Taschenbuch. Condizione: Neu. Neuware - This volume contains the papers presented at the Fifth International Workshop on Database Machines. The papers cover a wide spectrum of topics on Database Machines and Knowledge Base Machines. Reports of major projects, ECRC, MCC, and ICOT are included. Topics on DBM cover new database machine architectures based on vector processing and hypercube parallel processing, VLSI oriented architecture, filter processor, sorting machine, concurrency control mechanism for DBM, main memory database, interconnection network for DBM, and performance evaluation. In this workshop much more attention was given to knowledge base management as compared to the previous four workshops. Many papers discuss deductive database processing. Architectures for semantic network, prolog, and production system were also proposed. We would like to express our deep thanks to all those who contributed to the success of the workshop. We would also like to express our apprecia tion for the valuable suggestions given to us by Prof. D. K. Hsiao, Prof. D.…

How true our perceptions really are depends upon many factors, and not least is our understanding of what light is and how it interacts with matter. It was said that the camera, the icon of light recording instruments, never lies, and in the day of the glass plate and celluloid roll-film this might well have been true. But in this modern era, with electronic cameras and computer software, it is often safe to assume that the camera always lies. The advertising images that bombard our every waking moment are manipulated in shape, profile, color, and form. In this new era, light can be manipulated with metamaterials to make one object look like another or even cause that objects to vanish, literally before our eyes; not only can the image we see be manipulated, but so can the light itself. 224 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book originates from the NATO Advanced Study Institute on Synthesis and Analysis Methods for Safety and Reliability Studies held at Sogesta Conference Centre, Urbino, Italy, 3-14 July 1978. The Institute, co-directed by Prof. E.J. Henley and Dr. G. Volta, was attended by 67 persons from twelve countries. The focus of the Institute was on theoretical and applied aspects of reliability and risk analysis methodologies. The Institute was composed of lectures, workshops and gu~ded discussions. From the large quantity of written material that was used and produced during the Institute, a number of papers introducing the most relevant research results and trends in the field have been selected. The papers have been edited, partly rewritten and rearranged in order to obtain in the end an integrat ed exposition of methods and techniques for reliability analysis and computation of complex systems. The book is divided into four sections which correspond to fairly homogeneous areas from a methodological point of view. Each section is preceded by an introduction prepared by the Editors which aims at helping the readers to put in perspective and appre ciate the contribution of each paper to the subject of the section. 476 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The first time that we, the editors of this volume, met, a chance remark by one of us, newly returned from fieldwork in Fiji, quickly led to an animated discussion of our experiences doing anthropological research with children. Following that occasion, we began to seek each other out in order to continue such conversations, because we had found no other opportunity to discuss these significant events. We knew our experiences were rich sources of cross-cultural data and stimuli to rethinking anthro pological theory and methods. A cursory review of the literature on fieldwork revealed, to our surprise, that fieldworker's experiences with children were rarely and only briefly mentioned (Hostetler and Huntington, 1970, are an early exception). In order to learn more about research that included the ethnographers' children, we organized a conference on the topic at Michigan State University on May 1, 1982. This volume includes papers from that conference, as well as insights and ideas from the formal and informal discussions among the conference participants and audience. This volume, like the conference which preceded it, is intended to be the effects of accompanying children on anthropological an exploration of field research and on the effects of fieldwork on the children themselves. Additionally, we see this book as part of an anthropological inquiry into research as a cultural process, by which is meant the effects of the researchers' cultural identity--class, gender, age, ethnicity, and other characteristics--on fieldwork. 