Modeling the isotropic/smectic-C tilted lamellar liquid crystalline transition

Extensions of a previously presented Landau-de Gennes type liquid crystalline phase transition model for the direct isotropic/smectic-A (lamellar) a phase transition to the direct isotropic/smectic-C (tilted lamellar) transition are studied. Two different proposed extensions to the model are studied both in the context of ideal ordering (point volume) and full three-dimensional uniaxial scalar/...

On the efficient execution of bounded Jaro-Winkler distances

Over the last years, time-efficient approaches for the discovery of links between knowledge bases have been regarded as a key requirement towards implementing the idea of a Data Web. Thus, efficient and effective measures for comparing the labels of resources are central to facilitate the discovery of links between datasets on the Web of Data as well as their integration and fusion. We present ...

Wound Hormones of Plants H. the Isolation of a Crystalline Active Substance

abalone sperm appears simply to be concerned in the penetration part of the fertilization process. Summary.-A lytic agent having the property of dissolving the egg membrane has been extracted from sperm of the giant keyhole limpet (Megathura crenulata). The lysin is non-dialyzable and readily inactivated by heat. It precipitates upon saturation of the extract with ammonium sulphate. The precipi...

A Crystalline Pressor Substance (angiotonin) Resulting from the Reaction between Renin and Renin-activator

1. Renin reacts with renin-activator to form a strong pressor substance which is heat-stable, water- and alcohol-soluble, fluorescent, acid-stable, and alkali-labile. It is a reducing substance and is destroyed by strong oxidizing substances. It forms crystalline salts with oxalic and picric acids. The color reaction for arginine is the only one found to be strongly positive. It is suggested th...
