reduction of energy consumption and improvement of the indoor environment,
            they can only be implemented in new buildings. Their installation in existing buildings is far from being
            cost effective due to the incompatibility of communication protocols between BEMS designed by various
            manufacturers and unavoidable modifications for data transmission. On the other hand, current research for
            energy efficient buildings has proved that although the design and the facilities including BEMS aim to
            satisfy the thermal and visual comfort plus the air quality demands while minimising the energy needs, they
            often do not reach their goals due to users interference. Latest trends in designing Intelligent Building
            Energy Management Systems (IBEMS) offer a Man Machine Interface that could store the users preferences and
            adapt the control strategy accordingly. The objectives of the present paper are to present the advantages of
            the use of a man machine interface based on a smart card terminal together with fuzzy control techniques in
            satisfying the users preferences plus to underline the capabilities that the LON network offers to the
            design. A fuzzy PID controller is developed to reach the first of the above objectives. The monitoring of
            the energy consumption along with satisfying the users preferences is achieved by the use of a suitable cost
            function for the whole system. All the above parameters as well as the cost function are kept between
            acceptable limits. The overall control system including the cost function is modeled and tested using
            MATLAB/SIMULINK. The implementation of the control system in an existing building requires interconnection
            of sensors and actuators installed across the building, is well served by the LonWorks technology due to its
            high standards and flexibility features.

          <dc:description xml:lang="en">Summarization: In this paper, an optimized fuzzy controller is presented for the
            control of the environmental parameters at the building zone level. The occupants’ preferences are monitored
            via a smart card unit. Genetic algorithm optimization techniques are applied to shift properly the
            membership functions of the fuzzy controller in order to satisfy the occupants’ preferences while minimizing
            energy consumption. The implementation of the system integrates a smart card unit, sensors, actuators,
            interfaces, a programmable logic controller (PLC), local operating network (LON) modules and devices, and a
            central PC which monitors the performance of the system. The communication of the PLC with the smart card
            unit is performed using an RS 485 port, while the PLC-PC communication is performed via the LON network. The
            integrated system is installed and tested in the building of the Laboratory of Electronics of the Technical
            University of Crete.

          <dc:description xml:lang="en">Summarization: Video sensors become particularly important in traffic
            applications mainly due to their fast response, easy installation, operation and maintenance, and their
            ability to monitor wide areas. Research in several fields of traffic applications has resulted in a wealth
            of video processing and analysis methods. Two of the most demanding and widely studied applications relate
            to traffic monitoring and automatic vehicle guidance. In general, systems developed for these areas must
            integrate, amongst their other tasks, the analysis of their static environment (automatic lane finding) and
            the detection of static or moving obstacles (object detection) within their space of interest. In this paper
            we present an overview of image processing and analysis tools used in these applications and we relate these
            tools with complete systems developed for specific traffic applications. More specifically, we categorize
            processing methods based on the intrinsic organization of their input data (feature-driven, area-driven, or
            model-based) and the domain of processing (spatial/frame or temporal/video). Furthermore, we discriminate
            between the cases of static and mobile camera. Based on this categorization of processing tools, we present
            representative systems that have been deployed for operation. Thus, the purpose of the paper is threefold.
            First, to classify image-processing methods used in traffic applications. Second, to provide the advantages
            and disadvantages of these algorithms. Third, from this integrated consideration, to attempt an evaluation
            of shortcomings and general needs in this field of active research.

          <dc:description xml:lang="en">Summarization: Solar thermal technologies (STTs) are mature in many EU Member
            States. However, in some EU regions solar applications, and especially the innovative ones (such as solar
            heating/cooling, solar drying, solar-powered desalination), remain at an early stage. The degree of
            development of each market does not depend on climate conditions (e.g., insolation) or on different
            technological developments. The major strengths, weaknesses, opportunities and threats of STTs are examined,
            in order to identify the most important actions that should be taken to reduce existing barriers, as opposed
            to RTD (Research and Technology Development) of the new STTs. These include financing schemes, publications,
            electronic dissemination tools, campaigns, events, creation of information centres, audits and studies.

          <dc:description xml:lang="en">Summarization: Battery management systems (BMSs) are used in many
            battery-operated industrial and commercial systems to make the battery operation more efficient and the
            estimation of battery state nondestructive. The existing BMS techniques are examined in this paper and a new
            design methodology for a generalized reliable BMS is proposed. The main advantage of the proposed BMS
            compared to the existing systems is that it provides a fault-tolerant capability and battery protection. The
            proposed BMS consists of a number of smart battery modules (SBMs) each of which provides battery
            equalization, monitoring, and battery protection to a string of battery cells. An evaluation SBM was
            developed and tested in the laboratory and experimental results verify the theoretical expectations.

          <dc:description xml:lang="en">Summarization: Cement industry is facing growing challenges in conserving
            materials and conforming to the demanding environ-mental standards. Therefore, there is great interest in
            the development, investigation and use of binders alternatives to Portland cement. Natural hydraulic lime
            (NHL) binders have become nowadays materials with high added value, due to their advantages in various
            construction applications. Some of them include compatibility, suitability, workability and the versatility
            in applications. NHL binders are made from limestones which contain sufficient argillaceous or siliceous
            components fired at relatively low temperatures, with reduction to powder by slaking with or without
            grinding. This study is focused in developing technology for small-scale production of cementitious binders,
            combining the knowledge and experience of geologists and mineral resources engineers. The first step of
            investigation includes field techniques to the study the lithology, texture and sedimentary structure of
            Neogene carbonate sediments, from various basins of Crete Island, Greece and the construction of 3D
            geological models, in order to determine the deposits of each different geological formation. Sampling of
            appropriate quantity of raw materials is crucial for the investigation. Petrographic studies on the basis of
            the study of grain type, grain size, types of porosity and depositional texture, are necessary to classify
            effectively industrial mineral raw materials for this kind of application. Laboratory tests should also
            include the study of mineralogical and chemical composition of the bulk raw materials, as well as the
            content of insoluble limestone impurities, thus determining the amount of active clay and silica components
            required to produce binders of different degree of hydraulicity. Firing of the samples in various
            temperatures and time conditions, followed by X-ray diffraction analysis and slaking rate tests of the
            produced binders, is essential to insure the beneficiation of their behavior. Beneficiation is defined as
            the implementation of the best available techniques to insure the production of an economically usable final
            product which combines both the hydraulicity of the silicates, aluminates and ferrites, as well as the
            reactivity of the calcium oxide amounts that are present.

          <dc:description xml:lang="en">Summarization: A new method for identifying the trioctahedral smectites
            saponite, stevensite and hectorite is proposed in this study. The method is based on differences in the
            X-ray diffraction (XRD) patterns of the three smectites after (a) heating at 500°C for 90 min and (b)
            glycerol solvation of the Cs-forms of the smectites for 20 h. After heating at 500°C, well below the
            dehydroxylation temperature of the three smectites, saponite and hectorite re-expand upon ethylene glycol
            (EG) solvation, whereas stevensite layers remain collapsed. Saponite forms one-layer and hectorite two-layer
            complexes after Cs-saturation and glycerol solvation. Cs-stevensite displays a gradual increase in d 001
            with increasing solvation time in glycerol vapours and forms two-layer glycerol complexes with prolonged
            solvation. Except for the individual Mg-smectites, the proposed method may be used to identify compositional
            heterogeneity that may exist in the smectites. Furthermore, it should be useful in identifying the
            individual trioctahedral Mg-smectites when present in mixtures, and in detecting interstratified layers of
            different Mg-trioctahedral smectites. Application of the method revealed that the SYnL-1 laponite (CMS
            Source Clay Project) is not homogeneous but consists of hectorite, stevensite and possibly mixed-layer
            hectorite/stevensite layers.

            the controlling depositional environment is crucial for optimal quality upgrading and for prioritizing
            potential exploitation areas. In the present work, the quality of El-Tih kaolin, Egypt, was investigated
            using the chemical/mineralogical characteristics as well as the field observations of the clay. Chemical
            analysis of major oxides was carried out using energy dispersive X-ray fluorescence (EDS-XRF) spectrometry.
            Mineralogical analyses were carried out using X-ray diffraction (XRD) and scanning electron microscopy
            coupled with wavelength-dispersive X-ray spectroscopy (SEM-WDS). Spatial heterogeneity of the quality was
            evaluated applying kriging geostatistical techniques and potential zones were identified.

          <dc:description xml:lang="en">Summarization: The Tertiary basin of Feres consists of sedimentary rocks,
            andesitic-rhyolitic volcanic rocks of K-rich calc-alkaline affinities, rocks with calc-alkaline and
            shoshonitic affinities and volcaniclastic fall and flow deposits. Volcanic and volcaniclastic rocks have
            variable concentrations of LIL elements (Ba, Sr, Rb, Th) and HFS elements (Zr, V) due to their mode of
            origin. The pyroclastic flows frequently show more or less intense devitrification, vapour-phase
            crystallization and, in some cases, evidence of fumarolic activity, as is indicated by the presence of
            scapolite. The volcanic and volcaniclastic rocks display various types of alteration including formation of
            zeolites (clinoptilolite, heulandite, mordenite, and laumontite) and smectite, as well as hydrothermal
            alteration (development of silicic, argillic, sericitic and propylitic zones) associated with polymetallic
            mineralization. The behaviour of chemical elements during alteration varies. Some are immobile and their
            distribution is controlled by the conditions prevailing during parent-rock formation and emplacement, but
            others, such as Ba and Sr, are mobile and selectively fractionate in zeolite extra-framework sites. The
            formation of zeolite from alteration of volcanic glass is accompanied by an increase in Mg and Al content,
            and a decrease in Si and Na content, whereas Ca is not affected by alteration. In certain pyroclastic flows,
            there is a significant difference in K-content between incipient glass and altered rock, due to K-feldspar
            formation during devitrification and vapour-phase crystallization.

          <dc:description xml:lang="en">Summarization: The validity of the structural formula (SF) method for
            calculation of layer charge of smectites is examined through re-interpretation of
            published data, which suggest that the SF method overestimates layer charge. The overestimation of layer
            charge by SF is based on assumptions
            about the permanent CEC (CECperm) of smectites i) on the association of the molar mass of half unit cell
            (MHUC) with the CECperm of the smectitic
            clay fraction and ii) on imbalanced SF calculated for a series of used smectites. The CECperm of smectites
            should not be determined at pH 4
            because of competitive adsorption of H+ cations at exchangeable sites. This was verified by monitoring the
            pH of acidified smectite suspensions.
            Instead the pH at the isoelectric point (iep) should be used for determination of permanent charge of
            smectites. Moreover it is suggested that the
            equation of Lagaly [Lagaly, G., 1994. Layer charge determination by alkylammonium ions. In: Mermut, A.R.
            (Ed.), Layer Charge Characteristics
            of 2:1 Silicate Clay Minerals. CMS Workshop lectures, vol. 6. The Clay Minerals Society, Boulder Colorado,
            pp. 2–46] which relates the smectite
            content with layer charge may be used only if CECperm is calculated on a totally anhydrous basis, otherwise
            it may lead to significant
            underestimation either of smectite content or of layer charge.

          <dc:description xml:lang="en">Summarization: Thermodynamic calculations of ion exchange for divalent cations
            were made for clinoptilolite in natural state and after
            irradiation with three different doses of β-radiation (1012, 1015 and 3 × 1016 e/cm2) and γ-radiation (70
            Mrad). The samples were
            equilibrated with binary systems of divalent cations, namely Sr2+ ↔ 2Na+, Ca2+ ↔ 2Na+ and Mg2+ ↔ 2Na+ at 25
            ◦C and total
            solution normality of 0.025 N. The selectivity order Sr2+ &gt; Ca2+ &gt; Mg2+ was observed in non-irradiated
            clinoptilolite. After
            irradiation with γ-radiation the affinity of clinoptilolite for Sr2+ increased and that for Mg2+ decreased,
            whereas the affinity for
            Ca2+ remained unchanged. Irradiation with β-radiation influences selectivity order and clinoptilolite
            affinity decreases for Sr2+,
            whereas it increases for Ca2+. For the sample irradiated with maximum dose of β-radiation the selectivity
            was almost identical
            for Ca2+ and Sr2+. The crystallographic parameters and exchangeable cation site coordinates were refined for
            all samples with
            the Rietveld method. The structure refinement of Sr2+-saturated samples yielded changes both in exchangeable
            sites and site
            occupancy in channels A and B after irradiation with β-and γ-radiation. The cation sites Sr1 and Sr3 exhibit
            major changes both
            in site coordinates and site occupancy after irradiation with β-radiation. In addition, irradiation with
            γ-radiation yielded major
            changes in Sr1 occupancy, whereas coordinates changed only slightly. These structural modifications control
            the observed changes
            in thermodynamic parameters after irradiation.

            mica planes in crystals from
            central Switzerland and Crete, Greece, reveal that domains of paragonite, margarite, and muscovite
            are ordered within the basal plane. Energy dispersive X-ray analyses show that both cations in the
            interlayer and in the 2:1 layer have ordered on the scale of tens to hundreds of nanometers. Domain
            boundaries can be both sharp and crystallographically controlled or diffuse and irregular. A model
            outlining the domain formation process is presented that is consistent with X-ray powder diffraction
            and transmission electron microscopy data. The domain model incorporates aspects of a mixedlayered
            and a disordered compositionally intermediate phase models. The main feature of the model
            is the formation of mica species that segregate within the basal plane and contradict the notion of
            homogeneous layers within mixed-layer phases. Implications for the formation of all diagenetic and
            very low-grade metamorphic 2:1 sheet silicates are discussed

            respectively. Irradiated samples with β-radiation 1012, 1015, 3 × 1016 e/cm2 and 70 Mrad γ-radiation
            yielded ΔG° and lnKα –7.41, –8.83, –8.60, –8.25 kJ/equiv and 2.99, 3.57, 3.47, 3.33 for Cs+ ↔ Na+,
            respectively. Remarkable amorphization of clinoptilolite was observed after exposure at the highest
            dose of β-radiation (3 × 1016 e/cm2) with a concomitant decrease in cation-exchange capacity (CEC).
            Crystallographic parameters and especially exchangeable cation site coordinates were refi ned for all
            samples with the Rietveld method. Cesium-saturated samples exhibited changes in the cation sites
            Cs2 and Cs3, which are next to clinoptilolite channel walls with lower Al3+ for Si4+ substitution. The
            observed changes include a shift in cation sites Cs2 and Cs3 toward channel walls and occupancy
            decrease in site Cs2.

          <dc:description xml:lang="en">Summarization: The Tertiary volcano-sedimentary sequence of the Feres basin
            (Thrace, NE Greece), includes lavas of andesitic–rhyolitic composition as well as volcaniclastic rocks,
            pyroclastic flows and pyroclastic fall deposits principally of dacitic–rhyodacitic composition. The
            pyroclastic flow deposits frequently show intense devitrification, vapour-phase crystallization and evidence
            of fumarolic activity, which involves deposition of scapolite in pore spaces. The Feres basin can be
            subdivided on the basis of mineral alteration assemblages: (1) the Pefka region; characterized by intense
            hydrothermal alteration of the volcanic rocks and mineral zoning (silicic, arg illic, sericitic and
            propylitic zones) with polymetallic mineralization, and (2) the remainder of the basin; where the
            volcaniclastic rocks are characterized by the alteration of volcanic glass to zeolites (clinoptilolite,
            heulandite, mordenite, analcime), clay minerals (smectite, illite, celadonite, chlorite), SiO2 polymorphs
            (cristobalite, opal-CT, quartz), K-feldspar and calcite. Laumontite is also present as an alteration product
            of plagioclase, with stilbite sporadically occurring in veinlets. Locally, rhyolites are also altered to
            zeolites (clinoptilolite and/or mordenite). The zeolitization process has occurred rapidly with the
            depositional environment, temperature, rate of cooling (of the volcanic rocks), nature and temperature of
            the mineral-forming fluids and composition of the parent material controlling the formation of zeolites.

            characteristics of water–bentonite suspensions and to minimize formation
            damage at high temperatures was studied. Twenty-six lignite samples from various peat/lignite deposits in
            Greece were used together
            with a commercial lignite product. The contents of humic and fulvic acids, humins, oxygen, ash and the
            cation exchange capacity of
            lignite samples were examined with respect to fluid loss of these suspensions. The results show that most
            samples provided very good
            filtration control of the water–bentonite suspensions after exposure to 177 C with some being superior to
            the commercial product. Better
            performance was observed after addition of 3% w/v lignite. Total humic and fulvic acids as percentage of dry
            lignite matter and the
            organic matter as lignite percentage showed a weak inverse correlation with the fluid loss volumes.

