Taschenbuch. Etat : Neu. Neuware -Concentrations of pollutants in the atmosphere have increased dramatically over the last century and many of these changes are attributable to anthropogenic activities. The influence of acid rain has been well studied, but there has been no extensive exploration of other pollutants, such as toxic chemicals, heavy metals and radionuclides. Natural ecosystems, especially forests, tend to accumulate many of these pollutants which subsequently can affect ecosystem health. These contaminants may be very damaging to the environment in Eastern Europe, where the rapid disappearance of forest is the result not only of contamination but also of poor forest management practices.The current book is designed to reduce the uncertainty in our current knowledge of forest radioecology. The three topics it embraces are (a) Modelling, (b) Measurements and Data, and (c) Countermeasures and Risk Assessment.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 448 pp. Englisch.

Buch. Etat : Neu. Neuware -This interesting book deals with the theory of convex and starlike biholomorphic mappings in several complex variables. The underly ing theme is the extension to several complex variables of geometric aspects of the classical theory of univalent functions. Because the author's introduction provides an excellent overview of the content of the book, I will not duplicate the effort here. Rather, I will place the book into historical context. The theory of univalent functions long has been an important part of the study of holomorphic functions of one complex variable. The roots of the subject go back to the famous Riemann Mapping Theorem which asserts that a simply connected region n which is a proper subset of the complex plane C is biholomorphically equivalent to the open unit disk ~. That is, there is a univalent function (holo morphic bijection) I : ~ -+ n. In the early part of this century work began to focus on the class S of normalized (f (0) = 0 and I' (0) = 1) univalent functions defined on the unit disk. The restriction to uni valent functions defined on the unit disk is justified by the Riemann Mapping Theorem. The subject contains many beautiful results that were obtained by fundamental techniques developed by many mathe maticians, including Koebe, Bieberbach, Loewner, Goluzin, Grunsky, and Schiffer. The best-known aspect of univalent function theory is the so-called Bieberbach conjecture which was proved by de Branges in 1984.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 228 pp. Englisch.

Buch. Etat : Neu. Neuware -In this fresh translation of five lectures delivered in 1907 at the University of Göttingen, Edmund Husserl lays out the philosophical problem of knowledge, indicates the requirements for its solution, and for the first time introduces the phenomenological method of reduction. For those interested in the genesis and development of Husserl's phenomenology, this text affords a unique glimpse into the epistemological motivation of his work, his concept of intentionality, and the formation of central phenomenological concepts that will later go by the names of `transcendental consciousness', the `noema', and the like. As a teaching text, The Idea of Phenomenology is ideal: it is brief, it is unencumbered by the technical terminology of Husserl's later work, it bears a clear connection to the problem of knowledge as formulated in the Cartesian tradition, and it is accompanied by a translator's introduction that clearly spells out the structure, argument, and movement of the text.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 80 pp. Englisch.

Buch. Etat : Neu. Neuware -Climate change is one of the major environmental concern of many countries in the world. Negotiations to control potential climate changes have been taking place, from Rio to Kyoto, for the last five years. There is a widespread consciousness that the risk of incurring in relevant economic and environmental losses due to climate change is high. Scientific analyses have become more and more precise on the likely impacts of climate change. According to the Second Assessment Report of the Intergovernmental Panel on Climate Change, current trends in greenhouse gases (GHGs) emissions may indeed cause the average global temperature to increase by 1-3. 5 °C over the next 100 years. As a result, sea levels are expected to rise by 15 to 95 em and climate zones to shift towards the poles by 150 to 550 km in mid latitudes. In order to mitigate the adverse effects of climate change, the IPCC report concludes that a stabilization of atmospheric concentration of carbon dioxide - one of the major GHGs - at 550 parts per million by volume (ppmv) is recommended. This would imply a reduction of global emissions of about 50 per cent with respect to current levels. In this context, countries are negotiating to achieve a world-wide agreement on GHGs emissions control in order to stabilize climate changes. Despite the agreement on targets achieved in Kyoto, many issues still remain unresolved.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 242 pp. Englisch.

Buch. Etat : Neu. Neuware -Since the initiative works for global analysis of linear differential equations by G.G. Stokes and B. Riemann in 1857, the Airy function and the Gauss hypergeometric function became the most important and the greatest practical special functions, which have a variety of applications to mathematical science, physics and engineering. The cffcctivity of these functions is essentially due to their 'behavior in the large' . For instance, the Airy function plays a basic role in the asymptotic analysis of many functions arising as solutions of differential equations in several problems of applied math ematics. In case of the employment of its behavior, one should always pay attention to the Stokes phenomenon. On the other hand, as is well-known, the Gauss hypergeometric function arises in all fields of mathematics, e.g., in number theory, in the theory of groups and in analysis itself. It is not too much to say that all power series are special or extended cases of the hypergeometric series. For the full use of its properties, one needs connection formulas or contiguous relations.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 548 pp. Englisch.

