Taschenbuch. Condición: Neu. Neuware - Ultrasonic visualization techniques offer many advantages in regard to the detection of both benign and malignant pathologies of the soft tissue re- gions of the human body. In the past 5 years, there has been a remarkable pro- liferation of commercially available ultrasound instrumentation with the consequence that the medical profession has become increasingly aware of the diagnostic advantages, for detection of cancer, of examination by high-frequency sound waves. Yet, despite the fact that the potential of ultrasound as a diagnostic tool for breast cancer detection was demonstrated in the United States over 20 years ago and, further, despite the high in- cidence of breast cancer in the western world, commercial instrumentation specifically designed for ultrasound scanning of the breast did not evolve in the western world during this same period. The result of this lack of standard clinical instrumentation was that the extensive clinical groundwork normally carried out by large numbers of clinicians in the early stages of applying a new diagnostic tool simply did not occur in the western world for ultrasonic examination of the breast. As indicated by Dr. Toshiji Kobayashi's tables of data in this publica- tion, individual research scientists and physicians in many parts of the world, and in particular in Japan, carried out breast visualization studies with a multiplicity of types of ultrasonic instrumentation.…

Neuware - The state of health care is reflected by perinatal and neonatal morbidity and mortality as well as by the frequencies of long-term neurological and developmental disorders. Many factors, some without immediately recognizable significance to childbearing and many still unknown, undoubtedly contribute beneficially or adversely to the outcome of pregnancy. Knowledge concerning the impact of such factors on the fetus and surviving infant is critical. Confounding analyses of pregnancy outcome, especially these past 2 or 3 decades, are the effects of newly undertaken invasive or inactive therapeutic approaches coupled with the advent of high technology. Many innovations have been introduced without serious efforts to evaluate their impact prospectively and objectively. The consequences of therapeutic misadventures character ized the past; it seems they have been replaced to a degree by some of the complications of applied technology. Examples abound: after overuse of oxygen was recognized to cause retrolental fibroplasia, its restriction led to an increase in both neonatal death rates and neurologic damage in surviving infants. Administration of vitamin K to prevent neonatal hemorrhagic disease, particularly when given in what we now know as excessive dosage, occasionally resulted in kernicterus. Prophy lactic sulfonamide use had a similar end result. More recent is the observation of bronchopulmonary dysplasia as a complication of re spirator therapy for hyaline membrane disease. The decade of the eighties opened with the all-time highest rate of cesarean section in the United States.…

Taschenbuch. Condición: Neu. Neuware - Engineering has long been thought of by the public as a profession tra ditionally categorized into such branches as electrical, mechanical, chemical, industrial, civil, etc. This classification has served its purpose for the past half century; but the last decade has witnessed a tremendous change. A continuous transition from the practical to the theoretical has made technology overlap with science, and the enlargement of scope and broad ened diversification have smeared the boundaries between traditional engi neering and scientific fields. Engineering is rapidly becoming a diversified, multidisciplinary field of scientific endeavor. This has prompted us to regard modern engineering as a science, which has as its ingredients materials, energy, and information. In our complex and technologically-oriented society organizations are flooded with an enormous amount of management information. We are now faced with problems concerning the efficient use of communicated knowledge. The steady growth in the magnitude and complexity of informa tion systems necessitates the development of new theories and techniques for solving these information problems. We demand instant access to pre viously recorded information for decision making, and we require new meth ods for analysis, recognition, processing, and display. As a consequence, information science has evolved out of necessity. Concerned with the theoretical basis of the organization, control, stor age, retrieval, processing, and communication of information both by natural and artificial systems, information science is multidisciplinary in character. It covers a vast area of subject matter in the physical and biological sciences.…

Taschenbuch. Condición: Neu. Neuware - As much by chance as by design, the present volume comes closer to having a single theme than any of our earlier volumes. That theme is the properties of nuclear strength functions or, alternatively, the problem of line spreading. The line spreading or strength function concepts are essential for the nucleus because of its many degrees of freedom. The description of the nucleus is approached by using model wave functions-for example, the shell model or the collective model-in which one has truncated the number of degrees of freedom. The question then is how closely do the model wave functions correspond to the actual nuclear wave functions which enjoy all the degrees of freedom of the nuclear Hamiltonian More precisely, one views the model wave functions as vectors in a Hilbert space and one views the actual wave functions as vectors spanning another, larger Hilbert space. Then the question is: how is a single-model wave function (or vector) spread among the vectors corresponding to the actual wave functions As an example we consider a model state which is a shell-model wave function with a single nucleon added to a closed shell. Such a model state is called a single-particle wave function. At the energy of the single-particle waVe function one of the actual nuclear wave functions may resemble the single-particle wave function closely.…

