Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This is the first volume of an annual monographic series devoted to the diverse aspects of electronics packaging technology. Each book is to be based on that year's presentations at the annual Electronics Packaging Symposium, which is run at the State University of New York at Binghamton by the Continuing Education Division of the T. J. Watson School of Engineering, Applied Science and Technology in cooperation with local professional societies (IEEE, ASME, SME, IEPS) and UnlPEG (University-Industry Partnership for Economic Growth. ) Electronics Packaging has been receiving significant visibility in recent years as it has become obvious that the near-future limitations to the continued development of high performance electronic chips will arise from technological problems in their packaging. The two most obvious of these are the escalating difficulties of removing Joule heat from circuits packed ever more closely together, and the problem of providing more and more electrical contacts to smaller and smaller packages. As recognition of these problems has developed, organizations such as NSF, SRC and MCC have joined with industry in calling for increased research effort in the area. The Materials Research Society and other professional scientific groups have introduced Electronics Packaging sessions into their conference programs, and the International Electronics Packaging Society (IEPS) is expanding rapidly. The field is inherently multi-disciplinary, incorporating several of the traditional sub-areas of Mechanical and Electrical Engineering, Physics and Chemistry. 360 pp. Englisch.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The manifold forms and uses of glass are becoming increasing ly important in science, industry, and our personal lives. This constantly improving material interests a range of people extending beyond the relatively small number of glass experts. Naturally, questions arise as a result of this widespread interest. For this reason, we have heeded the publisher's suggestion to develop a glass primer which answers many questions and explains much of the terminology. The bases for this Schott Guide to Glass were the lecture manuscript, 'Glass Science for Designers' by Prof. Dr.-Ing. Heinz Pfaender, and the Schott pamphlet, Concepts of Technical Glass from A to Z. The manuscript which evolved into this book was written by members of the Schott scientific staff. We thank all those involved in producing this reference work. The Schott Guide to Glass will give experts, interested amateurs, and those who work with glass a glimpse into the diversity of this fascinating material. Mainz, Germany, September 1995 The editor Schott Glaswerke Introduction Glass is possibly the oldest man-made material, used without interruption since the beginning of recorded history. Unlike bronze or iron, however, it has not lent its name to any historical epoch. Still, the use of glass from hand-blown goblets to electronic components has grown with the rise of the industrial era and greatly affects present life. Glassmaking has always been one of the few truly integrated manufacturing processes where native minerals are transformed into an incredible variety of finished products within a single factory. 224 pp. Englisch.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -It is often possible to identify fragments of plants by studying their microscopical characteristics. The recognition of a single feature very rarely establishes the plant's identity; more often, it is necessary to recognize a unique combination of characteris tics. For plant identification, the most valuable characteristics are those least likely to be affected by changes in environment; if the feature is uncommon as well as stable, it is even more useful. Good descriptions of the anatomy of plants are invaluable. For example, The Identifi cation of Hardwoods (Brazier and Franklin, 1961), together with its punched card key, is an excellent book which is useful in practice. Characters describing the sc1erenchyma account for only three places in this key. Using only these characters, it would be impossible to identify a timber. Is it possible then, to identify a species given only sc1erenchyma in the form of a commercial fibre If it is possible, it is not easy. Although, for many purposes, plant fibres are being replaced by man-made fibres, vegetable fibres are still used, particularly in sacking and cordage and in some indus trial materials. Articles which must be examined in a forensic science laboratory are not always of recent manufacture and archaeologists and historians are interested in older materials. Therefore, it is still necessary for many workers to identify the plant species from which fibres have been extracted. 116 pp. Englisch.