Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Earth structures engineering involves the analysis, design and construction of structures, such as slopes and dams, that are composed mainly of earth materials, and this is a growth area in geotechnical engineering practice. This growth is due largely to increased involvement in designing various types of earth structures for the resources industries (slopes, impoundment structures, offshore islands, mine backfills), to the development of increas ingly large hydroelectric projects, to the need for more freshwater storage and diversion schemes, and to the need for transportation, communications and other facilities in areas where the natural earth materials are occasionally subject to mass instabilities. Although geotechnical engineering transects traditional disciplinary boundaries of civil, geological and mining engineering, the majority of geotechnical engineers are graduates from civil engineering schools. Here the geotechnical instruction has been concentrated on soil mechanics and foundation engineering because foundation engineering has traditionally been the major component of geotechnical practice. Geotechnical special ists, however, generally have acquired considerable formal or informal training beyond their first engineering degree, and an advanced degree with considerable cross-discipline course content is still considered an advantage for a young engineer entering a career in geotechnical engineering. Practical job experience is, of course, a necessary part of professional development but is readily interpreted and assimilated only if the required background training has been obtained. 280 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Edward Gibbon's allegation at the beginning of his Essay on the Study of Literature (1764) that the history of empires is that of the miseries of humankind whereas the history of the sciences is that of their splendour and happiness has for a long time been accepted by professional scientists and by historians of science alike. For its practitioner, the history of a discipline displayed above all the always difficult but fmally rewarding approach to a truth which was incorporated in the discipline in its actual fonn. Looking back, it was only too easy to distinguish those who erred and heretics in the field from the few forerunners of true science. On the one hand, the traditional history of science was told as a story of hero and hero worship, on the other hand it was, paradoxically enough, the constant attempt to remind the scientist whom he should better forget. It is not surprising at all therefore that the traditional history of science was a field of only minor interest for the practitioner of a distinct scientific diSCipline or specialty and at the same time a hardly challenging task for the professional historian. Nietzsche had already described the historian of science as someone who arrives late after harvest-time: it is somebody who is only a tolerated guest at the thanksgiving dinner of the scientific community . 336 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A growing interest has been shown recently in the dymanics of nitrogen in agricultural and natural ecosystems. This has been caused by increasing demands for food and fibre by a rapidly expanding world population, and by a growing concern that increased land clearing, cultivation and use of both fertilizer and biologically fixed nitrogen can have detrimental effects on the environment. These include effects on water quality, eutrophication of surface waters and changes in atmospheric composition all caused by increased cycling of nitrogenous compounds. The input and availability of nitrogen frequently affects the productivity of farming systems more than any other single management factor, but often the nitrogen is used inefficiently. Much of the fertilizer nitrogen applied to the soil is not utilised by the crop: it is lost either in solution form, by leaching of nitrate, or in gaseous forms as ammonia, nitrous oxide, nitric oxide or dinitrogen. The leached nitrate can contaminate rivers and ground waters, while the emitted ammonia can contaminate surface waters or combine with atmospheric sulfur dioxide to form aerosols which affect visibility, health and climate. There is also concern that increased evolution of nitrous oxide will deplete the protective ozone layer of the stratosphere. The possibility of a link between the intensity of agricultural use of nitrogen, nitrous oxide emissions and amounts of stratospheric ozone has focussed attention on these interactions. 332 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Functional integration is one of the most powerful methods of contempo rary theoretical physics, enabling us to simplify, accelerate, and make clearer the process of the theoretician's analytical work. Interest in this method and the endeavour to master it creatively grows incessantly. This book presents a study of the application of functional integration methods to a wide range of contemporary theoretical physics problems. The concept of a functional integral is introduced as a method of quantizing finite-dimensional mechanical systems, as an alternative to ordinary quantum mechanics. The problems of systems quantization with constraints and the manifolds quantization are presented here for the first time in a monograph. The application of the functional integration methods to systems with an infinite number of degrees of freedom allows one to uniquely introduce and formulate the diagram perturbation theory in quantum field theory and statistical physics. This approach is significantly simpler than the widely accepted method using an operator approach. 312 pp. Englisch. …

