Buch. Condizione: Neu. Neuware - This volume in the series Developments in Medical Virology deals with viruses involved in diabetes mellitus, a syndrome with a strong genetic background that causes damage to the regulation of insulin synthesis and function. Viruses were found either to cause or to stimulate diabetes mellitus in man and in animal models. The nature of the role of viruses is described by many of the scientists who participated in the original studies. To complete the picture, chapters were included that deal with the insulin gene, the secondary structure of the proinsulin and insulin receptor polypeptides, pancreatic Langerhans islets, and clinical considerations of the disease. The aim of Developments in Medical Virology is to elucidate processes involving viruses as pathogens of cells and organisms, with special attention to human diseases. A number of volumes will be devoted to viruses affecting specific organs (e.g. brain, liver, etc.), while others will elaborate on the clinical experience in the use of antiviral drugs. The series is published in parallel with Developments in Molecular Virology, designed to present an analysis of molecular mechanisms implicated in virus infection and replicative processes. In addition, the series Developments in Veterinary Virology provides information on viruses causing diseases in animals, with special emphasis on aspects of interest to veterinarians.

Buch. Condizione: Neu. Neuware - Frederick Burwick's modest but comprehensive and insightful intro duction is preface enough to these sensible essays in the history and philosophical criticism of ideas. If we want to understand how some in quiring and intelligent thinkers sought to go beyond mechanism and vitalism, we will find Burwick's labors of assembling others and reflect ing on his own part to be as stimulating as anywhere to be found. And yet his initial cautious remark is right: 'approaches', not 'attainments'. The problems associated with clarifying 'matter' and 'form' are still beyond any consensus as to their solution. Even more do we recognize the many forms and meanings of 'form', and this is so even for 'organic form'. That wise scientist-philosopher-engineer Lancelot Law Whyte struggled in a place neighboring to Burwick's, and his essay of thirty years ago might be a scientist's preface to Burwick and his colleagues: see Whyte'S Accent on Form (N. Y., Harper, 1954) and his Symposium of 1951 Aspects of Form (London, Percy Lund Humphries 1951; and Indiana University Press 1961), itself arranged in honor of D' Arcy Thompson's classical monograph On Growth and Form. Philosophy and history of science must deal with these issues, and with the mixture of hard-headedness and imagination that they de mand.

Buch. Condizione: Neu. Neuware - This volume has its origin in the third Workshop on Maximum-Entropy and Bayesian Methods in Applied Statistics, held at the University of Wyoming, August 1 to 4, 1983. It was anticipated that the proceedings of this workshop could not be prepared in a timely fashion, so most of the papers were not collected until a year or so ago. Because most of the papers are in the nature of advancing theory or solving specific problems, as opposed to status reports, it is believed that the contents of this volume will be of lasting interest to the Bayesian community. The workshop was organized to bring together researchers from differ ent fields to examine critically maximum-entropy and Bayesian methods in science, engineering, medicine, economics, and other disciplines. Some of the papers were chosen specifically to kindle interest in new areas that may offer new tools or insight to the reader or to stimulate work on pressing problems that appear to be ideally suited to the maximum-entropy or Bayes ian method.

Buch. Condizione: Neu. Neuware - As a clinical discipline blood transfusion encompasses enormous vista, vary ing from biotechnology to molecular biology, from plasma products, cell biology and growth factors to interleukines. Growth of knowledge in this field has been rapid, and expertise is now required to be mastered and renewed in translating these ideas for patient care. Various types of cells could be harvested - progenitor stem cells derived from bone marrow or from circulating blood as a source for transplants; in the hemostatic armoury platelets could be used prophylactically; granulocytes and mononuclear cells are available for treatment of infections or immune modulations. However, their therapeutic use carries potential complications including graft versus host disease and CMV-infection. Prevention of such complications by irradiation and by removal of immunocompetent leukocytes are important issues. Thus, production of such therapeutic materials ought to address the issues at the earliest, to eliminate those problems while adhering to the con cept of high quality; the impact of storing platelets for longer periods by using improved plastic containers or storing almost indefinitely in frozen state should be explored. Rapid progress in cell culture techniques and bio technology have enriched the transfusion medicine armoury with lympho kines, interferons and cell colony growth factors which have great potentials for enhancement of basic knowledge as well as considerable therapeutic applications in patients.

