Download or read book Systematics and the Properties of the Lanthanides written by Shyama P. Sinha and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 650 pages. Available in PDF, EPUB and Kindle. Book excerpt: Science is not a mere collection of facts. It is the correlation of facts, the interpretative synthesis of the available knowledge and its application that excite the imagination of a scientist. Even in these days of modern technology, the need for quick and accurate dissemination of new information and current concepts still exists. Conferences and Symposia offer one direct method of communication. The Summer Schools are another approach. The success of a Summer School is mainly due to that human factor and under standing that goes with it and allows for extensive and often time-unrestricted discussions. During the course of the past 20 years, one of the most in tensively studied groups of elements in the Periodic Table is the Lanthanides. In this period, we have increased our knowledge on these once exotic elements, which were once considered to be a part of a lean and hungry industry, many-fold due to the involve ment of scientists from various disciplines. The purpose of our Summer School was to bring a group of ex perts and participants together for the exchange of ideas and in formation in an informal setting and to promote interdisciplinary interactions. Out of many conceivable topics, we selected the following five as the main basis to broaden our knowledge and understanding I) Systematics 2) Structure 3) Electronic and Magnetic Proper ties 4) Spectroscopic Properties and 5) Lanthanide Geochemistry.
Download or read book Chemical Physics of Intercalation written by A.P. Legrand and published by Springer Science & Business Media. This book was released on 2013-12-11 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conjugated polymers suoh as polyaoetylene (CH)x polyphenylene (C6H4)x' poly thiophene (C4H2S)x' etc., which are insulators in their pristine state, can be brought to the metallic state after "doping" with ohemioal speoies whioh oan be either eleotron donors or I aoceptors. . This doping prooess involves a oharge transfer between the dopant moleoule and the polymer ohain whioh are then supposed to be spatially olose to each other. It follows that the meohanism of doping must be oonsidered as an aotual interoalation process, which will greatly affeot the struotural oharacteristios of the starting material, as well as its morphology, as has been observed during the 2 intercalation of graphite and layered compounds . In parallel with these modifioations, the band struoture of the system changes yielding a new set of eleotronio properties. It is evident therefore that the struotural and eleotronio properties are intimately related, and must be studied simultaneously in the same system to give reliable information. A great number of studies have been devoted to the structural and electronic properties of conjugated polymers after a chemical or 2 electrochemical doping process . Most of these concern the properties of the system for a given dopant concentration. With this approach a universal pioture of the polymer/dopant system is very diffioult to obtain, as a comparison between different experiments is very hazardous. On the other hand, only a small number of measurements have been performed during the continuous electroohemioal doping of various polymers.

Download or read book Modeling and Practice of Erosion and Sediment Transport under Change written by Mohamed Meddi and published by MDPI. This book was released on 2019-09-17 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate and anthropogenic changes impact the conditions of erosion and sediment transport in rivers. Rainfall variability and, in many places, the increase of rainfall intensity have a direct impact on rainfall erosivity. Increasing changes in demography have led to the acceleration of land cover changes in natural areas, as well as in cultivated areas, and, sometimes, in degraded areas and desertified landscapes. These anthropogenized landscapes are more sensitive to erosion. On the other hand, the increase in the number of dams in watersheds traps a great portion of sediment fluxes, which do not reach the sea in the same amount, nor at the same quality, with consequences on coastal geomorphodynamics. This book is dedicated to studies on sediment fluxes from continental areas to coastal areas, as well as observation, modeling, and impact analysis at different scales from watershed slopes to the outputs of large river basins. This book is concentrated on a number of keywords: “erosion” and “sediment transport”, “model” and “practice”, and “change”. The keywords are briefly discussed with respect to the relevant literature. The contributions in this book address observations and models based on laboratory and field data, allowing researchers to make use of such resources in practice under changing conditions.

Download or read book Legal Translation and Court Interpreting Ethical Values Quality Competence Training written by Annikki Liimatainen and published by Frank & Timme GmbH. This book was released on 2017-10-24 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: This multidisciplinary volume offers a systematic analysis of translation and interpreting as a means of guaranteeing equality under the law as well as global perspectives in legal translation and interpreting contexts. It offers insights into new research on • language policies and linguistic rights in multilingual communities • the role of the interpreter • accreditation of legal translators and interpreters • translator and interpreter education in multiple countries and • approaches to terms and tools for legal settings. The authors explore familiar problems with a view to developing new approaches to language justice by learning from researchers, trainers, practitioners and policy makers. By offering multiple methods and perspectives covering diverse contexts (e.g. in Austria, Belgium, England, Estonia, Finland, France, Germany, Hong Kong, Ireland, Norway, Poland), this volume is a welcome contribution to legal translation and interpreting studies scholars and practitioners alike, highlighting settings that have received limited attention, such as the linguistic rights of vulnerable populations, as well as practical solutions to methodological and terminological problems.
Download or read book Absorption and Theatricality written by Michael Fried and published by University of Chicago Press. This book was released on 1988-09-15 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: With this widely acclaimed work, Michael Fried revised the way in which eighteenth-century French painting and criticism are viewed and understood. Analyzing paintings produced between 1753 and 1781 and the comments of a number of critics who wrote about them, especially Dennis Diderot, Fried discovers a new emphasis in the art of the time, based not on subject matter or style but on values and effects.

Download or read book Metal Recycling written by and published by UN. This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal recycling is a complex business that is becoming increasingly difficult! Recycling started long ago, when people realized that it was more resource- and cost-efficient than just throwing away the resources and starting all over again. In this report, we discuss how to increase metal-recycling rates - and thus resource efficiency - from both quantity and quality viewpoints. The discussion is based on data about recycling input, and the technological infrastructure and worldwide economic realities of recycling. Decision-makers set increasingly ambitious targets for recycling, but far too much valuable metal today is lost because of the imperfect collection of end-of-life (EoL) products, improper practices, or structural deficiencies within the recycling chain, which hinder achieving our goals of high resource efficiency and resource security, and of better recycling rates.
