Taschenbuch. Condición: Neu. Neuware -Automation has been employed for many years to provide a multitude of reasonably priced products for the American consumer. However, it has become evident that its real character as a manufacturing systems approach needs to be examined carefully for a better appreciation. In this book the purpose is to examine automation technology in its broadest sense and develop not only an understanding but also present some of the engineering and organization 'know-how' by which manufacturing management can more effectively utilize automation to improve pro ductivity and combat rising costs in the years ahead. Fundamentally, this book is addressed to manufacturing managers, and the material presented in a manner that will provide the knowledge for assuring success in automating. In addition, it highlights the man ufacturing research and long-range planning that will be required for creating the new manufacturing technology so necessary for assuring success in future automation efforts. One of the important facts emphasized in this text is that automation is not merely robotics ar another kind or type of machinery. To effect true productivity improvement requires a fresh look at the entire pro duction process or facility-as a completely integrated system. With the developments of the past few years, rapid advances in the technology and the 'tools of automation' have brought this imperative goal within the reasonable grasp of manufacturing management in almost every segment of industry. However, to utilize this progress, it is necessary to acquire a working understanding of all facets of automation.…

Taschenbuch. Condición: Neu. Neuware -This book is intended to present group representation theory at a level accessible to mature undergraduate students and beginning graduate students. This is achieved by mainly keeping the required background to the level of undergraduate linear algebra, group theory and very basic ring theory. Module theory and Wedderburn theory, as well as tensor products, are deliberately avoided. Instead, we take an approach based on discrete Fourier Analysis. Applications to the spectral theory of graphs are given to help the student appreciate the usefulness of the subject. A number of exercises are included. This book is intended for a 3rd/4th undergraduate course or an introductory graduate course on group representation theory. However, it can also be used as a reference for workers in all areas of mathematics and statistics. 172 pp. Englisch.…

Taschenbuch. Condición: Neu. Neuware - Risk theory, which deals with stochastic models of an insurance business, is a classical application of probability theory. The fundamental problem in risk theory is to investigate the ruin possibility of the risk business. Traditionally the occurrence of the claims is described by a Poisson process and the cost of the claims by a sequence of random variables. This book is a treatise of risk theory with emphasis on models where the occurrence of the claims is described by more general point processes than the Poisson process, such as renewal processes, Cox processes and general stationary point processes. In the Cox case the possibility of risk fluctuation is explicitly taken into account. The presentation is based on modern probabilistic methods rather than on analytic methods. The theory is accompanied with discussions on practical evaluation of ruin probabilities and statistical estimation. Many numerical illustrations of the results are given.…

Taschenbuch. Condición: Neu. Neuware - What shall we say of this metamorphosis in passing from finite to infinite Galileo, Two New Sciences As its title suggests, this book was conceived as a prologue to the study of 'Why the calculus works'--otherwise known as analysis. It is in fact a critical reexamination of the infinite processes arising in elementary math ematics: Part II reexamines rational and irrational numbers, and their representation as infinite decimals; Part III examines our ideas of length, area, and volume; and Part IV examines the evolution of the modern function-concept. The book may be used in a number of ways: firstly, as a genuine pro logue to analysis; secondly, as a supplementary text within an analysis course, providing a source of elementary motivation, background and ex amples; thirdly, as a kind of postscript to elementary analysis-as in a senior undergraduate course designed to reinforce students' understanding of elementary analysis and of elementary mathematics by considering the mathematical and historical connections between them. But the contents of the book should be of interest to a much wider audience than this including teachers, teachers in training, students in their last year at school, and others interested in mathematics.…

Taschenbuch. Condición: Neu. Neuware - Estuaries exist along the edge of the oceans and seas, and are char acterized by the dilution of sea water by inflowing fresher waters. The motion and interaction of these two types of water (fresh and salt water) determine the salinity distribution within the estuary and that, in turn, affects the organisms residing there. The purpose of this vol ume is to review the status of our understanding of estuarine circu lation and how the circulation patterns affect living and nonliving resources in estuaries. For many years, the primary paradigm for estuarine circulation was the two-layered net or nontidal gravitational circulation pattern first proposed by Dr. Donald Pritchard in his studies of the James River estuary. During the last decade or so, research has focused on the many variations about this theme and the factors that control the transport processes. Many of these aspects are covered in the initial papers in this volume. Water movement, of course, is of interest be cause it transports marine organisms, sediments, and pollutants. Es tuarine circulation has a significant effect on estuarine food chains, and on the distribution and abundance of organisms, such as the American oyster, that are freely transported by the currents during larval stages. The intent is to bring together many of these topics in a single volume. This volume is dedicated to Dr. Donald W.…

