...exhibitors were buoyantly optimistic about magnesium's future. At 27? a lb., it is already cheaper by volume than aluminum (21.5? a lb.), can be easily welded, has a low electrical resistance and high heat conductivity, and resists weathering. And there is plenty of it. In every cubic mile of sea water, still the principal source of supply, there is an estimated 12 billion Ibs. of magnesium...
...power from the great Central Valley Project, which includes Shasta Dam. As part of his grand plan, Black has added ten new power plants, 200,000 miles of new transmission lines, 15,000 additional miles of distribution lines, and a 500-mile pipeline from Arizona that added 300 million cubic feet of natural gas daily to P. G. & E.'s supply of 400 million cubic feet. As a result, gross revenues, only $92 million when Black took over, last year hit $300 million...
...project, though originally provided by Pratt and Whitney, is now the property of the University. The supersonic tunnel has been used in a variety of different ways, such as the study of super-sonic shock waves.The axial flow compressor shown here supplies volumes of air up to 30,000 cubic feet per minute to the wind tunneis. Besides the axial flow compressor, there is a centrifugal compressor. Axial flow has largely taken the place of centrifugal flow on the power plants that drive modern jet aircraft. The large size of the above compressor can be observed by comparing it with...
...peasants, many of whom must still be convinced that President Magloire's favorite project is bon. Within 40 months, Haiti will have one of the world's highest buttress dams wedged in Peligre Canyon, 225 ft. high and 1,075 ft. wide, backing up some 328 million cubic meters of water. This water will flow 60 miles to the smaller intake dam at Canneau, where it will be diverted into canals to irrigate 80,000 acres of their land. Yet many black farmers cannot understand the need for the project. Used to primitive subsistence-level farming, they fear...
...single diagnosis of polio. That was impractical. Many physicians relied (and still do) on a microscopic examination of a droplet of fluid taken by puncture from the patient's spinal column. In normal, healthy fluid, there are few or no cells-not more than eight to the cubic millimeter. In victims of virus diseases like polio there may be 500 cells or more. This is still only a rough & ready test; half a dozen known viruses will produce the same result, and recent researches have turned up several viruses that seem...
