Taschenbuch. Condición: Neu. Neuware - Included in this volume is a broad range of topics. Immunology is such a diverse field that many of the subspecialties overlap, and one finds it convenient and necessary to integrate information from several of them. We try to focus on the molecular aspects of immunology as much as is reasonable, but some con tributions consist of ablend of molecular and cellular immunology and even immunopathology. This is as it should be, since information at the molecular level often provides an explanation of phenomena observed at other levels. Myelin basic protein holds the interest of immunologists because it is impli cated in the induction of the autoimmune disease called experimental allergie encephalomyelitis (EAE). Although much biochemical and immunological information about this protein has been uncovered, it is not understood how such an inaccessible self-antigen can serve as the focal point in the central ner vous system for myelin basic protein-specific EAE-inducing T cells. Day dis cusses the problem by first reviewing the sequences of the proteins from several species and the antigenicity of the proteins and peptides derived from them. The reader is then led into a thorough discussion of the immunological relation ships that do and do not influence development of the encephalitis. From this discussion, the author promulgates the bystander model as the best overall mechanism to explain why different fragments of the highly conserved protein are needed by various species to give rise to the same type of localized central nervous system disease.

Taschenbuch. Condición: Neu. Neuware - In their classic paper in 1929, Drury and Szent-Gyorgyi described a number of the important cardiovascular actions of adenosine. Another thirty years were to pass before the possible physiological role of adenosine in coronary vasodilation was studied by Berne and others. Since then, there has been a tremendous increase in research into the actions of adenosine. Workers from many disciplines have employed a wide variety of techniques, since adenosine is a product of and a substrate for a number of metabolic pathways, is transported into cells, and acts at discrete receptor sites to modulate the activity of adenylate cyclase and to produce important actions on many cells and tissues including platelets, adipo cytes, heart, blood vessels, and other smooth muscles. International symposia on the actions of adenosine were held in 1978, 1981, and 1982, and the proceedings of these symposia have been published (Baer and Drummond, 1979; Daly et at., 1983; Berne et at., 1983). Since it is not the primary purpose of the present volume to review our current understanding of the nu merous actions of adenosine, these volumes should be consulted for such details. Rather, the present volume has been planned to provide both graduate students and investigators in pharmacology and related disciplines with a summary of some of the methods now available for the study of the actions of adenosine and, in particular, to highlight their possible uses and limitations.

Taschenbuch. Condición: Neu. Neuware - More than for any other volume of the Handbook of Neurochemistry, the chap ters in this volume on Pathological Neurochemistry deal with the interface of the laboratory bench with the patient's bedside. Most of the chapters reflect the confluence of basic scientists, clinical investigators, and physicians. Con sidered here are many of the more important disorders that afflict the nerves, muscles, spinal cord, and/or brain of mankind throughout the world. There are well over 500 such disorders. And our understanding of their nature and of measures for effective prevention or treatment depends significantly on appli cation of the biochemical disciplines that characterize neurochemistry. Before World War II, any attempt to compile a volume on pathological neurochemistry would have been largely descriptive and very rudimentary, as such 'handbooks' by Hans Winterstein (1929), Irvine Page (1937), and others demonstrate. But thanks to the many major advances in research and tech nology in the postwar decades, we now stand at the threshold of understanding how to manage many of the major neurological disorders, and we may expect more such delineations in the immediate decades ahead. Neurochemistry, de fined broadly, has played a central role in this extraordinary turn of events, progressing from what J. L. W, Thudichum in 1884 called objects of anxious empiricism to his anticipation of the proud exercise of chemical precision.

Taschenbuch. Condición: Neu. Neuware - In 1968 Drs. B. E. C. Nordin and A. Hodgkinson organized the First International Symposium on Urolithiasis Research in Leeds, England. One hundred and five participants from continental Europe, Great Britain, and the United States met to review their work and exchange ideas regarding the formation of urinary calculi. This meeting achieved several important goals. It pulled together a nidus of workers in the many scientific disciplines that relate to urolithiasis. This nidus served as the seed for research growth in a complex, interdisciplinary field. It established a forum for con tinuing communication in urolithiasis research with subsequent sym posia being held every 4 years. The Williamsburg Symposium was the fourth in the Leeds-Madrid Davos series involving 186 participants from throughout the world. A stated emphasis was on clinical research under way in the field. There were no invited speakers and for the first time the 41 papers that were presented orally at the meeting were selected from 184 submitted abstracts. A total of 134 papers were presented in the poster sessions in the afternoons where informal exchange between interested participants and investigators could occur without the restrictions of a plenary session. Virtually all areas of urolithi asis research from the most fundamental physical chemistry to clinical patterns of disease and specific modes of treatment were presented, reviewed and discussed during the meeting.

