...cylinder-10 ft. long and 5 ft. in diameter-will be pulled from the booster by the Apollo command ship. In position between Apollo and Soyuz during the docking, it will act as an essential decompression chamber for men passing from Soyuz's "normal" atmosphere of 70% nitrogen and 30% oxygen (at sea-level pressure of 14.7 Ibs. p.s.i.) to Apollo's low-pressure (5 Ibs. p.s.i.) atmosphere of pure oxygen.* If they did not stop in the chamber on the way from Soyuz into Apollo, spacemen would get the bends-the sometimes fatal buildup of nitrogen bubbles...
Storecard. Even at the present level, however, electric-power plants are a major source of air pollution: 50% of the sulfur dioxide in the atmosphere, 20% of the nitrogen oxides, 20% of the soot and ash. Can technology reduce this pollution? Yes, according to a new study by the Manhattan-based Council on Economic Priorities, a nonprofit organization that reports to concerned investors (churches, universities, foundations) on subjects involving corporate responsibility. But many utilities have been slow to install proven and existing equipment, the study says, or to develop alternative power sources...
...study said, 71% of the plants involved had inadequate controls on soot and 81 % had no controls at all on nitrogen oxides, a cause of emphysema. The utilities quickly attacked the report ("unscientific, distorted, partly false, and highly prejudiced," said the head of American Electric), but the plant-by-plant survey leaves no doubt that there is still much room for improvement-both in present production and in planning for the future...
...deposit is carefully analyzed and a sampling of the sperm counted in an electronic device to establish the semen's degree of fertility. The semen is then stored in thin plastic "straws," labeled, placed within a cigar-shaped aluminum container and chilled to -321° F. in liquid nitrogen. Sperm banks are inordinately careful to guard against unauthorized use of their resources. Donors are blood-typed, for instance, because certain substances are common to both individual sperm and blood and thus serve to identify "ownership" of the substance...
...fishing town of Minamata, mercury poisoning has killed 46 villagers and paralyzed or blinded more than 70 during the past two decades--yet the Nippon Nitrogen Company continues to discharge its mercury wastes into the bay. The government has mirrored the company's indifference. Japan's Economic Planning Agency suppressed a report which demonstrated that the plant's effluents are lethal...
