Buch. Etat : Neu. Neuware -This paper combines data on production, on processing and formulating, on application, on the waste stream and on the possibilities for recycling polyvinyl chloride insofar as such data has relevance for an assessment of environmental impact. It is intended to help place the PVC debate on a factually well-founded basis. The paper describes many, but not all facets of the environmental effects of a common plastic. This book is based on work carried out at the Fraunhofer Institute for Systems Technology and Innovations Research and particularly on a report drawn up on the order of the Research Centre Julich (Gaensslen, H. , Sordo, M. , TOtsch, W. : Production, Processing and Recycling of PVC. Order Number 011/41072711/930, April 1989). We would like to express our thanks to Dr. Kollmann of KFA Julich for placement of this order. This book would not have come into being but for the assistance given by many colleagues. Magdalena Sordo carried out valuable preliminary work which forms the basis of many parts of the book. We would like to thank the following as representatives of our other colleagues: Eberhard BOhm for proof reading, Gunther Heger for the data base researches and Joachim Waibel for producing the illustrations. The book has been translated by H. P. Kaufmann, Technical Translations, Marketing & Advisory Services, London. We are especially grateful to Harold M. Clayton and his colleagues at Hydro Polymers Ltd for proof-reading the English manuscript. vii Contents Preface 1. 120 pp. Englisch.

Buch. Etat : Neu. Neuware -Sun, wind and water draining from the land interact with the morphological features of a water body to create the environment experienced by freshwater plants and animals. The result of this interaction can be considered as the freshwater hydro climate and this plays the same role as that of conventional climate in terrestrial ecology. Agriculture, for example, has long been supported by specialist meteorological services which not only provide farmers with a sound interpretation of weather and climate without excessive technicality but which also consider relations between climate and the growth of crops and stock. There is a need for a similar service in freshwater ecology and applied biology. This book is the result of a number of years devoted to developing part of that service. It concentrates on the influence of all forms of water movement on the ecology of fresh waters. Water movement implies interest in both the quantity of water moving through river basins which reflects the climate of the catch ment as well as the nature of the fluid motion within the rivers and lakes of the basin. The book is not so much a review of recent research as an attempt to establish a logic-how knowledge of water movement can contribute to understanding the ecology of fresh waters. Two points follow directly. 300 pp. Englisch.

Buch. Etat : Neu. Neuware -We have undertaken this volume in the belief that there is now sufficient research completed on environmental risk to justify a retrospective assessment of what is known. Our authors and our intended audience are eclectic indeed. Environ mental risk assessment receives increasing attention in the media today. The populace is practically assaulted with stories, with anecdotes, and with conflicting evidence. It is our hope that these chapters will provide the reader with a comprehensive glimpse of a fast-growing field in public policy. No complete survey of the literature would be possible or meaningful. We offer here instead the integrative thoughts of some of the most respected analysts in the field. We believe that the coverage is coherent, the perspectives are illuminating, and the individual 'treatments deserving of careful study. We are grateful to Warren Samuels of Michigan State University who is editor of the Kluwer series on recent economic thought. We are also grateful to our Kluwer editor, Zach Rolnik. Both have been gracious in their toleration of unconscionable delays.

Buch. Etat : Neu. Neuware -Concentrations of dissolved organic matter (DOM) in lakes are often an order of magnitude greater than concentrations of particulate organic matter; nevertheless, the biogeochemical analysis of DOM is described in only a few textbooks on limnology (most thoroughly by Wetzel). The orgins of dissolved organic substances are largely photosynthetic; DOM is either autochthonously synthesized by littoral and pelagic flora through secretions and autolysis of cellular contents, or allochthonously generated in terrestrial systems of the drainage basin, composing largely of humic substances refractory to rapid microbial degradation. The role of DOM in lacustrine ecosystems, as energy source and system regulator, however, is still poorly known.The aim of this book is: (1) to present state-of-the-art reviews of the role of dissolved autochthonous and allochthonous organic matter in pelagial and littoral zones; and (2) to focus attention on poorly understood but critical topics and hence to provide direction for future research activity.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 304 pp. Englisch.

