Cu-Mn mixed oxide catalysts have been prepared by citric acid complex method and evaluated in the catalytic combustion of methyl acetate. The catalysts are characterized by X-ray diffraction (XRD) and Temperature¨Cprogrammedreduction (TPR). Doping an appropriate amount of Cu inMn3O4 is favorable for the formation of a stable solid solution. Thus, the(More)
The electroweak corrections at the order of O(αewm 2 t(b)/m 2 W ) to the partial widths of the t̃2 → g̃ + t and g̃ → t̃1 + t̄ decays ( depending on the masses of the particles involved ) are investigated within the Supersymmetric Standard Model. The relative corrections can reach the value of 10% in some parameter space, which can be comparable with the(More)
Many nature reserves are established to protect the habitat needs of particular endangered species of interest but their effectiveness for protecting other species is questionable. In this study, this effectiveness was evaluated in a nature reserve network located in the Qinling Mountains, Shaanxi Province, China. The network of reserves was established(More)
We investigated the electroweak corrections from one-loop diagrams involving the third generation (s)quarks to the decay width of process χ̃+1 → W+χ̃01 in the framework of the Minimal Supersymmetric Standard Model. Our calculation shows that these corrections are not very sensitive to the mass of the lightest neutralino χ̃01 and the sbottom mixing angle θb,(More)
We study the properties and relations of fuzzy pseudo-filters of pseudo-BCK algebras. After we discuss the equivalent conditions of fuzzy normal pseudo-filter of pseudo-BCK algebra (pP), we propose fuzzy implicative pseudo-filter and its relation with fuzzy Boolean filter of (bounded) pseudo-BCK algebras (pP). Then two open problems: “In pseudo-BCK algebra(More)
