Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -With a jolt you pull your car to the side of the road, and read the job sign that can't be over one day old: New Home of ABC Inc.; General Contractor, XYZ Construction Co. You think out loud, 'I knew the property had been sold,' and your eyes roam over the real estate sign with the angled 'sold' sticker pro claiming to all that the agent has been successful. 'Thought the job would have come out on the bid list by now,' you mutter as you move back onto the road and head for your office. Later in the day you get the agent on the phone: 'Jim, how did XYZ get the ABC job I saw nothing on the builders' exchange about it.' 'John, XYZ has been negotiating with ABC for the past six weeks. They did one fine job of selling on old McDuff. Understand they just called on him out of the blue asking for a chance. They put the whole package together, plans and all.' 'Didn't that tightwad McDuff get another price, Jim ' 'Sure did; two, as a matter of fact. He asked me to get two other contractors capable of doing design-build projects. He liked XYZ better. I don't know the prices, but I really feel those boys impressed McDuff by going to him. Were you planning to bid the job ' 'Thinking about it,' you answer, trying to sound very casual. 200 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The wish for a child runs deep, as does the desire for parenthood. It is a wish that is essential to the continuance of the human species. It derives its motive power from many interrelated sources: psychobiological, sociological, historical. Yet it is a power that is changing hands. A short decade ago, Louise Brown was born. Prior to this event, human beings had begun biological life deep inside a female body. Louise Brown's birth signaled the beginning of a new era: The door to a new biotechnological world was opened, a world of artificial insemination, in vitro fertilization, surrogacy, embryo transplants, amniocentesis, gender preselection-procedures imagined but never before realized, leading perhaps to the injection of new genetic material into frozen embryos. Indeed, what had been, since Eve, an exclusively female power and prerogative has now been invaded by 20th-century biotechnology. The womb has been replaced, and sperm and egg can now be joined without love and romance. Change brings with it new questions: A complex inquiry has been generated by issues that are psychological, ethical, moral, biological, sociological, and legal. Simultaneously, and not incidentally or accidentally, gender psychology is in transi tion. As we enter an androgynous zone, cultural heroes shift, new couples emerge. Gender roles are redefined, and renegotiated, not without struggle and apprehen sion. We are approaching a new frontier-hopeful, self-conscious, and anxious. The possibilities are endless, as are the problems. 332 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Society has historically not taken a benign view of genetic disease. The laws permitting sterilization of the mentally re tarded~ and those proscribing consanguineous marriages are but two examples. Indeed as far back as the 5th-10th centuries, B.C.E., consanguineous unions were outlawed (Leviticus XVIII, 6). Case law has traditionally tended toward the conservative. It is reactive rather than directive, exerting its influence only after an individual or group has sustained injury and brought suit. In contrast, state legislatures have not been inhibited in enacting statutes. Many of their products can be characterized as hasty, unnecessary, ill-conceived, and based on the heart rather than the head. Moreover the lack of expert consultation sought has also been remarkable. One state legislature, for example, has advocated immunization for sickle cell anemia! Many others have enacted laws for the screening of inborn errors of metabolism, e.g., phenylketon uria, but have poorly defined the lines of responsibility to secure compliance. A spate of specific disease-related bills has emerged in the u.S. Congress, each seeking recognition and appropriations. Sickle cell anemia, hemophilia, Cooley's anemia and Tay-Sachs disease have been among the front-runners for support. Finally, in 1975, Congress has begun to examine an omnibus bill concerning all forms of genetic disease. The bill, termed the National Genetic Diseases Act is, however, still far from being enacted. 548 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The aim of this book and the rationale behind writing it are twofold, and are born of experience in working in the field with geologists, builders, land scapers, and people in the construction and building trades in general. This author, in his capacity as a geologist, air photo interpreter, and surveyor, has been asked to consult on very simple tasks that should be a part of the general knowledge of nearly everyone in the building trades. There is a definite and clear need for a short, simple, well-illustrated, and concise book that treats problems encountered every day by people in the field, and for training such people. This is such a book. The primary aim of the book, then, is not to write about new knowledge in the areas of photogrammetry or mathematics, or to discuss the latest procedures in using complex electrooptical surveying devices, but to give the common, everyday worker in the field (and there are many of them) some assistance and guidance. 280 pp. Englisch.

