Taschenbuch. Condizione: Neu. Neuware -The effect of calcium antagonists on heart muscle and blood circulation is the reason that they have found widespread clinical application for a number of years. Less well known, in contrast, is the effect this group of substances has on the kidneys, both on kidney cells and the blood flow through the kidneys. This effect was the subject of a workshop we organized in Tiibingen in June 1986. Different groups studied the effects of these substances, especially in animals, on the processing of calcium by the kidney cells and on blood flow. A possible explanation is that the calcium antagonists block the influx of calcium through special cell canals, especially the cells of the distal tubule. It is necessary to test whether there is a blockade or only a reduction in the passage of calcium. Our understanding of the effect of calcium antagonists is in large part based on the results of morphologic, physiologic, and pharmacologic studies of calcium in the kidneys. The particular processes involved in nephrocalcinosis are special objects of study with regard to calcium antagonists. This book presents the results of experimental studies of the effect of calcium antagonists on nephrocalcinosis and acute renal failure after ischemia. In this context, the clinician is particularly interested in the use of calcium antagonists to protect against the kidney in urolithiasis, in acute renal failure and during kidney transplantation. The book is thus of interest to urologists and nephrologists as well as pharmacologists. biochemists, physiologists, and others in research.…

Taschenbuch. Condizione: Neu. Neuware -In Part I of this report the pointwise derivation of scalar set functions is investigated, first along the lines of R. DE POSSEL (abstract derivation basis) and A. P. MORSE (blankets); later certain concrete situations (e. g. , the interval basis) are studied. The principal tool is a Vitali property, whose precise form depends on the derivation property studied. The 'halo' (defined at the beginning of Part I, Ch. IV) properties can serve to establish a Vitali property, or sometimes produce directly a derivation property. The main results established are the theorem of JESSEN-MARCINKIEWICZ-ZYGMUND (Part I, Ch. V) and the theorem of A. P. MORSE on the universal derivability of star blankets (Ch. VI) . . In Part II, points are at first discarded; the setting is somatic. It opens by treating an increasing stochastic basis with directed index sets (Th. I. 3) on which premartingales, semimartingales and martingales are defined. Convergence theorems, due largely to K. KRICKEBERG, are obtained using various types of convergence: stochastic, in the mean, in Lp-spaces, in ORLICZ spaces, and according to the order relation. We may mention in particular Th. II. 4. 7 on the stochastic convergence of a submartingale of bounded variation. To each theorem for martingales and semi-martingales there corresponds a theorem in the atomic case in the theory of cell (abstract interval) functions. The derivates concerned are global. Finally, in Ch. …

Taschenbuch. Condizione: Neu. Neuware -Die Entwicklung neuer Materialien und Techniken ftir die Gefäß chirurgie hat den Horizont der gesamten Chirurgie in ungeahnter Weise erweitert und befruchtet. Stand früher im wesentlichen die sachgemäße Versorgung von Gefäßen im Vordergrund, so bieten sich heute zahllose Möglichkeiten einer Rekonstruktion der Blut strombahn und darüber hinaus der Schaffung neuer Blutwege bis hin zum Anschluß transplantierter oder künstlicher Organe. Kein Zweig unseres Faches ist hiervon ausgeschlossen. Wenn sich auch besondere Schwerpunkte der Gefäßchirurgie entwickelt haben, so muß doch jeder Operateur zumindest die sein eigenes Interessen gebiet betreffenden Gefäßeingriffe beherrschen. Insofern mutet der hier und da geäußerte Alleinvertretungsanspruch ftir die gesamte Gefäßchirurgie kurios an. Viele Chirurgen sind von dieser stürmischen Entwicklung über holt worden, während andere mangels Weiterbildungsmöglichkei ten oder eines geeigneten Krankengutes Mühe haben, diesen Fort schritt mitzuvollziehen. Diese Hemmnisse zu überwinden, hat sich der Autor ausdrücklich zum Ziel gesetzt. Die Gefäßchirurgie -wie jede andere operative Tätigkeit -steht auf drei Säulen. Einmal muß der gegenwärtige Stand des Wissens über die Möglichkeiten und Grenzen der Gefäßchirurgie vorhan den sein. Dann gilt es, die im Grunde einfachen, wenn auch durch besondere Sorgfaltspflicht gezeichneten Methoden der atraumati schen Handhabung von Gefäßen und deren Naht zu erlernen und schließlich muß der Zugriff zum Gefäßsystem 'sitzen', das heißt, eindeutig, zweckmäßig und schonend sein. Diesem letzteren Ziel dient dieses Werk.