Taschenbuch. Condición: Neu. Neuware - It is now well known that the concept of drifting continents became an estab lished theory during the 1960s. Not long after this 'revolution in the earth sciences,' researchers began applying the continental drift model to problems in historical biogeography. One such problem was the origin and dispersal of the New World monkeys, the Platyrrhini. Our interests in this subject began in the late 1960s on different conti nents quite independent of one another in the cities of Florence, Italy, and Berkeley, California. In Florence in 1968, A. B. Chiarelli, through stimulating discussions with R. von Koenigswald and B. de Boer, became intrigued with the possibility that a repositioning of the continents of Africa and South America in the early Cenozoic might alter previous traditional conceptions of a North American origin of the Platyrrhini. During the early 1970s this con cept was expanded and pursued by him through discussions with students while serving as visiting professor at the University of Toronto. By this time, publication of the Journal of Human Evolution was well underway, and Dr. Chiarelli as editor encouraged a dialogue emphasizing continental drift models of primate origins which culminated in a series of articles published in that journal during 1974-75. In early 1970, while attending the University of California at Berkeley, R. L. Ciochon was introduced to the concept of continental drift and plate tectonics and their concomitant applications to vertebrate evolution through talks with paleontologist W. A. Clemens and anthropologist S. L. Washburn.

Neuware - The necessity of prediction and fine control in the food manufacturing process is becoming more important than ever before, and food researchers and engineers must confront difficulties arising from the specificity of food materials and the sensitivity of human beings to taste. Fortunately, an overview of world research reveals that the mechanisms of the many complex phenomena found in the food manufacturing process have been gradually elucidated by skilful experiments using new analytical tools, methods and theoretical analyses. This book, the proceedings of the 6th International Congress on Engineering and Food (ICEF6), held for the first time in Asia - in Chiba, Japan May 23 -27, 1993 - summarizes the frontiers of world food engineering in 1993. Congress was joined by the 4th International Conference on Fouling and Cleaning. There were 476 active members from 31 countries participating in the Congress. The editors hope that readers will find this book to be a useful review of the current state of food engineering, and will consider future developments in this research field. The editors extend thanks to the members of the organizing committee of ICEF6, and the advisors, Dr. Ryozo Toei, Professor Emeritus of Kyoto University and Dr. Masao Fujimaki, Professor Emeritus of the University of Tokyo. They also acknowledge the international advisory board members who helped the organizing committee in many ways, and the 10 foundations and 66 companies that financially supported the ICEF6. Finally, the editors are indebted to the reviewers of the manuscripts of these proceedings.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This survey of 13 electrooptic materials includes both a review and compilation of all materials properties relevant to their use in linear (Pockels) electrooptic modulator applications. Information on actual electrooptic modulator design as well as applications for these materials, and data on materials exhibiting a quadratic (Kerr) electrooptic effect, are not included. With these restrictions in mind, every attempt was made to be as comprehensive as possible by utilizing all available sources of literature: books, periodicals, reports, and vendor literature. The files of the Electronic Properties Information Center and full resources of the Hughes Aircraft Company Library were searched for pertinent data, and approximately 1000 articles were reviewed for this pUblication. A brief Introduction to the survey is followed by a description of the Prin ciples of Electrooptic Modulation, emphasizing the importance of crystal symmetry on the electrooptic properties of materials, and including the relationships between the electrooptic, piezooptic, elastooptic and piezoelectric effects in crystals. The survey consists of 13 independent sections, each section covering the properties of one material: crystallographic, optical, electrooptic, photoelastic, piezoelectric, dielectric and thermal. References appearing in the text are listed at the conclusion of each section. Tables and Figures are numbered separately for each section. v TABLE OF CONTENTS INTRODUCTION . - . . . . . 1 PRINCIPLES OF ELECTROOPTIC MODULATION. 5 AMMONIUM DIHYDROGEN ARSENATE (ADA) . 15 AMMONIUM DIHYDROGEN PHOSPHATE (ADP). 