Taschenbuch. Condizione: Neu. Neuware -The suggestion that quantum-mechanical tunnelling might be a significant factor in some chemical reactions was first made fifty years ago by Hund, very soon after the principles of wave mechanics had been established by de Broglie, Schrodinger and Heisenberg, and similar ideas were put forward during the following thirty years by a number of authors. It was realised from the beginning that such effects would be particularly prominent in reactions involving the movement of protons or hydrogen atoms, and both theoretical and experimental work received a powerful stimulus in the discovery of deuterium in 1932. During the last twenty years theoretical predictions about the tunnel effect have been supported by an increasing body of experimental evidence, derived especially from studies of hydrogen isotope effects. The present book presents an attempt to summarize this evidence and to indicate the main lines of the basic theory. Details of mathematical manipu lation are restricted mainly to Chapter 2 and the Appendices, and many readers may prefer to confine themselves to the results obtained. The main emphasis has been on the kinetics of chemical reactions involving the transfer of protons, hydrogen atoms or hydride ions, although Chapter 6 gives an account of the role of the tunnel effect in molecular spectra, and Chapter 7 makes some mention of tunnelling in solid state phenomena, biological processes and the electrolytic discharge of hydrogen. Only passing references have been made to tunnelling by electrons.

Neuware - The objective of this text is to develop and implement a model for allocating the industries of the Sectorial Programs of Industrial Development of the Andean Common Market. In the Andean Common Market, as in most other integration schemes among less developed countries, the main expectations regarding the promotion of economic growth are based on the expectation of increased opportunities for import substituting industrialization. The concern here is with the Andean Common Market in particular because it has been the economic integration scheme that has most explicitly recognized the objective of the less developed countries of taking advantage of the new opportunities for industrial ization created by the combination of the individual markets. In the Andean Common Market the importance attached to the expectation of the gains from industrialization was expressed in the formulation of Sectorial Programs of Industrial Development. Other integration schemes among less developed coun tries have not addressed the issue of import substituting industrialization in such detailed manner. In the first section of this chapter the importance of the topic of allocating industries in integration schemes among less developed countries is discussed. It is argued that the benefits to be derived from increased trade in the traditional products of the member countries are minimal. Instead, the member countries 1 2 ALLOCATION OF INDUSTRY IN THE ANDEAN COMMON MARKET expect the benefits from economic integration schemes to be derived from the utilization of the opportunities for industrialization created by such schemes.

This item is printed on demand - it takes 3-4 days longer - Neuware -SINCE THE EARLY DAYS OF MICROBIOLOGY IT HAS BEEN KNOWN THAT, during their life cycles, microorganisms exhibit developmental changes in common with other organisms. In the last decade interest in this aspect of microbiology has developed greatly, and research findings have provided an understanding of the genetic, molecular and biochemical bases of development. An important stimulus in this research has been the realis ation that microbial development, in its various forms, provides interest ing model systems that have relevance to a much wider understanding of the developmental processes in higher eukaryotes. Many undergraduate and other courses in microbiology reflect these developments. Up to now, the only source material for these courses has been symposia publications, or books of a more specialised nature and at an advanced level. The aim in writing this book, which is based on a series of undergraduate lectures given at the University of Nottingham, was to bring together the relevant aspects of the biology of microorganisms, in particular the bacteria and fungi. The algae and protozoa have been excluded, partly because of the limits of space and partly because they are very different from the bacteria and fungi in most aspects of their biology. 244 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This book is first of all designed as a text for the course usually called 'theory of functions of a real variable'. This course is at present cus tomarily offered as a first or second year graduate course in United States universities, although there are signs that this sort of analysis will soon penetrate upper division undergraduate curricula. We have included every topic that we think essential for the training of analysts, and we have also gone down a number of interesting bypaths. We hope too that the book will be useful as a reference for mature mathematicians and other scientific workers. Hence we have presented very general and complete versions of a number of important theorems and constructions. Since these sophisticated versions may be difficult for the beginner, we have given elementary avatars of all important theorems, with appro priate suggestions for skipping. We have given complete definitions, ex planations, and proofs throughout, so that the book should be usablefor individual study as well as for a course text. Prerequisites for reading the book are the following. The reader is assumed to know elementary analysis as the subject is set forth, for example, in TOM M. ApOSTOL'S Mathematical Analysis [Addison-Wesley Publ. Co., Reading, Mass., 1957], or WALTER RUDIN'S Principles of Mathe nd matical Analysis [2 Ed., McGraw-Hill Book Co., New York, 1964]. 488 pp. Englisch.