            6.42% w/w water–bentonite suspensions exposed to high
            temperatures has been studied, using twenty six lignites from various basins in Greece with variable organic
            and inorganic contents
            at concentrations of 0.5% and 3.0%. The lignite-free bentonite suspensions thickened considerably when
            heated at 177 °C for 16 h,
            as was indicated by a two-fold increase of the yield stress, when compared to samples hydrated only at room
            temperature. However
            plastic viscosity did not change appreciably. Full flow curves showed a Herschel–Bulkley behavior of all
            suspensions. Addition of
            lignite maintained the stability of the suspensions exposed to high temperatures (177 °C) by keeping the
            yield stress low and did
            not affect plastic viscosity. Some of the Greek lignites performed equally well with a commercial lignite
            product and improvements
            of 80 to 100% of the stability of the suspensions, compared to lignite-free suspensions, have been found.
            Lignite addition also
            lowered yield stresses for the hydrated samples. No specific trends have been identified between the
            effectiveness of lignites to
            stabilize bentonite suspensions and their humic and fulvic acids and humins content. However, those lignites
            with highest humic
            and fulvic acid contents have maximum stabilization capacity. Similarly, no specific trends have been
            observed between the
            stabilization capacity of lignites and their inorganic components such as oxygen and ash content and also
            with the cation exchange
            capacity. The effectiveness of the Greek lignites to stabilize bentonite suspensions is very high and the
            minor differences in the
            efficiency of the different lignites cannot be attributed solely to any specific component

          <dc:description xml:lang="en">Summarization: The influence of layer charge and charge distribution of
            dioctahedral smectites on the rheological and swelling properties of
            bentonites is examined. Layer charge and charge distribution were determined by XRD using the LayerCharge
            program [Christidis,
            G.E., Eberl, D.D., 2003. Determination of layer charge characteristics of smectites. Clays Clay Miner. 51,
            644–655.]. The
            rheological properties were determined, after sodium exchange using the optimum amount of Na2CO3, from free
            swelling tests.
            Rheological properties were determined using 6.42% suspensions according to industrial practice. In
            smectites with layer charges
            of −0.425 to −0.470 per half formula unit (phfu), layer charge is inversely correlated with free swelling,
            viscosity, gel strength,
            yield strength and thixotropic behaviour. In these smectites, the rheological properties are directly
            associated with the proportion of
            low charge layers. By contrast, in low charge and high charge smectites there is no systematic relation
            between layer charge or the
            proportion of low charge layers and rheological properties. However, low charge smectites yield more viscous
            suspensions and
            swell more than high charge smectites. The rheological properties of bentonites also are affected by the
            proportion of tetrahedral
            charge (i.e. beidellitic charge), by the existence of fine-grained minerals having clay size, such as
            opal-CT and to a lesser degree by
            the ionic strength and the pH of the suspension. A new method for classification of smectites according to
            the layer charge based on
            the XRD characteristics of smecites is proposed, that also is consistent with variations in rheological
            properties. In this
            classification scheme the term smectites with intermediate layer charge is proposed.

          <dc:description xml:lang="en">Summarization: The influence of grinding on colour and particle-size properties
            of talc and smectite
            from a white bentonite were studied and compared with a fine-grained calcite from a chalk. Grinding
            decreased the grain size of all three minerals. The crystallite size and structure of smectite was not
            affected but the crystallite size of talc decreased. The Si–O–Mg and MgO bonds of talc were
            disrupted and cation exchange capacity increased with increasing grinding. Delamination of talc
            crystallites was observed in the initial stages of grinding, whereas with more intense treatment,
            amorphous material was formed. Comminution improved the colour properties of all three minerals,
            namely brightness, L* (lightness) and DE*ab (deviation from perfect white diffuser). Grinding time
            exerts greater influence on the reflectance from calcite surfaces than from clay minerals. This
            difference is attributed to continuous formation of progressively smaller diffuse reflection units
            forming a smoother calcite surface. Decrease of grain size does not form considerably smaller diffuse
            reflection units in clay minerals unless delamination takes place. With prolonged grinding,
            amorphization forms additional diffuse reflection units and a smoother surface due to comminution.

          <dc:description xml:lang="en">Summarization: A new method for calculation of layer charge and charge
            distribution of smectites is proposed.
            The method is based on comparisons between X-ray diffraction (XRD) patterns of K-saturated, ethylene
            glycol-solvated, oriented samples and calculated XRD patterns for three-component, mixed-layer systems.
            For the calculated patterns it is assumed that the measured patterns can be modeled as random
            interstratifications of fully expanding 17.1 A Ê layers, partially expanding 13.5 A Ê layers and
            non-expanding
            9.98 AÊ layers. The technique was tested using 29 well characterized smectites. According to their XRD
            patterns, smectites were classified as group 1 (low-charge smectites) and group 2 (high-charge smectites).
            The boundary between the two groups is at a layer charge of –0.46 equivalents per half unit-cell. Lowcharge
            smectites are dominated by 17.1 AÊ layers, whereas high-charge smectites contain only 20% fully
            expandable layers on average. Smectite properties and industrial applications may be dictated by the
            proportion of 17.1 AÊ layers present. Non-expanding layers may control the behavior of smectites during
            weathering, facilitating the formation of illite layers after subsequent cycles of wetting and drying. The
            precision of the method is better than 3.5% at a layer charge of –0.50; therefore the method should be
            useful for basic research and for industrial purposes.

          <dc:description xml:lang="en">Summarization: The mechanism of decolorization of crude maize and sunflower oils
            was studied by means of
            adsorption of b-carotene by a low-grade bentonite , containin g mixed-layered illite-smectite.
            Decolorization depends on temperature and the time required for equilibrium decreases with increasing
            temperature. The study of the kinetics of adsorption showed that decolorization of maize oil is a
            first-order
            process which occurs in two steps: a first fast step with higher activation energy (25.6 kJ mol –1),
            indicating the influence of a chemical interaction between the pigment and the clay surface, followed by a
            second slow step with low activation energy (12.3 kJ mol –1), characteristic of physical adsorption on the
            previously adsorbed molecules. Decolorization of sunflower oil is also a first-order process, described by a
            single mechanism with intermediate activation energy (19.0 kJ mol –1). Adsorption isotherms of
            decolorization of maize oil follow the Freundlich equation, indicating the existence of heterogeneous
            adsorption sites on the solid’s surface. Heterogeneity is attributed both to different active centers on the
            smectite surface (Bro¨ nsted and Lewis centers) and to the different phases present in bentonite, such as
            illitic layers and clinoptilolite, which also have active centers on their surfaces.

            ato 700-1100°C for 1-4 hours yielded very reactive lime end products. Lime formation was monitored by means
            of kinetic curves and TTT diagrams. Particle size seems to control th onset of lime crystallization at low
            temperatures, but it is of minor importance at higher temparatures. With the experimental setting used, lime
            formation was completed at 900°C. The specific surface area of the end products increases with firing
            temperature up to 800°C, decreasing thereafter. Decrepitation of lime increases gradually with firing
            temperature. Hydration temperature during slaking increases rapidly up to 900°C being constant thereafter.
            Sintering and production of fines during control the physical properties of lime.

          <dc:description xml:lang="en">Summarization: This paper examines the ion-exchange properties of synthetic
            zeolite Na-P0, which was pro- duced from perlite-waste fines and has a SiO2:A1203 ratio of 4.45:1 and a
            cation-exchange capacity (CEC) of 3.95 meq g ~. Although equilibrium is attained rapidly for all three
            metals, exchange is incomplete, with At(max) (maximum equilibrium fraction of the metal in the zeolite)
            being 0.95 for Pb, 0.76 for Zn, and 0.27 for Ni. In both Na ~ ␣89 and Na --* ␣89 exchange, the normalized
            selectivity coefficient is virtually constant for :~A~(normalized equilibrium fraction of the metal in the
            zeolite) values of --&lt;0.6, suggesting a pronounced homogeneity of the available exchange sites. The Gibbs
            standard free energy, AG~ of the Na ---)␣89 exchange calculated from the normalized selectivity coefficient
            is -3.11 kJ eq and, for the Na ~ 1/2Znexchange, it is 2.75 kJ eq ~.
            Examination of the solid exchange products with X-ray diffraction (XRD) revealed a possible decrease in
            crystallinity of zeolite Pb-Pc as suggested by the significant broadening and disappearance of diffraction
            lines. This decrease is associated with a reduction of pore opening, as indicated from Fourier-transform
            infrared analysis (FTIR), which in turn results in a decrease of the amount of zeolitic water. Thermogra-
            vimetric-differential thermogravimetric (TG-DTG) analysis showed that water loss occurs in three steps, the
            relative significance of which depends on the type of exchangeable cation and subsequently on the type of
            complex formed with the cation and/or the zeolite channels. Zeolite Na-Pc might be utilized in environmental
            applications, such as the treatment of acid-mine drainage and electroplating effluents.

          <dc:description xml:lang="en">Summarization: Bentonite deposits of Kimolos Island, Aegean, Greece were
            investigated in order to determine their physical and chemical properties. Testing included measurement of
            CEC (cation exchange capacity), swelling capacity, pH, rheological properties and some important foundry
            properties including green and dry compression strength, shatter index, wet tensile strength, compactability
            and permeability. The rheological and foundry properties are mainly influenced by the bentonite grade
            (smectite content) and the degree of disaggregation of the smectite quasicrystals due to the nature of the
            interlayer cation, the presence of mordenite and undevitrified glass shards, the degree of the oxidation of
            iron and the type of smectite–opal-CT interaction. Na-activation improves green compressive strength and
            especially wet tensile strength and decreases permeability, while its influence on the remaining foundry
            properties is unpredictable. Swelling properties are affected by bentonite grade, expressed by CEC, and the
            presence of characteristic phases (glass shards and opal-CT) decreases swelling, while zeolites increase
            CEC. The swelling capacity is closely related to the CEC, if smectite chemistry is controlled. It is shown
            that although the presence of zeolites like mordenite or small amounts of opal-CT may not affect rheological
            properties, the bonding properties always deteriorate. However, the presence of undevitrified glass reduces
            viscosity.

          <dc:description xml:lang="en">Summarization: Acid activation with HCl of two bentonites from the Aegean
            Islands of Milos and Chios, Greece, consisting of Chambers and Tatatilla-type and Otay-type montmorillonite,
            respectively, resulted in a 4 to 5-fold increase of the surface area of the raw materials. The activated
            materials have been rendered suitable for decolorization (bleaching) of rapeseed oil through removal of
            β-carotene. The optimum bleaching capacity is not associated with maximum surface area. Activation is
            characterized by destruction of the original smectite structure, removal of octahedral cations, uptake of
            OH− and formation of au amorphous Si-rich phase. Mg is the most readily removed element affecting the
            tendency for activation. The Otay-type montmorillonites are activated. more easily. Optimum conditions for
            activation are obtained using a variety of combinations of acid strength and residence time. The combination
            which is likely to be preferred on an industrial scale, is the least energy consuming. Therefore shorter
            treatments with more dilute acid are preferable.

          <dc:description xml:lang="en">Summarization: Some of the Lower Pleistocene bentonites of Milos and Kimolos
            islands, Greece, are valued for their white colour and physicochemical
            properties. They contain opal-CT and, sometimes, zeolite along with smectite, and have been derived from the
            alteration of
            rhyolitic volcanic rocks. The Miloan white bentonites contain Tatatilla-type montmorillonite and beidellite.
            The Kimolian
            ones have Chambers-type montmorillonite. The alteration process involved removal of alkalis and uptake of
            Mg, probably from
            sea water. Si is either redistributed or partially removed. The Kimolian white bentonites have higher
            brightnesses, L* and whiteness index values, and lower yellowness index and ΔE*ab values compared with the
            Miloan ones. The variations in white colour are inversely related to the abundance of Fe oxides
            and anatase, the occurrence of Fe in the smectite structure and its oxidation state. The presence of silica
            minerals is not
            an important factor affecting colour, but is undesirable since it imparts high abrasiveness in commercial
            products. The formation
            of white bentonites of high quality requires the removal of alkalis and silica during alteration of acid
            volcanics in order
            to avoid crystallization of zeolites and opal-CT. Fe needs to be incorporated into the smectite structure.
            Such conditions
            are rarely attained.

          <dc:description xml:lang="en">Summarization: The aim of this research was to design a solar heated reactor
            system to enhance the anaerobic treatment of wastewater or biological
            sludge at temperatures higher than the ambient air temperature. For the proposed reactor system, the solar
            energy absorbed by flat plate
            collectors was transferred to a heat storage tank, which continuously supplied an anaerobic-filter reactor
            with water at a maximum temperature
            of 35 C. The packed reactor was a metallic cylindrical tank with a peripheral twin-wall enclosure. Inside
            this enclosure was
            circulated warm water from the heat storage tank. Furthermore, a mathematical model was developed for the
            prediction of the temperature
            distribution within the reactor under steady state conditions. Preliminary results based on model
            simulations performed with meteorological
            data from various geographical regions of the world suggested that the proposed solar reactor system could
            be a promising
            and environmentally friendly approach for anaerobic treatment of wastewater and biological sludge.

            of 3.68 kPa applied to the inlet of the monolayer. Ganglia mobilization experiments
            were conducted with a constant acoustic wave frequency of 125 Hz and acoustic pressure
            amplitudes ranging from 0 to 39.07 kPa. Effluent dissolved PCE concentrations were
            observed to increase in the presence of acoustic waves with the greatest increase (over
            300%) occurring at the lowest frequency employed (75 Hz). Acoustic waves were also
            observed to mobilize otherwise immobile PCE ganglia, break them apart, and further
            enhance dissolution.

          <dc:description xml:lang="en">Summarization: This paper presents the results from a well-defined,
            circular-shaped, multicomponent dense nonaqueous phase liquid (DNAPL) pool dissolution
            experiment conducted in a three-dimensional, bench scale model aquifer. The multicomponent pool is a mixture
            of tetrachloroethylene
            (PCE) and 1,1,2-trichloroethane (1,1,2-TCA); PCE was the major component and 1,1,2-TCA was the minor
            component. Downgradient plume
            concentrations were measured at five specific locations over time until the majority of the 1,1,2-TCA was
            depleted from the DNAPL pool
            source. The experimental results suggest distinct spatial-temporal plume patterns for minor DNAPL components
            versus major DNAPL components.
            The downgradient concentration varied over time for 1,1,2-TCA while a stable plume developed for PCE. A
            semi-analytical solution
            for contaminant transport resulting from dissolution of multicomponent nonaqueous phase liquid pools
            successfully simulated the plume
            structure and dynamics for both the major and minor DNAPL components.

          <dc:description xml:lang="en">Summarization: The impact of acoustic pressure waves on multicomponent
            nonaqueous phase liquid (NAPL) ganglia dissolution in
            water saturated columns packed with glass beads was
            investigated. Laboratory data from dissolution experiments
            with two and three component NAPL mixtures suggested
            that acoustic waves significantly enhance ganglia dissolution
            due to the imposed oscillatory interstitial water velocity.
            The dissolution enhancement was shown to be directly
            proportional to the acoustic wave frequency. Furthermore,
            it was demonstrated that the greatest dissolution
            enhancement in the presence of acoustic waves is
            associated with the component of the NAPL mixture having
            the smallest equilibrium aqueous solubility. Finally,
            square shaped acoustic waves were shown to lead to
            greater NAPL dissolution enhancement compared to
            sinusoidal and triangular acoustic waves. The results of
            this study suggested that aquifer remediation using acoustic
            waves is a promising method particularly for aquifers
            contaminated with NAPLs containing components with
            very low equilibrium aqueous solubilities.

          <dc:description xml:lang="en">Summarization: In this work, the transport of dense colloids through a
            water-saturated, bifurcating fracture is investigated using a constant spatial step
            particle tracking technique. The size of the constituents of a colloid plume is an important factor
            affecting the partitioning of dense colloids
            at the bifurcation. While neutrally buoyant colloids partition between daughter fractures in proportion to
            flow rates, dense colloids will
            preferentially exit fractures that are gravitationally downgradient, notwithstanding that the majority of
            the interstitial fluid may flow through
            the upper fracture. Comparison of the partitioning ratio between daughter fractures with the ratios of
            characteristic settling, diffusion, and
            advection time reveal that these parameters control how colloids behave at fracture bifurcations.

          <dc:description xml:lang="en">Summarization: In this work we derive expressions for the effective velocity and
            effective dispersion coefficient for finite-sized spherical particles with
            neutral buoyancy flowing within a water saturated fracture. We considered the miscible displacement of a
            fluid initially free of particles by
            another fluid containing particles of finite size in suspension within a fracture formed by two
            semi-infinite parallel plates. Particle spreading
            occurs due to the combined actions of molecular diffusion and the dispersive effect of the Poiseuille
            velocity profile. Unlike Taylor dispersion,
            here the finite size of the particles is taken into account. It is shown that because the finite size of a
            particle excludes it from the slowest
            moving portion of the velocity profile, the effective particle velocity is increased, while the overall
            particle dispersion is reduced. A similar
            derivation applied to particles flowing in uniform tubes yields analogous results. The effective velocity
            and dispersion coefficient derived in
            this work for particle transport in fractures with uniform aperture are unique and ideally suited for use in
            particle tracking models.

            were preflooded with reclaimed wastewater to simulate the
            field conditions of the Nardo` fractured aquifer in the Salento area,
            Italy, where fractures are not clean due to artificial groundwater
            recharge. One of the FAMs was injected with secondary
            effluent from a wastewater treatment plant collected prior to
            the chlorination step and the other with exactly the same effluent,
            which was further treated in a commercial membrane
            reactor. Consequently, the organic and pathogen concentrations
            were considerably higher in the secondary effluent than in
            the membrane reactor effluent. Injected wastewater was
            continuously recirculated. Pathogen removal was greater for
            the secondary wastewater than the cleaner membrane reactor
            effluent. A simple mathematical model was developed to
            describe fracture clogging. The results suggest that the hydraulic
            conductivity of FAMs can be significantly degraded due to
            retention of viable and inactivated biocolloids suspended in
            reclaimed wastewater.

