We report results from analysis of the observations of the dipping low mass X-ray binary XB 1323−619 made with BeppoSAX and Rossi-XTE. The dust-scattered halo contributes significantly in this source, and the observation made with BeppoSAX on 1997 August was used to provide MECS radial intensity profiles at several energies. From these, the halo fractions were obtained and thus an optical depth...

Information and communication technologies (ICTs) are an integral part of our environment, their uses vary across generations among individuals. Today’s student population is made up “digital natives” who have grown under the ubiquitous influence digital technologies, for whom use ICT common whose daily activities structured around media use. The aim this study to examine impact skills on stude...

The abstract of the above-referenced article contains errors. The corrected abstract appears here. The Bereitschaftspotential (BP) is a slow negative-going cortical potential associatedwith preparation for volitionalmovement. Studies since the 1960s have provided evidence for a BP preceding speechrelated volitional motor acts. However, the BP associated specifically with phonation has not to da...

XMM-Newton archival observations of the Be/X-ray binary candidate RX J0103.6−7201 revealed pulsations with a period of ∼1323 s. This makes RX J0103.6−7201 the X-ray pulsar with the longest period known in the Small Magellanic Cloud (SMC). More than 150 X-ray observations of RX J0103.6−7201 by ROSAT, Chandra and XMM-Newton show flux variations by a factor of 50 on time scales of days to years. U...
