Contamination of NH4+, as main inorganic contaminant, resulted from disposal of ammoniacal liquor at a former coal carbonisation plant at Mansfield, UK. Previous research for evaluating natural attenuation (Davison, 1998; Davison and Lerner, 2000; Jones, 2001; Jones et al., 1998; Jones and Lerner, 2001) revealed strong retardation of NH4+ in the aquifer due to cation exchange with existing cations on the sediment. After disposal of ammoniacal liquor, NH4+ entered the aquifer and equilibrium took place between NH4+, the existing cations and the available exchange sites. An existing hydraulic gradient keeps flushing the contaminated aquifer with pristine background water. NH4+ desorbs progressively due to new cation exchange equilibrium when the input of NH4+ decreases or eventually stops. In order to be able to model the reactive transport of NH4+, a reaction module is set up for future 2D/3D reactive transport modelling of NH4+ using PHT3D. In a first approach a conceptual 1D-model example is considered and two multicomponent reactive transport models, PHT3D (Prommer and Barry, 2001; Prommer et al., 1999) and PHREEQC (Parkhurst and Appelo, 1999), are compared. In the 1D-model example, the flushing of ammonium contaminated groundwater by pristine background water is simulated. The included processes are advection, dispersion and cation exchange between NH4+, Ca2+, Mg2+, K+, Na+ and the sediment. As both models are using the same geochemical module, the comparison focuses on the coupling approach between the transport and geochemical modules. Results show that large numbers of pore volumes (i.e., a nondimensional time parameter where elapsed time is divided by the hydrodynamic residence time (Brusseau, 1994)) are needed to flush the NH4+ off the aquifer sediment. From the comparison of simulation results compiled with the two codes it is clear that an appropriate choice of the reaction step size for the sequential coupling between the transport and geochemistry modules, is a major point for accuracy of the model predictions.

Using a plane-wave pseudopotential approach to density functional theory, we investigate the degree of electron localization in lithium niobate. We pay a particular attention to its variation during the phase transition and to the relationship with the electronic structure and the Born effective charges in this material. A band-by-band decomposition allows us to focus on the different bands composing the energy spectrum of this compound. At variance with previous calculations based on finite differences, the localization tensor has been obtained using linear-response techniques. [less ▲]

Doping at the Mn-site in CMR manganate-based perovskites has been shown to affect strongly the physical properties of those compounds. We study here the effect of copper substitution in the low doping range on the electrical transport properties of La0.7Ca0.3MnO3. It turns out that the transition temperature decrease observed in doped samples can be drastically reduced by addition of silicon dioxide SiO2. It is shown that copper is trapped in a secondary phase composed of La,Ca,Si,Cu and O. The resultant Mn-site vacancies appear to be less detrimental to the electronic conduction than the likely antiferromagnetic clusters induced by the copper ions in the Mn-O network. [less ▲]

For the k-ary numeration system, we characterize the sets of integers such that the corresponding representations make up a star-free regular language. This result can be transposed to some linear numeration systems built upon a Pisot number like the Fibonacci system and also to k-adic numeration systems. Moreover we study the problem of the base dependence of this property and obtain results which are related to Cobham's Theorem. [less ▲]

The design of composite structures is considered here. The approximation concepts approach is used to solve the optimization problem. The convex approximations of the MMA family are briefly described. Several modifications of these approximations are presented. They are now based on gradient information at two successive iterations, avoiding the use of the expensive second-order derivatives. A two-point fitting scheme is also described, where the function value at the preceding design point is used to improve the approximation. Numerical examples compare these new purely non-monotonous schemes to the existing ones for the selection of optimal fibers orientations in laminates. It is shown how these two-point based approximations are well adapted to the problem and can improve the optimization task, leading to reasonable computational efforts. A procedure is also derived for considering simultaneously monotonous and non-monotonous structural behaviors. The resulting generalized approximation scheme is well suited for the optimization of composite structures when both plies thickness and fibers orientations are considered as design variables. It is concluded that the newly developed approximation schemes of the MMA family are reliable for composite structures optimization. All the studied approximations are convex and separable: the optimization problem can then be solved using a dual approach. (C) 2002 Civil-Comp Ltd and Elsevier Science Ltd. All rights reserved.

