Air Max 1 peritectically at 598 ± 1 °C
The constitution of the Sn-Sr system from pure tin to 35 at.% Sr was determined using differential thermal analysis, X-ray analysis, metallography and microprobe Air Max 1 analysis. In contrast with the findings in the literature, Sn3Sr is found to melt peritectically at 598 ± 1 °C with a liquid phase containing 20.3 at.% Sr. Buy Nike Air Max 95 The stoichiometry of the tin-rich phase in equilibrium with tin was determined to be Sn4Sr; it also melts peritectically, at 334 ± 4 °C, with a liquid phase containing 4.0 at.% Sr. The Sn-Sn4Sr eutectic temperature is 230 ± 2 °C with the eutectic liquid containing 1.0 at.% Sr. Buffalo bull semen samples were diluted (1:40) in Cornell University extender, Cornell University-16 extender, egg yolk citrate, citric acid whey, lactose and tris diluents. These were frozen in liquid nitrogen (−196°C), thawed at 50°C and the effect of 6mM caffeine citrate on the postthawed motility was evaluated. Caffeine citrate increased the postthawed motility of the spermatozoa in different diluents from 25% to 100%. Highly significant stimulation due to caffeine citrate was observed in samples having low postthawed motility (upto 39%) irrespective of the diluents used.
