Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Since the publication of the first edition of The Diabetic Pancreas in 1977, much progress has been made in various areas of diabetes research. While only a rela tively short while ago diabetes was considered a single disease, in mo…re recent years it has become apparent that it is a heterogeneous group of disorders, all of which are characterized by a decreased tolerance of carbohydrates and most of which have a genetic basis, although the genetic types vary. In more recent years, an International Work Group sponsored by the National Diabetes Data Group of the NIH proposed a now generally accepted classification, according to which the insulin-dependent ketosis-prone diabetes, formerly and inappropriately called the juvenile type, is considered a subclass of diabetes, type 1. Because it can occur at any age, it was recommended that the diagnosis based on age be eliminated. The non-insulin-dependent, non-keto sis-prone type of diabetes, which is not secondary to other diseases or conditions, and which was formerly called matu rity-onset diabetes, was considered a second subclass, type II, because although this form usually develops after age 40, it also occurs in young persons, who do not require insulin or are not ketotic. Although this classification is not entirely agreed upon by all diabetologists, for practical purposes it has been generally accepted and has been utilized by the contributors to this volume. 656 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -After the success of the previous summer schools organized by the Nuclear Physics Division of the Netherlands' Physical Society in 1975 and 1977, we thought it worthwhile to continue this tradition. The immediate very positive react…ions received from all invited speakers encouraged us to proceed with the orgaization. Although the number of students had to be restricted to about one hundred, the international character of the School was evident from about thirty nationalities which were represented. The material contained in this book covers the talks given by all speakers invited to lecture on the subject of nuclear structure research. These proceedings should therefore serve as an excellent introduction to many topics of current interest in this exciting field. We hope that the lectures and discussions as well as the many informal contacts made during the various social activities will greatly stimulate interest in nuclear structure investigations among all the participants. The organization of the summer school has been made possible by substantial support given by the Scientific Affairs Division of the North Atlantic Treaty Organization, the Netherlands' Ministry of Education and Science and the Netherlands' Physical Society. The invaluable help of the 'Bureau Congressen' of the Ministry of Education and Science and the friendly assistance of the manage ment of the College of Agriculture in Dronten contributed greatly to the pleasant atmosphere during the summer school. 444 pp. Englisch.

Recent years… have seen iITlportant advances in analytical tools and ITlethods; their applications to date will certainly suggest ITlany other fruitful lines of investigation. The Conference 'Surfaces and Interfaces of Glass and CeraITlics' held at the New York State College of CeraITlics at Alfred University under the sponsorship of the U. S. ArITly Research Office, DurhaITl, and the National Aeronautics and Space AdITlinistration, in August 1973, was tenth in the Uni versity Series in CeraITlic Science, held in rotation aITlong North Carolina State University, the University of California at Berkeley, the University of Notre DaITle and Alfred Uni versity. The chapters are arranged in order of their particular eITlphasis beginning with those principally concerned with analytical ITlethods. Chapters dealing with friction and wear follow, highly topical in the present-day concern with effi cient use of energy in finishing processes, on the one hand, and the avoidance of preITlature failure by frictional daITlage to ITloving parts on the other. Surface reactions are then considered, including the iITlportant questions of physiological interactions with ceraITlic candidates for prosthetic applica tions. Material-ITlaterial interfaces and transition zones are discussed through exaITlples which include grain bound aries in ceraITlics as well as interfaces aITlong various solid, liquid and gaseous phases. 564 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Although the field of contemporary immunobiology continues to diversify and encompass an increasing array of biomedical disciplines and topics, there are frequently several themes that will receive special emphasis and prominence at… any given time. It is our hope that this series will reflect these themes and pro vide an appropriate venue for exposure of such topics at a useful time. Although this particular volume is not designated as one of the special topics volumes in this series, the selected topics have in essence come together to con sider aspects of two major areas of considerable research interest in immuno biology today. These concern new approaches and insights into an understanding of the tumor-host relationship, and aspects of cellular interactions and networks as approached by various different lines of investigation. The province of tumor immunology remains one of the most challenging areas to immunologists, as it of necessity involves not only developing an under standing of the neoplastic process itself and how the immune system responds, but of eventually using this information in a diagnostic or therapeutic manner. 