Taschenbuch. Zustand: Neu. Neuware - In this monograph, investigations of the electronic structures of the transition-metal oxides MnO, CoO, and NiO with spin-polarized electron energy-loss spectroscopy are presented and compared with other experimental and theoretical results. After a review of the present knowledge of the electronic structure of the monoxides, the spectroscopic method applied and its special advantages are described. The knowledge and use of the different spin, angle, and primary-energy dependences of the various relevant inelastic electron-scattering mechanisms provide new insights into the excitation processes of the optically forbidden transitions between the crystal-field-split 3d states of the bulk and of the surface.

Taschenbuch. Zustand: Neu. Neuware - Few human illnesses today are so challenging, medically, scientifically, and socio-economically, as the 'nonspecific' inflammatory bowel diseases (IBD): ulcerative colitis and Crohn's disease. Originating several centuries ago but essentially diseases of the 20th century, often attacking children and young adults, involving all bodily systems as well as the gastrointestinal tract, ulcerative colitis and Crohn's disease have emerged in recent decades as among the more 'glamorous' unsolved diseases, presenting unusual opportunities for insightful clinical and investigative study. Many of the prevailing concepts originated during the early and mid 20th century. The purpose of Origins and Directions of Inflammatory Bowel Disease is to review these earlier studies and their evolution 'from the mystical to the molecular,' and guide investigators and physicians through the challenging clinical and scientific maze of IBD.

Taschenbuch. Zustand: Neu. Neuware - In recent years, there has been an increased interest in the use of polarization effects for radar and electromagnetic imaging problems (References 1, 2, and 3). The problem of electro magnetic imaging can be divided into the following areas: (1) Propagation of the Stokes' vector from the transmitter to the target region through various atmospheric conditions (rain, dust, fog, clouds, turbulence, etc.). (2) Scattering of the Stokes' vector from the object. (3) Scattering of the Stokes' vector from the rough surface, terrain, and the volume scattering. (4) Propagation of the Stokes' vector from the target region to the receiver. (5) The characteristics of the receiver relating the Stokes' vector to the output. The propagation characteristics of the Stokes' vector through various media can be described by the equation of transfer. Even though the scalar equation of transfer has been studied extensively in the past, the vector equation of transfer has not received as much attention. In recent years, however, a need for further study of the vector radiative transfer theory has become increasingly evident and several important studies have been reported. This paper presents a general formulation of the vector theory of radiative transfer under general anisotropic scattering conditions. Some useful solutions are also presented 4 8 for several practical situations. - 2.

Taschenbuch. Zustand: Neu. Neuware -Logic Programming is the name given to a distinctive style of programming, very different from that of conventional programming languages such as C++ and Java. By far the most widely used Logic Programming language is Prolog. Prolog is a good choice for developing complex applications, especially in the field of Artificial Intelligence.Logic Programming with Prolog does not assume that the reader is an experienced programmer or has a background in Mathematics, Logic or Artificial Intelligence. It starts from scratch and aims to arrive at the point where quite powerful programs can be written in the language. It is intended both as a textbook for an introductory course and as a self-study book. On completion readers will know enough to use Prolog in their own research or practical projects.Each chapter has self-assessment exercises so that readers may check their own progress. A glossary of the technical terms used completes the book.This second edition has been revised to be fully compatible with SWI-Prolog, a popular multi-platform public domain implementation of the language. Additional chapters have been added covering the use of Prolog to analyse English sentences and to illustrate how Prolog can be used to implement applications of an 'Artificial Intelligence' kind.Max Bramer is Emeritus Professor of Information Technology at the University of Portsmouth, England. He has taught Prolog to undergraduate computer science students and used Prolog in his own work for many years. 268 pp. Englisch.

