Chapter 6, Arenaviruses: The biochemical and physical properties have now been clar ified, and they show a remarkable uniformity in the various viruses constituting the group. The possibility that prenatal infection with LCM may result in hydrocephalus and chorioretinitis has been raised. Serologic surveys have suggested the existence of Lassa virus infection in Guinea, Central African Empire, Mali, Senegal, Cameroon, and Benin, in addition to earlier identification in Nigeria, Liberia, and Sierra Leone. Chapter 7, Coronaviruses: New studies have confirmed the important role of these viruses in common respiratory illnesses of children and adults. The viruses are now known to contain a single positive strand of RNA. About 50% of corona virus infections result in clinical illness. About 5% of common colds are caused by strain DC 43 in winter.

Taschenbuch. Zustand: Neu. Neuware - At the turn of the century gynecology had achieved independence from surgery in most medical schools; although gynecologists were surgeons, their interests were turning toward nonsurgical aspects of their specialty. In 1900, merely two years after the Curies' discovery, radium was first used as a treatment for carcinoma of the cervix. In that day cervical cancer claimed more women's lives than any other malignancy and was described by Wil liam P. Graves, the second professor of gynecology at Harvard as follows: 'Cancer of the cervix may rightly be termed of all tumors one of the most deadly and most ghastly. It kills by slow torture, causing in later stages months of agonizing pain and producing a discharge of such a foul and nauseating character as to repel proper medical assistance. Nurses declined to care for these cases, while many public hospitals closed their wards to them as patients. ' In late twentieth century parlance the dramatic results of radium therapy would indeed have been called a 'breakthrough' and radium techniques, later combined with external irradiation, were devel oped by gynecologists, no longer just surgeons. Pathology was the basic science of gynecology and gynecologists with a special interest in pathology served as pathologist to the departments of gynecology. As late as 1970 six months of the three-year residency program in obstetrics and gynecology at Harvard were devoted to formal training in pathology. …

Taschenbuch. Zustand: Neu. Neuware - In addition to performing its prime function as a vehicle for scientific communications of varied colora tions, Molecular and Cellular Biochemistry is again focusing on two subjects which it treats in depth. One of these is a book issue dealing with the transglutaminase reaction. The other is this issue that deals with induction and modulation of enzymes. This is a very broad subject that calls for broader coverage than could be included in one book issue. However, I have elected to include only certain contributions that serve as general examples of the principles involved. There are six articles on enzyme regulation in hepatocyte culture. These include arginase and argino-succi nate synthetase, y-glutamyl transferase and plasminogen activitor. Other regulatory enzymes that are discussed are protein kinases, 2,3-bisphosphoglycerate synthetases, carbamoyl phosphate synthetase, heme oxygenase, cytochrome P-450, tyrosine hydroxylase, fatty acid synthetase, acetyl eoA carboxylase, among others. Also included is the regulation of several enzyme messengers RNAs. As in the past, subscribers to the journal will receive this double volume as a continuation of regular issues of the journal Molecular and Cellular Biochemistry. This double volume will also be available separately in the form of a book issue to interested readers through Martinus Nijhoff Publishers. v.A.

