Synthetic Atmospheres. Without oxygen animals smother; in pure oxygen they die also because of irritation and congestion in the lungs. Yet it must not be assumed that the best possible mixture for sustaining life is the natural atmospheric mixture of about 79% nitrogen, 20% oxygen and 1% other gases. After twelve years of smothering rats, monkeys and guinea pigs in various artificial atmospheres ranging from pure helium to nitrous oxide, Dr. John Willard Hershey of McPherson College reported that a mixture of 75% argon and 25% oxygen enabled the animals to get along as well as usual, that...
...Gotebo, Okla. 29 years ago, got his Ph. D. at 23 from Massachusetts Institute of Technology, and is now an assistant professor at Cornell. Of little interest to laymen, Dr. Kirkwood's work on the dielectric properties of gases under pressure and on polarization phenomena in methane, nitrogen and hydrogen provided invaluable working tools for chemists. Said the award committee: "He succeeded in instances where older and more experienced men of proved ability have failed to arrive at definite results...
...three years Biochemist William Gumming Rose and his associates at University of Illinois have fed artificially-made food to white rats. Of the ingredients in natural food only the proteins furnish nitrogen available for tissue building. Chemists have broken down the proteins into more than 20 simpler compounds called amino acids. Dr. Rose accordingly prepared and purified all the amino acids he knew of, fed them to baby rats together with synthetic carbohydrates, fats, salts and vitamins. Something was lacking. The animals failed to grow, wasted away, died. Then Dr. Rose succeeded in isolating another protein component: alpha -amino -beta...
...tampered with, Dr. Robert Williams Wood of Johns Hopkins exhibited a lantern slide depicting the impression of an apple leaf driven into solid steel by guncotton, declared the detonation in a tube of nitroglycerin proceeds at four mi. per sec., described a new explosive, iodide of nitrogen, which is so skittish that the landing of a housefly sets...
...instantaneously. It has two kinds of uses: cutting metal, as in scrapping locomotives, battleships; welding metal, in which the oxyacetylene flame fuses the parts to be joined together. Air Reduction is so called because it reduces air-that is, it separates air into its major components, primarily oxygen and nitrogen...
