Download or read book Ionisation et dissociation par impact lectronique d ions mol culaires d int r t atmosph rique et thermonucl aire written by Julien Lecointre and published by Presses univ. de Louvain. This book was released on 2007 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dans les milieux ionisés existe un grand nombre d’espèces chimiques. Beaucoup sont en quantité minoritaire mais jouent pourtant, par leur grande réactivité, un rôle essentiel dans les processus de transformation chimique. Cette étude s’intéresse à la structure et à la dynamique des ions moléculaires, ainsi qu’aux collisions réactives pour des systèmes intervenant dans les atmosphères planétaires et dans le milieu interstellaire, comme les réactions mettant en jeu le monoxyde de carbone. Des modélisations numériques sont nécessaires à la préparation des expériences de fusion thermonucléaire. Enrichis par les résultats expérimentaux, concernant les ions d’hydrocarbures tels que le méthane, ils fournissent une aide pour l'interprétation des phénomènes observés dans les tokamaks. L’identification des réactions physiques à l’origine de la présence de particules dans le plasma est une étape importante afin de comprendre les environnements ionisés. Les systèmes examinés à Louvain-la-Neuve sont donc choisis pour leur intérêt immédiat en astrophysique ou en physique des plasmas. Alors que la connaissance des processus d'ionisation par impact d'électrons d’espèces atomiques ou ioniques simples est bien établie, ce n’est pas encore le cas lorsque la cible primaire est un ion moléculaire. L'existence d'au moins un degré de liberté supplémentaire rend possible la dissociation de l'ion moléculaire initial en plusieurs fragments, une partie de l’énergie potentielle est alors transférée sous forme d’énergie cinétique aux produits. En conséquence, ceux-ci sont généralement distribués dans de larges gammes angulaire et énergétique. L’analyse fine des distributions permet d’étudier les détails de la collision électronique. L’expérience a pour thématique majeure la mesure des sections efficaces absolues en fonction de l’énergie des électrons projectiles incidents, pour des réactions impliquant des espèces ioniques polyatomiques. L’observation des seuils de réaction et de l’énergie cinétique des fragments permet de déterminer la zone de Franck-Condon accessible et les états moléculaires impliqués dans les processus considérés. Les travaux réalisés au laboratoire ont démontré que l'appareillage existant est bien approprié à ce type d’étude. A un niveau plus fondamental, l’examen comparatif minutieux des présentes mesures, des résultats issus d’autres expériences et des prédictions des formalismes semi-empiriques, permet d’améliorer la connaissance des phénomènes collisionnels.

Download or read book An Introduction to Differential Manifolds written by Jacques Lafontaine and published by Springer. This book was released on 2015-07-29 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an introduction to differential manifolds. It gives solid preliminaries for more advanced topics: Riemannian manifolds, differential topology, Lie theory. It presupposes little background: the reader is only expected to master basic differential calculus, and a little point-set topology. The book covers the main topics of differential geometry: manifolds, tangent space, vector fields, differential forms, Lie groups, and a few more sophisticated topics such as de Rham cohomology, degree theory and the Gauss-Bonnet theorem for surfaces. Its ambition is to give solid foundations. In particular, the introduction of “abstract” notions such as manifolds or differential forms is motivated via questions and examples from mathematics or theoretical physics. More than 150 exercises, some of them easy and classical, some others more sophisticated, will help the beginner as well as the more expert reader. Solutions are provided for most of them. The book should be of interest to various readers: undergraduate and graduate students for a first contact to differential manifolds, mathematicians from other fields and physicists who wish to acquire some feeling about this beautiful theory. The original French text Introduction aux variétés différentielles has been a best-seller in its category in France for many years. Jacques Lafontaine was successively assistant Professor at Paris Diderot University and Professor at the University of Montpellier, where he is presently emeritus. His main research interests are Riemannian and pseudo-Riemannian geometry, including some aspects of mathematical relativity. Besides his personal research articles, he was involved in several textbooks and research monographs.

Available in PDF, EPUB and Kindle. Book excerpt: Cet ouvrage, devenu célèbre sous son sigle MCSE, a déjà été utilisé par plus de 50 000 étudiants, chercheurs, professionnels. L'objectif est de lire et écrire des textes en anglais scientifique avec facilité et pertinence. L'ouvrage est conçu pour que l'apprenant devienne un véritable utilisateur de l'anglais. La méthode originale repose sur l'analyse des fonctions et structures nécessaires : measurement, frequency, comparison, modification, link words, time, cause and consequence, hypothesis, modality, purpose and process, impersonal forms, compound nouns and adjectives. Dans chaque unit, des tests d'auto-évaluation permettent de se situer et de construire son parcours de formation, d'abord en définissant ses objectifs à l'aide des key points et du lexis, puis, de façon plus personnalisée, en puisant dans les examples in context, checkpoints (back to basics, word web), web search, FAQs... MCSE est l'outil de base d'une méthode qui comprend aussi d'autres outils dans la même collection (Listening Comprehension for Scientiflc English et Speaking Skills in Scientitic English). L'ouvrage est destiné à tout apprenant de niveau baccalauréat qui désire acquérir une réelle compétence dans l'écriture et la lecture de textes en anglais scientifique.
