Buch. Zustand: Neu. Neuware - In the 15 years of the acquired immunodeficiency syndrome (AIDS) pandemic much has been learnt about its natural history and complications. It is clear that the lung is a major target organ both for the human immunodeficiency virus (HIV), and a wide array of infectious and non-infectious pulmonary complications. A great deal of information on the epidemiology, microbiology, immunology, clinical features, diagnosis and management of these pulmonary complications has accumulated during the past 15 years. Given the enormous explosion in information, it is now timely to bring together this knowledge in this 25-chapter volume on AIDS and respiratory medicine. The contributors to this volume are prominent epidemiologists, doctors, microbiologists and scientists from Europe, USA and Africa. Professors Chretien and Enarson give a masterful account of the epidemiology of lung complications of HIV. Drs Zumla, Rowland Jones and Professor McMichael give a detailed summary of the lung immune responses to HIV. They outline normal lung defenses and discuss the consequences of HIV infection on them. The pulmonary radiological features of HIV and its complications as seen in the USA and Europe are illustrated by Professors Armstrong and Dee and this is compared and contrasted by Professor Tshibwabwa-Tumba who brings together his vast experience of chest X-rays in AIDS patients from Central Africa. Drs O'Doherty and Miller deal with the uses, and potential applications, of nuclear medicine in imaging of the chest in AIDS patients.…

Buch. Zustand: Neu. Neuware - In writing this book, our goal was to produce a text suitable for a first course in mathematical logic more attuned than the traditional textbooks to the re cent dramatic growth in the applications oflogic to computer science. Thus, our choice oftopics has been heavily influenced by such applications. Of course, we cover the basic traditional topics: syntax, semantics, soundnes5, completeness and compactness as well as a few more advanced results such as the theorems of Skolem-Lowenheim and Herbrand. Much ofour book, however, deals with other less traditional topics. Resolution theorem proving plays a major role in our treatment of logic especially in its application to Logic Programming and PRO LOG. We deal extensively with the mathematical foundations ofall three ofthese subjects. In addition, we include two chapters on nonclassical logics - modal and intuitionistic - that are becoming increasingly important in computer sci ence. We develop the basic material on the syntax and semantics (via Kripke frames) for each of these logics. In both cases, our approach to formal proofs, soundness and completeness uses modifications of the same tableau method in troduced for classical logic. We indicate how it can easily be adapted to various other special types of modal logics. A number of more advanced topics (includ ing nonmonotonic logic) are also briefly introduced both in the nonclassical logic chapters and in the material on Logic Programming and PROLOG.…

Buch. Zustand: Neu. Neuware - Media are objects with content and character that we describe using in- phrases: in the story, in the picture, in the movie, in the dream. Like the propositional attitudes, these objects present a variety of hard problems for semantic and philosophical analysis. The Semantics of Media is an organized exploration of fundamental questions in the semantics of media. The first three chapters set out a straightforward model within the possible-worlds framework, and consider how it might account for a range of notions applying to media generally: implicit vs. explicit content, propositional vs. individual content, causal vs. intentional content and the idea of a single World of the Medium. The final three chapters examine ways of elaborating the model to cover a range of phenomena keyed to the functionality of particular forms of media. Chapter Four is a discussion of fiction and our apparent reference to fictional characters. Chapter Five deals with the phenomenon of viewpoint in pictorial media. Chapter Six is a study of interactions between users and characters of media centering on the puzzling case of seeing in films. The Semantics of Media will be of interest to specialists in the fields of linguistics, philosophy and communications.…

Buch. Zustand: Neu. Neuware - Nitrates remain among the most commonly used therapeutic agents in cardiology. That they can re lieve pain in angina pectoris has been known at least since 1867, when Lauder Brunton described their clinical use. Now, almost 130 years later, we are constantly learning more about their optimal use in anginal syndromes. For example, there is no doubt that nitrate tolerance occurs, but equally no doubt that certain drug dosages help to attenuate such toler ance. Thus, our understanding of nitrate tolerance has been taken further by the advent of new nitrate preparations and by studies at a basic science level. The current intense interest in nitrates has been rekindled by the growing emphasis on the role of the endothelium in the production of nitric oxide, a basic cardiovascular regulator. If nitric oxide is vasodilator and protects the vascular endothelium, then nitrates should also have similar properties. Hence this book starts off with the role of the endothelium and ni trates in vasodilation. Next, the mechanisms of ac tion of nitrates are considered with emphasis on the role of cyclic GMP. The chief limitation to the use of nitrates lies in nitrate tolerance. After carefully looking at all the evidence, the authors of the third chapter conclude that the mechanism is likely to be multifactorial. The mechanism responsible for the tolerance still remains unknown. In vitro tolerance may be due to enhanced production of vascular superoxide [1].…

Buch. Zustand: Neu. Neuware - Numerical software is central to our computerized society. It is used to control aeroplanes and bridges, operate manufacturing lines, control power plants and refineries, and analyse financial markets. Such software must be accurate, reliable, robust, efficient, easy to use, maintainable and adaptable. Quality assessment and control of numerical software is still not well understood. Although measurement is a key element, it remains difficult to assess many components of software quality and to evaluate the trade-offs between them. Fortunately, as numerical software is built upon a long established foundation of mathematical and computational knowledge, there is great potential for dramatic breakthroughs. This volume will address enabling techniques and tools such as benchmarks, testing methodologies, quality standards, metrics, and accuracy control mechanisms, and their application to software for differential equations, linear algebra, data analysis, as well as the evaluation of integrals, derivatives and elementary and special functions.…