He has blond hair and blue eyes, weighs 150 pounds, and is five feet eleven inches tall. He was arrested in California at age sixteen for assault and robbery. Because he was underage he was initially segregated in a one-man cell while in county jail. Then, upon admission to a state prison recep tion and classification facility, he was housed in a special dormitory for young, inexperienced inmates who would be at risk within the general population. Upon completion of his screening Barry's counselor recommended that he be sent to a penal institution reserved for the younger, more violence-prone, and hard core inmates. Barry said that he felt he would have 'prob lems' at the recommended facility, but his counselor replied, 'You won't have any problems.' Once he arrived, Barry was double-celled with a nineteen-year-old inmate who beat and anally raped him during his first night in the admission unit. Barry's cellmate continued to assault him sexually during the two weeks they were housed together. 276 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Technology is not an end in itself, but a way of satisfying human wants. It shows us how to solve the age-old economic problem of surviving and pros pering in a hard world. But to optimize the benefits of technological advance requires an understanding of how it happens. The purpose of this book is to provide some of that understanding. The subject is so enormous and so intertwined with every human activity that a small selection of it, and that from a special viewpoint, is inevitable. The selection of subject matter has been, of course, conditioned by what interests me and is somewhat heterogeneous. However, it is connected by two major themes. The first is that it emphasizes the dynamic nature of technology, in the sense that it must be approached as a process evolving in time that can often be described in quantitative terms. The second is that I have chosen topics that I believe are essential for a strategic sense of how to plan for, execute, and respond to technological change. These two themes complement each other because the strategic sense requires an appreciation of the dynamics and the dynamics naturally lead to a consideration of how to deal with technology so that it can be used to achieve human objectives. The unifying thought behind the book is that technological change has a systemic as well as an idiosyncratic aspect. 548 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Until the early to mid-1970s, social scientists in the fields of population and development were largely going their own ways. Demographers relied almost exclusively on demographic transition theory as their para digm for understanding the role of development in population change and fertility decline. Conversely, most development economists and other specialists were certainly aware of the constraints placed upon development objectives by population growth. However, the main de velopment theories paid little attention to population and the implica tions of population growth for development. Indeed it was not until after the World Population Conference in Bucharest in 1974 that the interaction of population and development became a serious and pur posive theme for social scientific study. Accordingly, since about the mid-1970s, an extensive literature in the field of population and develop ment has been generated. And in 1975, under the auspices of The Popu lation Council, the journal Population and Development Review was found ed, a journal which in the past decade has developed into the premier publication in the world for work in this area. But our understanding of development as it refers to change in Third World countries remained fragmented. Moreover, our understanding of the linkages and interac tions between population and development was very limited. It is in this regard that Ozzie Simmons's Perspectives on Development and Population Growth in the Third World will certainly have an impact. 296 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Giving on occasions a talk on the subject of this book, one of the queries raised was, 'surely, what you mean are flat hierarchies'. This, I think, gives an indication of how difficult it can be to conceive of organizations which do not have a hierarchical structure. A rather similar response was obtained when, in the 1950's, an account was given to a manager of the British Coal Board of an autonomous composite team of more than 40 miners, who had taken over complete responsibility for a three-shift cycle, and divided the income obtained among themselves. His comment was that this could not possibly work. The new mode of work organization which had been evolved by the miners in several pits in the Durham coal fields was, at the time, well ahead of the prevailing concepts and philosophy of both management and the Trade Union. It did not help matters very much that the detailed accounts were presented in an academic and scientific form (Trist et aI. , 1963; Herbst, 1962). I think that we felt that all the backing of systematic research and data analysis would be needed to present the case for modes of organization, which deviated from conventional practice. However, something was learned from this experience. When at the beginning of the 1960's the Norwegian Work Democratization Project was started, a number of demonstration sites were set up which people could look at, and which could function as centers for diffusion. 