    Círculos de cultura e plantas medicinais: percepções de discentes e docentes sobre fitoterapia na Educação Profissional e Tecnológica
    (INSTITUTO FEDERAL DE ALAGOAS - Ifal, 2025-10-28) Santos, Pablo Rodrigo Moura; Lima, André Suêldo Tavares de; Santos, Jakeline Maria dos
    This study sought to understand, through the systematization of a culture circle, the perceptions of students and teachers of a Technical Nursing Course on medicinal plants and the government policies that use these vegetables in public health. This is an experience report, with a data collection carried out through observation. It was found that knowledge about medicinal plants was inherited in the family context; that those surveyed expressed knowledge of a good diversity of therapeutic species and; that few knew the public policies in question. It is understood that the research was relevant, both to bring popular and scientific knowledge closer together, and to highlight the importance of working on these policies in Nursing Course classes

    Inclusão tecnológica de estudantes com necessidades específicas: um relato de experiência em Espaços Maker do Instituto Federal de Alagoas
    (Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2023) Albuquerque, Cassiano Henrique de; Cavalcante, Patrícia Smith; Ferreira, Líllian Franciele Silva; Pereira, Renata Imaculada Soares; Almeida, Flávia Bartira Pedro da Silva
    This article aims to present the experience report on the planning and implementation of two courses (3D Modeling and Printing and Internet of Things) carried out through an inclusive maker project at the Federal Institute of Alagoas (Ifal), to accommodate students with specific needs. The courses were held at Ifal campuses in the cities of Arapiraca and São Miguel dos Campos in Alagoas, in January and March 2023, with a duration of 20 hours each. The initial results highlight the importance of adapting offerings for this audience, as well as the positive impact of these initiatives on the lives of visually and hearing impaired students.

    Influence of Polycarboxylic Ether Superplasticizer (PCE) on the Absorption Capacity of Sulfate- and Potassium-Based Superabsorbent Polymers (SAPs) for Use in Cement-Based Materials
    (2025-05-20) Maciel, Priscila de Souza; Silva, Maria Luiza Malta da Rocha; Bezerra, Augusto Cesar da Silva; Tenório Filho, José Roberto; Gomes, Paulo César Correia
    Superabsorbent polymers (SAPs) have a highly hydrophilic network, absorbing and retaining large amounts of water or aqueous solutions, making them useful for internal curing in cement-based materials. Absorption is influenced by the SAPs characteristics, the medium, and the testing method. In many studies reporting on the use of SAPs in cementitious materials, their absorption capacity is usually tested via demineralized water or artificial cement filtrate solution (which does not always include the presence of superplasticizers). PCE-based superplasticizers are among the most used chemical admixtures for concrete, especially when fluid/self-compacting mixtures are produced, and their chemical composition can strongly influence the absorption capacity of different types of SAPs (due to the presence of polymer chains with sulfonic groups (-SO3H)). This study focused on determining the absorption capacity of three commercial SAPs for use as internal curing agents. The absorption capacity was investigated via the tea-bag method, filtration test, and slump-flow test with cement pastes. The chemical composition significantly influenced absorption: SAP A (with higher K2O content) presented lower absorption with the superplasticizer, whereas SAPs B and C (higher SO3) were less impacted because the high polarity favored absorption. The results indicate that the addition of superplasticizers can negatively affect the performance of SAPs in specific applications in civil construction. This impact highlights the need for further investigations into the absorption and desorption mechanisms of SAPs in the presence of these additives, with the aim of optimizing dosing strategies and improving field application methodologies.
