    • 1st Edition
    • Volume 6
    • B.A. Fowler
    • English
    Topics in Environmental Health, Volume 6: Biological and Environmental Effects of Arsenic focuses on the properties, characteristics, and reactions of arsenic and its effects on the environment. The selection first tackles the mobilization of arsenic by natural and industrial processes and emissions, cycling, and effects of arsenic in soil ecosystems. Discussions focus on the effects of arsenic on plants and soil microorganisms, exposure through consumption, sources of arsenic, and mobilization of arsenic by natural processes and industrial activities. The publication then ponders on environmental reaction and analysis methods and arsenical metabolism and toxicity to freshwater and marine species. The text examines the metabolism of arsenic and epidemiology of human arsenic exposure, including acute and chronic effects by arsenic in man, absorption, tissue distribution and retention, and elimination and biological half-time. The publication then takes a look at the toxicity of arsenic and its compounds, as well as biological transformation of arsenic compounds in soil ecosystems and effects on plants; biotransformation of arsenic compounds and toxicity to freshwater and marine biota; and environmental transformation of arsenic in freshwater/marine ecosystems. The selection is a dependable reference for readers interested in the biological and environmental effects of arsenic.

  • Emerging Countries & World Summary

    Emerging Countries and World Summary
    • 3rd Edition
    • Kenneth F. Wilson
    • English
    Volume 3 of the definitive Market Reference to global electronics production and markets, with forecasts to 1997. The countries covered in this volume are China, Egypt, Greece, Mexico, New Zealand, Portugal, Puerto Rico, Saudi Arabia, Turkey and Venezuela.The aim is to cover all electronic products and components included in those products. These are grouped into 10 major categories which are common and directly comparable across all countries. Product groupings are further broken down in to sub-categories, the degree of detail of which, however, varies for each country depending on the importance of that product for each country and the availability of statistical sources.In compiling the Yearbook Series, trade statistics are analyzed in detail with over 350 separate catergories being employed. For some of the emerging countries, where trade statistics from a country are limited or unreliable, as in China, greater emphasis has been placed on trade statistics of countries trading with that country. Production statistics are collected from Government and Manufacturer's Association sources where these are available. Extensive use is also made of research reports, company reports, news items and work by other consultants to supplement and cross check the official and semi-official sources.From this "base year" estimates are built up, this being 1992 for the 1994 edition of the Yearbook. Production is then forecast for the next two years and markets for the next five. These forecasts are made in real terms using constant exchange rates and excluding inflation. Forecasts are based on the historical performance of each product, the general economic outlook, and the major growth influencing factors.Each new edition of the Yearbook is fully revised and updated with all sources being reanalysed in each successive edition.

  • Crop Photosynthesis

    Spatial and Temporal Determinants
    • 1st Edition
    • Volume 12
    • N.R. Baker + 1 more
    • English
    Since photosynthetic performance is a fundamental determinant of yield in the vast majority of crops, an understanding of the factors limiting photosynthetic productivity has a crucial role to play in crop improvement programmes.Photosynt... unlike the majority of physiological processes in plants, has been the subject of extensive studies at the molecular level for many years. This reductionist approach has resulted in the development of an impressive and detailed understanding of the mechanisms of light capture, energy transduction and carbohydrate biosynthesis, processes that are clearly central to the success of the plant and the productivity of crops.This volume examines in the widest context the factors determining the photosynthetic performance of crops. The emphasis throughout the book is on the setting for photosynthesis rather than the fundamental process itself.The book will prove useful to a wide range of plant scientists, and will encourage a more rapid integration of disciplines in the quest to understand and improve the productivity of crops by the procedures of classical breeding and genetic manipulation.

  • Soil Structure/Soil Biota Interrelationships

    International Workshop on Methods of Research on Soil Structure/Soil Biota Interrelationships, Held at the International Agricultural Centre, Wageningen, The Netherlands, 24-28 November 1991
    • 1st Edition

