Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The systematic study of the adsorption of organic compounds on electrodes began with the comprehensive survey of adsorption on mercury carried out by Gouy in the first decade of this century. His studies with the capillary electrometer are still useful but do not lend themselves to detailed quantitative analysis. A more de tailed study of a few systems by Frumkin in his thesis (1919) led him to propose a quantitative phenomenological theory of organic adsorption (1925, 1926) at almost the same time as Stern proposed the model of the electrical double layer which remains the picture accepted in general terms today. The attempt at a molecular model made by Butler (1929) should be more satisfying but up to the pres ent the formidable difficulties of a molecular theory of interfacial phenomena have prevented the full interpretation of experimental results along these lines. In his work with Proskurnin (1935), Frumkin is also respon sible for the major experimental advance in the demonstration that reliable measurements of the capacity of an electrode-solution interface can be obtained provided that the work is carried out under conditions of scrupulous cleanliness. Even so, preCise mea surements of double layer capacities were not obtained until Grahame (1941) showed how convenient and reliable the dropping mercury electrode was the for these studies. This method and the hanging drop electrode remain the preferred methods for study of adsorp tion on mercury. Solid electrodes present a more difficult problem. 516 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -On May 14-16, 1982, a group of scientists met in Viareggio, Italy to present ideas, and exchange relevant data on current approaches on immunomodulators. We felt that the embodiment of the substance of that international symposium into this volume will be beneficial in keeping both clinicians and basic scientists abreast of the latest exciting developments in this rapidly accelerating field. We hope that the publication of this series of papers by an international panel of experts will enhance the nature of future inves t igat ive stud ies with such ent it ies . Under the rubric of immunology, it is obvious that such a term as 'immunomodulation' could be construed as being all encompassing. However, it is intriguing that the immune modulators touched on in these sessions can be subcategorized into about five broad groups. Almost all substances, excepting those entities that are immuno logically inert, will have some modulating effects on immunity. From the coarse adjustment of antibody feedback inhibition upon cellular limnunity to the subtle finesse envisioned in Jerne's idiotypic network and s'lppressor T cells, immunomodulators attempt to either magnify or diminish those responses that are normally elicited by antigen. The broad groups - thymic hormones, D.L.E., Interferon, drugs, and the use of bacterial products appear to be at the forefront of much of the pioneering work on immunomodulation. 472 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -He who knows and knows that he knows is wise; follow him. -ANCIENT PROVERB During a long career of public service as a government procurement and contracting official, I am still surprised to find big, successful corporations making the same mistakes that neophytes in government contracting mak~. And this is particularly true in the matter of writing proposals, which are the crucial element in most major procurement awards. It's true enough, as many suspect, that the big, well-known company has something of an edge over the smaller, lesser-known company com peting for any given government contract-psychologically, at least: The typical government executives, whether contracting officials or program managers, tend to have a bit more faith in the ability of the large company to carry out the program successfully. All things being equal, then, the big company is more likely to get the nod. However, because the large companies are well aware of that, many tend to become 'fat, dumb, and happy'-they try to coast or rest on their laurels. That is, they get careless about making a strong enough case for themselves in writing their proposals. And when they lose, often to smaller companies, they are both puzzled and outraged. They have for gotten that all government procurement is a competition-usually both technical and cost competition-and that the 'little guy' can win against the 'big guy,' if he tries hard enough. And especially if the bigger guy is a bit careless and does not put out his best effort. 308 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This volume contains the Proceedings of the NATO Advanced Research Workshop on 'Growth and Optical Properties of Wide Gap II-VI Low Dimensional Semiconductors', held from 2 - 6 August 1988 in Regensburg, Federal Republic of Germany, under the auspices of the NATO International Scientific Exchange Programme. Semiconducting compounds formed by combining an element from column II of the periodic table with an element from column VI (so called II-VI Semiconductors) have long promised many optoelectronic devices operating in the visible region of the spectrum. However, these materials have encountered numerous problems including: large number of defects and difficulties in obtaining p- and n-type doping. Advances in new methods of material preparation may hold the key to unlocking the unfulfilled promises. During the workshop a full session was taken up covering the prospects for wide-gap II-VI Semiconductor devices, particularly light emitting ones. The growth of bulk materials was reviewed with the view of considering II-VI substrates for the novel epitaxial techniques such as MOCVD, MBE, ALE, MOMBE and ALE-MBE. The controlled introduction of impurities during non-equilibrium growth to provide control of the doping type and conductivity was emphasized. 