Buch. Condizione: Neu. Neuware - Coronary flow reserve is a functional measure of stenosis severity re flecting the integrated effects of its geometry including percent stenosis, absolute lumen area, length and shape. Its clinical application has been primarily qualitative in non-invasive, perfusion imaging. Measurement of coron…ary flow reserve during routine coronary arte riography has been an elusive goal. Transit time and indicator dilution techniques for assessing coronary flow reserve at cardiac catheteriza tion are associated with marked variability compared to microspheres or flow meters, thereby making their use questionable in comparison to the precision of good quantitative arteriography. Coronary flow reserve measured by special Doppler catheters as an adjunct to coronary arte riography shows in man the value of this integrated functional measure of stenosis severity and the limitations of percent diameter narrowing as a measure of its physiologic significance. However, Doppler catheters require additional instrumentation that is not yet an integral part of coronary arteriography and provide measures of absolute coronary flow reserve only. Relative maximum flow or relative flow reserve has been demon strated to be an important independent, complimentary descriptor of stenosis severity independent of fluctuating hemodynamic conditions. The method developed for DSA by Nico Pijls, described in this book is the first approach for assessing relative coronary flow reserve as a part of routine coronary arteriography by DSA. The theory and basic con cepts are well developed, experimental validation thorough and clinical applications timely.

Buch. Condizione: Neu. Neuware - Ever since the seminal works on traveling waves and morphogenesis by Fisher, by Kolmogorov, Petrovski and Piscunov, and by Turing, scientists from many disciplines have been fascinated by questions concerning the formation of steady or dynamic patterns in reactive media. Contributions to this vol…ume have been made by chemists, chemical engineers, mathematicians (both pure and applied), and physicists. The topics covered range from reports of experimental studies, through descriptions of numerical experiments, to rather abstract theoretical investigations, each exhibiting different aspects of a very diverse field.

Buch. Condizione: Neu. Neuware - Although research in architectural synthesis has been conducted for over ten years it has had very little impact on industry. This in our view is due to the inability of current architectural synthesizers to provide area-delay competitive (or 'optimal') architectures, that will support interfaces… to analog, asynchronous, and other complex processes. They also fail to incorporate testability. The OASIC (optimal architectural synthesis with interface constraints) architectural synthesizer and the CATREE (computer aided trees) synthesizer demonstrate how these problems can be solved. Traditionally architectural synthesis is viewed as NP hard and there fore most research has involved heuristics. OASIC demonstrates by using an IP approach (using polyhedral analysis), that most input algo rithms can be synthesized very fast into globally optimal architectures. Since a mathematical model is used, complex interface constraints can easily be incorporated and solved. Research in test incorporation has in general been separate from syn thesis research. This is due to the fact that traditional test research has been at the gate or lower level of design representation. Nevertheless as technologies scale down, and complexity of design scales up, the push for reducing testing times is increased. On way to deal with this is to incorporate test strategies early in the design process. The second half of this text examines an approach for integrating architectural synthesis with test incorporation. Research showed that test must be considered during synthesis to provide good architectural solutions which minimize Xlll area delay cost functions.

Buch. Condizione: Neu. Neuware - From time to time the International Journal of Fracture has presented matters thought to be of special interest to its readers. The last special topic review was presented by Drs W.G. Knauss and AJ. Rosakis as Guest Editors in four issues, January-April 1990, under the general title of Non Linear… Fracture. It contained sections on damage mechanisms, interfaces and creep, time depen dence, and continuum plasticity insofar as they affect the mechanisms of the fracture process. Continuing this policy, which is consistent with our stated objectives, the two September issues deal with the behavior of concrete and cementious materials during fracture initiation and propagation. We hope that the ensuing state-of-the-art review will yield another instructive and timely product which readers will find useful. To assist us in presenting this subject, we have prevailed upon a well-known international expert in concrete behavior, Dr. Z.P. Bazant, Walter P. Murphy Professor of Civil Engineering, of Northwes tern University to act as Guest Editor. On behalf of the editors and publishers, I wish to thank Professor BaZant and his invited authors for undertaking this special effort. M.L. WILLIAMS Pittsburgh, Pennsylvania Editor-in-Chief September 1991 International Journal of Fracture 51: ix-xv, 1991. Z.P. Bafant (ed.), Current Trends in Concrete Fracture Research.