124 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -I am pleased to introduce this volume on Myoblast Transfer Therapy on behalf of the Muscular Dystrophy Association and all of its Advisory Committees. The international conference which led to this volume brought together leading basic scientists and clinical investigators for the purpose of coordinating the development of this new field in the fight against muscular dystrophy. The Muscular Dystrophy Association is the nation's most rapidly growing voluntary health agency in terms of its programs of patient care, research, and professional and public education. Success is attributable to its National Chairman, Jerry Lewis, to its effective corporate membership, and to the many physicians and scientists who give their time freely to advise on policies, to review grant applications, and to participate in meetings such as this. I should like to acknowledge a large number of other individuals to whom we are indebted: the broad segment of the American public which continually and generously supports our spectrum of services. The Muscular Dystrophy Association, next year, should raise in excess of $115,000,000. These contributions are derived from more than 10 million American families. These families are not only pledging their money but expressing their hopes that we will find answers to the tragic problem of neuromuscular disease. We are confident that the fruits of this meeting will move the frontier of research forward toward that goal. 332 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -During the past several decades, much research effort has gone into the elucidation of the role of neuroendocrine systems as secretory and metabolic regulators of cells of a variety of organs and structures, including the testes, ovaries, adrenals, thyroid, pituitary gland, and mammary glands. However, the role of cells comprising such organs and structures in the modulation of neuroendocrine processes has received considerably less is generally less well appreciated. attention and Nonetheless, it is important that we understand the actions on neuroendocrine systems of substances that reach the brain by way of the vasculature, including hormones, cytokines, toxins, amino acids, drugs, and similar agents. In order to analyze the present state of knowledge on this topic, experimental scientists and clinicians, whose shared interests include actions of circulating agents on the brain, met at a satellite symposium of the XXXI International Congress of Physiological Sciences. This symposium, entitled Circulating Regulatory Factors and Neuroendocrine Function, was held in Smolenice Castle, Czechoslovakia, June 26-July 1, 1989, and reviews delivered at this symposium as invited presentations are published in this volume. Presentations given as free communications have been published separately and are available in Endocrinologia Experimentalis 24: 1-273, 1990. 508 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -It is very rewarding for an author to know that his book is to be translated into another language and become available to a new circle of readers. The study of the optics and spectroscopy of activated crys stals has continued to grow. The development and first remarkable successes of light scattering by impurities in crystals have occurred in the comparatively short time since my original book was sent to press. After experimental observation of the sidebands (wings) in impurity infrared absorption spectra, interest in these spectra as a source of information on the vibrations of a crystal in the neigh borhood of an impurity has increased significantly. Therefore, in addition to making minor corrections, r have supplemented the section on the effect of anharmonicity (section25) and written two new sections and another Appendix on infrared ab sorption, scattering of light by an impurity center in a crystal, and the adiabatic approximation, respectively. The bibliography has received several dozen new entries, but it nevertheless does not pretend to be complete. r hope that the American edition is useful and in some de gree corresponds to the general deepening of our physical under standing of solids. 272 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The development of an effective method of drilling oil and gas wells to depths of 3-5 km and more is a complex problem of great practical interest. 