Infalling thermally destroyed bodies as a possible explanation for the KIC 8462852 phenomenon

Autor: B. I. Demchenko, L. I. Shestakova, Aleksander V. Serebryanskiy

Publikováno v: Monthly Notices of the Royal Astronomical Society. 501:5468-5477

Using the analytical solution of the heat diffusion equation, we calculate the components of the thermal stress tensor and analyse the process of thermal destruction of bodies consisting of crystalline ice with radii ranging from 10 m to 10 km around

Results of observations of the dust distribution in the F-corona of the sun

Autor: B. I. Demchenko, L. I. Shestakova

Publikováno v: Solar System Research. 50:143-160

The results of modeling of the distribution of dust in the circumsolar zone are presented. The dust distribution was retrieved from observations of the line-of-sight velocities in the F-corona to the distances of 7–11 solar radii during the total e

Observations of the dust radial velocity field in the F-corona on March 29, 2006

Autor: F. K. Rspaev, A. Chalabaev, B. I. Demchenko, L. I. Shestakova

Publikováno v: Geomagnetism and Aeronomy. 51:1054-1057

The results of interferometer observations of the dust radial velocity field in the F-corona during the total solar eclipse of March 29, 2006, are presented. The observations were performed in the Mugalzhar settlement, Aqtobe region, Kazakhstan. The

Analysis of Terrestrial Radioactive Contamination

Autor: L. M. Karimova, Miroslav M. Novak, N.G. Makarenko, B. I. Demchenko

Publikováno v: Fractals. :359-369

The physics of terrestrial radioactive contamination is complex, primarily due to the mixtures of radionuclides, their migration, the effects of soil chemistry, and the prevalent climate. Consequently, application of classical techniques is inappropr

Esterification and acetalization of steroids in the presence of the heteropoly acid H3PW12O40

Autor: B. I. Demchenko, M. N. Timofeeva, I. V. Kozhevnikov, V. S. Grosheva

Publikováno v: Reaction Kinetics & Catalysis Letters. 45:215-219

H3PW12O40 and H3PW12O40/SiO2 are efficient catalysts for esterification and acetalization of steroids (testosterone, 17 α-hydroxyprogesterone, 11, 21-diacetoxy-16α-hydroxyprednisolone) at 40–82 °C.
