IntroductionRecently,organometallic-type ofreactions in aqueousmedia have attracted a considerableinterestin organic syntheses[1— 4] .The main advantage of mak
The optimal topology design of truss structures concerning stress and frictionless unilateral contact displacement constraints is investigated. The existence of
Mononuclear copper( Ⅰ ) complex [Cu(PPh3)2(NO3)] has been synthesized by ligand reduction of cupric nitrate with PPh3 in methanol and characterized by elementa
A vanishing theorem is proved for -adic cohomology with compact support on an affine (singular) complete intersection. As an application, it is shown that for a
In this paper, using an orthogonal curvilinear coordinate system and solving the complete N-S equations, we analyzed the flow in a helical elliptical duct by th
