The number of women serving in the military and deployed to active-duty is unprecedented in the history of the United States. When women became a permanent sector of the U.S. Armed Services in 1948, their involvement was restricted to comprise only 2

A precision of 99.5 per cent, or better, is obtainable for the determination of boric acid anhydride (50 to 150 mg per liter) in deuterium oxide or ordinary water solution; titrations may be performed with concentrations as low as 0.76 mg per liter.

Precision determination of deuterium (deuterium oxide) in aqueous mixtures were made by a pyenometer method over the range of 1 to 99 atom-% deuterium. The average deviation was ± 0.02 atom-%, deuterium. Absolute values of high-deuterium content sam

A sensitive reagent, methylene blue-PdCl 2 is applicable to the determination of smaller amounts of hydrogen in inert gases. Using this reagent, and a continuous gas-flow type of analysis, the range of the method is 0.1 to 10 parts per million hydrog

An improved method is described for the determination of micro-amounts of oxygen gas in argon, carbon dioxide, helium, hydrogen and nitrogen by the Winkler. procedure. The technique is such that a mean standard deviation of ± 0.33 ppm oxygen with a

This study was undertaken to develop a means of determining oxygen in zirconium which is present in a form other than that of zirconium oxide. The method described determines oxygen which is evolved as molecular oxygen when solid zirconium metal is d

The modified brady method is a rapid one, requiring only about one hour for the analysis, but requires large samples of gas, 5 to 20 liters. The precision of the method described here-in is ± 0.004 to ± 0.4 in the low range of oxygen-concentration

Tetrahydrofuran-water mixture is a satisfactory medium for polarographic studies of certain organic compounds. It is particularly adaptable for routine analyses becaues it may be purchased in a relatively pure form and any small amounts of impurities
