Taschenbuch. Condizione: Neu. Neuware - Dieses Buch soll ein Bericht über den Prozess Einstein sein. Es enthält das Material über die Diskussion um die Relativitätstheorie in der UdSSR seit 1950. Von 1951 bis 1955 wurde Einstein durch die offizielle Parteiphilosophie der UdSSR in den Anklagezustand versetzt. Der Prozess gipfelte in der Aufforderung, die Relativitätstheorie zu verwerfen und durch eine materialistische 'Theorie schneller Bewegungen' zu ersetzen. Selbst der Name 'Relativitätstheorie' sollte aus den physikalischen Lehrbüchern verschwinden. Die Anklage wurde vertreten von der ideologischen Führungsschicht der gewaltigsten irdischen Macht unseres Zeitalters. Der Angeklagte, in der Reife seines Lebens vor die vehementesten Angriffe gestellt, kam nur durch sein Werk zu Wort. Dies genügte jedoch, dass sich unter den sowjetischen Physikern und Philosophen noch zur Zeit Stalins mannhafte Stimmen der Verteidigung fanden. 1955 wurde der Prozess mit der offiziellen Anerkennung der Relativitäts theorie durch die Parteiphilosophie abgeschlossen. Es war ein Sieg der Wahrheit über die Gewalt. Die Folgen mussten das Ansehen der kommunistischen Ideologie erschüttern. Es hatte sich herausgestellt, dass zwischen der angeblich einzig wissenschaftlichen Philosophie und der exaktesten Naturwissen schaft, der Physik, ein Abgrund klafft, den zu überbrücken die Sowjet philosophie bis heute bemüht ist. Andererseits begannen die sowjetischen Physiker, wachgerufen durch die Appelle der Philosophen, ihr eigenes Weltbild mit adäquaten Methoden zu durchdenken. Diese ganze Ent wicklung ist von hohem Wert für eine Diagnose der geistigen Struktur der Sowjetgesellschaft.

