Taschenbuch. Condizione: Neu. Neuware -The term 'function algebra' usually refers to a uniformly closed algebra of complex valued continuous functions on a compact Hausdorff space. Such Banach alge bras, which are also called 'uniform algebras', have been much studied during the past 15 or 20 years. Since the most important examples of uniform algebras consist of, or are built up from, analytic functions, it is not surprising that most of the work has been dominated by questions of analyticity in one form or another. In fact, the study of these special algebras and their generalizations accounts for the bulk of the re search on function algebras. We are concerned here, however, with another facet of the subject based on the observation that very general algebras of continuous func tions tend to exhibit certain properties that are strongly reminiscent of analyticity. Although there exist a variety of well-known properties of this kind that could be mentioned, in many ways the most striking is a local maximum modulus principle proved in 1960 by Hugo Rossi [RIl]. This result, one of the deepest and most elegant in the theory of function algebras, is an essential tool in the theory as we have developed it here. It holds for an arbitrary Banaeh algebra of £unctions defined on the spectrum (maximal ideal space) of the algebra. These are the algebras, along with appropriate generalizations to algebras defined on noncompact spaces, that we call 'natural func tion algebras'.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 256 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The aim of this paper is to show that the theory of jet bundles supplies the appropriate setting for the study of Backlund trans formations. These transformations are used to solve certain partial differential equations, particularly non-linear evolution equations. Of course jets have been employed for some time in the theory of partial differential equations, but so far little use has been made of them in applications. In the meanwhile, substantial progress has been made in the study of non-linear evolution equations. This work has been encouraged by the dis covery of remarkable properties of some such equations, for example the existence of soliton solutions and of infinite se quences of conservation laws. Among the techniques devised to deal with these equations are the inverse scattering method and the Backlund transformation. In our opinion the jet bundle formulation offers a unifying geometrical framework for under standing the properties of non-linear evolution equations and the techniques used to deal with them, although we do not consider all of these properties and techniques here. The relevance of the theory of jet bundles lS that it legitimates the practice of regarding the partial derivatives of field variables as independent quantities. Since Backlund trans formations require from the outset manipulation of these partial derivatives, and repeated shifts of point of view about which variables are dependent on which, this geometrical setting clari fies and simplifies the concepts involved, and offers the prospect of bringing coherence to a variety of disparate results.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 144 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -From the reviews: '.Here we have a book which we can wholeheartedly suggest. The mathematics is sound and pared to essentials; the examples are an impressive, well-chosen selection from the biomathematics literature, and the problem sets provide both useful exercises and some fine introductions to the art of modeling. Batschelet has written an introduction to biomathematics which is notable for its clarity - not only a clarity of presentation, but also a clarity of purpose, backed by a sure grasp of the field.' #Bulletin of Mathematical Biology#1 'For research workers in the biomedical field who feel a need for freshening up their knowledge in mathematics, but so far have always been frustrated by either too formal or too boring textbooks, there is now exactly what they would like to have: an easy to read introduction. This book is highly motivating for practical workers because only those mathematical techniques are offered for which there is an application in the life sciences. The reader will find it stimulating that each tool described is immediately exemplified by problems from latest publications.' #Int.

Taschenbuch. Condizione: Neu. Neuware -The problem to be considered here is the one faced by bargainers who must reach a consensus--i.e., a unanimous decision. Specifically, we will be consid ering n-person games in which there is a set of feasible alternatives, any one of which can be the outcome of bargaining if it is agreed to by all the bargainers. In the event that no unanimous agreement is reached, some pre-specified disagree ment outcome will be the result. Thus, in games of this type, each player has a veto over any alternative other than the disagreement outcome. There are several reasons for studying games of this type. First, many negotiating situations, particularly those involving only two bargainers (i.e., when n = 2), are conducted under essentially these rules. Also, bargaining games of this type often occur as components of more complex processes. In addi tion, the simplicity of bargaining games makes them an excellent vehicle for studying the effect of any assumptions which are made in their analysis. The effect of many of the assumptions which are made in the analysis of more complex cooperative games can more easily be discerned in studying bargaining games. The various models of bargaining considered here will be studied axioma- cally. That is, each model will be studied by specifying a set of properties which serve to characterize it uniquely.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 136 pp. Englisch.

