Witryna154 P. Pisarski, G. Haran¶ v^(k;k0) = [vi +vaf(k)f(k0)]^¿3; (1) where vi, va represent the isotropic and anisotropic amplitudes of the potential, respectively. We rewrite vi and va in terms of an overall impurity potential v and a potential partition parameter fi (0 • fi • 1) which divides v into isotropic and anisotropic channels: vi = fiv, va = (1¡fi)v.The … Witryna19 lut 2014 · An initial assessment is performed on the synthetic pathway to identify real or potential impurities that may be ‘reactive’; i.e. can react with DNA. Similarly, an assessment is performed on real or potential degradants (those that may be reasonably expected to form during long-term storage conditions) in drug substance or drug product.
