Etnografias do brau: corpo, masculinidade e raça na reafricanização em Salvador Ethnographies of the brau: body, masculinity and race in the reafricanization of Salvador
No full textNeste artigo, o autor pretende explorar desenvolvimentos do processo conhecido como reafricanização da cultura e da política em Salvador corporificados na cristalização transitória de determinada figura social conhecida como o brau. Essa seria uma inflexão de masculinidade informada pelas tensões raciais e de gênero em Salvador, assim como uma re-apropriação localizada de temas culturais da diáspora africana. Braus foram (são) jovens negros da periferia que re-inventam uma visualidade/corporalidade negra a partir de releituras da 'cultura' soul norte-americana e ao mesmo tempo são estigmatizados pela classe média como violentos, de "mau-gosto" e hiper-sexualizados, ou seja, excessivamente 'negros' e excessivamente 'masculinos', em uma hiperbolização que em certo sentido contradiz com sua estigmatização.In this article the author seeks to explore some developments of the process known as the cultural and political reafricanization of Salvador, through the transitory crystalization of social figure called "brau". This would be an inflexion of masculinity informed by racial and gender tensions in Salvador, as well as a localized appropriation of cultural themes of the African Diaspora. "Braus" were (are) young blacks from poor neighborhoods who re-created a black look/corporality from readings of North-American soul culture, while being stigmatized by the middle class as violents, ugly-looking and hyper-sexed, that is, excessively black and excessively male, a hyperbole which in a way contradicts this stigmatization

Using Self-Organizing Maps for the Behavioral Analysis of Virtualized Network Functions
No full textDetecting anomalous behaviors in a network function virtualization infrastructure is of the utmost importance for network operators. In this paper, we propose a technique, based on Self-Organizing Maps, to address such problem by leveraging on the massive amount of historical system data that is typically available in these infrastructures. Indeed, our method consists of a joint analysis of system-level metrics, provided by the virtualized infrastructure monitoring system and referring to resource consumption patterns of the physical hosts and the virtual machines (or containers) that run on top of them, and application-level metrics, provided by the individual virtualized network functions monitoring subsystems and related to the performance levels of the individual applications. The implementation of our approach has been validated on real data coming from a subset of the Vodafone infrastructure for network function virtualization, where it is currently employed to support the decisions of data center operators. Experimental results show that our technique is capable of identifying specific points in space (i.e., components of the infrastructure) and time of the recent evolution of the monitored infrastructure that are worth to be investigated by human operators in order to keep the system running under expected conditions
Fungos e micotoxinas em grãos de cevada (Hordeum vulgare L.) cervejeira, descontaminação pelo gás ozônio e segurança de cervejas artesanais
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências Agrárias, Programa de Pós-Graduação em Ciência dos Alimentos, Florianópolis, 2015.A cevada (Hordeum vulgare L sp. vulgare) é considerada um dos cereais mais importantes no contexto mundial. Atualmente, uma preocupação latente da indústria cervejeira é o crescimento de fungos filamentosos nos grãos, que acorre devido ao manejo inadequado da matéria prima durante o armazenamento (excesso de umidade), a condensação, o aquecimento, o vazamento de água da chuva e a infestação por insetos. Tendo isso em vista e considerando que a cevada é um dos cereais mais comercializados no mundo, o objetivo desse trabalho foi investigar a presença de fungos toxigênicos e micotoxinas nos grãos, avaliar a qualidade da cerveja artesanal produzida no Sul do Brasil, bem como determinar a eficiência do gás ozônio da destruição dos principais fungos encontrados na cevada. Adicionalmente, as características químicas e microestruturais de 5 cultivares de cevada cervejeira recomendados para cultivo no Brasil foram avaliados. As cervejas artesanais apresentaram contaminação por deoxynivalenol (DON) em aproximadamente 32% das amostras analisadas e contaminação por Fumonisina B1 em 