Taschenbuch. Condizione: 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 reas…onable, 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. Condizione: 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. Condizione: 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. Condizione: 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 origi…n 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.

Taschenbuch. Condizione: 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 f…ormation 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. Condizione: Neu. 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. Condizione: Neu. Neuware - TRACK 1: Innovative Applications in the Public Sector The integration of multimedia based applications and the information superhighway fundamentally concerns the creation of a communication technology to support the ac tivities of people. Communication is a profoundly social activity invo…lving interactions among groups or individuals, common standards of exchange, and national infrastruc tures to support telecommunications activities. The contributions of the invited speakers and others in this track begin to explore the social dimension of communication within the context of integrated, information systems for the public sector. Interactions among businesses and households are described by Ralf Strauss through the development within a real community of a 'wired city' with information and electronic services provided by the latest telecommunications technologies. A more specific type of interaction between teacher and student forms the basis of education. John Tiffin demonstrates how virtual classrooms can be used to augment the educational process. Carl Loeffler presents yet another perspective on interaction through the integration of A-life and agent technologies to investigate the dynamics of complex behaviors within networked simulation environments. Common standards for communication in the form of electronic documents or CSCW (Computer Supported Cooperative Work), according to Roland Traunmiiller, provide en abling technologies for a paradigm shift in the management of organizations. As pointed out by William Olle, the impact of standardization work on the future of information technology depends critically upon the interoperability of software systems.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Aging is one of the most serious and costly health problems in the Western world. A disproportionate amount of the available health care capability is devoted to the health care of the aged and the cost of this care is soaring. Vie…wed in wide perspective, aging presents two problems for the researcher's consideration. First is that of providing the most efficacious therapeutic regi mens and the best possible care for those already in their latter years. The second is to determine the cause or causes for senes cence and all its attendant problems in order to decrease the im pact of senescence on general health and well being. This volume is aimed at examining possible relationships be tween biological time structure and aging and ways by which these interrelationships might be examined in terms of both the causes of senescence and the management of health problems of the elderly. The purpose of the volume is to stir the interests of chronobiolo gists in gerontology and those of gerontologists and geriatricians in chronobiology. 356 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This comprehensive treatise on the reticuloendothelial system is a project jointly shared by individual members of the Reticuloendothelial (RE) Society and bio medical scientists in general who are interested in the intricate syste…m of cells and molecular moieties derived from these cells which constitute the RES. It may now be more fashionable in some quarters to consider these cells as part of what is called the mononuclear phagocytic system or the lymphoreticular system. Nevertheless, because of historical developments and current interest in the subject by investigators from many diverse areas, it seems advantageous to present in one comprehensive treatise current information and knowledge con cerning basic aspects of the RES, such as morphology, biochemistry, phylogeny and ontogeny, physiology, and pharmacology as well as clinical areas including immunopathology, cancer, infectious diseases, allergy, and hypersensitivity. It is anticipated that by presenting information concerning these apparently heterogeneous topics under the unifying umbrella of the RES attention will be focused on the similarities as well as interactions among the cell types constitut ing the RES from the viewpoint of various disciplines. The treatise editors and their editorial board, consisting predominantly of the editors of individual vol umes, are extremely grateful for the enthusiastic cooperation and enormous task undertaken by members of the biomedical community in general and especially by members of the American as well as European and Japanese Reticuloendothe lial Societies. 788 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The conference entitled 'The Translational Apparatus' was held in Berlin from October 31 to November 5, 1992, in honorem et memoriam of H. G. Wittmann. The presentations of the rewarding, enjoyable and scientifically exciting week…in Berlin were a fitting appreciation of this great man, and all participants and speakers contributed to the success of the meeting. The second reason for holding the Berlin meeting was to convene a group of scientists for a state-of-the-art presentation on ribosomes and related subjects; the outcome is this book. We have broadened the spectrum of topics to cover activities preceding and following pure ribosomal functions, such as 'Synthetases' and 'Protein Sorting', respectively, and we took the liberty of ordering the contributions in a way which does not always reflect the order of speakers. We are grateful to the authors who patiently tolerated our organization and our regulations for manuscripts. K.H. Nierhaus F. Franceschi A.R.

Taschenbuch. Condizione: 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 overrejectio…n 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. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Volume V deals with the problems of turnover in the nervous system. 'Turnover' is defined in different ways, and the term is used in different contexts. It is used rather broadly in the present volume, and intentionally so. The tur…nover of macromolecules is only one aspect; here 'turnover' in dicates the simultaneous and coordinated formation and breakdown of macromolecular species. The complexities of cerebral protein turnover are shown in a separate chapter dealing with the synthesis of proteins, in another on breakdown, and in still another on the relationship of these two (showing how the two halves of turnover are controlled). The fact that most likely the two halves of protein turnover, synthesis and breakdown, are separated spatially and the mechanisms involved are different further emphasizes the complexity of macromolecular turnover. 'Turnover' is used in a different context when the turnover of a cycle is discussed; but here again a number of complex metabolic reactions have to be interrelated and controlled; some such cycles are discussed briefly in this volume, additional cycles have been discussed with metabolism, and some cycles still await elucidation or discovery. 480 pp. Englisch.

Taschenbuch. Condizione: 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 Howev…er, 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. Condizione: 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 integr…ated 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.

Taschenbuch. Condizione: 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 o…f 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. Condizione: 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-estab…lished 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.

Taschenbuch. Condizione: Neu. 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.

