Book Description
La region de la tropopause est particulierement importante du point de vue de la dynamique et de la chimie de l'atmosphere. L'objectif est ici de contraindre des simulations numeriques par assimilation d'observations afin d'obtenir une meilleure representation du champ d'ozone dans cette region. Pour cela on utilise le modele de chimie-transport MOCAGE de Meteo-France, et les observations d'ozone du programme europeen MOZAIC. Notre etude a montre que le principal defaut du modele est une tendance a lisser le gradient vertical d'ozone a la tropopause, et que l'assimilation a pour effet de corriger ce defaut. Plusieurs techniques d'assimilation ont ete developpees et comparees. Les meilleurs resultats correspondent a une assimilation dans un systeme de coordonnees epousant le flux. Les analyses produites servent ensuite de base a une etude des echanges d'ozone a la tropopause.

Book Description
The science behind global warming, and its history: how scientists learned to understand the atmosphere, to measure it, to trace its past, and to model its future. Global warming skeptics often fall back on the argument that the scientific case for global warming is all model predictions, nothing but simulation; they warn us that we need to wait for real data, “sound science.” In A Vast Machine Paul Edwards has news for these skeptics: without models, there are no data. Today, no collection of signals or observations—even from satellites, which can “see” the whole planet with a single instrument—becomes global in time and space without passing through a series of data models. Everything we know about the world's climate we know through models. Edwards offers an engaging and innovative history of how scientists learned to understand the atmosphere—to measure it, trace its past, and model its future.

Book Description
This book represents the first multidisciplinary scientific work on a deep volcanic maar lake in comparison with other similar temperate lakes. The syntheses of the main characteristics of Lake Pavin are, for the first time, set in a firmer footing comparative approach, encompassing regional, national, European and international aquatic science contexts. It is a unique lake because of its permanently anoxic monimolimnion, and furthermore, because of its small surface area, its substantially low human influence, and by the fact that it does not have a river inflow. The book reflects the scientific research done on the general limnology, history, origin, volcanology and geological environment as well as on the geochemistry and biogeochemical cycles. Other chapters focus on the biology and microbial ecology whereas the sedimentology and paleolimnology are also given attention. This volume will be of special interest to researchers and advanced students, primarily in the fields of limnology, biogeochemistry, and aquatic ecology.

Book Description
Bourdieu and Literature is a wide-ranging, rigorous and accessible introduction to the relationship between Pierre Bourdieu's work and literary studies. It provides a comprehensive overview and critical assessment of his contributions to literary theory and his thinking about authors and literary works. One of the foremost French intellectuals of the post-war era, Bourdieu has become a standard point of reference in the fields of anthropology, linguistics, art history, cultural studies, politics, and sociology, but his longstanding interest in literature has often been overlooked. This study explores the impact of literature on Bourdieu's intellectual itinerary, and how his literary understanding intersected with his sociological theory and thinking about cultural policy. This is the first full-length study of Bourdieu's work on literature in English, and it provides an invaluable resource for students and scholars of literary studies, cultural theory and sociology.

Book Description
This volume contains the invited papers and a transcript of the final panel discussion in the First Scientific Conference of the International Global Atmospheric Chemistry (lGAC) Project, held in Eilat, Israel from April 18-22, 1993. The conference was hosted by the Israeli Institute for Biological Research (IIBR) and was the 37th in the prestigious OHOLO Conference series in Israel. The conference was devoted to the subject of "Global Atmospheric-Biospheric Chemistry" and was a landmark event in this area. It provided the first comprehensive report of progress under IGAC toward improving our understanding of the chemical and biological processes that determine the changing composition of the earth's atmosphere. This work is an essential component of the comprehensive International Geosphere Biosphere Program (lGBP) devoted to measuring and understanding global changes in the past and present, and predicting the future evolution of our planet. I want to devote this brief foreword to thanking several people who worked especially hard to make the conference a success and who helped to produce this volume as a record of the event. Paul Crutzen, Amram Golombek, Pamela Matson and Henning Rodhe did sterling service on the conference organizing committee. Special thanks go to Amram Golombek and Dr. Cohen, the Director of IIBR, who hosted the event in Israel. Anne Slinn did an excellent job in producing the Abstract book and helping with administrative matters. Alex Pszenny helped capably to critically review the Abstracts.