Buch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -PREFACE This volume is a sequel to yet independent of our Paranoia: A Study in Diagnosis, Reidel, Dordrecht and Boston, 1976. Whereas our first book centered on diagnosis, this centers on treatment. In our first volume, all discussions of nosology (theory of illness) and of treatment was ancillary to our discussion of diagnosis; similarly all discussion of this volume dealing with nosology - there is very little on diagnosis here - is ancillary to our discussion of psychotherapy. It is still our profoundest conviction that to speak of treatment without diagnosis is meaningless, if not irresponsible, since otherwise one does not know what one is talking about. Hence, our present study, though it centers on theories of treatment, links psychotherapy with psychopathology. It is the rationale of psychotherapy which is of importance, and the rationale dwells in this link. We wish our present study to be self-contained and understood by readers who are not familiar with our first book - or with any specific literature. Our discussion of medicine in general, meaning the rationale of therapy in general, helps the uninitiated reader, as well as the initiated, we hope: it certainly has helped us. We did not see how else can we study a branch of medicine; we felt the need for some idea of how medicine is supposed to work.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 206 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -Traditionally, solar and stellar physics have been two separate branches of astronomy, which independently of each other have developed their own scientific goals and methods. During the last decade, however, we have witnessed a gradual convergence of these two areas: The solar physicists realize more and more that the sun has to be seen as a special case in a large family of stars of various properties. A more complete understanding of the sun can only be achieved by considering it in this broader context. The stellar physicists on the other hand have become aware that the detailed knowledge of the physical processes that the solar physicists have reached has a more general significance and can be applied to a variety of other astrophysical objects. Observational techniques developed in solar work can frequently be adapted for other stars as well. This unified approach to solar and stellar physics is often called the 'solar-stellar connection'. One main goal of this approach has been to understand the general nature and causes of stellar activity. The pioneering and visionary program to search for activity cycles on other stars started by Olin Wilson at the Mount Wilson Observatory 16 years ago has born fruit: in his sample of 91 stars, cyclic behaviour similar to that of the sun is found to be quite common, but many stars also show irregular activity fluctua.tions of large amplitude. 574 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -The book is divided into chapters, but several themes run across them. This is, in fact, the reason for writing a book rather than a number of independent articles; for it appears that several moments of Kant's work are characterized by similar problems, and consequently we might be unable to see the impact of these on a more 1 i mi ted canvas. But further, and perhaps no less importantly, the shared problems are likely to be indicative of the nature of the whole area under discussion. Given this, to concentrate our attention on them should provide clarification not accessible in any other way. It is one of the objects of the present book to obtai n thi s clarification, and to apply it to the area itself, rather than merely to utilize the results in Kantian exegesis and elucidation. Thus the aim is not predominantly historical. Of the various themes, the theme of Space and Time turns out to be of prime importance to the whole picture presented, and within it, the theme of space. This is not perhaps surprising, for Kant's central task is to provide for objectivity; i. e. , to explain how a 'subjective' stream of perceptions can amount to a perception of the world in which there are both subjective and objective moments.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 196 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Katherine Teilmann Van Dusen and Sarnoff A. Mednick This introduction delineates what we consider to be three of the most important impediments to the advance of knowledge in the field of criminology. The most fundamental need is for more studies of the nature and progress of criminal and delinquent careers. The second need is for more prospective, longitudinal studies of the etiology of crime and delinquency. The third need concerns the lack of interdisciplinary research toward a more integrated understanding of delinquent and criminal behavior. Criminal and Delinquent Careers The birth cohort study by Wolfgang, Figlio and Sellin (1972) was heralded by many (Farrington, 1973; Erickson, 1973; Weis, 1974) as a landmark which allowed researchers to study the course of delinquency without the usual sampling biases that plagued other, cross-sectional research. For the first time, we could get a reasonable picture of when delinquency usually starts, what proportion of the population engages in delinquency, what types of delinquencies they engage in, what proportion continue, and so on. Cross sectional studies do not permit the investigation of careers because cross 1 PROSPECTIVE STUDIES OF CRIME AND DELINQUENCY 2 sectional sampling includes only portions of careers for many of the individuals sampled. This is just one of the many problems that restricted researchers' ability to study the nature of criminal careers. 428 pp. Englisch.…

At the present summer scnool we concentrated on only part of the subject area that was covered in 1980. Although there was some repetit ion of material that was presented in 1980, because by and large we had a new set of participants, most subjects were treated in considerably greater detail than had been possible previously. The major topics covered in the present summer school were (i) the general principles of remote sensing with particular reference to marine applications, (ii) applications to physical oceanography, (iii) marine resources applications and (iv) coastal monitoring and protection. The material contained in this volume represents the written texts of most of the lectures presented at the summer school. One important set of lecture notes was not available; this was for the lectures on active microwave techniques, principally synthetic aperture radar, by W. Alpers from Hamburg. For this material we would refer the reader to 'Imaging Ocean Surface Waves by Synthetic Aperture Radar - A Review' by W.