Taschenbuch. Condizione: Neu. Neuware - Imagine living during the Renaissance and being able to interview that era's greatest scientists about their inspirations, discoveries, and personal interests. The latter half of our century has seen its own Renaissance--informations technology has changed irrevocable the way we live, work, and think about the world. We are fortunate, therefore, that the authors of Out of Their Minds have been able to talk so candidly with the founders of computer science.

Taschenbuch. Condizione: Neu. Neuware -The book is devoted to the geometrical construction of the representations of Lusztig's small quantum groups at roots of unity. These representations are realized as some spaces of vanishing cycles of perverse sheaves over configuration spaces. As an application, the bundles of conformal blocks over the moduli spaces of curves are studied. The book is intended for specialists in group representations and algebraic geometry.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 300 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The time has now come when graph theory should be part of the education of every serious student of mathematics and computer science, both for its own sake and to enhance the appreciation of mathematics as a whole. This book is an in-depth account of graph theory, written with such a student in mind; it reflects the current state of the subject and emphasizes connections with other branches of pure mathematics. The volume grew out of the author's earlier book, Graph Theory -- An Introductory Course, but its length is well over twice that of its predecessor, allowing it to reveal many exciting new developments in the subject. Recognizing that graph theory is one of several courses competing for the attention of a student, the book contains extensive descriptive passages designed to convey the flavor of the subject and to arouse interest. In addition to a modern treatment of the classical areas of graph theory such as coloring, matching, extremal theory, and algebraic graph theory, the book presents a detailed account of newer topics, including Szemer'edi's Regularity Lemma and its use, Shelah's extension of the Hales-Jewett Theorem, the precise nature of the phase transition in a random graph process, the connection between electrical networks and random walks on graphs, and the Tutte polynomial and its cousins in knot theory. In no other branch of mathematics is it as vital to tackle and solve challenging exercises in order to master the subject. To this end, the book contains an unusually large number of well thought-out exercises: over 600 in total. Although some are straightforward, most of them are substantial, and others will stretch even the most able reader.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 412 pp. Englisch.

Buch. Condizione: Neu. Neuware -Over the last few years it has become apparent that fluid turbulence shares many common features with plasma turbulence, such as coherent structures and self-organization phenomena, passive scalar transport and anomalous diffusion. This book gathers very high level, current papers on these subjects. It is intended for scientists and researchers, lecturers and graduate students because of the review style of the papers.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 452 pp. Englisch.

Buch. Condizione: Neu. Neuware -This book proceeds from basic theory to design studies of concert and multiple purpose halls. The author introduces a remarkable seat selection system for analysis of new and existing halls and proposes a diagnostic system for testing physical properties and calculating psychological attributes at any seat after a hall is built. The book also presents a theory of subjective preferences, vbased on a model of the auitory cognitive system in the brain. Readers can thus follow the temporal and spatial values that may be associated with the left and right cerebral hemispheres in listening to music and speech, respectively, in a room. From results of calculating subjective preference at each seat, for example, architects, musicians, and acousticical engineers concerned with the design and use of concert and multi-use halls may determine the best location to perform a certain type of music on the stage, as well as the best seats from which to listen. These results will also allow designers tooptimize the height of the canopy above the stage, and the positions of other reflectors to fuse performer and hall sound. At the end of the book such a design theory is described, incorporating temporal and spatial values that may be generalized in physical environmental design. In writing this book, the author has paid special attention to stimulating the left and the right hemispheres of the brain with both text and illustrations. Written at the level of advanced undergraduate students, this book should be of interest not only to acoustical engineers and architects, but also to musicians, acoustical consultants, audio engineers, and sound coordinators of concert halls and theaters, as well as researchers who are interested in fusing science and art.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 272 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This book gathers together research from three key application themes of modelling in operational research - modelling to support evaluation and change in organisations; modelling within the development and use of organisational information systems; and the use of modelling approaches to support, enable and enhance decision support in organisational contexts. The issues raised provide valuable insight into the range of ways in which operational research techniques and practices are being successfully applied in today's information-centred business world. Modelling for Added Value provides a window onto current research and practise in modelling techniques and highlights their rising importance across the business, industrial and commercial sectors. The book contains contributions from a mix of academics and practitioners and covers a range of complex and diverse modelling issues, highlighting the broad appeal of this increasingly important subject area.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 256 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This book constitutes the refereed proceedings of the 9th Annual Symposium on Combinatorial Pattern Matching, CPM 98, held in Piscataway, NJ, USA, in July 1998. The 17 revised full papers presented were carefully reviewed and selected for inclusion in the book. The papers address all current issues in combinatorial pattern matching dealing with a variety of classical objects to be matched as well as with DNA coding.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 268 pp. Englisch.

