Buch. Condizione: Neu. Neuware - In the 1980's a primary focus for intense cardiovascular research is in the treatment of patients with acute myocardial infarction. Although the prevalence of this syndrome has been decreasing in the United States, still over 1.5 million patients develop myocardial infarction per year. There is about a 20% chance of a North American male developing myocardial in farction before the age of 65. The in-hospital mortality still remains at ap proximately 10070-15070 and advances in pharmacologic and device therapy have allowed for the intensification of research in the treatment of patients with acute myocardial infarction. The following manuscripts represent the collective efforts of academic in vestigators in the United States and abroad as well as members of the phar maceutical industry, and the Food and Drug Administration to address the issues involved in interventions in the acute phase of myocardial infarction. State-of-the-art papers addressing important topics are followed by discus sion sections which have allowed participants to express their own viewpoints leading to a consensus opinion. The first part of this Symposium addresses the models of experimental myocardial infarction followed by the important issue of how one defines myocardial infarction size. The latter is extremely important to be certain that endpoints of therapeutic or device interventions are objective and reproducible. A detailed description of the pharmacological interventions to reduce myocardial infarction size as well as newer devices to effect mechanical and electrical disorders provide an up-to-date summary of current opinion.

Neuware - On May 13-15, 1982, some 50 scientists and scholars - physicians, philos ophers and social scientists - convened at Hasselby Castle in Stockholm for the first Nordic Symposium on the Philosophy of Medicine. The topics for the symposium included (1) the concepts of health and disease, (2) classification in medicine, and (3) causality and causal explanations in medicine. The majority of the participants were Scandinavian but the symposium was also able to welcome four distinguished guests from other parts of the world, Professors Stuart F. Spicker and H. Tristram Engelhardt, Jr., U.S.A., Dr Anne M. Fagot, France, and Dr Werner Morbach, West Germany. The latter represented Professor Kazem Sadegh-zadeh, who unfortunately was prevented from attending. One of the main purposes of this symposium was to bring together people in Scandinavia who at present work within the field of Philosophy of Medi cine. This group is still relatively small but is growing rapidly, and the scholarly activity has recently been notable. This fact is clearly demonstrated by the presentation of 'Philosophy of Medicine in Scandinavia' in the Appendix of this volume.

Neuware - Curious about the images of the city that have been evolving in the different social sciences, we did what academics often do in such a situa 1 tion: we set up a seminar on 'Images of the City in the Social Sciences.' From the start, we counted on the help of specialists in other fields to pursue their interests. Of the persons who agreed to participate, all but two came from the United States, and their analyses, in the main, reflect the experience of Western countries and the United States. In our formal instructions to our collaborators, we took fir granted that a variety of images of the city could be found or inferred in their fields of expertise. We asked them to identify these images and their functions, to explain how and why they have changed over time, and to relate these images to the distinct intellectual traditions and techniques-analytical or otherwise-in their respective fields. The definition of image was left to the judgment of the participants.

Buch. Condizione: Neu. Neuware - Where do you begin to look for a recent, authoritative article on the diagnosis or management of a particular malignancy The few general oncology textbooks are generally out of date. Single papers in specialized journals are informative but seldom comprehensive; these are more often preliminary reports on a very limited number of patients. Certain general journals frequently publish good indepth reviews of cancer topics, and published symposium lectures are often the best overviews available. Unfortunately, these reviews and supplements appear sporadically, and the reader can never be sure when a topic of special interest will be covered. Cancer Treatment and Research is a series of authoritative volumes which aim to meet this need . It is an attempt to establish a critical mass of oncology literature covering virtually all oncology topics, revised frequently to keep the coverage up to date, easily available on a single library shelf or by a single personal sub scription. We have approached the problem in the following fashion. First, by dividing the oncology literature into specific subdivisions such as lung cancer, genitourin ary cancer , pediatric oncology, etc. Second, by asking eminent authorities in each of these areas to edit a volume on the specific topic on an annual or biannual basis. Each topic and tumor type is covered in a volume appearing frequently and predictably, discussing current diagnosis, staging, markers, all forms of treatment modalities, basis biology, and more .