268 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The distinction between molecular immunology and immunobiology is neces sarily arbitrary. The most rapid progress is usually made in the blurred area between the two, when the chemist is aware of the full significance of the biological problems, and the biologist is alert to the contribution that a knowl edge of molecular structure can be made to their solution. The range of scientific disciplines able to contribute to research in immunology, which this approach brings, is reflected in the present volume. Protein chemists worked out the arrangement of the polypeptide chains and the amino acid sequences of antibodies and X-ray crystallographers the three dimensional structure, but more precise definition of the amino acid side chain positions in the combining site is required for an understanding of the subtleties of antibody specificity. That this can be achieved with physical techniques such as nuclear magnetic resonance has been shown by R. A. Dwek, and in his chapter he summarizes these results with a minimum of technical detail. The immune response has been shown to be dependent on complex cellular interactions and further progress will be facilitated by investigation of the molecular basis of these interactions. This necessitates study of the structure and organization of the molecules in the surfaces of lymphocytes and other cells. 272 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This has been a year of substantial change for The Year in Endocrinology. The first change, though perhaps only a semantic one, nevertheless represents a landmark. Although last year's volume was designated as the first of an annual series, that seemed to me at the time merely a hope-a realistic hope, perhaps, but a hope, nevertheless. With the publication of this year's volume, however, this can accurately be said to be an annual series, one that we trust will fulfill a need and will therefore continue for years to come. Among other changes from last year's volume are some that were originally intended and others that were unintended. In the former category is the substitution of a chapter on water metabolism and vaso pressin, excellently prepared by Dr. Gary L. Robertson, for the chapter on paraendocrine syndromes that appeared last year. Chapters on these two topics will continue to appear on alternate years. Obviously, the non recurring chapter on a topic of special interest has also changed, and this year's comprises a comprehensive review of autoimmune endocrine dis ease by Drs. Jay Silverberg and Robert Volpe. The unexpected change results from the inability of Dr. Louis Avioli to continue as a member of the Editorial Board. Most fortunately, however, we have persuaded Dr. Charles R. Kleeman to join the Board and to be responsible for the chapter on the parathyroid gland and mineral metabolism. Dr. Kleeman has been assisted on the preparation of this chapter by his daughter, Dr. 420 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The subject of this book is neuroendocrinology, that branch of biological science devoted to the interactions between the two major integrative organ systems of animals-the endocrine and nervous systems. Although this science today reflects a fusion of endocrinology and neurobiology, this synthetic ap proach is relatively recent. At the beginning of the 20th century, when the British physiologists, Bayliss and Starling, first proposed endocrinology to be an independent field of inquiry, they went to great lengths to establish the autonomy of chemical secretions in general and their independence from nervous control in particular (Bayliss, W. M. , and Starling, E. H. , 1902, The mechanism of pancreatic secretion,]. Physiol. 28:325). They argued with Pav lov, who said that there was a strong influence of the nervous system on the gastrointestinal phenomena the endocrinologists were studying. For several decades, the English physiologists prevailed, at least in the West; and Pavlov's critique was not taken to heart by the practitioners of the newly emerging discipline of endocrinology. Through the work of Harris, the Scharrers, Sawyer, Everett, and others, there has been something of a scientific detente in the latter half of this century; the hybrid field of neuroendocrinology is now regarded as one of the corner stones of modern neural science and is of fundamental importance in basic and clinical endocrinology. 588 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The short period since the publication of Volume 1 of Methods in Membrane Biology has been a time of momentous progress. Calorimetry, electron spin and nuclear magnetic resonance, X-ray diffraction, and freeze-cleavage electron microscopy, reinforced by biochemical analyses and enzymatic studies, have led to universal acceptance of a generalized membrane model. All membrane biologists would agree that a major element of all biological membranes is a bilayer of phospholipids which, in some instances, also contains other lipids, notably sterols and glycolipids. The fatty acid com position of the lipids of most membranes is such that the lipids are above their transition temperatures in their normal environment so that the bilayer is fluid. The microviscosity of the fatty acyl groups decreases pro gressively down the chain so that, at the hydrocarbon interior of the bilayer, the lipid phase has a viscosity approximating that of olive oil at room temperature. As a consequence of this membrane fluidity, a phospholipid molecule is very mobile within the plane of the membrane (moving a distance of about 1-2 fLm in 1 s) but the movement of a phospholipid molecule from one side of the membrane bilayer to the other (flip-flop) is very slow. The lipid bilayer is an essentially inert and rather impermeable struc ture, as shown by many studies with model systems. Proteins, of course, provide the catalytic components of the membranes. as well as playing a significant structural role. 324 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Those who are familiar with