Taschenbuch. Condición: Neu. Neuware -Field-programmable logic has been available for a number of years. The role of Field-Programmable Logic Devices (FPLDs) has evolved from simply implementing the system `glue-logic' to the ability to implement very complex system functions, such as microprocessors and microcomputers. The speed with which these devices can be programmed makes them ideal for prototyping. Low production cost makes them competitive for small to medium volume productions. These devices make possible new sophisticated applications, and bring up new hardware/software trade-offs and diminish the traditional hardware/software demarcation line. Advanced design tools are being developed for automatic compilation of complex designs and routings to custom circuits. Digital Systems Design and Prototyping Using Field Programmable Logic covers the subjects of digital systems design and (FPLDs), combining them into an entity useful for designers in the areas of digital systems and rapid system prototyping. It is also useful for the growing community of engineers and researchers dealing with the exciting field of FPLDs, reconfigurable and programmable logic. The authors' goal is to bring these topics to students studying digital system design, computer design, and related subjects in order to show them how very complex circuits can be implemented at the desk. Digital Systems Design and Prototyping Using Field Programmable Logic makes a pioneering effort to present rapid prototyping and generation of computer systems using FPLDs. From the Foreword: `This is a ground-breaking book that bridges the gap between digital design theory and practice. It provides a unifying terminology for describing FPLD technology. In addition to introducing the technology it also describes the design methodology and tools required to harness this technology. It introduces two hardware description languages (e.g. AHDL and VHDL). Design is best learned by practice and the book supports this notion with abundant case studies.' Daniel P. Siewiorek, Carnegie Mellon University CD-ROM INCLUDED!

Taschenbuch. Condición: Neu. Neuware -¿Weird Worlds¿ is the third book in David Seargent¿s ¿Weird¿ series. This book assumes a basic level of astronomical understanding and concentrates on the ¿odd and interesting¿ aspects of planetary bodies, including asteroids and moons. From our viewpoint here on Earth, this work features the most unusual features of these worlds and the ways in which they appear ¿weird¿ to us. Within our own Solar System, odd facts such as the apparent reversal of the Sun in the skies of Mercury, CO2-driven fountains of dust on Mars, possible liquid water (and perhaps primitive life!) deep within the dwarf planet Ceres, and a variety of odd facts about the planetary moons are all discussed. A special chapter is devoted to Saturn¿s giant moon Titan, and its methane-based weather system and ¿hydrological¿ cycle. This chapter also includes recent speculation on the possibility of methane-based organisms and the form that these might take, if they really do exist. Beyond our Solar System, the book looks at the range of worlds discovered and hypothesized.In ¿Weird Worlds,¿ the author discusses planets where temperatures are so high that it rains molten iron, and others so cold that liquid methane floods across plains of ice! Worlds are described where the lightest element acts like a metal and where winds blow at thousands of miles per hour ¿ as well as possible planets whose orbits are essentially parabolic.In keeping with previous titles in David Seargent¿s ¿Weird¿ series, ¿Weird Worlds¿ contains several projects that astronomers of all levels can undertake.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 324 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -This text is an introduction to the modern theory and applications of probability and stochastics. The style and coverage is geared towards the theory of stochastic processes, but with some attention to the applications. In many instances the gist of the problem is introduced in practical, everyday language and then is made precise in mathematical form.The first four chapters are on probability theory: measure and integration, probability spaces, conditional expectations, and the classical limit theorems. There follows chapters on martingales, Poisson random measures, Levy Processes, Brownian motion, and Markov Processes.Special attention is paid to Poisson random measures and their roles in regulating the excursions of Brownian motion and the jumps of Levy and Markov processes. Each chapter has a large number of varied examples and exercises.The bookis based on the author¿s lecture notes in courses offered over the years at Princeton University. These courses attracted graduate students from engineering, economics, physics, computer sciences, and mathematics.Erhan Cinlar has received many awards for excellence in teaching, including the President¿s Award for Distinguished Teaching at Princeton University. His research interests include theories of Markov processes, point processes, stochastic calculus, and stochastic flows. The book is full of insights and observations that only a lifetime researcher in probability can have, all told in a lucid yet precise style.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 572 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -Because statistical confidentiality embraces the responsibility for both protecting data and ensuring its beneficial use for statistical purposes, those working with personal and proprietary data can benefit from the principles and practices this book presents. Researchers can understand why an agency holding statistical data does not respond well to the demand, 'Just give me the data; I'm only going to do good things with it.' Statisticians can incorporate the requirements of statistical confidentiality into their methodologies for data collection and analysis. Data stewards, caught between those eager for data and those who worry about confidentiality, can use the tools of statistical confidentiality toward satisfying both groups.The eight chapters lay out the dilemma of data stewardship organizations (such as statistical agencies) in resolving the tension between protecting data from snoopers while providing data to legitimate users, explain disclosure risk and explore the types of attack that a data snooper might mount, present the methods of disclosure risk assessment, give techniques for statistical disclosure limitation of both tabular data and microdata, identify measures of the impact of disclosure limitation on data utility, provide restricted access methods as administrative procedures for disclosure control, and finally explore the future of statistical confidentiality.