Marek's disease virus DNA appears to be wound around a central structure connecting the two inner poles of the capsid. Based on electron micrographs of Marek's disease virions, a diagram of spatial configuration of virus DNA is presented. This diagram may explain the pleomorphic character of the herpesvirus core observed with the electron microscope.

Marek and Truszczy nski studied the representability issue for default logic. They proved that an arbitrary default theory can be represented by a weak seminormal default theory provided the language L has been extended by new atoms. We will prove in this paper that their construction preserves also rational and skeptical rational extensions.