Buch. Condizione: Neu. Neuware -With one exception, all of the papers in this volume were originally presented at a conference held in April, 1978, at The Ohio State University. The excep tion is the paper by Wilfrid Sellars, which is a revised version of a paper he originally published in the Journal of Philosophy, 1973. However, the present version of Sellars' paper is so thoroughly changed from its original, that it is now virtually a new paper. None of the other nine papers has been published previously. The bibliography, prepared by Nancy Kelsik, is very extensive and it is tempting to think that it is complete. But I believe that virtual com pleteness is more likely to prove correct. The conference was made possible by grants from the College of Human ities and the Graduate School, Ohio State University, as well as by a grant from the Philosophy Department. On behalf of the contributors, I want to thank these institutions for their support. I also want to thank Marshall Swain and Robert Turnbu~l for early help and encouragement; Bette Hellinger for assistance in setting up the confer ence; and Mary Raines and Virginia Foster for considerable aid in the pre paration of papers and many other conference matters. The friendly advice of the late James Cornman was also importantly helpful. April,1979 GEORGE S.

THE MACROMOLECULAR ELECTROSTATIC EFFECT IN BIOCHEMICAL ~EACTIVITY OF THE NUCLEIC ACIDS. BERNARD PULUIAN Institut de BioLogie Physico-Chimique, Laboratoire de Biochimie Theorique, aSSOCle au C. N. R. S. , 13, rue P. et M. Curie, Paris 75005, France. 1. INTRODUCTION The roLe of the macromoLecuLe and of its overaLL structure upon the reactivity of its reaction site(s) represents one of the fundamentaL probLems in the theory of cataLysis. The most impressive and most fre quentLy considered exampLes occur in the fieLd of proteins where the probLem generaLLy consists of accounting for the enhancement of the reaction rate at the active site or at the coenzyme with respect to modeL systems, devoid of the macromoLecuLar superstructure. Different effects have been considered as possibLy responsibLe for the infLuence of the macromoLecuLe on such LocaLized-site reactions. I do not have the time to summarize or discuss them here.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 404 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware - In the past few years, an increasing number of colleges and universities have added courses in biomedical ethics to their curricula. To some extent, these additions serve to satisfy student demands for 'relevance. ' But it is also true that such changes reflect a deepening desire on the part of the academic community to deal effectively with a host of problems which must be solved if we are to have a health-care delivery system which is efficient, humane, and just. To a large degree, these problems are the unique result of both rapidly changing moral values and dramatic advances in biomedical technology. The past decade has witnessed sudden and conspicuous controversy over the morality and legality of new practices relating to abortion, therapy for the mentally ill, experimentation using human subjects, forms of genetic interven tion, and euthanasia. Malpractice suits abound, and astronomical fees for malpractice insurance threaten the very possibility of medical and health-care practice. Without the backing of a clear moral consensus, the law is frequently forced into resolving these conflicts only to see the moral issues involved still hotly debated and the validity of the existing law further questioned. Take abortion, for example. Rather than settling the legal issue, the Supreme Court's original abortion decision in Roe v. Wade (1973), seems only to have spurred further legal debate. And of course, whether or not abortion is a mo rally ac ceptable procedure is still the subject of heated dispute.'.

