Optical Observations of SBS1520+530 at TUG

2007
We present the light curves of the components of gravitationally lensed source SBS1520+530 in Rc band, obtained during the interval 2001-2005 with the 1.5 m Russian-Turkish Telescope RTT150 at TÜBITAK National Observatory of Turkey. The time delay of brightness fluctuations between the two components of the gravitationally double-imaged quasar ...

Spectrophotometry of the QSO NRAO 530

Publications of the Astronomical Society of the Pacific, 1984
Spectrophotometry of the QSO NRAO 530 with the KPNO Cryogenic Camera is reported. A redshift of 0.902 is determined from the H-beta, H-gamma, and 3727 A forbidden O II emission lines, confirming a redshift that had been based on a single line, the 2798 A Mg II.

Interaction of the 530 ribosomal site with regions of mRNA

Biosystems, 1998
We evaluated the energetic stability of all possible 10-base fragments of the small subunit (SS) rRNA with a large ensemble of mRNAs. Results show that the 530 loop is the only conserved region that interacts favorably around the start codon as well as the elongation region of messengers.

Bending of Jets in the QSO NRAO 530

Chinese Journal of Astronomy and Astrophysics, 2008
We present radio images of NRAO 530 on scales ranging from pc to kpc. The observations include the EVN at 5 GHz, the VLBA at 1.6, 8.6 and 15 GHz, the MERLIN at 1.6 and 5 GHz, and the VLA at 5, 8.4, 15, 22, and 43 GHz. The VLBI images show a core-jet structure with an oscillating trajectory on a scale of about 30 mas north of the strongest compact ...

The well-baby care of 530 infants

The Journal of Pediatrics, 1966
A group of 530 healthy infants were studied in regard to reactions to diphtheria,pertussis, and tetanus (DPT) immunization and smallpox vaccination, feeding and behavioral habits, and sleep patterns during the first 2 years of life. The incidence of reactions following DPT immunization and smallpox vaccination were 19.8 per cent and 20.1 per cent ...

Takayasu arteritis in China: A report of 530 cases

Heart and Vessels, 1992
A total of 530 patients with Takayasu arteritis were studied. Among 346 patients who were diagnosed by aortography, the female to male ratio was 2.9 to 1, and the age of onset ranged from 5 to 45 years. Three hundred and eighteen (60%) patients with secondary hypertension, including renovascular hypertension in 281, and 197 (37.2%) with pulseless ...

A Dramatic (and Invisible!) Flare in NRAO 530

1996
3 mm λ VLBI observations of the extremely flat spectrum QSO NRAO 530 at the peak of its brightest recorded flare show a resolved core only slightly changed from its pre-outburst state. Observations with Haystack, Kitt Peak and Owens Valley observatories in April 1994, prior to the onset of the flare found a single component with T b = 8 × 1010 K.
