Taschenbuch. Condizione: Neu. Neuware -Early one morning in April of 1987, the Chinese mathematician J. -Q. Zhong died unexpectedly of a heart attack in New York. He was then near the end of a one-year visit in the United States. When news of his death reached his Chinese-American friends, it was immediately decided by one and all that something should be done to preserve his memory. The present volume is an outgrowth of this sentiment. His friends in China have also established a Zhong Jia-Qing Memorial Fund, which has since twice awarded the Zhong Jia-Qing prizes for Chinese mathematics graduate students. It is hoped that at least part of the reasons for the esteem and affection in which he was held by all who knew him would come through in the succeeding pages of this volume. The three survey chapters by Li and Treibergs, Lu, and Siu (Chapters 1-3) all center around the areas of mathematics in which Zhong made noteworthy contributions. In addition to putting Zhong's mathematical contributions in perspective, these articles should be useful also to a large segment of the mathematical community; together they give a coherent picture of a sizable portion of contemporary geometry. The survey of Lu differs from the other two in that it gives a firsthand account of the work done in the People's Republic of China in several complex variables in the last four decades.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 500 pp. Englisch.

In the work accom plished since that time, research has been greatly expanded on fission products and has been extended to many nuclides formed in the fission of various nu clei induced by neutrons, gamma rays, charged particles, and in spontaneous fission. Amassing of experimental results is an important task not only for nu clear engineering but also for an understanding of the fission process itself, for bringing into existence a finished theory on the unique and intriguing physi cal phenomenon which plays such a decisive role in the practical utilization of nuclear energy. In this reference manual, an attempt is made to collect and generalize upon the results of experimental research work over the period spanning 1939 to 1962, on yields of fission products and on the mass distribution of fission fragments. Various instances of the fission of nuclei induced by neutrons, gamma rays, charged particles, and spontaneous fission of nuclei are discussed.

Some of these problems (e.g., the pur ity of natural waters and air) have attracted the attention not only of specialists but also of society generally. It would be impossible to do research on trace components and contaminants if we did not have reliable rapid and sensitive methods of determining substances present in mixtures in minute concentrations. Gas chromatography is an effective method of purity testing. This book deals with analysis for trace components, together with the basic methods of gas chromatography that are used for the purpose. We have tried to reflect here the principal papers in this area appearing in the foreign literature and in Rus sian. Weare indebted to Plenum Pre~'B for the opportunity of pre senting this edition. Moscow September 1972 v Preface Gas -chromatographic analysis for impurities is presently a rapidly developing area in gas chromatography, because many practical topics give considerable importance to impurity analy sis. Progress in this analysis bas been such for volatile com pounds (and also for nonvolatile ones, when reactive gas chroma tography is used) that one can now be confident of solving most practical problems in this way. Commercial ionization detectors of high sensitivity and selectivity often allow one to detect impuri ties down to levels of parts in 109.

Luriya provides us for the first time with a comprehensive review of the massive amount of work carried out in the USSR in this important area of biological research. Historically, the pioneering tissue culture studies of Maksimov, Popov, Chasovnikov, and their colleagues working in Russia in the early part of this century provided much of the impetus for subsequent studies on lymphopoiesis and hematopoiesis in vitro and much of the basic information used subsequently to achieve immune responses in vitro and to develop the methodology for cloning hematopoietic stem cells. Particularly welcome in this translation is the addition of the Appendix, in which Drs. Luriya and Fridenshtein describe in some detail the methodology that has been developed in their laboratories for the study of a variety of cell types in cell and tissue culture. For many of us, this description provides information that had previously not been accessible to us: porosity of millipore fIlters in relation to growth properties; colony-forming cell adhesiveness; pro liferation kinetics of stromal cells; differential effectiveness of various media used for culture of liver cells; details of washing procedures for fIlter substrates used in culture.

