It's a myth that the definition of a normal bowel movement is having 1 movement each day because that is not true for everyone. There is no rule for frequency of bowel movements, but the general range is from 3 times a day to 3 times a week.
We investigate the dependence of the stickiness parameters $t_{ij}=1/(12\tau _{ij})$ -- where the $\tau_{ij}$ are the conventional Baxter parameters -- on the solute diameters $\sigma_{i}$ and $\sigma_{j}$ in multicomponent sticky hard sphere (SHS) models for fluid mixtures of mesoscopic neutral particles.
A sphere of incompressible liquid, being in the weightless state (as any cosmic object), is a kind of condensed matter. Forced vibrations of two plates in incompressible fluid are investigated in [7]. We consider the flow of two- dimensional incompressible viscous fluid along a circular horizontal pipe.