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In the second century, Galen recognized that nerve and muscle were functionally inseparable since contraction of muscle occurred only if the nerves supplying that muscle were intact. He therefore concluded that the shortening of a muscle was controlled by the central nervous sytem while the extension of a muscle could occur in the absence of innervation. Nerves, he thought, were the means of transport for animal spirits to the muscles; the way in which animal spirits may bring about contraction dominated the study of muscle physiology from that time until the historical discovery of Galvani that muscle could be stimulated electrically and that nerve and muscle were themselves a source of electrical energy. It is now well known that nerves conduct electrically and that transmission from nerve to striated muscle is mediated by the chemical which is liberated from nerve terminals onto the muscle membrane. In vertebrates this chemical is acetylcholine (ACh). Thus the concept of spirits that are released from nerves and control muscle contraction directly, is no longer tenable. Nevertheless the concept of 'substances' transported down nerv~s which directly control many aspects of muscle has not been abandoned, and has in fact been frequently reinvoked to account for the long-term regula tion of many characteristics of muscle (see review by Gutmann, 1976) and for the maintenance of its structural integrity. 248 pp. Englisch.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Joseph F. White has studied, worked, and taught in all aspects of microwave semiconductor materials, control diodes, and circuit applications. He is thoroughly grounded in the physics and math ematics of the field, but has primarily the engineer's viewpoint, combining basic knowledge with experience and ingenuity to gen erate practical designs under constraints of required performance and costs of development and production. As a result of his teach ing experience and numerous technical papers and oral presenta tions, he has developed a clear, well-organized writing style that makes this book easy to use as a self-teaching text, a reference volume, and a design handbook. Dr. White believes that an engineer must have a good understand ing of semiconductor physics, a thorough knowledge of microwave circuit theory, at least an elementary acquaintance with transistor drivers, and the ability to check and refine a microwave circuit on a computer terminal to be qualified for modern, creative design of microwave semiconductor control components. These subjects are well covered in approximately the first half of the book; the second half treats the general and specific design of switches, at tenuators, limiters, duplexers, and phase shifters, with many ex amples drawn from his experience and that of others. 580 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book is a treatise on the thermodynamic and dynamic properties of thin liquid films at solid surfaces and, in particular, their rupture instabilities. For the quantitative study of these phenomena, polymer thin films (sometimes referred to as 'ultrathin') have proven to be an invaluable experimental model system. What is it that makes thin film instabilities special and interesting First, thin polymeric films have an important range of applications. An understanding of their instabilities is therefore of practical relevance for the design of such films. The first chapter of the book intends to give a snapshot of current applications, and an outlook on promising future ones. Second, thin liquid films are an interdisciplinary research topic, which leads to a fairly heterogeneous community working on the topic. It justifies attempting to write a text which gives a coherent presentation of the field which researchers across their specialized communities might be interested in. Finally, thin liquid films are an interesting laboratory for a theorist to confront a well-established theory, hydrodynamics, with its limits. Thin films are therefore a field in which a highly fruitful exchange and collaboration exists between experimentalists and theorists. The book stretches from the more concrete to more abstract levels of study: we roughly progress from applications via theory and experiment to rigorous mathematical theory. For an experimental scientist, the book should serve as a reference and guide to what is the current consensus of the theoretical underpinnings of the field of thin film dynamics. Controversial problems on which such a consensus has not yet been reached are clearly indicated in the text, as well as discussed in a final chapter. From a theoretical point of view, the field of dewetting has mainly been treated in a mathematically 'light' yet elegant fashion, often making use of scaling arguments. For the untrained researcher, this approach is not always easy to follow. The present book attempts to bridge between the 'light' and the 'rigorous', always with the ambition to enhance insight and understanding - and to not let go the elegance of the theory. 172 pp. Englisch.

