Buch. Etat : Neu. Neuware - 'Modern Compiler Design' makes the topic of compiler design more accessible by focusing on principles and techniques of wide application. By carefully distinguishing between the essential (material that has a high chance of being useful) and the incidental (material that will be of benefit only in exceptional cases) much useful information was packed in this comprehensive volume. The student who has finished this book can expect to understand the workings of and add to a language processor for each of the modern paradigms, and be able to read the literature on how to proceed. The first provides a firm basis, the second potential for growth.…

Taschenbuch. Etat : Neu. Neuware - In July 1979, the Faculty of Pharmacy of the University of Bologna received a proposal from Professor Breccia to hold an International Conference on 'Nitroimidazoles: Chemistry, Pharmacology and Clinical Application'. Because of the great interest in these drugs in various fields, I was very pleased to accept the proposal and to give to the Conference, the sponsorship of the University of Bologna. It was an added pleasure to accept the chairmanship of the meeting, together with Professors Sensi and Adams. At the same time, the Minister of Education approved the proposal also from the Faculty of Pharmacy, to offer an advanced Course on the tOpic: 'Radiosensitizers of Hypoxic Cells'. This Course was subsequently approved by a special Committee of the NATO Scientific Programme as an Advanced Study Institute. Since the subject matter of both the Conference and the Course are closely inter-related, it was logical to plan the Conference as part of the overall Course. Bringing together specialists from quite different and apparently unrelated fields of research, but all with an interest in the study and application of one single group of drugs, is a novel idea with intriguing possibilities. The volumes of the proceedings include contributions from experts with such diverse interests as synthetic chemistry, mechanism of drug action, parasitology, anaerobic bacteria and protozoa, pharmacology and toxicology, radiation sensitizers for use in radiotherapy and the development of drugs for use in cancer chemotherapy generally.…

Taschenbuch. Etat : Neu. Neuware - Naturally occurring antinutrients and food toxicants, and those formed during food processing, adversely affect the nutri tional quality and safety of foods. Because of the need to improve food quality and safety by plant breeding, fortification with appropriate nutrients, and processing methods, and because of the growing concern about possible direct relationships between diet and diseases, research is needed to: (1) evaluate the nutritive quality and safety of crops and fortified, supplemented, and processed foods; (2) define conditions that favor or minimize the formation of nutritionally antagonistic and toxic compounds in foods; and (3) define the toxicology, metabolism, and mechanisms of the action of food ingredients and their metabolites. As scientists interested in improving the safety of the food supply, we are challenged to respond to the general need for exploring: (1) possible adverse consequences of antinutrients and food toxicants; and (2) factors which contribute to the formation and inactivation of undesirable compounds in foods. Medical research offers an excellent analogy. Studies on causes and mechanisms of disease processes are nearly always accompanied by parallel studies on preventive measures and cures. Such an approach offers the greatest possible benefits to the public.…

Taschenbuch. Etat : Neu. Neuware - Even though artificial insemination is a simple technique that has been practiced for over a century, it has long been carried out under poor conditions due to an inadequate understanding of repro ductive physiology and antagonistic socio-ethical attitudes. Accor dingly, until fairly recently it was a medical act with a limited scientific basis which was practised more or less clandestinely. The development of semen preservation has totally changed the conditions of artificial insemination, especially in regard to flexibility and safeguards in its application. Although the use of fresh semen continues, it is now clear that the future of arti ficial insemination is closely linked to semen preservation. During the past two decades, semen banks have been developed in many countries. This has most often been the result of the initiative of individual physicians in either the private or public sectors. In France, a national system of semen banks (CECOS) was begun in 1973. Although there has been cooperation within this system in the areas of both research and management, a need to com municate and compare experiences with those from other countries was perceived. Thus, the first International Symposium on Artifi cial Insemination and Semen Preservation was planned and held in Paris, France in April 1979. Thirty-seven countries were represented byihdividuals from many concerned disciplines.…

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The authors of this book have been in charge of over thirty industrial contracts of various length (from six months to three years); the companies involved covered a wide range of industrial activities, including steel making, hot and cold rolling, aerospace research, automobile manufactur ing, chemical manufacturing, coal mining, bronze casting, and mechanical engineering. All contracts were related to problems connected either with the preliminary design of production systems or with the management of these systems. The problems that the authors investigated involved not only designing and scheduling, but also the modeling, analysis, and evalua tion of production systems. The book is based to a large extent on the experience gained in working on these contracts and the mathematical procedures presented are those that have been applied during the course of work on at least one of the contracts. Moreover, the authors have always kept in mind an idea which seems pivotal in the world of industry: the difficulty in companies lies much more in determining the exact nature of a problem and defining the criteria to be taken into account, than in solving the problem itself. 408 pp. Englisch. …