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 212 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -The first edition of this book was based on the lectures which I gave at Cornell University during 1958 as George Fisher Baker Lecturer, and I would like to repeat my warmest thanks to Professor F. A. Long and the other members of the Department of Chemistry for their kindness and helpful advice. The present edition was largely written during the tenure of a Visiting Professorship awarded by the Royal Society and the Israeli Academy of Sciences. I am deeply indebted to both of these bodies and also to the hospitality of the Weizmann Institute of Science, in particular to Professor David Samuel and Professor F. S. Klein of the Isotopes Research Department. The subject as a whole has expanded greatly since 1959, especially in two fields, namely, the direct study of fast proton-transfer reactions (notably by the relaxation methods pioneered by Eigen), and the experi mental and theoretical study of hydrogen isotope effects. In order to keep the size of the book within reasonable bounds it has been necessary to adopt a selective policy, and this is particularly the case in Chapter 9 where I have chosen to treat a few types of reaction in some detail rather than to attempt a more complete coverage.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 320 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -This book is meant for laboratory workers who for one reason or another have a need to cool something down to temperatures below that of liquid nitrogen - notably to 4. 2°K and below. It does not deal with experimental techniques at low temperatures, but I have tried to bring the reader face to face with the brutishrealities of the necessary hardware. As weIl as giving information about sources of supply of equipment, I have gone into so me detail about how some of it can be made in laboratory workshops for the sake of those who are short of money but blessed with competent technical support. So far as highly specialized items such as liquefiers, refrigerators, refrigerant containers, cryostat dewars, etc. , are concerned, I have included aIl sources of supply which I have got to he ar of; in the case of more generaIly available equipment only representative sources of known reliability have been quoted. Any omissions or errors must be put down either to my own ignorance, stupidity, or lack of will toget about the world, or perhaps to the difficulty I have had in extracting information from manufacturers. However, most have gone to great trouble to help, and I hope I have done them justice. Brought up to work indifferently in inches and centimetres and perched between the opposing puIls of the USA and Europe, I have used a mixture of units which may shock the purist.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 196 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -Profound changes were taking place in American society during the period of the 1960s and 1970s when legislation for the National Foundation for the Arts and the Humanities was enacted and the agencies went into operation. It was a period of soul-searching by the American public when the cherished prejudices and civil inequities of the past decades were wiped out and old wounds began to heal; at the same time, however, the Vietnam War was creating new fissures and antagonisms. Into this newly healing, newly questioning society, congressional action thrust the National Council on the Arts in 1964, and the National Endowment for the Arts in 1965. Their mission was to encourage and support the arts, and the men and women charged with this responsibility went about their work with the zeal and enthusiasm of religious converts. The idea of even a minute amount of federal financial assistance to the country's chronically beleaguered and often impoverished artists and arts organi zations seemed strange to a segment of the population that had existed in forgot ten independence from government intervention. Many of the nation's artists and arts leaders were wary, partly because of the uncertainties and constraints of previous patterns of governmental support.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 292 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -By introducing Semantic Web technologies into geospatial Web services, this book addresses the semantic description of geospatial data and standards-based Web services, discovery of geospatial data and services, and generation of composite services. Semantic descriptions for geospatial data, services, and geoprocessing service chains are structured, organized, and registered in geospatial catalogue services. The ontology-based approach helps to improve the recall and precision of data and services discovery. Semantics-enabled metadata tracking and satisfaction allows analysts to focus on the generation of a geospatial process model rather than spending large amounts of time in data preparation. ¿DataType¿-driven service composition and path planning can help to automate a range of knowledge discovery processes in a limited geospatial domain. Process planning facilitates the construction of complex services and models for geocomputation. A three-phase procedure to cover the lifecycle of service chaining and to identify the roles of the methods involved is proposed. It includes process modeling, process model instantiation, and workflow execution. The approach is implemented in a prototype system with use cases to demonstrate applicability. The objective of the research is to develop the key technologies for an intelligent geospatial knowledge system based on Web services to automate the data discovery and data preprocessing steps in the distributed Web service environment, to automate a range of knowledge discovery processes in a limited geospatial domain, using the automated construction and execution of service chains, and to facilitate the construction of complex services and models for geocomputation.