Le concept de système en thermodynamique
Autor: Maxime Nagels, Abdelkader Anakkar, Abdelhalim Guelzim
Publikováno v: J3eA. 21:2045
Une réflexion a semblé nécessaire sur les différentes définitions proposées dans la littérature pour la no-tion de système thermodynamique. A partir d’une analyse détaillée de 45 ouvrages du supérieur, nous avons parcouru la diversité d

Approches thermodynamiques globale et locale appliquées à un cycle reversible triangulaire à transformation « infinitherme »
Autor: Maxime Nagels, Abdelkader Anakkar, Abdelhalim Guelzim
Publikováno v: J3eA. 21:2046
L’enseignement de la thermodynamique peut se faire selon deux approches. L’approche globale reposant sur une variation finie des fonctions d’état et l’approche locale utilisant l’écriture différentielle. Lors de la réforme des programme

Preparative HPLC separation of methoxytetralins, ligands for melatonin receptors, containing two chiral centers with polysaccharide chiral stationary phases. Determination of enantiomeric purity
Autor: Jean-Paul Bonte, Abdelhalim Guelzim, Emmanuelle Lipka, Saïd Yous, Claude Vaccher
Publikováno v: Journal of Biochemical and Biophysical Methods. 64:46-58
Preparative chromatography was used to obtain approximately 200 mg of each of the four individual isomers of the three methoxytetrahydronaphthalenic derivatives, new agonist and antagonist ligands for melatonin receptors to be tested for binding. The
