    Análise da percepção de mulheres em situação de vulnerabilidade em relação ao consumo ecossustentável de produtos de higiene menstrual
    (Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2024-01-30) Silva, Mércia Dark Bastos da; Cunha, Mônica Ximenes Carneiro da; http://lattes.cnpq.br/1775024859845111; Marques, Sheyla Karolina Justino; http://lattes.cnpq.br/3917387578549073; Gaia, Rossana Viana; http://lattes.cnpq.br/4018992389689693
    This study focused on assessing the perception of women in situations of social vulnerability in relation to the eco-sustainable consumption of menstrual hygiene items, with special attention to the environmental impacts associated with the improper disposal of these products, as well as their composition and production process. The methodological path comprised four stages: (1) Systematic Literature Review; (2) Case study, incorporating interviews and focus group; (3) Content Analysis; and (4) Production of Technical and Technological Products, including Manuals for the use and production of reusable fabric pads, Didactic Manual of guidelines for a more sustainable and healthy menstrual cycle, Didactic Material of guidelines for a more sustainable and healthy menstrual cycle, and Social Technology – Reusable Fabric Pads. The results show that, for women in vulnerable situations, environmental perception is not one of the main factors influencing the adoption of reusable items. The lack of information, together with the limited availability of these products and economic conditions, emerged as determinants in this transition process. Thus, the need to democratize information is highlighted, promoting the autonomy of menstruating people and facilitating more accurate and ecologically conscious choices. The creation of educational materials, such as manuals and teaching resources, represents a practical contribution to empowering women, enabling informed and conscious choices regarding menstrual hygiene. These resources seek to disseminate information about the benefits of reusable products, encouraging more sustainable and healthy practices.

    (2024-04-12) Oliveira, Samantha Ferreira Mendonça de; Marques, Sheyla Karolina Justino; http://lattes.cnpq.br/3917387578549073; Rapôso, Áurea Luiza Quixabeira Rosa e Silva; http://lattes.cnpq.br/7600867517446003; Peres, Ana Paula da Silva; http://lattes.cnpq.br/9975840346577976
    The generation of waste in the Fiberglass Reinforced Plastics (FRP) industry and in Water Treatment Plants (WTP) is a serious environmental and social problem, due to the lack of areas to dispose of these liabilities, which become secondary raw materials for other industrial processes. In this context, the aim of this research was to analyze the characteristics and properties of GRP particulate (PPRFV) and water treatment plant sludge (LETA) in the production of porous ceramics, in order to obtain a more efficient product in the light of the circular economy. The waste was characterized using X-ray fluorescence (XRF), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), derivative and differential thermogravimetric analysis (TG/DTG/DSC) and scanning electron microscopy (SEM). Experimental traces were used with levels of PPRFV (0%, 4%, 6% and 8%) and LETA (5%, 10%, 15% and 20%), as a partial substitute for clay, in which 10 specimens were molded per composition. The data obtained from the response variables was submitted to analysis of variance (ANOVA) and polynomial regression. PPRFV showed a majority of CaO (47.79%) and SiO2 (36.38%), while LETA showed SiO2 (52.06%) and Al2O3 (29.83%). X-ray diffraction detected the presence of an amorphous halo and the quartz crystalline phase in PPRFV and LETA, in that order. The infrared of the PPRFV allowed functional groups that occur in the chemical structure of epoxy resin to be determined, while the sludge showed absorption bands characteristic of clay minerals. Thermal analysis of the particulate revealed an exothermic event at a temperature of around 450°C and a mass loss of 40.33%. The sludge suffered a total mass loss of 14.83%. SEM micrographs of the particulate revealed the existence of fibrous filaments adhered to the particles with a rough texture, while the sludge showed a chip-like shape, characteristic of materials with an organic and inorganic load. With regard to the technological tests, the experimental mix with 8% PPRFV and 20% LETA emerged as the most promising, showing an increase of 83.84%, 47.36% and 26.67% in the Linear Shrinkage, Water Absorption and Apparent Porosity indices, respectively, compared to the reference mix. The Permeate Flow data confirmed the increase observed in the physical tests, reaching a value of 5,222.27 L/m².h for the experimental mix with the highest percentage of waste. Based on the data obtained, this study proved to be important in the development of a technical product with a view to reintroducing GRP particulates and WTP sludge into the water treatment system at the filtration stage.

