La variété β-NaMoO2(AsO4)

The title compound, sodium dioxidomolybdenum(VI) arsenate(V), β-NaMoO(2)AsO(4), was prepared by solid-state reaction at 953 K. In the crystal structure, the AsO(4) tetra-hedra and MoO(6) octa-hedra (both with m symmetry) share corner atoms to form a three-dimensional framework that delimits cavities parallel to [010] where disordered six-coordinated sodium cations (half-occupation) are located....

A Center Manifold Result for Delayed Neural Fields Equations

We develop a framework for the study of delayed neural fields equations and prove a center manifold theorem for these equations. Specific properties of delayed neural fields equations make it impossible to apply existing methods from the literature concerning center manifold results for functional differential equations. Our approach for the proof of the center manifold theorem uses the origina...

Modélisation par la méthode des équations intégrales de frontière de phénomènes de conduction surfacique sur les isolateurs pollués

The dielectric withstand capabilities of insulating materials is related to their surface electric field and potential distributions. These distributions, in the presence of polluting layers, are quite different from these encountered in classical electrostatics. This work is concerned with the application of boundary integral equations method to the calculation of electric fields and potential...