This item is printed on demand - it takes 3-4 days longer - Neuware -When I entered the graduate program in philosophy at the University of Pittsburgh in 1961, Nicholas Rescher had just joined the department of philosophy' to begin, with Adolf Grunbaum, the building of what is now a philosophy center of worldwide renown. Very soon his exceptional energy and versatility were in evidence, as he founded the American Philosophical Quarterly, generated a constantly rising stack of preprints, pursued impor tant scholarly research in Arabic logic, taught a staggering diversity of histori cal and thematic courses, and obtained, in cooperation with Kurt Baier, a major grant for work in value theory. That is all part of the record. What may come as a surprise is that none of it was accomplished at the expense of his students. Papers were returned in a matter of days, often the next class meet ing. And so easily accessible was he for philosophical discussion that, since (inevitably) we shared many philosophical interests, I asked him to serve as my dissertation advisor. My work in connection with this project led to a couple of journal articles while his, characteristically, led to a book. Our dis cussions certainly helped me, and while they may also have had some small influence on him, in the end our views were quite distinct. I was not only allowed complete independence, but was positively encouraged to think of my own ideas and to develop them independently. The length and breadth of Rescher's bibliography defy belief. 252 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The Colloquium at Wiesbaden was the seventh in a series organized by the Societe Universitaire Europeenne de Recherches Financieres (SUERF) at intervals since 1969. The titles, places and dates of previous Colloquia are noted on page ii, with brief particulars of the ensuing publications. From the beginning, the emphasis has been on money and finance in a European setting, and the most recent Colloquium, held in Wiesbaden for the three days beginning on September 29, 1977, followed this well-established pattern. The subject, 'New Approaches in Monetary Policy', was divided into four aspects, each discussed in separate commissions, as described in the General Report (since the languages used by SUERF are English and French, it appears in the original French on page 327, and in an English translation, on page 355. Three other chapters and the Preface are in French. ) The separate commissions, each with its own chairman and rapporteur, were addressed by the authors of the specially written papers, all experts, active in their fields, and they also led the discussions. M. Raymond Bertrand, the President ofSUERF, was Chairman for the Colloquium as a whole, which was in plenary session for the opening and closing meetings. The Rapporteur General was Professor Paul Coulbois, whose report is mentioned above. Attendance at the Colloquium has risen over the years, and so has the number of papers presented. 408 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Meteorology is by nature a multidisciplinary and transnational subject and COST cooperation has proved to be a flexible and suitable framework at European level for meteorological activities such as the standardisation of observation techniques and harmonised transmission of meteorological data. Although meteorology is not covered by a specific Community programme as such, various Community actions dealing with meteorology are now included in the EEC research programme on climatology (the 'EPOCH' programme - 1989-92) of mechanisms of extreme and sudden concerning particularly the study meteorological events, in order to predict catastrophies and consequently to reduce human and material losses. In the context of COST cooperation, which is supported by the Commission of the European Communities, the COST 73 project (1986-1991) associates 16 countries in Western Europe with the aim of setting up a weather radar network providing real-time measurements of rain, snow or hail precipitations. In this project, radar data are transmitted and combined if appropriate with satellite data - in one or more 'compositing centres' of the participating countries, in order to improve weather forecasting. Together with the COST 73 Management Committee, the Commission of the European Communities organized a seminar on this matter, in Brussels on 5-8 September 1989, at the half-way stage of the project. 600 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The date: September 30, 1880 The place: A private observatory in Hastings-on-Hudson Profession of the observer: A medical doctor The instrument: An l1-inch Clark refractor. The significance of that night marked one of the truly great turning points in the development of astronomical techniques: Dr Henry Draper, a wealthy New York medical doctor, had secured the first photograph of a nebula: a 51-minute exposure on a dry gelatinobromide plate showing the wispy nebulosity of the Orion Nebula. By March 1882, Draper had secured an exposure of 137 minutes, showing far richer detail of both bright and dark features. The rest is histapy. The photographic era heralded in a universe where hints of the presence of cosmic dust were strongly alluded to: from star-forming regions such as Messier 17, to the Horsehead Nebula in Orion, to the striking dark finger in the Cone Nebula, to the magnificent dark bands in the plane of our Milky Way. 'Historically, astromomers from the very beginning have been afraid of dust. 680 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -During the revolution in earth science that has taken place in recent years, studies of the North Atlantic ocean floor and of Iceland have played an increasingly significant role. Icelandic geoscientists have followed, and taken part in, these studies with a keen interest; one of the first tasks of the Geoscience Society of Iceland was to organize an Icelandic symposium on 'Iceland and Mid-Ocean Ridges' in 1967. At the suggestion of Dr. G. Pfuason, the Society and various local research institutions formed in 1972 an Organizing Committee for an international meeting on earth science. It was decided that it should be devoted to examining the various expressions of geo~namical forces in the North Atlantic area, in particular at the ocean ridges passing through Iceland. Apart from the scientific content of such a meeting, the organizers also felt it was highly important for scientists from both sides of the Atlantic to meet in Iceland, to become acquainted with recent progress in earth science research there and to coordinate their future research projects in the area. The meeting was held in Reykj avik 1 - 7 July, 1974, and was followed by field trips in Iceland. Generous financial support from the NATO Scient'ific Affairs Division, the Inter-Union Com mission on Geodynamics, and many other sources, is gratefully acknowledged. 