This research analyzes the public discourses on education by Renato Feder, Secretary of Education of the State of São Paulo, in order to reveal their managerialist bases and how they operate ideologically. The study builds on the premise that the dissemination of managerialism promotes a progressive colonization of public education by corporate principles, which naturalizes market logic and reduces complex educational issues to mere technical dimensions. It investigates, therefore, to what extent these managerial bases express the contemporary dynamics of semi-formation and the “new spirit” of capitalism. To ground the critique, the framework anchors itself in the Critical Theory of Society, mobilizing the concepts of Culture Industry, formation (Bildung), and semi-formation (Halbbildung) described by Theodor W. Adorno and Max Horkheimer, articulated with the formulations of Luc Boltanski and Ève Chiapello regarding the transformations and justifications of contemporary capitalism. From a methodological standpoint, it adopts Critical Discourse Analysis (CDA) from Norman Fairclough’s perspective, investigating discourse in its textual, discursive practice, and social practice dimensions. The source material gathers two primary sources: the book Educação para o future (Feder, 2023) and the lecture Atuais desafios da educação, delivered by the secretary in November 2025. The results of the analysis are structured around four fundamental axes: the construction of the manager’s discursive legitimacy; the conception of education as management focused on quantifiable goals and results; the relationship between technology and semi-formation through the platformization and monitoring of teaching; and the construction of the desirable subject aligned with corporate and capital demands. It concludes that the discourse closely approaches the notion of the “new spirit of capitalism” by articulating justifications for promoting the incorporation of the logic of capital into the subjects, as well as produces semi-formation by impoverishing the emancipatory character of the school under the guise of modernization.

The microfrontend architecture proposes to bring to the user interface layer the same decomposition logic that microservices brought to the server: splitting a web application into small modules, maintained by separate teams and integrated at runtime. The idea is appealing because it lets each team evolve its part without depending on the schedule of the others. In practice, however, this autonomy hides a class of problems that recent literature has been characterizing, in particular module integration, shared dependency management, inter-module communication and visual consistency. This work investigates these problems empirically. The starting point was a real production incident: TaqShell, maintained by Taqtile, started showing a blank screen after user login, a single symptom caused by four concurrent technical problems, each one matching a challenge already cataloged in the literature on microfrontends. Investigating that incident motivated the construction of a controlled sample system (mfe-example), in which each phenomenon was reproduced in isolation through four experiments focused on CSS conflict, Shadow DOM isolation, shared-dependency incompatibility and MINOR version compatibility breaks. As a central contribution, a script for automated validation of shared dependencies between host and remote microfrontends is proposed, integrated into a GitHub Actions workflow with cross-repository checkout. The solution closes a gap left by Module Federation itself, which is by design a sharing tool, not a validation tool. Applied to TaqShell, the script revealed six version divergences that the existing pipeline had not flagged, and in an open pull request it detected, in real time, the exact failure mode characterized as Problem 3 in this work, blocking the merge until the fix was applied. The results show that theoretically predicted errors, such as major version mismatch, dependencies missing from the shared scope and duplication of libraries with global state, pass silently through the build and only manifest in the end user’s browser, often with error messages that do not point to the root cause.

