Co - localization of calcineurin and F - actin in dendritic spines

A copper-nickel alloy is remelted to form high quality ingots or slabs which are capable of undergoing hot-working in the "as cast" form by electroslag remelting the alloy under a flux composition prepared by fusing a mixture consisting essentially of from about 35% to about 75% barium fluoride and from about 25% to about 65% calcium fluoride, by weight.
