...developed uranium mines on the Colorado Plateau (where it is building 783 miles of new roads), has found good prospects in the Black Hills of South Dakota. ¶ In Joliet, Ill., the Blockson Chemical Co. will soon begin full-scale production of uranium from a new source, phosphoric acid. ¶ Barely started on its new $3.5 billion expansion program, the AEC already employs about 3% of the total construction force of the nation...
...average farmer can't afford such luxury." Furthermore, said Krajewski, it wasn't just Secaucus and it wasn't just pigs. The industrial areas near the Pulaski Skyway, he said, smell like embalming fluid: "Linden has assorted smells from paint and oil... There are chemical and acid smells, and Kopper's coke with its terrible smoke. Out in Manville, there is the asbestos smell . . . And in Newark, you should smell the markets in the morning. No one complains about them...
...learn more about the mysteries of the human body is by analyzing the structure of proteins, of which the vital parts of all living creatures are made. The job is complicated by the fact that the typical protein molecule is built up of hundreds or thousands of amino-acid-units which link together in complex ways. They form long chains, they branch, they tangle, they join together in rings. Even to identify the amino acids in a simple protein is a difficult task for the most skillful chemist. To figure how they are arranged in the protein molecule has baffled...
Chemist Sanger worked with crystalline insulin, a comparatively simple protein. First he broke the large molecules by oxidation into two fragments, one containing 21 amino-acid building blocks, the other 30. Then by other methods (e.g., hydrolysis), he broke the two parts down until he had fragments that contained only a few amino acids each. These were compounds familiar to biochemists. Sanger identified them by paper chromatography,† and the first and easiest part of his job was done...
There were no patterns of gains & losses by industries. Too many abnormal factors -the excess-profits tax, war orders, price and production controls-were affecting different companies in too many different ways. Furthermore, with most industries once more in a hotly competitive market, companies again faced the acid test of efficiency, and some passed it far better than others...
