037-B327 is of interest because it is both the most luminous and the most highly reddened cluster known in M31. Deep observations with the Advanced Camera for Surveys on the Hubble Space T elescope provide photometric data in the F606W band, and also show that this cluster is crossed by a dust lane. We determined the structural parameters of 037-B327 by fitting the observed surface brightness d...
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...
