Buch. Condizione: Neu. Neuware -From the reviews: 'A good introduction to a subject important for its capacity to circumvent theoretical and practical obstacles, and therefore particularly prized in the applications of mathematics. The book presents a balanced view of the methods and their usefulness: integrals on the real line and in the complex plane which arise in different contexts, and solutions of differential equations not expressible as integrals. Murray includes both historical remarks and references to sources or other more complete treatments. More useful as a guide for self-study than as a reference work, it is accessible to any upperclass mathematics undergraduate. Some exercises and a short bibliography included. Even with E.T. Copson's Asymptotic Expansions or N.G. de Bruijn's Asymptotic Methods in Analysis (1958), any academic library would do well to have this excellent introduction.' (S.

Taschenbuch. Condizione: Neu. Neuware -Stratified fluids whose densities, sound speeds and other parameters are functions of a single depth coordinate occur widely in nature. Indeed, the earth's gravitational field imposes a stratification on its atmosphere, oceans and lakes. It is well known that their stratification has a profound effect on the propagation of sound in these fluids. The most striking effect is probably the occurrence of acoustic ducts, due to minima of the sound speed, that can trap sound waves and cause them to propagate hori zontally. The reflection, transmission and distortion of sonar signals by acoustic ducts is important in interpreting sonar echoes. Signal scattering by layers of microscopic marine organisms is important to both sonar engi neers and marine biologists. Again, reflection of signals from bottom sediment layers overlying a penetrable bottom are of interest both as sources of unwanted echoes and in the acoustic probing of such layers. Many other examples could be given. The purpose of this monograph is to develop from first principles a theory of sound propagation in stratified fluids whose densities and sound speeds are essentially arbitrary functions of the depth. In physical terms, the propagation of both time-harmonic and transient fields is analyzed. The corresponding mathematical model leads to the study of boundary value problems for a scalar wave equation whose coefficients contain the pre scribed density and sound speed functions.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 212 pp. Englisch.

Buch. Condizione: Neu. Neuware - In this book, I discuss the question whether God exists, not as a Tillichian religious symbol, but as an actual person, albeit a person who is very different from you and me. My procedure is to examine arguments bdth for and against God's existence qua person and to assess their relative merits. I shall try to show that there is more evidence that God exists than that he does not. This position is, of course, rejected nowadays, even by most religious thinkers, who hold, for one reason or another, that evidence has nothing to do with religious belief, properly understood. My reply to these thinkers is simply to ask them to examine what follows. A useful companion to Chapters 4, 5, 6, 7, and the Appendix of this book would be Alvin Plantinga's The Nature of Necessity.l Though I avoid technical terminology wherever possible, those chapters presuppose an elementary understanding of 'possible worlds' discourse; and a clear and concise explanation of that terminology can be found in Chapter IV of Plantinga's book. Also, I use 'logical' throughout to mean what Plantinga means by 'broadly logical' on page 2 of The Nature of Necessity.

Buch. Condizione: Neu. Neuware -The discovery of the earth's radiation belts in 1957 marked the beginning of what is now known as magnetospheric physics. The field has evolved normally from an early discovery phase through a period of exploration and into an era of quantitative studies of the dynamics of magnetized plasmas as they occur in nature. Such environments are common throughout the universe and have been studied in varying detail at the sun, the planets, pulsars, and certain radio galaxies. The purpose of this book is to describe basic quantitative aspects of magnetospheric physics. We use selected examples from the earth's magnetosphere to show how theory and data together form a quantitative framework for magnetospheric research. We have tried to organize the material along the philosophy of starting simply and adding com plexity only as necessary. We have avoided controversial and relatively new research topics and have tried to use as examples physical processes generally accepted as important within the earth's magnetospheric system. However, even in some of our examples, the question of whether the physical process applied to a particular problem is the dominant process, has yet to be answered.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 252 pp. Englisch.