'Deep Hole Drilling With Explosives' is a distinctive and very interesting work of the engineer A. P. Ostrovskii, who more than twenty years ago, by his original suggestions, made a start in investigating the field of so-called non-bit processes of shattering rocks when drilling holes, a.nd, with his co-workers, developed a fundamentally new explosive method of drilling deep holes. This book discusses the new trend in worldwide a.pplication of explosives in technology and the national economy; it presents considerable experimental material on the effect of explosions in solid media, material that is not only interesting to specialists in mining but also to physicists. Many phenomena discussed by the author and cited in the book still await explanation, but the fact that these phenomena have been already subjected to experimental study undoubtedly adds to our knowledge of one of the most meagerly investigated areas of the science of explosions-concerning the shattering effect of explo sions on solid media. July 29, 1960 Professor M. A. Sadovskii Corresponding Member of the Academy of Sciences of the USSR 1 INTRODUCTION Together with the perfection of turbine drilling and the introduction of electrical drills in the USSR, new methods have been developed for shattering rock and drilling deep oil and gas wells without the use of a bit. 140 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book is directed primarily to advanced graduate and medical students, postdoctoral trainees, and established investigators having basic research interests in neoplasia. Its content is based in part on the lecture outlines and selected histopathology laboratory components of an advanced course entitled The Pathobiology of Experimental Animal and Human Neoplasia, developed by me for the Experimental Pathology Curriculum of the Department of Pathology at the Medical College of Virginia. In this regard, an effort has been made to integrate pathology with carcinogenesis, genetics, biochemistry, and cellular and molecular biology in order to present a comprehensive and current view of the neoplastic process. For focus, emphasis is mainly being placed on the neoplastic cells themselves, and not on associated host-mediated responses. It ishoped that this book will accomplish its purpose of providing students and researchers who already possess strong but diverse basic science backgrounds with unifying concepts in tumor pathobiology, so as to stimulate new research aimed at furthering our understanding of neoplastic disease. I wish to express my appreciation and heartfelt thanks to the authors, whose individual ranges of expertise and research experience clearly bring to their respective chapters unique perspectives that easily transcend any redundancy that may be present. In addition, I am grateful to Drs. George Vennart, Saul Kay, and Fred Meier, and to Ms. Connie Wilkerson of the Department of Pathology at MCV, for their helpful comments and their review of some of the material. 608 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -My ideas for this book have been evolving over the last several years as I have been working in the animal modeling area and have seen it change rather dramatically. There have been tremendous advances, both in methodology and in conceptualization, yet the literature is scattered in journals encompassing many disciplines. In particular, there have been only very limited attempts to write about the philosophical, conceptual, and controversial issues in this field; to pull together diverse findings; and to provide some general perspective on its future. As will probably be apparent, I am a clinical psychiatrist who also has a fundamental interest in animal behavior, especially primate social behavior. I entered the field from a clinical research standpoint to devel op some animal models of depression after being stimulated to do so by Dr. William Bunney, then at the National Institute of Mental Health and now at the University of California-Irvine. The field has grown rapidly since then and there is considerable research activity. Indeed, the re search activity has grown more rapidly than our conceptualization of what animal models are and are not. Animal preparations are now available for studying specific aspects of certain types of psychopathology. Thoughtful workers in the animal modeling field no longer talk about comprehensive models but rather about more limited experimental preparations in animals for studying certain specific aspects of human psychopathology. 216 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The study of the relationship between environmental pollution and human health is in its infancy. The number of substances and mixtures that have been identified in uncontrolled hazardous waste sites or that have been in advertently released into the environment is large and data on how thes~ substances are modified as they interact with one another as they migrate through soil, air, and water are limited. There are also limits on our un derstanding of how these substances may be ingested, inhaled, or absorbed by people. The complexity of possible interactions between biological, chemical, and physical components in a given environment makes it virtually impossible to evaluate the potential for adverse biological effects ade quately in the laboratory. Other, more comprehensive methods which provide realistic and interpretable results must be used. Many scientists believe that humans represent the ultimate sentinel species of a toxic exposure re sUlting from environmental pollution, however such exposures may also se verely impact environmental health. There exists a wide variety of organ isms in the natural environment that could be used to provide an early warning for potential human health effects as well as to indicate adverse ecological effects. The issue of effective utilization of sentinel species for environment al monitoring is a rapidly developing area of research which has grown in importance during the last decade. 288 pp. Englisch.

