A pair of Z and E isomers of cyclization of γ-ketoacid 7,which was prepared in six steps from 2,5-dimethoxyphenyl acetic acid 1, gave a pair of Z(20%) and E (4
This paper considers a class of variational inequalities that model the buckling of a von Karman plate clamped on a part of its boundary and lying on a flat rig
Convenient, efficient one-pot synthesis of ferrocenylcyanide, which is a very important intermediate in synthesis of chiral ferrocenyl ligands in asymmetric cat
The interaction between multiple curved rigid line and circular inclusion in antiplane loading condition is considered in this paper. By utilizing the point for
The title complex was synthesized in an aqueous solution and its crystal structure was determined by X-ray diffraction. The crystal crystallizes in a triclinic
This note contains three main results.Firstly,a complete solution of the Linear Non-Homogeneous Matrix Differential Equations (LNHMDEs) is presented that takes
MCH 2(OH) and CH 3OM(M=-, Li, Na) were calculated by means of ab initio method at the MP2/631+G* level. The results show that the metals have the ability to l
In this paper the dual reciprocity boundary element method is employed to solve nonlinear differential equation 2 u + u + εu3 = b. Results obtained in an exa
