Taschenbuch. Condizione: Neu. Neuware -'In 1970, at the U. of Colorado, the author delivered a course of lectures on his famous generalization, then just established, relating to Roth's theorem on rational approxi- mations to algebraic numbers. The present volume is an ex- panded and up-dated version of the original mimeographed notes on the course. As an introduction to the author's own remarkable achievements relating to the Thue-Siegel-Roth theory, the text can hardly be bettered and the tract can already be regarded as a classic in its field.'(Bull.LMS) 'Schmidt's work on approximations by algebraic numbers belongs to the deepest and most satisfactory parts of number theory. These notes give the best accessible way to learn the subject. . this book is highly recommended.'

Buch. Condizione: Neu. Neuware -This publication is concerned with two major current debates in public policy in all affluent societies. One is the widespread concern with the quality of the natural environment-the quality of air, water, land, and wilderness areas-which has expressed itself in the passage and implementation in recent years of a variety of environmental laws and regulations. A second debate concerns the adequacy of energy resources to meet the requirements of a growing economy. The requirement that industries must abate environmental pollution leads to increased costs of production and, in turn, to higher prices, falling output in those industries, and reduced employment and income in the region where such industries are located. There may be, at the same time, growth in indus tries that supply pollution abatement equipment and services in those or other regions. Over time, the health and economic benefits of higher envi ronmental quality express themselves in changing patterns of consumption.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 212 pp. Englisch.

Buch. Condizione: Neu. Neuware -One of the main ideas in organizing the Summer Institute of Cargese on 'Bifurcation Phenomena in Mathematical Physics and Related Topics' was to bring together Physicists and Mathematicians working on the properties arising from the non linearity of the phenomena and of the models that are used for their description. Among these properties the existence of bifurcations is one of the most interesting, and we had a general survey of the mathematical tools used in this field. This survey was done by M. Crandall and P. Rabinowitz and the notes enclosed in these proceedings were written by E. Buzano a]ld C. Canuto. Another mathematical approach, using Morse Theory was given by J. Smoller reporting on a joint work with C. Conley. An example of a direct application was given by M. Ghil. For physicists the theory of bifurcation is closely related to critical phenomena and this was explained in a series of talks given by J.P. Eckmann, G. Baker and M. Fisher. Some related ideas can be found in the talk given by T. T. Wu , on a joint work with Barry Mc Coy on quantum field theory. The description of these phenomena leads to the use of Pade approximants (it is explained for instance in the lectures of J. Nuttall) and then to some problems in drop hot moment problems.

Buch. Condizione: Neu. Neuware -In the study of language, as in any other systematic study, there is no neutral terminology. Every technical term is an expression of the assumptions and theoretical presuppositions of its users; and in this introduction, we want to clarify some of the issues that have surrounded the assumptions behind the use of the two terms 'speech acts' and 'pragmatics'. The notion of a speech act is fairly well understood. The theory of speech acts starts with the assumption that the minimal unit of human communica tion is not a sentence or other expression, but rather the performance of certain kinds of acts, such as making statements, asking questions, giving orders, describing, explaining, apologizing, thanking, congratulating, etc. Characteristically, a speaker performs one or more of these acts by uttering a sentence or sentences; but the act itself is not to be confused with a sentence or other expression uttered in its performance. Such types of acts as those exemplified above are called,following Austin, illocutionary acts, and they are standardly contrasted in the literature with certain other types of acts such as perlocutionary acts and propositional acts. Perlocutionary acts have to do with those effects which our utterances have on hearers which go beyond the hearer's understanding of the utterance. Such acts as convincing, persuading, annoying, amusing, and frightening are all cases of perlocutionary acts.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 336 pp. Englisch.

