Buch. Condizione: Neu. Neuware - The VHSIC Hardware Description Language (VHDL) provides a standard machine processable notation for describing hardware. VHDL is the result of a collaborative effort between IBM, Intermetrics, and Texas Instruments; sponsored by the Very High Speed Integrated Cir cuits (VHSIC) program office of the Department of Defense, beginning in 1981. Today it is an IEEE standard (1076-1987), and several simulators and other automated support tools for it are available commercially. By providing a standard notation for describing hardware, especially in the early stages of the hardware design process, VHDL is expected to reduce both the time lag and the cost involved in building new systems and upgrading existing ones. VHDL is the result of an evolutionary approach to language devel opment starting with high level hardware description languages existing in 1981. It has a decidedly programming language flavor, resulting both from the orientation of hardware languages of that time, and from a ma jor requirement that VHDL use Ada constructs wherever appropriate. During the 1980's there has been an increasing current of research into high level specification languages for systems, particularly in the software area, and new methods of utilizing specifications in systems de velopment. This activity is worldwide and includes, for example, object oriented design, various rigorous development methods, mathematical verification, and synthesis from high level specifications. VAL (VHDL Annotation Language) is a simple further step in the evolution of hardware description languages in the direction of applying new methods that have developed since VHDL was designed.…

Buch. Condizione: Neu. Neuware - This treatise had its origins in the authors' strong opinion that the discovery of new drugs, especially of innovative therapeutic agents, really does not happen as a spontaneous sequel to investiga tive research, no matter how penetrating such research may be. Rather, it seemed to us that the discovery of innovative therapeutic agents was a very active process, existing in and of itself, and demanding full attention-it was not simply a passive, dependent by-process of investigative research. And yet, many researchers some close confreres of the authors, others more distant-believed otherwise. We felt that their view reflected unrealistic thinking and that reality probably lay closer to what Beyer' maintained: We are taught to believe that if we can understand a disease it should be easy enough to figure out, say, the molecular configuration of a definitive receptor mechanism somewhere along the line and to design a specific drug . . . . And so we start out to understand the disease but never get around to doing much about therapy. The authors very soon realized that there was essentially no quantitive information available on just where and how innovative therapeutic agents were discovered. There were only anecdotal accounts, and these were able to be selected and presented in ways that could be used to defend any point of view. …

Buch. Condizione: Neu. Neuware - The purpose of these volumes is to provide a reference work for the methods of purifying many of the receptors we know about. This be comes increasingly important as full-length receptors are overexpressed in bacteria or in insect cell systems. A major problem for abundantly expressed proteins will be their purification. In addition to purification protocols, many other details can be found concerning an individual receptor that may not be available in standard texts or monographs. No book of this type is available as a compendium of purification procedures. Receptor Purification provides protocols for the purification of a wide variety of receptors. These include receptors that bind: neurotransmit ters, polypeptide hormones, steroid hormones, and ligands for related members of the steroid supergene family and others, including receptors involved in bacterial motion. The text of this information is substantial, so as to require its publication in two volumes. Consequently, a division was made by grouping receptors by the nature of their ligands. Thus, in Volume One there are contributions on serotonin receptors, adrenergic receptors, the purification of GTP-binding proteins, opioid receptors, neurotensin receptor, luteinizing hormone receptor, human chorionic gonadotropin receptor, follicle stimulating hormone receptor, thyro tropin receptor, prolactin receptor, epidermal growth factor receptor, platelet derived growth factor receptor, colony stimulating factor recep tor, insulin-like growth factor receptors, insulin receptor, fibronectin receptor, interferon receptor, and the cholecystokinin receptor.…

Buch. Condizione: Neu. Neuware - construction. Naturally, we are open to suggestions from all readers of, and contributors to, the series regarding its approach and content. Finally, I would like to thank all those who have helped the launch of this series. The encouraging response received from authors who have contributed the forthcoming volumes and from the subscribers to the series has indicated the need for such a publication. Homa Motamen-Scobi London December 1987 Preface In 1990 both OPEC and the OECD will celebrate their thirtieth anntvers aries. OPEC was founded - rather unnoticed - by oil-producing countries still struggling to gain control over national petroleum resources. Future members were still under colonial rule. The foremost aim of the new organization - years before it was able to make metropolitan newspaper headlines - was stabilizing oil prices. Stability in those days meant prevent ing oil prices from falling in real terms. The OECD was formed by mostly mature industrial economies marking the normalization of the postwar international economy after years of reconstruction, strict trade regulations, etc. The aim of the new organization was to promote 'the highest sustainable growth and employment' in member countries. Incidentally, 1960 was also the year which gave birth to a more loosely defined block in the world community, namely the underdeveloped countries, qS the African colonial empires finally broke up. The two organizations became adversaries in the 1970s in the power struggle over the energy flows of the world.…

