Surface tension-like forces determine bacterial shapes: Streptococcus faecium.
The same tendency that causes soap bubbles to achieve a minimum surface area for the volume enclosed seems to account for many of the features of growth and division of bacteria, including both bacilli and cocci. It is only necessary to assume that growth takes place in zones and that only in these zones does the tension caused by hydrostatic pressure create the strain that forces the cell to i...
متن کاملHigh-order Techniques for Calculating Surface Tension Forces
In this paper we develop further the “height fraction” technique for computing curvature directly from volume fractions. In particular we, (1) develop a systematic approach for calculating curvature from volume fractions which is accurate to any order, and (2) we test the second-order “height fraction” technique on the following two-phase problems: (1) the break-up of a cylindrical column of li...

متن کاملA molecular theory of surface tension in nematic liquid crystals
The surface tension at the free surface of a nematic liquid crystal is computed using the Fowler-Kirkwood-Buff approximation to the interface, and a mean field approximation to the molecular pair distribution function. It is found for a Van der Waals interaction between molecules that : a) the molecules always prefer an orientation in the plane of the surface; b) there is a gap at the nematic-i...
متن کاملMolecular simulation of the surface tension of real fluids
Molecular models of real fluids are validated by comparing the vapor-liquid surface tension from molecular dynamics (MD) simulation to correlations of experimental data. The considered molecular models consist of up to 28 interaction sites, including Lennard-Jones sites, point charges, dipoles and quadrupoles. They represent 38 real fluids, such as ethylene oxide, sulfur dioxide, phosgene, benz...
