Buch. Condición: Neu. Neuware -The purpose of this book is to give a systematic development of differential and integral calculus for functions of several variables. The traditional topics from advanced calculus are included: maxima and minima, chain rule, implicit function theorem, multiple integrals, divergence and Stokes's theorems, and so on. However, the treatment differs in several important respects from the traditional one. Vector notation is used throughout, and the distinction is maintained between n-dimensional euclidean space En and its dual. The elements of the Lebesgue theory of integrals are given. In place of the traditional vector analysis in £3, we introduce exterior algebra and the calculus of exterior differential forms. The formulas of vector analysis then become special cases of formulas about differential forms and integrals over manifolds lying in P. The book is suitable for a one-year course at the advanced undergraduate level. By omitting certain chapters, a one semester course can be based on it. For instance, if the students already have a good knowledge of partial differentiation and the elementary topology of P, then substantial parts of Chapters 4, 5, 7, and 8 can be covered in a semester. Some knowledge of linear algebra is presumed. However, results from linear algebra are reviewed as needed (in some cases without proof). A number of changes have been made in the first edition. Many of these were suggested by classroom experience. A new Chapter 2 on elementary topology has been added.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 428 pp. Englisch.

Buch. Condición: Neu. Neuware -This fourth edition contains several additions. The main ones con cern three closely related topics: Brownian motion, functional limit distributions, and random walks. Besides the power and ingenuity of their methods and the depth and beauty of their results, their importance is fast growing in Analysis as well as in theoretical and applied Proba bility. These additions increased the book to an unwieldy size and it had to be split into two volumes. About half of the first volume is devoted to an elementary introduc tion, then to mathematical foundations and basic probability concepts and tools. The second half is devoted to a detailed study of Independ ence which played and continues to playa central role both by itself and as a catalyst. The main additions consist of a section on convergence of probabilities on metric spaces and a chapter whose first section on domains of attrac tion completes the study of the Central limit problem, while the second one is devoted to random walks. About a third of the second volume is devoted to conditioning and properties of sequences of various types of dependence. The other two thirds are devoted to random functions; the last Part on Elements of random analysis is more sophisticated. The main addition consists of a chapter on Brownian motion and limit distributions.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 448 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -Vor rund 350 Millionen Jahren dürfte die Klasse der Chondrichthyes entstanden sein, deren bekannteste Vertreter die modernen Haie sind. Die Untersuchung ihrer Morpho logie erscheint interessant, weil sie einen Konstruktionszustand repräsentieren, der die Grundlage für das Verständnis von Phylogenie und Ontogenie vieler Wirbeltiere bildet. Bei der Erforschung des funktionellen Baues des cranialen Skelettes haben deshalb schon um die Jahrhundertwende Tiesing (1896), Sewertzoff (1899) und Luther (1908/ 1909) auf die Ordnung der Selachier zurückgegriffen. Leider gingen diese ersten An sätze wie auch die Arbeiten von Garman (1913), Daniel (1915) und Graf Haller (1926) über Beschreibungen und Vergleiche kaum hinaus. Beim Menschen unternahmen zu nächst Weigele (1921) und Richter (1921), später auch Molitor (1969) und Küppers (1971) den Versuch, mechanische Gesetzmäßigkeiten im Bau des Unterkiefers aufzu finden. Doch erst 1963 gelang es Crompton und Parkyn, die von säugetierähnlichen Reptilien ausgingen, allgemeine Regeln der Statik auf die Unterkieferentwicklung bei den Säugetieren zu übertragen. Sie kamen zu dem Schluß, daß in der Entwicklungs reihe zu den Säugetieren zwei Tendenzen eine wichtige Rolle spielen: die fortschrei tende Gelenkentlastung und die effektivere Ausnutzung der Muskelkraft durch Anlage eines längeren Hebelarmes. Alexander (1968) beschäftigte sich allgemein mit Tierme chanik und widmete dem Gebiet der Unterkieferstatik bei Säugetieren einige Kapitel, wobei er hauptsächlich auf Crompton (1963) zurückgriff. Alle diese Untersuchungen beschäftigen sich rein theoretisch hauptsächlich mit der Kaumuskulatur, deren Zug richtung, deren Hebelarmen und der sich daraus ergebenden mechanischen Beanspru chung des Kiefers.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 60 pp. Deutsch.

