Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The second 'African Mining' conference is planned for June 1991, and follows the first, very successful, event held in May 1987. That full four-year period was characterized by substantial changes in the political and economic climate of many countries in both hemispheres. Copper prices were relatively firm, and the advance and steady demand for nickel and ferrochromium stabilized important sectors of the mineral industry, certainly in Zimbabwe. The promise for gold remained unfulfilled, but the smaller, relatively flexible, mines survived and only the large, deep and low-value mines seem seriously at risk. None of this has affected the hungry, and intensive exploitations from surface to the water-table have revealed many targets of promise to those willing to take the risks. The pattern in Southern Africa was extraordinarily stable among the turmoil, with independence for Namibia, adjustments in South Africa and a gradual shift to market economies in the region. The pace of exploration has increased to recover some part of the progress that was lost in the Independence struggle, and atthe end of the first decade in Zimbabwe, for example, oil is being sought in the Zambesi Rift, following the investigation of the Luangwa in Zambia, and there are exciting exploration projects for methane released from coal, deep in its basins. 376 pp. Englisch.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -What can the philosophy of language learn from the classical Indian philosophical tradition As recently as twenty or thirty years ago this question simply would not have arisen. If a practitioner of analytic philosophy of language of that time had any view of Indian philosophy at all, it was most likely to be the stereotyped picture of a gaggle of navel gazing mystics making vaguely Bradley-esque pronouncements on the oneness of the one that was one once. Much work has been done in the intervening years to overthrow that stereotype. Thanks to the efforts of such scholars as J. N. Mohanty, B. K. Matilal, and Karl Potter, philoso phers working in the analytic tradition have begun to discover something of the range and the rigor of classical Indian work in epistemolgy and metaphysics. Thus for instance, at least some recent discussions of personal identity reflect an awareness that the Indian Buddhist tradition might prove an important source of insights into the ramifications of a reductionist approach to personal identity. In philosophy of language, though, things have not improved all that much. While the old stereotype may no longer prevail among its practitioners, I suspect that they would not view classical Indian philoso phy as an important source of insights into issues in their field. Nor are they to be faulted for this. 212 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The main aim of this book is to provide a concise guide to the penetrant inspection method of non-destructive testing. The emphasis is practical and is aimed at indicating how the various processes can be applied. The book begins with a survey of the history of the technology and the introduction of non-destructive testing. It goes on to discuss the penetrant process itself, its development, principles of the processes, techniques, choice of methods and the equipment that can be used. It also examines the quality control of penetrant materials and processes. The final chapters deal with health and safety and the management of penetrant waste. 236 pp. Englisch.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Despite, or perhaps better by virtue of, its very brevity, Appearance and Sense is a difficult text to read and understand, particularly if we make the attempt independently of Husserl's Ideas I. This is certainly at least in part owing to the intent behind Shpet's work. On the one hand it strives to present Husserl' s latest views to a Russian philosophical audience not yet conversant with and, in all likelihood, not even aware of, his transcendental idealist turn. With this aim any reading would perforce be exacting. Yet, on the other hand, Shpet has made scant concession to his public. Indeed, his text is even more compressed, especially in the crucial areas dealing with the sense-bestowing feature of consciousness, than Husserl' s own. For all that, Shpet has not bequeathed to us simply an abbreviated paraphrase nor a selective commentary on Ideas I, although at many points it is just that. Rather, the text on the whole is a critical engagement with Husserl' s thought, where Shpet among other things refonnulates or at least presents Husserl's phenomenology from the perspective of hoping to illuminate a traditional philosophical problem in a radical manner. Since Husserl's text was published only in 1913 and Shpet's appeared sometime during 1914, the latter must have been conceived, thought through, and written in remarkable haste. Indeed, Shpet had already finished a first draft and was busy with a revision of it by the end of 1913. 232 pp. Englisch.