In this contribution, we model the "long-time" behaviour of the desorption from an LDPE sheet, using non-Markovian random walks. It is shown that the mass of penetrant in the final stage of desorption decays as t-m, where rn is proportional to the exponent of the probability distribution q/(t)-t-O+Β°
A generalized Nee-ZwanzΓ―g equation is proposed to describe both low and high frequency dielectric relaxation. It is shown that the inertial effect is closely related to the non-markovΓ―an character of the dΓ―ferential equation governing the time evolution of the dipole-dipole autocorrelation function.