    Análise das características físico-químicas do lodo da Estação de Tratamento e Água (ETA) da cidade de Arapiraca - AL com perspectiva de aplicação em tijolos cerâmicos
    (2024-10-12) Santos Neta, Jozelita Maria dos; Marques, Sheyla Karolina Justino; http://lattes.cnpq.br/3917387578549073; Oliveira, Samantha Ferreira Mendonça de; http://lattes.cnpq.br/3505971364422580; Tenório, Taisa Menezes; http://lattes.cnpq.br/3208780979075636
    Water treatment results in the generation of sludge, representing a significant environmental challenge. However, it is observed that this byproduct has properties that make it suitable for use in other production chains, especially in the construction industry. In this context, this work consists of analyzing the physical, chemical, and mineralogical properties of sludge from the Water Treatment Plant (WTP) located in the municipality of Arapiraca-AL, with the aim of characterizing the sludge for its potential application in the production of ceramic bricks, aiming to promote a closed-loop cycle. The methodology adopted in this study is based on the experimental characterization of the raw material through tests for granulometry, liquid limit, plasticity, X-ray fluorescence, and X-ray diffraction, in addition to thermogravimetric analysis. The results indicated that the sludge is classified as fine aggregate, with a predominance of medium and fine particle size distribution. Additionally, the byproduct was characterized as non-plastic. In the chemical analysis of the environmental liability, the presence of fluxing chemical components such as K2O (4,52%), CaO (1,86%), and MgO (0,15%) was identified. These chemical compounds have fluxing characteristics that can reduce the time and temperature of ceramic material sintering when in contact with agents forming a vitreous phase. Furthermore, the most relevant percentages of silica (53,50%) and aluminum (28,74%) were identified in the form of quartz and kaolinite, corroborating the results obtained through X-ray fluorescence. In the thermal analysis, a mass loss of around 42% was recorded up to a temperature of 400°C. Finally, it is important to highlight the potential use of WTP sludge as an alternative raw material in light of the circular economy in the construction sector, which could contribute to mitigating environmental impacts.

    Due to its composition, post-consumer carton packs have great potential to be used as an input in the manufacture of new products. In this context, this research aimed to analyze the performance of partial replacement of fine aggregate by triturated carton packages in the development of a masonry mortar. The methodology was divided into the following steps: elaboration of a systematic literature review; collection, preparation and comminution of carton packages; characterization of raw materials; definition of the reference and experimental compositions; performance of technological tests; and analysis of results. In the fine aggregate, granulometric analysis was performed. The by-product, Triturated Cartons Packages (ECT), was characterized by Chemical Analysis by X-Ray Fluorescence (XRF) and Scanning Electron Microscopy (SEM). The proportion of 1:6 of volume of cement and fine aggregate was adopted as reference and experimental compositions were determined with substitutions of 5%, 10% and 15% of volume of aggregate by ECT, being molded and tested 5 specimens for each composition. The tests of Consistency Index, Compressive Strength, Water Absorption by Immersion and SEM of Fracture Surface were performed. It was carried out the correlation analysis between the average values of the properties and the percentage of ECT replacement. As for the results of the Consistency Index test, the mortars with ECT replacement showed a small reduction, but they remained in the range presented in the literature. Regarding Compressive Strength, the mortars with replacement of 5%, 10% and 15% showed average values of 7.57 MPa, 6.52 MPa and 6.07 MPa, respectively. Mortars with ECT showed a low rate of Water Absorption by Immersion, when compared to literature data. The statistical analysis revealed that all properties studied have strong correlation with the percentage of ECT replacement. The SEM of the Fractured Surface found the highest number of voids and the presence of microcracks in the samples with the highest percentages of ECT. Finally, the accomplishment of this study proved to be relevant in the context of the development of new technical materials, presenting to the market the mortar with triturated post-consumer carton packages.