Buch. Condizione: Neu. Neuware -My initial purpose in writing this book was to offer readers an update of my book Fetal Alcohol Syndrome and Fetal Alcohol Effects (Plenum, 1984), which con tained a broad overview of the history (actually the absence of any history) ofthe awareness of alcohol's teratogenic potential; a review of alcohol's pharmacology, especially with respect to pregnancy; a survey of the physical and behavioral effects of prenatal alcohol exposure; and an overview of the mechanisms sus pected of being responsible for those effects. I have omitted most of the previously examined historical and pharmacologi cal information because not much of what was previously discussed needed revision. On the other hand, because much more has been learned about the consequences of prenatal alcohol exposure and its potential mechanisms of action, I have considerably expanded my discussion of these topics. In doing so, I have attempted to include as much new material as possible without (I hope) being overly pedantic and thereby losing the proverbial forest for the trees. No book is ever entirely neutral in the topics it discusses, the issues it raises, or in its conclusions. In sifting through hundreds and oftentimes thousands of articles, writers have to choose which facts to emphasize and which to ignore. Every idea cannot be chronicled and every article cannot (and should not) be cited. In going about the business of picking and choosing, however, a writer has an obligation to present the arguments for and against a particular conclusion.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 276 pp. Englisch.

Buch. Condizione: Neu. Neuware -Self-organizing maps (SOM) have proven to be of significant economic value in the areas of finance, economic and marketing applications. As a result, this area is rapidly becoming a non-academic technology. This book looks at near state-of-the-art SOM applications in the above areas, and is a multi-authored volume, edited by Guido Deboeck, a leading exponent in the use of computational methods in financial and economic forecasting, and by the originator of SOM, Teuvo Kohonen. The book contains chapters on applications of unsupervised neural networks using Kohonen's self-organizing map approach. 316 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The idea for this book grew out of proposals at the APL86 con ference in Manchester which led to the initiation of the I-APL (International APL) project, and through it to the availability of an interpreter which would bring the advantages of APL within the means of vast numbers of school children and their teachers. The motivation is that once school teachers have glimpsed the possibilities, there will be a place for an 'ideas' book of short programs which will enable useful algorithms to be brought rapidly into classroom use, and perhaps even to be written and developed in front of the class. A scan of the contents will show how the conciseness of APL makes it possible to address a huge range of topics in a small number of pages. There is naturally a degree of idiosyncrasy in the choice of topics - the selection I have made reflects algo rithms which have either proved useful in real work, or which have caught my imagination as candidates for demonstrating the value of APL as a mathematical notation. Where appropriate, notes on the programs are intended to show the naturalness with which APL deals with the mathematics concerned, and to estab lish that APL is not, as is often supposed, an unreadable lan guage written in a bizarre character set.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 200 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The aim of this book is to provide a guide to a rich and fascinating subject: algebraic curves, and how they vary in families. The revolution that the field of algebraic geometry has undergone with the introduction of schemes, together with new ideas, techniques and viewpoints introduced by Mumford and others, have made it possible for us to understand the behavior of curves in ways that simply were not possible a half-century ago. This in turn has led, over the last few decades, to a burst of activity in the area, resolving longstanding problems and generating new and unforeseen results and questions. We hope to acquaint you both with these results and with the ideas that have made them possible. The book isn¿t intended to be a definitive reference: the subject is developing too rapidly for that to be a feasible goal, even if we had the expertise necessary for the task. Our preference has been to focus on examples and applications rather than on foundations. When discussing techniqueswe¿ve chosen to sacrifice proofs of some, even basic,results¿particularly where we can provide a good reference¿ in order to show how the methods are used to study moduli of curves. Likewise, we often prove results in special cases which we feel bring out the important ideas with a minimum of technical complication. 388 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Operator theory is a diverse area of mathematics which derives its impetus and motivation from several sources. It began with the study of integral equations and now includes the study of operators and collections of operators arising in various branches of physics and mechanics. The intention of this book is to discuss certain advanced topics in operator theory and to provide the necessary background for them assuming only the standard senior-first year graduate courses in general topology, measure theory, and algebra. At the end of each chapter there are source notes which suggest additional reading along with giving some comments on who proved what and when. In addition, following each chapter is a large number of problems of varying difficulty. This new edition will appeal to a new generation of students seeking an introduction to operator theory.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 216 pp. Englisch.

