This item is printed on demand - it takes 3-4 days longer - Neuware -The bibliography which follows represents an effort to provide the active or potential worker in the field of gas chromatography with references to the theory, methodology, and applications of this phase of chemistry. A review of the cited references will afford background for proposed applications, suggest possible solution of a problem, furnish an acquaintance with trends and current work being conducted, and furnish a realization of the possibilities and po tentialities of a technique for the separation, identification, and more recently-preparation of materials. To augment the numerous literature references, titles of papers presented at various scientific meetings are given. Some of these papers have not been published, but they represent a part of the literature of this technique since they indicate the progress and thinking of workers in this field, and provide the opportunity for those with mutual interests to communicate with each other for further details. To afford ready referral for additional information, references are given, when available, to Chemical Abstracts, orto the abstract in the program of the meeting. To accommodate those who may desire microfilm or photostatic copies of the published works, complete pagination is given rather than initial page references. Austin V.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book contains the proceedings of the ARW NATO Conference on 'Action of Free Radicals and Active Forms of Oxygen on Lipoproteins and Membrane Lipids: Cellular Interactions and Atherogenesis', held in Bendor, France, October 5-8,1988. Since the pioneer work of Mc Cord and Fridovitch, growing interest has been focused on the study of the role of oxyradicals role in pathology. This interest is reflected in the exponential increase in the number of papers on free radicals, the success of specialized journals and books on this theme, and the organization of national and international meetings. These meetings have discussed, from.a broad point of view, the problems concerning the mechanisms of production of free radicals, their effects on cell CO!1$tituants (lipids, proteins, nucleic acids) and cell function, the methods of analysis of these phenomena, the pathological states in which free radicals may be involved, natural biological defense systems, and the design of 'antiradical' therapies. But it is now well established that the most common target of oxy free radicals are membrane lipids because of their chemical nature (cholesterol in saturation, malonic linkage of polyunsaturated fatty acids (PUFA' and of their regular structural arrangement (monolayers in lipoproteins, bilayers in cell membranes). Thus the analysis of the products resulting from the action of oxy free radicals on PUFA is considered the best tool to indirectly evaluate the effects of tissue peroxidations, although the analytical basis for doing so is very questionable. 436 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The field of solar energy conversion has become an important discipline with a recognized potential to significantly contribute to the world supply of energy. It is diversified and encompasses a wide variety of disciplines - from mechanical engineering to physics, from biology to architecture, from ocean science to agriculture, from chemistry to atmospheric science, to name some of the major fields. It involves fields which have matured to the engineering aspects, such as the conversion of solar energy into heat or of wind into shaft work. It includes other fields in which more basic science research is necessary to unravel the micro-structures of nature, as, for example, for photovoltaic conversion or for certain bioengineering tasks. Several of these fields have elements which have been common knowledge for centuries but sometimes forgotten at times of cheap energy supplies, while others have barely started with first studies. Most of the fields have seen during the last decade a substantial advance in sophistication, in theoretical understanding, in demonstrated feasibility, in developing hardware, in field testing, with some moving into a phase of initial commercialization. 324 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The prospective reader may well ask about the particular merits of this volume, especially in view of several dozen similar offerings, each with its own excellences, and of the easy availability of symposia, conferences, con ventional reviews, abstract journals, and serial research reports. In spite of such other attractions, it seems to me that these 34 essays are among the most informative and stimulating which are now available in the areas cov ered. The editors have been successful in attracting new articles from many of the most prominent investigators now actively working at research in psychotherapy, who can therefore speak for themselves about what they are doing. Several of the articles have been in the preparatory stage for numerous years. Not only do they represent the vanguard of research, but because of the introduction of relatively new concepts in communication theory in the clinical setting which can be implemented by the new tech nology (specifically the use of sound-films and tape), they probably presage the shape of much that is to come. It is commonplace that the history of a science is closely allied to the history of the tools available. Here we see the concepts, attitudes, and working methods on this frontier being set forth frankly and concretely in ways which avoid many of the deficiencies and evasions of previous clini cal research. 