Taschenbuch. Condición: Neu. Neuware -This book is about compressing data to make digital systems work more effi ciently. According to the dictionary, when something is compressed, it is con densed, squeezed, constricted, or pressed together to fit into less space. Air is compressed for a variety of useful purposes. Businesses are downsized to make them more efficient. We pack our daily schedules tighter and tighter to accomplish more. Who has not crushed an empty soda can for recycling Many different things can be compressed, including the data in computers, communications links, consumer-electronics gear, and all sizes and shapes of digital systems. Are you curious about how data compression squeezes the 'air' out of digital bits Would you like to know where it is used and, increasingly, why the marketplace demands it be used Would you like to learn the right way to build data compres sion into your products Then, this book is for you. This exciting technology and its importance for current and future digital systems are explained in easy to understand terms. No previous knowledge of data compression is required because the necessary technical background is carefully developed. Neither is an extensive understanding of mathematics be cause there are few equations and important ideas are graphically illustrated. If you read any of the popular or professional monthly magazines that cover the latest advances in digital systems, your background is adequate. If you understand this preface, you are ready to tackle this book.

Taschenbuch. Condición: Neu. Neuware -since the earliest results on the linkage between ras activation and cell transformation appeared a vast amount of additional information has been generated which emphasizes the importance of ras-related genes in membrane trafficking, cell proliferation, differentiation and cancer. These advances led to the development of new strategies for the diagnosis, prognosis and prevention of cancer. Ras-related genes appear to be central to the mechanism of transformation by other oncogenes and therefore constitute a focal point upon which attempts to intervene in the process of carcinogenesis will be concentrated. The present volume contains the contributions to the NATO Advanced Research Workshop on the 'The Superfamily of ras-Related Genes' held in Agia Pelagia, Heraklion, Crete, Greece, May 1991. At this meeting the leading researchers in this field carne together to discuss the most recent progress in analysis of biological function of the ras-related genes. As an organizer I feel that the Workshop was a success, and would like to thank all the participants and the contributors to this volume. I thank the NATO Scientific Affairs Division, Brussels, the Greek Ministry of Industry, Energy and Technology, the International Center for Cancer Research, the National Hellenic Research Foundation and the Medical School, University of Crete for sponsoring the Meeting.

Taschenbuch. Condición: Neu. Neuware -Flavour is an important sensory aspect of the overall acceptability of meat products. Whether we accept or reject a food depends primarily on its flavour. Both desirable and undesirable flavour effects are contemplated. Furthermore, threshold values of different flavour-active compounds have an important effect on the cumulative sensory properties of all foods. Meat from different species constitutes a major source of protein for most people. Although raw meat has little flavour and only a blood-like taste, it is a rich reservoir of non-volatile compounds with taste-tactile properties as well as flavour enhancers and aroma precursors. Non-vola tile water-soluble precursors and lipids influence the flavour of meat from different species. In addition, mode of heat processing and the nature of additives used may have a profound effect on the flavour of prepared meats. This book reports the latest advancements in meat flavour research. Following a brief overview, chapters 2 to 5 discuss flavours from different species of meat, namely beef, pork, poultry and mutton. In chapters 6 to 12 the role of meat constituents and processing on flavour are described. The final section of the book (chapters 13 to 15) summarizes analytical methodologies for assessing the flavour quality of meats. I wish to thank all the authors for their cooperative efforts and com mendable contributions which have made this publication possible.

Taschenbuch. Condición: Neu. Neuware - The need for writing a monograph on polymer blends and composites became apparent during presentation of material on this subject to our advanced polymers class. Although the flood of important research in this area in the past decade has resulted in many symposia, edited collections of papers, reviews, contributions to scientific journals, and patents, apparently no organized presentation in book form has been forthcoming. In a closely connected way, another strong impetus for writing this monograph arose out of our research programs in the Materials Research Center at Lehigh University. As part of this effort, we had naturally compiled hundreds of references and become acquainted with many leaders in the field of blend and composite research. Perhaps the most important concept stressed over and over again is that engineering materials are useful because of their complexity, not in spite of it. Blends and composites are toughened because many modes of resistance to failure are available. Although such multimechanism processes are diffi cult to describe with a unified theory. we have presented available develop ments in juxtaposition with the experimental portions. The arguments somewhat resemble the classical discussion of resonance in organic chemistry, where molecular structures increase in stability as more electronic configura tions become available.