So lesen wir auf S. 4: ',Sein' ist nicht so etwas wie Seiendes. ' 'Das Sein des Seienden ,ist' nicht selbst ein Seiendes' (S. 6). Auf S. 27 steht der Satz: 'Die Abhebung des Seins vom Seienden und die Explikation des Seins ist Aufgabe der Ontologie. ' Wenn ein philosophisches Werk ebensowohl nach dem zu beurteilen ist, was in ihm als tragende Voraussetzung unausgesprochen zum Vor schein kommt, als auch nach dem, was es ausdrucklich sagt, dann ist die Sache des Denkens in SuZ. die ontologische Differenz. Die Lage, in der wir uns angesichts der ontologischen Differenz im Denken von und urn SuZ. befinden, ist jedoch in sich proble matisch. 1.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The Finite Element Method, shortly FEM, is a widely used computational tool in structural engineering. For basic design purposes it usually suf ces to apply a linear-elastic analysis. Only for special structures and for forensic investigations the analyst need to apply more advanced features like plasticity and cracking to account for material nonlinearities, or nonlinear relations between strains and displacements for geometrical nonlinearity to account for buckling. Advanced analysis techniques may also be necessary if we have to judge the remaining structural capacity of aging structures. In this book we will abstain from such special cases and focus on everyday jobs. Our goal is the worldwide everyday use of linear-elastic analysis, and dimensioning on basis of these elastic computations. We cover steel and concrete structures, though attention to structural concrete prevails. Structural engineers have access to powerful FEM packages and apply them intensively. Experience makes clear that often they do not understand the software that they are using. This book aims to be a bridge between the software world and structural engineering. Many problems are related to the correct input data and the proper interpretation and handling of output. The book is neither a text on the Finite Element Method, nor a user manual for the software packages. Rather it aims to be a guide to understanding and handling the results gained by such software. We purposely restrict ourselves to structure types which frequently occur in practise. 440 pp. Englisch.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -There is a rapidly expanding literature on the economics of the so called 'new technologies' - especially on those using microelectronic systems. Dr. Jacobsson's book deals with microelectronics-based innovation in machine tools: with the production and use of computer numerically controlled machine tools in the world economy and especially in the Third World. Jacobsson is mainly interested in the implications which CNC machine tools may be expected to have for users and producers in the Newly Industrialising Countries. He approaches this as a problem in applied economics and the book will have a primary interest for those economists whose concern is with the problems of industrialisation in developing countries. It will be parti cularly valuable to those who are preoccupied with the role of local capital goods manufacture and with the technological preconditions for this kind of production. Jacobsson is able to give detailed and specific arguments on these matters as far as CNC machine tools are concerned. In my view, the book has a considerably wider interest and relevance than its specification may at first sight suggest. Jacobsson's achieve ment is not just that he has provided valuable and convincing quantita tive arguments about policy in setting up production of CNC machine tools. In addition, he has set a new and much needed methodological standard for analysis of the impacts of 'new technologies' on the international economy. 276 pp. Englisch.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -How quickly the technological 'flavour of the month' changes. At the beginning of the 1980's many saw 'robotics' as being something of a pana cea for those problems in the manufacturing industries which had been exacerbated by the world recession. Those working at the time in the field of robotics stressed that robots themselves were only part of the solution. Yet in many quarters the 'hype' for the new technology apparently knew few bounds, resulting, inexorably, in many industries painfully discover ing for themselves a new realism, closely followed by disillusionment. In its wider sense the term 'robotics' covers an extremely broad spec trum of technologies ranging from extremely flexible, highly sensory and integrated systems capable of handling a very diverse product range, through to comparatively inflexible, high volume systems which can merely handle slightly different variations of the same basic product. As a result of the one 'buzzword' referring to such a variety of actual system types, the disillusionment which started to become apparent during the early 1980's acted as something of a double edged sword. A given com pany might consider a particular robotics-based technological solution to its production problems, find that it was unsuitable, and so renounce all robotics approaches as inappropriate. Yet just because one position on that spectrum of technological solutions was unsuitable for the company should not have led them to assume that there was no other robotics solu tion that was appropriate. 584 pp. Englisch.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A long and varied experience in many areas of electronic circuit design has convinced me that capacitors are the most misunderstood and misused electronic component. This book provides practical guidance in the understanding, construction, use, and application of capacitors. Theory, combined with circuit application advice, will help to under stand what goes on in each component and in the final design. All chapters are arranged with the theory of the dielectric type discussed first, followed by circuit application information. With all chapters arranged in the same manner, this will make reading and using this book for reference easier. A practical glossary of terms used in the capacitor industry is included. The first chapter covers basic information that applies to all types of capacitors. Each following chapter addresses a different capacitor dielectric. This book could have been titled: 'Everything You Wanted To Know About Capacitors, But Were Afraid To Ask . .' ix Preface THE CAPACITOR HANDBOOK Chapter 1 Fundamentals For All Capacitors For all practical purposes, consider only the parallel plate capacitor as illustrated in Fig. 1.1-two conductors or electrodes separated by a dielectric material of uniform thickness. The conductors can be any material that will conduct electricity easily. The dielectric must be a poor conductor-an insulator.

