  • <p>Africas Diabolical Entrapment exposes Sub-Saharan Africa as a region that is wantonly bruised it its trap between two major religions in the continent namely Christianity and Traditional Animism. It compares religious beliefs in Africa with historical religious developments in other continents of the world to identify where Black Africa is getting it wrong. While advancing the central message that the belief in Witchcraft, Demigods, Spirits of the dead, the Ancestors and Jesus Christ is not peculiar to Africa it also emphasizes that the pervasiveness of these beliefs in todays Africa poses a serious challenge to the intellectual growth of the society in general. Its conclusive projections and recommendations are definitely a subject of interest to stakeholders in the process of starting a long overdue debate in a continent that is waiting to find its place among progressive nations.</p>画面が切り替わりますので、しばらくお待ち下さい。 ※ご購入は、楽天kobo商品ページからお願いし...

  • <p>This thesis describes the application of state-of-the-art high-energy X-ray studies to the astronomical quest for understanding obscured active galactic nuclei (AGN). These AGN are supermassive black holes growing by accretion of matter located in the nuclei of galaxies. The material that feeds these black holes also obscures them from view, rendering them challenging to study. It is possible to study them by effectively 'X-raying' galactic nuclei to peer through these obscuring veils.</p> <p>Beginning with the proof-of-concept application of novel X-ray Monte Carlo codes to the Nuclear Spectroscopic Telescope ARray (NuSTAR) spectrum of a known heavily obscured AGN, the thesis establishes the relevant parameters that characterise the AGN spectrum and central black hole growth rate. Next the largest sample of known heavily obscured AGN is compiled, finding the strength of a prominent iron spectral feature to weaken with AGN power. This is puzzling, and suggeststhat there may...