This item is printed on demand - it takes 3-4 days longer - Neuware -This volume summarises the lecture and poster sessions of a NATO advanced workshop held in Edinburgh, July 15th-19th, 1985. The workshop was held to bring together plant scientists of many different disciplines but who share a common interest in the regulatory role of calcium in plant development. Although this volume covers the formal proceedings, an equal length of time was devoted to discussion both in large and small groups. A little of the flavour of the directions and character of the discussions will be found in the final article by David Clarkson which was written to cover this other wise uncovered area of the workshop. The volume reflects much of the current excitement in the field of plant calcium research. Many of the participants are pioneers in their res pective areas and the extent to which the last five years has seen a drama tic unfolding, a complete inversion of the role of calcium from simple macro nutrient to major metabolic and developmental controller is recounted here. The material is new and much of it unpublished. In plant physiology, the eighties may yet be designated the decade of calcium. 472 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -As is often the case, the preface is the last task to be finished during the preparation of a large volume such as you are now holding. The first task, obtaining approval for a symposium on the industrial applications, now seems a long time ago. The idea orginated with John Stevens, probably in 1982, from his observation of papers dealing with industrial applications of the Mossbauer effect appearing in the Mossbauer Effect Reference and Data Journal. His initial suggestion for a symposium entitled 'Industrial Applications of the Mossbauer Effect' to be held at a national meeting of the American Chemical Society eventually led to the symposium at the International Chemical Congress of Pacific Basin Societies which met in Honolulu, Hawaii in December 1984. This volume is the result of the symposium at the above mentioned Congress, but is not actually the 'proceedings' of the symposium because this volume does not contain all of the over one hundred Mossbauer effect papers that were pre sented at the symposium. Rather it contains a selection of papers that the or ganizing committee for the symposium deemed most appropriate for a volume devoted to industrial applications of the Mossbauer effect. The final volume also contains six chapters that were not a part of the symposium but which are closely related to the topic. There is another difference from many proceedings. 808 pp. Englisch.…

Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A lithium-drifted germanium detector is a semiconductor de vice which operates at liquid nitrogen temperature, and is used for detection of nuclear radiation, mostly gamma ray. The detection occurs when the y-ray undergoes an interaction in the intrinsic or I region of the semiconductor. The interaction results in the pro duction of charge carriers which are swept out by an electric field. This is accomplished by reverse biasing the detector with approxi mately 100 v/mm of intrinsic material. The total amount of charge swept out is proportional to the energy dissipated in the intrinsic region. This may include the total energy of the photon, but gen erally somewhat less. The Ge(Li) device is a semiconductor p-n device with a very large intrinsic region between the positive carrier region and the negative carrier region (P-I-N). The fabrication of this device consists of three major steps: the diffusion of the lithium into the p-type germanium to give an n-type surface region, the drifting process to obtain the intrinsic region as deeply as possible, and the surface preparation. There are numerous procedures for the various steps as well as criteria for material selection and the preparation of the materials. 228 pp. Englisch.…

Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Until recently, understanding of the lymphomas was limited and largely descriptive. Attention has been focused, for the most part, upon morphological issues and clinical matters. Although useful, this approach has many shortcomings. The true cytoidentity of primary neoplastic cells was not established by these methods, nor could their clonal nature be recognized. The more overt changes in immunological function, such as monoclonal gammopathies and immunodeficiencies, were appre ciated as important components of these diseases. However, subtle immunological perturbations were not recognized. Furthermore, associations were not established between the lymphoreticular neoplasms on the one hand and both primary and secondary immunological abnormalities on the other. There has been considerable recent progress in the fields of immunobiology, cytology, and immunochemistry. These new approaches have proved readily applicable to studies on the lymphomas. The term 'lymphoma' has been applied to a heterogeneous group of neo plasms that involve lymphoid tissues. This term is not altogether satisfactory, since it implies that cells of primarily the lymphoid series are involved in the neoplastic process. Some neoplasms, heretofore classified as 'lymphomas,' now appear, from the results of penetrating analysis using newer methodology, to be malignan cies of the macrophage series, rather than of the lymphocytic series. These neo plasms include Hodgkin's disease and a minority of neoplasms previously referred to as 'histiocytic' lymphomas. The majority of these 'histiocytic' lymphomas are now known to be lymphoid malignancies involving the B-cell series. 784 pp. Englisch.…

