Taschenbuch. Condizione: Neu. Neuware -This book shows amateur astronomers how to use one-shot CCD cameras, and how to get the best out of equipment that exposes all three color images at once. Because this book is specifically devoted to one-shot imaging, 'One-Shot Color Astronomical Imaging' begins by looking at all the basics - what equipment will be needed, how color imaging is done, and most importantly, what specific steps need to be followed after the one-shot color images are taken.What is one-shot color imaging Typically, astronomical cooled-chip CCD cameras record only one color at a time - rather like old-fashioned black & white cameras fitted with color filters. Three images are taken in sequence - in red, blue, and green light - and these are then merged by software in a PC to form a color image. Each of the three images must be taken separately through a suitable color filter, which means that the total exposure time for every object is more than tripled. When exposure times can run into tens of minutes or even hours for each of the three colors, this can be a major drawback for the time-pressed amateur.'One-Shot Color Astronomical Imaging' describes the most cost-effective and time-efficient way for any amateur astronomer to begin to photograph the deep-sky.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 212 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The Andromeda Galaxy ¿ Messier¿s M31 ¿ has an almost romantic appeal. It is the most distant object and the only extragalactic object that is visible to the unaided human eye. Now known to be about 2¿ million light-years away, it appears in the sky to be several times the width of the full Moon under good seeing conditions. The Andromeda Galaxy and the Rise of Modern Astronomy examines the astronomical studies of Andromeda and its importance to our developing knowledge of the universe. The book discusses how M31 was described both by the Ancients, but more importantly, by astronomers from the nineteenth century to the present.While at the start of the twentieth century the universe was thought of as a finite cosmos dominated by the Milky Way, the study of Andromeda galaxy shattered that image, leading ultimately to the conception of an infinite universe of countless galaxies and vast distances. Even today, M31 is a major focal point for new astronomical discoveries, and it also remains one of the most popular (and rewarding) celestial objects for amateur astronomers to observe and study. This book reveals the little-known history of M31 and the scientists who study it.For all who are interested in astronomy, the skies, and perhaps even the origins of the universe, The Andromeda Galaxy and the Rise of Modern Astronomy provides a first-of-its-kind accessible, informative, and highly readable account of how the study and observation of this celestial object has driven the development of astronomy from ancient times to the present.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 284 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Over the last 50 years there have been an increasing number of applications of algebraic tools to solve problems in communications, in particular in the fields of error-control codes and cryptography. More recently, broader applications have emerged, requiring quite sophisticated algebra - for example, the Alamouti scheme in MIMO communications is just Hamilton's quaternions in disguise and has spawned the use of PhD-level algebra to produce generalizations. Likewise, in the absence of credible alternatives, the industry has in many cases been forced to adopt elliptic curve cryptography. In addition, algebra has been successfully applied to problems in signal processing such as face recognition, biometrics, control design, and signal design for radar. This book introduces the reader to the algebra they need to appreciate these developments and to various problems solved by these techniques.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 60 pp. Englisch.

Neuware -This year, Orbis Scientiae 1976, dedicated to the Bicentennial of the United States of America, was devoted entirely to recent developments in high energy These proceedings contain nearly all of the physics. papers presented at Orbis, held at the Center for Theoretical Studies, University of Miami, during January 19-22, 1976. The organization of Orbis this year was due mainly to the moderators of the sessions, principally Sydney Meshkov, Murray Gell-Mann, Yoichiro Nambu, Glennys Farrar, Fred Zachariasen and Behram Kursunoglu, who was also chairman of the conference. The coherence of the various sessions is due to their efforts, and special thanks are due to Sydney Meshkov who was responsible for coor dinating many.of the efforts of the moderators and for including essentially all of the frontier developments in high energy physics. Because of the number of papers and their integrated length, it has been necessary to divide these proceedings into two volumes. An effort has been made to divide the material in the two volumes into fundamental questions (including the appearance of magnetic charge in particle physics) and recent high energy results and attendant phenomenology. These volumes were prepared by Mrs. Helga Billings, Mrs. Elva Brady and Ms. Yvonne Leber, and their dedication and skill are gratefully acknowledged. Their efforts v PREFACE during Orbis were supplemented by those of Mrs. Jacquelyn Zagursky, with our appreciation. The ~hoto graphs were taken by Ms. Shirley Busch.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 420 pp. Englisch.

