Taschenbuch. Condición: Neu. Neuware -Astronomy with a Budget Telescope, 2nd Edition is a complete introduction to buying and using a low-cost amateur astronomical telescope. It provides essential hints and tips about what to look for when buying on a budget - the best are now excellent value, but they all lack an astronomer's advice about setting them up and using them.Astronomy with a Budget Telescope was first published in 2003, since then technology has moved on substantially. The main factors are first the availability of fairly inexpensive computer-controlled 'go-to' telescopes which after setting up can automatically locate any celestial objects with reasonable accuracy. Second, digital cameras have now almost completely displaced 'wet' film cameras, and some of them are particularly well-suited to astronomical use. Third, prices are down and quality is up!This new edition is revised and extended to include using a low-cost 'go-to' telescope - there are various pitfalls to be avoided - and how this class of instrument can make amateur astronomy more accessible to those with limited time at their disposal. It also discusses the new breed of mid-range digital cameras that include powerful on-board processing and image enhancement software that used to be available only to people with advanced astronomical CCD cameras.Finally, there are detailed reviews and test reports on some of the budget telescopes that are available on Main Street and by mail order.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 176 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -The Subject A little explanation is in order for our choice of the title Linear Opti- 1 mization (and corresponding terminology) for what has traditionally been called Linear Programming.Theword programming in this context can be confusing and/or misleading to students. Linear programming problems are referred to as optimization problems but the general term linear p- gramming remains. This can cause people unfamiliar with the subject to think that it is about programming in the sense of writing computer code. It isn¿t. This workbook is about the beautiful mathematics underlying the ideas of optimizing linear functions subject to linear constraints and the algorithms to solve such problems. In particular, much of what we d- cuss is the mathematics of Simplex Algorithm for solving such problems, developed by George Dantzig in the late 1940s. The word program in linear programming is a historical artifact. When Dantzig rstdevelopedthe Simplex Algorithm to solvewhat arenowcalled linear programming problems, his initial model was a class of resource - location problems to be solved for the U.S. Air Force.

Taschenbuch. Condición: Neu. Neuware -With the increasing popularization of personal hand-held mobile devices, more people use them to establish network connectivity and to query and share data among themselves in the absence of network infrastructure, creating mobile social networks (MSNet). Since users are only intermittently connected to MSNets, user mobility should be exploited to bridge network partitions and forward data. Currently, data route/forward approaches for such intermittently connected networks are commonly 'store-carry-and-forward' schemes, which exploit the physical user movements to carry data around the network and overcome path disconnection. And since the source and destination may be far away from each other, the delay for the destination to receive the data from the source may be long. MSNets can be viewed as one type of socially-aware delay tolerant networks (DTNs). Observed from social networks, the contact frequencies are probably different between two friends and two strangers, and this difference should be taken into consideration when designing data dissemination and query schemes in MSNets. In this book, the fundamental concepts of MSNets are introduced including the background, key features and potential applications of MSNets, while also presenting research topics, such as, MSNets as realistic social contact traces and user mobility models. Because the ultimate goal is to establish networks that allow mobile users to quickly and efficiently access interesting information, particular attention is paid to data dissemination and query schemes in subsequent sections. Combined with geography information, the concepts of community and centrality are employed from a social network perspective to propose several data dissemination and query schemes, and further use real social contact traces to evaluate their performance, demonstrating that such schemes achieve better performance when exploiting more social relationships between users.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 96 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -¿The purpose of this book is to provide a hands-on guide to finance and investment for academics with an objective of providing strategies to maximize income, minimize fees, and legally minimize taxes. There are many risks in finance and investment such as stock market crashes, inflation, corruption, fees and interest rates. This book stresses that stocks and bonds are the mainstay of most investors. Dividend-growthstocks mitigate the risk of inflation. In addition, they cost nothing once they are purchased, unlike mutual funds that have constant fees. The author explains how to find dividend-growth stocks whose payout increase exceeds inflation and how to compound quarterly in order to make projections for future growth in the number of shares or in the value of the capital itself. The author, in addition, discusses the valueof bond funds and master-limited partnerships for an investment portfolio. Retirement income is a major concern for senior academics and the median level of retirement savings for those 55 to 64 is only $145,000, which is insufficient. The author stresses the need to mix dividend-growth stocks and closed-end bond funds to fund retirementas well as explains Roth IRAs, 401(k)s and other such tax-free forms ofretirement financing. Finally, the book examines financial risks and shows how to mitigate them to the extent possible. This book is a must-have for any professor or academic approaching retirement age or looking to secure their future income.