Buch. Zustand: Neu. Neuware - Some 350 years ago, in his Discorsi e Dimostrationi Matematici [Galilei], Galileo Galilei discussed whether or not light propagated with a finite though very high velocity, or with infinite speed, instantaneously. The ques tion was an open one then, with prominent proponents for either position. For example, Rene Descartes argued on philosophical grounds that light dispersed itself into all of space instantaneously, whereas Galileo was more inclined toward the idea of a finite velocity. In fact, he even reported about an early experiment, which, however, would have to be refined and per 1 formed again to reach a definite conclusion. 'Sagredo: . However, of which kind, and how high might we estimate the velocity of light Is the appearance instantaneous, momentaneous, or, like other movements, temporal Could one decide this experimentally Simplicio: Daily experience teaches us, that the spreading of light be instantaneous; if in a large distance the artillery per forms shooting exercises, we see the glare of the flame without the ear perceives the sound only after some time delay, while considerable time.

Buch. Zustand: Neu. Neuware - The aim of this book is to develop an understanding and treatment of the problems of inference associated with experiments in science. Many textbooks treat inference as principally the reduction of the sample information to estimates and their marginal distribution and supposedly optimal properties. In contrast, this book emphasizes techniques for dividing the sample information into various parts addressing the diverse problems of inference that arise from repeatable experiments. An unusually valuable feature of the book is the large number of practical examples, many of which use data taken from experiments published in various scientific journals. This book has evolved from the author's courses on statistical inference. It would be a suitable text book for advanced undergraduate, Masters, and Ph.D. statistics students. It can also be used as a reference book. A background knowledge of an introductory course in probability is assumed, including the calculation and manipulation of probability functions and density functions, transformation of variables and the use of Jacobians. The author is a Distinguished Professor Emeritus of Statistics, University of Waterloo, and Professor of Statistics, Centro de Investigaci=F3n en Matemáticas, Guanajuato, Mexico. He is an Honorary member of the Statistical Society of Canada and a recipient of the Society's Gold Medal for Research. He is also an elected member of the International Statistical Institute and a Fellow of the American Statistical Association, of the Institute of Mathematical Statistics, and of the Royal Society of Canada.

Taschenbuch. Zustand: Neu. Neuware - Dear Friends of Numbers: This little book is for you. It should o er an exquisite int- lectual enjoyment, which only relatively few fortunate people can experience. May these essays stimulate your curiosity and lead you to books and articles where these matters are discussed at a more technical level. I warn you, however, that the problems treated, in spite of - ing easy to state, are for the most part very di cult. Many are still unsolved. You will see how mathematicians have attacked these problems. Brains at work! But do not blame me for sleepless nights (I have mine already). Several of the essays grew out of lectures given over the course of years on my customary errances. Other chapters could, but probably never will, become full-sized books. The diversity of topics shows the many guises numbers take to tantalize and to demand a mobility of spirit from you, my reader, who is already anxious to leave this preface. Now go to page 1 (or 127 ). Paulo Ribenboim Tantalus, of Greekmythology, was punished by continual disappointment whenhetriedtoeatordrinkwhatwasplacedwithinhisreach. 1 The Fibonacci Numbers and the Arctic Ocean Introduction There is indeed not much relation between the Fibonacci numbers and the Arctic Ocean, but I thought that this title would excite your curiosity for my lecture. You will be disappointed if you wished to hear about the Arctic Ocean, as my topic will be the sequence of Fibonacci numbers and similar sequences.

Buch. Zustand: Neu. Neuware - The emergence of multidrug-resistant tuberculosis (MDRTB) threatens TB control programs worldwide. Outbreaks of MDRTB in the United States grabbed the attention of the medical community and the general public, and subsequent surveys have found 'hot spots' of MDRTB in low- and middle-income countries on four continents. Unlike other textbooks that contain only a single chapter on MDRTB, this book is devoted to the subject. Contributions from experts from multi disciplines provide detailed descriptions, causation, molecular biology, laboratory diagnosis, treatment, prevention, and public health, aspect of this disease. This book provides an authoritative overview of MDRTB and will be a useful reference book for clinicians, scientists and other health personnel involved in the care of TB and MDRTB patients in industrialized and developing countries.

