JOHN GARY SINGS YOUR ALL-TIME FAVORITE SONGS (RCA Victor). He sounds like Muzak with words-a bland, clean-cut voice that has made him a favorite with the over-35 ladies who sent his album sales soaring. All the old standards (Autumn Leaves, Night and Day, Star Dust, Smoke Gets in Your Eyes) seem to get the same beat and treatment, making them interchangeable...
...Bugs. To rid Voyager of its terrestrial bugs, contractors will be required to build spacecraft parts in "clean" rooms like those where many delicate instruments are now produced. Final assembly will take place in an ultraclean room, where living contamination will be reduced to as little as a thousandth of what is allowed in clean rooms. At the same time, all of Voyager's exposed surfaces will be decontaminated with ethylene oxide, a colorless gas that is deadly to microorganisms. Finally, the spacecraft will be placed in an airtight, teacup-shaped canister and baked in a giant oven...
Every oil known to science has failed. As soon as the metals rub themselves clean, molecules begin moving in both directions across the interface, the area of contact between the two metals. The "seizure" that results is as effective as a weld. Even machining is difficult. When a steel cutting tool is used on stainless steel or titanium, it sticks to the piece it is shaping and cuts out rough chunks instead of smooth chips...
...problem the surgeons faced was familiar. An artery consists of two inner layers and a "backup" outer layer which the flowing blood normally never touches. In arteriosclerosis, a fatty substance hardens along the inner layers and clogs the blood flow. The trick is to clean, remove or bypass those inner layers. Surgeons once commonly slit open the artery along the length of the diseased portion and scraped out the offending matter; more recently they have been bypassing or removing the entire section and replacing it with a synthetic graft...
...distinguish the piddlers from the real students, Hershey believes that it may be necessary to return to the system of national examinations and class ranking used during the Korean war. But he would rather see the colleges "clean their own stables." Although he is a trustee of his alma mater, Tri-State College, Hershey's philosophy of education was influenced more strongly by his early life on an Indiana farm and his long career in the army, than his days in the classroom...