the two volumes of The Year in Endocrinology may, at first glance, fail to recognize their relationship to the present volume, Contemporary Endocrinology. The name is different and the cover design different, but nonetheless the admonition against judging a book by its cover is very well taken in this instance. In fact, Contemporary Endocrinology is not only the direct linear descendant of The Year in Endocrinology, it is a purposeful clone thereof-the topics are unchanged, the talented group of authors is unchanged, and most importantly, both the objective of the work and the manner in which that objective is approached are unchanged. The objective is, of course, to assist the reader in maintaining currency with respect to important developments, both basic and clinical, in the major areas of endocrinology. We are all much too familiar, unfortunately, with the difficulty of maintaining currency these days. Our approach to dealing with the informational inflation that we are suffering is similar to that used by economists in dealing with monetary inflation, that is, to increase interest. This we have attempted to do by providing for the reader an easy-to-read group of essays in which advances in individual areas of endocrinology are re viewed broadly, synthesized, and placed into perspective by a group of authors who are authorities in their individual fields. They serve, not as guest artists, but as members of a stable Editorial Board that provides continuity by contributing to successive volumes. 420 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Rapid advances in knowledge have led to an increasing interest in neuro biology over the last several years. These advances have been made possible, at least in part, by the use of increasingly sophisticated methodology. Furthermore, research in the most rapidly advancing areas is essentially multidisciplinary and is characterized by contributions from many investi gators employing a variety of techniques. While a grasp of fundamental neurobiological concepts is an obvious prerequisite for those who wish to follow or participate in this field, critical awareness and evaluation of neurobiological research also requires an understanding of sophisticated methodologies. The objective of Methods in Neurobiology is the development of such critical abilities. The reader is exposed to the basic concepts, principles, and instrumentation of key methodologies, and the application of each meth odology is placed in the special context of neurobiological research. The reader will gain familiarity with the terminology and procedures of each method and the ability to evaluate results in light of the particular features of neurobiological preparations and applications. 616 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume, the second in the Methods in Pharmacology series, contains some of the physical methods which either have been or could be applied to pharmaco logical problems. A major emphasis has been placed on spectroscopic techniques, particularly those, such as optical rotatory dispersion and circular dichroism, fluorescence spectroscopy, magnetic resonance spectroscopy, ultraviolet absorption spectroscopy, stopped flow and relaxation spectrometry, Mossbauer spectroscopy, light scatter and x-ray crystallography, that can be used to study drug interactions with biological systems at a molecular level. Although phosphorescence spectro scopy and oscillographic polarography can also be used to study drug interactions, their main usefulness is in the detection and estimation of drugs and their meta bolities in body tissues and fluids. Mass spectrometry is a powerful tool for study ing the metabolism of drugs as well as for detecting abnormal endogenous metabolites in the body. Finally, heatburst microcalorimetry is a non spectroscopic technique that can be used to study how drugs and other ligands interact with biological macromolecules. Each chapter contains a brief introduction to the theoretical basis for each technique as well as a description of the instrumentation involved. This is followed by a section describing the application of the technique to pharmacological prob lems. Where these are not available, examples have been drawn from the other life sciences. In a final section, some further applications of each technique to problems in pharmacology are suggested. 512 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This is the first book that is devoted entirely to a discussion of the effects on drinking behavior of sensory stimulation of the tongue and mouth. As Blass and Hall (J 976) have recently pointed out, there has been an overrejection of the emphasis by Cannon (1932) and Hull (1943) on the peripheral origins (e. g. , dry mouth, empty stomach) of the control of ingestive behavior. Thus most present-day investigators of drinking behavior have been concentrat ing on central mechanisms of control, to the neglect of the periphery. In this volume we have attempted to bring together much of the pertinent 'peripheral' literature through originally written chapters that are concerned with the role of orosensory factors in the mediation of drinking and licking. Postingestive effects of fluids receive little attention. Indeed, two chapters deal with consummatory licking in the absence of intake of fluids. A good understanding of the consequences of orosensory stimulation on licking and drinking behavior requires insight into the functional anatomy of the tongue and mouth, the characteristics of the licking response and the problem of recording of licking behavior. Several chapters deal with these subjects. It has not only been a pleasure but also a privilege to edit this volume. We have learned much from the expert treatment of the different aspects of licking and drinking behavior by the chapters' authors. 