Buch. Etat : Neu. Neuware -The Bear Brook Watershed in Maine (BBWM) is a long-term, whole-watershed study examining the effects of experimentally elevated N and S deposition on a treated watershed, in comparison to the adjacent reference watershed. The study is in a northern New England, USA, forested ecosystem, and focuses on soil and stream hydrological and biogeochemical processes, and chemical responses of vegetation. Relative to the reference watershed, the treated ecosystem has migrated biogeochemically towards N saturation, and soil and stream acidification. Some of the responses to N amendments were not expected nor predicted by available models.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 260 pp. Englisch.

Buch. Etat : Neu. Neuware -Measuring Up revisits vital issues of equity and assessment through the research efforts and insights of many of the nation's most prominent educators and assessment experts. As its most urgent purpose, the publication aims to sensitize readers to the unfairness and inappropriate uses of testing instruments which under optimal circumstances have the potential to benefit all students.With America fervently espousing both national and state testing, the differential performance by race and social class raises the specter of tests as barriers to life milestones such as promotion, graduation, and college admissions. In response to such punitive testing, the papers included here explore a host of models and practices that are currently being piloted both in America and abroad as educators grapple with the effects the assessment is having on minority and disadvantaged students and school systems. In the process, outcomes of innovative portfolio and authentic assessments are weighed against important standards and principles of validity and consequences.As the various authors probe the gap between African-American and White test scores, they raise important questions of resources, family background and educational opportunity. Beyond their value of their recommendations to educators, their papers help to identify causes of pupil deficiencies in ways that can be addressed by policymakers. To reinforce the emphasis on equity, several authors present a definitive defense of affirmative action as a critical counter-measure to the lack of fairness in school quality, family and social supports, and educational resources.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 288 pp. Englisch.

Buch. Etat : Neu. Neuware -The last decade has been one of dramatic progress in the field of Natural Language Processing (NLP). This hitherto largely academic discipline has found itself at the center of an information revolution ushered in by the Internet age, as demand for human-computer communication and informa tion access has exploded. Emerging applications in computer-assisted infor mation production and dissemination, automated understanding of news, understanding of spoken language, and processing of foreign languages have given impetus to research that resulted in a new generation of robust tools, systems, and commercial products. Well-positioned government research funding, particularly in the U. S. , has helped to advance the state-of-the art at an unprecedented pace, in no small measure thanks to the rigorous 1 evaluations. This volume focuses on the use of Natural Language Processing in In formation Retrieval (IR), an area of science and technology that deals with cataloging, categorization, classification, and search of large amounts of information, particularly in textual form. An outcome of an information retrieval process is usually a set of documents containing information on a given topic, and may consist of newspaper-like articles, memos, reports of any kind, entire books, as well as annotated image and sound files. Since we assume that the information is primarily encoded as text, IR is also a natural language processing problem: in order to decide if a document is relevant to a given information need, one needs to be able to understand its content.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 412 pp. Englisch.

Buch. Etat : Neu. Neuware -The first edition of this book (1958) described an analytical situation which had existed for a number of years for maintaining quality control on vulcanizates of natural rubber although the situation had recently been disturbed by the introduction of a range of synthetic rubbers which required identification and quantitative estimation. For the former purpose 'wet' chemistry, based on various imperfectly understood organic reactions, was pressed into service. Alongside this was the first introduction of instrumental analysis, using the infrared spectra of either the polymers or, more usually, their pyrolytic products to 'fingerprint' the material. The identification of a range of organic accelerators, antioxidants and their derivatives which had been intro duced during the 1920s and 30s was, in the first edition, dealt with by a combination of column chromatography and infrared spectroscopy or by paper chromatography. Quantitative procedures were, however, still classical in the tradition of gravimetric or volumetric assays with an initially weighed sample yielding, after chemical manipulation, a carefully precipitated, dried and weighed end product, or a solution of known composition whose weight or titre, as a percentage of the initial sample, quantified the function being determined. The second edition of this work (1968) consolidated the newer techni ques which had been introduced in the first without adding to them although, in other applications of analytical chemistry, instrumental analysis had already brought about a transformation in laboratory practice.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 400 pp. Englisch.

