Composition analysis of high-Tc superconducting thin films by quantitative x-ray fluorescence

A method is presented for determining the composition of thin films containing the elements Bi, Sr, Br, Cu, and Ca. Quantitative x-ray fluorescence (XRF) consisting of radioactive sources (secondary foil excitor 241Am-Mo source and 55Pe source), a Si(Li) detector, and a multichannel analyzer were employed. The XRF system was calibrated by using sol gel thin films of known element composition and also by sputtered thin films analyzed by the conventional Rutherford Back Scattering (RBS). The XRF system has been used to assist and optimize the sputter target composition required to produce high-Tc BiSrCaCuO films with the desired metal composition.

Comitum princeps tu mihi eris: Rape and the Distribution of Auctoritas in Ovid's Fasti

In Ovid’s Fasti, the rape narratives of Callisto, Lara, Flora, and Carna contain the common themes of the distribution of auctoritas and/or the subversion of auctoritas. While all four characters are victims of rape, Callisto loses auctoritas as a result of her rape by Jupiter, whereas Flora and Carna gain auctoritas from their rapes by Zephyrus and Janus respectively. Since Ovid associated Augustus with Jupiter on more than one occasion in the poem, it appears that readers were meant to see a parallel between Jupiter’s dealings with auctoritas in these narratives and Augustus’ exercise of his auctoritas over Rome. Zephyrus’ and Janus’ bestowal of auctoritas upon their victims was intended to be a foil for Jupiter’s denial of auctoritas to Callisto and strict regulation of his own auctoritas, which Lara’s narrative exemplifies, in order for Ovid to criticize the overwhelming nature of Augustus’ auctoritas, as well as specific Augustan policies.