364 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Lewis Thomas has suggested that 'Perhaps the inflammatory reaction should be regarded as a defense of an individual against all the rest of nature, symbolizing his individuality and announcing his existence as an entity. ' Provision of these symbols and announcements is the task of various mediators of inflammation and this volume has been designed to present our current understanding of their biochemistry, cellular origins, pharmacology, and role in pathology. Unlike other volumes of collected papers, this book did not result from a specific conference or symposium at which each contributor presented his own, narrowly framed research experience. Rather, each of the chapters represents, in the form of a general review, a summary of our knowledge of the mediators and the mecha nisms by which they are released to launch the inflammatory response. Much effort has been taken to insure that the often conflicting terminology in this field is defmed in detail: many synonyms (e. g. , of the properdin system or the alternate pathway of complement activation) have been repeatedly presented, in order to avoid confusion. Although each of the contributors is actively engaged in the field of inflammation, few text figures or tables of ongoing research have been included; the overall aim was to provide a volume readily accessible to workers in other areas as well as to the general reader. 220 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume records the proceedings of, and the papers read at, an international conference to consider the use of electronic data processing methods in the major taxonomic plant collections of Europe, primarily herbaria but also living collections. This conference took place at the Royal Botanic Gardens, Kew, from 3rd to 6th October, 1973. It was attended by some 90 delegates, observers and speakers, mainly from a wide range of the major European herbaria, but also from other interested institutions. The problem to be discussed was a big one. Taxonomic collections of the sorts mentioned above constitute the main centres for the scientific documentation of the flora of the world. With the extinction of so many species more or less imminently threatened, and with the modification or disappearance of so many vegetation types through the activities of man, the information contained in these collections grows in importance. Their aggregate size, in Europe, has been estimated at between 50 and 100 millions, and these are annually augmented at a rapid rate. Each specimen or living plant comprises a source of evidence and information represented both by the specimen itself and the associated information provided by the collector and subsequent investigators - identifications, field notes, records of subsequent research, etc. This associated information is known as the label data. Research on the taxonomy and geographical distribution of plants usually requires data from specimens stored in a number of institutions in different countries. 228 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The study of the relationship between the structure, morphology and properties of polymer films has significantly progressed in recent years through the use of a number of phyiscal techniques - some new and some old. These methods include small and large angle x-ray diffraction, bire fringence, light scattering, infrared dichroism, fluorescence polarization, light and electron microscopy and interferrometry. This collection of papers, most of which were presented at a symposium at the Boston American Chemical Society Meeting in April, 1972, represent a collection of recent studies using many of these methods by some of the leading scientists in their fields. It is evident that these various techniques permit the study of various aspects of film structure such as crystal structure and orientation, amorphous orientation, the interrelation of crystalline and amorphous regions in lamellar, fibrillar, and spherulitic superstructure and the relationshi. p of these structural variables to the mechanical and optical properties of the films. Film structure is sufficiently complex that a complete understanding of the relationship between structure and properties will come from the employment of a combination of several of these methods. vii CONTENTS Optical Studies of the Morphology of Polymer Films 1 Richard S.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This century has witnessed the creation of new sciences extending the frontiers of knowledge to an unprecedented degree. We have seen the birth of cybernetics and bionics, bringing together such apparently distantly related branches of science as neurohistology and automation, synaptology and electronics. The electron microscope has resolved tissues almost down to the molecular level, and histochemistry has led to the fine analysis of brain structure. However, before these and other new sciences can develop properly and scientifically, a precise knowledge of the structure of the material with which they are concerned is absolutely essential. That is why the need exists at the present time for a detailed study of the larger units, i. e. , the neurons, their interrelationships and the pathways by which excitation is conducted. Biologists, neurologists, physicists, and specialists in other technical disci plines will find this study highly useful. During recent years many advances have been made in knowledge of the central visual system and its pathways. Above all, it has been found that the visual system is very extensive. The optic tract is connected, not only with the lateral geniculate body, but with the superior colliculus and the pulvinar. Besides the discovery of these principal pathways, connections have also been studied with the hypothalamus, the pretectal region, the medial geniculate body, subthalamus, and other parts of the brain stem. The visual system is thus connected with the reflex apparatus, the autonomic nervous system, and the auditory and reticular systems. 