Buch. Condizione: Neu. Neuware - This work is concerned with Cystic Fibrosis (CF), the most common fatal genetic disease in the Caucasian population. The decade of the 1980s was one of spectacular progress in understanding the genetic and molecu lar basis of CF. The research breakthroughs of the decade began with the first fundamental insights, published in 1981-1983, into the basic cellular pathophysiology of CF with demonstrations of altered ion transport in spe cialized exocrine epithelial tissues (1-3). Research progress shifted into a triumph of 'reverse genetics,' using restriction-fragment-Iength polymor phism DNA technology (4), with the localization of the CF gene to a region of chromosome 7 (5-7). Understanding, accelerated by an explOSion of in vitro methodologies for epithelial cell culture and transformation, allowed and physiological studies (8-11); these focused, controlled biochemical with increasing precision, on the molecular pathology of distal steps in the regulatory pathways for epithelial ion transport (12-19). Finally, the 'end of the beginning' occurred in late 1989 with one of the great achievements of molecular genetics, the isolation and cloning of the CF gene (20). As a result, we now have a CF gene product, the cystic fibrosis transmembrane regulator (CFfR), possessing predicted amino acid sequence, suggested tertiary structure, and possible transmembrane transport function (21). These amazing developments have set the stage for the next round of advances, which surely will include: 1.…

Buch. Condizione: Neu. Neuware - This volume, SCIENCE OF SINTERING: NEW DIRECTIONS FOR MATERIALS PROCESSING AND MICROSTRUCTURAL CONTROL, contains the edited Proceedings of the Seventh World Round Table Conference on Sintering, held in Herceg-Novi, Yugoslavia, Aug. 28 - Sept. 1, 1989. It was organized by the International Institute for the Science of Sintering (IISS), headquartered in Belgrade, Yugoslavia. Every fourth year since 1969, the Institute has organized such a Round Table Conference on Sintering; each has taken place at some selected location within Yugoslavia. A separate series of IISS Topical Sintering Symposia (Summer Schools) have also been held at four year intervals, but they have been offset by about two years, so they occur between the main Conferences. As a rule, the Topical Sintering Symposia have been devoted to more specific topics and they also take place in different countries. The aim of these Conferences and their related 'Summer Schools' has been to bring together scientists from all over the world who work in various fields of science and technology concerned with sintering and sintered materials. A total of seven IISS Conferences have been held over the period 1969-1989, and they have been supplemented by the four Topical Sintering Symposia held in Yugoslavia, Poland, India and Japan (in 1975, 1979, 1983 and 1987, respectively). This most recent five day Conference addressed the fundamental scientific background as well as the technological state-of-the-art pertinent to science of sintering and high technology sintered materials.…

Buch. Condizione: Neu. Neuware - Gallium Arsenide technology has come of age. GaAs integrated circuits are available today as gate arrays with an operating speed in excess of one Gigabits per second. Special purpose GaAs circuits are used in optical fiber digital communications systems for the purpose of regeneration, multiplexing and switching of the optical signals. As advances in fabrication and packaging techniques are made, the operat ing speed will further increase and the cost of production will reach a point where large scale application of GaAs circuits will be economical in these and other systems where speed is paramount. This book is written for students and engineers who wish to enter into this new field of electronics for the first time and who wish to embark on a serious study of the subject of GaAs circuit design. No prior knowledge of GaAs technology is assumed though some previous experience with MOS circuit design will be helpful. A good part of the book is devoted to circuit analysis, to the extent that is possible for non linear circuits. The circuit model of the GaAs transistor is derived from first principles and analytic formulas useful in predicting the approxi mate circuit performance are also derived. Computer simulation is used throughout the book to show the expected performance and to study the effects of parameter variations.…

Buch. Condizione: Neu. Neuware - Over the past decade, techniques have been developed and implemented to observe metabolism noninvasively in localized regions of intact, living experimental animals and humans through the use of magnetic resonance spectroscopy (MRS). At the same time, magnetic resonance imaging (MRI) techniques developed in the 1970s and refined in this decade have been increasingly applied as a powerful clinical tool to probe human anatomy. Because of the unusual metabolic and physiologic characteristics of malignant tissues, oncology has been one of the primary focuses of the application of both MRS and MRI. Although considerable progress has been made in oncologic applications of magnetic resonance (MR), further research is needed to realize the full potential of MR in this area. Consequently, the 21st Annual Detroit Cancer Symposium entitled 'Magnetic Resonance in Experimental and Clin ical Oncology' was organized to provide a forum for researchers in the field to report the state of the art of MRS and MRI in oncol ogy, to discuss future goals for MRS and MRI in oncology, and to define the research needed to meet those goals. The major emphasis of the symposium was on MRS due to both the recent widespread availability of clinical MRS instrumentation and the extensive amount of animal MRS research performed over the past half decade.…