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Among seismic waves generated by widely dilferent types of sources, the waves that are the most interest ing and of the longest duration are usually surface waves (which are also called normal waves, interference and channel waves, natural vibrations of layers, etc. ). These waves are distinguished by their dispersion and reso nance, and are used in many investigations - in the determination of the structure of the medium (the existence of surface layers and waveguides), in the determination of the coordinates and properties of the source (in par ticular its energy and mechanism), in the identification of subterranean exploSions, in the mapping of micro- seisms, in the tracing of storms, etc. Outlines of the wide literature concerning surface waves can be found in [2, 9, 40J. Surface waves can be classed as Rayleigh or Love waves, depending on their velocity and polarization: the displacements of particles in Rayleigh waves are parallel, and the displacements in Love waves perpendicular, to the vertical plane containing the direction of propagation (some variation from this polarization is possible close to the source or in the presence of horizontal inhomogeneities in the medium). The present work is devoted to the calculation and investigation of Love waves in a vertically layered medium. The method used is based on the spectral theory of linear differential operators. ' This method is much more effective than previously applied methods based on the approximation of the medium by a set of homogeneous layers. 108 pp. Englisch. …

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Mankind, throughout history, has strived to improve his food sources. By means of slow and empirical selections, it has been possible to greatly increase both quantity and quality of plant crops. This procedure has brought the most useful cereals to a state of refinement that seems to be difficult to further improve by the same methodology. Indeed, natural sexual mechanisms were always used to cross closely related sexually and genetically compatible organisms; the selection procedure consisted of isolating the most promi sing progenies. Obviously, by this way, plants could only share preexisting genetic pools. On the other hand, the last decade has seen drastic modifi cations of the experimental plant sciences, with the appearance of new technological possibilities. Because of this profound reshaping of our experimental ap proaches, other means can now be realistically envisaged in order to achieve similar or even higher goals. It is, for instance, possible to attempt completing sexual crosses (where both male and female gametes bring together the genetic informations necessary for growth and development of the offspring) by parasexual means by which novel genetic informa tions could possibly be added to the heritage -. At the limit, such genetic manipulations could enable man to create plants capable of producing new substances characteris tic of unrelated plants or, more generally, of other living or ganisms. Even if these possibilities might appear quite remote, the interest of Scientists has been awaken and, indeed, several at tempts to such genetic manipulations have already been made. 620 pp. Englisch.…

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -During the last ten years, the diagnostic approach to disorders of bone and mineral metabolism has benefited considerably from the development of radioimmunoassay and competitive protein binding techniques for measurements of circulating parathyroid hormone, calcitonin, and biologically active vitamin D me tabolites. Accumulated experiences with radiogrametrical and densinometric methods of quantitating appendicular bone mass now facilitate the detection of changes in bone mineral content heretofore unrecognized by routine roentgenographic vertebral analysis. During this same decade, the diagnosis of metabolic bone disease and the skeletal response to remedial therapeutic ma neuvers have also been facilitated by the routine application of the bone biopsy. Improvements in tinctorial techniques, stan dardization in methodology essential for adequate preparation of thin undecalcified specimens, and the incorporation of tetracy cline bone formation or mineralization 'markers' should now herald the 'routine' use of this diagnostic procedure. Moreover, the compilation and ready availability of reference morphometric data, spanning the prepubescent years charac terized by skeletal growth and remodeling and the later senes cent period during which bone loss normally proceeds in an un- 7 8 FOREWORD relenting fashion, allow adequate differentiation between normal age-sex-related changes in skeletal turnover attendant on skeletal maturation and aging and acquired or inherited de rangements in bone metabolism. 164 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -This volume constitutes the Proceedings of the November 7-9, 1977 Conference on PROCESSING OF CRYSTALLINE CERAMICS, held at North Carolina State University in Raleigh. It was the Fourteenth in a series of 'University Conferences on Ceramic Science' initiated in 1964 and still coordinated by a founding group of four ceramic related institutions, of which North Carolina State University is a charter member, along with the University of California at Berkeley, Notre Dame University, and the New York State College of Ceramics at Alfred University. In addition, two other ceramic-oriented schools, the University of Florida and Case-Western Reserve University, have also hosted Conferences in the series. These research-oriented conferences, each uniquely concerned with a timely ceramic theme, have been well attended by audiences which typically were both inter national and interdisciplinary in character; their published Proceedings have been well received and are frequently cited. This three day conference was concerned with (a) scientific aspects of all process steps which must be combined and controlled effectively and sequentially in producing crystalline ceramics (both oxides and nonoxides), and (b) utilization of these principles in developing processes for several classes of advanced ceramics critical to present and future technology. 700 pp. Englisch.…