316 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Ten years ago the Sunnner Institute on 'Trends in Particle The ory' was held in Bonn. Among other subj ects J. Wess spoke on his work wi th B. ZlDllino on 'Fermi - Bose-Supersymmetry'. In the meantime this subject has developed into… one of the most exciting fields of research and the Bonn Summer Institute (August 20 - August 31 1984) was devoted exclusively to supersymmetry. The main aim of the Summer Institute was to provide a compre hensive introduction for mainly young post-doctoral theoretical physicists to the currently most discussed subjects in supersynnne try and supergravity. The intention was to emphasize the pedagogi cal presentation. The seminars given in addition to the introduc tory lectures treat more specialized subjects and are closer to research reports. Since the topics, ranging fromalgebraic structures to experimental implications do not arrange easily in a one-dimension al array, the lectures are reproduced in alphabetic order of the lec turers. The Summer Institute was made possible by the NATO Advanced Study Programme, additional support was granted by the Bundesmi nisterium für Forschung und Technologie and the Ministerium für Wissenschaft und Forschung of Nordrhein-Westfalen. We gratefully acknowledge their cooperation. It is a pleasure to thank the lecturers and seminar speakers for the effort invested in the presentation of the lectures and in their collaboration in preparing the written notes. 720 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -For well over a decade, the numerical approach to field computation has been gaining progressively greater importance. Analytical methods of field compu tation are, at best, unable to accommodate the very wide variety of configura t…ions in which fields must be computed. On the other hand, numerical methods can accommodate many practical configurations that analytical methods cannot. With the advent of high-speed digital computers, numerical field computations have finally become practical. However, in order to implement numerical methods of field computation, we need algorithms, numerical methods, and mathematical tools that are largely quite different from those that have been traditionally used with analytical methods. Many of these algorithms have, in fact, been presented in the large number of papers that have been published on this subject in the last two decades. And to some of those who are already experienced in the art of numerical field computations, these papers, in addition to their own original work, are enough to give them the knowledge that they need to perform practical numerical field computations. 240 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Fish and marine invertebrates are important sources of nutrients for the world's population, and many species have exceptionally high market value because of their exquisite sensory properties. Both the utilization of the available…catch in different forms and the market price are affected by the quality of the fish. Proteins and nonprotein nitroge nous compounds playa crucial role in the nutritional value and sensory quality of seafoods as well as in the suitability of different species to various forms of processing, preservation, and use in other branches of the food industry. This role of proteins results from their basic chemical and biochemical properties and functions in different tissues. A presenta tion of the actual state of knowledge on seafood nitrogenous compounds in one volume may contribute to a better understanding of the involve ment of these components in all stages of handling and processing fish. It has been possible to prepare this text thanks to the cooperative effort of an international group of specialists. The editors of the book are greatly indebted to all colleagues who have willingly contributed to this volume, sharing their knowledge and experience, as well as to all persons who have granted permission to use their previously published materials. viii Preface ix A large part of the book has been prepared during my sabbatical in the Department of Marine Food Science, National Taiwan Ocean University (NTOU) in Keelung, Taiwan. 248 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The 1978 Advanced Study Institute in Nuclear Theory devoted to common problems in Low and Intermediate Energy Nuclear Physics was held at the Banff Centre in Alberta, Canada from August 21 through September 1, 1978. The present volu…me contains the text of 25 lectures and seminars given at the Institute and illustrates the directions that nuclear physicists are taking in the evolution toward a unified picture of low, medium and high energy phenomena. Recent attempts at unifying the weak and electromagnetic inter action in particle physics have led naturally to question their role in nuclei. The success of the quark model at interpreting the new resonances in high energy physics makes it imperative to consider their role in dealing with nuclear physics problems at the microscopic level. Is our present knowledge of the nuclear potential consistent' with recent experimental evidence at low and medium energy and can it correlate meaningfully nuclear and pion physics phenomena These are some of the fundamental questions debated in this book attempting to offer a consistent picture of the nuclear system as it emerges using the electromagnetic, weak and strong interaction probe. The lectures and seminars forming the present volume have been divided into four sections dealing with a) the weak interaction, b) quarks and nuclear structure, c) physics of electrons, protons and kaons, and finally d) pion physics. 