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 -This volume, published in honor of Prof. Luigi Crocco, appears when Luigi Crocco celebrates his 75th birthday of a life devoted to study, research, and teaching. The events in his life and World War II forced Luigi Crocco, as well as other Italian scientists, to look to foreign countries for the calm haven so vital to study. This notwithstanding, his scientific activity was never inter rupted, and this volume is an acknowledgment of scientists and researchers to his work and life.

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 -¿¿¿¿¿¿Now more than ever, marketing is assuming a key boundary-spanning role¿a role that also redefined the composition of the marketing organization. In this Brief, the marketing organization¿s integrative and mutually reinforcing components of marketing activities, customer value-creating processes, networks, and stakeholders are delineated within their boundary-spanning roles. Expanding upon his article published in the Journal of the Academy of Marketing Science in 2011, Tomas Hult draws thematic marketing insights from the integration of thirty-one organization theories to advance knowledge on the boundary-spanning marketing organization within four areas: strategic marketing resources, marketing leadership and decision making, network alliances and collaborations, and the domestic and global marketplace.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 88 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 -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.

Taschenbuch. Condizione: Neu. Neuware -As the aquaculture industry has expanded throughout the world, it has embraced the experiences of many fields of study to meet increasing technological challenges. The complexities of modern hatchery methodology, more intensive growout systems, and the application of diverse biological and physical sciences to aquatic animal husbandry have reached beyona the ability of most aquaculturists to enjoy an in-depth knowledge of all phases of the aquaculture process. More importantly, in order for tne culturist to have at hand the information necessary to make basic decisions, it requires an extensive library of textbooks and scientific literature. The Aquaculture Desk Reference serves as a concise compila tion of tables, graphs, conversions, formulas and design specifica tions useful to the aquaculture industry. It also provides examples, in a straightforward manner, of how information in tabulature can be used to derive values for specific system design and process strategies. Tables and graphs in this volume also provide back ground documentation and authority for further reference. The Aquaculture Desk Reference is a convenient source book that will alleviate the need for an extensive personal library to access basic information useful for practicing aquaculturists. Many thanks to Mrs. Ruth Aldrich for her assistance in the preparation of this book. My family, friends and associates also deserve my special appreciation for their encouragement and sup port.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 220 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Applications that require a high degree of distribution and loosely-coupled connectivity are ubiquitous in various domains, including scientific databases, bioinformatics, and multimedia retrieval. In all these applications, data is typically voluminous and multidimensional, and support for advanced query operators is required for effective querying and efficient processing. To address this challenge, we adopt a hybrid P2P architecture and propose novel indexing and query processing algorithms. We present a scalable framework that relies on data summaries that are distributed and maintained as multidimensional routing indices. Different types of data summaries enable efficient processing of a variety of advanced query operators.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 96 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.

Taschenbuch. Condizione: Neu. 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.