Buch. Zustand: Neu. Neuware - There have been major changes in the heat content and ice cover of the Arctic Ocean since 1990. Year after year, this observational evidence underscores the likelihood that predictions of global climatic effects will turn out to be true. Changes in the freshwater flow from the Arctic Ocean may have very significant consequences for humanity, including those alive today. It is vital that we develop the capability to predict the magnitude of such effects with far greater certainty, as well as the probability of their occurrence within a giver time frame. To do so, we need the internationally organised commitment of scientific labour and funding. This book has been written by many of the world's most knowledgable polar oceanographers, meteorologists and hydrologists, takes full account of the latest results and discusses their significance. It draws together assessments by many specialists to present an integrated view of possible future changes in the climate of the Northern hemisphere.

Buch. Zustand: Neu. Neuware - Dr. Olcbee Lee SchoolofEducation, UniversityofMiami Coral Gables, Florida 33124 I remember my excitement and appreciation several years ago when I first read World View Theory and Science Education Research by Bill Cobern (1991). It was a comprehensive, theoretical discussion ofworldview theory in science education. I am delighted to see that Cobern has taken the next step to provide empirical accountsofworldview in Everyday Thoughts about Nature. . The primary goal of the book is to understand how typical- ninth grade students and their science teachers think about Nature or the natural world, and how their thoughts are related to science. In pursuing this goal, the book raises a basicquestion about the purpose ofscienceeducationfor the public: Should science education seek to educate 'scientific thinkers' in the pattern of the science teachers Or, should science education seek to foster sound science learning within the matrices ofvari ous cultural perspectives (p. 3) The answer to this question becomes clear, thanks to Cobern's excellent research and persuasivearguments. First, this research takes a humanistic approach in understanding what students and teachers think about Nature 'through the language and ideas voluntarily expressed' (p. I). The research used multi directional prompts and encouraged students and teachers to speak freely and at length in any directions they wished. This humanistic approach is stated clearly: '[T]he research seeks to illuminate some of the various ways in which students think aboutNature withoutjudging eventhe most unorthodox perspectives' (p. 14).

Taschenbuch. Zustand: Neu. Neuware - Agriculture is a crucial component of the economies of many of the countries in transition from a centrally-planned to a market economy and the sector is by no means immune to the environmental and socioeconomic problems confronting the countries as a whole. The concept of sustainable development provides a convenient framework for the formulation of government environmental policy for such countries, especially those of them that aspire to join the EU and would thus be expected to meet EU environmental standards. For agriculture, this inevitably involves appropriate strategies for balancing crop and animal production while protecting the quality of the national soil and water resources. There is thus an urgent need to compile, exchange and evaluate current information on the quality of soils in these countries, and to assess the potential impact of new management practices on the soil and on the wider environment.

Buch. Zustand: Neu. Neuware - Financial systems around the world are undergoing a process of modernization due to many different forces. Advances in information technology, product and market innovations, and recent regional financial crises have contributed to this movement. As a result, evolution in the financial sector is leading to larger, more complex financial organizations that render inadequate the supervisory and regulatory structures currently in place. While some changes in regulatory policies have already occurred, the adaptation of supervisory oversight and regulation in the face of these new developments is expected to continue for many years to come. This book collects papers originally presented in September 1998 at the Financial Modernization and Regulation Conference co-sponsored by the Federal Reserve Banks of Atlanta and San Francisco. Revised before publication, the papers seek to identify the reasons for changes in the financial services sector, and the implications these changes pose for financial supervision and regulation. Taken together, the papers offer valuable insights on 1) the forces behind financial modernization; 2) the implications financial modernization poses for corporate structure, market discipline, and financial regulation; 3) how to price deposit insurance accurately to reflect banks' risk-taking; and 4) balancing private versus public interests and managing potentially conflicting public policy goals.

