Taschenbuch. Etat : Neu. Neuware -This volume gathers the invited talks of the XIII International Work shop on Condensed Matter Theories which took place in Campos do Jordao near Sao Paulo, Brazil, August 6-12, 1989. It contains contributions in a wide variety of fields including neutral quantum and classical fluids, electronic systems, composite materials, plasmas, atoms, molecules and nuclei, and as this year's workshop reflected the natural preoccupation in materials science with its spectacular prospect for mankind, room tempera ture super-conductivity. All topics are treated from a common viewpoint: that of many-body physics, whether theoretical or simu1ational. Since the very first workshop, held at the prestigious Instituto de Fisica Teorica in Sao Paulo, and organized by the same organizer of the 1989 workshop, Professor Valdir Casaca Aguilera-Navarro, the meeting has taken place annually six times in Latin America, four in Europe and three in the United States. Its principal objective has been to innitiate and nurture collaborative research networks of scientists interested in the IDultidisciplinary aspects of many-body theory applied to problems in con densed-matter physics. Financial as well as moral support is gratefully appreciated by all: of the CLAF in Rio, the CNPq in Brasilia, the FAPESP and the FUNDUNESP in Sao Paulo, and the U.S. Army Research Office in Durham, NC, USA.…

Taschenbuch. Etat : Neu. Neuware - We are again proud to present an excellent volume of contemporary topics in NMR and EPR to the biological community. The philosophy behind the volume and the presentation of each chapter remains at the high level reflected in our earlier volumes: to be current, pedagogical, and critical. The first chapters, as always, address a subject related to in-vivo biology. Gabby Elgavish addresses NMR spectroscopy of the intact heart. lain Campbell and colleagues present a state-of-the-art description of NMR methods for probing enzyme kinetics in intact cells and tissues. Klaus Mobius and Wolfgang Lubitz have produced a thorough review of the principles and applications of ENDOR spectroscopy in photobiology and biochemistry including discussions of liquid and solid state ENDOR as well as CIDEP-enhanced ENDOR. The final chapter by Hans Vogel and Sture Forsen addresses a contemporary problem in inorganic biochemistry, namely cation binding to calcium binding proteins. We are pleased to announce that a special forthcoming volume will be devoted entirely to the subject of 'Spin Labeling: Theory and Applications (3rd compendium).' A substantial degree of progress has occurred in this important area of ESR in biology since the last treatise on the subject in 1979. Lastly, we acknowledge our colleagues in the field who continue to support this excellent series both as subscribers and contributors. We pledge to continue servicing the community as long as the need exists. …

Taschenbuch. Etat : Neu. Neuware - There is much evidence to suggest that prostaglandins may have a physiological role to play in the control of thyroid gland metabolism, although the precise nature of this role remains to be defined. Prostaglandins have been found in normal thyroid tissue, and there is evidence of increased levels in some, but not all, cases of medullary carcinoma of the thyroid. which may account for the associated diarrhea. Exogenous prostaglandins, like TSH, bind to thyroid plasma mem branes, stimulate the adenylate cyclase-cyclic AMP system, thyroid hormone secretion, iodide organification, colloid droplet formation, glucose oxidation, and 32p incorporation into phospholipids. Prosta glandins of the E series are the most potent, although their maximal effects are generally less than the maximal effects of TSH. The interrelationships existing between TSH and prostaglandins have been the subject of intensive investigation, but as yet no one uni fying concept has emerged. TSH and prostaglandins have been shown to occupy different receptors on the thyroid plasma membrane. Al though TSH can increase intracellular prostaglandin levels, probably as a result of increased synthesis, prostaglandins do not appear to be essential intermediates in TSH action on adenylate cyclase. The pos sibility that prostaglandins are part of a negative feedback system con trolling TSH action is, as yet, a tentative hypothesis, and further work will be required to unravel the interrelationships between these sub stances that now appear to be far more complex than has been envisaged thus far.…