176 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Somehow it surprises me that this book wasn't written earlier, but I'm glad it wasn't. If it had been, Frank Koch probably wouldn't have sensed the vacuum that has existed, and this practical book wouldn't have come to be. I'd like to stress practical. The book describes in a comprehensive and-more importantly-practical way how every corporation can mar shal its financial support, employee talents, and other resources to make a meaningful impact on society. I happen to be one of those corporate executives who believes that a business has a responsibility to make such an impact. My brother Peter agrees. Our father and uncle set an example for us, and the tradition goes back to our great uncles and their uncle, Levi Strauss himself. For more than 125 years Levi Strauss & Co. has shown that social responsibil ity is good business and, in recent years, that it is also compatible with dynamic growth. We are proud of that tradition and what it produced, but 1 think the modern era of social responsibility or corporate citizenship at Levi's got its impetus in 1968 with my association with the National Alliance of Businessmen. It was there that I saw what other companies were doing: innovative ways to train, to transport, to provide jobs. It opened my eyes to areas in which business could become involved, areas I never before thought of as business responsibilities-even areas where it could have an impact. 316 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -For at least 40 years there has been a great interest in the problems created by infectious airborne agents and other toxic sub stances transported through the air. During the Second World War, this problem grew out of the very high incidence of upper respira tory infections appearing in new military recruits who were brought together in very large, open quarters. As a result, very interest ing methods were developed to measure these airborne agents, espe cially bacteria, and some important methods were refined for their control. These methods primarily concentrated on ultraviolet radia tion, propylene glycol and other means to reduce the dust in an en vironment. Because of the specialized circumstances at that time the whole consideration of airborne particles became prominent. Now, with the new strides in the recognition of mutagenic and carcinogenic effects attributed to exposure to airborne chemicals from today's technology, the problem has again become quite promi nent. The development of experimental chambers has made it possible to conduct studies under carefully controlled conditions. 676 pp. Englisch.…

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

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -nd The 22 meeting of the International Society on Oxygen Transport to Tissue (LS. O. T. T. ) of which this volume is the scientific proceedings, was held in Istanbul, Turkey on August 22-26, 1994. It was a historical occasion in that it was almost 200 years to the day that one of the founding fathers of oxygen research, Antoine Lavoisier, on May 8, 1794 found his early demise at the hands of the guillotine. This spirit of history set the tone of the conference and in the opening lecture the contribution that this part of the world has given to the understanding of oxygen transport to tissue was highlighted. In particular, the contribution of Galen of Pergamon (129-200) was discussed who for the first time demon strated that blood flowed through the arteries and whose view on the physiology of the circulation dominated the ancient world for well over a millennium. A forgotten chapter in the history of the circulation of the blood is the contribution made by Ibn al Nafis of Damascus (1210-1280) who for the first time described the importance of the pulmonary circulation by stating that all venous blood entering the right ventricle ofthe heart passes to the left ventricle, not through pores in the septum of the heart as had been postulated by Galen, but through the circulation of the lungs. 684 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Thermoelectric and related transport properties of metals have been a source of information and, also, exasperation to physicists for over a century. Perhaps the principal reasons for interest in these phenomena are their sensitivity to composition, structure and external fields and, until fairly recently, the distressing fact that often even gross experimental features such as the sign of the thermopower eluded theoretical understanding. During the past two decades many of the previously perplexing aspects of thermoelectricity have yielded to more sophisticated theoretical treat ment. As a result of this effort and concomitant experimental work using advanced measurement techniques, there is now good reason to believe that thermoelectric phenomena can shed much light on the interactions between electrons and phonons, impurities, and other defects. The last few years have witnessed new and fascinating developments that promise to stimulate new activity in this field. In contrast to the more conventional transport properties, second-and high-order contributions in electron scattering theory appear to play a profound role in thermoelectricity-the controversy surrounding ordinary and 'phony' phonon drag is far from resolved; the startlingly large effect of magnetic fields on the thermopower of metals appears to be linked intimately to scattering anisotropy; quantum oscillations of thermopower are orders of magnitude larger than corresponding oscillations of the magnetoresistance; a new approach to thermoelectric studies allows extension of thermopower measurements into the millikelvin region of temperature; finally, the advent of superconducting detection devices permits the precise measurement of extremely small voltages, an essential requirement in this field. 