Buch. Condizione: Neu. Neuware -¿Health care is a very important component of the American economy. The United States Centers for Medicare and Medicaid Services (CMS) put the 2008 direct health care expenditures at about $2.34 trillion, or about 16.2 percent of the nation¿s gross domestic product (GDP), or an average of $7,681 spent for every man, woman, and child in the country. Health care cost increases have caused very serious problems that threaten to bankrupt the system, providers, employers, and the families that pay the costs that their health insurance plans do not cover. Additionally, cost increases have reduced access to health care services, adversely affected the quality of care, and resulted in avoidable illnesses, premature deaths, and in health disparities based on race, ethnicity, and income.Consequently, health care reform has continuously been on the public and governmental agendas. It is out of this environment that several reform plans, including the 1993 Health Security Act, and the 2010 Patient Protection and Affordable Care Act (PPACA), were launched. This book examines the ideological, social, cultural, economic, and several other factors that dictate the various measures and approaches employed to tackle the perceived problems. The book has an index, tables, charts and figures, lists of major terms, and review questions for each chapter. This book will appeal to students in Master of Health Administration (MHA), Master of Public Health (MPH), Master of Public Administration (MPA), Master of Science in Nursing (MSN), health certificate programs, and junior and senior level undergraduate students in political science, public administration, public health, and public policy. In addition to serving as a core text for health policy and administration classes, the book will serve as a supplementary text for graduate level courses. 312 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -From the unique position of a decade in government service, I was given the opportunity to observe the changes in the provision of emer gency medical care across the country. In 1970, Emergency Medical Service (EMS) systems were a new and much needed development in the national health care delivery system. A systems approach to field casualty care has been progressively improved during each successive military conflict since the Civil War. These improvements were ini tiated after the rnedil:al care and evacuation disaster experienced by the Union Army of the Potomac at Bull Run on July 21, 1861. During the Civil War, major changes in administration, professional personnel, transportation, hospitals, sanitation, and medical records established patterns that have been continually refined and improved. Stimulated by the pressing demands of war surgery and coupled with parallel advances in medical care over the last century, an almost unbelievable level of performance was realized in Vietnam. Advances in field resuscitation, efficiency of aeromedical transportation, and energetic treatment of military casualties have proved to be major fac tors in the decrease in death rates of battle casualties reaching facilities: from 8% in World War I to 4. 5% in World War II to 2. 5% in Korea and to less than 2% in Vietnam.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 224 pp. Englisch.

Neuware -The topics in this book represent the presentations given at the Fifth Annual Meeting entitled 'Cardiac Surgery: Current Issues' held at the Frenchman's Reef Beach Resort, St. Thomas, U.S. Virgin Islands, November 18-20, 1993. This symposium was sponsored by the Division of Cardiothoracic Surgery, the School of Cardiovascular Perfusion and the Department of Nursing Education and Quality Assurance of Cooper Hospital/University Medical Center, the University of Medicine and Dentistry of New Jersey, Robert Wood Johnson Medical School, Camden, New Jersey, as well as the Academy of Medicine of New Jersey. Chapter authors were charged with the task of writing brief overviews of major issues related to the field of cardiac surgery. The book is specifically tailored to the needs of cardiothoracic surgeons, cardiovascular perfusion ists, allied health professionals and nursing personnel involved in all phases of caring for the cardiac surgical patient. Although intended as a reference source with emphasis on up-dated approaches applied in cardiac surgery, it is hoped that the discussion of these topiCS will compliment other texts and manuscripts. Obviously, a book of this length cannot cover the whole multidisciplinary and complex field of cardiac surgery. However, co-editors are certain that the annual appearance of this text will highlight comprehensive, new and Interesting approaches to the field of cardiac surgery.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 208 pp. Englisch.

