Buch. Condizione: Neu. Neuware - The purpose of this volume and Pediatric Nephrology Seminar IX from which it was created is to provide easy access to current concepts in the diagnosis and management of kidney diseases in the newborn. Complimentary to this purpose is the opportunity the Seminar structure gives me to invite those particularly interested in the subject chosen to come together, share experiences and ideas in an unhurried, unpressured atmosphere for four con tinuous days - an oasis for me and, I am told, also for the faculty and registrants. This year's subject choice is an expression of my perennial interest in the kidney of the newborn. A step back to view the steps forward reveals unwittingly intertwined associations and actions which now fall into focus. When I was just beginning my pediatric nephrology training with Sol Kaplan at Downstate in Brooklyn, we discussed Bob Usher's pioneering thought that there was something wrong with the kidneys of babies with RDS. Without really knowing what needed to be done, I started looking at the kidneys of those babies. Subsequently, Dick Day who was Chairman of the Department of Pedia trics there, stopped me in the hall, and asked me to come into his office. Glowing in quiet introspection, he extolled the joy of working with one's hands, then hurried away to his laboratory. He had been the Director of the Newborn Nursery at Babies Hospital before coming to Downstate, and (as I later found out) was trying to do something with oxygen electrodes.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The Handbook of Hospital Medicine was originally conceived by Dr Mitchell as a guide for junior medical staff working in his own unit. Its aim was to provide a practical pocket-sized guide on diagnosis, investigation, and general management of some of the more common medical problems. The success of the original book in Dr Mitchell's unit lead to its introduction in other units and hospitals and through the help of Johnson and Johnson to junior hospital doctors throughout South Africa. We (PNP and CW) have taken Dr Mitchell's original book and have attempted to modify it to the needs of medicine in Britian. The basic concept of the book remains the same, i.e. to provide a practical pocket reference guide for final year medical students through to registrars. Within the limits imposed by a pocket book it is obviously impossible to be comprehensive. We have attempted to cover common problems, but have also covered some less common cionditions we considered important, or where we felt rapid referrence was not readily available. The views presented represent an up-to date consensus of thinking, which we have had to present in a rather dogmatic form due to the constraints of space. We have given details of drug doses in the book but have assumed that the British National Formulary will be readily available for reference on drug side-effects and interactions. We would like to acknowledge the help and advice of many colleagues in the Newcastle area hospitals. 192 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -THE VOICE OF THE PEOPLE: THE POLISH ROAD FROM SOCIALISM ON 1. The history of all hitherto existing societies is a history of class struggle - not only that between the exploited and the exploiters, but also that between the ruled and the rulers. And in modern times, there is in some societies a struggle between those who are exploited and oppressed at the same time and those who at the same time exploit and oppress. 2. The struggle between the owners and the direct producers results from the fact that the former exploit the latter, that is, they take from their labour more than they give back. It is possible since only they, the exploiters, have a monopoly of the disposal over the m~ans of production, and the major part of society must provide them with their labour force. Increasing exploitation finally leads to the revolution of the masses -and the owners are forced to make concessions in order to avoid re-occurrences. 416 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Semi-infinite programming is a natural extension of linear pro gramming that allows finitely many variables to appear in infinitely many constraints. As the papers in this collection will reconfirm, the theoretical and practical manifestations and applications of this prob lem formulation are abundant and significant. This volume presents 20 carefully selected papers that were pre sented at the International Symposium on Semi-Infinite Programming and Applications, The University of Texas at Austin, September 8-10, 1981. A total of 70 papers were presented by distinguished participants from 15 countries. This was only the second international meeting on this topic, the first taking place in Bad Honnef,Federal Republic of Germany in 1978. A proceedings of that conference was organized and edited by Rainer Hettich of the University of Trier and published by Springer Verlag in 1979. The papers in this volume could have been published in any of several refereed journals. It is also probable that the authors of these papers would normally not have met at the same professional society meeting. Having these papers appear under one cover is thus something of a new phenomenon and provides an indication of both the unification and cross-fertilization opportunities that have emerged in this field. These papers were solicited only through the collective efforts of an International Program Committee organized according to the fol lowing research areas. 340 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This short book attempts to give a reader who has a basic biochemical and microbiological background (one to two years at University level) an idea of the ecological, biochemical, physiological and biotechnological importance of methane, methanol and related compounds in the microbial world. Because the book covers several different scientific disciplines, readers may encounter unfamiliar terminology. The glossary at the end of the book defines the more obscure of these. The book has been written during a period of heavy teaching commit ments, and despite the helpful comments of many colleagues, it is likely that errors have crept in. As I have no co-author whom I can blame, I must accept sole responsibility for these! I wish to thank the many friends, students and colleagues who have read all or part of the manuscript: Charlie Bamforth, Rick Gibson, Jeff Green, Theo Hansen, Wim Harder, Geoff Haywood and, above all, Hans van Dijken. 100 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The first edition of this book was received more kindly than it deserved by some, and with some scepticism by others. It set out to present a simple, concise and reasonably comprehensive introduction to some of the theoretical and empirical criteria which may be used to define rock as a structural material. The objectives - reinforced by the change in title - remain the same, but the approach has been changed considerably and only one or two sections have been retained from the first edition. The particular aim in this edition is to provide a description of the mechanical behaviour of rocks, based firmly upon experimental data, which can be used to explain how rocks deform, fracture and yield, and to show how this knowledge can be used in design. The major emphasis is on the behaviour of rocks as materials, although in the later chapters the behaviour of discontinuities in rocks, and the way in which this can affect the behaviour of rock masses, is considered. If this edition is an improvement on the first edition it reflects the debt lowe to numerous people who have attempted to explain the rudiments of the subject to me. I should like to thank Peter Attewell and Roy Scott in particular. I should also like to thank Tony Price and Mike Gilbert whose work at Newcastle I have used shamelessly. 