          <dc:description xml:lang="en">Summarization: A mathematical model has been developed to study the cotransport
            of contaminants with colloids in saturated rock fractures. The contaminant is assumed to decay, and sorb on
            to fracture surfaces and on to colloidal particles, as well as to diffuse into the rock matrix; whereas,
            colloids are envisioned to deposit irreversibly on to fracture surfaces without penetration into the rock
            matrix. The governing one-dimensional equations describing the contaminant and the colloid transport in the
            fracture, colloid deposition on to fracture surfaces, and contaminant diffusion into the rock matrix are
            coupled. This coupling is accomplished by assuming that the amount of contaminant mass captured by colloidal
            particles in solution and the amount captured by deposited colloids on fracture surfaces are described by
            modified Freundlich reversible equilibrium sorption relationships, and that mass transport by diffusion into
            the rock matrix is a first-order process. The contaminant sorption on to fracture surfaces is described by a
            linear equilibrium sorption isotherm, while the deposition of colloids is incorporated into the model as a
            first-order process. The resulting coupled contaminant transport non-linear equation is solved numerically
            with the fully implicit finite difference method. The constant concentration as well as the constant flux
            boundary conditions have been considered. The impact of the presence of colloids on contaminant transport is
            examined. According to model simulations the results show that, depending on the conditions of the physical
            system considered, colloids can increase or decrease the mobility of contaminants.

          <dc:description xml:lang="en">Summarization: An analytical solution to the steady-state three-dimensional
            atmospheric dispersion equation
            has been developed for the transport of non-buoyant emissions from a continuous ground-level area source.
            The model incorporates power law profiles for the variation of wind speed and vertical eddy diffusivity with
            height, represents the lateral eddy diffusivity as a function of wind speed and the crosswind dispersion
            coefficient, and includes dry deposition as a removal mechanism. The model is well suited for accurate
            prediction of emission concentration levels in the vicinity of an area source, as well as farther downwind,
            under neutral or stable atmospheric conditions. The impact of the important model parameters on
            contaminant dispersion is examined. The results from several simulations, compared with point and line
            sources of equivalent source strength, indicate that at short downwind distances, predictions of contaminant
            concentrations emitted from area sources may be unacceptably inaccurate unless the structure of the
            source is properly taken into account.

          <dc:description xml:lang="en">Summarization: Closed-form analytical solutions for colloid transport in single
            rock fractures with
            and without colloid penetration into the rock matrix are derived for constant
            concentration as well as constant flux boundary conditions. A single fracture is
            idealized as two semi-infinite parallel plates. It is assumed that colloidal particles
            undergo irreversible deposition onto fracture surfaces and may penetrate into the
            rock matrix, and deposit irreversibly onto rock matrix solid surfaces. The
            solutions are obtained by taking Laplace transforms to the governing transport
            equations and boundary conditions with respect to time and space. For the case
            of no colloid penetration into the rock matrix, the solutions are expressed in terms
            of exponentials and complimentary error functions; whereas, for the case of
            colloid penetration into the rock matrix, the solutions are expressed in terms of
            convolution integrals and modified Bessel functions. The impact of the model
            parameters on colloid transport is examined. The results from several simulations
            indicate that liquid-phase as well as deposited colloid concentrations in the
            fracture are sensitive to the fracture surface deposition coefficient, the fracture
            aperture, and the Brownian diffusion coefficient for colloidal particles penetrating
            the rock matrix. Furthermore, it is shown that the differences between the two
            boundary conditions investigated are minimized at dominant advective transport
            conditions. The constant concentration condition overestimates liquid-phase
            colloid concentrations, whereas the constant flux condition leads to conservation
            of mass.

            transport originating from the
            dissolution of multicomponent nonaqueous phase liquid NAPL pools in three-dimensional,
            saturated, homogeneous porous media is presented. Each dissolved component may undergo
            first-order decay and may sorb under local equilibrium conditions. The NAPL pool dissolution
            . process is envisioned to occur in a series of consecutive short intervals pulses . The mole
            fraction, nonaqueous phase activity coefficient and aqueous solubility of every pool constituent are
            estimated before the initiation of each pulse, and they are assumed to remain constant for the
            duration of each interval. Individual component aqueous phase concentrations resulting from each
            dissolution interval are estimated by existing analytical solutions applicable to single component
            NAPL pools, and total concentration distributions of the same component are obtained by direct
            superposition. The semi-analytical method is more efficient and less computationally demanding
            than a finite-difference approximation. Furthermore, it is shown that neglecting the changes in
            nonaqueous phase activity coefficients that occur during multicomponent NAPL pool dissolution
            may result in erroneous predictions. The model presented in this work is useful for the design and
            interpretation of experiments in laboratory bench scale aquifers, certain homogeneous subsurface
            formations, and for the verification of complex numerical codes.

          <dc:description xml:lang="en">Summarization: The traditional di(usive particle tracking equation provides an
            updated particle location as a function of its previous location
            and molecular di(usion coe cient while maintaining a constant time step. A smaller time step yields an
            increasingly accurate, yet
            more computationally demanding solution. Selection of this time step becomes an important consideration and,
            depending on the
            complexity of the problem, a single optimum value may not exist. The characteristics of the system under
            consideration may be
            such that a constant time step may yield solutions with insu cient accuracy in some portions of the domain
            and excess computation
            time for others. In this work, new particle tracking equations speci%cally designed for the solution of
            problems associated with
            di(usion processes in one, two, and three dimensions are presented. Instead of a constant time step, the
            proposed equations employ
            a constant spatial step. Using a traditional particle tracking algorithm, the travel time necessary for a
            particle with a di(usion
            coe cient inversely proportional to its diameter to achieve a pre-speci%ed distance was determined. Because
            the size of a particle
            a(ects how it di(uses in a quiescent 8uid, it is expected that two di(erently sized particles would require
            di(erent travel times to
            move a given distance. The probability densities of travel times for plumes of monodisperse particles were
            consistently found to
            be log-normal in shape. The parameters describing this log-normal distribution, i.e., mean and standard
            deviation, are functions of
            the distance speci%ed for travel and the di(usion coe cient of the particles. Thus, a random number selected
            from this distribution
            approximates the time required for a given particle to travel a speci%ed distance. The new equations are
            straightforward and may be
            easily incorporated into appropriate particle tracking algorithms. In addition, the new particle tracking
            equations are as accurate and
            often more computationally e cient than the traditional particle tracking equation

          <dc:description xml:lang="en">Summarization: Mathematical models are developed for two-dimensional transient
            transport of colloids, and cotransport of contaminant/colloids in a fracture-rock matrix system with
            spatially variable fracture aperture. The aperture in the fracture plane is considered as a lognormally
            distributed random variable with spatial fluctuations described by an exponential autocovariance function.
            Colloids are envisioned to irreversibly deposit onto fracture surfaces without penetrating the rock matrix;
            whereas, the contaminant is assumed to decay, sorb onto fracture surfaces and onto colloidal particles, as
            well as to diffuse into the rock matrix. The governing stochastic transport equations are solved numerically
            for each realization of the aperture fluctuations by a fully implicit finite difference scheme. Emphasis is
            given on the effects of variable aperture on colloid and colloid-facilitated contaminant transport.
            Simulated breakthrough curves of ensemble averages of several realizations show enhanced colloid transport
            and more pronounced fingering when colloids are subject to size exclusion from regions of small aperture
            size. Moreover, it is shown that an increase in the fracture aperture fluctuations leads to faster transport
            and increases dispersion. For the case of contaminant/colloids cotransport it is shown, for the conditions
            considered in this work, that colloids enhance contaminant mobility and increase contaminant dispersion.

          <dc:description xml:lang="en">Summarization:

            A two-dimensional finite difference numerical model was developed to describe the
            transport of dissolved organics originating from nonaqueous phase liquid (NAPL) pool dissolution in
            saturated porous media in the presence of dissolved humic substances. A rectangular NAPL pool was
            considered in a homogeneous porous medium with unidirectional interstitial groundwater velocity.
            It was assumed that dissolved humic substances and aqueous phase contaminants may sorb onto the
            solid matrix under local equilibrium conditions. The contaminant in the aqueous phase may undergo
            first-order decay. Also, the dissolved contaminant may sorb onto humic substances. The transport
            properties of dissolved humic substances are assumed to be unaffected by sorbing contaminants,
            because dissolved humic macromolecules are much larger than dissolved contaminants and sorp-
            tion of nonpolar contaminants onto humic substances do not affect the overall surface charge of
            humic substances. The sorption characteristics of dissolved humic substances onto clean sand were
            determined from column experiments. An effective local mass transfer rate coefficient accounting
            for the presence of dissolved humic substances was developed. Model simulations indicate that
            dissolved humic substances substantially increase NAPL pool dissolution, and consequently reduce
            the required pump-and-treat aquifer remediation time.

            inactivation of suspended and deposited viruses with different inactivation rate coefficients. Virus
            deposition onto solid particles is described by two different processes: nonequilibrium adsorption
            which is applicable to viruses behaving as solutes; and colloid filtration which is applicable to viruses
            behaving as colloids. The governing virus transport equations are solved analytically by employing
            Laplace/Fourier transform techniques. Instantaneous and continuous/periodic virus loadings from

            suspensions in a twodimensional,
            water saturated fracture with spatially variable and anisotropic aperture is investigated
            with a particle tracking model. Both neutrally buoyant and dense colloid suspensions are considered.
            Although flow and transport in fractured subsurface formations have been studied extensively by
            numerous investigators, the transport of dense, polydisperse colloid suspensions in a fracture with
            spatially variable and anisotropic aperture has not been previously explored. Simulated snapshots and
            breakthrough curves of ensemble averages of several realizations of a log-normally distributed aperture
            field show that polydisperse colloids exhibit greater spreading than monodisperse colloids, and
            dense colloids show greater retardation than neutrally buoyant colloids. Moreover, it is demonstrated
            that aperture anisotropy oriented along the flow direction substantially increases colloid spreading;
            whereas, aperture anisotropy oriented transverse to the flow direction retards colloid movement.

          <dc:description xml:lang="en">Summarization: Safe disposal of thermally spent geothermal
            brines that contain environmentally hazardous constituents
            is commonly obtained by reinjection. The reinjection
            process also serves to maintain reservoir pressure, enhance
            thermal recovery, and eliminate possible compactional
            subsidence. To avoid premature thermal breakthrough of
            reinjected fluids, tracer tests are employed for detection
            and evaluation of preferential path networks. In this paper
            some promising tracers that have not received much attention
            in geothermal reservoir studies are discussed, and a
            comprehensive tabulation of field sites of artificial tracer
            utilization is presented. Chemical and transport processes
            responsible for tracer retention by the formation of reservoir
            solids, as well as available tracer detection techniques,
            are emphasized.

          <dc:description xml:lang="en">Summarization: A quasi-three-dimensional particle tracking
            model is developed to characterize the spatial and temporal
            effects of advection, molecular diffusion, Taylor
            dispersion, fracture wall deposition, matrix diffusion,
            and co-transport processes on two discrete plumes
            (suspended monodisperse or polydisperse colloids and
            dissolved contaminants) flowing through a variable
            aperture fracture situated in a porous medium. Contaminants
            travel by advection and diffusion and may
            sorb onto fracture walls and colloid particles, as well as
            diffuse into and sorb onto the surrounding porous rock
            matrix. A kinetic isotherm describes contaminant sorption
            onto colloids and sorbed contaminants assume the
            unique transport properties of colloids. Sorption of the
            contaminants that have diffused into the matrix is governed
            by a first-order kinetic reaction. Colloids travel by
            advection and diffusion and may attach onto fracture
            walls; however, they do not penetrate the rock matrix. A
            probabilistic form of the Boltzmann law describes filtration
            of both colloids and contaminants on fracture
            walls. Ensemble-averaged breakthrough curves of many
            fracture realizations are used to compare arrival times of
            colloid and contaminant plumes at the fracture outlet.
            Results show that the presence of colloids enhances
            contaminant transport (decreased residence times) while
            matrix diffusion and sorption onto fracture walls retard
            the transport of contaminants

          <dc:description xml:lang="en">Summarization: Local mass transfer correlations are developed to describe the
            rate of interface mass transfer
            of single component nonaqueous phase liquid (NAPL) pools in saturated subsurface formations.
            A three-dimensional solute transport model is employed to compute local mass transfer coefficients
            from concentration gradients at the NAPL–water interface, assuming that the aqueous phase concentration
            along the NAPL–water interface is constant and equal to the solubility concentration.
            Furthermore, it is assumed that the porous medium is homogeneous, the interstitial fluid velocity
            steady and the dissolved solute may undergo first-order decay or may sorb under local equilibrium
            conditions. Power-law expressions relating the local Sherwood number to appropriate local Peclet
            numbers are developed for both rectangular and elliptic/circular source geometries. The proposed
            power law correlations are fitted to numerically generated data and the correlation coefficients are
            determined using nonlinear least squares regression. The estimated correlation coefficients are found
            to be direct functions of the interstitial fluid velocity, pool dimensions, and pool geometry.

          <dc:description xml:lang="en">Summarization: A methodology is developed for estimating
            temporally variable virus inactivation rate coefficients
            from experimental virus inactivation data. The methodology
            consists of a technique for slope estimation of
            normalized virus inactivation data in conjunction with
            a resampling parameter estimation procedure. The
            slope estimation technique is based on a relatively
            flexible geostatistical method known as universal kriging.
            Drift coefficients are obtained by nonlinear fitting
            of bootstrap samples and the corresponding confidence
            intervals are obtained by bootstrap percentiles. The
            proposed methodology yields more accurate time dependent
            virus inactivation rate coefficients than those
            estimated by fitting virus inactivation data to a firstorder
            inactivation model. The methodology is successfully
            applied to a set of poliovirus batch inactivation
            data. Furthermore, the importance of accurate inactivation
            rate coefficient determination on virus transport
            in water saturated porous media is demonstrated with
            model simulations

            contaminant transport model is developed to investigate
            the effect of variable hydraulic conductivity on
            average mass transfer coefficients associated with the
            dissolution of dense nonaqueous phase liquid
            (DNAPL) pools in heterogeneous, water-saturated
            subsurface formations. Randomly generated, threedimensional
            hydraulic conductivity fields are used to
            represent a heterogeneous confined aquifer. Model
            simulations indicate that the average mass transfer
            coefficient is inversely proportional to the variance of
            the log-transformed hydraulic conductivity. A power
            law correlation relating the Sherwood number to the
            variance of the log-transformed hydraulic conductivity
            and appropriate Peclet numbers is developed.
            A reasonable fit between predicted and numerically
            determined mass transfer coefficients is observed

          <dc:description xml:lang="en">Summarization: Numerical experiments are conducted to examine the effects of
            gravity on monodisperse and polydisperse
            colloid transport in water-saturated fractures with uniform aperture. Dense colloids travel in
            water-saturated fractures by advection and diffusion while subject to the influence of gravity. Colloids
            are assumed to neither attach onto the fracture walls nor penetrate the rock matrix based on the assumptions
            that they are inert and their size is larger than the pore size of the surrounding solid matrix. Both
            the size distribution of a colloid plume and colloid density are shown to be significant factors impacting
            their transport when gravitational forces are important. A constant-spatial-step particle-tracking code
            simulates colloid plumes with increasing densities transporting in water-saturated fractures while
            accounting for three forces acting on each particle: a deterministic advective force due to the Poiseuille
            flow field within the fracture, a random force caused by Brownian diffusion, and the gravitational force.
            Integer angles of fracture orientation with respect to the horizontal ranging from ±90 are considered:
            three lognormally distributed colloid plumes with mean particle size of 1 lm (averaged on a volumetric
            basis) and standard deviation of 0.6, 1.2 and 1.8 lm are examined. Colloid plumes are assigned densities
            of 1.25, 1.5, 1.75 and 2.0 g/cm3. The first four spatial moments and the first two temporal moments are
            estimated as functions of fracture orientation angle and colloid density. Several snapshots of colloid
            plumes in fractures of different orientations are presented. In all cases, larger particles tend to spread
            over wider sections of the fracture in the flow direction, but smaller particles can travel faster or slower
            than larger particles depending on fracture orientation angle

          <dc:description xml:lang="en">Summarization: A particle tracking model is developed to simulate the transport
            of variably
            sized colloids in a fracture with a spatially variable aperture. The aperture of the fracture
            is treated as a lognormally distributed random variable. The spatial fluctuations of the
            aperture are described by an exponential autocovariance function. It is assumed that
            colloids can sorb onto the fracture walls but may not penetrate the rock matrix. Particle
            advection is governed by the local fracture velocity and diffusion by the Stokes-Einstein
            equation. Model simulations for various realizations of aperture fluctuations indicate that
            lognormal colloid size distributions exhibit greater spreading than monodisperse
            suspensions. Both sorption and spreading of the polydisperse colloids increase with
            increasing variance in the particle diameter. It is shown that the largest particles are
            preferentially transported through the fracture leading to early breakthrough while the
            smallest particles are preferentially sorbed. Increasing the variance of the aperture
            fluctuations leads to increased tailing for both monodisperse and variably sized colloid
            suspensions, while increasing the correlation length of the aperture fluctuations leads to
            increased spreading.

