    Gamma-Ray Spectrometry of Rocks: Methods in Geochemistry and Geophysics provides information pertinent to the fundamental aspects of the gamma-ray spectrometry of rocks. This book discusses the increasing interest in using gamma spectrometry in the search for uranium ore. Organized into seven chapters, this book begins with an overview of the approximate frequency and wave length of electromagnetic radiations. This text then examines the quantitative detection of X and gamma photons, which is based upon their interactions with matter. Other chapters consider the inorganic scintillation crystals as the most favorable detectors due to its requirement of a high intrinsic efficiency. This book discusses as well the shape of the spectrum of a monoenergetic gamma-ray beam, which is dependent on the photon energy. The final chapter deals with the determination of the abundances of natural radioisotopes and their stable end products in a rock or mineral. This book is a valuable resource for radiological health physicists, chemists, geochemists, and exploration geologists.

    Advances in Endogenous and Exogenous Opioids contains the proceedings of the International Narcotic Research Conference (Satellite Symposium of the 8th International Congress of Pharmacology) held in Kyoto, Japan on July 26-30, 1981. The conference provided a forum for discussing advances that have been made in the understanding of endogenous and exogenous opioids and tackled a wide array of topics ranging from novel opiate binding sites selective for benzomorphan drugs to the purification of opioid receptors and sequellae of receptor binding. Comprised of 156 chapters, this book begins with an analysis of the interaction of opioid peptides and alkaloid opiates with mu-, delta-, and kappa-binding sites. The reader is then systematically introduced to biochemical evidence for kappa and sigma opiate receptors; the action of morphine and oxymorphone as partial agonists on the field-stimulated rat vas deferens; mechanisms of supersensitivity in the enkephalinergic system; and properties of the solubilized opiate receptor from human placenta. Subsequent chapters explore the biosynthesis of opioid peptides as well as their localization, release, and degradation; physiological and pharmacological actions of opioids; and the use of analgesia in acupuncture. Results of behavioral and clinical studies of endogenous and exogenous opioids are also presented, and the structure-activity relationships of opioids are examined. This monograph will be of interest to students, practitioners, and researchers in the fields of psychiatry and pharmacology.

  • Meeting the Pump Users Needs

    The Proceedings of the 12th International Pump Technical Conference
    • 1st Edition

    • English
    Meeting the Pump Users Needs is a documentation of the 12th International Pump Technical Conference. Pump makers have always understood that their equipment provides an essential service to the pump users. Pumps have been designed and built to satisfy the needs of the user. The main thrust of this book is to share between users, specifiers, and makers their knowledge and experiences leading to better understanding of what the user needs now and would like for the future, and what the designer/maker can provide now and may be able to offer for the future. This book also describes an unusual method of calculating a head generated across a multistage pump when the impeller diameters are changed. The method leads to significantly larger calculated changes of head than predicted from the conventional affinity law approach. This text is a useful reference and source of information for engineering students and those conducting research on pump manufacturing.

  • The Structure of the Earth's Crust

    Based on Seismic Data
    • 1st Edition
    • Stephan Mueller
    • English
    Developments in Geotectonics 8: The Structure of the Earth's Crust Based on Seismic Data covers the papers presented at an International Upper Mantle Committee (lUMC) symposium called ""Crustal Structure Based on Seismic Data"", held on July 30-31, 1971. The book focuses on the structure, composition, and characteristics of the earth's crust. The selection first offers information on the crustal structure of Central and Southeastern Europe by data of explosion seismology; structure of the earth's crust on the territory of the U.S.S.R.; and seismic studies of low-velocity layers and horizontal inhomogeneities within the crust and upper mantle on the territory of the U.S.S.R. The text also takes a look at the deep seismic investigations in the Baikal rift zone and crust of the arctic seas of Eurasia. Discussions focus on peculiarities of crustal structure, structure of the uppermost mantle, and method of investigation. The publication takes a look at the crustal structure of Japan as derived from explosion seismic data; crustal structure in the Matsushiro earthquake swarm area; and Soviet seismic studies of the earth's crust in the Pacific Ocean during the International Upper Mantle Project. The selection is a dependable source of information for readers interested in the structure of the earth's crust.

    Atlas of the Ultrastructure of Diseased Human Muscle provides a general view of the ultrastructure of normal and diseased human muscle. This book contains five chapters that illustrate the changes that take place in common pathological conditions and outline the patterns of change, which occur in particular diseases. Chapter 1 describes the ultrastructure of normal striated muscle and the extra-ocular and cardiac muscle. This chapter also deals with skeletal and cardiac muscle of the human fetus. Chapter 2 examines the changes in the ultrastructure of muscle fibers, including changes in myofibrils, mitochondria, lipid bodies, plasma, and basement membranes. Chapters 3 and 4 evaluate the changes in blood capillaries, interstitial tissue of muscle, nerves, motor end plates, and muscle spindles. Chapter 5 discusses the ultrastructural changes in various muscle diseases, such as denervation atrophy of muscle, muscular dystrophies, polymyositis, and congenital myopathies.

    • English
    Materials Data for Cyclic Loading, Part D: Aluminium and Titanium Alloys presents materials data for cyclic loading which provide the basis for materials assessment by direct comparison of data or characteristic values and for estimating the crack initiation lives of aluminum and titanium alloys under constant and variable amplitude loading. The data include stress-strain curves, strain life curves, and mean stress parameter life curves for cyclic loading. Each data sheet takes up a maximum of four pages. The first page gives a description of the material and testing procedure. The chemical composition is always given in weight percent and corresponds to the values given in the literature referred to. The second and third pages show the diagrams for: stress-strain curves for monotonic and cyclic loading; strain life curve;, and mean stress (damage) parameter life curve according to the parameter of Smith, Watson and Topper. Unless indicated otherwise in the plots, the experiments were carried out at room temperature in laboratory air. The diagrams for the stress-strain relationships contain at the most three curves, one for monotonic loading and two for cyclic loading, the latter being evaluated from incremental step tests and constant amplitude tests. All three curves can be described approximately by an analytical function. This book will be of interest to materials scientists.

  • Quadrupole Mass Spectrometry and Its Applications

    • 1st Edition
    • Peter H. Dawson
    • English
    Quadrupole Mass Spectrometry and Its Applications provides a comprehensive discussion of quadrupoles and their applications. It proceeds from a general explanation of the action of radiofrequency quadrupole fields to the description of their utilization in mass analyzers—such as the quadrupole mass filter, the monopole, the three-dimensional quadrupole ion trap, and various time-of-flight spectrometers—and finally to the characteristic applications of quadrupoles. A multi-author format has been adopted to provide broader-than-usual viewpoint in the book. The book begins by explaining the principles of operation of quadrupole devices. These include ion trajectories and computer simulations of performance; analytical theory; numerical methods of calculation of performance, including the recently developed application of phase-space dynamics; and fringing fields and other field imperfections. Subsequent chapters provide design and performance evaluations of the mass filter, the monopole, ion traps, and time-of-flight instruments; and describe areas of application where quadrupole devices have made the greatest impact because of their particular advantages and disadvantages.