284 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume constitutes the proceedings of the 1983 Denver Conference on Applications of X-ray Analysis and is the 27th in the series. The conference was held jointly with the American Crystal lographic Association at Snowmass Resort, Colorado, from August 1 to 5, 1983. The papers appearing in this volume are only from pre dominantly Denver Conference (DC) sessions and from joint DC/ACA sessions. The early plans for holding a joint conference were initiated some three years ago by Q. C. Johnson of Lawrence Livermore Lab, J. B. Cohen of Northwestern University and P. K. Predecki of the University of Denver and were eventually brought to fruition by a jOint organizing committee consisting of: O. P. Anderson, Colorado State University (ACA) , D. E. Leyden, Colorado State University (DC), R. D. Witters, Colorado School of Mines (ACA) and P. K. Predecki (DC). We take this opportunity to thank the committee members and the early planners for their vision, ingenuity and hard work without which the conference would not have materialized. There was no plenary session in 1983, instead a number of special sessions were organized and chaired by various individuals. 600 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Understanding the structure and function of the blood-brain barrier (BBB) and recogniz ing its clinical relevance require a concert of scientific disciplines applied from a view point of integrative physiology rather than from only molecular or analytical approaches. It is this broad scope that is emphasized in this book. In my opinion, four original contributions define the field as it exists today. The first, a monograph by Broman,1 entitled The Permeability of the Cerebrospinal Vessels in Normal and Pathological Conditions, was the model for many subsequent clinical and 3 experimental studies on BBB pathology. Second, experiments by Davson, summarized in his book entitled Physiology of the Ocular and Cerebrospinal Fluids, indicated that passive entry of nonelectrolytes into brain from blood is governed largely by their lipid 4 solubility. This research supported the original suggestion by Gesell and Hertzman that cerebral membranes have the semipermeability properties of cell membranes. The modem era of the barrier was introduced with the 1965 paper by Crone,2 entitled 'Facilitated transfer of glucose from blood to brain tissue. ' This paper identified stereospecific, facilitated transport of glucose as part of a system of regulatory barrier properties at a time when only a barrier to passive diffusion had been contemplated. Finally, the 1967 paper by Reese and Kamovsky, 11 entitled 'Fine structural localization of a blood-brain barrier to exogenous peroxidase,' sited the barrier at the continuous layer of cerebrovascular endothelial cells, which are connected by tight junctions. 436 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This tenth volume completes the first series of 'Growth of Crystals,' which began in 1957. The sources of the volumes are as follows: for Vol. I, the 1st All-Union Conference on Crystal Growth; for Vol. 3, the 2nd; and for Vols. 5 and 6, the 3rd; Vols. 7 and 8 reported the International Symposium on Crystal Growth at the Seventh International Crystallography Con gress, and Vol. 9 the 1969 symposium on crystal growth dedicated to E. S. Fedorov; Vols. 2, 4, and 10 did not originate in conferences. The main problem that largely occupied the conferences and symposia and also the inter mediate volumes was that of real crystal formation, as well as the relation of crystal growth theory to practical crystal production. This tenth volume, which completes this first series, is to a considerable extent a survey. It contains more extensive theoretical and experimental original papers, as well as some shorter papers dealing with particular but important aspects of real crystal formation. The volume opens with a paper by V. V. Voronkov, which deals with the structure of crystal surface in Kossel's model. The model as proposed by Kossel is extremely simple. It deals qualitatively with the basic trends in the growth of an idealized crystal in its own va por at absolute zero, and naturally does not allow one to perform quantitative studies on com plex real processes. 304 pp. Englisch.…

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

In contrast, adult mice appear to be resistant to the toxic and carcinogenic effects. Newborn and infant mice are more sensitive to the effects of different hepatocarcinogens (2,3) and also to AFB , which induced hepatomas in newborn C57BL/6 x C3H FI I mice (4). A singl~ dose model of aflatoxin hepatocarcinogenesis was tested in infant C57BL/6 mice.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In the last decade, disputes between developers and local commu nities over proposed construction projects have led to increasing litiga tion. Environmental legislation, in particular, has greatly enhanced the rights and powers of organized groups that desire to participate in local development decisions. These powers have allowed citizen groups to block undesired and socially unacceptable projects, such as highways through urban areas and sprawling suburban developments. At the same time, these powers have produced a collective inability to construct many needed projects that produce adverse local impacts. Prisons, airports, hos pitals, waste treatment plants, and energy facilities all face years of liti gation before a final decision. At times, prolonged litigation has pro duced especially high costs to all participants. Despite these new powers, citizen action has often been limited to participation in public hearings or adjudicatory proceedings. Typically, this occurs so late in the decision process that citizen input has very little affect in shaping a project's design. Those who dislike some element of a project often have little choice other than to oppose the entire project through litigation. 