A New Slide Rule

A New Mixing Rule for Mixtures of Hard Spheres

A mixing rule for the mixtures of hard-spheres is presented which can be reduced to the standard van der Waals mixing rule at low densities. The effectiveness of the mixing rule for the size and energy parameters of lennard-Jones fluid are examined by combining them with an equation of state to calculate thermodynamic properties. The results of calculation are compared with the molecular dy...

New slide test for infectious mononucleosis.

The rapid and simple slide test for infectious mononucleosis designed by Hoff and Bauer (1965) is designed and compared with a modified sheep-cell slide screening test (Maloney and Malzone, 1949) and the differentenial absorption technique (Davidson, 1937). The claim of Hoff and Bauer that their test is more ;specific' is substantiated. Brief clinical histories illustrate the argument.

New implementation of a non-associated flow rule in rate-independent plasticity

One of the new research fields in plasticity is related to choosing a proper non-associated flow rule (NAFR), instead of the associated one (AFR), to predict the experimental results more accurately. The idea of the current research is derived from combining von Mises and Tresca criteria in the places of yield and plastic potential surfaces in rate-independent plasticity.  This idea is implemen...

The Healthy Food Slide Rule (HFSR): a nutrition education tool for children.

A slide rule for time conversion for bromsulphalein (BSP) retention studies.

THE Bromsulphaleimm (BSP) test of Rosenthal ammd White (1) has undergone several modifications (2) imi the 40 years following its introduction. Like most drugs, BSP is removed from blood plasma at a rate which is proportional to its concentratiomi, that is, a first-order reactiomi (3). As would be expected for a first-order reaction, a graph of In (BSP) or log (BSP) vs. time results iii a strai...
