Sob o sol não somos companheiros? articulações transespecíficas e de gênero a partir de concepções Tukano do sangue menstrual e da gestação
(Universidade Federal de São Carlos, 2026-07-17) Moreira, Larissa Lombardi; Andrello, Geraldo Luciano; http://lattes.cnpq.br/5447074379881029; http://lattes.cnpq.br/5593857249082706; Oliveira, Melissa Santana de; Rodrigues, Raphel; http://lattes.cnpq.br/2774453833513018; http://lattes.cnpq.br/5658153163114667
This dissertation was developed with the aim of reflecting on the position occupied by indigenous women at the intersection of domestic and political-ritual spheres. Drawing on themes related to women’s daily activities, I sought to understand how gendered roles and knowledge are articulated to ensure the reproduction and continuity of Tukano-speaking clans in the Uaupés River region, and thereby to investigate whether the extra-human otherness activated in ritual contexts is also present in the exercise of everyday life. This investigation was conducted through a cross-referenced literature review of two sets of works: the ethnographies by Christine Hugh-Jones (1979), Dany Mahecha (2004), and Melissa de Oliveira (2016); and the articles by Geraldo Andrello and João Vianna (2022), Pedro Lolli and Geraldo Andrello (2024), and Geraldo Andrello and Luiz Nascimento (2024), whose formulations were examined in light of the discussions developed by the first three authors and in conjunction with the large-scale comparative work of Luisa Elvira Belaunde (2005). The broader arguments put forward by these authors—briefly introduced in the opening chapter—are explored in depth in chapters two, three, four, and five, which, in that order, consist of reviews of the ethnographies by Christine Hugh-Jones (1979), Dany Mahecha (2004), and Melissa de Oliveira (2016), as well as analyses of issues and hypotheses related to the topic. This approach prompted me to consider the role of the placenta and breastfeeding within the described interweaving and, thus, to examine the issue of women’s participation in the collective reproductive process from other perspectives.

Traditionally, the structural condition of electrical distribution assets is assessed through field inspections and visual analyses conducted by technical teams, a process that is time-consuming and presents limitations for the overall evaluation of the electrical network. In this context, this work proposes the use of image recognition techniques associated with a trained computational model, specifically MobileNetV2, to classify images of concrete utility poles as being in good or poor condition, thereby supporting maintenance assessment. The project was implemented using the Python programming language, open-source libraries for image processing, and a computational model previously trained on the ImageNet dataset. Transfer learning was applied while keeping the layers responsible for feature extraction frozen. A dataset assembled by the author containing 150 images, equally distributed between the two classes, was used. The images were resized, normalized, and subjected to data augmentation techniques. During the evaluation of the test set, the model trained with cropped images achieved accuracies of 95% and 85% for the first and second image distributions, respectively. However, errors still occurred in the identification of poles in poor condition. Based on the results, it was concluded that the proposed approach has potential as an auxiliary inspection tool; however, it is not yet sufficiently reliable for autonomous classification. Therefore, expanding the image dataset and improving data preprocessing procedures are still necessary.

