was studied by means of reverse transcription-polymerase chain reaction (RT-PCR). The result shows that high dose of Ce(NO3)3 (50 mg.kg-1) induces the increase of expression of calpain mRNA, but low dose of Ce......
100124, China) Abstract: The floc property and coagulation efficiency of conventional coagulation were compared with those of the grading coagulation. In addition, the parameters including grading dose interval and grading dose ratio were investigated. The results show that grading addition not only reduces the effluent turbidity, but also increases floc size and loosens floc structure. The turbidity......
Regression model for daily passenger volume of high-speed railway line under capacity constraintLUO Yong-ji(骆泳吉), LIU Jun(刘军), SUN Xun(孙迅), LAI Qing-ying(赖晴鹰) (State Key Laboratory of Rail Traffic Control and Safety (Beijing Jiaotong University), Beijing 100044, China)Abstract:A non-linear regression model is proposed to forecast the aggregated passenger volume of Beijing-Shanghai high-speed......
that both of uniformity coefficient and average particle size should be included in the uniformity analysis of the mineral particles. The results show that the effect of circulation fan impeller speed on particle uniformity is the most evident, HPGR working pressure and roll gap are second and HPGR roller speed is the last. Average particle size has a more obvious effect on the grade of flotation......
RELATIONSHIP BETWEEN J-INTEGRAL AND FRACTURE SURFACE AVERAGE PROFILE K.Tanaka1,S.F. Xue2,Y.G. Cao2 (1.Department of Mechanical Systems Engineering, Toyama Prefectural University, Toyama 939-0398.... The relationship between J-integral and fracture surface average profile for plain strain was deduced. It was also verified that the J-integral determined by the novel method and by the compliance method......
