Buch. Condizione: Neu. Neuware - In Alcohol and Hormones, leading researchers concisely review what is known about each human hormone system and how these systems are affected by alcohol use, to a lesser extent, other drugs of abuse. The contributors show clearly just how the body is regulated and how its normal functioning can be changed by alcohol.Major topics covered range from alcohol-stress interactions and the effects of alcohol on vitamin A metabolism (fetal alcohol syndrome and neural tube development) to how alcohol blocks the release of various peptide hormones, to its effects on puberty-related events in the female. There are also articles about how alcohol affects the control of body temperature, the impact of alcohol on male sexual development during puberty, the role of TRH in alcohol use disorders, and the possibility for a neuroendocrinological component in alcoholism.Alcohol and Hormones will be of interest to biomedical and alcohol researchers, neurobiologists, endocrinologists, pharmacologists, psychiatrists, and some clinicians interested in a deeper understanding of the effects of alcohol on the body.…

Buch. Condizione: Neu. Neuware - Recent advances in surgical procedures for the management of focal liver diseases have greatly increased the demand for diagnostic accuracy. So far these demands have been only partially met by further technical developments such as colour coded duplex sonography, spiral CT and marked improvements in magnetic resonance imaging. It is becoming increasingly clear that liver specific contrast media are essential for utilizing these technical developments to their fullest advantage in patient care. Against this background, a workshop was held to explore the current methods of diagnostic imaging of the liver and to try and establish a profile for the future liver specific contrast media. The pathologist's introductory and general overview is followed by chapters on the individual imaging procedures such as ultrasound, CT and MRI, so that each of the three is given the attention it deserves. The book will be of interest to radiologists from the various disciplines, and also those who plan and perform therapies, particularly surgeons and internists. …

Buch. Condizione: Neu. Neuware - Many industrialized countries are facing large problems with their public pension systems in the 21st century. An unfavourable age distribution, with lower population shares in working ages and increasing shares and numbers of elderly persons in the future will lead, under current pension systems, to a drop in contributions and at the same time to sharply rising amounts of benefits paid. This book analyzes the impact of dynamics in age structure and marital status composition on future public pension expenditures in twelve industrialized countries. It shows that there is no demographic response to population ageing at the horizon 2030. Neither an increase in fertility nor an inflow of migrants can rejuvenate national populations, unless fertility and/or migration reach unrealistically high levels. Therefore, the overall conclusion of this book is that demographic variables are of limited help to relieve the burden of future public pension expenditures. Substantial reductions of the public pension burden have to be sought in socioeconomic measures, and not in adjusting demographic conditions. The book includes various demographic and pension scenarios for pension costs in the coming decades for Austria, Canada, the Czech and Slovak Republics, Finland, France, Germany, Hungary, Italy, the Netherlands, Norway, Poland, and Sweden. Not only old age pensions, but also disability and survivor pensions have been investigated. Variant projections were calculated for changes in demographic, labour force, and pension system variables. In addition, separate case studies for three countries deal with: a pension system in Austria in which benefits depend on the number children ever born; the impact of household dynamics on social security in the Netherlands, not just marriage and marriage dissolution; and with the consequences of economic growth for public pensions in Sweden. …

Buch. Condizione: Neu. Neuware - It is recognized that formal design and verification methods are an important requirement for the attainment of high quality system designs. The field has evolved enormously during the last few years, resulting in the fact that formal design and verification methods are nowadays supported by several tools, both commercial and academic. If different tools and users are to generate and read the same language then it is necessary that the same semantics is assigned by them to all constructs and elements of the language. The current IEEE standard VHDL language reference manual (LRM) tries to define VHDL as well as possible in a descriptive way, explaining the semantics in English. But rigor and clarity are very hard to maintain in a semantics defined in this way, and that has already given rise to many misconceptions and contradictory interpretations. Formal Semantics for VHDL is the first book that puts forward a cohesive set of semantics for the VHDL language. The chapters describe several semantics each based on a different underlying formalism: two of them use Petri nets as target language, and two of them higher order logic. Two use functional concepts, and finally another uses the concept of evolving algebras. Formal Semantics for VHDL is essential reading for researchers in formal methods and can be used as a text for an advanced course on the subject.…