Taschenbuch. Etat : Neu. Neuware - The use of ultrasound for various diagnostic techniques in medicine continues to increase in popularity and complexity. It seems possible that the prediction of the National Science Foun dation that ultrasonic techniques may be used as frequently as X-ray techniques by the end of the decade may indeed be fulfilled. The annual scientific meeting of the American Institute of Ultra sound in Medicine is the only meeting held regularly on the North American continent and devoted solely to the diagnostic use of ultrasound. Under these circumstances it is not surprising to find that both the attendance at these meetings and the number of papers submitted for presentation, are increasing markedly each year. The papers presented at these meetings probably reflect the 'state-of-the-Art' reasonably accurately. The Proceedings of these annual meetings are therefore a valuable record of the current state of ultrasonic diagnostic techniques in the U.S.A. Even though it is not possible to print in extenso every paper presented at the meeting, an attempt has been made with this volume, by increasing the length of the papers printed in abstract form, to enable the reader to obtain an overall view of current developments and research on this continent in all fields of ultrasonic medical diagnostic technology. Speed of publication is essential if this volume is to contain current information.…

Taschenbuch. Etat : Neu. Neuware - Kinetic models have often served as useful examples in develop ing the methodology for the design and analysis of experiments in volving mechanistic models. Thus, it is not surprising that these approaches have been applied quite successfully to kinetic obser vations. Nevertheless, many ideas and methods were developed indepen dently in various fields of science. More often than not, investi gators working in one area have not been aware of relevant advances in others. In order to facilitate the desirable exchange of ideas, a one-day symposium was held in Toronto in conjunction with the XIth International Congress of Biochemistry. Biochemists, pharmacolo gists, and statisticians came together and discussed many of the topics presented in this volume. Participants in the symposium believed that it would be use ful to publish a collection of the presentations together with some additional material. The present volume is the result. It is an attempt to convey some of the interdisciplinary concerns involv ing mechanistic, and especially kinetic, model building. The coverage is by no means exhaustive: many principles, methods, and problems are not included. Even the applications are limited to biochemistry and pharmacology. Still, the symposium highlighted areas of current interest. These included questions of weighting, robust parameter estimation, pooled data analysis, model identification, and the design of experiments. These topics, which are of interest in many fields of science, are discus3ed also in the present volume.…

Taschenbuch. Etat : Neu. Neuware - A modern microelectronic circuit can be compared to a large construction, a large city, on a very small area. A memory chip, a DRAM, may have up to 64 million bit locations on a surface of a few square centimeters. Each new generation of integrated circuit- generations are measured by factors of four in overall complexity -requires a substantial increase in density from the current technology, added precision, a decrease of the size of geometric features, and an increase in the total usable surface. The microelectronic industry has set the trend. Ultra large funds have been invested in the construction of new plants to produce the ultra large-scale circuits with utmost precision under the most severe conditions. The decrease in feature size to submicrons -0.7 micron is quickly becoming availabl- does not only bring technological problems. New design problems arise as well. The elements from which microelectronic circuits are build, transistors and interconnects, have different shape and behave differently than before. Phenomena that could be neglected in a four micron technology, such as the non-uniformity of the doping profile in a transistor, or the mutual capacitance between two wires, now play an important role in circuit design. This situation does not make the life of the electronic designer easier: he has to take many more parasitic effects into account, up to the point that his ideal design will not function as originally planned. …

Taschenbuch. Etat : Neu. Neuware - W. HANLE and H. KLEINPOPPEN In 1919, in the first edition of Atombau and Spektrallinien, Sommerfeld referred to the immense amount of information which had been accumu lated during the first period of 60 years of spectroscopic practice. Sommer feld emphasized that the names of Planck and Bohr would be connected forever with the efforts that had been made to understand the physics and the theory of spectral lines. Another period of almost 60 years has elapsed since the first edition of Sommerfeld's famous monograph. As the editors of this monograph, Progress in Atomic Spectroscopy, we feel that the present period is best characterized by the large variety of new spec troscopic methods that have been invented in the last decades. Spectroscopy has always been involved in the field of research on atomic structure and the interaction of light and atoms. The development of new spectroscopic methods (i.e., new as compared to the traditional optical methods) has led to many outstanding achievements, which, together with the increase of activity over the last decades, appear as a kind of renaissance of atomic spectroscopy.…