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book is the proceedings of a Symposium entitled 'The Physics of Solid-Solution Strengthening in Alloys' which was held at McCormick Place, Chicago, on October 2, 1973, in association with a joint meeting of the American Society for Metals (ASM) and The Metallurgical Society (TMS) of the American Institute of Mining, Metallurgical, and Petroleum Engineers (AIME). The symposium, which was initiated and organized by the editors of this volume, was sponsored by the Committee on Alloy Phases, Institute of Metals Division, TMS, AIME, and the Flow and Fracture Section of the Materials Science Division, ASM. The discipline of Alloy Design has been very active in recent years, during which considerable stress has been placed on the roles of crystallography and microstructure in the rationalization and prediction of properties. Underestimated as a component of alloy design, however, has been the importance of physical property studies, even though physical property measurements have tradi tionally been employed to augment direct or x-ray observations in the determination of phase equilibrium (and, indeed, metastable equilibrium) boundaries. 320 pp. Englisch.…

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Turbulence, mixing and the mutual interaction of turbulence and chemistry continue to remain perplexing and impregnable in the fron tiers of fluid mechanics. The past ten years have brought enormous advances in computers and computational techniques on the one hand and in measurements and data processing on the other. The impact of such capabilities has led to a revolution both in the understanding of the structure of turbulence as well as in the predictive methods for application in technology. The early ideas on turbulence being an array of complicated phenomena and having some form of reasonably strong coherent struc ture have become well substantiated in recent experimental work. We are still at the very beginning of understanding all of the aspects of such coherence and of the possibilities of incorporating such structure into the analytical models for even those cases where the thin shear layer approximation may be valid. Nevertheless a distinguished body of 'eddy chasers' has come into existence. The structure of mixing layers which has been studied for some years in terms of correlations and spectral analysis is also getting better understood. Both probability concepts such as intermittency and conditional sampling as well as the concept of large scale structure and the associated strain seem to indicate possibilities of distinguishing and synthesizing 'engulfment' and molecular mixing. 484 pp. Englisch.…

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The present work is an attempt to provide a systematic treatment of genetic linkage in diploid heredity. Part A presents a general account of statistical methods which can be brought to bear on the problem. The primary emphasis is on the practical aspects of estimation. A large proportion, if not the majority, of mutant genes fail to match up to 'textbook' genes-with faultless segregation ratios and expression-yet, these are the materials with which the practical researcher has to cope. For this reason, it is important to know how to deal with the assortment of genes which may display significant deviations from expectation. Part B examines the accumulated data on linkage for most of the laboratory mammals and provides a comprehensive and up-to-date survey. The need for a critical review has often been expressed and it is hoped that the present analysis will fill the gap. The volume of material is probably the most important in the animal kingdom other than that for Drosophila species. 340 pp. Englisch. …

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume serves as a general introduction to the state of the art of quantitatively characterizing chaotic and turbulent behavior. It is the outgrowth of an international workshop on 'Quantitative Measures of Dynamical Complexity and Chaos' held at Bryn Mawr College, June 22-24, 1989. The workshop was co-sponsored by the Naval Air Development Center in Warminster, PA and by the NATO Scientific Affairs Programme through its special program on Chaos and Complexity. Meetings on this subject have occurred regularly since the NATO workshop held in June 1983 at Haverford College only two kilometers distant from the site of this latest in the series. At that first meeting, organized by J. Gollub and H. Swinney, quantitative tests for nonlinear dynamics and chaotic behavior were debated and promoted [1). In the six years since, the methods for dimension, entropy and Lyapunov exponent calculations have been applied in many disciplines and the procedures have been refined. Since then it has been necessary to demonstrate quantitatively that a signal is chaotic rather than it being acceptable to observe that 'it looks chaotic'. Other related meetings have included the Pecos River Ranch meeting in September 1985 of G. Mayer Kress [2) and the reflective and forward looking gathering near Jerusalem organized by M. Shapiro and I. Procaccia in December 1986 [3). This meeting was proof that interest in measuring chaotic and turbulent signals is widespread. 488 pp. Englisch.…

