Buch. Condición: Neu. Neuware - Understanding and protecting our environment is a key component of environmental development, yet access to a wide range of high-quality information is currently based on very limited data due to lack of the exchange of data between source and recipient. This three part book that first discusses the importance of data exchange and describes why it is essential for gathering data in the environmental sciences. Part Two takes the results of the Environmental Data Exchange Network for Inland Water project (EDEN-IW), and addresses its objectives for ensuring that the needs of citizens and enterprises of the environmental sciences community are met. Finally, Part Three takes a look at the wide variety of data policies and addresses how environment administrators in Europe can enhance their efficiency, openness and accountability.…

Buch. Condición: Neu. Neuware - Hydrodynamic and pollutant transport models are useful tools for evaluating remediation options for polluted water bodies. These models span the range from highly theoretical, fine resolution, physically-based designs to lumped, black-box representations of real world phenomena. This book examines the numerical approaches used in hydrodynamic and pollutant transport modeling. First, the theory and physical basis of transport and mixing in lakes and coastal waters are provided. Methodologies that use a three-dimensional (3D) approach to predicting the fate and transport of pollutants are presented and this is followed by a presentation of alternatives to 3D circulation modeling as well as new advances in the field. These alternatives offer near 3D accuracy but without the computational burden. Illustrations of the calibration and verification of these models using laboratory data, as well as, field data are also provided. The models are applied to a diverse array of study sites ranging from The Great Lakes in North America to the coastal areas of Northern Crete.…

Buch. Condición: Neu. Neuware - UV-Visible Spectrophotometry of Water and Wastewater is the first book dedicated to the use of UV spectrophotometry for water and wastewater quality monitoring. Using practical examples the reader is shown how this technique can be a source of new methods of characterization and measurement. Easy and fast to run, this simple and robust analytical technique must be considered as one of the best ways to obtain a quantitative estimation of specific or aggregate parameters (eg. Nitrate, TOC), and simultaneously qualitative information on the global composition of water and its variation.\* First electronic library of UV-spectra providing data readily available for researchers and users\* Provides a theoretical basis for further research in the field of spectra exploitation\* Contains helpful practical applications.…

Buch. Condición: Neu. Neuware - The development of science, technology and industry in the near future requires new materials and devices, which will differ in many aspects from that of past years. This is due to the fact that many sophisticated processes and new materials are being invented. The computer engineering field is a typical example. The main building block for these achievements is science, and leading it is physics, which provides the foundation for the chemical, biological and atomic industries.Physics for Chemists contains many instructive examples complete with detailed analysis and tutorials to evaluate the student's level of understanding. Specifically it is focused to give a robust and relevant background to chemistry students and to eliminate those aspects of physics which are not relevant to these students.This book is aimed at chemistry students and researches who would by using the book, not only be able to perform relevant physical experiments, but would then also be in a position to provide a well founded explanation of the results.…

Buch. Condición: Neu. Neuware - In the past two decades there has been considerable work on global climatic change and its effect on the ecosphere, as well as on local and global environmental changes triggered by human activities. From the tropics to the Arctic, peatlands have developed under various geological conditions, and they provide good records of global and local changes since the Late Pleistocene.The objectives of the book are to analyze topics such as geological evolution of major peatlands basins; peatlands as self sustaining ecosystems; chemical environment of peatlands: water and peat chemistry; peatlands as archives of environmental changes; influence of peatlands on atmosphere: circular complex interactions; remote sensing studies of peatlands; peatlands as a resource; peatlands degradation, restoration, plus more.…

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Systems biology is a vigorous and expanding discipline, in many ways a successor to genomics and perhaps unprecedented in its combination of biology with a great many other sciences, from physics to ecology, from mathematics to medicine, and from philosophy to chemistry. Studying the philosophical foundations of systems biology may resolve a longer standing issue, i.e., the extent to which Biology is entitled to its own scientific foundations rather than being dominated by existing philosophies. 364 pp. Englisch. …

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The success of any drug discovery project relies upon the quality of the lead that initiates the lead optimization process. What defines a 'quality lead', where these 'quality leads' come from and how one discovers them has been the subject of intense debate within the pharmaceutical industry, relies upon defining those properties that historically have led to successful drug discovery. This volume addresses these questions and specifically discusses diabetes, obesity and tuberculosis. 236 pp. Englisch.…

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Computational elastohydrodynamics, a part of tribology, has existed happily enough for about fifty years without the use of accurate models for the rheology of the liquids used as lubricants. For low molecular weight liquids, such as low viscosity mineral oils, it has been possible to calculate, with precision, the film thickness in a concentrated contact provided that the pressure and temperature are relatively low, even when the pressure variation of viscosity is not accurately modelled in detail. Other successes have been more qualitative in nature, using effective properties which come from the fitting of parameters used in calculations to experimental measurements of the contact behaviour, friction or film thickness. High Pressure Rheology for Quantitative Elastohydrodynamics is intended to provide a sufficiently accurate framework for the rheology of liquids at elevated pressure that it may be possible for computational elastohydrodynamics to discover the relationships between the behaviour of a lubricated concentrated contact and the measurable properties of the liquid lubricant. The required high-pressure measurement techniques are revealed in detail and data are presented for chemically well-defined liquids that may be used as quantitative reference materials. 262 pp. Englisch.…
