This three-volume set represents the first comprehensive coverage of the rapidly expanding field of Lewis base catalysis that has attracted enormous attention in recent years. Lewis base catalysis is a conceptually novel paradigm that encompasses an extremely wide variety of preparatively useful transformations and is particularly effective for enantioselectively constructing new stereogenic centers. As electron-pair donors, Lewis bases can influence the rate and stereochemical course of myriad synthetic organic reactions. The book presents the conceptual/mechanistic principles that underlie Lewis base catalysis, and then builds upon that foundation with a thorough presentation of many different reaction types. And last but not least, the editors, Prof. Edwin Vedejs and Prof. Scott E. Denmark, are without doubt the leaders in this emerging field and have compiled high quality contributions from an impressive collection of international experts.
A glass of wine at dinner and a flatter stomach in 14 days? Yes girls, it can be done! The Viva Mayr Diet is the savvy diet for people in the real world who want to get a bikini body and revamp their health with ease. It's based on the world-famous Viva Mayr spa clinic in Austria, the hottest health and weight loss destination in Europe.
This study reproduces one "Report of Meetings" & six "Bulletins" from the Committee on Common Problems of Genetics, Paleontology, & Systematics. This Committee operated as an administrative unit of the National Research Council, part of the U.S. Nat. Acad. of Science. It was launched in 1943, blossomed for two years, then served as a cornerstone for other cooperative projects. The Committee provided a crucial foothold for those seeking a synthetics view of evolution in 1940s America. These forgotten documents show the Committee at work: building coalitions, defining priorities, & negotiating a common vision. They also show factions within the Committee competing for the leadership of this emerging community. Photo.
This book is about evolutionary theory. It deals with aspects of its history to focus upon explanatory structures at work in the various forms of evolutionary theory - as such this is also a work of philosophy. Its focus lies on recent debates about the Modern Synthesis and what might be lacking in that synthesis. These claims have been most clearly made by those calling for an Extended Evolutionary Synthesis. The author argues that the difference between these two positions is the consequence of two things. First, whether evolution is a considered as solely a population level phenomenon or also a theory of form. Second, the use of information concepts. In this book Darwinian evolution is po...
This newly revised and updated reference presents sensible approaches to the design, selection, and usage of high-voltage circuit breakers-highlighting compliance issues concerning new and aging equipment to the evolving standards set forth by the American National Standards Institute and the International Electrotechnical Commission. This edition features the latest advances in mechanical and dielectric design and application from a simplified qualitative perspective. High Voltage Circuit Breakers: Design and Applications features new material on contact resistance, insulating film coatings, and fretting; temperature at the point of contact; short-time heating of copper; erosion and electromagnetic forces on contacts; closing speed and circuit breaker requirements; "weld" break and contact bounce; factors influencing dielectric strength; air, SF6, vacuum, and solid insulation; and dielectric loss and partial discharges, and includes updated chapters on capacitance switching; switching series and shunt reactors; temporary overvoltages; and the benefits of condition monitoring.
The chemistry of transition metal carbyne complexes has become a highly attractive field during the past twenty years. In recent years its application to aspects of catalysis and metathesis has gained considerable interest from inorganic as well as organic chemists. In addition, organic synthesis by means of metal carbon multiple bond reagents offers the most sophisticated technology currently available. In consideration of these developments some of Professor E. O. Fischer's former coworkers and colleagues felt obliged to orga nize this NATO Advanced Research Workshop on Transition Metal Carbyne Complexes in the Bavarian Alps. They have been encouraged by the fact that most of the distingui...

Hardbound. As its title suggests, this book is intended to give exhaustive information on virus infections and diseases occurring in ruminants. Each virus and corresponding disease is described in a separate chapter, and the chapters are ordered according to current virus classification. Contributing authors are experts on the virus and disease they describe. Where necessary, the text is accompanied by tables and pictures. The accent is placed on diagnosis of the disease by clinical observations including epizootological data. There is also a description of the laboratory procedures of diagnostic virology, and suggestions concerning control measures (e.g. vaccination and/or eradication policy).This book should prove indispensable to: the practising veterinarian, by facilitating recognition of a viral disease, and giving advice on collecting appropriate specimens for laboratory investigation; the veterinary virologist by aiding the choice of appropriate