440 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The early era of neural network hardware design (starting at 1985) was mainly technology driven. Designers used almost exclusively analog signal processing concepts for the recall mode. Learning was deemed not to cause a problem because the number of implementable synapses was still so low that the determination of weights and thresholds could be left to conventional computers. Instead, designers tried to directly map neural parallelity into hardware. The architectural concepts were accordingly simple and produced the so called interconnection problem which, in turn, made many engineers believe it could be solved by optical implementation in adequate fashion only. Furthermore, the inherent fault-tolerance and limited computation accuracy of neural networks were claimed to justify that little effort is to be spend on careful design, but most effort be put on technology issues. As a result, it was almost impossible to predict whether an electronic neural network would function in the way it was simulated to do. This limited the use of the first neuro-chips for further experimentation, not to mention that real-world applications called for much more synapses than could be implemented on a single chip at that time. Meanwhile matters have matured. It is recognized that isolated definition of the effort of analog multiplication, for instance, would be just as inappropriate on the part ofthe chip designer as determination of the weights by simulation, without allowing for the computing accuracy that can be achieved, on the part of the user. 360 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Neurochemistry, having the objective of elucidating biochemical processes subserving nervous activity, emerged as an application of chemistry to the of neurobiological problems as a post-World War II phenomenon. investigation However, only in the last 40 years has the chemical community recognized neurochemistry as a distinct, if hybrid, discipline. During this period great strides have been made. However, recently neurochemistry, along with neu rophysiology, neuropharmacology, neuroanatomy, and the behavioral sci ences, has emerged to form neuroscience, a new community of scientists with its own national society, journals, and meetings. Actually, this recently formed hybrid, neuroscience, is in the process of merging with another well-established discipline, molecular genetics (frequently called molecular biology, and itself a hybrid), which appears to have sufficient hybrid vigor to form yet a new community of scientists, which, for want of a more imaginative term, has been called molecular genetic neuroscience. Clearly, advantages resulting from such mergers or hybridizations accrue not only from the merging discipline (neurochemistry in this case) to the new community (molecular genetic neuroscience), but also in the reverse direction. This Foreword will be concerned primarily with examples of this latter process. 736 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Two central ideas in the movement toward advanced automation systems are the office-of-the-future (or office automation system), and the factory of-the-future (or factory automation system). An office automation system is an integrated system with diversified office equipment, communication devices, intelligent terminals, intelligent copiers, etc., for providing information management and control in a dis tributed office environment. A factory automation system is also an inte grated system with programmable machine tools, robots, and other pro cess equipment such as new 'peripherals,' for providing manufacturing information management and control. Such advanced automation systems can be regarded as the response to the demand for greater variety, greater flexibility, customized designs, rapid response, and 'Just-in-time' delivery of office services or manufac tured goods. The economy of scope, which allows the production of a vari ety of similar products in random order, gradually replaces the economy of scale derived from overall volume of operations. In other words, we are gradually switching from the production of large volumes of standard products to systems for the production of a wide variety of similar products in small batches. This is the phenomenon of 'demassification' of the marketplace, as described by Alvin Toffier in The Third Wave. 544 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -THE PHYSICAL BASIS FOR HETEROGENEOUS CATALYSIS is the proceedings of the ninth Battelle Colloquium in the Materials Sciences, held in Gstaad, Switzerland, September 2-6, 1974. It took as its theme the application of modern theoretical and experimental surface physics to heterogeneous catalysis. Progress in the field by classical chemical methods seemed to have slowed down, at a time when the need for better catalysts was particularly great. The Organizing Committee thought it might be possible to accelerate progress by the application of the powerful techniques evolved in recent years for studying atomically clean surfaces. However, the translation of ideas derived from clean single crystal surfaces with well characterized chemisorbed layers to real catalysts with high ratios of surface to mass on which reactions were taking place and requiring transport of mass and energy is a giant step, raising many questions and requiring thorough discussion by surface physicists on the one hand and catalytic chemists on the other. The 1974 Battelle Colloquium provided a forum for this exchange. As its usual custom, the Colloquium started the first day of introduc tory lectures by three distinguished scientists who have contributed impor tantly over many years to this field. 