Race & Diet. Dr. Jarvis' explanation of the near-magical powers of vinegar is that it is unusually rich in potassium, and he rates this as the element most important in stimulating growth. In cold fact, even apple-cider vinegar (in the amounts he prescribes) is decidedly poor in potassium. And although this element is essential to life, its relationship to growth is unknown...
Avco is working on two MHD generators. One of them will burn coal in a stream of compressed, preheated air. While passing through the flame, the air gets hotter, expands and rushes out of the furnace at high speed. A small amount of potassium chloride fed into it increases its ionization and makes it a better electrical conductor. Then the stream shoots into a hollow cone made of a heat-resisting, nonconducting material (see diagram). Electrical coils outside the cone create a strong magnetic field. As the gas speeds through, a powerful current of electricity flows across...
...high enough to support the thermonuclear reactions that keep stars hot. But they need not be cold. "The heat to support life," said Shapley, "would come from their interiors, and they would not be dependent on a sun as we are. In such bodies, radioactive thorium or potassium might provide a source of energy...
...colleagues had tested a chemical that flushes out strontium selectively and spares the body's calcium. Used so far only in rats (no human victims of acute radiostrontium poisoning are known), the chemical is a tasteless yellow dye, the rhodizonate salt of either sodium or potassium. Lindenbaum and his colleagues dosed their rats with the mildly radioactive strontium 85, which, for the purpose of the test, served as well as its deadlier big brother, strontium 90. Then the rats got the rhodizonate in moderate-to-huge doses every which way: intravenously, by injection into the peritoneal cavity, by stomach...
...narrow, underdeveloped pulmonary artery. Tapes are prepared for shutting off the main vessels which carry the blood to Debbie's heart and lungs. The plastic tubes are passed through a chamber of the heart to the large veins. Debbie's heart is opened." Then an injection of potassium citrate stopped the heart for 15 minutes; in throat-parching closeups, the hole inside Debbie's still, flaccid heart, too big for safe stitching, was repaired with a plastic patch made from stuff similar to kitchen sponges. Two weeks later Debbie went home-with every likelihood of a normal...