Taschenbuch. Condición: Neu. Neuware - Developmental cancer products (oncodevelopmental markers, ODM) not only serve as diagnostic and prognostic indicators but also may be used to study the nature of the carcinogenic process and the biology of tumors. For many years oncologists have searched for markers of cancer cells that would permit unequivocal recognition of cancer in contrast to noncancerous tissue. The earliest and still most widely used method of identification of cancer tissue or cells is the structural resemblance of cancer tissue to fetal or immature tissue. Pathologists not only recognize cancer by its morphologic similarity to fetal tissues, but also in many instances can relate the behavior of a given tumor to the degree of tissue differentiation. Thus, poorly differentiated tumors that resemble fetal tissue generally grow more rapidly and metastasize earlier than do well-differentiated tumors that more closely resemble adult tissue. In recent years the commonality of fetal and cancer tissue has been extended to products of tumor cells that, can be analyzed by biochemical, immunological, or physiological techniques. Increas ingly, products of cancer cells similar to fetal products are being identified and studied. These products range from cell-surface markers (fetal or differentiation antigens), placental proteins, hormones, and isoenzymes to a multitude of products, such as carcinoembryonic antigen (CEA), alphafetoprotein (AFP), lymphocyte markers, and nucleic acids, such as tRNA, that are produced in small amounts by v vi PREFACE continually differentiating cells in the adult but in much greater amounts by tumors.…

Taschenbuch. Condición: Neu. Neuware - This book represents the proceedings of a Satellite Symposium of the XIth International Congress of Biochemistry on 'Control of Membrane Fluidity' which was held on July 7, 1979 at the Charles H. Best Institute, University of Toronto, Toronto, Canada. The meeting was organized by M. Kates and A. Kuksis and was supported by the International Congress of Biochemistry. The purpose of the meeting was to review recent progress in many different areas of investigation bearing on the role of lipids in the structural and functional property of the cell membrane commonly referred to as fluidity. The aim was to emphasize the factors controlling membrane fluidity as studied in appropriate in vitro and in vivo experiments. The Symposium included invited review papers and short papers offered by discussants. In assem bling the book no distinction has been made between the two types of presentations, nor has any significance been attached to the chronological order of their presentation in the Symposium. As a result it was possible to provide a much more coherent and continuous presentation than that available at the meeting.…

Taschenbuch. Condición: Neu. Neuware - The ability to diagnose cancer by simple measurement of a serum or tissue' 'marker' has been a goal of medical science for many years. There is ample evidence that tumor cells are different from normal cells and pro duce substances that can be detected by currently available immuno chemical or biochemical methods. These 'cancer markers' may be se creted proteins, enzymes, hormones, fetal serum components, monoclonal immunoglobulins, cell surface components, or cytoplasmic constituents. The purpose of this book is to present the current status of our knowledge of such cancer markers. The first tumor marker identified by laboratory means was Bence Jones protein. In a series of lectures delivered to the Royal College of Phy sicians in London in 1846, Dr. H. Bence Jones described studies on a urine sample sent to him with the following note: 'Dear Dr. Jones-The tube contains urine of very high specific gravity. When boiled it becomes slightly opaque . . . . etc. ' Dr. Jones found that heating of the urine after addition of nitric acid resulted in formation of a heavy precipitate; acid ad dition may have been required to bring the urine to pH 4-6 at which Bence Jones proteins are more likely to precipitate when heated. This urinary pre cipitate was associated with a bone disease termed 'mollities ossium. ' [H. Bence Jones, Papers on Chemical Pathology, Lecture III. Lancet 2, 269-274 (1847)].…

Taschenbuch. Condición: Neu. Neuware - This represents the third volume in a series on cancer markers pub lished by the Humana Press. The first volume, published in 1980, stressed the relationship of development and cancer as reflected in the production of markers by cancer that are also produced by normal cells during fetal development. The concept that cancer represents a problem of differentiation was introduced by Barry Pierce in describing differenti ation of teratocarcinomas. Highlighted were lymphocyte markers, alphafetoprotein, carcinoembryonic antigen, ectopic hormones, enzymes and isozymes, pregnancy proteins, and fibronectin. The second volume, published in 1982 and coedited with Britta Wahren, focused on the diagnostic use of oncological markers in human cancers, which were systematically treated on an organ by organ basis. At that time, the application of monoclonal antibodies to the identification of cancer markers was still in a very preliminary stage. A general introduc tion to monoclonal antibodies to human tumor antigens was given there by William Raschke, and other authors included coverage of those mark ers then detectable by monoclonal antibodies in their chapters.…

