(Universidade do Estado do Amazonas, 2025-09-10) Vieira, Luana Maquiné; Albuquerque, Patrícia Melchionna; http://lattes.cnpq.br/1177407730126204; Fonseca Junior, Edson Queiroz da; Guimarães, Taís Xavier; http://lattes.cnpq.br/2459610112523029; Souza, Érica Simplício; http://lattes.cnpq.br/4333531513081697
The Amazon region is known for having countless assets when it comes to its flora. Among the numerous existing species of plants, many of these are considered advantageous raw materials to produce cosmetics, as these vegetables have in their composition actives with remarkable properties to produce the so-called phytocosmetics. Phytocosmetics are formulations that have natural actives in their constitution from extracts or essential oils that define the biological activity of the product. Rosewood essential oil (Aniba rosaeodora) has molecules in its composition with several effective activities for cosmetic formulations, highlighting its antimicrobial activity. Guarana (Paullinia cupana), on the other hand, stands out for having, in addition to antimicrobial activity, other various therapeutic properties, such as antioxidant activity. In this context, the objective of this study was to develop liquid soap formulations with antimicrobial activity from guarana extract and rosewood essential oil, and to evaluate the preliminary stability of the elaborated formulations. After obtaining the guarana extracts and essential oil, the antimicrobial activity was analyzed by the microplate dilution method. The guarana extract that proved to be the most active was the dichloromethane extract, thus, it was chosen to be used in the formulations of liquid soaps. The essential oil was also active, with the lowest Minimum Inhibitory Concentration (MIC) values. The physicochemical properties analyzed in the formulations were: centrifugation, pH, conductivity, viscosity, foam index and relative density, in addition to color, odor and appearance, before and after the preliminary stability tests (thermal stress and freeze-thaw cycle). After the analyses, it was possible to see that, in relation to organoleptic properties, there was no significant difference ((p<0.05) between the newly prepared formulations and after passing through the preliminary stability tests. The changes occurred in the physicochemical parameters, observed mainly due to the increase in temperature. It was also possible to note that the formulation that contained the standard antimicrobial was influenced by radiation, being more visible in the low foam index formed after the analysis, but still, on average compared to other formulations. Thus, it appears that the dichloromethane extract of guarana and the essential oil of rosewood, for having antimicrobial activity, can be interesting in the development of antiseptic liquid soaps.
Memórias, trajetórias e história social da comunidade Santa Luzia do Marauarú, Parintins - AM
(Universidade do Estado do Amazonas, 2025-09-03) Guimarães, Kynderson Silva; Rocha, João Marinho da; http://lattes.cnpq.br/9074944691414686; Rocha, João Marinho da; http://lattes.cnpq.br/9074944691414686; Oliveira, Roger Kenned Repôlho de Oliveira; http://lattes.cnpq.br/9054323639450690; Gomes, Jessica Dayse Matos; http://lattes.cnpq.br/0544330232957582
This text is one aspect of a research project investigating the formation and institutionalization processes of the Santa Luzia do Marauarú Community, located in the interior of the municipality of Parintins, Amazonas. Because this is an original work, our aim is to contribute, through scientific research within the field of Social History, to the valorization of the memory of this locality, where the stories told by collaborators and guardians of memory permeate the community's growth and become the object of reflection and historical investigation. We applied Oral History (OH) methodology to analyze the narratives and problematize them through discussion. We also sought written and photographic records to produce research based on a detailed survey and analysis of the data obtained, as this work can also guide future research. The use of memories was fundamental to the analysis, and we sought documentary sources, providing further evidence of how the community's institutionalization process occurred. Thus, the oral history methodology used in this research offers us a different perspective on events experienced by residents and former residents, illuminating the path outlined here. Using these methods has made it possible to shed light on aspects of the community that would otherwise be difficult to disclose.
O borralho das feiticeiras: imaginário e representações sobre as mulheres farenses
(Universidade do Estado do Amazonas, 2025-09-03) Campos, Joandreo Batalha; Silva, Júlio Cláudio; http://lattes.cnpq.br/4009362157043989; Silva, Júlio Cláudio; http://lattes.cnpq.br/4009362157043989; Rocha, João Marinho da; http://lattes.cnpq.br/9074944691414686; Oliveira, Roger Kenned Repolho de; http://lattes.cnpq.br/9054323639450690
Our article examines representations of femininity in the municipality of Faro, Pará, based on the works of three authors: "Acauã," by Inglês de Sousa (2005); "Tessituras de um rio: Deslocamentos de ruins e Paisagem," by Heldilene Reale (2019); and "Contos e lendas de Faro," by Francisco Azevedo (2004). By discussing the "images" of femininity presented in these three works, we want to highlight the intersection of these representations with a European imaginary associating women with witchcraft, as occurred in the late medieval period with the "witch hunts," a structure we refer to in this article as the "spell imaginary." Furthermore, we raise the possibility that one of the three authors may be less influenced by this imaginary, allowing him to produce less structured representations. The research is embedded within the New Cultural History framework, focusing on the fields of representations and the imaginary, and is further developed through bibliographical research.
Conhecendo os vestígios arqueológicos amazônicos através da Língua Brasileira de Sinais (Libras)

This article was developed as part of the learning process for a deaf student in the History Bachelor's program at the Amazonas State University's Center for Higher Education in Parintins. The research and textual production contributed to the production of sign terms for the main archaeological remains of the Amazon, delivering a product that can serve as teaching aid from a bilingual perspective (Portuguese and Brazilian Sign Language – LIBRAS) for both deaf and hearing students. This production was important because the sources of material culture, the subject of this research, are highly visual, contributing to the perception of many details, enhancing my learning as a deaf student.
O negro no Amazonas: e a sua invisibilização no livro didático de História do Amazonas
(Universidade do Estado do Amazonas, 2025-09-04) Farias, Sednem Mendes; Silva, Júlio Cláudio da; http://lattes.cnpq.br/4009362157043989; Silva, Júlio Cláudio da; http://lattes.cnpq.br/4009362157043989; Rocha, João Marinho da; http://lattes.cnpq.br/9074944691414686; Oliveira, Roger Kenned Repolho; http://lattes.cnpq.br/9054323639450690
This article aims to present the results obtained through qualitative research and the chosen methodology, bibliographic analysis. The information presented here was obtained as a result of the analysis of the textbook Tópicos História do Amazonas Volume Unico by Grafisa Gráfica e Editora LTDA, authored by Agnaldo Figueiredo, used throughout high school in the respective series (1°, 2° and 3° year) during the time record situated in the years (2021-2023), we chose to carry out the analysis in each of the four chapters that make up the book with the intention of finding references to the black presence in Amazonas. Regarding the general objective of the research, which consists of carrying out an analysis of the historiographical representations present in the textbook regarding the black presence in Amazonas, it was noted that despite there being a reasonable number of academic works referring to the topic, the book of History of Amazonas brings black participation in the historical and social construction of the Amazon people in a simplistic way. Since it reduces such participation to an analysis of the numerical quantity of black people brought to what is today the state of Amazonas, thus ratifying the invisibility of the contribution of black hands in the historical compilation and identity of the Amazonian people.
