Estimation of Small Quantities of Uranium in Thorium

Estimation of Small Quantities of Uranium in Thorium

Date: 1946
Creator: Weissman, S. I. & Duffield, R. B.
Description: Abstract: "Estimation of the intensity of the uranyl fluorescence furnishes a method for the determination of quantities of uranium as low as one-half microgram of uranium in one-half illilitor of glassy phosphoric acid. The test has been used to detect directly three parts of uranium in one million parts of thorium" (p. 1).

The Lagrangian Multiplier Method of Finding Upper and Lower Limits to Critical Stresses of Clamped Plates

The Lagrangian Multiplier Method of Finding Upper and Lower Limits to Critical Stresses of Clamped Plates

Date: January 1, 1946
Creator: Hu, Pai C. & Budiansky, Bernard
Description: The theory of Lagrangian multipliers is applied to the problem of finding both upper and lower limits to the true compressive buckling stress of a clamped rectangular plate. The upper and lower limits thus bracket the truss, which cannot be exactly found by the differential-equation approach. The procedure for obtaining the upper limit, which is believed to be new, presents certain advantages over the classical Raleigh-Rite method of finding upper limits. The theory of the lower-limit procedure has been given by Trefftz but, in the present application, the method differs from that of Trefftz in a way that makes it inherently more quickly convergent. It is expected that in other buckling problems and in some vibration problems problems the Lagrangian multiplier method finding upper and lower limits may be advantageously applied to the calculation of buckling stresses and natural frequencies.
