...secret is an afterburner developed by the Blu-Surf Division of Hayes-Albion Co. of Jackson, Mich., and installed on a stack of the S.D. Warren Co., a paper mill whose emissions have long irritated Muskegon residents. Paper mills smell because they emit sulfide and methyl-mercaptan gases. Instead of venting those gases into the air, the destinking system sends them into a special furnace fed by pressurized air and natural gas. The fumes are then forced through a flame that burns at 1350° F., which is the oxidation point of the sulfides and mercaptans. The resultant oxides...
Allow me to correct a few of the more blatant errors. First methyl alcohol (not ethyl alcohol) has been found toward the galactic center. The group responsible for this discovery includes Carl A. Gottlieb and A. E. Lilley of Harvard and H. E. Radford of the Smithsonian Astrophysical Observatory. Dr. Radford supervised the all-important measurements of the laboratory frequencies. The formic acid discovery was made by a group headed by B. Zuckerman of the University of Maryland and including Gottlieb and Radford...
...brief period after DDT was first put to use In 1945, the pasture mosquito seemed under control in California. But within seven years, the insects had become so resistant to the new chemical that researchers had to develop another organic compound, ethyl parathion. That failed in 1961-as did methyl parathion in 1963, and fenthion in 1968. Today, California has no chemical able to kill the pasture mosquito in safe dosages...
Agency officials now realize that mercury changes its potency in water; through a complex chemical reaction, the relatively harmless inorganic form is transformed into deadly methyl mercury. Minute amounts are picked up by microorganisms, which are then eaten by small fish, which in turn are eaten by large predatory fish like pike and pickerel. When humans eat these fish, they can receive dosages of methyl mercury massive enough to cause blindness, brain damage, and even death...
Since late 1962, Charnley has used the polyethylene socket, which is also cemented in place with methyl methacrylate. In an intensive follow-up of his first 500 cases, Charnley has found the cement holding perfectly. The polyethylene, originally 10 mm. thick, wears away at the rate of about 1 mm. in five years. "No discomfort should be noticed until at least 50% has worn away," he says, "and if that happens, we can always replace the socket...
