New phase diagram of oxygen at high pressures and temperatures.
In situ high P-T Raman measurements and optical observations of solid and fluid oxygen up to 1250 K between 8 and 25 GPa reveal the existence of a new molecular phase eta and strikingly unusual behavior of the melting curve. Three triple points were also identified in the P-T domain of the new phase. The data give a direct measure of the melting curve that greatly extends previous optical inves...
متن کاملOxygen modulates growth of human cells at physiologic partial pressures
We have examined the growth of human diploid fibroblasts (WI-38 and IMR90) as a function of initial seeding density and oxygen tension. Cells at young and mid-passage levels were subcultivated in Dulbecco's modified Eagle's medium with 10% fetal bovine serum at 0.005, 0.01, 0.03, 0.1, 0.3, 1, and 2 X 10(4) cells/cm2. Flasks were equilibrated before and after seeding with 1 of 10 gas mixtures co...
متن کاملOXIDATION OF C/SiC COMPOSITES AT REDUCED OXYGEN PARTIAL PRESSURES
T-300 carbon fibers and T-300 carbon fiber reinforced silicon carbide composites (C/SiC) were oxidized in flowing reduced oxygen partial pressure environments at a total pressure of one atmosphere (0.5 atm O2, 0.05 atm O2 and 0.005 atm O2, balance argon). Experiments were conducted at four temperatures (816°, 1149°, 1343°, and 1538°C). The oxidation kinetics were monitored using thermogravimetr...
متن کاملCorneal swelling at low atmospheric oxygen pressures.
Corneas of 28 human subjects were exposed to oxygen partial pressures, in a gas goggle, of either 6.9, 17.1, or 22.2 mm Hg, and the corneal swelling was measured by pachometry for 4 hr. Following an initial rise, the swelling stabilized after about 3 hr; in many subjects it was reversed, indicating an adaptation process. The average corneal swelling after 4 hr for the three oxygen partial press...
متن کاملCorneal swelling at low atmospheric oxygen pressures
both cornea and conjunctiva occurred as early as 15 min after bacterial inoculation. By 1 to 3 hr after bacterial inoculation, shrinkage of corneal epithelial cells was pronounced (Fig. 5, a and b). Fewer microvilli were seen on the shrunken regions of these affected cells, and the cell surfaces appeared roughened and irregular. Additionally, intercellular junctions were dilated to 1.0 fim in d...