Buch. Condizione: Neu. Neuware - The development of photosensitive materials in general and photoreactive polymers in particular is responsible for major advances in the information, imaging, and electronic industries. Computer parts manufacturing, information storage, and book and magazine publishing all depend on photoreactive polymer systems. The photo-and radiation-induced processes in polymers are also active areas of research. New information on the preparation and properties of com mercially available photosensitive systems is constantly being acquired. The recent demand for environmentally safe solvent-free and water-soluble materials also motivated changes in the composition of photopolymers and photoresists. The interest in holographic recording media for head-up displays, light scanners, and data recording stimulated development of reconfigurable and visible light sensitive materials. Photoconductive polymerizable coatings are being tested in electrostatic proofing and color printing. The list of available initiators, poly meric binders, and other coating ingredients is continually evolving to respond to the requirements of low component loss (low diffusivity) and the high rate of photochemical reactions.…

Buch. Condizione: Neu. Neuware - The Office of Health and Environmental Research (OHER) has supported and continues to support development of computational approaches in biology and medicine. OHER's Radiological and Chemical Physics Program initiated development of computational approaches to determine the effects produced by radiation of different quality (such as high energy electrons, protons, helium and other heavy ions, etc. ) in a variety of materials of biological interest-such as water, polymers and DNA; these include molecular excitations and sub-excitations and the production of ionization and their spatial and temporal distribution. In the past several years, significant advances have been made in computational methods for this purpose. In particular, codes based on Monte Carlo techniques have been developed that provide a realistic description of track-structure produced by charged particles. In addition, the codes have become sufficiently sophisticated so that it is now possible to calculate the spatial and temporal distribution of energy deposition patterns in small volumes of subnanometer and nanometer dimensions. These dimensions or resolution levels are relevant for our understanding of mechanisms at the molecular level by which radiations affect biological systems. Since the Monte Carlo track structure codes for use in radiation chemistry and radiation biology are still in the developmental stage, a number of investigators have been exploring different strategies for improving these codes.…

Buch. Condizione: Neu. Neuware - Deryn Watson and David Tinsley The topic of the conference, integrating infonnation technology into education, is both broad and multi-facetted. In order to help focus the papers and discussion we identified 7 themes: - Current developments in society and education influencing integration; - Teachers, their roles and concerns; - Learners, their expectations of and behaviour in an integrated environment; - Developments and concerns in the curriculum; - Successes and failures in existing practice; - Organisation and management of integrated environments; - Identification of social and political influences. Each author was invited to focus on one theme, and these remained strands throughout as can be seen from the short papers and focus group reports. The first and most significant concern therefore was to be clear about our notions of integration; what do we mean and how is this relevant Our keynote paper from Cornu clearly marked out this debate by examining the notion of integration and alerting us to the fact that as long as the use of IT is still added to the curriculum, then integration has not yet begun.…

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The ideas of probability are all around us. Lotteries, casino gambling, the al most non-stop polling which seems to mold public policy more and more these are a few of the areas where principles of probability impinge in a direct way on the lives and fortunes of the general public. At a more re moved level there is modern science which uses probability and its offshoots like statistics and the theory of random processes to build mathematical descriptions of the real world. In fact, twentieth-century physics, in embrac ing quantum mechanics, has a world view that is at its core probabilistic in nature, contrary to the deterministic one of classical physics. In addition to all this muscular evidence of the importance of probability ideas it should also be said that probability can be lots of fun. It is a subject where you can start thinking about amusing, interesting, and often difficult problems with very little mathematical background. In this book, I wanted to introduce a reader with at least a fairly decent mathematical background in elementary algebra to this world of probabil ity, to the way of thinking typical of probability, and the kinds of problems to which probability can be applied. I have used examples from a wide variety of fields to motivate the discussion of concepts. 268 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The Seven Countries Study has made central contributions to the under standing of the socio-cultural influences on population rates of cardiovascular diseases (CVD). It has pointed the way to preventive strategies for whole populations. The Study is unique as a long-term investigation, now in its 35th year. This pioneering work arose in part from a meeting between Professors Ancel Keys and Noboru Kimura to discuss differences observed in clinical mani festations and pathology of coronary disease in the U.S. and Japan. Professor Keys started explorations of the importance in these differences of dietary fat and serum cholesterol when he visited Japan in 1954, and thereafter initiated the Seven Countries Study to test these hypotheses. In the Japanese cohorts of the Study, it became evident from the outset that coronary artery disease was extremely rare, but its incidence has since increased along with dramatic lifestyle changes from traditional Japanese to western styles. The Japanese experience contrasts with a reduction in coronary artery disease in many western countries along with establishment of major preventive efforts in risk factor reduction and cardiac care. 256 pp. Englisch.…

