Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -An integrated approach to environmental data management is necessitated by the complexity of the environmental problems that need to be addresses, coupled with the interdisciplinary approach that needs to be adopted to solve them. Agenda 21 of the Rio Environmental Conference mandated international programmes and organizations to take steps to develop common data and information management plans, and steps have been taken in this direction. The key word that defines the framework of the present book is `integration'. The book establishes the basics of integrated approaches and covers environmental data management systems within that framework, covering all aspects of data management, from objectives and constraints, design of data collection networks, statistical and physical sampling, remote sensing and GIS, databases, reliability of data, data analysis, and the transformation of data into information. 564 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Empirical Studies in Industrial Organization brings together leading scholars who present state-of-the-art research in the spirit of the structure-conduct-performance paradigm embodied in the work of Leonard W. Weiss. The individual chapters are generally empirically or public policy oriented. A number of them introduce new sources of data that, combined with the application of appropriate econometric techniques, enable new breakthroughs and insights on issues hotly debated in the industrial organization literature. For example, five of the chapters are devoted towards uncovering the link between market concentration and pricing behavior. While theoretical models have produced ambiguous predictions concerning the relationship between concentration and price these chapters, which span a number of different markets and situations, provide unequivocal evidence that a high level of market concentration tends to result in a higher level of prices. Three of the chapters explore the impact of market structure on production efficiency, and three other chapters focus on the role of industrial organization on public policy. Contributors include David B. Audretsch, Richard E. Caves, Mark J. Roberts, F.M. Scherer, John J. Siegfried and Hideki Yamawaki. 300 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -It is becoming increasingly clear that the future of the world cannot be sustained without scientific support, analysis, prediction and the use of scientific achievement. The immensity of the problems confronting us, coupled with the limited financial resources available, urgently demand the selection of priority areas of research, with a global combination of scientific effort. The new geopolitical situation has uncovered Russia's and the former Soviet Union's scientific potential. This has given rise to wider opportunities for involvement in work on international projects and programmes, many of which are discussed in the present volume. The book addresses specifically priority fields of science in which joint, multidisciplinary research should be developed, encompassing rational use of natural resources and regional sustainable development, as well as the monitoring of the biosphere's ecosystem state and the risks of natural and anthropogenic hazards, and the creation of new materials and technologies. The list of priorities includes Siberia's economic, social and humanitarian problems, as well as the development of information systems for the rapid exchange of scientific data. There is a recognised need for the involvement of young scientists in partnership laboratories, in a probationary capacity. 292 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Materials Chemistry is rapidly emerging as a key component of contemporary science. The strongly interdisciplinary nature of the field requires input from all branches of chemistry, from crystallography, from solid state physics and from computational and theoretical techniques. This book aims to give a coherent survey of the field by considering all the major aspects of the current study of the chemistry of materials. Early chapters emphasise basic principles and techniques. Strong emphasis is given to new techniques and technologies, for example, the opportunities opened up by new synchrotron sources in crystallography, and new computational techniques in simulation studies of complex materials. Characterisation techniques including crystallographic, microscopic and spectroscopic techniques are then described. Key contemporary themes such as atomic transport, reactivity and catalysis are reviewed. Later chapters focus on specific dasses of material, induding solid state ionics, ceramics (induding giant magneto-resistance and high temperature superconducting solids), microporous and molecular materials. We hope that the book provides a snapshot of the scientific and technological challenges in this fast developing field.