HFCE0X Brandon Jones, safety officer for Edgewood Chemical Biological Center (ECBC) turns a valve on the upper trailer deck releasing sodium hydroxide (NaOH) to the main trailer deck of MV Cape Ray (T-AKR 9679). The NaOH is used to balance the pH of the byproducts of the Field Deployable Hydrolysis System (FDHS) for storage aboard Cape Ray until off loaded in Finland or Germany for further destruction. Cape Ray is tasked with the neutralization of specific chemical materials from Syria in accordance with the Organization for the Prohibition of Chemical Weapons (OPCW) guidelines while operating in int

2AJ19CG The Journal of biological chemistry . Fig. 1. Bence-Jones protein. Recrystallized three times. acetic acid, as described above, could not be crystallized. Whensmaller quantities of acetic acid were used in the precipitation,some crystalUzation occurred. 25 cc. of urine were precipitatedwith 12.5 cc. of sodium sulfate after adding 3 cc. of glacial aceticacid. The pH was roughly 5. The precipitate was removed bycentrifugation and dissolved in a small quantity of water with theaid of a little sodium hydroxide. The solution was slightly acidi-fied, seeded, and allowed to stand at room temperature.