Taschenbuch. Condición: Neu. Neuware - Judging from the articles published in Biochemistry, magnetic resonance techniques (NMR and ESR) are now among the most popular methods in biochemical research. The series Biological Magnetic Resonance, the fifth volume of which we are proudly presenting, is intended to provide authori tative coverage of topics of current interest. Previous volumes have covered a number of aspects in a thorough and pedagogical fashion rarely found in other publications in this field. Continuing to fulfill the mission of the series, this volume presents a chapter by Baxter, Mackenzie, and Scott on the applications of carbon-13 NMR spectroscopy in investigations of methabolic pathways in vivo. Blom berg and Ruterjans give a comprehensive summary of the use of nitrogen-15 NMR in studies of systems of biological interest. Phosphorus-3I NMR investigations of enzyme systems are described by Rao. Tsai and Bruzik outline the principles of and summarize the state-of-the-art advances in the 18 use of oxygen isotopes e 70 and 0) in phosphorus-3I and oxygen-17 NMR studies of biophosphates. Lipid-protein interactions as reflected in ESR and NMR data are discussed by Devaux. We wish to thank the authors for their cooperation in maintaining the and continued high standards of the series.

Taschenbuch. Condición: Neu. Neuware - Teratology is at once among the oldest and youngest of human preoccupations. Coincident with man's first observations of the stars were his recordings of human and animal deformities. But, such aberrancies must have occurred even earlier, for although it is one of those things-like evolution-that cannot be proven, it is nevertheless indisputable that dysmorphogenesis must have occurred from the time complex forms of life first arose on our planet; and that from the beginnings of human awareness our species was conscious of such happenings. From the earliest recordings of this fascination with the form and meaning of abnormality a tortuous but continuous line extends to modern struggles to understand and control these manifestations. And now, after long occupying an honorable but peripheral place in the halls of philosophical and scientific pursuits, teratology has quite suddenly come to take a prominent position at the hub of a complex crossroads of human concerns. This shift in its fortune has taken several forms. Fetal maldevelopment has become the concern of environmentalists, activists of various persuasions, indus trial organizations, government agencies, ethicists, parents-i. e. , individuals and groups whose actions are impelled by apprehension. Such motives are of course not without basis; the trauma of thalidomide left a scar yet raw. For still others clinicians, academics, experimentalists-the upsurge in the interest in fetal mal development is at a different level, and their pursuits are broad, taking external agents as but one of the causes of defective development.

Taschenbuch. Condición: Neu. Neuware - The American Institute for Cancer Research (AICR) sponsored its second annual conference on nutrition and cancer. The theme was 'Exercise, Calories, Fat, and Cancer' and the conference was held September 4-5, 1991 at the Ritz Carlton Hotel in Pentagon City, Virginia. This proceedings volume contains chapters from the platform presentations and abstracts from each poster presentation. Relationships among physical activity, calorie consumption, energy expenditure, dietary fat, and cancer are described in the context of epidemiologic, animal, and in vitro studies. Dietary recommendations to lower cancer risk are based on expanding evidence relating nutrition and cancer. Identification of the precise dietary contribution to disease is complicated by the concurrent genetic and environmental contributions, in addition to the inherent difficulties in gathering and interpreting epidemiologic data. Individual variations in cancer risk are the result of differences in genetic and environmental factors including sources and amounts of calories consumed, metabolism, and energy expenditure. Human and animal studies describing independent and combined influences of exercise, calorie restriction, and dietary fat on carcinogenesis are reported in this volume.

Taschenbuch. Condición: Neu. Neuware - Fifteen volumes and one supplement have now appeared in the series known as Evolutionary Biology. The editors continue to seek critical reviews, original papers, and commentaries on controversial topics. It is our aim to publish papers primarily of greater length and depth than those normally published by society journals and quarterlies. The editors make every attempt to solicit manuscripts on an international scale and to see that no facet of evolutionary biology-classical or modern-is slighted. Manuscripts should be sent to anyone of the following: Max K. Hecht, Department of Biology, Queens College of the City University of New York, Flushing, New York 11367; Bruce Wallace, Department of Biology, Virginia Polytechnic Institute and State University, Blacksburg, Virginia 24061; Ghillean T.

