N.N. Kolesnikov, M.P. Kulakov and Yu.N.Ivanov. Some properties of melts of A 2 B 6 compounds. Abstract: . Devices for experimental determination of surface tension and viscosity of A 2 B 6 compound melts have been developed. Surface tension, viscosity and volume effect of crystallization of melts of a few A 2 B 6 compounds have been determined.These properties are important for practice of A 2 B 6 single crystal growth from the melt.

Residual Bias Removal in HST NICMOS Images . Bushouse H., Dickinson M., van der Marel R.P. in `Astronomical Data Analysis Software and Systems IX', Manset N., Veillet C., Crabtree D., eds., ASP Conference Series, Vol. 216, p. 531-534, 2000 . 2000. ... Software tools have been developed to allow observers to examine and correct NICMOS images for the presence of residual bias signal. The NICMOS detector bias can drift between and during exposures, due to small changes in temperature. ...

... It was found that the Sun lies 9?2 pc above the plane of hte Galactic disk in the direction of North Galactic pole and that F0-F9 stars contribute 0.0035 M /pc 3 to the density of the Galactic disk. ... We used this method to determine the scale height of the subsystem of F stars of the Galactic disk, Z 0 =160?10 pc. ... It is suggested that scale height of the metal-poor stars subsystem is due to the infall of the metall-poor intergalactic gas onto the disk. ...

Close binary systems of the RS CVn and Algol type are characterized by a highly variable radio emission, from typical flux densities of a few mJy during low-activity (quiescent) periods, up to 1 Jy during strong flares. The origin of this radio emission is attributed to the gyrosynchrotron mechanism. Several observations of these stars have shown an evolution of the radio spectrum during both the rising and decay phases of flares. ...
