Nekrasov Cossacks
Nekrasov Cossacks, Nekrasovite Cossacks, Nekrasovites, Nekrasovtsy (Некрасовцы, Некрасовские казаки, Казаки-некрасовцы.) descend from those Don Cossacks who, after the defeat of the Bulavin Rebellion of 1707-1708, fled to the Kuban in September 1708, headed by Ignat Nekrasov, hence their name.

Specific gravity
Specific gravity is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume.

Sulfosalt minerals
Sulfosalt minerals are those complex sulfide minerals with the general formula: AmBnSp; where A represents a metal such as copper, lead, silver, iron, and rarely mercury, zinc, vanadium; B usually represents semi-metal such as arsenic, antimony, bismuth, and rarely germanium, or metals like tin and rarely vanadium; and S is sulfur or rarely selenium or/and tellurium.
