  Background: The study of deep-inelastic reactions of nuclei provide a vehicle
to investigate nuclear transport phenomena for a full range of equilibration
dynamics. These inquires provide us the ingredients to model such phenomena and
help answer important questions about the nuclear Equation of State (EOS) and
its evolution as a function of neutron-to-proton $(N/Z)$ ratio. Purpose: The
motivation is to examine the real-time dynamics of nuclear transport phenomena
and its dependence on $(N/Z)$ asymmetry from a microscopic point of view to
avoid any pre-conceived assumptions about the involved processes. Method:
Time-dependent Hartree-Fock (TDHF) method in full 3D is employed to calculate
deep-inelastic reactions of $^{78}$Kr+$^{208}$Pb and $^{92}$Kr+$^{208}$Pb
systems at 8.5~MeV$/A$. The impact parameter and energy-loss dependence of
relevant observables are calculated. In addition, density constrained TDHF
method is used to compute excitation energies of the primary fragments. The
statistical deexcitation code GEMINI is utilized to examine the final reaction
products. Results: The kinetic energy loss and sticking times as a function of
impact parameter are calculated. Final properties of the fragments (charge,
mass, scattering angle, kinetic energy) are computed. Conclusions: We find a
smooth dependence of the energy loss, $E_\mathrm{loss}$, on the impact
parameter for both systems. On the other hand the transfer properties for low
$E_\mathrm{loss}$ values are very different for the two systems but become
similar in the higher $E_\mathrm{loss}$ regime. The mean life time of the
charge equilibration process, obtained from the final $(N-Z)/A$ value of the
fragments, is shown to be $\sim 0.5$~zs. This value is slightly larger (but of
the same order) than the value obtained from reactions at Fermi energies.
