The demonstration of an electrically pumped organic laser remains a major issue of organic optoelectronics for several decades. This goal requires an improved device configuration so as to reduce losses which are intrinsically higher under electrical excitation compared to optical pumping. Moreover a systematic investigation of the material properties is still missing and should lead to a relia...
متن کاملL'analyse Statistique Implicative: Une Des Méthodes D'analyse Des Données En Didactique
Through the analysis of research experiences in Didactics of Mathematics data have been compared both with the implicative analysis of Gras and with the factorial analysis of correspondences. The results of this comparison highlighted that implicative analysis, when supplementary variables are introduced, proves to be more incisive in the reading of the contingency. Factorial analysis, instead,...
متن کاملDépistage des maladies cardiovasculaires chez des étudiants de l'Université de Douala et influence des activités physiques et sportives
Introduction: Les maladies cardiovasculaires (MCV) constituent l’une des principales causes de mortalité dans les pays en développement. Le dépistage de ces dernières chez des jeunes est un défi dans la lutte contre leur expansion. Le but de cette étude était de dépister ces maladies au sein d’une population jeunes d’étudiants camerounais. Methodes: Deux mille six cent cinquante-huit étudiants ...

Sexual parasites are intracellular symbionts capable of manipulating the reproduction of their hosts. They are widespread in Arthropods where they display a wide range of reproductive manipulations; these can be potentially involved in the evolution of mating systems, speciation, gene acquisition and sex determination. In particular, Wolbachia is thought to infect more than 66% of insect specie...

Mots-clés: adsorption de CO2, thermographie IR, spectroscopie DRIFT, méthodologie haut-débit, modélisation thermique, chaleur d'adsorption, technique inverse. Abstract: CO2 capture via adsorption process on porous materials (adsorbents) is a promising alternative due to its high selectivity and low energy penalties. We have investigated in-situ CO2 adsorption on solid adsorbents by combining Di...
