The neutron excess of heavy fragmentation products is analysed in order to extract the excitation energy at the beginning of the evaporation stage of the reaction. The result gives indications for a break-up stage also in reactions in which heavy fragments are formed. The freeze-out temperature, determined with this approach, agrees with the value of about 5 MeV found in light fragment producti...

Whether gamma-ray bursts are highly beamed or not is a very important question, since it has been pointed out that the beaming will lead to a sharp break in the afterglow light curves during the ultra-relativistic phase, with the breaking point determined by Γ ∼ 1/θ 0 , where Γ is the bulk Lorentz factor and θ 0 is the initial half opening angle of the ejecta, and such a break is claimed to be ...

purpose: to evaluate the underlying causes of rhegmatogenous retinal detachment (rrd) in eyes operated for this reasion. methods: out of 1473 patients who underwent retinal detachment surgery, records of 369 patients were randomly selected and evaluated for the types of retinal breaks, the underlying disorders, and location of breaks. results: fifty-two percents of patients were less than 50 ye...

We propose a model checking method and tool that integrates state abstraction techniques for the automatic proof of a stability property for hybrid systems called region stability. It is based on a new notion of snapshots which yield characteristic discretizations of trajectories. We have implemented the tool and applied it to solve a number of verification problems, including the fully automat...

This study aims to gain knowledge about the experiences of girls who are victims violence and exploitation from parents. research was conducted in Somba Opu Sub-district, Romangpolong Village, Indonesia. Post-positivism paradigm used as basis because its advantages allowing researchers uncover process perpetrated by parents against that occurs repeatedly. Data collected means in-depth interview...

It is widely believed that gamma-ray bursts are produced by a jet-like outflows directed towards the observer, and the jet opening angle(θj) is often inferred from the time at which there is a break in the afterglow light curves. Here we calculate the GRB afterglow light curves from a relativistic jet as seen by observers at a wide range of viewing angles (θv) from the jet axis, and the jet is ...