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This collection of papers was written for a NATO Advanced Research Workshop held at Harvard University in March 1990. The title, 'The Changing University and the Education of Scientists and Engineers: An International Workshop,' broad as it is, does not convey the sweep of data, infonnation, opinions, and suggestions for future research and policy choices that were crowded into two-and-a-half days of fonnal presentations, mealtime discussions, and teatime chats. The proposal for the workshop grew out of a research project I had carried out that explored the policies governing the education of foreign science and engineering students (S&Es) in several industrialized countries, and of two countries that send large numbers of S&E students abroad - the People's Republic of China (PRC) and Japan (see chapter 7). In research visits to these countries as well as to France, the United Kingdom, West Gennany, and within the United States, I was struck by the similarity of issues that were raised. One was the concern that there would not be enough well-trained scientists and engineers to meet the constantly increasing demand for them. Government officials, industrialists, and educators repeatedly stressed that a well-educated and -motivated work force was essential for their economies, national security, and for society as a whole. Many of those interviewed mentioned that universities are undergoing rapid, systemic changes as governments and industry are calling on them to provide human resources and intellectual capital. 196 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The rapid growth of interest in powders and their surface properties in many diverse industries prompted the writing of this book for those who have the need to make meaningful measurements without the benefit of years of experience. It is intended as an introduction to some of the elementary theory and experimental methods used to study the surface area, porosity, density, and particle size of powders. It may be found useful by those with little or no training in solid surfaces who have the need to learn quickly the rudiments of surface area, density, pore size, and particle size measurements. S.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Although, carbon is only one of one hundred plus elements, the polymer science lit erature consists primarily of studies on carbon based polymers. In part, this reflects the varied feedstock sources and in part, the type of bonds and bond forming reactions avail able to form organic polymers that are not available to the inorganic and organometallic chemist. However, recent intense interest in polymers with novel optical, electronic or magnetic properties or polymers that can serve as precursors to ceramic, semiconductor, metallic or superconductor materials has served as a driver for the development of novel synthetic routes and characterization techniques that have launched many new inorganic and organometallic oligomers and polymer systems. The following chapters represent an effort to provide an overview of several new and continuing areas of development in inorganic and organometallic polymer science. This book represents the second in a series of books we have edited on inorganic and organometallic polymer chemistry (1. Transformation of Organo-metallics into Common and Exotic Materials, NATO ASI Series Vol 141. 3. Inorganic and Organometallic Polymers with Special Properties, NATO ASI Series in press). In this series, we attempt to develop, for the reader, an understanding of the breadth, depth and potential of inorganic and organometallic polymer science. 336 pp. Englisch.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The main argument of this book is that cell signalling via nerves, hormones, local mediators and growth factors are not distinct phenomena, but branches of one general mechanism and should therefore be studied in an integrated manner. This volume is designed to act as a bridge between general texts and is aimed at biologists coming to the topic from a variety of backgrounds. The first two chapters introduce the general concepts of intracellular signalling and also cover the topic of direct cell-to-cell communication by cytoplasmic bridges (gap junctions). The remaining chapters cover the first and second messengers, starting with their structure, synthesis and release, progressing to the target cell and then working from the membrane inwards towards the nucleus. There is also a section on the mechanism of nervous conduction and the regulation of the ionic balace of cells. The final chapters discuss the regulation of cell growth and division and the special case of messengers acting via nuclear receptors. 326 pp. Englisch.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Gerald R. Faulhaber and Gualtiero Tamburini University of Pennsylvania and Universita Delgi Studi di Bologna This book brings together chapters by a group of European and North American economists, all of which focus on a single aspect of the ongoing plan for European economic integration - the role of technology. Indeed, the plan for European integration has many aspects social, institutional, and political. From a broad standpoint, the program approved by the 12 member states of the European Economic Community (Single European Act) in 1986 addresses these problems. Among other things, the Act pro vi des for the progressive establishment of a single internal market by 1992. At its most basic, this single European market means the unrestricted circulation of goods, people, services, and capital, unhindered by borders, tariffs, or restrictive national practices. The actual economic integration as planned by the Single Act will have a variety of consequences. On the whole, there will be the consolidation of the benefits already gained over the 2 Introduction previous 30 years due to the progressive lowering of tariff barriers within the Common Market. In particular, there has a been a shift away from Iimited national markets toward the wider market of the Community. In turn, this expansion of the market promises improved economies of scale and scope for many industries and a more efficient geographic allocation of production. 