A experiência barroca e a identidade local na Semana Santa de Campanha, Minas Gerais

Este trabalho analisa a formação de uma sensibilidade barroca em Minas Gerais a partir da orientação participativa e altamente emotiva das festas coloniais, cujo legado se mantem presente nas festas religiosas de muitas antigas cidades mineradoras do estado. Enfocando as celebrações da Semana Santa na cidade sul-mineira de Campanha, o texto mostra como este evento anual era organizado pela Irmandade do Santíssimo Sacramento, passando então às mãos de uma comissão local após a extinção da irmandade. Se até meados do século XIX, havia músicos semi-profissionais contratados para tocar e cantar nas celebrações, a música foi assumida progressivamente por grupos de amadores. Assim, a festa passou a ser entendida como uma produção local e a cada ano a população renova o seu orgulho campanhense, ao contemplar sua capacidade de produzir um evento tão ‘maravilhoso’.

This paper analyses the formation of a baroque sensibility in the State of Minas Gerais (Brazil) that derives from the participatory and highly emotive orientation of the colonial festivals, the legacy of which is still present in many former mining towns in the region. By focusing upon the Holy Week celebrations in Campanha, a small town in southern Minas Gerais, the text shows how this annual event was organized by the Confraternity of the Holy Sacrament, but was then transferred to a local committee after the confraternity was made extinct. If up to the mid 19th century there were semi-professional musicians to perform for the celebrations, responsibility for the music was slowly taken over by amateur groups. In this way the festival came to be understood as a local affair, and each year the population renews its pride in itself for its capacity to stage such a ‘marvelous’ event.

Es teatro vuestra oración: Santa Teresa’s performed confession in Juan Mayorga’s La lengua en pedazos

Juan Mayorga’s La Lengua en Pedazos (2010) strikes at the heart of the compositional circumstances of St Teresa's Libro de la Vida– staging, and arguably heightening the origins of her rhetorical strategies, the sense of awareness of readership and potential censure we encounter within the Libro de la Vida. His inquisitor refuses to be complicit in the tacit agreement that the word spoken in the theatrical space can conjure new realities –insistent on underscoring the textual origin of the visions painfully and partially offered up for his and our scrutiny. I will suggest that the persistent undertow towards a meta-commentary on the unmaking and remaking of the autobiographical text creates an unresolved tension between Teresa’s eloquent ability to take the spectator to a place beyond language, and our awareness that we are in the presence of a consummate performer, the textual source for the script itself produced with a supreme awareness of audience scrutiny. The play reflects ongoing lines of inquiry in our evolving understanding of the cultural production of Teresa and other holy women of the Early Modern period.

Extraction of cesium ions from aqueous solutions using calix[4]arene-bis(tert-octylbenzo-crown-6) in ionic liquids

Solvent extraction of cesium ions from aqueous solution to hydrophobic ionic liquids without the introduction of an organophilic anion in the aqueous phase was demonstrated using calix[4]arene-bis(tert-octylbenzo-crown-6) (BOBCalixC6) as an extractant. The selectivity of this extraction process toward cesium ions and the use of a sacrificial cation exchanger (NaBPh4) to control loss of imidazolium cation to the aqueous solutions by ion exchange have been investigated.

Quantification of all-ceramic crown margin surface profile from try-in to 1-week post-cementation

To use profilometry to assess the margin surface profile of all-ceramic crowns (ACC’s) at try-in and 1-week after cementation with dual-cured resin (DC, RelyX ARC, 3 M ESPE, St. Paul, MN, USA), self-adhesive dual-cured resin (SADC, RelyX Unicem, 3 M ESPE), light-cured resin (LC, RelyX Veneer, 3 M ESPE) or chemically cured resin-modified glass ionomer (RMGI, RelyX Luting Plus, 3 M ESPE) luting cement. Methods: Forty, sound, extracted, human, premolar teeth underwent a standardised preparation for ACC’s. IPS Empress (Ivoclar-Vivadent, Liechtenstein) crowns of standard dimensions were fabricated and 10 luted with each cement and stored in water for 7 days. Three groups of serial profiles were taken, the first of the tooth preparation, the second of the crown margins at try-in and lastly of the crown margins after cementation and 7 days water storage. Results: There were no significant differences in the crown margin surface profile between the four cement groups at try-in. The change in crown margin position between try-in and post-cementation was significantly greater for DC than for LC and RMGI. SADC was not significantly different to the other cements. There were no significant differences in the crown margin extensions between the four cement groups, however most of the IPS Empress ACC’s in this study were underextended but this was not statistically significant. Conclusions: IPS Empress ACC’s seated more fully with LC and RMGI than with DC cement
