The 11 km fringe visibilities of IRC ]10011 (\ CIT3) and IRC ]10420 have been measured at baselines ranging from 2 to 14 m with a two-telescope interferometer. The visibility data provide onedimensional proÐles of these two stars and their immediate surroundings with higher resolution in this spectral range than is presently possible with a single-aperture telescope. Spherically symmetric radia...

We present sub-milliarcsecond observations of SiO masers in the late-type stars IRC +10011 and χ Cyg. We have used the NRAO Very Long Baseline Array (VLBA) to map the 43 GHz (v=1, 2 J=1–0) and the 86 GHz (v=1, 2 J=2–1) SiO masers. All the transitions have been imaged except the v=2 J=2–1 in IRC +10011. We report the first VLBI map of the v=1 J=2–1 28 SiO maser in IRC +10011 as well as the first...

We report the first VLBI map of the 7 mm v=0 J=1–0 maser line of the 29 SiO isotopic substitution in the long period variable star IRC +10011. We have found that this maser emission is composed of multiple features distributed in an incomplete ring, suggesting that this maser is also amplified tangentially as already proposed in other SiO circumstellar masers. We present also the results for so...

bahram beizaie has a special attention to iran’s honorable old ages. he chooses one feature of the golden age “matriarchy” period and shows that in some of his plays. the purpose of this research is to talk about the dependence of heroines and iranian goddess, and to analyze this dependence in some of beyzaeis’ works. plays and screenplays that are considered in this study include: “saljuk istg...

Many advertisers (bidders) use Internet systems to buy display advertisements on publishers’ webpages or on traditional media such as radio, TV and newsprint. They seek a simple, online mechanism to reserve ad slots in advance. On the other hand, media publishers (sellers) represent a vast and varying inventory, and they too seek automatic, online mechanisms for pricing and allocating such rese...

Enterococcus faecalis is an opportunistic pathogen that causes serious infections in humans and animals and is also an important bacterium for dairy and probiotic supplement production. Therefore, bacteriophages infecting E. faecalis may be useful for phage therapy against multidrug-resistant strains or may threaten industrial fermentation. We isolated a virulent Siphoviridae bacteriophage, BC-...
