Taschenbuch. Condición: Neu. Neuware -Following the development of gray-scale imaging, real-time scanning, Doppler examination, and high-frequency sonography, endosonography is one of the latest major breakthroughs in the history of diagnostic ultrasound. Although early attempts at inserting ultrasound transducers in natural cavities of the body can be traced back more than two decades, only in the past few years has technology allowed the development and commercialization of effective, easy-to-use endosono scopic probes. Because the transducer can be placed in direct contact with or close to lesions, high frequencies (up to ~2 MHz) can be used, yielding cross-sectional images of unsurpassed resolution. The availability of specially designed intracorporeal probes for specific natural cavities that are routinely explored by conventional (optical) endoscopy or palpation has significantly expanded the diagnostic applications of sonography. Transrectal and transvaginal examinations are now performed routinely in many institutions, and virtually all sonographic equipment manufac turers have in their line of products at least one endorectal and one endovaginal transducer. Most endosonoscopic probes connect to existing scanners, and for radiology departments, the invest ment for transrectal or transvaginal scanning will usually be limited to the purchase of the specific probe. In this book, clinical applications of endosonography (excluding transesophageal echocardio graphy) are covered by European and North American experts. Current equipment and techniques of examination are described in detail to help newcomers get started in the field of endosonography. 200 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -The thirty-five chapters in this book are edited versions of papers presented at the Advanced Research Workshop, State Intervention on Behalf of Children and Youth, which took place in Maratea, Italy, February 20-24, 1989. The Workshop was attended by leading child welfare researchers from most of the Western countries. Represented were scholars and practitioners from disciplines as diverse as law, social work, neurology, economics, political science, education, psychology, and psychiatry. This variety of disciplines considerably enriched the discussions at the Workshop and is reflected in a set of interesting and, we believe, potentially useful research papers. This book is divided into four sections, each dealing with dominant themes of state intervention. The first section deals with research on organizing for state intervention and related ways of providing accountability. The second section deals with research on young persons in conflict with the law, the third with research on child abuse and the final section with research on children in care. Many of the matters addressed in these papers relate to more than one of the topical theme headings and, therefore, might well have been located in different sections of the volume. Each section is introduced by an introductory statement that provides an overview of the papers and issues addressed, and suggests an agenda of research work to be undertaken. These introductions are based largely on workshop discussions and do not necessarily represent the views of their identified authors.

Neuware -The farming of deer as an alternative to traditional livestock enterprises is now firmly established and is expanding within several countries of the European Economic Community. However, the successful farming of deer requires the adoption of appropriate management schemes to accommodate the biological requirements of these animals. Much experience has now been gained and it is essential that this information becomes readily available througout the Community. In addition, as the volume of deer farming has increased a number of health problems have become recognised which present features distinct from other domestic ruminants. Although knowledge is still incomplete it would appear that deer may react to certain pathogens in a very different way to other domestic ruminants, presenting new problems of diagnosis and control. The rapid detection of these conditions and development of appropriate control strategies will be essential for the establishment of an economically viable deer farming industry in the Community. Much of the information on the management of farmed deer and their diseases is anecdotal and fragmented and the purpose of this meeting was to accelerate the dissemination of this knowledge between scientists in the Community committed to the development of this area of agricultural industry. The meeting, financed by the Commission of the European Communities from its budget for the Coordination of Agricultural Research in the Community was held in Scotland, on the 10th to 11th December, 1987.