          <dc:description xml:lang="en">Summarization: Analytical solutions to two mathematical models for virus
            transport in
            one-dimensional homogeneous, saturated porous media are presented, for
            constant flux as well as constant concentration boundary conditions,
            accounting for first-order inactivation of suspended and adsorbed (or
            filtered) viruses with different inactivation constants. Two processes
            for virus attachment onto the solid matrix are considered. The first
            process is the nonequilibrium reversible adsorption, which is applicable
            to viruses behaving as solutes; whereas, the second is the filtration
            process, which is suitable for viruses behaving as colloids. Since the
            governing transport equations corresponding to each physical process
            have identical mathematical forms, only one generalized closed-form
            analytical solution is developed by Laplace transform techniques. The
            impact of the model parameters on virus transport is examined. An
            empirical relation between inactivation rate and subsurface temperature
            is employed to investigate the effect of temperature on virus transport.
            It is shown that the differences between the two boundary conditions are
            minimized at advection-dominated transport conditions.

          <dc:description xml:lang="en">Summarization: Transient moisture flow in a variably saturated
            quasi-three-dimensional
            fracture-rock matrix system is investigated. The fracture is assumed to possess a spatially
            variable aperture in its two-dimensional plane, whereas the rock matrix is treated as a
            two-dimensional homogeneous and tight porous medium. The aperture fluctuations in the
            fracture plane are described stochastically. Moisture exchange between the fracture and
            the rock matrix is accounted for via an advective coupling term that governs the transfer
            of moisture at the fracture-matrix interface and takes into account the effect of a fracturesurface
            coating material. Although the variable aperture fracture is two-dimensional, the
            coupling term between the fracture and the rock matrix accounts for the threedimensional
            nature of the physical system. The stochastic nonlinear set of partial
            differential equations is solved numerically by the Galerkin finite element method in
            conjunction with the Picard iterative scheme and an automatic time step marching.
            Simulations are performed to investigate phenomena which have been ignored in previous
            studies. It is demonstrated that, for the case of no moisture exchange with the rock matrix,
            the moisture follows preferential flow paths within the fracture plane and exhibits
            pronounced fingering effects. Furthermore, it is shown that the larger the fracture
            aperture fluctuations the more extended the moisture flow in the fracture. In addition, for
            the case where there exists moisture exchange with the rock matrix, the movement of the
            moisture front is considerably reduced, whereas fracture-surface coatings tend to slow
            down moisture absorption by the rock matrix.

            porous media is developed, accounting for virus sorption and inactivation of liquid phase
            and adsorbed viruses with different time dependent rate coefficients. The virus inactivation
            process is represented by a pseudo first-order rate expression. The pseudo first-order
            approximation is shown to simulate available experimental data from three virus
            inactivation batch studies better than the frequently employed constant rate inactivation
            model. Model simulations indicated that the pseudo first-order approximation, compared
            to the constant inactivation, leads to extended survival of viruses and, consequently, more
            distant migration. Results from a parameter sensitivity analysis demonstrated that
            estimation of pseudo first-order inactivation rate coefficients from field observations
            requires data collection near the source of virus contamination during initial stages of
            virus transport.

          <dc:description xml:lang="en">Summarization: The Lower Pleistocene bentonite deposits of Eastern Milos, Greece
            have been formed at the
            expense of volcaniclastic rocks under submarine conditions. Systematic variation of the major chemical
            elements reveals that the deposits were formed from different precursors which were erupted from different
            volcanic centers belonging to at least two separate volcanic provinces. The volcanic eruptions were
            probably subaqueous. The major authigenic phases are smectite, K-feldspar, opal-CT and the zeolites
            mordenite and clinoptilolite. The deposits have a complex history and have been affected by hydrothermal
            alteration.
            The geological features ofbentonites coupled by the presence of abundant authigenic K-feldspar indicate
            that alteration of the parent volcanoclastic rocks took place under low temperatures and is probably not
            related to hydrothermal alteration, which is a separate event. Hydrothermal alteration has modified both
            the mineralogical characteristics and the properties of bentonites. Alteration of the parent rocks to
            bentonites
            was favoured by high water : wall rock ratios and fluid flow and is associated with leaching and
            subsequent removal of Na, K and Ca. The source of Mg was the parent rocks and only small scale Mguptake
            from the sea water has probably taken place. The formation of authigenic K-feldspar has probably
            been favoured by a high K§ + activity ratio and high Si activity of the pore fluid. Such conditions
            might have been favoured by the pH conditions and the cooling history of the parent rocks.

          <dc:description xml:lang="en">Summarization: Hydrothermal alteration has caused illitization along a 40m
            vertical profile in the Tsantilis
            bentonite deposit, Eastern Milos, Greece which consists principally of a Wyoming-type montmorillonite
            and authigenic K-feldspar. The product K-bentonite which contains illite/smectite, kaolinite, K-feldspar,
            quartz, sulphates and sulphides exhibits an unusual tendency for increase of expandability with depth.
            Mineralogy and I/S textures were determined with X-ray diffraction and SEM and TEM methods
            respectively and chemistry using X-ray fluorescence. Illitization is characterized by a 5- to 6-fold
            increase
            of K and release of Si, Fe, Mg Na, and Ca from the parent rock, indicating a K-influx (K-metasomatism)
            in the system.
            The I/S particle morphology is characterized by both flaky and lath-like particles, the former dominating
            in the range 100-50% expandable layers (R0 ordering) and the latter in the range 50-10% expandable
            layers (R1 and R &gt; 1 ordering). Flaky particles are also abundant in samples with R1 ordering and
            abundant kaolinite, indicating that the latter might affect illitization. The I/S particles are classified
            in
            populations with thickness multiples of 10 A, their thickness being probably smaller than the coherent
            XRD domain. As the reaction proceeds, particles grow thicker and more equant. The distribution of I/S
            particle dimensions forms steady state profiles showing log-normal distribution; however, sensu stricto
            Ostwald ripening is unlikely. It seems that the reaction proceeds toward minimization of the surface free
            energy of I/S, being affected principally by temperature and K-availability. The spatial distribution of
            expandability implies that the heating source was probably a mineralized vein with T &lt; 200~ directed
            away from the bentonite, suggesting that illitization might be used as an exploration guide for mineral
            deposits.

          <dc:description xml:lang="en">Summarization: he Web of Data is an open environment consisting of a great
            number of large inter-linked RDF datasets from various domains. In this environment, organizations and
            companies adopt the Linked Data practices utilizing Semantic Web (SW) technologies, in order to publish
            their data and offer SPARQL endpoints (i.e., SPARQL-based search services). On the other hand, the dominant
            standard for information exchange in the Web today is XML. Additionally, many international standards (e.g.,
            Dublin Core, MPEG-7, METS, TEI, IEEE LOM) in several domains (e.g., Digital Libraries, GIS, Multimedia,
            e-Learning) have been expressed in XML Schema. The aforementioned have led to an increasing emphasis on XML
            data, accessed using the XQuery query language. The SW and XML worlds and their developed infrastructures
            are based on different data models, semantics and query languages. Thus, it is crucial to develop
            interoperability mechanisms that allow the Web of Data users to access XML datasets, using SPARQL, from
            their own working environments. It is unrealistic to expect that all the existing legacy data (e.g.,
            Relational, XML, etc.) will be transformed into SW data. Therefore, publishing legacy data as Linked Data
            and providing SPARQL endpoints over them has become a major research challenge. In this direction, we
            introduce the SPARQL2XQuery Framework which creates an interoperable environment, where SPARQL queries are
            automatically translated to XQuery queries, in order to access XML data across the Web. The SPARQL2XQuery
            Framework provides a mapping model for the expression of OWL–RDF/S to XML Schema mappings as well as a
            method for SPARQL to XQuery translation. To this end, our Framework supports both manual and automatic
            mapping specification between ontologies and XML Schemas. In the automatic mapping specification scenario,
            the SPARQL2XQuery exploits the XS2OWL component which transforms XML Schemas into OWL ontologies. Finally,
            extensive experiments have been conducted in order to evaluate the schema transformation, mapping
            generation, query translation and query evaluation efficiency, using both real and synthetic datasets.

          <dc:description xml:lang="en">Summarization: Natural history museums (NHMs) form a rich source of knowledge
            about Earth’s biodiversity and natural history. However, an impressive abundance of high-quality scientific
            content available in NHMs around Europe remains largely unexploited due to a number of barriers, such as the
            lack of interconnection and interoperability between the management systems used by museums, the lack of
            centralized access through a European point of reference such as Europeana and the inadequacy of the current
            metadata and content organization. The Natural Europe project offers a coordinated solution at European
            level that aims to overcome those barriers. In this article, we present the architecture, deployment and
            evaluation of the Natural Europe infrastructure allowing the curators to publish, semantically describe and
            manage the museums’ cultural heritage objects, as well as disseminate them to Europeana.eu and BioCASE/GBIF.
            Additionally, we discuss the methodology followed for the transition of the infrastructure to the Semantic
            Web and the publishing of NHMs’ cultural heritage metadata as Linked Data, supporting the Europeana Data
            Model.

          <dc:description xml:lang="en">Summarization: This paper aims to describe MoM-NOCS, a Framework and a System
            that support communities with common interests in nature to capture and share multimedia observations of
            nature objects or events using mobile devices. Design/methodology/approach – The observations are
            automatically associated with contextual metadata that allow them to be visualized on top of 2D or 3D maps.
            The observations are managed by a multimedia management system, and annotated by the same and/or other users
            with common interests. Annotations made by the crowd support the knowledge distillation of the data and data
            provenance processes in the system. Findings – MoM-NOCS is complementary and interoperable with systems that
            are managed by natural history museums like MMAT (Makris et al., 2013) and biodiversity metadata management
            systems like BIOCASE (BioCASE) and GBIF (GBIF) so that they can link to interesting observations in the
            system, and the statistics of the observations that they manage can be visualized by the software.
            Originality/value – The Framework offers rich functionality for visualizing the observations made by the
            crowd as function of time.

            makes them a powerful sensor for geographical context related images. They allow wireless connection to
            computers and the images can be automatically transferred to a PC or can be integrated into a GIS system. In
            this paper, we present an approach for personalised spatial information retrieval and visualisation for
            picture databases using ontologies and semantic maps. Ontologies are used in our case to describe domain
            knowledge in relation to spatial coordinates, to enhance image annotation, search capability and information
            visualisation. Individuals from the ontologies are represented by their footprint in semantic maps.
            Personalised semantic maps are constructed selecting ontologies, concept types or individuals that reflect
            the interests of the user. We describe a developed prototype system with a database design for ontologies
            and semantic maps. We demonstrate the automatic image annotation and the visualisation of the spatial
            queries. An application of the system targets the area of culture and tourism and provides a user friendly
            interface.

          <dc:description xml:lang="en">Summarization: We present in this paper the MPEG-7 Query Language (MP7QL), a
            powerful query language that we have developed for querying
            MPEG-7 descriptions, as well as its compatible Filtering and Search Preferences (FASP) model. The MP7QL has
            the MPEG-7 as
            data model and allows for querying every aspect of an MPEG-7 multimedia content description. It allows the
            users to express
            the conditions that should hold for the multimedia content returned to them regarding semantics, low-level
            visual and audio
            features and media-related aspects. The MP7QL queries may utilize the users’ FASP and Usage History as
            context, thus allowing
            for personalized multimedia content retrieval. The FASP model supported is compatible with the MP7QL and has
            the model of
            the standard MPEG-7 FASPs as a special case. The proposed FASPs essentially are MP7QL queries. Both the
            MP7QL and its compatible
            FASP model allow for the exploitation of domain knowledge encoded using pure MPEG-7 constructs. In addition,
            they allow the
            explicit specification of boolean operators and/or preference values in order to allow both the combination
            of the query conditions
            according to the user intentions and the expression of the importance of the individual conditions for the
            users. The MP7QL
            query results are represented as MPEG-7 documents, guaranteeing the closure of the results within the MPEG-7
            space. The MP7QL
            and the FASP model have been expressed using both XML Schema and OWL syntax. An implementation of the MP7QL,
            on top of an
            XML Native Database is currently in progress. A real world-world evaluation study on the expressive power of
            the MP7QL shows
            that it covers both general purpose and domain specific requirements in multimedia content retrieval.

          <dc:description xml:lang="en">Summarization: In this paper, we focus on interoperable semantic multimedia
            services that are offered in open environments such as the Internet. The use of well-accepted standards is
            of paramount importance for interoperability support in open environments. In addition, the semantic
            description of multimedia content utilizing domain ontologies is very useful for indexing, query
            specification, retrieval, filtering, user Interfaces, and knowledge extraction from audiovisual material.
            With the MPEG-7 and MPEG-21 standards dominating the multimedia content and service description domain and
            OWL dominating the ontology description languages, it is important to establish a framework that allows
            these standards to interoperate. We describe here the DS-MIRF framework, a software engineering framework
            that facilitates the development of knowledge-based multimedia applications such as multimedia information
            retrieval, filtering, browsing, interaction, knowledge extraction, segmentation, and content description.
            DS-MIRF supports interoperability of OWL with the MPEG-7/21 so that domain and application ontologies
            expressed in OWL can be transparently integrated with MPEG-7/21 metadata. This allows applications that
            recognize and use the constructs provided by MPEG-7/21 to make use of domain and application ontologies,
            resulting in more effective retrieval and user interaction with the audiovisual material.

            allow the definition and editing of both standard-based and domain OWL ontologies and their use in
            multimedia information system components. In our working environment an OWL Upper Ontology that captures the
            MPEG-7 MDS is utilized and OWL domain ontologies extend the upper ontology with domain knowledge. The
            ontologies imported in GraphOnto are parsed so that graphical ontology browsing and editing interfaces are
            automatically generated. The ontologies are used to guide the semantic multimedia annotation in a
            standardized manner. OWL Ontology mappings, expressed using OWL constructs, are supported and allow the
            definition of personalized ontologies. Personalization of the GraphOnto user interface on the application,
            task and user levels is provided. In addition, GraphOnto interoperates with an MPEG-7 Repository both for
            semantic entity reuse during multimedia content annotation and for semantic description storage. GraphOnto
            has been evaluated against Protégé and clearly outperforms it.

          <dc:description xml:lang="en">Summarization: The TV-Anytime standard describes structures of categories of
            digi-tal TV program metadata, as well as User Profile metadata for TV programs. We describe a natural
            language model for the users to interact with the TV-Anytime metadata and preview TV programs from their
            mobile devices. The language utilizes completely the TV-Anytime metadata specifications and it can
            accommodate future metadata extensions. The interaction model does not use clarification dialogues, but it
            uses the user profiles to rank the possible answers in case of ambiguities, as well as TV-Anytime Metadata
            information and on-tologies with information concerning digital TV. We describe an implementa-tion of the
            language that runs on a PDA and a mobile phone and manages the metadata on a remote TV-Anytime compatible TV
            set.

          <dc:description xml:lang="en">Summarization: In this paper, we describe a framework that we have developed for
            the support of ontology-based semantic indexing and retrieval of audiovisual content following the MPEG-7
            and TV-Anytime standard specifications for metadata descriptions. Our work aims to provide a methodology to
            enhance the retrieval effectiveness of audiovisual content, while maintaining compatibility with the
            international multimedia standards.
            In our framework, domain-specific ontologies guide the definition of both the application-specific metadata
            and the instance-description metadata that describe the contents of audiovisual programs and/or their
            segments. The ontologies are also used in order to provide compatible descriptions in both audiovisual
            content standards (MPEG-7 and TV-Anytime) for the same content. This approach allows indexing compatibility
            and interoperability of TV-Anytime and digital library applications.
            We describe the design and implementation of a system supporting this framework. The components of the
            system include a segmentation tool for segmenting audiovisual information, which also provides
            ontology-based semantic indexing capabilities, and an appropriate API for semantic query support. An
            application testbed for the domain of soccer games has been developed on top of this system. An ontology for
            soccer games has been defined and used for indexing and retrieval of soccer games that have been stored in
            the system database.
            The methodology we developed opens up a wide opportunity for the creation of MPEG-7 and TV-Anytime services
            offering structured domain-specific ontologies that can be integrated to these standards for enhancing
            audiovisual content retrieval performance.

          <dc:description xml:lang="en">Summarization: The problem of optimally placing data on disks (ODP) to maximize
            disk-access performance has long been recognized as important. Solutions to this problem have been reported
            for some widely available disk technologies, such as magnetic CAV and optical CLV disks. However, important
            new technologies such as multizoned magnetic disks, have been recently introduced. For such technologies no
            formal solution to the ODP problem has been reported. In this paper, we first identify the fundamental
            characteristics of disk-device technologies which influence the solution to the ODP problem. We develop a
            comprehensive solution to the problem that covers all currently available disk technologies. We show how our
            comprehensive solution can be reduced to the solutions for existing disk technologies, contributing thus a
            solution to the ODP problem for multizoned disks. Our analytical solution has been validated through
            simulations and through its reduction to the known solutions for particular disks

          <dc:description xml:lang="en">Summarization: Many current relational database systems use some form of
            histograms to approximate the frequency distribution of values in the attributes of relations and on this
            basis estimate query result sizes and access plan costs. The errors that exist in the histogram
            approximations directly or transitively affect many estimates derived by the database system. We identify
            the class of serial histograms and its subclass of end-btased histograms; the latter is of particular
            interest because such histograms are used in several database systems. We concentrate on equality join
            queries without function symbols where each relation is joined on the same attribute(s) for all joins in
            which it participates. Join queries of this restricted type are called t-cllque queries. We show that the
            optimal histogram for reducing the worst-case error in the result size of such a query is always serial. For
            queries with one join and no function symbols (all of which are vacuously t-clique queries), we present
            results on finding the optimal serial histogram and the optimal end-biased histogram based on the query
            characteristics and the frequency distributions of values in the join attributes of the query relations.
            Finally, we prove that for t-clique queries with a very large number of joins, h~gh-bzased h zstograms
            (which form a subclass of end-biased histograms) are always optimal. To construct a histogram for the join
            attribute(s) of a relation, the values in the attribute(s) must first be sorted based on their frequency and
            then assigned into buckets according to the optimality results above.

