UNDER a pressure of carbon dioxide of 39.5 atmospheres, thermal dissociation of calcium carbonate takes place at 1,240°–1,242° C. 1,2 with the formation of a eutectic melt of lime and calcium ...

We show that raised concentrations of extracellular calcium ions shift the preferred mode of exocytosis to the kiss-and-run mechanism in a calcium-concentration-dependent manner.