Taschenbuch. Condición: Neu. Neuware -Until the early seventies, tautomeric i. e. fast and reversible rearrangement reactions accompanied by migrations of carbon-centered groups - were practi cally unknown. For a long time it was assumed that the family of tautomeric reactions was confined to proto tropic transformations only. However, the discovery in the fifties of the reversible metallotropic rearrangements showed the domain of migratory tautomerism to be substantially broader. The synthesis of the metallotropic compounds was based on the substitution of a proton in prototropic compounds by an organometallic group. This approach rarely proved fruitful when attempting to effect tautomeric rearrangements of organic and organometallic groups formed by the elements to the right of carbon in the Periodic Table. By contrast, a novel approach involving an analysis of the steric requirements inherent in the structure of the transition state of a reactive center and an examination of the stereodynamic possibilities has given rise to a target-oriented molecular design of compounds capable of rapid and reversible intramolecular migration of the type indicated. The implementation of this ap proach, which is the subject of the present book, has already led to the preparation of new tautomeric compounds in which such heavy organic migrants as acyl, aryl, sulfinyl, phosphoryl, arsinyl, and other groups migrate in molecules at a frequency 6 9 of 10 -10 S-I at ambient temperature, i. e. , at the rates comparable with protonic migrations.

This volume, as well as past and future volumes, reflects the rapid and continuing evolution of anesthesiology in the late twentieth century.

Taschenbuch. Condición: Neu. Neuware - Cereal uses range from human food and beverages to animal feeds and industrial products. It is human food and beverages which are the predominant uses covered in this book, since the nutritional quality of cereals for animal feed is described in other publications on animal nutrition, and industrial products are a relatively minor use of cereals. Cereals are the main components of human diets and are crucial to human survival. Three species, wheat, rice and maize, account for the bulk of human food. Barley is the major raw material for beer production and ranks fourth in world production. Other species such as sorghum are regionally important. This book covers all the major cereal species: wheat, rice, maize, barley, sorghum, millet, oats, rye and triticale. Specific chapters have been devoted to a description of the major end-uses of each of the species and to definition of the qualities required for each of their end uses. The functional and nutritional quality of cereals determines their suitability for specific purposes and may limit the quality of the end product, influencing greatly the commercial value of grain. An under standing of the factors that determine grain quality is thus important in the maintenance of efficient and sustainable agricultural and food production. The biochemical constituents of the grain that determine quality have been described in chapters on proteins, carbohydrates and other components. An understanding of the relationships between grain composition and quality is important in selecting grain for specific uses.

This item is printed on demand - it takes 3-4 days longer - Neuware -These volumes represent the proceedings of NATO Advanced Study Institute on the topic of 'Cognitive Processes and Spatial Orientation in Animal and Man' held at La-Baume-les-Aix, Aix-en-Provence, France, in June-July 1985. The motivation underlying this Institute stemmed from the recent advances and interest in the problems of spatial behavior. In Psychology, traditional S-R concepts were found to be unsatisfactorY for fully accounting for the complexity of spatial behavior. Coupled with the decline in such an approach, has been a resurgence of interest in cognitive types of concepts. In Ethology, investigators have begun to use more sophisticated methods for the study of homing and navigational behaviors. In the general area of Neuroscience, marked advances have been achieved in the understanding of the neural mechanisms underlying spatial behaviors. And finally, there has been a burgeoning interest and body of knowledge concerning the development of spatial behavior in humans. All of these factors combined to suggest the necessity of bringing together scientists working in these areas with the intent that such a meeting might lead to a cross-fertilization of the various areas. Possibly by providing a context in which members of the various disciplines could interact, it was felt that we might increase the likelihood of identifying those similarities and differences in the concepts and methods common to all groups. Such an identification could provide the basis for a subsequent interdisciplinary research effort. 352 pp. Englisch.