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In the book are reported the main results presented at the Third International Workshop on Data Analysis in Astronomy, held at the EUore Majorana Center for Scientific Culture, Erice, Sicily, Italy, on June 20-27,1988. The Workshop was the natural evolution of the two previous ones. The main goal of the first edition (Erice 1984) was to start a scientific interaction between Astronomers and Computer Scientists. Aim of the second (Erice 1986) was to look at the progress in data analysis methods and dedicated hardware technology. Data analysis problems become harder whenever the data are poor in statistics or the signal is weak and embedded in structured background. Experiments collecting data of such a nature require new and non-standard methodologies. Possibilistic approaches could be merged with the statistical ones, in order to formalize all the knowledge used by the scientists to reach conclusions. Moreover, the last decade has been characterized by very fast developments of Intelligent Systems for data analysis (knowledge based systems, . ) that would be useful to support astronomers in complex decision making. For these reasons, the last edition of the workshop was intended to provide an overview on the state of the art in the data analysis methodologies and tools in the new frontieres of the astrophysics (y-astronomy, neutrino astronomy, gravitational waves, background radiation and extreme cosmic ray energy spectrum). The book is organized in two sections: - Data analysis methods and tools, - New frontieres in astronomy. 428 pp. Englisch.…

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume contains the texts of the nineteen lectures presented at the NATO-ASI - FEBS Course on 'DNA - ligand interactions: from drugs to proteins.' The Advanced Study Institute (ASIl was held from August 30th to September 11th. 1986 in the Abbey of Fontevraud (France). The ASI was attended by 112 participants from a wide scientific horizon and from twentyone different countries. It was in some way a follow-up of the ASI held in Maratea. Italy in May 1981 and which was published in the NATO ASI Life Science series as volume 45. While much has been learned about the way the cellular machinery maintains and transmits the genetic heritage. as well as how these processes are regulated. little is Known about how the interactions between the various partners involved are taKing place. The interactions of drugs and proteins with nucleic acids are of evident importance in the understanding of these problems. The spectacular advances in recombinant DNA technology and the increased sophistication of biophysical techniques. in particular :-ray diffraction and nuclear magnetic resonance. have created a scientific environment which is highly promising for the future of research in molecular biology. These advances permH the serious hope that biology on the molecular level may become a r-eality. Some of the contributions at the ASI presented the most recent advances in this e:citing field. 304 pp. Englisch.…

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The Advanced Study Institute (ASI) on Nonlinear Phenomena-in Physics and Biology was held at the Banff Centre, Banff, Alberta, Canada, from 17 - 29 August, 1980. The Institute was made possible through funding by the North Atlantic Treaty Organization (who sup plied the major portion of the financial aid), the National Research and Engineering Council of Canada, and Simon Fraser University. The availability of the Banff Centre was made possible through the co sponsorship (with NATO) of the ASI by the Canadian Association of Physicists. 12 invited lecturers and 82 other participants attended the Institute. Except for two lectures on nonlinear waves by Norman Zabusky, which were omitted because it was felt that they already had been exhaustively treated in the available literature, this volume contains the entire text of the invited lectures. In addition, short reports on some of the contributed talks have also been included. The rationale for the ASI and this resulting volume was that many of the hardest problems and most interesting phenomena being studied by scientists today ar.e nonlinear in nature. The nonlinear models involved often span several different disciplines, °a simple example being the Volterra-type model in population dynamics which has its analogue in nonlinear optics and plasma physics (the 3-wave problem), in the discussion of the social behavior of animals, and in biological competition and selection at the molecular level. 624 pp. Englisch.…

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -1. 1 Power-dissipation trends in CMOS circuits Shrinking device geometry, growing chip area and increased data-processing speed performance are technological trends in the integrated circuit industry to enlarge chip functionality. Already in 1965 Gordon Moore predicted that the total number of devices on a chip would double every year until the 1970s and every 24 months in the 1980s. This prediction is widely known as 'Moore's Law' and eventually culminated in the Semiconductor Industry Association (SIA) technology road map [1]. The SIA road map has been a guide for the in dustry leading them to continued wafer and die size growth, increased transistor density and operating frequencies, and defect density reduction. To mention a few numbers; the die size increased 7% per year, the smallest feature sizes decreased 30% and the operating frequencies doubled every two years. As a consequence of these trends both the number of transistors and the power dissi pation per unit area increase.In the near future the maximum power dissipation per unit area will be reached. Down-scaling of the supply voltage is not only the most effective way to reduce power dissipation in general it also is a necessary precondition to ensure device reliability by reducing electrical fields and device temperature, to prevent device degradation. A draw-back of this solution is an increased signal propa gation delay, which results in a lower data-processing speed performance. 172 pp. Englisch.…

