  • Atmospheric Ozone Research and its Policy Implications

    • 1st Edition
    • Volume 35
    • S.D. Lee + 3 more
    • English
    These proceedings describe the current state-of-the-art of ozone research. A wide range of topics is discussed including: emissions, transport and transformation of precursors of ozone and of ozone itself, the distribution of ozone, the deposition of ozone at the earth's surface, and its effects on man and the environment. Attention is also given to the role of stratospheric ozone and the role of the ultraviolet radiation which is transmitted through the ozone layer. Finally it describes in detail present and future policy measures to reduce the ozone in the lower atmosphere and to protect the ozone layer in the stratosphere.Many of the papers describe recent developments and new research results. Research carried out in both in Europe and in the United States is described, as are the policy measures which are being taken by both European and U.S. governments.

  • Advanced Scientific Computing in BASIC with Applications in Chemistry, Biology and Pharmacology

    • 1st Edition
    • Volume 4
    • P Valko + 1 more
    • English
    This book gives a practical introduction to numerical methods and presents BASIC subroutines for real-life computations in the areas of chemistry, biology, and pharmacology. The choice of BASIC as the programming language is motivated by its simplicity, its availability on all personal computers and by its power in data acquisition. While most of the scientific packages currently available in BASIC date back to the period of limited memory and speed, the subroutines presented here can handle a broad range of realistic problems with the power and sophistication needed by professionals and with simple, step-by-step instructions for students and beginners.Please note that a diskette containing the 37 program modules and 39 sample programs listed in the book is no longer available.The main task considered in the book is that of extracting useful information from measurements via modelling, simulation, and statistical data evaluations. Efficient and robust numerical methods have been chosen to solve related problems in numerical algebra, nonlinear equations and optimization, parameter estimation, signal processing, and differential equations. For each class of routines an introduction to the relevant theory and techniques is given, so that the reader will recognise and use the appropriate method for solving his or her particular problem. Simple examples illustrate the use and applicability of each method.

  • Natural Products Isolation

    Separation Methods for Antimicrobials, Antivirals and Enzyme Inhibitors
    • 1st Edition
    • Volume 43
    • G.H. Wagman + 1 more
    • English
    This new book encompasses, in great detail, the most recent progress made in the isolation and separation of natural products. It covers antibiotics, marine and plant-derived substances, enzyme inhibitors and interferons. The most recent separation methodology is described. Although there is a bias toward antibiotics, it was done because this is still the largest natural products area of research.The fourteen chapters are written by experts in their respective fields. The first two chapters are largely devoted to new methodology applied to purification of a variety of compounds. They include an extensive review and new applications of counter-current chromatography and the newly emerging HPLC-photodiode array technology. Chapter 3 provides a review of affinity chromatography applied to the separation of antibiotics for the first time. Next are chapters on antimicrobials with an update on all the most recent &bgr;-lactam (after 1976) discoveries. A comprehensive review of a very important class of antiparasitic agents - the avermectins - follows. An update of isolation and purification of a variety of marine-derived compounds is next. The succeeding chapter is a comprehensive review of the most recent developments in isolation and purification of interferons. This is followed by a discussion of enzyme inhibitors and their isolation and purification and ties in with a chapter on plant-derived natural products, some of which are also in this same category. The final chapter is a futuristic essay indicating the isolation of minute amounts of natural products and the fascinating biological properties which they possess.The book has extensive isolation schemes, tables, figures and chemical structures. In many instances a short summary of the producing organism, brief chemical description and structure and biological activity of the compounds is presented. Detailed information of extraction, separation and purification techniques follow. Each chapter has an extensive bibliography and, where applicable, an appendix showing sources of materials and equipment. A detailed index to the subject matter is included at the end of the book.The book thus offers the reader: up-to-date reviews (including 1988) of specific topics in the natural products field not to be found elsewhere; information on new chromatographic methods and techniques described in sufficient detail to be utilized by investigators in this area of research; and extensive references to enable the serious researcher to pursue particular information. It will appeal to pharmaceutical and natural products researchers and is a valuable acquisition for university chemistry and biochemistry departments.