It is the 'precipitation' of up to date knowledge of amyloidosis, as presented at the International Course on Amyloidosis in Groningen, on the 10th and 11th of October 1986. Twenty years ago, Professor Mandema invited a group of scientists, who were studying the various aspects of amyloidosis from different points of view, to discuss their mutual interest in the subject. This 'First International Symposium' was held for five days in September 1967. It was a wonderful experience for the participants, as most of them had until then only read each others work in the literature. The proceedings of that symposium, which contained the 'lively' dis cussions, became a text-book for the following years. Research continued, and while the book was still in preparation, the revolutionary method of 'water-soluble amyloid' was published. In the following years, different amyloid proteins were discovered and the mo lecular basis of the different amyloid syndromes was elucidated. The increase in knowledge parallelled the availability of modern, ingenious and also rapid methods in the biomedical sciences. 400 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Rapid methodological progress is now taking place in the USSR in the solution of the problems of developing both society and economy. A considerable proportion of the total methodological problems of the USSR economy are dealt with in the present monograph. This work is intended for economists, managers and specialists in methodology, sociology and applied mathematics, and it may also be useful to researchers into operations as well as to politicians, philosophers and wide circles of readers interested in the present and future problems of the USSR economy. Readers will find here, I hope, answers to many questions. At the same time this work can be used as a manual for students and post-graduate students investigating countries with centrally planned economies. For his monograph the author has used the material originally developed for a special course of lectures called 'Macromodels of Planning'. Some sections of the book correspond to the subjects of courses on 'Mathematical Programming' and 'Operations Research' as well as to the subjects of special courses on 'Methods of Vector Optimization', 'Stochastic Programming', 'Parametric Programming' and 'Decomposition Methods of Programming', read by the author from 1971 to 1976 to the graduates and post graduates of the department of applied mathematics and management processes at Leningrad University. 492 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This compact volume is meant as a modest contribution to the ongoing debate on how to transform in particular the radically reforming Eastern European economies into more productive sociopolitical organizations. Although my main focus here is on the economics of reform and east-west assistance, I have tried to embed the multiple technical aspects of restructuring such a resource alloca tion into the context of remaking Eastern Europe. That the volume coincides with the seminal transformations of the communist countries of Eastern Europe is, of course, not fortuitous. But I shall have much less to say about the politi cal transitions from communism to parliamentary democracy, except the ways in which the latter may bolster or hinder the hoped-for economic mutations. In taking stock of where I stand on the issue of 'radical reform' of planned economics in general and the CMEA in particular, both still moving targets, I have benefited greatly from participation in formal and informal conferences on economic reform. The product has also profited from many informal discus sions and exchanges of views among friends and colleagues, including those entrusted with and purely interested in efforts on the overall topic of the study launched from within the broad context of the United Nations, my at times reluctant employer. 240 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Progress in the development of oxygen ion and mixed conductors is responsible for innovations in the fields of gas sensors, fuel cells, oxygen permeation membranes, oxygen pumps and electrolyzers. Commercialization has been impeded by materials stability and compatibility issues, high costs of fabrication and inadequate understanding of the interfacial phenomena controlling the operation of these devices. In this text we assemble a unique group of experts whose articles straddle, for the first time, all the key topical areas ranging from fundamentals relating to (a) defects, electrochemical, and interfacial processes, (b) catalysis, electrocatalysis and gas reforming, to design and fabrication including (c) advanced electroceramic processing methods, (d) materials selection and optimization, (e) and applications including scale up, commercialization and competitive technologies. This material was first presented at a NATO Advanced Study Institute held in Erice, Sicily, Italy during the period july 15-30, 1997. All the participants benefited from the integrated and synthetic approach taken to the subject matter with liberal use of examples and case studies. Many opportunities were made available for critical discussions of the key concepts and issues both within the formal sessions as well as in the cafes and restaurants which populate Erice. I join the co-organizers of the Advanced Study Institute, Professors J. Schoonman, I. Riess and M. Balkanski, in thanking NATO for providing support for the ASI.