This item is printed on demand - it takes 3-4 days longer - Neuware -The oceans are vast with t, Yen o-thirds of our planet being covered by a thick layer of water, the depth of which can be likened to flying above the earth's surface at an altitude of 30,000 feet (9,800 m). Good to play in, essential for life but deadly to breathe, water is important to all organisms on the planet, and the oceans form its major reservoir containing approximately 97 per cent of all freely available surface water. In spite of this obvious importance mankind has still much to learn about this ocean environment. Study of the oceans has grown enormously since the eighteenth- and nineteenth-century voyages of scientific discovery, expanding greatly in the period post 1945. One of the subjects that has blossomed in this period has been the study of the ocean's surface, and in particular the study of sea level and related sea-surface changes. Indeed this topic may even be termed 'popular', as reflected in the growing number of general geo morphology, physical geology and oceanography texts which now give space to the subject. 668 pp. Englisch.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Of all industries in the United States, the food industry must in fact be the most regulated by law. If it is not, its competition for this distinction goes unnoticed. All phases of the food industry are subjected to some control by law, beginning with the land food is grown on and the oceans from which it is harvested. Seed and plant stock are sometimes subjected to control such as to the nutritional value of the foods they produce. Acreages of agricultural crops, the quantities of foods to be produced, are regulated. As foods are produced, whether from plants or animals, the substances applied to increase yields or provide protection from pests are controlled to insure safe use. As foods enter and pass through the huge marketing system they are scrutinized from beginning to end by regulatory agents operating under authority of food laws. Those foods which are transformed through various technologies into today's thousands of consumer products are watched carefully to insure the appropriateness and safety of added ingredients, not all of which are natural, and the adequacy of processing, packaging and storage. Finally, the representation of foods to consumers through labeling and advertising is controlled to make sure it is accurate and sufficiently informative. 680 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This text and reference book was written because of the urgings of my colleagues here and abroad and also by my students to fill the need for a comprehensive book describing vegetables important as food crops of the world. in this book was first used as outlines for the course on The material world vegetables taught by the staff of the Department of Vegetable Crops at the University of California at Davis. Over the course of the decade the author taught the course, new topics were added with each succeeding year. In 1978 the handouts were revised and compiled into a syllabus. In addition to the students taking the course, the syllabus was purchased and used by others as a reference book. Word ofits existence travelled far; the syllabus is presently used by one other university in the United States and by another in a foreign country. This edition has been extensively revised; many new materials and references have been added. Included are many photographs taken by the author in his travels abroad. The book has three parts. The first is introductory and background meant for students who are not familiar with vegetables as food crops. 432 pp. Englisch.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The very first winemaster may have been a cave man who discovered the magic of fermentation by tasting the result of some crushed grapes having been left inadvertently for a few days. Wine will, literally, make itself. In simplest terms, yeast cells will collect on the outside of grape skins in the form of bloom and, when exposed to the natural sweetness inside the fruit, fermentation of the sugar into carbon dioxide gas and ethyl alcohol will commence. During the millenia that have transpired since the cave man, the state of the art has evolved into five generally accepted categories of classification. Table wines are usually dry (made with no appreciable amount of fer mentable sugar remaining) or nearly so, and contain less than 14% alcohol by volume. They can be white, pink or red and are the result of uncompli cated processes of fermentation, clarification, stabilization, aging and bot tling. The term table wine suggests the use for which these wines are intended-at the table with food. The overwhelming majority of the wine produced in the world is in this category. Table wines range from the obscure and ordinary to the most expensive classics known to man. 516 pp. Englisch.