Buch. Condizione: Neu. Neuware - A HISTORY OF MALIGNANT HYPERTHERMIA Malignant hyperthermia (MH) is a hereditary disorder of muscle. Undoubtedly, individuals have possessed this trait since time immemorial. However, because the trait is usually only unmasked in the presence of potent inhalational anaesthetic agents or non-depolarizing skeletal muscle relaxants, the existence of malignant hyperthermia was not suspected until we' after the dawn of the modern anaesthetic era. In the early years of ether and chloroform anaesthesia, monitoring was minimal. Body temperature was never measured. A finger on the pulse, and observation of respirations and skin colour were the most that could be expected. Death was not infrequent and usually unexplained (1). By the beginning of the twentieth century, reports of fulminant fever and tachycardia (rapid heart rate) during or immediately after anaesthesia often ending in death, were being described with increasing frequency in the medical literature (2-6). As a number of cases from New York had occurred during summer months, they were initially thought to be a form of heat stroke due to overly hot operating theatres (2-6). However, one enterprising anaesthetist (5:' checked the weather reports for the days on which some of these so called 'heat strokes' had occurred. He found that on the days i'n question the ambient 0 temperature had never been in excess of 72 F. Environmental heat, therefore, could not have been a cause of at least some of these reactions.

Buch. Condizione: Neu. Neuware - By definition Biomechanics is the application of engineering methods to study the mechanical aspects of living beings. Mostly the life scientists have the questions but lack of the specialized methods. The engineers on the other hand can handle very specialized equipment and methods, but lack in the biological thinking. If both sides are able to adapt to each other, Biomechanics is a classical field of interdis ciplinary cooperation. In the beginning, most biomechanical research was done in the field of orthopaedics. But other areas like cardiovascular research, dentistry, sports and many others gain increasing importance. This situation is clearly reflected in this book, which contains a selected number of papers which were presented at the Fifth Meeting of the European Society of Biomechanics, held in September 1986 in Berlin. Meanwhile these meetings have become a well accepted forum and a place of interdis ciplinary discussion for scientists in Biomechanics on the one side and surgeons and other peoples interested in biome chanical solutions on the other. It is the third time that the proceedings are published as a book and the editors are sure that this volume will help to establish this series 'Developement in Biomechanics' as a valuable tool for all people involved in Biomechanics. The Fifth Meeting of the ESB also marks the tenth anniversary in the short history of the European Society of Biomechanics.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Grids are special families of tripotents in Jordan triple systems. This research monograph presents a theory of grids including their classification and coordinization of their cover. Among the applications given are - classification of simple Jordan triple systems covered by a grid, reproving and extending most of the known classification theorems for Jordan algebras and Jordan pairs - a Jordan-theoretic interpretation of the geometry of the 27 lines on a cubic surface - structure theories for Hilbert-triples and JBW\*-triples, the Jordan analogues of Hilbert-triples and W\*-algebras which describe certain symmetric Banach manifolds. The notes are essentially self-contained and independent of the structure theory of Jordan algebras and Jordan pairs. They can be read by anyone with a basic knowledge in algebraic geometry or functional analysis. The book is intended to serve both as a reference for researchers in Jordan theory and as an introductory textbook for newcomers to the subject. 208 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Classification of commuting non-selfadjoint operators is one of the most challenging problems in operator theory even in the finite-dimensional case. The spectral analysis of dissipative operators has led to a series of deep results in the framework of unitary dilations and characteristic operator functions. It has turned out that the theory has to be based on analytic functions on algebraic manifolds and not on functions of several independent variables as was previously believed. This follows from the generalized Cayley-Hamilton Theorem, due to M.S.Livsic: 'Two commuting operators with finite dimensional imaginary parts are connected in the generic case, by a certain algebraic equation whose degree does not exceed the dimension of the sum of the ranges of imaginary parts.' Such investigations have been carried out in two directions. One of them, presented by L.L.Waksman, is related to semigroups of projections of multiplication operators on Riemann surfaces. Another direction, which is presented here by M.S.Livsic is based on operator colligations and collective motions of systems. Every given wave equation can be obtained as an external manifestation of collective motions. The algebraic equation mentioned above is the corresponding dispersion law of the input-output waves. 120 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This monograph is concerned with the equilibrium of linearly elastic cylinders. It gives an up-to-date and systematic treatment of extension, bending, torsion and flexure of cylinders, including the deformation of homogeneous and nonhomogeneous anisotropic elastic cylinders by loads distributed on their lateral surfaces. Minimum energy characterizations of the solutions are discussed. An analysis of Saint-Venant's principle, in the context for which it was originally intended, is also presented. Many of the results included have not appeared or been previously discussed in the literature, and illustrative applications are presented throughout. 