336 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Glaucoma simplex or open angle glaucoma is a slow, progressive illness with an insidious course which can lead to blindness. According to our con temporary state of knowledge, the illness begins with a decreased outflow of aqueous humor. This leads, sometimes after a period of decreased aqueous humor production due to a feedback mechanism, to an increase in intra ocular pressure (lOP). An elevated lOP can eventually lead to optic nerve damage, which manifests itself morphologically as glaucomatous papillary excavation and functionally in the development of a visual field defect. The classic triad of elevated lOP, papillary excavation and visual field defect, on which the diagnosis of glaucoma was also based in earlier times, is then pre sent. To this can now only be added that tonography usually shows a de crease in aqueous humor outflow and that gonioscopy must reveal an open angle. On the basis of statistical findings, Goldmann has calculated that there may be an interval of as long as 18 years between the initial increase in lOP and the development of visual field defects. This point of view (which has been confirmed in practice) that the onset of the illness can be demon strated by measurement of the lOP has introduced a new element into the discussion around glaucoma, namely, the concept of ocular hypertension. This implies simply that there is an (statistically) elevated intraocular pres sure, even though the optic nerve may not (yet) be damaged. 164 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The papers contained herein were presented at the Second International Conference on Composite Structures (ICCS/2) held at Paisley College of Technology, Paisley, Scotland, in September 1983. The Conference was organised and sponsored by Paisley College of Technology in association with the Scottish Development Agency and the National Engineering Laboratory. It forms a natural progression from the highly successful First International Conference on Composite Structures (lCCS/l) held at Paisley in September 1981. The last few decades have seen phenomenal advances in research and of composite materials with new and exciting structural development possibilities being unearthed on an almost daily basis. Composites have been rightly heralded as space-age materials of the future. However, along with the rather specialised aerospace applications a growing awareness of the wider potential of composites is also unmistakable. The extensive composite materials research programmes of the fifties and sixties are now yielding fruit in abundance, with composites being used in virtually every area of structural engineering from transportation to pressure vessels and so on. Although significant weight savings, paramount in transportation engineering, are possible, composites have gone far beyond being simply lighter than conventional materials. They offer real structural advantages with almost unbounded potential. The ability to tailor a particular matrix material to suit prevailing environmental conditions whilst maintaining adequate reinforcement to withstand applied loading is unquestionably an attractive proposition. 600 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -We have compiled a series of over 300 consecutive clses of unilateral exoph thalmos with definitive diagnosis of the causes of disease process and an adequate follow-up period. Orbital and periorbital tumors constitute 34% of this series, inflammatory diseases including thyroid disorders 50%, arteriovenous abnormalities 4%, and miscellaneous disorders 12%. All patients were thoroughly evaluated clinically and with appropriate diagnostic tests, including ultrasonography (combined A-scan and B-scan), computerized axial tomography (EMI cranial scan), and radiographic tech niques (plain films and hypocycloidal poly tomography), orbital venography, and carotid arteriography. Each test was found to have diagnostic capabil ities which complemented other studies, depending upon the specific disease process involved. No one test was entirely adequate without the others. Radiographic studies demonstrated bony abnormality in 50% of tumor cases, but in only 28% of the entire series of exophthalmos cases. Primary orbital tumors had a lower hield with radiography than did secondary tumors. Computerized tomography demonstrated diagnostic soft tissue abnormality in 86% of tumors, 43% of inflammatory diseases, and an overall yield of 62% positive results. Ultrasonography proved the most versatile test for evaluation of orbital soft tissues, with 80% positive results for tumors, 87% for inflammatory disorders, and 78% overall acurate diagnosis. 568 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Ernst G. Frankel This book has its origin in lecture notes developed over several years for use in a course in Systems Reliability for engineers concerned with the design of physical systems such as civil structures, power plants, and transport vehicles of all types. Increasing public concern with the reliability o~ systems for reasons of human safety, environmental protection, and acceptable ir. vestment risk limitations has resulted in an increasing interest by engineers in the formal applica~i0n of reliability theory to e~gineering desian. At the same time there is a demand for more effective approaches to the des~gn of procedures for the operation and use of man-made syste~s and more meaningful assessment of the risks intr)duction and use of such a system poses both when operating as designed and when operating at below design performance. The purpose of the book is to provide a sound, yet practical, introduction to reliability analysis and risk assessment which can be used by professionals in engineering, planning, management, and economics to improve the design, operation, and risk assessment of systems of interest. The text should be useful for students in many disciplines and is designed for fourth~year undergraduates or first-year graduate students. I would like to acknowledge the help of many of my graduate students who contributed to the development of this book by offering comments and criticism. Similarly I would like to thank Mrs. 440 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The theme of the conference held at the Institute of Astronomy in the summer of 1981 was 'Supernovae'. The topic was interpreted very broadly: observations in all wavebands were discussed, along with theories for the explosion mechanism and the light curves; there were papers on supernova remnants and pulsar statistics; other sessions dealt with the use of new techniques for improving supernova searches, and with the importance of supernovae for cosmogonic and cosmological studies. This book contains texts based on all the main review lectures, together with a number of shorter papers which describe new results presented at the conference. The Scientific Organising Committee, responsible for arranging the programme, consisted of J. Audouze, G. B. Brown, J. Danziger, F. Pacini, M. J. Rees (Chairman) and J. W. Truran. The conference was well attended, with over 100 visitors to Cambridge as well as many local participants. We are grateful to all those who helped with the practical organisation of the meeting, especially Dr Michael Ingham (Secretary of the Institute of Astronomy) and Mrs Norah Tate. We thank all the authors of the papers in this volume for the trouble they took in preparing written versions of their excellent lectures, and for the efforts they made to meet our ' final' deadl ine: we wish especially to thank Drs W. O. Arnett and J. M. Lattimer for help with the edi torial work. 620 pp. Englisch.