¿Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 144 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -Sugarcane, an important source of sugar, plays a substantial role in world economy. As a C4 plant this has very efficient system for carbohydrate metabolism through photosynthesis. Crop improvement efforts have concentrated mainly on improving quality traits, mainly sugar content. This being a complex trait, involves a large number of target genes in the metabolic pathway. The complex polyploid nature of the crop makes it more difficult to pin point the key players in this complex pathway.Despite its importance, little is known about the exact mechanism of sucrose accumulation and its regulation in sugarcane. Many enzymes have been proposed to have a key role in determining the ultimate sucrose content in sugarcane. There are evidences to show that some of these like Sucrose Phosphate Synthase (SPS) and Sucrose Synthase (SuSy) are encoded by multiple genes that show organ specifity in sugarcane. Especially in a crop like sugarcane where the classical techniques are of limited help in elucidating various genetic complexities, molecular techniques can be of help in throwing some light on the grey areas. Molecular marker strategies will be of help in understanding some aspects of sucrose metabolism and its regulation in this crop, thus complementing the ongoing crop improvement programmes.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 60 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -¿¿At a time when rates of depression and other mental health problems are increasing significantlyamong high school students, measures of school attitude and well-being are of central importance to school practitioners. Students with positive attitudes about school experience more beneficial outcomes and are also less likely to engage in maladaptive, risky behaviors. Therefore, monitoring how students feel about their experiences at school is important, and a novel, fresh approach to examining school attitude is sorely needed.Past studies of school attitude have generally focused on internal, psychological correlates of school attitude, such as individual and subjective reports of students¿ attitude toward school and their motivation levels. Evaluating and Promoting Positive School Attitude in Adolescents goes beyond these traditional measurements and explores less psychologically focused indicators, including ecological factors and observable behaviors. This study provides school psychologists with a new, comprehensive, and ecologically based approach with which to evaluate the school attitude of high school students.¿Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 64 pp. Englisch.

Buch. Condición: Neu. Neuware -Stochastic Optimal Control (SOC)¿a mathematical theory concerned with minimizing a cost (or maximizing a payout) pertaining to a controlled dynamic processunder uncertainty¿has proven incredibly helpful to understanding and predicting debt crises and evaluating proposed financial regulation and risk management.Stochastic Optimal Control and the U.S. Financial Debt Crisisanalyzes SOC in relation to the 2008 U.S. financial crisis, and offers a detailed framework depicting why such a methodology is best suited for reducing financial risk and addressing key regulatory issues. Topics discussed include the inadequacies of the current approaches underlying financial regulations, the use of SOC to explain debt crises and superiority over existing approaches to regulation, and the domestic and international applications of SOC to financial crises. Principles in this book will appeal to economists, mathematicians, and researchers interested in the U.S. financial debt crisis and optimal risk management.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 176 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -Politicians, social scientists, entrepreneurs, trade unionists, church leaders, philosophers, all of us in fact have caused such vast vague ness and confusion about the term 'power' that this can hardly be attributed to mere chance. Apparently, there is so much at stake, whenever we think about power or are involved, that it may be worth our while to keep the concept blurred. This is most clearly seen in social science. Power, inequality in power, struggle for power are a kind of prime movers in social life, but power problems have seldom been studied, compared to the research done on other subjects, such as satisfaction about personal achievement, perception, mental processes, achievement motivation, cultural differences, etc. Power appears to be under a taboo in society and most social scientists agree not to discuss it (ref. 23, pp. 55 and 56). Whatever research there has been reveals the peculiar trend of restricting itself to the study of power differences and power struggles as world- or macro-problems. Studies of mondial problems have covered rela tions between America and the Soviet Union, or between rich and poor countries. China has also been included of late. The studies on macrostructural problems will cover subjects like the power of particular groups within the nation, such as retired army generals and politicians working in various sectors of trade and industry (ref. 21, pp. 11 and 281), or the number of representatives of large banks on the advisory boards of other companies (ref. 22).Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 108 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -Giving on occasions a talk on the subject of this book, one of the queries raised was, 'surely, what you mean are flat hierarchies'. This, I think, gives an indication of how difficult it can be to conceive of organizations which do not have a hierarchical structure. A rather similar response was obtained when, in the 1950's, an account was given to a manager of the British Coal Board of an autonomous composite team of more than 40 miners, who had taken over complete responsibility for a three-shift cycle, and divided the income obtained among themselves. His comment was that this could not possibly work. The new mode of work organization which had been evolved by the miners in several pits in the Durham coal fields was, at the time, well ahead of the prevailing concepts and philosophy of both management and the Trade Union. It did not help matters very much that the detailed accounts were presented in an academic and scientific form (Trist et aI. , 1963; Herbst, 1962). I think that we felt that all the backing of systematic research and data analysis would be needed to present the case for modes of organization, which deviated from conventional practice. However, something was learned from this experience. When at the beginning of the 1960's the Norwegian Work Democratization Project was started, a number of demonstration sites were set up which people could look at, and which could function as centers for diffusion.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 124 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -\* The present work is designed to provide a practical introduction to aqueous equilibrium phenomena for both students and research workers in chemistry, biochemistry, geochemistry, and interdisciplin ary environmental fields. The pedagogical strategy I have adopted makes heavy use of detailed examples of problem solving from real cases arising both in laboratory research and in the study of systems occurring in nature. The procedure starts with mathematically complete equations that will provide valid solutions of equilibrium problems, instead of the traditional approach through approximate concentrations and idealized, infinite-dilution assumptions. There is repeated emphasis on the use of corrected, conditional equilibrium constants and on the checking of numerical results by substitution in complete equations and/or against graphs of species distributions. Graphical methods of calculation and display are used extensively because of their value in clarifying equilibria and in leading one quickly to valid numerical approximations. The coverage of solution equilibrium phenomena is not, however, exhaustively comprehensive. Rather, I have chosen to offer funda mental and rigorous examinations of homogeneous step-equilibria and their interactions with solubility and redox equilibria. Many examples are worked out in detail to demonstrate the use of equi librium calculations and diagrams in various fields of investigation.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 268 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -This book contains the Proceedings of the S~cond U. S. -Japan Seminar on Learning Control and Intelligent Control. The seminar, held at Gainesville, Florida, from October 22 to 26, 1973, was sponsored by the U. S. -Japan Cooperative Science Program, jointly supported by the National Science Foundation and the Japan Society for the Promotion of Science. The full texts of the twenty-one presented papers are included. The papers cover a variety of topics related to learning control and intelligent control, ranging from pattern recognition to system identification, from learning control to intelligent robots. During the past decade, there has been a considerable increase of interest in problems of machine learning, systems which exhibit learning behavior. In designing a system, if the a priori infor mation required is unknown or incompletely known, one approach is to design a system which is capable of learning the unknown infor mation during its operation. The learned information will then be used to improve the system's performance. This approach has been used in the design of pattern recognition systems, automatic control systems and system identification algorithms. If we naturally extend our goal to the design of systems which will behave more and more intelligently, learning systems research is only a preliminary step towards a general concept of integrated intelligent systems. One example of this class of systems is the intelligent robot, which integrates pattern recognition. learning and problem-solving into one intelligent system.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 464 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -The science of photobiology is a dynamic multidisciplinary field whose relevance to the needs of man is growing more apparent each day. Publicity about supersonic transports (the SSTs) and spray cans, their possible dele terious effects on the stratospheric ozone layer, and the possible resultant consequences of enhanced solar ultraviolet radiation on man and his envi ronment have helped to focus attention on both the beneficial and the detri mental effects of light. In addition, considerable activity is currently being directed toward harnessing solar energy as one solution to the world energy crisis. Some mechanisms for accomplishing this involve photobiological systems or photochemical models based on these systems. It would thus seem that modern man has rediscovered the sun and is now actively considering new uses of light rather than thinking of light only as an aid to vision. Photobiology has become a major new scientific field. The American Society for Photobiology has divided the science of photobiology into 14 subspecialty groups: Phototechnology Chronobiology Photochemistry Photoreception Spectroscopy Vision Photosensitization Photomorphogenesis Ultraviolet and Visible Radiation Effects Photomovement Environmental Photobiology Photosynthesis Medicine Bioluminescence The goals of the science of photobiology have been divided into four categories\*: '(1) The development of ways to protect organisms, including man, from the detrimental effects of light; (2) the development of ways to control the beneficial effects of light upon our environment; (3) the con tinued development of photochemical