Buch. Condizione: Neu. Neuware - With the advent of CT we entered a new area of radiological imaging. Structures which rarely if ever were seen became apparent. In no part of the body was the impact of CT as profound as it was in the retroperitoneum. In the pre-CT area this region of the body could not be directly studied and only when gross abnormalities were present could they be appreciated. The best we could do was to try to identify a suspected process by studying its effect on surrounding organs whose position might have been affected by the growth. Urography, barium studies or angiography were employed in the hope that variation in the position of the vessels, ureter or bowel would lead us to the correct diagnosis. With computed tomography all this changed. Modern scanners, available to all today, permit us to appreciate details undreamed of only few years ago. The abundance of fat in this region helps to clearly show even the smallest of structures. We now have the ability to recognize small vessels, lymph nodes and fascial planes. We had a tool which permitted us to study structures which hitherto were only seen by the anatomist or during surgical dissection.

Buch. Condizione: Neu. Neuware - Only recently has the phenomenon of technology become an object of in terest for philosophers. The first attempts at a philosophy of technology date back scarcely a hundred years - a span of time extremely short when com pared with the antiquity of philosophical reflections on nature, science, and society. Over that hundred-year span, speculative, critical, and empiricist approaches of various sorts have been put forward. Nevertheless, even now there remains a broad gap between the importance of technology in the real world and the sparse number of philosophical works dedicated to the under standing of modern technology. As a result of the complex structure of modern technology, it can be dealt with in very different ways. These range from metaphysical exposition to efforts aimed at political consensus. Quite naturally, within such a broad range, certain national accents can be discovered-; they are shaped by a com mon language, accepted philosophical traditions, and concrete problems requiring consideration. Even so, the worldwide impact of technology, its penetration into all spheres of individual, social, and cultural life, together with the urgency of the problems raised in this context - all these demand a joint philosophical discussion that transcends the barriers of language and cultural differences. The papers printed here are intended to exemplify such an effort at culture-transcending philosophical discussion.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Since the last International Astronomical Union Symposium that dealt with matters cosmological, there have been dramatic advances, both on the observational and theoretical fronts. Modern high-efficiency detectors have made possible extensive magnitude-limited redshift surveys, which have permitted observational cosmologists to construct three-dimensional maps of large regions of space. What seems to emerge is a distribution of matter in extensive, flat, but probably filamentary, and possibly interconnected, superclusters, serving as interstices between vast voids in space. Meanwhile, theoretical ideas that were highly speculative a few years ago have begun to be taken seriously as possibly describing conditions in the very early universe. And brand new ideas, such as that of the inflationary universe, hold promise of solving outstanding observational, theoretical, and philosophical problems in cosmology. A new look at grand unified theories and concepts of supersymmetry have brought observational and theoretical cosmologists to a common meeting ground with modern particle physicists. 564 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The topic of sediment diagenesis is of fundamental importance to industry in the evaluation of hydrocarbon and water reservoir rocks. Detailed knowledge of the diagenetic textures, fabrics, and minerals, and a prediction of the regional diagenetic response, partly controls hydrocarbon recovery programmes. In other words, knowledge of the diagenesis can aid (or even control) conservation policy. Similarly, facies and diagenetic trends w.ithin basins can influence exploration policy. This volume incorporates the majority of the principal contributions given to the NATO Advanced Study Institute held in the University of Reading, U.K., from July 12th-25th, 1981, at which the major themes of carbonate and terrigenous clastic sediments were treated sequentially from deposition to deep burial. Eighty selected scientists from twelve NATO and three other countries participated in the Institute. The keynote addresses which acted as the touchstones for discussion are presented here in the expectation that they will stimulate a still wider audience. We gratefully acknowledge the award of a grant from the Scientific Affairs Division of NATO to run the Institute, and also the cooperation of the University of Reading. Mrs. D. M.