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Particle astronomy - the study of cosmic radiation - was the first of the new astronomies to emerge in the twentieth cen tury. Although cosmic-ray phenomena have been fruitfully investi gated for some seventy years, the central engima - the origin of these high-energy particles - remains a challenge. Among the ob servational clues to possible sites and mechanisms of cosmic-ray production, none carries more information than the composition and energy distribution of the particles arriving in the solar system. The present volume is the work of many participants in a NATO Advanced Study Institute on 'The Composition and Origin of Cosmic Rays' held from the 20th to the 30th of June, 1982 under the aus pices of the Ettore Majorana Centre for Scientific Culture. Par ticipants came to the Centre in Erice, Sicily from eight countries. This Institute was also the third Course of the International School of Cosmic-Ray Astrophysics, which has been meeting bienni ally 1n Erice. Of the two previous Courses, likewise sponsored by the Majorana Centre, the first (1978) provided a broad introduction to th~ field. It was entitled 'Progress and Problems in Cosmic Ray Physics.' The second (1980) was devoted to 'Acceleration of Particles in Nature.' It treated mechanisms of acceleration, some candidate sites, and observational and theoretical constraints. Director of the Majorana Centre is Prof. Antonino Zichichi. 428 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume contains the proceedings of a NATO/London Mathematical Society Advanced Study Institute held in Oxford from 25 July - 7 August 1982. The institute concerned the theory and applications of systems of nonlinear partial differential equations, with emphasis on techniques appropriate to systems of more than one equation. Most of the lecturers and participants were analysts specializing in partial differential equations, but also present were a number of numerical analysts, workers in mechanics, and other applied mathematicians. The organizing committee for the institute was J.M. Ball (Heriot-Watt), T.B. Benjamin (Oxford), J. Carr (Heriot-Watt), C.M. Dafermos (Brown), S. Hildebrandt (Bonn) and J.S. pym (Sheffield) . The programme of the institute consisted of a number of courses of expository lectures, together with special sessions on different topics. It is a pleasure to thank all the lecturers for the care they took in the preparation of their talks, and S.S. Antman, A.J. Chorin, J.K. Hale and J.E. Marsden for the organization of their special sessions. The institute was made possible by financial support from NATO, the London Mathematical Society, the u.S. Army Research Office, the u.S. Army European Research Office, and the u.S. National Science Foundation. The lectures were held in the Mathematical Institute of the University of Oxford, and residential accommodation was provided at Hertford College. 496 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In the field of heterogeneous catalysis. it is convenient to distinguish. in a perfectly unjustified and over simplified way. bet:leen metal catalysts. 2nd the other catalysts. The fj.J'st are easy to define : they are those in which a reduced metal is the active phase. It is thus easy to circumscribe. by exclusion, the other class namely the 'non-metals'. We have adopted this definition for the sake of our colleagues working on catalysis by metals, and to avoid a lengthy title like 'sm' face pl'operties and catalysts by transi tion metal oxides. sulftdes, carbides, nitriles, etc. Defined in this manner, non-metal catalysts represented, in 1980, 84 wt. % of the industrial heterogeneous catalysts. To be more specific, this proportion corresponds to catalysts which, under the working conditions in the industrial lant. contain their catalytically active metallic elements in a non-reduced state. It should however be recalled that most metal catalysts are supported on oxides, which, often, repl'esent over 90% (sometimes 99.4% in the case of the platinum reforming catalysts) of the total weight. 580 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Attilio Ferrari I want to recall here the basic points I raised at the beginning of the Workshop as the main targets of discussion (in the name of the Scientific Committee). I attempted to focus the attention of participants on the fact that, in many instances, we tend to discuss jets in terms of simple physics, more or less as one did at the time extragalactic radio sources were discovered: for instance, we still use equipartition arguments. However, we must realize that processes in jets, leading to their morphologies and energetics clearly depend on complex plasma phenomena. Therefore, the same standard arguments used to derive characteristic parameters should be questioned; some of the speakers were invited to attempt a critical analysis of this point, an~ in fact I believe that this 'inquisitive attitude' was actually present all along the Workshop. Observers were asked to choose the parameters to be used in a statistical sample of jets. For this they were urged, first of all, to distinguish between primary and secondary features. For instance, are knots and wiggles common to all jets Are relativistic flow velocities expected in all active nuclei Are jets denser or lighter than the external medium On the theoretical side I asked to discuss whether or not existing models are in accordance with the limited statistical sample that we have today. And which should be the lines of development to be pursued first, and to what extent. 