Authors: V.A. Marsakov , Yu.G. Shevelev , . Journal: 1988, Astron Zh. ... Absolute magnitudes, metallicities, effective temperatures, surface gravities, distances, and tangential velocities are calculated for 5498 F stars with homogeneous data on uvby photometry and proper motion, and placed within 80 pc from the Sun. Components of space velocities, eccentricities of galactic orbits, perigalactic and apogalactic distances, and maximal remotness from galactic plane are presented for 1787 stars. ...

... We present the first results of an extensive near infrared survey of galactic and OH masers in high--luminosity star forming regions (SFR) aimed to see if there are near--infrared (NIR) sources directly associated with the masers. ... Although not in all sources there are high sensitivity--high resolution radio continuum observations, only few of the K--band/maser sources are closely associated with known ultracompact (UC) Hii regions. ...

This program, termed the ROSAT Bright Survey RBS, is to more than 99.5% complete. ...

... We catalog 1457 new discrete radio sources down to flux densities of <=5 mJy an are 95% complete at 20 mJy. A detailed comparison of all radio sources from our complete survey in this longitude range with the IRAS Point Source Catalog proveds classification for 13% of the objects, including 159 compact HII regions, and nearly 100 planetary nebulae over 70 of which are newly identified. ...

Titles and abstracts. ... Bernard Leclerc; On the dual canonical basis (old and new) . Around 1991, Lusztig, motivated by earlier works of Gelfand and Zelevinsky, introduced a "canonical basis" of the coordinate ring C[N] of the maximal unipotent subgroup N of a simple algebraic group G. This basis was in fact the specialization as q tends to 1 of the dual canonical basis of the quantum enveloping algebra U_q(n) (where n = Lie(N)). ...

The Tunguska impact event and beyond . ... 50 (1), 18-26 (2009) . ... Current strategies for dealing with the impact hazard are geared towards the detection and deflection of near-Earth asteroids, which typically have approach speeds ~20 km/s and involve decades of warning. ... Warning times are then measured in months or days, and characteristic approach speeds are ~55 km/s. Concentrations of sub-kilometre debris in meteor streams may also be a significant regional hazard. ...
