We have performed a Monte Carlo simulation study of a system of ellipsoidal particles with donor± acceptor sites modelling complementary hydrogen-bonding groups in real molecules. We have considered elongated Gay± Berne particles with terminal interaction sites allowing particles to associate and form dimers. The changes in the phase transitions and in the molecular organization and the interpl...

We have investigated the stacking of model bowlic mesogens, and the nematic and columnar liquid crystal phases they form upon cooling– down from an isotropic liquid. Starting from an attractive–repulsive interaction obtained generalising the Gay–Berne pair potential to bowlic shapes, we have performed extensive off–lattice Monte Carlo NPT computer simulations of samples of various sizes: N = 10...

THE coronary vasculature is influenced by physical (arterial pressure, extravascular compression, hematocrit), neural, and chemical factors, and although there is considerable interplay among these various factors, the predominant one is chemical. Furthermore, the chemical factors of greatest importance are those that take origin from the cardiac parenchyma! tissue and serve as a link between m...

Enzyme immunoassays were developed for the detection of Breda virus antibody and antigen. Cattle sera collected in the United Kingdom were found to have a high prevalence of antibody (55%) to Breda virus when examined in a competitive enzyme-linked immunosorbent assay. A low prevalence of antibody was found in pigs (2.2%), and no antibody was found in sheep or goat sera. No antibody to either B...

We present a simple molecular level model based on Gay-Berne monomers linked by finitely extendable nonlinear elastic potential bonds for describing main chain polymerization in liquid crystals. We apply the model to study the influence that the order of the medium has on the characteristics of the chains obtained. We find that the chains prepared from the nematic are actually straighter than t...