Neuware -Some 10 years ago, Leo Apostel presented an analysis of developments taking place in genetic epistemology and artificial intelligence, and re marked that the two disciplines appeared to be converging, without one dominating or assimilating the other. In his view, significant formal and experimental progress would be required in the post-Piagetian era: ge netic epistemology would need to take into account developments in artificial intelligence, while remaining an independent discipline at the frontiers of biology, logic, and psychology. The work of David Leiser and Christiane Gillieron, both psychol ogists with a Genevan training who are concerned by the procedural aspects of intelligence, is an important contribution. Their studies, which open up new theoretical perspectives, are carried out with metic ulous attention to research methodology. Going beyond merely ad dressing criticisms about the status of Piagetian operational structures, their work will help fill the gap between genetic epistemology and cog nitive science.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 220 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -¿¿¿Progressives need a balanced federal budget morethan Conservatives, because they believe that government has an important role toplay in modern life. Lack of a long term plan to move toward a sustainablebudget crowds out short term Progressive priorities: infrastructure spendinggreen technology, education and needed governmental interventions in the shortterm to support and improve our weak economy. The federal budget is unsustainable. For all the bluster of the debt ceilingdebate, the plan passed so far does not address the changes most obviouslyneeded if we are to ever have a balanced budget again: an increase in taxes andthe next steps on health reform to address the biggest driver of our long termbudget deficit, health care costs.Slowing the rate at which health care costs are growing is a necessary, but nota sufficient condition to developing a long range balanced budget. You shouldask any politician saying they think a balanced budget is a priority onequestion: what is your health reform plan Without one, they have no hope ofachieving their goal. This book offers progressives solutions to health care reform and a balanced budget, and will be of interest to academics, students and educated readers interested in politics, public policy andgovernment finance.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 124 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Although 5-fluorouracil (Fura) is the drug of choice for the treat ment of patients with advanced colorectal cancer, this agent has limited effectiveness with a reported response rate of 10-20% and a duration of response of only 6-9 months. The large percentage of treatment failures with this agent has spurred a continuing effort to delineate the mechanism(s) of resistance to Fura and to evaluate approaches that would selectively modulate the therapeutic efficacy of this agent. The therapeutic efficacy of FUra has been attributed to its selec tive incorporation into RNA and to its inhibition of thymidylate syn thase, leading to potent inhibition of DNA synthesis. Studies of cell lines in vitro and model systems in vivo have demonstrated that although mechanism~sensitivity and resistanc; to Fura are multifactorial, in the presence of citrovorum factor (CF, 5-formyltetrahydrofolate) the site of action of Fura becomes predominantly the pronounced and pro longed inhibition of thymidylate synthase. This action is the result of stabilization of the covalent ternary complex between FdUMP, an active metabolite of FUra, 5,10-methylenetetrahydrofolates, and thymidylate synthase. This effect of CF is thus an example of the concept of meta bolic modulation.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 352 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -It is now generally recognized that the field of combinatorics has, over the past years, evolved into a fully-fledged branch of discrete mathematics whose potential with respect to computers and the natural sciences is only beginning to be realized. Still, two points seem to bother most authors: The apparent difficulty in defining the scope of combinatorics and the fact that combinatorics seems to consist of a vast variety of more or less unrelated methods and results. As to the scope of the field, there appears to be a growing consensus that combinatorics should be divided into three large parts: (a) Enumeration, including generating functions, inversion, and calculus of finite differences; (b) Order Theory, including finite posets and lattices, matroids, and existence results such as Hall's and Ramsey's; (c) Configurations, including designs, permutation groups, and coding theory. The present book covers most aspects of parts (a) and (b), but none of (c). The reasons for excluding (c) were twofold. First, there exist several older books on the subject, such as Ryser [1] (which I still think is the most seductive introduction to combinatorics), Hall [2], and more recent ones such as Cameron-Van Lint [1] on groups and designs, and Blake-Mullin [1] on coding theory, whereas no compre hensive book exists on (a) and (b).Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 492 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Second order equations with nonnegative characteristic form constitute a new branch of the theory of partial differential equations, having arisen within the last 20 years, and having undergone a particularly intensive development in recent years. An equation of the form (1) is termed an equation of second order with nonnegative characteristic form on a set G, kj if at each point x belonging to G we have a (xHk~j ~ 0 for any vector ~ = (~l' . '~m)' In equation (1) it is assumed that repeated indices are summed from 1 to m, and x = (x l' ¿¿¿ , x ). Such equations are sometimes also called degenerating m elliptic equations or elliptic-parabolic equations. This class of equations includes those of elliptic and parabolic types, first order equations, ultraparabolic equations, the equations of Brownian motion, and others. The foundation of a general theory of second order equations with nonnegative characteristic form has now been established, and the purpose of this book is to pre sent this foundation. Special classes of equations of the form (1), not coinciding with the well-studied equations of elliptic or parabolic type, were investigated long ago, particularly in the paper of Picone [105], published some 60 years ago.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 268 pp. Englisch.

