Book excerpt: L'EXTRAPOLATION DES RESULTATS DES EXPERIENCES EN LABORATOIRE SIMULANT LES ATMOSPHERES N2-CH4 CONDUIT A SUPPOSER QUE DE NOMBREUX COMPOSES ORGANIQUES, EN PLUS DE CEUX DEJA DETECTES, SONT PRESENTS DANS L'ATMOSPHERE DE TITAN, LE PLUS GRAND SATELLITE DE SATURNE. IL S'AGIT PRINCIPALEMENT DE NITRILES EN C2-C4, D'HYDROCARBURES EN C2-C6 ET D'AUTRES COMPOSES, TELS LES AZIDES ET LE DIAZOMETHANE, ET LES POLYACETYLENES. ILS POURRAIENT Y ETRE DETECTES PAR RECHERCHE DE LEURS SIGNATURES SUR LES SPECTRES IR DE CETTE PLANETE. CECI NECESSITE DE DISPOSER DES DONNEES SPECTRALES RELATIVES A CES COMPOSES, EN PARTICULIER DES INTENSITES ABSOLUES DES BANDES IR. OR, C'EST RAREMENT LE CAS. NOUS AVONS DEVELOPPE UN PROGRAMME D'ETUDE DES SPECTRES IR DE CES COMPOSES, EN METTANT AU POINT UN SYSTEME EXPERIMENTAL PERMETTANT DE DETERMINER LES INTENSITES DES BANDES INFRAROUGES.

Download or read book Routledge International Handbook of Ignorance Studies written by Matthias Gross and published by Routledge. This book was released on 2015-05-15 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Once treated as the absence of knowledge, ignorance today has become a highly influential topic in its own right, commanding growing attention across the natural and social sciences where a wide range of scholars have begun to explore the social life and political issues involved in the distribution and strategic use of not knowing. The field is growing fast and this handbook reflects this interdisciplinary field of study by drawing contributions from economics, sociology, history, philosophy, cultural studies, anthropology, feminist studies, and related fields in order to serve as a seminal guide to the political, legal and social uses of ignorance in social and political life.

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.

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.

Download or read book Physics Experiments Using PCs written by H.M. Staudenmaier and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physics practical classes form an important part of many scientific and technical courses in higher education. In addition to the older standard experiments, such practicals now generally include a few computer-controlled experiments developed in association with the research groups active in the particular university or college. Since there is relatively little exchange of information between the teaching staff of different institutes, the personal computer, despite its ubiquity, is underexploited in this role as a teaching aid. The present book provides a detailed description of a number of computer-controlled experiments suitable for practical classes. Both the relevant physics and the computational techniques are presented in a form that enables the readers to construct and/or perform the experiment themselves.
