  • Intracellular Transport

    • 1st Edition
    • Katherine Brehme Warren
    • English
    Intracellular Transport, Volume 5 brings together a seemingly disparate group of scientists who offer their perspectives on the processes of and mechanisms underlying intracellular transport. Organized into 14 chapters, this volume begins with a review of some of the viewpoints about membrane structure and the unit membrane concept, including the so-called pauci-molecular theory of cell membrane structure advanced by Danielli and Davson. The next chapters focus on intracellular potentials, the localization of adenine nucleoside phosphatase activity, pinocytosis in amoeba, the brush border of cells, and the transport of gamma-aminobutyric acid. The reader is also introduced to pattern and rhythm; diffusion and reaction coupling; compartmental analysis and residence time distributions; and parametric pumping. The remaining chapters explore intracellular transport fluxes; theoretical aspects of permeability transport; rotating helices and contractile mechanisms; and the movements of cell membranes. This book is a valuable source of information for cellular biologists concerned with nature's evolved processing plants and engineers involved in the analysis and design of chemical processing plants.

  • Heat and Concentration Waves

    Analysis and Application
    • 1st Edition
    • G Turner
    • English
    Heat and Concentration Waves: Analysis and Applications describes the behavior of a limited class of waves of temperature or concentration that travels in a continuous medium, which itself is moving. This book is organized into nine chapters that discuss wave equations as solutions to linear differential equations. After briefly dealing with the fundamentals of waves and pulsed, this book goes on discussing the effect of introducing either an impulse or a steady source into a stream of uniform velocity or the so-called one-dimensional flow. The following chapters present some simplest basic equations for parameter determination in a flowing medium. These chapters also describe the pulses at an ideal boundary and the behavior of sine waves at such boundary, including the concept of reflections and the ease with which sine waves overcome the problems of incorporating boundary conditions into an experimental determination. This text further examines the behavior of reservoir phases under time-varying temperature or concentration. A chapter focuses on high-precision experimental measurements of sine waves. The concluding chapter outlines the computational processes, with emphasis on the estimation of experimental errors because of their effect on the reliability of parameter determination. Topics covered in the supplementary texts include the transformation of variables; the evaluation of important integrals; the normal distribution curve; aspects of the Laplace transform; some forms of transport equation common to both heat and mass transfer processes; and the interference of waves. This book will be of value to physical chemists, chemical and petroleum reservoir engineers, process metallurgists, physiologists, hydrologists, and soil scientists.

  • Radar Signals

    An Introduction to Theory and Application
    • 1st Edition
    • Charles Cook
    • English
    Radar Signals: An Introduction to Theory and Application introduces the reader to the basic theory and application of radar signals that are designated as large time-bandwidth or pulse-compression waveforms. Topics covered include matched filtering and pulse compression; optimum predetection processing; the radar ambiguity function; and the linear frequency modulation waveform and matched filter. Parameter estimation and discrete coded waveforms are also discussed, along with the effects of distortion on matched-filter signals. This book is comprised of 14 chapters and begins with an overview of the concepts and techniques of pulse compression matched filtering, with emphasis on coding source and decoding device. The discussion then turns to the derivation of the matched-filter properties in order to maximize the signal-to-noise ratio; analysis of radar ambiguity function using the principle of stationary phase; parameter estimation and the method of maximum likelihood; and measurement accuracies of matched-filter radar signals. Waveform design criteria for multiple and dense target environments are also considered. The final chapter describes a number of techniques for designing microwave dispersive delays. This monograph will be a useful resource for graduate students and practicing engineers in the field of radar system engineering.

  • Trace Elements in Human and Animal Nutrition

    • 4th Edition
    • E Underwood
    • English
    Trace Elements in Human and Animal Nutrition, Fourth Edition, explores the physiological roles of trace elements in human and animal nutrition. It looks at the needs, tolerances, and interactions of trace elements with each other and with other nutrients and compounds, and it explores how deficient, toxic, or imbalanced intakes of such elements lead to biochemical and pathological changes. It also describes ways of diagnosing and addressing such aberrant intakes of trace elements, along with their principal sources. Organized into 20 chapters, this volume begins with an overview of the nature of trace elements and their mode of action, including iron, copper, molybdenum, cobalt, nickel, manganese, zinc, cadmium, chromium, iodine, selenium, fluorine, mercury, vanadium, silicon, lead, and arsenic. It then discusses the presence of these elements in animal tissues and fluids, along with their metabolism, functions, and toxicity. It also considers other elements, such as aluminum, antimony, barium, boron, bromine, germanium, lithium, rubidium, silver, strontium, tin, titanium, and zirconium. The book concludes with an analysis of the interrelationships among soil, plants, and animals. This book should be a valuable resource for students and chemists.

  • Gradient Index Optics

    • 1st Edition
    • Erich Merchand
    • English
    Gradient Index Optics deals with the application of gradients in optical systems of classical types: gradient index lenses. The emphasis is on the theory and practice related to gradient index lenses. Only isotropic media are considered since they are the ones for which the refractive index at each point is independent of direction. Comprised of 12 chapters, this book begins with a historical background on the use of gradients in astronomy and developments in gradient index lenses, along with the underlying basic theory. The discussion then turns to spherical gradients, paying particular attention to rays, Maxwell's fisheye lens, the Luneburg lens, and astronomical refraction. Subsequent chapters focus on the ray trace in a spherical gradient; axial gradients and their use as an anti-reflection coating; radial gradients and ray tracing in a radial gradient; and fundamentals of aberration theory. The wood lens and ray trace in a general medium are also considered, together with methods for fabrication of gradient elements and measurement of index gradients using an approximate method and interferometric methods. This monograph will be of interest to physicists.