Taschenbuch. Condición: Neu. Neuware - Masters Theses in the Pure and Applied Sciences was first conceived, published, SIld disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) \* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna and broader dissemination. tional publishing house to assure improved service Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 30 (thesis year 1985) a total of 12,400 theses titles from 26 Canadian and 186 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work.

Taschenbuch. Condición: Neu. Neuware - To meet the needs of an ever-growing world population for food and fiber, agriculture uses an arsenal of chemicals to control insects, weeds and other pests that compete with man in the agricultural arena. In addition to their intended effect, many of these biologically active materials affect non-target organisms including man himself. There is concern about the resulting occupational exposure of those who work in agriculture and the environmental health of those who live in rural areas. Unintended side effects from the use of agricultural chemicals are further complicated by the dispersal of these substances well beyond the area of immediate use, through food chains, atmospheric transport, irrigation runoff, percolation to and diffusion through ground water, sometimes giving rise to public health and environmental problems at a distance from the place of application. In addition to toxic substances introduced into the agro ecosystem by man, one must be concerned about naturally occurring agents including mfcotoxins, plant poisons, infective biological agents and the levels of certain heavy metals. The formation of toxic substances, many of them mutagenic, during cooking and other processing of food is a related problem. While acute effects are more immediate and somewhat readily discerned, chronic and genetic effects tend to be more obscure and sometimes surface in a crisis situation long after substantial damage has been sustained. Genotoxicity assays and epidemiological studies play increasing roles in predicting and evaluating long term effects of low-level exposure to toxic materials.

Taschenbuch. Condición: Neu. Neuware - The recent surge of interest in recombinant DNA research is understandable considering that biologists from all disciplines, using recently developed mo lecular techniques, can now study with great precision the structure and regulation of specific genes. As a discipline, molecular biology is no longer a mere subspeciality of biology or biochemistry: it is the new biology. Current approaches to the outstanding problems in virtually all the traditional disci plines in biology are now being explored using the recombinant DNA tech nology. In this atmosphere of rapid progress, the role of information exchange and swift publication becomes quite crucial. Consequently, there has been an equally rapid proliferation of symposia volumes and review articles, apart from the explosion in popular science magazines and news media, which are always ready to simplify and sensationalize the implications of recent dis coveries, often before the scientific community has had the opportunity to fully scrutinize the developments. Since many of the recent findings in this field have practical implications, quite often the symposia in molecular biology are sponsored by private industry and are of specialized interest and in any case quite expensive for students to participate in. Given that George Wash ington University is a teaching institution, our aim in sponsoring these Annual Spring Symposia is to provide, at cost, a forum for students and experts to discuss the latest developments in selected areas of great significance in biology. Additionally, since the University is located in Washington, D. C.

Taschenbuch. Condición: Neu. Neuware - Cooperating Heterogeneous Systems provides an in-depth introduction to the issues and techniques surrounding the integration and control of diverse and independent software components. Organizations increasingly rely upon diverse computer systems to perform a variety of knowledge-based tasks. This presents technical issues of interoperability and integration, as well as philosophical issues of how cooperation and interaction between computational entities is to be realized. Cooperating systems are systems that work together towards a common end. The concepts of cooperation must be realized in technically sound system architectures, having a uniform meta-layer between knowledge sources and the rest of the system. The layer consists of a family of interpreters, one for each knowledge source, and meta-knowledge. A system architecture to integrate and control diverse knowledge sources is presented. The architecture is based on the meta-level properties of the logic programming language Prolog. An implementation of the architecture is described, a Framework for Logic Programming Systems with Distributed Execution (FLiPSiDE). Knowledge-based systems play an important role in any up-to-date arsenal of decision support tools. The tremendous growth of computer communications infrastructure has made distributed computing a viable option, and often a necessity in geographically distributed organizations. It has become clear that to take knowledge-based systems to their next useful level, it is necessary to get independent knowledge-based systems to work together, much as we put together ad hoc work groups in our organizations to tackle complex problems. The book is for scientists and software engineers who have experience in knowledge-based systems and/or logic programming and seek a hands-on introduction to cooperating systems. Researchers investigating autonomous agents, distributed computation, and cooperating systems will find fresh ideas and new perspectives on well-established approaches to control, organization, and cooperation.

