Sir: In recent years, a number of new parenteral cephalosporins with a broad spectrum of antibacterial activity and a high stability against various /Mactamases have been reported1}. Most of them have a 7j5-[(Z)-2-(2-aminothiazol-4-yl)-2-alkoxyiminoacetamido] side chain, such as ceftizoxime (CZX) and ceftazidime (CAZ). They show excellent activity against Gram-negative bacteria and moderate act...
We independently redetermine the reddening and age of the globular cluster 037-B327 in M31 by comparing independently obtained multicolour photometry with theoretical stellar population synthesis models. 037-B327 has long been known to have a very large reddening value, which we confirm to be E(B − V) = 1.360 ± 0.013, in good agreement with the previous results. We redetermine its most likely a...
We present variability and multi-wavelength photometric information for the 933 known quasars in the QUEST Variability Survey. These quasars are grouped into variable and non-variable populations based on measured variability confidence levels. In a time-limited synoptic survey, we detect an anti-correlation between redshift and the likelihood of variability. Our comparison of variability likel...