For forty three seconds, the world's first atomic bomb plunged through six miles of clear air to its preset detonation altitude. There it exploded, destroying Hiroshima and eighty thousand of her citizens. No war had ever seen such instant devastation. Within nine days Japan surrendered. World War II was over and a nuclear arms race had begun. Fifty years later, the National Air and Space Museum was in the final stages of preparing an exhibition on the Enola Gay's historic mission when eighty-one members of Congress angrily demanded cancellation of the planned display and the resignation or dismissal of the museum's director. The Smithsonian tnstitution, of which the National Air and Space Museum is a part, is heavily dependent on congressional funding. The Institution's chief executive, Smithsonian Secretary I. Michael Heyman, in office only four months at the time, scrapped the exhibit as requested, and promised to personally oversee a new display devoid of any historic context. In the wake of that decision I resigned as the museum's director and left the Smithsonian.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 504 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Machine learning and nonparametric function estimation procedures can be effectively used in forecasting. One important and current application is used to make forecasts of ¿future dangerousness' to inform criminal justice decision. Examples include the decision to release an individual on parole, determination of the parole conditions, bail recommendations, and sentencing. Since the 1920s, 'risk assessments' of various kindshave been used in parole hearings, but the current availability of large administrative data bases, inexpensive computing power, and developments in statistics and computer science have increased their accuracy and applicability.In this book, these developments are considered with particular emphasis on the statistical and computer science tools, under the rubric of supervised learning, that can dramatically improve these kinds of forecasts in criminal justice settings. The intended audience is researchers in the social sciences and data analysts in criminal justice agencies.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 128 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Over the past several years there has been increasing information in the medical literature regarding the health benefits of a Mediterranean diet. Clinicians may not be informed on advances in nutrition, and studies have demonstrated that they do not spend much time discussing food as a means for promoting health with patients. The Mediterranean Diet: A Clinician's Guide for Patient Care is an essential new volume that serves as an update and a reference for clinicians on the Mediterranean diet. Specific diseases and the effects the Mediterranean diet have on them are outlined. Diseases and conditions that are outlined include heart disease, stroke, Alzheimer¿s, depression, cancer, allergies, asthma, arthritis and diabetes. A detailed analysis of the specific nutrients in a Mediterranean diet and the food groups containing them is also included. A useful guide containing daily meal plans and and an extensive recipe section prepared by a team of dieticians can be found in the patient resources section. The Mediterranean Diet: A Clinician's Guide for Patient Care provides a useful summary of the constituent components and health benefits of a Mediterranean diet to health professionals.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 264 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -In this edition, a set of Supplementary Notes and Remarks has been added at the end, grouped according to chapter. Some of these call attention to subsequent developments, others add further explanation or additional remarks. Most of the remarks are accompanied by a briefly indicated proof, which is sometimes different from the one given in the reference cited. The list of references has been expanded to include many recent contributions, but it is still not intended to be exhaustive. John C. Oxtoby Bryn Mawr, April 1980 Preface to the First Edition This book has two main themes: the Baire category theorem as a method for proving existence, and the 'duality' between measure and category. The category method is illustrated by a variety of typical applications, and the analogy between measure and category is explored in all of its ramifications. To this end, the elements of metric topology are reviewed and the principal properties of Lebesgue measure are derived. It turns out that Lebesgue integration is not essential for present purposes-the Riemann integral is sufficient. Concepts of general measure theory and topology are introduced, but not just for the sake of generality. Needless to say, the term 'category' refers always to Baire category; it has nothing to do with the term as it is used in homological algebra.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 120 pp. Englisch.

