Buch. Condizione: Neu. Neuware -The book Partial Differential Equations through Examples and Exercises has evolved from the lectures and exercises that the authors have given for more than fifteen years, mostly for mathematics, computer science, physics and chemistry students. By our best knowledge, the book is a first attempt to present the rather complex subject of partial differential equations (PDEs for short) through active reader-participation. Thus this book is a combination of theory and examples. In the theory of PDEs, on one hand, one has an interplay of several mathematical disciplines, including the theories of analytical functions, harmonic analysis, ODEs, topology and last, but not least, functional analysis, while on the other hand there are various methods, tools and approaches. In view of that, the exposition of new notions and methods in our book is 'step by step'. A minimal amount of expository theory is included at the beginning of each section Preliminaries with maximum emphasis placed on well selected examples and exercises capturing the essence of the material. Actually, we have divided the problems into two classes termed Examples and Exercises (often containing proofs of the statements from Preliminaries). The examples contain complete solutions, and also serve as a model for solving similar problems, given in the exercises. The readers are left to find the solution in the exercises; the answers, and occasionally, some hints, are still given. The book is implicitly divided in two parts, classical and abstract.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 420 pp. Englisch.

Buch. Condizione: Neu. Neuware -This is a translation of Edmund HusserI's lecture course from the Summer semester 1907 at the University of Gottingen. The German original was pub lished posthumously in 1973 as Volume XVI of Husserliana, Husserl's opera omnia. The translation is complete, including both the main text and the supplementary texts (as Husserliana volumes are usually organized), except for the critical apparatus which provides variant readings. The announced title of the lecture course was 'Main parts of the phenome nology and critique of reason.' The course began with five, relatively inde pendent, introductory lectures. These were published on their own in 1947, bearing the title The idea ojphenomenology.l The 'Five Lectures' comprise a general orientation by proposing the method to be employed in the subsequent working out of the actual problems (viz., the method of 'phenomenological reduction') and by clarifying, at least provisionally, some technical terms that will be used in the labor the subsequent lectures will carry out. The present volume, then, presents that labor, i.e., the method in action and the results attained. As such, this text dispels the abstract impression which could not help but cling to the first five lectures taken in isolation. Accord ingly, we are here given genuine 'introductory lectures,' i.e., an introduction to phenomenology in the genuine phenomenological sense of engaging in the work of phenomenology, going to the 'matters at issue themselves,' rather than remaining aloof from them in abstract considerations of standpoint and approach.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 386 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The tension between art and science may be traced back to the Greeks. What became 'natural philosophy' and later 'science' has traditionally been posed as a fundamental alternative to poetry and art. It is a theme that has commanded central attention in Western thought, as it captures the ancient conflict of Apollo and Dionysus over what deserves to order our thought and serve as the aspiration of our cultural efforts. The modern schi sm between art and science was again clearly articulated in the Romantic period and seemingly grew to a crescendo fifty years aga as a result of the debate concerning atomic power. The discussion has not abated in the physical sciences, and in fact has dramatically expanded most prominently into the domains of ecology and medicine. Issues concerning the role of science in modern society, although heavily political, must be regarded at heart as deeply embedded in our cultural values. Although each generation addresses them anew, the philosophical problems which lay at the foundation of these fundamental concerns always appear fresh and difficult. This anthology of original essays considers how science might have a greater commonality with art than was perhaps realized in a more positivist era. The contributors are concerned with how the aesthetic participates in science, both as a factor in constructing theory and influencing practice. The collec tion is thus no less than a spectrum of how Beauty and Science might be regarded through the same prism.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 356 pp. Englisch.

