...critics complain that the industry has overexpanded. In the face of this criticism, most steelmen are now making capital outlays-at the rate of more than $1 billion a year- chiefly to modernize their plants, put in improvements that will produce better or less expensive steel. One example: the oxygen process, by which oxygen and gas are shot into a furnace to speed up the burning of impurities. An invariable but often unintended result is extra capacity: the oxygen process can raise capacity of furnaces 10% to 20%. The new processes also push some older equipment into reserve; about...
...massage a day will keep tension away; but if it is not feasible, six deep breaths two or three times a day will give tired tissues an oxygen lift, as will bending over and shaking arms and hands "until they tingle...
...either, given the right instruments. On a roof at Los Alamos Scientific Laboratory, six wide-angle lenses stare day and night at the sky. Each is linked to a filter that makes it blind to all light except a special kind that comes from the fluorescence of nitrogen or oxygen. If light of this unusual sort comes down from the sky, the rooftop apparatus at Los Alamos will ring an alarm that will sound around the world. It will mean that some nation has attempted a secret bomb test in space-and has been caught...
...tests above the atmosphere in 1958 taught that when a nuclear bomb explodes in a vacuum, about half of its energy goes into invisible X rays. These hit the atmosphere and make its oxygen and nitrogen fluoresce in characteristic wave lengths that can easily be distinguished from the spectrum of sunlight. When Los Alamos Physicist Donald R. Westervelt learned about this, he designed a detection system based upon it. A few dozen of his detectors spotted around the earth would be an adequate network. Some of them would always be under clear skies. In daylight they would detect...
...Circle of Willis (named for English Anatomist Thomas Willis, who described it in 1664), surgery is tricky. Into the circle, like highways converging into a cloverleaf, the four ascending arteries pour the brain's blood supply, and from the circle branch off the principal feeder lines from which oxygen is extracted for the brain's ceaseless activity. Located inside the skull about the eye-and-ear level, the Circle of Willis is in too dangerous a place for surgeons to cut into its vessels. Yet the different segments of the circle's perimeter are subject...