This is our underlying faith, that details of seismic waveshapes can tell us the details of the nature of the earth. But their voices are obscured by many irrelevancies. They speak in a high-noise environment, and we have been able to decipher only a small portion. However, things are looking up: better tech niques are lessening the irrelevancies, and we are learning to read. In exploration of unknown areas, determining the nature of the rocks present is often the difficult aspect. Most of the properties of rocks that can be measured at a distance are not distinctive enough to identify the rock unambiguously. Con ventionally, seismic data are used to determine aspects of the structure. Stratigraphic pictures are inferred from the struc ture, the nature of rocks exposed for examination in the sur rounding area, and regional concepts. Three points make seismic stratigraphy feasible now: (1) we have better data quality, (2) we have begun to sys tematize analysis procedures, and (3) we believe in the geologic significance of waveshape details. 252 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This book is intended primarily for the doctor who is confronted with an electro cardiogram and who wishes to make his own interpretation rather than to rely entirely upon the report of a specialist. The clinical use of the electrocardiogram is the sole concern here and no attempt is made to describe electrophysiology. It is hoped that by beginning with a description of the P wave and its abnormalities the reader will gain confidence and the desire to continue to subsequent sections as he realizes the simplicity of the approach. In a further attempt towards clarity and ease of reading, the text is liberally interspersed with line drawings, all originated by the author, and at the end of each section electro cardiograms are provided, illustrating the abnormalities which have been described. Interest in the electrocardiogram has now spread from the cardiologist to a wide variety of hospital staff, including medical students, house officers, intensive care and coronary care nurses, and anaesthetists. Many general practitioners now record their own electro cardiograms and most have outpatient access to the electrocardiography department of their local hospitals. This book will provide a useful basis for their reading of the electrocardiogram and I hope convince them that its interpretation is well within their capabilities. 148 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The development of immunisation has been one of the most striking features in the control of infectious disease in the twentieth century. This book takes into account the need for a simple, concise account of immunisation procedures not only in the UK and USA but also in other countries, and to this end a special chapter on immunisation in developing countries has been included. Following two introductory chapters, there are nine chapters on various diseases and the vaccines that have been developed to combat them. In each of these chapters, a short discussion of the epidemiology of the disease and the history of immun isation against it is followed by a description of the vaccine, its efficacy, contraindications to its use and future developments. The book concludes with four general chapters on vaccines for travel, vaccines for selective use, passive immunisation and immunisation in tropical environments. The demand for this book follows the popularity of a series of articles on immunisation which appeared in Update. These have been expanded and largely rewritten. I have drawn on many expert sources and have made an effort to provide a balanced and non-controversial opinion with a discussion of alternative procedures where indicated. Immunisation is intended not only for the family practitioner but also for many specialists, particularly paediatricians, community physicians, Armed Forces medical officers, and all those concerned with immigration procedures and with the spread of infectious diseases. Medical students, nurses and para medical staff will also find much of value. 164 pp. Englisch.

The ISEB were established to provide 'a forum for uninhibited exchange of information and ideas among the biological, chemical, atmospheric and geolorical scientists working in the common area of biogeochemistry, encompassing soil and other earth sciences as well as the hydrosphere and atmosphere', By linking the fourth ISEB with the Leachin~ Conference the scope of discussions was extended to encompass the application of biogeochemical processes to the mining industry. This wide-ranging philosophy is reflected in the breadth and diversity of the subjects covered in this book. The published papers are expanded versions of those presented at the meetings. They have all been scrutinized by at least one referee in addition to the editors. About 20% of the contributions to the meetings are not included, either because authors did not wish to publish or because the papers were not accepted by the editors. 740 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This volume consists of a selection of papers presented at a 'Symposium on Mathematical Modelling in Biology and Ecology', held at the Conference Centre of the Council for Scientific and Industrial Research (CSIR), Pretoria, South Africa on July 5 and 6, 1979. The Symposium was organized by the National Research Institute for Mathematical Sciences of the CSIR, the National Institute of Virology, the University of the Witwaters= rand and the South African Journal of Science. The primary reason for the symposium was to provide a forum for South African researchers in the fields of Mathematical Biology and Ecology, at which to present or review their most recent work. It was also hoped that such a symposium would stimulate further research in this field in South Africa and elsewhere. Accordingly a number of South African Scien= tists working on a wide range of problems in Mathematical Biology and Ecology and three Scientists from North America, were invited to present papers. Although a somewhat wide spectrum of problems was covered by the Symposium, a balance was maintained by ensuring that the papers were evenly distributed in the three categories: Models of Physiological Pro= cesses; Morphological Models; and Ecological and Population Models. 