Taschenbuch. Condizione: Neu. 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 shel…ved. 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.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Assembly of 'difficult' components onto printed circuit boards is emerging as an important application area for small, fast industrial robots. For other robot tasks - for example paint spraying or arc welding - the applications eng…ineer can rely on a body of published information representing decades of accumulated knowledge about the actual process being automated. But for the process of assembly relatively little systematically presented knowledge exists, mainly because so much manual assembly depends on extremely subtle co-ordination of hand, eye and brain which is hard to represent directly in engineering terms. As for the particular processes of electronic assembly, they have hardly been covered at all in the literature. Yet the design of a good PCB automation system depends crucially on the responsible engineer fully understanding every aspect of the process he or she is automating, whether working for the electronics manufacturer, an automation company, a research laboratory or a machine builder. The author of this book has had extensive practical experience in all these roles: as a source of great detail on most aspects of the electronic assembly process it will be of unique value not only to the robot specialist but well beyond that to anyone needing to understand how printed circuit boards are manufactured. P. G. Davey Acknowledgements The author is indebted to many companies and individuals from within the pcb assembly industry. 216 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The stream of our consciousness contains an almost unceasing parade of sensation-like experiences, even in the absence of any external stimulation to produce them. We experience picture-like things, sound-like things, and more; our… experiences can resemble any of our sense modalities. These experiences are what we refer to by the phrase 'mental imagery.' The images need not be vivid. People who doubt that they experience visual imagery are often persuaded by a simple exercise: count the windows of the house in which you live. Nearly everyone performs this task by walking around the house in imagination while counting windows, or by walking through the house counting them from the inside. The imaginary windows seem to be set in visual space. There is a temptation to point at them with an index finger while one counts, even though the images may never become vivid enough to seem like an actual visual experience. But if they seem set in visual space, if they can be pointed at, they clearly constitute a sensory-like experience in some meaningful way. 412 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -I do not think of myself as primarily interested in method, but in the substance of psychology. Nevertheless, our discipline has such difficulties in coming to grips with its substance that I have found myself getting involved in f…ww 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.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Enzyme technology continues to maintain a high degree of interest both in the academic and industrial communities. Since the last Enzyme Engineering Conference held in Bad Neuenahr, Federal Republic of Germany, two years ago, an in…creasing emphasis has been placed on the study and application of immobilized whole cells and organelles. This new emphasis has been reflected in the number of presentations directed to this area. The Fifth International Enzyme Engineering Conference was held in Henniker, New Hampshire, July 29 to August 3, 1979. The organizers of this conference are especially grateful for the generous support received from a number of industrial organizations. The conference was attended by 183 participants representing over 22 countries making this truly an international conference. During this conference, emphasis was placed on a wide variety of areas including: enzyme production, energy transduction, co factor modification, biomass conversion, immobilized enzymes, cells and organelles, and enzymatic synthesis of chemicals and pharma ceuticals. This volume contains most of the presentations and posters presented at the Fifth Conference. The names of the session co chairmen, workshop chairmen, committee members and sponsoring organizations are included as an appreciation of their efforts in making this a successful conference. The preparation of this volume was carried out by the editors including editing and proofing of the individual manuscripts and the final copy of this volume. The editors are indebted to Ms. S. 504 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The primary purpose of this book is to bring to the attention of members of the medical and scientific communities, as well as to other interested persons, a new and expanding area of investigation that features the use of chemical…s for the prevention of tumor induction and development. This novel use of chemical compounds has succeeded in producing a remarkable series of discoveries in recent years. Some of these are beginning to be evaluated in the field of clinical oncology in a manner that has potentially enormous public health implications. It is anticipated, therefore, that increasing amounts of time, energy, and financial resources will be devoted to the further development and expansion of this work. The major contribution of this book at the present time is that it summarizes and brings up to date the pioneering efforts of the various scientists who originated this new and exciting field of scientific activity. The thoughts expressed by Louis Pasteur in 1884 may soon be applicable in the fight against cancer: 'When meditating over a disease, I never think of finding a remedy for it, but instead a means of preventing it. ' The emphasis on cancer prevention currently underway is the result, in part, of an increased awareness that the environment-geographical, cultural, and occupational-has a role in development of the disease. 248 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Radiography, the use of penetrating radiation to produce shadow images of the internal structure of materials, has been with us since Roentgen made his discovery of x rays in 1895. However, applications of radiography in the earth…sciences and in the related field of soils engineering have, until recent ly, been slow to develop. Bruhl reported optimistically on applications in paleontology as early as 1896 and there have been additional reports through the years. However, very few paleontologists adopted the method and the significant literature is relatively restricted. In soil mechanics, Gerber observed the movement oflead pellets in sand during a plate-bearing test as early as 1929. Gradual ly, radiography was applied to other tests including those on footings, compaction of soils, strain in sand, effects of pile penetration, and displace ments under moving wheel loads. Recently, such work has broadened into much varied and sophisticated research. Applications in geology may be dated to Hamblin's work on rocks re ported in 1962. His demonstration that many fine textural and structural details can be observed in slices of rock led to experimentation by others on unconsolidated sediments and soils. Work is now expanding at an un precedented rate. In some operations, such as the logging of oceanographic cores, it is already a routine process. The advantages of radiography lie in its nondestructive nature and its ability to reveal features that sometimes cannot be seen in any other way. 172 pp. Englisch.

Taschenbuch. Condizione: 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. Condizione: 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 biolog…ical 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. Condizione: 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 annua…l 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. Condizione: 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.