Buch. Condizione: Neu. Neuware -Descartes' philosophy represented one of the most explicit statements of mind-body dualism in the history of philosophy. Its most familiar expression is found in the Meditations (1641) and in Part I of The Principles 0/ Philosophy (1644). However neither of these books provided a detailed discussion of dualism. The Meditations was primarily concerned with finding a foundation for reliable human knowledge, while the Principles attempted to provide an alternative metaphysical framework, in contrast with scholastic philosophy, within which natural philosophy or a scien tific explanation of natural phenomena could be developed. Thus neither book ex plicitly presents a Cartesian theory of the mind nor does either give a detailed account of how, if dualism were accepted, mind and body would interact. The task of articulating such a theory was left to two further works, only one of which was completed by Descartes, viz. the Treatise on Man (published posthumously in 1664). The Treatise began with the following sentence, describing the hypothetical human beings who were to be explained in that work: 'These human beings will be com posed, as we are, of a soul and a body; and, first of all, I must describe the body for you separately; then, also separately, the soul; and fmally I must show you how these two natures would have to be joined and united to constitute human beings resembling us. 276 pp. Englisch.

Buch. Condizione: Neu. Neuware -The book integrates for the first time existing ecosystem theories and is therefore able to present a full ecological and theoretical pattern. It shows that we are able to understand ecosystems and their reactions, provided that we use all basic systems ecology for different aspects of ecosystem properties. The first edition of this book was published in 1992. This second edition contains the many recently published and presented contributions on ecosystem theories, which show even more strongly that an integration of the existing ecosystem theories is needed and also possible. 404 pp. Englisch.

Buch. Condizione: Neu. Neuware -One service mathematics has rendered the human race. It has put common sense back where it belongs. It has put common sense back where it belongs, on the topmost shelf next to the dusty canister labelled discarded nonsense. Eric TBell Every picture tells a story. Advenisement for for Sloan's backache and kidney oils, 1907 The book you have in your hands as you are reading this, is a text on3-dimensional topology. It can serve as a pretty comprehensive text book on the subject. On the other hand, it frequently gets to the frontiers of current research in the topic. If pressed, I would initially classify it as a monograph, but, thanks to the over three hundred illustrations of the geometrical ideas involved, as a rather accessible one, and hence suitable for advanced classes. The style is somewhat informal; more or less like orally presented lectures, and the illustrations more than make up for all the visual aids and handwaving one has at one's command during an actual presentation.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 356 pp. Englisch.

Buch. Condizione: Neu. Neuware -Thomas Sheehan and Richard E. Palmer The materials translated in the body of this volume date from 1927 through 1931. The Encyclopaedia Britannica Article and the Amsterdam Lectures were written by Edmund Hussed (with a short contribution by Martin Heideg ger) between September 1927 and April 1928, and Hussed's marginal notes to Sein und Zeit and Kant und das Problem der Metaphysik were made between 1927 and 1929. The appendices to this volume contain texts from both Hussed and Heidegger, and date from 1929 through 1931. As a whole these materials not only document Hussed's thinking as he approached retirement and emeri tus status (March 31, 1928) but also shed light on the philosophical chasm that was widening at that time between Hussed and his then colleague and protege, Martin Heidegger. 1. The Encyclopaedia Britannica Article Between September and early December 1927, Hussed, under contract, composed an introduction to phenomenology that was to be published in the fourteenth edition ofthe Encyclopaedia Britannica (1929). Hussed's text went through four versions (which we call Drafts A, B, C, and D) and two editorial condensations by other hands (which we call Drafts E and F). Throughout this volume those five texts as a whole are referred to as 'the EB Article' or simply 'the Article. ' Hussed's own final version of the Article, Draft D, was never published of it appeared only in 1962.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 536 pp. Englisch.