Buch. Condizione: Neu. Neuware - Shortly after the end of World War II high-speed digital computing machines were being developed. It was clear that the mathematical aspects of com putation needed to be reexamined in order to make efficient use of high-speed digital computers for mathematical computations. Accordingly, under the leadership of Min a Rees, John Curtiss, and others, an Institute for Numerical Analysis was set up at the University of California at Los Angeles under the sponsorship of the National Bureau of Standards. A similar institute was formed at the National Bureau of Standards in Washington, D. C. In 1949 J. Barkeley Rosser became Director of the group at UCLA for a period of two years. During this period we organized a seminar on the study of solu tions of simultaneous linear equations and on the determination of eigen values. G. Forsythe, W. Karush, C. Lanczos, T. Motzkin, L. J. Paige, and others attended this seminar. We discovered, for example, that even Gaus sian elimination was not well understood from a machine point of view and that no effective machine oriented elimination algorithm had been developed. During this period Lanczos developed his three-term relationship and I had the good fortune of suggesting the method of conjugate gradients. We dis covered afterward that the basic ideas underlying the two procedures are essentially the same. The concept of conjugacy was not new to me. In a joint paper with G. D.

This item is printed on demand - it takes 3-4 days longer - Neuware -Some years ago when I. assembled a number of general articles and lectures on probability and statistics, their publication (Essays in Probability and Statistics, Methuen, London, 1962) received a some what better reception than I had been led to expect of such a miscellany. I am consequently tempted to risk publishing this second collection, the title I have given it (taken from the first lecture) seeming to me to indicate a coherence in my articles which my publishers might otherwise be inclined to query. As in the first collection, the articles are reprinted chronologically, usually without comment. One exception is the third, not previously published and differing from the original spoken version both slightly where indicated in the text and by the addition of an Appendix. I apologize for the inevitable limitations due to date, and also for any occasional repetition of the discussion (e.g. on Bayesian methods in statistical inference). In particular, readers technically interested in the classification and use of nearest-neighbour models, a topic raised in Appendix II of the fourth article, should also refer to my monograph The Statistical Analysis of Spatial Pattern (Chapman and Hall, London, 1976), where a much more up-to-date account of these models will be found, and, incidentally, a further emphasis, if one is needed, of the common statistical theory of physics and biology.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In the past, the teaching of electricity and electronics has more often than not been carried out from a theoretical and often highly academic standpoint. Fundamentals and basic concepts have often been presented with no indication of their practical appli cations, and all too frequently they have been illustrated by artificially contrived laboratory experiments bearing little relationship to the outside world. The course comes in the form of fourteen fairly open-ended constructional experiments or projects. Each experiment has associated with it a construction exercise and an explanation. The basic idea behind this dual presentation is that the student can embark on each circuit following only the briefest possible instructions and that an open-ended approach is thereby not prejudiced by an initial lengthy encounter with the theory behind the project; this being a sure way to dampen enthusiasm at the outset. As the investigation progresses, questions inevitably arise. Descriptions of the phenomena encountered in the experiments are therefore given in the explanations. Although these were originally intended to be for the teacher's guidance they have been found, in fact, to be quite suitable for use by the student. In the explanations mathematics has been eliminated wherever possible, mechanistic descriptions of phenomena being preferred in all cases. Stress is thereby placed on concepts rather than on mere algebraic relationships. It is hoped that students of weak mathematical background will, as a result, not be prevented from following the explanations and deriving some benefit from these. 160 pp. Englisch.

Neuware -This is an 'old-fashioned' book in the best sense of the term: It is written by one man, and it is scholarly, complete, thorough, and thoughtful. It is, in fact, a magnum opus wherein every aspect is not only touched, but handled to perfec tion. This is a treatise that deserves careful reading by that increasing cadre of medical specialists who understand the many ways in which mycoses threaten human health and happiness, viz, the veterinarian, pharmaceutical chemist, general practitioner, pharmacologist, and entire consortium of researchers who study the biology, epidemiology, pathogenesis, and treatment of fungus infec tions. Mycoses encompass a vast spectrum of diseases from trivial superficial skin infections (tinea versicolor), troublesome ringworm infections (the tineas of skin, hair, and nails), yeast infections (candidosis), the systemic mycosis (cryptococcosis, histoplasmosis), and even the deep-seated infections due to molds and saprophytic fungi (aspergillosis). It is precisely because of the great variety of causative organisms that the imidazoles deserve a special treatise. They provide the first class of drugs with therapeutic activity against all the important fungi which infect humans and animals. Accordingly, their medical significance is great and the possibilities endless. Morever, the imidazoles are the first effective drugs whose antimicro bial activities extend beyond the usual designation of 'broad-spectrum. ' Broad-spectrum antibiotics, for example, are either antifungal or antibacterial, not both as the imidazoles are. To be sure, there have been other chemothera peutic compounds which inhibit bacteria and fungi.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 180 pp. Englisch.

