Taschenbuch. Condizione: Neu. Neuware -The Buccaneer Gas and Oil Field Study has been the most comprehensive research project to date concerned with assessing the ecological effects of offshore production activities. It took nearly five years to complete and involved almost 30 individual research groups. All of the raw data have… been archived with NOAA's Environmental Data and Information Services, and detailed technical reports have been deposited with the National Technical Information Service so the interested investigator should be able to gain access to them. However, we felt that it would be desirable to present a distillation of our more significant findings in a form that was more readily available to the scientific and lay community. Thus, we conducted a symposium. on the study during EXPOCHEM '80 at the Astrohall, Houston, Texas during October, 1980. This volume comprises the proceedings of that symposium. All but two of the papers presented are included in this book. Manuscripts were not received from Dr. D. A. Wiesenburg (Texas A&M University: Volatile Hydrocarbons) or Dr. J. Tillery (Southwest Research Institute: Trace Metals), but these topics are adequately covered by other authors. An introductory chapter was added to place the study in its proper perspective and to provide some background material on the Buccaneer Field, a brief chapter on biocides was inserted since this topic generated much dis cussion at the symposium, and a bibliography is provided to direct the interested reader to sources of additional published infor mation on the Study.

Taschenbuch. Condizione: Neu. Neuware -In 1968 when Cell Walls and Membranes was published it was still reasonable to attempt to write a book covering the whole subject. Accordingly this edition of the book had something to say about walls from micro-organisms and plants as well as about membranes from bacteria and animal cells.… A decade later this is manifestly impossible. Knowledge about almost all the subjects has grown explosively, par ticularly about membranes and the biosynthesis of macromolecules. Moreover aspects of the subject that were still in a relatively primitive state ten years ago have grown into highly sophisticated subjects worthy of extended treatment. The result is that the present book has had to be confined to structures and functions relating to only one division of the biological kingdom, namely micro-organisms. Even then severe limitations have had to be made to keep the task within the time available to the authors and their expertise. A few of the titles of chapters such as those on the isolation of walls and membranes, the structure of the components of bacterial and micro-fungal walls and their biosynthesis remain from the earlier book. These chapters have been almost completely rewritten and a number of quite new chapters added on topics such as the action of the antibiotics that inhibit bacterial wall syn thesis, on the function of bacterial membranes, and the bacterial autolysins.

Taschenbuch. Condizione: Neu. Neuware -A 'New Looking Glass' for Behavioral Medicine In 1984, John Briggs, a science writer and specialist in interdisciplinary studies teaching at the New School for Social Research, and F. David Peat, a physicist who was for many years a fellow with the National Research Council of Canada, publi…shed a book about the revolutions that were taking place in physics, mathematics, chemistry, biology, and neu rophysiology and about the scientists whose new theories were changing our understanding about the nature of the universe. The title of their book was Looking Glass Universe, after Lewis Carroll's classic story of Alice and her friends, Through the Looking Glass. Briggs and Peat's book is a well-written, challenging volume about human beings and how they think about old problems in new and sometimes startling ways. I mention Briggs and Peat's book only partially because I happen to have a personal interest in the potential applications of new ways of looking at and thinking about nature and data derived from modern physics and systems theory for health psychology and behavioral medi cine (e. g. , Schwartz, 1984). In a letter Wolfgang Linden wrote to me on January 23,1987, he shared with me (at my request) his rough thoughts about his personal goals for this book.

Taschenbuch. Condizione: Neu. Neuware -The discipline of stream ecology has grown exponentially along with most other areas of science in the last three decades. The field has changed from a fish management-dominated poor-sister of limnology to a discipline with theoretical constructs and ecological insights as rich as those in…any area of ecology. A focus on energy transformations, nutrient turnover and the storage and processing of organic substrates has greatly enhanced the development of current paradigms. For example, the data base on microbial-biochemical invertebrate interactions in streams is now very extensive. A survey of the stream ecology literature reveals the central role played by H.B. Noel Hynes, whom I believe to be the world's premier lotic ecologist. Professor Hynes produced the major text in the field ('The Ecology of Running Waters') which has served both as an integrative review and as a bridge between the fish-water quality orientation of the fifties and sixties to the process oriented, nutritional resource-watershed perspectives of the seventies. It should also be noted that Professor Hynes' book, 'The Biology of Polluted Waters', served as a basic reference for the earlier period and he has published over 150 research papers, the great majority in stream ecology, spanning four decades.