    • English
    Some pioneers in soil research such as Müller and Kubiëna were as much biologists as they were soil scientists and the legendary biologist Charles Darwin was foresighted in recognizing the earthworms as instrumental in reworking the soil, thereby forming what he called "vegetable mould". Still, soil science has largely been the realm of physicists and chemists over the past decades. Whatever the reason, this picture is rapidly changing. Until recently, research on the transport and transformation of elements in soil was often concerned with either soil biota/plant relationships or with soil structure/plant relationships, if the biota were considered at all, but very few studies explicitly took the interrelationships between soil structure and soil biota into account. The conference on Soil Structure/Soil Biota Interrelationships, held at Wageningen, The Netherlands, 24-28 November 1991, was meant to bridge that gap, focussing on methods of research, organized in three levels: features, processes and effects. The proceedings of the conference are testimony of the need to intertwine the biological, morphological, physical and chemical disciplines in soil research to understand better and forecast soil properties and processes as related to land use for agricultural and other purposes.This book should be of particular interest to soil scientists and ecologists who feel the need for a cross-disciplinary approach in soils research. It should also be a rich source of teaching material for courses in soil science and soil ecology at graduate level and above, with ample reference to studies on land use as related to agriculture and the environment.

  • Trace Elements in Igneous Petrology

    A Volume in Memory of Paul W. Gast
    • 1st Edition
    • Volume 5
    • C.J. Allègre + 1 more
    • English
    Trace Elements in Igneous Petrology, 5: Developments in Petrology: A Volume in Memory of Paul W. Gast focuses on the contributions and influence of Gast in petrology, including crystallization, magmatic processes, isotopic composition, and ocean ridge basalt chemistry. The selection first takes a look at quantitative models of trace element behavior in magmatic processes; application of trace elements to the petrogenesis of igneous rocks of granitic composition; and an assessment of local and regional isotopic equilibrium in the mantle. Discussions focus on evidence derived from time constraints, scale of isotopic disequilibrium, fractional crystallization, trace element modeling, geodynamics and tectonic setting, partition coefficients, quantitative models for trace elements, and parameter determination and inverse-problem solution. The publication then examines the isotopic composition of lead in oceanic basalt and its implication to mantle evolution; strontium isotopes in basalts from the Pacific Ocean basin; and trace elements in ocean ridge basalts. Concerns cover variations in ocean ridge basalt chemistry, trace elements in ocean ridge basalts, disequilibrium partial melting, seawater alteration, background for lead isotope tracer studies, and uranium, thorium, and lead concentrations in basalts. The book examines trace elements and anorthosite genesis, lead isotopes in Archaean plutonic rocks, early Archaean rocks and geochemical evolution of the earth's crust, and factors controlling the noble gas abundance patterns of deep-sea basalts. The selection is a valuable source of data for researchers interested in petrology.

  • Biological and Environmental Aspects of Chromium

    • 1st Edition
    • Volume 5
    • S. Langård
    • English
    Biological and Environmental Aspects of Chromium focuses on the biological and environmental aspects of chromium and its compounds, with emphasis on the most important aspects of their toxicology and physiology. Topics covered range from the production and occupational exposure of chromium compounds to the presence of chromium in air, soil, and natural waters. The applications of chromium in cell biology and medicine are also discussed. Comprised of 11 chapters, this volume begins with an overview of the toxic and carcinogenic effects of chromium and chromium compounds, followed by a discussion on the production and occupational exposure of chromium compounds. The reader is then introduced to the more common analytical methods used in the determination of chromium in environmental and biological samples. Subsequent chapters explore the nutritional role of chromium; absorption, transport, and excretion of chromium in humans and animals; mutagenic and cytogenetic effects of chromium compounds; and organ toxicity of chromium in animals. The carcinogenic effects of chromium, including its effects on the skin, are also considered. This monograph will be of interest to students, practitioners, and researchers in the fields of biology, physiology, and chemistry, as well as those with an objective interest in the ways in which chromium and its compounds act in biological materials and in the human environment.

    • Atta-ur- Rahman
    • English
    The field of nuclear magnetic resonance spectroscopy has undergone explosive development during the last decade with the advent of new one- and two-dimensional techniques. The author has had extensive experience in the use of these techniques for the structure elucidation of complex natural products, and in this book he gives a comprehensive, up-to-date and very readable account of these developments.The book's scope is very wide. It starts from fundamental principles of modern NMR spectroscopy, describing the instrumentation and its optimum use, and extends to the latest developments such as inverse measurements. Emphasis is on problem-solving so as to be useful to a large number of organic chemists, biochemists and medicinal chemists. The problems and worked solutions at the end of the chapters will help students to gain proficiency in the application of these new techniques. Those who are learning how to operate modern NMR spectrometers will find particularly useful the description of such basic aspects as shimming, probe tuning, and methods for improvement of resolution and sensitivity.
