THE ARGUMENT AGAINST LONG EXTRAGALACTIC DISTANCE SCALE Gaseous discs of S0 -- Sd galaxies appears to be gravitationally stable or close to stability. Dependence of the gravitational stability parameter of gaseous disc $M_g/M_c$ upon the color index $(B-V)^0_T$ which reflects a relative number of young stars, is found. Here $M_g$ is total mass of gas in a galaxy, $M_c$ - mass of gas which corresponds to marginal stability of gaseous disc at distances from center. ...

Next: Upper Limits for Up: The Second EGRET Catalog Previous: Primary Catalog . As a result of the re-analysis of the Phase 1 data with the improved model of the diffuse gamma radiation, a number of the sources which appeared in the first EGRET catalog ([ Fichtel et al. 1994b ]) do not appear in this one (and conversely, some in the present catalog would have appeared in the first catalog using the improved model). ... These include 5 of the AGN listed in the first catalog. ...

Experimental rocket R-1A . To mature mass and operating characteristics of rocket R-1, its designers proposed to use an integral fuel tank and a warhead separated from the rocket at the ascent phase completion. In this case, only the ascent phase appeared to be rated for the launch vehicle and considerably more favorable regarding mechanical and thermal loads as compared to the atmospheric portion of the descent phase of the flight trajectory. ...
