We used phosphorus-31 nuclear magnetic resonance to test the ability of a perfluorocarbon blood substitute that has been shown in previous studies to improve oxygen delivery to hypothermic myocardium to maintain aerobic high-energy phosphate metabolism during total global ischemia. Twenty-three isolated perfused rabbit hearts were subjected to 180 min of hypothermic (23 degrees C) global ischem...

Emission spectra of the microplasma discharge in N2, NO and O2 gas mixture was analyzed. The diagnosis of microplasma discharge was performed in order to understand the processes of NOx removal. An experimental Marx Generator was used as a pulsed power supply. Emission spectra for N2 gas show N2 second positive band system (N2 SPS) and N2 first negative band system (N2 FNS). 1000 ppm NO in N2 e...

Production of active species is studied in N2 and in N2-O2 afterglows of electrical discharges at low and atmospheric gas pressures. They are produced in microwave discharges in a large range of gas pressures from a few Torr to 100 Torr and in corona discharges at atmospheric gas pressure. The active species in N2 afterglows are the N-atoms which are in the range of a few percents in the afterg...

[1] Motivated by the use of atmospheric O2/N2 to determine CO2 sinks under the assumption of negligible interannual variability in air-sea O2 fluxes, we examine interannual fluctuations of the global air-sea flux of O2 during the period 1980 – 1998 using a global ocean circulation and biogeochemistry model along with an atmospheric transport model. It is found that both the El Niño/Southern Osc...

Recent experimental and theoretical results show that the collision pairs, O2⋅O2 and O2⋅N2, absorb a small but significant fraction of the globally incident, solar radiation (Pfeilsticker et al. 1997, Solomon et al. 1998, Mlawer et al. 1998). The contribution of the water vapor dimer to shortwave (SW) absorption, however, remains speculative due to uncertainties in both its abundance and its ab...

Silicon nitride (Si3N4) etching using CF4/O2 mixed with N2 has become very popular in 3D NAND flash structures. However, studies on Si3N4 dry based optical emission spectroscopy (OES) are lacking; particular, no study reported the use of OES for analyzing N2-mixed plasma. Thus, this demonstrates an OES-based approach a mixed-gas plasma thin films. The state each single gas CF4, O2, and as well ...

Freshly harvested high-moisture corn with 29.4% moisture and corn remoistened to 19.6% moisture were inoculated with Aspergillus flavus Link ex Fr. and stored for 4 weeks at about 27 C in air (0.03% CO2, 21% O2, and 78% N2) and three modified atmospheres: (i) 99.7% N2 and 0.3% O2; (ii) 61.7% CO2, 8.7% O2, and 29.6% N2; and (iii) 13.5% CO2, 0.5% O2, and 84.8% N2. Kernel infections by A. flavus, ...

We report the electrical responses of thin and thick single-walled carbon nanotube (SWNT) networks to N2 and O2 adsorption. In the surface desorbed state exposure to N2 and O2 provide an increase in conductance of thin and thick SWNT networks. The increase in conductance of both thin and thick networks is of a greater magnitude during O2 exposure rather than N2 exposure. Thin networks exhibit a...

abstract sour cherry (prunus cerasus l.) is an important iranian-native fruit, considered highly perishable commodity which cannot be stored for any length of time. on this study, effect of three gas compositions (ambient, 5% o2+5% co2+90% n2 and 10% o2+15% co2+75% n2) and two storage temperatures (0 and 5 °c) on two sour cherry cultivars namely erdy jubileum and erdy botermo was studied in a c...