Buch. Zustand: Neu. Neuware - This important, state-of-the-art book brings together for the first time in one volume the two areas of Legacy Systems and Business Processes. The research discussed has arisen from the EPSRC research programme on Systems Engineering for Business Process Change, and the book contains contributions from leading experts in the field.Both the consumer and supplier of IT have problems with legacy systems and business process change, so Systems Engineering for Business Process Change will be of great interest to practitioners who are encountering, or likely to encounter, problems with legacy systems and business process change, as well as researchers preparing future research programmes, and those studying system and business evolution.

Buch. Zustand: Neu. Neuware - A recurring theme in a traditional introductory graduate algebra course is the existence and consequences of relationships between different algebraic structures. This is also the theme of this book, an exposition of connections between representations of finite partially ordered sets and abelian groups. Emphasis is placed throughout on classification, a description of the objects up to isomorphism, and computation of representation type, a measure of when classification is feasible. David M. Arnold is the Ralph and Jean Storm Professor of Mathematics at Baylor University. He is the author of 'Finite Rank Torsion Free Abelian Groups and Rings' published in the Springer-Verlag Lecture Notes in Mathematics series, a co-editor for two volumes of conference proceedings, and the author of numerous articles in mathematical research journals. His research interests are in abelian group theory and related topics, such as representations of partially ordered sets and modules over discrete valuation rings, subrings of algebraic number fields, and pullback rings. He received his Ph. D. from the University of Illinois, Urbana and was a member of the faculty at New Mexico State University for many years.

Buch. Zustand: Neu. Neuware - This text atlas, now in its second edition, presents in simplest form the basic diagnostic criteria used by the electron microscopist in studying neoplasms and other diseases encountered in the routine practice of pathology. Every field of electron microscopy is covered and low magnification plates are juxtaposed with higher magnifications to illustrate diagnostic features. The largest section of the book is devoted to neoplasms as this is the area in which most diagnostic problems occur. Renal glomerular disease is another important category in which ult rastructural study may be critical in diagnosis; infectious diseases, especially those of viral, protozoan, and unusual bacterial etiologies, are a third area in which electron microscopy may be used to establish or susbstantiate a diagnosis. All of these areas are comprehensively covered with concise, readable text and more than 800 first-quality images. This book is the preeminent reference for pathologists needing current information on the role of ultrastructure in diagnostic pathology.

Buch. Zustand: Neu. Neuware - Interfaces between media, whether air-water or sediment-water interfaces or organisms themselves, pose considerable problems to marine organisms attempting to live at these boundaries. In the present volume, a number of authors address various aspects of these two topics. Locations under scrutiny range from intertidal areas to the deep sea, while both macro-and meiofaunal organisms are investigated. Distribution patterns and effects of variable temperatures, pressures, and salinities are analysed. Aspects of fouling induction and prevention are also addressed. This book is intended as a progress report from the 33rd European Marine Biology Symposium held in Wilhelmshaven, Germany, in September 1998.

Buch. Zustand: Neu. Neuware - System Modelling and Optimization covers research issues within systems theory, optimization, modelling, and computing. It includes contributions to structural mechanics, integer programming, nonlinear programming, interior point methods, dynamical systems, stability analysis, stochastic optimization, bilevel optimization, and semidefinite programming. Several survey papers written by leading experts in their fields complement new developments in theory and applications. This book contains most of the invited papers and a few carefully selected submitted papers that were presented at the 19th IFIP TC7 Conference on System Modelling and Optimization, which was held in Cambridge, England, from July 12 to 16, 1999, and sponsored by the International Federation for Information Processing (IFIP).

Buch. Zustand: Neu. Neuware - In recent decades, it has become possible to turn the design process into computer algorithms. By applying different computer oriented methods the topology and shape of structures can be optimized and thus designs systematically improved. These possibilities have stimulated an interest in the mathematical foundations of structural optimization. The challenge of this book is to bridge a gap between a rigorous mathematical approach to variational problems and the practical use of algorithms of structural optimization in engineering applications. The foundations of structural optimization are presented in a sufficiently simple form to make them available for practical use and to allow their critical appraisal for improving and adapting these results to specific models. Special attention is to pay to the description of optimal structures of composites; to deal with this problem, novel mathematical methods of nonconvex calculus of variation are developed. The exposition is accompanied by examples.

