Abstract -- Calculations are performed for the circular polarization of maser radiation from a turbulent, Keplerian disk that is intended to represent the sub-parsec disk at the nucleus of the galaxy NGC4258. ... This turbulence, along with the Keplerian velocity gradients and the blending of the three hyperfine components to form the 6 16 --5 32 masing transition of water, are key ingredients in determining the appearance of the polarized spectra that are calculated. ...

... Satellite data ] . SMIS ] . The program calculates the satellite orbit using ephemeris data in either predict-telegrams (APT predict, TBUS data) or 2-line NORAD format (TLE data). It determines the start and finish times of acquisition session and stores the data for antenna control during the receipt onto the hard disk. The program creates session schedules, supports selection of specific regions for observation and automatic filtration of satellite passes over the selected regions. ...

... During all period of our investigations Dr. N.Sumzina from the Institute of Applied Astronomy of RAS had prepared the Numbered Minor Planet positions from MPC Database for our processing with kind permission of the Director of Minor Planet Center Prof. Braian Marsden. ... Our extensive processing of the MPC data allows us to conclude that CCD observations of the Numbered and Unnumbered Minor Planets have the errors, sometimes very crude. ...

During 1665 - 1667 Newton made his three main discoveries: the method of fluxings and quadratures (differential and integral calculus, explanation of the light nature and the law of gravitation). ... In 1668 Newton built the first reflecting telescope. The big lens telescope gave indistinct image with painted edges. ... The scientist considered this problem indisolved and suggested a mean against chromatic aberration: a mirror must be used instead of objective lens. ...
