The difference of τB and τ∧b indicates the role of the light flavors. We calculate the lifetimes ofB-meson and ∧b based on the weak effective Hamiltonian wh
By using the logarithmic strain, the finite deformation plastic theory, corresponding to the infinitesimal plastic theory, is established successively. The plas

Ultra high molar mass polyethylene (UITPE) powder as polymerized in a slurry process has been studied, in its nascent state, after recrystallization on rapid co
The boundary integral equation (BIE) of displacement derivatives is put at a disadvantage for the difficulty involved in the evaluation of the hypersingular int
At room temperature,the reaction of dibenzoyl peroxide with metallic copper powder in the presence of pyridine affords the copper(Ⅱ)complex [Cu(C5H5N)2(H2O)-(C
