Taschenbuch. Zustand: Neu. Neuware - This text is a summary of basic principles and techniques and is dedicated to all those students who have been told by their mentors, 'Go forth and do two-dimensional gels and have the results on my desk tomorrow. ' No attempt has been made in this text to provide exhaustive lists of references related to basic principles or techniques or to list every com pany or supplier involved in this area of research. Nevertheless, it is hoped that sufficient information is given to help a new investigator or student appreciate the complexities but develop sufficient expertise to carry out these techniques successfully. The discussions are designed to instill in basic science and clinical investigators of all levels of expertise an appreciation of the power of combining a variety of techniques as well as to provide basic insight into the theories, complexities, and problems frequently encountered with electrophoretic and immunochemical meth ods. Bonnie S. Dunbar Houston v Acknowledgments I wish to thank my students and staff for their patience and support throughout the preparation of this text. I would like to acknowledge my appreciation for my extensive discussions with Dr. David Sammons (Uni versity of Arizona) and to Dr. N. L. and Dr. N. G. Anderson and their colleagues (Argonne National Laboratory) for their invaluable advice and suggestions in this area over the years. I thank my research assistant, Ms.…

Buch. Zustand: Neu. Neuware - Most forest tree species were considered recalcitrant a decade ago, but now with the improved in vitro techniques some progress has been made towards culture-of tree species. Micro propagation has been achieved from the juvenile tissues of a number of forest tree species. On the other hand, tissues from most mature trees are still very difficult to grow and differen tiate in vitro. Nevertheless, there has been slow but steady progress in the application of tissue culture technology for culture of tissues, organs, cells and protoplasts of tree species. As compared to most agricultural crops, and herbaceous plant species, trees are a different lot. They have long gene ration cycles. They are highly heterozygous and have a large reservoir of genetic variability. Because of this genetic variability, their response in vitro is also variable. On a single medium, the response of tissues from different trees (genotypes) of a single species may be quite different: some responding by induction of growth and differentiation, while others showing minimal or no growth at all. That makes the somatic cell genetics of woody plants somewhat difficult, but at the same time interesting.…

Buch. Zustand: Neu. Neuware - The second edition of Treating the Criminal Offender was written in an atmosphere of disillusionment and severe criticism of the traditionalist ap proach to treatment. As crime rates soared, the voices of the critics rose in volume and intensity. And so, this third edition-revised toward the end of the decade of the 1980s-embodies the shift in emphasis from rehabilitating the offender to protecting the community. This shift, in our opinion, does not reject the goal of changing the of fender so as to effect his reintegration into society; it uses the strategy of intensive supervision and surveillance only to effect the desired goal. The use of electronics to monitor the offender's whereabouts and the swift ap plication of punitive measures following. the awareness of any violation are extrinsic techniques of control. It is our opinion that for the deep, more lasting changes in behavior, some form of casework, counseling, and/or psy chotherapeutic intervention is essential. We are the cohorts who believe in the effectiveness of such treatment modalities when and if applied to the right target population at the appropriate time.…

Buch. Zustand: Neu. Neuware - The papers collected here are, with three exceptions, those presented at a conference on probability and causation held at the University of California at Irvine on July 15-19, 1985. The exceptions are that David Freedman and Abner Shimony were not able to contribute the papers that they presented to this volume, and that Clark Glymour who was not able to attend the conference did contribute a paper. We would like to thank the National Science Foundation and the School of Humanities of the University of California at Irvine for generous support. WILLIAM HARPER University of Western Ontario BRIAN SKYRMS University of California at Irvine VII INTRODUCTION TO CAUSATION, CHANCE, AND CREDENCE The search for causes is so central to science that it has sometimes been taken as the defining attribute of the scientific enterprise. Yet even after twenty-five centuries of philosophical analysis the meaning of 'cause' is still a matter of controversy, among scientists as well as philosophers. Part of the problem is that the servicable concepts of causation built out of Necessity, Sufficiency, Locality, and Temporal Precedence were constructed for a deterministic world-view which has been obsolete since the advent of quantum theory. A physically credible theory of causation must be, at basis, statistical. And statistical analyses of caus ation may be of interest even when an underlying deterministic theory is assumed, as in classical statistical mechanics.…

