Cyclic Voltammetry and Impedance Spectroscopy Behavior Studies of Polyterthiophene Modified Electrode

We present in this work a study of the electrochemical behaviour of terthiophene and its corresponding polymer, which is obtained electrochemically as a film by cyclic voltammetry (CV) on platinum electrode. The analysis focuses essentially on the effect of two solvents acetonitrile and dichloromethane on the electrochemical behaviour of the obtained polymer. The electrochemical behavior of this material was investigated by cyclic voltammetry and electrochemical impedance spectroscopy (EIS). The voltammograms show that the film of polyterthiophene can oxide and reduce in two solutions; in acetonitrile, the oxidation current intensity is more important than in dichloromethane. The impedance plots show the semicircle which is characteristic of charge-transfer resistance at the electrode/polymer interface at high frequency and the diffusion process at low frequency

Les accidents de la route dans les médias de masse en Algérie

This research brief presents a content analysis of a sample of Algerian mass media’s coverage of road accidents in 2008. The written press’s coverage is judged as barely adequate while radio all but ignores the subject. Only television pays any attention and allots the necessary resources. These failings are due to the absence of a national policy and strategy for the prevention of road accidents

Enseigner l’égalité filles-garçons

International audienceL'Ecole compte parmi ses missions fondamentales celle de garantir l'égalité des chances entre les filles et des garçons. Les Ecoles supérieures du professorat et de l'éducation (ESPE) intègrent dans les enseignements du tronc commun la mobilisation contre les stéréotypes, notamment sexistes, et les discriminations ainsi que la promotion de l'égalité entre les filles et les garçons, les femmes et les hommes.Lutter contre les discriminations sexistes ? Gérer sa classe ? La prise de parole ? L'espace réservé aux élèves ? Réagir aux stéréotype sexiste et homophobes ? Eduquer à la sexualité ? Questioner la représentation des professions pour mieux orienter les élèves ? Enseigner l'EPS, l'histoire-géo, l'EMC, la grammaire, les langues, les sciences économiques ou les SVT au regard de la question de l'égalité fille-garçon ? Une quarantaine d'outils indispensables pour exercer le métier de professeur, de la maternelle au lycée répondront à toutes ces questions.- Chaque outil est traité de façon synthétique et imagée sur 2 ou 4 pages. - Chaque outil renvoie à des mises en oeuvre concrètes qui s'appuient sur une expérience de terrain des auteurs. - Des conseils méthodologiques, des remarques sur les contextes d'utilisation de ces outils, ainsi qu'un approfondissement des connaissances viennent compléter ces présentations

Impact of traditional and modern building materials on the thermal behavior and energy consumption of a courtyard house in the hot and dry climate

In this work, we studied the thermal behavior of mono or multilayer walls of various compositions consisting of traditional and modern building materials, in order to identify those that provide good comfort and better energy conservation in conditioning case in the context of a hot and dry climate for a courtyard house. The study is conducted with the TRNSYS-COMIS software. The thermo physical properties of modern building materials are those adopted by the Algerian regulations and those of adobe were determined in the laboratory LASIE at the University of La Rochelle. The results of this study show the impact of inertia on winter consumption, as well as the effectiveness of roof insulation in reducing cooling requirements. The adobe has good properties to improve comfort and energy savings but its stabilization with cement, to improve its mechanical properties decreases its thermal qualities
