    • Inglés
    Advances in Astronomy and Astrophysics, Volume 3 is a collection of papers that describes the elements found in the solar atmosphere, Fourier transforms, internal structure of the stars, and apsidal motions. Two papers discuss the spectral analysis of solar flares and a survey of modern cosmology. One paper discusses the solar abundance of particular elements such as iron, sodium, potassium, zinc, gallium, strontium. The loss of heavier elements from the upper layers of the solar atmosphere depends on the atomic number: the heavier the atom the greater the amount of depletion. Another paper describes a method to determine the elements of an eclipsing binary system by defining the characteristic functions of the eclipse derived from some integral transforms of the ascending and descending parts in minima of the light curve. One paper compares the general physical theory of self-gravitating gas spheres and of thermonuclear processes with certain phenomena present in close binary systems. One paper notes that the estimates of electron density made by various methods at different flares (solar) and the resulting optical thickness of flares yield values within a wide range. The differences observed in optical thickness are due to various presuppositions on the broadening mechanism of the Balmer lines. The collection is suitable for astronomers, geochemists, astro-physicists, and scientists whose works involve cosmology.

    • Inglés
    The Theory of Neutron Slowing Down in Nuclear Reactors focuses on one facet of nuclear reactor design: the slowing down (or moderation) of neutrons from the high energies with which they are born in fission to the energies at which they are ultimately absorbed. In conjunction with the study of neutron moderation, calculations of reactor criticality are presented. A mathematical description of the slowing-down process is given, with particular emphasis on the problems encountered in the design of thermal reactors. This volume is comprised of four chapters and begins by considering the problems of neutron moderation and their importance in all types of reactors. An asymptotic reactor model is described, and the calculation of the elastic scattering frequency is explained. Subsequent chapters focus on the process of slowing down in finite and infinite medium by analyzing capture by individual resonances; resonance integrals in heterogeneous systems; the slowing-down kernels; the spherical harmonics method; statistical methods; and small source theory. The final chapter presents numerical solutions of the Boltzmann equation and covers topics such as the multigroup approach, group constants, and solution of the multigroup equations. This book will be a useful resource for nuclear physicists and engineers.

  • Wave Propagation and Group Velocity

    • Inglés
    Wave Propagation and Group Velocity contains papers on group velocity which were published during the First World War and are missing in many libraries. It introduces three different definitions of velocities: the group velocity of Lord Rayleigh, the signal velocity of Sommerfeld, and the velocity of energy transfer, which yields the rate of energy flow through a continuous wave and is strongly related to the characteristic impedance. These three velocities are identical for nonabsorbing media, but they differ considerably in an absorption band. Some examples are discussed in the last chapter dealing with guided waves, and many other cases of application of these definitions are quoted. These problems have come again into the foreground, in connection with the propagation of radio signals and radar. Reflection in the Heaviside layers requires a real knowledge of all these different definitions. Group velocity also plays a very important role in wave mechanics and corresponds to the speed of a particle. The present book should be very useful to physicists and radio engineers and should give them a good basis for new discussions and applications.

    Annals of the International Geophysical Year, Volume 28: Tables of IGC Cosmic Ray Data, Part III contains tabulations of International Geophysical Cooperation's cosmic ray activity data. This book includes lists of stations and investigators from whom further information on the cosmic ray apparatus can be obtained. In order to prepare the data on the following pages for publication, the data are first put on punched cards and then checked for correctness essentially by repunching, thus minimizing errors of transcription and also facilitate some computations which have been made with some of the data. Tabulating machines are then used to print the data on standard forms and the data are photographed for reproduction. As a further insurance against errors, carbon copies of the data sheets are sent to all investigators to be checked. The data marked as verified in the table of contents have been returned to the data center and the corrections made. This book will prove useful to geophysical researchers.

    Elementary Classical Hydrodynamics deals with the fundamental principles of elementary classical hydrodynamics, with emphasis on the mechanics of inviscid fluids. Topics covered by this book include direct use of the equations of hydrodynamics, potential flows, two-dimensional fluid motion, waves in liquids, and compressible flows. Some general theorems such as Bernoulli's equation are also considered. This book is comprised of six chapters and begins by introducing the reader to the fundamental principles of fluid hydrodynamics, with emphasis on ways of studying the motion of a fluid. Basic concepts and quantities such as viscosity, density, and pressure, are considered, along with hydrostatics and the equation of motion. The discussion then turns to Bernoulli's equation, the motion of a small element of fluid, velocity potential, and the kinetic energy of a uniform incompressible fluid. The chapters that follow explore two-dimensional fluid motion; a uniform inviscid, incompressible liquid having a free surface and upon which the only body force acting is uniform gravity; and a compressible gas with undisturbed uniform pressure and density, paying particular attention to the propagation and reflection of sound waves. This book is intended as an elementary introduction to the mechanics of inviscid fluids for first and second year undergraduates.