Taschenbuch. Etat : Neu. Neuware - This Volume contains the papers presented by twenty-eight invited speakers at the symposium entitled, 'Genetic Manipulation of Woody Plants,' held at Michigan State University, East Lansing, Michigan, from June 21-25, 1987. Also included are abstracts of contributed poster papers presented during the meeting. That the molecular biology of woody plants is a rapidly expanding field is attested to by the large attendance and high level of enthusiasm generated at the conference. Leading scientists from throughout the world discussed challenging problems and presented new insights into the devel opment of in vitro culture systems, techniques for DNA analysis and manipulation, gene vector systems, and experimental systems that will lead to a clearer understanding of gene expression and regulation for woody plant species. The presence at the conference of both invited speakers and other scientists who work with nonwoody plant species also added depth to the discussions and applicability of the information presented at the conference. The editors want to commend the speakers for their well-organized and informative talks, and feel particularly indebted to the late Dr. Alexander Hollaender and others on the planning committee who assist ed in the selection of the invited speakers. The committee consisted of David Burger (University of California, Davis), Don J. Durzan (University of California, Davis) , Bruce Haissig (U. S. Department of Agriculture Forest Service), Stanley Krugman (U. S. Department of Agriculture Forest Service) , Ralph Mott (North Carolina State University), Otto Schwarz (Univer.sity of Tennessee, Knoxville), and Roger Timmis (Weyerhaeuser Company).…

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book is an attempt to share some of the fascinating and exciting ideas of modern theoretical physics with a non-mathematical audience. I also hope to give some appreciation of the exceptionally creative people who have generated these ideas. I had no intention of writing a comprehen sive history of these ideas, however; I apologize to those physicists whose important contributions I may have omitted. Several people have contributed directly to the writing of this book, and I would like to take this chance to thank them. Clive Horwood of Praxis Publishing and Paul Farrell of Copernicus Books have both been supportive of the project. Anna Painter has been an exceptionally thorough editor and has provided invaluable advice. Dr John Mason and Lyman Lyons both offered constructive criticism of an early draft. The errors that remai- and errors and misinterpretations are inevitable in any attempt to explain the subtle ideas of theoretical physics without the aid of mathematics - are my sole responsibility. I would like to thank Ron, Ronnie, Peter, Jackie, Emily, and Abigail for their support. And, most importantly, I would like to thank Heike and Jessica for their patience.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Distributed service networks encompass various facilities with which we have daily contact. In the public sector they include, for instance, ambulance, fire, and police services; in the business sector they include maintenance and repair services, road services, courier services, and the like. Policy making problems in distributed service networks can be clearly classified into a number of hierarchical levels. The levels are distinguished by the time horizon of the problem, by the amount of cost involved in the implementation of a solution, and by the political implications of the solution. This top-down classification is typical of what is known as the 'systems approach,' advocating that the direction of the analysis of complex systems should be from the whole to the details. The top-down classification consists of the following categories of policies: 1. Zoning: How should a network be partitioned into subzones 2. Station location: Where should service stations or service units be located 3. Resource allocation: What amount of resources should be allocated to the stations vii viii Preface 4. Dispatching, routing, and repositioning: What is the optimal dis patching policy, what are the optimal routes for nonbusy units, and under what circumstances is it worthwhile to reposition a certain idle unit A top-down approach implies that each of the problems is solved separately; however, the solution of a higher-level problem sets constraints on problems at lower levels. 312 pp. Englisch.…

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -As its name suggests, the 1988 workshop on 'Interacting Electrons in Reduced Dimen the wide variety of physical effects that are associated with (possibly sions' focused on strongly) correlated electrons interacting in quasi-one- and quasi-two-dimensional mate rials. Among the phenomena discussed were superconductivity, magnetic ordering, the metal-insulator transition, localization, the fractional Quantum Hall effect (QHE), Peierls and spin-Peierls transitions, conductance fluctuations and sliding charge-density (CDW) and spin-density (SDW) waves. That these effects appear most pronounced in systems of reduced dimensionality was amply demonstrated at the meeting. Indeed, when concrete illustrations were presented, they typically involved chain-like materials such as conjugated polymers, inorganic CDW systems and organie conductors, or layered materials such as high-temperature copper-oxide superconductors, certain of the organic superconductors, and the QHE samples, or devices where the electrons are confined to a restricted region of sample, e. g. , the depletion layer of a MOSFET. To enable this broad subject to be covered in thirty-five lectures (and ab out half as many posters), the workshop was deliberately focused on theoretical models for these phenomena and on methods for describing as faithfully as possible the 'true' behav ior of these models. This latter emphasis was especially important, since the inherently many-body nature of problems involving interacting electrons renders conventional effec tive single-particle/mean-field methods (e. g. , Hartree-Fock or the local-density approxi mation in density-functional theory) highly suspect. Again, this is particularly true in reduced dimensions, where strong quantum fluctuations can invalidatemean-field results. 420 pp. Englisch.…

