...soul of the new machine is a ferocious 380-h.p. V-8 engine that experts say is the most sophisticated ever built. The aluminum-alloy engine boasts 32 valves, four for each cylinder, and an innovative air-intake system that can sip oxygen from a single narrow throttle valve or suck it full blast from a wide-mouth intake, depending on how sharply the driver presses the pedal to the metal. Other high-tech bells and whistles include a slick six-speed computer-assisted manual transmission and a suspension system that automatically adjusts shock absorbers to the speed...
...stakes cooperation is being seriously compromised by the nuclear $ issue. Last month, long after the schedule for Armacost's visit was completed, Arshad Pervez, a Pakistani native who holds Canadian citizenship, was arrested in Philadelphia and charged with trying to export to Pakistan 25 tons of a special steel alloy used in the enrichment of uranium for nuclear weapons. A federal grand jury has since indicted both Pervez and a resident of the Pakistani city of Lahore, retired Brigadier Inam ul-Haq, for conspiring to illegally export strategic materials. U.S. investigators suspect that the Pakistani government is behind the illicit...
Maraging 350 steel is a special steel alloy used in the enrichment of weapons- grade uranium. After a 20-month undercover investigation, federal officials in Philadelphia arrested Arshad Pervez, a Canadian of Pakistani origin, on charges of attempting to export the alloy. The apparent destination was Pakistan, which has repeatedly denied charges that its nuclear facility at Kahuta is intended to produce weapons. Democrat Stephen Solarz of New York, chairman of the House Subcommittee on Asian and Pacific Affairs, criticized the Pakistani government of President Mohammed Zia ul-Haq for showing "blatant disregard" for U.S. antiproliferation laws...
...until the 1950s that scientists discovered alloys, such as niobium tin and niobium titanium, that keep their superconductivity in the presence of intensely strong magnetic fields. And it was not until the '60s and '70s that the manufacture of large superconducting magnets became standardized. But progress toward the other goal of superconductivity researchers, pushing the phenomenon into a practical temperature range, was even slower. By 1973, some 62 years after Kamerlingh Onnes had found superconductivity in mercury at 4.2 K, scientists had upped the temperature to only 23 K, using an alloy of niobium and germanium. After 1973: no improvement...
...much sought-after goal proved to be elusive. In the early 1970s scientists found an alloy of niobium and germanium that lost all resistance at 23 K. Then, last April, a group at the IBM Zurich Research Laboratory in Switzerland announced development of a compound of barium, lanthanum, copper and oxygen that appeared to begin the transition to superconductivity...
