Language profile of fragile-X syndrome people looks like the one of Down syndrome people, except for phonological and pragmatic abilities. It's this last aspect that we want to study and describe. If the pragmatic aspect of language is relatively preserve (excepting referential communication) in Down syndrome, it is one of the most impaired language component in fragile-X syndrome. Discourse of fragile-X persons generally contains a lot of repetitions, perseverations and stereotypy. Echolalia is also very frequent. These behaviors are well documented in the literature but, we do not know, for now, the reasons of these repetitions and perseverations. Are they the consequence of a real pragmatic disorder or the consequence of motor difficulties ? Another aspect of the pragmatic component of language remains almost unexplored in this pathology : the common ground management and the organisation of the old and the new information in conversation. It's this last point that we want to explore. Studying this topic in fragile-X syndrome allow is the continuity of our previous work on referential communication abilities in Down syndrome. Having data on both pathologies will lead to interesting theorical, practical and clinical comparisons. We decided to work with 6 to 12 years-old fragile-X boys. Groups of two boys will work together on referential communication tasks. We will propose traditional experimental situations (speaker and receptor with another child or with an adult) and more original situations in which we allow or not visual contact between the participants during the experimentation. By this, we want to see if, as certain researches claim it, visual contact will modify the nature, the quantity and the quality of verbal output in fragile-X syndrome children. [less ▲]

We report first-principles calculations on the structural properties of SrRuO 3/BaTiO3 (metal/ferroelectric) and BaO/BaTiO3 (insulator/ferroelectric) heterostructures, both of them paradigmatic systems for experimental measurements. Using a density-functional pseudopotential plane-wave method, as implemented in the ABINIT package, we have studied the changes in the interlayer spacing and the atomic rumpling. The substrates are explicitly considered in our simulations, so the lateral stress on the BaTiO3 thin films and mechanical boundary conditions are automatically taken into account. For the SrRuO3/BaTiO3 interface short-circuit boundary conditions are imposed. Results on free-standing BaTiO3 surfaces are also reported, showing good agreement with previous works. The ground state for all the structures studied here is paraelectric. [less ▲]

Simulation models of spray pattern are required for the dynamic behaviour assessment of sprayer booms. The reasons are their ease of use and their independence regarding variable operating conditions such as liquid properties and nozzle state, which interfere with the discrimination between various dynamic behaviours properties. Although such models have been developed for many decades, no international consensus has been reached on their use in a standardised test procedure. A consensual model is tested in the scope of standardisation specific needs. It uses ISO-5682/1 spray table measurements of the static distributions to compute three 2-D distribution at three heights using a filtered back-projection algorithm. These distributions are interpolated to generate a 3-D matrix of repartition at various heights. This 3-D matrix is used as nozzle distribution description in a dynamic distribution model where the dynamic distribution is computed as a summation of the static distribution at successive positions. The model kernel was found suitable to predict the repartition under a moving boom. [less ▲]

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 ▲]

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.

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 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.

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.

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 ▲]

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.

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 ▲]

The formation of nanostructured porous zirconia catalyst supports using non-ionic surfactants as templating agents has been studied in order to optimize the synthesis conditions without addition of structure stabilizing agents such as sulfate or phosphate anions. The effect of the quantity of added zirconium source with respect to the surfactant concentration in solution has been studied. We also examined the role played by the surfactant during the synthesis. Further investigations have shown that the pore diameters could be increased towards the mesoporous domain if heating time and temperature are raised. The present work reveals that the control of the balance between the precipitation rate of zirconia and the interaction of zirconium source will be fatal in the formation of nanostructured porous zirconia.

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 ▲]

The key physical phenomena associated with long-wavelength infrared emission and laser action in quantum cascade lasers based on InP/GaInAs/AlInAs and GaAs/AlGaAs heterostructures are reviewed. The effect of different tunnel injection schemes on the hot-electron energy distributions is compared. High-power superlattice lasers with improved high-energy injection schemes are described. The local temperature distribution, the thermal resistance and the hot-phonon effects are monitored in operating devices by micro-probe Raman and luminescence measurements. [less ▲]

A systematic kinetic study of mesoporous zirconia formation has been performed in order to optimize the synthesis conditions without addition of structure stabilizing agents such as sulfate or phosphate anions. We have investigated in particular the effect of synthesis time and temperature. On the basis of TEM, SEM XRD and N 2 adsorption-desorption results, a synthesis mechanism has been proposed. Low temperature or short duration afford supermicroporous materials and continuation of hydrothermal treatment makes the walls separating adjacent pores break down allowing the transformation to mesopores. The obtained materials have a uniform pore size and their surface can reach 400m 2/g. However, if hydrothermal treatment is performed at too high temperatures or for too long durations, mesoporous compounds are no longer obtained, but thermodynamically more stable crystalline zirconium oxides with very low specific surface area, namely the tetragonal and monoclinic forms, are the final phases that are more likely to appear.

This study consists in verifying the coherence of a few commonly used analysis methods of nitrogen adsorption-desorption isotherms. These methods were tested on model samples obtained by mechanically mixing two micro- and mesoporous solids respectively with known, mass proportions. Although the individual analysis methods may lead to discrepancies in the interpretation of the isotherms, their systematic comparison allows drawing a coherent picture of the porous texture.