304 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This monograph is an attempt to present in a concise manner those aspects of the electrolytic growth of crystals considered to be of basic mechanistic significance. The accent has been put consistently on the understanding of the physical models of the processes discussed. Out of the extensive amount of information in this field, the authors have tried to abstract those systems which can be considered central, and which can, therefore, be related to the basic concepts connected with the electrodeposition of metals. In particular, stress has been laid upon consideration of atomic movements -of ions and molecules in solution, of adsorbed substances on the surface of metals, of steps on a growing crystal. Although the main stress is upon the physical picture, a number of derivations have been presented in detail. It is assumed that the reader is familiar to some degree with the concepts of electrodics; in particular, frequent reference is made to models of the electrical double layer at the metal solution interface and the transfer of charged species across it. 168 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The history of so-called storage diseases goes back to the end of the 19th and to the beginning of the 20th century when Fabry, Tay, Sachs, Gaucher, Niemann, Hunter, and Hurler first described the disorders which up to now are called by their eponym. The clinical descriptions soon were followed by pathologic studies, and within a short time ,the hereditary characters of these rare afflictions came to be recognized. Although sporadic reports during the early part of this century dealt with biochemical analysis of the 'stored' materials in these disorders, it was actually in the late 1930s that the abnormal deposits started to attract the increasing attention of chemists. S. H. Thannhauser brought the broad concept of lipidoses as a group of related disorders to the attention of the medical profession for the first time, and in 1939 Klenk observed that the brain of a patient with Tay-Sachs disease contained greatly increased amounts of a glycolipid for which he proposed the name 'ganglioside. ' 20 years has thrown new light on these afflic Work carried out in the past tions and has pinpointed the enzymatic and lipid abnormalities associated with the various 'storage' diseases. Moreover, electron microscopic studies have permitted detailed investigations of the fine structure of the various organs of afflicted patients. 296 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -It is unclear, and really no longer relevant, whether the information explosion that we now contend with has been fostered by the growth of specialization and subspecialization in medicine, or vice versa. What is clear is that the two are mutually supportive and constitute what would be in endocrine parlance a short-loop positive feedback system. As a result, for most areas of medicine, even the subspecialist in that area has a problem in maintaining currency, the more general specialist has substan tial difficulty in doing so, and the generalist is tempted to abandon the effort altogether. Nevertheless, for all, both the internal pressures of conscience and self-esteem and the external pressures generated by peer review, recertifi cation, and subspecialty boards create the need for continuous self-educa tion. We are, therefore, in an era in which the means of dissemination of new information deserves as much creative attention as does its acquisition. 348 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -For my past sins, Leslie Ettre has given me the privilege of writing a few words to preface his excellent little book. It gives me great pleasure to do so, because of the many years of fruitful collabo ration we have had at Perkin-Elmer, because it is refreshing to see a treatise in gas chromatography in which the theoretical treatment has been bared to its essentials, without a mushrooming of formulae which, by means of an ever increasing number of parameters, account for more and more, and explain less and less, and because the author has recognized that the gas chromatographic column is a nearly passive element in its own right which deserves to have a treatise written nearly exclusively about it, just as electrical circuit theory can be discussed without elaborate references to vacuum tubes and meters. I wish this conscientiously written volume the success it deserves. M. J. E. GOLAY VII Preface Gas chromatography is a separation technique used primarily in analytical chemistry. Therefore, it is evident that special emphasis should be placed on that particular part of the apparatus in which the separation takes place. This part is the column, the heart of the gas chromatograph. The goal of researchers in the field of gas chromatography has been-from the beginning-to understand the separation process so that they might design columns with the best possible performance. Such investigation led M. J. E. 188 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -According to the classical concept of Geoffrey Harris the pituitary gland is controlled by the brain by means of blood-borne chemical messengers produced by central neurons. The recent isolation and structural characterization of several such messengers by Roger Guillemin and Andrew Schally and their collaborators brought the final proof for this hypothesis. This also meant that the extensive knowledge collected in the field of neurobiology now became highly relevant for the endocrinologists. For this reason it was felt important to organize a symposium which brought together experts in the fields of neurobiology and endocrinology. The idea was to focus the attention on neuronal mechanisms, particularly those related to chemical transmission, which may be of importance for the central regulation of hormonal secretion patterns. We would like to express our sincere gratitude to the Nobel Founda tion for supporting the organization of the Nobel Symposium 42 on 'Principles of the Central Regulation of the Endocrine System'. We would also like to express our thanks to all participants, to Professor Carl-Gustaf Bernhard, Permanent Secretary of the Royal Academy of Sciences, for making the facilities of the Academ- available to us, and to the Symposium secretaries Mrs. Gun Hultgren, Mrs. Lena Persson and Mrs. Ulla-Britt Wedin. It is a pleasure to acknowledge the generous financial support from the Nobel Foundation and its Nobel Symposium Committee through grants from the Tercentenary Foundation of the Bank of Sweden, and from the Swedish Medical Research Council, KABI AB, Stockholm, and ASTRA AB, Sodertalje. 