Buch. Condizione: Neu. Neuware - This monograph contains 20 selected papers presented at the Symposium on Subcellular Basis of Contractile Failure which was held in Ottawa during May 11-13, 1989 and is designed for the benefit ofthose who were unable to attend this event. It is now increasingly becoming clear that an excessive amount of calcium is intimately involved in the pathogenesis of a wide variety of heart diseases. Accordingly, the investigations concerning the role of calcium chan nels and their regulatory mechanisms in heart function as well as of the intra cellular calcium overload in cardiac dysfunction are presented here. Since sodium is also considered to influence the cardiac contractile force by chang 2 ing the intracellular concentration of calcium through the Na +-Ca+ exchange 2 mechanism in the cell membrane, the role of Na +-Ca+ exchange in heart func tion as well as pathology of contractile failure is discussed. In view of the new ly discovered implications of the oxygen free radicals in cellular injury, papers concerning the role of these radicals in heart disease are included in this book. For the purpose of clarity, different chapters have been organized under three main headings: (I) Role of cations in heart function, (II) Cardiac hypertrophy and cardiomyopathies, and (III) Ischemic heart disease and cardiac failure.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This research monograph provides a self-contained approach to the problem of determining the conditions under which a compact bordered Klein surface S and a finite group G exist, such that G acts as a group of automorphisms in S. The cases dealt with here take G cyclic, abelian, nilpotent or supersoluble and S hyperelliptic or with connected boundary. No advanced knowledge of group theory or hyperbolic geometry is required and three introductory chapters provide as much background as necessary on non-euclidean crystallographic groups. The graduate reader thus finds here an easy access to current research in this area as well as several new results obtained by means of the same unified approach. 228 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This book contains a selection of the lectures presented at the Euromech Colloquium 255, held at the Liborianum, Paderborn, from 31 October to 2 November 1989. The subject of the Colloquium 'Thermal Effects in Fracture of Multiphase Materials' attracted about 50 scientists from 13 coun tries. Several well known scientists who are active in research on thermal effects in fracture proces ses were present at the Colloquium as lecturers (29 lectures were delivered) as well as valuable participants of the intensive discussions which took part during the sessions, coffe breaks and lunch times. The closing session of the Colloquium was devoted to a general discussion on the trends in the development of the research in the field, the prospects of the theoretical research, new materials (composites, ceramics etc. ), and the trends in technological applications. Over twenty comments and remarks have been made during this final general discussion, showing the interest of the audi torium in such an exchange of viewpoints. However, this discussion is not reflected in this volume. The Colloquium has been subdivided into six sessions: I 'Thermodynamics of Fracture Processes' II . 'Fracture of Nonhomogeneous Solids' III 'Thermal Cracking of Heterogeneous Materials' IV-VI 'Fracture Phenomena in Composite Systems I-III' One of the main topics in session I consisted in the description of the influence of thermal effects on shear band localization failure. Thereby shear bands nucleate due. 260 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Parallelism or concurrency is one of the fundamental concepts in computer science. But in spite of its importance, theoretical methods to handle concurrency are not yet sufficiently developed. This volume presents a comprehensive study of Mazurkiewicz' trace theory from an algebraic-combinatorial point of view. This theory is recognized as an important tool for a rigorous mathematical treatment of concurrent systems. The volume covers several different research areas, and contains not only known results but also various new results published nowhere else. Chapter 1 introduces basic concepts. Chapter 2 gives a straight path to Ochmanski's characterization of recognizable trace languages and to Zielonka's theory of asynchronous automata. Chapter 3 applies the theory of traces to Petri nets. A kind of morphism between nets is introduced which generalizes the concept of synchronization. Chapter 4 provides a new bridge between the theory of string rewriting and formal power series. Chapter 5 is an introduction to a combinatorial theory of rewriting on traces which can be used as an abstract calculus for transforming concurrent processes. 184 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In the decade since the first edition of this book was published advances have been made in our knowledge of the fresh waters of the world, espe cially in understanding many of the processes involved in their functioning as systems and in countering the problems created by human activities. New problems too, many of an international nature, have loomed during this period-of which global warming and the acidification of fresh waters in many parts of the world are notable examples. In addition, much has now been published concerning the aquatic flora, fauna and ecology of previously poorly known geographic areas, notably Australasia. The second edition of this book is a revision which updates the text in the light of recent advances in our knowledge of freshwater biology. Inevitably, in an elementary volume such as this, the treatment of many of the basic principles and processes remains the same. However, several new sections are included covering a range of topics such as acid deposition and the acidification process, bacterial decomposition and aquaculture. The book includes many new references and suggestions for up-to-date reading in particular topics. The objective of the second edition remains the same as that of the first. It is intended as a basic introduction to the major aspects of freshwater biology at a level suitable for undergraduates. It should also prove useful, as apparently did the first edition, to professional workers in related fields, e.g. water engineers and chemists, aquaculturists and planners. 