Taschenbuch. Condición: Neu. Neuware - During the last 10 years, the role of specific nutrients in cancer prevention and cancer treatment has been the subject of intense basic, preclinical, and clinical research. At present, the major focus of nutri tional oncology is on the mechanisms of carcinogenesis and their modification by nutrients and on cancer prevention studies in animals and humans. Some human epidemiological studies have confirmed the hypothesis, developed on animals, that there is an inverse relation ship between the intake and/or level of !3-carotene, vitamin A vita min E, or vitamin C and the risk of cancer, whereas others have shown no such relationship. This is not unexpected, since the protective effect of individual nutrients may be too small to be detected by epidemiological methodologies in which a single vitamin or mineral is considered as one variable. Conclusive evidence regarding the role of nutrients in human cancer prevention will come from a well designed human intervention study using one or more nutrients in a population that has a high risk of developing cancer. The involvement of specific nutrients in the regulation of protooncogene expression has just begun. Also, some of the results of human intervention trials are beginning to yield interesting results. A large number of interna tional scientists from various disciplines, including cell biology, mo lecular biology, nutritional oncology, epidemiology, and public health, reviewed and discussed their most recent findings. The following topics were emphasized: 1. Mechanisms of carcinogenesis; 2.…

Taschenbuch. Condición: Neu. Neuware - In organizing the present volume, we had two intentions. The first was to present the best current understanding of the mechanisms of calcium mobilization during excitation contraction coupling of smooth muscle at a level suited to the needs of professionals interested in smooth muscle pharmacology and pathophysiology, while remaining appreciable by graduate and medical students. The second intention was to provide in sight into present-day controversies, as well as the latest ad vances achieved by researchers in this field. Thus, we have thor oughly discussed both the techniques and the concepts derived from their application. An attempt has also been made here to answer a number of profoundly important questions: What are the mechanisms and agents responsible for the control of contractility What are the accompanying changes in the state of intracellular calcium ions and the mechanisms responsible for them How does the regula tion of contractility occur directly at the level of the actomyosin activity What role do gap junctions play in cell-to-cell coupling What are the roles of cholinergic, adrenergic, peptidergic, and nonadrenergic noncholinergic interactions in calcium mobiliza tion in smooth muscle What changes occur in hypertension The impact of these recent techniques on future research is also reflected upon.…

Taschenbuch. Condición: Neu. Neuware - Methods in Protein Sequence Analysis contains an intensely prac tical account of all the new methodology available to scientists carrying out protein and peptide sequencing studies. Many of the striking advances in fields as diverse as immunology, cell motility, and neurochemistry have in fact been fueled by our ever more powerful ability to determine the sequences and structures of key proteins and peptides. It is our hope that the rich array of tech niques and methods for sequencing proteins discussed in this volume-methods that generate much of the information crucial to progress in modern biology-will now become accessible to all who can benefit from them. The papers of the present volume constitute the Proceedings of the IVth International Conference on Methods in Protein Se quence Analysis, which was held at Brookhaven National Labo ratory, Upton, NY, September 21-25, 1981. It was the most recent in a series of biennial conferences, the previous one having been held in Heidelberg, GFR, in 1979. The series was originated by Richard Laursen, and initially dealt with one aspect of the field, solid-phase sequencing. The scope of the meeting was very broad and among the many aspects of protein sequencing discussed were: instrumentation, strategy, chemicals, mass spectrometry, cleavage of proteins and separation of peptides, and solid, liquid, manual, and even 'gas phase' sequencing.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -It is an honour for me to be asked to contribute a foreword to the book of my friends Therese and Ralph Spitzer. I got to know them during an assignment as Visiting Professor at the University of British Columbia at Vancouver, and I have shared to the full the distress that comes to all those who have to watch people that they love affected by mental illness in one form or another. I have been an orientalist for only half my life; for the first half I was a biochemist, embryologist, and experimental morphologist. 'When I, a young man, was called to the bar' (as Gilbert & Sullivan have it), in other words, when in the early twenties I was starting life as a research biochemist, I was greatly attracted to the biochemistry of mental disease. I followed the lectures for the Diploma in Psychological Medicine, and worked at the Fulbourn Mental Hospital near Cambridge on the creatinine metabolism in catatonic patients suffering from what we used to call in those days dementia praecox. I published one paper (with T. J. McCarthy), but my hopes soon faded, and when I read an excellent review on the subject which covered much literature, and ended by saying that biochemists had grown tired of 'fishing in distilled water for the causes of mental disease,' I realised that I had better find something more worthwhile. Eggs and embryos were the answer, and very worthwhile they were. 256 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Not long ago, a colleague chided me for using the term 'the biological revolution. ' Like many others, I have employed it as an umbrella term to refer to the seemingly vast, rapidly-moving, and fre quently bewildering developments of contemporary biomedicine: psy chosurgery, genetic counseling and engineering, artificial heart-lung machines, organ transplants-and on and on. The real 'biological revo lution,' he pointed out, began back in the nineteenth century in Europe. For it was then that death rates and infant mortality began to decline, the germ theory of disease was firmly established, Darwin took his famous trip on the Beagle, and Gregor Mendel stumbled on to some fundamental principles of heredity. My friend, I think, was both right and wrong. The biological revolution did have its roots in the nineteenth century; that is when it first began to unfold. Yet, like many intellectual and scientific upheav als, its force was not felt for decades. Indeed, it seems fair to say that it was not until after the Second World War that the full force of the earlier discoveries in biology and medicine began to have a major impact, an impact that was all the more heightened by the rapid bi omedical developments after the war. 336 pp. Englisch.…