Buch. Etat : Neu. Neuware -This volume contains selected papers presented at the Second Workshop on Clifford Algebras and their Applications in Mathematical Physics. These papers range from various algebraic and analytic aspects of Clifford algebras to applications in, for example, gauge fields, relativity theory, supersymmetry and supergravity, and condensed phase physics. Included is a biography and list of publications of Mário Schenberg, who, next to Marcel Riesz, has made valuable contributions to these topics.This volume will be of interest to mathematicians working in the fields of algebra, geometry or special functions, to physicists working on quantum mechanics or supersymmetry, and to historians of mathematical physics.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 540 pp. Englisch.

Buch. Etat : Neu. Neuware -This book contains chapters written by some eminent scientists and researchers on Computational Methods in Hypersonic Aerodynamics and forms a natural sequel to the earlier publications on Computational Methods in Potential Flow (1986) and Computational Methods in Viscous Aerodynamics (1990). In this book, the earlier attempts at the solution of the highly nonlinear Navier-Stokes equations are extended to the aerothermodynamics of flow in the hypersonic regime, including the effects of viscosity on the physical and chemical processes of high-temperature nonequilibrium flow at very high speeds, such as vibrational excitation, dissociation and recombination, ionization and radiation, as well as real gas effects and the effects of high temperature and low density. The book has been prepared as a valuable contribution to the state-of-the-art on computational methods in hypersonic aerodynamics. All the chapters have been written by eminent scientists and researchers well known for their work in this field.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 516 pp. Englisch.

Buch. Etat : Neu. Neuware -The method of exponential sums is a general method enabling the solution of a wide range of problems in the theory of numbers and its applications. This volume presents an exposition of the fundamentals of the theory with the help of examples which show how exponential sums arise and how they are applied in problems of number theory and its applications.The material is divided into three chapters which embrace the classical results of Gauss, and the methods of Weyl, Mordell and Vinogradov; the traditional applications of exponential sums to the distribution of fractional parts, the estimation of the Riemann zeta function; and the theory of congruences and Diophantine equations. Some new applications of exponential sums are also included.It is assumed that the reader has a knowledge of the fundamentals of mathematical analysis and of elementary number theory.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 228 pp. Englisch.

Buch. Etat : Neu. Neuware -Much of the world's forested land is dominated by mixed-species stands. Understanding the complex structure and dynamics of these mixtures is a necessary step in the process of formulating appropriate silvicultural systems for their management. David M. Smith, Professor Emeritus of Silviculture at Yale University, has devoted much of his career to the study of the structure, development, and silvicultural treatment of these kinds of stands. This volume is presented by Professor Smith's collegues to honor the contributions he has made to the field. It contains both reviews of past work and results of current studies of mixed stands: topics range from analysis of forest dynamics in unmanaged stands to studies of silvicultural systems applied to mixtures, with examples drawn from boreal, temperate, and tropical regions. Much of the work stresses the importance of understanding the characteristic growth patterns of individual species within mixed stands, and how species interactions shape developmental patterns.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 308 pp. Englisch.

Taschenbuch. Etat : Neu. Neuware -What follows is a translation of Volume X in the Husserliana series, the critical edition of the works of Edmund HusserI. I Volume X was published in 1966. Its editor, Rudolf Boehm, provided the title: Zur Phiinomen%gie des inneren Zeitbewusst seins (1893-1917). Some of the texts included in Volume X were published during HusserI's lifetime, but the majority were not. Given the fact that the materials assembled in Volume X do not constitute a single and previously published Husserlian work, some acquaintance with their history and chronology is indis pensable to understanding them. These introductory remarks are intended to provide the outlines of such an acquaintance, together with a brief account of the main themes that appear in the texts. The Status of the Texts In 1928, HusserI's 'Vorlesungen zur Phanomenologie des inneren Zeitbewusstseins' appeared in the Jahrbuch fur Philoso- I Edmund Husserl, Zur Phiinomen%gie des inneren Zeitbewusstseins (1893~1917) [On the phenomenology of the consciousness of internal time (l893~1917)I, herausgegeben von Rudolf Boehm, Husserliana X (The Hague: Martinus Nijhoff, 1966). The references in Roman numerals that occur in parentheses in this Introduction are to Rudolf Boehm's 'Editor's Introduction' to Husserliana X. References in Arabic numerals, unless otherwise noted, will be to this translation. Corresponding page numbers of Husserliana X will be found in the margins of the translation. The translation includes Parts A and B of Husserliana X, with Boehm's notes.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 472 pp. Englisch.

