...Trace of Water. The first aspirin was made by Germany's Bayer company, and its U.S. descendant (a division of Sterling Drug Inc.) today charges six to ten times as much as no-name brands. To justify the difference, Bayer contrasts U.S.P.*minimum standards with its own. Before tableting, says U.S.P., the basic chemical must be in tabular or needlelike crystals or crystalline powder; to produce a dependable dissolving rate, Bayer requires a special flake shape and needle shape (slender, tapered at both ends). U.S.P. permits .5% moisture and weight loss on drying; Bayer will tolerate none. U.S.P. allows...
...several obstacles to its construction. For one thing, the Law requires that the Temple be administered by Cohens (priests), who are the descendants of Moses' brother Aaron. Yet so many nonpriestly Jews have assumed the name Cohen that rabbinical experts would face a legal nightmare in trying to trace authentic genealogies. For another, the Torah specifies that Temple ritual include daily animal sacrifices-a concept alien to the humane sensitivities of most modern Jews. An even greater obstacle is that the Temple must be constructed on its original site; this could only be done by demolishing Islam...
Through Interpol, police the world over can trace a Bombay jewel thief with a dozen aliases and passports, study the latest research on police use of helicopters, learn how Lebanon is persuading farmers to grow sunflowers instead of hashish-or call on the FBI's monumental files of 184 million fingerprints. By holding annual conventions on a different continent each year, Interpol unites the world's fuzz-Tokyo detectives, Canadian mounties, U.S. narcotics agents-for mutual education in everything from electronics to odonto-grams (tooth identification). In addition, Interpol organizes regular seminars on scientific crime detection, sends forgery...
...averaging of these patterns by scientists at Block Associates in Cambridge, Mass., produced two of the clearest spectrograms ever obtained of Venus at high altitude. Although the spectrograms conclusively proved that there were no ice crystals in the Venusian atmosphere, they did reveal what appeared to be a significant trace of water vapor. But Kuiper and his associates were not deceived...
...atmosphere still above them, the airborne astronomers had also taken about 1,000 interferograms of the moon, which was close to Venus in the sky during the flight. Although the moon is known to be dry, the lunar spectrograms produced by the Block computers also showed evidence of a trace of water vapor. The vapor, the scientists knew, had been detected not on the moon but in the earth's atmosphere. Thus, by eliminating the same proportion of terrestrial vapor from the Venus spectrograms, they were able to determine the true amount of Venusian water vapor-approximately one-half...