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -These volumes contain the invited and contributed talks of the first general Conference of the Condensed Matter Division of the European Physical Society, which took place at the campus of the University of Antwerpen (Universitaire Instelling Antwerpen) from April 9 till 11, 1980. The invited talks give a broad perspective of the current state in Europe of research in condensed matter physics. New developments and advances in experiments as well as theory are reported for 28 topics. Some of these developments, such as the recent stabilization of mono-atomic hydrogen, with the challenging prospect of Bose condensation, can be considered as major break throughs in condensed matter physics. Of the 65 invited lecturers, 54 have submitted a manuscript. The remaining talks are published as abstracts. The contents of this first volume consists of 9 plenary papers. Among the topics treated in these papers are: - electronic structure computations of iron the density functional theory hydrogen in amorphous Si topologically disordered materials nuclear antiferromagnetism stabilization of mono-atomic hydrogen gas covalent and metallic glasses nonlinear excitations in ferroelectrics. 496 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -The fourth course of the International School of Physics of Exotic Atoms took place at the 'Ettore Majorana' Center for Scien tific Culture, Erice, from March 31 to April 6, 1984. As tradition, exotic atoms have been a tool for studying elec tromagnetic, weak and strong interactions at low energies. We felt it appropriate to have a full course devoted to a discussion of the information to be gained on the fundamental interactions from the study of low energy systems. In this kind of physics, which is characterized experimentally by very intense particle sources and very sensitive apparatuses, one can search for rare events and can perform precise measurements. Sensitive tests of the predictions of current theories of electro weak and strong interactions can thus be achieved. The course was attended by 54 participants from 23 institutes in 9 countries. The morning lectures reviewed the achievements of the field in the last few years and the afternoon seminars dealt with new results and projects. 516 pp. Englisch.…

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -During the last 30 years our knowledge and understanding of molecular processes has followed the development of increasingly sophisticated tech niques for studying fast reactions. Although the results are reported in papers and reviews, it is sometimes difficult for those not themselves active in these fields to find their way through the mass of published material. We hope that each book in this series will present a clear account of the present state of knowledge in a particular field of physical chemistry to research workers in related fields, to research students, and for the preparation of undergraduate and post-graduate lectures. Each chapter describes the theoretical develop ment of one area of study and the appropriate experimental techniques; the results presented are chosen to illustrate the theory rather than to attempt a comprehensive review. The first volume published in 1972 was concerned with the reactions of small molecules and free radicals in the gas phase. The development of flash photolysis in the 1950s paved the way by making it possible to generate free radicals in sufficient concentration for a spectroscopic' snapshot' to reveal their molecular structure. Their role in kinetic systems could then be followed directly, rather than be inferred from mechanism. The shock tube enabled gas mixtures to be heated to any desired temperature in a time which was shorter than subsequent chemical reactions. Discharge-flow methods enabled the reactions of atoms and free radicals to be studied directly. 296 pp. Englisch.…

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -With the development in recent years of NMR spectrometers capable of recording with a minimum of effort data that are both accurate and reproducible, a need has arisen for spectra catalogs and data books to aid the researcher. The ability to correlate a spectrum to a precalibrated chart accurately (to within 0. 02 ppm) has made chemical shift, along with the character of the spectral lines produced, an increasingly important tool in configurational analysis-a tool which this book is designed to complement. It is known that the chemical shift of a proton can be influenced by atoms as much as five or six carbons away, a fact of great importance to compound identification. The entries in this book, arranged according to proton environment, enable the researcher with a hypo thetical structure already proposed for his unknown quickly to locate examples of compounds having similar structures. An index of molecular formulas and a shift index, which should prove useful in hypothesizing alternate structures for the unknown and in checking out the hypotheses, have also been provided. The data collected represent some 4800 shifts from the spectra of about 1200 compounds that appear in the catalogs of Varian Associates, Sadtler Research Laboratories, and the American Petroleum Institute, whose cooperation is gratefully acknowledged. The alphanumerical code that is the basis of our presentation, and the explanation of its use, are borrowed intact from the NMR Spectra Catalog of Varian Associates, for whose permission to use this material we are especially grateful. 452 pp. Englisch.…

