The intensity of oxygen supply and steel output can be increased by 0. 5-1. 0 m3/t· min and 10 %-20 % respectively provided that the high-efficiency oxygen blowing technology is applied to the converter refining.
It estimates that a 6000m~3/h oxygen making machine supplying oxygen for 3×255m~3 blast furnaces can give a result of increasing FeMn productivity by 4l300t/y, coke-saving by 34300t and coke replacing with coal by 17500t.
Objective To study the relationships between supplied oxygen concentration (FsO_ 2 ), flow rate (flow) and inhaled oxygen concentration (FiO_ 2 ) in neonates when oxygen is given via oxygen hood; and to study what are the most effective ways of supplying oxygen in neonates.
The operation practice showed that 35% pig iron in charge for arc furnace,adding 3～10 mm carbon particle and strengthening supply oxygen to form 500～750 mm foaming slag were available to remove partial nitrogen in molten steel,as a consequence the average nitrogen in steel came to 45×10~(-6) at arc furnace tapping.
In this paper, on the basis of the characteristics of Qingzang Railway, with combination of the manufacture technique and manufacture cost of the cars, the way to supply oxygen for passenger cars on the Railway is discussed, and the oxygen supply scheme with the application of oxygen generator is suggested.
The catalytic wet oxidation of UDMH in wastewater was investigated in a trickly-bed reactor system with 30ml of catalyst, at temperature 200-250℃, pressure 50 kg/cm2 and LHSV 1.8-2.3. The ratio of the oxygen-supply to COD was 2 to 3 and the initial concentration of UDMH was 0.5 to 2,0 wt%.
It is likely that co-administration of angioblasts will also be needed to supply oxygen and nutrients to exogenously administered cardiomyocyte/mesenchymal stem cells in protocols to regenerate chronically damaged myocardium.
The enhancement of bioconversion was also observed when a gas-flow bioreactor was used to supply oxygen and to maintain the constant moisture of the reactor.
This was associated with an increase in both arterial hydrogen ion and lactate concentrations in 8 of the 11 patients studied, suggesting a deterioration in tissue oxygen supply/oxygen requirement.
The ability of alginate-entrapped microorganisms to supply oxygen was determined with regard to physiology and growth behavior of the cells.
Considering these results it is not possible to make a general statement on the ability of microorganisms in alginate to supply oxygen.
The relationship between oxygen-supply dependency and MOF and the practical implications of the relationship are reviewed.
Perilymph as a medium of oxygen-supply for the organ of corti
When rotifers were cultured with an oxygen-supply and pH was adjusted to 7, the maximum density of rotifer reached 33?500 ind.
However, after diltiazem, reduced exercise heart rates as well as reduced left ventricular end-diastolic pressure also contributed to the improvement in the oxygen-supply imbalance in the ischemic myocardium.
The smolder ing process is flexible enough to adapt to a wide range of oxygen-supply levels, including extraordinarily low levels.
