Figure 4.
Model-based data showing how % absorption (a) and total absorbed amount (b) are modified by the experimental duration for selected values of Nderm. The dimensionless time number, Ntime, is the ratio of experimental duration to the lag time for diffusion. For a given compound, increasing experimental duration increases the applied load amount that defines a specific Nderm, in accordance with Eq. (2). Symbols represent calculated values; the lines are a guide to the eye.