Buch. Condizione: Neu. Neuware -The Mathematics of Finance has been a hot topic ever since the discovery of the Black-Scholes option pricing formulas in 1973. Unfortunately, there are very few undergraduate textbooks in this area. This book is specifically written for advanced undergraduate or beginning graduate students in mathematics, finance or economics. This book concentrates on discrete derivative pricing models, culminating in a careful and complete derivation of the Black-Scholes option pricing formulas as a limiting case of the Cox-Ross-Rubinstein discrete model.This second edition is a complete rewrite of the first edition with significant changes to the topic organization, thus making the book flow much more smoothly. Several topics have been expanded such as the discussions of options, including the history of options, and pricing nonattainable alternatives. In this edition the material on probability has been condensed into fewer chapters, and the material on the capital asset pricing model has been removed.The mathematics is not watered down, but it is appropriate for the intended audience. Previous knowledge of measure theory is not needed and only a small amount of linear algebra is required. All necessary probability theory is developed throughout the book on a 'need-to-know' basis. No background in finance is required, since the book contains a chapter on options.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 304 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The present volume is the first of three that will be published under the general title Lectures in Abstract Algebra. These vol umes are based on lectures which the author has given during the past ten years at the University of North Carolina, at The Johns Hopkins University, and at Yale 'University. The general plan of the work IS as follows: The present first volume gives an introduction to abstract algebra and gives an account of most of the important algebraIc concepts. In a treatment of this type it is impossible to give a comprehensive account of the topics which are introduced. Nevertheless we have tried to go beyond the foundations and elementary properties of the algebraic sys tems. This has necessitated a certain amount of selection and omission. We feel that even at the present stage a deeper under standing of a few topics is to be preferred to a superficial under standing of many. The second and third volumes of this work will be more special ized in nature and will attempt to give comprehensive accounts of the topics which they treat. Volume II will bear the title Linear Algebra and will deal with the theorv of vectQ!_JlP. -a. ces. . . . . Volume III, The Theory of Fields and Galois Theory, will be con cerned with the algebraic structure offieras and with valuations of fields. All three volumes have been planned as texts for courses.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 232 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -As the title suggests, this book is concerned with the elementary portion of the subject of homotopy theory. It is assumed that the reader is familiar with the fundamental group and with singular homology theory, including the Universal Coefficient and Kiinneth Theorems. Some acquaintance with manifolds and Poincare duality is desirable, but not essential. Anyone who has taught a course in algebraic topology is familiar with the fact that a formidable amount of technical machinery must be introduced and mastered before the simplest applications can be made. This phenomenon is also observable in the more advanced parts of the subject. I have attempted to short-circuit it by making maximal use of elementary methods. This approach entails a leisurely exposition in which brevity and perhaps elegance are sacrificed in favor of concreteness and ease of application. It is my hope that this approach will make homotopy theory accessible to workers in a wide range of other subjects-subjects in which its impact is beginning to be felt. It is a consequence of this approach that the order of development is to a certain extent historical. Indeed, if the order in which the results presented here does not strictly correspond to that in which they were discovered, it nevertheless does correspond to an order in which they might have been discovered had those of us who were working in the area been a little more perspicacious.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 772 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Students embarking upon a colour chemistry course usually approach it by way of a general introduction and proceed to more detailed treatment of the subject when they have acquired some knowledge of its character and scope. This book has been written with the twofold purpose of serving as a guide to such students during the introductory part of their course and of supplying the needs in this field of others whose main interest is in a related branch of technology or pure chemistry. An attempt has been made to present the main features of the subject in an easily assimilable form. The great amount of published information renders the choice of material for a short book somewhat difficult, and I am keenly conscious of topics that might be thought worthy of more extensive treatment. However, a concise account cannot be comprehensive, and suggestions for further reading are provided at the end of the book. The chemistry of colouring matters can be regarded as a branch of pure chemistry, but the development of knowledge in this field has followed a course determined chiefly by the applications of dyes and pigments. It has therefore appeared appropriate to treat the subject here as a branch of technology.