Taschenbuch. Condizione: Neu. Neuware -At 8:15 A.M., August 6, 1945, the Enola Gay released her load. 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 -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 -Efficiency is one of the most frequently used terms in thermodynamics, and it indicates how well an energy conversion or process is accomplished. Efficiency is also one of the most frequently misused terms in thermodynamics and is often a source of misunderstanding. This is because efficiency is often used without being properly defined first. This book intends to provide a comprehensive evaluation of various efficiencies used for energy transfer and conversion systems including steady-flow energy devices (turbines, compressors, pumps, nozzles, heat exchangers, etc.), various power plants, cogeneration plants, and refrigeration systems. The book will cover first-law (energy based) and second-law (exergy based) efficiencies and provide a comprehensive understanding of their implications. It will help minimize the widespread misuse of efficiencies among students and researchers in energy field by using an intuitive and unified approach for defining efficiencies. The book will be particularly useful for a clear understanding of second law (exergy) efficiencies for various systems. It may serve as a reference book to the researchers in energy field. The definitions and concepts developed in the book will be explained through illustrative examples.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 180 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 -Each gem deposit-whether of primary origin in the parent rocks; or secondary as alluvial placers in valley floors, river gravels, or the sand of oceanic shelves presents an eloquent chronicle of the Earth's life story. It reveals to the expert the prodigious processes which formed the present crust of our planet, of which this volume discloses a small but exciting detail. The materials of the Earth's crust are the rocks. In this book, the author expounds on how they were formed, why they altered, why they became the cradles of precious gemstones, how they are categorized, and how they are now exploited by man. What initiates the growth of gemstones How do they crystallize Why do gemstones of the same species, originating from different sources, vary What causes the occurrence of varieties Why do diamonds, unlike other precious stones, occur not near the Earth's surface in its crust, but deep down beneath it in the upper mantle These are only a few of the entrancing subjects discussed in this enlightening volume. The reader learns that the Earth is surprisingly alive and altering constantly-sometimes through slow and equable changes and at times by violent and tremendous cataclysms, events from which gemstones issue.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 164 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -As traced by Uichael Bradbury in his recently published monograph, The Concept of a BZood-Brain Barrier, the idea of a scientific challenge is just about as old as the twentieth century. Curiously, it remains undefined. Is it a structure or structures as some use the term, or is it a reciprocal per meability, a force-flow relationship, as do others, or is it a group of processes, some more specialized than others Depend ing upon the observer, the method, and what is observed, it seems to be each of these or all. This Symposium takes as its focus of interest the micro vasculature of the brain and includes considerations of blood flow, the properties of vessel walls and the control of flow and permeability. In addition perturbations that change the characteristics of the flow of materials are given attention. By changing the usual focus of interest, the organizers, Drs. Suddith and Eisenberg, have given a fresh outlook to the subject and now, by publication of the Proceedings, have arranged for wide availability of these interesting papers. Keasley Welch v PREFACE A symposium on the cerebral microvasculature and its function in the blood-brain barrier was held at The University of Texas Medical Branch, Galveston, in the summer of 1979.

Taschenbuch. Condizione: Neu. Neuware -In this volume the policy of review by anonymous referees and minor correction by the editor has been continued, but perhaps should not be extended without an agreed policy statement by the Society. Our choice is minimal revision with rapid publication or proper review with some delay in publication. The editor wishes to express his gratitude to Ann Richardson, Joann Fish, Lance Johnson, and Philip Weinbrecht for their invaluable help in the preparation of this volume. Ian S. Longmuir v BRIEF HISTORY OF ISOTT The Society endured a long gestation period. During the 1960s its formation was discussed at a number of international meetings devoted to oxygen in biological systems. Prominent among a great number of such gatherings were those held at the Institute of Diseases of the Chest, London 1960; Bedford College, London 1963; Queen Elizabeth College, London 1963; and the Seventh Bad Oeynhausen Conference, 1967. At first, reservations were expressed about the desirability of forming a highly specialized society which might not achieve the 'critical mass' necessary for its continued existence. However, the 1971 meeting in the Max Planck Institut fur Arbeitsphysiologie, Dortmund, answered these doubts, and Dr. Melvin Knisely commenced planning a very successful inaugural meeting in South Carolina. At this meeting in 1973 in Charleston and Clemson, the Society was formed with the customary remit of the promotion of scientific exchanges.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 672 pp. Englisch.

