Chumbley explained that water vapor present in supposedly dry crystals of acetanilide reacted violently with chlorosulfonic acid and the mixture "exploded in my face." His burns were "nothing serious and will be completely healed in two weeks," he said...
Under traditional purification methods, salt or brackish water is either heated to a vapor and then condensed, leaving foreign matter behind, or else it is frozen into ice, thereby separating out the brine, and then remelted to obtain a pure product. The Ionics system, developed by Executive Vice President Walter Juda, does neither. It is an electrical process that exploits the natural attraction of opposite charges. Ionics uses a 4-ft. stack of 18-by-20-in. plastic membranes, 1/32-in. thick and 1/25-in. apart, between which the brackish water circulates. When voltage is applied across the stack, positively charged ions...
...tooth no longer bothering him, Nehru flew off to New Delhi to pack for his trip to the U.N. General Assembly this week. Behind him he left a vapor trail of the oldtime Nehru rhetoric. To correspondents he stressed the great similarity in "texture" between the culture of northern India and West Pakistan, with an old Harrow boy's knowledge of English poets quoted Samuel Taylor Coleridge to explain the peculiar persistence of Indian-Pakistani bitterness: "To be wroth with one we love/Doth work like madness in the brain...
...ended, they often find their way-as waste-into the air people breathe, the water they drink and the food they eat. Often invisible and immune to bacteriological attack, they damage plants, kill fish, slip undetected through sewage-treatment plants, and blanket entire cities with clouds of noxious vapor. Some, like sulphur dioxide, are clearly toxic-memorably so in the five-day siege of sulphurous smog in Donora, Pa. (pop. 13,000), which struck down 5,910 and killed 18 in October 1948. Others, doctors think, may have serious cumulative effects on human health-which will not show...
...earth's corona, Astrophysicist Shklovsky reasons, is mostly hydrogen which came originally from the earth's oceans. Water vapor works its way up from the lower atmosphere. When it reaches about 60 miles, its molecules are broken into oxygen and hydrogen by solar radiation. The hydrogen, being lighter, tends to rise, and above about 1,000 miles it becomes the main constituent of the atmosphere. Some of its molecules get hot enough and move fast enough to reach escape velocity and leave the earth entirely. Moscow's Professor Shklovsky believes that enough hydrogen has escaped in this...
