Download or read book Spectral Irradiance Enhancement from a Long Arc Xenon Lamp in the 460 495 Nm Bandwidth with Metal Additives written by R. G. Hughes and published by . This book was released on 1974 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: Long range, wide angle, deep ocean photographic systems require an intense, efficient, auxiliary lighting system due to the lack of sufficient natural illumination in the visible wavelength band and the magnitude of optical attenuation. A method of enhancing the spectral output from a pulsed long arc Xenon lamp in the 460-495 nm bandwidth, using metal additives was investigated. The light output from the lamp was generated by discharging a single mesh capacitor bank through the lamp. Initiation of the current pulse in the lamp was accomplished via an external trigger wire. Metal additives tested in the lamps included zinc, cadmium, and bismuth tri-iodide. Additive lamps with combinations of zinc and cadmium and bismuth tri-iodide; and cadmium and zinc were also fabricated.
Download or read book Long Term Durability of Structural Materials written by P.J.M. Monteiro and published by Elsevier. This book was released on 2001-08-29 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Long Term Durability of Structural Materials" features proceedings of the workshop held at Berkeley, CA in October, 2000. It brought together engineers and scientists, who have received grants from the initiative NSF 98-42, to share their results on the study of long-term durability of materials and structures. The major objective was to develop new methods for accelerated short-term laboratory or in-situ tests which allow accurate, reliable, predictions of the long-term performance of materials, machines and structures. To achieve this goal it was important to understand the fundamental nature of the deterioration and damage processes in materials and to develop innovative ways to model the behavior of these processes as they affect the life and long-term performance of components, machines and structures. The researchers discussed their approach to include size effects in scaling up from laboratory specimens to actual structures. Accelerated testing and durability modeling techniques developed were validated by comparing their results with performance under actual operating conditions. The main mechanism of the deterioration discussed included environmental effects and/or exposure to loads, speeds and other operating conditions that are not fully anticipated in the original design. A broad range of deterioration damage, such as fatigue, overload, ultraviolet damage, corrosion, and wear was presented. A broad range of materials of interest was also discussed, including the full spectrum of construction materials, metals, ceramics, polymers, composites, and coatings. Emphasis was placed on scale-dependence and history of fabrication on resulting mechanical behavior of materials.
Download or read book Spectroscopic Methods in Food Analysis written by Adriana S. Franca and published by CRC Press. This book was released on 2017-12-14 with total page 664 pages. Available in PDF, EPUB and Kindle. Book excerpt: Given the inherent complexity of food products, most instrumental techniques employed for quality and authenticity evaluation (e.g., chromatographic methods) are time demanding, expensive, and involve a considerable amount of manual labor. Therefore, there has been an increasing interest in simpler, faster, and reliable analytical methods for assessing food quality attributes. Spectroscopic Methods in Food Analysis presents the basic concepts of spectroscopic methods, together with a discussion on the most important applications in food analysis. The determination of product quality and authenticity and the detection of adulteration are major issues in the food industry, causing concern among consumers and special attention among food manufacturers. As such, this book explains why spectroscopic methods have been extensively employed to the analysis of food products as they often require minimal or no sample preparation, provide rapid and on-line analysis, and have the potential to run multiple tests on a single sample (i.e., non-destructive). This book consists of concepts related to food quality and authenticity, that are quite broad, given the different demands of the manufacturer, the consumer, the surveillance and the legislative bodies that ultimately provide healthy and safe products.

Houston, September 1973 B. JIRGENSONS Preface to the First Edition Great advances have been made in the application of physical methods in the study of the structure of proteins and other biological macromolecules. Optical rotatory dispersion has been successful in solving structural problems, and a vast amount of literature has accumulated on this subject. Several review articles appeared between 1961 and 1965, but significant progress has been made since 1965. Important new studies, especially on the Cotton effects in the far ultraviolet spectrum, have rendered many previous publications obsolete so that a concise monograph should be useful at this time.

With contributions from veterans in the field, as well as from up-and-coming researchers, the Handbook offers 30 substantial and well-referenced chapters. In addition to the introductory matter, forward-thinking descriptions are included in every chapter that make this a valuable reference for all those involved with optical metrology.
Download or read book Fluorinated Coatings and Finishes Handbook written by Laurence W. McKeen and published by William Andrew. This book was released on 2015-10-11 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluorinated Coatings and Finishes Handbook: The Definitive User's Guide, Second Edition, addresses important, frequently posed questions by end-user design engineers, coaters, and coatings suppliers on fluorinated coatings and finishes, thus enabling them to achieve superior product qualities and shorter product and process development times. The book provides broad coverage of these fluorinated polymer coatings, including the best known PTFE, polytetrafluoroethylene, first trademarked as Teflon® and ePTFE (GoreTex®). Their inherent qualities of low surface tension, non-stick, low friction, high melting point, and chemical inertness make fluoropolymer coatings widely desirable across thousands of industrial and consumer applications, but these properties also make it difficult to convert fluoropolymers to coatings that have sufficient adhesion to the substrate to be protected. In this book, readers learn how fluoropolymer coatings are used and made, about their pigments and fillers, binders, dispersion processes, additives, and solvents. The book includes substrate preparation, coating properties, baking and curing processes, performance tests, applications, and health and safety. Provides a practical handbook that covers the theory and practice of fluorinated coatings, including the structure and properties of binders and how to get a non-stick coating to stick to the substrate Covers liquid and power fluorocoatings, their applications methods, curing and baking processes, and their commercial end uses Presents detailed discussions of testing methods related to fluorocoatings, common coating defects, how they form, how to eliminate them, and the health and safety aspects of using and applying fluorocoatings Includes substrate preparation, coating properties, baking and curing processes, performance tests, applications, and health and safety