Laskin Biosciences Research Exxon Research and Engineering Company Linden, New Jersey I was contacted in the Fall of 1981 by Professors Martin Dworkin and Palmer Rogers, of the University of Minnesota and asked to participate in the orgnization of the 1983 conference in the series, 'Interface Between Biology and Medicine'. They and the other members of the advisory committee had the vision to realize that this was a time to depart somewhat from the traditional theme, since one of the major areas of interest in the biological and related sciences these days is that of biotechnology in a broader sense than its impact on medicine alone. In designing the format of the Conference, we considered another factor. There has been a plethora of conferences, symposia, and meetings on biotechnology over the past few years, and the faces and topics have become rather familiar. There has been a strong emphasis on the development of the technology and the 'biotechnology industry'; less attention has been paid to the science behind it. One might get the impression from some of these meetings and from the popular press that biotechnology has just recently sprung up, apparently full blown; the very fundamental scientific discoveries and the great body of 1 ALLEN I. LASKIN 2 continuing research that forms that basis for the technology is often obscured.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 592 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -In the last six years, a remarkable series of stUdies have demonstrated an intimate relationship between red cell metabolism and the function of the cell as an organ of gas transport. First came the demonstration of binding of organic phosphocompounds of the red cell to hemoglobin; this was followed by studies that demonstrated modification of hemoglobin oxygen affinity by such binding. At present we are in an exhilirating phase of accrual of data showing that the levels of these phosphorylated inter mediates can be rapidly altered in the red cell to modulate hemo globin function. At one time it was said that the red cell was an inert bag full of hemoglobin. Now we know not only that the cell has an active metabolism crucial to its viability, but that this metabolism is just as crucial to the whole organism in the proper adjustment of oxygen transport. On October first, second and third, 1969, red cell biochemists, general biochemists, geneticists, cardio-pulmonary physiologists, exercise physiologists, experts in blood storage, and represen tatives from many other disciplines met in the Towsley Center for Continuing Medical Education at the University of Michigan, Ann Arbor, to present recent findings and discuss developments in this new interdisciplinary field. The meeting was dedicated to Dr. Alfred Chanutin, Professor Emeritus of the University of Virginia, to honor his retirement in 1967 and in recognition of his great contributions to the studies outlined in the first paragraph of this preface.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 416 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This volume contains the papers presented at the Inter national Symposium on 'Cirrhosis, Hepatic Encephalopathy and Ammonium Toxicity', held in Valencia, Spain, November 27-29, 1989. Hepatic cirrhosis as well as other liver failures usual ly lead to hepatic encephalopathy which is an important cause of death in occidental countries. However the molecular bases of the pathogenesis of hepatic encephalopathy remain unclear and several hypotheses have been proposed. Hyperammonemia is considered one of the main factors responsible for the mediation of hepatic encephalopathy. Therefore, a part of the book is devoted to the effects of hyperammonemia on cerebral function, ammonia and amino acid metabolism, brain microtobules, astrocytes and synaptic trans mission and their possible role in the pathogenesis of hepatic encephalopathy. Carnitine has a remarkable protective effect against acute ammonium intoxication. Thus some results regarding this effect are also presented, as well as the clinical use of car nitine. The alterations of the metabolism of ammonia and of seda tives in liver diseases and their clinical implications are also discussed. The possible role of altered GABA-ergic neurotransmission on the pathogenesis of hepatic encephalopathy has received considerable attention recently. Results of these studies and those on benzodiazepine receptor ligands are presented as well as those on the hypothesis of the role of altered synaptic plasma membrane on the pathogenesis of hepatic encephalopathy.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 288 pp. Englisch.