Druck auf Anfrage Neuware - Printed after ordering - In the ten years since the first publication on PCR (Saiki et al. , 1985), this in vitro method of nucleic acid replication and modification has grown to rival in popularity traditional microbiological, genetical und technical procedures for cloning, sequencing, gene detecting and related procedures. To date the PCR literature has emphasized six main areas of application: genetic mapping, detection of mutations, genetic polymorphism, transcriptional splicing and regulation, molecular virology and quantitative procedures. The overwhelming focus of quantification of DNA or RNA by PCR has been on human microbiology and oncological problems. The exquisite sensitivity of PCR gives this method the ability to detect extremely rare DNAs, mRNAs, mRNAs in small numbers of cells or in small amounts of tissue, and mRNAs expressed in mixed-cell populations. However, the exact and accurate quantification of specific nucleic acids in biological samples is in spite of numerous publications in that field still a general problem: during the peR process, an unknown initial number of target sequences are used as a template from which a large quantity of specific product can be obtained. Although the amount of product formed is easy to determine, it is difficult to deduce the initial copy number of the target molecule because the efficiency of the peR is largely unknown.

Dane (`Duke') Picard takes the reader on journeys across deserts, mountains, canyons, and rivers from the American Southwest to Italy and France. His blend of vivid description and humor evokes the rugged days of field petroleum geology in the Great Plains and pastel Badlands of Utah and Wyoming in the 1950s and later days unlocking the geological secrets of sandstone in the Rockies. Along the way, he pokes gentle fun at the academic life in stories that will make anyone smile who's ever sat on a faculty committee or chaired a professional meeting. The final essays on his travels through Provence and Italy are rich with details of the beauty and the history - both human and geological - of the regions. M.D. Picard is the author of numerous professional articles and books, and has served as president of the National Association of Geology Teachers, the Society of Sedimentary Geology, and the Rocky Mountain section of the American Association of Petroleum Geologists. He is well known to the geological community for the essays and book reviews he has published over the last ten years in geoscience journals and magazines.

Druck auf Anfrage Neuware - Printed after ordering - The first time that we, the editors of this volume, met, a chance remark by one of us, newly returned from fieldwork in Fiji, quickly led to an animated discussion of our experiences doing anthropological research with children. Following that occasion, we began to seek each other out in order to continue such conversations, because we had found no other opportunity to discuss these significant events. We knew our experiences were rich sources of cross-cultural data and stimuli to rethinking anthro pological theory and methods. A cursory review of the literature on fieldwork revealed, to our surprise, that fieldworker's experiences with children were rarely and only briefly mentioned (Hostetler and Huntington, 1970, are an early exception). In order to learn more about research that included the ethnographers' children, we organized a conference on the topic at Michigan State University on May 1, 1982. This volume includes papers from that conference, as well as insights and ideas from the formal and informal discussions among the conference participants and audience. This volume, like the conference which preceded it, is intended to be the effects of accompanying children on anthropological an exploration of field research and on the effects of fieldwork on the children themselves. Additionally, we see this book as part of an anthropological inquiry into research as a cultural process, by which is meant the effects of the researchers' cultural identity--class, gender, age, ethnicity, and other characteristics--on fieldwork.

Thethemeofthe Federal T Reserve BankofDallas' second annual conferenceon the Southwesteconomy, 'The 1990s: A Different Decade,' reflected our belief that the beginning ofthe new decade would mark a turn toward economic strength in the Southwest. The conference, held Oct. 26-27, 1989, at Loews Anatole Hotel in Dallas, Texas, brought together more than 250 interested individuals and speakers for anexchangeofinformationand ideas. Topics rangedfrom the currentcondition of the Southwest economy to the factors shaping the future. Theinfluences on the Southwest economy are diverse but interrelated. For example, the Southwest faces a complex dilemma in reforming its educational system. As conference speakers illustrated many times, education reform and the quality ofour schools are closely linked to the region's, if not the nation's, ability to compete in future world markets. These proceedings follow the basic organizational pattern of the confer ence. Keynote and luncheon addresses appear in the first section, General Meetings-The 1990s: ADifferent Decade, which includes speeches by Bobby R. Inman, admiral, United States Navy (retired), and private investor; Robert H. Boykin, president and chief executive officer of the Federal Reserve Bank of Dallas; WilliamH.

Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - This set of lectures is the outgrowth of a new course in the Department of Materials Science at Stanford University. It was taught collectively by the authors of the various sections and represents an attempt to increase the awareness of students in the materials area of computer simulation techniques and potentialities. The topics often ranged far afield from the materials area; however, the total package served the intended purpose of being an initiation into the world of computer simulation and, as such, made a useful first iteration to the intended purpose. The second iteration, which is in process, deals exclusively with the materials area. The course was designed to teach students a new way to wrestle with 'systems' problems in the materials science work area that require the synthesis and interactions of several disciplines of knowledge. This course was a response to the realization that effective handling of real problems, which are essentially systems problems, is one of the most important at tributes of a graduate materials scientist. About a third of the course was devoted to the student's selected problem, in the materials area, which he simulated using the digital computer.

Druck auf Anfrage Neuware - Printed after ordering - In recent years many research workers have turned their attention to the quantitative characterization of complex compounds and reactions of complex-formation in solution. Instability constants characterize quantitatively the equili bria in solutions of complex compounds and are extensively used by chemists of widely-varying specialities, in analytical chemistry, electrochemistry, the technology of non-ferrous and rare metals, etc., for calculations of various kinds. Despite the wealth of numerical data, no reasonably full coliection of instability constants of complex compounds has been made until now. The various individual collections of data are far from complete and in most cases omit references to the source materials. Moreover, the present state of the chemistry of complex compounds most urgently demands the complete systematization of data on instability constants and an extension of work in this field which would take advantage of the latest physico-chemical methods. The present work contains instability constants for 1,381 complex compounds. We have considered it convenient to preface the summary of the instability constants with an introductory section of a general theoretical character. This section deals with methods for the calculation of instability constants from experimental data, the influence of external conditions, such as temperature and ionic strength, on the stability of com plexes, and the principal factors determining the stability of complex compounds in aqueous solution. (vii) PREFACE In compiling the summary we have used the original litera ture and abstracts for the most part up to 1954, and some work published in 1955-1956.

Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - March 10, 1964 The problem of friction and wear between solid bodies is about as old as the human race. The early Egyptians and Romans had discovered the utility of lubricants in reducing friction and wear during a period many years B. C. From the fall of the Roman Empire until the Renaissance, I ittle new information appeared. A major break-through occurred in establ ishing the laws of friction (friction independent of area and proportional to load) through the work of Leonardo da Vinci (1452 - 1519), Amontons (1699) and Coulomb (1785). While most of the studies until this time were based largely on a mechanistic approach, a new trend was initiated in the 1930's by F. P. Bowden and D. Tabor wherein the physics and chemistry of the problem were treated as well. Since then, a large I iterature has been buil t up deal ing with such problems as metal transfer, molecular theories to explain wear, local welding between contacting surfaces, interlocking theories, wear-rate studies, the development of various test methods, effects of surface films, fretting phenomena, effects of temperature and environmental conditions, abrasion, surface energy relations, etc. The I ist of contributors in this field is indeed too long to cite here in any detail. Among those that might be mentioned, however, are R. Holm, G. A. Tomlinson, H. Ernst, M. E. Merchant, 10M. Feng, J. K. Lancaster, W. Hirst, F. T. Burwell, D. W. Baker, F. D. Brailey, E. R.

The issues discussed in this work reflect issues that arose on a recurring basis with clients participating in HIV research studies, with investigators calling for guidance on the legal implications of particular aspects of their proposed studies, and with research institutions and health care facilities struggling to make sense of legal maneuvers aimed at obtaining the records of their HIV-infected patients. It is impossible to thank each of these persons individually for their provocative questions and their insights. The discussion of ethical and legal issues relating to the design of clinical trials reflects questions raised during discussions with Donald J. Slymen, Ph.D. Don was one of the first researchers, in my realm of experience, to pay close attention to ethical concerns, and I am greatly appreciative of his contribution to both my professional growth and the development of various scenarios discussed in this text. The portions of this text dealing with confidentiality are the result of many hours of thoughtful discussion and analysis with Penn Lerblance, J.D., now deceased and still missed. Penn and I often participated together as presenters of in-service training programs for health prof- sionals. Penn addressed discrimination, and I focused on confidentiality.