244 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The concept of this book has developed over the past fi fteen years as interest in the water and electrolyte disturbances associated with most environmental settings moved from a research area of descriptive discovery to one dealing with the mechanisms responsible for the previously observed disturbances. Most of the contributing authors have been involved in both aspects of this evolution of research, focusing on those problems associated with body fluid and electrolyte balance and searching for hormonal explanations. What did not accompany this transition, however, was a source of information encompassing the area of interest. Instead, the previous format of environmentally focused symposia, reviews, and books continued to be the only sources available. For instance, various books deal with the physiology of high altitude, space, or exercise but do not necessarily provide adequate coverage of water and electrolyte disturbances. To our knowledge, the format of this book is unique. We have made the central focus water and electrolyte physiology with an emphasis on endocrinology and tried to comprehensively cover this area of physiology in some of the more heavily studied environments. This book too, then, will have its limitations in coverage. For instance, in-depth coverage of the respiratory and cardiovascular responses to the high altitude en vironment will not be found, but since these areas are so integrally associated with water and electrolyte regulation they are not ignored. 260 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -This volume contains papers presented at a NATO Advanced Research Institute, sponsored by their Eco-Sciences Panel, on 'The effects of acid precipitation on vegetation and soils,' held at Toronto, Canada from May 22-26, 1978. The organizing expenses and greater part of the expenses of the speakers and chair~en were provided by N.A.T.O. The scientific programme was planned by T. C. Hutchinson together with an international planning committee of G. Abrahamsen (Norway), G. Likens (U.S.A.), F.E. Last (U.K.), C.O. Tamm (Sweden) and B. Ulrich (W. Germany). Many of the dimensions of the 'acid rain' problem are common to countries of northern Europe and North America. The developing awareness over the past ten years of the international nature of the acid rain phenomenon has lead to studies documenting damaging effects on susceptible freshwater bodies. Large areas of the Canadian Pre-Cambrian Shield, with its extension into the United States, and the granitic areas of southern Norwayand Sweden contain lakes which are in the process of acidification. The biological resources of these affected areas are of considerable national concern. However, while clearly damaging effects of acidification on freshwater systems have been well documented, the impact of acid precipitation on terrestrial systems has not been so well understood. 672 pp. Englisch. …

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The practical properties of many materials are dominated by surface and near-surface composition and structure. An understanding of how the surface region affects material properties starts with an understanding of the elemental composition of that region. Since the most common contaminants are light elements (for example, oxygen, nitrogen, carbon, and hydrogen), there is a clear need for an analytic probe that simultaneously and quantitatively records elemental profiles of all light elements. Energy recoil detection using high-energy heavy ions is unique in its ability to provide quantitative profiles of light and medium mass elements. As such this method holds great promise for the study of a variety of problems in a wide range of fields. While energy recoil detection is one of the newest and most promising ion beam analytic techniques, it is also the oldest in terms of when it was first described. Before discussing recent developments in this field, perhaps it is worth reviewing the early days of this century when the first energy recoil detection experiments were reported. 468 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume is based on papers presented by invited speakers at a symposium entitled 'Plant Nitrogen Metabolism' held in conjunction with the 28th Annual Meeting of the Phytochemical Society of North America. The meeting took place on the campus of the University of Iowa at Iowa City during June 26-30, 1988, and attracted 110 participants from 11 countries. The goal of the symposium was to trace the pathway by which nitrogen passes from soil and atmosphere into both primary and secondary nitrogenous metabolites, focusing upon areas which were felt to be most rapidly expanding. From nodulines (nodule specific proteins) and GS/GOGAT mutants to sugar mimics (polyhydroxyalkaloids) and herbicide inhibitors of amino acid metabolism, research in nitrogen metabolism has expanded into areas barely envisioned only a few years ago. Both the nitrogen specialist and the general plant biochemist will be pleased by the range of topics covered here. Following an overview in Chapter 1 of plant nitrogen metabolism, the remaining chapters are loosely organized into three groups. Chapters 2-6 deal primarily with the biochemistry and molecular biology of nitrogen assimilation and transport, Chapters 7-9 with amino acid metabolism, and Chapters 10-12 with secondary metabolites. 