Taschenbuch. Condizione: Neu. Neuware -This book explores both non parametric and general statistical ideas by developing non parametric procedures in simple situations. The major goal is to give the reader a thorough intuitive understanding of the concepts underlying nonparametric procedures and a full appreciation of the prope…rties and operating characteristics of those procedures covered. This book differs from most statistics books by including considerable philosophical and methodological discussion. Special attention is given to discussion of the strengths and weaknesses of various statistical methods and approaches. Difficulties that often arise in applying statistical theory to real data also receive substantial attention. The approach throughout is more conceptual than mathematical. The 'Theorem-Proof' format is avoided; generally, properties are 'shown,' rather than 'proved.' In most cases the ideas behind the proof of an im portant result are discussed intuitively in the text and formal details are left as an exercise for the reader. We feel that the reader will learn more from working such things out than from checking step-by-step a complete presen tation of all details.

Taschenbuch. Condizione: Neu. Neuware - To any professional concerned with exceptional children, it would be the greatest understatement to say that the courts and legislatures have had a tremendous impact on the field of speeial education. Especially in the last decade, a flood of litigation filed to develop and define the righ…t to education of previously unserved handicapped children has left no special education teacher, school adminis trator, nurse, educational psychologist, or pediatrician unaffected-either be cause these professionals are daily called upon to help children, or because they may come forward as witnesses on behalf of children who are the subjects of special education meetings, individualized education programs, placement hear ings, or judicial proceedings. Thus, for these people, questions regarding a student's legal rights are immediate and pervasive. This book developed out of the need to provide nonlegal professionals with a lawyer's view of the huge body of court cases and federal laws and regulations that affect their practice as well as their students and clients. An introductory chapter provides the historical basis of the current interface between law and special education. The Education for All Handicapped Children Act of 1975 and Sec tion 504 of the Rehabilitation Act of 1973, and their regulations promulgated in 1977, are the major national laws in the field ~nd are therefore described in Chapters 2 and 3.

Taschenbuch. Condizione: Neu. Neuware - Recently, much progress has been made with echocardiography and Doppler techniques and these ultrasound methods have grown in importance and reliability as non-invasive diagnostic procedures for many cardiovascular disorders. The objective of this t~xtbook is to offer a detailed yet concis…e overview of the echocardiographic diagnosis of the various cardiovascular diseases. The book focuses upon the practical echocardiographic (including Doppler) exam ination. Accordingly, the fundamental principles of echocardiography and the Doppler techniques (pulsed and continuous wave and color flow mapping are covered briefly but comprehensively). A copious amount of representative figures and illustrations is included so that the reader is able to understand the clinical application of each modality in the various cardiovascular pathologies and the echocardiographic diagnosis. In keeping with the concept of an integrated echocardiographic examination, the two-dimensional, M-mode and Doppler echocardiographic findings are included in many of the diseases. Usually, the echocardiographic examination is approached first by two-dimensional imag ing to give an understanding of the anatomical correlations, if necessary adding M-mode to clarify the time course of intracardiac movements, and secondly by each Doppler technique to evaluate the hemodynamic conditions. When familiar with these approaches, one can make not only the diagnosis of many cardiovascular diseases with echocardiography alone, but also the rational and expeditious management of patients. Today, some of the cardiac diseases (Atrial Myxoma, Atrial Septal Defect, Infective endocarditis and so forth) have been oper ated based only on echocardiographic findings.

Taschenbuch. Condizione: Neu. Neuware -Biobanks are promising instruments of biomedical research and of transnational medicine in particular. Ethical, legal and social issues associated with biobanking, however, have recently led to a more critical view on this concept. All efforts addressing these concerns have been grounded on… well-established standards of biomedical ethics such as informed consent procedures, protection of individual autonomy, benefit sharing etc. By additionally highlighting the widely neglected aspect of trust, this book aims at broadening the horizon of the ELSI-debate and thus filling a gap in current research on biobanking. The contributions of leading experts and junior researchers cover a wide field of disciplines relevant for biobanking including law, ethics, medicine, public health, social sciences, philosophy and theology. 280 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware - Probability theory is a branch of mathematics dealing with chance phenomena and has clearly discernible links with the real world. The origins of the sub- ject, generally attributed to investigations by the renowned french mathe- matician Fermat of problems posed by a gambling contemporary… to Pascal, have been pushed back a century earlier to the italian mathematicians Cardano and Tartaglia about 1570 (Ore, 1953). Results as significant as the Bernoulli weak law of large numbers appeared as early as 1713, although its counterpart, the Borel strong law oflarge numbers, did not emerge until 1909. Central limit theorems and conditional probabilities were already being investigated in the eighteenth century, but the first serious attempts to grapple with the logical foundations of probability seem to be Keynes (1921), von Mises (1928; 1931), and Kolmogorov (1933). An axiomatic mold and measure-theoretic framework for probability theory was furnished by Kolmogorov. In this so-called objective or measure- theoretic approach, definitions and axioms are so chosen that the empirical realization of an event is the outcome of a not completely determined physical experiment -an experiment which is at least conceptually capable of indefi- nite repetition (this notion is due to von Mises). The concrete or intuitive counterpart of the probability of an event is a long run or limiting frequency of the corresponding outcome.

