The trigonometric form of the energy density gradient [[partial derivative].sub.w] = [partial derivative]/ [partial derivative] ([[omega].sub.[direct sum]][R.sub.[direct sum]] sin [delta]/c), where [delta] denotes declination (Figure 1), for the integration of declination from the inbound to outbound asymptote has been derived earlier [16].

An additional quantum potential is included in density gradient (DG) model for calculating the driving force of electrons and holes [10, 11].
In order to generate isolated lengths species from the as-received fractions an ultracentrifuge technique is used on the nanotubes which have been suspended in a density gradient fluid.
There are variations in the separation media used but dextran-based sedimentation is typically used in conjunction with a Ficoll-Hypaque density gradient centrifugation step.
However, because NL119 was a nonencapsulated strain originally recovered from a single colony and well-isolated by repeated passages in vitro, and no encapsulated subpopulation was ever retrieved in vitro by the selection using Percoll density gradient centrifugation, the most plausible hypothesis would be that the capsule-recovered S.
