Buch. Condizione: Neu. Neuware - This and the next volume of the OT series contain the proceedings of the Work shop on Operator Theory and its Applications, IWOTA 95, which was held at the University of Regensburg, Germany, July 31 to August 4, 1995. It was the eigth workshop of this kind. Following is a list of the seven previous workshops with reference to their proceedings: 1981 Operator Theory (Santa Monica, California, USA) 1983 Applications of Linear Operator Theory to Systems and Networks (Rehovot, Israel), OT 12 1985 Operator Theory and its Applications (Amsterdam, The Netherlands), OT 19 1987 Operator Theory and Functional Analysis (Mesa, Arizona, USA), OT 35 1989 Matrix and Operator Theory (Rotterdam, The Netherlands), OT 50 1991 Operator Theory and Complex Analysis (Sapporo, Japan), OT 59 1993 Operator Theory and Boundary Eigenvalue Problems (Vienna, Austria), OT 80 IWOTA 95 offered a rich programme on a wide range of latest developments in operator theory and its applications. The programme consisted of 6 invited plenary lectures, 54 invited special topic lectures and more than 100 invited session talks. About 180 participants from 25 countries attended the workshop, more than a third came from Eastern Europe. The conference covered different aspects of linear and nonlinear spectral prob lems, starting with problems for abstract operators up to spectral theory of ordi nary and partial differential operators, pseudodifferential operators, and integral operators. The workshop was also focussed on operator theory in spaces with indefinite metric, operator functions, interpolation and extension problems.

This item is printed on demand - it takes 3-4 days longer - Neuware -The main part of this paper concerns Toeplitz operators of which the symbol W is an m x m matrix function defined on a disconnected curve r. The curve r is assumed to be the union of s + 1 nonintersecting simple smooth closed contours rOo r -. . . - rs which form the positively l oriented boundary of a finitely connected bounded domain in t. Our main requirement on the symbol W is that on each contour rj the function W is the restriction of a rational matrix function Wj which does not have poles and zeros on rj and at infinity. Using the realization theorem from system theory (see. e. g . - [1]. Chapter 2) the rational matrix function Wj (which differs from contour to contour) may be written in the form 1 (0. 1) W .