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 120 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -This SpringerBrief is comprehensive account of the functions and effects of the Epstein-Barr virus (EBV) EBNA1 protein that relate to EBV-associated cancers and evidence for EBNA1 contributions to these cancers. EBNA1 was the first EBV protein detected and the most critical for EBV latent infection. EBNA1 fulfills multiple functions at EBV genomes which have been described in many (sometimes confusing) reports over the last 28 years. While these were initially thought to be the only roles of EBNA1, many reports in recent years have shown that EBNA1 also directly affects cellular processes in ways that would be expected to contribute to oncogenesis. However, the degree to which EBNA1 promotes cell survival and oncogenesis in various types of human tumours is not entirely clear and a matter of debate. Thisbook offersa currentsynopsis of EBNA1 functions in EBV latency, including functions in DNA replication, mitotic segregation and transcription. Mechanisms of these EBNA1 functions is also discussed as well as implications for tumourigenesis. In addition, the cellular effects of EBNA1 will be reviewed, including how EBNA1 manipulates specific cellular proteins and relationships to EBV-associated lymphomas and carcinomas.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 52 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -Welcome to the world of Verilog! Once you read this book, you will join the ranks of the many successful engineers who use Verilog. I have been using Verilog since 1986 and teaching Verilog since 1987. I have seen many different Verilog courses and many approaches to learning Verilog. This book generally follows the outline of the Verilog class that I teach at the University of California, Santa Cruz, Extension. This book does not take a 'cookie-cutter' approach to learning Verilog, nor is it a completely theoretical book. Instead, what we will do is go through some of the formal Verilog syntax and definitions, and then show practical uses. Once we cover most of the constructs of the language, we will look at how style affects the constructs you choose while modeling your design. This is not a complete and exhaustive reference on Verilog. If you want a Verilog reference, I suggest one of the Open Verilog International (OVI) reference manuals.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 332 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -It is now more than 100 years since certain detrimental effects on the ductility of iron were first associated with the presence of hydrogen. Not only is hydrogen embrittlement still a major industri al problem, but it is safe to say that in a mechanistic sense we still do not know what hydrogen (but not nitrogen or oxygen, for example) does on an atomic scale to induce this degradation. The same applies to other examples of environmentally-induced fracture: what is it about the ubiquitous chloride ion that induces premature catastrophic fracture (stress corrosion cracking) of ordinarily ductile austenitic stainless steels Why, moreover, are halide ions troublesome but the nitrate or sulfate anions not deleterious to such stainless steels Likewise, why are some solid metals embrit tled catastrophically by same liquid metals (liquid metal embrit tlement) - copper and aluminum, for example, are embrittled by liquid mercury. In short, despite all that we may know about the materials science and mechanics of fracture on a macroscopic scale, we know little about the atomistics of fracture in the absence of environmental interactions and even less when embrittlement phe nomena such as those described above are involved. On the other hand, it is interesting to note that physical chemists and surface chemists also have interests in the same kinds of interactions that occur on an atomic scale when metals such as nickel or platinum are used, for example, as catalysts for chemical reactions.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 1096 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -In 1978, when the book Living Systems was published, it contained the prediction that the sciences that were concerned with the biological and social sciences would, in the future, be stated as rigorously as the ¿hard sciences¿ that study such nonliving phenomena as temperature, distance, and the interaction of chemical elements. Principles of Quantitative Living Systems Science, the first of a planned series of three books, begins an attempt to fulfill that prediction. The view that living things are similar to other parts of the physical world, differing only in their complexity, was explicitly stated in the early years of the twentieth century by the biologist Ludwig von Bertalanffy. His ideas could not be published until the end of the war in Europe in the 1940s. Von Bertalanffy was strongly opposed to vitalism, the theory current among biologists at the time that life could only be explained by recourse to a ¿vital principle¿ or God. He c- sidered living things to be a part of the natural order, ¿systems¿ like atoms and molecules and planetary systems. Systems were described as being made up of a number of interrelated and interdependent parts, but because of the interrelations, the total system became more than the sum of those parts. These ideas led to the development of systems movements, in both Europe and the United States, that included not only biologists but scientists in other fields as well. Systems societies were formed on both continents.