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 164 pp. Deutsch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book presents a methodological framework for the analysis of intercultural issues frequently misinterpreted by existing theories. It uses a challenge-and-response theory of cultural development to examine the relationship between different natural disasters and threats and the developments of ancient civilizations. The spatial interaction of ancient civilizations is assessed; and four non-linear patterns of intercultural dynamics are presented. Our empirical analyses of the four major ancient civilizations (the Mesopotamian, the Egyptian, the Indus, and the Chinese) focus on intercultural influences as well as how they have shaped the spatial dynamics of the world as a whole.This book also examines various aspects of intercultural economic influences, such as those of culture on international trade. Evidence from a broad panel of nations supports the presumption that high-income trade partners will be less sensitive to the measures of cultural dissimilarity than low-income trade partners between which cultural dissimilarity leads to barriers to international trade. The treatment of linguistic and religious factors as continuous variables in this book has improved past studies in which 'language' was treated as one or more dummy variables and 'religion' was ignored. 116 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Low-temperature spectroscopy of organic molecular crystals came into being in the late 20s, just when quantum physics of solids as a whole began to de velop vigorously. Already in the early works, two experimental facts of prime importance were discovered: the presence of a multitude of narrow bands in the low-temperature spectrum of a crystal, and a close relationship between the spectrum of the crystal and that of the constituent molecules. These findings immediately preceded the celebrated paper of Frenkel in which he went beyond the framework of Bloch's scheme and advanced the exciton concept. Subsequent investigations showed that the most interesting features of the spectra of molecular crystals are associated with excitons, and then the spectroscopy of molecular excitons began to form gradually on the basis of the spectroscopy of organic crystals. The molecular exciton became synonymous to the Frenkel exciton in a molecular crystal. In view of the difficulties involved in the analysis of rich spectra con taining many tens of bands, the spectroscopy of molecular crystals had long been connected most closely with the spectroscopy of molecules. It had deve loped independently, to a large extent, from the other branches of solid state physics. This was also emphasized by the difference in experimental techniques, the specific properties of the objects, etc. As a result, there was some lag in ideas and concepts. 288 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The basic idea, simple and revolutionary at the same time, to replace the concept of a point particle with a one-dimensional string, has opened up a whole new field of research. Even today, four decades later, its multifaceted consequences are still not fully conceivable. Up to now string theory has offered a new way to view each particle: as different excitations of the same fundamental object. It has celebrated success in discovering the graviton in its spectrum, and it has naturally led scientists to posit space-times with more than four dimensions-which in turn has triggered numerous interesting developments in fields as varied as condensed matter physics and pure mathematics.This book collects pedagogical lectures by leading experts in string theory, introducing the non-specialist reader to some of the newest developments in the field. The carefully selected topics are at the cutting edge of research in string theory and include new developments in topological strings, or AdS/CFT dualities, as well as newly emerging subfields such as doubled field theory and holography in the hydrodynamic regime.The contributions to this book have been selected and arranged in such a way as to form a self-contained, graduate level textbook. 308 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -For some time now, I have felt that the time is right to write a book about Computer Chess. Ever since the first attempts at chess pro gramming were made, some twenty five years ago, interest in the subject ha's grown from year to year. During the late 1950s the subject was first brought to the attention of the public by an article in Scient(fic American, and less than a decade later a chess program was competing in a tournament with humans. More recently, there have been tournaments in which the only participants were computer programs. and when the first World Computer Championship was held in Stockholm in 1974 the event was an outstanding success. Laymen often doubt the value of investing in a subject so esoteric as computer chess, but there is definitely considerable benefit to be gained from a study of the automisation of chess and other intellectual games. If it proves possible to play such games well by computer, then the techniques employed to analyse and assess future positions in these games will also be useful in other problems in long-range planning. I have tried to make this book both interesting and instructive. Those who understand anything at all about chess