    • English
    Silicate Science, Volume VII: Glass Science reviews the advances made in silicate research from 1960 through 1970, with emphasis on glass science. Although much of the discussion is still based on the classic physical chemistry theories, an attempt is made to introduce the essential solid-state physics principles and to show how they can be applied to non-crystalline solids. The properties of many diverse vitreous materials are presented. Comprised of seven chapters, this volume begins with an overview of glass-forming elements and their compounds, paying particular attention to their general character as glass-forming phases. The properties of of chalcogenide glasses and non-silicate oxide glasses are also discussed. The next chapters focus on the viscosity of molten glass; the electrolytic conductivity of silicates; the specific volumina of glass melts; and specific applications of infrared spectroscopy to solving structure problems. The physical properties of glass, varied by thermal actions in the transformation and annealing ranges, are considered as well. The final chapter is devoted to miscellaneous additional constitution problems, with particular reference to the volatilization of lead silicate glasses from glass melts and vitreous semiconductors of chalcogenide glasses. This book will be of interest to mineralogists and crystallographers.

  • Atomic Radiative Processes

    • 1st Edition
    • Peter R. Fontana
    • English
    Atomic Radiative Processes provides a unified treatment of the theory of atomic radiative processes. Fourier transforms are used to obtain solutions of time-dependent Schrödinger equations, and coupled differential equations are transformed to coupled linear equations that in most cases can be readily solved. This book consists of nine chapters and begins with an overview of some of the properties of the classical field and its interaction with particles, focusing on those aspects needed for a better understanding of quantum theory. The Hamiltonian formalism is used to quantize the field, and the density of states of the radiation field is considered. The following chapters focus on a few Fourier transform techniques and their application to such areas as coherence properties of the field and amplitude and intensity correlations; the theory of angular momentum; the properties of irreducible tensors; quantization of the radiation field; and photon states. The interaction of a two-level atom with single modes of the radiation field is also discussed, along with spontaneous emission and decay processes; the evolution of coupled atomic states; the frequency distribution of emitted radiation; and radiative excitation and fluorescence. This monograph is intended for students and researchers in pure and applied physics.

  • Cerebral Lateralization in Nonhuman Species

    • 1st Edition
    • Stanley Glick
    • English
    Cerebral Lateralization in Nonhuman Species explores brain asymmetries in animals and the extent to which such asymmetries relate, in an evolutionary and clinical sense, to the pervasive asymmetries that characterize the human brain. Topics covered include cerebral lateralization in birds, rats, and nonhuman primates; the inheritance of direction and degree of asymmetry in the brain; the morphology of rat forebrain; and variation in the pattern of behavioral and brain asymmetries due to sex differences. Comprised of 11 chapters, this book opens with a historical overview of research into the cerebral lateralization of structures and functions in nonhuman species. The discussion then turns to lateralization of vocal control in songbirds and lateralization of several behaviors in domestic chicks. The inheritance of direction and degree of asymmetry is also considered, along with the morphology of rat forebrains. The following chapters focus on asymmetries in anatomy and pathology in the rodent brain; the link between brain lateralization and behavioral functions; and how early experiences can induce laterality. The final chapter analyzes the implications of brain asymmetries for evolution, genetics, and clinical syndromes. This monograph will be a useful resource for students, neuroscientists, clinicians, and other practitioners in fields ranging from psychobiology and psychology to anatomical sciences, neurobiology, neurochemistry, and genetics.

Discussions on the acute toxicity and carcinogenic activity of aflatoxins in laboratory and farm animals are also provided, with emphasis on the recognition of aflatoxicosis, a disease condition caused by the action of the aflatoxin poison. The book goes on examining the role of spoilage molds in destroying stored crops and the tremendous capacity for toxin production of aflatoxins. It also describes successful efforts of food and feed industries to ensure a wholesome food supply, including the utilization of various detoxification processes. The last chapters deal with the regulatory provisions for aflatoxin contamination control and tolerances and the implications of fungal toxins to human health. The book is intended for scientists and manufacturers concerned with the production and processing of foods and feeds, the nutrition, and the animal and public health.

  • Catalytic Reactions

    The Organic Chemistry of Palladium
    • 1st Edition
    • Peter Maitlis
    • English
    The Organic Chemistry of Palladium, Volume I1: Catalytic Reactions deals with organic transformations resulting from palladium complexes either stoichiometrically or catalytically. One feature of a reaction catalyzed by transition metals is the absence of evidence for the typical reactive intermediates of organic chemistry, carbanions, and carbonium ions. This lack of evidence is due to the metal acting both as a source and a sink of electrons that result in energetically unfavorable ionic intermediaries. The book explains that palladium (II) can induce C-O bond formation. These reactions involve oxidation of the organic substrate and reduces the Pd(II) to metal, and are not catalytic. Industrial applications can re-oxidize the palladium metal back to Pd(II) in situ, making the reactions catalytic. The text also discusses certain reactions that can form C-O bonds as part of an oxidative process. The book also describes significant reactions that can be catalyzed by palladium metal, such as in the hydrogenation of multiple bonds, in the carbonylation of certain olefins and acetylenes, and in the catalytic cracking of high molecular weight hydrocarbons. Organic chemists, analytical chemists, investigators, and scientists whose works involve physical or inorganic chemistry will find the book truly useful.

  • Water Activity and Food

    • 1st Edition
    • John Troller
    • English
    Water Activity and Food explores the role of water activity in the water relations of microorganisms and in food processing, packaging, and storage. It reviews the literature and provides numerous examples demonstrating the use of water activity to predict the reactions of microorganisms or the stability of food components. It also highlights cases where water activity is not a reliable predictor of events and considers some interesting interactions with other environmental parameters. Comprised of 11 chapters, this volume begins with an overview of water in foods and solutions, water activity values for foods, and water relations of enzyme activity. It then discusses lipid oxidation, enzyme reactions and non-enzymatic browning, and several other food-related factors. The reader is also introduced to water relations of microbial growth; the effects of water on microbial survival; the spoilage and preservation of foods at various levels of water activity; the water relations of food-borne pathogens such as Salmonella and toxigenic molds; the importance of water activity in non-microbiological aspects of food processing and storage; and the influence of atmospheric relative humidity on sanitation and the protection of food products. This book is an important source of information for researchers in food microbiology and microbial water relations.