Evidence is available that intercellular channels are essential for electrical synchronization in excitable tissues and for the diffusion of molecules from cell to cell. This process of cell-to-cell communication is so reliable that it was pre served throughout the evolutionary scale. As evolution generates diversity it is not surprising that gap junctions are not the same in all systems. It is known, for 2 instance, that junctional permeability is reduced by high free [Ca +]j in some cells or by a fall in pHi in others, or enhanced by cAMP. Our knowledge of the physiological modulators of junctional permeability is still scanty. Moreover, the compartmentalization of the intracellular milieu represents an additional complication in the interpretation of many studies of cell-to-cell communication. The present volume represents an effort to provide the reader with an actualized view of the mechanisms of cell communication and of the physiologi cal and pathological implications of junctional and nonjunctional communica tion. Let us hope that the content of this book helps future studies in establishing a better picture of the cellular and molecular mechanisms involved in the process of intercellular communication. 392 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -The management of Alzheimer's Disease and the related dementias is one of the major challenges to health care professionals and American society-at-large for the coming decade and the coming millennium. The rapid growth of the over-eighty-five population, the group which, as recent studies have confirmed and as many of us clinicians have long suspected, has an even higher prevalence than previously quoted of dementing disorders, is the major cause of this. We are thus challenged by, as Bernard Issacs used to call it, 'the survival of the unfittest,' as well as the oPtimistic approach of 'bringing life to years,' as John F. Kennedy said. The fact is that we, as a society, tend to confuse 'treatment' and 'cure' (and 'prevention'). As the proceedings of the conference which this book represents emphasize, there is considerable work going on about the potential prevention of, or at least the reduction of, symptomatology in these illnesses by interventions genetically, chemIcally, and so forth. However, the more we find out, the more complicated it becomes, and the more heterogeneous Alzheimer's and the related disorders appear to be, not only in their manifestations (as clinicians have long recognized) but also in the individual initiating and underlying processes. For these reasons, absolute preventive techniques or the likelihood of an intervention which will reverse the process in a high proportion of patients, do not appear to be just around the corner. 176 pp. Englisch. …

Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The papers in this volume were presented at an international symposium on Topics in Surface Chemistry which was held in Bad Neuenahr, West Germany., September 7-9, 1977. The symposium was sponsored by IBM Germany. It has been recognized for many years that our understanding of bulk phenomena and their subsequent exploitation depends largely on our ability to define correlations between microscopic structure and the physical and chemical phenomena of interest. The role played by surface phenomena in the overall behavior of a material has been a subject for speculation for a long time, but only during the last decade or so have experimental and theor etical tools been developed which make it possible to investigate surface structure and related surface phenomena uniquely. Numerous surface spectroscopies have been developed in recent years intended to describe the geometric, vibrational and electronic structure of a surface. Our present understanding of surface, thin film and interfacial phenomena in solid state physics owes much to these developments. In chemistry much of the interest in surface science has come from the obvious implications to such important and diverse fields as catalysis and corrosion. It takes little imagination to recognize that there are many other areas where advances in surface science can be brought to bear. 420 pp. Englisch.…

Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book contains the lectures of the second course devoted to bioelectro chemistry, held within the framework of the International School of Biophysics. In this course another very large field of bioelectrochemistry, i. e. the field of Membrane Phenomena, was considered, which itself consists of several different, but yet related subfields. Here again, it can be easily stated that it is impossible to give a complete and detailed picture of all membrane phenomena of biological interest in a short course of about one and half week. Therefore the same philosophy, as the one of the first course, was followed, to select a series of lectures at postgraduate level, giving a synthesis of several membrane phenomena chosen among the most'important ones. These lectures should show the large variety of membrane-regulated events occurring in living bodies, and serve as sound interdisciplinary basis to start a special ized study of biological phenomena, for which the investigation using the dual approach, physico-chemical and biological, is unavoidable. Since, as already mentioned, it was impossible to exhaust, even roughly, is a short course like this, the presentation and introductory treatment of the extremely large variety of membrane phenomena, it can be expected that the third course will continue the subject of membrane phenomena deepening some ones presented in this course and introducing some new ones. vii CONTENTS Symbols and acronyms IX Opening address G.

Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume contains papers associated with the conference 'Atomic Spectra and Collisions in External Fields II', that took place July 30-31 1987 at Royal Holloway and Beford New College. The first meeting of this name was held at the National Bureau of Standards in Gaithersburg, Maryland in 1984, and, if any tradition can yet be said to have been established in the series, it is that the proceedings be written after the conference. We hope thereby to preserve some impression of the discussions that took place, which in both cases were vigorous and unihibited. Both meetings happen to have convened in proximity to major developments in the field. At the time of the first conference, results of experimental measurements of dielectronic recombination in electron ion beams were beginning to appear. These showed large discrepancies with theoretical calculations, which were attributed to the effects of rather weak electric fields on the highly-excited states that mediate the recombination process. This conjecture gave rise to widespread concern in the plasma physics community that the representation of dielectronic recombination in existing plasma models, in which it plays an important role in energy and ionization balance, might be seriously in error due to neglect of the effects of electric and magnetic fields. The subject of field effects on recombination processes was thus a major focus of the 1984 meeting. 472 pp. Englisch.…

Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume contains the proceedings of a conference held in Freiburg, West Germany, September 22-25, 1980, entitled 'Manned Systems Design, New Methods and Equipment'. The conference was sponsored by the Special Programme Panel on Human Factors of the Scientific Affairs Division of NATO, and supported by Panel VIII, AC/243, on 'Human and Biomedical Sciences'. Their sponsorship and support are gratefully acknowledged. The contributions in the book are grouped according to the main themes of the conference with special emphasis on analytical approaches, measurement of performance, and simulator design and evaluat ion. The design of manned systems covers many and highly diversified areas. Therefore, a conference under the general title of 'Manned Systems Design' is rather ambitious in itself. However, scientists and engineers engaged in the design of manned systems very often are confronted with problems that can be solved only by having several disciplines working together. So it was felt that knowledge about newly developed methods and equipment, applicable in the design process, is of common and increasing interest for all those who are engaged in the design of manned systems, from the earliest con ceptual design phases until operation under real circumstances. This seems to be particularly true in view of restricted resources of manpower and energy. 500 pp. Englisch.…

Upatnieks on the subject of holography appeared in 1961, there has been a virtual explosion of research activity in the field. More than 500 papers and articles on holo graphy have appeared in the last ten years. Many applications of holo graphy have been proposed, and some of these are beginning to enter the realm of usefulness. One of the applications that appears to hold great promise is acoustic imaging by means of holography. The first papers on this subject appeared in 1966, but already research activity in the field is burgeoning. Three symposia wholly devoted to acoustical holography have been held and the papers published in book form. The purposeof this book is to bring together the results of research in acoustical holography, some of it as yet unpublished, under one cover so that workers in holography, nondestructive testing, medical imaging, underwater imaging, and seismic exploration can decide whether this new technique can be useful to them. 240 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -It has been nearly 35 years since the peacetime Biology Division of Oak Ridge National Laboratory was started, born of rather inauspicious conditions. Virtually no facilities were available and most of the wartime scientists had left. So, when we started out, it was obvious to me that something had to be done to reestab lish research. Even more, because Oak Ridge was not known at that time for its biological work but rather for the separation of Uranium 235, nuclear reactor development, and radioisotope produc tion, a new tradition had to be promoted. Although good biological work had been done at Oak Ridge during the war to protect the workers and the results of this work were quite excellent, very few installations remained. When we started the work of the Biology Division, it became essential to make it part of the flow of mod~rn biology allover the world. As Director, I had to do more than just attract promising scientists. We created an atmosphere conducive to creative research and nurtured all of the other aspects of a productive laboratory. Of course, we carefully prepared the results of our work in publish able form. We made a sincere effort to invite seminar speakers and lecturers to come to Oak Ridge despite the sacrifices this presented to our early budget. We also had to do something more, and here I 'cashed in' on my experience of the previous 15 years. 404 pp. Englisch.…

Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -We characterize an isolated molecule by its compos~t~on, i.e. the number and types of atoms forming the molecule, its structure, i.e. the geometrical arrangement of the composite atoms with respect to each other, and its possible, i.e. quantum mechanically allowed, stationary energy states. Conceptually we separate the latter, being aware that this is an approximation, into electronic, vibrational and rotational states, including fine and hyperfine structure splittings. To be sure, there is an intimate relation between molecular structure and molecular energy states, in fact it is this relation we use, when we obtain structural information through spectroscopy, where we determine transitions between various stationary states of the molecule. The concepts above have proven extremely useful in chemistry and spectroscopy, however, the awareness of the limitations of these concepts has grown in recent years with the increasing recognition of (i) fluctional molecules, (ii) multiphoton absorption processes and (iii) influences due to the surroundings on 'isolated' molecules. 632 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -Science and art of crystal growth represent an interdisciplinary activity based on fundamental principles of physics, chemistry and crystallography. Crystal growth has contributed over the years essentially to a widening of knowledge in its basic disciplines and has penetrated practically into all fields of experimental natural sciences. It has acted, more over, in a steadily increasing manner as a link between science and technology as can be seen best, for example, from the achievements in modern microelectronics. The aim of the course 'Crystal Growth in Science and Technology' being to stress the interdisciplinary character of the subject, selected fundamental principles are reviewed in the following contributions and cross links between basic and applied aspects are illustrated. It is a very well-known fact that the intensive development of crystal growth has led to a progressive narrowing of interests in highly specialized directions which is in particular harmful to young research scientists. The organizers of the course did sincerely hope that the program would help to broaden up the horizon of the participants. It was equally their wish to contribute within the traditional spirit of the school of crystallography in Erice to the promotion of mutual understanding, personal friendship and future collaboration between all those who were present at the school. 440 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -Increasing international concern is being expressed regarding the contamination of the environment with polychlorinated dibenzo-p dioxins (PCDDs) and polychlorinated dibenzofurans because certain of these chemicals have been shown to be highly toxic to animals and are ubiquitous in the environment. They are known to be distributed as contaminants of commercial products and as by-products from com bustion processes. A considerable volume of information has accumulated on these chemicals in the past two decades, particularly for the most toxic of them, 2,3,7,8-tetrach1orodibenzo-p-dioxin (2,3,7,8-TCDD). However, this body of knowledge has not succeeded in resolving genuine judgmental differences among experts in the field as to the degree of hazard to human health and the environment. In light of the widespread public concern, it is clearly imperative to come to grips with the continuing scientific controversy, to review the data, assess the issues, to see where areas of agreement exist, and where further research is needed to resolve remaining areas of disagree ment. This volume represents an effort to contribute to these goals. 852 pp. Englisch.…

On Easter Monday in 1920, Otto Loewi was awakened in the night by a dream in which he conceived of neurotransmitters communicating across the synapse. He quickly made notes, but in the morning he could not understand his scribbles. The following night, the dream came again. He wrote down his thoughts more carefully and, the next day, conducted the crucial experiment that launched modern neu rophysiology (Koelle, 1986). Since the beginning of the modern era of sleep research in the 1950s, we have used the principles of neurotransmission to explore the regulation of sleep. Without resorting excessively to comments on blind men and elephants, however, it is fair to say that the phenomena of sleep and waking can be approached from many perspectives. Among other things, sleep is a process that can be described electri cally, an experience that so far defies physiological measurements, and a social behavior. In this book, I have tried to describe the physiology and pharmacology of sleep (Part I) and to relate them to clinical sleep disorders (Part II). Having neither the skill nor the grandiosity of Rous seau, I have made no attempt to write an encyclopedia of all that is known on the subject. Rather, I think of this book as more of a snap shot, giving a picture of where we are, and it is hoped, a history of how we got here. 460 pp. Englisch.…

One of its major aims was to increase interaction between these diverse groups which often use very different languages to describe similar concepts. The devel opment of a common language, or at least the acquisition of a multilingual capability, is a necessity if the field is to prosper. Much depends in this field on the interplay between theory and experiment. Accordingly this volume begins with two introduc tory chapters, one theoretical and the other experimental, which contain much of the background material needed for a through under standing of the field. The remaining sections describe a wide variety of applications and illustrate, we believe, the central role of charge densities in the understanding of chemical bonding. We are most indebted to the Divisions of Inorganic and Phy sical Chemistry of the American Chemical Society, which provided the stimulus for the symposium and gave generous financial support. We also gratefully acknowledge financial support from the Special Educational Opportunities Program of the Petroleum Research Fund administered by the American Chemical Society, which made exten sive participation by speakers from abroad possible. 492 pp. Englisch.…

Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume is the eighth in the Research Advances Series and the fifth published by Plenum Press. The purpose of the series is to review new work in rapidly changing fields. We do not expect reviews to cover the whole field of work on alcoholism and addiction. Nor do we expect that they will be like annual reviews covering all work in a delimited field. Our reviews are designed to explore only the most exciting parts of the total field and to focus on conclusions that can be made about them. The series publishes one volume each year. Volume 8 is an omnibus rather than a theme volume in that a wide range of topics is covered, including research on alcohol, opiates, and tobacco. As usual, the greater emphasis is on alcohol research, reflecting the importance of the problem and the volume of work to be reviewed. With Volume 8 come some changes in the Editorial Board. It will be the last volume in the series for Robert E. Popham who has resigned from the Board. He has been with the series since its inception and has contributed a great deal to its development. The members of the Board are grateful for his help. We are adding two new members: Dr. Howard Cappell, whose field is experimental psychology, and Dr. Edward M. Sellers, in clinical medicine and pharmacology. 352 pp. Englisch.…

Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The Third International School on Energetics was devoted to the subject of Energy for the Year 2000. By this title we hoped to avoid discussion of such matters as the role of OPEC in raising oil prices. In one sense, therefore, our task was made easier; we could merely look into our crystal balls. The choice of lecturers was made with the idea that no reason able source of energy can be overlooked. We omitted detailed lectures on oil and natural gas because we took it as a given fact that we would continue to use as much of these fuels as we can get at a reasonable price. To give us an overview we started the School by discussing U.S. energy policy and possible U.S. energy scenarios. As might be ex pected, there was some disagreement about the current energy program in the U.S., but little disagreement about the facts presented. 412 pp. Englisch. …

Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -For several years now scientific and medical sLaff have recognised the risks of toxicity of certain metals contained in alloys used in Lhe manufacture of biomaterials protheses, implants, and artificial organs. A number or scientific and industrial research centres have focussed their investigations in this direction and international societies and commissions have organised meetings with specialists from complementary disciplines in attendance in attempts to guage the importance of biological risks and to determine the toxicity of certain metals, with the aim of establishing preventive measures and guidelines. In the last century great efforts have been made to reduce unwanted biological effects caused by orthopaedic implants. The problems of pain and infection were overcome and the development of modern technology has resulted in a convincing decrease in corrosion problems and mechanical failure, such that ostosynthesis and endoprosthesis have rapidly progressed beyond the level of tentative investingation.llowever, a number of problems still remain to be solved, such as the influence of the material type on the healing process and its relative speed. The increasing use of cobalt-,chromium-and nickel-containing alloys in surgical and dental implants has raised various questions concerning the biological consequences of chronic internal release of these elements in the human body. A total of 55 delegates representing 16 countries heard presentations of fundamental aspects, local and remote tissue response, immunopathology, clinical aspects, and manufacturing qual ity control issues. 400 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -For the third time the Italian Group on Pattern Recogni tion has organized an International Conference on Image Analysis and Processing (lAP) gathering together the most active groups working in this area in our country. The first International Conference lAP was held in Pavia (1980) and the second one in Selva di Fasano (1982). A selected set of distinguished speakers has been invited to talk about their personal experience and views on industrial applications (H Freeman), the critical analysis of medical image processing (D Rutovitz), the advances of robot vision languages (M Silva) and the availability of AI technology for imI roving the performance of PR and IP programs (J M Chassery). Four different areas have been covered by the papers submitted and refereed) to the conference first and to a scientific committee next, namely IP Techniques, Multiprocessor Architectures, Robot Vision and IP Applications. A final paper giving the results of a census of the Italian groups is provided showing, with some detail, typical research lines as pursued in working groups both at the University and Industry. About 39 groups are presently active in 12 different places of the peninsula. 284 pp. Englisch.…
