...into a tree's circulatory system through holes drilled into the tree at or just below the root "flare" at ground level. In experiments conducted on 7,500 trees last year and an anticipated 100,000 elms this summer by the Elm Research Institute of Harrisville, N.H., early test results indicate that Lignasan is 99% effective when used preventively-before the disease strikes-on healthy trees. But many plant scientists refuse to endorse the product until they know more about proper dosages, duration of protection and the chemical's effectiveness when used without other preventive measures-such...
Ripple control is aimed at saving generating costs by turning off water heaters twice a day during periods of peak consumer demand, when electricity is most expensive to produce. So far, ripple control has worked: according to test results, the system has saved roughly $60 a year per heater in electricity costs, a saving that Green Mountain Power (G.M.P.) has returned to participants in the experiment in the form of monthly $5 rebates...
...Leon H. Sullivan, pastor of the 6,000-member Zion Baptist Church in Philadelphia, who had just been chosen as the first black to sit on General Motors' 23-member board of directors. Sullivan's election was widely regarded-not least by Sullivan himself-as an important test of the idea that a black presence in the board room could make a giant corporation more sensitive to the needs of minorities. The 6 ft. 5 in. minister had already acquired a reputation for both militance and pragmatism, first by organizing boycotts that forced scores of Philadelphia businesses...
...test his theory, Riggio has been injecting gamma globulin from human placentas, which are usually discarded after delivery, into patients at the hospital's Rogosin Kidney Center. He hopes that the placental extract will transfer blocking antibodies into them. That then might encourage acceptance of new organs. A positive sign: when Riggio examined long-term transplant survivors at the center, he found that their acceptance of kidney grafts somehow appeared to have been enhanced by a biochemical mechanism similar to that postulated in pregnant women...
...Schweiker gambit failed. Sears also made the questionable decisions that kept Reagan out of such big-state primaries as New York, New Jersey and Pennsylvania, on the theory that powerful party organizations would ensure rich delegate harvests for Ford. Some Reagan supporters faulted Sears for making a floor test on a procedural matter (whether Ford should have had to name his running mate in advance) rather than an ideological issue like detente. When this second gamble failed, Reagan was through...