628 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The Electronic Properties Information Center has developed the Data Table as a precis of the most reliable information available for the physical, crystallographic, mechanical, thermal, electronic, magnetic and optical properties of a given material. Data Tables serve as an introduction to the graphic data compilations on the material published by the Electronic Properties Information Center, EPIC, as Data Sheets. Although the Data Sheets are principally concerned, according to the scope of the Center, with electronic and optical data, it is believed that data covering the complete property spectrum is of the first importance to every scientist and engineer, whatever his information requirements. The enthusiastic reception of these Data Tables has confirmed this opinion and increasing requests for this highly selective type of information has resulted in these III -V Semiconductor Compounds Data Tables. The major problem in this type of selective data compilation on a semiconducting material, lies in the material purity. Properties may vary so widely with doping, crystallinity, defects, geometric forms and the other parameters of preparation, that any attempts at comparison normally fail. On this basis, we have consis tently attempted to give values derived from experiments on the highest purity single crystals or epitaxial films. At the very least, these data should be reproducible and this gives the data their principal validity. If such values however, are not available, then the next best data are reported, together with material speci fications. These latter include the carrier concentration and the dopant. 124 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book deals with a subject that has been studied since the beginning of physical chemistry. Despite the thousands of articles and scores of books devoted to solvation thermodynamics, I feel that some fundamen tal and well-established concepts underlying the traditional approach to this subject are not satisfactory and need revision. The main reason for this need is that solvation thermodynamics has traditionally been treated in the context of classical (macroscopic) ther modynamics alone. However, solvation is inherently a molecular pro cess, dependent upon local rather than macroscopic properties of the system. Therefore, the starting point should be based on statistical mechanical methods. For many years it has been believed that certain thermodynamic quantities, such as the standard free energy (or enthalpy or entropy) of solution, may be used as measures of the corresponding functions of solvation of a given solute in a given solvent. I first challenged this notion in a paper published in 1978 based on analysis at the molecular level. During the past ten years, I have introduced several new quantities which, in my opinion, should replace the conventional measures of solvation thermodynamics. To avoid confusing the new quantities with those referred to conventionally in the literature as standard quantities of solvation, I called these 'nonconventional,' 'generalized,' and 'local' standard quantities and attempted to point out the advantages of these new quantities over the conventional ones. 264 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The purpose of this book is to present computationally efficient algorithms for calculating the dynamics of robot mechanisms represented as systems of rigid bodies. The efficiency is achieved by the use of recursive formulations of the equations of motion, i.e. formulations in which the equations of motion are expressed implicitly in terms of recurrence relations between the quantities describing the system. The use of recursive formulations in dynamics is fairly new, 50 the principles of their operation and reasons for their efficiency are explained. Three main algorithms are described: the recursIve Newton-Euler formulation for inverse dynamics (the calculation of the forces given the accelerations), and the composite-rigid-body and articulated-body methods for forward dynamics (the calculation of the accelerations given the forces). These algorithms are initially described in terms of an un-branched, open loop kinematic chain -- a typical serial robot mechanism. This is done to keep the descriptions of the algorithms simple, and is in line with descriptions appearing in the literature. Once the basic algorithms have been introduced, the restrictions on the mechanism are lifted and the algorithms are extended to cope with kinematic trees and loops, and general constraints at the joints. The problem of simulating the effect of contact between a robot and its environment is also considered. Some consideration is given to the details and practical problems of implementing these algori hms on a computer. 224 pp. Englisch.

