A soil bacterium capable of degrading chitin on chitin agar plates was isolated and identified as Bacillus pumilus isolate U5 on the basis of 16S rDNA sequence analysis. In order to optimize culture conditions for chitinase production by this bacterium, a two step approach was employed. First, the effects of several medium components were studied using the Plackett-Burman design. Among various ...

The frequency of linguistic phenomena is standardly measured relative to some structurally defined unit (e.g. per 1,000 words or per clause). Drawing on a case study on the acquisition of ergativity by children in Chintang, an endangered Tibeto-Burman language of Nepal, we propose that from a psycholinguistic point of view, it is sometimes necessary to measure frequencies relative to the length...

In order to obtain accurate discrete element simulation model (DEM) parameters of compound fertilizer and solve the problem challenging measurement contact particle, calibration test was carried out by using EDEM soft-ware. This study measured intrinsic particles through physical tests established a that corresponds with actual situation calibrate particles. By Blackett-Burman test, had signifi...

The production of extra cellular lipase in Solid State Fermentation (SSF) using Yarrowia lipolytica NCIM 3589 with Palm Kernal cake (Elaeis guineensis) has been studied. Different parameters such as incubation time, inoculum level, initial moisture content, carbon level and nitrogen level of the medium were optimized. Screening of various process variables has been accomplished with the help of...