          <dc:description xml:lang="en">Summarization: This paper establishes some fundamental principles for the
            retrieval and storage of delay-sensitive multimedia data. Delay-sensitive data include digital audio,
            animations, and video. Retrieval of these data types from secondary storage has to satisfy certain time
            constraints in order to be acceptable to the user. The presentation is based on digital audio in order to
            provide intuition to the reader, although the results are applicable to all delay-sensitive data. A
            theoretical framework is developed for the real-time requirements of digital audio playback. We show how to
            describe these requirements in terms of the consumption rate of the audio data and the nature of the
            data-retrieval rate from secondary storage. Making use of this framework, bounds are derived for buffer
            space requirements for certain common retrieval scenarios. Storage placement strategies for multichannel
            synchronized data are then categorized and examined. The results presented in this paper are basic to any
            playback of delay-sensitive data and should assist the multimedia system designer in estimating hardware
            requirements and in evaluating possible design choices.

          <dc:description xml:lang="en">Summarization: Traditional file organizations for records may also be
            appropriate for the storage and retrieval of objects. Since objects frequently involve diverse data types
            (such as text, compressed images, graphics, etc.) as well as composite structures, they may have a largely
            variable length. In this paper, we assume that in the case of composite objects their components are
            clustered together and that object file organizations have overflows. The blocks of the main file are
            grouped so that they share a common number of overflow blocks. For this class of file organizations we
            present and analyze the performance of three different overflow searching algorithms. We show that the third
            algorithm gives very significant performance advantages under certain circumstances.

          <dc:description xml:lang="en">Summarization: In this paper we present COLearn platform which can be seen as a
            shell, easily integrated on top of existing open learning infrastructures (such as LMSs and OER
            repositories) to enrich their capabilities by offering functionality to design rich learning activities and
            learning workflows. COLearn run-time environment is used to enact these activities and workflows. This way,
            COLearn leverages the power of the underlying infrastructures, provides structure to the groups of learners
            that participate in learning workflows, dynamically adapts the workflows during their enactment, monitors
            their evolution to facilitate assessment and provides feedback to the learners. COLearn employs an intuitive
            graphical representation exploiting the BPMN standard. As an internal representation and interoperability
            model it uses IMS LD thus offering effective sharing and remixing to realize the vision of open educational
            practices. This is an important aspect as it makes explicit the, otherwise tacit knowledge pertaining to the
            design of learning experiences.

          <dc:description xml:lang="en">Summarization: Educators are facing the challenge to use the learning potential
            of games from several complementary objectives. Above all, they need to develop their own competencies and
            critical thinking on games. The overarching framework for a fruitful answer to this challenge could be
            structured around a particular type of literacy, the so-called gaming literacy. This new type of literacy
            seeks to provide a firm ground for cultivating a new type of thinking about the world that is more close to
            the children's way of thinking: “What does the world look like from the point of view of gaming?” To enable
            educators effectively move towards this direction, it is important to formalize the professional knowledge
            and skills they need to develop, offer new learning opportunities for them (either pre-service or
            in-service) and build communities of practice within which they could exchange their experiences and
            continue their professional development. We present our work towards this direction, the underlying learning
            framework, its initial conception, the first pilot implementation and directions of further developments
            focusing on mobile games.

          <dc:description xml:lang="en">Summarization: Computer Supported Collaborative Learning hasbecome an important
            part of e-learning providing interactivityand accessibility to learning resources either synchronouslyor
            asynchronously among users. In order to develop an elearning environment that supports collaborative
            learningone should cope with learning content, communication andcollaboration facilities, technological
            infrastructure, and runtime execution (i.e. learning process). Collaboration scripts areemployed to specify
            the components of the learning processincluding collaboration and interaction patterns within groupsof
            participants. In this paper we present a Computer SupportedCollaborative Learning platform which includes a
            collaborationscript authoring tool based on the Business Process ModelingNotation as the model for the
            graphical representation of scripts.Collaboration scripts are parsed and transformed to IMSLearning Design
            Level C learning flows. The second importantcomponent of the platform is the run time environment whichis
            based on the Copper Core Engine that executes the IMSLearning Design learning flows and a Message
            OrientedMiddleware which is built over the Extensible Messagingand Presence Protocol. This middleware layer
            enables groupmanagement and social interaction among participants. Theplatform integrates external learning
            tools by implementingthe IMS Learning Tool Interoperability specification. The IMSLearning Tool
            Interoperability specification is used to enable thedynamic integration of external tools through services.

          <dc:description xml:lang="en">Summarization: An experimental mass transfer correlation was developed for
            trichloroethylene (TCE) pools dissolving in watersaturated
            porous media. A three-dimensional, bench-scale model aquifer previously designed by Chrysikopoulos et al.
            (Water Resour. Res. 36(7) (2000) 1687) was employed for collection of the experimental dissolution data. The
            unique
            aspect of the model aquifer design is the formation of a well-defined, circular TCE pool at the bottom of
            the model
            aquifer. Steady-state dissolved TCE concentrations at specific downstream locations within the aquifer were
            collected
            for each of the seven interstitial velocities considered in this study. For each interstitial velocity, a
            corresponding time
            invariant overall mass transfer coefficient was determined by fitting the experimental data to an analytical
            solution
            applicable to nonaqueous phase liquid (NAPL) pools (Water Resour. Res. 31(4) (1995) 1137). Subsequently, a
            correlation relating the time invariant overall Sherwood number to appropriate overall Peclet numbers was
            developed.
            Relatively good agreement between the newly developed correlation and experimental data was observed. r 2002

            conservative tracer in a water saturated column packed with
            glass beads was investigated. It was observed from the
            experimental data that the addition of acoustic waves, in the
            frequency range between 60 to 245 Hz, to a steady
            background pressure gradient, enhances solute transport
            compared to the base case consisting of only a background
            pressure gradient. Furthermore, it was found that the effective
            velocity of the solute is approximately inversely proportional
            to the frequency of the acoustic wave.

          <dc:description xml:lang="en">Summarization: We conducted column-scale experiments to observe the effect of
            transport velocity
            and colloid size on early breakthrough of free moving colloids, to relate previous
            observations at the pore scale to a larger scale. The colloids used in these experiments
            were bacteriophage MS2 (0.025 mm), and 0.05- and 3-mm spherical polystyrene beads, and
            were compared with a conservative nonsorbing tracer (KCl). The results show that early
            breakthrough of colloids increases with colloid size and water velocity, compared with the
            tracer. These results are in line with our previous observations at the pore scale that
            indicated that larger colloids are restricted by the size exclusion effect from sampling all
            paths, and therefore they tend to disperse less and move in the faster streamlines, if they
            are not filtered out. The measured macroscopic dispersion coefficient decreases with
            colloid size due to the preferential flow paths, as observed at the pore scale. Dispersivity,
            typically considered only a property of the medium, is in this case also a function of
            colloid size, in particular at low Peclet numbers due to the size exclusion effect. Other
            parameters for colloid transport, such as collector efficiency and colloid filtration rates,
            were also estimated from the experimental breakthrough curve using a numerical fitting
            routine. In general, we found that the estimated filtration parameters follow the clean bed
            filtration model, although with a lower filtration efficiency overall.

          <dc:description xml:lang="en">Summarization: A closed-form analytical small-perturbation (or first-order)
            solution to the one-dimensional advection-dispersion equation with spatially variable retardation factor is
            derived to investigate the transport of sorbing but otherwise nonreacting solutes in hydraulically
            homogeneous but geochemically heterogeneous porous formations. The solution is developed for a third- or
            flux-type inlet boundary condition, which is applicable when considering resident (volume-averaged) solute
            concentrations, and a semi-infinite porous medium. For mathematical simplicity it is hypothesized that the
            sorption processes are based on linear equilibrium isotherms and that the local chemical equilibrium
            assumption is valid. The results from several simulations, compared with predictions based on the classical
            advection-dispersion equation with constant coefficients, indicate that at early times, spatially variable
            retardation affects the transport behavior of sorbing solutes. The zeroth moments corresponding to constant
            and variable retardation are not necessarily equal. The impact of spatially variable retardation increases
            with increasing Péclet number.

          <dc:description xml:lang="en">Summarization: A solute transport model incorporating well-to-well recirculation
            was developed to facilitate the interpretation of pilot-scale field experiments conducted for the evaluation
            of a test zone chosen for in situ restoration studies of contaminated aquifers, where flow was induced by
            recirculation of the extracted fluid. A semianalytical and an approximate analytical solution were derived
            to the one-dimensional advection-dispersion equation for a semi-infinite medium under local equilibrium
            conditions, with a flux-type inlet boundary condition accounting for solute recirculation between the
            extraction-injection well pair. Solutions were obtained by taking Laplace transforms to the equations with
            respect to time and space. The semianalytical solution is presented in Laplace domain and requires numerical
            inversion, while the approximate analytical solution is given in terms of a series of simple nested
            convolution integrals which are easily determined by numerical integration techniques. The applicability of
            the well-to-well recirculation model is limited to field situations where the actual flow field is one
            dimensional or where an induced flow field is obtained such that the streamlines in the neighborhood of the
            monitoring wells are nearly parallel. However, the model is fully applicable to studies of solute transport
            through packed columns with recirculation under controlled laboratory conditions.

          <dc:description xml:lang="en">Summarization: Closed form analytical solutions are derived for
            three-dimensional transient contaminant transport resulting from dissolution of single-component nonaqueous
            phase liquid pools in saturated porous media. The solutions are suitable for homogeneous porous media with
            unidirectional interstitial velocity. The dissolved solute may undergo first-order decay or may sorb under
            local equilibrium conditions. The solutions are obtained for rectangular and elliptic as well as circular
            source geometries, assuming that the dissolution process is mass transfer limited, by applying Laplace and
            Fourier transforms. Although the solutions contain integral expressions, these integrals are easily
            evaluated numerically. These solutions are useful for verifying the accuracy of numerical solutions to more
            comprehensive models and for design and interpretation of experiments in laboratory-packed beds and possibly
            some field studies. The results of several simulations indicate that for short downstream distances,
            predictions of contaminant concentrations are sensitive to the source structure and orientation with respect
            to the direction of interstitial flow .

            introduced by artificial
            groundwater recharge at the Nardo` fractured aquifer in the Salento area, Italy. Wastewater
            effluents from a municipal treatment plant with known pathogen concentrations were
            injected into a sinkhole and the migration of pathogens in the fractured aquifer was
            monitored at six sampling wells. The fate of pathogens was quantified by a mathematical
            model describing colloid transport in a set of three-dimensional, parallel fractures with
            spatially variable aperture. The number of parallel fractures and their average fracture
            aperture were determined from appropriate field pumping and tracer tests. The aperture
            spatial distribution was described by an experimental semivariogram developed from
            available field data obtained from two tracer tests and 34 pumping tests. The experimental
            results suggest that for the municipal wastewater injected into the Nardo` aquifer the
            required most conservative set back distance for drinking wells should be over 8000 m.

          <dc:description xml:lang="en">Summarization: The main objective of this study was to evaluate the combined
            effects of grain size and pore
            water velocity on the transport in water saturated porous media of three waterborne fecal indicator
            organisms (Escherichia coli, MS2, and ΦX174) in laboratory-scale columns packed with
            clean quartz sand. Three different grain sizes and three pore water velocities were examined
            and the attachment behavior of Escherichia coli, MS2, and ΦX174 onto quartz sand was evaluated.
            The mass recoveries of the biocolloids examined were shown to be highest for Escherichia
            coli and lowest for MS2. However, no obvious relationships between mass recoveries and
            water velocity or grain size could be established from the experimental results. The observed
            mean dispersivity values for each sand grain size were smaller for bacteria than coliphages, but
            higher for MS2 than ΦX174. The single collector removal and collision efficiencies were quantified
            using the classical colloid filtration theory. Furthermore, theoretical collision efficiencies
            were estimated only for E. coli by the Interaction-Force-Boundary-Layer, and Maxwell approximations.
            Better agreement between the experimental and Maxwell theoretical collision efficiencies
            were observed.

          <dc:description xml:lang="en">Summarization: This study is focused on Pseudomonas putida bacteria transport in
            porous media in the
            presence of suspended kaolinite clay particles. Experiments were performed with bacteria
            and kaolinite particles separately to determine their individual transport characteristics in
            water-saturated columns packed with glass beads. The results indicated that the mass
            recovery of bacteria and clay particles decreased as the pore water velocity decreased.
            Batch experiments were carried out to investigate the attachment of Pseudomonas putida
            onto kaolinite particles. The attachment process was adequately described by a Langmuir
            isotherm. Finally, bacteria and kaolinite particles were injected simultaneously into a
            packed column in order to investigate their cotransport behavior. The experimental data
            suggested that the presence of clay particles significantly inhibited the transport of bacteria
            in water-saturated porous media. The observed reduction of Pseudomonas putida recovery
            in the column outflow was attributed to bacteria attachment onto kaolinite particles, which
            were retained onto the solid matrix of the column. A mathematical model was developed to
            describe the transport of bacteria in the presence of suspended clay particles in onedimensional
            water-saturated porous media. Model simulations were in good agreement with
            the experimental results.

          <dc:description xml:lang="en">This study employed for the first time carbohydrate-enriched
            dry and living biomass of A. platensis as biosorbent for copper or
            nickel ions. The results show that the various biomass compositions
            of A. platensis obtained from cultivation under different phosphorus
            concentrations had a diverse effect on Cu2+ and Ni2+
            biosorption capacity. The experiments with dry biomass show that
            the accumulation of carbohydrates slightly improved the biosorption
            capacity for nickel, but significantly improved the biosorption
            capacity for copper. In contrast, the experiments with living biomass
            show that the accumulation of carbohydrates decreased the
            biosorption capacity for both metals. A. platensis showed greater
            biosorption capacity for Ni2+ than for Cu2+. For all biomass types
            investigated, the pseudo-second order kinetics model fitted better
            the experimental data, but underestimated slightly the early time
            data (first 15 min). It was observed that the intra-particle diffusion
            was not a limited process, and that intra-particle diffusion model
            described well the experimental data for the first 15 min. Also, it
            was observed that the Freundlich model represents better the
            biosorption onto living biomass due to the presence of possible
            bioaccumulation, whereas, the Langmuir model fits better the
            experimental data with dry biomass. The results show that the
            main sorption mechanisms involved were ion exchange and
            complexation. In general, the carbohydrate-enriched biomass contributed
            to a weak ion-exchange sorption.

          <dc:description xml:lang="en">Summarization: This study is focused on copper and nickel biosorption onto
            Arthrospira platensis biomass of different biochemical
            compositions. Four types of A. platensis were employed, namely: (1) typical dry biomass (TDB),
            (2) carbohydrate-enriched dry biomass (CDB), (3) typical living biomass (TLB), and (4) carbohydrateenriched
            living biomass (CLB). The CDB was produced using a cultivation mode where phosphorus was
            the limiting nutrient. The biosorption of both metals investigated was shown to be very fast. Most of
            the metal sorption capacity of the biomass was filled within 15–30 min, and equilibrium was achieved
            within 30–60 min. The cultivation conditions (nutrient repletion or depletion) did not affect the pattern
            of copper and nickel biosorption kinetics. The capacity for copper ions biosorption was significantly
            positively
            affected by the accumulation of carbohydrates in the dry biomass, but was negatively affected by
            the accumulation of carbohydrates in the living biomass. For nickel ions, the alteration of biomass had a
            little but positive effect on the dry biomass, and a greater negative effect (about 30% lower biosorption
            capacity) on the living biomass. Living biomass exhibited a higher biosorption capacity than dry biomass,
            for both metals. The biosorption of copper and nickel onto A. platensis biomass occurred mainly due to the
            mechanisms of ion exchange and complexation, and less to physical adsorption.

          <dc:description xml:lang="en">Summarization: The role of gravitational force on colloid
            transport in water-saturated columns packed with glass beads
            was investigated. Transport experiments were performed with
            colloids (clays: kaolinite KGa-1b, montmorillonite STx-1b).
            The packed columns were placed in various orientations
            (horizontal, vertical, and diagonal) and a steady flow rate of Q
            = 1.5 mL/min was applied in both up-flow and down-flow
            modes. All experiments were conducted under electrostatically
            unfavorable conditions. The experimental data were fitted with a newly developed, analytical,
            one-dimensional, colloid transport
            model. The effect of gravity is incorporated in the mathematical model by combining the interstitial
            velocity (advection) with the
            settling velocity (gravity effect). The results revealed that flow direction influences colloid transport in
            porous media. The rate of
            particle deposition was shown to be greater for up-flow than for down-flow direction, suggesting that
            gravity was a significant
            driving force for colloid deposition

          <dc:description xml:lang="en">Summarization: The effects of acoustic wave propagation on the transport of
            colloids in saturated porous media were investigated by injecting Uranine (conservative
            tracer) as well as blue and red polystyrene microspheres (colloids of different diameters; 0.10 and 0.028
            μm, respectively) into a column
            packed with glass beads. Experiments were conducted by maintaining the acoustic pressure at the influent at
            23.0 kPa with acoustic frequencies
            ranging from 30 to 150 Hz. The experimental results suggested that colloid size did not affect the forward
            and reverse attachment rate coefficients.
            The acoustic pressure caused an increase in the effective interstitial velocity at all frequencies for the
            conservative tracer and colloids of both sizes,
            with maximum increase at 30 Hz. Furthermore, acoustics enhanced the dispersion process at all frequencies,
            with a maximum at 30 Hz.

            concentration determination of conservative
            tracers and pollutants in a two-dimensional glass pore network model. The method presented is
            an extension to the work by Huang et al. [1], and Thomas and Chysikopoulos [2]. The method consists of
            fabricating the glass pore network model using a photolithography technique, conducting flowthrough
            contaminant transport experiments, taking digital photographs at various times of the two-dimensional
            pore network under ultraviolet or visible light source, and determining the spatially-distributed pollutant
            concentrations by measuring the color intensity in the photographs with comparative image
            analysis. Therefore, the method is limited to fluorescent or colored pollutants and tracers. The method
            was successfully employed to in situ concentration determination of uranine and red color tracers.

