Buch. Zustand: Neu. Neuware - In accordance with the developments in computation, theoretical studies on numerical schemes are now fruitful and highly needed. In 1991 an article on the finite element method applied to evolutionary problems was published. Following the method, basically this book studies various schemes from operator theoretical points of view. Many parts are devoted to the finite element method, but other schemes and problems (charge simulation method, domain decomposition method, nonlinear problems, and so forth) are also discussed, motivated by the observation that practically useful schemes have fine mathematical structures and the converses are also true. This book has the following chapters: 1. Boundary Value Problems and FEM. 2. Semigroup Theory and FEM. 3. Evolution Equations and FEM. 4. Other Methods in Time Discretization. 5. Other Methods in Space Discretization. 6. Nonlinear Problems. 7. Domain Decomposition Method.

Buch. Zustand: Neu. Neuware - NMR is a growing technique which represents a generalized, spread, common tool for spectroscopy and for structural and dynamic investigation. Part of the field of competence of NMR is represented by molecules with unpaired electrons, which are called paramagnetic. The presence of unpaired electrons is at the same time a drawback (negative effect) and a precious source of information about structure and dynamics. New phenomena and effects are described which are due to the high magnetic fields and advances in the methodology. Solution NMR of Paramagnetic Molecules is unique in dealing with these matters. The scope is that of presenting a complete description, which is both rigorous and pictorial, of theory and experiments of NMR of paramagnetic molecules in solution. Pertinent examples are described. From the time dependent behaviour of electrons in the various metal ions including polimetallic systems to the hyperfine-based information, and from NMR experiments to constraints for solution structure determination. The book's major theme is how to perform high resolution NMR experiments and how to obtain structural and dynamic information on paramagnetic metal ion containing systems.

Buch. Zustand: Neu. Neuware - The papers assembled in this volume were originally presented at the joint meeting of the Phytochemical Society of North America and the Mid-Atlantic Plant Molecular Biology Society, in August 2000. The symposium from which these chapters were prepared was entitled 'Regulation of Phytochemicals by Molecular Techniques' and was organised by James Saunders and Ben Matthews. This joint meeting was timely because of recent landmark advances in molecular biology and genomics as well as the renewed interest in phytochemistry as a rich source of nutraceuticals, drugs, and alternatives to synthetic agriculture pesticides. Progress in genome sequencing in plants such as Arabidopsis and rice has been remarkable, as have expressed sequence tag (EST) projects in other plants, including maize and soybean. Recently, private and public sector participants of the Human Genome Project announced that a rough draft of the human genome has been constructed. These advances directly influence phytochemical investigations by providing both insight and tools for exploring and manipulating genomes.

Buch. Zustand: Neu. Neuware - In previous volumes in this series, Advances in Metal and Semiconductor Clusters, the focus has been on atomic clusters of metals, semiconductors and carbon. Fundamental gas phase studies have been surveyed, and most recently scientists have explored new materials which can be produced from clusters or cluster precursors. In this latest volume, the focus shifts to clusters composed primarily of non-metal molecules or atoms which have one or more metal atoms seeded into the cluster as an impurity. These clusters provide model systems for metal ion solvation processes and metal-ligand interactions.Metal-ligand bonding underlies the vast fields of organometallic chemistry, transition metal chemistry and homogeneous catalysis. Catalytic activity, ligand displacement reactions and photochemical activity depend on the specific details of metal-ligand bonding. Likewise, metal ions are ubiquitous in chemistry and biology and weaker electrostatic interactions play a leading role in their function. In solution, metals exist in different charge states depending on the conditions, and the solvation environment strongly influences their chemistry. Many enzymes have metal ions at their active sites, and electrostatic interactions influence the selectivity for metal ion transport through cell membranes. Metal ions (e.g., Mg+, Ca+) are deposited into the earth's atmosphere by meteor ablation, resulting in a rich variety of atmospheric chemistry. Similarly, metal ions ( Mg+) have been observed in planetary atmospheres and in the impact of the comet Shoemaker-Levy 9 on Jupiter. In various circumstances, the electrostatic interactions of metal ions determine the outcome of significant chemistry.Cluster chemistry has made significant contributions to the understanding of these stronger metal ligand interactions and weaker metal ion solvation interactions. In this volume, the authors explore a variety of work in these general areas, where new cluster science techniques i.

