objective: to compare the effectiveness of group training of stress management with cognitive-behavioral therapy (cbt) in reducing depression, anxiety and stress perceived among hiv-positive men. methods:inthis semi-experimental study, three groups of hiv-positive men (cbt group, stress management group, and control group) including 15 patients in each group were compared regarding depression, ...

The recent discovery of rotating radio transients and the quasi-periodicity of pulsar activity in the radio pulsar PSR B1931+24 has challenged the conventional theory of radio pulsar emission. Here we suggest that these phenomena could be due to the interaction between the neutron star magnetosphere and the surrounding debris disk. The pattern of pulsar emission depends on whether the disk can ...

A transient radio source in the direction of the Galactic Center, GCRT J1745-3009, exhibited 5 peculiar consecutive outbursts at 0.33 GHz with a period of 77.13 minutes and a duration of ∼ 10 minutes for each outburst. It has been claimed to be the prototype of a hitherto unknown class of transient radio sources. We interpret it as a transient white dwarf pulsar with a period of 77.13 minutes. ...