372 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -A vascular system consists of a supplying arterial and a draining venous part which are connected by a terminal vascular network. The arterial segment can be characterized according to the structural features of the vessel wall. However, it is sometimes diffi cult to distinguish the capillary from the postcapillary vessels on the basis of structural features alone. On the other hand, physiologic qualities such as permeability can hard ly be associated with an equivalent histologic pattern of the vessel wall (lllig 1961; Rhodin 1967, 1968; Hauck 1971; Westergaard 1974). A defmition of a vascular seg ment based on biologic significance should combine morphological and functional qualities of the vessel walls. During the ontogeny of the mammalian organism a variety of vascular patterns (e. g. , distribution of arteries and veins, arrangement of the capillaries) has been formed typical of each organ (Wolff et al. 1975; Baez 1977). The capillaries connect the feed ing arterioles and the collecting venules in two different ways according to the branch ing pattern of the terminal vessels (Hauck 1975, Wolff et al. , 1975). The arterioles and venules are directly connected by capillary segments. Consequently a terminal vessel called arteriovenous (a-v) capillary results, or a closely meshed capillary network is de veloped which connects arterioles and venules by a variable number of small capillary branches arranged parallel to the preexisting a-v capillary. 76 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The goal of this book is to present local class field theory from the cohomo logical point of view, following the method inaugurated by Hochschild and developed by Artin-Tate. This theory is about extensions-primarily abelian-of 'local' (i.e., complete for a discrete valuation) fields with finite residue field. For example, such fields are obtained by completing an algebraic number field; that is one of the aspects of 'localisation'. The chapters are grouped in 'parts'. There are three preliminary parts: the first two on the general theory of local fields, the third on group coho mology. Local class field theory, strictly speaking, does not appear until the fourth part. Here is a more precise outline of the contents of these four parts: The first contains basic definitions and results on discrete valuation rings, Dedekind domains (which are their 'globalisation') and the completion process. The prerequisite for this part is a knowledge of elementary notions of algebra and topology, which may be found for instance in Bourbaki. The second part is concerned with ramification phenomena (different, discriminant, ramification groups, Artin representation). Just as in the first part, no assumptions are made here about the residue fields. It is in this setting that the 'norm' map is studied; I have expressed the results in terms of 'additive polynomials' and of 'multiplicative polynomials', since using the language of algebraic geometry would have led me too far astray. 256 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book provides an introduction to the analysis of multivariate data. It should be suitable for statisticians and other research workers who are familiar with basic probability theory and elementary inference, and also have a basic grounding in matrix algebra. The book should also be suitable as a text for undergraduate and postgraduate statistics courses on multivariate analysis. The book covers a wider range oftopics than some other books in this area. It deals with preliminary data analysis, principal component and factor analysis and traditional normal-theory material. It also covers cluster analysis and scaling techniques. In writing the book, we have tried to provide a reasonable blend of theory and practice, in contrast to much of the existing literature which concentrates on one or other aspect. Enough theory is given to introduce the concepts and to make the topics mathematically interesting. But we also discuss the use (and misuse) of the techniques in practice and present appropriate real-life examples. Although the book is primarily an introductory text, we have nevertheless added appropriate references for further reading, so that the reader may extend his studies if he wishes. 260 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -In 1924 the firm of Julius Springer published the first volume of Methods of Mathematical Physics by Richard Courant and David Hilbert. In the preface, Courant says this: Since the seventeenth century, physical intuition has served as a vital source for mathematical problems and methods. Recent trends and fashions have, however, weakened the connection between mathematics and physics; mathematicians, turning away from the roots of mathematics in intuition, have concentrated on refinement and emphasized the postulational side of mathematics, and at times have overlooked the unity of their science with physics and other fields. In many cases, physicists have ceased to appreciate the attitudes of mathematicians. This rift is unquestionably a serious threat to science as a whole; the broad stream of scientific development may split into smaller and smaller rivulets and dry out. It seems therefore important to direct our efforts toward reuniting divergent trends by clarifying the common features and interconnections of many distinct and diverse scientific facts. Only thus can the student attain some mastery of the material and the basis be prepared for further organic development of research. The present work is designed to serve this purpose for the field of mathe matical physics . . . . Completeness is not attempted, but it is hoped that access to a rich and important field will be facilitated by the book. When I was a student, the book of Courant and Hilbert was my bible. 312 pp. Englisch.