In some periods of the past Netherlands medicine has played a major role in the evolution of European medicine; today its history still enjoys much in terest even at the other side of the Ocean. In this bibliography it has been my endeavour to compile references for all that has been written on the history of Dutch medicine in our country and elsewhere in our age. The main concern of this work is with the medicine of the Northern Nether lands. However, before the end ofthe sixteenth century the Northern and South ern Netherlands were not yet divided into two separate countries; they were still politically one and for the greater part spoke the same Flemish language. So be fore their separation the present-day Belgium and Netherlands also had a com mon medical history. Therefore many entries have been included which bear on early (and sometimes later) Flemish medicine, but it has not been the inten tion to strive for completeness in this respect. 704 pp. Englisch.

Yet much remains to be done if solar heating is to reach its full potential. The Conference Committee hopes that this record of the proceedings will provide a basis for the further development of these systems. Many difficulties have been surmounted in arriving at today's position. The foundations of the growing confidence of architects and engineers are to be found in the concerted programmes of research and development mounted by ty,'o of the sponsors of the Conference the European Community and the International Energy Agency. Some of the more tangible products of these programmes have been reported here: component and system behaviour has been subjected to rigorous scientific study; new test facilities have been founded; test procedures devised; simulation methods developed and evaluated; design rules formulated and checked against measured performance. It has been apparent here that the willingness to exchange information and experiences, which has always been a feature of the solar energy scene, remains as strong as ever. A further information-sharing initiative was noted on the part of another sponsor, UNESCO - the setting-up of the European Cooperative Network on Solar Energy, involving countries from both eastern and western Europe. 1088 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Instead of the old division of the right angle in 90° of 60' at 60' each, the following division finds ever more frequent application: one quadrant has 100 grades (gr), which in their turn are sub divided decimally in decigrades (dgr), centigrades (cgr), milligrades (mgr) and decimilligrades (dmgr). In using instruments upon which the quadrant is divided into 100 equal parts, in working with a calculating machine or a slide rule the new division has all the advantages and the old system all the disadvantages. Another important advantage of the new system is that the arcs take their place in the decimal system. One fourth of a meridian of the earth is 10.000 km, also 100 X 100 cgr; hence one km equals 1 cgr of the circumference-of the earth. If the arc of a longitude gr then circle between two given points on the earth be 14,26 their distance measured along this arc is 1426 km. It further follows that 1 mgr of the meridian equals 1 hm and 1 dmgr 10 meters. This simple calculation shows that for use in schools we should confine ourselves to milligrades (1 mgr = 3',24). Experts have assured me that for most practical applications milligrades are sufficiently accurate. 180 pp. Englisch.

