Que tesão! a masculinidade na pornografia gay

Este artigo discute a representação do masculino na pornografia gay, tendo como objeto de estudo o ator Rafael Alencar e sua performance em filmes pornô. Para tal, questiona como a heteronormatividade interfere na constituição de sujeitos masculinos, tidos como desviantes sexuais, representados na pornografia para homens gays. De forma que é possível constatar a falácia desta representação, a qual contribui para a perpetuação de processos excludentes. Os corpos, o desejo, a atração, são delineados por imagens que seduzem através da violência e da marginalização. Essa hipótese é defendida com base em autores e comentadores dos Estudos Queer, como: Miskolci (2007; 2017), Junqueira (2012; 2013), Takara e Teruya (2016). Além disso, como metodologia, opta-se por uma pesquisa qualitativa exploratória com base em fontes bibliográficas e documentais

Grupos de investigação em educação superior: por onde anda a produção do conhecimento científico?

No artigo apresenta-se, a partir de um mapeamento, o perfil dos grupos de pesquisa em educação superior cadastrados no Diretório de Pesquisa do Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) em universidades públicas da região Sul do Brasil. A investigação é bibliográfica e documental, tendo como metodologia de análise a histórico-crítica. As discussões contribuem para identificar os eixos temáticos que caminham à produção do conhecimento científico via pesquisa na educação superior no Brasil, destacando como consequência a efetiva e tão discutida ideia de (re)produtivismo acadêmico em nível mundial e suas repercussões no Brasil

Development of natural and innovative material for application as thermal insulation in buildings

The advent of new technologies related to thermal insulation systems in civil construction helps buildings become more efficient, reducing their consumption of electric energy through air conditioning, and providing thermal comfort to users. The research aims to develop a facade cladding board for buildings, with thermal insulation starting from vacuum, and corn cob. Facade coatings with mortar finish were developed, filling them with developed materials. Three prototypes were executed in masonry of ceramic blocks, with dimensions of 60x60x64,0 cm. The Field Logger 512K (Lite) and PT100 sensors were used for data collection of external temperature and internal temperature of the prototypes. Solar radiation data were collected by the university weather station, model Davis-6450. It is worth noting the average internal temperature reduction in Prototype 2 and 3, compared to 1 (without isolation), which was 2.74 ° C and 8.05 ° C

Unlocking Pre-1850 Instrumental Meteorological Records: A Global Inventory

Instrumental meteorological measurements from periods prior to the start of national weather services are designated “early instrumental data.” They have played an important role in climate research as they allow daily to decadal variability and changes of temperature, pressure, and precipitation, including extremes, to be addressed. Early instrumental data can also help place twenty-first century climatic changes into a historical context such as defining preindustrial climate and its variability. Until recently, the focus was on long, high-quality series, while the large number of shorter series (which together also cover long periods) received little to no attention. The shift in climate and climate impact research from mean climate characteristics toward weather variability and extremes, as well as the success of historical reanalyses that make use of short series, generates a need for locating and exploring further early instrumental measurements. However, information on early instrumental series has never been electronically compiled on a global scale. Here we attempt a worldwide compilation of metadata on early instrumental meteorological records prior to 1850 (1890 for Africa and the Arctic). Our global inventory comprises information on several thousand records, about half of which have not yet been digitized (not even as monthly means), and only approximately 20% of which have made it to global repositories. The inventory will help to prioritize data rescue efforts and can be used to analyze the potential feasibility of historical weather data products. The inventory will be maintained as a living document and is a first, critical, step toward the systematic rescue and reevaluation of these highly valuable early records. Additions to the inventory are welcome

CD44 Expression in Oro-Pharyngeal Carcinoma Tissues and Cell Lines

Expression of CD44, a transmembrane hyaluronan-binding glycoprotein, is variably considered to have prognostic significance for different cancers, including oral squamous cell carcinoma. Although unclear at present, tissue-specific expression of particular isoforms of CD44 might underlie the different outcomes in currently available studies. We mined public transcriptomics databases for gene expression data on CD44, and analyzed normal, immortalized and tumour-derived human cell lines for splice variants of CD44 at both the transcript and protein levels. Bioinformatics readouts, from a total of more than 15,000 analyses, implied an increased CD44 expression in head and neck cancer, including increased expression levels relative to many normal and tumor tissue types. Also, meta-analysis of over 260 cell lines and over 4,000 tissue specimens of diverse origins indicated lower CD44 expression levels in cell lines compared to tissue. With minor exceptions, reverse transcribed polymerase chain reaction identified expression of the four main isoforms of CD44 in normal oral keratinocytes, transformed lines termed DT and HaCaT, and a series of paired primary and metastasis-derived cell lines from oral or pharyngeal carcinomas termed HN4/HN12, HN22/HN8 and HN30/HN31. Immunocytochemistry, Western blotting and flow cytometric assessments all confirmed the isoform expression pattern at the protein level. Overall, bioinformatic processing of large numbers of global gene expression analyses demonstrated elevated CD44 expression in head and neck cancer relative to other cancer types, and that the application of standard cell culture protocols might decrease CD44 expression. Additionally, the results show that the many variant CD44 exons are not fundamentally deregulated in a diverse range of cultured normal and transformed keratinocyte lines
