    The March 11, 2011, earthquake and tsunami that occurred in Japan followed by the nuclear crisis at the Fukushima Nuclear Complex are described. The report focuses on the damage caused by the earthquake and the resulting effects of the nuclear meltdown at the Fukushima Daiichi Nuclear Plant and subsequent evacuations of people from an exclusion zone around the reactor. The effect on animals is not addressed but the Fukushima disaster is compared to the disaster in the US caused by Hurricane Katrina. Both of these disasters had substantial impacts on animals and their human caretakers and represent something of a watershed in how both countries address the issue of animals in disasters

    Molecular modeling of temperature dependence of solubility parameters for amorphous polymers

    A molecular modeling strategy is proposed to describe the temperature (T) dependence of solubility parameter (δ) for the amorphous polymers which exhibit glass-rubber transition behavior. The commercial forcefield “COMPASS” is used to support the atomistic simulations of the polymer. The temperature dependence behavior of δ for the polymer is modeled by running molecular dynamics (MD) simulation at temperatures ranging from 250 up to 650 K. Comparing the MD predicted δ value at 298 K and the glass transition temperature (Tg) of the polymer determined from δ–T curve with the experimental value confirm the accuracy of our method. The MD modeled relationship between δ and T agrees well with the previous theoretical works. We also observe the specific volume (v), cohesive energy (Ucoh), cohesive energy density (ECED) and δ shows a similar temperature dependence characteristics and a drastic change around the Tg. Meanwhile, the applications of δ and its temperature dependence property are addressed and discussed