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 352 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Origin, Scope, and Plan of this Book In July 1962 the fiftieth anniversary of Max von Laue's discovery of the Diffraction of X-rays by crystals is going to be celebrated in Munich by a large international group of crystallographers, physi cists, chemists, spectroscopists, biologists, industrialists, and many others who are employing the methods based on Laue's discovery for their own research. The invitation for this celebration will be issued jointly by the Ludwig Maximilian University of Munich, where the discovery was made, by the Bavarian Academy of Sciences, where it was first made public, and by the International Union of Crystallo graphy, which is the international organization of the National Committees of Crystallography formed in some 30 countries to repre sent and advance the interests of the 3500 research workers in this field. The year 1912 also is the birth year of two branches of the physical sciences which developed promptly from Laue's discovery, namely X-ray Crystal Structure Analysis which is most closely linked to the names ofW. H. (Sir William) Bragg and W. L. (Sir Lawrence) Bragg, and X-ray Spectroscopy which is associated with the names of W. H. Bragg, H. G. J. Moseley, M. de Broglie and Manne Siegbahn. Crystal Structure Analysis began in November 1912 with the first papers ofW. L. Bragg, then still a student in Cambridge, in which, by analysis of the Laue diagrams _of zinc blende, he determined the correct lattice upon which the structure of this crystal is built.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 740 pp. Englisch.

Neuware -This volume of the series on 'Cerebral Cortex' deals with a variety of topics that need to be considered in our overall understanding of the functions of the cerebral hemispheres. Chapters in the first part of this volume deal with normal functions that were not covered in earlier volumes, while chapters in the latter part deal with the functioning of the cortex in various altered states. The first chapter is by Eberhard Fetz, Keisuke Toyama, and Wade Smith, and it considers the interactions that can be demonstrated to exist between cortical neurons by using the technique of cross-correlation. The second chapter is by Brent Vogt who examines the connections and functions of layer I of the cerebral cortex, a layer that has been largely ignored in the past, and he proposes that this layer probably plays an important role in learning and memory acquisi tion. This is followed by a chapter in which Oswald Steward presents a review of what is currently known about synaptic replacement following denervation of cortical neurons, and especially those in the hippocampus.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 552 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -In the past fifteen years organic photochemistry has undergone a greater change and has stimulated more interest than probably any other area of organic chemistry. What has resulted is a population explosion, that is, an ever-increasing number of organic chemists are publishing important and exciting research papers in this area. Professor Bryce-Smith in the introduc tion to a recent volume of the Specialist Periodical Report (Photochemistry, Volume 6), which reviews the photochemical literature in yearly intervals, states that 'the flood of photochemical literature is showing some signs of abatement from the high levels of two or three years ago . ' However, Volume 6 of that periodical contains 764 pages of excellent but very concise reviews. We expect the development of the mechanistic aspects of organic photo chemistry to continue at the present pace as new methods are developed to probe in increasing detail and shorter time scales the photochemical dynamics of both old and new photoreactions. Since photochemistry is no longer the sole domain of the specialist, it is relatively safe to predict a dramatic increase in the near future of the synthetic and industrial uses of organic photo chemistry .Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 604 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The aim of the editors of this volume is to use basic and ap plied studies in the field of mutagenesis to approach a problem of especial concern. The problem is that of the usage of toxic chemi cals, particularly agricultural chemicals, in ever-increasing quan tities in those parts of the world that feed the most people. Agri cultural chemicals that are in use in Pakistan are emphasized here. These are the same chemicals that are in use throughout the develop ing world, although the quantities of the different types that are used may vary from country to country, and from region to region within countries. A number of these chemicals can no longer be sold in Europe or in the United States, and it is often difficult to iden tify a scientific reason as to why they are sold at all. It is ironic that toxic chemicals are used as a humanitarian device to rid the world of Pestilence and Famine -- two of the Horsemen of the Apocalypse. If we do not wish poisonous chemicals to become the fifth Horseman of the Apocalypse, then we must begin now to identify and regulate the large-scale usage of toxic sub stances everywhere.