Buch. Etat : 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. \*Presents the theory of hydrodynamic and pollutant transport modelling in lakes and coastal areas \* Thoroughly examines the issues and limitations of the numerical approaches used in hydrodynamic and pollutant transport modelling\* Demonstrates the calibration and verification of hydrodynamic and pollutant transport models using laboratory and field data.

Buch. Etat : Neu. Neuware - The different LC-MS techniques available today were developed to suit specific analytical needs and the application range covered by each one is wide, but still limited. GC amenable compounds can be all analyzed with a single GC-MS system whereas HPLC applications call for specific LC-MS instrumental arrangements. ESI, APCI, APPI, and EI are ionization techniques that can be combined with different analyzers, in single or tandem configuration, to create the ultimate system for a certain application. Once approaching LC-MS for a specific need, the fast technical evolution and the variegated commercial offer can induce confusion in the potential user.The role of this book is to enlighten the state-of-the-art of LC-MS evolution through a series of contributions written by the people that brought major, recent innovations in the field. Each chapter will take into consideration the novelties, the advantages and the possible applications covered by a particular technical solution.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The present book describes a large variety of different types of chain systems (nanowires), including shorter chains that are artificially produced for instance in break-junction experiments, chains synthesized as guests inside the channels of a host crystal, crystalline chain compounds, organic polymers (synthetic metals), and charge-transfer salts, thus covering an unusual wealth of systems. Both experimental and theoretical studies are discussed. Particular emphasis is put on illustrating the special phenomena that occur in such quasi-one-dimensional systems, and how theoretical and experimental efforts have been used in identifying those properties that are specific for truly one-dimensional systems from those of quasi-one-dimensional systems.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Food and beverages can be very aggressive chemical milieu and may interact strongly with materials that they touch. Whenever food is placed in contact with another substance, there is a risk that chemicals from the contact material may migrate into the food. These chemicals may be harmful if ingested in large quantities, or impart a taint or odour to the food, negatively affecting food quality. Food packaging is the most obvious example of a food contact material. As the demand for pre-packaged foods increases, so might the potential risk to consumers from the release of chemicals into the food product.
