Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Darwin's theory of evolution by natural selection was based on the observation that there is variation between individuals within the same species. This fundamental observation is a central concept in evolutionary biology. However, variation is only rarely treated directly. It has remained peripheral to the study of mechanisms of evolutionary change. The explosion of knowledge in genetics, developmental biology, and the ongoing synthesis of evolutionary and developmental biology has made it possible for us to study the factors that limit, enhance, or structure variation at the level of an animals' physical appearance and behavior. Knowledge of the significance of variability is crucial to this emerging synthesis. Variation situates the role of variability within this broad framework, bringing variation back to the center of the evolutionary stage. 592 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book describes the underlying water conditions and geologies that support viable riparia, illustrates the ecological characteristics of riparia, and discusses how riparia are used by human cultures as well as how riparia can be used to sustain environmental quality. In recent years riparian management has been widely implemented as a means of improving fisheries, water quality, and habitat for endangered species. This book provides the basic knowledge necessary to implement successful, long-term management and rehabilitation programs. 488 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Vascular Transport in Plants provides an up-to-date synthesis of new research on the biology of long distance transport processes in plants. It is a valuable resource and reference for researchers and graduate level students in physiology, molecular biology, physiology, ecology, ecological physiology, development, and all applied disciplines related to agriculture, horticulture, forestry and biotechnology. The book considers long-distance transport from the perspective of molecular level processes to whole plant function, allowing readers to integrate information relating to vascular transport across multiple scales. The book is unique in presenting xylem and phloem transport processes in plants together in a comparative style that emphasizes the important interactions between these two parallel transport systems. 592 pp. Englisch.

It provides a historical and autobiographical perspective of the developments in the field through the contributions of leading individuals who reflect on their careers and their impact on biochemistry. Volume 44 is essential reading for everyone from graduate student to professor, placing in context major advances not only in biochemical terms but in relation to historical and social developments. Readers will be delighted by the lively style and the insight into the lives and careers of leading scientists of their time. 438 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This sixth volume in this established series deals with the biochemical responses of fish to different environmental/ecological factors. Environmental Toxicology captures vital issues affecting the responses of fish to the chemical surroundings of their environment. Chapters included in this volume identify the systems found in fish to deal with xenobiotics, hormonal interactions initiated in the presence of these chemicals, the unique mechanisms used by fish to adjust to the present chemicals, and the new and evolving mixtures of chemicals in their environment. Also included, is a crucial review of the new methods being applied in fish systems to understand the effects of xenobiotics to fish fitness - a key theme in environmental health and critical to the future of fish populations. 560 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Fluorinated Materials for Energy Conversion offers advanced information on the application of fluorine chemistry to energy conversion materials for lithium batteries, fuel cells, solar cells and so on. Fluorine compounds and fluorination techniques have recently gained important roles in improving the electrochemical characteristics of such energy production devices. The book therefore focuses on new batteries with high performance, the improvements of cell performance and the improvement of electrode and cell characteristics. The authors present new information on the effect of fluorine and how to make use of fluorination techniques and fluorine compounds. With emphasis on recent developments, this book is suitable for students, researchers and engineers working in chemistry, materials science and electrical engineering. 592 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Nanoporous Materials IV contains the invited lectures and peer-reviewed oral and poster contributions to be presented at the 4th International Symposium on Nanoporous Materials, which will be hosted in Niagara Falls, Ontario, Canada, June 7-10, 2005. This volume covers complementary approaches to and recent advances in the field of nanostructured materials with pore sizes larger than 1nm, such as periodic mesoporous molecular sieves (e.g., MCM-41 and SBA-15) and related materials including clays, ordered mesoporous carbons, colloidal crystal templated materials, porous polymers and sol gels. The broad range of topics covered in relation to the synthesis and characterization of ordered mesoporous materials are of great importance for advanced adsorption, catalytic, separation and environmental processes as well as for the development of nanotechnology. This volume contains over 120 contributions related to the synthesis of ordered mesoporous silicas, organosilicas, nonsiliceous inorganic materials, carbons, polymers and related materials, their characterization and applications in adsorption, catalysis and environmental clean up. 980 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Proceedings of the world renowned ERCOFTAC (International Symposium on Engineering Turbulence Modelling and Measurements).The proceedings include papers dealing with the following areas of turbulence: Eddy-viscosity and second-order RANS models Direct and large-eddy simulations and deductions for conventional modelling Measurement and visualization techniques, experimental studies Turbulence control Transition and effects of curvature, rotation and buoyancy on turbulence Aero-acoustics Heat and mass transfer and chemically reacting flows Compressible flows, shock phenomena Two-phase flows Applications in aerospace engineering, turbomachinery and reciprocating engines, industrial aerodynamics and wind engineering, and selected chemical engineering problems Turbulence remains one of the key issues in tackling engineering flow problems. These problems are solved more and more by CFD analysis, the reliability of which depends strongly on the performance of the turbulence models employed. Successful simulation of turbulence requires the understanding of the complex physical phenomena involved and suitable models for describing the turbulent momentum, heat and mass transfer. For the understanding of turbulence phenomena, experiments are indispensable, but they are equally important for providing data for the development and testing of turbulence models and hence for CFD software validation. As in other fields of Science, in the rapidly developing discipline of turbulence, swift progress can be achieved only by keeping up to date with recent advances all over the world and by exchanging ideas with colleagues active in related fields. 1012 pp. Englisch.
