Super Rocket Targets . NPO MOLNIYA has been designing rockets-targets for over 30 years using the great experience in crea-ting anti-aircraft guided rockets (AGR) for C-25M. On the basis of B-300 anti-aircraft rockets which expired their service life, there were designed, tested and put into the serial production the following types of the rocket - ... The analogue of this system successfully passed the state tests with the ZVEZDA-4 rocket-target. ...

... Journal: 1973, Astron Zh., ... The isotopic shifts of helium spectral lines have been measured for four high velocity OB-stars and one standard star. The spectrograms were secured at 2.6 m reflector of the Grimean observatory, dispersion beging 8 / mm . All five stars did not show the systematic isotopic shifts. But three lines of 53 Ari have shown shifts which are in agreement with theoretical ones, but other helium lines did not show such shifts. ...

Polycyclic aromatic hydrocarbons in HII regions: correlation with metallicity . ... We have perfomed the aperture photometry of HII regions using infrared images from telescopes Spitzer and Herschel at passbands 3.6, 4.5, 5.8, 8.0, 24, 70 and 160 m. Emission of PAHs are observed at passbands 3.6 - 8.0 m, 24 m is emission likely of hot small particles and finally large particles are responsible for emission at 70 and 160 m. We determine abundances of PAHs using model of Draine Li (2007) . ...
