In application to the Crimean regional centre for satellite data reception, treatment, and dissemination, we have identified
the earth’s satellite-surveyed areas, with orbital heights (H) ranging from 650 to 750 km. This paper shows that for the Ukrainian territory and the Sea of Azov-Black Sea environment
to be monitored, the regional centre’s receiving station must be capable of receiving radar signals from a range of about
1500 km. For typical high-speed radio lines, this may be achieved through the use of a satellite data-receiving station, with
the antenna’s diameter being about 3 m.

cDNA's coding for cytochrome P4501A1 (CYP1A1), phenol UDP-glucuronosyltransferase (UDPGT) and glutathione S-transferase (GST-A) were cloned and sequenced from an expression library prepared from the liver of a 3-methylcholanthrene (3-MC) induced plaice. Plaice CYP1A1 and Phenol UDPGT display a high degree of structural conservation with homologous mammalian isoforms and their mRNAs were shown to be highly induced in liver after 3-MC treatment of fish. Expression of plaice GST-A, which displays closer homology to GSTs from plants and invertebrates than those of mammals, is repressed after 3-MC treatment. 相似文献

The paper considers the application of self-organizing models, specifically, the method of grouped arguments consideration
(MGAC), to forecast short and non-stationary time series of observations in the ocean. A sequence of operations for the treatment
of observational series is suggested. To assess its efficiency, we have used mean monthly oxygen concentration data collected
in the surface and near-bottom layers of the Taganrog Bay. It is shown that the application of the MGAC model allows one to
reduce by two times the root-mean-square error of that of the series prediction by five points, in comparison with the Jenkins-Box
regressional model. It has been concluded that the predictors' non-linear functions may be effectively used in the treatment
of short samplings.

The currents and surface level oscillations in the Sea of Azov ensuing from contraction of the mouth of Taganrog Bay are computed using the grid technique on the basis of a numerical solution to the system of quasi-linear, degenerate, parabolic, partial derivative equations (shallow-water equations). It is demonstrated what changes are to be expected in the dynamics of the Sea of Azov should this project be realized. The computations were carried out for typical wind directions.Translated by Vladimir A. Puchkin. 相似文献
