  • Frequency Response Testing in Nuclear Reactors

    • 1st Edition
    • T Kerlin
    • English
    Frequency Response Testing in Nuclear Reactors presents the optimum testing procedures for measurements in power reactors. This eight-chapter book emphasizes the determination of the system frequency response using nonsinusoidal input perturbations, which are useful since normal power reactor hardware can be used. This text deals first with the mathematical aspects of frequency response testing, with a particular emphasis on numerical Fourier transformations using analog or digital equipment. The subsequent chapters examine the important signals for use in frequency responses tests and the analysis of these signals using analog and digital computing equipment. The discussion then shifts to the frequency response functions that describe nuclear reactor dynamics. This topic is followed by a presentation of techniques for extracting useful information from test results. A chapter highlights the most common control-rod drive mechanisms to assess their suitability for dynamics testing. The concluding chapter provides a brief summary of significant experiences with dynamics tests in nuclear reactors. Scientists, researchers, and workers in the field of nuclear reactors and related subjects will find this book invaluable.

    Science and Technology of Rare Earth Materials reviews the important aspects of the science and technology of rare earth materials, covering the entire spectrum from occurrence to extraction and purification, phase relationships, electronic structure, and applications. This book is organized into five sections encompassing 19 chapters. The occurrence, extraction, and production of rare earths are discussed in the first section, followed by purification methods employed for rare earths, together with the role of impurities on their behavior. The phase relations among the rare earth alloys, including a particular reference to the technologically important rare earth-cobalt alloys, and phase relations among the rare earth oxides are considered in the second section. The succeeding two sections focus on studies of the electronic structure of rare earth materials, with emphasis on the use of nuclear magnetic resonance and Mössbauer spectroscopy. Theoretical conceptions are set forth as well as the effect of crystal fields and valence fluctuations on the properties of rare earth systems. The final section describes some of the extensive current uses of rare earth materials such as in the steel industry and in permanent magnets, as well as emerging applications in catalysis, hydrogen storage, ferroelectrics, and fast ion conductors.

  • Control Mechanisms in Developmental Processes

    • 1st Edition
    • Michael Locke
    • English
    Control Mechanisms in Developmental Processes covers the proceedings of the 1967 26th Symposium of The Society for Developmental Biology, held in La Jolla, California. This book is divided into three parts encompassing 10 chapters that summarize the role of cytoplasmic units and the nucleus in developmental processes and the regulatory mechanisms. The opening part of the book describes the chemical changes during the development of plastids in leaves of higher plants. The book goes on discussing the nuclear and cytoplasmic controls in Neurospora morphology. This compilation also examines the aspects of development, growth, and control in the basal bodies and flagella of Chlamydomonas reinhardii. The second part describes genetic systems in plants that serve to initiate or program the sequence in plant development and the life cycle of hybrids between somatic cells of different species. A chapter discusses the genetic basis of higher plant morphogenesis by analysis of the differences between genotypes that differ from each other with respect to a single gene having a pronounced and highly specific effect upon form. A discussion on the activation of protein synthesis upon fertilization and early development of animal eggs to the biochemical basis of the determination process is also included. The concluding part deals with the differentiation of erythroid cells; the induction of hemoglobin synthesis; the regulation of heme and globin synthesis; and the role of heme in the synthesis and assembly of hemoglobin. This part also describes the differentiation of cells to the point where they can perform the various types of immunological reactions. This book is an invaluable source for developmental biologists and researchers.

  • Humoral Control of Growth And Differentiation

    Vertebrate Regulatory Factors
    • 1st Edition
    • Joseph Lobue
    • English
    Humoral Control of Growth and Differentiation, Volume I: Vertebrate Regulatory Factors is a part of two-volume work that introduces the reader to humoral control of growth and differentiation in vertebrates. This volume gives emphasis on chemical messengers, which have received relatively little attention in standard treatises on endocrine physiology for a number of reasons. Organized into three parts, this book begins with the physiological significance of chalones. This class of hormones is intimately associated with mitotic homeostasis as inhibitors of cell division. The book then looks into the aspects of blood cell formation and release, as well as the humoral control of organs and tissue growth. This volume also includes chapters discussing the humoral changes occurring in diseases of the blood and other pathologic states. The humoral factors influencing lymphocyte proliferation in culture are also explained. Moreover, this volume examines the effects of the more orthodox hormones upon skeletal growth and regeneration.

    • 1st Edition
    • Albert Sparks
    • English
    Invertebrate Pathology Noncommunicable Diseases discusses the taxonomic and phylogenetic aspects of invertebrate pathology, beginning with protozoans and progressing through the ascending taxonomic order to the chordates. The book is organized into seven chapters that cover the death and postmortem change; reaction to injury and wound repair; the physical and chemical injuries; the effects of venoms and biotoxins; the effects of ionizing radiation; and tumors and tumor-like growths. The opening chapter describes stages of events in death: necrosis; somatic death; gross and histological postmortem changes; and cellular depression and degeneration. The following chapter discusses the inflammatory response, called wound repair, to injury in invertebrates. This text describes the processes that occur after injury in many invertebrates and covers the general principles of physical, chemical, and biological injuries. Discussions on the effects of trauma, pressure and temperature changes, poisons, pesticides, detergents, venoms, biotoxins, and toxigenic algae are included. The book further examines the effects of ionizing radiation both on vertebrates and invertebrates, such as beta particles, gamma and X-rays, and neutrons. The concluding chapter describes the structures of tumor in invertebrates, focusing on hyperplasia or unusual proliferation of typical cellular components, in response to injury or parasitic invasion. With an ultimate objective to stimulate an acceleration of research effort in invertebrate pathology, the book is an invaluable source for invertebrate pathologists, immunologists, and parasitologists.