Buch. Condizione: Neu. Neuware -Spatial and temporal averaging of observational data is widely used in many problems of meteorology, hydrology and related sciences. Several averaging methods have been proposed by various scientists and are used on a regular basis to obtain data averaged in space orfand in time, to yield data which are less influenced by random factors than initial point data are. The significance of averaging meteorological fields has substantially increased nowadays in connection with the problem of global climate change. However important as such change may be, it is very small as compared with the natural variability of atmospheric fields. An accurate averaging is absolutely necessary in order to discover a small climate change signal on the background of strong natural variability that acts as a random noise in this context. It is highly desirable not only to determine the averaged values themselves, but also to estimate the accuracy with which these values are known. To evaluate the accuracy of averaging is not a simple task mainly because the initial point values are not independent from each other, and interconnections between them substantially influence the averaging accuracy.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 296 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -There is now a considerable literature on chemical ecology, which had its beginnings in the study of insect pheromones. This beginning was possible only by combining the disciplines and techniques of biology and chemistry. For a biologist, it is difficult to understand the time frames of analytical and synthetic chemistry. A compound may take days to characterize and be available in minutes from a bottle on the shelf, or it may take years to characterize and synthesize. Chemists have a similar frustration: after an intense programme of work, the insect in question may not emerge for many months. study are, however, The rewards of integrated interdisciplinary considerable, because they allow us to understand many facets of insect behaviour and consequently to control that behaviour for our own ends. In this book, we have set out to explain the results of research from chemical and biological perspectives, and see how the knowledge gained has led to novel techniques that can be used ininsect pest management and insect control. An important part of understanding insect chemical ecology involves the understanding not only of new concepts but of the vocabularies used by scientists specializing in different fields. It will be clear that the three sections of this book have been written by three different people: an insect behaviourist, an organic chemist and a biologist in industry.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 384 pp. Englisch.

Buch. Condizione: Neu. Neuware -Upon hearing that Ronald Coase had been awarded the Nobel Prize, a fellow economist's first response was to ask with whom Coase had shared the Prize. Whether this response was idiosyncratic or not, I do not know; I expect not. Part of this type of reaction can no doubt be explained by the fact that Coase has often been characterized as an economist who wrote only two significant or influential papers: 'The Nature of the Firm' (1937) and 'The Problem of Social Cost' (1960). And by typical professional standards of 'significant' and 'influential' (i. e. , widely read and cited), this perception embodies a great deal of truth, even subsequent to Coase's receipt of the Prize. This is not to say that there have not been other important works - 'The Marginal Cost Controversy' (1946) and 'The Lighthouse in Economics' (1974) come immediately to mind here - only that in a random sample of, say, one hundred economists, one would likely find few who could list a Coase bibliography beyond the two classic pieces noted above, in spite of Coase's significant publication record. ' The purpose of this collection is to assess the development of, tensions within, and prospects for Coasean Economics - those aspects of economic analysis that have evolved out of Coase's path-breaking work. Two major strands of research can be identified here: law and economics and the New Institutional Economics.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 292 pp. Englisch.

Buch. Condizione: Neu. Neuware -It has been more than five decades ago that Henk van de Hulst predicted the observability of the 21-cm line of neutral hydrogen (HI ). Since then use of the 21-cm line has greatly improved our knowledge in many fields and has been used for galactic structure studies, studies of the interstellar medium (ISM) in the Milky Way and other galaxies, studies of the mass distribution of the Milky Way and other galaxies, studies of spiral struc ture, studies of high velocity gas in the Milky Way and other galaxies, for measuring distances using the Tully-Fisher relation etc. Regarding studies of the ISM, there have been a number of instrumen tal developments over the past decade: large CCD's became available on optical telescopes, radio synthesis offered sensitive imaging capabilities, not only in the classical 21-cm HI line but also in the mm-transitions of CO and other molecules, and X-ray imaging capabilities became available to measure the hot component of the ISM. These developments meant that Milky Way was no longer the exclusive playground for ISM studies and that by reaching out to other galaxies astronomy had gained the advantage of having an 'outside' view, though at the expense of giving up some linear resolution. Studies of the ISM in other galaxies are intimately connected to studies of the ISM in the Milky Way.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 226 pp. Englisch.

The Volume consists of contributions by leading experts in the field written specifically for this volume. No comparable volume currently exists.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 340 pp. Englisch.

Buch. Condizione: Neu. Neuware -This text brings together disparate bodies of ecological knowledge pertinent to countryside areas used for recreation. It summarizes our understanding of recreation as an ecological factor and outlines the problems needing further research, for the benefit of students and others concerned with countryside conservation. Information is drawn from several countries and the text highlights common features as a means for providing a theoretical base for practical advice which the planner or manager can use as a guide when faced with problems for which there is no direct information.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 672 pp. Englisch.

