Reis do Congo no Brasil, séculos XVIII e XIX

This article aims to explain the existence of Black kingdoms, later known as "congadas", in almost all Brazilian regions that received African slaves from the sixteenth to the nineteenth centuries. The approach places Portugal, Central Africa, and Brazil as component parts of a single economic, social and cultural system, woven around the Atlantic. Concerned primarily with the formation of identities, the analysis focuses on the cultural sphere and on power relations.Esse artigo busca explicar a presença de reinados negros, depois chamados de congadas, em quase todas as regiões do Brasil que receberam escravos africanos, do século XVI ao XIX. O enfoque adotado abarca Portugal, África Central e Brasil como partes integrantes de um mesmo sistema econômico, social e cultural, tecido em torno do Atlântico. A esfera da cultura e as relações de poder são os centros focais da análise, que se preocupa acima de tudo com a formação de identidades

Saint Anthony from araucaria-pine tree-knots: material expression of a mixed devotion

Existentes no antigo Congo, na África Centro-ocidental, imagens de Santo Antônio foram lá confeccionadas e utilizadas de formas particulares. Quando relacionadas a esse contexto, pequenas imagens de Santo Antônio feitas no Vale do Rio Paraíba paulista ganham novos sentidos, só perceptíveis quando são consideradas as culturas de origem dos escravizados para lá levados. Este artigo atualiza a análise já feita pela autora em artigo anterior, trazendo novas informações acerca das circularidades atlânticas que uniram o sudeste paulista à África Centro-ocidental.Present in the ancient Congo, in West-Central Africa, images of Saint Anthony were made there and used in specific ways. When related to this context, small images of Saint Anthony made in the River Paraíba valley, at São Paulo, acquire new meanings, only perceptible when we consider the cultures of origin of the enslaved who arrived there. This article updates the analysis already done by the author in another article, bringing new information about the Atlantic circularities that connected the Southeast of São Paulo to West-Central Africa

Measurement of the cosmic ray spectrum above 4×10184{\times}10^{18} eV using inclined events detected with the Pierre Auger Observatory

A measurement of the cosmic-ray spectrum for energies exceeding $4{\times}10^{18}$ eV is presented, which is based on the analysis of showers with zenith angles greater than $60^{\circ}$ detected with the Pierre Auger Observatory between 1 January 2004 and 31 December 2013. The measured spectrum confirms a flux suppression at the highest energies. Above $5.3{\times}10^{18}$ eV, the "ankle", the flux can be described by a power law $E^{-\gamma}$ with index $\gamma=2.70 \pm 0.02 \,\text{(stat)} \pm 0.1\,\text{(sys)}$ followed by a smooth suppression region. For the energy ($E_\text{s}$) at which the spectral flux has fallen to one-half of its extrapolated value in the absence of suppression, we find $E_\text{s}=(5.12\pm0.25\,\text{(stat)}^{+1.0}_{-1.2}\,\text{(sys)}){\times}10^{19}$ eV.Comment: Replaced with published version.
