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.

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 -Dynamic Programming is the analysis of multistage decision in the sequential mode. It is now widely recognized as a tool of great versatility and power, and is applied to an increasing extent in all phases of economic analysis, operations research, technology, and also in mathematical theory itself. In economics and operations research its impact may someday rival that of linear programming. The importance of this field is made apparent through a growing number of publications. Foremost among these is the pioneering work of Bellman. It was he who originated the basic ideas, formulated the principle of optimality, recognized its power, coined the terminology, and developed many of the present applications. Since then mathe maticians, statisticians, operations researchers, and economists have come in, laying more rigorous foundations [KARLIN, BLACKWELL], and developing in depth such application as to the control of stochastic processes [HoWARD, JEWELL]. The field of inventory control has almost split off as an independent branch of Dynamic Programming on which a great deal of effort has been expended [ARRoW, KARLIN, SCARF], [WIDTIN] , [WAGNER]. Dynamic Programming is also playing an in creasing role in modem mathematical control theory [BELLMAN, Adap tive Control Processes (1961)]. Some of the most exciting work is going on in adaptive programming which is closely related to sequential statistical analysis, particularly in its Bayesian form. In this monograph the reader is introduced to the basic ideas of Dynamic Programming. 160 pp. Englisch.…

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 -Existing works on stochastic processes belong to a field of abstract mathematics which puts them beyond the scope of the non-specialist. The preoccupations of research mathematicians being more often than not distant from the practical problems of experimental methodology, the needs of practical workers, though real, are not met by the majority of works that. deal with processes. By 'practical workers', we mean research scientists in all the different disciplines: Physics, Chemistry, Biology, Medicine, Population, Economics, Organisation, Operational Research etc. Indeed, all scientific research today touches upon complex fields in which deterministic models can be useful for no more than an element ary and simple approximation. The Calculus of Probability although offering some interesting models is still inadequate in many instances, particularly in the study of evolving systems. The practical worker must therefore have at his disposal a set of original and varied stochastic models. These models must not be too general, for in that case not only would their theoretical study prove difficult, but above all the adaptation of such models to an observed system would lead to an estimation of a great number of parameters on the basis of a necessarily restricted sample. This would constitute an insuperable difficulty for the practical scientist. It is therefore essential for him to have at his disposal a varied range of very characteristic models. 144 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This tutorial presents a hands-on introduction to a new discrete choice modeling approach based on the behavioral notion of regret-minimization. This so-called Random Regret Minimization-approach (RRM) forms a counterpart of the Random Utility Maximization-approach (RUM) to discrete choice modeling, which has for decades dominated the field of choice modeling and adjacent fields such as transportation, marketing and environmental economics. Being as parsimonious as conventional RUM-models and compatible with popular software packages, the RRM-approach provides an alternative and appealing account of choice behavior. Rather than providing highly technical discussions as usually encountered in scholarly journals, this tutorial aims to allow readers to explore the RRM-approach and its potential and limitations hands-on and based on a detailed discussion of examples. This tutorial is written for students, scholars and practitioners who have a basic background in choice modeling in general and RUM-modeling in particular. It has been taken care of that all concepts and results should be clear to readers that do not have an advanced knowledge of econometrics. 64 pp. Englisch. …