tools for use in studies of life processes; and (4) the development of photochemical therapies inSpringer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 344 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -Considerable progress has been made in the past 20 years toward understanding the basic mechanisms of corrosion, and the application of this knowledge to its control. From the very beginning, educational institutions and industrial research laboratories have contributed greatly toward determining and elucidating the fundamental principles of corrosion reactions. Some of the basic principles involved in cor rosion of metals can be credited to early investigators. Michael Faraday in 1830-1840 studied the relationship between the quantity of a metal dissolved and the electric current which was produced by this reaction. He also proposed that the passivation of iron was through the formation of a film and that the dissolution of a metal was electro chemical in nature. Sir Humphrey Davy in 1824 worked out the funda mentals of galvanic corrosion of ships' hulls and applied sacrificial zinc anodes to protect them from sea water corrosion. Richard Arlie in 1847 demonstrated that corrosion produced by oxygen at the surface of iron in a flowing stream generated a current. With the fundamental knowledge available to him from these early investigators, Willis Rodney Whitney developed and expressed, in its most useful form, one of the basic scientific principles which provides modern corrosion specialists with a fundamental basis of corrosion control. Dr. Whitney concluded that corrosion of iron is electrochemical, and that the rate is simply a function of the electromotive force and resistance of the circuit.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 228 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -I have revised Moy-Thomas's widely used book on Palaeozoic fishes in an attempt to incorporate some of the considerable advances that have been made in this field over the last 30 years, which have in some respects made the first edition seriously out-of-date. The book is now inevitably longer, but its scope remains the same and the original approach has been main tained as far as possible. I have, however, undertaken a certain amount ofre arrangement of the contents, consonant with our changing views of fish evolution, and have tried to reflect some of the current preoccupations of students of fish evolution in expanded sections on mode of life and relation ships. The illustrations have been completely replaced, and in selecting the figures I have been faced with an embarrassing richness of source material. In an attempt to keep the figures down to a reasonable number, I have decided that it is better to have a few species illustrated with clear drawings than give thumb-nail sketches of all the forms mentioned in the text, and as far as possible to restrict the illustrations to Palaeozoic species. All the illustrations have been redrawn to a common style, and in some cases they have been specially prepared or modified for this book. Authors' names are now included in the text and a list of references is given at the end of each chapter.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 276 pp. Englisch.

Buch. Condición: Neu. Neuware -This volume is meant to provide the practitioner with information on the natural mixing processes occurring in aquifers as well as to describe basic strategies that can be implemented to enhance mixing in particular cases. For example, when it comes to mixing miscible liquids, one can speed up mixing in the formation by manipulating the flow such as through the use of recirculation wells. Furthermore, much of the mixing can be achieved partially within recirculation wells themselves, where contaminated water is admixed with additives, volatile products may be removed through a vapor mass exchanger, etc. Thus, adding mixing wells can significantly increase the performance of the delivery and mixing system and speed up the process of remediation.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 356 pp. Englisch.

Briefs allow authors to present their ideas and readers to absorb them with minimal time investment. As part of Springer¿s Elektronisches Buch collection, SpringBriefs are published to millions of users worldwide.Information/Data Leakage poses a serious threat to companies and organizations, as the number of leakage incidents and the cost they inflict continues to increase. Whether caused by malicious intent, or an inadvertent mistake, data loss can diminish a company¿s brand, reduce shareholder value, and damage the company¿s goodwill and reputation. This book aims to provide a structural and comprehensive overview of the practical solutions and current research in the DLP domain. This is the first comprehensive book that is dedicated entirely to the field of data leakage and covers all important challenges and techniques to mitigate them. Its informative, factual pages will provide researchers, students and practitioners in the industry with a comprehensive, yet concise and convenient reference source to this fascinating field.We have grouped existing solutions into different categories based on a described taxonomy. The presented taxonomy characterizes DLP solutions according to various aspects such as: leakage source, data state, leakage channel, deployment scheme, preventive/detective approaches, and the action upon leakage. In the commercial part we review solutions of the leading DLP market players based on professional research reports and material obtained from the websites of the vendors. In the academic part we cluster the academic work according to the nature of the leakage and protection into various categories. Finally, we describe main data leakage scenarios and present for eachscenario the most relevant and applicable solution or approach that will mitigate and reduce the likelihood and/or impact of the leakage scenario.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 100 pp. Englisch.

