Based on the principle of axial active magnetic bearing system with single degree of freedom, the difference between magnetic system vibration mode and the traditional bearing system vibration mode were described. Initial four order natural frequencies and vibration mode were calculated by the module of modal analysis of ANSYS11. Axial displacement and control current influence on natural frequencies...
Expression of two Epstein-Barr virus (EBV) immediate-early gene products, Zta (encoded by the BZLF1 gene) and Rta (encoded by the BRLF1 gene), are required for the switch from latent infection to virus replication. We have analyzed the regions of the BRLF1 gene promoter (Rp) that are required for Rta and Zta transactivation of Rp. Notably, significant synergy between the actions of Rta and Zta on...
Induction of the Epstein–Barr virus lytic cycle in latently infected B cells requires the expression of the immediate-early lytic gene BZLF1. We have previously identified severalcis-elements within the BZLF1 promoter that are required for induction by known inducers of the lytic cycle [E. Flemington and S.H. Speck (1990)J. Virol.64, 1217–1226]. These include four elements termed the ZI domains (ZIA,...
The Epstein-Barr virus (EBV) BZLF1 gene is expressed early upon induction of the viral lytic cycle and its protein product is unique in its ability to disrupt viral latency in some latently infected cell lines. Anti-immunoglobulin (anti-Ig) treatment of the Burkitt's lymphoma cell line Akata, which bears surface IgG, has previously been shown to synchronously induce transcription of the BZLF1 gene...