You will find out more about the roles that others play in the grant-spending process; thus you will have an advantage in dealing with others. You will receive tips for spending grant dollars effectively and will be alerted to obstacles that may prevent you from maximizing grant funds. 'Grants programs should be run more efficiently, cut out the organizational 'fat,' and develop better management techniques,' a trustee of the Rosenberg Foundation was quoted as saying in the Foundation News recently. In this same issue, a leader of the Alcoholism Center for Women in Los Angeles told of trim ming superfluous grant spending across the board. 'We want to provide the same services,' she stated. 'We're cutting the fat. ' The topic of the article was Cali fornia's Proposition 13 and its impact on nonprofit organizations that depend on grant funds for their survival.

This item is printed on demand - it takes 3-4 days longer - Neuware -Cell biology is moving at breakneck speed, and many of the results from studies on insects have helped in understanding some of the central problems of biology. The time is therefore ripe to provide the scientific community with a series of up-to-date, well illustrated reviews of selected aspects of the sub microscopic cytology of insects. The topics we have included fall into four general groups: seven chapters deal with gametogenesis, four concern develop ing somatic cells, seventeen chapters describe specialized tissues and organs, and three chapters cover cells in pathological states. These accounts are illustrated with over 600 electron micrographs. The more than 1100 pages in the two volumes of Insect Ultrastructure combined labors of 49 dedicated contributors from II countries. represent the These authors have digested and critically summarized a very large body of information, and some measure of this effort can be gained from consulting the bibliographies that close each of the 31 chapters. These contain 2400 publica tions authored by 1500 different scientists. However, before we congratulate ourselves on the advanced state of our knowledge, it is worth remembering that representatives of less than 0.01 % of the known species of insects have been examined with the electron microscope. 652 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The structural features responsible for the immunogenicity of certain parts of native protein molecules have been of interest to immunochemists and protein chemists for over three decades. Following the early work of Landsteiner in 1942, which showed that peptide fragments from silk fibroin exhibited an inhibitory activity toward the reaction of the protein with its antibodies, fragments from many other protein systems have been isolated and studied. However, no concerted effort was (or could be) devoted to the elucidation of the complete antigenic structure of a protein. In order for these endeavors to be successful and meaningful, knowledge of both the amino acid sequence and the detailed three-dimensional structure of the protein are necessary. Such information was not available for a protein until early in the 1960s. This and the fact that protein chemistry was not in fact sufficiently developed early in the 1 960s to enable the success ful completion of the entire antigenic structure of a protein were major contributing factors for the slow progress in this field. Determination of the antigenic structures of proteins, therefore, posed a chemical challenge of enormous proportions. For these reasons, many investigators diverted their attention to study the immunochemistry of homo- or mixed amino acid polymers in the hope that the information derived from these systems may prove useful in the understanding of the immunochemistry of proteins. A great many data on these systems were accumulated that have proved valuable in gaining some information on the immune mechanism. 464 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Physical illness cannot be effectively treated other than in the context of the psychological factors with which it is associated. The body may have the disease, but it is the patient who is ill. Research psychologists from a number of different backgrounds have, in the past few decades, turned increasingly to the study of physical illness, and there is now an extensive literature on preventive behaviors, the role of stress in the etiology of illness, the patient's reactions to illness and its treatment, and the physician-patient relationship. At the same time practicing clinical psychologists have extended their concern beyond the treatment of speci fically psychiatric disorders, to include also the psychological care of people experiencing distress through illness or injury. Traditionally, these patients have tended to fall through the net, unless their distress is so great that it assumes the proportion of a psychiatric disorder that can then be treated in its own right. Because the physical disorder is the primary one, its existence has detracted from the salience of the very real emotional disturbance to which it can give rise. Moreover, emotional reactions in this setting, being the norm, seems to have been regarded as not meriting special attention and care. This situation is chang ing, and it is not just psychologists or psychiatrists who are responsible for the shift in attitudes. Within general medicine itself, there is now a renewed empha sis on the care of the whole patient and not just the disease. 144 pp. Englisch. …