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 456 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The biomedical community often complains of the crowded schedule of important meetings to be attended. It was thus with some reser vations when the individuals participating in this conference accepted the invitation to attend a small gathering to discuss the 'Comparative Pathophysiology of Circulatory Disturbances', held over three days in November, 1971. At the end of it they had changed their minds and were enthusiastic over the wisdom to hold meetingsof this kind. The conference was conceived some years earlier when it was apparent to the conveners that little opportunity exists in the common mammoth meetings to exchange detailed information and, p- haps more importantly, to transmit points of view between scientists of different disciplines. In particular, the voice of veterinarians and comparative biologists is not often heard by medical investigators, and vice versa. Thus, many animal models exist in nature whose investigative exploitation might make important contributions to an understanding of human disease, yet they are unknown to medical scientists. Conversely, veterinarians are often not aware of the needs of such models and their recognition is often delayed unduly. This conference, attended by investigators of various back grounds was called to help correct these deficiencies, at least in a small segment of study, that concerned with circulatory pathophysiology.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 396 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This monograph gives an up-to-date account of the original results of the author's research in the complex field of the central control over relationships which have become established in the course of evolution between the hypothalamus and the pituitary gland. The author has limited the scope of this research on logical grounds to the study of central chemically reactive structures in the regulation of the adrenal glands through the intermediary of the hypothalamo-hypophyseal system. Through the author's skill and expertise in the analysis of the extensive and sometimes complicated literature he has successfully undertaken a differential approach to the analysis of the concrete role of catecholamines, acetylcholine, and serotonin in relation to the endocrine system. The vast range of experimental investigations and results of clinical observations published in the last few decades have revealed the humoral neurosecretory factors of the hypothalamus as impor tant regulators of the princ ipal functions of the pituitary gland and, through it, of the cyclic activity of the peripheral group of endocrine glands. Until recently the region of the cascade of regulatory in fluences preceding the hypothalamus was terra incognita. It is for this reason that Evgenii Vladimirovich Naumenko's monograph ac quires its special importance for the neurophysiologist, for its author has striven, by the use of experimental methods, to ascertain in detail the nature of influences which for a long time were in terpreted as the general dogmas of an abstract 'nervism.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 208 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Coronaviruses have emerged during the past ten years from being a group of viruses causing a variety of minor veterinary and human diseases to a major virus group of both clinical significance and molecular biological interest. Against this background, two international coronavirus symposia were held in 1980 and 1983. In recent years, the pace of coronavirus research has been quickened even more by infusion of recombinant DNA technology and establishment of various animal model systems to study the pathogenesis and immunology of coronavirus infections. We therefore organized the Third International Coronavirus Symposium held at Asilomar, California in September 1986, which was attended by more than 120 participants representing a cross section of both academia and industry. This symposium provided an exciting and stimulating forum for assessing the progress made since the last triennial symposium in Netherlands and to suggest the directions for future efforts. This volume collects the scientific papers presented in this symposium. Three loosely defined areas, Molecular biology, Virus-Cell Interaction and Viral Pathogenesis, are separated. These papers very nicely summarize the current status of coronavirus research. They contain a large amount of sequence data, including the complete sequence of a 27 Kb coronavirus genome, a novel mechanism of mRNA synthesis that is unique to coronviruses, and many exciting aspects of coronavirus pathogenesis and immunology. Reflecting the growing interest in the preparation of vaccines, several papers also address the issues related to coronavirus vaccines, which is an area new to this symposium.