220 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In the sixth edition of this work John Fry has reverted to the format of the earlier editions published in 1965, 1970 and 1973 and has presented statistical data drawn widely from many sources. General practice in the United Kingdom and elsewhere throughout the world has undergone many changes in the past decade. This new edition brings the available statistical informa tion up to date and indicates the way ahead. General practice, the College and the National Health Service have been closely linked in effecting change. The membership of the College con tinues to grow and its influence in changing the face of general practice in the United Kingdom is significant. John Fry's new book presents that characteristic blend of fact and personal opinion which was so successful in earlier editions and so valuable to general practice and others in primary health care. Once again he has shown what can be achieved by one man based on his own work and those of others in general practice. John Lawson RCGP, 1983 President of the Royal College of General Practitioners vi Preface The Present State and Future Needs series had its roots in the dark days of the early 1960s when morale in general practice was low and when numbers of new entrants were actually going down. They were the days of mass emigration of doctors from Britain and the National Health Service. The fourth and fifth editions were entitled Trends in General Practice (1977 and 1979). 100 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -These lectures were prepared by the authors for Seminars to be held on June 6, 1983, in St.Louis, Missouri, under the spon sorship of the Radiopharmaceutical Science Council of the So ciety of Nuclear Medicine . All manuscript were refereed . Tracer kinetics and the modeling of physiological and bio chemical processes in vivo are the focus of a contemporary di rection in biochemical research. Recent advances in instrumen tation (especially positron emission tomography and digital autoradiography) and parallel developments in the production of short-lived radionuclides and rapid synthetic chemistry to pre pare tracers that probe metabolism, flow, receptor-ligand kinetics, etc., are responsible for new scientific frontiers. These developments, coupled with biomathematics and computer science, make it possible to quantitatively evaluate tracer kinetic models in animals and man. (The choice of animal models in radiotracer design and tracer kinetics is the subject of a book edited by R.M.Lambrecht and W.C.Eckleman in press at Sprin ger Verlag.) Tracer kinetics and physiological modeling is truly multi disciplinary, as evidenced by the intellectual diversity and international representation observable in the list of contri butors . The lectures outline and attempt to show the transition from the theoretical description to the practical application of modeling for understanding normal and pathological processes . 524 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This text is intended to serve as an introduction to the geometry of the action of discrete groups of Mobius transformations. The subject matter has now been studied with changing points of emphasis for over a hundred years, the most recent developments being connected with the theory of 3-manifolds: see, for example, the papers of Poincare [77] and Thurston [101]. About 1940, the now well-known (but virtually unobtainable) Fenchel-Nielsen manuscript appeared. Sadly, the manuscript never appeared in print, and this more modest text attempts to display at least some of the beautiful geo metrical ideas to be found in that manuscript, as well as some more recent material. The text has been written with the conviction that geometrical explana tions are essential for a full understanding of the material and that however simple a matrix proof might seem, a geometric proof is almost certainly more profitable. Further, wherever possible, results should be stated in a form that is invariant under conjugation, thus making the intrinsic nature of the result more apparent. Despite the fact that the subject matter is concerned with groups of isometries of hyperbolic geometry, many publications rely on Euclidean estimates and geometry. However, the recent developments have again emphasized the need for hyperbolic geometry, and I have included a comprehensive chapter on analytical (not axiomatic) hyperbolic geometry. It is hoped that this chapter will serve as a 'dictionary' offormulae in plane hyperbolic geometry and as such will be of interest and use in its own right. 356 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book was written during a period when the technologies of genetic engineering were being applied to the study of animal viruses and when the organization and function of individual virus genes were being elucidated. This book, which uses human and animal viruses as models, aims to under stand the developments in molecular virology during the last 20 years. Al though molecular virology could also be taught by means of bacteriophages or plant viruses, the advantage of using animal viruses is in their ability to cause human and animal diseases as well as to transform cells, a primary problem in medicine. For the sake of clarity and convenience, not all the individual contributors to the various aspects of molecular virology were cited in the text. Instead, the reader is referred to review articles or key papers that list the numerous excel lent publications that have contributed to clarification of the various molecular processes. Thus the end-of-chapter bibliographies will guide the reader to the publications in which the original contributing authors are quoted. References given under the heading Recommended Reading are intended to assist those interested in pursuing a given subject further. I hope that this book will fulfill the purpose for which it is designed, and I urge readers to contact me if errors are found or updating is required. 356 pp. Englisch.

The conference was performed by the interest group 'Computer Net w 0 r k s ' j us t founded by the co mm itt e e 3/4 of the G e sell s c h aft fUr Informatik (GI) and the committees 6, 9, and 12 of the Nachrichten technische Gese11schaft (NTG). It was hosted by the Deutsche For sChungs- und Versuchsansta1t fUr Luft- und Raumfahrt at Cologne. The idea of the conference was to bring together experts from satel lite communication research and development, from telecommunication authorities and from the user community. The fast evolution of sa tellites designed to be used for new data communication services in fluences the necessity to exchange the present knowledge on chances, challenges, and problems of future satellite based data communication systems and services. Within this young te1ematics discipline only few groups in Europe can report on extensive experiences. Therefore we are glad that some of the most advanced activities and plans in Europe could be presented here at their current status. Some rather valuable information has been transferred during the in tensive discussions, and we try to summarize some important aspects of each session within the volume in hand. 264 pp. Englisch.
