Buch. Zustand: 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. Zustand: 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. Zustand: 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. Zustand: 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. Zustand: 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.…