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 300 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -The theme of this volume--risk analysis in the private sector--reflects a changing emphasis in risk analysis. Until re cently, attention has been focused on risk analyses conducted in support of federal regulatory decision making. Such analyses have been used to help set safety standards, to illuminate issues of regulatory concern, and to evaluate regulatory alternatives. As this volume indicates, however, risk analysis encompasses a broader set of activities. Analyses performed by private sector institutions aimed at preventing or reducing potential adverse health or environmental effects also play an important part in societal risk management. In virtually all societies, there have been strong incentives for the private sector to conduct such analyses. These incentives range from moral or altruistic norms and values to simple self-interest based on fear of monetary loss, possible civil or criminal litigation, or punitive or restrictive government action. The papers in this volume address the overall theme from a variety of perspectives. Specifically, the papers represent con tributions from such diverse fields as toxicology, epidemiology, chemistry, biology, engineering, statistics, decision analysis, economics, psychology, philosophy, and the law.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 520 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -The oceans are shrinking. They're not literally shrinking; warming in the last century has actually expanded the sea enough to threaten low-lying coastal lands that are vul nerable to storm surge. During the same interval, however, events on land have increasingly affected the sea. Since in most ways the Earth is a closed system-a zero-sum planet in today's parlance-as terrestrial influence on the sea expands, the sea's influence on its own processes shrinks. Control of many crucial marine processes no longer resides within the sea. The evidence for this is abundant and, to anyone who is looking, unmis takable. In recent decades scientists have witnessed unprecedented pertur bations and increases in previously uncommon events that demonstrate growing terrestrial influences on the sea. Numerous marine species, from sea urchins to monk seals, have experienced devastating epidemics. The number of harmful algal blooms and jellyfishpopulation explosions is rising An hypoxic 'dead zone' in the Gulf of Mexico off the mouth of the Mississippi Rivernow appears each year and grows to encompass an area as large as NewJersey. Live coral cover in shallow reefs in Florida,Jamaica, the Maldives and many other locations has severely declined. Deepwater reef building corals, once widely distributed, have disappeared throughout much of their ranges. Researchers have discovered high concentrations of persis tent organic pollutants in declining populations of beluga whales and polar bears, both high trophic level predators in marine food webs.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 476 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -This volume is based on the proceedings of a NATO-Gulbenkian Foundation sponsored Summer School held in May-June 1982 in Sintra Estoril, Portugal. Given the accelerated growth of knowledge in the field of eukaryotic gene expression, it seemed timely to hold a NATO Advanced Study Institute to discuss current developments in this area of biology and to evaluate the potential of emerging technologies such as gene transfer, recombinant DNA cloning and quantitative high resolution two-dimensional gel electrophoresis. The initial articles in t~is volume describe various differentiation models and address questions such as the relationships between differentiation and cell proliferation, biochemical changes accompanying differen tiation, expression of differentiated gene products and their regulation as well as gene organization of cytoskeletal proteins. The second section describes properties of neoplastic cells, surveys current assays for transformation and offers some new insights into the mechanisms involved in carcinogenesis. The third part is dedicated to viral oncogenesis and to the role of onco genes in cell transformation. Particular emphasis is given to the role of tyrosine kinases in cell transformation. The concluding section deals with various aspects of gene expression in normal and transformed cells with special emphasis given to studies using two dimensional gel electrophoresis, cell hybridization, gene transfer and immunological techniques.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 456 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -Sphere Packings is one of the most attractive and challenging subjects in mathematics. Almost 4 centuries ago, Kepler studied the densities of sphere packings and made his famous conjecture. In the course of centuries, many exciting results have been obtained, ingenious methods created, related challenging problems proposed, and many surprising connections with othe subjects found. Thus, though some of its original problems are still open, sphere packings has been developed into an important discipline. This book tries to give a full account of this fascinating subject, especially its local aspects, discrete aspects and its proof methods.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 260 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -The world consists of many complex systems, ranging from our own bodies to ecosystems to economic systems. Despite their diversity, complex systems have many structural and functional features in common that can be effectively si- lated using powerful, user-friendly software. As a result, virtually anyone can - plore the nature of complex systems and their dynamical behavior under a range of assumptions and conditions. This ability to model dynamic systems is already having a powerful influence on teaching and studying complexity. The books in this series will promote this revolution in ¿systems thinking¿ by integrating computational skills of numeracy and techniques of dynamic mod- ing into a variety of disciplines. The unifying theme across the series will be the power and simplicity of the model-building process, and all books are designed to engage the reader in developing their own models for exploration of the dyn- ics of systems that are of interest to them. Modeling Dynamic Systems does not endorse any particular modeling paradigm or software. Rather, the volumes in the series will emphasize simplicity of lea- ing, expressive power, and the speed of execution as priorities that will facilitate deeper system understanding.