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -It is now well established that laser flow-measuring systems have important advantages over more conventional techniques both for industrial and laboratory applications. These fundamental advantages are indicated by the enormous research effort which has gone into their development over the last decade and by the number of commercial systems which have become available. Although the field is still developing, the most important theoretical results required for relating the system outputs to the fluid flow parameters have now been formulated and a book on the subject therefore seems timely. In the text we have tried to collect together the most important results both from our own papers and from publications by other authors and to present these in a concise and easily readable form. Emphasis has been placed on the fundamental theory and limitations associated with the various techniques rather than on detailed description of specific systems. We have also included a number of new results on areas such as photon counting in turbulent and periodic flows, frequency domain and time domain analysis of laser Doppler velocimeter signals, effect of background noise on system performance, and on cross-correlation techniques for diffusing flows. 308 pp. Englisch.…

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -How do we recognize that the number . 93371663 . . . is actually 2 IoglQ(e + 7r)/2 Gauss observed that the number 1. 85407467 . . . is (essentially) a rational value of an elliptic integral-an observation that was critical in the development of nineteenth century analysis. How do we decide that such a number is actually a special value of a familiar function without the tools Gauss had at his disposal, which were, presumably, phenomenal insight and a prodigious memory Part of the answer, we hope, lies in this volume. This book is structured like a reverse telephone book, or more accurately, like a reverse handbook of special function values. It is a list of just over 100,000 eight-digit real numbers in the interval [0,1) that arise as the first eight digits of special values of familiar functions. It is designed for people, like ourselves, who encounter various numbers computationally and want to know if these numbers have some simple form. This is not a particularly well-defined endeavor-every eight-digit number is rational and this is not interesting. However, the chances of an eight digit number agreeing with a small rational, say with numerator and denominator less than twenty-five, is small. Thus the list is comprised primarily of special function evaluations at various algebraic and simple transcendental values. The exact numbers included are described below. Each entry consists of the first eight digits after the decimal point of the number in question. 436 pp. Englisch.…

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -February 14, 1968 marked the thirtieth year since the death of Edmund Landau. The papers of this volume are dedicated by friends, students, and admirers to the memory of this outstanding scholar and teacher. To mention but one side of his original and varied scientific work, the results and effects of which cannot be dis cussed here, Edmund Landau performed one of his greatest services in developing the analytic theory of prime numbers from a subject accessible only with great difficulty even to the initiated few to the general estate of mathematicians. With the exception of the work of Chebyshev, Riemann, and Mertens, before Landau the problems of this theory were attempted only in a number of papers which were filled with gaps and errors. These problems were such that even Gauss abandoned them after several attempts in his youth, and they were described by N. H. Abel in a letter of 1823 and by O. Toeplitz in a lecture in 1930 as the deepest part of mathe matics. Clarification first began with the papers of Hadamard, de la Vallee Poussin, and von Mangoldt. At the end ofthe foreword to his work' Handbuch der Lehre von der Verteilung der Primzahlen' which appeared in 1909, Landau could thus remark with complete justification: ' . . . The difficulty of the previously unsolved problems has frightened nearly everyone away from the theory of prime numbers. 360 pp. Englisch.…