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -At the time of writing, the topic of lead pollution is the subject of an intense and sometimes heated debate. The argument centres upon possible adverse health effects arising from exposure of children to current environmental levels of lead. Such arguments now appear little closer to resolution than they did five years ago, although the development of ever more sophisticated biochemical and epidemiological techniques may eventually provide an answer. Over the past five to ten years, as the general public has become aware of the lead issue, pressure has been put upon governments to limit emissions of lead, and hence limit or reduce the exposure of the population to the metal. Govern ments and governmental agencies have responded in several ways, varying between those who prefer to take little or no action on the basis that they see no cause for concern, and those who have taken firm action after concluding that the scientific and medical evidence warrants this approach. Any effective control strategy for lead requires knowledge of the sources of environmental exposure and an understanding of the pathways of this metal in the environment. This book aims to provide such information and to explain the methods available for limiting emissions of lead from the most important sources. To put this information in context a chapter on the routes of human exposure to lead and the health effects is included. 180 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Electromagnetism is basic to our understanding of the properties of matter and yet is often regarded as a difficult part of an under graduate physics course. In this book answers are developed from first principles to such questions as: What is electricity What is electromagnetism Why are some materials magnetic and others non-magnetic What is magnetism Physics answers these questions in two related ways. On the one hand the classical explanation is in terms of classical concepts: electric charge q, electric and magnetic fields (E and B) and electric currents. On the other hand the microscopic (or 'atomic ') explanation is in terms of quantum concepts: electrons, nuclei, electron orbits in atoms, electron spin and photons. Microscopic explanations underlie classical ones, but do not deny them. The great triumphs of classical physics are mechanics, gravitation, thermodynamics, electromagnetism and relativity. Historically they began at the time of Newton (seventeenth century) and were completed by Maxwell (nineteenth century) and Einstein (early twentieth century). Microscopic explanations began with J J. Thomson's discovery of the electron in 1897. For most physical phenomena it is best to seek a classical explanation first, especially phenomena at room temperature, or low energy, when quantum effects are small. Although this text is primarily concerned with classical explanations in a logical, self-consistent sequence, they are related to microscopic (quantum) explanations at each stage. 148 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book is a revised and up-dated fourth edition of a textbook designed for upper division courses in linear algebra. It includes the basic results on vector spaces over fields, determinants, the theory of a single linear transformation, and inner product spaces. While it does not presuppose an earlier course, many connections between linear algebra and calculus are worked into the discussion, making it best suited for students who have completed the calculus sequence. A special feature of the book is the inclusion of sections devoted to applications of linear algebra, which can either be part of a course, or used for independent study. The topics covered in these sections are the geometric interpretation of systems of linear equations, the classification of finite symmetry groups in two and three dimensions, the exponential of a matrix and its application to solving systems of first order linear differential equations with constant coefficients, and Hurwitz's theorem on the composition of quadratic forms. This revised fourth edition contains a new section on analytic methods in matrix theory, with applications to Markov chains in probability theory. Proofs of all the main theorems are included, and are presented on an equal footing with methods for solving numerical problems. Worked examples are included in almost every section, to bring out the meaning of the theorems, and to illustrate techniques for solving problems. Many numerical exercises are included, which use all the ideas, and develop computational skills. There are also exercises of a theoretical nature, which provide opportunities for students to discover interesting things for themselves. 364 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book has grown out of a set of lecture notes I had prepared for a course on Lie groups in 1966. When I lectured again on the subject in 1972, I revised the notes substantially. It is the revised version that is now appearing in book form. The theory of Lie groups plays a fundamental role in many areas of mathematics. There are a number of books on the subject currently available -most notably those of Chevalley, Jacobson, and Bourbaki-which present various aspects of the theory in great depth. However, 1 feei there is a need for a single book in English which develops both the algebraic and analytic aspects of the theory and which goes into the representation theory of semi simple Lie groups and Lie algebras in detail. This book is an attempt to fiii this need. It is my hope that this book will introduce the aspiring graduate student as well as the nonspecialist mathematician to the fundamental themes of the subject. I have made no attempt to discuss infinite-dimensional representations. This is a very active field, and a proper treatment of it would require another volume (if not more) of this size. However, the reader who wants to take up this theory will find that this book prepares him reasonably well for that task. 452 pp. Englisch.

