Available in PDF, EPUB and Kindle. Book excerpt: It is now time for a comprehensive treatise to look at the whole field of electrochemistry. The present treatise was conceived in 1974, and the earliest invitations to authors for contributions were made in 1975. The completion of the early been delayed by various factors. volumes has There has been no attempt to make each article emphasize the most recent situation at the expense of an overall statement of the modern view. This treatise is not a collection of articles from Recent Advances in Electrochemistry or Modern Aspects of Electrochemistry. It is an attempt at making a mature statement about the present position in the vast area of what is best looked at as a new interdisciplinary field. Texas A & M University J. O'M. Bockris University of Ottawa B. E. Conway Case Western Reserve University Ernest Yeager Texas A & M University Ralph E. White Preface to Volume 4 The science of degradation of materials involves a vast area of science and technology, the economic importance of which rivals that of any other clearly defined area affecting the standard of life. The basis of the corrosion process is the electrochemical charge-transfer reaction, and the center of the subject of the degradation of materials is electrochemical material science.
Download or read book Electrochemical and Optical Techniques for the Study and Monitoring of Metallic Corrosion written by M.G.S Ferreira and published by Springer Science & Business Media. This book was released on 1991-08-31 with total page 732 pages. Available in PDF, EPUB and Kindle. Book excerpt: In spite of considerable efforts over the years to understand and combat materials degradation via corrosion processes, many challenges still remain both in the theoretical understanding of the phenomena and in seeking pratical solutions to the perennial problem. Progress has been slow due to the complexity of the processes and the systems involved. Fortunately, in recent years there has been a renaissance in the development of new electrochemical and optical techniques, as well as advances in instrumentation, which have greatly aided our quest to gain insight into the complex mechanisms involved in metallic corrosion and passivation. Numerous scientific meetings, symposia, and workshops have been held allover the world which attest to the frenzy of activities in corrosion science and technology. However, most of these conferences have dealt mainly with recent research results. There appeared to be a need to assess and disseminate our present state of knowledge in the field as regards measurement techniques, theory, and instrumentation. The present NATO Advanced Study Institute was therefore held in Viana do Castelo, Portugal from July 9 to 21, 1989. The Institute consisted of a series of tutorial lectures, poster sessions, and round-table discussions interspersed evenly over the two-week period. It was attended by 75 participants from several countries representing industry, government and university laboratories.
Download or read book Biodiversity of Malaria in the world written by Manguin Sylvie and published by John Libbey Eurotext. This book was released on 2008-01-01 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the present time, malaria is responsible for a million deaths a year, with 500 million reported cases of the disease and 2.5 billion people at risk of contracting it. The distribution and severity of the disease vary with the causative agents, vectors and environment. Of the 4 possible parasites, only P. falciparum causes fatal forms; the three others have debilitating effects related to frequent disease recurrence and reviviscence. More than 50 species of anophele are involved in the obligatory transmission of the parasite from man to man. Climate, environment and biogeography condition the distribution of anophele species and modulate the intensity of transmission. This is what is known as the biodiversity of malaria. At the present time, more than 90% of P. falciparum malaria deaths occur in tropical Africa where only 10% of the world's population lives. A child dies of malaria every 30 seconds. This continent is home to the most effective vectors and the climate favours transmission. Severe cases also arise in the forested areas of South East Asia, New Guinea and the Amazon region. Throughout the rest of the tropical and subtropical world, the disease caused by P. vivax and/or P. malariae is less serious.
Download or read book valuations nationales des acquis scolaires Volume 5 written by Thomas Kellaghan and published by World Bank Publications. This book was released on 2015-07-13 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'évaluation efficace de la performance des systèmes éducatifs est un élément essentiel de la mise au point de politiques visant à optimiser le développement du capital humain dans le monde. Les cinq manuels de la collection Évaluations nationales des acquis scolaires introduisent les concepts clés des évaluations nationales du niveau de performances des élèves, dont les questions politiques à traiter dans la conception et la mise en 'uvre des évaluations ou le développement d'un test, la conception d'un questionnaire, l'échantillonnage, l'organisation et la mise en 'uvre de la collecte de données, le nettoyage et l'analyse statistique des données, la rédaction de rapports et l'exploitation des résultats pour améliorer la qualité de l'éducation. Qu'apprennent les élèves ' Dans le monde, les gouvernements qui aspirent à améliorer la qualité de l'éducation se tournent vers les évaluations nationales pour obtenir ces informations si précieuses dans les domaines clés des programmes de cours. La capacité à mener des évaluations nationales s'est remarquablement renforcée ces dernières années, mais l'utilisation généralisée des conclusions n'a pas suivi. Ce manuel vise à démontrer la valeur essentielle de ces données et à assister les pays dans l'exploitation des connaissances issues des évaluations nationales. Communiquer et utiliser les résultats d'une évaluation nationale des acquis scolaires recense les principaux facteurs qui affectent l'utilisation des constatations des évaluations nationales. Ceux-ci comprennent le contexte politique dans lequel une évaluation est menée, la nature de l'évaluation (sur la base d'un recensement ou d'un échantillon), les responsabilités de chacun vis-à -vis des résultats, et la qualité des instruments d'évaluation. Le manuel décrit le type d'informations requises dans le rapport principal d'une évaluation nationale, et d'autres moyens de communiquer les conclusions aux publics techniques et non techniques. Il énonce les principes généraux à suivre pour traduire les résultats des évaluations nationales dans le cadre de politiques et de mesures, et examine les procédures spécifiques d'utilisation des données dans l'élaboration de politiques, la gestion de l'éducation, l'enseignement et la promotion de la sensibilisation du public. Les thèmes traités dans ce volume sont de nature à intéresser les responsables des politiques, les équipes pédagogiques, les chercheurs et les professionnels du développement.

Available in PDF, EPUB and Kindle. Book excerpt: For many years it has been recognized that engineering materials that are-tough and ductile can be rendered susceptible to premature fracture through their reaction with the environment. Over 100 years ago, Reynolds associated hydrogen with detrimental effects on the ductility of iron. The "season cracking" of brass has been a known problem for dec ades, but the mechanisms for this stress-corrosion process are only today being elucidated. In more recent times, the mechanical properties of most engineering materials have been shown to be adversely affected by hydrogen embrittlement or stress-corrosion cracking. Early studies of environmental effects on crack growth attempted to identify a unified theory to explain the crack growth behavior of groups of materials in a variety of environments. It is currently understood that there are numerous stress-corrosion processes some of which may be common to several materials, but that the crack growth behavior of a given material is dependent on microstructure, microchemistry, mechanics, surface chemistry, and solution chemistry. Although the mechanism by which various chemical species in the environment may cause cracks to propagate in some materials but not in others is very complex, the net result of all environmentally induced fracture is the reduction in the force and energy associated with the tensile or shear separation of atoms at the crack tip.