Buch. Condición: Neu. Neuware -Financial identity theft is well understood with clear underlying motives. Medical identity theft is new and presents a growing problem. The solutions to both problems however, are less clear.The Economics of Financial and Medical Identity Theft discusses how the digital networked environment is critically different from the world of paper, eyeballs and pens. Many of the effective identity protections are embedded behind the eyeballs, where the presumably passive observer is actually a fairly keen student of human behavior. The emergence of medical identity theft and the implications of medical data privacy are described in the second section of this book.The Economics of Financial and Medical Identity Theft also presents an overview of the current technology for identity management. The book closes with a series of vignettes in the last chapter, looking at the risks we may see in the future and how these risks can be mitigated or avoided.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 180 pp. Englisch.

Neuware -Presently, the need for methods involving separation, identification, and characterization of different kinds of cells is amply realized among immu nologists, hematologists, cell biologists, clinical pathologists, and cancer researchers. Unless cells exhibiting different functions and stages of differ entiation are separated from one another, it will be exceedingly difficult to study some of the molecular mechanisms involved in cell recognition, spe cialization, interactions, cytotoxicity, and transformation. Clinical diagno sis of diseased states and use of isolated cells for therapeutic (e. g. , immu notherapy) or survival (e. g, transfusion) purposes are some of the pressing areas where immediate practical benefits can be obtained by applying cell separation techniques. However, the development of such useful methods is still in its infancy. A number of good techniques exist based either on the physical or biological properties of the cells, and these have produced some valuable results. Still others are to be discovered. Therefore, the purpose of this open-ended treatise is to acquaint the reader with some of the basic principles, instrumentation, and procedures presently in practice at various laboratories around the world and to present some typical applications of each technique to particular biological problems.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 220 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -Most standard texts in basic organic chemistry require the student to memorize dozens of organic reactions. This is certainly necessary to master the discipline. Unfortunately, most texts do not emphasize why these reactions occur and, just as important, why other reactions that might seem conceivable to the student do not occur. Without this understanding, students tend to forget what they have memorized soon after the course is over. It is the purpose of this book to familiarize the student with the principles governing organic reactivity and to provide a 'feel' for organic chemistry that is impossible to secure by memory alone. Digesting the ideas in this book will, we hope, not only explain the common organic reactions but also allow the student to predict the prod ucts and by-products of reactions he has never seen before. Indeed, the creative student might even become capable of designing new reactions as might be required in a complex organic synthesis. In Chapter 1, we cover the basic principles including bonding, nuclear charge, resonance effects, oxidation-reduction, etc. It is a brief discussion, but it nonetheless provides the basis for understanding reaction mechanisms th~t will be treated later on. We highly recommend that this material be reviewed and that the v VI PREFACE problems be worked at the end of the chapter. Answers are given to all problems. In Chapter 2, reaction mechanisms are presented in an increas ing order of difficulty.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 228 pp. Englisch.

Wellington chicago, IL 60657 Although introduction of a first trimester prenatal diagnosis by chorionic viIIus sampling (CVS) has considerably improved the possibility for prevention of genetic diseases, it requires a selective abortion in case of an affected fetus. Following the direction of an earlier prenatal diagnosis and to avoid the need for abortion, preimplantation genetic diagnosis has been initiated based on polar body removal and pre-embryo biopsy. The First International symposium on Preimplantation Genetics, Chicago, September 17-19, 1990, was organized to explore these important developments, to review the state of knowledge in the field, and to address existing problems to be solved for developing and improving current approaches for preimplantation diagnosis of genetic disorders. A growing interest in the subject was obvious from the wide attendance of the meeting: over 250 scientists from 19 countries participated. This was the first attempt to put together the advances in different areas of basic and applied research relevant to Preimplantation Genetic Diagnosis, with the multidisciplinary scientific program including the sessions on embryology, micromanipulation and biopsy, genetic analysis of gametes and pre-embryos, IVF, gene expression and gene therapy, and ethical and legal issues. The deliberations of the Symposium presented in the above mentioned sessions, which comprise the contents of correspond ing sections of the Proceedings, open a newarea in medical research based on the interaction of IVF and New Genetics.