    Ballistic Missile and Aerospace Technology, Volume IV: Re-entry is a collection of manuscripts presented at the Sixth Symposium on Ballistic Missile and Aerospace Technology, held in Los Angeles, California, in August 1961. This book is organized into two parts encompassing nine chapters that highlight the re-entry vehicle design information and re-entry thermal protection and materials. Part I deals first with a parametric study on the effects of initial conditions and various mass and aerodynamic parameters on the dynamic motion of a typical re-entry vehicle. This parametric study specifically examines both spinning and non-spinning re-entry at high angles of attack. This part also demonstrates the degree of departure from thermodynamic equilibrium for the various chemical reactions along a typical streamtube to be expected under different flight conditions. This topic is followed by discussions on power-handling capability of antennas operating in the presence of plasmas; the mechanism of self-excited oscillations at transonic speeds; and the computation of three-dimensional steady supersonic flow fields. Part II presents a theoretical analysis of similarity paramaters of evaporative film cooling for blunt bodies. This part then explores the application of ultrasonics to ablation studies. The remaining chapters describe a self-contained, thermally protective mechanism, which is activated by a catalyst that operates within a composite material. These chapters also consider the developmental trends in aerospace materials.

  • Optical Waveguides

    • 1st Edition
    • N Kapany
    • English
    Optical Waveguides describes waveguide phenomena in classical optical terms. This book discusses mode propagation by using equivalent plane waves, polarization, rays, and intensity distributions. Comprised of seven chapters, this book starts with an overview of the history of optical waveguides with emphasis on the earliest studies of dielectric guides. This text then explores the theoretical treatment of guided waves in planar dielectric waveguides in terms of the characteristic modes of these structures. Other chapters consider the interferometric description of the coupling of a uniform beam of light into a thin film through the mechanism of frustrated total reflection. This book discusses as well the properties of the modes of fiber optical waveguides. The final chapter deals with the general properties of the characteristic TE wave (modes) of a symmetric slab guide by direct solution of the homogeneous Maxwell equations. Students of optics and physics, as well as electronic, optical, and communications engineers, will find this book useful.

  • Excited States V3

    • 1st Edition
    • Edward Lim
    • English
    Excited States, Volume 3 deals with excited states and covers topics ranging from two-photon molecular spectroscopy in liquids and gases to time evolution of excited molecular states. Product energy distributions in the dissociation of polyatomic molecules are also discussed, along with the mechanism of optical nuclear polarization in molecular crystals and vibronic interactions and luminescence in aromatic molecules with non-bonding electrons. Comprised of five chapters, this volume begins with a didactic treatment of the theory of simultaneous two-photon absorption spectroscopy from the point of view concerned primarily with molecular gases and liquids. The basic theoretical quantity is shown to be an absorption tensor, as contrasted with the absorption vector of one-photon spectroscopy. The next chapter considers the time evolution of a molecular system interacting with a photon wave packet. The theory is applied to handle photon scattering from several physical models for molecular level structure in excited electronic states of polyatomic molecules. The remaining chapters explore various polyatomic decomposition processes and the basic features governing the internal energy distribution of the fragments; optical nuclear polarization in molecular crystals and vibronic interactions; and luminescence in aromatic molecules with non-bonding electrons. This book should be of interest to chemists and molecular physicists.

  • Cardiac Muscle: The Regulation Of Excitation And Contraction

    • 1st Edition
    • Richard Nathan
    • English
    Cardiac Muscle: The Regulation of Excitation and Contraction is a 12-chapter text that covers the research studies on characterizing the ionic and molecular mechanisms that regulate excitation and contraction of cardiac muscle. This book describes first the ionic currents underlying diastolic depolarization and pacing of the heart. The discussions then shift to the mechanisms of action of calcium-channel antagonists; the regulation of calcium influx by indigenous factors, such as voltage- or calcium-mediated inactivation; the identification of fixed negative charges on the surface of the sarcolemma; and the regulation of gating and permeability of ion channels by these charges. These topics are followed by examining the molecular and ionic mechanisms that underlie the electrophysiologic actions of adrenergic and cholinergic neurotransmitters and peptide hormones. This text further explores the theoretical and experimental studies of the sodium-calcium exchange process, its stoichiometry, and how the exchanger might contribute to current flow during or after the action potential. Other chapters consider the mechanism of twitch and tonic tension regulation by cardiac glycosides and intracellular sodium and how toxic concentrations induce cardiac arrhythmias. A chapter highlights the identification of sarcolemmal binding sites for calcium, the likelihood that such binding or the release of calcium from the sarcoplasmic reticulum plays a role in the regulation of contraction and the release of calcium from the sarcoplasmic reticulum. The remaining chapters deal with the structural similarities among calcium-binding proteins of the contractile apparatus and the calcium channel, and the regulation of contraction by calcium-binding proteins. Physiologists, pathophysiologists, clinicians, researchers, and students who are interested in heart’s function will find this book invaluable.

    Isolation, Characterization, and Utilization of T Lymphocyte Clones is a summary of information regarding T lymphocyte clones, including their usefulness. Organized into nine parts, the book begins with discussions on the soluble factors that can influence the growth of cloned T cells and the utilization of T cell hybridomas for analysis of T cell functions, emphasizing the biochemical and functional properties of helper and suppressor factors. The book then looks into the analysis of T cell clones and hybridomas using techniques of somatic cell genetics. The clonal analysis by limiting dilution, the characteristics of murine T cell clones reactive with alloantigens and soluble antigens, and the human T cell clones are described as well. This volume is valuable to those interested in the field of cloning of immunocompetent T cells.

  • Qualitative Analysis of Physical Problems

    • 1st Edition
    • M Gitterman
    • English
    Qualitative Analysis of Physical Problems reviews the essential features of all the main approaches used for the qualitative analysis of physical problems and demonstrates their application to problems from a wide variety of fields. Topics covered include model construction, dimensional analysis, symmetry, and the method of the small parameter. This book consists of six chapters and begins by looking at various approaches for the construction of models, along with nontrivial applications of dimensional analysis to some typical model systems. The following chapters focus on the application of symmetry to the microscopic and macroscopic properties of systems; the implications of analyticity and occurrence of singularities; and some methods of deriving the magnitude of the solutions (that is, approximate numerical values) for problems that usually cannot be solved exactly in closed form. The final chapter demonstrates the use of qualitative analysis to address the problem of second harmonic generation in nonlinear optics. This monograph will be a useful resource for graduate students, experimental and theoretical physicists, chemists, engineers, college and high school teachers, and those who are interested in obtaining a general perspective of modern physics.