Buch. Condizione: Neu. Neuware -E. Tengstrom G. Teleki The IAU symposium no 89, 'Refractional Influences in Astrometry and Geo desy' , was held at the University of Uppsala, Sweden, during August 1 through August 5, 1978. It was a joint meeting of IAU and lAG, cosponsor ed by lAG and IUGG. Considerable financial support was also given by the Swedish Natural Science Research Council, the Wallenberg Foundation in Stockholm and the University of Uppsala. The Scientific Organizing Committee included G. Teleki (chairman), W. Altenhoff (Bonn), P. Bender (Boulder), L. Hradilek (Prague), J.A. Hughes (Washington D.C.), J. Kakkuri (Helsinki), A.J. Nefedieva (Kazan), J. Saastamoinen (Ottawa), C. Sugawa (Mizusawa) and E. Tengstrom (Uppsala). The Local Organizing Committee included E. Tengstrom (chairman and con venor), I. Ohlsson (adm. secretary and treasurer), P. Hodacs, S-G. Martensson, S. Eklund and M. O'Shaughnessy, all from Up~sala. This symposium was the first international meeting of astronomers and geodesists connected with refraction phenomena. The proceedings of this symposium contain all papers accepted by its Scientific Organizing Committee, and all discussions around them to gether with all contributions during special workshops and round-table discussion programs.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 422 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The most general goal of this book is to propose and illustrate a program of research in word semantics that combines some of the methodology and results in linguistic semantics, primarily that of the generative semantics school, with the rigorously formalized syntactic and semantic framework for the analysis of natural languages developed by Richard Montague and his associates, a framework in which truth and denotation with respect to a model are taken as the fundamental semantic notions. I hope to show, both from the linguist's and the philosopher's point of view, not only why this synthesis can be undertaken but also why it will be useful to pursue it. On the one hand, the linguists' decompositions of word meanings into more primitive parts are by themselves inherently incomplete, in that they deal only in distinctions in meaning without providing an account of what mean ings really are. Not only can these analyses be made complete by a model theoretic semantics, but also such an account of these analyses renders them more exact and more readily testable than they could ever be otherwise.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 448 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Die Beta-Rezeptoren-Blockade hat sich als ein neues, sehr wirk sames Prinzip zur pharmakodynamischen Beeinflussung von Herz und Kreislauf erwiesen. Da sich gezeigt hat, daB dieses Prinzip bei ver schiedenen Erkrankungen des Herz-Kreislauf-Systems von praktischer Bedeutung sein konnte, wurden in letzter Zeit zahlreiche Substanzen synthetisiert, die eine betarezeptorenblockierende Wirkung entfalten. Das eingehende Studium dieser neuen Substanzen hat gezeigt, daB sie in ihrem Wirkungsspektrum recht verschieden sind. Es haben sich aufgrund der Wirkungsweise vier Gruppen von Substanzen heraus kristallisiert, namlich kardioselektive mit und ohne intrinsische Akti vitat sowie nicht kardioselektive mit und ohne intrinsische Aktivitat. Wahrend diese Substanzen sehr gut im Tierversuch experimentell getestet sind und auch einzelne Wirkungen beim Menschen eine genaue Analyse erfahren haben, so fehlen entsprechende Untersuchungen am Menschen, in denen das Zusammenspiel der gesamten Kreislauf regulation im gesunden und kranken Organismus analysiert worden ware. Es ist das groBe Verdienst Bonellis, dies en Mangel erkannt zu haben. Er hat nun versucht, durch systematische Untersuchungen die fehlenden 1nformationen beim Menschen zu sammeln. Er hat hierzu entsprechende Untersuchungen in Ruhe und unter korperlicher Be lastung, bei RechenstreB und Orthostase durchgefiihrt und hat die Wirkungen sowohl bei akuter als auch bei chronischer Verabreichung der Substanzen studiert. 1m dritten Abschnitt des vorliegenden Werkes wurde die Wirkung der einzelnen Gruppen von Betablockern bei hyperkinetischem Herzsyndrom, koronarer Herzkrankheit, StreB, orthostatischer Kreislaufregulationsstorung und Hypertonie eingehend untersucht.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 156 pp. Deutsch.

Taschenbuch. Condizione: Neu. Neuware -Noch vor ein bis zwei Jahrzehnten geniigten zum Medizinstudium die wiihrend der SchuIzeit erworbenen und in der Reifepriifung nachgewiesenen Mathematik Kenntnisse. Durch die Fortschritte der Physik und Technik, die in den verschiedenen Gebieten der Medizin ihren Niederschlag gefunden haben, sind jedoch die mathe matischen Anforderungen groBer geworden. Besonders in den drei folgenden Ge bieten kommt das zum Ausdruck: 1. Die funktionellen Grundfacher, von denen die Physiologie im Buch nur stell vertretend genannt worden ist, bediirfen zu ihrem Verstiindnis jetzt der Kenntnis elementarer Differentialgleichungen, Umgang mit Funktionen auch von mehreren Veriinderlichen sowie der Zuordnung von Formeln zu empirisch gefundenen Funktionsbildern. 2. Die medizinische Statistik hat durch die in den letzten Jahrzehnten von der modernen Stichprobenstatistik erarbeiteten Testverfahren gerade die meist kleineren Stichproben der Medizin aussagekriiftig gemacht. Hier sind zum Verstiindnis Grundbegriffe der Wahrscheinlichkeitsrechnung sowie das Rechnen mit Verteilungsfunktionen notwendig geworden. 3. Die medizinische Datenverarbeitung ist seit Einfiihrung automatisierter Dokumentationsverfahren, zuniichst der Maschinenlochkarten, und spiiter durch den Einsatz von elektronischen Anlagen (Computer) ebenfalls in aIle Bereiche der klinischen und theoretischen Medizin eingedrungen. Zum ver stiindnisvollen Einsatz gehOren einerseits gewisse Kenntnisse iiber Niiherungs verfahren zur Losung von Gleichungen, Integralen usw. sowie Kenntnisse zur logischen Algebra und Mengenlehre. Dariiber hinaus muB auch der Mediziner etwas iiber Maschinen-Codes und Programmiersprachen wissen.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 232 pp. Deutsch.