Buch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The food industry faces an unprecedented level of scrutiny. Consumers are not only concerned with the safety and quality of food products but also the way in which they are produced. At the same time the food industry has developed new ways of assuring appropriate standards for its products and their methods of production, developing systems such as TQM and HACCP to identify and manage key steps in production. These new methods require new skills in auditing. Auditing in the food industry provides an authoritative guide to the range of standards and the auditing skills they demand.Part one sets the scene with an introductory chapter reviewing developments in standards affecting the food industry. There then follows chapters on how retailers audit their suppliers and how governments have moved from a traditional inspection role to one of 'regulatory verification' with its emphasis on auditing the robustness of a business's own systems for managing safety and quality.Part two examines the key aspects of safety and quality. A first chapter reviews the ways retailers assess supplier HACCP systems. There is then a chapter reviewing TQM systems that provides a context for a discussion of auditing techniques for HACCP-based quality systems. A final chapter looks at standards governing the analytical methods used in safety and quality control.Part three considers newer standards that are becoming increasingly important in the food industry. There are chapters on benchmarking an organisation against others as a way of improving performance, auditing the impact of food processing operations on the environment and auditing organic food processing.Auditing in the food industry is a valuable guide to the range of standards facing the food industry and the ways it can audit, and thus improve the quality of its performance. 232 pp. Englisch.

Buch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In 1912 Victor Franz Hess made the revolutionary discovery that ionizing radiation is incident upon the Earth from outer space. He showed with ground-based and balloon-borne detectors that the intensity of the radiation did not change significantly between day and night. Consequently, the sun could not be regarded as the sources of this radiation and the question of its origin remained unanswered. Today, almost one hundred years later the question of the origin of the cosmic radiation still remains a mystery.Hess' discovery has given an enormous impetus to large areas of science, in particular to physics, and has played a major role in the formation of our current understanding of universal evolution. For example, the development of new fields of research such as elementary particle physics, modern astrophysics and cosmology are direct consequences of this discovery. Over the years the field of cosmic ray research has evolved in various directions: Firstly, the field of particle physics that was initiated by the discovery of many so-called elementary particles in the cosmic radiation. There is a strong trend from the accelerator physics community to reenter the field of cosmic ray physics, now under the name of astroparticle physics. Secondly, an important branch of cosmic ray physics that has rapidly evolved in conjunction with space exploration concerns the low energy portion of the cosmic ray spectrum. Thirdly, the branch of research that is concerned with the origin, acceleration and propagation of the cosmic radiation represents a great challenge for astrophysics, astronomy and cosmology. Presently very popular fields of research have rapidly evolved, such as high-energy gamma ray and neutrino astronomy. In addition, high-energy neutrino astronomy may soon initiate as a likely spin-off neutrino tomography of the Earth and thus open a unique new branch of geophysical research of the interior of the Earth. Finally, of considerable interest are the biological and medical aspects of the cosmic radiation because of it ionizing character and the inevitable irradiation to which we are exposed. This book is a reference manual for researchers and students of cosmic ray physics and associated fields and phenomena. It is not intended to be a tutorial. However, the book contains an adequate amount of background materials that its content should be useful to a broad community of scientists and professionals. The present book contains chiefly a data collection in compact form that covers the cosmic radiation in the vicinity of the Earth, in the Earth's atmosphere, at sea level and underground. Included are predominantly experimental but also theoretical data. In addition the book contains related data, definitions and important relations. The aim of this book is to offer the reader in a single volume a readily available comprehensive set of data that will save him the need of frequent time consuming literature searches. 1112 pp. Englisch.