Buch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Viscous flow is treated usually in the frame of boundary-layer theory and as two-dimensional flow. Books on boundary layers give at most the describing equations for three-dimensional boundary layers, and solutions often only for some special cases.This book provides basic principles and theoretical foundations regarding three-dimensional attached viscous flow. Emphasis is put on general three-dimensional attached viscous flows and not on three-dimensional boundary layers. This wider scope is necessary in view of the theoretical and practical problems to be mastered in practice. The topics are weak, strong, and global interaction, the locality principle, properties of three-dimensional viscous flow, thermal surface effects, characteristic properties, wall compatibility conditions, connections between inviscid and viscous flow, flow topology, quasi-one- and two-dimensional flows, laminar-turbulent transition and turbulence. Though the primary flight speed range is that of civil air transport vehicles, flows past other flying vehicles up to hypersonic speeds are also considered. Emphasis is put on general three-dimensional attached viscous flows and not on three-dimensional boundary layers, as this wider scope is necessary in view of the theoretical and practical problems that have to be overcome in practice.The specific topics covered include weak, strong, and global interaction; the locality principle; properties of three-dimensional viscous flows; thermal surface effects; characteristic properties; wall compatibility conditions; connections between inviscid and viscous flows; flow topology; quasi-one- and two-dimensional flows; laminar-turbulent transition; and turbulence. Detailed discussions of examples illustrate these topics and the relevant phenomena encountered in three-dimensional viscous flows. The full governing equations, reference-temperature relations for qualitative considerations and estimations of flow properties, and coordinates for fuselages and wings are also provided. Sample problems with solutions allow readers to test their understanding.

Taschenbuch. Zustand: Neu. Neuware - Neuropsychology has become an increasingly active participant in forensie issues over the past decade. This has been the result of increased recognition by psychologists of the potential role they can play in evaluating patients involved in lawsuits and the increasing sophistication of lawyers who have recognized that damages can go beyond claims of physical and motoric impairment. However, this increase in involvement has not always been matched by a more sophisticated recognition of how the client (whether plaintiff or defendant) can best be served by the neuropsychologist. I have personally seen or reviewed many cases in which the psychologists involved did not effectively present their case. This partially occurred because they failed to recognize the difference in presentations aimed at clinical audiences and those aimed at a legal proceeding. It also occurred because they failed to recognize that the standard of proof necessary is very different in a hospital and in a courtroom. Finally, it occurred because they rarely recognized what the unique role of the psychologist can be in either countering or supporting the testimony of medical specialists. The purpose of this volume is to bring some light on these questions. The presentations here are write-ups of the work presented at the Third Annual Conference on the Luria-Nebraska Neuropsychological Battery held in Omaha during May, 1985. All of the papers emphasize the role of the Luria-Nebraska but the ideas can be used with almost any test.

Taschenbuch. Zustand: Neu. Neuware - This volume developed from and around a series of six lectures sponsored by Rice University and the University of Texas Medical Branch at Galveston in the Fall of 1976. Though these lectures on the concepts of mental health, mental illness and personal responsibility, and the social treatment of the mentally ill were given to general audiences in Houston and Galveston, they were revised and expanded to produce six extensive formal essays by Dan Brock, Jules Coleman, Joseph Margolis, Michael Moore, Jerome Neu, and Rolf Sartorius. The five remaining contributions by Daniel Creson, Corinna Delkeskamp, Edmund Erde, James Speer, and Stephen Wear were in various ways engendered by the debates occasioned by the original six lectures. In fact, the majority of the last five contributions emerged from informal dis cussions occasioned by the original lecture series. The result is an interlocking set of essays that address the law and public policy insofar as they bear on the treatment of the mentally ill, special atten tion being given to the defmition of mental illness, generally and in the law, to the issues of the bearing of mental incompetence in cases of criminal and civil liability, and to the issue of involuntary commitment for the purpose of treatment or for institutional care. There is as well a critical defense of Thomas Szasz's radical proposal that mental illnesses are best understood as problems in living, not as diseases.

Taschenbuch. Zustand: Neu. Neuware - This is a book by people who have had to make decisions which affect the environment in which we all live, decisions which sometimes affect the quality of life of millions. It is not an academic disquisition on how to approach decision-making. Most of the chapters are written by scientists who have had to take action or make recommendations on environmental matters in situations where the data are incomplete or choices hedged by factors beyond scientific resolution; the result is that they have had to resolve dilemmas about the proper way forward in the matter. My brief to the authors was to describe issues with which they had been personally concerned, rather than simply select from the vast range of envir- mental problems 'out there'. The only exception to this was Andrew Brennan (Chapter 1), who is a professional philosopher; I asked him to say something about the processes and errors indulged by environmental decision-makers. There is some overlap between chapters, but this is not extensive. I have made no attempt to eliminate it, because the aim has been to present personal points of view, not a systematic account of environmental problems. Similarly, there are important topics which are not covered. Indeed, a critic would complain that a book on environmental dilemmas which does not deal directly with the crucial divide between development and conservation is almost wholly irrelevant; from one point of view, it could be condemned as fiddling while Rome burns.