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Stanley Friedman University of Illinois Urbana, Illinois A perusal of the table of contents of this short symposium on Insect Endocrinology might lead those who are generally unin structed in Fraenkel's activities to wonder as to our choice of papers. Our justification is based upon our effort to concentrate the symposium upon a single area in which he has had an extended involvement: namely, the metamorphic molt in flies. In so doing, we immediately recognized the enormous humoral and physiological ramifications, both direct and indirect, of such an interest. Our selection of these papers is an attempt to present the broad picture with a few quick strokes. The first offering, by J. H. Willis, et al., is a direct outgrowth of Fraenkel's work with Rudall on the chemistry of the puparium. Their investigations on the structure of fly cuticle and its changes at pupariation (Fraenkel and Rudall, 1940, Proc. Roy. Soc. London (~) 129:1; 1947, ibid, 134:111), provided quanti tative data which have,since that time, influenced our ideas con cerning cuticular changes at metamorphosis and are presently at the center of the controversy over the mechanism of cuticular hardening and darkening (see Hillerton and Vincent, 1979, l.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A psychoanalyst, through training and experience, directs the en tire focus of his attention to registering and internalizing the in put of a patient's communications, listening intently for their implied meanings. It is only by umaveling the mysteries of an un conscious realm of mental activity that it becomes possible to fully comprehend the way in which mental productions are finally ob servable. The psychoanalyst's total personality is the listening in strument, and the messages emanating from this hidden sector most clearly heard, deciphered, and understood are those most resonant with the contents of the psychoanalyst's unconscious. It is probable that a variety of psychoanalysts adopting a listening posture with a given patient would hear and understand a mul tiplicity of different meanings. Over the years, sensitive, well trained psychoanalytic investigators have formulated concepts con cerning mental functioning from disparate and often opposing points of view. These contradictory ideas are offered from a ba sic theoretical foundation placing unconscious mental events as the most important force shaping human experience. Divergent opin ions may at times appear irreconcilable and then serve as the grounds for developing a separate psychoanalytic school of thought. It is not surprising that an exploration of unseen powerful and regressive forces, by a group of scientists with unique in dividual experiences, would yield insights sensitively attuned to a wide variety of important factors determining human develop ment and behavior. 372 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -In 1970, under the sponsorship of Oak Ridge Associated Univer sities (ORAU), a group of clinical investigators formed the Cooper ative Group to Study Localization of Radiopharmaceuticals. The first radiopharmaceutical selected for study was 67-Gallium (67-Ga) administered as the citrate. The object of the study was to de termine the usefulness of 67-Ga in the diagnosis and treatment of patients with various malignancies. Funding for the project was granted by the U. S. Atomic Energy Commission and the National Cancer Institute, National Institutes of Health (NIH). The Nuclear Medicine Department of the Clinical Center, NIH, agreed to assist ORAU with aspects of this study, particularly with 67-Ga scin tigraphy of patients with lymphoma and Hodgkin's disease. Pre liminary reports from the ORAU study are in press. Since April 1971, 67-Ga scintigraphy has gained increasing use in the study of cancer patients at the Clinical Center, NIH, where well over 1000 such patients have been examined by this method. This monograph was written to present selected examples from this group of a variety of malignancies seen in this 28-month period. No attempt has been made to correlate this overall experience statistically. Rather, this presentation is to help familiarize the practitioner of Nuclear Medicine with the wide range of usefulness for 67-Ga scintigraphy while making him aware of the variation in scan appearance and watchful of the many pitfalls of 67-Ga scan interpretation. Permission to use these patient studies and x-rays was generously granted by Dr. Paul P. 244 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -The World Congress of In Vitro Fertilization and Alternate Assisted Reproduction, held in Jerusalem, Israel, 2-7 April, 1989, was the sixth in the sequence of these Congresses, but was the first to emphasize the major importance and the place of assisted reproductive technologies in the treatment of infertility. The eternal City of Jerusalem witnessed the gathering of more than 1500 participants from allover the world who shared and exchanged knowledge and up-to-date experience in this ever-evolving field. The high quality scientific contributions to the Congress culminated in the publication of this Proceedings. It embraces all-important aspects in the field of in vitro fertilization and alternate assisted reproduction. Papers on controversies and diversities of methods to stimulate the ovaries, imaging techniques, basic research and state-of-the-art papers on ovarian physiology, the role of GnRH and its analog, clinical aspects of IVF treatment and cryopreservation, up-to-date techniques in assisted reproductive technologies that are quickly developing in conjunction with IVF, were included. When should IVF be preferable to surgery What are the ex pected up-to-date world results and what are the psychological, moral, ethical and religious implications These are all the concerns of the treating team and are addressed here. Male factor infertility remains a frustrating problem, but advances in the understanding of sperm-egg interaction, sperm evaluation and preparation are reported. Micromanipulation emerges as a possible alternative to bring some relief to this problem, but it also promises to be central in promoting the field of prenatal genetic analysis. 1100 pp. Englisch.…