but who have no knowledge of computers, will be able to follow my description of how computers play chess. Those with a knowledge of both areas will still find much to interest them. 316 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The point of departure of this general survey of modern structural linguistics is the place of language in human relations. Linguistics will consequently be understood as a science of communication. My book is not intended as an elementary handbook. The readers are supposed to be in the first place advanced students of linguistics and phonetics and of neighbouring fields where a real awareness of linguistic methods and problems is essential (such as psychology, phoniatrics, speech therapy, language teaching, communication engineering). The book may, however, be of some value also for the general reader who is interested in language, in language learning, or in communication processes. It might finally serve as an introduction to structural theories and practice for those linguists of traditional orientation who would like to make contact with the new trends in the study of language. It is self-evident that, under such circumstances, any reader will find certain chapters in this book rather complicated, others irritatingly elementary. This is, however, unavoidable in a work whose aim is to cover a vast field of knowledge and to offer the reader a synthesis of what appears at first sight to be widely disparate facts and phenomena. Many of the facts brought together here may, regarded superficially, seem to have few or no mutual connections. They can, nevertheless, be combined into a wide humanistic and scientific unity within which numerous lines of relationship bind together physical and psychic, individual and social phenomena. 224 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Except for this preface, this study is completely self-contained. It is intended to serve both as an introduction to Quantification Theory and as an exposition of new results and techniques in 'analytic' or 'cut-free' methods. We use the term 'analytic' to apply to any proof procedure which obeys the subformula principle (we think of such a procedure as 'analysing' the formula into its successive components). Gentzen cut-free systems are perhaps the best known example of ana lytic proof procedures. Natural deduction systems, though not usually analytic, can be made so (as we demonstrated in [3]). In this study, we emphasize the tableau point of view, since we are struck by its simplicity and mathematical elegance. Chapter I is completely introductory. We begin with preliminary material on trees (necessary for the tableau method), and then treat the basic syntactic and semantic fundamentals of propositional logic. We use the term 'Boolean valuation' to mean any assignment of truth values to all formulas which satisfies the usual truth-table conditions for the logical connectives. Given an assignment of truth-values to all propositional variables, the truth-values of all other formulas under this assignment is usually defined by an inductive procedure. We indicate in Chapter I how this inductive definition can be made explicit-to this end we find useful the notion of a formation tree (which we discuss earlier). 176 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Advances which have been made in the field of lipid chemistry and bio chemistry during the last ten years mainly are the results of progress in metho dology. The introduction of isotopic and chromatographic techniques has not only enriched our knowledge of normal lipid metabolism but has also greatly enhanced the understanding of the various lipidoses. This is well illustrated by a comparison of the contents of the present monograph with those of my 1955 review in Handbuch der Inneren Medizin (Springer). In addition to better information about the classic lipid thesaurismoses Nie mann-Pick disease, Gaucher's disease and Tay-Sachs disease, the number of hereditary lipid storage diseases has increased considerably through the recogni tion of new syndromes such as metachromatic leukodystrophy, Fabry's disease, Refsum's disease (heredopathia atactica polyneuritiformis), a-p-lipoproteinemia, and Tangier disease. Conversely, disorders such as Hand-Scholler-Christian disease which has been considered a lipidosis up to 1958 (THANNHAUSER) must now be differentiated from the hereditary disturbances of lipid metabolism. Essential hyperlipemia which at one time seemed to be a well defined entity has now been recognized to consist of a number of subgroups, whose pathogeneses appear to be quite different, and whose classification is by no means definite. Similar problems exist for 'essential hypercholesterolemia'. Since the knowledge of today is the key for the solutions of tomorrow, we are fortunate that the chapters on lipidoses are supplemented by a comprehensive account of lipid chemistry and biochemistry which has been coordinated by W. STOFFEL. 