Taschenbuch. Zustand: Neu. Neuware - This volume contains the review papers presented at the International Symposium on Solar-Terrestrial Physics held at the Tavrichesky Palace, Leningrad, U.S.S.R., 11-19 May 1970. The Symposium may be regarded as the most recent member of a series of inter national symposia - for instance, the Symposium on Solar-Terrestrial Physics, Belgrade (1966), the Joint IQSY-COSPAR Symposium on Solar-Terrestrial Physics, London (1967), and the Symposium on the Physics of the Magnetosphere, Washington (1968). Like those earlier symposia, the Leningrad Symposium was sponsored by the International Astronomical Union (IAU), the International Union of Geodesy and Geophysics (IUGG), the International Union of Radio Sciences (URSI), and the ICSU Committee on Space Research (COSPAR). These bodies are all concerned with one or another aspect of solar-terrestrial physics, and all joined in believing that the time was ripe for another comprehensive symposium on all aspects of this very active field of research.

Taschenbuch. Zustand: Neu. Neuware - The observation of the scaling properties of the structure functions w and vw of deep inelastic electron 1 2 nucleon scattering [1]+ has been taken by many people as an indication for an approximate scale invariance of the world. It was pointed out by Wilson [2], that in many field theories it is possible to assign a dimension d to every fundamental field, which proves to be a conserved quantum number as far as the most singular term of an operator product expansion at small distances ((x-y) +a) is con- JJ cerned++. Later it was shown, at the canonical level, that in many field theories the dimension of a field seems to be a c:pod quantum number even in the terms less singular at small (x-y) , as long as they all belong to the strongest l light cone singularity (i. e. (x-y)2+a) [3]. The assumption that this type of scale invariance on the light cone be present in the operator product ex pansion of two electromagnetic currents has provided us with a rather natural explanation of the observed scaling phenomena. We should like to mention, however, that this ex planation cannot account for the precocity with which scaling is being observed experimentally in energy regions, in which resonances still provide prominent contributions to the final states [4].

Neuware - How influential has the Nazi analogy been in recent medical debates on euthanasia Is the history of eugenics being revived in modern genetic technologies And what does the tragic history of thalidomide and its recent reintroduction for new medical treatments tell us about how governments solve ethical dilemmas Bioethics in Historical Perspective shows how our understanding of medical history still plays a part in clinical medicine and medical research today. With clear and balanced explanations of complex issues, this extensively documented set of case studies in biomedical ethics explores the important role played by history in thinking about modern medical practice and policy.This book provides student readers with up-to-date information about issues in bioethics, as well as a guide to the most influential ethical standpoints. New twists added to well-known stories will engage those more familiar with the challenging field of contemporary bioethics.

Taschenbuch. Zustand: Neu. Neuware - The Royal Institute of Philosophy has been sponsoring conferences in alternate years since 1969. These have from the start been intended to be of interest to persons who are not philosophers by profession. They have mainly focused on interdisciplinary areas such as the philosophies of psychology, education and the social sciences. The volumes arising from these conferences have included discussions between philosophers and distinguished practitioners of other disciplines relevant to the chosen topic. Beginning with the 1979 conference on 'Law, Morality and Rights' and the 1981 conference on 'Space, Time and Causality' these volumes are now constituted as a series. It is h.

Taschenbuch. Zustand: Neu. Neuware - The division of the mature mammalian brain and spinal cord into regions of 'white' matter and 'gray' matter is observable upon the most cursory inspection. Microscopic examination indicates that the 'white' matter regions are characterized by a multilamellar sheath (myelin) which sur rounds the axons. A morphologically similar myelin imparts the white color to tracts of the peripheral nervous system, although, as is empha sized throughout the book, there are very significant morphological and chemical differences between central and peripheral myelin. The rapid postnatal accumulation of myelin is temporally associated with increasing functional capacity and presumably indicates some important role related to neuronal activity. The ability of myelinated axons to conduct electrical impulses much more rapidly and with much lower use of energy, relative to unmyelinated axons, is now generally accepted. As is evident from the above capsule description, a considerable body of information concerning myelin is available. However, as in other areas of research the unknown expands before us more rapidly than we are able to add to our core of knowledge. This is a corollary of the axiom that a good experiment raises more questions than it answers. Among the areas currendy under investigation in many laboratories are the following: interaction of myelin-forming cells with neurons, assembly and metabo lism of myelin, molecular architecture of myelin, and the details of the functional role of myelin.

