  • Mechanisms and Regulation of Carbohydrate Transport in Bacteria

    • 1st Edition
    • Milton H. Saier
    • English
    Mechanisms and Regulation of Carbohydrate Transport in Bacteria reviews the developments in the study of the mechanisms and regulation of carbohydrate transport in prokaryotic organisms. The book presents the progress made in the understanding of transport and regulation of carbohydrates in bacteria in the molecular level. Aspects on the important structural and topographical features of several sugar permeases in Escherichia coli are elucidated; the energy-coupling processes are clearly delineated for most (but not all) types of bacterial carbohydrate permease systems; and mechanistic details of the translocation processes are proposed. Molecular biologists, microbial biochemists, and cell biologists will find the book a good source of information.

    • English
    Laminar Flow Forced Convection in Ducts is a sourcebook for compact heat exchanger analytical data. This book describes the analytical solutions for laminar fluid flow and forced convection heat transfer in circular and noncircular pipes, including applicable differential equations and boundary conditions involving velocity and temperature problems of fluid flow. The book also discusses fluid flow—how much power is required to pump fluids through the heat exchanger, as well as the heat transfer—the determination of q" distribution, and the temperature of fluid and walls. The text also analyzes the coolant or heat transfer fluid flows in a nuclear power reactor composed of a bundle of circular section fuel rods located inside a round tube. R.A. Axford addresses fluid flow and heat transfers results for the rod bundle geometry in "Heat Transfer in Rod Bundles." The book also provides an overview and guidelines that can be used for the designer and the applied mathematician. This book is suitable for engineers working in electronics, aerospace, instrumentation, and biomechanics that use cooling or heating exchanges or solar collection systems.

  • Speech and Language

    Advances in Basic Research and Practice
    • 1st Edition
    • Volume 11
    • Norman J. Lass
    • English
    Speech and Language: Advances in Basic Research and Practice, Volume 11 contains articles that discuss a wide range of topics on speech and language processes and pathologies. This volume is comprised of six contributions on a wide variety of topics on speech and language. The book begins with an examination of approaches to aphasia diagnostics from both a medical and nonmedical perspective. Subsequent chapters cover topics on acoustic-phonetic descriptions of speech production in speakers with cleft palate and other velopharyngeal disorders; the role of infant vocalizations as they relate to subsequent speech and language development; pitch phenomena and applications in electrolarynx speech; and practical applications of neuroanatomy. The final chapter presents the employment of studies of temporal coordination to understand the development of motor control in speech and to provide a basis for testing theories on the development of speech as a motor skill. Linguists, speech pathologists, and researchers on language development will find the book very insightful and informative.

  • Enzyme Catalysis and Control

    • 1st Edition
    • Volume 24
    • Marlene Deluca + 2 more
    • English
    Current Topics in Cellular Regulation: Volume 24, Enzyme Catalysis and Control is a compendium of papers that discusses phosphoryl transfer reactions, the role of water on the free energy of hydrolysis of pyrophosphate, and the hormonal actions of vitamin D. Other papers describe the regulation lipid metabolism by a lipid-carrying protein, the GABA, and taurine enzymes in mammalian brain. One paper examines the role of vitamin D in the metabolism of cells, as well as in the whole animal. Upon absorption in the body, the vitamin undergoes various metabolic transformations before interacting with specific receptors, and then inducting the genome in the target tissues to generate biological and hormonal responses. Another paper notes the possibility of a genetic defect in cancer cells that results in the abnormal accumulation of sterol carrier protein (SCP) and cholesterol in vivo; and also in the inability to maintain levels of SCP or cholesterol in vitro. One paper shows that tartrate, or other organic acids, secreted into the medium by the penicillia keeps the pH in an optimal range for acid protease degradation of proteins and glycoproteins. This mechanism helps the fungus to survive in a nutrient environment (which is unbalanced with respect to an optimum C/N ratio and at a pH unfavorable to many bacteria and other life forms). Another paper proposes a model for the modulation of ATP synthetase activities and medium exchange reactions by energy input, substrate concentration, or others that affect the microenvironment of the enzyme under certain conditions. The compendium will prove beneficial to molecular biologists, general biologists, microbiologists, and biochemists.

  • Bacteriocins of Lactic Acid Bacteria

    • Dallas G. Hoover + 1 more
    • English
    Bacteriocins of Lactic Acid Bacteria is based on the 1990 Annual Meeting of the Institute of Food Technologists held in Dallas, Texas. It describes a number of well-characterized bacteriocins and, where possible, discusses practical applications for those that have been defined thus far from the lactic acid bacteria. The book begins with an introductory overview of naturally occurring antibacterial compounds. This is followed by discussions of methods of detecting bacteriocins and biochemical procedures for extraction and purification; genetics and cellular regulation of bacteriocins; bacteriocins based on the genera of lactic acid bacteria Lactococcus, Lactobacillus, Pediococcus, and Leuconostoc, and related bacteria such as Carnobacterium and Propionibacterium; and the regulatory and political aspects for commercial use of these substances. The final chapter sets out the prognosis for the future of this dynamic area. The information contained in this book should benefit those with interest in the potential for industrial use of bacteriocins as preservative ingredients. Anyone interested in lactic acid bacteria or the biosynthesis, regulation, and mechanisms of inhibition of these proteinaceous compounds will also appreciate the material presented. These include food scientists, microbiologists, food processors and product physiologists, food toxicologists, and food and personal product regulators.
