Show Angiography Alternative University of Utah Medical Center radiologists have developed an alternative to the most commonly used type of angiography which appears to be safer, more accurate, less expensive and easier to implement than any technique currently available to study the anatomy of arteries.

He predicts an increase in industrial demand from the current 77 million tons annually to 90 million tons by 1985. Detailing export market conditions, he said that many of these problems facing U.S. utility and industrial users are affecting European and Far East concerns as well. The optimistic outlook for the stream coal export market to Europe and the Pacific Rim countries will be dependent on economic growth, competiton from other coal-producing countries, political stabilty in the energy scene and inflation. "The cost of capital is giving potential coal users pause for thought," Cope said. "Because of inflation, costs to finance coal-fired plants have doubled, delaying expansion of coal-burning capacity worldwide." However, Cope belives that, similar to the U.S., many European countries "are very deter-, mined to back out oil." "The recent run-up in oil prices has cost European countries alone an extra $80 billion on the adverse side of the balance of payments. Backing out one million barrels of oil with 80 million tons of coal would save $6 billion at today's dollars," he said. Cope foresees global imports tripling, over the next 10 years to around 300 million tons. But the U.S. will have to face vigorous competition from coal port expansion in both Australia and South Africa, and from new mines in China, Colombia and western Canada. "It is important that we build modern coal export facilities and dredge our harbors to be able to accept the deeper draft vessels which our competitors will be able to load if we cannot," he said. He expects limited growth in the metallurgical coal market worldwide because of sluggish steel markets and new technologies which improves the efficiency of steel manufacturing in terms of coke requirements. According to Cope, coal consumption for both domestic and export markets is expected to increase from approximately 840 million net tons in 1981 to 1.2 billion tons in 1990. He believes these forecasts are encouraging and "would be the envy of most industries." |