Buch. Condizione: Neu. Neuware - One of the ironies of our time is the sparsity of useful analytic tools for understanding change and development within technology itself. For all the diatribes about the disastrous effects of technology on modern life, for all the equally uncritical paeans to technology as the panacea for human ills, the vociferous pro- and anti-technology movements have failed to illuminate the nature of technology. On a more scholarly level, in the midst of claims by Marxists and non-Marxists alike about the technological underpinnings of the major social and economic changes of the last couple of centuries, and despite advice given to government and industry about managing science and technology by a small army of consultants and policy analysts, technology itself remains locked inside an impenetrable black box, a deus ex machina to be invoked when all other explanations of puzzling social and economic pheoomena fail. The discipline that has probably done most to penetrate that black box in recent years by studying the 1 internal development of technology is history. Historians of technology and certain economic historians have carried out careful and detailed studies on the genesis and impact of technological innovations, and the structu-re of the social systems associated with those innovations. Within the past few decades tentative consensus about the periodization and the major traditions within the history of technology has begun to emerge, at least as far as Britain and America in the eighteenth and nineteenth century are concerned.

Buch. Condizione: Neu. Neuware -Monte Carlo methods have been a tool of theoretical and computational scientists for many years. In particular, the invention and percolation of the algorithm of Metropolis, Rosenbluth, Rosenbluth, Teller, and Teller sparked a rapid growth of applications to classical statistical mechanics. Although proposals for treatment of quantum systems had been made even earlier, only a few serious calculations had heen carried out. Ruch calculations are generally more consuming of computer resources than for classical systems and no universal algorithm had--or indeed has yet-- emerged. However, with advances in techniques and in sheer computing power, Monte Carlo methods have been used with considerable success in treating quantum fluids and crystals, simple models of nuclear matter, and few-body nuclei. Research at several institutions suggest that they may offer a new approach to quantum chemistry, one that is independent of basis ann yet capable of chemical accuracy. That. Monte Carlo methods can attain the very great precision needed is itself a remarkable achievement. More recently, new interest in such methods has arisen in two new a~as. Particle theorists, in particular K. Wilson, have drawn attention to the rich analogy between quantum field theoty and statistical mechanics and to the merits of Monte Carlo calculations for lattice gauge theories. This has become a rapidly growing sub-field. A related development is associated with lattice problems in quantum physics, particularly with models of solid state systems. The~ is much ferment in the calculation of various one-dimensional problems such as the'Hubbard model.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 304 pp. Englisch.

Buch. Condizione: Neu. Neuware - This is a book about dreaming and knowing, and about thinking that one can ascertain the difference. It is a book about the Bernards of the world who would have us believe that there is a humanly uncreated world existing en Boi that freely dis closes its forever fixed ontology, even though they too must accept that -many of the worlds we make as we try to under stand ourselves are counterfeit. It is a book about the real estate of the human mind. The book is about Leibniz and Kant, and about methods of science. It is also about what is now called pseudo-science. It tries to show how Kant struggled to mark the limits of the humanly knowable, and how thi s strug gle involved him in trying to answer questions of importance then and now. Some are philosophers' questions: the epistemo logical status of mathematics, the role of space and time in knowing, the nature of the conceptual constraints on our ef forts to hypothesize the possible. Some are questions of per ennial human interest: Can spirits exist How is the soul re lated to the body How can we legitimately talk about God, if at all Finally, Kant teaches that these are all questions bearing on our entitlements in claiming to know. Leibniz fashioned a way of talking about nature and super nature that I call the Double Government Methodology.

Buch. Condizione: Neu. Neuware - J. DE GROOTE One of the most ominous and troublesome complications of the liver disease is the appearance of hemorrhagic phenomena. Many careful clini cal observations about the relationship of liver function and of bilia ry tree pathology have been published. A vast amount of research work has been devoted to the subject. The severity of the hemorrhagic disor der is usually in relation to the liver disease. In mild chronic hepa titis or short lasting obstruction slight subcutaneous or mucosal blee ding may (lraw the attention of the patient and the doctor, but they are as such far from dangerous. However in acute hepatic insufficiency, in biliary cirrhosis the bleeding tendency is to be considered as a life threatening complication in about half of the cases. Moreover coagulation disturbances aggravate bleeding not only from ruptured oesophageal or gastric varices but also from gastritis or peptic ulcer. 11enometrorrhagia, epistaxis and gingival bleeding may be very trouble some in these conditions. The use of diagnostic procedures sucl. as liver puncture biopsy and peritoneoscopy are often impossible when platelets and prothrombine time are too low. In order to overcome this difficul ty a procedure has been worked out taking a biopsy through a trans jugular catheter placed in the hepatic vein. If a bleeding from the liver occurs it will be in the circulatory system and not cause any trouble.