They fit the patho-physiologica1 processes of cardiovascular disease with fascinating precision and are a constant stimulus to the acquisition of greater understanding of the mechanisms involved and of the mode of action of the drugs themselves. There is still much to be learned, especially about the wider effects of the drugs, their precise mode and site of action and about differences between the different preparations. ACE inhibitors are of proven benefit to patients with chronic congestive heart failure and are the latest in the series of drugs used in the treatment of hypertension. Interest in the treatment of hypertension has paralleled the development of hypotensive drugs and the realisation that long-term prognosis could be significantly improved. The treatment of hypertension has progressed in stages following the development of a succession of increasingly effective drugs, each allowing a greater proportion of patients to be treated with fewer and fewer side-effects. First, the ganglion-blocking agents such as hexamethonium and guan ethidine transformed the outlook for patients with malignant hypertension but proved too unpleasant for routine use in other forms of hypertension.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 116 pp. Englisch.

Neuware -Closed-End Investment Companies (CEICs) were the dominant form of investment companies in the United States during the early part of this century, but interest in them declined after the 1929 stock market crash. Since 1985, however, there has been a significant revival of interest in CEICs.A substantial amount of academic research has focused on the nature of closed-end funds, discounts and premiums, and on the share price behavior of these firms, which often results in the prices differing from the net asset value of the shares.This book is designed for the academic researcher interested in CEICs and the practitioner interested in using CEICs as an investment vehicle. The authors summarize the evolution of CEICs, present the factors that cause CEIC shares to trade at different levels from their net asset values, provide a complete survey of the academic literature on this topic, and summarize the current state of research on CEICs.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 164 pp. Englisch.

It contains the four largest cities of the country: Amsterdam, Rotterdam, The Hague and Utrecht. The name Randstad (rim city) refers to the distinctive shape of the conurbation, a horseshoe of cities around an open agricultural and recreational area, known as the Green Heart.This book analyzes the restructuring of the region. The volume summarizes the research of the Urban Networks research program. The discussion is focused on four themes: housing, labor market and employment, infrastructure and transportation, and the provision of public services. The Randstad is internationally known as the playground of urban and regional planners. Their debates on present policy issues are extensively reviewed in the book.Teachers and students of urban change and planning, and policy makers and planners in The Netherlands and abroad will find much valuable information in this book.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 280 pp. Englisch.

Complaints about poor IAQ, associated with acute symptoms such as mucous irritation, headaches and bad odor occur frequently, particularly in the office environment, where typical patterns of symptoms often occur, leading to the coining of the term `Sick Building Syndrome'.In the present book, internationally known experts address the following issues: the dynamics of the indoor environment and strategies for indoor measurementchemical and microbiological pollution, important species, sources and detection methodseffects of indoor pollution, in particularsensory irritation, including odorairway, eye and skin irritation by organic indoor pollutants and their assessmentimmune effects, including allergic sensitizationchemical hyper-responsivenesscontrolled human reactions to organic pollutantsbuilding investigation: approaches and resultssource characterization and controlcriteria, norms and techniques in indoor air pollution, and regulatory aspects.The complex, multifactorial nature of sick building syndrome requires multidisciplinary collaboration from very diverse fields. It is evident that communication between researchers coming from very different areas, all speaking their own language, is a difficult task. This book, presenting as it does the state of the art on sick buildings and how to cure them, is a sound foundation on which to build for the future. 392 pp. Englisch.