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In keeping with the general trend towards rationalisation, static calculations have of late also been programmed by electronic computers. The number of problems which can be advan tageously resolved in this way is, however, very limited as yet, partly on account of the relati vely high cost involved and partly due to the waiting time the statician must suffer after collect ing together his data and, finally, because the programming possibilities of the computer are limited. Nonetheless, if static calculations have to be rationalised, there is another way: all beam structures-whether they be continuous beams or frame constructions-are arithmetically based on individual spans which are freely supported or fixed at the ends. If the basic values for these can be ascertained quickly and accurately, then a considerable part of the arithmetical work is already done. It is the aim of this work to provide the statician with these values. An attempt has been made to deal as comprehensively as possible with all the cases of loading likely to arise in practice. Naturally, one case or another is bound to happen more frequently whilst others are seldom encountered. However, this allembracing programme is intended to make it possible for the user of this work, after a brief, familiarising period, always to use the same arithmetical pro cedure, the choice of the actual method being left to him. 120 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This is not an introduction to physics but an analysis of its founda tions. Indeed, the aims of this book are: (1) to analyze the form and content of some of the key ideas of physics; (2) to formulate several basic physical theories in an explicit and orderly (i. e. , axiomatic) fashion; (3) to exhibit their presuppositions and discuss some of their philosoph ical implications; (4) to discuss some of the controversial issues, and (5) to debunk certain dusty philosophical tenets that obscure the under standing of physics and hinder its progress. To the extent to which these goals are attained, the volume can serve as a companion to studies in theoretical physics aiming at deepening the understanding of the logical structure and the physical meaning of our science. In order to keep the book slender, whole fields of basic physical research had to be excluded - chiefly many-body physics, quantum field theories, and elementary particle theories. A large coverage was believed to be less important than a comparatively detailed analysis and reconstruction of three representative monuments: classical mechan ics, general relativity, and quantum mechanics, as well as their usually unrecognized presuppositions. The reader is invited to join the project and supply some of the many missing chapters - or to rewrite the present ones entirely. 328 pp. Englisch.…

In order to present a clear narrative I have omitted exact references to the literature for individual propositions. However, each chapter begins with a short introduction which also contains historical remarks. Deutsche Akademie der vVissenschaften zu Berlin Institut fur Reine Mathematik Albrecht Pietsch Foreword to the Second Edition Since the appearance of the first edition, some important advances have taken place in the theory of nuclear locally convex spaces. Firsts there is the Universality Theorem ofT. and Y. Komura which fully confirms a conjecture of Grothendieck. Also, of particular interest are some new existence theorems for bases in special nuclear locally convex spaces. Recently many authors have dealt with nuclear spaces of functions and distributions. Moreover, further classes of operators have been found which take the place of nuclear or absolutely summing operators in the theory of nuclear locally convex spaces. Unfortunately, there seem to be no new results on diametrai or approximative dimension and isomorphism of nuclear locally convex spaces. Since major changes have not been absolutely necessary I have restricted myself to minor additions. Only the tenth chapter has been substantially altered. Since the universality results no longer depend on the existence of a basis it was necessary to introduce an independent eleventh chapter on universal nuclear locally convex spaces. In the same chapter s-nuclear locally convex spaces are also briefly treated. 208 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -It is hardly an exaggeration to say that, if the study of general topolog ical vector spaces is justified at all, it is because of the needs of distribu tion and Linear PDE \* theories (to which one may add the theory of convolution in spaces of hoi om orphic functions). The theorems based on TVS \*\* theory are generally of the 'foundation' type: they will often be statements of equivalence between, say, the existence - or the approx imability -of solutions to an equation Pu = v, and certain more 'formal' properties of the differential operator P, for example that P be elliptic or hyperboJic, together with properties of the manifold X on which P is defined. The latter are generally geometric or topological, e. g. that X be P-convex (Definition 20. 1). Also, naturally, suitable conditions will have to be imposed upon the data, the v's, and upon the stock of possible solutions u. The effect of such theorems is to subdivide the study of an equation like Pu = v into two quite different stages. In the first stage, we shall look for the relevant equivalences, and if none is already available in the literature, we shall try to establish them. The second stage will consist of checking if the 'formal' or 'geometric' conditions are satisfied. 140 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In this second volume on the Foundations of Quantum Mechanics we shall show how it is possible, using the methodology presented in Volume I, to deduce some of the most important applications of quantum mechanics. These deductions are concerned with the structures of the micro systems rather than the technical details of the construction of preparation and registration devices. Accordingly, the only new axioms (relative to Volume I) which are introduced are concerned with the relationship between ensemble operators W, effect operators F, and certain construction principles of the preparation and registration devices. The applications described here are concerned with the measurement of atomic and molecular structure and of collision experiments. An additional and essential step towards a theoretical description of the preparation and registration procedures is carried out in Chapter XVII. Here we demonstrate how microscopic collision processes (that is, processes which can be describedby quantum mechanics) can be used to obtain novel preparation and registration procedures if we take for granted the knowledge of only a few macroscopic preparation and registration procedures. By clever use of collision processes we are often able to obtain very precise results for the operators Wand F which describe the total procedures from a very imprecise knowledge of the macroscopic parts of the preparation and regis tration processes. In this regard experimental physicists have done brilliant work. In this sense Chapter XVII represents a general theoretical foundation for the procedures used by experimental physicists. 436 pp. Englisch.…