Buch. Condizione: Neu. Neuware -Despite advances in detection and treatment, cancer remains a source of pain and distress to patients and of complex challenges to the loved ones caring for them. The trend toward shorter hospital stays in particular has increased the physical, psychological, and financial burden on caregivers, often leading to adverse effects on patients.Cancer Caregiving in the United States illuminates these complex concerns with authoritative detail. This wide-ranging volume provides a comprehensive survey of cancer-related issues, including those affecting the care triad (patients-family members- professionals) and quality of care as well as the numerous physical, emotional, and financial challenges that caregivers may need to confront. Sources of caregiver difficulty at each stage of the disease, from diagnosis to end of life, are explored. Each chapter analyzes its topic in terms of practice, research, education, and policy,providing a wealth of literature reviews, assessment and care models, interventions, and recommendations for future study and practice.Coverage includes:Caregiving issues for cancer patients with long-term, short-term, and intermittent needs.Family caregivers as members of the treatment team.The impact of health disparities on caregivers.Cancer care policy and advocacy.End-of-life issues for cancer caregivers.Legal, financial, and ethical issues.Cancer Caregiving in the United States is a core reference for researchers, professionals/scientist-practitioners, and graduate students in such caregiving fields as clinical psychology, social work, nursing, public health and medicine, social policy, and educational policy.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 352 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 -The human motor system is unique. It talks, walks and can play the piano from a remarkably early age. But it is difficult to study. One cannot impale single neurones with electrodes or lesion discrete areas of the nervous system in man. However, data gleaned from such elegant experiments in lower species that walk on four feet may not reflect the organisation of human motor mechanisms. John Rothwell is one of a small band of human-motor physiologists who have followed the dictum 'The proper study of mankind is man'. In this book, he brings together what is known about human motor physiology in an eminently readable and critical fashion. Of course, there is a stimulating symbiosis between animal and human experimental motor physiology, and this is effected by the integration of critical information that can only be obtained from work on animals with what is known about man. Many disciplines have interest in the mechanisms of human voluntary movement - physiologists, psychologists, physiotherapists and clinicians, be they neurologists or those working in orthopaedics, physical medicine or rehabilitation. All will find John Rothwell's book invaluable. To the beginner it provides an excellent introduction to the subject. To the expert it presents a coherent review of current knowledge and areas of uncertainty. What is abundantly clear is how much more remains to be discovered about how man controls movement. The stimulus provided by this volume will be invaluable to thought and experiment.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 344 pp. Englisch.

Buch. Condizione: Neu. Neuware -This research monograph summarizes a line of research that mapscertain classical problems of discrete mathematics and operationsresearch - such as the Hamiltonian Cycle and the Travelling SalesmanProblems - into convex domains where continuum analysis can be carriedout. Arguably, the inherent difficulty of these, now classical,problems stems precisely from the discrete nature of domains in whichthese problems are posed. The convexification of domains underpinningthese results is achieved by assigning probabilistic interpretation tokey elements of the original deterministic problems. In particular,the approaches summarized here build on a technique that embedsHamiltonian Cycle and Travelling Salesman Problems in a structuredsingularly perturbed Markov decision process. The unifying idea is tointerpret subgraphs traced out by deterministic policies (includingHamiltonian cycles, if any) as extreme points of a convex polyhedron in a space filled with randomized policies.The above innovative approach has now evolved to the point where thereare many, both theoretical and algorithmic, results that exploit thenexus between graph theoretic structures and both probabilistic andalgebraic entities of related Markov chains. The latter includemoments of first return times, limiting frequencies of visits tonodes, or the spectra of certain matrices traditionally associatedwith the analysis of Markov chains. However, these results andalgorithms are dispersed over many research papers appearing injournals catering to disparate audiences. As a result, the publishedmanuscripts are often written in a very terse manner and use disparatenotation, thereby making it difficult for new researchers to make use of the many reported advances.Hence the main purpose of this book is to present a concise and yeteasily accessible synthesis of the majority of the theoretical andalgorithmicresults obtained so far. In addition, the book discussesnumerous open questions and problems that arise from this body of workand which are yet to be fully solved. The approach casts theHamiltonian Cycle Problem in a mathematical framework that permitsanalytical concepts and techniques, not used hitherto in this context,to be brought to bear to further clarify both the underlyingdifficulty of NP-completeness of this problem and the relativeexceptionality of truly difficult instances. Finally, the material isarranged in such a manner that the introductory chapters require verylittle mathematical background and discuss instances of graphs with interesting structures that motivated a lot of the research in this topic.More difficult results are introduced later and are illustrated withnumerous examples.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 216 pp. Englisch.