There is constant public interest in health and disease; in medical miracles and in breakthroughs; in medical disasters, failures and malpraxis ; in deficiencies and defects ofhealth services; and in the rising costs ofhealth care. Medicine is 'big business'. Physicians co me out near the top money earners in most medical care systems. In the Uni ted Kingdom the National Health Service (NHS) now costs over [6000 million a year ($ ro 800 million), a free service that costs every British man, woman and child [120 a year ($216) in direct and indirect taxes. But this is less than the [500 ($900) a year that medical care costs each person in USA and West Germany. In developed countries health care costs are approaching ro% ofthe gross national product (GNP). It is big business also in that in Britain the NHS is one of the largest employers; about I million Britons work as employees of the NHS, caring for the other 54 millions and in the USA the numbers are 5 million caring for 2. 5 millions. The provision of health services is full of problems and dilemmas. These problems and dilemmas cross all' national boundaries. All countries share the same problems and dilemmas. Problems of objectives, of standards, of effectiveness and efficiency, and problems of relations between the medical profession, the public and govern ment. Medical care still is full of mystique. 164 pp. Englisch.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -One of the eXCltmg challenges of medicine has been the reaching of decisions based on less than complete evidence. As undergraduates in teaching hospitals future physicians are taught to think in clear and absolute black and white terms. Diagnoses in teaching hospitals all are based on supportive positive findings of in vestigations. Treatment follows logically on precise diagnosis. When patients die the causes of death are confirmed at autopsy. How very different is real life in clinical practice, and particularly in family medicine. By the very nature of the common conditions that present diagnoses tend to be imprecise and based on clinical assessment and interpretation. Much of the management and treatment of patients is based on opinions of individual physicians based on their personal expenences. Because of the relative professional isolation offamily physicians within their own practices, not unexpectedly divergent views and opinions are formed. There is nothing wrong in such divergencies because there are no clear absolute black and white decisions. General family practice functions in grey areas of medicine where it is possible and quite correct to hold polarized distinct opinions. The essence of good care must be eternal flexibility and readiness to change long-held cherished opinions. To demonstrate that with many issues in family medicine it is possible to have more than one view I selected 10 clinical and II non -clinical topics and invited colleagues and fellow-practitioners to enter into a debate-in-print. 416 pp. Englisch.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In some countries, especially on the European continent, there still exists a remarkable veal market. This type of meat production seems, irrespective of any economic forecasts, to remain unchallenged so long as consumers expect that restaurants should offer courses like 'r6ti de veaux', 'vitello a la casa' or 'Kalbsschnitzel'. Producers, at least since about the past 1-/2 decades, have been aware of the beneficial effect of anabolic agents in veal production. This is possible due to the lack of endogenous sexual hormones during the juvenile or prepuberal status of these animals. A discussion about the benefit / risk - evaluation in connection with the use of anabolic agents in general was promoted in recent years by the public. This concern occurred concomitantly with the detection of illegally treated veal calves and the occurrence of diethylstilbestrol (DES) residues in canned food containing veal. The aim of this paper is to summarize the present status of residue data in edible tissues and excreta in order to allow the evaluation of the risk (given in the paper of Hoffmann within this program) and to consider reasonable monitoring measures. We have to face the fact that without an efficient control system the illegal treatment of calves can not be excluded. Therefore, this paper will not only consider different compounds and formulations, but will also deal with practised routes of administration. 320 pp. Englisch.