572 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The purpose of this book is to interpret more sensitively some of the offerings of the standard text book of general chemistry. As a supplement thereto, it covers various aspects of formulation and stoichiometry that are frequently treated far too perfunctorily or, in many instances, are not considered at all. The inadequate attention often accorded by the comprehensive text to many topics within its proper purview arises, understandably enough, from the numerous broad and highly varied objectives set for the first year of the curriculum for modern chemistry in colleges and universities. For the serious student this means, more often than not, the frustrations of questions unanswered. The amplification that this book proffers in the immediate area of its subject covers the equations representing internal redox reactions, not only of the simple but, also, of the multiple disproportionations of which the complexities often discourage an undertaking despite the challenge they offer: distinctions to be observed in the balancing of equations in con trasting alkali-basic and ammonia-basic reaction media; quantitative contributions made by the ionization or dissociation effects of electrolytes to the colligative properties of their solutions; intensive application of the universal reaction principle of chemical equivalence to the stoichiometry of oxidation and reduction. 236 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This book is the product of the Conference on Nutrition and Human Reproduction, supported and organized by the National Insti tutes of Child Health and Human Development, and held at the National Institutes of Health, Bethesda, Maryland, in February 1977. The genesis of this Conference came from the work of the Subcommittee on Nutrition and Fertility of the Committee on International Nutrition Programs of the National Research Council. The purpose of the Conference was to assemble scientists and program planners from a broad range of fields including nutrition, epidemiology, demography, endocrinology, sociology, economics, anthropology, biostatistics and public health. Each individual brought his or her analytical skills and perspective to the meeting, with the goal of developing a more coherent picture of the many facets of nutrition and reproduction. The approach was to get a more comprehensive view by: 1. Clarifying terminology and definitions. 2. Reviewing recent and current work on the biological basis for nutrition-fertility interactions. 3. Reviewing biomedical and socioeconomic factors related to breast-feeding to assess how this practice relates to maternal and infant nutrition and fertility. 4. Assessing some current analytical models for defining nutrition-fertility interrelationships. 5. Reviewing recent field studies from Africa, Asia and Latin America which are examining the interrelationships of nutrition and reproduction. 528 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The articles which make up this book were all expressly written to honor a remarkable man and a remarkable psychologist, Joseph McVicker Hunt, on the occasion of his 70th birthday. The contributors to this volume, with the exception of Hunt's teacher, J. P. Guilford, are students and colleagues of Hunt's whose intellectual and professional paths have crossed his in some significant way. In terms of content, the contributions collectively range across many of the conventional boundaries that demarcate the territories into which psy chological subject-matter has been divided. In so doing, they remain faithful to the man they honor, for whom such boundaries have had, at best, only provisional reality. Yet as the introductory chapter attempts to make clear, there is a unifying theme that lies behind the apparent diversity of Hunt's work. While we wished to mark Hunt's specific contributions to the diverse areas represented in this book, we also hoped to capture the unity of viewpoint that ties them together. 464 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -My favourite literary critique comes from the little girl in James Thurber's The Darlings at the Top oj the Stairs: 'This book tells me more about penguins than I wanted to know'. My daughter Clio, who learned the alphabet by typing words for the first draft of this book, has similar sentiments about the present work, and she suggests that my next effort 'should be quite short, maybe four pages'. However, this is an epistemological work, in a very general sense. It deals not only with the 'facts' of evolutionary biology and its interpretive logic, but also considers intellectual progress and prejudice, soul-searching and gullibility, and heuristic induction and wishful thinking; which may be more about penguins than students accustomed to cut-and-dried assertions, and teachers who cut and dry, might want to know. Some of my penguins, progenitors of significant epistemological lines, have been detailed down to the last feather, including a number of birds that by conventional wisdom, 'nobody takes seriously'. Some are sketches copied from other naturalists; others are phantoms that cry out for an incarnation denieci by a combination of accident and time constraints. Students in my courses in comparative physiology and the history and philosophy of biology have been the main sounding boards for my ideas. Richard Ring has always listened with polite interest when I have expatiated. 