What is a Core? Certain types of auto parts can be recycled or, more specifically, remanufactured for future sale. These parts have a core price that is used as a form of deposit on the portion of the part that can be remanufactured and that is designed to encourage return of the old part. The core, simply put, is your old part. Returning cores can save you money on replacement parts.
A dilatant (also termed shear thickening) material is one in which viscosity increases with the rate of shear strain. Such a shear thickening fluid, also known by the initialism STF, is an example of a non-Newtonian fluid. This behaviour is usually not observed in pure materials, but can occur in suspensions.
Inhalants are substances that produce chemical vapors that, when inhaled, result in mind-altering effects. The term inhalant is used because these substances are rarely, if ever, abused by any other means. These substances are common household, industrial, or medical products. But most people do not think of them as drugs, because they are not meant to be used in that way.