676 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Cryogenics is an emerging technology filled with promises. Many cryogenic systems demand the use of nonmetallics and composites for adequate or increased performance. Thermal and electrical insulations, potting for superconducting magnets' mechanical sta bility, and composite structures appear to be some of the most significant applications. Research on nonmetallics at cryogenic temperatures has not progressed to the degree of research on metals. Nor can room temperature research be extrapolated to low tempera tures; most polymers undergo a phase transformation to the glassy state below room temperature. Research by producers, for the most part, has not been prac tical, because, except for LNG applications, the market for large material sales is not imminent. There are, however, many government stimulated developmental programs. Research on nonmetallics thus is dictated by development project needs, which require studies orien ted toward prototype hardware and specific objectives. As a result, research continuity suffers. Under these conditions, periodic topical conferences on this subject are needed. Industry and uni versity studies must be encouraged. Designers and project research material specialists need to exchange experiences and data. Low temperature-oriented research groups, such as the National Bureau of Standards and the Institute for Technical Physics - Karlsruhe, must contribute by assisting with fundamentals, interpreting proj ect data, and contributing to project programs through their materials research. 460 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This Advanced Study Institute (ASI) brought together two distinct 'schools of approach' to Quantum Electrodynamics (QED) in the presence of intense, external, electromagnetic fields, in an effort to lay a joint foundation for a needed theoretical explanation of the sharp e+ e- 'resonances' observed in the scattering of very heavy IOns. These (GSI/Darmstadt) experiments, whose history, latest reconfirmations, and most recent data were presented in three opening sessions (Bokemeyer, Koenig), show a smooth background of positron (e+) production, as a function of e+ kinetic energy. Superimposed upon this background are four very sharp peaks, of narrow widths (~ 30 KeV) and of clear experimental significance ('' 5 standard deviations). Most ofthese peaks correspond to sharp, essentially back-to-back electron-positron emission in the ions' center of mass. Following the approach of 'supercritical' potential theory (SPT), where the total ionic charge unit Z satisfies Z 137, it has been possible to provide a detailed and apparently correct understanding of the smooth e+ e- background; a coherent description of different facets of this approach, emphasizing the nature of the charged, supercritical vacuum, was described by the authors responsible for the invention of SPT (Greiner, Muller, Rafelski). In addition, predictions for related phenomena were outlined by other lecturers using the SPT approach (Bawin, Soff, SsJrensen). 456 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -The rapid development of powerful pulsed lasers is at the origin of a conside rable interest in studying the response of an atom, a molecule (or a solid) to a strong electromagnetic field. It is now possible to produce at the laboratory scale, ultra-short 13 pulses with a duration of 100 femtoseconds (10- second) and a power of the order 12 of 1 terawatt (10 Watt). Under these conditions, very high peak intensities may be obtained and electric fields exceeding typical electron binding fields in atoms are generated. The interaction of an atom or a molecule with such electromagnetic fields has a highly non-linear character which leads to unexpected phenomena. Amongst them, - above-threshold ionization (ATI) i.e. the absorption of additional photons in excess of the minimal number necessary to overcome the ionization potential and its molecular counterpart, above-threshold dissociation (ATD); - generation of very high harmonics of the driving field; - stabilization of one-electron systems in strong fields. These processes were the main topics of two international meetings which were held in 1989 and 1991 in the United States under the common name SILAP (Super-Intense Laser-Atom Physics).Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 520 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -This volume contains the lectures and seminars presented at the NATO Advanced Study Institute on Lasers in Biology and Medicine organized by the International School of Quantum Electronics at the Villa Le Pianore, Camaiore, Italy, August 19-31, 1979. Most laser applications in biology and medicine are highly interdisciplinary in nature, drawing from and pertaining to such diverse fields as the physical sciences ( (bio)physics, (bio)chemi stry) , engineering, the biological sciences (cellular research, photobiology) and finally theoretical and clinical medicine. Indeed the group of participants of the summer school did reflect this diversity both in background and interest. The presentations con tained in this volume mainly fall into two categories: tutorial lectures on the most important general subjects, intended to lay a common base for all participants, and a number of more advanced con tributions, serving the purpose of exemplifying selected but typical applications in their current state of development. Intense inter communication, lively discussion, and here and there even future cooperation were the general aims more than a detailed in-depth discussion of one or the other aspect of this large field. In this sense it is the hope of the organizing committee that, despite the inevitable limitations, a broad and reasonably representative cov erage of the field has been achieved and that this volume may be a valuable aid for newcomers to get a good start into this complex subject area for some years to corne.