Taschenbuch. Condición: Neu. Neuware - This book is intended as an introductory exposition of those nuclear energy systems concepts which are characterized by an integrated utiliz ation of complementary nuclear processes. Basic to such systems is the notion of synergism, which herein implies the cooperative interaction of selected nuclear reactions and system components so as to provide overall advantages not possible otherwise. While the concept of nuclear energy synergism has in recent years become the focus of an increasing number of conferences, scientific papers, and institutional in-house reports, no text which encompasses the major topics of the subject at a conceptual and analytical level has appeared. It is our aim to present a systematic characterization of these emerging nuclear energy concepts suitable for the senior university student of nuclear science and engineering as well for the active pro fessional involved in nuclear energy systems planning and analysis. In addressing the subject of nuclear energy synergism we have become most conscious of the tension between realism and vision in nuclear energy technology. As developed here, our perception of nuclear energy synergism is firmly rooted in the present and then seeks to proceed toward a heightened degree of compatibility and efficacy based on an enhanced integration of relevant nuclear processes. It is our view that such conceptual considerations must assume a greater role in the emerging techological orientation of nuclear energy systems planning.…

Neuware - It has been recognized for more than a thousand years that the function of the brain, like the function of the other organs of the body, is determined by its physical, chemical, and biological properties. Evidence that even its highest functions could be explained by these properties was gathered only in recent years, however; these findings, which clearly have to be confirmed by a great deal of further experimental evidence, indicate that most, if not all, of the functions of the brain are based on its bio chemical and biophysical mechanisms. This at first hearing may sound rather simple, but the ability to understand learning, emotion, perhaps even creativity, on biological terms may well be the most important scientific discovery of all time. Few pieces of knowledge can influence our future health and well-being to the degree that understanding of mental mechanisms will. It has been clearly shown in many ways in the previous volumes of this Handbook that from the biochemical or neurochemical point of view the brain is one of the most active organs. The brain seems stable and in some respects permanent; this is evidence not of inactivity but of carefully controlled homeostasis, of dynamic rather than static equilibrium, with most components undergoing metabolic alterations.…

Neuware - Nobel symposium No. 54 on High Latitude Magnetospheric/Iono spheric Plasma Physics was organized in Kiruna, Sweden on March 22-25, 1982 by Kiruna Geophysical Institute and EISCAT Scientific Association. Some 50 leading experts from Western Europe, America and USSR were invited to the Symposium. One main purpose of the Symposium was to prepare for the intense European research effort in space plasma physics in the middle 1980's, in which the EISCAT facilities and the Swedish satellite Viking are two of the more important constituents. The prograuune of the symposium was tied to the physics of those regions of near space where EISCAT and Viking are expected to pro vide important new observational results. This is rather well covered by the t it Ie of these proceedings: High Lat itude Space Plasma Physics. The first two sessions dealt with the physics of the high latitude ionosphere and the third one with how this part of near space is affected by the properties of the solar wind and the interplanetary magnetic field. The remaining three sessions covered fairly extensively the high latitude magnetospheric physics at altitudes of 1-2 earth radii, which is the main scien tific object of the Viking project. The Prograuune COllDlittee of the Kiruna Nobel Symposium was composed of the following European scientists: P. Bauer (Issy-les-Moulineaux), R. Bostrom (Uppsala), C. G. FalthallDlar (Stockholm), T. Hagfors (Kiruna, Cochairman), o. Holt (Troms,s), B. Hultqvist (Kiruna, Cochairman), H. Kohl (Lindau), J. Oksman (Oulu), H. Rishbeth (Chilton), and L. Stenflo (Ume!).…

Taschenbuch. Condición: Neu. Neuware - Everyone working in a problem as complex as continental drift, must at some time have feit the need for an objective data summary in fields other than his own. It is a scientific dilemma that, aIthough there is evident need for researchers with competence in many fields (the classical natural scientist), the time in volved in acquiring such broad experience is so great as to ren der the task largely impossible. The alternative seems to be the team approach, and we have espoused it in tbis volume. Editors and contributors alike have tried in this book to keep the accent upon factual information and to reduce interpretation to a minimum. Interpretation there must be, however, since without it science is but an inteHectual pastime comparable to pbilately. The librarian's need to classify results in the appearance of our names upon the spine oftbis volume, however, we would like to make it clear that the book has been a truly cooperative effort and could not have succeeded but for the active help of the individual contributors, whose assistance seldom was re stricted to their chapters. Special thanks must be given to our South American coHeagues, for the tolerance with which they viewed out editorial attempts, and to Dr. E. Machens, for his careful review of the translation of his manu script. We wish also to acknowledge the help of Dr. C. W.…

Taschenbuch. Condición: Neu. Neuware - A color time-varying image can be described as a three-dimensional vector (representing the colors in an appropriate color space) defined on a three-dimensional spatiotemporal space. In conventional analog television a one-dimensional signal suitable for transmission over a communication channel is obtained by sampling the scene in the vertical and tem poral directions and by frequency-multiplexing the luminance and chrominance informa tion. In digital processing and transmission systems, sampling is applied in the horizontal direction, too, on a signal which has been already scanned in the vertical and temporal directions or directly in three dimensions when using some solid-state sensor. As a conse quence, in recent years it has been considered quite natural to assess the potential advan tages arising from an entire multidimensional approach to the processing of video signals. As a simple but significant example, a composite color video signal, such as the conven tional PAL or NTSC signal, possesses a three-dimensional spectrum which, by using suitable three-dimensional filters, permits horizontal sampling at a rate which is less than that re quired for correctly sampling the equivalent one-dimensional signal. More recently it has been widely recognized that the improvement of the picture quality in current and advanced television systems requires well-chosen signal processing algorithms which are multidimen sional in nature within the demanding constraints of a real-time implementation.…