Major scientific meetings, numerous publications and several post graduate courses on this subject have been presented during the past ten years. However, perusal of the literature will convince any critical reader of the need for a comprehensive presentation of lymphography in cancer. Funda mental knowledge of the anatomy and physiology of the lymphatic system, pharmacology of the contrast media, possible complications and in particular understanding of the clinical behaviour of malignant tumors place high demands on the physician. For this reason the personal experience of five authors and the most important data published in the literature have been compiled in this volume. It should give the reader up to date information on the indications for clinical lymphography and its interpretation, thereby de monstrating the limits of its diagnostic accuracy and stressing the great impor tance of the method for the evaluation of cancer patients. It has been a fortunate circumstance to draw on the experience of four distinguished contributors whose cooperation has enabled this attempt at a thorough coverage of clinical lymphography in cancer. 312 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The study of molecular collisions at energies from less than about 100 eV 3 down to a few 10- eV, which is roughly the range of chemical interest, has greatly expanded in the last 10 to 20 years. As in many fields, this activity has been stimulated by parallel advances in theory which have triggered the autocatalytic positive feedback system of experiment challenging theory and vice versa. Possibly the biggest driving force, however, has been the growing awareness that molecular collisions are important in our understanding of na tural and man-made environments. Molecular collision dynamics is now studied in connection with molecular formation in interplanetary space, upper atmo sphere chemistry, plasmas, lasers and fusion reactors, and is crucial for understanding gas-dynamic flow processes, gas-phase chemical reactions and catalysis. Despite the great strides made in studying elementary collisions in laboratory scattering experiments, many of the processes in these areas are too complicated for us to hope ever to study them in detail in the labo ratory. Thus in the long run we shall have to rely on theory. Initially, I think many of us, like myself, had hoped that the development of fast compu ters would outpace the demands on computing time so that 'brute force' quan tum-mechanical exact calculations would provide all the answers. Unfortunate ly this has not been the case and efficient approximations are needed. They can be broadly classified as classical, semiclassical or semiquantal. 248 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The applications of ergodic theory to metric number theory are well known; part of the latter theory turns out to be essentially a special case of general ergodic theorems. In the present book other applications of ergodic concepts are presented. Constructing 'flows' of integral points on certain algebraic manifolds given by systems of integral polynomials, we are able to prove individual ergodic theorems and mixing theorems in certain cases. These theorems permit asymptotic calculations of the distributions of integral points on such manifolds, and we arrive at results inaccessible up to now by the usual methods of analytic number theory. Typical in this respect is the theorem concerning the asymptotic distribution and ergodic behavior of the set of integral points on the sphere X2+ y2+z2=m for increasing m. It is not known up until now how to obtain the simple and geometrically obvious regularity of the distribution of integral points on the sphere other than by ergodic methods. Systems of diophantine equations are studied with our method, and flows of integral points introduced for this purpose turn out to be closely connected with the behavior of ideal classes of the corresponding algebraic fields, and this behavior shows certain ergodic regularity in sequences of algebraic fields. However, in this book we examine in this respect only quadratic fields in sufficient detail, studying fields of higher degrees only in chapter VII. 208 pp. Englisch.…