416 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Differential psychology, or the psychology of individual differences as it is better known, is perhaps the single most important basic psychological science that underlies professional practice in psychology. The recent age of behaviorism all but ignored individual differences, but in this decade the study has emerged from relative dormancy with a new vitality, fueled by new concepts, technologies, statistics, and new viewpoints on old ideas that are moving us forward. This work is intended to be a review of as well as a primer on many of these advances and new approaches to the study of individual differences. The venerable, interesting, and often controversial Eysenck opens the volume with a review of recent results and new techniques for unlocking the physiological basis of what is commonly understood to be intelligence. Eysenck and his students, in his London laboratory, have been fostering advances in this field for more than four decades. Their latest work could be the most exciting of Eysenck's illustrious, scholarly career. Eysenck's eye-opening, innovative work on the relationship between evoked potentials and performance on traditional psychometric measures, presented with a new slant, is certain to attract much attention in coming years. Eysenck and Barrett's chapter is followed by a closely related work by Arthur Jensen, who gives us a revitalizing look at the concepts of Sir Francis Galton, the founder of the psychology of individual differences. 496 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The finite element method (FEM) has been understood, at least in principle, for more than 50 years. The integral formulation on which it is based has been known for a longer time (thanks to the work of Galerkin, Ritz, Courant and Hilbert,1,4 to mention the most important). However, the method could not be applied in a practical way since it involved the solution of a large number of linear or non-linear algebraic equations. Today it is quite common, with the aid of computers, to solve non-linear algebraic problems of several thousand equations. The necessary numerical methods and programming techniques are now an integral part of the teaching curriculum in most engineering schools. Mechanical engineers, confronted with very complicated structural problems, were the first to take advantage of advanced computational methods and high level languages (FORTRAN) to transform the mechanical models into algebraic equations (1956). In recent times (1960), the FEM has been studied by applied mathematicians and, having received rigorous treatment, has become a part of the more general study of partial differential equations, gradually replacing the finite difference method which had been considered the universal tool to solve these types of problems. 208 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The present volume is based on the proceedings of the 12th Workshop of the INFN ELOISATRON Project, held at the 'Ettore Majorana' Centre for Scientific Culture (EMCSC), Erice (frapani), Sicily, Italy, in the period September 15-20, 1990. The proceedings deal with the presentation of 'New Technologies for Supercolliders'. Three new energy frontiers (16,40 and 200 TeV) are now opened up for the future of Subnuclear Physics. Basic problems above the Fermi-energy are crowding up: but no one knows the energy levels needed for their solution. This is why the technology for experiments with the new generation of Supercolliders needs to be pursued having in mind the problems which are of common interest in the three energy frontiers. The primary purpose of the Workshop was to contribute towards the highest energy limit in the search for new instruments and new technologies. Furthermore, the present status and performances of various detector technologies were reviewed. The possible options for a powerful apparatus whose goal would be the discovery of the top, Higgs and SUSY particles in a very high energy, high rate environment, were finally analysed. The Workshop was sponsored by the Italian National Institute for Nuclear Physics (INFN), the Italian Ministry of Education, the Italian Ministry of Scientific and Technological Research and the Sicilian Regional Government. We are thankful to the staff of EMCSC for their efficient and warm support. 404 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The development of the modern organic insecticides has contri buted a major chapter to the history of neurotoxicants. From their roots in the organochlorines and organophosphates discovered prior to and during the Second World War, to the carbamates developed in the 1950's, and most recently to the extremely potent and promising synthetic pyrethroids, the most important organic insecticides have been those whose wite of action lies within the nervous system. In this regard, man is only mimicking nature in attacking the nervous system with lethal intent since potent neurotoxins are cornmon compo nents of the venoms with which animals of all types defend themselves and subdue their prey. This central role of the nervous sytem as a broad target for pesticides may also be projected into the future - a prediction to which this volume is devoted. The nervous system in its diversity is likely to be of central concern to those charged with discovering novel pesticides whether they be modifications of familiar chemical groups or structurally novel neurotoxicants such as the nitromethyl ene insecticides described here. On a second front, the ability to influence insect behavior through the nervous system will become increasingly important in pest management. Pheromones represent one obvious example of this; recent work described in this volume indi cates that the forrnamidine pesticides may represent another. 300 pp. Englisch.