          <dc:description xml:lang="en">Summarization: Taylor-Aris dispersion theory, as generalized by Brenner, is
            employed to investigate the macroscopic behavior of sorbing solute transport in a three-dimensional,
            hydraulically homogeneous porous medium under steady, unidirectional flow. The porous medium is considered
            to possess spatially periodic geochemical characteristics in all three directions, where the spatial periods
            define a rectangular parallelepiped or a unit-element. The spatially-variable geochemical parameters of the
            solid matrix are incorporated into the transport equation by a spatially-periodic distribution coefficient
            and consequently a spatially-periodic retardation factor. Expressions for the effective or large-time
            coefficients governing the macroscopic solute transport are derived for solute sorbing according to a linear
            equilibrium isotherm as well as for the case of a first-order kinetic sorption relationship. The results
            indicate that for the case of a chemical equilibrium sorption isotherm the longitudinal macrodispersion
            incorporates a second term that accounts for the eflect of averaging the distribution coefficient over the
            volume of a unit element. Furthermore, for the case of a kinetic sorption relation, the longitudinal
            macrodispersion expression includes a third term that accounts for the effect of the first-order sorption
            rate. Therefore, increased solute spreading is expected if the local chemical equilibrium assumption is not
            valid. The derived expressions of the apparent parameters governing the macroscopic solute transport under
            local equilibrium conditions agreed reasonably with the results of numerical computations using particle
            tracking techniques.

          <dc:description xml:lang="en">Summarization: This study is focused on the transport of Pseudomonas (P.) putida
            bacterial cells
            in a 3-D model aquifer. The pilot-scale aquifer consisted of a rectangular glass tank with
            internal dimensions: 120 cm length, 48 cm width, and 50 cm height, carefully packed with
            well-characterized quartz sand. The P. putida decay was adequately represented by a firstorder
            model. Transport experiments with a conservative tracer and P. putida were conducted
            to characterize the aquifer and to investigate the bacterial behavior during transport in water
            saturated porous media. A 3-D, finite-difference numerical model for bacterial transport in
            saturated, homogeneous porous media was developed and was used to successfully fit the
            experimental data. Furthermore, theoretical interaction energy calculations suggested that
            the extended-DLVO theory seems to predict bacteria attachment onto the aquifer sand better
            than the classical DLVO theory.

          <dc:description xml:lang="en">Summarization: This study examines the cotransport of clay colloids and viruses
            in laboratory packed columns. Bacteriophages
            MS2 and X174 were used as model viruses, kaolinite (kGa-1b) and montmorillonite (STx-1b)
            as model clay colloids, and glass beads as model packing material. The combined and synergistic effects
            of clay colloids and pore water velocity on virus transport and retention in porous media were examined
            at three pore water velocities (0.38, 0.74, and 1.21 cm/min). The results indicated that the mass recovery
            of viruses and clay colloids decreased as the pore water velocity decreased; whereas, for the cotransport
            experiments no clear trend was observed. Temporal moments of the breakthrough concentrations suggested
            that the presence of clays significantly influenced virus transport and irreversible deposition onto
            glass beads. Mass recovery values for both viruses, calculated based on total virus concentration in the
            effluent, were reduced compared to those in the absence of clays. The transport of both suspended and
            attached onto suspended clay-particles viruses was retarded, compared to the tracer, only at the highest
            pore water velocity. Moreover both clay colloids were shown to hinder virus transport at the highest pore
            water velocity.

          <dc:description xml:lang="en">Summarization: A model is developed to describe the transport of colloids in a
            saturated fracture with a spatially variable aperture, accounting for colloid deposition onto fracture
            surfaces under various physicochemical conditions. The fracture plane is partitioned into unit elements with
            different apertures generated stochastically from a log-normal distribution. The model also accounts for
            colloid size exclusion from fracture elements with small apertures. Both equilibrium and kinetic colloid
            deposition onto fracture surfaces are investigated. Colloid surface exclusion is incorporated in the
            dynamics of kinetic deposition. The impact of deposited colloids on further colloid deposition is described
            by either a linear or a non-linear blocking function. The resulting system of governing partial differential
            equations is solved numerically using the fully implicit finite difference method. Model simulations
            illustrate the presence of preferential colloid transport in the fracture plane. It is shown that size
            exclusion increases the dispersion of colloids and leads to earlier breakthrough, especially for large-size
            particles. Furthermore, it is demonstrated that surface exclusion enhances colloid transport, and the
            assumption of clean-bed media may underestimate liquid-phase colloid concentrations.

          <dc:description xml:lang="en">Summarization: A three-dimensional physical aquifer model was used to study the
            dissolution of a
            dense nonaqueous phase liquid (DNAPL) pool. The model aquifer comprised a packing of
            homogeneous, medium-sized sand and conveyed steady, unidirectional flow.
            Tetrachloroethene (PCE) pools were introduced within model aquifers atop glass- and
            clay-lined aquifer bottoms. Transient breakthrough at an interstitial velocity of 7.2 cm/h,
            and three-dimensional steady state concentration distributions at velocities ranging from
            0.4 to 7.2 cm/h were monitored over periods of 59 and 71 days for the glass- and claybottom
            experiments, respectively. Pool-averaged mass transfer coefficients were obtained
            from the observations via a single-parameter fit using an analytical model formulated with
            a second type boundary condition to describe pool dissolution [Chrysikopoulos, 1995].
            Other model parameters (interstitial velocity, longitudinal and transverse dispersion
            coefficients, and pool geometry) were estimated independently. Simulated and observed
            dissolution behavior agreed well, except for locations relatively close to the pool or the
            glass-bottom plate. Estimated mass transfer coefficients ranged from 0.15 to 0.22 cm/h,
            increasing weakly with velocity toward a limiting value. Pool mass depletions of 31 and
            43% for the glass- and clay-bottom experiments failed to produce observable changes in
            the plumes and suggested that changes in pool interfacial area over the period of the
            experiment were negligible. Dimensionless mass transfer behavior was quantified using a
            modified Sherwood number (Sh*). Observed Sh* values were found to be about 2–3
            times greater than values predicted by an existing theoretical mass transfer correlation,
            and 3–4 times greater than those estimated previously for an ideally configured
            trichloroethene (TCE) pool (circular and smooth). It appeared that the analytical model’s
            failure to account for pore-scale pool-water interfacial characteristics and larger scale pool
            shape irregularities biased the Sh* estimates toward greater values

          <dc:description xml:lang="en">Summarization: Expressions for the macroscopic velocity vector and dispersion
            tensor for sorbing solute transport in heterogeneous porous formations whose hydrogeologic properties are
            repeated at intervals were derived via Taylor-Aris-Brenner moment analysis. An idealized three-dimensional
            porous formation of infinite domain with spatially periodic retardation factor, velocity field, and
            microdispersion coefficients in all three directions was considered. Sorption was assumed to be governed by
            a linear equilibrium isotherm under local chemical equilibrium conditions. The analytical expressions
            presented are based on a perturbation method where all of the spatially periodic parameters employed were
            assumed to have ``small'' fluctuations. It was shown that the effective velocity vector is given by the
            volume-averaged interstitial velocity vector divided by the volume-averaged retardation factor, and the
            effective dispersion dyadic (second-order tensor) is given by the volume-averaged microdispersion dyadic
            divided by the volume-averaged dimensionless retardation factor plus a dyadic expressing the increase in
            solute spreading caused by the spatial variability of the parameters.

          <dc:description xml:lang="en">Summarization: A field-scale experiment was conducted at a research site using
            bacterial viruses
            (bacteriophage) MS2 and PRD1 as surrogates for human viruses, bromide as a
            conservative tracer, and tertiary-treated municipal wastewater (recycled water) to
            investigate the fate and transport of viruses during artificial recharge. Observed virus
            concentrations were fitted using a mathematical model that simulates virus transport in
            one-dimensional, homogeneous, water-saturated porous media accounting for virus
            sorption (or filtration), virus inactivation, and time-dependent source concentration. The
            fitted time-dependent clogging rate constants were used to estimate the collision
            efficiencies for bacteriophage MS2 and PRD1 during vertical fully saturated flow.
            Furthermore, the corresponding time-dependent collision efficiencies for both
            bacteriophage asymptotically reached similar values at the various sampling locations.
            These results can be used to develop an optimal management scenario to maximize the
            amount of recycled water that can be applied to the spreading grounds while still
            maintaining favorable attachment conditions for virus removal.

          <dc:description xml:lang="en">Summarization: A conceptual mathematical model was developed to describe the
            simultaneous transport (cotransport) of
            viruses and colloids in three-dimensional, water saturated, homogeneous porous media with uniform
            flow. The model accounts for the migration of individual virus and colloid particles as well as viruses
            attached onto colloids. Viruses can be suspended in the aqueous phase, attached onto suspended colloids
            and the solid matrix, and attached onto colloids previously attached on the solid matrix. Colloids can be
            suspended in the aqueous phase or attached on the solid matrix. Viruses in all four phases (suspended in
            the aqueous phase, attached onto suspended colloid particles, attached on the solid matrix, and attached
            onto colloids previously attached on the solid matrix) may undergo inactivation with different inactivation
            coefficients. The governing coupled partial differential equations were solved numerically using
            finite difference methods, which were implemented explicitly or implicitly so that both stability and
            speed factors were satisfied

          <dc:description xml:lang="en">Summarization: Polycyclic aromatic hydrocarbons (PAHs) are persistent organic
            compounds, which have
            been reported in the literature to efficiently degrade at low (e.g. 20 kHz) and moderate (e.g.
            506 kHz) ultrasound frequencies. The present study focuses on degradation of naphthalene,
            phenanthrene, and pyrene by ultrasound at three different relatively high frequencies
            (i.e. 582, 862, and 1142 kHz). The experimental results indicate that for all three frequencies
            and power inputs 133 W phenanthrene degrades to concentrations lower than our
            experimental detection limit (&lt;1 mg/L). Phenanthrene degrades significantly faster at
            582 kHz than at 862 and 1142 kHz. For all three frequencies, the degradation rates per unit
            mass are similar for naphthalene and phenanthrene and lower for pyrene. Furthermore,
            naphthalene degradation requires less energy than phenanthrene, which requires less
            energy than pyrene under the same conditions. No hexane-extractable metabolites were
            identified in the solutions.

          <dc:description xml:lang="en">Summarization: In this work, various TiO2 NP suspensions were prepared using
            different preparation techniques.
            Rutile-anatase and anatase TiO2 NPs were used for the preparation of aquatic NP suspensions at
            various concentrations. Measurements of particles size and zeta potential were performed in order
            to investigate the effect of sonication and aging on nanoparticle agglomerates. Finally, transport
            experiments of TiO2 NP solutions in packed columns were performed for varying TiO2
            concentrations. The concentration and size of the NPs were measured at the outlet of the column. It
            was observed that a substantial percentage of the NPs injected into the experimental column were
            retained in the column packing.

            visible light (VL) on virus inactivation
            were investigated. The bacteriophages X174 and MS2 were used as model viruses. The experiments
            were performed at room temperature at three different, relatively high US frequencies (i.e., 582, 862, and
            1142 kHz) with and without the use of VL, and different initial virus concentrations. The two bacteriophages
            were diluted in phosphate-buffered saline solution to a titer of 103–104 pfu/mL. The experimental
            virus inactivation data were satisfactorily represented by a simple first-order kinetic expression. Virus
            inactivation was faster at the lower frequencies (582 and 862 kHz). Furthermore, it was observed that
            MS2 was inactivated faster than X174. The simultaneous use of US and VL was found to be more effective
            than US alone for MS2 inactivation, indicating the existence of a synergistic effect

          <dc:description xml:lang="en">Summarization: This study is focused on the transport of Pseudomonas (P.) putida
            bacterial cells
            in a 3-D model aquifer. The pilot-scale aquifer consisted of a rectangular glass tank with
            internal dimensions: 120 cm length, 48 cm width, and 50 cm height, carefully packed with
            well-characterized quartz sand. The P. putida decay was adequately represented by a firstorder
            model. Transport experiments with a conservative tracer and P. putida were conducted
            to characterize the aquifer and to investigate the bacterial behavior during transport in water
            saturated porous media. A 3-D, finite-difference numerical model for bacterial transport in
            saturated, homogeneous porous media was developed and was used to successfully fit the
            experimental data. Furthermore, theoretical interaction energy calculations suggested that
            the extended-DLVO theory seems to predict bacteria attachment onto the aquifer sand better
            than the classical DLVO theory.

          <dc:description xml:lang="en">Summarization: Virus transport in groundwater is controlled mainly by attachment
            onto the solid matrix and
            inactivation. Therefore, understanding how the various parameters affect virus attachment can lead to
            improved virus transport predictions and better health risk evaluations. This study is focused on the
            attachment of viruses onto quartz sand under batch experimental conditions. The bacteriophages
            FX174 and MS2 were used as model viruses. Three different sand grain sizes were employed for the
            static and dynamic experiments. The batch sorption experiments were performed under static
            conditions at 4 8C and 20 8C and dynamic conditions at 4 8C. The experimental data were adequately
            described by the Freundlich isotherm. It was shown that temperature significantly affects virus
            attachment under static conditions. The attachment of both MS2 and FX174 onto quartz sand was
            greater at 20 8C than 4 8C. Higher virus attachment was observed under dynamic than static conditions,
            and in all cases, the affinity of MS2 for quartz sand was greater than that of FX174. Furthermore, in most
            of the cases considered, bacteriophage attachment was shown to decrease with increasing quartz sand
            size.

          <dc:description xml:lang="en">Summarization: A three-dimensional model for contaminant
            transport resulting from the dissolution of multicomponent
            nonaqueous phase liquid (NAPL) pools in threedimensional
            saturated subsurface formations is developed.
            The solution is obtained numerically by a finite-difference
            scheme, and it is suitable for homogeneous porous media
            with unidirectional interstitial velocity. Each dissolved
            component may undergo first-order decay and may sorb
            under local equilibrium conditions. It is also assumed that
            the dissolution process is mass transfer limited. The nonaqueous
            phase activity coefficients of the NAPL pool
            components are evaluated at each time step. The model
            behavior is illustrated through a synthetic example with
            a NAPL pool consisting of a mixture of TCA (1,1,2-
            trichloroethane) and TCE (trichloroethylene). The numerical
            solution presented in this work is in good agreement
            with a recently developed analytical solution for the special
            case of a single component NAPL pool. The results
            indicate the importance of accounting for the necessary
            changes in the organic phase activity which significantly
            affects the equilibrium aqueous solubility

          <dc:description xml:lang="en">Summarization: Correlations describing the rate of interface mass transfer from
            singlecomponent
            nonaqueous phase liquid (NAPL) pools in saturated subsurface formations are
            developed. A three-dimensional contaminant transport model is employed to obtain
            overall mass transfer coefficients computed from concentration gradients at the NAPLwater
            interface. The model assumes that the porous medium is homogeneous, the
            interstitial fluid velocity is steady, and the dissolved solute may sorb under local
            equilibrium conditions. Furthermore, it is assumed that the dissolved concentration along
            the NAPL-water interface is equal to the solubility concentration. Power law correlations
            relate the overall Sherwood number to the appropriate overall Peclet numbers. Both
            rectangular and elliptic/circular source geometries are considered. The proposed
            relationships are fitted to numerically determined mass transfer coefficients, and the
            correlation coefficients are determined by nonlinear least squares regression. Good
            agreement between predicted and available experimentally determined overall mass
            transfer coefficients is observed

          <dc:description xml:lang="en">Summarization: Mercury poses a severe threat to environment due to its toxicity,
            even at low concentrations. Biosorption
            is a promising, low cost, and environmentally friendly clean up technique. Malt spent rootlets (MSR), a
            brewery by-product, were used as sorbents for the removal of mercury from aquatic systems. The effect
            of the solution pH, contact time between sorbent, solid to liquid ratio, and initial mercury concentration
            on mercury removal were investigated experimentally. It was found that the optimum pH for the mercury
            sorption onto MSR was approximately 5. Sorption kinetic experiments revealed that mercury sorption
            is a relatively rapid process, where film diffusion and intra-particle diffusion play an important role.
            The kinetic data were successfully described by both the pseudo-second-order and Elovich models. The
            isotherm data were adequately fitted by the Langmuir model determining a monolayer capacity qmax
            equal to 50 mg/g and suggesting a functional group-limited sorption process. MSR were capable of
            removing significant amounts of mercury, mainly due to the carboxyl and phosphonate groups of their
            surfaces.

