of chalcopyrite with moderately thermophilic microorganisms rather than mesophiles, since moderately thermophilic microorganisms greatly improve the reaction kinetics and thus improve copper extraction during... 2.4.1. Free and attached cells were counted by using a blood cell counting chamber under an optical microscope (Olympus, Tokyo, Japan). 2.4 Community structure analysis 2.4.1 DNA extraction from free......
through the CM data without relying on any physical failure mechanism. And, some nice mathematical properties of stochastic models can be used to analyze the estimated RUL. Wiener degradation process......
of ultrasonics on upsetting of a model paste[J]. Ultrasonics, 2002, 40(1/8): 43-48. [4] ZHUANG Xin-cun, WANG Jia-peng, ZHENG Huan, ZHAO Zhen. Forming mechanism of ultrasonic vibration assisted compression[J......
to the substrate and adsorption on the MgAl2O4 substrate of Zn, Fe, Al and O-bearing ions; 2) the break-up of any complex ions that may be involved on the surface; 3) surface diffusion of adsorbed ions and 4... depletion in spinel forming elements. This formation of the interaction layer was combined with the dissolution and diffusion of MgO and Al2O3 in the slag phase. Fig. 13 Proposed mechanism for slag......
there and achieve the denitrification effect [35]. Mechanisms such as volatilization, ammonification, nitrification (or denitrification), plant uptake (C. alternifolius, P. crispus), matrix adsorption (zeolite.... anguillicaudatus and B. aeruginosa, which could prevent a further endogenous nitrogen from release. This synergy of biota interactions, adsorption of the matrix and microorganisms could enhance both the TP......
. On the basic of these studies, the characteristics and forming mechanism of warm hydro- mechanical deep drawing technology were also explored. However, the technology needs some additional equipments......
fixed on river bed. The transient shear stress on river bed was treated as a crucial hydrodynamic mechanism when handling sediment incipience and transport. Then, river-bed volumetric sediment..., and analyzed the processes of adsorption and desorption of pollutants on suspended sediment. Sharma et al [16] studied experimentally the flow past a spur dike on a rigid bed meandering channel......