Taschenbuch. Zustand: Neu. Neuware - Substance misuse and abuse exist in almost every human society. In our western civilization, the bulk of attention has focused on those indi viduals who specifically seek treatment or those who have become so disabled by these problems that they require treatment. These indi viduals usually qualify for a psychiatric diagnosis of alcohol or other substance abuse. However, just as it has been recognized that primary substance abuse is frequently associated with other diagnosable psychi atric disorders, such as sociopathy or attention deficit disorder (residual type) and that the origins of substance abuse are multivariate, we have also begun to become aware that many other individuals in our society with psychiatric or other problems also suffer, to varying degrees, from substance abuse. These problems may be considered secondary by vari ous specialists or treatment personnel; but nevertheless, they are prob lems, and what disorder is primary or secondary in a given individual may often be very difficult to determine in a meaningful fashion. Thus, within the past decade, research studies have reported significant inci dences of substance abuse/or misuse in high school and college-aged populations, in medical populations, and in individuals with other psy chiatric disorders such as schizophrenia, depression, and the anxiety and personality disorders. Yet to date little has been done to bring together and systematize this widely scattered data that describes the presence of substance abuse problems in various populations.

Taschenbuch. Zustand: Neu. Neuware - Nonsmooth energy functions govern phenomena which occur frequently in nature and in all areas of life. They constitute a fascinating subject in mathematics and permit the rational understanding of yet unsolved or partially solved questions in mechanics, engineering and economics. This is the first book to provide a complete and rigorous presentation of the quasidifferentiability approach to nonconvex, possibly nonsmooth, energy functions, of the derivation and study of the corresponding variational expressions in mechanics, engineering and economics, and of their numerical treatment. The new variational formulations derived are illustrated by many interesting numerical problems. The techniques presented will permit the reader to check any solution obtained by other heuristic techniques for nonconvex, nonsmooth energy problems. A civil, mechanical or aeronautical engineer can find in the book the only existing mathematically sound technique for the formulation and study of nonconvex, nonsmooth energy problems. Audience: The book will be of interest to pure and applied mathematicians, physicists, researchers in mechanics, civil, mechanical and aeronautical engineers, structural analysts and software developers. It is also suitable for graduate courses in nonlinear mechanics, nonsmooth analysis, applied optimization, control, calculus of variations and computational mechanics.

Taschenbuch. Zustand: Neu. Neuware - Phenomenology as practised by Adolf Reinach ( 1883-191 7) in his all too brief philosophical career exemplifies all the virtues of Husserl's Logical Investigations. It is sober, concerned to be clear and deals with specific problems. It is therefore understandable that, in a philosophical climate in which Husserl's masterpiece has come to be regarded as a mere stepping stone on the way to his later Phenomeno logy, or even to the writings of a Heidegger, Reinach's contributions to exact philo sophy have been all but totally forgotten. The topics on which Reinach wrote most illuminatingly, speech acts (which he called 'social acts') and states of affairs (Sachverhalte ), as well as his realism about the external world, have come to be regarded as the preserve of other traditions of exact philosophy. Like my fellow contributors, I hope that the present volume will go some way towards correcting this unfortunate historical accident. Reinach's account of judgements and states of affairs, an account that precedes those of Russell and Wittgenstein, his 1913 treatment of speech acts, his reinter pretation of Hume and aspects of his legal philosophy are the main philosophical topics dealt with in what follows. But his analysis of deliberation as well as his work on movement and Zeno's paradoxes get only a passing mention.