  • Catalytic Processes Under Unsteady-State Conditions

    • 1st Edition
    • Volume 43
    • Y.S. Matros
    • English
    This book deals with catalytic processes under forced non-steady-state conditions. It demonstrates, both theoretically and practically, that forced non-steady-state processes are highly efficient compared with steady-state processes, and illustrates this with a wealth of practical examples.The first part of the book describes the theoretical and experimental basis of efficient processes, mathematical models of non-steady-state processes in reactors, influence of a non-steady-state catalyst surface, problems of optimization, the theory of a heat front in the fixed catalyst bed, and methods to create efficient cyclic regimes. The second part considers the following processes: sulphur dioxide oxidation in sulphuric acid production, cleaning of effluent gases from toxic impurities, production of high-potency heat, ammonia and methanol synthesis etc.The book will appeal to many readers: chemical engineers (especially in the field of mathematical modelling of reactors with a fixed catalyst bed); personnel of chemical plants and machine-manufacturin... companies dealing with maintenance and installation of catalytic reactors; specialists in detoxification of the effluents from organic admixtures and carbon monoxide; students of technical colleges and universities

  • Successful Design of Catalysts

    Future Requirements and Development
    • 1st Edition
    • Volume 44
    • T. Inui
    • English
    In July 1988, a Worldwide Catalysis Seminar was held to mark the 30th anniversary of the Catalysis Society of Japan. After the 9th International Congress on Catalysis in Calgary, about 25 Japanese researchers working on catalysis visited and held seminars in four countries. Each seminar focused on a specific subject, yet also covered a wide range of topics in catalysis, from the fundamental to the industrial stages. This volume, containing the proceedings of this unique event, reflects the successful way in which the seminars provided an opportunity for direct communication and discussion of how best to achieve the successful design of catalysts.

  • Diagenesis, II

    • 1st Edition
    • Volume 43
    • G.V. Chilingarian + 1 more
    • English
    Diagenesis is a highly developed, interdisciplinary field of study. It is reciprocal in that it borrows from numerous scientific or technological specialities and then, in turn, repays them with useful results. Too often, however, the information gained and concepts developed remain unintegrated instead of being utilized quickly by several related earth-science fraternities. This volume, the second of a multi-volume work, attempts to bring together such information, thereby assisting the individual and the research group in keeping up with the data explosion.There is no end in sight to diagenetic research because of its wide practical and intellectual appeals. Consequently, periodic reviews, such as presented in this volume, are greatly needed.

  • Green Marine Clays

    Oolitic Ironstone Facies, Verdine Facies, Glaucony Facies and Celadonite-Bearing Rock Facies - A Comparative Study
    • 1st Edition
    • Volume 45
    • G.S. Odin
    • English
    Green Marine Clays provides a comparative study of four authigenic marine clays: the well-known glaucony marine facies; the newly-identified sedimentary facies - verdine; the old oolitic ironstone facies; and the celadonite-bearing facies.The book demonstrates that the sea bottom plays host to a variety of clay minerals specific to the marine environment: ferric di-trioctahedral ``serpentine'', ferric chlorite, ferric smectite, ferric mica, ferric ``swelling chlorite'', all widespread in present oceans and all fundamentally formed by crystal growth and recrystallization processes in semi-confined marine microenvironments.A unique feature of the book is the inclusion of the first detailed study of the verdine facies characterized by a variety of authigenic green clays, some of which are new clay mineral species widespread in all tropical oceans. The celadonite-bearing facies has been studied intensively in the last few years and new results are obtained from deep sea samples and from land outcrops. The current knowledge is synthesized and reviewed in comparison with the glaucony facies. A new approach is adopted in the description of the old oolitic ironstone facies in which a comparison is made with the recent verdine facies.The material is abundantly illustrated throughout by 133 figures and 59 tables; 36 of the figures consist of plates showing 170 selected pictures obtained at different scales of observation including the field, binocular microscope, thin sections, transmission electron miscroscopy, scanning electron microscopy, high resolution transmission electron microscopy, X-ray diffraction. A subject index completes the book.The information presented here will help geologists construct a clearer picture of environmental and depositional history of rocks. It will appeal to sedimentologists interested in the processes by which, and the environment in which, clay minerals form. Clay mineralogists will find much useful information on a variety of iron rich minerals, and geochemists interested in the iron in the sea and those working with sedimentary iron ores will also benefit from the book.
