  • Recombinant DNA

    Science, Ethics and Politics
    • 1st Edition
    • John Richards
    • English
    Recombinant DNA: Science, Ethics, and Politics emerged from papers presented at a conference, Ethical and Methodological Dimensions of Scientific Research: Recombinant DNA, A Case Study, held at the University of Georgia, April 15-16, 1977. Starting with an introduction to the methods and uses of recombinant DNA technology, the remaining contributions made by researchers at the symposium are organized into four parts. The first part contains papers on the development and utilization of recombinant DNA technology; genetic engineering in agriculture; and the dangers of unrestricted research. The second part focuses on the ethical aspects of recombinant DNA research. It includes studies such as ethical prerequisites for examining biological research; the limitations of broad moral policies; and ethical theories underlying the recombinant DNA controversy. The third part examines the legal aspects of recombinant DNA research and examines the issue of whether such research should be regulated. The papers in the fourth part consider directors for future research.

  • Physical surfaces

    • 1st Edition
    • J.J. Bikerman
    • English
    Physical Surfaces deals with the basic concepts of the physics of surfaces, including the nature of the surface pressure of unimolecular films and the equilibrium pressure of these films. The effect of particle size on capillary pressure, the surface energy and the cuticular energy of solids, and the fundamentals of wetting are also examined. This book is comprised of nine chapters and begins with a discussion on the mechanics and physical chemistry of liquid surfaces, with emphasis on capillarity and surface tension. The following chapters focus on liquid-liquid interfaces, foams and emulsions, and solid surfaces. Interfacial tension is analyzed in relation to miscibility and surface tension, along with contact angles in gas-liquid-liquid systems. The chapter on wetting looks at theories of contact angle, its measurement, and hysteresis. Adsorption and electric surface phenomena are also explored, together with adhesion and friction. This monograph will be a valuable resource for physical chemists and physicists.

  • Microprobe Analysis of Biological Systems

    • 1st Edition
    • Thomas Hutchinson
    • English
    Microprobe Analysis of Biological Systems covers the proceedings of the 1980 Microprobe Analysis of Biological Systems conference held at Battelle Conference Center in Seattle, Washington. Most of the major laboratories in the field of biological microanalysis in the United States, England, Scotland, France, and Germany are represented. The conference presents the findings, theories, techniques, and procedures of the laboratory represented, no matter how tentative and exploratory. This book is divided into four parts encompassing 22 chapters that focus on biological applications of microprobe analysis. The introductory part describes the application of electron microprobe and X-ray microanalyses in studies of epithelial transport, avian salt gland, electrolyte transport, and acrosome reaction. The subsequent part covers the application of microprobe techniques in the analysis of cardiac, skeletal, vascular smooth, and freeze-dried muscles. It also describes a method for obtaining erythrocyte preparations for validating biological microprobe methods and the continuum-fluorescen... effect on thick biological tissue. The method using freeze-substitution to localize calcium in quick-frozen tissue for X-ray microanalysis is also explained. The third part of the book tackles the principles, basic features, and applications of electron energy-loss spectroscopy. Discussions on the use of inner-shell signals for a quantitative local microanalysis technique; theoretical study of the energy resolution; and collection efficiency of a magnetic spectrometer are also included. The final part covers the elemental distribution in single erythrocytes using X-ray microanalysis. It also discusses the fundamentals of cryosectioning process for X-ray microanalysis of diffusible elements and the freezing behavior of a number of chemically different gels chosen for their partial resemblance to biological structures. Considerable chapters contain materials and methods, results, discussions, conclusions, and references. This book will be of value to scientists interested in elemental and ion transport within cells and between cells and extracellular compartments.