(Universidade Federal de São Carlos, 2026-07-17) Souza, Eduardo Pereira de; Silva, Flávio Henrique da; http://lattes.cnpq.br/1757309852446263; https://orcid.org/0000-0003-3329-4597; http://lattes.cnpq.br/0850771035889805; https://orcid.org/0000-0002-2013-0115; Silva, Flávio Henrique da; Fuentes, Andrea Soares da Costa; Ferro, Milene; Silva, Adilson José da; Moura, Daniel Scherer de; http://lattes.cnpq.br/1757309852446263; http://lattes.cnpq.br/2426157257540389; http://lattes.cnpq.br/3447469350644179; http://lattes.cnpq.br/9970111751569210; http://lattes.cnpq.br/0264232179982467
Polystyrene (PS) is a polymer with versatile physical and chemical properties and a low production cost, used for various purposes. Its growing demand, combined with poor waste management, leads to accumulation in the environment, triggering social and ecosystem problems. This issue is exacerbated because PS is a recalcitrant polymer due to its carbon–carbon (C–C) main chain, which makes its biodegradation in nature difficult. Studies have investigated strategies for the biodegradation of this polymer. It has been found that larvae of certain insects are capable of using PS as a carbon source, a phenomenon correlated with their gut microbiota. For this reason, the larva of Sphenophorus levis, previously observed ingesting expanded polystyrene (EPS), was used to prospect microorganisms and key genes involved in the material’s biodegradation process. The larvae were fed a diet restricted to EPS, and their intestinal microbial diversity was compared with that of larvae fed an artificial diet. It was observed that diversity decreased and the presence of its obligatory endosymbiont became more pronounced. The intestinal contents of the larvae were subjected to enrichment in a mineral medium, whose only carbon source was PS films. Five bacterial strains were isolated from the following genera: Bacillus, Lysinibacillus, Paenibacillus, Cytobacillus, and Raoultella. These were cultivated for 60 days on solid medium in contact with PS films. SEM analysis revealed cavities, cracks, and fissures in the films, and surface atom mapping indicated oxygen accumulation. FT-IR analyses indicated that only Paenibacillus sp. led to the formation of characteristic oxidation functional groups. Gel permeation chromatography indicated that the same strain was able to alter the polymer’s molar mass. To elucidate which mechanisms might be involved in this process, the entire genomes of two strains (Bacillus cereus and Paenibacillus lautus) were sequenced on the Illumina NextSeq 2000. Annotation identified proteins such as multicopper oxidases, ring-cleaving dioxygenases, cytochromes P450 (CYP), and glutathione peroxidases (GPx). CYP102 from P. lautus and the GPxs from both species were cloned and expressed in Escherichia coli. Both GPxs have thioredoxin peroxidase activity. The results demonstrate the potential of the intestinal microbiota of S. levis as a source of microorganisms and enzymes for PS biodegradation.
Compensação de deriva térmica de encoder magnético analógico via software aplicada a compressor hermético para análise de diagrama P-V
(Universidade Federal de São Carlos, 2026-07-17) Valvassore, Felipe Andriotti; Araujo, Luis Antonio Oliveira; http://lattes.cnpq.br/3639906702064630; https://orcid.org/0000-0002-1117-0094
The construction of experimental PV diagrams is fundamental for the reliability analysis of hermetic compressors, since it enables the quantification of the work required by the process the identification of heat transfer losses, and the diagnosis of inefficiencies in the suction and discharge valves. Proper instrumentation of this system requires accurate measurements of the cylinder pressure and the shaft angular position. In this context, magnetic encoders are widely used due to their high resolution and contactless operation. Although magnetic encoders are subject to different sources of error, such as misalignment, electrical noise, and nonlinearities, as well as limitations in repeatability and reproducibility, this work focuses exclusively on thermal drift, as it is an error that can become predominant in applications subjected to large temperature variations, compromising the thermodynamic fidelity of the experimental P V diagrams. These errors arise from temperature-dependent variations in the sensor response, including changes in the signal amplitude and offset, which distort the calculated angle. This work presents a semi-empirical compensation strategy to mitigate the effects of thermal drift in analog magnetic encoders via software. The approach is based on the generation of reference curves under controlled temperature conditions, using a bivariate polynomial regression model of the shaft angle and temperature. The results demonstrate how this thermal phenomenon significantly affects the encoder measurements, particularly at elevated temperatures, leading to severe distortions in the PV diagrams. The application of the proposed method proved to be essential for measurement reliability, since thermal drift can shift the power calculation by approximately 4.25%. This level of error is critical, as it compromises the accuracy of loss segregation and energy efficiency analyses.

