Book excerpt: Le présent travail apporte une contribution à la compréhension des mécanismes des transferts combinés de chaleur et de masse en convection naturelle lors de l'évaporation d'un film liquide d'eau d'épaisseur négligeable dans un canal vertical ondulé. L'écoulement est laminaire et bidimensionnel. Les équations régissant le phénomène sont résolues à l'aide d'une méthode aux volumes finis et le traitement du couplage vitesse-pression est réalisé par la méthode de projection. Les influences de la densité de flux de chaleur, de la température ainsi que l'humidité de l'air à l'entrée et la forme de la paroi du canal sur les transferts sont étudiées. Les résultats sont présentés sous la forme de ligne de courant, d'isothermes et d'iso-concentrations.Les simulations numériques effectuées ont permis l'étude détaillée de la structure de l'écoulement ainsi que des champs thermiques et massiques. Nous représentons également, les nombres de Nusselt et de Sherwood.

Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This book has been published by Allenvi (French National Alliance for Environmental Research) to coincide with the 22nd Conference of Parties to the United Nations Framework Convention on Climate Change (COP22) in Marrakesh. It is the outcome of work by academic researchers on both sides of the Mediterranean and provides a remarkable scientific review of the mechanisms of climate change and its impacts on the environment, the economy, health and Mediterranean societies. It will also be valuable in developing responses that draw on “scientific evidence” to address the issues of adaptation, resource conservation, solutions and risk prevention. Reflecting the full complexity of the Mediterranean environment, the book is a major scientific contribution to the climate issue, where various scientific considerations converge to break down the boundaries between disciplines.
