Book excerpt: LA MAGNETOSPHERE TERRESTRE RESULTE DE L'INTERACTION DU CHAMP MAGNETIQUE INTERPLANETAIRE PORTE PAR LE VENT SOLAIRE AVEC LE CHAMP MAGNETIQUE D'ORIGINE PLANETAIRE. LA CAVITE MAGNETOSPHERIQUE AINSI CONSTITUEE N'EST PAS FERMEE ET IL EST ADMIS QU'IL EXISTE DES TRANSFERTS DE MASSE ET D'ENERGIE ENTRE LE VENT SOLAIRE ET LA MAGNETOSPHERE INTERNE. CES TRANSFERTS S'EFFECTUENT AU NIVEAU DES REGIONS DE RECONNEXION MAGNETIQUE, LA OU LA PRESSION MAGNETIQUE EST LOCALEMENT TRES FAIBLE. LES RAYONS DE GIRATIONS DES PARTICULES SONT ALORS TRES GRANDS ET PEUVENT ETRE DE L'ORDRE DE, OU SUPERIEUR AU RAYON DE COURBURE DES LIGNES DE CHAMP MAGNETIQUE. LE TRANSPORT DU PLASMA DEVIENT ALORS NON-ADIABATIQUE (RUPTURE DES INVARIANTS DU MOUVEMENT DEFINI DANS LE CADRE DE LA MECANIQUE HAMILTONIENNE) ET IL EN RESULTE UNE DEFORMATION DES FONCTIONS DE DISTRIBUTION. NOUS LES AVONS ETUDIEES DANS LES REGIONS DE RECONNEXION POUVANT EXISTER DANS LA QUEUE LOINTAINE DE LA MAGNETOSPHERE, AU VOISINAGE D'UN PLASMOIDE, DANS LA QUEUE PROCHE LORS DE SOUS-ORAGES MAGNETOSPHERIQUES, ET SUR LES FLANCS DE LA MAGNETOPAUSE (PAR INSTABILITE KELVIN-HELMHOLTZ). NOUS AVONS A L'AIDE DE SIMULATIONS NUMERIQUES PARTICULAIRES PREDIT DES SIGNATURES DANS LES FONCTIONS DE DISTRIBUTIONS QUE L'ON RETROUVE DANS CERTAIN CAS DANS LES OBSERVATIONS SATELLITES (GEOTAIL ET INTERBALL). PLUSIEURS MODELES ANALYTIQUES ONT ETE DEVELOPPES AFIN DE DETERMINER LA LOCALISATION ET LA TOPOLOGIE DES SITES DE RECONNEXION.

Available in PDF, EPUB and Kindle. Book excerpt: This is the first book to provide a comprehensive and state-of-the-art introduction to the novel and fast-evolving topic of in-situ produced cosmogenic nuclides. It presents an accessible introduction to the theoretical foundations, with explanations of relevant concepts starting at a basic level and building in sophistication. It incorporates, and draws on, methodological discussions and advances achieved within the international CRONUS (Cosmic-Ray Produced Nuclide Systematics) networks. Practical aspects such as sampling, analytical methods and data-interpretation are discussed in detail and an essential sampling checklist is provided. The full range of cosmogenic isotopes is covered and a wide spectrum of in-situ applications are described and illustrated with specific and generic examples of exposure dating, burial dating, erosion and uplift rates, and process model verification. Graduate students and experienced practitioners will find this book a vital source of information on the background concepts and practical applications in geomorphology, geography, soil-science, and geology.

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.

Book excerpt: Aeronomy, Part A is an attempt to make a comprehensive exposition of the processes in aeronomy, the study of composition, movement, and thermal balance of the upper regions of the planetary atmosphere. The text covers topics such as atmospheric regions and atmospheric density, the temperature and molecular mass of the atmosphere; the permanent constituents and the molecular and isotonic composition of the homosphere; and the transition from the homosphere to the heterosphere. Also covered are topics such as the temperature gradient and energies in the thermosphere, conditions at 200km and above 250km, solar radiation and ionization, and aeronomic reactions. The book is recommended for scientists, especially natural physicists, who would like to know more about the field of aeronomy and its advances.

Available in PDF, EPUB and Kindle. Book excerpt: This book covers a variety of topics related to kinetic theory in neutral gases and magnetized plasmas, with extensions to other systems such as quantum plasmas and granular flows. A comprehensive presentation is given for the Boltzmann equations and other kinetic equations for a neutral gas, together with the derivations of compressible and incompressible fluid dynamical systems, and their rigorous justification. Several contributions are devoted to collisionless magnetized plasmas. Rigorous results concerning the well-posedness of the Vlasov-Maxwell system are presented. Special interest is devoted to asymptotic regimes where the scales of variation of the electromagnetic field are clearly separated from those associated with the gyromotion of the particles. This volume collects lectures given at the Short Course and Workshop on Kinetic Theory organized at the Fields Institute of Mathematical Sciences in Toronto during the Spring of 2004.

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.

Available in PDF, EPUB and Kindle. Book excerpt: This complete introduction to the use of modern ray tracing techniques in plasma physics describes the powerful mathematical methods generally applicable to vector wave equations in non-uniform media, and clearly demonstrates the application of these methods to simplify and solve important problems in plasma wave theory. Key analytical concepts are carefully introduced as needed, encouraging the development of a visual intuition for the underlying methodology, with more advanced mathematical concepts succinctly explained in the appendices, and supporting Matlab and Raycon code available online. Covering variational principles, covariant formulations, caustics, tunnelling, mode conversion, weak dissipation, wave emission from coherent sources, incoherent wave fields, and collective wave absorption and emission, all within an accessible framework using standard plasma physics notation, this is an invaluable resource for graduate students and researchers in plasma physics.
