  • The Pocos de Caldas Project: Natural Analogues of Processes in a Radioactive Waste Repository

    • 1st Edition
    • N.A. Chapman + 3 more
    • English
    The safe disposal of radioactive wastes by burial in deep geological formations requires long-term predictions of the future behaviour of the wastes and their engineered repository. Such predictions can be tested by evaluating processes analogous to those which will occur in a repository, which have been long active in the natural geochemical environment. The Pocos de Caldas Project is a comprehensive study of two ore deposits in Minas Gerais, Brazil, aimed at looking at uranium and thorium series radionuclide and rare-earth element mobility, the development and movement of redox fronts, and the nature of natural groundwater colloids. A multidisciplinary team of experts from 27 laboratories carried out a fully integrated study of the geology, geomorphology, hydrogeology, geochemistry, hydrochemistry and geomicrobiology of the two sites for nearly four years. This book contains 20 papers covering the detailed findings, with particular emphasis on their significance for radioactive waste disposal, especially on the use of the data in testing models of radionuclide movement. It will interest economic geologists, geochemists and performance assessment modellers involved in the geological disposal of radioactive wastes.

  • Handbook of Mutagenicity Test Procedures

    • 2nd Edition
    • B.J. Kilbey + 3 more
    • English
    The compilation of this book was prompted by the necessity of a bench volume which could provide the necessary background information on materials, experimental design, pitfalls and dificulties, in order to perform a particular test in an acceptable way with a minimal need for additional expert help. This Second Edition updates this information, providing: - a comprehensive bench guide - methods known to be reliable - a broad spectrum of approaches - tips to avoid pitfalls when using unfamiliar techniques - data from population records - safety aspects of mutagens and carcinogens - basic statistical concepts for experiment design This `on the bench' methodological text provides the necessary information for most of the common assays for genetic damage in use. The book includes methods which have been sufficiently used and tested to make their use reliable, but also presents methods which are not widely used at present, but which might prove most useful in screening for mutagenic effects.

  • Engineering Turbulence Modelling and Experiments - 3

    • 1st Edition
    • G. Bergeles + 1 more
    • English
    This book presents and discussses new developments in the area of turbulence modelling and measurements, with particular emphasis on engineering-related problems. At present, turbulence is one of the key issues in tackling engineering flow problems. Powerful computers and numerical methods are now available for solving the flow equations, but the simulation of turbulence effects which are nearly always important in practice, is still in an unsatisfactory state and introduces considerable uncertainities in the accuracy of CFD calculations. These and other aspects of turbulence modelling and measurements are dealt with in detail by experts in the field. The resulting book is an up-to-date review of the most recent research in this exciting area.

  • Stereochemical and Stereophysical Behaviour of Macrocycles

    • 1st Edition
    • Volume 2
    • Bozzano G Luisa
    • English
    Stereochemical and Stereophysical Behavior of Macrocycles deals with the stereochemical and stereophysical properties of macrocyclic ligands and their coordination compounds. More specifically, the stereochemistry of metallic macrocyclics is discussed, along with the relationship between the thermodynamics and stereochemistry of macrocyclics and cryptates. The stereochemical aspects of the macrocycles of second and third row transition elements are also examined. Comprised of three chapters, this volume begins with an introduction to the stereochemistry of metallic macrocyclics as well as their structure, together with the conformation of their chemical rings and the steric effects of their coordination geometry. The next chapter considers the relationship between the thermodynamics and stereochemistry of macrocyclics and cryptates, with particular reference to the macrocyclic and cryptate effect. Cation-ligand interactions and solvent effects upon complex formation are described, along with macrocyclic and macrobicyclic ligands having different donor atoms. The final chapter is devoted to the stereochemical aspects of the macrocycles of transition metal ions, with additional comments on the stereochemistry of copper and nickel in unusual oxidation states. This book will be of interest to inorganic chemists.

  • Regional Studies

    • 1st Edition
    • Volume 5
    • Bozzano G Luisa
    • English
    Regional Studies is a collection of papers that deals with strata-bound mineral deposits in the Eastern Alps, in the Canadian Cordillera, in north-central, and southwest England. Other papers describe southern African stratiform ore deposits and the genesis of Irish base-metal deposits. One paper compares the various types of volcanogenic mineral deposits and their depositional environments characterized by distinct assemblages of volcanic rocks, which formed in the Northern Appalachians during certain episodes of the tectonic evolution. The paper notes that the youngest volcanogenic deposits of economic interest are tungsten—molybdenum—... base metal deposits in highly altered rhyolitic sub-volcanic complexes at Mount Pleasant, New Brunswick. Another paper reviews the mineral occurrences in southern Africa that include stratiform, non-magmatic, ore deposits, The paper considers a subdivision of deposits formed from surficial chemical processes during previous (or current) cycles of weathering and erosion. Many ore bodies have a dual origin: for example, the iron in the high-grade hematite deposits is partly syngenetic and partly epigenetic. The paper also illustrates the time-dependence of some stratiform ore deposits in southern Africa in a schematic diagram. Geologists, researchers, or engineers whose works are related with ore deposits and mining will benefit tremendously from the collection.

    • D. Kolymbas
    • English
    Constitutive modelling of granulate materials has achieved significant progress in recent times although some challenging problems still remain to be solved. Many of the 35 contributions in this volume are devoted to modelling but there are also papers investigating the phenomena to be modelled. For instance, there are reviews on several aspects of the behaviour of granulates which are mere material properties while other aspects are related to the ill-posedness of the corresponding boundary value problems. The work provides a comprehensive and up to date treatise on the theory of plasticity in granular materials, together with a great number of solution methods and applications. The volume is intended for researchers and practising engineers who wish to enhance their knowledge in this rapidly expanding field.
