Sérgio Buarque de Holanda na USP

The main purpose of the article is to describe and to analyse Sérgio Buarque de Holanda's trajectory in Universidade de São Paulo (USP). At USP, he could dedicate himself entirely in what he liked to do: to research. There, Sérgio Buarque de Holanda formed a researchers' group and he changed the teaching routes in History course, which formed only Elementary and High School teachers. He idealized and founded the Instituto de Estudos Brasileiros (Brazilian Studies Intitute), a multi-disciplinary institution responsible for important researches included the theme Brasil. In this Institute (IEB), he formed a ample archive and a important library. In 1969, the 13-years-job at USP finished itself in a careworm process, when he asked for his retirement in sympathy with other retired professors compulsorily by AI-5.

Universal or provincial? early reception of brian friel´s philadelphia, here I come!

This article, part of a larger research work that resulted in a Professorship Thesis, presents a survey and evaluation of the early reception of one of Brian Friel’s first plays: Philadelphia, Here I Come! (1964). The article also explores the question of emigration from Ireland in the 1950s and 1960s, considering British legislation on the matter, and comments on the eventual influence such issue, among other factors, may have had on criticism about the performance of the play at the time.

Color tunability in green, red and infra-red upconversion emission in Tm3+/Yb3+/Ho3+ co-doped CeO2 with potential application for improvement of efficiency in solar cells

The preparation of Tm3+/Yb3+/Ho3+ co-doped CeO2 prepared by the precipitation method using ammonium hydroxide as a precursor is presented. By X-ray diffraction the materials show the phase-type of fluorite structure and the crystallite sizes were calculated by the Scherrer's equation. No other phase was observed evincing that the rare earth ions were inserted into the fluorite phase as substitutional or interstitial dopants. The microstrain calculated by the Williamson-Hall method do not show significant changes in their values, indicating that the inclusion of rare earths does not causes structural changes in the CeO2 used as a host matrix. All material showed intense upconversion emission at red and green region under excitation with diode laser at 980 nm. The color of emission changes from green to red with increasing excitation power pump. The materials showed suitable photoluminescent properties for applications as a laser source, solar cells, and great emitter at 800 nm. (C) 2014 Elsevier B.V. All rights reserved.