The workshop was attended by 36 earth scientists from ten countries and 28 papers were presented. Crust/mantle recycling is one of the most fundamental processes in the Earth. The study and understanding of this process requires the consideration of the Earth as a whole system including the atmosphere, the hydrosphere and the core, as well as the crust and the mantle; effective interdisciplinary collaboration is therefore essential to our progress. The Antalya ARW gave us the opportunity to assemble key specialists from relevant branches of the earth sciences and to address our state of knowledge. This ARW proved to be very useful in attaining an interdisciplinary, mutual understanding among specialists from diverse fields such as isotope and trace element geochemistry, mineral physics, theoretical geophysics, seismology, experimental petrology, and structural geology. 300 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The purpose of this book is to describe the nature of the materno-fetal immunobiological relationship and to suggest the direction in which the management of reproduction and its failure in man is moving. The several authors, who have written about their special fields of interest, need to be read within a framework designed to blend their contributions into a whole. This preamble provides a part of that framework, by describing the early development of the embryo, that of the placenta and its membranes and their anatomical relationship with maternal tissues: in other words, the stage upon which this materno-fetal dialogue takes place. Professor Maureen Young's 'tour de force', encapsulating the whole of fetal physiology into a single chapter, completes the background information. After Maureen Young's summary of fetal physiology, Matteo Adinolfi describes the development of the immune system in the fetus, including new information that allows more accurate speculation concerning the gestational age at which fetal immune responses of various kinds may begin. Charles Loke examines the nature of antigens which are found in the placenta, concentrating on those which occur on syncytiotrophoblast and suggesting roles for them in fetal development. Arnold Klopper covers the wide range of proteins and hormones which have been studied during pregnancy and found to vary in a potentially significant way. He has been careful to distinguish between observation and hypothesis, as far as any immunomodulating action is concerned, and his analysis is a model of scientific scepticism. 244 pp. Englisch.

This workshop examined a number of relationship types with significance for information retrieval beyond the conventional topic-matching relationship. From this shared participation came the idea for an edited volume on relationships, with chapters to be solicited from researchers and practitioners throughout the world. Ultimately, one volume became two volumes. The first volume, Relationships in the Organization of Knowledge (Bean & Green, 200 I), examines the role of relationships in knowledge organization theory and practice, with emphasis given to thesaural relationships and integration across systems, languages, cultures, and disciplines. This second volume examines relationships in a broader array of contexts. The two volumes should be seen as companions, each informing the other. As with the companion volume, we are especially grateful to the authors who willingly accepted challenges of space and time to produce chapters that summarize extensive bodies of research. The value of the volume clearly resides in the quality of the individual chapters. In naming this volume The Semantics of Relationships: An Interdisciplinary Perspective, we wanted to highlight the fact that relationships are not just empty connectives. Relationships constitute important conceptual units and make significant contributions to meaning. 244 pp. Englisch.

The camera-ready paper format was chosen so that delegates could receive their copy on arrival at the Conference. The Proceedings include reviews of traditional ion exchange processes, ion chromatography and synthesis of resins. In addition there are research papers dealing with inorganic ion analysis; organic acid and organic base analysis; the theory of ion exchange and novel developments; the industrial ion exchange procedures; and finally inorganic ion exchangers. The Proceedings should therefore be of interest to those who need to be brought up to date in the various aspects of processes which involve ion exchange and ion chromatography which are now accepted as important in analysis, separation processes and process control. In each of these areas there have been important developments which are herein described. As Editors we should like to express our thanks to the individual authors for preparing their manuscripts in the required format and to Haydn Hughes for his invaluable assistance in compiling these Proceedings.

This item is printed on demand - it takes 3-4 days longer - Neuware -Historically, ruminant animals have provided farmers with the ability to utilize marginal lands for the production of high quality food for human consumption. Ruminants are able to derive their nourishment from feeds that are not in themselves capable of meeting the nutritional needs of the animal. They do this by supporting in the rumen, which is a greatly enlarged region of the stomach which precedes the animals digestive system, a microbial fermentation system. This system partially degrades complex polysaccharides and provides to the animal not only the degradation products (chiefly volatile fatty acids), but also secondary microbial metabolites and microbial biomass (most importantly microbial protein, which can be synthetized from inorganic nitrogen sources). A ruminant animal is able to survive, if not thrive, on a diet containing only cellulose, a non-protein nitrogen source such as urea, and trace minerals. The capacity of the rumen to process low quality feeds is limited by factors such as rumen volume, the time required for digestion of these feeds in the rumen, and the ability of the animal to chew the feed. Hodern ruminant animals have been intensively selected for high production potential, but the limited capacity of the rumen fermentation means that this potential cannot be realized by feeding the animal low quality feeds. The high production potential of these animals can only be realized by feeding large amounts of readily digestible, high quality feeds such as oilseed meals and grains. 332 pp. Englisch.

