(Bivalvia, Ostreidae) na baía de São José - Maranhão Abstact: The responses of organisms as an environmental monitoring tool have been used by organisms sensitive to changes that occur in the environment. Among the organisms used as biomonitors, oysters stand out, which accumulate large amounts of contaminants in their tissues. In this sense, this research aimed to determine the physical-chemical parameters of seawater at three points in São José Bay, Maranhão - Brazil, perform biometry of oysters of the genus Crassostrea, evaluate the anthropic impact through the quantification of nitrites (NO2) and identify oyster species through molecular analysis. For this, oysters of the genus Crassostrea were collected in the dry season in October 2022 and the rainy season in March 2023 at three points in São José Bay, point S1 (cultivation - Raposa), S2 (extractivism - Paço do Lumiar) and S3 ( urban area- São José de Ribamar). During the time of each collection (low tide), the physical-chemical parameters of the water were recorded at all sampling points and compared with CONAMA Resolution No. 357/2005, 2 ml of seawater was also collected at the three sampling points for NO2 quantification. The nitrite present in the oysters' supernatant was analyzed indirectly through the Griess reaction, which quantifies nitrites. For molecular analysis, DNA extraction techniques using the saline protocol and the Polymerase Chain Reaction were used. Analyzes of the physical-chemical parameters of seawater demonstrated that pH and temperature remained within established limits, except during the rainy season in the extractive area. The concentration of dissolved oxygen remained low at points S2 and S3. In the biometric analysis, it is possible to observe that oysters from extractivism are smaller in all dimensions, especially in the rainy season. The result of nitrite quantification in the oyster supernatant revealed significantly higher concentrations in the extraction area (dry period 0.41 ± 0.7 mg/L and rainy period 0.28 ± 0.11 mg/L), showing that this area is the most impacted. Regarding molecular identification, it was possible to observe a pattern of bands that correspond to Crassostrea gasar and Crassostrea rhizophorae. Therefore, the results found indicate that the quantification of nitrites is an innovative, simple, effective and lowcost tool that can be used in environmental monitoring in addition to the physicalchemical parameters of water and biometric analysis.

This monograph investigates how African history was worked at the Centro de Ensino Integrado João Francisco Lisboa school in 2019, based on an experience as a scholarship holder of the Institutional Program for Teaching Initiation Scholarships (PIBID), which included observations of classes and activities of fellows with students. In addition to observations at school, this work highlights the analysis of the most used resource in the classroom, the textbook Conexões com a História (2016) and the Programa Nacional do Livro Didático (PNLD) and, finally, they present Suggestions were made for didactic proposals for working on African themes in the third year of high school, using cinema and literature.

Maria Alice Coutinho, belonging to the municipal public network of São Luís – MA. The objective of the research is to analyze the possibilities of access, permanence and learning of students with intellectual disabilities, when supported by Specialized Educational Assistance (AEE), and how much this Special Education service can contribute to students' literate and literacy processes intellectually disabled. The theoretical assumptions that underlie this study, regarding Inclusive Education, Intellectual Disability, Specialized Educational Assistance and Literate and Literacy for Students with Intellectual Disabilities, are outlined based on the contributions of Vygotsky (2022), Hehir (2022), Bourdieu ( 2020), Zerbato; Mendes (2018), Diamond (2016), Noronha (2016), Garcia (2015), Barnes (2013), Poulin, Figueiredo; Gomes (2013) and Figueiredo (2012), among others. In addition to official normative documents that support and regulate the Education of people with intellectual disabilities. Regarding the methodology, it is characterized by using a qualitative approach, of an applied nature, regarding explanatory objectives, and the methodological procedures are outlined as bibliographic, documentary and case study, using the instruments, on-site observation, interview scripts and questionnaires, the results of which will serve as the basis for the production of an orientation guide that contributes to the pedagogical praxis teachers about literate and literacy of students with intellectual disabilities, in response to the problem and research objectives Thu, 07 Nov 2024 00:00:00 GMT https://repositorio.uema.br/jspui/handle/123456789/5984 2024-11-07T00:00:00Z https://repositorio.uema.br/jspui/handle/123456789/5982 Título: O uso do geogebra no ensino de geometria espacial: uma sequência didática investigativa para o ensino médio Abstact: This research aims to develop an Investigative Didactic Sequence (SDI) that integrates GeoGebra and the exponential function, in order to understand the characteristics of the sequence’s development using this software as a tool for teaching the proposed mathematical content. To support this investigation, an analysis was conducted on the use of Information and Communication Technologies (ICTs) in the classroom, the features of GeoGebra, and the possibilities of employing it as a didactic resource in Mathematics education. A research survey was also carried out by examining scientific communications published in the Proceedings of the National Meeting on Mathematics Education (ENEM) from the 10th to the 14th editions, focusing on studies involving the use of GeoGebra in the teaching and learning of functions, particularly the exponential function. The research methodology adopted was qualitative, bibliographic, and exploratory, seeking to understand how the SDI can be articulated through the use of the software in relation to the exponential function. The study highlights the relevance of adopting new methodologies supported by technological tools in Mathematics classes. The results indicate the importance of planning and organizing sequenced and interconnected lessons; promoting active student participation; encouraging problem solving; developing critical thinking; fostering collaboration in the classroom; and stimulating investigation of the mathematical concept under study Wed, 01 Jan 2025 00:00:00 GMT https://repositorio.uema.br/jspui/handle/123456789/5982 2025-01-01T00:00:00Z