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The explosion of new information on Helicobacter pylori-related disease, both in the basic sciences and in clinical medicine, has continued to progress at an unprecedented pace. In many instances H. pylori infection, both in man and in the laboratory animal, has become a model to investigate fundamental biological issues such as micro-organism-host interactions, intracellular signalling, development of mucosal atrophy, mechanism of microbial resistance, disease modifying factors etc. In view of this bewildering flood of new information, the time was considered right to organize yet another update on H. pylori in the successful series 'Basic mechanisms to clinical cure' to define the 'state-of-affairs' in H. pylori research at this time. Our main objective was to integrate this new information in a series of top-quality presentations and discussions between investigators and clinicians, addressing all aspects of H. pylori research, and to review the current position and future research direc tions. The format included state-of-the-art presentations by world experts heavily involved in H. pylori research, followed by in-depth discussion on intriguing or controversial issues. The topics discussed were grouped according to the leading theme: characteristics of the organism, mode of transmission, mechanisms of H. pylori-induced inflammation, causation of disturbances of gastric secretory and motor function, aspects of clinical presentation and management, problems related to H. pylori-associated gastric adenocarcinoma and MALT-lymphoma, novel aspects of antimicrobial therapy, and vaccination. The meeting concluded with a synoptic agenda of suggested future studies for the microbiologist, the histopathologist and the clinician. 528 pp. Englisch. …

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The double helix architecture of DNA was elucidated in 1953. Twenty years later, in 1973, the discovery of restriction enzymes helped to create recombinant DNA molecules in vitro. The implications of these powerful and novel methods of molecular biology, and their potential in the genetic manipulation and improvement of microbes, plants and animals, became increasingly evident, and led to the birth of modern biotechnology. The first transgenic plants in which a bacterial gene had been stably integrated were produced in 1983, and by 1993 transgenic plants had been produced in all major crop species, including the cereals and the legumes. These remarkable achievements have resulted in the production of crops that are resistant to potent but environmentally safe herbicides, or to viral pathogens and insect pests. In other instances genes have been introduced that delay fruit ripening, or increase starch content, or cause male sterility. Most of these manipulations are based on the introduction of a single gene - generally of bacterial origin - that regulates an important monogenic trait, into the crop of choice. Many of the engineered crops are now under field trials and are expected to be commercially produced within the next few years. The early successes in plant biotechnology led to the realization that further molecular improvement of plants will require a thorough understanding of the molecular basis of plant development, and the identification and character ization of genes that regulate agronomically important multi genic traits. 396 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Antennas are part of every radar, every communications system, and every electronic warfare system. Therefore antennas are an important technical subject. The number of antenna books that have been published in the last 5 years alone attest to this fact. But why another book about antennas What does this book offer that is different from all the others The answer is: accessibility. Most of the technical literature on antennas is written for those with extensive backgrounds in electromagnetic theory and familiarity with the mathematical language of vector analysis, differential equations, and special functions. This puts much of the antenna literature out of reach for the nonspecialist who needs to understand the subject but cannot afford the time required to become familiar with all the background material. With the rapid expansion of technical knowledge, the number of engi neering students who find themselves attracted to 'classical' subjects, such as electromagnetic theory, is on the decline, making it increasingly difficult to train engineers in areas involving antennas. Some authors in other technical fields have recognized this problem. For example, books on solid-state elec tronic devices that do not require an extensive background in quantum me chanics are available, useful, and informative. This book fulfills a similar Ileed in the area of antennas. 