15.08% das amostras. Os grãos de cevada cervejeira utilizados na pesquisa apresentar amimportantes espécies fúngicas (Fusarium, Alternaria, Rhysopus e Penicilllum),sendo Fusarium o gênero mais predominante. No que diz respeito a contaminação por DON, a variedade BRS Brau apresentou maior contaminação, representando 50% das amostras desse cultivar. As fumonisinas foram encontradas, contudo, em poucas amostras e baixos níveis. No estudo realizado com O3 como agente descontaminante, a espécie mais suscetível ao gás foi F. poae, seguida pelo F. gramineraum. É necessário mencionar que a germinação dos grãos após os tratamentos com o O3 não foi afetada. Finalmente, no estudo de análise química e microestrutural da cevada cervejeira, o cultivar BRS Brau apresentou características de melhor qualidade para a cevada em comparação com os outros, destacando, elevado teor de amido, com mais presença de grânulos tipo-A e baixas quantidades de proteína.Abstract : Barley (Hordeum vulgare L sp. vulgare) is considered one of the most important cereals in the global context. Currently, a latent concern of the brewing industry is the growth of filamentous fungi in grains, due to the improper manipulation of raw material during storage (excess of moisture), condensation, heating and infestation by insects. Regarding it and considering that barley is one of the most cereals comercialize din the world, the aim of this study was to investigate the presence of toxigenic fungi and mycotoxins in grains, evaluate the quality of craft beer produced in southern Brazil, and to determine the ozone gas efficiency of the destruction of some fungi found in barley. In addition, chemical and microstructural of 5 barley cultivars recommended for cultivation in Brazil were evaluated. The craft beers showed levels of deoxynivalenol (DON) in approximately 32% of the samples, and contamination with Fumonisin B1 in 15.8% of samples. The malting barley grains used in the research presented important fungal species (Fusarium, Alternaria, Rhysopus and Penicilllum) being Fusarium the most predominant genus. Concerning DON, the Brau variety showed more contamination, representing 50% of the samples. Fumonisins have been found, however, in a few samples and low levels. In the study of O3 as decontamination agent, the most susceptible species to the gas was F. poae, followed by F gramineraum. It is necessary to mention that the grain germination after treatment with O3 was not affected. Finally, chemical and microstructural analysis study of the brewing barley genotypes, BRS Brau showed better quality characteristics compared to the others, emphasizing high starch, with more presence of A-type starch granules, and low amounts of protein
Measurement of j / psi production in continuum e+ e- annihilations near s**(1/2) = 10.6-GeV
No full textThe production of J/ψ mesons in continuum e<sup>+</sup>e<sup>-</sup> annihilations has been studied with the BABAR detector at energies near the ϒ(4S) resonance. The mesons are distinguished from J/ψ production in B decays through their center-of-mass momentum and energy. We measure the cross section e<sup>+</sup>e<sup>-</sup>→J/ψX to be 2.52±0.21±0.21 pb. We set a 90% C.L. upper limit on the branching fraction for direct ϒ(4S)→J/ψX decays at 4.7×10<sup>-4</sup>
BOUND-FREE EMISSION FROM XeBr, XeI, AND KrF
No full textJ. J. Ewing and C. A. Brau, Phys. Rev. A12, 129 (1975).Author Institution: Department of Chemistry, NashvilleThe e-beam-excited emission bands of XeBr (2700-2850 {\AA}), XeI (2400-2550 {\AA}), and KrF (2400-2525 {\AA}) display a diffuse structure characteristic of bound-free emission from a near thermal (at ) distribution of Levels to a relatively Hat lower potential curve. The nature of this structure is discussed. Spectral simulations are used to obtain approximate potential curves for the electronic states involved in these transitions
Search for f(J)(2220) in radiative J/psi decays
No full textWe present a search for f(J)(2220) production in radiative J/psi --> gamma f(J)(2220) decays using 460 fb(-1) of data collected with the BABAR detector at the SLAC PEP-II e(+)e(-) collider. The f(J)(2220) is searched for in the decays to K+K- and (KSKS0)-K-0. No evidence of this resonance is observed, and 90% confidence level upper limits on the product of the branching fractions for J/psi --> gamma f(J)(2220) and f(J)(2220) --> K+K-((KSKS0)-K-0) as a function of spin and helicity are set at the level of 10(-5), below the central values reported by the Mark III experiment
