Observations of radio wave phase characteristics on a high-frequency auroral path

High Cadence Radio Observations of an EIT Wave

Sensitive radio observations of the 1997 September 24 EIT wave show its velocity to be 830 km s−1. The wave first appears a short distance from the flare site, and its trajectory projects back to the flare site at the peak of the impulsive phase. The radio spectrum appears to be consistent with optically thin coronal emission rather than chromospheric emission. The observed radio brightness tem...

[Treatment of trichiasis with high-frequency radio wave electrosurgery].

PURPOSE Trichiasis is an acquired condition in which the eyelashes are directed posteriorly, touching the surface of the cornea. It poses a complex therapeutic problem. Despite several therapeutic options (epilation, electroepilation, cryotherapy, laser ablation and standard surgical techniques), relapse is frequent. METHODS A prospective, nonmasked study was conducted to determine the effica...

Low Frequency Radio Observations Of W51 Complex

W51 is a giant radio complex lying along the tangent to the Saggitarius arm at a distance of about 7kpc from Sun, with an extension of about 1◦ in the sky. It is divided into three components A,B,C where W51A and W51B are regions consisting of many compact HII sources.We have made continuum radio observations of these HII regions of W51 complex at 240,610,1060,1400 MHz frequencies using GMRT.
