Marine Geochemistry offers a fully comprehensive and integrated treatment of the chemistry of the oceans, their sediments and biota. It addresses the fundamental question 'How do the oceans work as a chemical system?' by capitalizing on the significant advances in understanding oceanic processes made over the past three decades. These advances have been facilitated by improved sampling and analytical techniques, a better understanding of theoretical concepts and the instigation of large-sized international oceanographic programs. Designed for use as a text, the book treats the oceans as a 'unified system' in which material stored in the sea water, the sediment and the rock reservoirs interacts to control the composition of sea water itself. Part I covers the transport of material to the oceans via rivers, the atmosphere and hydrothermal systems, and discusses their relative flux magnitudes. Part II considers the oceans as a reservoir, introducing water-column parameters before discussing water-column fluxes and the benthic boundary layer. Part III is devoted to the sediment reservoir. The topics covered include diagenesis, the major components of the sediments, and the processes controlling the geochemistry of oceanic deposit, which are discussed in t Read more...

It covers not just "whats" nutritional requirements but why they are required for human health, by describing their function at the cellular and molecular level. Each case study either leads to a subsequent discovery or enables an understanding of the physiological mechanisms of action of various nutrition-related processes. The text is "picture-oriented" and the commentary is directed towards explaining graphs, figures, and tables. Nutritional Biochemistry includes a discussion of relevant aspects of physiology, food chemistry, toxicology, pediatrics, and public health. Experimental techniques for nutritional science are emphasized, and primary data is included to help give students a feel for the nutrition literature. This "real-world" approach provides students with a realistic view of the basis for much of our understanding of nutritional biochemistry. * Integrates biochemistry and nutrition in a case-oriented method * Emphasizes a hands-on approach to learning - case histories and clinical and research data illustrate all major points * Places emphasis on metabolism - metabolic pathways, enzymology, nutrient requirements (including RDA values) * Reveals the benefits of the Mediterranean diet, the biochemistry of exercise, the cell signaling pathways, how nutrition can influence the development of cancer, and the anthropometry and genetics of obesity.

Compounds are substances that are two or more elements combined together chemically in a standard proportion by weight. Compounds are all around us - they include familiar things, such as water, and more esoteric substances, such as triuranium octaoxide, the most commonly occurring natural source for uranium. This reference guide gives us a tour of 100 of the most important, common, unusual, and intriguing compounds known to science. Each entry gives an extensive explanation of the composition, molecular formula, and chemical properties of the compound. In addition, each entry reviews the relevant chemistry, history, and uses of the compound, with discussions of the origin of the compound's name, the discovery or first synthesis of the compound, production statistics, and uses of the compound.

Volumes 26 and 27 have dealt with electrochemical reactions. The present volume therefore covers those interfacial processes which involve no net passage of current. The first chapter covers the structure of the interfacial region and its experimental investigation. The second chapter reviews the mechanisms by which heterogeneous catalysis of solution reactions can take place. The third is concerned with the mechanism and kinetics of crystal growth from solution. The final chapter deals with corrosion processes at the metal-solution interface. Read more...

This includes both state-of the-art fundamentals and innovative applications of these techniques. The authors present a deep analysis of their particular subjects in a way to address the needs of novice researchers such as graduate students and post-doctoral scholars as well as of established researchers seeking new avenues. Researchers and practitioners who need a solid foundation or reference will find this work invaluable. This second of two volumes covers the incorporation of periodic structures in waveguides to exploit the Bragg phenomenon, optical fiber sensors, hollow waveguides and micro-resonators as well as a review of the tremendous expansion of terahertz technology for sensing applications.