However, it also implies the location of a centre of diversity, frequently even a recent one, as well as the location of a preservation centre or refuge during regressive phases in less remoted periods of earth's history, and that of a possible speciation centre. The latter may have been the place of differentia tion of subspecies, or species, provided that the isolation period has been suffi ciently long. The term deliberately brings the dynamics to prominence which is inherent in the process of dispersal. This dynamics is neither properly recognized when considering ranges 'whose recent structures more or less force us to consider them ,as static entities' (DE LATTIN 1967, p. 16)\*, nor adequately taken into account by systematic typology. Yet, it is, in fact, the change that takes place in a range, which is of great significance in evolutionary genetics. In the case of range regressions which may lead to a diminution or rupture of the range pattern according to the pressure of the endogenous or exogenous triggering factors, subsequently arising distribution obstacles may result in a geographical isolation of partial populations or popula tion parts. Their sufficiently long spatial and reproductive isolation and the allele loss resulting from the change of the population size promote a divergent develop ment. 208 pp. Englisch.

The aim of this series is to highlight some of these topics that deserve particular interest. Research in the field of viral hepatitis has been very intense and successful in recent years. The hepatitis B virus is one of the best explored at the current level of virology. Not only the nucleotid sequence of the viral DNA can be decoded, but also the amino acid compounds of its genetic products are known today. Since the techniques of molecular biology have increasingly found access to clinical laboratory use, hepatitis B virus infection can serve as an example for the importance of molecular biology in clinical hepa tology. Another example for the interdependence of basic science and clini cal medicine represents the research on bile acid metabolism. The investigation of bile acids has revealed new diagnostic approaches to hepatic and intestinal disorders. Commercial kits for the routine measurement of serum bile acids in clinical laboratories by enzymatic or radioimmunologic techniques are now available. The diagnostic value of these measurements in gastroenterology and hepatology shall be defined. Another aspect of bile acid research leads to new per spectives in the treatment of gallstone disease. The dissolution of cholesterol gallstones by chenodeoxycholic acid (therapy) may be quoted as the best example for the development of new phar macotherapeutic principles derived from basic bile acid research. 156 pp. Englisch.

This pioneering work was the origin of large scale global energy surveys. At the Munich Conference of 1980, the Commission made more thorough analyses by concentrating particularly on the specific behaviour of Third World Nations. Today, in New Delhi, in keeping with the tradition established by its previous surveys, the Commission is developing a new global study, the originality of which lies in the procedure adopted in its production. Rejecting centralised forecasting models which have almost exclusively dominated the minds of researchers, the Commission recommended a decen tralised method of approach which was totally different both in its basic principles and in its implementation. Essentially, the inhabitants of the regions were to be given the opportunity of expressing their own views on their energy future, rather than imposing on them an external model and therefore external results. 332 pp. Englisch.

The main objective of this workshop was to provide a forum for the exchange of information and views on major issues relating to the fundamentals of character izing the inelastic constitutive material behavior. Comments on the Aims of the Workshop, by Drs. William Snowden and Thomas Bache, pp. 1-5, outline reasons for holding this workshop, and provide further background. The format of the workshop was designed to optimize the interaction between researchers whose primary interest is material characterization and numerical analysts whose primary interest is the development and practical use of large computer codes.

This symposium was organized by the Japanese National Committee for the Organization of International Tsunami Symposium, 1981. The opening and closing ceremonies of the symposium were held at Sendai and Kamaishi, respectively, and eight sessions at Sendai and two sessions at Of una to were arranged. About 140 scientists and engineers including accompanied persons from ten countries participated to make the symposium a great success. In all, 55 papers were submitted prior to the opening of the symposium, of which 54 papers being orally presented, were arranged in ten sessions: Tsunami source and earthquake, warning system Tsunami waves and spectra Tsunami potential estimation Theoretical arguments on tsunami waves Tsunami generation and numerical simulation of historical tsunamis Harbor oscillations by long waves and tsunamis (1) Tsunami run up Mitigation of tsunami hazards and socio-economic effects Harbor oscillations by long waves and tsunamis (2) Historical study of tsunamis. Besides, two special popular lectures were provided for about 800 citizens in the Sanriku coastal area at Of una to Nokyo Kaikan, where the 1960 Chilean tsunami caused great destructive damages. The title of the first lecture was on the 1960 Chilean Earthquake and Tsunami by Dr. 580 pp. Englisch.

