  • Old and New Problems in Elementary Particles

    • 1st Edition
    • G Puppi
    • English
    Old and New Problems in Elementary Particles provides information pertinent to elementary-particle physics. This book examines the types of problems facing high-energy physicists. Comprised of 20 chapters, this book starts with an overview of the fundamental properties of Dirac poles, with emphasis on the spin, the electric-dipole moment, and the mass. This text then examines the applications of supergain antenna, which is an interesting cautionary model against an oversimplified application of the notion of indeterminacy. Other chapters explain the uninhibited adoption of a uniform and natural experimental definition of resonance or particle with respect to hadrons. This book illustrates as well how insight into strong-interaction dynamics may be improved by a precise definition of the particle-resonance concept. The final chapter deals with the derivation of the Alder–Weisberger relation, which links the ratio of the two weak coupling constants of the nucleon with an integral over pion absorption cross-sections. Physicists and researchers will find this book useful.

  • Quantum Theory and Gravitation

    • 1st Edition
    • A Marlow
    • English
    Quantum Theory and Gravitation provides information pertinent to quantum theory and general relativity. This book defines the problem areas and presents specific solutions to problems in relativity or quantum theory. Organized into 17 chapters, this book starts with an overview of the concept of pregeometry wherein the geometry of space and space time are based. This text then explores the restriction to real amplitude in photon polarization experiment, which appears in the fact that the elliptical polarizations are not included as possibilities. Other chapters consider the primary role that space-time models play in the expression of physical theories. This book discusses as well the basic structure of an axiomatic model for a fully relativistic quantum theory, which consists of four axioms imposed on an operational quantum logical universe of discourse. The final chapter describes the relationships between certain areas of mathematics and the developments in theoretical physics. Physicists, mathematicians, and researchers will find this book useful.

    Additives for Plastics: Volume 1, State of the Art summarizes the state of the art about additives for plastics, including coupling agents for fillers and plasticizers, as well as colorants, silicas, cellulose fiber, whiskers, and microfibers. Stabilizers for weather, fungal, and heat resistance and resistance to ultraviolet radiation are also considered. This volume is comprised of 13 chapters; the first of which introduces the reader to nonreinforcing fillers such as carbon black, wood flour, alpha cellulose, calcium carbonate, and natural and synthetic silicates. The discussion then turns to synthetic and naturally occurring silicas, short cellulose fibers for reinforcing polymers, and asbestiform fillers. Whiskers and microfibers are the subject of the subsequent chapter, with emphasis on their differences and similarities, application in various plastics, and prospects. Silane and nonsilane coupling agents, nonfiller additives, plasticizers, biocides, and heat stabilizers are also examined. This volume also evaluates rutile titanium dioxide and other white pigments with regard to the opacification and coloring of plastics.

The structure and function of the individual proteins of the contractile apparatus and their organization as evidenced by light and electron microscopy and by X-ray analysis are also covered. Chapter 4 deals with collagen, an important constituent of the extracellular connective tissues in animals and one of the most abundant proteins. This chapter emphasizes the biosynthesis of collagen fibrils. Organic chemists and researchers, teachers and undergraduate students will find this book invaluable.

  • Metabolic Inhibitors V1

    A Comprehensive Treatise
    • 1st Edition
    • R Hochster
    • English
    Metabolic Inhibitors: A Comprehensive Treatise, Volume I focuses on the properties of inhibitors of metabolic processes or enzyme systems. The book explores a wide range of substances that interfere with (and usually retard) metabolic and enzymic processes, emphasizing the inhibitor rather than the metabolic or enzymic system that is affected. Organized into 15 chapters, this volume begins with a historical overview of research on the mode of action of biological inhibitors, touching on the principle of competitive inhibition by structural analogues. The book then turns to the concept of a competitive enzymic relationship by growth inhibitory analogues and their corresponding amino acids; the metabolic inhibitory effects of polypeptides and proteins; and the use of pentoses as analogues in carbohydrate metabolism. The reader is also introduced to the metabolic inhibitory effects of fatty acids; the intermediary metabolism of phospholipids; and the inhibition of purine and pyrimidine analogues. The remaining chapters discuss the role of nucleic acids and nucleoproteins in the regulation of cellular metabolism and the inhibition of amino acid decarboxylases, cholesterol, and steroid biosynthesis. This book will be of value to biochemists, advanced students, medical research workers, and research workers in the various fields of biological chemistry, as well as those working in the microbiological, botanical, and other agricultural fields.