This item is printed on demand - it takes 3-4 days longer - Neuware -It is well known that basic science can trigger an invention of considerable technological and commercial importance. Indeed basic science and invention are often inextricably linked, each being able to catalyse the other. To engender such developments it is important that there should be good communication between the scientist and the technologist. The field of membrane biotechnology is a growing field where such communication is increasingly taking place and where new inventions are occurring. This book provides an overview of this developing field. It contains chapters by scientist and technologists working in the field of Membrane Biotechnology. The chapters cover the latest advances in basic science as well as some recent technological applications. The basic topics include the application of dynamic X-ray diffraction to lipid water systems, FTIR spectroscopy applied to membrane proteins, fluorescent analogues of phosphoinositides, studies of platelet activating factor, antibody binding to model membranes and phospholipase C induced fusion. The technological topics described include the development of new haemocompatible materials based upon biomembrane mimicry, new lung surfactant materials, drug delivery systems including liposomes and the development of new biosensors including Langmuir Blodgett films. The meeting showed that there are many other useful applications in the pipeline. The potential for new polymeric drug delivery systems, of ion selective systems based on the knowledge of ion-channel protein structures, of new plastics for cell growth and cellular engineering for artificial organs. These are among the interesting developments that are emerging in this field. 356 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book is devoted to one of the central problems of contemporary thinking, for which c.P. Snow in 1959 coined the phrase of the 'Two Cultures'. In this concept, human endeavour is directed on one side to the (forward-looking) sci ences (mathematics, physics, chemistry, biology, etc.) and on the other side to the (backward-looking) humanities (including psychology, linguistics, sociology, etc.). In this dichotomy Snow saw no possibility of unification. On the other hand the urge towards self-consistency and harmony in the mental and spiritual lives of both man and society as a whole is clearly one of the major forces of creativity, both scientific and artistic. This force aims at the unification of the 'Two Cultures' in order to build an integrated self-consistent system for our intellectual life. Some attempts in this direction have been made before, and will be described in this book. It is our aim to contribute to the achievement of an integrated mental life on the basis of information theory. In order to construct our model, we examine the laws of information theory, leading us to the deduction of the main laws inherent in both 'cultures'. Thus, we consider the evolution of both non-living and living matter, human behaviour, the phenomenon of language, the sphere of aesthetics, etc. We hope that our work will be useful both for researchers (who are trying to derive different integral theories) and for various other 'consumers' of scientific knowledge (meaning broad circles of intellectuals). 200 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Among the various theories proposed to account for the process of aging, the free radical theory is of practical interest since it includes the possibility of retarding this process by administrating natural or synthetic antioxidants and free radical scavengers. The book 'Free Radicals and Aging' summarizes knowledge accumulated during recent years in 42 reviews written by experts in the field. Aspects of free radical involvement in the intrinsic aging process and in age-related diseases, as well as the importance of the pro-antioxidant balance throughout life are discussed. Epidemiological studies from several European countries are reported showing correlations between low plasma levels of essential antioxidants and the occurence of coronary heart disease, cancer and cataract formation. Appropriate nutrition as well as prophylactic and therapeutic use of antioxidants are considered. This book represents a milestone in the field of age-related free radical biology and medicine.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Since the appearance of photosynthesis on our planet, all living organisms have been facing a new abundant, extremely reactive element, oxygen. This element is used for the synthesis of highly energetic compounds, but can also generate molecules capable of damaging constituents of living structures, including proteins, nucleic acids and lipids. It is therefore no surprise that all biological organisms have evolved multiple and sophisticated ways to reduce the detrimental effects of oxygen. For cells and tissues of highly organized animals, particularly cells of the immune system, superoxidation products play an important role, via oxidative stress, in activation, inflammation and viral and bacterial infections. We must be grateful to Drs. C. Pasquier, C. Auclair, L. Packer and R. Olivier for having brought together many specialists in an international meeting held in Paris in March 1993, at the Ministry of Research. This book comprises an impressive amount of recent knowledge, a real mine for the reader in this fast developing field of research. Furthermore, we should not forget that this basic research may lead in the future to new therapeutic approaches to the most important pathologies of the latter part of this century, including AIDS. 380 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Proteases, Protease-Derived Peptides and Protease Inhibitors Many physiological as weil as pathophysiological processes are mediated by proteases and the products of their actions, protease-derived peptides. However, the uncontrolled activity of proteases can be extraordinarily destructive and dangerous to normal biologie systems. As a result, biology has gone to great lengths to control the activities of the proteases involved in these systems by developing aseries of both highly specific (regulatory) and non-specific (protective) anti-proteases. The protease/anti-protease balancing activities include the normal homeostatic processes of clotting and clot lysis, hormonal regulation of blood pressure and the control of the inflammatory response represented by both the humoral (the kallikrein-kinin and complement systems) and cellular (neutrophil and macrophage derived proteases) components of the inflammation. Examples of successful therapies directed at these protease dependent systems include the use of warfarin and heparin to control thrombosis and streptokinase or tissue plasminogen activator (tPA) for the acceleration of clot dissolution. Similarly, the use of angiotensin converting enzyme (ACE, a type of limited activity protease or peptidase) inhibitors has made a significant impact on the treatment of hypertension. Lastly, the restitution of normal antiprotease levels by the infusion of the purified protein in patients with genetic alpha-1-antiprotease deficiency is regularly being used to reduce the rate of lung function 1055 caused by the unopposed activity of human neutrophil elastase in these individuals. 260 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The present volume contains manuscripts of lectures or topics related to the lectures which were given at the conference on 'Inverse Problems' at the mathematical Research Institute at Oberwolfach. The conference took place during the week of May 18-24, 1986, and was managed by the editors. Recalling Professor Joseph Keller's paper entitled Inverse Problems, American Mathematical Monthly, 83 (1976), we give two direct quotes. 'We call two problems inverses of one another if the formulation of each involves all or part of the solution of the other. Often, for historical reasons, one of the two problems has been studied extensively for some time, while the other is newer and not so well understood. In such cases, the former is called the direct problem, while the latter is called the inverse problem. ' 'The main sources of inverse problems are science and engineering. Often these problems concern the determination of the properties of some inaccess ible regions from observations on the boundary of that region. ' Often, inverse problems are not well posed. This increases the difficulty in their analysis and numerical solution. As can be seen from the table of content of this volume, the conference covered inverse problems in scattering theory, seismology, tomography, estimation of coefficients and source terms in parabolic and elliptic differential equations, the inverse Sturm-Liouville problem, and numerical methods. The editors wish to thank Professor M. Barner and his co-workers of the Mathematical Research Institute for their help in creating the conference. 196 pp. Englisch.

