“…Nevertheless, all social classes have access to screens and the children spend most of the time indoors, using near work electronics during their spare time [39]. This might explain the apparent growing prevalence of myopia over the last decade among Brazilian school children and the higher risk of 6.5% for additional hours of near work activities reported by this study [40,41].…”

Purpose: Myopia has been considered a public health issue by the World Health Organization since 2015.The growing incidence of myopia worldwide, called the myopia epidemic, and its potential blinding complications in adulthood like cataract, glaucoma, retinal detachment and maculopathy, have been extensively published and discussed in peer review papers. Nonetheless, little information about Latin America is available. This study aims to detect the prevalence of myopia in southern Brazil, the biggest country of South America. Methods: A prospective cross sectional study recruited 330 public school children between 2019 and 2021, aged 5 to 20 years old. All children underwent a comprehensive eye examination and detailed lifestyle questionnaire. The Pearson correlation coefficient, Kruskal Wallys and the Chi-Square Test were used to assess simple correlations and associations between myopia and medical conditions, use of medications, ophthalmic history and family history of ocular conditions, besides demographics and lifestyle focused on screen time/day. Associations between the results of the ophthalmologic evaluation and all factors included in the questionnaire were analyzed using the Generalized Estimating Equation model (GEE). The prevalence of hyperopia and astigmatism were also assessed. Results: Total prevalence of myopia was 17.4% (CI 13.8 – 21.7%). Low myopia (-0.50D to -5.75D) comprised 15.2% (CI 11.9 – 19.3%) and high myopia (-6,00D or worse) was 2.1% (CI 1.1 – 4.1%). Relative risk of myopia for females was 1.6 (CI 1.00 – 2.57%) and each additional hour of screen time increased a child’s chance of having myopia by 6.5%. The prevalence of hyperopia was 7,7% (CI 5.4 -10.9%) and of astigmatism, either myopic or hyperopic, was 25.6% (CI 21.4 – 30.2%). Conclusions: Brazil has always been considered a hyperopic country. These are the highest reported prevalences of myopia under cycloplegia and the first paper to present myopia as a more prevalent refractive error than hyperopia among Brazilian school children to date.

“…O setor terciário, no qual os supermercados fazem parte, é o responsável por expressiva porcentagem do Produto Interno Bruto -PIB do país. Em 2020, por exemplo, o ramo de supermercados no Brasil faturou cerca de 7,5% do PIB do Brasil, chegando a um valor de aproximadamente 554 bilhões de reais (AGÊNCIA BRASIL, 2022). Portanto, os supermercados são de suma importância para a economia e para a sociedade.…”

Este texto tem como objetivo apresentar uma caracterização do ramo supermercadista na cidade de Ituiutaba, Minas Gerais. Vale lembrar que os supermercados desempenham papel importante no âmbito da vida econômica e cotidiana da população e, dessa maneira, consideramos importante compreender as características relativas ao ramo supermercadista e a sua relação com as cidades, considerando elementos atinentes às lógicas e estratégias das empresas e as práticas cotidianas da população. Sendo assim, para esta análise, foram realizadas pesquisas bibliográficas sobre os temas ligados ao ramo supermercadista, além de pesquisa de campo e levantamentos de informações sobre as empresas, tendo em vista as principais características dos estabelecimentos, como o porte, a origem do capital e a sua localização no espaço intraurbano. Os resultados demonstram características importantes como a chegada recente das empresas de capital externo e a introdução de novos formatos de lojas e lógicas de localização, além de lançar questões para a continuidade e aprofundamento das investigações sobre o tema na cidade.

“…Nowadays, six centuries later, occupying the second largest producer and consumer of ethanol in the world, only behind the USA (UNEM, 2021), Brazil is responsible for producing about 31.6 billion liters of ethanol in 2019, according to the website of Agency of Brazil and Conab (National Supply Company of Brazil) (Agência Brasil, 2019). Hydrated ethanol sold at gas stations reaches 18.9 billion liters and anhydrous ethanol, used in the mixture with gasoline sold at gas stations, reaches 10.5 billion liters.…”

The use of biological agents for the large-scale production of biofuels has stood out as successful processes for the advancement of science in the world. The growing exploitation of biomass in the agricultural sector and the emergence of new energy sources generated from food industry waste have become attractive and viable due to the potential and variety of possibilities for using different sources of biomass. The present review was carried out through careful bibliographical research in the literature and in scientific journals for the current discussion of concepts, production methodologies and challenges for the energy sector considering second-generation ethanol (2G ethanol). Several 2G ethanol production methodologies have been implemented as a potential low-cost alternative energy production that follows the principles of Green Chemistry.