Neuware - Progress made in the last 20 years clearly indicates that the cell surface is an extremely dynamic structure involved in fundamental processes such as cell motility, innervation, and cell adhesion. Of particular interest is the finding that, in several tissues, the cell surface is differen tiated at the intercellular region, thereby providing communicating chan nels between apposing cells. Although our actual knowledge of the precise structures and mecha in the complex process of intercellular communication is still nisms involved scanty, evidence has been presented that ions and molecules diffuse from cell to cell, establishing a physiological continuum. Embryonic differentia tion, cell growth, neoplasia, electrical synchronization in nerve and mus cles, as well as immune response seem to be related to ceIl communication. In organizing this volume, it has been our intention to provide the reader with an actual review of the processes involved in intercellular communication in normal tissues as well as in neoplasia. We sincerely believe that the opinions and experiences described herein will be of help in establishing new perspectives for the future of this exciting new field of cell biology. We wish to thank all the colleagues who joined us in the organization of this volume, as well as Plenum Publishing Corporation for making its appearance possible.

Taschenbuch. Condición: Neu. Neuware - The authors of the papers presented in this volume are either members of the International Study Group on Special Educational Needs or their representatives. This is a small seminar, convened by invitation, involving participants from the United Kingdom, North America, Europe and New Zealand. The membership is multi-discip linary and all the participants have a professional interest in some 'aspect of special educational needs. Several historical patterns played a part in the development of the seminar, one being the evolution in England and Wales of special education legislation growing out of the Warnock Committee Report. This legislation, in turn, has been influenced by the special education developments in the United States which led to the passage of 'The Education of All Handicapped Children Act,' Public Law 94-142, in 1975. A second theme, leading to the development of the seminar, was the growing interest internation ally in learning disabilities and the establishment at the University of Southampton in England of the Learning Disabilities Unit headed by Colin Stevenson. Discussions in 1979 and 1980 held at conferences of the Association for Citizens with Learning Disabilities, the Orton Dyslexia Society meetings and elsewhere led to the proposal for a small international seminar, meeting annually, which would be concerned with research and education in the area of special educational needs. The Lord Renwick, then Chairman of the British Dyslexia Associ ation, and Colin Stevenson took the initiative in proposing that an International Conference be held at the University of Southampton.

Taschenbuch. Condición: Neu. Neuware - The tendency of fungi pathogenic for humans to have shapes in tissue distinct from their usual saprophytic morphologies has fascinated the pathologist and medical mycologist for almost a century. A primary rea son for this fascination is the possibility that fungal duality of form, or dimorphism, may be an important virulence factor that allows the zoo pathogenic fungus to survive host defenses. A second reason relates to the desire to gain basic insights into the regulation of cellular develop ment and morphogenesis among the etiological agents of human mycoses. Many excellent treatises have appeared within the recent past dealing with fungal dimorphism. However, it is becoming increasingly clear that it may be beyond the capability of one or a few authors to review this subject adequately. Instead, the ever-increasing volume ofliterature asso ciated with fungal dimorphism and the diversity offungi now recognized to exhibit a type of dimorphism suggest that a volume comprised of con tributions by numerous researchers may be more appropriate. This per ception provided me with the motivation to compile a multiauthor volume.

Neuware - This book is the proceedings of two symposia, on Proteins of the Nervous System and Myelin Proteins, held as part of the Third Meeting of the International Society of Neurochemistry in Budapest, July 1971. If confirmation of the utility for such a book was needed, it was obtained with the independent publication of a review on Proteins of the Nervous System (1) covering essentially the same ground. This review is an excellent collection of the earlier litera ture. The present volume summarizes the more recent advances in this field, and in addition covers those areas, glycoproteins and peptide hydrolases, which were not dealt with by Shooter and Einstein (1).