Since it was written, the subject has made some great advances, and Mumford's book giving a scheme theoretic treatment has appeared (D. Mum ford, Abelian Varieties, Tata Lecture Notes, Oxford University Press, London, 1970). However, some topics covered in my book were not covered in Mumford's; for instance, the construction of the Picard variety, the Albanese variety, some formulas concern ing numerical questions, the reciprocity law for correspondences and its application to Kummer theory, Chow's theory for the K/k-trace and image, and others. Several people have told me they still found a number of sections of my book useful. There fore I thank Springer-Verlag for the opportunity to keep the book in print. S. LANG v FOREWORD Pour des simplifications plus subs tan tielles, Ie developpement futur de la geometrie algebrique ne saurait manquer sans do ute d' en faire apparaitre. It is with considerable pleasure that we have seen in recent years the simplifications expected by Weil realize themselves, and it has seemed timely to incorporate them into a new book. We treat exclusively abelian varieties, and do not pretend to write a treatise on algebraic groups. Hence we have summarized in a first chapter all the general results on algebraic groups that are used in the sequel. They are all foundational results. 272 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This volume contains the Proceedings of the International Conference in Population Biology held at The University of Alberta, Edmonton, Canada from June 22 to June 30, 1982. The Conference was sponsored by The University of Alberta and The Canadian Applied Mathematics Society, and overlapped with the summer meeting of CAMS. The main objectives of this Conference were: to bring mathematicians and biologists together so that they may interact for their mutual benefit; to bring those researchers interested in modelling in ecology and those interested in modelling in genetics together; to bring in keynote speakers in the delineated areas; to have sessions of contributed papers; and to present the opportunity for researchers to conduct workshops. With the exception of the last one, the objec tives were carried out. In order to lend some focus to the Conference, the following themes were adopted: models of species growth, predator-prey, competition, mutualism, food webs, dispersion, age structure, stability, evolution of ecological parameters, evolution of behaviour, life history strategies, group and social selection, and evolution of genetic systems. There were speakers (invited and/or contributed papers) in each of these areas. Talks were given on Tuesday, June 22 to Friday, June 25 and on Monday, June 28 to Wednesday, June 30. On each day there were several talks by the principal speakers as well as contributed sessions. Altogether, there were ninety one papers given, of which twelve were by the principal speakers. There were one hundred and twenty-three registered participants from twelve different countries. 464 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The student of biological science in his final years as an undergraduate and his first years as a graduate is expected to gain some familiarity with current research at the frontiers of his discipline. New research work is published in a perplexing diversity of publications and is inevitably concerned with the minutiae of the subject. The sheer number of research journals and papers also causes confusion and difficulties of assimilation. Review articles usually presuppose a background knowledge of the field and are inevitably rather restricted in scope. There is thus a need for short but authoritative introductions to those areas of modern biological research which are either not dealt with in standard introductory textbooks or are not dealt with in sufficient detail to enable the student to go on from them to read scholarly reviews with profit. This series of books is designed to satisfy this need. The authors have been asked to produce a brief outline of their subject assuming that their readers will have read and remembered much of a standard introductory textbook of biology. 100 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The reception of the original volume by students, pedagogues, and reviewers has been most gratifying. It appears to have both satisfied a need and served a useful educational purpose. Hence, some ten years later it has been deemed advisable to bring it up to date, if only in a slightly expanded form. The purpose for writing this book and its level remain the same. Many new polymers have been synthesized in the last decade that have found meaningful and novel uses. Examples of these applications are included in this new edition. Major advances have also been made in biophysics and in molecular biology, as well as in our understanding of natural processes on a molecular level. Foremost among these has been the development of recombinant DNA technology. With it has come the potential for large scale synthesis of hormones and proteins. These new developments have also been incorporated into the present volume. It is my hope that this new edition will still have a widespread appeal to students in all of the natural sciences whatever their major interest. It should also be of use and inter est to those starting industrial or academic careers who have not had an extensive background in macromolecular science. 176 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The 11th Colloquium on Metallurgical Analysis - a joint venture of the Institute of Analytical Chemistry of the Technical University in Vienna, the Austrian Society for Analytical Chemistry and Microchemistry, the German Metals Society (DGM), and the Society of German Iron and Steel Engineers (VDEh) - was attended by 120 scientists from 12 nations. The major topics covered were surface, micro and trace analysis of materials with a heavy emphasis on metals. According to the strategy of the meeting attention was focussed on an interdisciplinary approach to materials science - combining analytical chemistry, solid state physics and tech nology. Therefore progress reports on analytical techniques (like SIMS, SNMS, Positron Annihilation Spectroscopy, AES, XPS) were given as well as pre sentations on the development of materials (like for the fusion reactor). The majority of the discussion papers centered on the treatment of important technical problems in materials science and technology by a (mostly sophis ticated) combination of physical and chemical analytical techniques. The intensive exchange of ideas and results between the scientists oriented towards basic research and the industrial materials technologists was very fruitful and resulted in the establishment of several scientific cooperations. Major trends in materials analysis were also dealt with in a plenary discussion of which a short summary is contained in this volume. In order to facilitate international communication in the field of materials analysis and in view of the important questions treated in the various contri butions this proceedings volume was edited in English. 364 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In this monograph, noncooperative games are studied. Since in a noncooperative game binding agreements are not possible, the solution of such a game has to be self enforcing, i. e. a Nash equilibrium (NASH [1950,1951J). In general, however, a game may possess many equilibria and so the problem arises which one of these should be chosen as the solution. It was first pointed out explicitly in SELTEN [1965J that I not all Nash equilibria of an extensive form game are qualified to be selected as the solution, since an equilibrium may prescribe irrational behavior at unreached parts of the game tree. Moreover, also for normal form games not all Nash equilibria are eligible, since an equilibrium need not be robust with respect to slight perturba tions in the data of the game. These observations lead to the conclusion that the Nash equilibrium concept has to be refined in order to obtain sensible solutions for every game. In the monograph, various refinements of the Nash equilibrium concept are studied. Some of these have been proposed in the literature, but others are presented here for the first time. The objective is to study the relations between these refine ments;to derive characterizations and to discuss the underlying assumptions. The greater part of the monograph (the chapters 2-5) is devoted to the study of normal form games. Extensive form games are considered in chapter 6. 164 pp. Englisch.
