Application of the Program for Automatic Acquisition and Characterization of X-Ray Emission Spectra of Some Light Elements.
(Materials Science Monographs, 1982)
Investigation of the effect of the aminocarboxylato chelate conformation on the optical activity of the cis(NO2),trans(NH2) -bis(aminocarboxylato)dinitrocobalt/ate(III) isomers
In the cis(NO2),trans(NH2)-bis(aminocarboxylato) dinitrocobalt/ate(III) isomers, containing glycinato, S-alaninato, S-n-valinato, S-valinato, S-n-leucinato, S-leucinato, S-i-leucinato and S-arginine ligands, respectively, ...
Determination of Fluorine Ions Penetration Degree Into Enamel by Empa.
(Journal de Physique (Paris), Colloque, 1984)
Exogen of different preparations was applied to completely healthy teeth of children up to 11 years. A month after application of fluorine, teeth were extracted and prepared by standard methods for investigation by electron ...
Esca and Empa in the Analysis of Sulphides.
(Science of Sintering, 1985)
The purpose of the work was to determine the dependence of parameters describing XPS and XES spectra of sulfur on physico-chemical properties of some sulfides. The discussion considers chemical shifts of spectra correlated ...
Avarol-induced DNA strand breakage in vitro and in Friend erythroleukemia cells
(Cancer Research, 1987)
The hydroquinone-containing cytostatic compound avarol inhibits predominantly growth of those cell lines which have a low level of superoxide dismutase. The substrate of this enzyme, the superoxide anion, was found to be ...
Free radical annulation of cyclopentane ring
(Tetrahedron Letters, 1986)
Homoallyl radical, e.g. 2, reacts with an electron-deficient olefinic bond 1 with a new CC bond forming and arising of a 5-hexenyl radical 3 which further undergoes to 5-exo-trigonal cyclization with a cyclopentane ring ...
Suppression of the modulatory effects of the antileukemic and anti-human immunodeficiency virus compound avarol on gene expression by tryptophan
(Cancer Research, 1989)
The amino acid L-tryptophan is known to be a modulator of many processes of cell metabolism. In this contribution we show that L-tryptophan interferes with some biological effects of the antileukemic and anti-human ...
Free radical carbocyclic ring reconstruction
(Tetrahedron Letters, 1986)
Alkenyl radical generated by β-fragmentation of tertiary cyclohexyloxy radical with carbocyclic ring opening, possessing a suitably located olefinic double bond, undergoes to the intramolecular 5-exo-trigonal cyclization ...
Local electron density models for Tl to Pb conversion in lorandite
(Nuclear Instruments and Methods in Physics Research. Section A: Accelerators, Spectrometers, Detecto, 1988)
The nuclear conversion of 205Tl to 205Pb by neutrino capture, lorandite (TlAsS2) converts into Pb-bearing lorandite (Tl1-xPbxAsS2) where x is a very small number. Having used a highly simplified cluster model of lorandite, ...
Electrochemical reactivity of biologically active quinone/hydroquinone sesquiterpenoids on glassy carbon electrodes
(Bioelectrochemistry and Bioenergetics, 1987)
The redox reactivity of avarone and avarol, a quinone/hydroquinone couple isolated from the marine sponge Dysidea avara, was investigated by cyclic voltammetry, using a glassy carbon electrode. Both oxidation of avarol and ...
