Due to its better biodegradability, COD removal rate in anaerobic process can reach 62.1% under HRT of 24 h, and influent COD of 8 658.7-9 650.3 mg/L. The anaerobic effluent is treated by alternate anaerobic/aerobic SBR process, and the removal rate of COD and ammonia nitrogen comes up to 92.1% and (88.4)% respectively.
Density functional theory was employed to investigate atomic layer deposition(ALD)mecha-nism of zirconia on Si(100)-2×1 surface with single and double hydroxyl groups. The ZrO2 ALD process using ZrCl4 and H2O as precursors involves two alternate deposition half-reactions:ZrCl4 and H2O half-reactions.
Based on the moving mean slope(MMS) model developed by Moldrup for simulating water movement in unsaturated soils,the soil moisture variation with the root uptake term under the alternate infiltration and evaporation condition in agroforestry was computed.
Methods: The experimental animals were whole bodily exposed to 25-100mT alternate or constant magnetic field intermittently for 7 or 14 days, or to 3mT alternate magnetic field continuously for 5 or 10 days.
The contents of arginine vasopressin(APV) and β-endorphin(β-Ep) in hypothalamus、hypophysis and blood plasma were increased obviously in 75 and 100mT exposure groups, changed insignificantly in 25 and 50mT groups, and decreased in alternate 3mT exposure group.
Problems are considered of the asymptotic stability of the equilibrium of singular mechanical systems subjected to potential and dissipative forces under conditions of conventional control and alternate control.
Robust control algorithms are proposed, in which use is made of alternate paths with an arbitrary number of links.
We studied temperature dependence of phosphodiesterase activity in vernalized and unvernalized winter wheat on the one hand and in etiolated and red light illuminated seedlings of alternate wheat on the other hand.
However, fragmentation and fusion of mitochondria regularly alternate in the cell cycle of some unicellular and multicellular organisms.