Buch. Etat : Neu. Neuware -Phenomenology, according to Husserl, is meant to be philosophy as rigorous science. It was Franz Brentano who inspired him to pursue the ideal of scientific philosophy. Though Husserl began his philosophical career as an orthodox disciple of Brentano, he eventually began to have doubts about this orientation. The Logische Unterschungen is the result of such doubts. Especially after the publication of that work, he became increasingly convinced that, in the interests of scientific philosophy, he had to go in a direction which diverged from Brentano and other members of this school (`Brentanists') who believed in the same ideal. An attempt is made here to ascertain Husserl's philosophical relation to Brentano and certain other Brentanists (Carl Stumpf, Benno Kerry, Kasimir Twardowski, Alexius Meinong, and Anton Marty). The crucial turning point in the development of these relations is to be found in the essay which Husserl wrote in 1894 (particularly in response to Twardowski) under the title `Intentional Objects' (which is translated as an appendix in this volume).This study will be of interest to historians of philosophy and phenomenology in particular, but also to anyone concerned with the ideal of scientific philosophy.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 380 pp. Englisch.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -DNA delivery into cells is a rapidly developing area in gene therapy and biotechnology. Moreover, it is a powerful research tool to determine gene structure, regulation, and function. Viral methods of DNA delivery are well-characterized and efficient, but little is known about the toxicity and immunogenecity of viral vectors. As a result, non-viral, transfection methods of DNA delivery are of increasing interest. Synthetic DNA Delivery Systems is a comprehensive and current resource on DNA transfection. The use of histidine-rich peptides and polypeptides as DNA delivery systems and self-assembled delivery systems based on cationic lipids and polymers are discussed. Targeted delivery to organelles, tumor cells and dendritic cells comprise an important topic. 512 pp. Englisch.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The Proceedings of the tenth Advanced Study Institute (ASI) on Tech niques and Concepts of High Energy Physics are dedicated to Jane and Bob Wilson. Jane joined Bob at St. Croix for the first session of this Institute, after Bob had stepped down as director of Fermilab, and was scheming to build a modest charm factory in the parking lot of Columbia University's Nevis Laboratory. Through the years, Bob has been a great friend of the School, and much of its success and flavor can be attributed to his guidance and support. The 1998 meeting was held once again at the Hotel on the Cay, and, as before, the work and the fun went on very enjoyably. We had a to tal of 76 participants from 23 countries, with the main financial support for the meeting provided by the Scientific Affairs Division of the North Atlantic Treaty Organization (NATO). The ASI was co-sponsored by the U. S. Department of Energy, by the Fermi National Accelerator Laboratory (Fermilab), by the U.S. National Science Foundation, and by the University of Rochester. As in the case of the previous ASIs, the scientific program was designed for advanced graduate students and recent PhD recipients in experimental particle physics. The present volume of lectures should complement and update the material published (by Plenum) for the first nine ASIs and prove to be of value to a wider audience of physicists. 644 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A major flaw in semi-Riemannian geometry is a shortage of suitable types of maps between semi-Riemannian manifolds that will compare their geometric properties. Here, a class of such maps called semi-Riemannian maps is introduced. The main purpose of this book is to present results in semi-Riemannian geometry obtained by the existence of such a map between semi-Riemannian manifolds, as well as to encourage the reader to explore these maps. The first three chapters are devoted to the development of fundamental concepts and formulas in semi-Riemannian geometry which are used throughout the work. In Chapters 4 and 5 semi-Riemannian maps and such maps with respect to a semi-Riemannian foliation are studied. Chapter 6 studies the maps from a semi-Riemannian manifold to 1-dimensional semi- Euclidean space. In Chapter 7 some splitting theorems are obtained by using the existence of a semi-Riemannian map. Audience: This volume will be of interest to mathematicians and physicists whose work involves differential geometry, global analysis, or relativity and gravitation. 212 pp. Englisch.

Neuware -The International Workshop on Coherent Control of Carrier Dynamics in Semiconductors was held May 19 to 22, 1998 at the University of Illinois at Chicago. Its intent was to bring together an international and interdisciplinary group of scientists to discuss recent progress, pertinent problems, and open questions in the field of coherent control in atoms, molecules, and semiconductors, in particular. Twenty-seven scientists from the physical chemistry, quantum optics, semiconductor, electrical engineering, and laser communities accepted our invitation and made this event a meeting of exciting presentations and vivid discussions. This volume contains the proceedings of this workshop. Most speakers accepted our invitation to provide a manuscript either on specific aspects of their work or a brief review of their area of research. All manuscripts were reviewed. It is hoped that they provide not merely an overview of most of the issues covered during the workshop, but also represent an account of the current state of coherent control in general. Hence, it is hoped that they are also of interest to a large number of scientists active in one of the areas listed above. The organizers of this workshop would like to thank all the participants for making this meeting a complete success. We are particularly indebted to Dr. Larry R. Cooper at the U.S. Office of Naval Research and Dr.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 244 pp. Englisch.