(Universidade Federal de São Carlos, 2026-07-17) Accarini, Luíza Gomes; Bonotto, Everaldo de Mello; Rosado, José Antonio Langa; http://lattes.cnpq.br/2183693074268993; https://orcid.org/0000-0002-8765-0764; Nascimento, Marcelo José Dias; http://lattes.cnpq.br/7133572787875912; http://lattes.cnpq.br/0703792611191481; https://orcid.org/0000-0002-2004-7274; Nascimento, Marcelo José Dias; Belluzi, Maykel Boldrin; Fu, Ma To; Moreira, Estefani Moraes; Bezerra, Flank David Morais; http://lattes.cnpq.br/7133572787875912; http://lattes.cnpq.br/4072119689022816; http://lattes.cnpq.br/5313392830234233; http://lattes.cnpq.br/6532566248140862; http://lattes.cnpq.br/3997742141912443
This work investigates the long-time dynamics of an autonomous coupled Klein-Gordon-Zakharov type wave system defined on a bounded smooth domain in Rn, for n ≥ 3. We establish global well-posedness of solutions in a suitable phase space by employing semigroup theory and we proceed to derive the dissipative properties required in order to construct the associated dynamical system. The asymptotic behavior is then analyzed in detail. We prove the existence of a global attractor, we study some properties for it, such as regularity and upper semicontinuity, and we show that it possesses finite fractal dimension. We also construct exponential attractors for the semigroup generated by the wave system through two different approaches.

(Universidade Federal de São Carlos, 2026-07-17) Laurenti, Thaís Cristina; Mascarenhas, Silvia Helena Zem; http://lattes.cnpq.br/0185144417072417; https://orcid.org/0000-0001-7753-6725; http://lattes.cnpq.br/9862214160954461; https://orcid.org/0000-0001-9030-3846; Pereira, Marta Cristiane Alves; Roseira, Camila Eugenia; Figueiredo, Rosely Moralez de; Cherman, Chris Mayara Tibes; http://lattes.cnpq.br/8950635510987873; http://lattes.cnpq.br/6191593587072537; http://lattes.cnpq.br/2597491235073085; http://lattes.cnpq.br/0978970762996625; https://orcid.org/0000-0002-0563-215X; https://orcid.org/0000-0002-9114-6579; https://orcid.org/0000-0002-0131-4314; https://orcid.org/0000-0002-6653-4609
Objective: To develop an instrument for assessing surgical patient experience and obtain initial evidence of content validity. Method: A methodological study with a quantitative approach, conducted in the following stages: establishment of the conceptual framework, instrument development, content evaluation by expert judges, and pretesting. The conceptual framework was based on a scoping review conducted according to the recommendations of the Joanna Briggs Institute and on the analysis of international instruments. The review identified 2,920 records; after removing 1,398 duplicates, 1,522 records underwent screening, 136 were assessed in full text, and 104 studies comprised the final sample. The synthesis of evidence supported the definition of six dimensions and the development of an initial set of 30 items. Content evaluation was performed by eight expert judges using the Item-Level Content Validity Index (I-CVI) and the mean CVI of the dimensions. Pretesting was conducted with 21 patients who underwent elective surgical procedures. Results: Following expert evaluation, the instrument was refined to 33 items distributed across the following dimensions: Communication, Patient-Centered Care, Perioperative Journey, Perceived Safety of Care, Quality of Care, and Overall Experience. Mean CVI values across the dimensions ranged from 0.82 to 1.00 for clarity, 0.95 to 1.00 for relevance, and 0.95 to 1.00 for pertinence. During pretesting, 90.5% of participants rated the instrument as excellent, 9.5% as good, and 100% stated that they would recommend its use. Conclusion: The instrument, comprising 33 items distributed across six dimensions, demonstrated favorable initial evidence of content validity and adequate comprehension by the target population. Further studies are needed to evaluate additional measurement properties.