366 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Investigations of atmospheric pollution have recently reached a new stage. In addition to the estimation and the monitoring of pollutant concentrations in the air around their sources, by way of observational data and also by calcu lations on the basis of theoretical research, it is now possible to make short term forecasts of air pollution and to use them to regulate industrial emissions. Many countries are interested in such forecasts. In the Soviet Union the organizations of the State Committee of the USSR for Hydrometeorology (Goskomgidromet) are carrying out a wide-scale scientific programme on the devising of methods to forecast atmospheric pollution. Prognostic groups are organized in territorial hydrometeocenters; in essence a new forecasting service has been established. Nowadays, in more than 200 towns of the USSR predictions are made and transmitted to large enterprises for the purpose of taking the necessary steps to preserve air qua lity. To ensure an operative working of this service, Methodological Instruc (1979) have been issued, as well as other instructions and guides. Wide tions scale verifications of proposed calculating methods have been made. Prob lems of forecasting and regulating air pollution have become evident lately in other countries as well. Much attention to these problems is payed by the World Meteorological Organization (WMO). They have been widely dis cussed in a number of international conferences and meetings for modelling and investigating pollutant distribution in the atmosphere. The number of publications on this subject is rapidly increasing. 332 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Two different applications have been considered, automobile claims from Massachusetts and health expenses from the Netherlands. We have fit 11 different distributions to these data. The distributions are conveniently nested within a single four parameter distribution, the generalized beta of the second type. This relationship facilitates analysis and comparisons. In both cases the GB2 provided the best fit and the Burr 3 is the best three parameter model. In the case of automobile claims, the flexibility of the GB2 provides a statistically siE;nificant improvement in fit over all other models. In the case of Dutch health expenses the improvement of the GB2 relative to several alternatives was not statistically significant. \* The author appreciates the research assistance of Mark Bean, Young Yong Kim and Steve White.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Existing surfactants directories tend to focus on product identification by tradename, producer or chemical type, enabling the user only to identify product equivalents and surfactant suppliers. Application information, where available, is usually scant or given as a footnote. This new directory approaches the identification of surfactants primarily from the applications standpoint. Hence the formulator or end-user can readily assess the products available for use in a particular industry sector and select materials giving the required surface active properties. For example, a formulator of agrochemicals for crop protection can turn to the section which refers to surfactants for use in the agrochemical industry and then easily identify a wetter/dispersant system for the production of water dispersible granules. Information is presented in an alternative format in the second part of the directory, which will help the user to identify swiftly products for a particular application by surface active properties. It is difficult, if not impossible, to identify an industry which does not directly or indirectly utilise surfactants. Therefore it has proved necessary to simplify industry classifications to encompass a variety of uses under broader sector titles. The industry classifications adopted here have been used in many previous publications and papers, and define as accurately as possible the major industries and applications serviced by the surfactant industry. The editors have been particularly pleased with the support and response of the industry in the supply of data. 416 pp. Englisch.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -One of the major challenges of science in the last few years of the second millennium is learning how to design materials which can fulfill specific tasks. Ambitious as it may be, the possibilities of success are not ne~li~ble provided that all the different expertises merge to overcome the limits of eXIsting disciplines and forming new paradigms science. The NATO Advanced Research Workshop on 'Magnetic Molecular Materials' was organized with the above considerations in mind in order to determine which are the most appropriate synthetic strategies, experimental techniques of investigation, and theoretical models which are needed in order to develop new classes of magnetic materials which are based on molecules rather than on metallic or ionic lattices. Why molecules The answer may be obvious: molecular chemistry in principle fine can tune the structures and the properties of complex aggregates, and nature already provides a large number of molecular aggregates which can perform the most disparate functions. The contributions collected in this book provide a rather complete view of the current research accomplishments of magnetic molecular materials. There are several different synthetic approaches which are followed ranging from purely organic to inorganic materials. Some encouraging successes have already been achieved, even if the critical temperatures below which magnetic order is observed still are in the range requiring liquid helium. 