Buch. Condizione: Neu. Neuware - The papersin this volume are as a resultofcontributions given at the NATO Advanced Study Institute heldat L1andinam Building, University CollegeofWales, Aberystwyth, 10 - 23 September 1989. The Institute considered the physical and chemical propertiesof a variety ofcolloidal systems ranging from simple micellar solutions to concentrated colloidal dispersions. The purpose ofthe NATO Advanced Study Institute was to create a forum so that research scientists working in different areas concerned with colloid science could interact. The emphasL oft1'l. ;: contributions were on the interpretation ofthe different experimental and theoretical approach to give information on the structure, dynamics and equilibrium propertiesofthese systems. The application ofseveral different techniques in colloid science have been described; new developments and perspectives have been covered by several authors. The present volume reviews the current stale ofthe art in this area and it is hoped that it will be used as an incentive for further studies particularlywith reference to new areas ofresearch. In the organisation ofthe scientific programme for the NATO meeting we would like to acknowledge the assistance ofProfessors J. Lyklema, D. G. Hall and J. Holzwarth.

Lewy and E. Heinz which has never been presented in book form. An exposition of the Heinz-Lewy theory requires auxiliary material which can be found in various monographs, but which is presented here, in part because the focus is different, and also because these notes have an introductory character. Self-contained introductions to the regularity theory of elliptic systems, the theory of pseudoanalytic functions and the theory of conformal mappings are included. These notes grew out of a seminar given at the University of Kentucky in the fall of 1988 and are intended for graduate students and researchers interested in this area. 148 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The theory of surgery on manifolds has been generalized to categories of manifolds with group actions in several different ways. This book discusses some basic properties that such theories have in common. Special emphasis is placed on analogs of the fourfold periodicity theorems in ordinary surgery and the roles of standard general position hypotheses on the strata of manifolds with group actions. The contents of the book presuppose some familiarity with the basic ideas of surgery theory and transformation groups, but no previous knowledge of equivariant surgery is assumed. The book is designed to serve either as an introduction to equivariant surgery theory for advanced graduate students and researchers in related areas, or as an account of the authors' previously unpublished work on periodicity for specialists in surgery theory or transformation groups. 236 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Because integrated optics and optoelectronics technology have been devel oping very rapidly during the past few years, significant advances have been made since the first edition of this book was published. Furthermore, interest in the book itself has been strong, leading to a demand for a new, updated version of the text. This has motivated us to issue the present revised pa perback edition, whose lower price will make it more easily accessible to researchers in the area and to interested graduate students, in particular. The present edition is essentially similar to the original hardcover book, except that a new chapter (Chap. 7) has been added, which briefly reviews the recent advances in the area and provides new references. Typographical errors spotted in the original edition have also been corrected. Although great care has been exercised, some errors may still occur in the text and other improvements could be introduced in a possible future edition. The volume editor would therefore appreciate any comments from readers, who are urged to communicate their suggestions directly to him. 436 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This monograph is concerned with the design of feedback controllers for linear multivariable systems, which are robust to system uncertainty. System uncertainty can be realistically represented by including perturbations with bounded H -norm, and this is the approach taken here. For a given H -norm bound, there is a family of robustly stabilizing controllers, and the central question in this book is which of these controllers to choose. One choice to take is that which minimizes the enthropy of the resulting closed loop transfer function, and the derivation and properties of this solution occupies most of this monograph. Explicit formulae are obtained for the minimum enthropy solution, which is a precisely defined compromise between the Linear Quadratic Gaussian optimal solution and the H -optimal solution. The book will be appropriate for graduate classes requiring only a first course in state-space methods, and some elementary knowledge of H control and Linear Quadratic Gaussian control. 160 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Exceptional Children: Integrating Research and Teaching provides a com prehensive introduction to the constantly changing area of special educa tion. The book is research-based, and its title reflects our opinion regarding the important link between research and classroom practice. There is one feature of Exceptional Children: Integrating Research and Teaching that warrants attention and perhaps justification; it was written specifically to address the graduate student or sophisticated undergraduate student mar ket. As such, the book is written at a higher level and with a greater concept density than typical introductory special education texts. We feel that this type of book is very much needed and will be received favorably by the special education community. There are also several unique features of Exceptional Children: Integrat ing Research and Teaching that we feel will be quite valuable. First, we have emphasized the area of teaching practices and not simply included basic facts about definitions, characteristics, and causes. Although some intro ductory texts include information about teaching considerations, that area is not discussed as in depth as it is in our text. We feel that it is important that readers not only understand the educational needs of exceptional chil dren, but also can identify the best educational practices to meet those needs. 