292 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This is a translation - with some new material - of a seminal contribution to the debate about the design of tomorrow's factories in the light of advancing computer and control technology. Peter Brödner contrasts mass production with workshop production and challenges the assertion that modern production systems create multi-faceted and responsible tasks requiring correspondingly intense training. He analyses the impact of automation on intellectual work and knowledge-based systems. Is the 'workerless factory' possible, or even desirable Can we avoid the future shown in Lang's Metropolis Can computers really be made to help rather than replace the workforce Peter Brödner succeeds in transforming a sociological critical study and economic analysis into a series of convincing technological proposals, based on his thorough understanding of production technologies gained whilst working at the Production Engineering Centre in Karlsruhe. The book was originally published in German under the title Fabrik 2000. Eine kritische soziologische Studie und ökonomische Analyse moderner Produktionsmethoden führen zu einer Reihe überzeugender technologischer Vorschläge. Die deutsche Originalfassung dieses Buches hat den Titel Fabrik 2000. 148 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In this book interrelated factor demand models are surveyed. New methods are developed and are analysed empirically using Dutch and U.K. time series data. New methods are discussed for obtaining closed form solutions of linear ratinal expectations models, providing deeper insights into the identification of structural parameters of underlying theoretical models; recently developed time series techniques are applied in order to estimate structural parameters and test for model specification, stationarity and stability through time; new models are developed in which the rather stringent and questionable restrictions of symmetry generally imposed upon stochastic adjustment models of labour demand are relaxed, the models are analysed empirically using time series data of Dutch and U.K. manufacturing production and nonproduction workers. 172 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The European Communications Policy Research Conference has taken place the fourth time since its founding in 1986. The main objective of all conferences held so far was to be a forum where social scientists, economists, engineers as well as lawyers come together to debate about current research in the field of European communications policy. The last three conferences were organized by the Centre for Communication and Information Studies (CCIS) in London and its director Nicholas Garnham. At the 1988 Conference all participants agreed that the conference should have a future and that in particular the original ambition of the conference should be realized more fully by making it a truly European event. In the meantime, it has been proven to be possible to host the conference on a circulating yearly basis in various European countries. The Organizing Committee for this year's conference contained members from The Netherlands, France, UK and West-Germany. This year's conference was hosted and organized by WIK and held in Kronberg, West-Germany. 340 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Attribute grammars were introduced over twenty years ago, but they are still not as widely used as could have been hoped initially. This is particularly so in industry, despite their qualities as a specification tool. The aim of this International Workshop on Attribute Grammars and their Applications (WAGA), the first to be entirely devoted to this topic, was to show that they are still the subject of active research and now lead to important, useful and practical applications in various areas. The workshop covered all aspects of attribute grammars, with an emphasis on practical results. This volume includes the text of the three invited talks and 21 submitted papers presented at the workshop. This selection provides a wide view of the diverse research being done in the area. Topics include: - Fundamentals: efficient exhaustive and incremental at- tribute evaluation methods, parallel evaluation, space optimization, relationships with functional, logic and object-oriented programming, and systems. - Applications: compiler construction, natural language processing, and interactive program manipulation. 372 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Functional analysis has become a sufficiently large area of mathematics that it is possible to find two research mathematicians, both of whom call themselves functional analysts, who have great difficulty understanding the work of the other. The common thread is the existence of a linear space with a topology or two (or more). Here the paths diverge in the choice of how that topology is defined and in whether to study the geometry of the linear space, or the linear operators on the space, or both. In this book I have tried to follow the common thread rather than any special topic. I have included some topics that a few years ago might have been thought of as specialized but which impress me as interesting and basic. Near the end of this work I gave into my natural temptation and included some operator theory that, though basic for operator theory, might be considered specialized by some functional analysts. 424 pp. Englisch.
