Buch. Zustand: Neu. Neuware - - Empowering decision makers by setting the vision for a new approach to energy systems and providing the tools and plans to achieve these objectives - Provides specific and actionable public policy and programme tools - Help solve energy issues worldwide by illustrating how the lessons learned from… the California energy crisis can be used to create an agile energy system for any region in a country Due to the recent catastrophic energy system failures in California along with those in the North-Eastern US and Southern Canada, London, and Italy, the time has come to proclaim the failure of deregulation, privatization or liberalization and propose a new energy system. Agile Energy Systems shows in the first section, how five precipitating forces led to the deregulation debacle in California: (1) major technological changes and commercialization, (2) regulatory needs mismatched to societal adjustments, (3) inadequate and flawed economic models, (4) lack of vision, goals, and planning leading to energy failures, and (5) failure and lack of economic regional development. The second half of the book examines how 'civic market', new economic models, and planning for a sustainable economic environment counteracted these five forces to create an 'agile energy system'. This system is based on renewable energy generation, hybrid or combined and distributed generation technologies. Such an agile system can be a new paradigm for both energy efficiency and reliability for any region or country, in contrast to the brittle centralized energy grid systems created by deregulation. Furthermore, the book overviews how the future of energy systems rests in the emerging 'clean' hydrogen economy.

Buch. Zustand: Neu. Neuware - There is no question that the field of solid state electronics, which essentially began with work at Bell laboratories just after World War II, has had a profound impact on today's Society. What is not nearly so widely known is that advances in the art and science of crystal growth underpin this tec…hnology. Single crystals, once valued only for their beauty, are now found, in one form or another in most electronic, optoelectronic and numerous optical devices. These devices, in turn, have permeated almost every home and village throughout the world. In fact it is hard to imagine what our electronics industry, much less our entire civilization, would have been like if crystal growth scientists and engineers were unable to produce the large, defect free crystals required by device designers. This book brings together two sets of related articles describing advances made in crystal growth science and technology since World War II. One set is from the proceedings of a Symposium held in August 2002 to celebrate 50 years of progress in the field of crystal growth. The second contains articles previously published in the newsletter of the American Association for Crystal Growth in a series called 'Milestones in Crystal Growth'.The first section of this book contains several articles which describe some of the early history of crystal growth prior to the electronics revolution, and upon which modern crystal growth science and technology is based. This is followed by a special article by Prof. Sunagawa which provides some insight into how the successful Japanese crystal growth industry developed. The next section deals with crystal growth fundamentals including concepts of solute distribution, interface kinetics, constitutional supercooling, morphological stability and the growth of dendrites. The following section describes the growth of crystals from melts and solutions, while the final part involves thin film growth by MBE and OMVPE.These articles were written by some of the most famous theorists and crystal growers working in the field. They will provide future research workers with valuable insight into how these pioneering discoveries were made, and show how their own research and future devices will be based upon these developments.

Buch. Zustand: Neu. Neuware - The history of channel catfish farming in the United States serves as a model for the development of pond-based aquaculture industries worldwide. Channel catfish farming is the largest and economically most important aquaculture industry in the United States. In 2003, over 300,000 metric tons (662 m…illion pounds) of channel catfish were processed, representing about half the total United States aquaculture production. Demand for farm-raised catfish is strong, with record processing years in 2002 and 2003. In 22 chapters written by active scientists in the field, Biology and Culture of Channel Catfish comprehensively synthesizes over 30 years of research on this American icon. Throughout the book, fundamental biological aspects of channel catfish are linked to practical culture techniques.Topics include:¿ Latest information on reproductive physiology, genetics, and breeding¿ Comprehensive treatment of catfish nutrition, feeds, and feeding practices¿ Water quality management and pond dynamics¿ In-depth review of immunology in channel catfish¿ Practical information on diseases and health management¿ Techniques for commercial culture, including innovative techniques such as raceways, recirculating systems, and partitioned aquaculture systems¿ Catfish economics and marketing¿ Exploration of environmental concerns, including recommended Best Management Practices.
