Nubian women seem happy about the move. Stone walls and concrete floors are a welcome change after a dusty lifetime of adobe and mud. Besides, there are movies, television, schools and clinics. As the Nubians file aboard the paddle steamer headed for Kom Ombo -loaded down with palm fiber beds, carved wooden chests, magical amulets, goats and sheep-they try to exorcise their grief of leave-taking by singing. One song runs: "The Nile is drowning Nubia and we must forget the past. The river brings life and the river brings. death...
...carried in the same space. It is also more powerful, producing a hotter flame (6,300 to 6,600° F.) and more thrust. The casing that restrains its pressure (800 to 900 lbs. per sq. in.) has been lightened by making it out of filament-wound glass fiber instead of metal...
Stage two, made by Hercules Powder Co., has new fuel, too, and 1,500 lbs. more of it. The casing, already of glass fiber in the A2, has been improved by a new lining to protect it from the new fuel's greater heat. Instead of nozzles for steering, it uses liquid Freon injected into the side of the gas stream...
Pulsed Beam. Working in an all but echoless 10-ft. by 13-ft. room lined with sound-absorbing wedges of glass fiber, Lockheed's scientists have set up a sort of searchlight with a sound generator in its throat. The researcher sits in a chair, covers his eyes with a blindfold and presses a button with his right hand. Out of the searchlight comes a beam of noise, 50 pulses per second, which sounds like a distant chorus of crickets and spring peepers. The mixed frequencies are higher than human ears normally hear, but the researchers have found that...
Last week the scaffolds were up in the hall once more. This time the back wall is to be velveted in absorbent fiber glass, the facing of the three terraces reshaped, the stage equipped with portable risers for the silent double basses...