Buch. Zustand: Neu. Neuware - Efficiency and Equity of Climate Change Policy is a comprehensive assessment of the economic effects of climate change policy, addressing the issues with a quantitative modelling approach. The book thus goes beyond the usual statements on the efficiency of economic instruments to identify the way gains and losses are distributed; who gains and who loses. Both the costs and benefits of climate change policies are analyzed. Most papers also provide useful information on the economic features of the Kyoto Protocol, its possible extensions, and the effect of different implementation strategies (such as the debate on emissions trading ceilings). Readership: Scientists and policy makers, students and specialists in climate related industries, members of NGOs, and policy advisors.

Buch. Zustand: Neu. Neuware - From the perspective of the investigator, Graves' disease is a fascinating disorder with unique features and opportunities for study. The discovery in 1956 that Graves' disease was caused by a humoral factor, later shown to be an antibody to the TSH receptor, was a triumph for modern investigative medicine. Rapid progress is now being made in (i) understanding the molecular interaction between autoantibodies and the TSH receptor, (ii) identifying the genes that contribute to the predisposition to disease, (iii) developing an animal model of Graves' disease, and (iv) identifying the long-sought orbital antigen in ophthalmopathy. From the clinical standpoint, although Graves' disease is eminently treatable, there is no definitive cure. None of the therapeutic options are ideal. It is hoped that rapid progress in understanding the pathogenesis of the disease will lead to the ultimate goal of some form of immunotherapy that will make antithyroid drugs, radioiodine and thyroidectomy obsolete. The chapters in Graves' Disease: Pathogenesis and Treatment represent the viewpoints of many prominent clinicians and investigators working in the field. The editors are grateful for their contributions which cover an unusually comprehensive compendium of subjects relating to the disease.

Buch. Zustand: Neu. Neuware - This timely publication fills a large gap in the ophthalmic literature which has so far lacked a monograph on the clinically very important subject of macular edema. The book presents the most up-to-date scientific concepts concerning the etiology and pathogenesis of blood retinal barrier breakdown such as tight junction associated protein dysfunction, and changes in fluid transport properties of the retinal pigment epithelium. The bulk of the book is clinically oriented and addresses novel imaging and diagnostic techniques for the detection of macular edema as well as the clinical context of a panoply of ocular diseases which induce macular edema, such as diabetes, other vasculopathies, uveitis, and many others. New light is shed on the association between highly active antiretroviral therapy and the induction of macular edema in HIV-positive patients. Novel drug treatment regimens with steroids and carbonic anhydrase inhibitors as well as new ways of applying laser and surgical therapies are also discussed in detail, and practical treatment guidelines are given. This book will be helpful for vitreoretinal specialists as well as for the practising ophthalmologist confronted with patients suffering from macular edema.

Buch. Zustand: Neu. Neuware - of UB's medical school, that UB developed its School of Arts and Sciences, and thus, assumed its place among the other institutions of higher education. Had Fillmore lived throughout UB's first seventy years, he would probably have been elated by the success of his university, and he should have been satisfied and pleased that UB remained intrinsically bonded to its community while at the same time engrafting the values and standards important to higher education's mission in the region. UB and its medical school have undergone many challenging transitions since 1846. Included among them were: (1) the completion of an academic campus in the far northeast comer of the City of Buffalo while leaving its medical, dental and law schools firmly situated in the core of downtown Buffalo; (2) the eventual relocation, after the second world war, of the law school to the newer campus in Amherst, and the medical and dental school to the original academic campus: and (3) the merger with the State University of New York System in 1962. Despite these significant transitions, any one of which could have changed the intrinsic integrity of UB and disrupted the bonding between community and university, that did not happen. To this day, the ties between community and academe persist. Fillmore and White should celebrate their success and important contribution to Buffalo and Western New York.