172 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -It is well known that there are close relations between classes of singularities and representation theory via the McKay correspondence and between representation theory and vector bundles on projective spaces via the Bernstein-Gelfand-Gelfand construction. These relations however cannot be considered to be either completely understood or fully exploited. These proceedings document recent developments in the area. The questions and methods of representation theory have applications to singularities and to vector bundles. Representation theory itself, which had primarily developed its methods for Artinian algebras, starts to investigate algebras of higher dimension partly because of these applications. Future research in representation theory may be spurred by the classification of singularities and the highly developed theory of moduli for vector bundles. The volume contains 3 survey articles on the 3 main topics mentioned, stressing their interrelationships, as well as original research papers. 400 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The past several years have witnessed a striking number of important developments in Complex Analysis. One of the characteristics of these developments has been to bridge the gap existing between the theory of functions of one and of several complex variables. The Special Year in Complex Analysis at the University of Maryland, and these proceedings, were conceived as a forum where these new developments could be presented and where specialists in different areas of complex analysis could exchange ideas. These proceedings contain both surveys of different subjects covered during the year as well as many new results and insights. The manuscripts are accessible not only to specialists but to a broader audience. Among the subjects touched upon are Nevanlinna theory in one and several variables, interpolation problems in Cn, estimations and integral representations of the solutions of the Cauchy-Riemann equations, the complex Monge-Ampère equation, geometric problems in complex analysis in Cn, applications of complex analysis to harmonic analysis, partial differential equations. 348 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In October 1983 an informal meeting was organized in Le Cap d'Agde with the help of the BIGRE bulletin. Sixty people turned out to hear more than ten presentations on object-oriented programming. More important was their unanimous demand for other, more structured encounters. So, about one year later, the Object group was created by AFCET. A second workshop was organized in Brest, and again one year later in Paris, each time showing increased attendance and interest. The success of these meetings and the fact that similar activities were taking place in other European countries, especially Great Britain and Germany, led to the idea of an annual European Conference, providing a forum for theorists and practitioners interested in the object-oriented programming paradigm. It is impossible to acknowledge here all the people and organizations that welcomed with great enthusiasm the birth of the ECOOP conference and contributed to its organization. More than a hundred submissions were received and the program committee had the unpleasant task of turning down many valuable contributions. We hope, however, that the selection of papers for ECOOP'87 emphasizes the fundamental issues and problems of object-oriented programming and will point toward interesting future research directions. 284 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Freeness of an action of a compact Lie group on a compact Hausdorff space is equivalent to a simple condition on the corresponding equivariant K-theory. This fact can be regarded as a theorem on actions on a commutative C\*-algebra, namely the algebra of continuous complex-valued functions on the space. The successes of 'noncommutative topology' suggest that one should try to generalize this result to actions on arbitrary C\*-algebras. Lacking an appropriate definition of a free action on a C\*-algebra, one is led instead to the study of actions satisfying conditions on equivariant K-theory - in the cases of spaces, simply freeness. The first third of this book is a detailed exposition of equivariant K-theory and KK-theory, assuming only a general knowledge of C\*-algebras and some ordinary K-theory. It continues with the author's research on K-theoretic freeness of actions. It is shown that many properties of freeness generalize, while others do not, and that certain forms of K-theoretic freeness are related to other noncommutative measures of freeness, such as the Connes spectrum. The implications of K-theoretic freeness for actions on type I and AF algebras are also examined, and in these cases K-theoretic freeness is characterized analytically. 380 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -With characteristic incisiveness Georg Henrik von Wright identifies pro haireticIogic (i. e. the logic of preference) as the core of a general theory of value concepts. Essentially, this nucleus involves the logical study of acts from the point of view of their preferability. 1 (italics added) Though the term prohairesis is found in Plato, as well as in Aristotle's treatment of the relations of preference, it is von Wright who introduces this word into contemporary analytical philoso phy, and succinctly specifies the philosophical dimensions it encompasses. The above emphasis upon the philosophical study of the formalization of preferences is a matter of utmost importance for understanding the type of in quiry this investigation attempts to initiate. Over the past one hundred years the literature on general theories of subjective utility has become massive, where one considers the work done in psychometrics, econometrics, statistical theories, probability theories, etc., etc. Histories in these areas are strong in tracing various evolutions in the development of the concept of preference in decision-making. However, what has not been investigated with sustained at tention are the fundamentally philosophical inquiries into the formalization of preference-relations. 300 pp. Englisch.

