...also far easier to supply from the sea via the Perfume River. The U.S. and the South Vietnamese army have some 20,000 men within a dozen-mile radius of Hué. They hope that Giap will try to take the city again...
...gain insight into possibly harmful effects, Oyama has been raising mice and rats in 4-and 8½-ft. radius centrifuges that create artificial gravities from twice to 4.7 times normal and spin continuously except for brief intervals when they are shut down to clean cages and replenish food supplies. When the test animals are finally removed and returned to the normal gravity of earth, their experience is roughly equivalent to that of astronauts suddenly subjected to weightlessness or to a fraction of terrestrial gravity...
Expanding the gravity studies, Oyama and NASA Biologist William Platt have begun to use a new 26-ft.-radius centrifuge that can be supplied with food and cleansed of waste while it is running. On it, generations of rodents can be born and spend their entire lives under uninterrupted higher G. loads. From the responses of test animals-eventually including primates-Oyama hopes to predict the effects on astronauts of space trips that last for months and even years...
...stopped, after three hours and eleven minutes, Egypt had only one small oil refinery left-in Alexandria, 175 miles away. The two Suez plants were virtually demolished. Fireballs from exploding oil tanks could be seen 25 miles away, their light turning the desert night into vivid day for a radius of five miles around, their heat felt half a mile away. Egypt, its economy already in ruins as a result of the June war, had been dealt a staggering blow...
...only major steel producer based in Chicago, Inland has long capitalized on the lucrative Midwest steel market. With all its production concentrated at its huge Indiana Harbor complex in nearby East Chicago, the company sells 70% of its output within a 200-mile radius. In recent years, however, other major steelmakers have rapidly expanded their Chicago-area operations-and Inland has lately been feeling the pinch...