692 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The importance of gauge theory for elementary particle physics is by now firmly established. Recent experiments have yielded convincing evidence for the existence of intermediate bosons, the carriers of the electroweak gauge force,…as well as for the presence of gluons, the carriers of the strong gauge force, in hadronic interactions. For the gauge theory of strong interactions, however, a number of important theoretical problems remain to be definitely resolved. They include the quark confinement problem, the quantitative study of the hadron mass spectrum as well as the role of topology in quantum gauge field theory. These problems require for their solution the development and application of non-perturbative methods in quantum gauge field theory. These problems, and their non-perturbative analysis, formed the central interest of the 1983 Cargese summer institute on 'Progress in Gauge Field Theory. ' In this sense it was a natural sequel to the 1919 Cargese summer institute on 'Recent Developments in Gauge Theories. ' Lattice gauge theory provides a systematic framework for the investigation of non-perturbative quantum effects. Accordingly, a large number of lectures dealt with lattice gauge theory. Following a systematic introduction to the subject, the renormalization group method was developed both as a rigorous tool for fundamental questions, and in the block-spin formulation, the computations by Monte Carlo programs. A detailed analysis was presented of the problems encountered in computer simulations. Results obtained by this method on the mass spectrum were reviewed. 620 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This publication is the Proceedings of the NATO Advanced Research Workshop (ARW) on the Dynamics of Polyatomic Van der Waals Molecules held at the Chateau de Bonas, Castera-Verduzan, France, from August 21 through August 26, 1989. V…an der Waals complexes provide important model problems for understanding energy transfer and dissipation. These processes can be described in great detail for Van der Waals complexes, and the insight gained from such studies can be applied to more complicated chemical problems that are not amenable to detailed study. The workshop concentrated on the current questions and future prospects for extend ing our highly detailed knowledge of triatomic Van der Waals molecule dynamics to polyatomic molecules and clusters (one molecule surrounded by several, or up to sev eral tens of, atoms). Both experimental and theoretical studies were discussed, with particular emphasis on the dynamical behavior of dissociation as observed in the dis tributions of quantum states of the dissociation product molecules. The discussion of theoretical approaches covered the range from complete ab initio studies with a rig orous quantum mechanical treatment of the dynamics to the empirical determination of potential energy surfaces and a classical mechanical treatment of the dynamics. Time independent, time dependent and statistical approaches were considered. The workshop brought together experts from different fields which, we hope, benefited from their mutual interaction around the central theme of the Dynamics of Van der Waals complexes. 556 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Oata Analysis and Synthesis (CINOAS) \* at Purdue. University in 1957, starting its coverag…e 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 tional publishing house to assure improved service and broader dissemination. 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 33 (thesis year 1988) a total of 13,273 theses titles from 23 Canadian and 1 85 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. While Volume 33 reports theses submitted in 1988, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time. 440 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This volume constitutes the written proceedings of the Third International Conference on Materials SCience, held under the sponsorship of the Accademia Nazionale dei Lincei as the XIII summer course of the G. Donegani Foundation at…Tremezzo, Italy, on September 4-15, 1972. The course of lectures was designed for scientists and engineers 'd th a ,wrking knowledge of electronic materials, who sought to extend their knowledge of the newest developments in the field. The rapid pace of research and exploratory development in electronic materials has led to a preSSing need for continuing awareness and assessment of new electronic materials, as well as renewal of information in the more traditional areas. Three classes of electronic materials were selected for the course. Semiconductors provide the foundation for solid state electronics and semiconductor devices represent the most sophisti cated and advanced application of materials science and engineering known to modern technology. Yet, the march of progress in semi conductors continues ,unabated - new semiconductor materials are in the research stage, new process technology is being developed, and new devices are being conceived. The second class of materials dealt with in the course, magnetic alloys and insulators, also has a firm application base; for example, computer performance is often measured in terms of the size of the magnetic memory. The tailoring of materials to provide particular combinations of desired magnetic properties is an integral part of the development of the electronics, just as in the case of semiconductors. 