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Dr. V. V. Ol'shevskii is perhaps most familiar to Western readers as the author of 'Characteristics of Sea Reverberation,' published in translation by Consultants Bureau (New York, 1967). The present book, 'Statistical Methods in Sonar,' is, in part, a sequel to the first book, where now the author's stated purpose is 'to acquaint a broad range of specialists with the use of contemporary statistical methods for solving theoretical and applied sonar problems. ' As the author quite properly observes, the work is illustrative, devoted to a variety of relevant, specific technical problems from an analytical point of view, and is not in any way intended to be an all-inclusive treatise. Nevertheless, as the reader can verify subse quently, the author has succeeded in accomplishing his stated purpose. He has, moreover. provided us with a use ful and, in a number of instances, provocative work, which even five years after its original appearance retains its freshness and interest with material not to date covered in other books on the subject (for example, see Horton [~Q], Stephens [41] ). \* In this Foreword we first concisely review the author's material, on a chapter-by-chapter basis, after which a short general critique is given. Attention is called to various topics of particular interest to the professional audience. as well as to a number of highlights which deserve the reader's notice (a few additional comments on the technical editing are then included). 264 pp. Englisch. …

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -During October 18-31, 1980, the first course of the Inter national School of Pure and Applied Biostructure, a NATO Advanced Study Institute was held at the 'Et tore Majorana Center for Scien tific Culture' in Erice, Sicily, co-sponsored by national and international agencies. The subject of the course was 'Cell Growth', with participants (from 16 different countries) selected worldwide. The study of cell growth has been one of humanity's most challenging problems and it has been approached from many differ ent points of view, such as biochemistry, genetic engineering, cell biology, zoology, oncology, immunology, biophysics and a few other fields. It has been very difficult to keep such varied points of view all in one room and in one audience, because of the heterogeneity of background and inherent difficulty of communica tion, with occasional nominalistic rather than factual debates. This Institute aimed to bypass those limitations by approaching in a structured and tutorial fashion the problem of cell growth in three dimensions: (1) in terms of the various disciplines involv ed, from molecular to cellular biology, from genetic engineering to clinical oncology, from biophysics to immunology; (2) in terms of the system studied, from prokaryotes to eukaryotes and cancer cells; (3) in terms of the various levels of macromolecular orga nization, from membrane to cytoskeleton and chromatin. 840 pp. Englisch. …

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In alternating years, the Denver X-ray Conference turns its principal attention, through the choice of subjects for the plenary lectures, to various aspects of either X-ray fluorescence or dif fraction. This is a 'fluorescence' year, and the three invited lecturers are experts in techniques that are at, or perhaps yet a bit beyond, the forefront of our understanding and technology in that field. The common denominator in selecting these subjects was that each is approaching a full elucidation of theory, and active develop ment of practical hardware, and that each presents analytical pos sibilities which can hardly be ignored in the next generation of commercial instrumentation. In other words, these are techniques that many of us shall likely find ourselves using by the end of the decade. The greatest difficulty in selecting the subjects was the need to overlook others, particularly 1) the increasing inter est in 'in-situ' or on-line analytical control, for tagging, identi fication or sorting; and 2) the broad subject of the computeriza tion of instrumentation, with its powerful impact on the design of hardware, and its open invitation to the theorist to create more exact mathematical models of the analytical process, regardless of complexity, in the expectation that programmers will find ways to implement solutions in affordable, dedicated computers. 420 pp. Englisch. …

This item is printed on demand - it takes 3-4 days longer - Neuware -The impact of computers on all rea1ms of Chemistry has been one of the most important factors in the deve10pment of this science during the last years. In recognition of this fact, in 1971, the 'First International Conference on Computers in Chemi ca1 Research and Education' , was held at DeKa1b, I11inois, USA. A second Conference took p1ace in Ljub1jana, Yugos1avia in 1973 and this third Conference in Caracas, Venezuela, in 1976. The aim of these conferences was to provide a high level forum for the 1eading researchers to exchange information at the frontiers of present day computer app1ications to the different fie1ds of Chemistry. The present 'Third International Conference on Computers in Chemica1 Research, Education and Techno10gy', whose proceedings are pub1ished in the present vo1ume, was conceived, by means of aseries of invited 1ectures, as a survey of the present-date state of the art in some of the most relevant areas of computer app1ications in Chemistry. 492 pp. Englisch.…