Taschenbuch. Condizione: Neu. Neuware -Die coronare Herzkrankeit stellt - neben dem 'vollen Magen' - das hochste Risiko fUr die Anaesthesie dar, wenn sie nicht behandelt oder - noch schwerwiegender - nicht erkannt wird. Coronare Herzkrankheit schrankt namlich die Reserven ein, die das gesunde Herz hat, urn selbst schwerwiegende Narkosebelastungen unbeschadet durchzustehen. Zumindest in unseren Breiten einer Uberflull. gesellschaft nimmt die Haufigkeit der coronaren Herzkrankheit stetig zu, relativ als Folge von seelischem Strell. und korperlichem Wohlleben, absolut als Folge der Erhohung des durchschnittlichen Lebensalters. So wird der Anaesthesist standig mehr mit dieser Erkrankung konfrontiert werden - und das nicht nur an den Zentren, wo die Chirurgie sie mit neuen Methoden wie der 'Coronarchirurgie' zu beherrschen ver sucht, wo also Patienten mit coronarer Herzkrankheit eigens zur Behandlung dieser Erkran kung anaesthesiert werden miissen. Eine sichere Narkose auch beim Schwerkranken wird nur derjenige Anaesthesist flihren kon nen, der die Schwere der Erkrankung erkennt, der urn ihre Ursachen weill. und der dariiber hinaus auch die Veranderungen, die seine Narkosemittel bei der bestehenden Krankheit am Patienten bewirken, kennt: welche von ihnen die Krankheit verschlechtern, welche sie verbes sern, welche sie unbeeinflull. t lassen. Haufig wird die Wirkung des Narkosemittels auf den kran ken Organismus als alleinige Ursache bei Zwischenfallen angeflihrt. Die Kunst des Anaesthe sisten besteht aber gerade darin, trotz ungiinstig wirkender Mittel den Patienten in jedem Fall wieder unbeschadet aufwachen zu lassen.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 112 pp. Deutsch.

Die Vorkommen sind geographisch breit ge streuti Entwicklungslander verfOgen darOber meist ebenso wie die groBen Industrie-Nationen. Die Erd61- und Erdgasvorkommen sind dagegen ein seitiger verteilt und voraussichtlich in wenigen Jahrzehnten ersch6pft. 1m Vergleich zu Mineral61 und Erdgas ist die Kohle aufwendiger zu gewinnen und in der Handhabung weniger bequem. I n den SOer und 60er Jahren bOBte die Kohle daher erhebliche Marktanteile zugunsten des Mineral61s und Erdgases ein. Durch die Entwicklungen der jOngsten Zeit hat die Kohle weltweit an Be deutung gewonnen. Es ware jedoch vermessen, die Preisentwicklung von Erd61 zahlenmaBi'g abzuschatzen und allein unter wirtschaftlichen Gesichts punkten den Zeitpunkt einer zunehmenden Resubstitution des Erd61s durch Kohle fixieren zu wollen. Die zukOnftige Energie-, Kraftstoff- und Rohstoffversorgung muB ausrei chend und langfristig gesichert sein, wobei gleichzeitig sowohl dem Ge sichtspunkt der Wirtschaftlichkeit als auch den Erfordernissen des Umwelt schutzes Rechnung zu tragen ist.