352 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Earthquakes and Atmospheric Hazards contains a selection of papers that were presented as part of the Sixth International Symposium on Natural and Man-Made Hazards (HAZARDS-96) held in Toronto, Canada during July, 1996. The Symposium was very timely, given the large number of natural disasters that have occurred in various parts of the world during the 1990s, the United Nations' International Decade for Natural Disaster Reduction (IDNDR). The human reaction to these disasters has varied widely from one event to the next and the economic and social costs have been immense with damage running into billions of dollars. Having in everyone's mind the Northridge, California (1994) and the Kobe, Japan (1995) earthquakes, the volcanoes in the Philippines, the cyclones and related storm surges in Bangladesh, and the floods in North America and Europe caused by heavy rains, the Symposium attracted more than one hundred papers covering various aspects of these events. The eleven papers included in this volume deal with the scientific and management issues of those earthquakes and atmospheric hazards that occurred during the late 1990s, with emphasis on the preparedness aspects. A summary report of the HAZARDS-96 Symposium and recommendations adopted by the participants is also included. Earthquakes and Atmospheric Hazards forms an excellent reference for scientists, students, engineers, the insurance industry, authorities specializing in public safety and natural hazards preparedness and mitigation plans. 208 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -It is now well recognised that many environments considered by man to be extreme are colonised by micro-organisms which are specifically adapted to these ecological niches. These organisms not only survive but actively grow under such conditions. A diverse range of bacteria, cyanobacteria, algae and yeasts has now been isolated from these habitats which are extreme in terms oftemperature, pH, salinity and pressure as well as species which are resistant to radiation and toxic chemicals. Whilst originally considered to be mere 'scientific curiosities', it is now generally accepted that many have con siderable biotechnological and commercial significance. Recently the term 'extremophile' has been used to describe these organisms. Over the past twenty years extensive studies of the ecology, physiology, taxonomy and molecular biology of these micro-organisms have been undertaken. These have resulted in a complete reassessment of our concept ofmicrobial evolution. The identification ofthe Archaeobacteria as the third kingdom ofliving organisms has given considerable impetus to extremophile research and is presenting many new challenges. 344 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume constitutes the Proceedings of the IUTAM Symposium on 'Nonlinear Analysis of Fracture', held in Cambridge from 3rd to 7th Septem ber 1995. Its objective was to assess and place on record the current state of understanding of this important class of phenomena, from the standpoints of mathematics, materials science, physics and engineering. All fracture phenomena are nonlinear; the reason for inclusion of this qualification in the title was to reflect the intention that emphasis should be placed on distinctive aspects of nonlinearity, not only with regard to material consti tutive behaviour but also with regard to insights gained, particularly from the mathematics and physics communities, during the recent dramatic ad vances in understanding of nonlinear systems in general. The expertise represented in the Symposium was accordingly very wide, and many of the world's greatest authorities in their respective fields participated. The Symposium remained focussed on issues of practical significance for fracture phenomena, with concentration on aspects that are still im perfectly understood. The most significant unifying issue in this regard is that of scale: this theme was addressed from several perspectives. One important aspect is the problem of passing information on one scale up or down, as an input for analysis at another scale. Although this is not always the case, it may be that the microscopic process of fracture is understood in some particular class of materials. 412 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Interstellar dust, meteorites, interplanetary dust particles (IDP's), the zodiacal light, comets, comet dust. Where do they come from, what are they made of, how do they evolve, and finally, are there connections between them These are the questions discussed in this volume by some of the world's outstanding experts in their respective fields. The techniques used for studying the `small' solid objects of space are thoroughly discussed. Some of the methods involve a synthetic approach using the laboratory to create analog environments and materials which are believed to resemble those in space. Others use direct laboratory methods with state-of-the-art analytical tools to study the material of the objects themselves - meteorites, IDP'S. And others apply the latest in astronomical facilities to provide quantitative data on the material properties of the solids which can only be deduced from remote observations, These are compared with the laboratory results. In one instance there was a possibility to study a solar system body in situ and that was the case of comet Halley and some of the results of these studies obtained from space `laboratories' launched to meet it are discussed here. Finally, there are theoretical papers which are aimed at bridging the results of observational and laboratory methods. This book is recommended to senior scientists as well as graduate students who wish to pursue research in interstellar and solar system astronomy and their connections. 