Taschenbuch. Condizione: Neu. Neuware - As pediatric cardiology becomes more and more neonatal cardiology and even fetal cardiology, Neonatal Heart Disease by Robert M. Freedom, MO, Leland N. Benson, MD, and Jeffrey F. Smallhorn, MB is extraordinarily timely. Neonatal Heart Disease consists of 50 chapters by 25 distinguished con…tributors and is a worthy successor to The Neonate With Congenital Heart Disease by Richard D. Rowe, MD and his colleagues (1968 and 1981). The first ~dition of this book in 1968 established Richard D. Rowe, MD as the father of neonatal cardiology. As most pediatric cardiologists now know, Dick Rowe died on January 18, 1988 after a brief illness. It will therefore come as no surprise that the present volume is dedicated to this great and gentle man. Nor will it come as a surprise that I have been asked to devote this Foreword to Richard D. Rowe, MD, pioneering neonatal cardiologist and incomparable personal friend. What can one say about Dick Rowe Well, there are at least two very different tales. There is Dick Rowe the public man -the factual account of Dick Rowe's achievements as a physician, educator, and research man - the Dick Rowe that virtually 'everyone' knows. And then there is Dick Rowe the private man -the extraordinary human being who only his personal friends were privileged to know. I shall try to tell something of both stories. First, the public man - the factual account - is really quite amazing.

Taschenbuch. Condizione: Neu. Neuware -The discipline of stream ecology has grown exponentially along with most other areas of science in the last three decades. The field has changed from a fish management-dominated poor-sister of limnology to a discipline with theoretical constructs and ecological insights as rich as those in…any area of ecology. A focus on energy transformations, nutrient turnover and the storage and processing of organic substrates has greatly enhanced the development of current paradigms. For example, the data base on microbial-biochemical invertebrate interactions in streams is now very extensive. A survey of the stream ecology literature reveals the central role played by H.B. Noel Hynes, whom I believe to be the world's premier lotic ecologist. Professor Hynes produced the major text in the field ('The Ecology of Running Waters') which has served both as an integrative review and as a bridge between the fish-water quality orientation of the fifties and sixties to the process oriented, nutritional resource-watershed perspectives of the seventies. It should also be noted that Professor Hynes' book, 'The Biology of Polluted Waters', served as a basic reference for the earlier period and he has published over 150 research papers, the great majority in stream ecology, spanning four decades. 452 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -A 'New Looking Glass' for Behavioral Medicine In 1984, John Briggs, a science writer and specialist in interdisciplinary studies teaching at the New School for Social Research, and F. David Peat, a physicist who was for many years a fellow with the National Research Council of Canada, publi…shed a book about the revolutions that were taking place in physics, mathematics, chemistry, biology, and neu rophysiology and about the scientists whose new theories were changing our understanding about the nature of the universe. The title of their book was Looking Glass Universe, after Lewis Carroll's classic story of Alice and her friends, Through the Looking Glass. Briggs and Peat's book is a well-written, challenging volume about human beings and how they think about old problems in new and sometimes startling ways. I mention Briggs and Peat's book only partially because I happen to have a personal interest in the potential applications of new ways of looking at and thinking about nature and data derived from modern physics and systems theory for health psychology and behavioral medi cine (e. g. , Schwartz, 1984). In a letter Wolfgang Linden wrote to me on January 23,1987, he shared with me (at my request) his rough thoughts about his personal goals for this book. 348 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware - Die moderne Strahlentherapie ist eine auBerst komplexe MaBnahme. Es werden therapeutische Eingriffe vorgenommen, die sich sowohl in kurativer als auch palliativer Beziehung sehr niitzlich auswirken konnen, die aber auch, wie jede andere effektive Therapie, nachteilige Folgen haben konnen.…Es handelt sich urn die Ausiibung einer arztlichen Kunst, die auf einer ganzen Reihe von Kenntnissen aufbauen muB, ohne welche die Behandlung nur Stiickwerk bleiben und unweigerlich zum Anstieg von MiB erfolgen und sogar zu Schaden fiihren miiBte. Die vornehmlich kurative Behandlung bei den einzelnen Geschwiilsten wird in Band XIX und XX behandelt. Wie man beispielsweise die allgemeine von der speziellen pathologischen Anatomie trennt, so ist es auch sinnvoll, von einer allgemeinen und speziellen Strahlentherapie zu sprechen. Wir glauben, daB es sowohl niitzlich als auch notwendig ist, die allgemeine Strahlentherapie in einem eigenen Band getrennt zu be arbeiten, weil eine Zusammenfassung nicht nur nicht existiert, sondern bei dem raschen Fortschritt un serer Kenntnisse einem realen Bediirfnis entspricht.

