In the present study, a defined consortium of Pseudomonas sp. MO2A and Debaryomyces maramus CW36 was studied to assess their potential for enhancing degradation and detoxification of polychlorinated biphenyls (PCBs) in liquid medium. The optimum pH of the medium was 6.0 for PCB degradation by the consortium. At this pH, the coculture of the bacterium and the yeast showed promoted PCB degradation (69...
Human APOBEC3G (hA3G), a cytidine deaminase with two cytidine deaminase domains (CDs), has been identified as an anti-HIV-1 host factor. Although the two CDs of hA3G have been extensively characterized, there is still debate on the role of the CDs in the biological function of hA3G. In this work, we constructed three hA3G mutants CD1-1, CD2-2 and CD2-1, which contain duplicate CD1 domain, duplicate...
The continuous-state fault tree (CSFT) is used for reliability analysis for the degradation performance of SLD. Firstly, the degradation performance of SLD is analyzed and the methods of building CSFT are proposed. Based on CSFT, the formula for reliability is deduced. Secondly, the reliability quantitative analysis of SLD is introduced based on the building CSFT of SLD. Thirdly, the reliability curve...
The ozonation of three organ phosphorus pesticides, malathion, diazinon and dimethoate, was conducted in water. The influence of the concentration of ozonated water, ozone action mode, degradation time and ion scavenger was discussed. The three organ phosphorus pesticides could bed gradated completely in 15min by bubbling ozone in water. And additional ion scavengers could increase the degradation...
As a new type of rotation sensor, the Fiber Optic Gyro (FOG) is rapidly developed. The storage life of FOG is an important part of the life of FOG. On the analysis of theory of FOG and the theory of the reliability theory, this paper has a discussion on how to manage the storage life of the FOG. It brings out a way to evaluate the storage life of the FOG, and validates its feasibility through the...
The binary state is the fundamental assumption to the traditional FTA. Hence, the traditional FTA gives only the binary logical analysis of product catastrophic failures. However, performance of Fiber Optical Gyroscope (FOG) will degrade with the time and it is able to perform its task with partial performance. To overcome this problem, multistate reliability analysis is presented. However, multistate...