            nonaqueous phase liquids in
            water saturated porous media are investigated. Experiments of trichloroethylene (TCE)
            ganglia dissolution within a water saturated column, packed with glass beads, are
            conducted. Acoustic waves with pressure amplitudes ranging from 0 to 1625 Pa and
            frequencies ranging from 0 to 285 Hz are employed to the interstitial fluid at the inlet of
            the packed column. Effluent dissolved TCE concentrations are observed to increase up to
            120% in the presence of acoustic pressure waves compared to the case where TCE
            dissolution without acoustic waves is monitored. The observed effluent dissolved TCE
            concentration increase is attributed to enhanced mass flux at the TCE-water interface,
            caused by acoustic waves. Highest dissolution rates occur at discrete frequencies suggesting
            resonance effects or the presence of standing waves. Although acoustic waves
            enhance TCE dissolution, they dissipate almost exponentially with distance from the
            acoustic source

          <dc:description xml:lang="en">Summarization: Human adenoviruses (hAdVs) are pathogenic viruses responsible for
            public health problems worldwide. They
            have also been used as viral indicators in environmental systems. Coliphages (e.g., MS2, ΦX174) have also
            been studied as indicators of viral pollution in fecally contaminated water. Our objective was to evaluate
            the
            distribution of three viral fecal indicators (hAdVs, MS2, and ΦΧ174), between two different phyllosilicate
            clays
            (kaolinite and bentonite) and the aqueous phase. A series of static and dynamic experiments were conducted
            under two different temperatures (4, 25 °C) for a time period of seven days. HAdV adsorption was examined
            in DNase I reaction buffer (pH=7.6, and ionic strength (IS)=1.4 mM), whereas coliphage adsorption in
            phosphate
            buffered saline solution (pH=7, IS=2 mM). Moreover, the effect of IS on hAdV adsorption under static
            conditions was evaluated. The adsorption of hAdVwas assessed by real-time PCR and its infectivitywas tested
            by
            cultivation methods. The coliphages MS2 and ΦΧ174 were assayed by the double-layer overlay method. The
            experimental results have shown that coliphage adsorption onto both kaolinite and bentonite was higher for
            the dynamic than the static experiments; whereas hAdV adsorption was lower under dynamic conditions. The
            adsorption of hAdV increased with decreasing temperature, contrary to the results obtained for the
            coliphages.
            This study examines the combined effect of temperature, agitation, clay type, and IS on hAdV adsorption onto
            clays. The results provide useful new information on the effective removal of viral fecal indicators (MS2,
            ΦX174 and hAdV) from dilute aqueous solutions by adsorption onto kaolinite and bentonite

          <dc:description xml:lang="en">Summarization: This study aims to gain insights into the interaction of virus
            particles with clay colloids. Bacteriophages
            MS2 and X174 were used as model viruses and kaolinite (KGa-1b) and montmorillonite (STx-1b) as
            model colloids. The experimental data obtained from batch experiments of MS2 and X174 attachment
            onto KGa-1b and STx-1b suggested that virus attachment is adequately described by the Freundlich
            isotherm equation. Both MS2 and X174 were attached in greater amounts onto KGa-1b than STx-1b
            with MS2 having greater affinity than X174 for both clays. Furthermore, extended-DLVO interaction
            energy calculations explained that the attachment of viruses onto model clay colloids was primarily
            caused by hydrophobic interaction. The theoretical and experimental results of this study were found to
            be in good agreement with previous findings.

          <dc:description xml:lang="en">Summarization: The transport of variably sized colloids (polydisperse) in a
            fracture with
            uniform aperture is investigated by a particle-tracking model that treats colloids as
            discrete particles with unique transport properties while accounting for either matrix
            diffusion or irreversible colloid deposition. For the special case of a monodisperse colloid
            suspension the particle-tracking model is in perfect agreement with predictions based on
            an existing analytical solution. It is shown that lognormal colloid size distributions exhibit
            greater spreading than monodisperse suspensions. Increasing the fracture porosity of the
            solid matrix leads to higher matrix diffusion, which in turn delays particle breakthrough
            for both the monodisperse and variably sized colloid suspensions. The smallest particles of
            a distribution are more greatly affected by matrix diffusion whereas the largest particles
            are transported faster and further along a fracture. Both perfect sink and kinetic colloid
            deposition onto fracture surfaces are examined. Kinetic deposition accounts for colloid
            surface exclusion by either a linear or nonlinear blocking function. For both cases the
            smallest colloid particles tend to preferentially deposit onto the fracture wall. Both matrix
            diffusion and surface deposition tend to discretize colloid distributions according to
            particle size so that larger particles are least retarded and smaller particles are more
            slowly transported. Furthermore, it is shown that the rate of colloid deposition is inversely
            proportional to the fracture aperture.

            human enteric viruses from various wastewater discharges,
            sanitary landfills, septic tanks, agricultural practices, and
            artificial groundwater recharge. Coliphages have been widely
            used as surrogates of enteric viruses, because they share many
            fundamental properties and features.Although a large number
            of studies focusing on various factors (i.e. pore water solution
            chemistry, fluid velocity, moisture content, temperature, and
            grain size) that affect biocolloid (bacteria, viruses) transport
            have been published over the past two decades, little attention
            has been given toward human adenoviruses (hAdVs). The
            main objective of this study was to evaluate the effect of pore
            water velocity on hAdV transport in water saturated laboratory-
            scale columns packed with glass beads. The effects of
            pore water velocity on virus transport and retention in porous
            media was examined at three pore water velocities (0.39, 0.75,
            and 1.22 cm/min). The results indicated that all estimated
            averagemass recovery values forhAdVwere lower than those
            of coliphages, which were previously reported in the literature
            by others for experiments conducted under similar experimental
            conditions.

            controls virus fate and transport in the
            subsurface. In this study the inactivation of viruses in the presence of quartz sand was examined. The
            bacteriophages
            MS2 and X174 were used as model viruses. Experiments were performed at 4 ◦C and 20 ◦C,
            under constant controlled conditions, to investigate the effect of virus type, temperature, sand size, and
            initial virus concentration on virus inactivation. The experimental virus inactivation data were
            satisfactorily
            represented by a pseudo-first order expression with time-dependent rate coefficients. Furthermore,
            the results indicated that virus inactivation was substantially affected by the ambient temperature and
            initial virus concentration. The inactivation rate of MS2 was shown to be greater than that of X174.
            However, the greatest inactivation was observed for MS2 without the presence of sand, at 20 ◦C. Sand
            surfaces offered protection against inactivation especially under static conditions. However, no obvious
            relationship between sand particle size and virus inactivation could be established from the experimental
            data. Moreover, the inactivation rates were shown to increase with decreasing virus concentration

            plumes of neutral buoyancy within a fracture with uniform aperture. Various initial and boundary conditions

            colloid diameter
            enhances colloid spreading and increases the number of attached colloids when colloid–wall interactions are
            taken into account.
            Excellent agreement between available experimental data and the analytical solution for the case of an
            instantaneous release of
            monodisperse colloids in a natural fracture is observed.

            model is developed to characterize the spatial and temporal
            effects of advection, molecular diffusion, Taylor
            dispersion, fracture wall deposition, matrix diffusion,
            and co-transport processes on two discrete plumes
            (suspended monodisperse or polydisperse colloids and
            dissolved contaminants) flowing through a variable
            aperture fracture situated in a porous medium. Contaminants
            travel by advection and diffusion and may
            sorb onto fracture walls and colloid particles, as well as
            diffuse into and sorb onto the surrounding porous rock
            matrix. A kinetic isotherm describes contaminant sorption
            onto colloids and sorbed contaminants assume the
            unique transport properties of colloids. Sorption of the
            contaminants that have diffused into the matrix is governed
            by a first-order kinetic reaction. Colloids travel by
            advection and diffusion and may attach onto fracture
            walls; however, they do not penetrate the rock matrix. A
            probabilistic form of the Boltzmann law describes filtration
            of both colloids and contaminants on fracture
            walls. Ensemble-averaged breakthrough curves of many
            fracture realizations are used to compare arrival times of
            colloid and contaminant plumes at the fracture outlet.
            Results show that the presence of colloids enhances
            contaminant transport (decreased residence times) while
            matrix diffusion and sorption onto fracture walls retard
            the transport of contaminants. Model simulations with
            the polydisperse colloids show increased effects of cotransport
            processes.

          <dc:description xml:lang="en">Summarization: A conceptual mathematical model was developed to describe the
            simultaneous transport (cotransport) of
            viruses and colloids in three-dimensional, water saturated, homogeneous porous media with uniform
            flow. The model accounts for the migration of individual virus and colloid particles as well as viruses
            attached onto colloids. Viruses can be suspended in the aqueous phase, attached onto suspended colloids
            and the solid matrix, and attached onto colloids previously attached on the solid matrix. Colloids can be
            suspended in the aqueous phase or attached on the solid matrix. Viruses in all four phases (suspended in
            the aqueous phase, attached onto suspended colloid particles, attached on the solid matrix, and attached
            onto colloids previously attached on the solid matrix) may undergo inactivation with different inactivation
            coefficients. The governing coupled partial differential equations were solved numerically using
            finite difference methods, which were implemented explicitly or implicitly so that both stability and
            speed factors were satisfied. Furthermore, the experimental data collected by Syngouna and Chrysikopoulos
            [1] were satisfactorily fitted by the newly developed cotransport model.

          <dc:description xml:lang="en">Interpolation of parameters characterizing the geometry
            of channel beds is needed to support flow modeling
            at varying grid resolutions. Three methods of interpolating
            geometric parameters between survey stations
            were described including piece-wise linear interpolation,
            monotone piece-wise-cubic Hermitian interpolation,
            and universal kriging. The latter gives parameter estimates
            that minimize the mean square error of the interpolator
            and therefore is considered the most accurate
            method. Based on the application of these methods to
            a dataset describing cross-sectional properties at 283 stations,
            piece-wise linear interpolation gave parameter
            estimates that very closely track universal kriging estimates.
            Piece-wise-cubic interpolation, including monotone
            piece-wise-cubic Hermitian interpolation and
            cubic spline interpolation, gave parameter estimates that

          <dc:description xml:lang="en">Summarization: Channel geometry often is described by a set of longitudinally
            varying parameters measured at a set of survey stations. To support
            flow modeling at arbitrary resolution, three methods of parameter interpolation are described including
            piece-wise linear interpolation,
            monotone piece-wise-cubic Hermitian interpolation, and universal kriging. The latter gives parameter
            estimates that
            minimize the mean square error of the interpolator, and therefore can be used as a standard against which
            the accuracy of polynomial
            methods can be assessed. Based on the application of these methods to a dataset describing cross-sectional
            properties at 283
            stations, piece-wise linear interpolation gives parameter estimates that closely track universal kriging
            estimates and therefore this
            method is recommended for routine modeling purposes. Piece-wise-cubic interpolation gives parameter
            estimates that do not track
            as well. Differences between cubic and kriging estimates were found to be 2–10 times larger than differences
            between linear and kriging
            parameter estimates. In the context of one-dimensional flow modeling, the sensitivity of steady state water
            level predictions to
            the channel bed interpolator is comparable to a 5% change in the Manning coefficient.

          <dc:description xml:lang="en">Summarization: A two-dimensional numerical transport model is developed to
            determine the effect of aquifer anisotropy and heterogeneity
            on mass transfer from a dense nonaqueous phase liquid (DNAPL) pool. The appropriate steady state groundwater
            flow equation
            is solved implicitly whereas the equation describing the transport of a sorbing contaminant in a confined
            aquifer is solved
            by the alternating direction implicit method. Statistical anisotropy in the aquifer is introduced by
            two-dimensional, random
            log-normal hydraulic conductivity field realizations with different directional correlation lengths. Model
            simulations indicate
            that DNAPL pool dissolution is enhanced by increasing the mean log-transformed hydraulic conductivity,
            groundwater flow velocity,
            and/or anisotropy ratio. The variance of the log-transformed hydraulic conductivity distribution is shown to
            be inversely
            proportional to the average mass transfer coefficient.

          <dc:description xml:lang="en">Summarization: Bacteriophage MS2 and ΦX174 were used as surrogates for
            human viruses in order to investigate the interaction between
            viruses and clay particles. The selected phyllosilicate clays
            were kaolinite and bentonite (&gt;90% montmorillonite). A series
            of static and dynamic experiments were conducted at two
            different temperatures (4 and 25 °C) to investigate the effect
            of temperature and agitation (dynamic experiments) on virus
            adsorption onto clays. Appropriate adsorption isotherms were
            determined. Electrokinetic features of bacteriophages and
            clays were quantified at different pH and ionic strength (IS).
            Moreover, interaction energies between viruses and clays were
            calculated for the experimental conditions (pH 7 and IS ) 2
            mM) by applying the DLVO theory. The experimental results
            shown that virus adsorption increases linearly with suspended
            virus concentration. The observed distribution coefficient (Kd)
            was higher for MS2 than ΦX174. The observed Kd values were
            higher for the dynamic than static experiments, and increased
            with temperature. The results of this study provided basic
            information for the effectiveness of clays to remove viruses by
            adsorption from dilute aqueous solutions. No previous study
            has explored the combined effect of temperature and agitation
            on virus adsorption onto clays.

          <dc:description xml:lang="en">Summarization: Chemical oxidation technologies are often employed for the
            treatment of complex industrial
            effluents that are not amenable to conventional biological methods. The role of chemical oxidation depends
            on the treatment objectives andmay vary from partial remediation to complete mineralization. In the case
            of partial treatment, chemical oxidation aims at the selective removal of the more bioresistant fractions
            and their conversion to readily biodegradable intermediates that can subsequently be treated biologically.
            Coupling chemical pre-oxidation with biological post-treatment is conceptually beneficial as it can lead
            to increased overall treatment efficiencies compared with the efficiency of each individual stage. This
            paper reviews recent developments and highlights some important aspects that need to be addressed when
            considering such integrated schemes.

          <dc:description xml:lang="en">Summarization: The electrochemical oxidation of olive oil mill wastewaters over
            a titanium–tantalum–platinum–iridium anode was
            investigated. Batch experiments were conducted in a flow-through electrolytic cell with internal recycle at
            voltage of 5, 7
            and 9V, NaCl concentrations of 1%, 2% and 4%, recirculation rates of 0.4 and 0.62 L/s and initial chemical
            oxygen
            demand (COD) concentrations of 1475, 3060, 5180 and 6545 mg/L. The conversion of total phenols and COD as
            well as
            the extent of decolorization generally increased with increasing voltage, salinity and recirculation rate
            and decreasing
            initial concentration. In most cases, nearly complete degradation of phenols and decolorization were
            achieved at short
            treatment times up to 60 min; this was accompanied by a relatively low COD removal that never exceeded 40%
            even
            after prolonged (up to 240 min) times. The consumption of energy per unit mass of COD removed after 120 min
            of
            treatment was found to be a strong function of the operating conditions and was generally low at high
            initial
            concentrations and/or reduced salinity. The acute toxicity to marine bacteria Vibrio fischeri decreased
            slightly during
            the early stages of the reaction and this was attributed to the removal of phenols. However, as the reaction
            proceeded
            toxicity increased due to the formation of organochlorinated by-products as confirmed by GC/MS analysis. The
            toxicity to Daphnia magna increased sharply at short treatment times and remained quite high even after
            prolonged
            oxidation.

          <dc:description xml:lang="en">Summarization: A new and fast equilibrium-based solvent microextraction
            technique termed vortex-assisted
            liquid–liquid microextraction (VALLME) has been developed and used for the trace analysis of octylphenol,
            nonylphenol and bisphenol-A in water and wastewater samples. According to VALLME, dispersion of
            microvolumes of a low density extractant organic solvent into the aqueous sample is achieved by using
            for the first time vortex mixing, a mild emulsification procedure. The fine droplets formed could extract
            target analytes towards equilibrium faster because of the shorter diffusion distance and larger specific
            surface area. Upon centrifugation the floating extractant acceptor phase restored its initial single
            microdrop
            shape and was used for high-performance liquid chromatographic analysis. Different experimental
            parameters were controlled and the optimum conditions found were: 50l of octanol as the extractant
            phase; 20 ml aqueous donor samples; a 2 min vortex extraction time with the vortex agitator set at a
            2500rpm rotational speed; centrifugation for 2 min at 3500 rpm; no ionic strength or pH adjustment.
            The calculated calibration curves gave high levels of linearity yielding correlation coefficients (r2)
            greater
            than 0.9935. The repeatability and reproducibility of the proposed method were found to be good and
            the limits of the detection were calculated in the low g l−1 level ranging between 0.01 and 0.07g l−1.
            Matrix effects were determined by applying the proposed method to spiked tap, river water and treated
            municipal wastewater samples.

            chromatography capable of quantifying trace amounts of chlorobenzenes in environmental water samples is
            proposed. A Plackett–Burman design
            for screening was carried out in order to determine the significant experimental conditions affecting the
            HS-SDME process (namely drop volume,
            aqueous sample volume, stirring speed, ionic strength, extraction time and temperature), and then a central
            composite design was used to optimize
            the significant conditions. The optimum experimental conditions found from this statistical evaluation were:
            a 5 L microdrop of 1-butyl-3-
            methylimidazolium hexafluorophosphate, exposed for 37 min to the headspace of a 10mL aqueous sample placed
            in a 15mL vial, stirred at
            1580 rpm at room temperature and containing 30% (w/v) NaCl. The calculated calibration curves gave a high
            level of linearity for all target
            analytes with correlation coefficients ranging between 0.9981 and 0.9997. The repeatability of the proposed
            method, expressed as relative standard
            deviation, varied between 1.6 and 5.1% (n = 5). The limits of detection ranged between 0.102 and 0.203 gL−1.
            Matrix effects upon extraction
            were evaluated by analysing spiked tap and river water as well as effluent water samples originating from a
            municipal wastewater treatment plant.