Buch. Zustand: Neu. Neuware - This state-of-the-art text explores developments in geometric modeling, product modeling and their applications. In particular, it looks at the means by which product geometry emerges from the conceptual stages of design, and the use of geometric reasoning for applications downstream of design, including manufacture ands assembly. Much existing design research is either totally geometry based or totally non-geometric, and the interface between the two areas is of intense interest to industry, as well as being crucial for the successful development of integrated systems for design and manufacture. This interface is currently not well understood and the book makes a significant contribution towards its understanding. This book is essential reading for technical managers and research and development engineers.…

Buch. Zustand: Neu. Neuware - Finite Fields are fundamental structures of Discrete Mathematics. They serve as basic data structures in pure disciplines like Finite Geometries and Combinatorics, and also have aroused much interest in applied disciplines like Coding Theory and Cryptography. A look at the topics of the proceed ings volume of the Third International Conference on Finite Fields and Their Applications (Glasgow, 1995) (see [18]), or at the list of references in I. E. Shparlinski's book [47] (a recent extensive survey on the Theory of Finite Fields with particular emphasis on computational aspects), shows that the area of Finite Fields goes through a tremendous development. The central topic of the present text is the famous Normal Basis Theo rem, a classical result from field theory, stating that in every finite dimen sional Galois extension E over F there exists an element w whose conjugates under the Galois group of E over F form an F-basis of E (i. e. , a normal basis of E over F; w is called free in E over F). For finite fields, the Nor mal Basis Theorem has first been proved by K. Hensel [19] in 1888. Since normal bases in finite fields in the last two decades have been proved to be very useful for doing arithmetic computations, at present, the algorithmic and explicit construction of (particular) such bases has become one of the major research topics in Finite Field Theory.…

Buch. Zustand: Neu. Neuware - From the President of the Research Society on Alcoholism On behalf of the Research Society on Alcoholism, I am pleased to introduce this thirteenth volume of Recent Developments in Alcoholism about alcohol and violence. Current concepts are presented in well-organized sections that - cus on epidemiology, neurobiology, psychology, and family issues. It is - coming increasingly clear that age, gender, socioeconomic circumstances, and genetics affect aggressive behavior and vulnerability to alcoholism. This v- ume contains up-to-date discussions of these issues. Indeed, the information presented here will help all alcohol researchers to identify biological and social factors that contribute to the comorbidity of alcoholism and aggression. The editors and associate editors should be congratulated for bringing toge- er such important information. This volume will be a valuable resource for investigators and therapists alike. Ivan Diamond M. D. , Ph. D. President, Research Society on Alcoholism From the President of the American Society of Addiction Medicine The American Society of Addiction Medicine is honored to continue its - sponsorship with the Research Society on Alcoholism of Recent Developmen ts in Alcoholism. The topic of alcohol and violence is a particularly timely one, given the growing number of studies that are examining the relationship between the two. These studies are consistent with the hypothesis that al- hol can increase aggression and contribute to both domestic and criminal violence. Intoxicating blood levels of alcohol have been found to be especially prevalent in those injured in fights and assaults.…

Buch. Zustand: Neu. Neuware - During the past few years, we have been witnessing the rapid growth of the ap plications of Interactive Digital Video, Multimedia Computing, Desktop Video Teleconferencing, Virtual Reality, and High Definition Television (HDTV). An other information revolution which is tied to Cyberspace is almost within reach. The information, data, text, graphics, video, sound, etc. , in the form of multi media, can be requested, accessed, distributed, and transmitted to potentially every household. This is changing and will continue to change the way of people doing business, functioning in the society, and entertaining. In the foreseeable future, many personalized, portable information terminals, which can be car ried while traveling, will provide the link to central computer network to allow information exchange including videos from a node to node, from a center to a node, or nodes. Facing this opportunity, the question is what are the major significant technical challenges that people have to solve to push the-state-of-the-art for the realiza tion of the above mentioned technology advancement From our professional judgement We feel that one of the major technical challenges is in Video Data Compression. Video communications in the form of desktop teleconferencing, videophone, network video delivery on demand, even games, are going to be major media traveling in the information super highway, hopping from one node in the Cyberspace to the other.…

Buch. Zustand: Neu.

Buch. Zustand: Neu. Neuware - Electronics has become the largest industry, surpassing agriCUlture, auto. and heavy metal industries. It has become the industry of choice for a country to prosper, already having given rise to the phenomenal prosperity of Japan. Korea. Singapore. Hong Kong. and Ireland among others. At the current growth rate, total worldwide semiconductor sales will reach $300B by the year 2000. The key electronic technologies responsible for the growth of the industry include semiconductors. the packaging of semiconductors for systems use in auto, telecom, computer, consumer, aerospace, and medical industries. displays. magnetic, and optical storage as well as software and system technologies. There has been a paradigm shift, however, in these technologies. from mainframe and supercomputer applications at any cost. to consumer applications at approximately one-tenth the cost and size. Personal computers are a good example. going from $500IMIP when products were first introduced in 1981, to a projected $lIMIP within 10 years. Thin. light portable. user friendly and very low-cost are. therefore. the attributes of tomorrow's computing and communications systems. Electronic packaging is defined as interconnection. powering, cool ing, and protecting semiconductor chips for reliable systems. It is a key enabling technology achieving the requirements for reducing the size and cost at the system and product level.…
