Veterans Day, then, is not only a day set aside each year for memorials to those who served and those who died; it is a time to remember those who die a little bit each day as they stand in an unemployment line, while Temporary Aircraft Runways Study Contracted to Utah State University For many years the military services have used temporary aircraft runways made by laying metal landing mats over the ground surface. However, 1970 prototype test landings of a pound C5A transport plane on such a mat caused the temporary tript to buckle. Mat panels were separated and thrown into the air. Some of the panels penetrated the airplane and endangered the life of the crew. Following that experience the U.S. Air Force contracted with the Engineering Experiment Station at Utah State University to begin testing the landing mats with scale models, rather than risk continued tests of the C5A itself. Using 17 scale models of metal segments linked together to make the landing runways, and a model landing gear, USU engineers have completed the tests. Their reports show how the temporary runways can be modified to improve the half-millio- n landing mat performance with reading the latest economic news. aircraft.

Accumulation of Lead In Humans May be Greater Than Blood Tests Show in blood vary widely with diet, and the standardmethod to detect lead poisoning by analyzing blood may be an unreliable index of lead exposure among the general population, according to a report at the recent .national meeting of the American Chemical Lead-level- s Society. Protein is the critical factor in the diet. Experiments in rats show that animals on a diet low-prote- in accumulate lead in the blood whereas those on a diet store the toxic metal in the bones and protein-ric- h tissues, said Dr. Augusta A. Mylroie, professor of chemistry at Chicago State University. If lead metabolism in children were analogous to lead metabolism in growing rats, it would be possible for children to absorb a considerable amount of lead, store it in the tissues, and yet have lead concentra- tions that are considered to be within the normal range, she explains in a summary of the research. On the basis of blood levels alone, these children would then be considered to have deceptively low levels of lead intake. On the other hand, children on a diet, exposed .to the same amount of lead could have cwey low-prote- in high blood lead levels. There is considerable controversy as to whether the continual increase in lead pollution poses a health hazard to the population at large. Our results imply that the accumulation of lead in the body may be more widespread in the general population than generally recognized from blood tests alone. Statistics show that lead poses a serious problem to a large number of urban children. Lead poisoning from lead-base- d paints in deteriorating housing can lead to mental retardation, neurological damage, and even death. On the other hand, blood levels in suburban children SBSass landing gear, weight of the airplane, was accelerated along a horizontal track and the then over the crest of a hill to gather speed. At about 30 miles per hour it left the cantilevered end of the track and touched down on the LEASED GRAPEVINE model runway. Then an operator riding the model braked it to a stop, just as an airplane would be handled on a e temporary runway. According to Prof. Blotter, the tests show at least three ways the temporary runways can be improved. First, they found that mat segments with an almost square (4 x 4.5 feet) geometry and dynamically more stable than rectangular segments such as the 2 x 12 foor segments than failed in the C5A test landing or a 2 x 9 foot variation. Second, they found that laying the segments the long way of the runway rather than across it improved the dynamic stability. Third, installing tension anchors at the touchdown end of the runway also helped keep the mat in place, and eliminated bow waves from forming. Using these modifications, the researchers were able to make hundreds of landings with the model landing gear without failure of the runway. Weve given the Air Force technical data on the dynamic reponse of the mat that can be used in coordination with military operations to make future plans, Prof. Blotter points out. The model study, at a funding level of approximately $300,000 also provides design analysis of future expedient airfield surfaces. full-siz- . Iv f Federal approval for the expenditure of some $325,000 in Community Development fund for three Salt Lake City projects was announced this past week by Mayor Conrad B. Harrison. The allocations are part of a' grant from the Department of Housing and Urban Development. Local officials distributed the funds earlier this year but were awaiting HUD authorization before Labor picketing at three Salt Lake plants is continuing while nearly 700 persons are idled by strikes.

A child in the suburbs who lives near a freeway, for example, and eats a high protein diet may show no signs of lead poisoning either in behavior or in lead levels monitored in the blood, t the same time, the exposure to lead from cars on the freeway may be just as great as the lead exposure in the city, she said.
