...General Hospital in Minneapolis, first to open a large Government-supported unit in the U.S., which has been in operation since May 1 this year. Once inside the pressurized chambers, Dr. Hitchcock reported, the hospital staff and patient share all the dangers of the deep-sea diver. There is nitrogen narcosis, or Cousteau's "raptures of the deep"-also known as "the martini effect"-caused by excess nitrogen; "oxygen ebullience," a kind of euphoria resulting from excess oxygen; and finally, "the bends" or "caisson disease," from too-rapid decompression...
Promoted to assistant professors of Physics are Louis N. Hand, who has investigated the properties of the nucleus revealed by electron scattering, and Joseph L. Snider, who has done research on the magnetic properties of the nitrogen nucleus. Hand, an Instructor since 1962, holds the B.A. (1955) from Swarthmore and the Ph.D. (1962) from Stanford. Snider, an instructor since 1961, holds the B.A. (1956) from Amherst and the Ph.D. (1961) from Princeton...
Daily, 10,000 tons of chemical compounds-hydrocarbons and nitrogen oxides-pour from 3.5 million exhaust pipes. When there is no breeze, and the exhaust-laden air is trapped in the mountain-rimmed Los Angeles basin, the bright Southern California sunshine, which could be expected to burn off a simple, old-fashioned fog, goes to work on the invisible gases until a giant photochemical reaction takes place. The pallid, evil-smelling vapor that results is known as smog...
...delay-free smoothness of the launch was largely because Titan II, a practical, dependable military rocket, does not use troublesome liquid oxygen. Instead it burns storable liquid fuels (a mixture of hydrazine and unsymmetrical dimethylhydrazine with nitrogen tetroxide as oxidizer) that are "hyper-golic," ignited spontaneously on contact. It is much more powerful than the Atlas that launched the manned Mercury capsules, having 430,000 Ibs. of thrust at takeoff instead of 360,000, and 100,000 Ibs. of thrust in its second stage. The dummy Gemini capsule, weighted with ballast and instruments, was more than twice as heavy...
Natural gas is also a prime source of anhydrous ammonia, the key ingredient in nitrogen fertilizers. Because of its vast natural gas reserves-and its generous sources of phosphate, potash and other plant foods-the U.S. is the world's prime supplier of fertilizer. About 10% of the U.S. output is exported, mostly to developing nations that need more food for their rapidly expanding populations-Korea, Mexico, India and Chile...