Buch. Condizione: Neu.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Each year there are improvements in safety-critical system technology. These arise both from developments in the contributing technologies, such as safety engineering, software engineering, human factors and risk assessment, and from the adoption or adaptation of appropriate techniques from other domains, such as security. For these improvements to be of real benefit, they need to be applied during the appropriate stage in the life cycle of the system, whether it be development, assessment, or operation. For this to occur, they must be communicated and explained. Each year the Safety-critical Systems Symposium offers a distinguished forum for the presentation of papers on such developments, and also for papers from industry on the lessons learned from the use of technologies and methods. The results of many collaborative research projects, with components from both industry and academia, are reported in a universally understandable form. In 1995 the Symposium was held in Brighton, a venue calculated to stimulate not just the presenters of papers, but all the delegates. Yet, this book of Proceedings is intended not only for the delegates but also for readers not able to attend the event itself. We welcome both categories of reader. Delegates have the benefit of attending the presentations and the opportunity to participate in the discussions; those who take up this book after the event can peruse it attheir leisure and, perhaps, on account of it will resolve to attend subsequent symposia. 340 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -One can observe that a wide range of human activities involves various forms of de sign. Especially if the goal implies the creation of an artifact, design is at the very center of these activities. It is the general understanding in the public to place design especially in the context of, for example, fashion, furniture, household items, cars, and architecture or in a more general way at the intersection of art and engineering. Of course, in the field of information technology, developers of software and hard ware are called system 'designers'. Design can be identified and considered in the context of many activities related to pUblishing: creating a product ad in a magazine, designing the layout of a newspaper, authoring a book. Summarizing these exam ples as 'creating documents', these are activities where two challenges with respect to design have to be met. Designing the content, its structure, and its relationship to the existing knowledge of potential readers is one, while the other refers to the 'rhetorical' aspects including designing the presentation of the material in order to communicate the content. Publishing is communicating knowledge. 264 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The Translator's Workbench Project was a European Community sponsored research and development project which dealt with issues in multi-lingual communication and docu mentation. This book presents an integrated toolset as a solution to problems in translation and docu mentation. Professional translators and teachers of translation were involved in the proc ess of software development, starting with a detailed study of the user requirements and ending with several evaluation-and-improvement cycles of the resulting toolset. English, German, Greek, and Spanish are addressed in the contributions, however, some of the techniques are inherently language-independent and can thus be extended to cover other languages as well. Translation can be viewed broadly as the execution of three cognitive processes, and this book has been structured along these lines: - First, the translation pre-process, understanding the target language text at a lexico semantic level on the one hand, and making sense of the source language document on the other hand. The tools for the pre-translation process include access to electronic networks, conversion of documents from one format to another, creation of terminol ogy data banks and access to existing data banks, and terminology dictionaries. - Second, the translation process, rendering sentences in the source language into equiva lent target sentences. The translation process refers to the potential of conventional machine translation systems, like METAL, and of the statistically oriented translation memory. 