Book excerpt: Le Rayonnement Infrarouge Sortant au sommet de l'atmosphère en ciel clair (OLRc) de la ceinture inter-tropicale est un élément majeur du bilan radiatif terrestre. Afin d'estimer le champ OLRc au-dessus des régions tropicales et subtropicales, nous avons défini un modèle simple à deux paramètres de cette grandeur radiative. Les paramètres de ce modèle sont estimés avec des mesures provenant des satellites METEOSAT pour l'humidité et CERS/AQUA pour la température et le rayonnement. La construction de ce modèle physico-statistique est basée sur une approche analytique classique de l'OLRc que nous avons enrichie à l'aide d'études de sensibilités spectrales de ce flux à la Température de Surface (TS) et à l'Humidité Relative (RH). Les deux variables qui nous permettent de faire une estimation satisfaisante de l'OLRc de nuit sont TS et l'Humidité Relative moyenne de la Troposphère Libre (FTH). Nous étudions alors la sensibilité de l'OLRc aux variabilités de ces champs aux échelles saisonnières et interannuelles. Des zones de forte sensibilité du champ OLRc à la variabilité temporelle de FTH sont identifiées alors que ce champ synthétique est pratiquement insensible à la variabilité de TS. Nous évaluons par la suite la représentation de FTH et TS dans deux modèles de climat effectuant les mêmes expériences de sensibilités sur ces deux champs. Ces modèles représentent de façon satisfaisante la variabilité des champs FTH et TS aux deux échelles temporelles étudiées précédemment. Finalement, nous nous intéressons aux sensibilités de l'OLRc aux échelles climatiques en effectuant des analyses de sensibilités spectrales et verticales sur des profils moyens issus des modèles de climat.

Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.

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.

Book excerpt: The ocean, like our planet as a whole, is undergoing continual change. Oceanography is the interdisciplinary scientific study of ocean behaviour and its relationship with climate, marine resources and the wider environment. This publication seeks to explore the development of oceanographic research aimed at the the non-specialist and to explain key concepts in an accessible manner. Topics discussed include: a brief history of oceanography and major national scientific expeditions; international co-operation programmes; mechanisms linking ocean dynamics with those of the atmosphere and marine ecosystems; climate change; and future developments in oceanographic study.

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.