Taschenbuch. Condición: Neu. Neuware -Die heutige Hautklinik hat nur noch sehr wenig vom Zuschnitt der 'Schmierdermatologie' vor und während des letzten Weltkrieges. Naturgemäß wird die externe Behandlung immer ihren Wert behal ten, aber sie steht nicht mehr ausschließlich im Mittelpunkt. Revo lutionierend haben in der Dermato-Venerologie die Antibiotica, die Antihistaminica, die Corticosteroide und zuletzt die Cytostatica ge wirkt. Letztere sind nicht mehr aus dem täglichen Arzneischatz des Hautfacharztes wegzudenken. Ihre weitere Entwicklung vollzieht sich jedoch fast explosionsartig -, und es ist für den Hautfacharzt nicht ganz leicht, hier die Übersicht zu behalten. Bisher fehlte ein handliches Buch mit konzisem Text für die tägliche Praxis, das die Anwendung der Cytostatica in der Dermatologie klar verständlich abhandelt. Es ist das Verdienst des Verfassers, das pharmakologisch schwierige Gebiet der Cytostatica und speziell deren Einsatz bei der Behandlung von Hautkrankheiten in gut lesbarer Form dargestellt zu haben. Die Ausführungen sind nicht als Handbuchartikel mit überdimensionalem Literaturverzeichnis gedacht, sondern wenden sich hauptsächlich an den praktisch tätigen oder den in der Klinik arbeitenden Dermatologen. Man spürt das Bestreben des Autors, einen sinnvollen Gebrauch der Cytostatica in unserem Fach zu för dern - aber auch auf ihre Gefahren aufmerksam zu machen. In der deutschen wissenschaftlichen Literatur fehlte ein solches Buch bis jetzt, und dies, obwohl Cytostatica als Immunosuppressiva nicht nur in den Kliniken, sondern auch in den Fachpraxen häufig verordnet werden. Schon aus diesem Grunde wünsche ich dem Buch eine weite Verbreitung.

This item is printed on demand - it takes 3-4 days longer - Neuware -The modern development of medicine has been characterized by the grow ing use of new technologies in health care delivery and research. As an empirical science, medicine is based on many types and quantities of information to recognize alterations, explore causes and apply cor rective action. Dealing with biological objects, signals have to be collected, processed and interpreted to recognize the state of this object. It is therefore understandable that data processing technology and informatics have been employed to a growing extent in medicine. The increasing economic repercussions of modern medicine lead also to the demand of ways and means to assess the system as such and to develop means for evaluation and regulation. However, the application of data processing to the medical field has very often grown in parallel to and remote from the development of in formatics and data processing in general. Furthermore, difficulties have occurred resulting from the differing concepts of reasoning, deci sion making and methodology. We therefore decided to start a series of seminars with the attempt to bring scientists from both medicine and informatics together to discuss basic principles of informatics and medicine and to attempt a synthesis between the problems in medicine and health care delivery and methods in informatics to approach a solu tion of these problems. This volume contains the lecture notes of the first seminar of this type. 724 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The nature and function of language as Man's chief vehicle of communi cation occupies a focal position in the human sciences, particularly in philosophy. The concept of 'communication' is problematic because it suggests both 'meaning' (the nature of language) and the activity of speaking (the function of language). The philosophic theory of 'speech acts' is one attempt to clarify the ambiguities of 'speech' as both the use of language to describe states of affair and the process in which that description is generated as 'communication'. The present study, Speech Act Phenomenology, is in part an exam ination of speech act theory. The theory offers an explanation for speech performance, that is, the structure of speech acts as 'relationships' and the content of speech acts as 'meaning'. The primary statement of the speech act theory that is examined is that presented by Austin. A seconda ry concern is the formulation of the theory as presented by Searle and Grice. The limitations of the speech act theory are specified by applying the theory as an explanation of 'human communication'. This conceptual examination of 'communication' suggests that the philosophic method of 'analysis' does not resolve the antinomy of language 'nature' and 'function'. Basically, the conceptual distinctions of the speech act theory (i. e. locutions, illocutions, and perlocutions) are found to be empty as a comprehensive explanation of the concept 'communication'. 148 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -When I was asked to help organize an American Association for the Advancement of Science symposium about how mathematical models have con tributed to biology, I agreed immediately. The subject is of immense importance and wide-spread interest. However, too often it is discussed in biologically sterile environments by 'mutual admiration society' groups of 'theoreticians', many of whom have never seen, and most of whom have never done, an original scientific experiment with the biolog ical materials they attempt to describe in abstract (and often prejudiced) terms. The opportunity to address the topic during an annual meeting of the AAAS was irresistable. In order to try to maintain the integrity ;,f the original intent of the symposium, it was entitled, 'Contributions of Mathematical Models to Biological Discovery'. This symposium was organized by Daniel Solomon and myself, held during the 141st annual meeting of the AAAS in New York during January, 1975, sponsored by sections G and N (Biological and Medical Sciences) of the AAAS and the North American Regions of the Biometric Society, and supported by grant BMS 75-0280) from the National Science Foundation.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The overall purpose of this monograph is to integrate and critically evaluate the existing literature in the area of optimal joint savings population programs. The existing diverse presentations are all seen to be discussions within a unified framework. The central problem is to compare the desirability of alternative inter-temporal sequences of total savings and population sizes. Of critical importance is whether one regards persons as the fundamental moral entities or whether one takes Sidgwick's viewpoint that something good being the result of one's action is the baSic reason for dOing anything. The latter viewpoint is consistent with defining a complete social preference ordering over these alternative sequences. Since part of one's interest is to evaluate the consequences of various ethical beliefs a com parative study of several such orderings is presented; in particular the Mill-Wolfe average utilitarian, and Sidgwick-Meade classical utilitarian) formulations. A possible problem with the social preference ordering approach is that the ordering may indicate the desirability of increasing the population size, if this increases the total amount of good, even though people may receive less than the welfare subsistence level of consumption. However, there are other ways of evaluating actions and, if persons are the fundamental moral entities, then perhaps these actions should be evaluated by their implications for the rights of individuals i. e. people Who are currently alive, people who one can predict will exist in the future (e. g. 136 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - Print on Demand Titel. Neuware -n this book I have tried to bring together ideas from three different Istreams of thought with which I have been closely concerned during the last thirty years or so. The first is faunal history, usually regarded as a purely academic subject, but to some of whose events can be traced a number of the serious dislocations taking place in the world today. The second is ecology, particularly the structure and dynamics of populations. The third is conservation. I first published a few ideas about the signifi cance of invasions in 1943, in a war-time review called Polish Science and Learning, under the title of 'The changing realms of animal life'. Since then I have had the opportunity to think pretty hard about conservation, while taking part in the planning and development of the Nature Con servancy. In March 1957 I gave three broadcasts in the B. B. C. 's Third Programme, under the title of 'Balance and Barrier'. These were sub sequently printed in The Listener (1957, Vol. 57, pp. 514-15,556-7,596-7, and 600). The present book is essentially an expansion of these. I am extremely grateful to Mr James C. Thornton and Dr John Simons for in planning and giving these talks. advice and help In preparing this book I have had invaluable assistance from the staff of the Bureau of Animal Population. Miss C.