This study conducted a qualitative and quantitative analysis of the occurrence of learning and attrition phenomena in bilingualism, using Brazilian Portuguese as L1 and Peninsular Spanish as L2 as the linguistic pair, and examining the intonational contours of yes-no questions produced by three groups of speakers: monolingual Brazilians with no knowledge of Spanish, monolingual Spaniards with no knowledge of Brazilian Portuguese, and bilingual Brazilians who have Spanish as their L2. The analysis drew on data collected — and qualitatively analyzed by Silva and Arantes (2022) — from the three groups of speakers reading excerpts from the adaptation for adolescents of the book Don Quijote de La Mancha. In previous studies (Silva, 2016; Silva and Arantes, 2022a; Silva and Arantes, 2022b), three types of utterances were considered: declarative,wh-questions, and yes-no questions. For this study, the focus is on the latter type. The sentence to be analyzed is “¿Amigo Sancho, tienes miedo?” in Spanish and its translation into Portuguese, “Amigo Sancho, tens medo?”. Based on the results of the undamental frequency (f0) contours obtained in the studies by Silva and Arantes (2022a) using the Praat software, it is observed that Spanish speakers produce a rising contour on the word carrying the nuclear stress, whereas Brazilians produce the contour traditionally described as “circumflex”, in which there is an initial rise aligned with the nuclear stress syllable and a fall aligned with the post-stressed syllable. With regard to bilingual speakers, three groups were observed: a first group that replicates the same contours as native Spanish speakers in their L2 production; a second group that transfers the intonational features of Portuguese to the L2; and a third group that ends up blending the other two types. The results obtained revealed low occurrence of attrition in Portuguese, that is, most of the speakers replicated the typical Brazilian Portuguese pattern. The data were then quantitatively analyzed using the Dynamic Time Warping (DTW) technique to determine the distance between pairs of f0 contours. Based on this analysis, it was possible to observe that the contours transferred from L1 to L2 show greater variability than those found in the L1 of Brazilian monolinguals and that the qualitatively typical L1 contours are quantitatively more variable than those produced by native Brazilians.

In this work, we study algebras with polynomial identities (PI-algebras), with particular emphasis on the polynomial identities of the Grassmann algebra. To this end, we develop the necessary background on algebras, free algebras, and T-ideals. In addition to the polynomial identities of the Grassmann algebra, we also present the polynomial identities of the matrix algebras M2(K) and Un(K). Furthermore, we study the T-ideal of commutative algebras and, finally, present a basis for the T-ideal of the Grassmann algebra.

Highly weathered soils from tropical regions have low availability of phosphorus (P) to plants, disfavoring agricultural production, making it necessary to use phosphate fertilizers, due to the high adsorption of P to soil constituents, but the continuous application of these can promote accumulation of P in forms not very available to plants, in addition to causing environmental impacts. Triple superphosphate (ST) is the main industrial source of P used in agriculture, due to the high concentration of this element and high solubility, but the use of P can be limited due to nutrient adsorption processes in the soil. Therefore, it became necessary to adopt forms that would increase the efficiency of the use of P in agricultural systems, such as the use of natural phosphate (FN) sources and green fertilization. In the case of natural phosphates, the supply of P is gradual throughout the development of the crop. Considering green fertilization, it is understood that buckwheat has a high capacity to solubilize phosphates, mobilizing poorly available forms of this element. Therefore, this crop was used to make P available to carioca beans, a characteristic culture because it has a low capacity to mobilize poorly available forms of P in the soil, and this element is essential in its development. The objective was to evaluate the effect of buckwheat biomass on the absorption of P from a FN by carioca beans. In the first trial, the soil incubation was carried out, an ortic Quartzarenic Neosol, with sources of ST and FN, in which the concentration of P and the biomass of buckwheat was evaluated, with or without the planting of buckwheat. After cultivation, its biomass was cut, incorporated into the soil and incubated until its decomposition, and was later used for the cultivation of the bean. In the second test, the biomass of the aerial part, root, leaf length and pod production were evaluated, comparing triple ST and FN, in the presence or absence of buckwheat biomass to the soil, and a source without the addition of P. The results indicated that the ST showed higher performance than the FN in all the variables analyzed, the incorporation of buckwheat biomass did not promote a significant increase in the availability of P for the carioca beans.

The objective of this master's dissertation is to study, under specific assumptions, the existence and nonexistence of weak, nontrivial, and nonnegative solutions to a nonlinear elliptic problem subject, initially, to Neumann boundary conditions and, subsequently, to mixed Neumann–Dirichlet boundary conditions. To this end, we employ classical variational methods from the literature, such as the Mountain Pass Theorem and Mizoguchi’s Theorem, together with fundamental tools from functional analysis. Initially, we investigate the multiplicity of solutions for the problem under Neumann boundary conditions, using the Palais–Smale condition to obtain compactness. Next, we analyze a version of the problem with slightly different assumptions and functional setting, in which compactness is ensured through the Cerami condition. Finally, we study the linear case of the same problem endowed with mixed boundary conditions, namely, Neumann conditions on part of the boundary and Dirichlet conditions on the complementary part.