616 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -These proceedings are based on the invited talks and selected research reports presented at the NATO Advanced Study Institute (ASI) on 'POLAR CAP BOUNDARY PHENOMENA' held at Longyearbyen, Svalbard, June 4 - 13, 1997. The role of the polar cap and its boundary is very substantial in solar-terrestrial physics. At this NATO AS! a major change in thinking on the 'cusp' precipitation region in the high-latitude days ide upper atmosphere was reflected, at least for intervals when the interplanetary magnetic field (IMF) is directed southward. It is likely that this has implications for northward IMF as well. The change comes from the now almost complete acceptance of the concept of magnetosheath particle entry along open magnetic field lines and the evolution of the precipitation into the upper atmosphere with time elapsed since magnetic reconnection which opened the field line. A key prediction of this view is that the low-latitude boundary layer (LLBL) is on open field lines. 456 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Toxicological and pharmacological effects arise when chemicals interact with biophysiological functions in discrete cell types. There is a continuing need to screen novel compounds for their potential therapeutic effects, and once these have been 'discovered' to understand their molecular actions, as the basis of using such compounds safely and for rational drug design. Pharmacology now uses all of the sophisticated molecular research techniques that are available for the development of safer and more efficacious drugs. Histochemistry has been usefully applied to developing new drugs (and assessing chemical safley) and is potentially cost effective. The need to test novel substances for their potential adverse effects has raised many questions. Toxicological pathology has moved away from the cataloging of lesions towards understanding the basis of the events that underly cell injury, especially for those secondary consequences of chemical injury that lead to malignancy and chronic disease. The focal nature of toxicologic lesions de mands the use of microtechniques to provide data to help understand these questions. Histochemistry is under-utilized, but offers one of the key ap proaches necessary to address the problem of understanding interactions between a cell population and a chemical, the modulation of cellular biochem istryor the presence of a lesion in a test animal can be rationalised in terms of species differences that have no relevance to man as opposed to those that are of clinical significance or represent a warning of dire consequences to man. 304 pp. Englisch.…

Ecclesiasticus 38:4, quoted by Selman Waksman when accepting the 1952 Nobel Prize for Medicine that was awarded for the discovery of the first effective antituberculosis drug. streptomycin. which was derived from the soil bacterium, Streptomyces grisells. 1. HISTORICAL PERSPECTIVE This book has been published at the close of the twentieth century when the medical profession and the general community are increasingly concerned about the threat of multidrug-resistant tuberculosis (MDRTB)[1. 2]. However, at this epoch, it is enlightening to move back from our immediate concerns about MDRTB 'hot spots' in Asia, South America, and the former Soviet Union [3], and to place our current predicament in an historical context. If the results of the global survey of antituberculosis drug resistance conducted by the World Health Organisation (WHO) and the International Union against Tuberculosis and Lung Disease (IUATLD) can be extrapolated, only 2. 2% of TB cases worldwide are due to multi drug resistant strains [3]. At the beginning of the 20th century, all TB cases were refractory to all available therapies. Great advances had been made during the 19th century in the understanding of the epidemiology and pathogenesis of TB, and in the diagnosis of the disease (reviewed in references 4-7). 332 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Advances in Turbulence VII contains an overview of the state of turbulence research with some bias towards work done in Europe. It represents an almost complete collection of the invited and contributed papers delivered at the Seventh European Turbulence Conference, sponsored by EUROMECH and ERCOFTAC and organized by the Observatoire de la Côte d'Azur. New high-Reynolds number experiments combined with new techniques of imaging, non-intrusive probing, processing and simulation provide high-quality data which put significant constraints on possible theories. For the first time, it has been shown, for a class of passive scalar problems, why dimensional analysis sometimes gives the wrong answers and how anomalous intermittency corrections can be calculated from first principles. The volume is thus geared towards specialists in the area of flow turbulence who could not attend the conference as well as anybody interested in this rapidly moving field. 