Buch. Condizione: Neu. Neuware -Mathematics is playing an ever more important role in the physical and biologi cal sciences, provoking a blurring of boundaries between scientific disciplines and a resurgence of interest in the modern as well as the classical techniques of applied mathematics. This renewal of interest, both in research and teaching, has led to the establishment of the series Texts in Applied Mathematics (TAM). The development of new courses is a natural consequence of a high level of excitement on the research frontier as newer techniques, such as numerical and symbolic computer systems, dynamical systems, and chaos, mix with and rein force the traditional methods of applied mathematics. Thus, the purpose of this textbook series is to meet the current and future needs of these advances and to encourage the teaching of new courses. TAM will publish textbooks suitable for use in advanced undergraduate and beginning graduate courses, and will complement the Applied Mathematics Sci ences (AMS) series, which will focus on advanced textbooks and research-level monographs. v Preface to the Second Edition The most significant differences between this edition and the first are as follows: ¿ Additional chapters and sections have been written, dealing with: nonlinear controllability via Lie-algebraic methods, variational and numerical approaches to nonlinear control, including a brief introduction to the Calculus of Variations and the Minimum Principle, - time-optimal control of linear systems, feedback linearization (single-input case), nonlinear optimal feedback, controllability of recurrent nets, and controllability of linear systems with bounded controls.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 552 pp. Englisch.

Buch. Condizione: Neu. Neuware -Develops the theory of initial-, boundary-, and eigenvalue problems, real and complex linear systems, asymptotic behavior and stability. Using novel approaches to many subjects, the book emphasizes differential inequalities and treats more advanced topics such as Caratheodory theory, nonlinear boundary value problems and radially symmetric elliptic problems. New proofs are given which use concepts and methods from functional analysis. Applications from mechanics, physics, and biology are included, and exercises, which range from routine to demanding, are dispersed throughout the text. Solutions for selected exercises are included at the end of the book. All required material from functional analysis is developed in the book and is accessible to students with a sound knowledge of calculus and familiarity with notions from linear algebra. This text would be an excellent choice for a course for beginning graduate or advanced undergraduate students.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 400 pp. Englisch.

Buch. Condizione: Neu. Neuware -This NATO Advanced Research Workshop was devoted to a specialized topic in molten salt chemistry and was held in an exotic location (as far as Westerners were concerned) well within the Arctic Circle. It nevertheless facilitated a fruitful week, both ofscience and ofhuman contacts. The 42 oral presentations and posters from nine countries enabled the 59 participants to learn a great deal about many areas of recent research in the molten salt chemistry of refractory metals, while making new contacts as well as renewing old friendships. The time ofinformal contact ledto the beginningofa numberofnew research cooperations with interchangeofpersonnel. Thus the twin aimsofadvancing science and improving East-West understanding were both amply fulfilled. Indeed a warm and happy family atmosphere was very tangible doth during the scientific sessions and the social events, which participants, accompanying persons and local staffall enjoyed. This opportunity of living for a short time within the Arctic Circle was a novelty for most Westerners, who generally appreciated the very warm weather (the hottest for 20 years according to some residents), as well as the beautiful surroundings ofvery green birch/pine forest, rushing rivers,vast lakes and rounded mountains,frequently illuminated by wonderful sunsets. The evening barbeque beside Lake Imandra (100 km long) and the coach tour beside the beautiful White Sea dotted with islands in the Kandalaksha Recreational Area (National Park), to sample Pomor culture, dancing and fresh salmon soup, were high spots ofthe social programme.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 292 pp. Englisch.