The term was used for the first time in the New York World, March 1920, to describe 'new statistical machines with the mental power of 100 skilled mathematicians in solving even highly complex algebraic problems. ' Invented by Mendenhall and Warren, these machines were used at Columbia University'S Statistical Bureau. Recently, supercomputers have been used primarily to solve large-scale prob lems in science and engineering. Solutions of systems of partial differential equa tions, such as those found in nuclear physics, meteorology, and computational fluid dynamics, account for the majority of supercomputer use today. The early computers, such as EDVAC, SSEC, 701, and UNIVAC, demonstrated the feasibility of building fast electronic computing machines which could become commercial products. The next generation of computers focused on attaining the highest possible computational speeds. This book discusses the architectural approaches used to yield significantly higher computing speeds while preserving the conventional, von Neumann, machine organization (Chapters 2-4). Subsequent improvements depended on developing a new generation of computers employing a new model of computation: single-instruction multiple data (SIMD) processors (Chapters 5-7). Later machines refmed SIMD architec ture and technology (Chapters 8-9). SUPERCOMPUTER ARCHITECI'URE CHAPTER! INTRODUCTION THREE ERAS OF SUPERCOMPUTERS Supercomputers -- the largest and fastest computers available at any point in time -- have been the products of complex interplay among technological, architectural, and algorithmic developments. 216 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Respiratory Disease, the latest volume in the 'Treatment in Clinical Medicine' series, is in two parts: the first reviews the background to each of the main respiratory diseases with particular emphasis on management and treatment. The second reviews the main drugs used in respiratory practice in more detail and combines a pharmacological appraisal with a more personal assessment of their role and value in treatment. Practical aspects of management are emphasised. Where uncertainty exists the authors have described their own practice. The book aims to fill the gap which exists between textbooks of respiratory medicine, where there is often insufficient space to cover treatment in detail, and pharmacological textbooks, which are not concerned with practical management problems. It is intended for respiratory physicians, general physicians and senior medical students, and will provide useful background information for researchers entering the the field. 300 pp. Englisch.

There were 150 participants from 19 countries. This was the first IAU Symposium devoted exclusively to elliptical galaxies. The last decade has been a period of exceptionally rapid progress regard ing our understanding of elliptical galaxies, driven on the observational side by a wealth of new photometric and spectroscopic data, and on the theoretical side by the recognition that ellipticals are slowly rotating triaxial systems, instead of rotationally flattened bodies. The 30 invited speakers reviewed all aspects of this progress, its consequences, and the major outstanding problems. Nearly 80 poster contributions were displayed for the duration of the meeting. These contained many of the most recent developments. The first part of these Proceedings contains the written versions of the invited reviews and the summary, in the order of their presentation. The accompanying discussions are based on the written versions of questions and answers as handed in by the participants. The second part of this book is devoted to the poster contribu tions. They have been grouped in a thematic order, proceeding from morphology to theory. Indices of objects, subjects, and names are provided. Unfortunately, none of the invited participants from the USSR were able to attend the Symposium.