Delegates from seventeen countries attended. This Symposium was initiated through an EEC Stimulation Program. The formal program included forty verbal presentations by invited speakers and sixty miniposter presentations, and was formulated by the Organizing and Scientific Committee: E. Carmeliet (Leuven), J. P. Collin (Poitiers), S. Forsen (Lund), C. W. Heizmann (Ziirich), D. E. M. Lawson (Cambridge), P. Miroir (Brussels), J. L. Pasteels (Brussels) and R. Pochet (Brussels). This volume contains the papers prepared by the invited speakers. The contributions are grouped according to their general subject matter: Genes of Calcium-Binding Protein Family, Structure/Function Relationships, The Cytoskeleton and Calcium-Binding Proteins, Calcium-Binding Proteins in TransforlIled Cells, Calcium/Lipid-Binding Proteins, Calcium-Binding Proteins Substrates and Immunohistochemistry of Calbindin and Calretinin. The highlights of the symposium are numerous. Among the items to be noted are the growing number of abundant proteins which interact with calcium and sometimes with other second messenger sys tems; specifically pH associated with the tyrosine kinase calpactin, calcYclin, p9Ka induced by growth fac tors, MRP-8 and MRP-14 (also called cystic fibrosis antigen, L1 or calgranulins) forming half the soluble protein of granulocytes. New structure/function relationships on calbindin D9K and calmodulin have emerged from nuclear magnetic resonance and site-directed mutagenesis studies. 228 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -After thousands of clinical trials, the efficacy of psychotropic drugs in the treatment of psychiatric disorders has become well established. However, the very success of these drugs has meant that many patients with chronic illnesses will receive them for a significant part of their lifetime. Side effects and other adverse reactions are an unfortunate but unavoidable component of successful pharmacotherapy. In deed, the main emphasis in new drug development is often on the search for compounds that have fewer side effects, although no one has as yet found an effective drug without them. Therefore, it is important for clinicians to be aware of side effect reaction profiles, because they are often a major determining factor in the choice of therapy. After more than three decades of major breakthroughs in the development of psychotropic drugs, reactions to these medications are still frequently reported in the current liter ature, and information about well-known reactions is con stantly refined. This book is an attempt to systematically collect and organize this large body of data and present it in an easy-to-use form. All chapters follow the same reaction oriented logic, and each important reaction is discussed using the same consistent subdivisions. The more clinically impor tant reactions appear in the body of each chapter; the more unusual or rarely reported reactions are briefly characterized in the miscellaneous section at the end of each chapter. 188 pp. Englisch.

Although seemingly simple, these experiments tackle a very complex subject with which psychologists, linguists, and others are only beginning to come to grips. Sokolov and his group have succeeded admirably in splitting the subject apart by driving in the wedges of objective measurement and unique experimental formulations. Chapter IX dips into the neurology and neurophysiology of motor speech and its feedback mechanisms and the dynamic localization and organization of the cerebral mechanisms responsible for symbolic formulation of speech and thought. The bibliography brings together a considerable number of Russian publications on this subject, as well as some of the pertinent American and European literature.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -IS THE TOPIC ANALOG TESTING AND DIAGNOSIS TIMELY Yes, indeed it is. Testing and Diagnosis is an important topic and fulfills a vital need for the electronic industry. The testing and diagnosis of digital electronic circuits has been successfuIly developed to the point that it can be automated. Unfortu nately, its development for analog electronic circuits is still in its Stone Age. The engineer's intuition is still the most powerful tool used in the industry! There are two reasons for this. One is that there has been no pressing need from the industry. Analog circuits are usuaIly small in size. Sometimes, the engineer's experience and intuition are sufficient to fulfill the need. The other reason is that there are no breakthrough results from academic re search to provide the industry with critical ideas to develop tools. This is not because of a lack of effort. Both academic and industrial research groups have made major efforts to look into this problem. Unfortunately, the prob lem for analog circuits is fundamentally different from and much more diffi cult than its counterpart for digital circuits. These efforts have led to some important findings, but are still not at the point of being practicaIly useful. However, these situations are now changing. The current trend for the design of VLSI chips is to use analog/digital hybrid circuits, instead of digital circuits from the past. Therefore, even Ix x Preface though the analog circuit may be small, the total circuit under testing is large. 304 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The electron theory of solids has attracted great attention in recent years, mainly because of the numerous practical applications of semicon ductors. However, all the reviews and monographs on this subject deal only with crystalline conductors. At present, mainly in the Soviet Union, experi mental and theoretical investigations have been extended to liquid and solid amorphous conductors, and in particular to such semiconductors. However, all the work published so far in this field is in the form of separate papers scat tered throughout various journals, and there has as yet been no Soviet or for eign review of the theoretical work on amorphous semiconductors, in spite of the increasing interest in them. The investigation of liquid and amorphous semiconductors is of great practical importance, first, because all the solid semico'nductors are usually prepared from the liquid phase and it is important to know the electrical and other properties of this phase; secondly, amorphous semiconductors are beginning to be used in industry, for example, amorphous Sb S films in vidicon tubes. In some cases, especially in optical instruments, 2 S amorphous semiconductors have advantages compared with crystals. Theore tical studies of amorphous semiconductors should help in these practical applications. The present monograph is the first attempt to present systematically the quantum electron theory of amorphous conductors. The most interesting-in the author's view-theoretical papers on this subject, published in journals are reviewed and critically compared. 