Buch. Condizione: Neu. Neuware - Research on antiviral drugs and their mode of action in infected cells. in animals and in man. has led to a better understanding of the molecular pro cesses involved in virus replication. Screeninq of large numbers of natural and semisynthetic compounds resulted in the characterization of certain sub stances that had a limited efficiency as antiviral druqs. A few chemically synthesized compounds were also found to be effective as antiviral agents in the chemotherapy of human virus diseases. A major difficulty in the develop ment of effective antiviral agents has been the lack of selectivity. and toxicity for uninfected cells. of drugs that effectively inhibited virus replication in vitro. Further understanding of the molecular processes of virus replication in infected cells has resulted in the development of new antivirals directed at virus-coded enzymes or proteins. Recent studies on antivirals that are activated by the herpes simplex virus type l-coded thy midine kinase from a prod rug to an antiviral drug have opened new directions in the development of effective antiviral drugs. The present book deals with a number of antiviral drugs effective against herpes simplex viruses and provides some insight into the molecular aspects of virus replication. It also throws light on the new approaches to the development of antiviral drugs. The molecular basis of the antiviral activity of new and known drugs and their possible use in chemotherapy of viral disease are presented in this book.

Buch. Condizione: Neu. Neuware - An International Conference on the Application of Fracture Mechanics to Ma terials and Structures was held at the Hotel Kolpinghaus in Freiburg, West Ger many, June 20-24, 1983. It was attended by more than 250 participants from different countries which include Austria, Canada, Czechoslovakia, Democratic Republic of Germany, Denmark, Federal Republic of Germany, Finland, France, Greece, Hungary, Israel, Italy, Japan, Netherlands, Norway, People's Republic of China, Portugal, Sweden, Switzerland, United Kingdom, United States of America, USSR and Yugoslavia. Conference Co-Chairmen were Professor G. C. Sih, Lehigh University, Bethle hem, Pennsylvania, U. S. A. , Dr. E. Sommer, Fraunhofer-Institut fur Werkstoff mechanik, Freiburg, FRG and Professor W. Dahl, Rheinisch-Westfalische Technische Hochschule, Aachen, FRG. Dr. Wenrich, as the representative of the Land Baden-WUrttemberg, delivered the opening address with the remarks that International Conferences can serve the means to further enhance the technology development of a country. He empha sized that the Federal Republic of Germany is presently in need of strengthening the engineering manpower in order to keep her in a competitive position. The Conference was officially cast off with the leading plenary lectures that under lined the theme of the technical lectures for the first day. This pattern was observed for the five-day meeting. The interplay between material and design re quirements was the theme and emphasized in many of the technical presentations that amounted to approximately ninety (90) papers.

