  • Advances in Water Pollution Research

    Proceedings of the Fourth International Conference held in Prague 1969
    • 1st Edition
    • S. H. Jenkins
    • English
    Advances in Water Pollution Research contains the papers that were presented at the Fourth Conference of the International Association on Water Pollution Research, held in Prague, Czech Republic, on September 2–6, 1968. This book provides information on a wide variety of subjects concerned with research on water pollution. Organized into three sections encompassing 55 chapters, this book begins with an overview of the self-purification of flowing surface waters, which is a natural, complex physico-biochemical phenomenon that has special significance in canalized rivers. This text then examines the adoption of special measures to prevent stream pollution, which is caused by the ever-increasing amounts of industrial waste waters and sewage. Other chapters consider the factors that affect the variations of water quality in rivers, including the external effects and the quantitative or qualitative variations in the volume of flowing liquid. The final chapter deals with alternative cooling water systems. This book is a valuable resource for sanitary and civil engineers.

  • Regolith Exploration Geochemistry in Tropical and Subtropical Terrains

    • 1st Edition
    • Volume 4

    • English
    The use of exploration geochemistry has increased enormously in the last decade. The present volume specifically addresses those geochemical exploration practices appropriate for tropical, sub-tropical and adjacent areas – in environments ranging from rainforest to desert. Practical recommendations are made for the optimization of sampling, and analytical and interpretational procedures for exploration according to the particular nature of tropically weathered terrains. The underlying theme is the recognition that regions between 35°N and 35°S in particular have a common history of deep chemical weathering and lateritization during the late Mesozoic and early Tertiary. This has had a profound and lasting effect, so that the surface geochemical expressions of mineralization throughout these regions have many similar features, with local modification due to more recent weathering under changed climates.The volume discusses the data derived from numerous research and case studies in terms of exploration and dispersion models based on the weathering and geomorphological history. The models permit valid comparisons between equivalent terrains that may be geographically widely separated and situated in quite different climatic environments. The basis of the volume is to view geochemical dispersion within the context of a genetic understanding of the evolution of landforms and the regolith (i.e. landscape geochemistry) and to develop exploration procedures based on this understanding.This book should be of interest to exploration geochemists, economic geologists, soil scientists, geomorphologists and environmental geochemists.

  • Advances in Organic Geochemistry 1964

    Proceedings of the International Meeting in Rueil-Malmaison, 1964
    • 1st Edition
    • G. D. Hobson + 1 more
    • English
    Advances in Organic Geochemistry 1964 contains papers presented at the Second International Congress on Organic Geochemistry at Rueil-Malmaison, France on September 28-30, 1964. This collection discusses developments made in the field of organic-chemistry and the incorporation of organic matter with clay minerals. To understand the process involved in such association of materials, the text explains the overall reaction between the clay particles and all the organic and inorganic substances in the test solution. The study gives the trace element assemblages found in the Mansfield Marine Band as an example. Another study discusses the occurrence of isoprenoid alkanes in a Precambrian sediment where alkanes and porphyrin pigments, which remain stable for a long time in many geological conditions, can act as biological markers. The paper notes the Marker Bed of the Precambrian Nonesuch Shale Formation in Michigan. The book also presents more research such as those involving the Black Shales of the South-east Sicilian Triassic Basin and the Cretaceous Black Shales of the Cyrenaica Basin. The text then explains the use of electron spin resonance in studying concentrations of free radicals where the results of different measurements made on a Colorado coal are shown on a table. One paper addresses a study of the relative abundance of stable carbon isotopes as pointers to the evolution and genesis of petroleum. This collection will prove valuable for analytical and organic chemists, chemical engineers, geologists, and students of organic chemistry or geology.

    Semiconductor Heterojunctions investigates various aspects of semiconductor heterojunctions. Topics covered include the theory of heterojunctions and their energy band profiles, electrical and optoelectronic properties, and methods of preparation. A number of heterojunction devices are also considered, from photovoltaic converters to photodiodes, transistors, and injection lasers. Comprised of eight chapters, this volume begins with an overview of the theory of heterojunctions and a discussion on abrupt isotype and anisotype heterojunctions, along with graded heterojunctions. The reader is then introduced to the energy band profiles of isotype and anisotype heterojunctions, the practical aspects of their fabrication and characterization, and their electronic and optoelectronic properties. Some methods used in the preparation of heterojunctions are also described, including the chemical method, solution growth method, alloying method, and sputtering method. The remaining chapters focus on the characterization of the grown layers, examples of heterojunction devices, and experimental work on heterojunctions. This monograph is intended for research workers and graduate students.

  • Rock Dynamics and Geophysical Exploration

    • 1st Edition
    • Volume 8
    • L.N. Persen
    • English
    Rock Dynamics and Geophysical Exploration: Introduction to Stress Waves in Rocks deals with a theoretical tool for predicting stress waves in rocks. The book considers both elastic and Kelvin type materials, and also explains some experiments of stress waves in rocks. The book reviews concepts in the analysis of stresses and deformations, the fundamental equations used to examine the propagation of stress waves in certain types of solids, and the characteristics features of plane waves in elastic mediums. The text explains wave propagation in rocks due to a detonating charge (resulting in stress waves with a spherical symmetry), the response of a cylinder to an outside excitation (resulting in a cylindrical wave), or a harmonically oscillating stress from an outside excitation (resulting in a harmonic input pulse). The text explains Kelvin materials as a generalization of the behavior of the material where a damping effect is incorporated with the elastic medium being studied. The book also compares experimental results of the application of stress waves in rocks with theory, and explains the sensitivity criteria for tunnels. The text cites as an example, the significance of the interaction between tunnels and shock waves before any tunnel expansion can be made by engineers. The book will prove valuable for geologists or for structural, civil, and mining engineers.