Taschenbuch. Zustand: Neu. Neuware - Science is not a mere collection of facts. It is the correlation of facts, the interpretative synthesis of the available knowledge and its application that excite the imagination of a scientist. Even in these days of modern technology, the need for quick and accurate dissemination of new information and current concepts still exists. Conferences and Symposia offer one direct method of communication. The Summer Schools are another approach. The success of a Summer School is mainly due to that human factor and under standing that goes with it and allows for extensive and often time-unrestricted discussions. During the course of the past 20 years, one of the most in tensively studied groups of elements in the Periodic Table is the Lanthanides. In this period, we have increased our knowledge on these once exotic elements, which were once considered to be a part of a lean and hungry industry, many-fold due to the involve ment of scientists from various disciplines. The purpose of our Summer School was to bring a group of ex perts and participants together for the exchange of ideas and in formation in an informal setting and to promote interdisciplinary interactions. Out of many conceivable topics, we selected the following five as the main basis to broaden our knowledge and understanding I) Systematics 2) Structure 3) Electronic and Magnetic Proper ties 4) Spectroscopic Properties and 5) Lanthanide Geochemistry.

Buch. Zustand: Neu. Neuware - This is the first major textbook to address both computed tomography (CT) and magnetic resonance (MR) cardiac imaging of adults for the diagnosis and treatment of congenital heart disease (CHD). Since the introduction of faster CT scanners, there has been tremendous advancement in the diagnosis of CHD in adults. This is mostly due to the higher spatial resolution of CT compared to MR, which enables radiologists to create more detailed visualizations of cardiac anatomic structures, leading to the discovery of anomalous pathologies often missed by conventional MR imaging. This book is unique in highlighting the advantages of both CT and MR for the diagnosis of CHD in adults, focusing on the complementary collaboration between the two modalities that is possible. Chapters include discussions of case examples, clinical data, MR and CT image findings, and correlative cadaveric pictures. The chapters focus not only on the diagnosis of the primary problem, but also give readers informationon visual clues to look for that often reveal associated pathologies. This book appeals primarily to diagnostic and interventional radiologists, as well as cardiologists and interventional cardiologists.

Taschenbuch. Zustand: Neu. Neuware - Photonic band gap crystals offer unique ways to tailor light and the propagation of electromagnetic waves. In analogy to electrons in a crystal, EM waves propagating in a structure with a periodically-modulated dielectric constant are organized into photonic bands separated by gaps in which propagating states are forbidden. Proposed applications of such photonic band gap crystals, operating at frequencies from microwave to optical, include zero- threshold lasers, low-loss resonators and cavities, and efficient microwave antennas. Spontaneous emission is suppressed for photons in the photonic band gap, offering novel approaches to manipulating the EM field and creating high-efficiency light-emitting structures. Photonic Band Gap Materials identifies three most promising areas of research. The first is materials fabrication, involving the creation of high quality, low loss, periodic dielectric structures. The smallest photonic crystals yet fabricated have been made by machining Si wafers along (110), and some have lattice constants as small as 500 microns. The second area is in applications. Possible applications presented are microwave mirrors, directional antennas, resonators (especially in the 2 GHz region), filters, waveguides, Y splitters, and resonant microcavities. The third area covers fundamentally new physical phenomena in condensed matter physics and quantum optics. An excellent review of recent development, covering theoretical, experimental and applied aspects. Interesting and stimulating reading for active researchers, as well as a useful reference for non-specialists.

Taschenbuch. Zustand: Neu. Neuware - I Modern times has invented its own brand of Apocalypse. Famine is no longer one of the familiar outriders. The problems of material life, and their political and psychological implications, have changed drastically in the course of the past two hundred years. Perhaps nothing has more profoundly affected our institutions and our attitudes than the creation of a technology of abundance. - Even the old tropes have given way: neither dollars nor calories can measure the distance which separates gagne-pain from gagne-hi/leek. 1 Yet the concerns of this book seem much less remote today than they did when it was conceived in the late sixties. In the past few years we have begun to worry, with a sort of expiatory zeal, about the state of our environment, the size of our population, the political economy and the morality of the allocation of goods and jobs, and the future of our resources. While computer projections cast a malthusian pall over our world, we have had a bitter, first-hand tasteof shortages of all kinds. The sempiternal battle between producers and consumers rages with a new ferocity, as high prices provoke anger on the one side and celebration on the other. Even as famines continue to strike the third world in the thermidor of the green revolution, so we have discovered hunger in our own midst.