Buch. Condizione: Neu. Neuware - oil is the lifeblood of the World's economy. It was a critical element in two World Wars and in the Cold War, and, as recent events in the Middle East confirm, people are willing to fight for it. The cheap energy it provides, especially for transport and agriculture, was one of the main factors t…hat made possible the economic prosperity and growth that the World has enjoyed for the past fifty years and more. People rely on it everywhere, and in many forms, and they have become so accustomed to its ready availability that they take it for granted. To conceive of a world without traffic jams and airliners is unthinkable, and while not so obvious, oil lies behind every supermarket shelf, fuelling the tractor that ploughs the field and the delivery van that brings the consumer his food. Yet everyone knows that it is a finite and irreplaceable commodity, formed long ago in the geological past. What no one knows is just how finite it is. This book is an effort to try to answer that question: not in detail, but at least in orders of magnitude. More useful than the figures themselves is the discussion of the elements involved in addressing the subject. While it is impossible to predict the precise pattern of future production, which will be affected by many unforeseeable factors, one can at least begin to think in terms of resource constraint instead of an ever expanding supply of oil.

Buch. Condizione: Neu. Neuware - Oceanic basalts are the most abundant rock type found at the earth's surface, and as such they have been the subject of considerable research, particularly since the concept of sea-floor spreading became widely accepted. This book provides a review of these rocks, first dicussing how we sample th…e ocean floor and what we know about the structure of the oceanic crust, followed by an overview of the various regional settings (Pacific crust, Atlantic crust, marginal basins, seamounts and islands) and finally examines the main processes (and their interactions) which prevail during the generation and emplacement of oceanic basalt magmas. This is a volume for geologists, geochemists and geophysicists and a source of reference for advanced undergraduate students and postgraduates in these disciplines.

Taschenbuch. Condizione: Neu. Neuware - The basic accomplishment of sentence processing research in the 1960s and 70s was to establish that perceivers assign structural representa tions to sentences (Fodor et al., 1974) and they do so systematically using the formation rules of the grammar (Forster, 1979). This may sound like a…singularly unimpressive accomplishment to a contem porary linguist - mere proof of the obvious. But one must recall the extremely impoverished view of language and language processing prevalent in the U.S. in the 1950s. Processing mechanisms were thought to consist of slightly elaborated stimulus-response associations, and sentences were viewed as mere strings of concatenated words. On this view, understanding language comprehension was naturally equated with knowing how words and associations between them were learned. Consequently, language pro cessing was investigated by performing a seemingly endless series of tedious paired associate learning studies. The shift in the 1960s to a view of sentences emphasizing hierarchically organized structures con taining grammatical depencies between widely separated items was thus dramatic.

Buch. Condizione: Neu. Neuware - 'De la vaporisation et de la centralisation du Moi. Tout est la. ' Charles Baudelaire (journal entry) This anthology is my visit to Oz. On sabbatical in 1988, I chose to reeducate myself in general biology, first broadening my erudition as an immunologist, and then extending that horizon into evo…lutionary biology and embryology. I was particularly attracted to reflections on the nature of the self as an organ ismic concept. I went in search of reorientation as a confused physician scientist, and came back with this book. Baum's Wizard of Oz presented opportunities for growth, and herein lies the purpose of this volume: in providing updated statements concerning the nature of the organism from both scientific and metaphysical perspectives, we might ponder the philo sophical basis of our research in the hope of gaining insight into our endeavor, not to mention the possibility of its enrichment; it is this contem plative view of our research which offers a unique dimension to this anthology. To that end, the project follows my idiosyncratic prejudices. The anthology derives in large measure from the symposium, 'Organism and the Origin of Self' held at Boston University, April 3-4, 1990, under the auspices of the Boston University Center for the Philosophy and History of Science, with generous support of Robert Cohen and Jon Westling, and the organizational skills of Deborah Wilkes. The Symposium presented three ver sions of the Self from the vantages of embryology, evolution and medicine.

Buch. Condizione: Neu. Neuware - For a philosopher with an abiding interest in the nature of objective knowledge systems in science, what could be more important than trying to think in terms of those very subjects of such knowledge to which men like Galileo, Newton, Max Planck, Einstein and others devoted their entire lifetimes… In certain respects, these systems and their structures may not be beyond the grasp of a linguistic conception of science, and scientific change, which men of science and philosophy have advocated in various forms in recent times. But certainly it is wrong-headed to think that one's conception of science can be based on an identification of its theories with languages in which they may be, my own alternatively, framed. There may be more than one place in book (1983: 87) where they may seem to get confused with each other, quite against my original intentiens. The distinction between the objec tive knowledge systems in science and the dynamic frameworks of the languages of the special individual sciences, in which their growth can be embedded in significant ways, assumes here, therefore, much impor tance. It must be recognized that the problems concerning scientific change, which these systems undergo, are not just problems concerning language change.

