The effect of rate on the brittle-ductile transition of polymers can be given by an Arrheniustype equation with activation energy between those of 01 and p transitions and given by where Eb is the activation energy for brittle-ductile transition, E , is that for a transition, Ep is that for / 3 tran

The ductile-brittle transition temperature for bend specimens of recrystallized powder metallurgy molybdenum has been shown to be lowered from 50Β°C to 2Β°C by the application of a hydrostatic pressure of -20,000 psi (~1.4 kbar). The pressure medium was kerosene. The samples were obtained from 0.020
Both the melting and the crystallization d.s.c. thermograms for these paraffins exhibit two major peaks, a and /I, corresponding to the liquid-solid and solid-solid transitions. At the same rate of temperature change, the shape and peak height of the melting endotherms differ considerably from those
## Abstract Frozen mouse eggs were examined to determine the effects of low temperatures, concentration of cryoprotective agents and cooling rates on their survival, fertilizability in vitro and subsequent development. Dimethyl sulfoxide administered at 1.5 M concentration was found to be the most