196 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Given a mathematical structure, one of the basic associated mathematical objects is its automorphism group. The object of this book is to give a biased account of automorphism groups of differential geometric struc tures. All geometric structures are not created equal; some are creations of ~ods while others are products of lesser human minds. Amongst the former, Riemannian and complex structures stand out for their beauty and wealth. A major portion of this book is therefore devoted to these two structures. Chapter I describes a general theory of automorphisms of geometric structures with emphasis on the question of when the automorphism group can be given a Lie group structure. Basic theorems in this regard are presented in 3, 4 and 5. The concept of G-structure or that of pseudo-group structure enables us to treat most of the interesting geo metric structures in a unified manner. In 8, we sketch the relationship between the two concepts. Chapter I is so arranged that the reader who is primarily interested in Riemannian, complex, conformal and projective structures can skip 5, 6, 7 and 8. This chapter is partly based on lec tures I gave in Tokyo and Berkeley in 1965. 196 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The present book represents to a large extent the translation of the German 'Vorlesungen über Himmelsmechanik' by C. L. Siegel. The demand for a new edition and for an English translation gave rise to the present volume which, however, goes beyond a mere translation. To take account of recent work in this field a number of sections have been added, especially in the third chapter which deals with the stability theory. Still, it has not been attempted to give a complete presentation of the subject, and the basic prganization of Siegel's original book has not been altered. The emphasis lies in the development of results and analytic methods which are based on the ideas of H. Poincare, G. D. Birkhoff, A. Liapunov and, as far as Chapter I is concerned, on the work of K. F. Sundman and C. L. Siegel. In recent years the measure-theoretical aspects of mechanics have been revitalized and have led to new results which will not be discussed here. In this connection we refer, in particular, to the interesting book by V. I. Arnold and A. Avez on 'Problemes Ergodiques de la Mecanique Classique', which stresses the interaction of ergodic theory and mechanics. We list the points in which the present book differs from the German text. In the first chapter two sections on the tri pie collision in the three body problem have been added by C. L. Siegel. 308 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In presenting this treatment of homological algebra, it is a pleasure to acknowledge the help and encouragement which I have had from all sides. Homological algebra arose from many sources in algebra and topology. Decisive examples came from the study of group extensions and their factor sets, a subject I learned in joint work with OTTO SCHIL LING. A further development of homological ideas, with a view to their topological applications, came in my long collaboration with SAMUEL ElLENBERG; to both collaborators, especial thanks. For many years the Air Force Office of Scientific Research supported my research projects on various subjects now summarized here; it is a pleasure to acknowledge their lively understanding of basic science. Both REINHOLD BAER and JOSEF SCHMID read and commented on my entire manuscript; their advice has led to many improvements. ANDERS KOCK and JACQUES RIGUET have read the entire galley proof and caught many slips and obscurities. Among the others whose sug gestions have served me well, I note FRANK ADAMS, LOUIS AUSLANDER, WILFRED COCKCROFT, ALBRECHT DOLD, GEOFFREY HORROCKS, FRIED RICH KASCH, JOHANN LEICHT, ARUNAS LIULEVICIUS, JOHN MOORE, DIE TER PUPPE, JOSEPH YAO, and a number of my current students at the University of Chicago - not to m~ntion the auditors of my lectures at Chicago, Heidelberg, Bonn, Frankfurt, and Aarhus.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In recent years new topological methods, especially the theory of sheaves founded by J. LERAY, have been applied successfully to algebraic geometry and to the theory of functions of several complex variables. H. CARTAN and J. -P. SERRE have shown how fundamental theorems on holomorphically complete manifolds (STEIN manifolds) can be for mulated in terms of sheaf theory. These theorems imply many facts of function theory because the domains of holomorphy are holomorphically complete. They can also be applied to algebraic geometry because the complement of a hyperplane section of an algebraic manifold is holo morphically complete. J. -P. SERRE has obtained important results on algebraic manifolds by these and other methods. Recently many of his results have been proved for algebraic varieties defined over a field of arbitrary characteristic. K. KODAIRA and D. C. SPENCER have also applied sheaf theory to algebraic geometry with great success. Their methods differ from those of SERRE in that they use techniques from differential geometry (harmonic integrals etc. ) but do not make any use of the theory of STEIN manifolds. M. F. ATIYAH and W. V. D. HODGE have dealt successfully with problems on integrals of the second kind on algebraic manifolds with the help of sheaf theory. I was able to work together with K. KODAIRA and D. C. SPENCER during a stay at the Institute for Advanced Study at Princeton from 1952 to 1954. 252 pp. Englisch.…
