Mariazinha em África, de Fernanda de Castro: representações coloniais

Este trabalho reconstitui o percurso do romance Mariazinha em África de Fernanda de Castro, desde a primeira edição de 1925 até à décima edição de 1973, dando particular atenção às representações coloniais na primeira edição e na edição revista de 1940, já no quadro do Estado Novo. O tratamento do espaço exótico e da cultura popular guineense, bem como a imagem do negro e das relações entre raças nas duas edições, no plano textual e, mais lateralmente, no plano iconográfico, merecem especial enfoqueThe present dissertation follows the novel Mariazinha em África, by Fernanda de Castro, from it´s first edition in 1925 until it´s tenth edition in 1973, with particular attention to colonial representations in the first edition and the revised edition of 1940, within the framework of the Estado Novo. The treatment of the exotic setting and Guinea popular culture, as well as the image of black people and the relationship between the two races in the textual plain and, more laterally, in the iconographic plain, deserve a special focusMestrado em Línguas, Literaturas e Cultura

Enzymatic vitreolysis for the treatment of tractional diabetic macular edema

© The Author(s), 2019. Article reuse guidelines: sagepub.com/journalspermissionsBackground: A new approach to address focal vitreomacular adhesion in patients with diabetic macular edema may control and stabilize diabetic macular edema with fewer antivascular endothelial growth factor injections. Objectives: The aim of this study was to demonstrate that diabetic macular edema can be improved by inducing the release of a vitreomacular adhesion, with less than 2500μm, with enzymatic vitreolysis. Methods: From a retrospective analysis of clinical records from patients with diabetic retinopathy, patients with diabetic macular edema and vitreomacular adhesion <2500μm were selected for a single-arm prospective study. The primary endpoint was to control diabetic macular edema with fewer anti-vascular endothelial growth factor injections after an observed vitreomacular adhesion release. A statistical subanalysis was performed for the following two groups: the group with vitreomacular adhesion release (group 1) and the group without vitreomacular adhesion release (group 2). Results: A total of 23 eyes from 19 patients were included. A reduction of the median number of injections was achieved in group 1 (p=0.006). Adverse events were mild and transitory. Conclusion: Release of vitreomacular adhesion <2500μm through enzymatic vitreolysis contributed to the control and stabilization of diabetic macular edema with fewer anti-vascular endothelial growth factor injections, reducing the burden and the risks related to these invasive and frequently chronic treatments.info:eu-repo/semantics/publishedVersio

Locating the Youngest HII Regions in M82 with 7 mm Continuum Maps

We present 7mm Very Large Array continuum images of the starburst galaxy M82. On arcsecond scales, two-thirds of the 7mm continuum consists of free-free emission from HII regions. In the subarcsecond resolution map, we identify 14 compact sources, including 9 bright HII regions with N_Lyc > 10^51 sec^-1. Four of the HII regions have rising spectra, implying emission measures > 10^8 cm^-6 pc. Except for one compact source with peculiar features, all other compact radio sources are found in dust lanes and do not have optical or near-infrared continuum counterparts. Four regions of extended, high brightness (EM > 10^7 cm-6 pc) radio emission are found in our high resolution map, including some as large as ~2", or 30 pc, representing either associations of small HII regions, or sheetlike structures of denser gas. The good correlation between 7 mm emission and Spitzer IRAC 8 micron continuum-removed PAH feature suggests that PAH emission may track the recently formed OB stars. We find an excellent correlation between molecular gas and star formation, particularly dense gas traced by HCN, down to the ~ 45 pc scale in M82. We also find star formation efficiencies (SFEs) of 1-10% on the same scale, based on CO maps. The highest SFE are found in regions with the highest dense gas fractions.Comment: 18 pages, 10 figures.

Variação sazonal das borboletas (Lepidoptera) da mata do Museu de História Natural e Jardim Botânico da UFMG, Belo Horizonte, Minas Gerais, Brasil

As borboletas (Lepdoptera), por serem coloridas e de fácil visualização, são ótimas bandeiras para conservação. Também são boas indicadoras ambientais e úteis no monitoramento de ecossistemas. O objetivo desse estudo foi realizar análise da composição, riqueza e abundância das borboletas do Museu de História Natural e Jardim Botânico (MHNJB) UFMG, relacionando esses parâmetros com a sazonalidade. As coletas foram realizadas bimestralmente durante um ano (entre junho de 2016 e maio de 2017). Cada amostragem foi realizada por dois dias, com o uso de redes entomológicas em cada uma das quatro áreas predeterminadas, num total de 48 horas de esforço amostral. Foram coletadas 571 borboletas de 95 espécies, sendo 40 singletons e 14 doubletons. A abundância e a riqueza não variaram entre os meses (F = 1,227, p = 0,337; F = 1,34, p = 0,378, respectivamente) e nem entre as estações (F = 0,7749, p = 0,388; F = 1,0045, p = 0,327, respectivamente). Já a composição das espécies diferiu entre os meses (p = 0,003) e entre as estações (p = 0,017). A curva de acúmulo de espécies não se estabilizou, indicando que há mais espécies para serem amostradas nas matas (áreas T1, T2, T3 e T4) do Museu