This item is printed on demand - it takes 3-4 days longer - Neuware -The ener~y crisis in 1973 and 1979 initiated a great number of activities and programs for low and high temperature applica tion of solar energy. Synthetic fuels and chemicals produced by solar energy is one of them, where temperatures in the range of 600-1000°C or even higher are needed. In principle such high temperatures can be produced in solar towers. For electricity tower plants production, the feasibility and operation of solar Solar Power has been examined during the SSPS - project (Small System) in Almeria, Spain. extend The objective of Solar Thermal Energy Utilization is to field the experience from the former SSPS - program in to the of solar produced synthetic fuels. New materials and technolo gies have to be developed in order to research this goal. Metallic components now in use for solar receivers need to be improved with respect to transient operation or possibly replaced by ceramics. High temperature processes, like steam-methane reforming, coal conversion and hydrogen produc tion need to be developed or at least adapted for the unconven tional solar operation. Therefore Solar Thermal Energy Utiliza tion is a long term program, which needs time for its develop ment much more time than the intervals expected in between further energy crisis. The 'Studies on Technology and Applica tion on Solar Energy Utilization' is a necessary step in the right direction in order to prepare for the energy problems in the future. 312 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Since the beginning of the fifties, the ruling paradigm in the discipline of economics has been that of a competitive general equilibrium. Associated dynamic analyses have therefore been preoccupied with the stability of this equilibrium state, corresponding simply to studies of comparative statics. The need to permeate the boundaries of this paradigm in order to open up new pathways for genuine dynamic analysis is now pressing. The contributions contained in this volume spring from this very ambition. A growing circle of economists have recently been inspired by two distinct but complementary sources: (i) the pathbreaking work of Joseph Schumpeter, and (ii) recent contributions to physics, chemistry and theoretical biology. It turns out that problems which are firmly rooted in the economic discipline, such as innovation, technological change, business cycles and economic development, contain many clear parallels with phenomena from the natural sciences such as the slaving principle, adiabatic elimination and self-organization. In such dynamic worlds, adjustment processes and adaptive behaviour are modelled with the aid of the mathematical theory of nonlinear dynamical systems. The dynamics is defined for a much wider set of conditions or states than simply a set of competitive equilibria. A common objective is to study and classify ways in which the qualitative properties of each system change as the parameters describing the system vary. 396 pp. Englisch.

This research monograph presents a theory of grids including their classification and coordinization of their cover. Among the applications given are - classification of simple Jordan triple systems covered by a grid, reproving and extending most of the known classification theorems for Jordan algebras and Jordan pairs - a Jordan-theoretic interpretation of the geometry of the 27 lines on a cubic surface - structure theories for Hilbert-triples and JBW\*-triples, the Jordan analogues of Hilbert-triples and W\*-algebras which describe certain symmetric Banach manifolds. The notes are essentially self-contained and independent of the structure theory of Jordan algebras and Jordan pairs. They can be read by anyone with a basic knowledge in algebraic geometry or functional analysis. The book is intended to serve both as a reference for researchers in Jordan theory and as an introductory textbook for newcomers to the subject.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 208 pp. Englisch.

Neuware -Classification of commuting non-selfadjoint operators is one of the most challenging problems in operator theory even in the finite-dimensional case. The spectral analysis of dissipative operators has led to a series of deep results in the framework of unitary dilations and characteristic operator functions. It has turned out that the theory has to be based on analytic functions on algebraic manifolds and not on functions of several independent variables as was previously believed. This follows from the generalized Cayley-Hamilton Theorem, due to M.S.Livsic: 'Two commuting operators with finite dimensional imaginary parts are connected in the generic case, by a certain algebraic equation whose degree does not exceed the dimension of the sum of the ranges of imaginary parts.' Such investigations have been carried out in two directions. One of them, presented by L.L.Waksman, is related to semigroups of projections of multiplication operators on Riemann surfaces. Another direction, which is presented here by M.S.Livsic is based on operator colligations and collective motions of systems. Every given wave equation can be obtained as an external manifestation of collective motions. The algebraic equation mentioned above is the corresponding dispersion law of the input-output waves.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 120 pp. Englisch.