It was one of the earliest of the quantitative sciences, and had immediate practical applications. These ranged from the study of the motion of projectiles in warfare to the motion of the planets, predicting the seasons, eclipses, etc. At the present time, even though superseded on the very small scale by quantum theory and on the very large scale by the theory of relativity, the mechanics of Newton is perfectly adequate for treating a wide spectrum of problems from the ''etic theory of gases to the motion of space vehicles. Furthermore, the science of mechanics is regarded by many as the epitome of a good scientific theory and for this reason is studied by philosophers and social scientists alike as an exemplar of the 'scientific method'. We shall commence in Chapter 1 with a brief historical outline of the development of mechanics, mentioning the names and dates of the main participants and summarizing their contributions. Preface vii Chapter 1 Newton's laws 1. 1 Historical introduction Primitive ideas about mechanics were exemplified by the state ments of Aristotle (384-322 Be), who asserted that a force was necessary to maintain motion. Furthermore, he believed that there were different laws for heavenly and earthly bodies. 128 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The main idea of this book is to present a good portion of the standard material on functions of a complex variable, as well as some new material, from the point of view of functional analysis. The main object of study is the algebra H(G) of all holomorphic functions on the open set G, with the topology on H(G) of uniform convergence on compact subsets of G. From this point of vie~, the main theorem of the theory is Theorem 9.5, which concretely identifies the dual of H(G) with the space of germs of holomorphic functions on the complement of G. From this result, for example, Runge's approximation theorem and the global Cauchy integral theorem follow in a few short steps. Other consequences of this duality theorem are the Germay interpolation theorem and the Mittag-Leffler Theorem. The approach via duality is entirely consistent with Cauchy's approach to complex variables, since curvilinear integrals are typical examples of linear functionals. The prerequisite for the book is a one-semester course in com plex variables at the undergraduate-graduate level, so that the elements of the local theory are supposed known. In particular, the Cauchy Theorem for the square and the circle are assumed, but not the global Cauchy Theorem in any of its forms. The second author has three times taught a graduate course based on this material at the University of Illinois, with good results. 188 pp. Englisch.

More recently, there has been a marked increase in the number of students in schools and colleges of further education taking 'A' level, '0' level and 'Ala' level psychology examinations. Psychology, too, features much more prominently in professional training schemes, and it is now quite common to encounter the subject in courses for police officers, clergy, teachers, nurses and other paramedical and caring profes sions. In the past, students had to rely extensively on a diet of psychology texts published in the USA, supplemented by a few modest British contributions, and by a number of specialist books written by scholars reflecting their particular interests. Nowadays, it is possible to point to a significantly larger number of British texts and monographs which deal with major issues in psychology, and a number of general textbooks have been written especially for school and college students preparing for GeE examinations. 736 pp. Englisch.

In recent years there have been several books which discusses the methodology commonly used in primary production studies and described the magnitude of photosynthetic CO reduction 2 in various areas of the world's oceans. I therefore decided to dis pense with these conventional aspects of primary production and invite researchers to speak on a variety of problems relating the abundance and activity of phytoplankton to environmental conditions. The lectures I invited were thus quite diverse in character, but all were related either to factors affecting the rate of photosynthesis or to the fate of reduced carbon as it passes through the microbial food web. In addition to these talks the participants benefited from a number of shorter presentations and poster sessions which dealt with production and cycling of organic carbon in the marine environment.

Govern ments and governmental agencies have responded in several ways, varying between those who prefer to take little or no action on the basis that they see no cause for concern, and those who have taken firm action after concluding that the scientific and medical evidence warrants this approach. Any effective control strategy for lead requires knowledge of the sources of environmental exposure and an understanding of the pathways of this metal in the environment. This book aims to provide such information and to explain the methods available for limiting emissions of lead from the most important sources. To put this information in context a chapter on the routes of human exposure to lead and the health effects is included.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 180 pp. Englisch.
