...will be a slow, carefully monitored journey. First, 6 million cu. ft. of nitrogen will be blown through the pipeline to purge air from the system, reducing the threat of oil-vapor explosions. Next, a cylindrical plug, called a "pig," will be shoved into the line. Finally, after a signal from Valdez, workmen will open valves at Prudhoe, allowing long-capped crude to fill the line behind the pig. The moving oil will push the pig through the 48-in.-diameter steel pipe at 1 m.p.h. As it goes, the cylinder will shove out of the pipe any refuse that...
...three candidates for president of the United Mine Workers, wipes the sweat from his brow and circles the spartan bathhouse of the Eccles mine near Beckley, W. Va., looking for another hand to shake. The miners, encrusted with coal dust and bathed in the harsh glare of mercury-vapor lamps, eye him as they change shifts at midnight. "Don't make no difference who gets elected," grumbles Jim Pavlik after Patrick passes by. "They all promise you everything and produce nothing...
...carries the impressive label "Cosmic Dust, Meteorite, and Lunar Studies Lab." In another basement lab two scientists tinker with an elaborate device that, when finished, will heat molecules so their spectra at temperatures above 2500 degrees Centigrade (4500 Fahrenheit) can be observed. At that temperature even iron becomes a vapor, as it is in stars...
...visiting scientist at the Center, has shown how the amount of radioactive carbon in tree rings can be related to sunspots. Increased solar activity leads to warmer climates, Eddy says, raising the radiocarbon content of the rings. Another group of astronomers, working with radio telescopes designed to detect water vapor in remote parts of our own galaxy, found they could also use the radio telescope to measure the amount of water vapor in the earth's atmosphere. The method proved cheaper and more accurate than previous techniques, like taking samples with rocket probes...
...exaggerated. Most scientists now believe that it would take a fleet of at least 100 SSTs to produce even a minimal greenhousing effect; no more than 16 Concordes are likely to be manufactured. Future generations of SSTs will probably be designed to emit much less water vapor. As for pollution, the plane's emissions fall within generally accepted levels. The available evidence does not substantiate the fears of ozone destruction. Compared with the thousands of U.S., Soviet and West European supersonic warplanes that crisscross the skies, the tiny Concorde fleet could not possibly have much impact on the ozone...