          <dc:description xml:lang="en">Summarization: An impressive abundance of high quality scientific content about
            Earth’s biodiversity and natural history available in Natural History Museums (NHMs) around Europe remains
            largely unexploited due to a number of barriers, such as: the lack of interconnection and interoperability
            between the management systems used by museums, the lack of centralized access through a European point of
            reference like Europeana, and the inadequacy of the current metadata and content organization. To cope with
            these problems, the Natural Europe project offers a coordinated solution at European level. Cultural
            heritage content is collected from six Natural History Museums around Europe into a federation of European
            Natural History Digital Libraries that is directly connected with Europeana.eu. This paper presents the
            Natural Europe Cultural Digital Libraries Federation infrastructure consisting of: (a) The Natural Europe
            Cultural Environment (NECE), i.e. the infrastructure and toolset deployed on each NHM allowing their
            curators to publish, semantically describe, manage and disseminate the Cultural Heritage Objects (CHOs) they
            contribute to the project, and (b) the Natural Europe Cultural Heritage Infrastructure (NECHI)
            interconnecting NHM digital libraries and further exposing their metadata records to Europeana.eu.

            appropriate tools and services that (a) allow the participating NHMs to uniformly describe and semantically
            annotate their content according to international standards and specifications, (b) interconnect their
            digital libraries, and (c) expose metadata records for Natural History cultural heritage objects to

          <dc:description xml:lang="en">Summarization: The MPEG-7 is the dominant standard for multimedia content
            description; thus, the audiovisual Digital Library contents should be described in terms of MPEG-7. Since
            there exists a huge amount of audiovisual content in the cultural heritage domain, it is expected that
            several cultural heritage objects, as well as entities related with them (i.e. people, places, events etc.),
            have been described using MPEG-7. On the other hand, the dominant standard in the cultural heritage domain
            is the CIDOC/CRM; consequently, the MPEG-7 descriptions cannot be directly integrated in the cultural
            heritage digital libraries.
            We present in this paper a mapping model and a system that allow the transformation of the MPEG-7
            descriptions to CIDOC/CRM descriptions, thus allowing the exploitation of multimedia content annotations in
            the cultural heritage digital libraries. In addition, the proposed mapping model allows linking MPEG-7
            descriptions to CIDOC/CRM descriptions in a Linked Data scenario.

          <dc:description xml:lang="en">Summarization: Capturing Multimedia Events such as natural disasters, accident
            reports, building damage reports, political events, etc., are expensive functionalities due to the number
            and training of the people required, as well as the time involved in the capturing and post-processing of
            multimedia. In addition, the captured multimedia content often fails to give the viewer a comprehensive
            understanding of the event captured in context. We present a model and a mobile system for multimedia event
            capturing by a one-man-crew. The system supports: (a) the real time capturing of complex multimedia events
            of different types, (b) the recording of the capturing process and the metadata associated with the events,
            (c) the visualization of the events and the capturing process, and (d) the learning and preparation of the
            one-man-crew that will do the multimedia event capturing.

          <dc:description xml:lang="en">Summarization: Within the context of a European project exploring the
            development of programming skills in secondary education by means of modern educational programming
            languages, this paper proposes certain pedagogical methods, approaches and frameworks for enhancing the
            development of programming skills, and thereby increasing the number of students studying computer science
            both at school and university level. In particular, the aim of this paper is to explore the issues
            surrounding curriculum design for computer courses with a special focus on programming. It has been argued
            that the utilisation of learning activities that demonstrate specific pedagogic approaches (inquiry-based
            learning, collaborative learning, cognitive constructivism or activity based) is limited suggesting that
            teachers are not fully aware of how to apply different pedagogical considerations to their actual practice.
            This is more apparent in programming courses because of the increased level of abstraction which may cause
            certain difficulties in teaching and learning. The creation of curricula based on pedagogically-rich
            teaching and learning activities, and the introduction of Educational Programming Languages (EPLs) designed
            for teachers to teach students how to develop computer programs, may generate powerful learning
            opportunities. The main purpose of this paper is to outline the theoretical underpinning of teaching and
            learning EPLs, and to argue that, to be comprehensive, curriculum design for programming courses must
            consider important perspectives, each of which leads to specific ways of teaching programming. The paper
            starts by surveying the current state of computer science curriculum in the participating countries in the
            context of curriculum design, before looking at learning theories and EPLs that may be used to support
            informed decisions for pedagogically-driven programming course design. Each decision requires different
            approaches to teaching programming which are necessary for aligning theory and practice within a viable
            educational model. The paper concludes by proposing that information and communication technology (ICT)
            tools may provide a framework to design and structure teaching and learning activities for programming
            courses.

          <dc:description xml:lang="en">Summarization: SPARQL is today the standard access language for Semantic Web
            data. In the recent years XML databases have also acquired industrial importance due to the widespread
            applicability of XML in the Web. In this paper we present a framework that bridges the heterogeneity gap and
            creates an interoperable environment where SPARQL queries are used to access XML databases. Our approach
            assumes that fairly generic mappings between ontology constructs and XML Schema constructs have been
            automatically derived or manually specified. The mappings are used to automatically translate SPARQL queries
            to semantically equivalent XQuery queries which are used to access the XML databases. We present the
            algorithms and the implementation of SPARQL2XQuery framework, which is used for answering SPARQL queries
            over XML databases.

          <dc:description xml:lang="en">Summarization: We propose a framework that supports a federated environment
            based on a Mediator Architecture in the Semantic Web. The Mediator supports mappings between the OWL
            Ontology of the Mediator and the other ontologies in the federated sites. SPARQL queries submitted to the
            Mediator are decomposed and reformulated to SPARQL queries to the federated sites. The evaluated results
            return to the Mediator. In this paper we describe the mappings definition and encoding. We also discuss
            briefly the reformulation approach that is used by the Mediator system that we are currently implementing.

          <dc:description xml:lang="en">Summarization: The need for semantic processing of information and services has
            lead to the introduction of tools for the description and management of knowledge within organizations, such
            as RDF, OWL, and SPARQL. However, semantic applications may have to access data from diverse sources across
            the network. Thus, SPARQL queries may have to be submitted and evaluated against existing XML or relational
            databases, and the results transferred back to be assembled for further processing. In this paper we
            describe the SPARQL2XQuery framework, which translates the SPARQL queries to semantically equivalent XQuery
            queries for accessing XML databases from the Semantic Web environment.

          <dc:description xml:lang="en">Summarization: It is now accepted that powerful retrieval of multimedia data can
            be achieved with the integration of semantic and contextual metadata that relate to multimedia objects. In
            the case of objects related to culture and history there is a wealth of related information stored in
            Digital Libraries. CIDOC/CRM is a new, rapidly adopted standard in the field of cultural heritage that
            provides a very powerful model for encoding cultural heritage knowledge. In this paper we propose that
            knowledge is extracted and encoded in MPEG-7 multimedia object descriptions in an automatic manner so that
            the multimedia objects are augmented with very rich metadata descriptions coming from Digital Libraries. We
            analyze the mapping problem between CIDOC/CRM and MPEG-7 and we present the algorithms and a software system
            that supports this mapping.

          <dc:description xml:lang="en">Summarization: Cameras provide integrated GPS technology which makes them a
            powerful sensor for geographical context related images. They allow wireless connection to computers and the
            images can be automatically transferred to a PC or can be integrated into a GIS system. In this paper we
            propose an approach for spatial information retrieval from images using the concept of ontologies and
            semantic maps. The term of ontology is used in our case to describe spatial domain knowledge to enhance the
            search capability and image annotation. The objects are represented by their location in semantic maps. We
            describe a developed prototype system with a database design for ontologies and semantic maps. We
            demonstrate the automatic image annotation and the visualization of the spatial queries. The system is
            oriented to the area of culture and tourism and provides a user friendly interface.

          <dc:description xml:lang="en">Summarization: We present in this paper a framework that provides support for
            interoperability between XML
            Schema based and OWL based applications. In particular, we describe how the information
            exchange between such applications is achieved, through the transformations of XML
            documents to OWL/RDF descriptions and of OWL/RDF descriptions to (parts of) valid XML
            documents. This functionality is built on top of OWL ontologies that fully capture the semantics
            of the XML Schemas. These ontologies are the outcome of the application of the XS2OWL
            mapping model that we have developed on an XML Schema. This way, the work reported here
            integrates and extends our previous work on the XS2OWL mapping model to take into account,
            in addition to the transformation of XML Schemas to OWL-DL ontologies, the transformation
            of XML documents to OWL/RDF descriptions and vice versa.

          <dc:description xml:lang="en">Summarization: Several standards are expressed using XML Schema syntax, since
            the XML is the default standard for data exchange in the Internet. However, several applications need
            semantic support offered by domain ontologies and semantic Web tools like logic-based reasoners. Thus, there
            is a strong need for interoperability between XML Schema and OWL. This can be achieved if the XML schema
            constructs are expressed in OWL, where the enrichment with OWL domain ontologies and further semantic
            processing are possible. After semantic processing, the derived OWL constructs should be converted back to
            instances of the original schema. We present in this paper XS2OWL, a model and a sys-tem that allow the
            transformation of XML Schemas to OWL-DL constructs. These constructs can be used to drive the automatic
            creation of OWL domain ontologies and individuals. The XS2OWL transformation model allows the cor-rect
            conversion of the derived knowledge from OWL-DL back to XML con-structs valid according to the original XML
            Schemas, in order to be used trans-parently by the applications that follow XML Schema syntax of the
            standards.

          <dc:description xml:lang="en">Summarization: The domination of XML in the Internet for data exchange has led
            to the development of standards with XML Schema syntax for several application domains. Advanced semantic
            support, provided by domain ontologies and se-mantic Web tools like logic-based reasoners, is still very
            useful for many appli-cations. In order to provide it, interoperability between XML Schema and OWL is
            necessary so that XML schemas can be converted to OWL. This way, the semantics of the standards can be
            enriched with domain knowledge encoded in OWL domain ontologies and further semantic processing may take
            place. In or-der to achieve interoperability between XML Schema and OWL, we have de-veloped XS2OWL, a model
            and a system that are presented in this paper and enable the automatic transformation of XML Schemas in
            OWL-DL. XS2OWL also enables the consistent transformation of the derived knowledge (individu-als) from
            OWL-DL to XML constructs that obey the original XML Schemas.

          <dc:description xml:lang="en">Summarization: In a Digital Business Ecosystem (DBE) information on the
            businesses and the services they provide may be described in terms of models and data which are used to
            semantically discover partners and services. The Object Management Group (OMG) defines a four layered
            modelling architecture, the Model Driven Architecture (MDA), which provides mechanisms for rapid development
            of modelling languages addressing domain problems using the Meta Object Facility (MOF). MOF incorporates
            object oriented concepts and is a subset of UML. Furthermore, as users typically don’t know how to make
            requests, the system has to be tolerant. The Query Metamodel Language (QML) is a language that ex-ploits the
            Object Constraint Language (OCL) (which is very closely associated with UML and therefore MOF) to provide
            powerful query support on model repositories. This paper presents the motivation for QML along with its
            abstract syn-tax. It also introduces the framework for QML processing that incorporates information
            retrieval functionality and is used to formulate fuzzy queries using the extended boolean model. It
            describes how QML is integrated in the MOF architecture and how semantic expansion of queries and evaluation
            can be done in an effective way.

          <dc:description xml:lang="en">Summarization: One of the most important applications of Digital Libraries (DL)
            is learning. However, DLs and their standards have been developed independently on eLearning applications
            and their standards, raising interoperability issues between digital libraries and eLearning applications.
            In order to enable the development of eLearning applications that easily exploit DL contents it is crucial
            to bridge the interoperability gap between digital libraries and eLearning applications. For this purpose, a
            generic interoperability framework has been developed that could also be applied to other types of
            applications which are built on top of digital libraries, although this paper focuses on the detailed
            requirements of the eLearning applications. In this context, a framework and an algorithm for supporting
            personalization in elearning applications has been developed that performs automatic, on-demand, creation of
            personalized learning experiences using reusable (audiovisual) learning objects, taking into account the
            learner profiles and a set of abstract training scenarios (pedagogical templates). From a technical point of
            view, all the framework components have been organized into a service-oriented Architecture that Supports
            Interoperability between Digital Libraries and ELearning Applications (ASIDE). A prototype of the ASIDE
            Framework has been implemented.

          <dc:description xml:lang="en">Summarization: The measurement of the semantic relatedness has many applications
            in natural language processing, and many different measures have been proposed. Most of these measures use
            WordNet as their central resource and not domain ontologies of a particular context. We propose and evaluate
            a semantic relatedness measure for OWL domain ontologies that concludes to the semantic ranking of
            ontological, grammatically-related structures. This procedure is used to disambiguate in a particular domain
            of context and represent in an ontology query language, natural language expressions. The ontology query
            language that we use is the SPARQL. The construction of the queries is automated and also dependent on the
            semantic relatedness measurement of ontology concepts. The methodology has been successfully integrated into
            the OntoNL Framework, a natural language interface generator for knowledge repositories. The
            experimentations show a good performance in a number of OWL ontologies.

            re-usable components for automating as much as possible
            the building of natural language interfaces to information

            OntoNL has semantic analysis components which exploit
            domain ontologies to provide better disambiguation of the
            user input. We present in this paper the algorithms used
            for semantic processing of the natural language queries, as
            well as an ontology-driven semantic relatedness measure
            developed for this purpose. We also present extensive evaluation
            results with different ontologies using human subjects.

          <dc:description xml:lang="en">Summarization: Semantic interoperability is usually provided in
            open environments through standards and domain ontologies.
            The dominant standards for multimedia content
            and service descriptions are MPEG-7 and MPEG-
            21. The MPEG-7 Semantic DS has powerful semantic
            description capabilities and supports using semantic
            entities specified in domain ontologies in multimedia
            content descriptions. However, the MPEG-7/21 Usage
            Environment allows neither the specification of semantic
            user preferences nor the exploitation of domain
            knowledge and MPEG-7 semantic metadata descriptions.
            In addition, the users cannot explicitly specify, in
            the hierarchical MPEG-7/21 filtering and search preferences,
            the boolean operators that should be used
            during content filtering to combine the hierarchy components.
            We think these as serious limitations and we
            propose a hierarchical semantic user preference model
            that allows for the explicit specification of boolean
            operators. Then, we present the application of the
            model in MPEG-7/21 and the model implementation
            within the DS-MIRF framework.

          <dc:description xml:lang="en">Summarization: eLearning applications are immensely more valuable when they can
            use the wealth of information that exists in multimedia digital libraries. However, digital libraries and
            their standards developed independently on eLearning applications and their standards. It is crucial to
            bridge the interoperability gap between digital libraries and eLearning applications in order to enable the
            construction of eLearning applications that easily exploit digital library contents. We present ASIDE, an
            integrated architecture that supports interoperability between digital libraries and eLearning applications.
            The architecture is service oriented and supports multiple contexts and views of the digital objects of a
            library. These views can be utilized by eLearning applications of the digital library for the automatic
            construction of personalized learning experiences selecting learning objects from the reusable objects of
            the digital library.

          <dc:description xml:lang="en">Summarization: A great challenge in information visualization today is to
            provide models and software that effectively integrate the graphics content of scenes with domain-specific
            knowledge so that the users can effectively query, interpret, personalize and manipulate the visualized
            information [1]. Moreover, it is important that the intelligent visualization applications are interoperable
            in the semantic web environment and thus, require that the models and software supporting them integrate
            state-of-the-art international standards for knowledge representation, graphics and multimedia. In this
            paper, we present a model, a methodology and a software framework for the semantic web (Intelligent 3D
            Visualization Platform - I3DVP) for the development of interoperable intelligent visualization applications
            that support the coupling of graphics and virtual reality scenes with domain knowledge of different domains.
            The graphics content and the semantics of the scenes are married into a consistent and cohesive ontological
            model while at the same time knowledge- based techniques for the querying, manipulation, and semantic
            personalization of the scenes are introduced. We also provide methods for knowledge driven information
            visualization and visualization- aided decision making based on inference by reasoning.

          <dc:description xml:lang="en">Summarization: The most important application of Digital Libraries (DL) is to
            support knowledge and learning purposes. However, DLs and their standards have been developed independently
            of eLearning applications and their standards. For that, interoperability issues between digital libraries
            and eLearning applications are risen (complex and multilevel problem). In order to enable the construction
            of eLearning applications that easily exploit DL contents it is crucial to bridge the interoperability gap
            between digital libraries and eLearning applications. Task 5.4 is exploring the interoperability of
            eLearning applications and Digital Libraries looking particularly at data models, standards and workflows.
            The aim is to study the major standards for digital libraries (e.g. METS), eLearning (e.g. SCORM) and
            audio-visual content description (e.g. MPEG-7), and to produce mappings among them. Based on this, the
            objective is to develop an integration framework and a service-oriented architecture which will be validated
            by a specific demonstrator.
