Deep Convection and Deep Water Formation in the Oceans
1st Edition
Volume 57
Simon Chu + 1 more
English
This book contains articles presenting current knowledge about the formation and renewal of deep waters in the ocean. These articles were presented at an international workshop at the Naval Postgraduate School in Monterey in March 1990. It is the first book entirely devoted to the topic of deep water formation in which articles have been both selected and reviewed, and it is also the first time authors have addressed both surface and deep mixed layers. Highlighted are: past and recent observations (description and analysis), concepts and models, and modern techniques for future research. Thanks to spectacular advances realised in computing sciences over the last twenty years this volume includes a number of sophisticated numerical models. Observational as well as theoretical studies are presented and a clear distinction is established between open-ocean deep convection and shelf processes, both leading to deep- and bottom-water formation. The main subject addressed is the physical mechanism by which the deep water in the ocean can be renewed. Ventilation occurs at the surface in areas called the gills, where water is mixed and oxygenated before sinking and spreading in the abyss of the deep ocean. This phenomenon is a very active area for both experimentalists and theoreticians because of its strong implications for the understanding of the world ocean circulation and Earth climate. This major theme sheds light on specific and complex processes happening in very restricted areas still controlling three quarters of the total volume of the ocean. All articles include illustrations and a bibliography. This book will be of particular interest to physical oceanographers, earth scientists, environmentalists and climatologists.
Zeolite Chemistry and Catalysis
1st Edition
Volume 69
L. Kubelková + 3 more
English
These proceedings reflect recent developments in the field of zeolite chemistry and catalysis with an emphasis on the role of a modifying component on the properties of the molecular sieve material. The plenary lectures and contributed papers concentrate on the problem of isomorphous substitution in a zeolitic framework; on the occlusion and the structure of metal, metal oxide, and metal sulphide clusters and complexes in the intracrystalline void volume of molecular sieves and zeolites as well as in the interlaminar space of layered compounds.Catalytic applications are discussed, not only in regard to traditional hydrocarbon transformation, but also in such areas as: reduction of SO2, decomposition of NO, reactions of sulphur containing compounds and conversion of CO, CO2 to hydrocarbons or of alcohols to oxygenated products.Because the book provides valuable data and information on new achievements in the zeolite material science and application, it will be of considerable interest to all research groups involved in zeolite science.
Phylogenetic and Biochemical Perspectives
1st Edition
Volume 1
T.P. Mommsen + 1 more
English
This new series on The Biochemistry and Molecular Biology of Fishes grew out of the demand for state-of-the-art review articles in a rapidly expanding field of research. Up to the present, most research literature on biochemistry involved rats and humans, but new breakthroughs in the piscine setting have indicated that the field is ready for a review series of its own. Because of funding and experimental availability restrictions, most research in the field has dealt with fish and insects. Within the insect field, comparative biochemistry and comparative physiology have proceeded along independent paths as opposed to the piscine field, where the tendency has been for the latter to envelop the former.This volume sets out to make comparative biochemistry and comparative physiology independent of each other within the piscine setting, another important rationale for this review series as well as detailing the phylogenetic evolution of fishes. The goal of the series is to provide researchers and students with an appropriate balance between experimental results and theoretical concepts.
Handbook of Flotation Reagents: Chemistry, Theory and Practice
Volume 2: Flotation of Gold, PGM and Oxide Minerals
1st Edition
Srdjan M. Bulatovic
English
Handbook of Flotation Reagents: Chemistry, Theory and Practice: Flotation of Gold, PGM and Oxide Minerals, Volume 2 focuses on the theory, practice, and chemistry of flotation of gold, platinum group minerals (PGMs), and the major oxide minerals, along with rare earths. It examines separation methods whose effectiveness is limited when using conventional treatment processes and considers commercial plant practices for most oxide minerals, such as pyrochlore-containin... ores, copper cobalt ores, zinc ores, tin ores, and tantalum/niobium ores. It discusses the geology and mineralogy of gold, PGMs, and oxide minerals, as well as reagent and flotation practices in beneficiation. The book also looks at the factors affecting the floatability of gold minerals and describes PGM-dominated deposits such as Morensky-type deposits, hydrothermal deposits, and placer deposits. In addition, case studies of flotation and beneficiation in countries such as Canada, Africa, Russia, Chile, and Saudi Arabia are presented. This book will be useful to researchers, university students, and professors, as well as mineral processors faced with the problem of beneficiation of difficult-to-treat ores.
