Evaluating Aeration Criteria by Simultaneous Measurement of Oxygen Diffusion Rate and Soil-water Regime
SOIL physical properties are important for plant growth, but it is necessary to separate factors that affect plant growth directly from those that affect it indirectly.Water, oxygen, temperature, and mechanical resistance are interrelated factors that affect plant growth directly. An appropriate soil-water-air environment is essential for healthy plant growth. Letey (1985) introduced a nonlimit...
متن کاملHigh-temperature Operation of Oxygen Electrode Giving Fast Response for Respiratory Gas Sampling.
The 98% response time of the membrane-covered Clark-type polarographic oxygen electrode may be reduced to 0.4 sec. by heating the electrode and the gas sample flowing past it to 80#{176} when the electrode is covered with 0.25-mu (6 ,) Teflon membrane. The design of the microcathode electrode has been modified slightly to prevent drying out of the electrolyte and pressure changes within the ele...
متن کاملMeasurement of serum lipase activity with the oxygen electrode.
We describe the measurement of lipase (triacylglycerol lipase; EC 3.1.1.3) in serum by continuous monitoring of relative rates of oxygen consumption with a polarographic oxygen electrode. The reactions described by Proelss and Wright (Clin. Chem. 23: 522-531, 1977) are used: trilinolein, with lipase catalysis, yields linoleic acid, which reacts with oxygen in the presence of lipoxygenase. Lipas...
متن کاملEffects of pH and aeration on gamma-poly(glutamic acid) formation by Bacillus licheniformis in controlled batch fermentor cultures.
Bacillus licheniformis ATCC 9945A was grown on Medium E in batch fermentations in which the pH was maintained at 5.5., 6.5, 7.4, and 8.25. The effects of pH on cell growth, carbon source utilization, and gamma-polyglutamic acid (gamma-PGA) production, molecular weight, and polymer stereochemistry were determined. The gamma-PGA yield was highest (15 g/L, 96 h growth time) at pH 6.5. The increase...
متن کاملEffective enhancement of electrochemical properties of LSM oxygen electrode in SOCs by LNO nano-catalyst infiltration
In this paper, the effects of infiltration of La2NiO4 (LNO) as a mixed ionic and electronic conductor (MIEC) on the electrochemical performance of porous strontium doped lanthanum manganite (LSM) oxygen electrode of solid oxide cells, in the temperature ranges of 650-850 °C, is reported. XRD and FE-SEM results of the LNO sample calcined at 900 °C confirmed the formation of single phase LNO nano...
