FF Aqr DW Period is significantly greater than typical value for DW type. According to Pojmanski [45] this star is DCEP-FU: variable. According to Sipahi et al. [263] it is one of the few binary systems which consists of the hot subdwarf and cool chromospherically active giant components. ... Belongs to long-period RS CVn systems, secondary is more massive and more larger (volume of the secondary is approximately 100 times larger than that of the primary component). ... So may be SA system? ...

... By undertaking a spectral and photometric investi­ gation of the central part of the bright elliptical galaxy NGC 759, we have found an optical counterpart for the circumnuclear molecular gas ring with the radius of # 3 ## (# 1 kpc) which was earlier reported by Wiklind et al. ... 2 Fig. ... More likely, this ring may be a consequence of a tidal encounter between the elliptical galaxy NGC 759 and a large spiral galaxy which was accompanied by a substantial gas accretion. ...

In the current situation international cooperation, both in form of joint non-commercial ventures and integration into global space market, is considered vital for sustenance of the national space capabilities. ... number of R&D programs . ...

Comment on J0513-2159 . Our image shows an extension to about 5 mas SE from the brightest feature. The EVN 8 GHz image by Dallacasa et al. (1998), with about five times larger resolution, shows an extension from the brightest feature roughly opposite to our direction. As noted by Dallacasa et al. (1998), the structure detected has a highly inverted spectrum, which, together with the reported variability in the source, could explain the structural disagreement. ...
