Diffusion in metals is an important phenomenon, which has many applications, for example in all kinds of steel and aluminum production, and in alloy formation (technical applications e.g. in superconductivity and semiconductor science). In this book the data on diffusion in metals are shown, both in graphs and in equations.Reliable data on diffusion in metals are required by researchers who try to make sense of results from all kinds of metallurgical experiments, and they are equally needed by theorists and computer modelers. The previous compilation dates from 1990, and measurements r

This first volume, in a new series covering entirely general results in the fields of defects and diffusion, includes abstracts of papers which appeared between the beginning of 2008 and the end of October 2009 (journal availability permitting). This new series replaces the 'general' section which was previously part of each issue of the Metals, Ceramics and Semiconductor retrospective series. As well as 356 abstracts, the volume includes original papers on all of the usual material groups: ""Predicting Diffusion Coefficients from First Principles via Eyring's Reaction Rate Theory"" (Mantina,

"The economies of small developing states tend to be more fragile than those of large ones. This paper examines this issue in a dynamic context by focusing on the impact of the brain drain on North-South trade-related technology diffusion and total factor productivity growth in small and large states in the South. There are three main findings. First, productivity growth increases with North-South trade-related technology diffusion and education and the interaction between the two, and decreases with the brain drain. Second, the impact of North-South trade-related technology diffusion, education, and their interaction on productivity growth in small states is more than three times that for large countries, with the negative impact of the brain drain thus more than three times greater in small than in large states. And third, the greater loss in productivity growth in small states has two brain drain-related causes: a substantially greater sensitivity of productivity growth to the brain drain, and brain drain levels that are more than five times greater in small than in large states.

Diffusion MRI is a magnetic resonance imaging (MRI) method that produces in vivo images of biological tissues weighted with the local microstructural characteristics of water diffusion, providing an effective means of visualizing functional connectivities in the nervous system. This book is the first comprehensive reference promoting the understanding of this rapidly evolving and powerful technology and providing the essential handbook for designing, analyzing or interpreting diffusion MR experiments.The book presents diffusion imaging in the context of well-established, classical experime

Le spectacle vivant s'est structuré depuis les années 1980 en une filière d'activités multiples. Loin d'être une simple crise conjoncturelle. les tensions actuelles qui traversent son système de valeurs et son fonctionnement professionnalisé sont à relier à la mutation économique, culturelle. sociale et politique de notre société. Au travers des projets et organisations souvent peu valorisés, il est possible de mieux comprendre la nature et la complexité de ce qui se joue aujourd'hui dans le spectacle vivant et de fonder un plaidoyer pour une économie politique renouvelée de ce monde de l'art. La norme toujours dominante d'originalité (de l'oeuvre et de l'artiste) est ainsi confrontée aux prémices dune convention d'identité, où les projets artistiques sont plus en lien avec les dynamiques culturelles de construction identitaire des personnes et des groupes. Une conception d'interaction plus soutenue avec les populations et leurs territoires de vie, dans laquelle l'artiste garde sa propre spécificité d'apport et d'engagement. est nécessaire. Une reconfiguration plus mutualiste du spectacle vivant dans son ensemble le serait tout autant.