Despite the international spread of journals and of standard textbooks, the same practical questions constantly appear - how do you manage the psychotic patient with cerebral lupus, or the patient with intractable polymyositis, or the rheumatoid patient who has failed on almost all known therapeutic agents. Is it worth differentiating various 'overlap' syndromes How can one improve on the classification and treatment 'i}f.vasculitis Two questions - what is the patient telling us and what can we do for the patient are always central to the discussion. Although these high-minded ideals are often not fulfilled, frequently something new appears to come from individual case presentations. These cases, discussed at our weekly conferences, were contributed by a number of different staff members. Where possible, a standard format has been use in each case presentation and a comment added where indicated. A short list of relevant references has been included with each case. The aim of this book is to provide examples of these clinical problems and our own clinical approach to them - sometimes successfu~ sometimes not. 224 pp. Englisch.

There never had been a graph theoretical meeting in which infinite graphs were more than 'also rans', let alone one in which they were a central theme. In part, this is a matter of fashion, inasmuch as they are perceived as not readily lending themselves to applications, in part it is a matter of psychology stemming from the insecurity that many graph theorists feel in the face of set theory - on which infinite graph theory relies to a considerable extent. The result is that by and large, infinite graph theorists know what is happening in finite graphs but not conversely. Lack of knowledge about infinite graph theory can also be found in authoritative l sources. For example, a recent edition (1987) of a major mathematical encyclopaedia proposes to '. . . restrict [itself] to finite graphs, since only they give a typical theory'. If anything, the reverse is true, and needless to say, the graph theoretical world knows better. One may wonder, however, by how much. 276 pp. Englisch.

Among the key areas are polymer chemistry, as new binders are developed to meet increasingly stringent environmental demands; testing and evaluation, as the need to understand the factors affecting coatings performance becomes ever more intense; and studies of that enduring problem, corrosion of metal substrates, from which coatings of ever improving effectiveness are emerging. We have in this present volume of the series continued to cover aspects of these numerous developments. There are chapters on waterborne paint, a subject of increasing environmental importance, by J. W. Nicholson, and by H.-J. Streitberger and R. P. Osterloh; on a new and sophisticated test method, acoustic emission (R. D. Rawlings); and on anticorrosion coatings both organic (W. Funke) and inorganic (M. C. Andrade and A. Macias). Finally, that topic of immense practical importance to paint technology, pigmentation, is covered in a chapter by the late T. Entwistle. All the authors have brought considerable experience in their chosen field of coatings technology to the preparation of their chapters, all of which are timely reviews of developing topics. We are grateful to each author for helping in the preparation of this volume, and for putting their experience at the disposal of the wide audience for whom this book is intended. 244 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -For more than a century, heterocycles have played a crucial role in the biological and industrial development of society, becoming one of the most researched areas within organic chemistry.The first chapter of Microwave-Induced Synthesis of Aromatic Heterocycles is based on microwave theory, the latest developments in instrumentation technology, and the various microwave technologies used for synthesis. The remainder of the chapters are divided into two sections. Section A deals with the five-membered heterocycles (pyrazoles, isoxazoles, triazoles, oxadiazoles, thiazoles, imidazoles, oxazoles, oxazolines etc.) and in Section B, various six-membered heterocycles (triazines, benzoxazoles, benzimidazoles, benzothiazoles) are presented. Both sections contain a detailed, recent literature review of microwave assisted synthesis and its applicability to various aromatic heterocyclics. 104 pp. Englisch.