Neuware -An increasing variety of biological problems involving resource management, conservation and environmental quality have been dealt with using the principles of population biology (defined to include population dynamics, genetics and certain aspects of community ecology). There appears to be a mixed record of successes and failures and almost no critical synthesis or reviews that have attempted to discuss the reasons and ways in which population biology, with its remarkable theoretical as well as experimental advances, could find more useful application in agriculture, forestry, fishery, medicine and resource and environmental management. This book provides examples of state-of-the-art applications by a distinguished group of researchers in several fields. The diversity of topics richly illustrates the scientific and economic breadth of their discussions as well as epistemological and comparative analyses by the authors and editors. Several principles and common themes are emphasized and both strengths and potential sources of uncertainty in applications are discussed. This volume will hopefully stimulate new interdisciplinary avenues of problem-solving research.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 308 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This conference provides a forum for exchange of technical and operational information across a wide range of pipeline activities. Various supply and distribution industries, and their service organisations, have traditionally approached pipeline systems from many different perspec tives. The organisers believe that significant benefits can be gained by enabling representatives from the oil, gas, water, chemical, power and related industries to present their latest ideas and methods. An awareness of these alternative methodologies and technologies should result in a more unified and coherent approach to each individual type of pipeline system. The overall theme of the conference is the optimisation of pipeline systems, through design analysis, component specification, operational strategies and performance evaluation, in order to minimise both risk and the lifetime cost of ownership. Wherever possible emphasis is given to important developing technologies with special consideration to use of computational equipment and methods. SYSTEMS APPROACH For the major activities of design, operation and performance; pipeline systems can be conveniently classified in terms of the systetV: components, constraints and objectives. These are described using fluid terminology, to suit' the majority of conference participants, as given below: Components consist of pumps and valves (controls), pipe networks (transmission and distribu tion), reservoirs (storage) and consumer demands (disturbances). The arrangement of these components, to form the system, must take into account the conflicting requirements of structural, hydraulic, and cost, performance. 352 pp. Englisch.

Neuware -The plasma membrane is at once the window through which the cell senses the environment and the portal through which the environment influences the structure and activities of the cell. Its importance in cellular physiology can thus hardly be overestimated, since constant flow of materials between cell and environment is essential to the well-being of any biological system. The nature of the materials mov ing into the cell is also critical, since some substances are required for maintenance and growth, while others, because of their toxicity, must either be rigorously excluded or permitted to enter only after chemical alteration. Such alteration frequently permits the compounds to be sequestered in special cellular compartments having different types of membranes. This type of homogeneity, plus the fact that the wear and tear of transmembrane molecular traffic compels the system to be constantly monitored and repaired, means that the membrane system of any organism must be both structurally complex and dy namic. Membranes have been traditionally difficult to study because of their fragility and small diameter. In the last several decades, however, remarkable advances have been made because of techniques permit ting the bulk isolation of membranes from homogenized cells. From such isolated membranes have come detailed physical and chemical analyses that have given us a detailed working model of membrane. We now can make intelligent guesses about the structural and func tional interactions of membrane lipids, phospholipids, proteins, sterols and water. 284 pp. Englisch.

Neuware -In these last years Black hole Physics has developed rapidly both from theoretical and observational aspects: especially as regards quantum aspects many things must be clarified as for instance the processes occuring near mini black holes with spontaneous creation of particles that eventually lead to the evaporation of black hole. In these last stages probably a connection with string theory will appears. This field of research was subject of the NATO Adavanced study Institute on 'Black Hole Physics' which was held at the Ettore Majorana Center for Scientific Culture in Erice (Sicily, th Italy) from May 12th through May 22 , 1991. It was at the same time the 12th Course of the International School of Cosmology and Gravitation. During this 12th Course, after recalling the starting point that is the concept of black hole in Newton theory, the lectures are gone through classical, quantum, cosmological and astrophysical aspects. Of course in order to understand fully the behaviour of these objects one is faced with a large number of broad areas related to different branches of physics. In fact have been widely treated not only classical aspects, thermodynamics, entropy, internal dynamics, cosmology, inflation and astrophysics but quantum behaviour involving creation of particles, Hawking rad iation, until the modern theory of strings and superstrings that claims the unification of all interactions. So the physics involved and discussed in the various lectures goes from cosmology and very early universe to that of elementary particles including neutrino physics.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 440 pp. Englisch.
