Dickinson formula

Stone performed a histological study of the depth of penetration of various phenol formulas the Gordon-Baker formula at 48.5% phenol, the Verner-Dickinson formula at 67% and liquid phenol at 88%. The results, in keeping with the principles set out above, show that Baker s formula penetrates twice as deeply as Verner s and four times as deeply as liquid phenol at 88%. Although phenol is absorbed rapidly by skin tissue, only a part of it will gradually reach the innermost regions, as the skin proteins flocculate almost immediately, and this creates a physical catchment area for the phenol as well as a natural dam that stops it penetrating the deeper layers too quickly. 

The response of the interface to an external perturbation is analyzed using the interfacial stress tensor S. For a pairwise-additive interaction, S is given by the Kirkwood formula (Doi and Edwards, 1986 Wijmans and Dickinson, 1999a)... 

In effect, however, the differences in plasma and urine taurine concentration between the infants fed formulas md those fed humcui milk are greater in term infants than they are in preterm infants. The small concentrations of taurine in plasma of infants fed artificial formulas has been documented by others but not commented on (Dickinson et al., 1970).