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 340 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -It took us a long time to write this book. In 1959, two of us (Lifshits and Kaganov) pub lished a review of the mechanics of electrons with a complex dispersion law. About that time, geometrical terms such as extremal sections, curvatures, diameters, limiting points began to appear in papers on the electron theory of metals. They were followed by terms quite unusual in the scientific literature: monsters, pockets, arms, sheets, and so on. With their excitingly shaped figures, papers on the electron theory of metals began to resemble catalogs of exhibitions of abstract or ultramodern sculpture. The modern theory of metals was passing through its romantic period. Each newly interpreted Fermi surface and each discovery of a new structure sensitive phenomenon was an emotional experience for the authors and readers alike. The atti tude of the theoreticians was epitomized by phrases such as 'This method or this phenomenon can be used to reconstruct the Fermi surface . . . ,' which were found at the end of almost every paper on the electron theory of metals. The experimentalists selected convenient meth ods, being guided not so much by the elegance of a particular method as by its experimental capabilities. Gradually, the romantic approach gave way to a systematic activity, which re sulted in the interpretation of the energy spectra of the majority of metals. There were some unavoidable disappointments.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 340 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -This volume of Astrophysical Data deals with Planets and Stars; a second volume, Part II, will give data for Galaxies and the Universe. They both pro vide basic data for use by all scientists, from the amateur astronomer to the professional astrophysicist. In this first volume, we not only provide physical parameters of planets, stars and their environment, but we also provide the celestial coordinates required to observe them. Here we use c.g.s. units, for they are the most commonly used in astron omy and astrophysics; but our volume begins with astronomical and physical constants and the conversion factors needed for other units. The next section concerns the planets and their satellites; it singles out the Earth and Moon for special treatment. Spacecraft rendezvous with the planets and satellites have led to improved values for their atmospheric compositions, orbital parameters, magnetic fields, masses, radii, rotation periods, and surface pressures and temperatures. This section also contains data for the asteroids, comets and their debris. We then discuss everyday stars, beginning with the Sun, and continuing with basic stellar data, the brightest stars and nearby stars. Special categories of stars, such as the Wolf-Rayet stars, magnetic stars, flare stars, and RS CVn binary stars, are included.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 960 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -The study of formal languages and of related families of automata has long been at the core of theoretical computer science. Until recently, the main reasons for this centrality were connected with the specification and analy sis of programming languages, which led naturally to the following ques tions. How might a grammar be written for such a language How could we check whether a text were or were not a well-formed program generated by that grammar How could we parse a program to provide the structural analysis needed by a compiler How could we check for ambiguity to en sure that a program has a unique analysis to be passed to the computer This focus on programming languages has now been broadened by the in creasing concern of computer scientists with designing interfaces which allow humans to communicate with computers in a natural language, at least concerning problems in some well-delimited domain of discourse. The necessary work in computational linguistics draws on studies both within linguistics (the analysis of human languages) and within artificial intelligence. The present volume is the first textbook to combine the topics of formal language theory traditionally taught in the context of program ming languages with an introduction to issues in computational linguistics. It is one of a series, The AKM Series in Theoretical Computer Science, designed to make key mathematical developments in computer science readily accessible to undergraduate and beginning graduate students.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 216 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -The First European Symposium on Calcium-Binding Proteins in Normal and Transformed Cells was held at the Faculty of Medicine of the 'Universit6 Libre de Bruxelles' in Brussels, Belgium, April 20-22, 1989. Delegates from seventeen countries attended. This Symposium was initiated through an EEC Stimulation Program. The formal program included forty verbal presentations by invited speakers and sixty miniposter presentations, and was formulated by the Organizing and Scientific Committee: E. Carmeliet (Leuven), J. P. Collin (Poitiers), S. Forsen (Lund), C. W. Heizmann (Ziirich), D. E. M. Lawson (Cambridge), P. Miroir (Brussels), J. L. Pasteels (Brussels) and R. Pochet (Brussels). This volume contains the papers prepared by the invited speakers. The contributions are grouped according to their general subject matter: Genes of Calcium-Binding Protein Family, Structure/Function Relationships, The Cytoskeleton and Calcium-Binding Proteins, Calcium-Binding Proteins in TransforlIled Cells, Calcium/Lipid-Binding Proteins, Calcium-Binding Proteins Substrates and Immunohistochemistry of Calbindin and Calretinin. The highlights of the symposium are numerous. Among the items to be noted are the growing number of abundant proteins which interact with calcium and sometimes with other second messenger sys tems; specifically pH associated with the tyrosine kinase calpactin, calcYclin, p9Ka induced by growth fac tors, MRP-8 and MRP-14 (also called cystic fibrosis antigen, L1 or calgranulins) forming half the soluble protein of granulocytes. New structure/function relationships on calbindin D9K and calmodulin have emerged from nuclear magnetic resonance and site-directed mutagenesis studies.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 228 pp. Englisch.