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 480 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -The present volume includes the large majority of papers given at the symposium entitled 'Fundamental Approaches to Plant and Animal Improvement,' held at Cali, Colombia, in November, 1972. The primary focal points were on various genetic mechanisms, including gene action and mutation, the development of phenotypic attributes, and on evolution, including that controlled by man for agricultural purposes. In fact, very little referring in any particular way to animal improvement was included, while a great deal of attention was paid to higher plants and to microorganisms. On the other hand, both the population genetics of insects and insect control were considered. Thus Genes, Enzymes, and Populations, the title given to this published work, seems to me to represent somewhat more fairly the contents than does the original symposium title. Given the intent of the symposium, which is expressed in the original title, the published record cannot be expected to be a neatly packaged presentation of some highly defined subject matter. Indeed the diverse subjects represent some, but by no means all, of the varied and dynamic scientific activities that need to be components in the improvement and production of agriculturally Significant plants at a time when world populations are rapidly increasing and shortages of food occurring. In any case, the organizers of the symposium wisely decided that considerations of environment as well as of genetics should be introduced into the thinking of the group and that physiology and molecular biology could not be ignored.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 380 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -The continuous advances in our understanding of hematology and neo plastic disorders have made possible this third volume of reviews. Their purpose is to summarize investigations which have defined new concepts, and, it is hoped, stimulate new ideas. In the choice of subjects, we have attempted to retain the balance between academic and clinical interests. We are grateful to the contributors, who have maintained the high stan dards set in the earlier volumes, and for feedback from readers. Both have helped to orient the direction of this series. It was a reader who pointed out that the title of the two earlier volumes, The Year in Hematol ogy, was misleading since it suggested a detailed review of trends and findings limited to the last year. In response to this valid comment, The Year . . . has been changed to Contemporary . . . and the scope has been expanded to encompass the kindred disciplines of hematology and oncol ogy. Another editor, Franco M. Muggia, has been added to provide addi tional expertise for the latter field. The title of the present and future volumes has been changed to Contemporary Hematology/Oncology. It has been pointed out to us that considerable ingenuity will be needed to find topics not already covered. We believe that the papers in the present volume have met this challenge. As before, the readers' comments con cerning Contemporary Hematology/Oncology will be appreciated. Joseph LoBue Albert S.

There is a very wide spectrum of management personnel, engineers in continuing education, specifiers, designers, graduate students--not to omit investors-who need this material as an intensive short course and reference work permanently at hand. Even in recession conditions the pultruded product business has grown by double-digit percentages, and this level of demand will continue as the U. S. infrastructure is renovated. Demand has stirred competition, in turn leading to product refinement. This technology development is taking place in materials, such as processable epoxy systems; in exotic but reliable production systems; and in mold/part complexity. The Handbook of Pultrusion Technology is essential to orient us in the fundamentals. The substance in Ray Meyer's treatment of this RP process is not available in any other compilation. Joseph S.

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -In this book, the fundamentals of magnetism are treated, starting at an introductory level. The origin of magnetic moments, the response to an applied magnetic field, and the various interactions giving rise to different types of magnetic ordering in solids are presented and many examples are given. Crystalline-electric-field effects are treated at a level that is sufficient to provide the basic knowledge necessary in understanding the properties of materials in which these effects play a role. Itinerant-electron magnetism is presented on a similar basis. Particular attention has been given to magnetocrystalline magnetic anisotropy and the magnetocaloric effect. Also, the usual techniques for magnetic measurements are presented. About half of the book is devoted to magnetic materials and the properties that make them suitable for numerous applications. The state of the art is presented of permanent magnets, high-density recording materials, soft-magnetic materials, Invar alloys and magnetostrictive materials. Many references are given.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 192 pp. Englisch.…