Taschenbuch. Condición: Neu. Neuware - The cultural-test-bias hypothesis is one of the most important scien tific questions facing psychology today. Briefly, the cultural-test-bias hypothesis contends that all observed group differences in mental test scores are due to a built-in cultural bias of the tests themselves; that is, group score differences are an artifact of current psychomet ric methodology. If the cultural-test-bias hypothesis is ultimately shown to be correct, then the 100 years or so of psychological research on human differences (or differential psychology, the sci entific discipline underlying all applied areas of human psychology including clinical, counseling, school, and industrial psychology) must be reexamined and perhaps dismissed as confounded, contam inated, or otherwise artifactual. In order to continue its existence as a scientific discipline, psychology must confront the cultural-test-bias hypothesis from the solid foundations of data and theory and must not allow the resolution of this issue to occur solely within (and to be determined by) the political Zeitgeist of the times or any singular work, no matter how comprehensive. In his recent volume Bias in Mental Testing (New York: Free Press, 1980), Arthur Jensen provided a thorough review of most of the empirical research relevant to the evaluation of cultural bias in psychological and educational tests that was available at the time that his book was prepared. Nevertheless, Jensen presented only one per spective on those issues in a volume intended not only for the sci entific community but for intelligent laypeople as well.

Taschenbuch. Condición: Neu. Neuware - One day, in a moment of weakness, I fell prey to the temptation to organize and edit this volume on the mechanism of insulin action. The major reason for attempting to resist, of course, is the amazing speed at which advances are being made in this field. The usefulness of books such as this is often quickly compromised by new findings obtained during and just after publication. Happily for the contributors to this volume and myself, this unfortunate fate does not appear to be in store for us. New and important findings will undoubtedly continue to flow in this field during the next few years, but I believe this will increase rather than decrease the usefulness of this volume. As a matter of fact, as we go to press, I am delighted both that I was tempted and that I failed to resist. There are two basic reasons for my enthusiasm about this book, and they both relate to this issue of timeliness. First, each of the contributors has had an opportunity to update the scientific content of the various chapters only a few months before actual publication of this volume. The material presented in this volume is, at publication, contemporary with the current original literature. This volume thus provides an ex cellent framework for assessing new discoveries in this field for some time to come.

Taschenbuch. Condición: Neu. Neuware - This volume collects most of the papers presented at the International Workshop on Robustness in Identification and Control, held in Torino (Italy) in 1988. The main focal point of the workshop was Unknown But Bounded uncertainty and associated robustness issues in identification and control. Recent years have seen a growing interest in studying models which include un known but bounded uncertainty. The motivation for dealing with such models is derived from robustness considerations. In many applications, some performance specification must be met for all admissible variations of the uncertain parameters. A second motivation for models with this type of uncertainty stems from the fact that the statistical description of uncertain variables may not be well known or even not suitable. For example, in some cases, only a small number of measurements is available and the resulting errors are due to analog-digital conversion, modelling ap proximation or round-off, so that a statistical description may actually be unreliable. The interest in unknown but bounded setting is certainly not new. In fact, en gineering practice demands for appropriate algorithms in dealing with finite sample properties, finite parameter variations, tolerance analysis, etc. Despite the natural need for such methods, the lack of sufficiently well assessed theoretical results and algorithms prevented a systematic use of these procedures until recent years. How ever, in the last few years, important advances have been made both in estimation theory and in stability analysis.

Taschenbuch. Condición: Neu. Neuware - In the l~nited States and in Europe~ there has been an increasing interest in the relationship between individual behavior and disease. The American National Academy of Sciences (Hamberg, Elliott, and Parron, 1982)' through its Institutes of Medicine, has estimated that as many as 50 percent of chronic disease cases can be traced to individual behaviors such as smoking, diet, exercise, etc. Similar conclusions have been reached by a variety of European investigators and institutes. The World Health Organization has also expressed considerable interest in individual behavior in relation to the development of chronic disease. Thus, throughout the NATO countries there has been increased awareness of the relationship between behavior and disease. However, communication among investigators in different countries has been rather limited. Further, many different scientific disciplines including psychology, sociology, medicine, microbiology, statistics, and epidemiology have all developed new and different literatures in this field. One purpose of this book is to bring together contributions from scientists in each of these fields. Much of the variance in individual health behavior occurs across countries rather than within countries. Thus, we can learn much from comparing behavior-disease relationships across countries. To date, there have been few studies which have had an adequate international basis for these comparisons. Interest in behavioral epidemiology is a relatively recent phenomena. Thus, many scientists are entering the field without uniform background, experience, or training. This book discusses approaches common in a variety of NATO countries.

