Download or read book Measurements of the Dissociation Rate of Molecular Oxygen written by Charles J. Schexnayder and published by . This book was released on 1961 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ability of molecular oxygen to absorb light in the Schumann-Runge ultraviolet region of the spectrum has been used to follow the change in concentration of molecular oxygen as a function of time behind shock waves in oxygen and in a mixture of 10-percent oxygen in argon. Analysis of the records obtained yielded values for the dissociation rate of oxygen as a function of temperature over the range 4,000° to 10,000°K. The highest previously reported experimental results in the literature were at 7,500°K.

Available in PDF, EPUB and Kindle. Book excerpt: This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.

Available in PDF, EPUB and Kindle. Book excerpt: The High Temperature Aspects of Hypersonic Flow is a record of the proceedings of the AGARD-NATO Specialists' Meeting, held at the Technical Centre for Experimental Aerodynamics, Rhode-Saint-Genese, Belgium in April 1962. The book contains the papers presented during the meeting that tackled a broad range of topics in the aspects of hypersonic flow. The subjects covered during the meeting include pressure measurements, interference effects, the use of wind tunnels in aircraft development testing, high temperature gas characteristics, boundary layer research, stability and control and the use of rocket vehicles in flight research. Aerospace engineers and aeronautical engineers will find the book invaluable.

Available in PDF, EPUB and Kindle. Book excerpt: "On the basis of the atmospheric composition given by F.S. Johnson in 1960, the contribution of auroral particles to the dissociation of oxygen molecules in the polar upper atmosphere is investigated. The maximum rate coefficients are 4 x 10−8 (cm3 sec)−1 and 2 x 10−8 (cm3 sec)−1 for protons of energy spectrum E−2.8 dE and for electrons of energy spectrum E−4 dE, respectively. The height of maximum dissociation is around 90 km both for protons and electrons. The heating of the polar mesosphere by exothermic association of the oxygen atoms, intensified by the subsidence of the upper polar atmosphere during the polar night, is calculated and found to be close to the estimate given by W.W. Kellogg in 1961. The investigation indicates, however, that Kellogg's estimate should be reduced slightly to allow for the cooling effect produced by far infrared emission from atomic oxygen in the upper atmosphere."--Page i.

Book excerpt: The University of Manchester hosted the 28th International Symposium on Shock Waves between 17 and 22 July 2011. The International Symposium on Shock Waves first took place in 1957 in Boston and has since become an internationally acclaimed series of meetings for the wider Shock Wave Community. The ISSW28 focused on the following areas: Blast Waves, Chemically Reacting Flows, Dense Gases and Rarefied Flows, Detonation and Combustion, Diagnostics, Facilities, Flow Visualisation, Hypersonic Flow, Ignition, Impact and Compaction, Multiphase Flow, Nozzle Flow, Numerical Methods, Propulsion, Richtmyer-Meshkov, Shockwave Boundary Layer Interaction, Shock Propagation and Reflection, Shock Vortex Interaction, Shockwave Phenomena and Applications, as well as Medical and Biological Applications. The two Volumes contain the papers presented at the symposium and serve as a reference for the participants of the ISSW 28 and individuals interested in these fields.

Download or read book Photochemical Models of Stratospheric Ozone a Review written by Samuel Y. K. Yee and published by . This book was released on 1974 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Existing photochemical theories of stratospheric ozone are surveyed. Recent modifications to Chapman's 1930 classical model have been focused on the search for additional sinks for stratospheric ozone, while relatively little attention has been given to the uncertainties in its production rate. A critical discussion is presented on the uncertainties involved in the photo-dissociation rate of molecular oxygen which is the determining factor in the ozone production rate. (Author).
