A comparison of methods of determining the amount of radium in rocks and minerals
(University of Missouri--Columbia, 1914)
This paper is chiefly the outcome of a study of the radioactivity of the rock at different depths from the surface obtained during the drilling of the University deep well number 2. The first method described by J. Joly ...
A comparison of some methods of estimating radium
(University of Missouri--Columbia, 1914)
The quantitative determination of the small amounts of radium present in the atmosphere, spring waters, minerals and rocks involves two steps: (1) The quantitative separation of the radium emanation in a known weight of ...
An investigation of the drying properties of the lead, manganese, and cobalt soaps of tung oil
(University of Missouri--Columbia, 1914)
Lead, manganese, and cobalt linoleates are well known "driers" of linseed oil, and the drying properties of oils boiled with litharge and manganese dioxide are thought due, at least in part, to the formation of linoleates ...
