The pusherchain transmission is the core of shearing device, which occurred to the failure of getting stuck resulted in the chain-axis deformation. First, the paper presents the analysis of FMEA, FTA for deformation failure, and carries out the simulation research for failure analysis on wear-failure for chain plate. Then, based on the random effects of significant geometry, material properties, transmission...
The effect of culture conditions on the cis-epoxysuccinate hydrolase (CESH) production in recombinant Escherichia coli BL21 was investigated using response surface methodology (RSM), which was based on rotatable central composite design. The optimization of seed conditions consisted of a total of 13 experiments involving 4 star points and 5 replicates at the central points, while the optimization...
