ABSTRACT
We model neutrino emission from a newly born neutron star subsequent to a supernova explosion to study its sensitivity to the equation of state, neutrino opacities, and convective instabilities at high baryon density. We find the time period and spatial extent over which convection operates is sensitive to the behavior of the nuclear symmetry energy at and above nuclear density. When convection ends within the protoneutron star, there is a break in the predicted neutrino emission that may be clearly observable.
ABSTRACT
Tonsillectomy is a painful procedure with discomfort continuing for days after the operation. We investigated whether topical application of a neurolytic agent (ethanol) to the tonsillar bed following dissection could provide long-term analgesia. Sixty-four patients undergoing tonsillectomy were randomized using matched pairs, to receive topical ethanol applied to the operative site, or saline for three min, in a double-blind study. Endpoints included self-reported pain using a pictorial pain scale, analgesia consumption adjusted for body mass, and weight loss. Follow-up continued until day 7 post-operatively. Both groups received the same analgesic protocol including infiltration of the operative site with ropivacaine. There were no significant differences in pain scores, analgesia requirements or weight loss between groups for any time period. The incidence of severe pain was significantly greater on the third post-operative day compared with day 1 and 2 (p = 0.0096). Topical application of ethanol does not reduce post-operative pain.