Neuware -A rich and abundant literature has developed during the last half century dealing with mechanical aspects of the eye, mainly from clinical and, experimental points of view. For the most part, workers have attempted to shed light on the complex set of conditions known by the general term glaucoma. These conditions are characterised by an increase in intraocular pressure sufficient to cause de generation of the optic disc and concomitant defects in the visual field, which, if not controlled, lead to inevitable permanent blindness. In the United States alone, an estimated 50,000 persons are blind as a result of glaucoma, which strikes about 2% of the population over 40 years of age (Vaughan and Asbury, 1974). An understanding of the underlying mechanisms of glaucoma is hindered by the fact that elevated intraocular pressure, like a runny nose, is but a symptom which may have a variety of causes. Only by turning to the initial pathology can one hope to understand this important class of medical problems.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 116 pp. Englisch.

Neuware -The study of viruses, or virology as it is now called, had its origin in 1892 when a Russian botanist, Iwanawsky, showed that sap from a tobacco plant with an infectious disease was still highly infectious after passage through a filter capable of retaining bacterial cells. From such humble beginnings the study of these 'filter-passing agents', or viruses, has developed into a separate science which rivals, if it does not excel, in importance the whole of bacteriology. The importance of viruses lies not only in the diseases they cause in every type of living organism, but also because of their intimate relationship with the living cell, in which alone they can reproduce. Their study has influenced the whole of biology by greatly increasing our knowledge of the gene, genetics, and molecular structure; there is also the possible connexion of viruses with human cancer, in view of the occurrence of many viral cancers in other animals. The book attempts to give a comprehensive but necessarily superficial survey of the subject as a whole and should help senior undergraduates and postgraduate students who wish to gain some knowledge of virology.

IMPORTANCE OF THE SUBJECT In 1900, in A Critical Exposition of the Philosophy of Leihniz, Russell made the following assertion: 'That all sound philosophy should begin with an analysis of propositions is a truth too evident, perhaps, to demand a proof'. 1 Forty years later, the interest aroused by this notion had not decreased. C. J. Ducasse wrote in the Journal of Philosophy: 'There is perhaps no question more basic for the theory of knowledge than that of the nature of 2 propositions and their relations to judgments, sentences, facts and inferences'. Today, the great number of publications on the subject is proof that it is still of interest. One of the problems raised by propositions, the problem of deter mining whether propositions, statements or sentences are the primary bearers of truth and falsity, is even in the eyes of Bar-Hillel, 'one of the major items that the future philosophy oflanguage will have to discuss'. 3 gave a correct summary of the situation when he wrote in his Ph. Devaux Russell (1967): Since Peano and Schroder who, in fact, adhered more faithfully to Boole's logic of classes, the logical and epistemological status of the proposition together with its analysis have not ceased to be the object of productive philosophical controversies. And especially so since the establishment of contemporary symbolic logic, the foundations 4 of which have been laid out by Russell and Whitehead. \* 2.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 228 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Cloud physics has achieved such a voluminous literature over the past few decades that a significant quantitative study of the entire field would prove unwieldy. This book concentrates on one major aspect: cloud microphysics, which involves the processes that lead to the formation of individual cloud and precipitation particles. Common practice has shown that one may distinguish among the following additional major aspects: cloud dynamics, which is concerned with the physics responsible for the macroscopic features of clouds; cloud electricity, which deals with the electrical structure of clouds and the electrification processes of cloud and precipitation particles; and cloud optics and radar meteorology, which describe the effects of electromagnetic waves interacting with clouds and precipitation. Another field intimately related to cloud physics is atmospheric chemistry, which involves the chemical composition of the atmosphere and the life cycle and characteristics of its gaseous and particulate constituents. In view of the natural interdependence of the various aspects of cloud physics, the subject of microphysics cannot be discussed very meaningfully out of context. Therefore, we have found it necessary to touch briefly upon a few simple and basic concepts of cloud dynamics and thermodynamics, and to provide an account of the major characteristics of atmospheric aerosol particles. We have also included a separate chapter on some of the effects of electric fields and charges on the precipitation-forming processes. 736 pp. Englisch.