Taschenbuch. Condizione: Neu. Neuware - Few advances in cardiovascular medicine have so captured the inter est of physicians and the public alike as has coronary artery bypass surgery. Cardiologists who lived through the era of false hopes and frustrations of previous' operations' for coronary artery disease can fully appreciate… what this major advance offers to their patients. The number of papers on this topic presented at national meetings attest to its popularity, but also make it increasingly difficult for anyone to assimilate all the data. Practitioners who must consider coronary artery bypass surgery for their patients may thus have difficulty in coming to some rational decision regarding the indications for the operation and its consequences. Depending on the 'authority' that one reads, there is still some controversy as to which patients are candidates for coronary artery surgery. This monograph on the prac tice of coronary artery bypass surgery, therefore, comes as a welcome boon to cardiologists, surgeons, internists, and general practitioners who must consider referring their patients for such surgery. It presents a balanced and reasonable picture of the overall subject, in addition to containing important information on such topics as opera tive technique and economic impact. Dr. Miller has done an outstand ing job in bringing together in one text the important considerations related to the evaluation of patients, the natural history of coronary artery disease and the benefits and problems associated with bypass surgery.

Taschenbuch. Condizione: Neu. Neuware - Global attention in scientific, industrial, and governmental commumtIes to traces of toxic chemicals in foodstuffs and in both abiotic and biotic environ ments has justified the present triumvirate of specialized publications in this field: comprehensive reviews, rapidly published progress… reports, and archival documentations. These three publications are integrated and scheduled to pro vide in international communication the coherency essential for non duplicative and current progress in a field as dynamic and complex as environmental con tamination and toxicology. Until now there has been no journal or other publica tion series reserved exclusively for the diversified literature on 'toxic' chemicals in our foods, our feeds, our geographical surroundings, our domestic animals, our wildlife, and ourselves. Around the world immense efforts and many talents have been mobilized to technical and other evaluations of natures, locales, magnitudes, fates, and toxicology of the persisting residues of these chemicals loosed upon the world. Among the sequelae of this broad new emphasis has been an inescapable need for an articulated set of authoritative publications where one could expect to find the latest important world literature produced by this emerging area of science together with documentation of pertinent ancil lary legislation.

Taschenbuch. Condizione: Neu. Neuware -The advances in the theory of diffraction gratings and the applications of these results certainly determine the progress in several areas of applied science and engineering. The polarization converters, phase shifters and filters, quantum and solid-state oscillators, open quasi optical dis…persive resonators and power compressors, slow-wave structures and patter forming systems, accelerators and spectrometer; that is still far from being a complete list of devices exploiting the amazing ability of periodic structures to perform controlled frequency, spatial, and polarization selection of signals.Diffraction gratings used to be and still are one of the most popular objects of analysis in electromagnetic theory. The further development of the theory of diffraction gratings, in spite of considerable achievements, is still very important presently. The requirements of applied optics and microwave engineering present the theory of diffraction gratings with many new problems which force us to search for new methods and tools for their resolution. Just in such way there appeared recently new fields, connected with the analysis, synthesis and definition of equivalent parameters of artificial materials - layers and coatings, having periodic structure and possessing features, which can be found in natural materials only in extraordinary or exceptional situations.In this book the authors present results of the electromagnetic theory of diffraction gratings that may constitute the base of further development of this theory which can meet the challenges provided by the most recent requirements of fundamental and applied science.The following issues will be considered in the book Authentic methods of analytical regularization, that perfectly match the requirements of analysis of resonant scattering of electromagnetic waves by gratings; Spectral theory of gratings, providing a reliable foundation for the analysis of spatial - frequency transformations of electromagnetic fields occurring in open periodic resonators and waveguides;Parametric Fourier method and C-method, that are oriented towards the efficient numerical analysis of transformation properties of fields in the case of arbitrary profile periodic boundary between dielectric media and multilayered conformal arrays;Rigorous methods for analysis of transient processes and time-spatial transformations of electromagnetic waves in resonant situations, based on development and incorporation in standard numerical routines of FDTD of so called explicit absorbing boundary conditions;New approaches to the solution of homogenization problems - the key problem arising in construction of metamaterials and meta surfaces;New physical results about the resonance scattering of pulse and monochromatic waves by periodic structures, including structures with chiral or left-handed materials;Methods and the results of the solutions of several actual applied problems of analysis and synthesis of pattern creating gratings, power compressors, resonance radiators of high capacity short radio pulses, open electromagnetic structures for the systems of resonant quasi optics and absorbing coatings. 408 pp. Englisch.
