Diversity Of Environmental Biogeochemistry

by J. Berthelin

75,51€ + 10% CARD

 Biogeochemistry, still in its formative stage twenty years ago, is now a young, interdisciplinary subfield of earth sciences, life sciences and chemistry. An international scientific association (International Symposia on Environmental Biogeochemistry incorporated - ISEB) was founded to organize international symposia to bring together microbiologists, biologists, chemists, geochemists, soil scientists, oceanographers, ecologists and environmental engineers interested in the biogeochemistry of terrestrial, aquatic and atmospheric environments.After the 8th ISEB held in Nancy, France, this volume was compiled. These fifty selected contributions from specialists of varying backgrounds and interests show the diversity and the common framework of the direct or indirect interactions of living organisms and their abiotic environments.

Helium Isotopes In Nature

by B.A. Mamyrin e I.N. Tolstikhin

58,29€ + 10% CARD

 <i>Developments in Geochemistry, Volume 3: Helium Isotopes in Nature</i> presents the isotopic investigations of noble gases. This book describes the origin, the history, and the contemporary distribution of isotopes of helium. Organized into 11 chapters, this volume begins with an overview of mass-spectrometric methods and measurements of the helium isotope abundance. This text then discusses the methods of collecting various terrestrial samples as well as the apparatus for helium extraction, volumetric measurements, and purification. Other chapters consider the isotope composition of primordial, radiogenic, and spallogenic light noble gases. This book discusses as well the origin and distribution of helium isotopes in meteorites, in the Earth''s mantle, the crust and ocean, and in the atmosphere. The final chapter deals with the scientific and applied problems that can be resolved to the progress in helium isotope geochemistry. This book is a valuable resource for scientists. Research workers and students interested in the geochemistry of helium will also find this book useful.

Rare Earth Element Geochemistry

75,51€ + 10% CARD

 Developments in Geochemistry, Volume 2: Rare Earth Element Geochemistry presents the remarkable developments in the chemistry and geochemistry of the rare earth elements. This book discusses the analytical techniques and the recognition that rare earth fractionation occurs naturally in different ways. Organized into 13 chapters, this volume begins with an overview of the wide array of types and sizes of the cation coordination polyhedral in rock-forming minerals. This text then examines the application of rare earth element abundances to petrogenetic problems that has centered on the evolution of igneous rocks. Other chapters consider the matching of observed rare earth element abundances with those provided by the theoretical modeling of petrogenetic processes. This book discusses as well the hypotheses on the genesis of a rock or mineral suite. The final chapter deals with the principal analytical methods. This book is a valuable resource for undergraduates, lecturers, and researchers who study petrology and geochemistry.

Silicate Glasses And Melts - Properties And Structure

by Bjorn Mysen e Pascal Richet

159,00€ + 10% CARD

 This book describes the structure-property-composition relationships for silicate glasses and melts of industrial and geological interest. From Antiquity to the 20th century, an introductory chapter presents this subject in a historical perspective. Basic concepts are then discussed in three chapters where attention is paid to the glass transition and its various consequences on melt and glass properties, to the structural and physical differences between amorphous and crystalline silicates, and to the mutual relationships between local order, energetics and physical properties. With pure SiO2 as a starting point, compositions of increasing chemical complexity are successively dealt with in a dozen chapters. The effects of network-modifying cations on structure and properties are first exemplified by alkali and alkaline earth elements. The specific influence of aluminum, iron, titanium, and phosphorus are then reviewed. With water, volatiles in the system COHS, noble gases, and halogens, the effects of volatile components are also described. The last chapter explains how the results obtained on simpler melts can be applied to chemically complex systems. In each chapter, physical and chemical properties are described first and followed by a review of glass and melt structure. When possible, pressure effects are also considered.*From SiO2 to complex silicate compositions, the physical and chemical properties of melts and glasses of geological and industrial interest*Structural characterization of melts and glasses, from ambient to high pressure and temperature*From basic concepts to an advanced level, a consistent description of the structure-property-composition relationships in glasses and melts

High Pressure Geochemistry & Mineral Physics - Basics For Planetology And Geo-Material Science

by S. Mitra

271,63€ + 10% CARD

 Significant achievements have been made at the cross-roads of physics and planetary science. In the second half of the twentieth century, the discipline of planetary sciences has witnessed three major episodes which have revolutionized its approach and content: (i) the plate-tectonic theory, (ii) human landing and discoveries in planetary astronomy and (iii) the extraordinary technical advancement in high P-T studies, which have been abetted by a vast improvement in computational methods. Using these new computational methods, such as first principles including ab initio models, calculations have been made for the electronic structure, bonding, thermal EOS, elasticity, melting, thermal conductivity and diffusivity. In this monograph, the boundaries of the definitions of a petrologist, geochemist, geophysicist or a mineralogist have been willfully eliminated to bring them all under the spectrum of "high-pressure geochemistry" when they deal with any material (quintessentially a chemical assemblage) - terrestrial or extraterrestrial - under the conditions of high-pressure and temperature. Thus, a petrologist using a spectrometer or any instrument for high-pressure studies of a rock or a mineral, or a geochemist using them for chemical synthesis and characterization, is better categorized as a "high-pressure geochemist" rather than any other kind of disciplinarian.The contents of this monograph bring together, under one cover, apparently disparate disciplines like solid-earth geophysics and geochemistry as well as material science and condensed-matter physics to present a thorough overview of high pressure geochemistry. Indeed, such interdisciplinary activities led to the discovery of new phenomena such as high P-T behaviour in metal oxides (e.g. Mott transition), novel transitions such as amorphization, changes in order-disorder in crystals and the anomalous properties of oxide melts.

Cryptosporidium - From Molecules To Disease

by Thompson

OUT OF STOCK OR NOT AVAILABLE

 In the relatively short period since Cryptosporidium was recognised as a human pathogen, and that it could be transmitted in water as well as directly between animals and people, it has been the subject of intense investigations. This work offers a comprehensive look at Cryptosporidium and cryptosporidiosis.