428 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The main purpose of this book is to provide the theoretical background to engineers and scientists engaged in modeling transport phenomena in porous media, in connection with various engineering projects, and to serve as a text for senior and graduate courses on transport phenomena in porous media. Such courses are taught in various disciplines, e. g. , civil engineering, chemical engineering, reservoir engineering, agricultural engineering and soil science. In these disciplines, problems are encountered in which various extensive quantities, e. g. , mass and heat, are transported through a porous material domain. Often the porous material contains several fluid phases, and the various extensive quantities are transported simultaneously throughout the multiphase system. In all these disciplines, management decisions related to a system's development and its operation have to be made. To do so, the 'manager', or the planner, needs a tool that will enable him to forecast the response of the system to the implementation of proposed management schemes. This forecast takes the form of spatial and temporal distributions of variables that describe the future state of the considered system. Pressure, stress, strain, density, velocity, solute concentration, temperature, etc. , for each phase in the system, and sometime for a component of a phase, may serve as examples of state variables. The tool that enables the required predictions is the model. A model may be defined as a simplified version of the real (porous medium) system that approximately simulates the excitation-response relations of the latter. 580 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This conference brought together an international group of fisheries economists from academia, business, government, and inter-governmentalagencies, to consider a coordinated project to build an econometric model of the world trade in groundfish. A number of the conference participants had just spent up to six weeks at Memorial University of Newfoundland working and preparing papers on the project. This volume presents the papers that these scholars produced, plus additional papers prepared by other conference participants. In addition, various lectures and discussionswhich were transcribed from tapes made of the proceedings are included. The introductory essay explains the genesis of the conference, describes the approach taken to modelling the groundfish trade, very briefly summarizes the technical papers, and describes future plans. The project is continuing as planned, and a second conference was held in St. John's in August 1990. The conference was a NATO Advanced Research Workshop and we wish to thank the ScientificAffairs Division ofNATO for their financial support. Additional financial support was received from the Canadian Centre for Fisheries Innovation in St. John's, the Department of Fisheries and Oceans of the Government of Canada, the Department of Fisheries of the Government of Newfoundland and Labrador, Memorial University of Newfoundland and Air Nova; we acknowledge with appreciation their help. 600 pp. Englisch.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -by JULIEN IE HOFFMAN One of the earliest coronary physiologists was Scaramucci who, in 1695, postu lated that during systole the contracting myocardium inhibited coronary blood flow. Since then, the many contributions that have been made to our knowledge of the coronary circulation can be arbitrarily divided into three phases based on advances in technical methods. The early phase of research into the coronary circulation, done with great difficulty with crude methods, may be regarded as ending in the 1940s, and it included major discoveries made by such well known investigators as Georg von Anrep, Ernest Starling, Carl Wiggers, and Louis Katz, who formulated much of our basic understanding of the field. After 1940, the field of coronary physiology entered a new phase when instruments for high fidelity registration of coronary flow and pressure became available. This era was domi nated by Donald Gregg who combined careful attention to the function of these instruments (some of which he helped to develop) with an extraordinary ability to discern mechanisms from apparently minor changes in coronary flow and pressure patterns. His book 'The Coronary Circulation in Health and Disease' set a new standard in the field. After 1960, techniques for measuring regional myocardial blood flow became available, and enabled a large group of eminent investigators to make major advances in understanding the physiology and pathophysiology of myocardial blood flow. 424 pp. Englisch.