488 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Plasma lipoproteins constitute a unique macromolecular system of lipid-protein complexes responsible for the transport of lipids from their sites of origin to their sites of utilization either as metabolic fuel or as structural components of cell membranes. Although studies on the role of lipoproteins in the mechanism of lipid transport are meritorious in their own right, the ever-increasing interest in chemical and functional properties of this remarkable class of conjugated proteins stems from the impressive evidence of their direct involvement in the genesis and develop ment of atherosclerotic lesions. The initial emphasis on neutral lipids and phospholipids as the most characteristic constituents of operationally defined lipoprotein classes has shifted in recent years to their protein moieties or apolipoproteins. The discovery of a number of apolipoproteins and characterization of familial hypolipoproteinemias as apolipoprotein deficiency disorders indicated that apolipoproteins play an essential role in maintaining the structural stability and integrity of lipoprotein particles. In addition to their role in the formation of lipoproteins, apolipoproteins were shown to perform a variety of functions in metabolic conversion of lipoproteins and their interactions with cellular surfaces. Results from several laboratories have demonstrated that the chemical and metabolic heterogeneity of operationally-defined lipoprotein classes is due to the presence of several discrete lipoprotein particles with similar physical properties but different and characteristic apolipoprotein composition. Thus, the apolipoproteins have emerged not only as essential structural and functional constituents of lipoproteins but also as unique chemical markers for identifying and classifying lipoprotein particles. 376 pp. Englisch.…

It was the fifth in a series of workshops, the first of which took place in 1984. The principal aim of these workshops is to present the state-of-the-art in scientific large scale and high speed computation. Computational science has developed into a third methodology equally important now as its theoretical and experimental companions. Gradually academic researchers acquired access to a variety of supercomputers and as a consequence computational science has become a major tool for their work. It is a pleasure to thank the Belgian National Science Foundation (NFWO-FNRS) and the Ministry of Scientific Affairs for sponsoring the workshop. It was organized both in the framework of the Third Cycle 'Vectorization, Parallel Processing and Supercomputers' and the 'Governemental Program in Information Technology'~ We also very much would like to thank the University of Antwerp (Universitaire Instelling Antwerpen - UIA) for financial and material support.

This item is printed on demand - it takes 3-4 days longer - Neuware -This volume documents the proceedings of the Symposium on Polymers in Information Storage Technology held as a part of the American Chemical Society meeting in Los Angeles, September 25-30, 1988. It should be recorded here that this symposium was cosponsored by the Division of Polymeric Materials: Science and Engineering, and the Division of Polymer Chemistry. Polymers are used for a variety of purposes in both optical and magnetic information storage technologies. For example, polymers find applications as substrate, for storing information directly, as protective coating, as lubricant, and as binder in magnetic media. In the last few years there has been a high tempo of research activity dealing with the many ramifications of polymers in the exciting arena of information storage. Concomitantly, we decided to organize this symposium and I believe this was the premier event on this topic. This symposium was conceived and organized with the following objectives in mind: (1) to bring together those actively involved (polymer chemists, polymer physicists, photochemists, surface and colloid chemists, tribo10gists and so on) in the various facets of this topic; (2) to provide a forum for discussion of latest R&D activity in this technology; (3) to provide an opportunity for cross-pollination of ideas; and (4) to identify and highlight areas, within the broad purview of this topic, which needed intensified or accelerated R&D efforts. 