  • Chemisorption and Magnetization

    • 1st Edition
    • P. W. Selwood
    • English
    Chemisorption and Magnetization focuses on particle size determination and on the number of adsorbent atoms affected when any molecule is adsorbed on a surface. This book examines the adsorption of a molecule on the surface of a ferromagnetic solid that produces a change in the magnetization of the solid. Organized into 12 chapters, this book starts with an overview of the experimental methods used for studying chemisorption and magnetization, which are applicable in granulometry. This text then discusses the measurement of saturation magnetization in a ferromagnetic substance in the form of small particles. Other chapters consider the conditions in a typical nickel silica hydrogenation catalyst. This text examines as well the magnetization at moderate fields and near room temperature. The final chapter deals with the properties and complexities of palladium, platinum, and nickel. Students and researchers interested in heterogeneous catalysis and related areas will find this book extremely useful.

  • Relaxation Phenomena in condensed Matter Physics

    • 1st Edition
    • Sushanta Dattagupta
    • English
    Relaxation Phenomena in Condensed Matter Physics features various methods for spectroscopy techniques presented in this book and the relation of these techniques to correlation functions. This book aims to present the similarities and differences between different studies of the relaxation phenomena and to come up with a unified theoretical approach. This text is divided into two major parts, A and B. Part A deals briefly with several spectroscopy experiments and how they can be analyzed in terms of correlation functions. Spectroscopy techniques are likewise discussed in this part. Part B focuses on the stochastic theory of the said correlation functions, where each stochastic model is situated in the context of a physical process. The result of the calculations is then related to one of the experiments featured in Part A. These stochastic methods provide a simple mathematical framework in analyzing relaxation phenomena that can be related to diffusion process. This book is targeted to graduate students who have already taken quantum and statistical physics and is a good reference to students, scientists, and researchers in the field of condensed matter physics.

  • The Pyridine Nucleotide Coenzymes

    • 1st Edition
    • Johannes Everse
    • English
    The Pyridine Nucleotide Coenzymes provides a comprehensive discussion of the evolution, properties, and reactions of pyridine nucleotide coenzymes. The pyridine nucleotide coenzymes, NAD and NADP, appear to be among the most versatile of molecules with respect to their biological functions. In addition to their well-documented roles in a large number of oxidation-reduction reactions, these coenzymes are involved in many aspects of metabolic regulation. The book begins by tracing the evolution of coenzymes and pyridine nucleotide coenzymes. This is followed by separate chapters that deal with the static and dynamic properties of the pyridine nucleotide coenzymes; chemistry and solution conformation of the pyridine coenzymes; pyridine nucleotide analogs; and the three-dimensional structures of pyridine nucleotide binding enzymes. Subsequent chapters cover the synthesis and characterization of immobilized coenzymes and derivatives and their applications in affinity chromatography and enzyme reactors; the pathways to quinolinate, a major precursor of pyridine nucleotides; the role of pyridine nucleotides in phagocytosis; and non-oxidation-reduct... reactions of pyridine nucleotides.

  • Metabolic Aspects of Food Safety

    • 1st Edition
    • Francis Roe
    • English
    Metabolic Aspects of Food Safety is based on the proceedings of the Second Food Safety Conference held in 1969. The first conference was held in April 1966 and was concerned solely with the Pathology of Small Laboratory Animals. The program of the second Conference was intended to be complementary to that of the first. In 1966, the animals used for tests were considered. The 1969 conference focused on the tests themselves and their interpretation in relation to the toxicity or safety of the constituents, including additives and contaminants, of man's food for man. The contributions made by researchers at the conference included studies on the need for more biochemical information in food safety evaluation; the physiology of gastrointestinal absorption; renal function tests in laboratory animals; significance of age of test animals in food additive evaluation; aspects of protein metabolism relevant to food safety evaluation; and significance of organ-weight changes in food safety evaluation.

  • Vibrational Properties of Solids

    • 1st Edition
    • Gideon Gilat
    • English
    Methods in Computational Physics, Volume 15: Vibrational Properties of Solids explores the application of computational methods to delineate microscopic vibrational behavior. This book is composed of nine chapters that further illustrate the utility of these methods to ordered lattices, quantum solids, impurity modes, surface modes, and amorphous solids. The opening chapters present the basic theoretical models and their computational aspects for different solids of diverse chemical nature, together with some methods of automation and computation in the highly sophisticated experiments in inelastic scattering of neutrons. These topics are followed by a discussion on how group theoretical methods treated by computers can yield the proper symmetry assignments of phonon eigenvalues and eigenstates. Considerable chapters are devoted to the different applications of traditional lattice dynamics, each having its own computational ramification. Other chapters survey the properties of solids that mostly involve integrations over the Brillouin zone. The last chapter concerns the dynamic or time-dependent aspect of lattice dynamics, namely, the calculation of thermal and electric conductivities in some models of solids. This book is of great benefit to geoscientists, physicists, and mathematicians.

  • Efferent Organization and The Integration of Behavior

    • 1st Edition
    • Jack Maser
    • English
    Efferent Organization and the Integration of Behavior is a nine-chapter text that discusses the hypotheses and alternative conceptualizations of efferent mechanisms, as well as the neural basis of patterned movement. The opening chapters examine several behavioral categories, the neural mediation of movement, and the distinction between efferent response and efferent motor processes. These chapters also present a revised theory of the role of the motor system in physiological regulation and neural-metabolic integration in energy production for behavior. These topics are followed by considerable chapters devoted to efferent organization of specific brain sections, including the motor cortex, pyramidal system, globus pallidus, substantia nigra, diencephalon, hippocampus, and neocortex. This text also deals with the instrumental conditioning based on alimentary or food reinforcements. A chapter discusses the constraints on theoretical interpretations of neuroanatomical circuitry functions of noradrenergic and cholinergic brain systems. The concluding chapter describes the relationship between the motor integration systems of extrapyramidal structures and the motivational systems of limbic structures. This chapter also looks into the anatomical organization of self-stimulation and the microelectrode data, which delineate the response of single neurons to stimulation at hypothalamic self-stimulation sites.

  • Tropical Forests

    Botanical Dynamics, Speciation & Diversity
    • 1st Edition
    • Bozzano G Luisa
    • English
    Proceedings of a conference on Tropical Forests: Botanical Dynamics, Speciation and Diversity held at the University of Aarhus, Denmark, August 8*ba10, 1988.The increasing rate of destruction of the world's tropical forests gives grave cause for concern on several counts. In conservative terms, species are being lost at an incredible rate, many before they have even been described. In scientific terms, habitats, communities, and unique systems are lost before they can be studied and used to broaden our understanding of ecological processes in general.The meeting on which this book is based aimed to address two basic needs: to describe some of the marvellous biological treasures of tropical forests and to learn what they can tellus about processes in ecology, and to alert us all once again to the disaster which is overtaking this rich and varied environment.