660 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The present stage of technological development makes new and ever more complex demands on materials that have to work under conditions of high temperature and pressure, in high vacuum, and in corrosive media. In consequence special…importance is now at tached to the refractory compounds of transition metals of groups IV to VI with such nonmetals as boron, carbon, silicon, and nitro gen. These compounds possess high melting points, great hard ness, and high refractory and corrosion-resisting properties. The most widely used and important compounds of this type from a technological point of view are the carbides, which are already fairly widely used in various fields of technology. The present collection of papers contains the results of re cent investigations into methods of producing high-purity carbides and also components made of the carbides and their alloys. Great attention has been paid to the study of a wide range of properties of the carbides and of alloys based on them, viz., the electro-and thermophysical, thermodynamic, mechanical, and chemical prop erties, and also to the utilization of the carbides as wear-and abrasion-resistant materials. In contrast to many previous publications dealing with carbides, the results presented in this collection relate to the properties of carbides having a definite phase composition, corresponding to a higher degree of purity 0 In some of the contributions the physical and chemical properties of the carbides are interpreted in terms of certain solid-state models and concepts concerning the types of chemical bonding in these compounds. 476 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This volume records the proceedings of an International Symposium on The Structure and Function of Gangliosides, held at Le Bischenberg, Alsace, France, in April 23-27, 1979. The meeting was convened to get a comprehensive view of t…he immense activity that had occurred in the field since the previous conference on gangliosides held at Mont Sainte-Odile, ~lsace, France, in April 1973. At a conference on Enzymes of Lipid Metabolism held at the same place in April, 1977, several of the participants from the first ganglioside conference in 1973 met again. All previous participants agreed that the first meeting with its many frank and stimulating lectures, round tables and informal discussions had been of tremendous importance for the activity in the field and led to many personal contacts and a warm friendship among the ganglioside researchers. The success of the first meeting must be ascribed largely to one single man, PAUL MANDEL. Therefore, we decided to dedicate the next ganglioside conference to hirn and I was given the privilege to arrange the meeting together with him and staff members at Centre de Neurochirnie, Strasbourg. The Symposium on The Structure and Function of Gangliosides was arranged to honour PAUL MANDEL for his unique and never failing efforts to promote and strengthen international col laboration in all fields of neurochemistry. 588 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume, the fourth in the series 'The Prostagiandin System', contains most of the presentations at the International School of Pharmacology on 'Drugs Effecting Leukotrienes and other Eicosanoid pathways' held in Erice, Sicily,…at the 'Ettore Majorana Center' on 9-20 September 1984. The discovery of a new class of biologically active compounds is always exciting even if at the present time knowledge is advancing very rapidly; this is particu1arly true for the eicosanoids. Evidence for a pivotal role of arachidonic acid as a precursor of mediators and modulators of various cell functions is now weil established. This broad knowledge has stimulated the search for drugs capable of interfering with the eicosanoid system and since the discovery of the mechanism of action of Aspirin, new drugs have become available in order to act more specifica11y not only at the level of different enzymes involved in arachidonic acid conversion but also more selectively at the receptor si tes where the acti ve metaboli tes are effecti ve. In addition to this, several stable synthetic derivatives of endogenous unstable prostanoids mimicking their functions in a variety of physiopatho19gical processes are also of potential therapeutic interest. This volume will certainly help scientists and students wi th different interests related to those diseases that stern from arachidonic acid metabolites interactions in hypersensitivity phenomena and in host defence mechanisms. 408 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The present volume of this series, following the tradition of the previous volumes, covers three major lines of research on crystallization: growth from vapor and epitaxy, growth from solution, and growth from melt. As in the previo…us volumes, preference is given to papers that provide original results and reviews of results obtained by the authors and those from published sources, although some of the papers are either purely original or purely of review character. The first section deals with crystal growth from vapor and epitaxy and contains three papers. One of them, on artificial epitaxy, discusses and reviews published results from the last three years in this rapidly developing area. The results are used in outlining mechanisms for oriented film growth on amorphous substrates. Another paper in this section deals with classical epitaxy, namely oriented growth on single-crystal substrates, where some important conclusions are drawn from the growth of gallium nitride films on sapphire, which concern the orientation relationships in that pair of substances. The last paper in the section deals with film growth under ion bombardment (the corresponding techniques in film crystallization have already advanced from theory to practical applications). 