...tested at "Suzy," North American's test facility in the Santa Susana Mountains northwest of Los Angeles, it is trucked to Leuhman Ridge in the Mojave Desert. There, the test stand towers 275 ft. above the rocky ground. Tucked in its steel skeleton are tanks for lox (liquid oxygen) and kerosene, while stairs, cables, and many-colored pipes thread their way among the girders. The F-1 looks small in this immense structure, but it does not act small. After a careful countdown, a brilliant spout of flame bursts from its throat, and a sound beyond description rolls across...
Subjected to Stress. Deeply inhaled smoke, the researchers found, irritates the cells that line the tiniest chambers of the lung (alveoli). The walls of the alveoli thicken, lose their elasticity and much of their ability to do their vital job of exchanging carbon dioxide for oxygen. Subjected to sudden stress-such as a cough or sneeze-the alveolar walls rupture; part of the lung becomes useless...
Even while the heart is being asked to overexert, carbon monoxide from cigarette smoke combines with red blood cells and decreases their capacity to carry oxygen. As a result, the hard-working heart muscle is given less fuel to do its job. At the same time, tobacco's nicotine causes a constriction of small arteries in the extremities and speeds up the heart, increasing its need for oxygen and complicating the coronary problem...
...France's Usinor steel company is building Europe's largest steel mill near Dunkirk. This, and modernization of other mills, will give France a capacity of 27 million tons by 1965, of which 25% will be produced in the latest oxygen-type furnaces...
...heart as hard as any factory hand was demonstrated in ingenious research reported by Western Reserve's Dr. Herman K. Hellerstein. Investigators rigged up 39 surgeons with electrodes for continuous electrocardiograph records and a cuff for blood pressure readings, fitted the doctors with masks to monitor their oxygen consumption, and conducted a battery of other tests, both before and after the operations. Though the surgeons may have done nothing more strenuous than cutting and tying small blood vessels, they expended, on the average, as much energy as welders or drill-press operators. At the climax of the operations, their...
