Book excerpt: LORS DES ERUPTIONS SOLAIRES, LES OBSERVATIONS MONTRENT PARFOIS LE MAXIMUM DCES EMISSIONS GAMMA ET X DE HAUTE ENERGIE RETARDE PAR RAPPORT A CELUI DES X DE PLUS BASSE ENERGIE. DEUX INTERPRETATIONS SONT PROPOSEES: ACCELERATION RETARDEE DES IONS (RESPONSABLES DES RAIES GAMMA) ET DES ELECTRONS DE HAUTE ENERGIE (RESPONSABLES DES RAYONS X) PAR RAPPORT AUX ELECTRONS DE BASSE ENERGIE OU RESULTAT D'UN PIEGEAGE PARTIEL ET/OU D'UNE PROPAGATION DES PARTICULES DE LA REGION D'ACCELERATION AUX SITES D'EMISSION. DANS CE DERNIER CONTEXTE, CETTE THESE PRESENTE UN MODELE DECRIVANT LE TRANSPORT EN FONCTION DU TEMPS DES IONS ACCELERES EN TENANT COMPTE DE LEURS INTERACTIONS AVEC LE MILIEU AMBIANT. L'EVOLUTION TEMPORELLE DE QUELQUES RAIES GAMMA PROMPTES PRODUITES PAR LES PROTONS EST PREDITE, ET L'EVOLUTION TEMPORELLE RELATIVE ENTRE L'EMISSION GAMMA ET L'EMISSION X DUR PRODUITE PAR DES ELECTRONS INJECTES SIMULTANEMENT DANS LA MEME STRUCTURE EST EXAMINEE. LES RESULTATS QUALITATIFS MONTRENT QUE LES RETARDS OBSERVES PEUVENT ETRE INTERPRETES DANS CE CONTEXTE. L'APPLICATION DE CE MODELE A DES EVENEMENTS PRESENTANT DES RETARDS X-GAMMA DONNE UN BON ACCORD ENTRE LES EVOLUTIONS TEMPORELLES PREDITES ET OBSERVEES DES FLUX X ET GAMMA, ET PERMET AINSI DE DETERMINER LES CARACTERISTIQUES DES PARTICULES ACCELEREES ET DU MILIEU AMBIANT. CE TRAVAIL MONTRE QUE LES EFFETS DU TRANSPORT DES PARTICULES CONTRIBUENT EN GRANDE PARTIE A L'EXISTENCE OU NON DES RETARDS ET QU'IL EST NECESSAIRE D'EN TENIR COMPTE DANS L'ETUDE DE L'EVOLUTION TEMPORELLE DES FLUX X ET GAMMA

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: 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.

Book excerpt: In 1969 the U.S. Air Force issued a statement that read' "No UFO reported, investigated and evaluated by the Air Force was ever an indication of threat to our national security." This statement is patently false. It has been proven untrue by the testimony of many military officers and airmen and documentation of incidents involving UFOs and nuclear weapons, testimonies of which the U.S. Air Force was fully aware. Unidentified details many of these testimonies, some for the first time. As partial justification for its position, the Air Force cites a University of Colorado study that was contracted and paid for by federal funds. Unidentified reveals how this study was actually just another part of the plan to cover up the reality of the UFO phenomenon. For the first time, Unidentified publishes evidence that the investigators for the Colorado study knew about the UFO-related missile shutdown incidents but did not investigate them or include them in their final report.

Book excerpt: An Apollo 11 astronaut and the Nebula Award–nominated author of Directive 51 present a novel that “conveys the wonder and promise of space” (Publishers Weekly). Born the year of the Moon landing, Chris Terence spends his life fighting to return humanity to that pinnacle. An engineering student with dreams of spaceflight, he finds upon graduation that the United States no longer has need for astronauts. Years of bureaucratic meddling have reduced the space program to a shell of itself, and it will take the greatest scientific find in history to send humanity skyward once more. After years battling budget hawks, Chris finally gets his chance to walk on the Moon. While there, he finds evidence of an ancient alien civilization, the Tiberians, who visited Earth’s satellite eight thousand years before. Understanding what happened to those long-forgotten travelers will define the lives of Chris and his son, as they fight against all odds to unlock the secrets of the universe. “The collaboration of the first man to pilot a moon lander (Aldrin) with a major voice in contemporary science fiction (Barnes) has produced a fascinating chronicle of man’s first encounter with alien intelligence” (Booklist).