296 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Most standard texts in basic organic chemistry require the student to memorize dozens of organic reactions. This is certainly necessary to master the discipline. Unfortunately, most texts do not emphasize why these reactions occur and, just as important, why other reactions that might seem conceivable to the student do not occur. Without this understanding, students tend to forget what they have memorized soon after the course is over. It is the purpose of this book to familiarize the student with the principles governing organic reactivity and to provide a 'feel' for organic chemistry that is impossible to secure by memory alone. Digesting the ideas in this book will, we hope, not only explain the common organic reactions but also allow the student to predict the prod ucts and by-products of reactions he has never seen before. Indeed, the creative student might even become capable of designing new reactions as might be required in a complex organic synthesis. In Chapter 1, we cover the basic principles including bonding, nuclear charge, resonance effects, oxidation-reduction, etc. It is a brief discussion, but it nonetheless provides the basis for understanding reaction mechanisms th~t will be treated later on. We highly recommend that this material be reviewed and that the v VI PREFACE problems be worked at the end of the chapter. Answers are given to all problems. In Chapter 2, reaction mechanisms are presented in an increas ing order of difficulty. 228 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Only a small part of the numerous photochemical reactions in organic compounds result in reversible structural changes. The latter are accom panied by a change in physical properties, in particular, of electronic spectra. It is tempting to try to use this photochromic effect in various systems for controlling and regulating light fluxes and for data recording. Eventually an independent trend emerged in photochemistry - the study of the photochromism of organic compounds to establish relationships between structure and photochemical behavior, the theoretical analysis of these relationships to predict structures with pre-set photochromic parameters, and, finally, the identification of suitable areas for the application of photochromism. This monograph summarizes the results of recent studies carried out by a number of research institutions in the USSR and the GDR. Devoted to an important aspect of applied photochemistry, this monograph contains a detailed exposition of the chemical photochromes referred to briefly in the earlier editions of 'Introduction to the Photochemistry of Organic Compounds' (Khimiya Press, Moscow, 1976) and 'Photochemical Proces ses in Layers' (Khimiya Press, Moscow, 1978). 284 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Physical and spectroscopic methods have been used jointly for characterization of polymers for at least four decades. Yet, new techniques permit increasingly refined determination of polymer chemistry and morphol ogy_ The correlation of this knowledge with physical properties of polymers is helpful to planned synthesis of new products. The most prominent spectroscopic techniques through the forties and fifties were infrared and ultraviolet spectroscopy. Nuclear magnetic resonance, electron spin resonance and MOssbauer spectroscopy started making sig nificant contributions to polymer chemistry in the early sixties. Still more recently fluorescence spectroscopy and laser Raman spectroscopy have become readily appli cable to polymers and are contributing significantly to the understanding of the relationship between polymer structure and properties. Determination of the distribution of monomer se quences by molecular size has become possible through combined gel permeation chromatography and spectroscopic analysis. Fragments of polymers from chemical break down or from pyrolysis are further fractionated and structurally analyzed. The relationship between the chemistry of polymers and performance can be determined from changes in chemical structure and orientation after curing, degradation, or physical or thermal manipulation of the polymers. 292 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This set of lectures is the outgrowth of a new course in the Department of Materials Science at Stanford University. It was taught collectively by the authors of the various sections and represents an attempt to increase the awareness of students in the materials area of computer simulation techniques and potentialities. The topics often ranged far afield from the materials area; however, the total package served the intended purpose of being an initiation into the world of computer simulation and, as such, made a useful first iteration to the intended purpose. The second iteration, which is in process, deals exclusively with the materials area. The course was designed to teach students a new way to wrestle with 'systems' problems in the materials science work area that require the synthesis and interactions of several disciplines of knowledge. This course was a response to the realization that effective handling of real problems, which are essentially systems problems, is one of the most important at tributes of a graduate materials scientist. About a third of the course was devoted to the student's selected problem, in the materials area, which he simulated using the digital computer. 236 pp. Englisch.