Buch. Condizione: Neu. Neuware - The various efforts to develop a Marxist philosophy of science in the one time 'socialist' countries were casualties of the Cold War. Even those who were in no way Marxists, and those who were undogmatic in their Marxisms, now confront a new world. All the more harsh is it for those who worked wi…thin the framework imposed upon professional philosophy by the official ideology. Here in this book, we are concerned with some 31 colleagues from the late German Democratic Republic, representative in their scholarship of the achievements of a curiously creative while dismayingly repressive period. The literature published in the GDR was blossoming, certainly in the final decade, but it developed within a totalitarian regime where personal careers either advanced or faltered through the private protection or denunciation of mentors. We will never know how many good minds did not enter the field of philosophy in the first place due to their prudent judgments that there was a virtual requirement that the candidate join the Socialist Unity (i.e. Communist) Party. Among those who started careers and were sidetracked, the record is now beginning to be revealed; and for the rest, the price of 'doing philosophy' was mostly silence in the face of harassments the likes of which make academic politics in the West seem child's play.

Buch. Condizione: Neu. Neuware - Gastric cancer has been one of the great malignant scourges affecting man kind for as long as medical records have been kept. Until operative resection pioneered by Bilroth and others became available, no effective treatment was feasible and death from cancer was virtually inevitable. Even with r…esection by total gastrectomy, the chances of tumor eradication remained small. Over recent years, however, the situation has been changing. Some changes have resulted from better understanding of the disease, early detec tion, and better management techniques with applied clinical research, but the reasons for other changes are poorly understood. For example, the incidence of gastric cancer is decreasing, especially in westernized societies, where it has fallen from one of the most common cancers to no longer being in the top five causes of cancer death. Still it remains the number one killer of adult males in Japan and Korea. Whether the reduced incidence in western societies is a result of dietary changes or methods of food preservation, or some other reason, is as yet uncertain. Improvements in outcome have been reported from mass screening and early detection; more refined techniques of establishing early diagnosis, tumor type, and tumor extent; more radical surgical resection; and resection at earlier stages of disease.

Buch. Condizione: Neu. Neuware - To-date computers are supposed to store and exploit knowledge. At least that is one of the aims of research fields such as Artificial Intelligence and Information Systems. However, the problem is to understand what knowledge means, to find ways of representing knowledge, and to specify automated…machineries that can extract useful information from stored knowledge. Knowledge is something people have in their mind, and which they can express through natural language. Knowl edge is acquired not only from books, but also from observations made during experiments; in other words, from data. Changing data into knowledge is not a straightforward task. A set of data is generally disorganized, contains useless details, although it can be incomplete. Knowledge is just the opposite: organized (e.g. laying bare dependencies, or classifications), but expressed by means of a poorer language, i.e. pervaded by imprecision or even vagueness, and assuming a level of granularity. One may say that knowledge is summarized and organized data - at least the kind of knowledge that computers can store.

This item is printed on demand - it takes 3-4 days longer - Neuware -A famous theorem in the theory of linear spaces states thatevery finite linear space has at least as many lines aspoints. This result of De Bruijn and Erd|s led to theconjecture that every linear space with 'few lines' canbeobtaine…d from a projective plane by changing only a smallpart of itsstructure.Many results related to this conjecture have been proved inthe last twenty years. This monograph surveys the subjectand presents several new results, such as the recent proofof the Dowling-Wilsonconjecture.Typical methods used in combinatorics are developed so thatthe text can be understood without too much background. Thusthe book will be of interest to anybody doing combinatoricsand can also help other readers to learn the techniques usedin this particular field. 216 pp. Englisch.

Topics like families of support, homotopy, acyclicsheaves, base-change theorems and cohomological dimensionare considered.In the second part a homology theory for locally completelocally semialgebraic spaces over a real closed field isdeveloped, the semialgebraic analogue of classicalBore-Moore-homology. Topics include fundamental classes ofmanifolds and varieties, Poincare duality, extensions of thebase field and a comparison with the classical theory.Applying semialgebraic Borel-Moore-homology, a semialgebraic('topological') approach to intersection theory on varietiesover an algebraically closed field of characteristic zero isgiven. The book is addressed to researchers and advancedstudents in real algebraic geometry and related areas. 148 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The theory of center manifold reduction is studied in thismonograph in the context of (infinite-dimensional) Hamil-tonian and Lagrangian systems. The aim is to establish a'natural reduction method' for Lagrangian systems to theirce…nter manifolds. Nonautonomous problems are considered aswell assystems invariant under the action of a Lie group (including the case of relative equilibria).The theory is applied to elliptic variational problemsoncylindrical domains. As a result, all bounded solutionsbifurcating from a trivial state can be described by areduced finite-dimensional variational problem of Lagrangiantype. This provides a rigorous justification of rod theoryfrom fully nonlinear three-dimensional elasticity.The book will be of interest to researchers working inclassical mechanics, dynamical systems, elliptic variationalproblems, and continuum mechanics. It begins with theelements of Hamiltonian theory and center manifold reductionin order to make the methods accessible to non-specialists,from graduate student level. 156 pp. Englisch.