Buch. Condizione: Neu. Neuware -Since the publication of the first edition of The Physics of Glassy Polymers there have been substantial developments in both the theory and application of polymer physics, and many new materials have been introduced. Furthermore, in this large and growing field of knowledge, glassy polymers are of particular interest because of their homogeneous structure, which is fundamentally simpler than that of crystalline or reinforced materials. This new edition covers all these developments, including the emergence of the polymer molecule with its multiplicity of structure and conformations as the major factor controlling the properties of glassy polymers, using the combined knowledge of a distinguished team of contributors. With an introductory chapter covering the established science in the subject are and summarising concepts assumed in the later chapters, this fully revised and updated second edition is an essential work of reference for those involved in the field. 524 pp. Englisch.

Buch. Condizione: Neu. Neuware -Honeycomb Technology is a guide to honeycomb cores and honeycomb sandwich panels, from the manufacturing methods by which they are produced, to the different types of design, applications for usage and methods of testing the materials. It explains the different types of honeycomb cores available and provides tabulated data of their properties. The author has been involved in the testing and design of honeycomb cores and sandwich panels for nearly 30 years. Honeycomb Technology reflects this by emphasizing a `hands-on' approach and discusses procedures for designing sandwich panels, explaining the necessary equations. Also included is a section on how to design honeycomb energy absorbers and one full chapter discussing honeycomb core and sandwich panel testing. Honeycomb Technology will be of interest to engineers in the aircraft, aerospace and building industries. It will also be of great use to engineering students interested in basicsandwich panel design.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 252 pp. Englisch.

Buch. Condizione: Neu. Neuware -This book is a revised and extended version of my PhD Thesis 'Logical Tools for Modelling Legal Argument', which I defended on 14 January 1993 at the Free University Amsterdam. The first five chapters of the thesis have remained almost completely unchanged but the other chapters have undergone considerable revision and expansion. Most importantly, I have replaced the formal argument-based system of the old Chapters 6, 7 and 8 with a revised and extended system, whieh I have developed during the last three years in collaboration with Giovanni Sartor. Apart from some technical improvements, the main additions to the old system are the enriehment of its language with a nonprovability operator, and the ability to formalise reasoning about preference criteria. Moreover, the new system has a very intuitive dialectieal form, as opposed to the rather unintuitive fixed-point appearance of the old system. Another important revision is the split of the old Chapter 9 into two new chapters. The oldSection 9. 1 on related research has been updated and expanded into a whole chapter, while the rest of the old chapter is now in revised form in Chapter 10. This chapter also contains two new contributions, a detailed discussion of Gordon's Pleadings Game, and a general description of a multi-Iayered overall view on the structure of argu mentation, comprising a logieal, dialectical, procedural and strategie layer. Finally, in the revised conclusion I have paid more attention to the relevance of my investigations for legal philosophy and argumentation theory.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 332 pp. Englisch.

Buch. Condizione: Neu. Neuware -The use of adhesives has many advantages over other methods of fastening. Presenting a smooth exterior, spreading of the load and ease of joining thin or dissimilar materials are all reasons why the use of adhesives for bonding structures is steadily growing and finding new applications.Structural Adhesive Joints in Engineering is a concise guide to adhesive joints within structures, especially those capable of bearing high loads. The book covers all aspects of design, materials selection and testing, including the physical properties and cure-chemistry of structural adhesives and how to select adhesives for particular applications; surface preparation by physical or chemical methods (with or without the use of primers and coupling agents); and new sections on surface analysis and water durability. There is also a detailed guide to stresses in adhesive joints and joint design. Thoroughly revised and updated since the first edition, the Second Edition contains new sections on recent topics of importance, such as water durability.This book contains everyhting an engineer needs to know to be able to design and produce adhesively bonded joints that are required to carry significant loads. Advantages and disadvantages are given, together with a sufficient description of the necessary mechanics and chemistry involved to enable the designer to make a sound engineering judgement in each particular case.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 380 pp. Englisch.

