The conversion rule of the 3-ketosteroid-Delta1-dehydrogenation by Arthrobacter globiformis ATCC 31250 and the effect of the cell wall and cell membrane on biotransformation have been studied. Steroid compounds with different functional groups show a diversity of physicochemical properties at the macroscopic level. We measured the melting point, specific rotation and absorption coefficient of 3-ketosteroid...
In order to guarantee the safety of coal face production, it is necessary to monitor and surveillance face Shearer, scraper transport planes, hydraulic support, transport machines, broken machines etc . At present, it is difficult for the cable transmission mode to adapt to changes in the work site of the coal face. Transmission lines are often damaged and snapped for various factors, we use wireless...
This paper puts forward a comprehensive method for the evaluation of a logistic service provider using ANP. The proposed method consists of two parts: preliminary screening of the available providers, and an analytic network process-based final evaluation. The criteria, which are relevant in the evaluation of a provider, have been identified and used to construct an ANP model. Thereafter, the application...
A hybrid fuzzy LMS neural network model, with fuzzy numbers as inputs, is set up to determine the weights of each criterion of alternatives. The model can determine the weights of each criterion automatically, according to the time-series data of market, so that they are more objectively and accurately distributed. The model also has a strong self-learning ability so that calculations are greatly...