However, this is no longer true at the beginning of the present decade, and the authors are to be congratulated in trying to stimulate their juniors to approach the problems of Pre-natal Paediatrics in a well informed manner. Whilst inactivity may still be the treatment of choice in certain cases, it should only be carried out with the full knowledge that all is well, and this obviously will involve the use and understanding of new investigations and techniques. In my opinion the authors have achieved their aims and though there are those who may always have reservations, they must surely accept the authors' appraisal of the modern approach to this science. VICTOR R. TINDALL Cardiff, I97 I PREFACE This book confines itself to those aspects of pre-natal develop ment which are of importance to the clinician. We hope to present a reasonably concise account of this relatively new and rapidly expanding field of medical science. Stress is given to concepts which may not yet be in many standard obstetric and paediatric texts. Also, we wish to provide an easily accessible collection of reference data for the busy member of junior staff to refer to during the course of his routine work. We therefore make no apology for any repetition needed to make each section readable without many cross references. 240 pp. Englisch.

Vianna Filho In his historical evolution, man has been able to dominate nature by means of his technological achievements, his knowledge and his inventiveness, attaining an increasing control over the world and its organization. As a result, his power over his fellow men has also increased, giving him more ,and more responsibility which leads, of necessity, to one existential problem: is the contemporary man, with all his power and knowledge, really happy Technological progress has brought him several rights and desires: health, better insight into the future and greater control over his own des tiny, but despite all this he still suffers from insecurity and from all the new problems that he has to face, which fact accounts for his imperfections and limitations that inevitably generate anxiety. Anxiety, therefore, constitutes one of the main characteristics of modern man. It can be foreseen today that, in the near future, the entire population of any large city will suffer from anxiety and behave in a 'neurotic' way. Man is seeking relief from pain, suffering and, naturally, also anxiety. Thus all possible efforts are being made to find a solution for this anxiety. The search for substances that are able to eliminate anxiety is one of the constant concerns of modern science, and, in this context, one of the turn ing points, as we will see in this volume, has been the discovery of the chemi cal agents known as the benzodiazepines. 312 pp. Englisch.

TAKADA In the implantation and subsequent development of a fertilized ovum, its integrity is most significant. However, with maternal local factors, i.e., unsatisfactory uterine conditions, implantation may not succeed even if the integrity of the fertilized ovum is excellent; if implantation is made, the maturation of the fetoplacental unit following implantation is disturbed, which leads to abnormalities in fetal development or to miscarriage. Thus, the uteroplacental unit, as well as the fetoplacental unit, plays an important role in the establishment and maintenance of pregnancy. Among the mechanisms of the utero placental unit, most significant is the physiological mechanism of the uterine microvasculature and its correspon dence to gestation. In particular, homeostasis of simultaneous cooperative development of the uterine wall and the placenta is most important. 420 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -In 1977 there were an estimated 1,846,090 patient care episodes in psychiatric hospitals across the United States. The number of patient care episodes in inpatient facilities continues to increase from that measured in 1955 despite the national emphasis on 'deinstitutionalization.' Yet the nature and focus of psychiatric hospitals, both public and private, have changed dramatically in the past fifty years. No longer are all mentally ill patients placed in distant hospitals that encourage separation from family and community. Many hospitals now work to include the patient's natural support system, and families are increasingly vocal about their right to stay involved with their hospitalized family member. As hospital stays have become briefer, the need to incorporate the family in the treatment process has been recognized. We are witnessing the development of new roles for families with the psychiatric hospital and novel treatment strategies offered by inpatient staff to families. These exciting changes have led to an alteration in the attitudes of mental health professionals as well as an expansion of our knowledge and skills regarding the family of the hospitalized psychiatric patient. This book brings together the works of many of those professionals who have developed innovative and pragmatic clinical and research strategies for these families. 352 pp. Englisch.
