Thermal fission rate around super-normal phase transition
Using Langer's method, we discuss the temperature dependence of
nuclear fission width in the presence of dissipative environments. We introduce
a low cut-off frequency to the spectral density of the environmental
oscillators in order to mimic the pairing gap. It is shown that the decay width
rapidly decreases at the critical temperature, where the phase transition from
super to normal fluids takes place. Relation to the recently observed threshold
for the dissipative fission is discussed.Comment: 12 pages, Latex, Submitted to Physical Review C for publication, 3

Injuries due to foreign body aspirations in Georgia: A prevention perspective
Background: Suffocation due to foreign bodies (FB) is a leading cause of death in children aged 0-3. No data from the former U.S.S.R. are available in the international scientific literature. Methods: Consecutive patients admitted at the Iashvili Central Children Hospital in Tbilisi, Georgia from 1989 to 2011 were analyzed. Injuries in the upper airways due to foreign bodies' inhalation were collected and compared with the Susy Safe Registry and the pooled estimates of the meta-analysis. Results: 2896 cases were collected. Distribution of injuries in children younger than 3 years was significantly higher than in the Susy Safe Registry and in the "High-Income" countries in the meta-analysis. Percentage of injuries due to organic objects (86%) was significantly higher than in published data. Conclusions: Since Georgia is not showing any substantial difference, both in epidemiology and treatment of foreign bodies injuries, as compared to the other case series, translation of public health initiatives from other most advanced prevention experiences is possible and it is likely to be effective.