Buch. Condizione: Neu. Neuware -The first edition was produced at a time when the advantages of studying oriented polymers were just becoming apparent. From a sci entific stand point it had been demonstrated that greater insight into both structure and properties could be obtained if an oriented polymer was prepared. From a technological viewpoint, major advances were under way, especially in high modulus and high strength fibres. Twenty years later, it is possible to review the scientific advances which have been made in this area and to provide much wider perspectives for the technology. As in the case of the first edition, the emphasis is on the methodologies available for characterizing oriented polymers and their mechanical behaviour. It is a particular pleasure to thank the contributing authors for their cooperation and Dr Philip Hastings of Chapman & Hall for his support and encouragement. I am also indebted to Professors A. H. Windle and D. C. Bassett for their respective contributions to sections 1. 3. 1 and 1. 3. 4. Although this chapter has been extensively revised, the contribution of the late Leslie Holliday to the first edition of this book is also acknowledged. Introduction 1 I. M. Ward 1. 1 THE PHENOMENON OF ORIENTATION Orientation in polymers is a phenomenon of great technical and theo retical importance. The word orientation itself conveys a number of ideas.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 552 pp. Englisch.

Buch. Condizione: Neu. Neuware -Manufactured Fibre Technology provides an accessible and comprehensive treatment of the chemical, physical and mechanical processes involved in the production of all important commodity manufactured fibres and most of the industrial fibres. The emphasis is on the fundamental principles and industrial aspects of production. Latest developments in manufactured fibres in terms of manufacturing processes, characteristics and their applications are also covered. Manufactured Fibre Technology is designed around twenty chapters with a balance of basic principles and production of specific fibre types. Newer and industrially relevant areas such as high speed spinning, production of speciality fibres (including microfibres), computer simulation of spinning, high performance fibres, spun-bonding and melt-blowing, and re-use of fibre waste are included. The structure, property and application areas of each fibre type are also discussed, thus providing a broad understanding of the subject. In addition, various aspects related to the testing and characterisation of fibres and polymers are reviewed. This book is an invaluable resource to students, lecturers, industrial technologists and researchers in this subject area.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 692 pp. Englisch.

Buch. Condizione: Neu. Neuware -This book is based mainly on invited and offered papers presented at the Second International Symposium on Bacterial and Bacteria-like Contaminants of Plant Tissue Cultures held at University College, Cork, Ireland in September 1996, with additional invited papers. The First International Symposium on Bacterial and Bacteria-like Contaminants of Plant Tissue Cultures was held at the same venue in 1987 and was published as Acta Horticulturae volume 225, 1988. In the intervening years there have been considerable advances in both plant disease diagnostics and in the development of structured approaches to the management of disease and microbial contamination in micropropagation. These approaches have centred on attempts to separate, spatially, the problems of disease transmission and laboratory contamination. Disease-control is best achieved by establishing pathogen-free cultures while laboratory contamination is based on subsequent good working practice. Control of losses due to pathogens and microbial contamination in vitro addresses, arguably, the most importance causes of losses in the industry; nevertheless, losses at and post establishment can also be considerable due to poor quality microplants or micro-shoots. In this symposium, a holistic approach to pathogen and microbial contamination control is evident with the recognition that micropropagators must address pathogen and microbial contamination in vitro, and diseases and microplant failure at establishment. There is increasing interest in establishing beneficial bacterial and mycorrhizal association with microplants in vitro and in vivo.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 388 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -During the next 30 years, farmers must produce 70% more rice than the 550 millions tons produced today to feed the increasing population. Nitrogen (N) is the nutrient that most frequently limits rice production. At current levels ofN use efficiency, we will require at least double the 10 million tons of N fertilizer that are currently used each year for rice production. Global agriculture now relies heavily on N fertilizers derived from petroleUIll, which, in turn, is vulnerable to political and economic fluctuations in the oil markets. N fertilizers, therefore, are expensive inputs, costing agriculture more than US$45 billion annually. Rice suffers from a mismatch of its N demand and N supplied as fertilizer, resulting in a 50-70% loss of applied N fertilizer. Two basic approaches may be used to solve this problem One is to regulate the timing ofN application based on needs of the plants, thus partly increasing the efficiency of the plants' use of applied N. The other is to increase the ability of the rice system to fix its own N. The latter approach is a long-term strategy, but it would have enormous environmental benefits while helping resource-poor farmers. Furthermore, farmers more easily adopt a genotype or variety with useful traits than they do crop and soil management practices that may be associated with additional costs. 228 pp. Englisch.
