Known as xeroradiography, the process uses the same principles as an office copying machine. A prototype was first constructed in 1946 at the request of civil-defense planners, who hoped to duplicate X-ray plates that might be destroyed in the event of an atomic attack. Never put into full operation, the clumsy model was later acquired by Dr. John Wolfe of Hutzel Hospital in Detroit, a pioneer in the field of xeroradiography. His work with the machine eventually caught the attention of Dr. John Martin, a radiologist at St. Joseph Hospital in Houston. Martin and several colleagues convinced...
Selective Prejudice. New York City's Bellevue Hospital Center has separated its pediatric and psychiatric emergency facilities from its trauma section, installed a 16-bed intensive-care section, an X-ray unit and a computerized laboratory within yards of the emergency entrance. Beekman-Downtown, in the shadow of New York's City Hall, has similar facilities in its newly constructed emergency department, plus an unusual addition: a room with hoses and fans to wash down and aerate those who have been tear-gassed in demonstrations...
...being a liberal arts major. In an attempt to redeem liberal arts, my interviewer told me the suspense-filled story of "The Tiger and the Lady." Then I was told that the story of the tiger and the lady had the impact or even substance of talking about X-ray analysis. I regret that the acute importance of cocktail chatter had to be shown to me in this way, but I laugh because the Harvard guest feels so threatened by my presence. LISA KLEIN A Metallurgy major...
Later, on the homeward voyage, Worden conducted a more esoteric experiment. Pointing his instruments at X-ray sources far out in the galaxy, he recorded the emissions for clues that might be used to confirm the existence of "black holes"-weird, theorized remnants of huge, collapsed stars. He also awed earthlings-including his two daughters-by taking a televised 18-min. walk in deep space some 200,000 miles from earth to retrieve the exposed film cassettes from the service module's cameras...
...three base their finding on observations and X-ray photographs of 17 patients who volunteered to have their finger joints stretched on a specially designed machine. The tests showed that stretching increases the space between the finger bones, thus reducing pressure on the clear, viscous synovial fluid that lubricates the joints. This causes tiny gas bubbles to form within the fluid. As the pressure continues to decrease, these bubbles burst and release their energy as noise. The gas does not escape. Instead, as the joint returns to normal position, the gas is reabsorbed into the synovial fluid over a period...
