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.
Roche limit, Hill sphere and radius of the planet [edit]. Consider a planet with a density of and a radius of, orbiting a star with a mass of M in a distant of R, Let's place the planet on its Roche limit: Hill sphere of the planet here is around L1(or L2): , Hill sphere ..........(4). see Hill sphere, or Roche lobe.