However, catalyst and reaction conditions are often chosen on the analogy of literature data without a good knowledge of the influence of reaction variables and of the structure of the reactant on the various possible modes of reaction. In order to improve such an intuitive procedure it is essential to dispose of an understanding of the reaction mechanisms which are operative in hydrogena tion and hydrogenolysis reactions and which govern i.a. the selectivity of a given pathway with respect to consecutive and parallel reactions. Although organic chemistry and, in particular, hydrogenation and hydro genolysis reactions remain an experimental science this book has been written to give the organic chemist the insight and know-how necessary to apply these reactions successfully to synthetic problems. I warmly recommend it as a book which will enable the organic chemist to rationalize many of the phenomena of catalytic hydrogenation and hydrogenolysis reactions, whereby it surely helps the organic chemist to solve forthcoming synthetic problems in this field. In addition, it seems to me a useful book for physical and physical-organic chemists working in the field of homogeneous and heterogeneous catalysis. Finally, the ten years' experience of both authors in the field of catalysis and synthetic organic chemistry - as reflected by some forty publications guarantees a well-considered review containing many examples directly from the bench.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 176 pp. Englisch.

The Neurobiology meetings started about 20 years ago with the aim of bringing together scientists working on the nervous system with different methods such as anatomy, physiology, endocrinology and biochemistry, and to create a common approach to what is now called 'neurosciences'. When these meetings were in augurated by a few it was decided not to found a society, but to keep them informal and to leave it to the respective host to decide on the program and formate. At the end of each meeting, a small informal committee chose the next host and organizer. In such a way, meetings were held in various places (Amsterdam, Kiel, Stockholm, Oslo, Oxford) and on different subjects such as neuroendocrinology, the limbic and the visual systems, on excitatory and in hibitory synaptic mechanisms. The contributions to some of the meetings were published. Also, this time it was discussed whether - in view of the growth, the in creasingly structured organization and, at the same time, diversification of the neurosciences - another meeting of this sort should be held. It became during this discussion, that the tradition of these meetings should be con tinued, since they can be considered complementary to the formal, all embra cing congresses, as an informal gathering of neuroscientists interested in the borader aspects of one particular subject of this still growing discipline. 604 pp. Englisch.