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 348 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -Hepatitis A virus (HAV) is responsible for around half of the total number of hepatitis infections diagnosed worldwide. HAV infection is mainly propagated via the fecal-oral route, and as a consequence of globalization, transnational outbreaks of foodborne infections are reported with increasing frequency. Therefore, in this review, state-of-the-art information on the molecular procedures for HAV detection in food, and the efficacy of common food manufacturing processes are compiled. The purpose of this Brief is to consolidate basic information on various aspects of HAV and to provide a guideline for its prevention and control across the food supply chain from pre-harvest to manufacturing. ¿Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 60 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -The Advanced Study Institute on Breakdown and Discharges in Gases was held in Les Arcs, France, June 28 to July 10, 1981. The object of the Institute was to provide a broad but compre hensive presentation of the various topics in the field of Gaseous electronics. To achieve this goal, a number of lectures, seminars, and panel discussions were scheduled. Each topic was developed by two tutorial and/or review lectures, and brought to the present state of the topic by seminars and panel discussions. The program of topics and speakers was selected with the assistance of the advisory committee composed of: J. A. Rees, European Coordinator, England; M. Goldman, French Coordinator, France; A. H. Guenther, USA; M. Kristiansen, USA; and A. V. Phelps, USA. The most memorable aspect of the Institute was the sustained high interest of the faculty and participants for the two week period. The daily schedule was demanding: five hours of lectures, two hours of seminars and one of discussion. These sessions were often extended because of presentation by the participants of im proptu seminars. The discussions were intense. Majestic }10nt Blanc provided the backdrop for the lecture hall, and these surroundings and the weather contributed to the overall positive mood. It was a wonderful occasion. The lectures and seminars have been collected into two volumes.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 480 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -The need for long-term energy sources, in particular for our highly technological society, has become increasingly apparent during the last decade. One of these sources, of tremendous poten tial importance, is controlled thermonuclear fusion. The goal of controlled thermonuclear fusion research is to produce a high-temperature, completely ionized plasma in which the nuclei of two hydrogen isotopes, deuterium and tritium, undergo enough fusion reactions so that the nuclear energy released by these fusion reactions can be transformed into heat and electricity with an overall gain in energy. This requires average kinetic energies for the nuclei of the order of 10 keV, corresponding to temperatures of about 100 million degrees. Moreover, the plasma must remain confined for a certain time interval, during which sufficient energy must be produced to heat the plasma, overcome the energy losses and supply heat to the power station. At present, two main approaches are being investigated to achieve these objectives: magnetic confinement and inertial con finement. In magnetic confinement research, a low-density plasma is heated by electric currents, assisted by additional heating methods such as radio-frequency heating or neutral beam injection, and the confinement is achieved by using various magnetic field configurations. Examples of these are the plasmas produced in stellarator and tokamak devices.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 592 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -was the result of the efforts of Robert Cleverdon. The rapidly developing discipline of molecular biology and the rapidly expanding knowledge of the PPLO were brought together at this meeting. In addition to the PPLO specialists, the conference invited Julius Marmur to compare PPLO DNA to DNA of other organisms; David Garfinkel, who was one of the first to develop computer models of metabolism; Cyrus Levinthal to talk about coding; and Henry Quastler to discuss information theory constraints on very small cells. The conference was an announcement of the role of PPLO in the fundamental understanding of molecular biology. Looking back 40-some years to the Connecticut meeting, it was a rather bold enterprise. The meeting was international and inter-disciplinary and began a series of important collaborations with influences resonating down to the present. If I may be allowed a personal remark, it was where I first met Shmuel Razin, who has been a leading figure in the emerging mycoplasma research and a good friend. This present volume is in some ways the fulfillment of the promise of that early meeting. It is an example of the collaborative work of scientists in building an understanding of fundamental aspects of biology.