644 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -It is well known that the density of molecular hydrogen can be increased by compression and/or cooling, the ultimate limit in density being that of liquid hydrogen. It is less well known that hydrogen densities of twice that of liquid hydrogen can be obtained by intercalating hydrogen gas into metals. The explanation of this unusual paradox is that the absorption of molecular hydrogen, which in TiFe and LaNis is reversible and occurs at ambient temperature and pressure, involves the formation of hydrogen atoms at the surface of a metal. The adsorbed hydrogen atom then donates its electron to the metal conduction band and migrates into the metal as the much smaller proton. These protons are easily accomodated in interstitial sites in the metal lattice, and the resulting metal hydrides can be thought of as compounds formed by the reaction of hydrogen with metals, alloys, and intermetallic compounds. The practical applications of metal hydrides span a wide range of technologies, a range which may be subdivided on the basis of the hydride property on which the application is based. The capacity of the metal hydrides for hydrogen absorption is the basis for batteries as well as for hydrogen storage, gettering, and purification. The temperature-pressure characteristics of metal hydrides are the basis for hydrogen compressors, sensors, and actuators. The latent heat of the hydride formation is the basis for heat storage, heat pumps, and refrigerators. 740 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -Significant vulnerability of water systems to drought is a common issue of water resources management in Mediterranean regions. This is due both to the increasing occurrence and severity of drought events and to the growing demand for municipal, tourist, and agricultural uses. The INCO-DC project entitled 'A Decision Support System for Mitigation of Drought Impacts in the Mediterranean Regions' (DSS DROUGHT) addresses this issue, contributing to an improved management of water supply systems for irrigation, which represents the most consumptive sector of water resources uses in the Mediterranean region. In order to develop a comprehensive approach toward improved operation of irrigation systems under drought conditions, the project was developed around the following five main, strictly interconnected tasks: Identification of drought characteristics at a site and over a region Modelling irrigation management under conditions of water scarcity Modelling operation of water supply systems under drought conditions Integration of the developed methodologies within a Decision Support System software package Definition of requisites for Drought Watch Systems The research resulted in an advancement of knowledge through in-depth analysis of innovative methodologies, the development of tools to help decision-makers in coping with droughts through the implementation of the developed procedures in software packages, and the application of these tools to the case-studies identified by partners in their countries. 372 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The continental shelf seas have an importance which is out of proportion to the rela tively small fraction of the area of the global ocean which they occupy. These shallow seas play an important role as the high energy boundary zones of the deep ocean where much of the ocean's tidal and wave energies are dissipated. They are highly productive biologically and are responsible for most of the world's fishery production. In many cases, they are also sources of economically important resources, notably hydrocarbons and they are frequently important as thorough fares for merchant shipping. Because they are the regions of the ocean closest to our centres of population and industrial activity, they have been the first to feel the impact of the increasing pressures imposed by large scale waste disposal into the ocean. The North Sea is an archetypal representative of such seas: we need to be able to understand its processes and predict them if we are to achieve a degree of rational management in the future, as the environmental threats increase. The understanding required extends through a wide range of processes that operate in the shelf seas from the fundamental physics to the chemistry and biology of the water column and the seabed sediments. These processes, and the interactions between them, cut across the traditional discipline boundaries within marine science and require a substantial inter disciplinary effort for their effective study. 256 pp. Englisch.…

This volume collects the lecture presentations and reports on the lively Panel discussions. The idea for the meeting evolved from a series of International Symposia on Quantum Chemistry and Mechanism in Heterogeneous Catalysis. The first of these was held in Lyon, France in 1986, the second in Krakow, Poland in 1988 and the third in Berkeley, California in 1990. The organising committee of the present meeting was Bernard Bigot, France, Tony Farragher, Netherlands, Richard Joyner, UK, Mme. Danielle Olivier, France, and Rutger van Santen, Netherlands, (Chairman). We wish to thank all members of the committee but in particular Bernard Bigot, who undertook the very extensive work involved in the local organisation with consummate skill and made our stay in Provence a great pleasure. Bernard Bigot's secretary, Mme. Marie-Noelle Coscat and Richard Joyner's secretary, Mrs. Pat Gibbs, also deserve our considerable thanks. There were fifty-four participants from eleven countries. 508 pp. Englisch.…