Druck auf Anfrage Neuware - Printed after ordering - Mobile Channel Characteristics introduces the principal transmission phenomena of mobile and personal communication - the ones that affect design of modems, channel simulators, smart antennas, and other system components at the physical level. It is designed to be accessible to senior undergraduates, as well as graduate students and working engineers. The treatment parallels mathematical derivations with intuitive explanations and simple approximations in order to develop the reader's understanding of the phenomena. Because of this strong tutorial flavor, the text is also suitable for those entering the area from a different academic discipline. Mobile Channel Characteristics was conceived and written as an interactive text to be viewed on a computer screen. It includes many features not found in conventional texts: The entire text resides on your hard drive. It is always ready, just a mouse-click away; It is a live document. Try different parameter values, and the equations, tables and graphs recalculate as you watch. Animated graphics illustrate dynamics of the channel. Explore propagation, modulation or system models interactively to gain additional insight; The examples and appendices are `tear-off design sheets'. You can use their programs on the job or in your thesis to speed up your work; It links you to the world. Hyperlinks connect you to websites of cited authors, to online research journals, and to employers and graduate schools, all through the Internet. Mobile Channel Characteristics includes working programs for three different methods of channel gain generation for fading channel simulation, as well as working programs to illustrate their use. Mobile Channel Characteristics is an essential reference tool for practising engineers, researchers, academics, and students. It is a self-study text equally suited for classroomuse.

The special feature of these proceedings was two systematic series of lectures, one by F. Pham of C.E.N., Saclay and CERN, Geneva and the other by G. Rickayzen of the University of Kent, Canterbury. Pham dwelt at length on the applications of the methods of alge braic topology and differential forms to the study of the analytic properties of S-matrix theory, in particular, with reference to the location of singularities of the multiple scattering processes. This exposition was a natural sequel to the lectures of V. L. Teplitz, pub lished in an earlier volume of this series. Rickayzen discus.sed in detail the latest theory of superconductivity. Other lectures were those of Scadron, who dealt with some formal features of potential scattering theory, and B. M. Udgaonkar and A. N. Mitra, who spoke on certain aspects of bootstraps and quark models, respectively. The contributions in pure mathematics in this volume include two lectures by S. K. Singh, one on the field of Mikusinski operators and another on Riemann mapping theorem, and a lecture on cosine func tionals by P. L. Kannappan. One of the highlights of the symposium was a lecture by S. K. Srinivasan who is keeping alive the interest of the Madras group in the theory of stochastic processes and who, in particular, has enlarged the domain of the application of the theory of product densities.

In either case, understanding of the interactions between trade and the environment will be vital. Trade and the Environment presents both the theoretical and empirical exposition of (i) the impact of trade liberalization on environmental quality; (ii) the impact of environmental regulations on international competitiveness; and (iii) strategic trade and environmental policies. An important feature of Trade and the Environment as compared to earlier books is that it brings together the reciprocal interactions between trade and the environment. It can be used as the main or complementary textbook for a course on trade and the environment.

Druck auf Anfrage Neuware - Printed after ordering - The development of contemporary molecular biology with its growing tendency toward in-depth study of the mechanisms of biological processes, structure, function, and identification of biopolymers requires application of accurate physicochemical methods. Electrophoresis occupies a key position among such methods. A wide range of phenomena fall un der the designation of electrophoresis in the literature at the present time. One common characteristic of all such phenomena is transport by an elec tric field of a substance whose particles take on a net charge as a result of interaction with the solution. The most important mechanisms for charge generation are dissociation of the substance into ions in solution and for mation of electrical double layers with uncompensated charges on particles of dispersed medium in the liquid. As applied to the problem of separation, purification, and analysis of cells, cell organelles, and biopolymers, there is a broad classification of electrophoretic methods primarily according to the methodological charac teristics of the process, the types of supporting media, etc. An extensive literature describes the use of these methods for the investigation of differ ent systems. A number of papers are theoretical in nature. Thus, the mi croscopic theory has been developed rather completely [13] by considering electrophoresis within the framework of electrokinetic phenomena based on the concept of the electrical double layer.

