Delta ratio, or " delta-delta ", is a formula that can be used to assess elevated anion gap metabolic acidosis and to evaluate whether a mixed acid–base disorder ( metabolic acidosis) is present. The anion gap (AG) without potassium is calculated first and if a metabolic acidosis is present, results in either a high anion gap metabolic ...

Δ−. (ddd), which respectively carry an electric charge of +2 e, +1 e, 0 e, and −1 e . The Δ baryons have a mass of about 1 232 MeV/c2; their third component of isospin and they are required to have an intrinsic spin of 3 2 or higher (half-integer units). Ordinary nucleons (symbol N, meaning either a proton or neutron ), by contrast, have ...
