Thesis (M.Sc. (Physics)) --University of Limpopo, 2006 / In this work, we are studying the properties of CaS and CaO structures in both atomistic simulation and Density Functional Theory. Defects formation (vacancies, impurity and interstitial) will be mechanism studied by using atomistic simulation method. In this approach, Mott-Littleton method will be used since it is a good ap- proach of defects studies, and further explanation will be given on how the introduction of defects contribute on the stability of the bulk material. Diffusion of different atoms from one lattice site via interstitial path to vacancy lattice site, and how it segregates through the material, is also part of this study. The surface properties will be studied using both methods mentioned. Surface energies calculations of different surface layers (e.g. CaS (100), CaS (110), CaS (111), CaO (100), CaO (110) and CaO (111)) is the approach we used to determine the most stable surface. In atomistic simulation, we further studied how percentage coverage of atoms contributes on the stability of the surfaces. We further used Density Functional Theory to calculate surface energies of the above-mentioned surfaces. As in atomistic simulation method, we used surface ener- gies to determine the most stable surface. In DFT we used only the most stable surface of both CaS and CaO to study the adsorption of molecules, namely H2O, H2S, HS and S2 on CaO (100) and CaS (100). The most/least-adsorbed molecule on both surfaces is explained in this study.

The cytoskeleton plays an important role in trafficking proteins and other macromolecular moieties throughout the cell. Viruses have been thought to depend heavily on the cytoskeleton for their replication cycles. However, studies, including one in our lab, found that some viruses are not inhibited by anti-microtubule drugs. This study was undertaken to evaluate the replication of viruses from several families in the presence of cytoskeleton-inhibiting drugs and to examine the intracellular localization of the proteins of one of these viruses, Sindbis virus, to test the hypothesis that alternate pathways are used if the cytoskeleton is inhibited. We found that Sindbis virus (Togaviridae, positive-strand RNA), vesicular stomatitis virus (Rhabdoviridae, negative-strand RNA), and Herpes simplex virus 1 (Herpesviridae, DNA virus) were not inhibited by these drugs, contrary to expectation. Differences in the localization of the Sindbis virus were observed, suggesting the existence of alternate pathways for intracellular transport.
