...drilling equipment, machinery and electronic gear, including computers. The Russians have been eager for loans and technological know-how, and so far they have got some of both. Only in May Nixon intervened with the Export-Import Bank to approve a $180 million loan for eight Soviet ammonia fertilizer plants and the attendant gear to move the fertilizer to distribution centers. Partially because of the Jackson amendment, however, Nixon has not been able to deliver on his other promises for loans and tariff concessions. "My firmness has resulted in some movement," Jackson says, defending his stand. "The only real charge...
...latest emergency that bodes ill for food prices is the serious fertilizer shortage. Supplies of natural gas, from which many fertilizers are made, have shrunk along with those of fuel. Speaking of a key fertilizer known as anhydrous ammonia, Warren Dewlen, chairman of the Fertilizer Institute, says: "Inventories are only half of what they should be at this time, and the outlook for improving the situation is dim." Some farm experts believe that the lack of fertilizers alone could cut crop yields by as much as 20%, worsening the shortage crunch in raw agricultural products...
...link is proving to be a bonanza for U.S. firms; the Chinese import nearly 15 times as much from the U.S. as they export. Among the biggest ticket items to date are some 4,000,000 tons of grain, ten Boeing 707 jetliners valued at $150 million, and eight ammonia plants to be built by M.W. Kellogg Co. for $200 million. The Chinese are also anxious to do business with giant American oil companies such as Exxon, Mobil and Caltex, and makers of petroleum exploration and drilling equipment, including U.S. Steel International, Phillips Petroleum and Baker Oil Tools. Some analysts...
Comets, in fact, are nowhere near as large as planets. Their central structure, or nucleus, is usually no more than a few miles in diameter; it is believed to consist largely of frozen gases-mainly water vapor, methane, carbon dioxide and ammonia, and perhaps some hydrocarbons-and dust particles. That, at least, is the commonly accepted "dirty snowball" theory, originally proposed by Harvard's Whipple in 1950. But there are those who take exception to Whipple. British Astronomer Raymond A. Lyttleton prefers his own "gravel-bank" theory, which holds that the cometary nucleus is really a loose mass...
...nucleus). M.I.T.'s Haystack Radio Observatory will try a similar experiment in reverse: it will study radio waves from a far-off radio source (possibly a quasar) after they pass through the comet's tail, in hopes of finding the spectral "signatures" of water or ammonia. If they succeed, the M.I.T. astronomers will have gone a long way toward confirming Whipple's icy-snowball theory...
