Autor: E. N. Zinchenko, S. N. Roshchupkin, L. Ya. Arifov, Aleksander Petrovitch Lelyakov
Publikováno v: Theoretical and Mathematical Physics. 141:1593-1607
We find a new solution describing a homogeneous stationary axially symmetric model, which, in contrast to the Godel model, does not contain closed timelike lines. We find exact solutions corresponding to the motion of a null string in the rotating Un

On an approximate description of string andp-brane dynamics in curved space-time
Autor: S. N. Roshchupkin, A. A. Zheltukhin
Publikováno v: Theoretical and Mathematical Physics. 111:714-722
A new formulation for the action of the Nambu-Goto string moving in curved space-time is studied. The action contains a two-dimensional “cosmological” world-sheet term multiplied by a tension parameter. It is shown that when treating this cosmolo

Publikováno v: Gigiena i sanitariia. (3)
Sonographic parameters of spleen in children living in the Orenburg region taking into account the level and character of anthropogenous pollution of territory of residing are studied. The analysis of indicators of pollution of factors of inhabitancy

[Children's health status in relation to the level and nature of anthropogenic pollution]
Autor: V V, Sumenko, V M, Boev, S E, Lebed'kova, A N, Roshchupkin
Publikováno v: Gigiena i sanitariia. (1)
The frequency of health groups 1 and 2 was studied in children living in the areas of the Orenburg Region, by taking into account the level and nature of their anthropogenic pollution. The pollution indicators of environmental objects (ambient air, d
