Buch. Etat : Neu. Neuware - Circuit simulation has been a topic of great interest to the integrated circuit design community for many years. It is a difficult, and interesting, problem be cause circuit simulators are very heavily used, consuming thousands of computer hours every year, and therefore the algorithms must be very efficient. In addi tion, circuit simulators are heavily relied upon, with millions of dollars being gambled on their accuracy, and therefore the algorithms must be very robust. At the University of California, Berkeley, a great deal of research has been devoted to the study of both the numerical properties and the efficient imple mentation of circuit simulation algorithms. Research efforts have led to several programs, starting with CANCER in the 1960's and the enormously successful SPICE program in the early 1970's, to MOTIS-C, SPLICE, and RELAX in the late 1970's, and finally to SPLICE2 and RELAX2 in the 1980's. Our primary goal in writing this book was to present some of the results of our current research on the application of relaxation algorithms to circuit simu lation. As we began, we realized that a large body of mathematical and exper imental results had been amassed over the past twenty years by graduate students, professors, and industry researchers working on circuit simulation. It became a secondary goal to try to find an organization of this mass of material that was mathematically rigorous, had practical relevance, and still retained the natural intuitive simplicity of the circuit simulation subject.

Buch. Etat : Neu. Neuware - In 1628 William Harvey published his discovery of the existence of the microcirculation which he deduced from careful anatomical and physiological study. Thirty-three years later, Malpighi confirmed the presence of capillaries through direct microscopical observation. Subsequent scientific advance has been slow, and in view of the fact that microvascular in the genesis and expression of many pathophysiology may be implicated diseases, our know ledge of human microvascular function is surprisingly limited. This ignorance attests to the difficulty of studying something that is both minute and inaccessible without disturbing the quantity that is being measured. In the last fifteen years, however, direct techniques have been developed for studying human microvascular pressure, flow and permeability. These methods have provided new insights into human microvascular function in health and disease. At the same time there has been a steady growth of new indirect techniques based on a w ide range of physical principles that reflect some or other aspect of microvascular function.

Buch. Etat : Neu. Neuware - During the 25 years since acute coronary care was focused into Coronary Care Units there have been three major Phases: I. prevention of death caused by arrhythmias; II. prevention of death due to myocardial failure; and III. limitation of infarct size. In the latter two Phases, there has been infringement upon the time honored concept of a prolonged period of rest for the patient in general and the heart in particular to minimize myocardial metabolic demands. During the second Phase of coronary care, patients with myocardial failure received aggressive measures to increase cardiac work via increase in preload, decrease in afterload, and direct increase in inotropy. It was believed that true cardiogenic shock was so irreversible that it should be prevented by vigorous efforts to improve the cardiac output despite the risk of extending the area of ischemic myocardium. However, Phase II produced minimal overall reduction in mortality. In the initial part of Phase III, myocardial infarct (MI) size limitation was attempted by reducing myocardial metabolic demands via either beta adrenergic or calcium channel blocking agents. We are currently several years into the second part of Phase III of coronary care where the principle means of limiting MI size is restoration of coronary blood flow.