    The Use of Locks in Physical Crime Prevention aims to present the minimum necessary material that will enable the proper use of locks as security devices. The lock is the most widely used security device. Wherever people have an interest in securing their persons or property against intruders, some sort of locking devices have been developed and used. The effectiveness of any locking system depends on a combination of interrelated factors that are involved in the design, manufacture, installation, and maintenance of the system. A security specialist needs to understand the weaknesses and strengths of the various systems, and know how each must be used to achieve maximum benefit from its application. This goal requires a thorough understanding of the inner workings of the various types of locks, which this book presents. This book is presented in layman's language and does not require an extensive background in security. However, the technological detail contained in this book will be of use to professionals in the field.

    • Inglés
    Topics in Atomic Collision Theory originated in a course of graduate lectures given at the University of Colorado and at University College in London. It is recommended for students in physics and related fields who are interested in the application of quantum scattering theory to low-energy atomic collision phenomena. No attention is given to the electromagnetic, nuclear, or elementary particle domains. The book is organized into three parts: static field scattering, electron-atom collisions, and atom-atom collisions. These are in the order of increasing physical complexity and hence necessarily in the order of decreasing mathematical tractability. The topics and methods selected were those which contributed most significantly to the understanding of the physics and the calculation of reliable cross sections. The attempt has been made to treat each of the sections in a complete and self-contained manner. The limited scope of this book has unfortunately made it necessary to omit discussion of many promising methods.

  • Dimensional Analysis and Group Theory in Astrophysics

    • Rudolf Kurth
    • Inglés
    Dimensional Analysis and Group Theory in Astrophysics describes how dimensional analysis, refined by mathematical regularity hypotheses, can be applied to purely qualitative physical assumptions. The book focuses on the continuous spectral of the stars and the mass-luminosity relationship. The text discusses the technique of dimensional analysis, covering both relativistic phenomena and the stellar systems. The book also explains the fundamental conclusion of dimensional analysis, wherein the unknown functions shall be given certain specified forms. The Wien and Stefan-Boltzmann Laws can be significant in the systematic application of dimensional analysis to the physics of a single star. The text also discusses group-theoretical reduction of ordinary differential equations and the reductions of the differential equations of stellar structure. The structure of a stellar envelope requires three hypotheses: (1) thermo-nuclear reactions as source of energy of stellar; (2) thermo-nuclear reactions occur at the star's core; and (3) that an envelope surrounding the core exists where no radiation is generated. To complete the model of a star, the investigator should have further assumptions such as the pressure is made-up of gas, radiation, or both. The book can prove helpful for astronomers, astro-physicists, cosmologists, and students of general physics.

    • Inglés
    Some Problems of Chemical Kinetics and Reactivity discusses two types of explosion in detail. These two types are the thermal and chain explosion. Points are also given in the book about thermal theory on a quantitative basis. The book explains that the science of combustion develops as a special branch of chemical kinetics. The text also covers the chain ignition concept. Such concept shows that phosphorus would not ignite below some critical oxygen pressure and no traces of reaction could be detected under such condition. Another type of concept discussed in the book is the branched chain reactions. The book proves that the existence of limit phenomenon determines the practicability of using nuclear energy. Factors such as pressure, density, temperature, and vessel dimension transform inert condition to violent reaction. Formulas and computations to prove the concepts mentioned are provided in the book. The book will provide valuable insight to nuclear physicists, scientists, students, and researchers.

    Advances in Biological and Medical Physics, Volume VIII is a collection of papers that deals with chemical elements of blood, neutron activation analysis, and low level gamma-ray scintillation spectrometry. One paper describes the analysis of a large number of chemical elements in a single sample of human blood serum that includes the mean values gathered for 66 chemical elements. Another paper reviews the application of neutron activation analysis to biological and medical research, particularly in the detection and quantitation of trace elements in biological tissues. Some papers discuss the use of heavy ions in molecular and cellular radiobiology, the physics of space radiation, and carcinogenesis mechanisms. One paper discusses the radio-biological consequences of the ionizing radiation on a biological system that depends on the spatial distribution of the energy the system absorbs. The paper notes that the efficiency of heavy ions to inactivate dried enzymes kept at various constant temperatures during the exposure differs significantly from results obtained from that of sparsely ionizing radiations. Results gathered from comparisons of model and experiments, show that indirect energy transfers, such as those made by intermediary free radicals or other secondary reaction products, can play a role in carcinogenesis. The collection can prove beneficial for biochemists, micro-biologists, cellular researchers, and academicians involved in medical physics, radiological physics, or in the study of cellular biology and oncology.