    (INSTITUTO FEDERAL DE ALAGOAS - Ifal, 2016-06-06) Drigo, Edmara dos Santos; Oliveira, Cristiano Lessa de; http://lattes.cnpq.br/1436093029977246; Ávila Filho, Salvador; https://orcid.org/0000-0002-5006-1501; http://lattes.cnpq.br/8080668192694401; Marques, Sheyla Karolina Justino; https://orcid.org/0000-0001-7554-2275; http://lattes.cnpq.br/3917387578549073; Costa, Israel Crescencio da; http://lattes.cnpq.br/7663274879776157; Esquerre, Karla Patricia Santos Oliveira Rodríguez; https://orcid.org/0000-0001-8799-7365; http://lattes.cnpq.br/1956096628005272; Fleming, Paulo Victor; http://lattes.cnpq.br/1313976268089270
    Communication in organizations is still a difficult obstacle to be transposed. Effective instruments for transmission of information and the advent of technologies still need to rely on motivational and highly subjective factors that will make a man in his job routine report abnormalities or shut. Considering the operator discourse as a valuable tool for abnormalities display operational plan and support for decision-making in the management field, this dissertation aimed to analyze the communication between operators and shifts in a Water Treatment Plant (WTP) in the Northeast of Brazil. Problems in the information flow can result in operational failures in this case represent a risk to public health. The qualitative and quantitative analysis of records of operators and their communication tool show weaknesses in the shift book format used in WTP in question. The analysis of the text written by the operators based on analytical categories of Critical Discourse Analysis suggests the existence of conflicts that affect the organizational climate. We proposed a model instrument for communication in turn in checklist format to replace the typical procedure in narrative style. Although the focus of this work is the written speech, the operator’s speech in all its forms, can contribute significantly to the management system, but this management style should consider issues relating to human reliability and be willing to make procedure and structural changes.

    (Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2023-11-30) Tenório, Arthur Amaral Batista; Marques, Sheyla Karolina Justino; http://lattes.cnpq.br/3917387578549073; Rapôso, Áurea Luiza Quixabeira Rosa e Silva; http://lattes.cnpq.br/7600867517446003; Peres, Ana Paula da Silva; http://lattes.cnpq.br/9975840346577976
    In this study, the sustainable reuse of Sururu shells (Mytella falcata) in civil construction was explored, highlighting not only the approach to environmental problems resulting from inadequate disposal, but also the promotion of local partnerships that generate jobs and boost the regional economy. The present invention consisted of analyzing the interlocking floor with partial replacement of the fine aggregate (natural medium sand) with grains of Sururu shells. A sustainable approach was sought, analyzing technical, economic and environmental feasibility. Detailed physicochemical analyzes were carried out, including Granulometry, X-ray Fluorescence (XRF), X-ray Diffraction (XRD) and Thermogravimetric Analysis (ATG), to characterize the properties of the shells. When defining the concrete mix, a volume ratio of 1:2.33:0.37:2.00:0.43 (cement: sand: crushed stone powder: crushed stone 0: water) was established. Various sand replacement formulations were also examined, varying between 2.5%, 5.0%, 7.5% and 10.0%. During laboratory tests, the results met technical specifications favorably. The C-5% composition presented a compressive strength of 37.87 MPa, meeting the technical requirements established by the standard for concrete pieces intended for paving, which requires resistance equal to or greater than 35 MPa. Water absorption tests demonstrated effectiveness in promoting adequate drainage, with water absorption variations within the acceptable range, remaining below 0.77%. These results highlighted the potential of Sururu shells as a source of technical, economic and environmental interest in the manufacture of interlocking pavements. This study not only contributed to the development of innovative technical materials in the interlocking flooring market, but also emphasized the importance of sustainable practices in construction and reinforces the Circular Economy.

