Polarization for Au/Pb(Zr Ti )O /YBa Cu O ferroelectric capacitor has been studied and measured by pulse method. A sequence of pulses with amplitudes varying from 0 to 10 volts in 2 volt steps is applied and a conventional ...

In this paper we describe how the degrees of the irreducible characters of the affine subgroups of the classical groups under consideration can be found inductively. In [4] Gow obtained certain character degrees for all ...

An analysis of selected fission fragment angular distributions from helium-ion induced fission is made using an exact theoretical expression. Theoretical anisotropies obtained with the transition state model are compared ...

We have studied the phase transitions in atomic clusters by molecular dynamics simulation, assuming Lennard-Jones interatomic pair potential. Calculations are performed by DAP parallel computer. The results are analyzed ...

Two types of hydride electxodes are potential candidates to replace the Cd elecsode in NilCd batteries, One is of the A type where A is a rare earth metal or mixture thereof, and B is the transition metal. The other is ...

Molecular modeling analysis of charge density and heat of fornation by PM3 method as well as C, H NMR and 2D-NMR measurements of histidine (substrate) and some of its derivatives as histidine decarboxylase inhibitors ...

The reaction of PbCI, with 1,4,10,13-tetra-oxa-7, 16-diaza-cyclooctadecane (L= C H N O ) yielded colourless crystals of LPbCI . The complex crystallizes in monoclinic space group, C2/c, a = 7.90(2), b = 14.75(3) and C ...

Diazotization of 3-amino-2-cMoro pyridine (3) in the presence of dithizone (5) gave dphenyl-2-phenylazo-4H-pyrid[o3 ,2-e] [1,3,4] thiadiazine (6). Reaction of 2- chloro-3-nitropyridine (2, G=H) with (5) dfordd 4-phenyl ...

Three high-silica mordenite zeolites differing in SiO440, ratio were prepared by direct synthesis without using any template. The products Si02/A120, ratio is influenced by the starting gel composition. This ratio is ...

A number of complexes in the series (Cu LL'),, where L = [(CH,),C-CO-CH-COC( CH,),]-I and L'= 3-(Me) C6H,0-, 2,6-(Di-Me)C6H30-, 4-(OH)C6H?O-, 3- (F) C6H,0-, 4-(Br)C6H40-a, nd 3,s-(Dl-Me)C6H30h- ave been prepared and theu ...
