In this paper we present BeppoSAX and XMM-Newton observations of two long Gamma-ray bursts, the X-ray rich event of December 11, 2001 (GRB011211) and the hard and very bright event of November 21, 2001 (GRB011121). In both events we find evidence of a late X-ray burst, taking place several minutes after the prompt emission. In the November burst the spectrum of the X-ray burst is much softer th...
translation studies have become an accepted academic subject and books, journals and doctoral dissertations appear faster than one can read them all (bassnet and lefevere, 1990). but this field also brought with itself so many other issues which needed to be investigated more, in the heart of which, issues like ideology, ethics, culture, bilingualism and multilingualism. it is reported that ove...
Vibrational relaxation of methanol-d ~MeOD! in carbon tetrachloride has been investigated via ultrafast infrared pump–probe experiments. Exciting at 2690 cm, only the free O-D ~where the D is not H-bonded! stretching mode is initially populated. For MeOD mole fractions <0.025, a 2.15 ps single exponential decay is observed. At mole fractions >0.0375, the signal decays ~2.15 ps decay time! below...