Arquitetura genética do holobionte Nelore (Bos indicus): implicações em fenótipos de desempenho e de temperamento
(Universidade Federal de São Carlos, 2026-07-17) Rojas, Liz Jiannine Fuentes; Lourenço, Daniela Andressa Lino; http://lattes.cnpq.br/6181548260327124; https://orcid.org/0000-0003-3140-1002; Regitano, Luciana Correia de Almeida; http://lattes.cnpq.br/9595338480545794; https://orcid.org/0000-0001-9242-8351; http://lattes.cnpq.br/7100367976301028; https://orcid.org/0000-0003-0439-5196; Ibelli, Adriana Mércia Guaratini; Cunha, Anderson Ferreira da; Regitano, Luciana Correia de Almeida; Sudano, Mateus José; Tholon, Patricia; http://lattes.cnpq.br/4729789236742545; http://lattes.cnpq.br/0329741640375661; http://lattes.cnpq.br/9595338480545794; http://lattes.cnpq.br/1945811068525845; http://lattes.cnpq.br/4344301494520180; https://orcid.org/0000-0003-0626-8879; https://orcid.org/0000-0003-3485-5659; https://orcid.org/0000-0001-9242-8351; https://orcid.org/0000-0002-7699-4449; https://orcid.org/0000-0001-7642-1352
Beef cattle production is one of the main pillars of Brazilian agribusiness, with emphasis on the Nelore breed (Bos indicus), which is widely adapted to tropical conditions. Despite advances in genetic improvement, productive and temperament traits exhibit low to moderate heritability, indicating that the phenotypic variation of these traits is not fully explained by host genetics. In this context, the gastrointestinal microbiota has been recognized as an important modulator of metabolism, feed efficiency, productive performance, and behavior-related traits in ruminants. The interaction between host genetics and the microbiome constitutes a relevant component in the expression of complex phenotypes, with microbiability being used as a complementary measure to genetic heritability. However, its application in beef cattle, particularly in Nelore populations, remains limited. Thus, this thesis aimed to investigate host-microbiome interactions in Nelore cattle, evaluating the influence of host genetics on the fecal microbiota and its associations with performance and temperament traits in young bulls. For this purpose, 16S rRNA gene sequencing was performed for taxonomic characterization of the fecal microbiota, integrated with host genomic information. Associations between microbial features and performance traits were evaluated using linear mixed models, whereas host-microbiome interactions were investigated using genomic linear mixed models and hierarchical Bayesian models to estimate the heritability of microbial features, identify host genetic variants through genome-wide association studies (GWAS), estimate heritability and microbiability of performance and temperament traits, and evaluate genetic and microbial correlations. Significant associations were identified between elements of microbial composition and phenotypes, including ribeye area, metabolic weight, and EPMURAS, highlighting the role of the microbiota in animal performance. Additionally, a portion of microbial abundance features exhibited measurable heritability, with the identification of genetic variants associated with the microbiota and candidate genes potentially involved in host-microbiome interactions. Heritability estimates were moderate to high, indicating a strong influence of host genetics on the evaluated phenotypes. In contrast, microbiability showed low magnitudes, although with a relatively higher contribution to some traits related to feed intake, morphology, fat deposition, and temperament. Furthermore, the microbiota influenced associations among temperament phenotypes, showing correlation patterns distinct from those observed for host genetic effects. Overall, the results obtained enhance the understanding of interactions between host genetics and the microbiome in beef cattle, indicating that the microbiota may act as a complementary component of phenotypic variation and be incorporated into genomic evaluation models, contributing to more efficient and sustainable genetic improvement strategies.
