1. A hardened, splined bushing, sometimes freely rotating, slightly larger than the outer diameter of a core barrel and mounted directly above the core barrel back head. Also known as ferrule; fluted coupling.

1. Any powdered or liquid additive used as an agent in soil stabilization.

2. Any substance that tends to maintain the physical and chemical properties of a material.

The stabilizer of a point x in a Riemann surface X, relative to a group G of conformal mappings of X onto itself, is the subgroup G_x of G consisting of elements g such that g(x ) = x. Also known as stability subgroup.