240 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The tenth meeting of the International Foundation for Biochemical Endocrinology was held in Geilo, Norway near the end of September, 1982. The subject matter of the conference and the monograph was on 'Regulation of Target Cell Resp…on siveness.' The local organizing committee was Asbj~rn Aakvaag and Vidar Hansson. The scientific sessions covered a wide range of hormone action and cell response, including: peptide hormones and target cell response, regulation of insulin responsiveness, intracellular modulation of peptide hormone response, gonado tropins and target cell responses, hypothalamic hormone- effects and regulation, steroid receptors and cellular control, hormones and growth regulation, and hormones and gene regulation. The chairpersons for the sessions were L. Birnbauer - A. Aakvaag, S. Taylor - R. S. Horn, F. Labrie - F. Rommerts, A. R. Means - K. W. McKerns, P. F. Hall - V. Hansson K. Griffiths - K. M. Gautvik, E. J. Peck, Jr. - E. Haug, F. S. French - W. T. Schrader, and E. M. Ritzen - B. Jegou. In addition to the scientific sessions in Geilo we were all delighted to sample some of the cultural and artistic attractions of Oslo, and to travel by train from Oslo via Geilo to Bergen. The scenery and hospitality were magnifi cant. 568 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The last decade has been marked by a rapid growth in statistical mechanics, especially in connection with the physics and chemistry of the fluid state. Our understanding in these areas has been considerably advanced and enriched by…the discovery of new techniques and the sharpening of old techniques, ranging all the way from computer simulations to mode-mode coupling theories. Statistical mechanics brings together under one roof a broad spectrum of mathematical methods. The aim of these volumes is to provide a didactic treatment of those topics that are most useful for the study of problems of current interest to theoretical chemists. The emphasis throughout is on the techniques themselves and not on reviewing the enormous literature in statistical mechanics. Each author was charged with the following task. Given N pages, (a) pose the problem, (b) present those aspects of the particular technique that cJearly illustrate its internal workings, (c) apply the technique to the solUlion of several illustrative examples, and (d) write the chapter so that it will enable the reader to approach key citations to the literature intelligently. These volumes are designed for graduate students and research workers in statistical mechanics. Nevertheless, they should be useful in other areas as weIl. 384 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The juvenile hormones of insects are unique molecules in terms of their chemical nature (methyl esters of sesquiterpene epoxides) and action (both as modulators of morphogenesis during the larval life of insects and as a gonadotropi…c agent in many female adults). Although a symposium dedicated to the chemistry, metabolism and effects of juvenile hormone at a number of levels would be merited on the basis of its interest to the chemist, physiologist, endo crinologist, developmental biologist and entomologist, the juvenile hormones are special in the sense that juvenile hormone mimics (juvenoids, insect growth regulators, analogs) are currently being utilized to control various insec. t pests. Indeed, a number of commercial firms are currently developing new compounds with juven ile hormone activity that might possess a narrow spectrum of acti vity and which would be relatively biodegradable. Thus, a symposium on the juvenile hormones is also merited on a practical basis since juvenoids are already becoming constituents of our environment and it is apparent that in order to design effective mimics of the natural juvenile hormones, o~e should understand the means by which juvenile hormone elicits its effects. As will become evident to the reader, the great majority of data presented at this symposium have not been published previously and the symposium itself was organized along natural divisions dealing with the chemistry, metaoolism and multi-level modes of action of the juvenile hormones. Special lectures were presented by Professors C. M. Williams, B. W. O'Malley and W. S. 588 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -As we enter mid-19Bl, the Reagan administration is completing a review of U. s. nuclear waste management policy. Major revisions in the recently announced Carter administration policies are expected. Reagan is a strong supporter of…civilian nuclear power and will probably encourage spent fuel reprocessing by the private sector. Meanwhile, the deep geologic disposal of defense nuclear waste in New Mexico moves ahead. In the coming months, discussion and debate of U. S. radioactive waste management policies will intensify in the Congress, in the technical community, and among environ mentalists and the public at large. An important element of the debate should be the scientific and technical issues of the safe disposal of radioactive wastes from both the civilian nuclear power fuel cycle and the defense fuel cycle, including naval pro propulsion programs and nuclear weapons production. The literature of waste management is voluminous, covering all aspects of the world-wide problem of safe disposal. The authors of this book have attempted to cri tically review this literature, selecting the more important reports to abstract. Our selection criteria were heavily influenced by considerations of policy issues and by our experiences in both the technical community and the regulatory environment. Our intent is to identify those reports we feel will contribute the most to the development of a national consensus on the safe disposal of existing and future nuclear wastes as yet another U. S. waste policy emerges in Washington. 