Atmospheric Pressure Gas Lasers
1973Abstract : The work for this research contract on atmospheric-pressure gas lasers had as its main objectives the generation of short laser pulses through mode locking and cavity dumping, the study of the nonlinear amplification processes in a transversely excited atmospheric pressure laser, and development of computer programs to check the observed ...

Effect of Intraocular Gas on Intraocular Pressure
Archives of Ophthalmology, 1976The problems encountered in measuring intraocular pressure in eyes containing a compressible gas and the problem of determining the effect of changes in ambient atmospheric pressure on such eyes have been studied experimentally in enucleated human eyes and living rabbit eyes, and studied theoretically using the Friedenwald pressure-volume relationship,

High gas pressure effects on yeast
Biotechnology and Bioengineering, 2008AbstractDried microorganisms are particularly resistant to high hydrostatic pressure effects. However, exposure to high pressures of nitrogen proved to be effective in inactivating dried yeasts. In this study, we tried to elucidate this mechanism on Saccharomyces cerevisiae. High‐pressure treatments were performed using different inert gases at 150 MPa

Ga(U)Ge pressure and absolute pressure
Journal of Chemical Education, 1979Air is progressively removed from a test tube; the pressure inside is measured using a standard tire-pressure gauge that is found to read atmospheric pressure when the test tube is fully evacuated.

Gas‐gas equilibrium: High pressure limits
The Canadian Journal of Chemical Engineering, 1974AbstractRecent experimental studies of phase behavior in mixtures of light gases, at pressures up to ten thousand atmospheres, provide information about high pressure boundaries to regions of gas‐gas equilibrium. It is shown that these regions are generally bounded on the high pressure side by a three‐phase region of the type solid‐gas‐gas, which ...

In order to solve the evolution equations [Eqs. (4.36)–(4.38)] for the variables ρ, T, and X, we need to be able to express the auxiliary functions P, F, and q in terms of these variables. Additional physics must be included to accomplish this.

Having considered the average energy of an ideal gas, we now turn to the calculation of another simple mechanical property, namely the pressure P: the force per unit area that a gas exerts on the walls of its container. This Lecture presents three physically distinct calculations of P.The first calculation uses a direct approach based on Gibbs’s ...

Bursting Bacteria by Release of Gas Pressure
Nature, 1951MANY investigations of bacterial metabolism require that the contents of the cell be released. This apparently simple requirement has not yet been met in a completely satisfactory way. The present method differs in principle from previous techniques. It consists of sudden release of applied gas pressure and is very simple, rapid and inexpensive.

Wounding capacity of muzzle-gas pressure
International Journal of Legal Medicine, 2011Suicidal gunshot wounds that are caused by ammunition fired from a 9-mm Luger pistol, with direct contact between the gun muzzle and the victim's head, present a serious injury pattern even with full metal jacket bullets. Wound ballistic experiments were performed to clarify whether muzzle gases from the firearm have an additional wounding potential ...

Sonoluminescence and high-pressure gas scintillators
Physical Review E, 1996We point out striking similarities between the light emitted in single-bubble sonoluminescence and high-pressure gas scintillators. This observation can account for important and largely unexplained phenomena surrounding sonoluminescence. Especially, it explains the observed dramatic effects of the noble gas content on the spectral density of the light
