  • A demi-closed theorem and some new weak convergence theorems of iterative sequences for asymptotically nonexpansive and nonexpansive mappings in Banach spaces are obtained. The results presented in this paper improve and extend the corresponding results of [1],[8]-[10],[12],[13],[15],[16], and [18].

  • Kinetic resolution of various racemic aromatic epoxides by newly isolated Aspergillus niger LK has been investigated, and enantioselectivity of whole-cell biocatalyst was analyzed. The epoxide hydrolase (EHase) of A. niger LK was cloned using RT-PCR. The sequence homology was compared with that of other microbial EHase and the gene for EHase was characterized at molecular level.

  • We investigate a procedure which detects the parameter change point in AR(1) by Bayesian Approach using Jeffrey prior, for example, coefficient change point, variance change point, coefficient and variance change point, etc. And we apply our procedure to the simulated data.

  • The blowdown transient pipe flows resulting from the actuation of the safety/relief valve (SRV) under valve opening conditions have been analyzed. The analytical model has been developed for a uniform pipe with friction through which the flow is discharged into a suppression pool in case of a sudden opening of the SRV The piping flow characteristics and dynamic loads are calculated. Effects of system pressure, pipe length and submergence depth are included.