Buch. Zustand: Neu. Neuware - The discovery of the human T cell leukemia virus type I in the late 1970s heralded a new era in retrovirology. For the first time, it was demonstrated that a retrovirus could play a role in the development of a human disease, in this case adult T cell leukemia (ATL). Several years later, the acquired immunodeficiency syndrome (AIDS) epidemic began, and it was dem- strated that a retrovirus, originally designated the human T cell lymp- tropic virus type 3, was the causal agent of this syndrome. This virus, later named the human immunodeficiency virus type 1 (HIV-1), has since been extensively studied in terms of its pathogenesis as well as its ability to elicit immune responses. In that time, a tremendous amount of information has been obtained about the virus. Although recent drug regimens have been useful in significantly lowering viral loads and perhaps maintaining an asymptomatic state among individuals infected with HIV-1, an established 'cure' for AIDS eludes us. In addition, the effective drug therapies are very expensive, and are not available to infected people in the third world, where greater than 90% of new infections occur. Furthermore, the development of viral resistance against the drug therapies is an additional concern. Despite extensive study, no effective vaccine has been developed. One of the problems in developing an effective vaccine against HIV-1 is the ability of the virus, particularly in the immunogenic envelop glycoprotein, to undergo amino acid hypervariability.

Taschenbuch. Zustand: Neu. Neuware - For more than 25 years the Standard Model of particle physics has withstood the confrontation with experimental results of increasing precision, but this does not imply that the Standard Model can answer all questions about the ultimate constituents of nature. This book presents a critical examination of the latest experimental results and confronts them with the predictions of the Standard Model. Besides discussions of accelerator results from LEP, HERA and the TEVATRON, attention is paid to the unresolved problems of neutrino oscillations, CP violation, dark matter and cosmology. New theoretical ideas are also analyzed in order to explore possible extensions of the standard model. Realistic plans for future accelerators are presented and their physics potential is discussed, paving the way for the next generation of particle physics experiments.

Buch. Zustand: Neu. Neuware - This book presents the most recent research advances in the theory, design, control and application of robotic systems, which are intended for a variety of purposes such as manipulation, manufacturing, automation, surgery, locomotion and biomechanics. The issues addressed are fundamentally kinematic in nature, including synthesis, calibration, redundancy, force control, dexterity, inverse and forward kinematics, kinematic singularities, as well as over-constrained systems. Methods used include line geometry, quaternion algebra, screw algebra, and linear algebra. These methods are applied to both parallel and serial multi-degree-of-freedom systems. The results should interest researchers, teachers and students, in fields of engineering and mathematics related to robot theory, design, control and application. All articles in the book were reported at the seventh international symposium on Advances in Robot Kinematics that was organised in June 2000 in the beautiful ancient Mediterranean town of Piran in Slovenia. The preceding symposia of the series took place in Ljubljana (1988), Linz (1990), Ferrara (1992), Ljubljana (1994), and Piran (1996), and Salzburg (1998).

Buch. Zustand: Neu. Neuware - Regardless of the subject matter, our studies are always searching for a sense of the universal in the specific. Drawing, etchings and paintings are a way of communicating ideas and emotions. The key word here is to communicate. Whether the audience sees the work as laborious or poetic depends on the creative genius of the artist. Some painters use the play of light passing through a landscape or washing over a figure to create an evocative moment that will be both timeless and transitory. The essential role of art remains what is has always been, a way of human expression. This is the role that our participants concentrate on as they discuss art as the expression of the spirit, a creative act through which the artist makes manifest what is within him. Spirit suggests the unity of feeling and thought. Avoiding broad generalities, our participants address specific areas in orchestration with music, architecture, literature and phenomenology. Profs. Souiller, Scholz, Etlin, Sweetser, Josephs show us at what point art is an intimate, profound expression and the magic of a civilization as a whole, springing from its evolving thoughts and embodying ideals, such as the Renaissance, the Baroque, Modernism and at what point it reflects the trans formation of a particular society and its mode of life.
