Inverse problems for non-uniformly polarized piezoelectric rods

Autor: O. B. Dombrova, V.Ye. Zhirov, Alexander O. Vatulyan

Publikováno v: Journal of Applied Mathematics and Mechanics. 71:85-92

Formulations of inverse coefficient problems of electroelasticity for non-hyperbolic-type operators are presented and calculation schemes for determining the piezoelectric modulus as a function of the coordinates in the one-dimensional case are propo

Publikováno v: Russian Chemical Bulletin. 42:1717-1723

The formation of trichlorogermyl-substituted amides, lactams, and imides occurs when 2Et2O·HGeCl3 is condensed with compounds possessing the -NCH2Cl fragment and equally well when HGeCl3 interacts with compounds containing -NCH2OH and-NCH2OSiMe3 gro

Publikováno v: Theoretical and Experimental Chemistry. 25:355-358

35C1 NQR spectra of compounds containing the fragment C13Ge-C-N-C(O)X, which were acquired at 77 K, indicate that in most of the investigated compounds the germanium atom is pentacoordinated owing to the intramolecular interaction Ge ← 0. The35C1 N
