Numerical simulations are conducted to calculate velocity fluctuations in a simple two-dimensional model of foam under steady shear. The width of the velocity distribution increases sublinearly with the shear rate, indicating that velocity fluctuations are large compared to the average flow at low shear rates (stick-slip flow) and small compared to the average flow at large shear rates. Several...
Recombinant Escherichia coli systems expressing organophosphorous hydrolase (OPH) have been proposed for biotransformation of toxic organophosphate compounds. However, whole cell biocatalyst systems are critically disadvantaged due to substrate diffusion limitations. To enhance whole cell biocatalytic efficiency, we engineered E. coli, for the first time, to secrete metal ion cofactor-requiring...
To reduce storage space and transportation cost for alfalfa and straw bales, recompressing of the bales is recommended. In order to design different units and elements of double compressing device, some physical and rheological properties of desired products were determined. A factorial experiment with a randomized complete block design with three replications was used during the tests. Confine...
In order to explore the effect of space environments on Bacillus cereus, we determined the draft genome sequence of a B. cereus strain, LCT-BC235, which was isolated after space flight.
A central feature in the Hilbert space formulation of classical mechanics is the quantisation of classical Liouville densities, leading to what may be termed term Groenewold operators. We investigate the spectra of the Groenewold operators that correspond to Gaussian and to certain uniform Liouville densities. We show that when the classical coordinatemomentum uncertainty product falls below He...