The meeting was held under the auspices of the Ecosciences Panel of the N.A.T.O. Science Committee, and the organising expenses and greater part of the expenses of the speakers and chairmen were provided by N.A.T.O. The scientific programme was planned by M. W. Holdgate and M. J. Woodman, in consultation with numerous colleagues, and especially with the Administrative Director of the Conference in Iceland, Dr. Sturla Fridriksson. Iceland proved a particularly suitable location for such a Conference. Geologically, it is one of the youngest countries 1n the world, owing its origin to the up-welling of volcanic rock along the spreading zone of the mid-Atlantic ridge within the past 20 million years. Its structure, northern oceanic situation, recent glaciation and continuing volcanic activity make it distinct as a habitat and have given it a flora and fauna of especial interest. It is also a land of great natural beauty with its ice caps, waterfalls, volcanic landforms, geothermal features and dramatic coasts. In addition, its ecosystems have proved except ionally vulnerable to man's impact and it presents the kind of problem with which the Conference was concerned in an acute form. 512 pp. Englisch. …

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The present volume contains the texts of the invited talks delivered at the Fifth International Conference on Recent Progress in Many-Body Theories held in Oulu, Finland during the period 3-8 August 1987. The general format and style of the meeting followed closely those which had evolved from the earlier conferences in the series: Trieste 1978, Oaxtepec 1981, Altenberg 1983 and San Francisco 1985. Thus, the conferences in this series are in tended, as far as is practicable, to cover in a broad and balanced fashion both the entire spectrum of theoretical tools developed to tackle the quan tum many-body problem, and their major fields of application. One of the major aims of the series is to foster the exchange of ideas and techniques among physicists working in such diverse areas of application of many-body theories as nucleon-nucleon interactions, nuclear physics, astronomy, atomic and molecular physics, quantum chemistry, quantum fluids and plasmas, and solid-state and condensed matter physics. A special feature of the present meeting however was that particular attention was paid in the programme to such topics of current interest in solid-state physics as high-temperature superconductors, heavy fermions, the quantum Hall effect, and disorder. A panel discussion was also organised during the conference, under the chair manship of N. W. Ashcroft, to consider the latest developments in the extreme ly rapidly growing field of high-T superconductors. 420 pp. Englisch. …

How can different numerical methods be matched together In doing so the author presents a number of useful combinations, for instance, the combination of various FEMs, the combinations of FEM-FDM, REM-FEM, RGM-FDM, etc. The combined methods have many advantages over single methods: high accuracy of solutions, less CPU time, less computer storage, easy coupling with singularities as well as the complicated boundary conditions. Since coupling techniques are essential to combinations, various matching strategies among different methods are carefully discussed. The author provides the matching rules so that optimal convergence, even superconvergence, and optimal stability can be achieved, and also warns of the matching pitfalls to avoid. Audience: The book is intended for both mathematicians and engineers and may be used as text for advanced students. 508 pp. Englisch.…

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In the last decade, neuropsychology has grown from a small subspecialty to a major component in the practice of clinical and medical psychology. This growth has been caused by advances in psychological testing (such as the Halstead-Reitan neuropsychological battery, as discussed in Chapter 5) that have made evaluation techniques in the field available to a wider audience, by advances in neuroradiol ogy and related medical areas that have enabled us to better understand the struc ture and function of the brain in living individuals without significant potential harm to those individuals, and by increased interest by psychologists and other scientists in the role that the brain plays in determining behavior. Many disorders that were believed by many to be caused purely by learning or environment have been shown to relate, at least in some cases, to brain dysfunction or damage. With the growth of the field, there has been increased interest in the work of neuropsychologists by many who are not in the field. 524 pp. Englisch.…

