Download or read book Review of Progress Towards Developing a Sensor for the Measurement of CO2 in Hyperbaric Gaseous Environments written by Kevin G. Williams and published by . This book was released on 1975 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of a small, accurate and reliable alarm sensor to monitor the partial pressure of CO2 (pCO2) in the hyperbaric gaseous environment of the saturation diver is required to prevent his exposure to dangerous levels of CO2. Andros Incorporated has developed a novel, nondispersive infrared (NDIR) 'density modulation' technique meeting all the previously mentioned requirements. Using the technique, the number of CO2 molecules in the radiation path is varied periodically by subjecting a sample of the gas to a known density modulation and then measuring the fractional change in transmitted infrared radiation. Response and design are discussed.

Book Synopsis A Sensor for the Detection of CO2 in Hyperbaric Gaseous Environments by : Kevin G. Williams
Download or read book A Sensor for the Detection of CO2 in Hyperbaric Gaseous Environments written by Kevin G. Williams and published by . This book was released on 1977 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: The characteristics of the essential components of a Nondispersive Infrared (NDIR) gas sensor for measuring CO2 concentrations in hyperbaric gaseous environments have been studied. The technique used is to subject a known volume of sample gas to a periodic density modulation and to measure the amount of CO2 present by observing the fractional change in a beam of infrared radiation transmitted through that volume. A sensor that uses this technique has been built for use in habitats at pressures up to 600 psia. It measures 8 x 7 x 14 inches and operates directly from 28 volts DC. The sensor's response is not strongly pressure dependent (the maximum deviation from the response at 14.7 psia being only 18% of reading). Neither re-zeroing nor recalibration are necessary since the design inherently maintains both. 0 to 90% response is about 40 seconds for both increasing and decreasing pCO2. (Author).

Book Synopsis Development of a Carbon Dioxide Partial Pressure Sensor by : Gerald Jankowitz
Download or read book Development of a Carbon Dioxide Partial Pressure Sensor written by Gerald Jankowitz and published by . This book was released on 1964 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of the program was to design and develop a compact airborne CO2 sensor unit capable of sensing and measuring the CO2 content of manned, sealed environments. A prototype carbon dioxide sensor was designed, built, and calibrated. The sensor operates by alternately comparing the infrared absorption of the air sample at 4.26 microns, where CO2 exhibits strong absorption and at 3.90 microns where it has little absorption. A two color rotating filter provides sampling 200 times per second. The unit weighs 10 pounds and has a power consumption of 70 watts. The instrument is capable of detecting a concentration of at least 0.30% CO2 and has full scale capability to 5%. (Author).

Download or read book Handbook on Hyperbaric Medicine written by Giorgio Oriani and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 901 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hyperbaric oxygen application has now become a useful technique for both diagnostic and therapeutic purposes in CNS, cardiovascular and respiratory diseases, as well as in soft-tissue and orthopaedic pathologies and haematologic disorders. With a specific didactic approach, supported by numerous illustrations and tables, this volume aims to present all aspects of oxygen application under pressure not only to resolve some clinical problems, but also to improve recovery or to modify a negative illness evolution. Both scientists and practitioners will find this work a useful and updated reference book.

Book Synopsis Oxygen-Free Museum Cases by : Shin Maekawa
Download or read book Oxygen-Free Museum Cases written by Shin Maekawa and published by Getty Publications. This book was released on 1999-02-11 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the challenges in protecting and displaying environmentally sensitive objects is preventing deterioration caused by the presence of oxygen. This volume describes the design and construction of an oxygen-free, hermetically sealed, display and storage case developed by the Getty Conservation Institute for the long-term protection of such objects. The case was originally designed as a collaborative project between the Egyptian Antiquities Organization and the GCI to conserve the Royal Mummy Collection at the Egyptian Museum in Cairo. Seven chapters cover the protection of cultural objects from environmental deterioration by reducing exposure to oxygen and by using inert gases for biodeterioration control. Also included are details on how the design and construction of the oxygen-free case has been adapted for other applications, specifically for the original documents of the Constitution of India in New Dehli and for the mummy collections at the Egyptian Museum and at the Museu Victor Balaguer in Vilanova i la Geltru, Spain. The Research in Conservation reference series presents the findings of research conducted by the Getty Conservation Institute and its individual and institutional research partners, as well as state-of-the-art reviews of conservation literature. Each volume covers a topic of current interest to conservators and conservation scientists.

This new edition of the definitive text on capnography reviews every aspect of this valuable diagnostic technique. An introductory section summarises the basic physiology of carbon dioxide generation and transport in the body. A technical section describes how the instruments work, and a comprehensive clinical section reviews the use of capnography to diagnose a wide range of clinical disorders. Edited by the world experts in the technique, and with over 40 specialist contributors, Capnography, second edition, is the most comprehensive review available on the application of capnography in health care.
Book Synopsis Fruit and Vegetable Storage by : Anthony Keith Thompson
Download or read book Fruit and Vegetable Storage written by Anthony Keith Thompson and published by Springer. This book was released on 2015-09-21 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Brief reviews the effects of increasing and reducing atmospheric pressure on the postharvest life of fruit and vegetables. The text covers the common methods and technologies used and evaluates the history and benefits of hypobaric and hyperbaric storage. Both of these techniques have the potential to address quantitative and qualitative challenges in the postharvest sector of the fresh fruit and vegetables industry. Hypobaric and Hyperbaric Storage of Fruit and Vegetables reports on the effects of storage on over 45 types of fruit and vegetables, as well as on whole plants and cut flowers. As consumer demand for high quality product increases, proper postharvest storage will continue to gain in importance. The environmental conditions used in storage have a vital influence on the quality, safety and health benefits of fruit and vegetables.
