We present a photometric study of the optical counterpart of the long-duration Gamma Ray Burst (GRB) 030725, which triggered the HETE FREGATE and WXM instruments on July 25th, 2003, and lasted more than 160s. An optical counterpart was identified at the Bronberg Observatory in South Africa about 7 hours after the burst occurred. The optical afterglow (OA)(More)
OBJECTIVE To evaluate a community-based educational intervention to improve wound-care practice, and thereby reduce the costs of care, in four communities in Denmark. METHOD Annual wound care audits recorded patients' ages, the number and types of wounds being treated, wound duration (days unhealed), frequency of dressing changes and nurse time per(More)
We present optical and near-infrared follow-up observations of the X-ray flash (XRF) of 2003 July 23. Our observations in the R band cover the temporal range from 4.2 hr to 64 days after the high-energy event. We also present the results of multicolor imaging extending to the K band on three epochs. The light curve of the R-band afterglow the first week(More)
Microlensing is the only known direct method to measure the masses of stars that lack visible companions. In terms of microlensing observables, the mass is given by M = (c 2 /4G)˜ r E θ E and so requires the measurement of both the angular Einstein radius, θ E , and the projected Einstein radius, ˜ r E. Simultaneous measurement of these two parameters is(More)