They may be toxic in the parental generation leading to impaired germ cell formation, loss of reproductive poten tial and infertility following chronic exposure. Deviant fetal development occurs as a consequence of cellular damage at sensi tive stages in development. Changes seen range from intrauterine mortality and structural malformation to growth retardation with physiological and behavioural defects. Concepts on the mechanism of action of teratogens are discussed with reference to some better-known agents. Presently, regulatory authorities prefer whole animal studies in predictive safety evaluation of substances to which a pregnant woman may be exposed. Tests are conducted over one or more generations and are designed to study the influence of test com pounds upon general reproductive performance, fertility, fetal development and perinatal and postnatal behaviour. Experiments are designed to permit compounds to be tested under conditions resembling expected human exposure. Small rodents and rabbits are preferred species on account of their convenience as laboratory animals and the available knowledge regarding their reproductive behaviour, fetal development and known sensitivity to human teratogens. 324 pp. Englisch.

The Co-Chairmen of the Sympo sium were Professor G. C. Sih of Lehigh University and Professor J. W. Provan of McGill University. Among those who served on the Organizing Committee were G. C. Sih (Co-Chairman), J. W. Provan (Co-Chairman), H. Mughrabi, H. Zorski, R. Bullough, M. Matczynski, G. Barenblatt and G. Caglioti. As a result of the interest expressed at the First Symposium that was held in October 1980, in Po land, the need for a follow-up meeting to further explore the phenomena of mate rial damage became apparent. Among the areas considered were dislocations, per sistent-slip-bands, void creation, microcracking, microstructure effects, micro/ macro fracture mechanics, ductile fracture criteria, fatigue crack initiation and propagation, stress and failure analysis, deterministic and statistical crack models, and fracture control. This wide spectrum of topics attracted researchers and engineers in solid state physics, continuum mechanics, applied mathematics, metallurgy and fracture mechanics from many different countries. This spectrum is also indicative of the interdisciplinary character of material damage that must be addressed at the atomic, microscopic and macroscopic scale level. 516 pp. Englisch.

Kettering Foundation Research Laboratory and the Tennessee Valley Authority. This support has helped research progress in this broad field of science by offering a forum both for the exchange of ideas and for scientific summary and discussion as captured over the last 10 years in each of the four books published previously. Although all previous meetings were well attended, the present conference was the largest so far. 550 scien tists from 60 different countries attended the 'Leeuwenhorst Conference', re presenting the many different disciplines actively involved in research in this field: chemists, biochemists, molecular biologists, geneticists, microbiologists, plant physiologists, agriculturalists. A large number of them had to go through a difficult period to raise the necessary funds to attend. In addition, a parallel meeting of 'policymakers' from Southeast Asia, Africa and South America was held under the auspices of Crosscurrents International Institute, Dayton, OR, USA and the United Nations University, Tokyo, Japan. These participants attended some of the scientific sessions to benefit from the vision of a number of scientists at the symposium. 784 pp. Englisch.

Substances and products considered dangerous constitute almost 50% of all the payload. It is obvious that stringent regulations are required in order to minimize the risks of accidents. These regulations, which are derived from good practice and which are based on research, have been adopted by a great number of countries. However, emergencies do occur in spite of all precautions. Such emergencies require fast and adequate response in order to confine the consequences for man and his environment to a minimum. Emergency response has political, legal, financial and technical aspects. This makes decision making extremely difficult. The papers carefully prepared and assembled in this book present an up-to-date picture of today's achievements, knowledge and difficulties that are being faced. It was the intention of Oilchem Recovery Denmark and TNO to bring the wide scatter of aspects together in a joined perspective. We also intended to spread the information on latest developments among the many people who are involved in combating calamities and in particular in decision making. Finally, we hope that this conference may help all of us to come to a safer transport of chemicals and a better aquatic environment. We thank all the authors for their magnificent contribution. 504 pp. Englisch.