Aesthetics punk em discurso: efeitos de sentido no Instagram sob a perspectiva da Análise do Discurso Digital
(Universidade Federal de São Carlos, 2026-07-17) Tonhatti Ciniello, Giulia; Fernandes Araújo , Dandara Rochelly; http://lattes.cnpq.br/3509447023315693; https://orcid.org/0009-0006-1235-2988; Nogueira, Luciana; https://lattes.cnpq.br/7475342844385424; https://orcid.org/0000-0003-4470-5005; http://lattes.cnpq.br/4181355889127433; https://orcid.org/0009-0004-9089-1800
Currently, "aesthetics" are considered a phenomenon in digital culture that fosters a sense of identification between individuals and visual elements. Thus, this research aims to analyze the meaning effects produced by the circulation of the "punk aesthetic" on Instagram, drawing on Digital Discourse Analysis — specifically the formulations of Marie-Anne Paveau (2021) and Cristiane Dias (2016) — while considering its modes of constitution, formulation, and circulation (Orlandi, 2001), as well as the modes of subject constitution within these spaces. To this end, concepts from Materialist Discourse Analysis and Digital Discourse Analysis are employed, including conditions of production, discursive memory, metallic memory, techno-discursive memory, and the archive, as defined by Orlandi (2015), Leandro-Ferreira (2020), and Paveau (2021). Specifically, we analyze excerpts from Instagram posts related to the punk aesthetic, seeking to understand the meaning effects produced when this aesthetic circulates as a techno-discourse. The corpus was compiled from Instagram posts and materials from the Aesthetics Wiki, a collaborative platform dedicated to cataloging and describing aesthetics. Methodologically, the research is grounded in the notion of the "excerpt" proposed by Orlandi (1984), viewing the corpus as a set of interconnected discursive materialities interpreted and analyzed through the theoretical framework of Discourse Analysis. Through this work, we hope to contribute to discussions regarding the production of meaning associated with aesthetics in digital spaces and to reflections on subject constitution within contemporary digital materialities.
Educação ambiental no ensino de Física Térmica: uma análise dos livros do PNLD 2026 à luz da BNCC
(Universidade Federal de São Carlos, 2026-07-17) Messias, Mariana Paula Martins; Souza, James Alves de; http://lattes.cnpq.br/2212240621620011; https://orcid.org/0000-0003-0112-8332; http://lattes.cnpq.br/6114357180488505
Environmental Education is a cross-cutting theme established by Brazilian educational legislation and by the National Common Curricular Base (BNCC), requiring different fields of knowledge to contribute to students’ scientific, civic, and socioenvironmental education. In this context, Thermal Physics has considerable potential for discussing phenomena related to energy transformations, climate change, the use of fossil fuels, and energy efficiency. Accordingly, this study aimed to analyze how Thermal Physics contents presented in Physics textbooks approved by the 2026 National Textbook and Teaching Materials Program (PNLD) incorporate the principles of Environmental Education and promote contextualized and critical learning about contemporary environmental issues. The research is qualitative in nature and based on documentary analysis, adopting Bardin’s Content Analysis as its methodological framework. The corpus consisted of the textbook collections Física por Toda Parte and 360° Física, analyzed in light of the conceptual foundations of Thermal Physics, the principles of Critical Environmental Education, and the guidelines established by the BNCC and the Pedagogical Framework of the PNLD 2026. The material exploration was organized into three analytical dimensions: conceptual, didactic-pedagogical, and formative. These dimensions enabled the identification, coding, and interpretation of recording units related to content organization, conceptual accuracy, teaching strategies, the integration of Environmental Education, and the alignment with the competencies and skills established by the BNCC. The results indicate that both textbook collections have the potential to promote the integration of Thermal Physics and Environmental Education, although through different pedagogical approaches. The Física por Toda Parte collection incorporates environmental discussions more consistently throughout the development of scientific concepts, whereas 360◦ Física concentrates these discussions mainly in text boxes, supplementary texts, and contextualization activities. The analysis also identified terminological inconsistencies, particularly concerning the concept of heat, in both collections, although these occurred more frequently in Física por Toda Parte, highlighting the need for greater conceptual rigor in the development and revision of these teaching materials. It is concluded that the educational potential of textbooks depends not only on the inclusion of environmental themes but also on how these themes are integrated into conceptual development and on the critical mediation provided by teachers. In addition to answering the research question, this study demonstrates the contributions of Bardin’s Content Analysis as a methodological approach for investigating educational materials, reinforcing its relevance for initial teacher education and for the critical evaluation of resources used in Physics teaching.
