Bacterial strains D11, E1 and E2 isolated from petroleum-contaminated soils were found to be members of Acinetobacter genus revealed by 16S rRNA gene sequence analysis phenotypic characteristics. After incubation for 5 days, about 43%, 9% 12% total petroleum hydrocarbons crude oil degraded E2, respectively, determined GC-MS analysis. Moreover, 70% 76% single hydrocarbon hexadecane was the D11 a...

Graphite-like carbon nitride (g-C3N4) is considered as a promising candidate for energy materials. In this work, the biaxial strain (?4%–4%) effects on piezoelectric properties of g-C3N4 monolayer are studied by density functional theory (DFT). It found that increasing can reduce elastic coefficient C11-C12, and increases stress e11, which lead to enhanced d11. Compared unstrained one, 4% raise...

In repeated games with di®erential information on one side, the labelling \general case" refers to games in which the action of the informed player is not known to the uninformed, who can only observe a signal which is the random outcome of his and his opponent's action. Here we consider the problem of minimizing regret (in the sense ̄rst formulated by Hannan [8]) when the information available...

for better understanding of conformational stability of the dipeptide model hco—gly—l—leu—nh2,ab initio and dft computations at hf/6-31g(4 6-311++g(d,p) and b3lyp/6-31g(d) levels oftheory were carried out. geometry optimization of the dipeptide within the leucine (leu) side chainangles (x2 ,x2) resulted in three stable conformations as followings: anti-anti, the most stable one,(xi = 180°, x2 =...
