This book was released on 2012-12-06 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photonics, the counterpart of electronics, involves the usage of Photons instead of electrons to process information and perform various switching operations. Photonics is projected to be the technology of the future because of the gain in speed, processing and interconnectivity of network. Nonlinear optical processes will play the key role in photonics Where they can be used for frequency conversion, optical switching and modulation. Organic molecules and polymers have emerged as a new class of highly promising nonlinear optical materials Which has captured the attention of scientists world wide. The organic systems offer the advantage of large nonresonant nonlinearities derived from the 1T electrons contribution, femtosecond response time and the flexibility to modify their molecular structures. In addition, organic polymers can easily be fabricated in various device structures compatible with the fiber-optics communication system. The area of nonlinear optics of organic molecules and polymers offers exciting opportunities for both fundamental research and technologic development. It is truly an interdisciplinary area. This proceeding is the outcome of the first NATO Advanced Research WOrkshop in this highly important area. The objective of the workshop was to provide a forum for scientists of varying background from both universities and industries to come together and interface their expertize. The scope of the workshop was multidisciplinary with active participations from Chemists, physicists, engineers and materials scientists from many countries.

Download or read book Against Expression written by Craig Dworkin and published by Northwestern University Press. This book was released on 2011-01-17 with total page 657 pages. Available in PDF, EPUB and Kindle. Book excerpt: Charles Bernstein has described conceptual "poetry pregnant with thought." Against Expression, the premier anthology of conceptual writing, presents work that is by turns thoughtful, funny, provocative, and disturbing. Editors Craig Dworkin and Kenneth Goldsmith chart the trajectory of the conceptual aesthetic from early precursors such as Samuel Beckett and Marcel Duchamp through major avant-garde groups of the past century, including Dada, Oulipo, Fluxus, and language poetry, to name just a few. The works of more than a hundred writers from Aasprong to Zykov demonstrate a remarkable variety of new ways of thinking about the nature of texts, information, and art, using found, appropriated, and randomly generated texts to explore the possibilities of non-expressive language. --Book Jacket.

Download or read book Corrosion Guide written by E. Rabald and published by Elsevier. This book was released on 2012-12-02 with total page 937 pages. Available in PDF, EPUB and Kindle. Book excerpt: Corrosion Guide presents a list of corrosive agents and the trade names of materials, including metallic and non-metallic materials as well as alloys. The book provides guidance in using the tabulated information. This reference also lists relevant publications that deal with the properties of various materials. This new edition provides more data that are not included in the previous edition. The former edition fails to present enough information as the provided properties of the corrosive agents varies and other data are not available. The release aims to minimize missing information about the subject matter. This compilation of tabulated data provides description of each group of corrosive agents. Elements and compounds under each group are listed, along with their properties such as room temperature, corrosion rate, and composition. The list of trade names of materials also describes the composition of each material. The information contained in this book is intended to help practicing engineers deal with corrosion.

Download or read book Physics and Chemistry of Finite Systems From Clusters to Crystals written by Peru Jena and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 1414 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent innovations in experimental techniques such as molecular and cluster beam epitaxy, supersonic jet expansion, matrix isolation and chemical synthesis are increasingly enabling researchers to produce materials by design and with atomic dimension. These materials constrained by sire, shape, and symmetry range from clusters containing as few as two atoms to nanoscale materials consisting of thousands of atoms. They possess unique structuraI, electronic, magnetic and optical properties that depend strongly on their size and geometry. The availability of these materials raises many fundamental questions as weIl as technological possibilities. From the academic viewpoint, the most pertinent question concerns the evolution of the atomic and electronic structure of the system as it grows from micro clusters to crystals. At what stage, for example, does the cluster look as if it is a fragment of the corresponding crystal. How do electrons forming bonds in micro-clusters transform to bands in solids? How do the size dependent properties change from discrete quantum conditions, as in clusters, to boundary constrained bulk conditions, as in nanoscale materials, to bulk conditions insensitive to boundaries? How do the criteria of classification have to be changed as one goes from one size domain to another? Potential for high technological applications also seem to be endless. Clusters of otherwise non-magnetic materials exhibit magnetic behavior when constrained by size, shape, and dimension. NanoscaIe metal particles exhibit non-linear opticaI properties and increased mechanical strength. SimiIarly, materials made from nanoscale ceramic particIes possess plastic behavior.

Download or read book The Protective Arm of the Renin Angiotensin System RAS written by Thomas Unger and published by Academic Press. This book was released on 2015-04-18 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Protective Arm of the Renin Angiotensin System: Functional Aspects and Therapeutic Implications is the first comprehensive publication to signal the protective role of a distinct part of the renin–angiotensin system (RAS), providing readers with early insight into a complex system which will become of major medical importance in the near future. Focusing on recent research, The Protective Arm of the Renin Angiotensin System presents a host of new experimental studies on specific components of the RAS, namely angiotensin AT2 receptors (AT2R), the angiotensin (1–7) peptide with its receptor Mas, and the enzyme ACE 2, which exert significant beneficial, health-promoting actions by counterbalancing the well-known harmful arm of the RAS with its classical angiotensin AT1 receptor. This innovative concept of the protective arm of the RAS, examined in this reference, represents an indispensable background and will be a strong support for biomedical students, researchers, cardiologists, surgeons, nephrologists, diabetologists, and endocrinologists, as well as any other physician or researcher concerned with RAS physiology, pathophysiology and clinical implications. - Provides a complete understanding of the protective side of the Renin Angiotensin System (RAS) involving angiotensin AT2 receptor, ACE2, and Ang(1-7)/Mas receptor - Combines the knowledge of editors who pioneered research on the protective renin angiotensin system including; Dr. Thomas Unger, one of the founders of AT2 receptor research; Dr. Ulrike M. Steckelings, who contributed significantly to first preclinical studies with a novel specific AT2-agonist, and Dr. Robson Santos who pioneered research on angiotensin-(1-7) and its receptor Mas. - Shows that the protective RAS axes are able to ameliorate the course of several cardiovascular, renal, metabolic and neurological diseases - Provides the basis for the understanding of a novel therapeutic approach to stimulate components of the protective arm of the RAS.

Download or read book Plant Ecology written by Paul A. Keddy and published by Cambridge University Press. This book was released on 2017-04-17 with total page 629 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presenting a global and interdisciplinary approach to plant ecology, this much-awaited new edition of the book Plants and Vegetation integrates classical themes with the latest ideas, models, and data. Keddy draws on extensive teaching experience to bring the field to life, guiding students through essential concepts with numerous real-world examples and full-colour illustrations throughout. The chapters begin by presenting the wider picture of the origin of plants and their impact on the Earth, before exploring the search for global patterns in plants and vegetation. Chapters on resources, stress, competition, herbivory, and mutualism explore causation, and a concluding chapter on conservation addresses the concern that one-third of all plant species are at risk of extinction. The scope of this edition is broadened further by a new chapter on population ecology, along with extensive examples including South African deserts, the Guyana Highlands of South America, Himalayan forests and arctic alpine environments.
