Simulated pharmacokinetic data from patients on efavirenz are used. The FourierĄ¯s Equation is used to infer on transfer of movement between solution particles. The work investigates diffusion using FickĄ¯s analogy, but in a different variable space. Two important movement fluxes of a solution particle are derived an absorbing one identified as conductivity and a dispersing one identified as diffusivity. The FourierĄ¯s Equation can be used to describe the process of gain/loss of movement in formation of a solution particle in an individual. %K Partial Differential Equations %K Conductivity Flux %K Diffusivity Flux %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=71971