Buch. Zustand: Neu. Neuware - Since publication of the first edition of this Handbook, the usage of thenno plastic elastomers (TPEs) has doubled, with a compounded annual growth rate of approximately 9 percent. This second edition summarizes and documents the technological and commercial progress that has given rise to this phenomenal rate of growth. Over the past decade, numerous suppliers and users of ther moplastic elastomers have entered the field, and some have retired from it, a process that almost certainly will continue. This Handbook is intended to serve the broad spectrum of professionals ac tively engaged in the field of thennoplastic elastomers, which has seen a growth rate four to six times that of the rubber and plastics industries. As TPEs embrace both rubber and plastics technology, this book will be useful to rubber and plastics technologists with a broad variety of specific interests. This edition emphasizes commercial practice and practical application rather than research activity. Technology and innovation are stressed, with polymer science functioning as a basis for understanding and communication. We have focused on those TPEs that we consider to be of significant commercial impor tance-the ones now used in the fabrication of useful articles, or which probably will be so used in the foreseeable future.…

Buch. Zustand: Neu. Neuware - Two articles by Lewis Feuer caught my attention in the '40s when 1 was wondering, asa student physicist, about the relations of physics to philosophy and to the world in turmoil. One was his essay on 'The Development of Logical Empiricism' (1941), and the other his critical review of Philipp Frank's biography of Einstein, 'Philosophy and the Theory of Relativity' (1947). How extraordinary it was to find so intelligent, independent, critical, and humane a mind; and furthermore he went further, as I soon realized when I looked for his name on other publications. I recall arguing with myself over his exploration of 'Indeterminacy and Economic Development' (1948), and even more when I read his 'Dialectical Materialism and Soviet Science' (1949). More papers, and then the fascinating, sometimes irritating, always insightful, books. His monograph on Psychoanalysis and Ethics 1955, the beautiful sociological and humanist study of Spinoza and the Rise of Liberalism (1958), his essays on 'The Social Roots of Einstein's Theory of Relativity' (1971) together with the book on Einstein and the Genera tions of Science (1974), the splendid reader from the works of Marx and Engels, Basic Writings on Politics and Philosophy (1959) which was a major text of the '60s, the stimulating essays on the social formation which seems to have been required for a modern scientific movement to develop, set forth most convincingly in The Scientific Intellectual (1963).…

Buch. Zustand: Neu. Neuware - Insects multiply. Destruction reigns. There is dismay, followed by outcry, and demands to Authority. Authority remembers its experts or appoints some: they ought to know. The experts advise a Cure. The Cure can be almost anything: holy water from Mecca, a Government Commis sion, a culture of bacteria, poison, prayers denunciatory or tactful, a new god, a trap, a Pied Piper. The Cures have only one thing in common: with a little patience they always work. They have never been known entirely to fail. Likewise they have never been known to prevent the next outbreak. For the cycle of abundance and scarcity has a rhythm of its own, and the Cures are applied just when the plague of insects is going to abate through its own loss of momentum. -Abridged, with insects in place of voles, from C. Elton, 1924, Voles, Mice and Lemmings, with permission of Oxford University Press This book is an enquiry into the 'natural rhythms' of insect abundance in forested ecosystems and into the forces that give rise to these rhythms. Forests form unique environ ments for such studies because one can find them growing under relatively natural (pri meval) conditions as well as under the domination of human actions. Also, the slow growth and turnover rates of forested ecosystems enable us to investigate insect popula tion dynamics in a plant environment that remains relatively constant or changes only slowly, this in contrast to agricultural systems, where change is often drastic and frequent.…

Buch. Zustand: Neu. Neuware - Two-phase flow heat exchangers are vital components of systems for power generation, chemical processing, and thermal environment control. The art and science of the design of such heat exchangers have advanced considerably in recent years. This is due to better understanding of the fundamentals of two-phase flow and heat transfer in simple geometries, greater appreciation of these processes in complex goemetries, and enhanced predictive capability through use of complex computer codes. The subject is clearly of great fundamental and practical importance. The NATO ASIan Thermal-Hydraulic Fundamentals and Design of Two-Phase Flow Heat Exchangers was held in Povoa de Varzim (near Porto), Portugal, July 6-17, 1987. participating in the organization of' the ASI were the Department of Mechanical Engineering and the Clean Energy Research Institute, University of Miami; Universidade do Porto; and the Department of Mechanical Engineering, Aeronautical Eng ineer ing, and Mechanics, Rensselaer Polytechnic Institute. The ASI was arranged primarily as a high-level teaching activity by experts representing both academic and industrial viewpoints. The program included the presentation of invited lectures, a limited number of related technical papers and discussion sessions.…
