Abstract Treating specific tissues without affecting other regions is a difficult task. It desirable to target the particular tissue where chemical has its biological effect. To study this phenomenon computationally, in work we numerically mathematical model which written as nonlinear system composed by three parabolic partial differential equations. The variables involved are concentration of ...

in this study a simple and general chemical association theory is introduced. the concept of infinite equilibrium model is re-examined and true mole fractions of associated species are calculated. the theory is applied to derive the distribution function of associated species. as a severe test the application of presented theory to the van der waals mixture model is introduced in order to perfo...