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume is the collection of papers presented during a four day meeting, the EMBO workshop 'Protein Conformation as an Immunological Signal' that took place at Portovenere (La Spezia), Italy, October 1-4, 1981. The motivation that drove us to organize this meeting was the feeling that distinct groups of researchers, active in key areas of modern immunology, sometimes fail to communicate with each other simply because of different traditional affiliations. Yet it is urgent that 'molecular' and 'cellular' people cooperate more if immunology is to continue the exportation of new concepts to other disciplines. In fact, the deep meaning of molecule-molecule and cell-cell interaction, the generation of signals and their effective transmission which results in elicitation, control or suppression of responses cannot be unraveled without the experts on antibody structure or complement activation sharing their views with the experts on T cell, B cell and macrophage membrane receptors as well as the experts on factors that carry the information released by these cells. Whether the meeting was scientifically fruitful, the reader can judge after having digested these pages. We, the organizers, are not sure whether the optimal amount of interaction had taken place; especially considering how hard it is to overcome the scientist's catch 22: You have to know something quite well before you get really interested in it. In any event, we are convinced that Portovenere was one of the most successful attempts we have witnessed. 524 pp. Englisch.…

Cooks This introduction has three purposes: (a) to summarize some of the chief features of energy spectrometry of ions and to sketch in a little of the background to this subject, (b) to present some simple facts about collision processes which one skilled in, say, mass spectrometry but innocent of any knowledge of bimolecular collisions might find of value, and (c) to indicate the scope and content of the volume. 1. The Subject This book takes as its subject, ion-molecule and ion-atom reactions occurring at high energies. It emphasizes the study of inelastic reactions at high energy through measurements of translational energy. The investiga tion of these reactions using other procedures has been important in the cases of the simpler systems. In particular, the emitted radiation has been investigated and this subject is therefore discussed where appropriate. For more complex species, however, there is little information available other than from energy spectra. The defining characteristic of the energy range of interest is that momentum transfer to the neutral target is negligible for small scattering angles. The result of this apparently bland condition is a welcome simplicity in the interpretation of the results of what appears to be developing into a R. G.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Neurological disorders cause untold suffering and financial burden to hundreds of thousands of people, not only to the patients, but also the relatives and society. As of today, though numerous scientists and clinicians have devoted their efforts to understand and combat these diseases, there is still no cure or satisfactory solution to the problems. Furthermore, the brain is the most essential organ of a human being. Realizing the importance of the brain, the president of the United States, George Bush, declared the 90s as the Decade of the Brain in January, 1992. Being in neuroscience research for almost three decades, I initiated, planned and organized the first international neuropharmacology symposium. After long negotiation and fund raising, with the assistance and moral support of Dr. Abel Lajtha, director ofthe Center ofNeurochem istry in New York, USA, we finally successfully put the program together. The Sun Yat-sen Foundation in China supported all the local expenses of the symposium and Sun Yat-sen University of Medicine in Guangzhou, China served as host organization. The symposium was held in Guangzhou, China, November 9-11,1992, the eve of Dr. Sun Yat-sen's birthday. Dr. Sun Yat-sen was born in Cui Heng Cun, on the outskirts of Guangzhou, China on November 12, 1866. He finished his high school education in the British and American Christian school in Honolulu, where he was exposed to Western influence. He had been long frustrated and discontented with the backwardness and corruption of the Ching Dynasty. 228 pp. Englisch.…

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The idea for this book developed during the course of several discussions among the editors while we were working together as staff scientists in the laboratories of the Clinical Neuro science Branch of the National Institute of Mental Health. It was a happy coincidence that the three of us, child psychiatrists with predominantly clinical interests, selected a collaborative bench research project involving neurotransmitter receptor characterization and regulation. We appreciated the relevance of our work to child psychiatry and wished for a forum to share the excitement we enjoyed in the laboratory with our clinical colleagues. Moreover, it seemed to us that much of the pharmacological research in child psychiatry proceeded on an empirical basis, often without a compelling neurochemical rationale. This could reflect the paucity of neurochemical data that exists in child psychiatry and the very limited understanding of the pathophysiology in most psychiatric disorders that occur in childhood. Also, we bemoaned the fact that there was a virtual absence of meaningful interchange between clinical investigators in child psychiatry and their colleagues in the neurosciences. We believed that an edited book appealing to clinicians and basic scientists could serve as an initial effort to foster interchange between them. The editors wish to emphasize that this book is viewed as only a beginning in the process of interchange that must take place. 424 pp. Englisch.…
