## Abstract Three variational statements for the slow time‐independent flow of a Navier‐Poisson fluid are derived. All of these statements are suitable as the bases of finite elements. The first statement is applied successfully to several flow situations.
Samples of SrCOI, irradiated in a nuclear reactor, have been used to determine the ratio between the activation cross sections of the two proceases NSr(n, ~)ssSr (65 d) and uSr(n, ~)ssSr. Methods of absolute ~ and counting have been used for this purpose. The ratio between the two isotopic cross sec