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The appreciable evolution of the nearly teenaged branch of atomic and molecular physics called beam foil spectroscopy is clearly depicted in the present volumes, which are devoted to publication of presentations at the Fourth International Conference on Beam Foil Spectroscopy and Heavy Ion Atomic Physics Symposium. The transition from childhood to adolescence parallels human experience in that diffusion of interests and interactions beyond the confines of the original family has most certainly occurred. The pre-occupation with techniques and their develop ment has been largely replaced by interest in the physics of the widest possible array of atomic and molecular physics experiments, in which spectroscopic study (visible, UV, XUV, X-ray, electron) of collisional interactions of fast beams is the unifying theme. The description 'accelerator-based atomic physics' is perhaps more representative of the subject today than is the original, beam-foil spectroscopy,' since so many experiments have nothing to do with foils, and furthermore, employ spectroscopy mainly as an incidental tool. What, then distinguishes beam-foil spectro scopy from overlapping fields of atomic collisions physics In an era where the boundaries are becoming ever more diffuse, there can be no clear definition. A good functional definition was recently conceived by Peter Erman, under the salubrious stimulus of a large Tennessee bourbon: it is the tribal experience of the community of scientists who have banded together to develop the discipline over the past dozen years, as shared at the triennial conferences devoted to it. 488 pp. Englisch.…