During the past decade computational science has developed itself to a third methodology besides the experimental and theoretical sciences. This remarkable evolution was only possible due to a drastic increase of the computational power of present day computers. Indeed, computational physics and chemistry as such is certainly not new, but it was only during the past ten years or so that realistic problems could be solved numerically to a sufficient degree of accuracy. During this workshop the state-of-the-art in high speed computation was presented by a team of lecturers who are well known for their competence in this field. It is a pleasure to thank several organizations and companies who made this workshop possible. First of all, the main sponsors: the Belgian National Science Found ation (NFWO-FNRS) and the 'Universitaire Instelling Ant werpen'. Next, the co-sponsors: Agfa-Gevaert N.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Forensic toxicology has progressed rapidly and diversified greatly in recent years. The members of the International Association of Forensic Toxicologists provide a valuable service through the association's bulletin. In its pages members hear of new poisons as they are encountered and the analytical techniques used to deal with them. There is a wealth of information in the form of case reports which is used to assist with the interpretation of the results. Each year the members have the opportunity of meeting in Europe. In 1979 the chosen venue was the University of Glasgow and the meeting was hosted by the Department of Forensic Medicine and Science. The department was established by Royal Charter in 1839 within a few years of the beginning of the modern approach to toxicology. In those early years the function of the department was to teach forensic medicine and toxicology. Today the department has become a recognised centre for the teaching of forensic medicine. The toxicology section has expanded greatly to provide the best forensic and environmental toxicology in Scotland. Inorganic analytical facilities are available for the investigation of metallic poisons by atomic absorption spectrometry, neutron activation analysis, X-ray fluorescence and anodic stripping voltametry. Organic analytical toxicology is pursued using gas chromatography, high performance liquid chromatography, immunoassays, and gas chromatography mass spectrometry. Apart from the normal research and routine investigations of a toxicological laboratory the department specialises in the investigation of fire related deaths, solvent abuse (glue sniffing) and trace element studies in human subjects. 324 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Dr. Hueck explains in the 'History and Development of the NATO Advanced Research Workshop' some ideas on the genesis of the Workshop. The reader should understand that this volume is a preliminary analysis of a problem that has not received much attention. The case histories, for example, are illustrative because one volume cannot include all histories, or even those in Europe. Consequently, case histories are lacking on many parts of the world, including central Europe and North America, not because these are unimportant or less disastrous ecologically than the case histories covered, but because selecting only a few illustrative cases was possible. The geographic and ecological coverage was originally much broader, but, unfortunately, some participants were unable to attend and this resulted in an even more skewed distribution geographically. However, participants generally agreed that the information necessary to analyze the problem was covered in sufficient depth by those in attendance and that other case histories would have been interesting, but would probably not have caused substantive changes in the conclusions or recommendations. The Workshop organizers did not selectively choose people, companies, or countries to the exclusion of others. The committee selected a broad array of people, countries, and industries, and the participants were those able to corne, prepare a manuscript, and meet the other conditions. Thus, what appears to be a skewed distribution was not planned as such, but was the consequence of people being unable to attend for various reasons. 176 pp. Englisch.

