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.
Back to top. Inhalants are a chemically diverse group of psychoactive substances composed of organic solvents and volatile substances commonly found in more than 1,000 common household products.This includes a variety of gases, glues, and aerosols. The substances enter the brain so rapidly that the intensity resembles the effects produced by intravenous injection of other psychoactive drugs. 2  Inhalants can be sniffed directly from an open container. 3  They can be huffed from a rag soaked in the substance and held to the face.