El término social es polisémico, puede entenderse como concerniente a la sociedad o al conjunto de ciudadanos de un país; en el contexto de la industrialización capitalista, se refiere a las masas menos favorecidas. Los programas de formación en terapia ocupacional en Latinoamérica se fundan a partir de la década de 1950, replicando modelos anglosajones; años después, comienza a reclamarse su insuficiencia para responder a las demandas sociales. Este estudio analiza las maneras como lo social es comprendido en los programas de formación en terapia ocupacional en quince países de América Latina. Se sustenta en la colonialidad, un patrón de poder y dominio del saber que silencia pueblos y reproduce la cultura europea, el capitalismo y las relaciones de subordinación. Asimismo, toma como referentes los aportes de Malfitano, quien analiza el lugar transversal o específico de lo social en la terapia ocupacional, y de Galheigo, quien refiere tres perspectivas en el abordaje de lo social en la profesión: estructural-funcionalista, humanista y crítica. La investigación se desarrolla en tres fases: la primera, una aproximación a la actualidad de los programas de pregrado en terapia ocupacional en los países participantes; la segunda, un análisis documental orientado a identificar propósitos y énfasis de la formación; la tercera parte de 19 entrevistas a docentes y directivas, para analizar tendencias en la comprensión de lo social. Estas tendencias, en diálogo con los contenidos de las asignaturas y el referente conceptual, revelan dos orientaciones. Se identificaron 142 programas de terapia ocupacional activos en los quince países en 2023, el 82 % concentrados en Brasil, Chile, Argentina y Colombia. Se ofrecen mayoritariamente en instituciones privadas, cuyos propósitos suelen centrarse en la calidad educativa, la formación de profesionales competentes para el mercado laboral técnico-clínico y la gestión de servicios de salud. Las asignaturas relacionadas con los énfasis en patologías y biológico tienen mayor peso en los currículos, seguidas por aquellas vinculadas al énfasis social y en procesos y marcos basados en la ocupación y la actividad. Se identificaron ocho tendencias en la comprensión de lo social: lo que no es biológico y no son técnicas; lo que no es individual; es llevar intervenciones al territorio; lo que se sale del currículo; es mirar al sujeto en su contexto; qué de lo comunitario es social; la centralidad en la ocupación; es transversal en el currículo. Estas tendencias muestran, finalmente, dos orientaciones en la comprensión de lo social, denominadas: “lo social en la terapia ocupacional” y “las terapias ocupacionales críticas”. En la primera, lo social es un elemento transversal que se integra en las asignaturas de los diferentes énfasis con referentes como los derechos humanos; esta orientación se identifica con las perspectivas estructural-funcionalista y humanista, privilegia intervenciones individuales en contextos sociales y un rol del terapeuta ocupacional como adaptador. En la segunda, lo social llega a diferenciarse como subárea de conocimiento y actuación basada en enfoques críticos y de la sociedad, dirigida a poblaciones sin soporte social con acciones colectivas en contextos donde el terapeuta ocupacional asume un rol transformador.

This work presents the development and comparison of conventional PID, Fuzzy-PID, and Neural-PID controllers applied to the speed control of a direct current motor subjected to reference changes and load variations. The study aimed to evaluate whether adjusting the PID gains through fuzzy logic and a neural network could improve system performance compared with the use of fixed gains. Initially, the main electrical and mechanical parameters of the experimental setup were identified and used to obtain the mathematical model of the motor and to perform simulations in MATLAB. The controllers were evaluated in eight simulated scenarios involving different load levels, successive reference and disturbance changes, and parametric variations of the plant. Subsequently, the three methods were implemented in LabVIEW and experimentally evaluated in six scenarios using a data acquisition device, an analog output conditioning circuit, and a virtual load inserted into the control signal path. The comparison was based on metrics such as rise time, settling time, overshoot, maximum speed drop, recovery time, integral error indices, and control effort. In the simulations, the Fuzzy-PID and especially the Neural-PID showed advantages in disturbance rejection, damping, and robustness against plant variations. In the experimental tests, the conventional PID produced faster responses in several events, whereas the intelligent controllers showed specific advantages through overshoot reduction, lower control signal variation, and more damped responses. It is concluded that none of the methods was superior under all evaluated conditions. The PID controller proved suitable for operating conditions close to its nominal tuning and for applications that prioritize speed and simplicity, while the Fuzzy-PID and Neural-PID presented advantageous characteristics when smoother responses, gain adaptation, and lower sensitivity to certain operating changes are required

