When a normal person becomes unconscious from breathing too much nitrogen, faints from low blood pressure, or simply goes to sleep, the fast small waves on the chart are replaced by large slow waves, one to five a second...
...alloys were subjected to the pressure tests. They were commercial duraluminum, three aluminum alloys, a lead-calcium alloy, and an iron nitrogen alloy. Each alloy was submitted to the proper temperature, for the time necessary to insure complete solution of the precipitant. It was then quenched in water. The hardness was immediately taken. The alloy was permitted to age at room temperature, one series under high pressures, and a second series at ordinary pressures. After aging for definite time periods, hardness tests were again made...
...effects of pressure on the age-hardening period were most marked in the lead alloy; the aluminum alloys came next; while the iron nitrogen alloy was not affected even when pressure was run up to 20,000 atmospheres...
...least, Dr. Wert notes that this relative compressibility might be thought to explain the nature of his results although "one would hardly anticipate from their comparative values that the lead alloy would be many times as sensitive to pressure effects as are the aluminum alloys or that the iron nitrogen alloy would show,--if, indeed, it shows anything,--a sensitivity so small as to escape detection by the usual Rockwell hardness tester...
Last week the Curie-Joliots proposed for elements made artificially radioactive such names as radio-nitrogen, radio-aluminum, radio-silicon. They foresaw the use in cancer therapy of packets of artificial radio-elements, which, because they disintegrate as the radiation dwindles, would not have to be withdrawn from the body after treatment as radium seeds must be. They told of experiments presaging the production of a radio-phosphorus which would emit neutrons (emitted by no natural radioactive substance). And they spoke of work indicating the existence of the neutrino, an ultimate particle lacking electrical charge like the neutron, but small...