348 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -While ion-exchange processes were originally used for the treatment of very dilute solutions, many applications for the treatment of concentrated solu tions have been developed in recent years. In these situations, the mass transfer bottlenecks are located in the~, rather than the liquid phase. Therefore, the development of quantitative models for ion-exchange kinetics requires knowledge about the conductance characteristics of ions and solvent in the solid phase. A useful approach towards this aim is the study of trans port characteristics of these species, and of their interactions in solid ion exchange membranes. Many different transport processes and related phenomena can be observed in membrane-solution systems, e.g., ion migration, electroosmosis, diffusion arid self-diffusion, osmosis, hydraulic flow, hyperfiltration (reverse osmosis) or ultrafiltration, streaming potential and streaming current, and membrane potentials (also called 'membrane concentration potentials'). It is important to correlate all these phenomena so as to avoid a very large number of unnec essary measurements. Such correlation is often possible [Meares, 1976] since all these phenomena are determined by the ease of migration of the different species across the membrane. Important correlations have been made and summar ized even before high-capacity ion-exchange membranes became commercially available [Sollner, 1950, 197iJ. 472 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The preceding Preface, which Professor William Frankena had the great kindness to write as an introduction for the readers of the present English translation of my major work, still requires several supplementary com ments on my part. Professor Frankena rightly considered it to be an advan tage to introduce the English-speaking world to my moral philosophy through its presentation in this book. As an introduction to my moral philosophy, Professor Frankena provided a concise formulation of the fun damental ideas of my ethics by quoting from an article I had just recently published. Several points worth mentioning remain. Firstly, it is necessary to distinguish the two editions of the text here translated. The first edition was published in 1951 by Anton Hain in Meisenheim am Glan, under the title Pflicht und Neigung (Duty and In clination), with the subtitle Die Grundlagen der Sittlichkeit, erOrtert und neu bestimmt mit besonderem Bezug auf Kant und Schiller (The Fun damentals of Morality, Discussed and Redefined with Special Regard to Kant and Schiller). In 1974, a revised and enlarged second edition was published by the same publisher and was entitled Die Grundlagen der Sitt Iichkeit (The Fundamentals of Morality). Of this second edition, the first four chapters have been translated in the present volume, along with four more recent essays. 324 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Whenever one attempts to write about a philosopher whose native tongue is not English the problem of translations is inevitable. For the sake of simplicity and accuracy we have translated all of our quotations from the German unless otherwise noted. But for the sake of easy reference we have included the page numbers of the English translations as well as the German texts. Because there is a new translation forthcoming, we have not included references to the English translation of Ideen I. Since the German texts are readily available, we did not reproduce them in the footnotes. All quotations translated from Husserl's unpublished manuscripts, however, do include the German text in the footnotes. This work is greatly indebted to the criticism and help of Professor Ludwig Landgrebe, whose support made possible two years at the UniversiHit Koln. Garth Gillan and Lothar Eley also have contributed much to the basic direction ofthis work. Others such as Edward Casey, Claude Evans, Irene Grypari, Don Ihde, Grant Johnson, Martin Lang, J. N. Mohanty, Robert Ray and Susan Wood have been more than helpful in their discussions with me on these topics and in their criticisms of some of the ambiguities of an earlier draft. Likewise a special word of thanks to Reto Parpan whose insightful corrections were most valuable and to Nancy Gifford for her discussions on matters epistemolo gical and for her help in the final preparation of the book. 352 pp. Englisch.…

We have adopted this definition for the sake of our colleagues working on catalysis by metals, and to avoid a lengthy title like 'sm' face pl'operties and catalysts by transi tion metal oxides. sulftdes, carbides, nitriles, etc. Defined in this manner, non-metal catalysts represented, in 1980, 84 wt. % of the industrial heterogeneous catalysts. To be more specific, this proportion corresponds to catalysts which, under the working conditions in the industrial lant. contain their catalytically active metallic elements in a non-reduced state. It should however be recalled that most metal catalysts are supported on oxides, which, often, repl'esent over 90% (sometimes 99.4% in the case of the platinum reforming catalysts) of the total weight.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 580 pp. Englisch. …

Buch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -This volume contains the proceedings of a NATO/London Mathematical Society Advanced Study Institute held in Oxford from 25 July - 7 August 1982. The institute concerned the theory and applications of systems of nonlinear partial differential equations, with emphasis on techniques appropriate to systems of more than one equation. Most of the lecturers and participants were analysts specializing in partial differential equations, but also present were a number of numerical analysts, workers in mechanics, and other applied mathematicians. The organizing committee for the institute was J.M. Ball (Heriot-Watt), T.B. Benjamin (Oxford), J. Carr (Heriot-Watt), C.M. Dafermos (Brown), S. Hildebrandt (Bonn) and J.S. pym (Sheffield) . The programme of the institute consisted of a number of courses of expository lectures, together with special sessions on different topics. It is a pleasure to thank all the lecturers for the care they took in the preparation of their talks, and S.S. Antman, A.J. Chorin, J.K. Hale and J.E. Marsden for the organization of their special sessions. The institute was made possible by financial support from NATO, the London Mathematical Society, the u.S. Army Research Office, the u.S. Army European Research Office, and the u.S. National Science Foundation. The lectures were held in the Mathematical Institute of the University of Oxford, and residential accommodation was provided at Hertford College.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 496 pp. Englisch.…
