Given an index set X, a collection IB of subsets of X, and a collection (` x : x 2 X) of commuting linear maps on some linear space, the family of linear operators whose joint kernel K = K(IB) is sought consists of alì A := Q a2Aà with A any subset of X which intersects every B 2 IB. It is shown that certain conditions on IB and`, used in BRS] to obtain the inequality dim K(IB) X B2I B dim K(fB...
Les politiques d’infrastructures constituent un levier essentiel pour les efforts de réduction des émissions gaz à effet serre et d’adaptation territoires aux conséquences du réchauffement climatique. Dans la perspective transition environnementale en France, investissements significatifs devront être réalisés dans années venir transforme...
In this work, the optical properties dependence of Multi-Walled Carbon Nanotubes (MWNT) on concentration was discussed. MWNT samples were prepared in polypyrrole by an electrochemical polymerization of monomers, in the presence of different concentrations of MWNTs, using Sodium Dodecyl-Benzen-Sulfonate (SDBS) as surfactant at room temperature. The nonlinear refractive and nonlinear absorbtion i...
Face aux nombreux défis sociétaux à relever (environnement, sécurité alimentaire, santé), différentes formes d’agriculture sont envisagées. Agriculture biologique, agriculture de conservation des sols et maintenant régénératrice trois récits fondateurs se référant l’agroécologie. Toutefois, l’agriculture régénératrice, nouvelle arrivée en France, reste ambiguë. Nous proposons un cadre d’analyse...