We are specially grateful to the Board of Directors of the Wenner-Gren Foundation for Anthropological Research for the award of a symposium on Physical Anthropology and Nutritional Status. We had considered that such a subject was timely and that an inter-disciplinary approach would contribute useful knowledge in a most important area--particularly in the field of child health. This pUblication of the proceedings will show the degree of success of these aims. Mrs. Lita Osmundsen, Director of Research at the Wenner-Gren Foundation, not only steered us in the early stages but, during our delightful time at Burg Wartenstein, and subsequently, she has been that most charming of crosses--den mother and first class science administrator. We are deeply grateful to her. And grateful, too, for the organization and friendly warm spoiling by the Wenner-Gren staff in residence at Burg Wartenstein. Our nutritional status was high.

In spite of the fact that diseases such as polio myelitis and measles have been controlled in the industrialized countries by vaccination, vaccines now in use in tropical countries have proved not to be optimal. Further research is needed to develop new vaccines that will be effective in all countries. To do so we need to understand better the immune response to different viruses so that we may be able to maxi mize the protective response of new vaccines and minimize their potential immunopathologic effect. An exciting new discovery which is now being further developed is the possibility of being able to use some viruses (e.g. vaccinia, adenoviruses, etc.), as carriers for other antigens. This may open up the way for the production of vaccines that will be inexpensive and that will confer long lasting immunity after only one injection. This meeting has also served to review our present knowledge of virus diseases which are still of great importance such as hepatitis, dengue and influenza. 320 pp. Englisch.

I. Vernadskii and A. E. Fersman [1, 2J. Vernadskii considered geochemistry to be the science of the history of chemical elements on the earth, their distribution and move ments in space and time, and their genetic relations [IJ. Geochemical migration was defined by Fersman as 'the movement of chemical elements in the earth's crust leading to their dissemination or concentration. ' The views of Vernadskii and Fersman on the migration of elements have received added support and development in connection with successes in physics, chemistry, biology, and other sciences. According to Fersman, the earth is looked upon as a cosmic body, characterized by common origin and Similarity of composition with the sun, the planets, meteorites, and other bodies of the solar system. The scale and trend of geochemical migration of elements in the earth are determined by the initial state of terrestrial matter, its thermal history, and the scale of time. The rules of elemental migration are determined by internal and exterual fac tors. Fersman distinguishes five groups of internal factors, i. e. 164 pp. Englisch.

Br. (FRG) during Oct tober 6-8, 1988. The meeting was held on the occasion of opening the new dialysis unit of the University Hospital of Freiburg i. Br . The topics discussed included membrane biocompatibility, catabolic factors associated with dialysis therapy, phar macological therapy in dialyzed patients, erythropoietin and renal anemia, new developments in CAVH, CAPD and plasmapheresis, renal replacement therapy in acute renal failure, and plasmapheresis therapy in systemic diseases. It was unfortunately impossible in this volume, to include the extended, lively and stimulating discussions which were enjoyed by the participants during the conference. The meeting has provided an unique framework for close interaction between scientists from various disciplines, including nephrology, pharmacology, hematology, cardiology, anesthesiology, surgery, intensive care medicine, and patho logy. We would like to express our gratitude and appreciation for all those who have stimulated, encouraged and supported us to hold the symposium in Freiburg.

This item is printed on demand - it takes 3-4 days longer - Neuware -This volume is based on an international symposium held during September 9-12, 1986 in Bocca di Magra, Italy. The intent of the organizers was to bring together expert practitioners of fluorescence spectroscopy, particularly as applied to biological systems, to assess recent developments in the field and discuss future directions. At the same time the meeting was intended to honor the singular and outstanding scientific career of Gregorio Weber on the occasion of his seventieth birthday. Gregorio Weber is truly the pioneer in the application of fluores cence methods to biochemistry and biophysics. A complete list of his scientific contributions to fluorescence and to protein biochemistry is beyond the scope of this preface. Suffice it to say that since his initial landmark articles on fluorescence, published in the late 1940's and early 1950's, Gregorio Weber has continued to make seminal contribu tions to both the theory and practice of fluorescence and, contrary to many who might be tempted to rest on their laurels, he shows no signs of slackening his pace. In addition to his more obvious tangible contributions to the scientific field, Gregorio Weber has made equally valuable contributions of another type. Specifically, he has had the most profound impact, both profeSSionally and personally, on generations of young scientists. 476 pp. Englisch.