Accordingly, most investigators are not aware of the work of their Chinese colleagues in this field. Yet the field has been an active if small one in China, and has covered a variety of topics that include electrophysiology, neurochemistry, neuropharmacology, neuropsychology, and in strumentation. Standard techniques and instruments, a number of Chinese manufacture, have been employed. Moreover, Chinese workers have been quite familiar with the publications of other investigators, as is readily apparent from the bibliographies of the papers (see Index).

Sharp scientific criticism and strictly controlled experimental studies reject most of the hypotheses, leaving behind only a small number of assumptions and ideas. Nevertheless, each logical assumption should have its rightful place on the scientific 'battlefield' supposed to assess its validity and determine its final fate. Even when a hypothesis is wrong, it still finds its place in the entire efforts of the humankind towards attaining the scientific truth. Namely, the wrong hypotheses serve largely to illuminate the way towards the correct ones or, at least, to show which way not to follow. Correct or not, ideas and hypotheses are necessary for the progress of science. They epitomize the efforts of human thought to elucidate nature without experimental verification and in the circumstances of scant data availability. Finally, hypotheses and ideas represent a symbiotic creation of our knowledge and imagination, the two most impressive appearances in the evolution of humans.

This author, in his capacity as a geologist, air photo interpreter, and surveyor, has been asked to consult on very simple tasks that should be a part of the general knowledge of nearly everyone in the building trades. There is a definite and clear need for a short, simple, well-illustrated, and concise book that treats problems encountered every day by people in the field, and for training such people. This is such a book. The primary aim of the book, then, is not to write about new knowledge in the areas of photogrammetry or mathematics, or to discuss the latest procedures in using complex electrooptical surveying devices, but to give the common, everyday worker in the field (and there are many of them) some assistance and guidance.

The use of GST in this book is in sharp contrast to previous attempts. It addresses structural problems totally based on qualitative, non-numerical mathematics. The book lays a framework for initial efforts to investigate the potential of using formal GST to address organizational dilemmas. The text has been tested in several graduate courses. It can serve as an excellent textbook or reference for graduate level research in this field, as well as a reference for researchers in related fields.

Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - Asymptotic methods belong to the, perhaps, most romantic area of modern mathematics. They are widely known and have been used in me chanics, physics and other exact sciences for many, many decades. But more than this, asymptotic ideas are found in all branches of human knowledge, indeed in all areas of life. In this broader context they have not and perhaps cannot be fully formalized. However, they are mar velous, they leave room for fantasy, guesses and intuition; they bring us very near to the border of the realm of art. Many books have been written and published about asymptotic meth ods. Most of them presume a mathematically sophisticated reader. The authors here attempt to describe asymptotic methods on a more accessi ble level, hoping to address a wider range of readers. They have avoided the extreme of banishing formulae entirely, as done in some popular science books that attempt to describe mathematical methods with no mathematics. This is impossible (and not wise). Rather, the authors have tried to keep the mathematics at a moderate level. At the same time, using simple examples, they think they have been able to illustrate all the key ideas of asymptotic methods and approaches, to depict in de tail the results of their application to various branches of knowledg- from astronomy, mechanics, and physics to biology, psychology and art. The book is supplemented by several appendices, one of which con tains the profound ideas of R. G.

Druck auf Anfrage Neuware - Printed after ordering - While working as a chromatographer in the pharmaceutical industry, it became apparent to the editor that there was a pressing need for a comprehensive reference text for analysts working on the resolution of enantiomers by liquid chromatography (LC). This need arises from the fact that, whereas previously it was very difficult to determine enantiomers by direct means, there is now a wide choice of direct LC methods. At the same time, regulatory authorities have been changing their attitudes towards the administration of pharmaceuticals as racemates, partly because it is now possible to study the individual enantiomers. Clearly this abundance of new information needs to be rationalized. More importantly, the chiral LC systems which are commercially available or readily accessible to the practising chromatographer needed to be reviewed and, to a much greater extent than in existing reviews or books, discussed in terms of their practical application. Accordingly this book is very much orientated towards the practical aspects of these commercially available and readily accessible chiral LC systems. To this end, it is written for practising chromatographers by a team of practising, experienced chromatographers who have spent many years tackling the problems presented by resolving enantiomers by LC.