Buch. Condizione: Neu. Neuware -The motivation for this book comes from the apparent inability of existing orthodox location theory to throw light on a series of location-production problems which are typically faced by modem manufacturing and distribution ftrms. These problems are related to the treatment of time by ftrms, who normally view time costs in terms of inventory costs. From this perspective, traditional industrial location and linkage analysis can be re-cast in a form in which space time problems can be dealt with in a unifted manner. The role played by input factor prices and market prices in location behaviour becomes dependent on the relationship between the frequency of shipment and the distance of shipment. This approach provides new insights into the relationship between the optimal location of the ftrm and the value-added by the ftrm, under conditions of either ftxed or varying local factor prices. The approach can then also be extended to discuss the of the spatial changes involved in the new Just-In-Time (JIT) production question philosophy. I would like to acknowledge the many helpful discussions I have had with Bernard Fingleton, Masahisa Fujita, Geoff Hewings, John McCombie, Ron Miller, John Parr, Tony E. Smith, and my colleagues at the University of Reading.

Buch. Condizione: Neu. Neuware -When the socialist regime in Central and Eastern Europe (CEE) was overthrown around the end of the eighties, beginning of the nineties, an overall transforma tion of whole societies started. Not only the political and the economic systems of these countries, but all societal sectors underwent deep changes. These changes presented opportunities, but they also spelled trouble. On one hand, getting rid of stifling political control and excessive bureaucratic regulation was something which most members of these societies desired. On the other, it be came apparent very soon that the necessary and long hoped-for rebuilding of the economy, education, health care, the mass media, and science, too, was strongly restricted by the scarcity of financial resources. After a short period, during which opportunities were energetically taken up in a spirit of hope, came a long and still lasting time of growing troubles and despondency. Only in a few of the CEE countries have some glimpses of hope become visible recently; and it re mains to be seen whether these signals are reliable. Until now, therefore, the transformation dynamics of all societal sectors in all of the CEE countries have primarily been troublesome. This is surely true for the post-socialist research systems. I The demise of the communist party's abso lute rule over society has allowed researchers the public expression and the pur suit of goals whose common denominator has been a greater self-regulation of scientific research according to its own criteria and logic.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 188 pp. Englisch.

Buch. Condizione: Neu. Neuware -Food transportation represents a significant element of the food industry with major implications for food product costs, in terms of the direct costs associated with transportation, and those potentially larger ones associated with poor product and packaging quality which are consequences of inefficient and/or inappropriate operation. This handbook is for both the transporter and food producer, in that it bridges the interests and specializations of both. The book covers both the logistics and food science, and considers transport (i.e. land, sea, and air) as well as by its food sector.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 264 pp. Englisch.

Buch. Condizione: Neu. Neuware -Environmental Interactions of Clays is the companion volume of Bruce Velde's book on Origin and Mineralogy of Clays. In dealing with the role of clays in specific environmental issues, it is unique in its subject matter.Individual chapters are written by recognized international experts in their field. Subjects covered are radioactive waste disposal, trace metals, soil quality and productivity, pesticides, landfill, fibrous minerals and health.The approach is one of combining review with current research, thus it is an invaluable resource for students, researchers and practitioners alike.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 292 pp. Englisch.