    Caracterização do recinto de aclimatação marinho para peixes-bois (Trichechus manatus manatus) no Ceará : uma inovação tecnológica para o manejo da espécie no Brasil
    (INSTITUTO FEDERAL DE ALAGOAS - Ifal, 2025-01-23) Bezerra, Brunno Torres de Gouveia; Normande, Iran Campello; Romero, Renato de Mei; https://orcid.org/0000-0001-6196-6122; http://lattes.cnpq.br/9857771457585862; Choi, Katherine Fiedler; Marques, Sheyla Karolina Justino
    For many years, the West Indian manatee (Trichechus manatus manatus) was classified as Critically Endangered in Brazil and recognized as the most vulnerable aquatic mammal in the country. To support its conservation, strategic actions such as rescue, rehabilitation, and release of manatees into the wild have been carried out since 1994 in northeastern Brazil, with the aim of repopulating areas of historical occurrence, reconnecting isolated populations, and strengthening existing population nuclei. As part of these strategies, the Association for Research and Preservation of Aquatic Ecosystems (Aquasis) implemented, in 2020, a new model of a marine acclimatization enclosure in Icapuí, Ceará, pioneering as the only structure of its kind located in a marine environment in Brazil. Consisting of a floating platform with a net-tank system, the enclosure was developed to initiate the acclimatization and release process of manatees rescued and rehabilitated by Aquasis in the state of Ceará, as part of conservation strategies for the species. In 2024, the structure of the acclimatization enclosure was expanded with the installation of a surrounding fence, forming a polygonal contour area resembling a traditional fish corral, encircling the floating platform throughout the perimeter of the polygon. This study aims to characterize the marine acclimatization enclosure used for manatee adaptation in Icapuí, Ceará, as well as to analyze other existing acclimatization enclosures in Brazil. The research compares different manatee acclimatization systems used in the country, detailing their construction features—including the floating platform and fence—describing feeding management practices, capture and handling methodologies, developing a schematic representation of the acclimatization enclosure, and proposing improvements aimed at enhancing animal welfare. The implementation of the marine acclimatization enclosure represents an innovative and strategically important structure for manatee conservation, highlighting its operational features. The results underscore the Icapuí marine acclimatization enclosure as an innovative and replicable model with the potential to expand the positive impact on species conservation.

    Metodologia para produção de moradia em assentamentos urbanos informais com incorporação de Tecnologia Social: estudo de caso na Favela Sururu de Capote no Município de Maceió/AL
    (Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2022-01-25) Vitorino, Natiele Vanessa; Cunha, Mônica Ximenes Carneiro da; http://lattes.cnpq.br/1775024859845111; Cavalcanti, Fernando Antonio de Melo Sá; http://lattes.cnpq.br/4407657668950931; Marques, Sheyla Karolina Justino; http://lattes.cnpq.br/3917387578549073
    Housing shortage is one of the biggest urban challenges in Brazil. Because of it, many families have been build precarious housing in clandestine or environmentally fragile areas, despite the housing programs that have been developed over the years, as the Favela Sururu de Capote, in Maceió/AL. Community involvement searching by solutions is fundamental to generate protagonism and social inclusion. Social Technology (ST) emerges in this context and involves of products, methods and techniques produced in interaction with the community and appropriated by them, uniting traditional knowledge with technical-scientific knowledge. Social Technology (ST) incorporation in housing is still an atypical topic among researchers. This work objective to propose a methodology for the production of housing in informal urban settlements with the Social Technology incorporation. As a research strategy, a qualitative approach was chosen. The methodological course involved three stages: (1) Systematic Literature Review (SLR); (2) Rapid Participatory Urban Diagnosis (DRUP); and (3) Proposal for a methodology for the production of housing with ST incorporation. By the SLR results, it was found that the ST incorporation in the housing problem is a recent theme. It was also possible to identify indicators, some technologies for houses construction and tools for data collection, like the DRUP. By the field research, it was possible to identify the social and environmental community problems and make the residents' needs survey. From the data obtained, it was possible to list indicators related to environmental and social aspects. In turn, the indicators found in the RSL and those defined from the DRUP were fundamental to support the proposed methodology for the production of housing with the ST incorporation, involving four stages: planning, development, application and reapplication. It is expected that the methodology developed in this research can contribute to the production of housing with the Social Technologies incorporation in informal urban settlements.