116 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Solid state physicists have long appreciated the usefulness of thermal neutron scattering in the inves tigation of condensed matter. This technique was first made possible by the advent of the nuclear reac tor and has, since then, u…ndergone many refinements. The developments in this field of research have, we felt, necessitated the making of a comprehensive compilation of the published thermal neutron papers. The large number of titles collected in this book, as well as their diversity and their yearly distribution, reflects the continued contribution of the neutron probe to our understanding of physical systems. This bibliography is an updated and improved version of the one first published by us in March of 1973 under a similar title. Many of the omissions and inconsistencies of the first edition, such as occurred, for example, in the initialing of authors' names, have been corrected. The literature search has been carried back to 1932, the year when the existence of the neutron was experimentally confirmed. Several additional journals have also been searched and brought up to date together with those listed in our first publication. The number of entries is now 8543, an increase of 65 per cent relative to the first edition. 536 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The time seems ripe for a critical compendium of that segment of the biological universe we call viruses. Virology, as a science, having only recently passed through its descriptive phase of naming and num bering, has probably reach…ed that stage at which relatively few new truly new-viruses will be discovered. Triggered by the intellectual probes and techniques of molecular biology, genetics, biochemical cytology, and high-resolution microscopy and spectroscopy, the field has experienced a genuine information explosion. Few serious attempts have so far been made to chronicle these events. This comprehensive series, which will comprise some 6000 pages in a total of about 22 volumes, represents a commitment by a large group of active investigators to analyze, digest, and expostulate on the great mass of data relating to viruses, much of which is now amorphous and disjointed and scattered throughout a wide literature. In this way, we hope to place the entire field in perspective as well as to develop an invaluable reference and sourcebook for researchers and students at all levels. This series is designed as a continuum that can be entered anywhere but which also provides a logical progression of developing facts and integrated concepts. 360 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In this NATO-sponsored Advanced Research Workshop we succeeded in bringing together approximately forty scientists working in the three main areas of structurally incommensurate materials: incommensurate crystals (primarily ferroele…ctric insulators), incommensurate liquid crystals, and metallic quasi-crystals. Although these three classes of materials are quite distinct, the commonality of the physics of the origin and descrip tion of these incommensurate structures is striking and evident in these proceedings. A measure of the success of this conference was the degree to which interaction among the three subgroups occurred; this was facili tated by approximately equal amounts of theory and experiment in the papers presented. We thank the University of Colorado for providing pleasant housing and conference facilities at a modest cost, and we are especially grate ful to Ann Underwood, who retyped all the manuscripts into camera-ready form.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book contains the proceedings of the first international symposium devoted to research on the evaluation and planning of new person-to-person telecommunication systems. It was sponsored by NATO's Special Programme Panel on Syst…ems Science and took place, in September 1977, at the University of Bergamo in the north of Italy. Telecommunication systems which provide for communication be tween people, rather than computers or other instruments, are of two kinds. There are mass communication systems (broadcast radio and television) and interpersonal systems (for example, the telephone and Telex) which join together individuals or small groups. Here we have included in the interpersonal category certain systems for re trieving information from computers, essentially those systems in which the role of the computer 1s primarily to act as a store and to identify that information which best fits a user's request. (This excludes management information systems in which the computer performs important transformation functions. ) Distinctions between interpersonal and mass communication sys tems, and between these two and da ta communication systems, are increasingly breaking down for those who provide the services. (In the U. K. broadcasters are piloting information retrieval services and the British Post Office is competing with a more sophisticated sys tem which could also be used for the exchange of messages. Elsewhere computer da ta networks are increasingly employed for the exchange of personal messages. 800 pp. Englisch.