On this occasion, Japanese historians of mathe matics organized the History of Mathematics Symposium which was held at the Sanjo Conference Hall of the University of Tokyo on August 31 and September 1, as one of the related conferences of the Congress. The symposium was officially sponsored by the Executive Committee of the ICM 90, the History of Science So ciety of Japan, and the International Commission on the History of Mathematics. The Executive Committee consisted of Murata Tamotsu (Chairperson, Momoyama Gakuin University), Sugiura Mitsuo (Vice-Chairperson, Tsuda College), Sasaki Chikara (Secretary, The University of Tokyo), Adachi Norio (Waseda University), Nagaoka Ryosuke (Tsuda College until 1990, now Daito Bunka University), and Hirano Yoichi (Treasurer, Tokai University). The symposium emphasized the following three fields of study: (1) mathe matical traditions in the East, (2) the history of modern European mathematics, and (3) interaction between mathematical research and the history of mathemat ics. These fields were chosen mainly because, first, the symposium was related to the ICM, the most important congress of working mathematicians, and, second, the Kyoto ICM was held in a non-Western country for the first time. The sym posium consisted of the two Sessions: Session A for invited speakers and Session B for short communications. 262 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -The authors cover two general topics: basic engineering economics and risk analysis in this text. Within the topic of engineering economics are discussions on the time value of money and interest relationships. These interest relationships are used to define certain project criteria that are used by engineers and project managers to select the best economic choice among several alternatives. Projects examined will include both income- and service-producing investments. The effects of escalation, inflation, and taxes on the economic analysis of alternatives are discussed. Risk analysis incorporates the concepts of probability and statistics in the evaluation of alternatives. This allows management to determine the probability of success or failure of the project. Two types of sensitivity analyses are presented. The first is referred to as the range approach while the second uses probabilistic concepts to determine a measure of the risk involved. The authors have designed the text to assist individuals to prepare to successfully complete the economics portions of the Fundamentals of Engineering Exam.Table of Contents: Introduction / Interest and the Time Value of Money / Project Evaluation Methods / Service Producing Investments / Income Producing Investments / Determination of Project Cash Flow / Financial Leverage / Basic Statistics and Probability / Sensitivity AnalysisSpringer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 220 pp. Englisch.

Es ist aus Vorlesungen der Autoren an der TU München, der TU Darmstadt und der Universität Hamburg entstanden. Der Inhalt des Buches wurde insbesondere auf mathematische Bachelorstudiengänge zugeschnitten und hat sich als Basis entsprechender Vorlesungen sowie für eine anschließende Vertiefung im Bereich der Optimierung bewährt. Der Umfang entspricht zwei zweistündigen oder einer vierstündigen Vorlesung, wobei etwa in gleichem Umfang sowohl unrestringierte Optimierungsprobleme als auch Optimierungsprobleme mit Nebenbedingungen behandelt werden.Im Teil über die unrestringierte Optimierung werden sowohl Trust-Region- als auch Liniensuch-Methoden zur Globalisierung behandelt. Für letztere wird ein ebenso leistungsfähiges wie intuitives Konzept der zulässigen Suchrichtungen und Schrittweiten entwickelt. Die schnelle lokale Konvergenz Newton-artiger Verfahren und ihre Globalisierung sind weitere wichtige Themengebiete. Das Kapitel über restringierte Optimierung entwickelt notwendige und hinreichende Optimalitätsbedingungen und geht auf wichtige numerische Verfahren, insbesondere Sequential Quadratic Programming, Penalty- und Barriereverfahren ein. Der Bezug von Barriereverfahren zu den aktuell intensiv untersuchten Innere-Punkte-Verfahren wird ebenfalls hergestellt.Springer Nature c/o IBS, Benzstrasse 21, 48619 Heek 160 pp. Deutsch.

HILBERT [226, p. 163] Etwas mehr als 100 Jahre sind vergangen, seit in den Mathemati schen Annalen der sechste und letzte Teil von CANTORS fundamenta ler Arbeit Über unendliche lineare Punktmannichfaltigkeiten erschie nen ist. Damit war die Mengenlehre geboren und mit ihr eine prinzipiell neue Auffassung des Unendlichen in der Mathematik, verkörpert in CANTORS Theorie der transfiniten Zahlen. Diese Theo rie hat HILBERT als «die bewundernswerteste Blüte mathematischen Geistes und überhaupt eine der höchsten Leistungen rein verstandes mäßiger menschlicher Tätigkeit» bezeichnet. Anfangs unbeachtet oder abgelehnt, zu Ende des vorigen Jahrhunderts zunehmend anerkannt und verwendet, durch die Ent deckung der Antinomien erneut erschüttert, ist die Mengenlehre in ihrer heutigen axiomatisierten Gestalt eines der Fundamente der Mathematik. Die Tatsache, daß alle mathematischen Begriffe auf mengentheoretische Begriffe zurückgeführt werden können, hat ei nige Autoren sogar zu der Behauptung veranlaßt, die gesamte Ma thematik sei letztendlich mit der Mengenlehre identisch. Wenn uns allerdings eine solche Ansicht als eine ungerechtfertigte Überbeto nung des Formalen gegenüber dem Inhaltlichen erscheint, so ist doch unbestritten, daß die mengentheoretische Durchdringung der Mathematik neben der Entstehung des strukturellen Denkens und der Verwendung der axiomatischen Methode ein Wesenszug der mo dernen Mathematik ist. Das hat in zahlreichen Ländern bis in denSchulunterricht hinein gewirkt. 262 pp. Deutsch.