Taschenbuch. Condición: Neu. Neuware - This volume describes the proceedings of the Workshop Conference on The Human Testis which was held at Positano, Italy, April 23-25, 1970. The format of the book has been arranged according to topics discussed during the Conference. Each chapter includes individual contributions followed by discussion. Thus, this volume provides a current critical evaluation of the subjects discussed. The Editors assume responsibility for any shortcomings and wish to thank all par~ ticipants for their unprecedented cooperation in making this publi cation possible. The Editors are indebted to Miss Barbara Martin for her able secretarial and administrative assistance and to Mrs. Griff T. Ross who supervised the secretarial staff during the conference. Rec ognition is also due to Mrs. M. Flack for editorial assistance. The Workshop Conference could not have taken place but for the Serono Foundation, which supported this Meeting as well as the pub lication of the Proceedings of this Workshop. The physical as well as the technical arrangements were under the careful direction of Mr. Cesare Florimonte of the Serono Foundation. The support pro vided by the Serono Foundation is another proof of its generosity in stimulating scientific exchanges and a demonstration of its con tinuous efforts to support basic and applied studies in the field of human reproduction. We express our thanks to our Publisher, Plenum Press, for their fine cooperation and for ensuring the rapid publication of this vol ume.

Taschenbuch. Condición: Neu. Neuware - The second half of the twentieth century has witnessed remarkable advances in technology. The unquestioned leader in this race has been computer technology. Even the most modest personal computers today have computing power that would have astounded the leading technol ogists a few decades earlier, and what's more, similar advances are pre dicted for many years to come. Looking towards the future, it has been conservatively estimated that in 2047 computers could easily be 100,000 times more powerful than they were in 1997 (Moore's law [Moore] would lead to an increase on the order of around 10 billion) [Bell]. Because of its enormous capability, computer technology is becoming pervasive across the technology spectrum. Nowadays it is not surpris ing to discover that very common household gadgets like your toaster contain computer technology. Televisions, microwave ovens, and even electric shavers contain software. And what's more, the use of computer technology has been estimated to double every two years [Gibbs]. In order to keep up with the growing technology demands and to fully utilize the ever more powerful computing platforms, software projects have become more and more ambitious. This has lead to software systems becoming dominant forces in system functionality. Further more, the ambition to realize significant portions of a system's function ality through software has extended into the high consequence realm. Presently, software controls many critical functions in (1) airplanes, (2) electronic commerce, (3) space-bound systems, (4) medical systems, and (5) various transportation systems such as automobiles and trains.

Taschenbuch. Condición: Neu. Neuware - Diabetes and cardiovascular disease together account for the largest portion of health care spending compared to all other diseases in Western society. This work seeks to provide an understanding of the causes of diabetes and its cardiovascular complications. As this understanding becomes more widely appreciated, it will serve as a foundation for evidence-based care and wider acceptance of sound science. The International Conference on Diabetes and Cardiovascular Disease, held in Winnipeg, in June 1999, was organized to bring together a multi-disciplinary group of researchers dedicated to further knowledge amongst researchers, care givers, and the managers of the health system. The invited speakers submitted their works for publication, which serves as the basis for this book. Major themes include: epidemiology of diabetes mellitus, metabolic risk factors in diabetes and cardiovascular disease, hypertension in diabetes mellitus, cardiac function in diabetes, glycemic control and improved cardiovascular function, diabetes management, and endothelial function in diabetes.

Taschenbuch. Condición: Neu. Neuware - Interventional cardiology is a creative, innovative, and rapidly advancing frontier of cardiology. There has been mind-boggling proliferation of tech nology in this field, the use of which requires extraordinary skills and know how. In order to keep pace with the innovative genius of interventional cardiologists, it is indeed desirable to have specialty issues updating us on technology-orientated therapeutic procedures. Contemporary interventional cardiology care is a highly specialized art, dependent on critical decision making, selection of the most appropriate inter ventional procedure, and the operator possessing extraordinary skills and compassion. This first volume of the new series, Supported Complex and High Risk Cor onary Angioplasty, attests to the preceding statement. Dr. Fayaz Shawl has mastered the procedure and has been very thoughtful and innovative in the clinical application of the percutaneous cardiopulmonary bypass support tech nique. This book provides to an interventionist the basic principles of car diopulmonary bypass, identification of the high risk coronary angioplasty patient, and other alternate support devices for myocardial protection. Dr. Shawl and his team of talented contributors are to be complimented for providing us with this impressive volume on high technology. There will be ongoing specialty issues in this series highlighting the devel opments, complications, and advances in interventional cardiology.
