...pressure. A fraction of a second later, when her aortic valve had closed, the ECG signal made the pump fill the balloon with helium. This forced the blood in the aorta not only up and down, but also back to the roots of the coronary arteries, thus increasing the oxygen supply to the heart muscle. Meanwhile the ventricle relaxed and began to refill with blood. The pump emptied the balloon in time to allow a flow of blood from the next heartbeat...
...idea of using TRIP-processed materials to prevent metal fatigue "pure speculation" at this point, it is not beyond the realm of possibility. Other conceivable uses of TRIP steel: storage tanks to withstand the super-coolness (as much as -450° F.) of liquid helium, hydrogen, nitrogen and oxygen; chemical-processing equipment; roller and ball bearings. TRIP, in the estimate of its discoverers, is capable of being produced commercially at prices competitive with other high-strength steels. It may some day be used in the manufacture of deep-diving descendants of such undersea vessels as the bathyscaphe and the three...
...other. It is 6 ft. long, 4| ft. wide, 21 ft. deep. Sheathed in a Johnson-designed nylon heat shield for re-entry into the earth's atmosphere, the craft is equipped with a swivel-mounted retrorocket, attitude-control jets, a transponder for ground control, a built-in oxygen supply, a parachute and a survival kit. Johnson envisions a typical Apollo spacecraft as carrying three such lifeboats in its service mod ule or equipment section...
...Womb at the Top." To abandon a foundering spacecraft, the astronaut dons extravehicular activity (EVA) gear, seals himself in the lifeboat and vents carbon dioxide and excess oxygen from his EVA suit to power the craft's attitude-control system. Face pressed against the porthole, he aligns his lifeboat with the horizon by firing the attitude-control jets. After sighting a landmark on earth with the reticle marked on the porthole, he aims and fires the retrorocket for 100 seconds, thus braking the lifeboat to a de-orbiting speed of 16,500 m.p.h. Then the retrorocket is jettisoned...
Siegel's discovery poses a fascinating possibility that has long intrigued other scientists. The earth's once ammonia-and methane-rich atmosphere has since been recast through the release of subterranean gases and the evolution of oxygen-producing photosynthetic plants. Siegel believes that the Kakabekia-like organism has survived for "a billion years or more" by living on ammonia from the breakdown of proteins in earth. Citing spectroscopic analyses of Jupiter, which indicate that its atmosphere still contains large amounts of ammonia, Siegel theorizes that space explorers on Jupiter may some day meet living relatives of his discovery...
