Environmental studies focused on understanding the origin of organic matter (OM) have been widely addressed in coastal ecosystems, especially with constant anthropic interference, making them more vulnerable. Tools known as molecular markers have become effective as they indicate the occurrence of a specific source or processes. In this study, the organic compounds Aliphatic Hydrocarbons (AHs), Polycyclic Aromatic Hydrocarbons (PAHs) and Sterols, which are widely used to help understand the origin of sedimentary organic matter (SOM), were analyzed. Doce River Mouth (DRM) was directly impacted by the biggest environmental accident involving iron ore tailings, which released about 60 million m3 of tailings into the Doce River channel with the rupture of the Fundão dam, causing major environmental and social impacts. In order to understand how the arrival of the mud has been influenced the sediments of the DRM two short cores were collected in August 2017 (dry winter period), and samples of surface sediments from 15 stations distributed by the DRM were collected in 4 campaigns (August 2017 and 2018; and February 2018 and 2019) to understand the influence of seasonality on biogeochemical processes involving these organic compounds. Results of environmental parameters such as: %TOC, %TN, C/N and molecular markers widely used to evaluate possible sources of organic matter, such as Aliphatic Hydrocarbons (HAs) as well as the δ13C from specific chains of n-alkanes, PAHs and sterols are discussed. The results found for the cores showed that fine grains predominated, n-alkanes indicated an increase in the contribution of terrestrial OM with depth, PAHs showed moderate pyrolytic contamination, with a predominance of compounds with high molecular weight (HMW). The fecal sterol concentrations showed that the surface sedimentary of the cores had a lower sewage signal than before the mud, that is, a dilution of the sewage by the tailings probably occurred. For surface sediments, the sand fraction predominated, as well as the C/N with indices suggesting autochthonous sources, in the 4 campaigns. The HAs have indices that indicate petrogenic sources, with emphasis on the n-C24 chain with the highest concentration, however there are also other index indicating the contribution of terrestrial vegetation, which may indicate a mixture of sources. PAHs from HMW predominated showing a greater pyrolytic contribution, while sterols show a greater contribution from higher plant sources

Matemática financeira : uma proposta de sequência didática para o ensino médio

Financial Mathematics should be a fundamental field of the mathematics of high school, given the everyday human need to analyze and make decisions regarding the use of money and future planning. Its importance goes far beyond the school environment; it is essential in the personal, professional, and social lives of individuals. However, data show a high level of indebtedness in Brazil, and most people still keep their savings in low-interest accounts, reflecting a lack of financial organization and knowledge about the financial market and investment opportunities. Most likely, many of these individuals, like myself, did not receive financial education, either at home or in school. In this regard, this dissertation presents the development of a Didactic Sequence aimed at teaching financial mathematics in high school, with the objective of connecting the content with students’ everyday lives through a practical and interactive approach. The created Didactic Sequence includes topics such as financial organization, percentages, simple and compound interest, rate conversions, saving methods, payment options, the financial market, investments, and loans, exploring each concept through activities that involve real-life situations. By working through this sequence, it is hoped that students will develop calculation skills, critical thinking, and a better understanding of financial concepts, along with an improved ability to apply these concepts in real-life situations. Thus, this dissertation aims to provide substantial material for mathematics teachers to approach financial mathematics in a way that is both relevant and engaging for students

Avaliação do impacto da saúde bucal na qualidade de vida de uma população rural pomerana
(Universidade Federal do Espírito Santo, 2025-03-31) Maria, Lorrayne Cesario; Miotto, Maria Helena Monteiro de Barros; https://orcid.org/0000-0002-3227-7608; Sanglard, Luciana Faria; Barcellos, Ludmilla Awad
Studies dedicated to assessing the quality of life of the rural population and the community are scarce. Expanding research on Pomeranians is essential in order to contribute to the development of public policies that meet their specific needs. This study assessed the impact of oral health on quality of life, possible associations with sociodemographic variables, demand for dentures, dental status, type of access and reason for using dental services in a rural Pomeranian population. This is a cross-sectional study carried out with 300 descendants of Pomeranians, preferably of direct descent, who live in the district of Melgaço, municipality of Domingos Martins, state of Espírito Santo. Data was collected through face-to-face interviews at home, using the Oral Health Impact Profile - 14 instrument to assess quality of life and a structured questionnaire with the other study variables. The Fischer Exact and Mantel Haenszel tests were used for statistical analysis, and the odds ratio was calculated. The impact of oral health on quality of life was declared by 68 individuals (22.7%), with a higher prevalence in the following dimensions: psychological discomfort (13%), physical pain (12.3%) and psychological disability (12%). This impact was associated with individuals aged 41 or over, who had studied up to 12 years, who were non-white and who used the public health service or had no access to it. The absence of at least one tooth, the demand for dental prostheses and the use of dental services as a matter of urgency were factors that had an impact on the quality of life of 22.7% of these individuals.