Highway Pollution
1st Edition
Volume 44
R.S. Hamilton + 1 more
English
Long before "green" issues became a subject of widespread concern, both editors of the present book were heavily involved in research relating to pollutants in the highway environment. The result was the First International Symposium on Highway Pollution in 1983 with subsequent Second and Third Symposia held in London and Munich respectively.The proceedings of these three conferences were published respectively as Volumes 33, 59, and 93 of The Science of the Total Environment which provided individual insights into developing research projects. This book is an attempt at a more coherent overview of highway pollution in which leading international authorities were invited to contribute their works.This book covers all aspects of air, water and noise pollution in the vicinity of highways. Sources, transport and effects are reviewed and control by engineering and legal procedures are considered. The current state of knowledge is put into perspective in this unique work.
Chemistry of the Platinum Group Metals
Recent Developments
1st Edition
Volume 11
F.R. Hartley
English
The chemistry of platinum group metals is a rapidly expanding commercially important field. It is dominated by the catalytic properties of the metals. They are useful in petrochemical and general chemical plants and are becoming increasingly important as autocatalysts for pollution control. The book covers recent developments in the chemistry of the six platinum group metals, namely, platinum, palladium, rhodium, iridium, ruthenium and osmium. The material falls into three broad areas. Firstly, the occurrence, extraction and use of the metals, especially in catalysis, electrochemistry, energy and electronics. Secondly, organometallic and homogeneous catalytic chemistry and last but not least coordination chemistry including biochemistry and cancer therapy. The work is aimed at scientists in universities and in industry using any of the six platinum group metals in research. It will be useful for those studying the compounds of the metals themselves, and those considering to use either the metals or their complexes and catalysts in their experimental work.
Cereal Grain
Mycotoxins, Fungi and Quality in Drying and Storage
1st Edition
Volume 26
J. Chelkowski
English
Fungi growth in the storage of cereal grain has led to serious losses of grain quality and quantity each year the world over. These fungi and moulds are capable of producing mycotoxins which accumulate in grains. This book contains reviews from 21 experts on the relationship between mould growth in grain and its effects as well as the accumulation of mycotoxins. Discussed are properties of "storage fungi" such as the water and temperature relationship, taxonomy and nomenclature aspects etc. New methods of storage allow for early detection of these mould growths. Significant attention is paid to Aspergillus and Penicillium species colonizing in cereal grain and their growth requirements. The book touches on the significance of mycotoxins in grain being used for food production and possible detoxification processes. There is considerable attention given to a new technique of decontamination in countries with humid climates involving proper drying techniques at low temperatures or heated air dryers. This volume covers numerous scientific and practical aspects of grain storage on farms and in industries which are important in preventing quality losses and contamination with mycotoxins.
Stationary Phases in Gas Chromatography
1st Edition
Volume 48
H. Rotzsche
English
The primary aim of this volume is to make the chemist familiar with the numerous stationary phases and column types, with their advantages and disadvantages, to help in the selection of the most suitable phase for the type of analytes under study. The book also provides detailed information on the chemical structure, physico-chemical behaviour, experimental applicability, physical data of liquid and solid stationary phases and solid supports. Such data were previously scattered throughout the literature. To understand the processes occurring in the separation column and to offer a manual both to the beginner and to the experienced chromatographer, one chapter is devoted to the basic theoretical aspects. Further, as the effectiveness of the stationary phase can only be considered in relation to the column type, a chapter on different column types and the arrangement of the stationary phase within the column is included.The secondary aim of this book is to stimulate the development of new and improved standardized stationary phases and columns, in order to improve the reproducibility of separations, as well as the range of applications.
Acidification Research in the Netherlands
Final Report of the Dutch Priority Programme on Acidification
1st Edition
Volume 46
T. Schneider + 1 more
English
This book contains the results and conclusions of extensive research on the causes and effects of acidification of forests/forest soils and heathland in the Netherlands. In 1985 the Dutch Priority Programme on Acidification was started in order to give a more concrete form to the increasing interest of policy-makers in the effects of air pollution on ecosystems in particular.In the last three years, the research has focused on obtaining a more accurate estimate of the emission of ammonia on the deposition of SOx, NOy and NHx, and also on quantifying effects on forest and heathland ecosystems. This quantification of effects included experimental work model analyses, and derivation of critical loads and levels for forest and heathland ecosystems. Furthermore, scenario analyses were made with the Dutch Acidification Systems Model (DAS) in order to evaluate the effectiveness of policy measures.The research itself, which formed the basis for this book, has been described in the reports on individual projects. A summary of the scientific results and conclusions is given in thematic reports (added as annex). An independent Review Team has provided a critical assessment of the research carried out since 1988. The Review Report has been incorporated as annex.