Its authors have been courageous in bringing together in one text a triad of topics that cover such large tracts of biomedical sciences as epidemiology, biochemistry, immunology, and clinical medicine. Malnutrition and infection are known to be closely linked, the one promoting the other. The adaptive immune system forms a part of the link since it is responsible for a good deal of defense against infection, and it may be affected adversely by malnutrition and indeed by infection itself. Knowledge in this complex field is of great potential importance because malnutri tion and infection are such dominant features of the ill-health of many of the world's underprivileged people. As this book shows, there is no lack of technical facets for study. There are now so many components of the immune response which can be measured or assessed and so many aspects of nutritional biochemistry which can be studied that the problem is to select what to study and where to begin. Moreover, the great number of variables in the nature of nutritional deficiencies, in types of infections or multiple infections and in the genetic, environmental, and social background of the affected people, all combine to make interpretation and application of findings a speculative business. Descriptions of cause and effect must us ually be provisional rather than definitive. 268 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The thalidomide tragedy which occurred slightly more than a decade ago made public officials and the general public acutely aware of the teratogenic potential of drugs. Although specialists in pharmacology and developmental biology had been studying this problem many years before, this catastrophic episode triggered the passage of legislation which required that information about the teratogenicity of drugs be produced before the drugs could be available to the general public. Gross deformities in man produced by drugs are frequently difficult to reproduce in experimental animals and the changes which are produced in other animals are frequently not translatable to humans. The problem of evaluating the potential that drugs have to produce gross malformations is small, however, compared to the evaluation of subtle but permanent behavioral effects which drugs may exert upon the developing organism. Nevertheless, many experimental studies in recent years indicate that subtle biochemical changes produced by drugs on brain tissue during critical periods of fetal or early post natal maturation may become manifest subsequently as behavioral deviations in early childhood or adolescence. Hyperkinetic disorders, epilepsies and other developmental disabilities may have a subtle biochemical imbalance, perhaps drug induced, as an underlying factor. This symposium was organized with the intent of bringing to gether prominent investigators who are working in different aspects of brain development and who are interested in the effects of drugs on the developing brain in order to discuss their findings, pro pose new theories, and open new avenues for future research. 552 pp. Englisch.

The significance of this theory is beginning to have an impact particu larly with respect to the design and implementation of the relational model of data bases. To further the state of the art in the theory of data bases, a workshop was held in TOulouse, France on December 12-14, 1979. The workshop was a sequel to one held two years previously and entitled, 'Logic and Data Base Workshop'. As with the earlier work shop, the meetings were conducted at the centre d'Etudes et de Recherches de l'Ecole Nationale Superieure de l'Aeronautique et de l'Espace de Toulouse (C.E.R.T). We are pleased to acknowledge the financial support received from the Direction des Recherches, Etudes et Techniques d'Armement (D.R.E.T.), and from C.E.R.T. that made the workshop possible. 444 pp. Englisch.

Also illustrative of this method is a contribution on microencapsulated pesticides by C. B. Desavigny and E. E. Ivy of Pennwalt Corporation. Another method of polymerization in situ is micro encapsulation by vapor deposition, the subject of W. M. Jayne of Union Carbide Corporation. The more mechanical methods of microencapsulation are represented by two techniques, one involving a fluidized bed the other involving mainly a centrifugal method. The fluidized bed method is covered in a paper by H. Hall and T. M. Hinkes of the Wisconsin Alumini Research Foundation. The centrifugal and other related methods are treated by Mr. J. E. Goodwin and Mr. Sommerville of the Southwest Research Institute of San Antoni~ Texas. Dr. G. Baxter of Moore Business Forms, studied capsules made by mechanical methods as well as by chemical methods. Mr. Russell G. Arnold of the Bureau of Veteranary Medicine of the Food and Drug Administration draws our attention to the procedures to be used for securing approval of a new animal drug application for the marketing of microencapsulated products. And last but not least, we have a contribution by Mr. G. O. Fanger on 'Micro encapsulation a Brief History and Introduction, whose title speaks for itself. 192 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Information systems science is advancing in many directions with rapid strides. Many diversified ideas, methodologies, and techniques have been conceived and developed for improving the design of information systems and for inventing new methods for solving complex information problems. This volume, the seventh of a continuing series on information systems science, covers five timely topics which are in the mainstream of current interest in this growing field. In each chapter, an attempt is made to famil iarize the reader with some basic background information on the advances discussed, so that this volume may be used independently or in conjunction with the previous volumes. The emphasis in this volume is centered upon diagnosis for digital systems, distributed information networks, micro computer technology, and data structures for pattern recognition. In recent years, digital systems have found widespread applications in on-line real-time processing. Such applications demand high reliability, availability, and serviceability. Reliability may be improved through the use of highly reliable parts. Improvement in integrity may be accompanied by retry operation and redundant configuration. Serviceability may be improved by making use of fault diagnosis techniques. Chapter 1 is devoted to this important subject. Fault diagnosis techniques are developed to improve serviceability and to shorten mean time for repair. Kitamura, Tashiro, and Inagaki discuss many recent methods for fault diagnosis and explain them with illustrative examples. 328 pp. Englisch.