Buch. Etat : Neu. Neuware - The methodology of drug development has been the subject of extensive dis cussion by a relatively small group of individuals in industry and government who have been intimately concerned with the identification and study of new anticancer drugs. The Chemotherapy Program of the National Cancer In stitute has represented the major focus of initial efforts in drug development, as summarized in the historical perspective presented in chapter 1 and its references. It is no coincidence that the Chemotherapy Program was the origin of the Division of Cancer Treatment, a government entity that has had a pivotal role in the growth of clinical oncology. In an analogous fashion this book presents the methodology employed in the clinical study of anticancer drugs within the broad context of cancer treatment. The research orientation promulgated in the study of new drugs is a central theme in most oncolo gists' approach to the clinical problem of cancer. Therefore, we hope that this book will introduce readers to treatment research in clinical oncology. For the oncologist, the clinical evaluation of antitumor therapy is both part of the day-to-day management of specific patients and the critical considera tion of developing therapeutic alternatives. For physicians in other fields of medicine it is important to acquaint themselves with the basic tools of the oncologist. For people without medical training, including patients who might be interested in treatment research, many of the chapters may be overly technical.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book is about human behavior and, more particularly, about a class of human behaviors-those behaviors by people that have themselves as the object of their behaviors. These self-referent behaviors are social in nature in the sense that in large measure, they are the outcomes of pervasive social processes and are themselves major influences on social outcomes. As such, self-referent behaviors have the potential to be sig nificant organizing constructs in the study of the broader field of social psychology. In any case, they are regarded here as of intrinsic interest and are the focus of this volume. Four broad categories of self-referent behaviors are considered with regard to their social bases and conse quences as these are revealed in the social psychological and sociological literature. With appropriate discriminations made within each group ing, the four categories are: self-conceiving, self-evaluating, self-feeling, and self-protective-self-enhancing responses. Following a consideration of the social antecedents and consequences of each category of self referent behaviors, I present a final summary statement that outlines a theoretical model of the additive and interactive social influences on and consequences of the mutually influential self-referent behaviors. The outline of the theoretical model reflects my synthesis of the apparently relevant theoretical and empirical literature and is intended to function as a framework for the orderly incorporation of new theoretical asser tions and more or less apparently relevant empirical associations. 224 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume is intended to address contemporary aspects of child rearing in the home and the school, as well as major dimensions of inter face between the home and the school. The authors of these chapters have used varying styles and approaches, and the range of perspectives is very broad and inclusive. An essential notion integrating all chapters is that child rearing is a human ecological concern of dominant importance for the home, the school, and the community during the 1980's and that this will continue to be true in the future. This volume is intended to be useful as a reference book, as a text, for researchers and for policy-makers. It is hoped that the volume also will be of use to parents, teachers, school administrators, child-care workers and others who are interested in child nurturance. The editors wish to extend appreciation to many individuals who made this effort possible. Our colleagues, Hiram Fitzgerald and Marjorie Kostelnik, have been most helpful and encouraging. We thank them for their patience, support, and invaluable editorial assistance during the production of the camera-ready copy of the volume. We also thank Barbara Taylor for her assistance in typing the chapters, and Carrie DeMyers for typing the camera-ready copy. Carrie's good-nature and posi tive outlook helped to smooth over the many frustrations inherent in the assembly and production of anthologies such as this one. 248 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Any branch of biology depends for its progress on the development of new concepts and to a lesser, but sometimes crucial, extent on the elimination of erroneous notions. Understanding the roles of bacteria required first the observation that such minute creatures existed, and subsequently the exper imental demonstrations that their presence was necessary for the occurrence of particular phenomena. In this first volume, the authors review the development of scientific understanding of the role of microbes as agents of diverse natural processes. Notably absent is a separate review of the history of microbes as agents of disease, a his tory available in many other publications. Regrettably absent is a review of the his tory of microbes as agents of inorganic transformations, a serious omission that resulted from the illness of the prospective author late in the preparation of this volume. The topic will of course be treated in later volumes, although not predominantly in a historical manner. Otherwise, the emphasis in this volume is on the history of understanding interrelationships between modes of bacterial existence and the inanimate environment. These relationships were established long be fore multicellular, differentiated or ganisms appeared as potential microbial habitats, and their recognition and elucidation contributed greatly to the widened appreciation of bacterial di versity and the importance of these simpler creatures to the physiochemical conditions of the biosphere.' 408 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -There can be few elements with a biochemistry as coherent as that of sulfur. This important element is crucial to myriad aspects of metabo lism, catalysis, and structure. The plurality of functions in which sulfur is involved derives squarely from the numerous oxidation states in which it may exist, some having great stability, some being capable of ready redox interconversions, and yet others having great instability. As a result, the flux of sulfur from the geosphere through the various kingdoms of life leaves few biochemical processes unaffected. Although there are large gaps in the fabric of our basic knowledge of sulfur biochemistry, it is sufficiently framed to allow a unified and organized story, a story which many of the best-known names in bio chemistry have helped to write. It has been both a task and a privilege to try and summarize this story, one that is enormous, complex, fast moving, still developing and, above all, exciting. I suppose that no mo nographer of such a vast subject could be satisfied with his efforts. It is unfortunately probable that in attempting this task I have made as many errors as a Stilton cheese has blue streaks, and as many omissions as a Swiss cheese has holes. Perfection is not to be achieved in a monograph. Inasmuch as I have succeeded, the credit belongs to those whose efforts gave us the knowledge we have. Where I have failed, the fault is only mine. 464 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Developments in electronic hardware, particularly microprocessors and solid-state cameras, have resulted in a vast explosion in the range and variety of applications to which intelligent processing may be applied to yield cost-effective automation. Typical examples include automated visual inspection and repetitive assembly. The technology required is recent and specialized, and is thus not widely known. VISION AND INFORMATION PROCESSING FOR AUTOMATION has arisen from a short course given by the authors to introduce potential users to the technology. Its content is a development and extension of material presented in the course. The objective of the book is to introduce readers to modern concepts and techniques basic to intelligent automation, and explain how these are applied to prac tical problems. Its emphasis is on machine vision. Intelligent instrumentation is concerned with processing infor mation, and an appreciation of the nature of information is essential in configuring instrumentation to handle it effiCiently. An understand ing of the fundamental principles of efficient computation and of the way in which machines make decisions is vital for the same reasons. Selection of appropriate sensing (e.g., camera type and configuration), of illumination, of hardware for processing (microchip or parallel processor ) to give most effective information flow, and of the most appropriate processing algorithms is critical in obtaining an optimal solution. Analysis of performance, to demonstrate that requirements have been met, and to identify the causes if they have not, is also important. All of these topics are covered in this volume. 502 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book developed from a course on finite fields I gave at the University of Illinois at Urbana-Champaign in the Spring semester of 1979. The course was taught at the request of an exceptional group of graduate students (includ ing Anselm Blumer, Fred Garber, Evaggelos Geraniotis, Jim Lehnert, Wayne Stark, and Mark Wallace) who had just taken a course on coding theory from me. The theory of finite fields is the mathematical foundation of algebraic coding theory, but in coding theory courses there is never much time to give more than a 'Volkswagen' treatment of them. But my 1979 students wanted a 'Cadillac' treatment, and this book differs very little from the course I gave in response. Since 1979 I have used a subset of my course notes (correspond ing roughly to Chapters 1-6) as the text for my 'Volkswagen' treatment of finite fields whenever I teach coding theory. There is, ironically, no coding theory anywhere in the book! If this book had a longer title it would be 'Finite fields, mostly of char acteristic 2, for engineering and computer science applications. ' It certainly does not pretend to cover the general theory of finite fields in the profound depth that the recent book of Lidl and Neidereitter (see the Bibliography) does. 222 pp. Englisch.
