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.
Boiling chips, also known as boiling stones, boileezers or anti-bumping granules, are small, irregularly shaped stones added to liquids to make them boil more smoothly. They provide nucleation sites so the liquid boils easily without becoming superheated. Without boiling chips, a liquid heated in a smooth container can become superheated and release vapor suddenly, sometimes violently. This sudden bubble of gas can cause the solution and reagents to be thrown out of the container, possibly causing severe burns, ruining an experiment, or simply making a mess.