472 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -After the spectacular successes of the 1960's and 1970's, the mineral exploration business is at a crossroads, facing uncertain t:imes in the decades ahead. This situation requires a re-thinking of the philosophy guiding mineral exploration if it is to emulate its recent performance. The ma:i. n argument of a previous volume titled 'Designing Opt:lmal Strategies for Mineral Exploration', published in 1985 by Plenum Publishing Corporation of New York, is that a possible answer to the challenge facing mineral explorationists lies in the philosophy of opt:irn1zation. This new approach should help exploration staff make the best achievable use of the sophisticated and costly technology which is presently available for the detection of ore deposits. The main emphasis of the present volume is placed on the mathematical and computational aspects of the opt:irn1zation of mineral exploration. The seven chapters making up the ma:i. n body of the book are devoted to the description and application of various types of computerized geomathematical models which underpin the optimization of the mineral exploration sequence. The topics covered include: (a) the opt:lmal selection of ore deposit types and regions of search, as well as prospecting areas within the regions (Chapters 2, 3, 4, 6), (b) the designing of airborne and ground field programs for the opt:lmal coverage of prospecting areas (Chapters 2, 3, 4), (c) delineation and evaluation of exploration targets within prospecting areas by means of opt:irn1zed models (Chapter 5). 448 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Historically, the development of biological science has proceeded from the anatomy to the physiology of particular systems. Knowledge about neurotransmitters in the brain has evolved from the discovery of the compounds per set through the elucidation of their biosynthetic and degradative pathways, and finally to the current focus, the regulation of these processes. Regulation in a biological system implies the capacity to respond to perturbations. The introduction of standard and speci fiable disturbances in a biological system followed by examination of the mechanisms involved in response, i.e. that dampen and/or cancel the induced changes, has proved to be a successful way to elucidate regulatory mechanisms. Psychotropic drugs have been most useful to students of regula tory mechanisms in that calvarial prisoner, the brain, for they allow prospective manipulation of variables like dosage and time. Those of us interested in the biological substrata of behavior are especially excited that disturbance induced by drugs leaves the organism intact and behaving, and we can observe behavioral correlates. The pharmacological strategy is, of course, not unique to brain scientists. The relationship between psychotropic drugs and our emerging knowledge of neurotransmitter regulation is, for example, akin to the development of anticancer agents in company with the uncovering of many mysteries of molecular biology. 332 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -A 'biological clock' has now been inferred in so many and such diverse organisms and tissues that even a summary of the more interesting and important observations would be a tedious and encyclopaedic compila tion, whose bibliography would assume a daunting size. It would also be obsolescent on the day of publication. The new titles appearing in the monthly lists are scattered through many journals, but a new journal devoted exclusively to rhythm research published its first issue in May, 1970-the Journal of Interdisciplinary Cycle Research-and another, Chronobiology, appears in 1973. In this volume several authors have been asked to review separate aspects within their own fields of study, in the hope that thereby the reader might gain an idea of the many directions of active progress and be better placed to interrelate them than would be possible after a more exhaustive study of a limited part of the field. The outcome is a series of essays in which each contributor has exercised his individuality in ideas, style and presentation, and, at some points, in vocabulary, although the glossary includes a number of terms which have been fairly generally used. 344 pp. Englisch.…

This represents the fourth recent occurrence of an international conference addressing the common theme of fixed point computation. The first such conference, ti tled 'Computing Fixed Points with Applications,' was held in the Department of Mathematical Sciences at Clemson University, Clemson, South Carolina, June 26-28, 1974 and was sponsored by the Office of Naval Research and the Office of the Army Research Center. The second conference, 'Symposium on Analysis and Computation of Fixed Points,' was held at the University of Wisconsin, Madison, May 7-8, 1979, under the sponsorship of the National Science Foundation, the U. S. Army, and the Mathematics Research Center of the University of Wisconsin, Madison. The third conference, titled 'Symposium on Fixed Point Algorithms and Complementarity,' was held at the University of Southampton, Southampton, UK, July 3-5, 1979 and was sponsored by U. N. E. S. C. O. , European Research Office (London), Department of Mathematics (University of Southampton), I. B. M. U. K. , Ltd. , Lloyds Bank, Ltd. , and the Office of Naval Research (London). The Advanced Research Institute held in Sardinia was devoted to the theory and application of modern homotopy methods. The following topics were stressed: Path-Following Techniques; Bottom-Line Applications; Global vs. Classical Methods; and Sta- v vi PREFACE of-the-Art, Perspectives and Potential. 332 pp. Englisch. …