Whether recognition memory can be preserved relative to recall in global amnesia is a matter of debate. Some studies suggest that amnesic patients with selective lesion to the hippocampal circuit show a relatively normal recognition memory in the presence of impaired recall. However, other findings did not support this assumption. We investigated the recognition memory performance of a patient (ER) who became amnesic following a carbon monoxide poisoning. The MR scan revealed bilateral lesions to the pallidum. Based on the aetiology, a hippocampal lesion is suspected, but needs to be confirmed by a volumetric analysis. The recall and recognition performance of the patient was tested by means of the nonverbal subtests of the Doors and People Test Battery, which were matched on difficulty. On these subtests, ER’s recall performance was much more impaired than his recognition memory. ER’s recognition memory performance was further examined on a yes-no and a forced-choice recognition memory task, using faces as material. On the yes-no task, ER’s hit rate was normal, but he made a lot of false alarms compared to control subjects. By contrast, his forced-choice recognition memory was completely normal. This suggests that ER is able to use the familiarity process to make recognition decisions. Familiarity and recollection were finally investigated with a recognition task using the Process Dissociation Procedure (Jacoby, 1991). On this task, ER’s familiarity score was normal, whereas his recollection score was lower. These results support the assumption that familiarity-based recognition memory can be preserved in amnesia.

Cyproterone acetate (CPA) is a steroidal antiandrogen with a progestogenic activity. Given that this molecule has a very poor water solubility (2.1 μg/mL), different cyclodextrins (CDs) were tested to form inclusion complexes and to increase solubility. Two different techniques were compared to study the affinity between CPA and CDs: phase-solubility studies and NMR spectroscopy. The stoichiometry and the stability constant could be determined for most complexes with the aid of phase-solubility studies. The greatest increase in solubility was achieved with the methylated β-CDs, but hydroxypropylated β- and γ -CDs also gave enhanced solubilities. 1H-NMR studies showed a solubility increase similar to that found with phase-solubility studies. The proof of inclusion in the 2,6-dimethyl-β-CD (DIMEB) was shown by 1H-NMR and t-ROESY spectra. [less ▲]

Highly ordered hexagonal mesostructures (CMI-1 compounds) can be obtained under mild acidic conditions by working at low concentrations of non-ionic decaoxyethylene cetyl ether [C16(EO)10]. The present work shows that it is possible to gain control at the nanometer scale over the packing symmetry of the channels, as well as at the micrometer level over the morphology of the particles by varying the surfactant / silica molar ratio and the hydrothermal treatment conditions. Very high loadings of silica precursors typically afford highly ordered hexagonal CMI-1 compounds whereas an increase of the surfactant / silica molar ratio results in materials with a more disordered channel array. In a parallel way, very low molar ratios of surfactant / silica lead to ropes, gyroids and toroids whereas spheres are the most stable shape with the lower quantities of silica. From this point, it appears thus that not only the structure but also the morphologies encountered for MCM-41 type mesoporous silica can be reproduced with a non-ionic templating agent. [less ▲]

The present work deals with a systematic study of mesoporous materials synthesis. A series of polyoxyethylene alkyl ether surfactants such as C 13(EO) n (n = 6, 12, 18), C 16(EO) 10, C 18(EO) 10 have been used. It is revealed that the surfactant conformation changed with the heating temperature. Indeed, at higher temperatures, a more extended molecular conformation can be obtained, which leads to materials with larger pore sizes. We have also shown that the interaction between template and silica disturbs the hexagonal array of micelles in solution leading to the formation of DWM-1 or DWM-2 compounds for concentrated micellar solution. We have also correlated the structural characteristics of the recovered mesoporous molecular sieves with the V H/V L ratio of the template. [less ▲]

Interestingly, the most recent study reported the fewest species (11), the most previous contained 12 and the second one showed 17 species, This confused situation and the paucity of data initiated the authors to identify the green lacewing collection of the Gembloux University of Agricultural Sciences, where lacewings from different parts of Belgium were preserved, and also to collect chrysopids regularly, Summarising the species reported in the literature and caught during sampling, 18 green lacewing species have been verified in Belgium: Nothochrysa fulviceps, Nothochrysa capitata, Hypochrysa elegans, Nineta flava, Nineta vittata, Nineta pallida, Chrysotropia ciliata, Chrysopa perla, Chrysopa dorsalis, Chrysopa abbreviata, Chrysopa formosa, Chrysopa phlyllochroma, Chrysopa pallens, Dichochrysa flavifrons, Dichochrysa prasina, Dichochrysa ventralis, Chrysoperla carnea, Cunctochrysa albolineata. Considering the known references, one species, Nineta pallida proved to be new for the Belgian fauna. [less ▲]

