Available in PDF, EPUB and Kindle. Book excerpt: Cette étude est basée sur un modèle de deux grains en contact ayant subi un début de dissolution, et modélisés par deux sphères tronquées pour l'étude du problème mécanique de transfert en solution. Une approche analytique permet de comprendre que la singularité de la contrainte au point de jonction entre la zone de contact et le pore a pour origine la discontinuité du chargement, discontinuité qui se retrouve dans les calculs par éléments finis. La méthode numérique permet de constaterr que l'appoximation consistant à négliger l'énergie libre d'Helmholtz dans la force thermodynamique est valable pour les différentes tailles des grains étudiés. La distribution de la contrainte intergranulaire est moins parabolique quand le grain s'aplatit. La loi de fluage permet de constater que plus la taille du grain diminue, plus le processus de diffusion est rapide : la dissolution est dans ce cas le mécanisme qui gouverne le transfert en solution. L'analyse de stabilité 3D montre que l'instabilité est une onde dont le front est perpendiculaire à la direction de la contrainte effective de compression maximale.

Download or read book Living Systems as Energy Converters written by R. Buvet and published by Elsevier. This book was released on 2013-09-24 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Living Systems as Energy Converters documents the proceedings of the European Conference on Living Systems as Energy Converters held in Pont-a-Mousson, France on October 18-22, 1976. This book is organized into three main topics—energy in biological molecules; biological membranes as energy transducers; and energy in cells, organisms, and populations. In these topics, this compilation specifically discusses the energetic evolution of complex networks of reactions; protein ß-structure and the molecular evolution of biological energy conversion; and structure and function of ATP synthase. The calcium transport in biological membranes; conversion of solar energy into energy-rich phosphate compounds; and energy conservation in photosynthetic electron transport of chloroplasts are also deliberated. This text likewise covers the direct conversion of radiant into electrical energy using plant systems; energy budgets in natural and agricultural ecosystems; and recycling of excess carbon dioxide from fossil energy conversion by plants. This publication is intended for biologists and physical-chemists, including students concerned with the study of living systems as energy converters.

Download or read book Soil Ecotoxicology written by Joseph Tarradellas and published by CRC Press. This book was released on 1996-12-23 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soils are receptacles for a wide range of hazardous chemicals generated by human activities. Whether or not this contamination is deliberate, accurate toxicity assessments are important for health and economic reasons. Soil Ecotoxicology discusses the sources, fate, and transport of hazardous chemicals in soils. The fate (biodegradation and modeling) and the potential impacts of pesticides on soil ecosystems are emphasized, and methodologies for performing toxicity assessments are provided.

Book Synopsis Oceans, Rivers and Lakes: Energy and Substance Transfers at Interfaces by : J.-C. Amiard
Download or read book Oceans, Rivers and Lakes: Energy and Substance Transfers at Interfaces written by J.-C. Amiard and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: An international symposium on `Ocean, River and Lakes: Energy and Substance Transfers at Interfaces' was held in Nantes, France in October 1996. It was the third International Joint Conference on Limnology and Oceanography which brings together specialists of both environments. Considered to be necessary in Europe, this confrontation of two different aspects of common subjects could produce innovative approaches. The main purpose concerns scientific researches relative to the interfaces between various aquatic environment compartments. The principal treated topics are bioavailability and mobility of substances, influence of biotic and abiotic factors on transfers, and fluxes at the interfaces. It is particularly interesting to note the contribution of Limnologists and Oceanographers on the impact of nutrients and pollutants, and flux quantification of river basin inputs. As well as scientists, this book is also of interest to all engineers and consultants involved in teaching and working in aquatic management, restoration and enhancement.

This book was released on 1979 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: Étude théorique de complexes de transfert de charge. Application à l'étude des complexes TCNE-HMB, TCNE-durène, TCNE-naphtalène. Interprétation des résultats qui varient suivant les conditions expérimentales et dépendent des différentes échelles de concentration de la qualité des solutions, de la présence de complexes isomères et de complexes de contact, de l'auto-association et de la présence de complexes trimoléculaires. Dans ce but une étude complète des effets de solvants sur les bandes d'absorption, la complexation, et la formation de complexes soluté-solvant a été faite et elle permet de répartir les solvants étudiés en 2 groupes : dichlorométhane, chloroforme, tétrachlorure de carbone, cyclohexane et hexane considérés comme "inertes" et d'autre part l'éther éthylique, le dioxanne et l'éthanol possédant un pouvoir donneur d'électrons.
