The goal of this research was to isolate and identify the thermostable alkaline protease producing bacteria among several native Iranian microorganisms. At the end of screening program, a Bacillus subtilis BP-36 strain producing thermophilic alkaline protease was isolated from a hot spring in Ardebil province. The target enzyme was purified using a one-step Aqueous two-phase systems (ATPS) prot...

1. Introduction. In 1947 Tadeusz Wa˙ zewski [35, 36] proved his famous Retract Theorem. Roughly speaking the theorem states that if the trajectories of a flow leave a closed set W through a subset W − of the boundary of W , do it " transversally " , and the set W − is not a deformation retract of W then there exists a trajectory of the flow entirely contained in W. (We put the word trans-versal...

The crystal structure of the title compound, (C(6)H(12)N(5)O)(4)[W(12)(SiO(4))O(36)]·6H(2)O, consists of an α-Keggin-type [W(12)(SiO(4))O(36)](4-) polyoxidoanion, four [(2H-tetra-zol-5-yl)meth-yl]morpholinium cations and six uncoordinated water mol-ecules. In the cations, the morpholine rings display chair conformations. Extensive N-H⋯O, N-H⋯N, O-H⋯O and O-H⋯N hydrogen bonds are present in the ...

The paper presents characteristics of a permanent magnet synchronous machine designed for micro-hybrid electric vehicle operation. Appropriate design of interior permanent magnet machine with 36 stator slots and 8 stator poles for operation in motor and generator operation mode was investigated. Finite element analysis is employed in order to determine the machine performance. Streszczenie. W a...
