Описание: This volume describes the recent developments in the free-radical mediated synthesis and elaboration of heterocycles. The first chapter, dealing with radical cascade processes illustrates the power and the beauty of radical chemistry with some striking examples of total synthesis of complex natural heterocycles. As organic chemists strive towards sustainability, radical chemistry has recently seen major advances and efforts in this direction, including C-H activation of arenes and unactivated alkyl groups. Photochemical activation, for a long time the preferred mode of activation in radical chemistry has also seen an unexpected revival with the advent of visible light metal- and organocatalyzed photoredox processes. A survey of these emerging areas is provided along with the concepts at the origin of these developments. The venerable Minisci reaction allows for direct access to functionalized heterocycles. This process has lately seen an interesting renaissance and is discussed in this volume. Addition of heteroatom-centered radicals onto unsaturated systems constitutes another powerful method to construct heterocycles. Examples of such a strategy are proposed along with the formation of various heterocycles relying on homolytic substitution at sulfur, phosphorus and selenium. Additionally free-radical functionalization of reactive functional groups including isonitriles, isothiocyanates and related unsaturated systems which offer a straightforward route towards useful aromatic and non-aromatic heterocycles are discussed. Finally, as metals are able to trigger single electron transfer both in reductive and oxidative modes this provides another possibility for the synthesis of heterocycles. Significant research efforts have focused on the use of samarium, copper and other metals to access a broad variety of heterocycles in a single pot process, starting from readily available raw material. Examples and mechanistic insights are discussed by experts in this area.

Описание: Humanity’s ability to produce enough food is mostly due to adoption of new methods and technologies by the agricultural industries as they became available. New information, communication and high speed processing and precision agriculture technologies have the potential to transform the agricultural industry. These technologies incorporate radio-frequency and microwave radiation into their systems. This book presents an overview of how these technologies are being used in agricultural systems. The main purpose of the book is to provide a glimpse of what is possible and encourage practitioners in the engineering and agricultural industries to explore how radio-frequency and microwave systems might further enhance the agricultural industry. The authors have extensive experience in agricultural and microwave engineering, instrumentation and communication systems.

Описание: This volume is a must for anyone interested in academic problems and will produce the emotion of recognition in those concerned, and the emotion of surprise in those outside the field.-Los Angeles Times "Professors Caplow and McGee have given scholarly respectability to what many a professor has long suspected: Competition in the academic marketplace is as severe as in the business world. [Their book] might come to have the same function for the professor as Machiavelli's work had for ambitious princes."-Midwest Journal of Political Science The Academic Marketplace is a straightforward, hard-hitting exposu of the American university. Caplow and McGee consider all the working parts of the system and assess their suitability to the professed purpose. Their report on the actualities, myths, and consequences of routines thus amounts to an anatomy of an institution-an anatomy that does not present a pretty picture. We learn, for example, that the chief criteria used in making appointments are prestige and compatibility, not teaching ability. The authors describe the precipitous decline in teaching loads and then explain how this tendency is related to the new seller's market, on the one hand, and to the extravagantly indeterminate structure of the university as an institution, on the other. Not only is the temper judicious, the facts well gathered and competently marshaled, but the expression of results is invariably lucid. In a new introduction, the authors sort out fact from legend and discern trends, they address the validity of their own research methods and the applicability of their original findings to today's academic marketplace. They observe that the essential commodity offered in the academic marketplace is still the same-the mysterious intangible called prestige, by which universities, colleges, departments, disciplines, fields of inquiry, journals, and ultimately faculty candidates are ranked from high to low, and raised up an