Concentrations of polyoxyethylene alkyl ether surfactants located in the hexagonal H1 micellar domain typically afford disordered mesoporous structures of wormhole-like channels after polymerization of the inorganic precursor in solution. The effect of hydrothermal treatment duration and temperature on the characteristics of the obtained disordered DWM (Disordered Wormhole-like Mesostructure) compounds has been investigated. Thermal stability of these samples has also been studied and appears to be superior to that of MCM-41 type materials. If the weight percentage of surfactant in solution is however decreased, well-ordered hexagonal CMI-1 can be directly obtained. In this case, a co-operative mechanism leading to spherical particles of organized channel structures has been proposed. Influence of the surfactant concentration on the arrangement has been discussed in detail. [less ▲]

L’article identifie en profondeur les facteurs déterminants, et l’ampleur de leur influence, relatifs à une utilisation plus intensive du mode de transport fluvial et au concept de développement durable. Il est donc important de comprendre quelles sont les barrières qui empêchent le glissement de marchandises de la route vers la voie d’eau sur le réseau belge où des conditions spécifiques économiques, administratives, organisationnelles, politiques et d’infrastructure existent. Il est aussi fondamental d’être attentif aux facteurs relatifs à la capacité du mode fluvial à s’intégrer dans des chaînes de transport intermodales. L’article se subdivise en trois parties, à savoir : - possibilités de glissement de marchandises sur les corridors fluviaux belges. - obstacles au glissement. - conditions préalables au glissement; exigences nécessaires pour une pleine intégration de la navigation intérieure dans les chaînes intermodales de transport; proposition de mesures concrètes.

UV images of Jupiter's aurora obtained with the HST STIS instrument reveal much detail in the distribution of emissions from Io's magnetic footprint on Jupiter, including extended trails of emission in the downstream direction. Emissions are also seen from the magnetic footprints of Ganymede and Europa, relatively much fainter and point-like in spatial extent. Knowledge of the statistical properties of these emissions, in terms of their locations and brightnesses, was greatly advanced in a comprehensive series of images obtained during the Millennium campaign in Dec. 2000 - Jan. 2001. These images provide sufficient spatial coverage to give a good indication of the auroral oval locations mapping to Io and Ganymede, and a few points mapping to Europa. The observed variations in footprint properties provide indications of the nature of the electrodynamic interactions of the satellites with Jupiter's magnetic field. These and other indicators also show the direction that magnetic field models should take to better describe Jupiter's internal magnetic field. Contributing evidence comes from the locus of footprint latitudes, and their deviations from the VIP4 model. The latitudinal distance between the Io and Ganymede footprint loci indicates variations in the local field strength, with larger separations corresponding to a weaker field. These separations, and the distance from and distortion of the main oval, indicate an anomalously weak field region in the north near 90[SUP]o[/SUP] longitude. This work has been supported by NASA in STScI grants GO-08171-97A and GO-08657-01A to the University of Michigan. [less ▲]

Jovian auroral spectra have been observed with the Space Telescope Imaging Spectrometer (STIS) in both hemispheres since 1997, including during the recent Cassini Jupiter millenium campaign. The time-tagged G140L STIS spectra used for this study cover the 1100-1700 Ì· range which includes the Lyman (B-X) bands and continuum and the Werner (C-X) bands. Time-dependent spectroscopy with spatial resolution along the 25 arcsec slit makes it possible to follow spectral and temporal variations in different regions of the aurora. FUV images observed on the same HST orbit were obtained to put the spectral data into the global morphology context. Synchronous observations of spectral domains absorbed or not by CH4 and other hydrocarbons are used to determine the FUV color ratio and the depth of the auroral emission relative to the methane homopause. Large variations of the color ratio across the auroral oval are observed. The time evolution of the mean electron energy and its possible correlation with the precipitated energy flux are investigated. It is found that the mean electron energy generally positively correlates with the auroral brightness. In contrast, flares occasionally observed in the polar cap can correspond to a softening or a hardening of the precipitation. The mean electron energy associated with the Io trail is approximately constant and shows less hydrocarbon absorption than the higher latitude aurora. [less ▲]

We propose an improvement of our RLS (Receiver-driven Layered multicast with Synchronization points) protocol, called CIFL for “Coding-Independent Fair Layered mulaticast”, along two axes. In CIFL, each receiver of a layered multicast transmission will try and find the adequate number of layers to subscribe to, so that the associated throughput is fair towards TCP and stable in steady-state. The first improvement is that CIFL is not specific to any coding scheme. It can work as well with an exponentially distributed set of layers (where the throughput of each layer i equals the sum of the throughputs of all layers below i), or with layers of equal throughputs, or any other scheme. The second improvement is the excellent stability of the protocol which avoids useless join attempts by learning from its unsuccessful previous attempts in the same (or better) network conditions. Moreover, the protocol tries and reaches its ideal TCP-friendly as soon as possible by computing its target throughput in a clever way when an incipient congestion is confirmed. [less ▲]
