Moreover, the ?D value of C16 fatty acid in an algal specie named A . E . unicocca at 25 �C was determined using the empirical equation y = 0.890x-91.730 where x is the ?D of water at harvest.

A quantitative description of the nuclear force relies on partially empirical equations that model the internucleon potential energies, or potentials . ( Generally, forces within a system of particles can be more simply modeled by describing the system's potential energy; the negative gradient of a quantum mechanical properties of the nucleon system.
