...vent above your head in the ceiling begins to hum. This means the executioner has turned on the fan to suck up the smell of burning flesh. There is little time left. On your right you can see the waisthigh, one-way mirror in the wall. Behind the mirror is the executioner, standing before a gray marble control panel with gauges, switches and a foot-long lever of wood and metal at hip level...
...panel's most distressing discovery was a stray steel chip, perhaps a burr from a screw, in an exhaust vent of the suit's oxygen supply system. If the fragment had been in the pure oxygen area and caused a spark (by hitting a wall, for example), it might have touched off a catastrophic flash fire, killing Lenoir and possibly ripping a fatal hole in Columbia's sides as well. In fact, a suit did catch fire in a test at Houston two years ago; fortunately no one was wearing it. It was so incinerated that...
...bacterial decomposition of organic matter produce some of the damaging acidic sulfur and nitrogen compounds. But most experts believe that the current problem is directly traceable to the burning of fossil fuels by power plants, factories and smelting operations and, to a lesser extent, auto emissions. When tall smokestacks vent their fumes, sulfur dioxide, nitrogen oxides and traces of such toxic metals as mercury and cadmium mix with water vapor in the atmosphere. Chemical reactions follow that form dilute solutions of nitric and sulfuric acids-acid rain...

Last December, Smith gave public vent to his changed views with the publication of Storm-Kompas, a booklet in which 24 prominent Afrikaner clergy and writers attacked apartheid on religious and moral grounds.

Last month Smith was prominent among the 123 N.G. Church clergy who issued a fierce, indeed historic, protest against the regime...
Although a nylon net pre vents a fall to the ground, the dangers are considerable if something goes wrong. Both brothers could land on their necks or heads, causing injury, or possibly even death. As the catcher, Juan also runs the risk of a shoulder dislocation. To pre vent such accidents, the brothers have made their bodies into pieces of interlocking machinery: they play soccer together for agility, lift weights for strength and box together to heighten their sensitivity to each other's movements. Miguel is small, 5 ft. 7 in., and slim, as fliers tend...
