Surface Tension and Ferment Action

Studies in Ferment Action

1. A single intravenous injection into dogs of a sufficient number of freshly washed typhoid bacteria produces the symptoms and pathology that characterize anaphylaxis in these animals. 2. These effects are not produced by the coagulable protein-free filtrate from a fresh emulsion, while a similar filtrate from an emulsion digested with leucoprotease is very potent, the toxic portion of the bac...

Studies on Ferment Action

1. Erythrocytes have definite lipoidal constituents and lipoidal combinations peculiar to the species. 2. Certain lipoids and lipoidal combinations act as specific antigens. 3. The increase in serum lipase which occurs upon immunization of animals to foreign red cells is, at least in part, specific. 4. This specific lipase plays, no doubt, an important part in specific serum hemolyses.

MODELING SURFACE TENSION AND WALL ADHESION IN MOLD FILLING PROCESS

Abstract: In this study an algorithm for mold-filling simulation with consideration of surface tension has been developed based on a SOLA VOF scheme. As the governing equations, the Navier-Stokes equations for incompressible and laminar flows were used. We proposed a way of considering surface tension in mold-filling simulation. The proposed scheme for surface tension was based on the conti...

Density and Temperature Dependencies of Liquid Surface Tension

In this paper the density and temperature dependencies of surface tension are investigated. Using the Lennard-Jones (12,6), as an effective pair interaction potential, a linear expression is derived for isotherms of g /r2  versus r2 for some normal and ChloroFluoroCarbons (CFCs)</...