Buch. Condizione: Neu. Neuware -This is the second volume in the series Nutrients in Ecosystems. Sulphur as an essential plant nutrient has received little attention. This is explained by the facts that sulphur was obviously in sufficient supply from the atmosphere, from soil and as a by-product in mineral fertilizers. Increases in the yield potential and thus in the nutrient requirement of modern crops, however, as well as remarkable changes in SO2 emissions by private households, power stations and industry, associated with legislative measures to reduce air and water pollution, have altered the situation to a large extent. In particular the public concerns about forest decline and pollution-induced climatic changes have initiated extensive research programs on the physiological functions of sulphur in plants, on the occurrence and plant availability of sulphur in agricultural and forest soils and on the chemistry of sulphur compounds in the tropo- and stratosphere.This book cannot be an encylcopedia of sulphur in all the media mentioned nor in all ecozones of the globe. However, it aims to give an overview of our present knowledge with a special focus on the sulphur situation in agrosystems of industrialised Western Europe. The ecological trends for sulphur observed in this region during recent decades are likely to be mirrored wherever industrialisation and urbanisation take place and where an increasing standard of living demands clean air, good drinking water and nutritious food. Agricultural production systems, therefore, require well-founded information on the actual sulphur nutrition and potential sulphur-fertilizer requirement of crops and soils respectively. It is hoped that this book will provide this information and will encourage further research where open questions still exist.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 236 pp. Englisch.

Buch. Condizione: Neu. Neuware -Heidegger holds that our age is dominated by the ambition of reason to possess the world. And he sees in Leibniz the man who formulated the theorem of our modern age: nothing happens without a reason. He calls this attitude `calculating thought' and opposes to it a kind of thought aimed at preserving the essence of things, which he calls `meditating thought'. Cristin's book ascribes great importance to this polarity of thinking for the future of contemporary philosophy, and thus compares the basic ideas of the two thinkers. Leibniz announces the conquest of reason; Heidegger denounces the dangers of reason. Their diversity becomes manifest in the difference between the idea of reason and the image of the path.But is Leibniz's thought really only `calculating' And do we not perhaps also encounter the traces of reason along Heidegger's path With these questions in mind we may begin to redefine the relation between the two thinkers and between two different conceptions of reason and philosophy. The hypothesis is advanced that Heidegger's harsh judgment of Leibniz may be mitigated, but it also becomes clear that Heidegger's rewriting of the code of reason is an integral part of our age, in which many signs point to new loci of rationality.With his original interpretation, aware of the risks he is taking, Renato Cristin offers a new guide to the understanding of reason: he shows forth Leibniz as one who defends the thought of being in the unity of monadology, and Heidegger as a thinker who preserves the sign of reason in his meditating thought.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 164 pp. Englisch.

Buch. Condizione: Neu. Neuware -This is the first book in healthcare ethics addressing the moral issues regarding ownership of the human body. Modern medicine increasingly transforms the body and makes use of body parts for diagnostic, therapeutic and preventive purposes. The book analyzes the concept of body ownership. It also reviews the ownership issues arising in clinical care (for example, donation policies, autopsy) and biomedical research. Societies and legal systems also have to deal with issues of body ownership. A comparison is made between specific legal arrangements in The Netherlands and France, as examples of legal approaches. In the final section of the book, different theoretical perspectives on the human body are analyzed: libertarian, personalist, deontological and utilitarian theories of body ownership.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 252 pp. Englisch.

Buch. Condizione: Neu. Neuware -More than ten million `poison gas' shells, mortar bombs, etc., lie hidden in Europe, many of them relics from World War I. Some were fired and failed to detonate, others were abandoned in old ammunition dumps. Most retain their load of chemical warfare (CW) agents. They are turned up daily in the course of farming and construction. Many European nations have permanent departments concerned with their collection and destruction. Old munitions, when discovered, are usually heavily corroded and difficult to identify. Is it a CW munition Or an explosive If CW, what agent does it contain Once identified, one has to select a destruction method. Some of the methods that have been proposed are less than perfect, and are often complicated by the presence of extraneous chemicals, either mixed with the CW agents during manufacture or formed over decades in the ground. Of particular interest are the insiders' reports on the German CW programmes of both World Wars, and the current status of Russian chemical armaments.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 224 pp. Englisch.

