Ethnic Jew is a term generally used to describe a person of Jewish parentage and background who does not necessarily actively practice Judaism, but still identifies with Judaism or other Jews culturally or fraternally, or both.

Branching (polymer chemistry) chain termination and branching. The branching index measures the effect of long-chain branches on the size of a macromolecule in solution. It is defined as g = b</sub»/l</sub», where s is the mean square radius of gyration of the branched macromolecule in a given solvent, and s is the mean square radius of gyration of an otherwise identical linear macromolecule in the same solvent at the same temperature. A value greater than 1 indicates an increased radius of gyration due to branching. Branching (polymer chemistry) In polymer chemistry, branching occurs by the replacement of a substituent, e.g., a hydrogen atom,
