  • Selected Topics in the History of Biochemistry

    Personal Recollections, Part II
    • 1st Edition
    • Volume 36
    • G. Semenza
    • English
    One of the most exciting developments in biological sciences has been their merging with chemistry and physics resulting in the new disciplines of biochemistry, biophysics and molecular biology. As the developments of these new disciplines has been so rapid many of the key discoveries have occurred within the life-time of a number of prominent scientists in the field. The chapters in this and in future volumes are meant to complement with personal recollections by these scientists, the History of Biochemistry in this series (vols. 30-33 by M. Florkin and Vol. 34 by P. Laszlo). These bibliographic and autobiographic chapters convey to the reader lively, albeit at times subjective, views on both the scientific and social environments of the authors. The editor cosidered it presumptuous to give the authors narrow guidelines or to suggest changes in the chapters he received. The contributions assembled in this volume will convey the flavour of each author's particular personality.

  • Halogenated Biphenyls, Terphenyls, Naphthalenes, Dibenzodioxins and Related Products

    • 2nd Edition
    • R.D. Kimbrough + 1 more
    • English
    The chemical industry is increasingly faced with problems arizing from chemicals produced during the manufacture of halogenated biphenyls or phenols. Knowledge of these chemicals and their destructive properties is sporadic, and the acute toxicity of this group varies widely. This informative revised edition presents the chemistry, environmental pollution problems, animal toxicology and information about structure-activity relationships. A brief overview is given of worker exposure and occupational illness. The book is divided into three parts: chemistry and environmental contamination; experimental toxicology; and human exposure and effects. Because of the great deal of interest in these compounds much new research work has been conducted since the first edition of this book was published. This revised edition has retained the effectiveness and clarity of the first edition, while being supplemented with new information, condensed old information, and examples of recent incidents.

  • Principles of Induced Polarization for Geophysical Exploration

    • 1st Edition
    • Volume 5
    • J.S. Sumner
    • English
    Developments in Economic Geology, 5: Principles of Induced Polarization for Geophysical Exploration focuses on the principles, methodologies, and approaches involved in induced polarization (IP), including anisotropism, electromagnetic coupling, and electrical circuits. The book first takes a look at resistivity principles, theory of IP, and laboratory work in IP. Concerns cover electrical measurements of rocks, anisotropism, early part of decay curve and the comparison with frequency effects, electrical models of induced polarization, electrical polarization, resistivities of earth materials, and resistivity exploration methods. The manuscript then elaborates on IP field equipment, telluric noise and electromagnetic coupling, IP field surveying, and drill-hole and underground surveying and the negative IP effect. Discussions focus on differences between surface and subsurface methods, current-sending system in the field, telluric (earth) currents, electromagnetic coupling, design considerations, coupling of electrical circuits, design considerations, and signal-generating system. The manuscript ponders on the complex-resistivity method and interpretation of induced-polarization data, including grade estimation of mineralization using the IP method, complex-resistivity survey, signal detection capabilities of the complex-resistivity method, and disadvantages of the complex-resistivity method. The text is a valuable source of information for researchers wanting to study induced polarization.

  • Chemical Sensor Technology, Volume 4

    • 1st Edition
    • S. Yamauchi
    • English
    This volume is the fourth in a series of annual reviews on progress in the research and technology, both basic and applied, of chemical sensors. New principles, new devices, and the detailed mechanism of various chemical sensors are described. Chemical sensors continue to grow rapidly in importance encompassing a broad spectrum of technologies covering safety, pollution, fuel economy, medical engineering and industrial processes. More than half the papers in this volume are relevant to biosensing, a strategic field for medical and health care equipment, especially in geriatric medicine. Frequent health checks at home will be increasingly necessary as the proportion of the aged in the population steadily grows. In some cases health conditions will have to be monitored constantly to give warnings or provide emergency assistance at the right time. Because biochemical substances play major roles in physiological processes such as metabolism, excitation and contraction of skeletal muscle and neurotransmission, chemical sensing of the related biochemical substances will eventually become indispensable.Each chapter is written by an expert active in the front lines of chemical sensor research. Not only is the technological essence of the subject provided, but also the background and philosophy, an evaluation of achievements to date and problems to be dealt with. Each topic is described in sufficient depth to be useful to researchers worldwide.

  • Management of Semi-Arid Ecosystems

    • 1st Edition
    • Volume 7
    • B.H. Walker
    • English
    Extensive regions of the world have a climate which, whilst permitting development of a continuous vegetative cover, is too dry for successful annual cropping. These are the semi-arid areas where land use is based on the natural vegetation. Easily degraded and difficult to maintain, they are under increasing pressure as expanding human populations move in and endeavour to force a living from them. As a result they contain some of the worst examples of resource degradation.This book examines the problems and opportunities involved in man's use of semi-arid areas. The authors are all actively involved in research and land management in the areas discussed. Each chapter begins with a detailed, up-to-date account of the ecology of the region (its climate, soils, vegetation, fauna and main ecological characteristics). This is followed by a history of land use, problems involved in its management, a review of current research and recommended land use practices. The common features of semi-arid ecosystems are brought together in a final section.

  • Silica Glass and Binary Silicate Glasses

    • 1st Edition
    • Volume 15A
    • English
    Physical Sciences Data, Volume 15: Handbook of Glass Data: Silica Glass and Binary Silicate Glasses, Part A presents information on the systems capable of forming glasses by cooling melts. This book provides data on the crystallization rates of glasses. Organized into six chapters, this volume begins with an overview of the melt properties for the glass-forming systems. This text then examines the notion of a component that is very significant for determining the number of components in each investigated glass. Other chapters consider the contents of several oxides of the same element but in different valent state as the reason to transfer a glass to the category of the increased number of components. This book discusses as well the analytical composition of glass. The final chapter deals with flotation method using tetrabromoethane and benzene mixture. This book is a valuable resource for glass specialists, chemists, engineers, scientists, and information science workers.

  • Dielectrics in Time-Dependent Fields

    • 2nd Edition
    • Bozzano G Luisa
    • English
    Theory of Electric Polarization, Volume II: Dielectrics in Time-Dependent Fields focuses on the processes, reactions, and principles involved in the application of dielectrics in time-dependent fields, as well as the Kerr effect, statistical mechanics, and polarization. The publication first examines the phenomenological theory of linear dielectrics in time-dependent fields; empirical description of dielectric relaxation; and the relationship between macroscopic and molecular dielectric relaxation behavior. Concerns cover the relationship between macroscopic and microscopic correlation functions; statistical mechanics of linear dissipative systems and the relationship between response functions and correlation functions; superpositions of distribution functions; and the use of complex dielectric constant in problems with time-dependent field sources. The book then ponders on the dipole correlation function, polarization in the infrared and optical frequency range, and the Kerr effect and related phenomena. Discussions focus on the Kerr effect in condensed systems, extensions of the Kerr effect, extrapolation of the refractive index to infinite wavelength, results obtained from computer simulations, rotational diffusion, and general aspects of molecular reorientation. The manuscript tackles the dielectric properties of molecular solids and liquid crystals and experimental determination of permanent dipole and quadrupole moments. The text is a valuable source of data for researchers interested in the application of dielectrics in time-dependent fields.