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 592 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -The approach to teaching the concepts offood processing to the undergrad uate food science major has evolved over the past 40 years. In most under graduate food science curricula, food processing has been taught on a commodity basis. In many programs, several courses dealt with processing with emphasis on a different commodity, such as fruits and vegetables, dairy products, meat products, and eggs. In most situations, the emphasis was on the unique characteristics of the commodity and very little empha sis on the common elements associated with processing of the different commodities. Quite often the undergraduate student was allowed to select one or two courses from those offered in order to satisfy the minimum standards suggested by the Institute of Food Technologists. The current 1FT minimum standards suggest that the undergradu ate food science major be required to complete at least one food processing course. The description of this course is as follows: One course with lecture and laboratory which covers general characteristics of raw food materials, principles offood preserva tion, processing factors that influence quality, packaging, water and waste management, and sanitation. Prerequisites: general chemistry, physics, and general microbiology.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 308 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -The study ofanthropoid origins continues to be a lightning rod for research in paleoanthropology. Issuessurrounding anthropoid origins impact the higher leveltaxonomy ofprimates, adaptivescenariosfor basalprimate radiations, and the timing of origination of the major primate clades. Basic questions about anthropoid evolution remain unanswered. Where do anthropoids fit phyloge netically among primates Where and when did the group originate What functional and adaptive innovations characterize anthropoids today and what is the adaptive significanceand phylogenetic history ofthese innovations The fossil record of early anthropoid evolution has greatly improved in recent years. Developments in systematictechniques and theory, as well as the burgeoning molecular evidence, make this an ideal time for these fossil discoveries to be placed in the context of data on the relationships among living primates. There isan improved understandingoffunction and adaptation in the visual system, brain, and masticatory apparatus, key anatomical systems where anthropoid synapomorphies are concentrated. New methods for estimating visualacuity and activitypatterns in fossil primates are providing insights into the evolution ofthe visualsystem. The rapid accumulation ofinformation on color vision in primates, including new genetic evidence of possible trichro macyin strepsirrhines, and new behavioraldata on the benefitsofcolor vision, makes this an exciting time to evaluate the role of chromatic perception in anthropoid evolution. Research into the primate visualsystem by neuroscien tists has generated a plethoraofimportant data in recent years, making this an ideal time to bring these researchers together with anthropologists.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 796 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -The search for flavored particles is one of the most;interesting topics in high energy physics. Many experimental groups are working on this subject, but the solution to many of the problems are still open. Therefore it seemed very useful that people interested in these problems can probe then in a discussion. This is the aim of this Europhysics Study Conference, which has been organized both as a conference and a workshop. The present experimental knowledge on branching ratios, life times, cross sections and production mechanisms of flavored parti cles has been presented in general talks and discussed in the morn ing sessions, as well as the bases of the theoretical ideas and pre dictions. The experimental methods: visual detectors, live targets, high resolution vertex detectors, special triggers of search on fla vored particles, have been treated in the afternoon panels. These proceedings contain the talks and panel discussions with the exception of a few small contributions to the panels and talks by C. Baltay ('Search for charm and new flavors with bubble cham bers'), G. Alteralle ('Lifetime of charm and new flavors'), P. Monacelli ('Results on charm production from a CERN Beam Dump exper iment'), A. Capone ('Experimental study of same-sign dimunon events produced in neutrino and anti-neutrino beams').Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 600 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -The Advanced Study Institute on 'Advances in Superconductivity' was held at the Ettore Majorana Centre for Scientific Culture in Erice, Sicily, during July 3 to July 15, 1982. This Institute was the third course of the International School of Low Tempera ture Physics, which was established at the Centre in 1977 with the guidance and inspiration of T. Regge and A. Zichichi. The 1982 Course was centered on a topic which brought together fundamental basic research and the most recent promising technological applications. Accordingly, the participants represented a wide spectrum of industrial and government laboratories, as well as universities from various countries. The program of topics and speakers was developed with the advice of the Organizing Committee, composed of H. Frohlich, T. Regge, B. Stritzker, and L. Testardi. This Institute emphasized recent developments in the science and technology of superconductivity. A historical perspective was provided by H. Frohlich, whose lectures recall the earliest discoveries and theoretical attempts to understand superconductivity. Ironically, his early suggestion of the electron-phonon coupling as a key to superconductivity was met with initial widespread skepticism. Later, the development of field theory methods for solid state physics problems, and the evolution of the BCS theory has led to a seemingly unanimous concensus regarding the e1ectron phonon mechanism as the predominant source of superconductivity in known materials. Experimental studies of superconductivity exemplify the strong interplay of science and technology in many ways.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 540 pp. Englisch.