Buch. Condizione: Neu. Neuware -The book is essential for food manufacturers using HACCP procedures to ensure quality control. In particular, it offers practical information for production engineers and quality assurance personnel involved in minimizing the risk of foreign body contamination reaching the consumer. Recent developments in both technology and techniques are assessed and compared to more established methods in order to provide the most up-to-date and pragmatic advice for food manufacturers.The major sources of foreign body contamination are shown and the methods and machinery available to prevent food adulteration are analyzed. The capabilities and limitations of the machines used to remove foreign matter from food are considered in detail. It describes the detection methods available and how they are used in the food industry. In particular the capabilities and limitations of the machines used is dealt with in sufficient detail for them to be understood by technologists and scientists from disciplines other than engineering.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 380 pp. Englisch.

Buch. Condizione: Neu. Neuware -Covering a wide range of disciplines, this book explains the formulae, techniques, and methods used in field ecology. By providing an awareness of the statistical foundation for existing methods, the book will make biologists more aware of the strengths and possible weaknesses of procedures employed, and statisticians more appreciative of the needs of the field ecologist.Unique to this book is a focus on ecological data for single-species populations, from sampling through modeling. Examples come from real situations in pest management, forestry, wildlife biology, plant protection, and environmental studies, as well as from classical ecology. All those using this book will acquire a strong foundation in the statistical methods of modern ecological research.This textbook is for late undergraduate and graduate students, and for professionals.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 584 pp. Englisch.

Buch. Condizione: Neu. Neuware -In recent years, the study of events and their role as implicit arguments of predicates has been at the center of much important work in semantics and the syntax/semantics interface. This volume brings together fourteen original studies by leading scholars in semantics and the syntax/semantics interface, covering a broad spectrum of research into the role of events in grammar. The papers extensively address the following topics, among others: event arguments and thematic argument structure; the role of events in verbal aspectual distinctions; events and the distinction between stage and individual level predicates; the role of events in the analysis of plurality and scope relations, the mass/count distinction, and propositional attitudes.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 396 pp. Englisch.

Buch. Condizione: Neu. Neuware -The idea for this book was born at the June 1996 meeting of the IDEAL Steering Committee in Milwaukee, Wisconsin. We had just completed a successful and stimulating special symposium during the annual meeting of the American Society for Limnology and Oceanography, and enthusiasm was running high for the production of a volume that could assemble in one place the scientific findings that were starting to emerge from East Africa. IDEAL, an International Decade for the East African Lakes, had ended one round of field investigations, many of which had been centered on Lake Victoria. As the climatologists, geologists, paleolimnologists, and biologists displayed their results and debated interpretations, it appeared that some paradigms were shifting, and that new explanations of climate history and modem processes were taking shape. The Steering Committee endorsed the production of a volume that would draw together the different research results that were emerging and which would be representative of the scope of science issues that exist within IDEAL. This book follows in the spirit of The Limnology, Climatology, and Paleoclimatology of the East African Lakes, published in 1996, but has a somewhat different purpose. The previous publication also included original science results, but it was conceived to review the state of knowledge, identify critical problems, and point to new paths of inquiry. It accompanied the development of our first Science and Implementation Plan for the East African Lakes.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 260 pp. Englisch.

Buch. Condizione: Neu. Neuware -The nitrogen-containing ring structures are at the hub of metabolism and include ATP, nucleic acids, many coenzymes, metabolic regulators and integrators such as adenosine and GTP, signalling compounds such as cyclic nucleotides and plant cytokinins and biochemically functional pigmets of which haemoglobin, the cytochromes and chlorophyll are examples.This important book collates and integrates current knowledge of all the biologically important N-heterocyclic compounds, covering the relationship between their chemical structures and physiological functions within this key group of compounds. Few biochemical reaction sequences do not involve one of these compounds as a substrate, product or coenzyme and a full understanding of the interrelationship between their structure and function is vital for all those woorking in the field of biochemistry.Professor Eric Brown who has a huge wealth of experience in teaching and research on these compounds has written a very comprehensible and thorough book which will be of great value for advanced students and researchers in biochemistry and those at the interfacing subject areas of chemistry, biology and pharmacology including all those employed in researching biological function within pharmaceutical companies.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 260 pp. Englisch.