Viele Griinde bewirkten, daB dieses Gebiet erst in neuester Zeit wissenschaftlich fundiert wird. Neben der Kompliziertheit der Vorgange und der Schwierigkeit des Experimentierens bei Tempera turen um 1500 °0 sind hierfiir die umfangreichen Erfahrungen verant wortlich, welche die Menschheit seit den ersten Anfangen der Zivilisation iiber die Eigenschaften und die Verwendung des Feuers gesammelt hat, so daB gute empirische Losungen fiir viele technische Aufgaben zur Ver fiigung stehen. Hinzu kommt, daB Dampfkessel, IndustrieOfen und hausliche Feuerstatten unabhangig voneinander entwickelt wurden, ganz zu schweigen von Raketen, Gasturbinen und Kolbenmotoren. Indessen miissen alle diese Fachrichtungen auf den gleichen Grund lagen aufbauen, alle Flammen beruhen auf einem Zusammenwirken von Reaktionen mit Austauschvorgangen von Stoff, Warme und Impuls. Ohne Einsicht in den Ausbreitungsvorgang einer Flammenfront kann man den Stabilisierungsmechanismus einer Diffusionsflamme nicht ver stehen. In diesem Buch habe ich versucht, die gemeinsamen Grundlagen aller Verbrennungsvorgange zu beschreiben und ihre Anwendung auf Feue rungen, d. h. Warmetauscher mit Verbrennung, in einer Form zu zeigen, die den Bediirfnissen des Ingenieurs entspricht. Verbrennungsanlagen, die der direkten Erzeugung mechanischer Energie dienen, werden nur soweit erwahnt, als die hier gegebenen Grundlagen dies zwanglos zulassen.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 452 pp. Deutsch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Local interstitial radiation therapy of intrinsic and inaccessible brain tumors is confronted with two major problems: 1. The tolerance of normal brain tissue, which is usually involved in local tumor irradiation, i.e. perifocal white matter edema and demyelinating effects, is crucial. 2. Data on radiation effects of implanted radioactive sources on neoplastic tissue, i.e. data on the radiosensitivity and on the biology of tumors, are still widely unavailable. In clinical practice the dose with which to achieve a given volume of tumor necrosis is roughly estimated. This report deals with the experimental findings of Iodine-125 and Iridium-I92 permanent implants in healthy and neoplastic brain tissue. Our own experimental findings are correlated with experimental data on Yttnul11-l)O irradiation from the literature. The study is directed to collect data on the tolerance non-tumoral brain tissue and to attempt to establish a dose-response relationship. Morphologic Changes in the Dog Brain Following Interstitial Iodine-125 Irradiation Iodine-I25 seeds (manufactured by 3 M Company, St. Paul, M. N.) with an activity of 3.55 mCi were permanently implanted under stereotactic conditions into the subcortical white matter of the gyrus coronalis of the left hemisphere in 6 beagle dogs. One animal with a non-radioactive seed implanted under similar operative conditions served as a control. The animals were allowed to survive 25, 46, 71, 94, 248, 368 days, respectively, after the implantation. The control animal survived 46 days. A detailed description of the experimental procedure is given elsewhere 16. 17. 604 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -About ten years aga devices and equipment were developed for producing quantitative images in vivo of the distribution of substanees with positron emitting radionuclide label of very short half-life (down to only several minutes). The positron-emitting isotopes can be the most important bio elements and are, therefore, suitable for the labeling of important physio logie substrates like sugars, amino acids ete. and their synthetic analogues. Their imaging, after distribution in vivo, is being performed by PET scan ning systems. It soon became apparent that positron-emission tomography could be very useful in the field of cancer biology, diagnostics and therapy. Trans port, influx and efflux, metabolism of suitable labeled substrates around and in tumors can be followed over aperiod oftime, thus allowing the - calization oftumors and - equally important - the efficiency (or non-effi ciency) of any given therapeutic regimen. For this purpose 13N-Iabeled amino acids, especially glutamate, or l1C_ and 18P-labeled glucose deri vates were introduced and are already being recommended for the study of special tumors in experimental animals and man, such as brain tumors or osteosarcomas. Some glucose derivatives were developed which differ in their metabolie (enzymatic) fate. In this way, combined application of compounds, like [18F]-2-fluoro-2-deoxy- and rtC]-3-0-methyl-D-glucose are 'expected to provide the most important imaging in tumor diagno stics' (M. Hatanaka).

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -To the Second Edition This book is designed both for introductory courses in computer problem solving, at the freshman and sophomore college level, and for individual self study. The first edition of this book has been used for teaching introductory classes at University of California San Diego (UCSD), University of California Irvine (UCI), and many other schools. This second edition is based on our experience using the text over the past six years with a broad range of students. We have taught the course using variations on Keller's Personalized System of Instruction (PSI). The organization of this book is conducive to this approach but does not require it. PSI methods allow slightly more material to be absorbed by the students than is the case with the traditional lecture/recitation presentation. PSI allows grading according to the number of chapter units completed. In a 10 week quarter, virtually all students who pass the course at UCSDand UCI complete the material covered in the first eleven chapters and the exercises associated with them. A substantial portion complete the entire fifteen chapters. For a conventional presentation under the semester system, the 15 chapters should present an appropriate amount of material for the average student. 356 pp. Englisch.