In equation (1) it is useful to regard the product AB as the product of two operators in cases in which A and B refer to different spatial points in a condensed matter sys tem and/or in which A and B behave dynamically in a quasiharmonic way. In the second case, one has a two quasiparticle correlation function and CAB;AB(w) gives information about quasiparticle inter actions. Condensed matter physics has increasingly turned its attention to correlation functions of this type during the last 15 years, partly because the two point and/or one-particle correlation functions have by now been very thoroughly studied in many cases. The study of four point and/or two quasiparticle correlations has proceeded somewhat independently in several diverse fields of condensed matter physics and it was one purpose of the institute to bring experts from these different fields together to describe the current state of their art to each other and to advanced students. 680 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -It is now more than twenty years since a proposal was first mooted to hold an international tunnelling symposium in Britain. At the time of the first symposium, held in London in 1976, the Channel Tunnel pro ject had just been shelved. Last weekend a charity walk was held in the finished tunnel, which will be open for business later in the year. Tunnels have figured prominently, and at times spectacularly, in the development of national and international links and it is hoped that such links gather pace in the future. It is particularly pleasing that Alastair Biggart of Storebrelt has agreed to deliver the twenty-sixth Sir Julius Wernher Memorial Lecture of the Institution of Mining and Metallurgy, entitled 'The changing face of tunnelling', at the start of this event. \* Although almost every edition of the technical journals on tunnelling reports another £1 billion scheme somewhere in the world, it would be unfair of me to suggest that tunnelling is restricted to these prestigious schemes for major transport links. Much of the work that makes mod ern life possible receives hardly a mention outside the technical press and one suspects that society at large applies the 'out of sight, out of mind' attitude even more readily to underground construction than it does to other forms of engineering. Clearly, there is a contiiming need to improve the capacity and performance of our infrastructure, while hav ing a careful regard for the environment. 848 pp. Englisch.

Differential growth creates form: external form through growth rates which vary from one part of the body to another and one tissue to another; and internal form through the series of time-entrained events which build up in each cell the special ized complexity of its particular function. We make no distinction, then, between growth and development, and if we have not included accounts of differentiation it is simply because we had to draw a quite arbitrary line somewhere. It is only rather recently that those involved in pediatrics and child health have come to realize that growth is the basic science peculiar to their art. It is a science which uses and incorporates the traditional disciplines of anatomy, physiology, biophysics, biochemistry, and biology. It is indeed apart ofbiology, and the study of human growth is a part of the curriculum of the rejuvenated science of Human Biology. What growth is not is aseries of charts of height and weight. Growth standards are useful and necessary, and their construction is by no means void of intellectualchallenge. Theyare a basic instrument in pediatric epidemiology. But they do not appear in this book, any more than clinical accounts of growth disorders. This appears to be the first large handbook-in three volumes-devoted to Human Growth. Smaller textbooks on the subject began to appear in the late nineteenth century, some written by pediatricians and some by anthropologists. 656 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -to the English edition Many processes that describe the operation of engineering, economic, organiza tional, and other systems are represented as sequences of operations performed on material, information, or other types of flows. Typical examples are processes of connection of telephone users, data transmission and processing, calculation at multi user computer centers, and queueing at service centers. The models studied by the theory of service systems, or queueing theory, are used to describe such processes. The more pessimistic term 'queueing theory' is used more often in the non-Soviet literature. Random arrivals (requests for service), probability distributions defining queueing processes (distributions of service times and acceptable waiting times), and structure parameters (customer priorities, parameters that delimit acceptable queues, parameters that define paths of customers, etc.) are characteristic com ponents of queueing models. Typical output characteristics of queueing models are the probability distributions of queue lengths, waiting times, lengths of busy periods, and so forth. 448 pp. Englisch.

The requirement for a second edition is also a measure of the need for such a book. My experience as a lecturer has shown that what is needed first is an intelligible framework which can be read in a reasonable period of time. Armed with these principles, a student can then go to reviews and the original literature with a reasonable chance of understanding the jargon and the details. Molecular genetics is now so well advanced that it is easy to lose track of the purpose of a set of experiments in the wealth of sequence data and complex interactions. I have therefore kept the same format for this edition with a well-illustrated text giving original papers, popular reviews, monographs and detailed reviews to enable the student to take the subject further as required. 228 pp. Englisch.

Nevertheless, our discipline has such difficulties in coming to grips with its substance that I have found myself getting involved in fww to do it persistently and since the beginning of my career. That career has been divided between diagnosis and research, the balance between them swinging gradually from the former to the latter. To the astonishment of many of my students and colleagues, I have never become a psychotherapist nor a psychoanalyst, though I have looked closely over the shoulders of many friends at their work, have attended continuous case seminars, and have participated in research on psychotherapy and psychoanalysis enough to feel that I have a pretty good grasp of what that kind of endeavor is like. So I have been writing about method, diagnostic and investigative, for over 25 years, and was happy to accept the suggestion of Seymour Weingar ten, of Plenum Press, that I publish a collection of these papers. What has ended up as two volumes was originally conceived as one, for I feel that there is more similarity of method in assessment, prediction, and research than appears on the surface. The General Introduction and Chapter 1 of Volume 1 state the point of view of the entire work. 364 pp. Englisch.