644 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Theoretical researches in general relativity and observational data from galactic astronomy combine in this volume in contributions to one of the oldest questions of natural philosophy: Is the structure of the physical world more adequately described by a continuous or a discrete mode of representation Since the days of the Pythagoreans, this question has surfaced from time to time in various guises in science as well as in philosophy. One of the most bitterly contested and illuminating controversies between the continuous and the discrete viewpoints is to be found in the wave versus corpuscular description of optical phenom enae. This controversy was not resolved to the satisfaction of most of its protaganists until the development of the quantum theory. However, several obscurities that still becloud the question suggest that some deeper formulation may be necessary before more satisfactory answers can be given 1. The firm establishment of the validity of quantized structure and discrete energy distributions on the atomic scale following the ideas of Max Planck, together with the apparent absence of quan tization effect in astronomical and cosmic structures leaves uncertainties concerning the role played by the scale of the observer in perceiving or not perceiving discrete distributions. Some of the metaphysical inter pretations and implications of the quantum mechanics that have been made in recent years 2 would be subject to revision if the existence of discretized descriptions were to be established in astronomical and cosmic structures. 200 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The present volume gives a systematic treatment of potential functions. It takes its origin in two courses, one elementary and one advanced, which the author has given at intervals during the last ten years, and has a two-fold purpose: first, to serve as an introduction for students whose attainments in the Calculus include some knowledge of partial derivatives and multiple and line integrals; and secondly, to provide the reader with the fundamentals of the subject, so that he may proceed immediately to the applications, or to the periodical literature of the day. It is inherent in the nature of the subject that physical intuition and illustration be appealed to freely, and this has been done. However, that the book may present sound ideals to the student, and in order also serve the mathematician, both for purposes of reference and as a basis for further developments, the proofs have been given by rigorous methods. This has led, at a number of points, to results either not found elsewhere, or not readily accessible. Thus, Chapter IV contains a proof for the general regular region of the divergence theorem (Gauss', or Green's theorem) on the reduction of volume to surface integrals. The treatment of the fundamental existence theorems in Chapter XI by means of integral equations meets squarely the difficulties incident to the discontinuity of the kernel, and the same chapter gives an account of the most recent developments with respect to the Dirichlet problem. 400 pp. Englisch.…

This book presents the results of experimental studies of the effect of calcium antagonists on nephrocalcinosis and acute renal failure after ischemia. In this context, the clinician is particularly interested in the use of calcium antagonists to protect against the kidney in urolithiasis, in acute renal failure and during kidney transplantation. The book is thus of interest to urologists and nephrologists as well as pharmacologists. biochemists, physiologists, and others in research. 204 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In Part I of this report the pointwise derivation of scalar set functions is investigated, first along the lines of R. DE POSSEL (abstract derivation basis) and A. P. MORSE (blankets); later certain concrete situations (e. g. , the interval basis) are studied. The principal tool is a Vitali property, whose precise form depends on the derivation property studied. The 'halo' (defined at the beginning of Part I, Ch. IV) properties can serve to establish a Vitali property, or sometimes produce directly a derivation property. The main results established are the theorem of JESSEN-MARCINKIEWICZ-ZYGMUND (Part I, Ch. V) and the theorem of A. P. MORSE on the universal derivability of star blankets (Ch. VI) . . In Part II, points are at first discarded; the setting is somatic. It opens by treating an increasing stochastic basis with directed index sets (Th. I. 3) on which premartingales, semimartingales and martingales are defined. Convergence theorems, due largely to K. KRICKEBERG, are obtained using various types of convergence: stochastic, in the mean, in Lp-spaces, in ORLICZ spaces, and according to the order relation. We may mention in particular Th. II. 4. 7 on the stochastic convergence of a submartingale of bounded variation. To each theorem for martingales and semi-martingales there corresponds a theorem in the atomic case in the theory of cell (abstract interval) functions. The derivates concerned are global. Finally, in Ch. 216 pp. Englisch.…