419 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The 'Europe against Cancer' programme has, from its inception, emphasised the key role which general practitioners must play in the actions necessary to achieve its aim of reduc ing the incidence and the mortality from cancer in the European Community. General practitioners, because of their day-to-day direct and continuing contact with patients, playa role not only in primary prevention and education of patients, but also in motivating their patients to accept secondary prevention and screening, some of it carried out by general practitioners themselves. These preventive activities are in addition to their traditional role in the care and management of patients with cancer at home, and increas ingly, their role in active treatment. In view of the importance of the general practitioner in the 'Europe against Cancer' pro gramme, the European Commission, with a view to providing general practitioners with up-tO-date useful information, has sponsored the production of this series of publications on organ based cancers, especially written for general practitioners. MICHEL RICHONNIER Coordinator of the' Europe against Cancer' programme, Commission ofthe European Communities, Brussels Preface The present textbook is the second in the series published by the Commission of the Euro pean Communities within the context of the 'Europe Against Cancer' Programme. After lung cancer, it was felt that priority should be given to breast cancer, the most frequent neoplastic disease among European women. 84 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book provides an up-to-date knowledge on theory and experimental results of rate-dependent fracture processes in metallic materials. The objective is to expose the current status of a growing branch of fracture mechanics called generally 'Dynamic Fracture'. Crack dynamics takes into account not only the effects of inertia but also rate sensitivity of a material under consideration. This volume has been prepared by four leading authorities in fracture dynamics: D.R. Curran, J.F. Kalthoff, J.R. Klepaczko and F. Nilsson. A broad range of problem is covered: dynamic fracture theory, application of dynamic fracture mechanics, dynamic crack inition and microstatistical fracture mechanics in dynamic fracture. The book in its present format may serve as a text supplement in lecturing on fracture mechanics. On the other hand, it may serve as an instructional aid in engineering of fracture prevention. 504 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book presents a comprehensive catalogue of elementary data types like sets, maps, orders, trees and lists, written in Ada. Such data types are often used in systems programming. The major focus is on: - a uniform syntactic and semantic interface for all data types, - many implementation variants per data type, all ac cessible through a single interface, - a hierarchical system of the data types as a basis for data type selection and implementation. Meeting these goals is the main achievement of the book. The combination of efficient applicability and ease of learning and maintenance is achieved by the carefully elaborated interfaces of the catalogue's data types. These interfaces combine abstraction, which is necessary for easy learning and for leaving implementation freedom, and functional completeness, which is an essential prerequisite for high performance in different application contexts. The selection of the right data type implementation for a given context is supported by the data type hierarchy which imposes different abstraction levels, and an orthogonal scheme of implementation variants which can be freely combined. Together with the uniformity of interfaces, the hierarchical composition of the catalogue leads to a small code base, from which different implementation variants are generated using a macro processor. 360 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -There has been a great advance in the understanding of processes of meta morphism and of metamorphic rocks since the last edition of this book appeared. Methods for determining temperatures and pressures have become almost routine, and there is a wide appreciation that there is not a single temperature and pressure of metamorphism, but that rocks may preserve, in their minerals, chemistry and textures, traces of their history of burial, heating, deformation and permeation by fluids. However, this excit ing new knowledge is still often difficult for non-specialists to understand, and this book, like the first edition, aims at enlightenment. I have concen trated on the interpretation of the plate tectonic settings of metamorphism, rather than following a geochemical approach. Although there is an impress ive degree of agreement between the two, I believe that attempting to discover the tectonic conditions accompanying rock recrystallization will more readily arouse the interest of the beginner. I have used a series of case histories, as in the first edition, drawing on my own direct experience as far as possible. This m~ns that some subjects are treated in more detail than others, and many important topics are barely mentioned at all. It also means that general concepts appear in a rather haphazard order in the text. To help my readers, I have provided a glossary of definitions of terms used in the book, which are indicated in bold type in the text. 244 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The classicallossless inverse scattering (LIS) problem of network theory is to find all possible representations of a given Schur function s(z) (i. e. , a function which is analytic and contractive in the open unit disc D) in terms of an appropriately restricted class of linear fractional transformations. These linear fractional transformations corre spond to lossless, causal, time-invariant two port networks and from this point of view, s(z) may be interpreted as the input transfer function of such a network with a suitable load. More precisely, the sought for representation is of the form s(Z) = -{ -A(Z)SL(Z) + B(z)}{ -C(Z)SL(Z) + D(z)} -1 , (1. 1) where 'the load' SL(Z) is again a Schur function and _ [A(Z) B(Z)] 0( ) (1. 2) Z - C(z) D(z) is a 2 x 2 J inner function with respect to the signature matrix This means that 0 is meromorphic in D and 0(z) J0(z) ::5 J (1. 3) for every point zED at which 0 is analytic with equality at almost every point on the boundary Izi = 1.