A total of 77 lecturers and students with diverse backgrounds in Chemistry, Physics, Mathematics and various interdisciplinary subjects attended the ASI. In the proposal submitted to NATO for financial support for this ASI, it was suggested that recent impressive experimental developments coupled with the availability of sophisticated computer technology for detailed investigation of the relativistic structure of atoms, molecules and solids would provide an excellent testing ground for the validity and accuracy of the theoretical treatment of the rela tivistic many-electron systems involving medium and heavy atoms. Such systems are also of interest to the current energy crisis because of their usage for photovoltaic devices, nuclear fuels (UF6), fusion lasers (Xe\*2)' catalysts for solar energy conversion, etc. 556 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Trauma to the abdomen, both accidental and willful, has become increasingly common in this era of increasing violence. Large numbers of patients all over the country are admitted to emergency rooms because of abdominal trauma of varying degrees of severity. All too often the correct diagnosis is suspected belatedly or not at all, so that proper treatment is not initiated in sufficient time to be lifesaving. Not infre quently, the injured patient is examined by an intern or an insufficiently experienced resident physician. Even in instances where more senior internists and surgeons are available, detailed knowledge about the necessary methodology to establish the correct diagnosis and institute the appropriate treatment is lacking. This monograph, representing the felicitous collaboration of a surgeon and a radiolo gist together with several other contributors, is timely and important. The authors (and their contributors) have approached their subject with a wealth of clinical experi ence obtained in several very active acute-care municipal hospitals in the largest city in this country. They have observed and treated a very large number of patients with a multitude of traumatic causes, including firearm injuries, stab wounds, vehicular accidents, falls, and assaults. The authors have divided this work into four main sections: General Perspectives on Abdominal Injury, Types of Abdominal Injuries, Specific Diagnostic Techniques, and Specific Organ or Supporting-Structure Injury. 244 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -The roles of both the consumer and the health advocate professional have become increasingly significant in to day's climate of 'rationed' health care. It seems clear that the timely exchange of ideas among seasoned health care advocates is necessary if we are to deal with the complex problems of a technologically advanced so ciety seeking to ration its heath care in a truly humane way. Toward such a timely exchange, the first Confer ence on Advocacy in Health Care was organized by the Health Advocacy Program of Sarah Lawrence College and recently held. Advocacy in Health Care: The Power of a Silent Constituency is the proceedings of the conference and will, we believe, greatly extend our efforts to share both the problems and solutions that effective patient advocacy entails. Never before has the issue of advocating for special population groups by combining the resources of consumers and professionals been the exclusive focus of one volume. This book discusses the power of such an alignment and describes specific organizational techniques that have been effective in bringing about changes in the delivery system. The final section of the book, 'Questions, Com ments and Answers,' presents a selection of topics of special interest that surfaced during the open disc- vii viii Preface sion at the last conference session. The comments were forthright in their criticism of public policy, and the vigor of the argument underscored the vitality of the co alition between professionals and consumers. 164 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -This book brings together the personal accounts and reflections of nineteen mathematical model-builders, whose specialty is probabilistic modelling. The reader may well wonder why, apart from personal interest, one should commission and edit such a collection of articles. There are, of course, many reasons, but perhaps the three most relevant are: (i) a philosophicaJ interest in conceptual models; this is an interest shared by everyone who has ever puzzled over the relationship between thought and reality; (ii) a conviction, not unsupported by empirical evidence, that probabilistic modelling has an important contribution to make to scientific research; and finally (iii) a curiosity, historical in its nature, about the complex interplay between personal events and the development of a field of mathematical research, namely applied probability. Let me discuss each of these in turn. Philosophical Abstraction, the formation of concepts, and the construction of conceptual models present us with complex philosophical problems which date back to Democritus, Plato and Aristotle. We have all, at one time or another, wondered just how we think; are our thoughts, concepts and models of reality approxim&tions to the truth, or are they simply functional constructs helping us to master our environment Nowhere are these problems more apparent than in mathematical model ling, where idealized concepts and constructions replace the imperfect realities for which they stand. 332 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -In the years since the initial discovery that blood from diabetic patients contains increased amounts of a posttranslationally gluco sylated form of hemoglobin (hemoglobin Ale)' an impressive number of studies have clarified and expanded the use of glycohemoglobin levels to assess disease status. Many other structural proteins have been shown to undergo similar changes, including proteins from tissues most commonly affected in diabetes (e.g., lens, aorta, peripheral nerve, basement membrane). Thus, the nonenzymatic glycosylation of hemoglobin emerges as an invaluable model for the pathogenesis of certain chronic diabetes complications. In addition to reviewing a wealth of investigative possibilities in the area of these chronic complications-including eye, kidney, nerve, and vascular disease-Dr. Cohen indicates how enhanced nonenzymatic glycosylation in uncontrolled diabetes underscores the pressing need for maintenance of long-term euglycemia. Dr. Cohen is an endocrinologist and diabetes specialist whose research activities have largely focused on the chemistry and metabo lism of the basement membrane in diabetes. This superb monograph on nonenzymatic glycosylation clearly shows the major trends of her past and present research and clinical activities. This book is beautifully written and a pleasure to read. It provides great insight into the mechanisms of the pathogenesis of the oom- vii viii Foreword cations of diabetes and should be of immense value not only to basic and clinical investigators, but also to internists, diabetologists, and endocrinologists in clinical practice. 156 pp. Englisch.…

This Institute was the second course of the International School of Low Temperature Physics which was established at the Centre in 1977, with the guidance and inspiration of T. Regge and A. Zichichi. The 1979 course selected a topic on one of the most rapidly advancing fields of condensed matter physics in the late 70's. The program of topics and speakers was developed with the advice of the Organizing Committee, composed of J. Friedel, N. D. Mermin, R. E. Peierls, T. Regge and J. Wheatley. These two weeks were memorable for the range and depth of the lectures and seminars, and the sustained high interest of the students and faculty through a damanding schedule of over 5 hours a day of formal sessions. A large fraction of the leading researchers in the field were there. It would have been impossible to gather such a large group five years earlier, for the field itself is hardly 10 years old. Although the foundations of the thermodynamics of surface films were laid down by Gibbs about 100 years ago, and experiments on oil/water monolayers were carried out by Pockels and Rayleigh at about the same time, the beginnings of the modern field were much more recent. 380 pp. Englisch.…