This Final Coursework explores the relationship between linguistics and philosophy, focusing on the works of Immanuel Kant, Mikhail Bakhtin, and Mattoso Câmara Jr., through a comparative study centered on the philosophy of language. The core issue under debate is the persistence of historiographical stereotypes in Brazilian academia (such as viewing Bakhtin as a “historical materialist,” Kant as an “idealist,” and Câmara Jr. as a “structuralist”), which limit a factual understanding of their contributions, as noted in prior studies. The general objective is to demonstrate whether a comparative approach to the works Critique of Practical Reason (Kant, 2016[1788]), Principles of General Linguistics (Câmara Jr.), and Toward a Philosophy of the Act (Bakhtin, 2010[1984]) fosters a more precise understanding of their ideas. As specific objectives, it proposes: a) to investigate interpretations that lead to misunderstandings of their works; b) to identify concepts that facilitate approximation between the authors; c) to compare the role of theoretical presuppositions in this connection; d) to assess whether this effort results in a more faithful interpretation. The research is classified as comparative, confronting the selected works to challenge current ways of understanding them; it is also historical, documentary, and bibliographic, reconstructing their intersections and reviewing prior studies. Theoretically, it draws on Fricker (2023) regarding epistemic injustice applied to Brazilian linguistics. The analyses reveal deep connections between the works, questioning stereotypes and identifying concepts such as subject, act, and event that enable a more faithful reinterpretation, especially of Bakhtin’s profile, distinct from the predominant view.

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.

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.

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.

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.

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.

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.

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.

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.

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.

This qualitative research study draws on a collaborative and interpretive perspective, articulating teacher education processes, knowledge production, and teacher professional development to understand the factors that influence the professional growth of female teachers who teach Mathematics in the early years of Elementary Education. In this context, the research was guided by the following question: how does the professional development of female teachers who teach Mathematics in the early years of Elementary Education take shape within a shared teacher education group, considering their formative trajectories and the reflective and collaborative processes produced within it? Data were produced through narrative interviews conducted with the participants and eleven Shared Professional Development Meetings, held between November 2023 and July 2024, at a public school located in a city in the interior of Minas Gerais. The formative meetings were organized based on demands presented by the teachers themselves and addressed topics related to the teaching of Mathematics in the early years of Elementary Education, such as the Decimal Number System, Problem Solving, Geometry, the use of Digital Information and Communication Technologies (DICTs), and pedagogical planning. The research sought to understand the factors that influence the professional development of the female teachers and to analyze the reflective processes produced in the context of shared teacher education. The study is grounded, among other authors, in Marcelo García (2009; 2011), Nóvoa (1992a, 1992c), Tardif (2011), Zeichner (1993), Gatti and Barreto (2009), Passos and Nacarato (2018), Cyrino and Grando (2022), and Pereira and Anunciato (2023), in addition to engaging in dialogue with normative documents related to teacher education in the Brazilian context. Data analysis made it possible to identify three axes that influence the professional development of the participants: (1) the constitution of professional development in the teachers’ narratives; (2) the process of reflection and collaboration in the shared professional development meetings; and (3) the voice of school management regarding teacher professional development: tensions and possibilities. In addition, it showed that the shared professional development meetings constituted spaces for dialogue, reflection, and exchange of experiences regarding the teaching of Mathematics, favoring the explicit articulation of beliefs, conceptions, and challenges related to teaching practice. The results demonstrate that teacher professional development constitutes a complex process, marked by the articulation between personal experiences, formative trajectories, family support, working conditions, and opportunities for reflection on practice. The shared teacher education meetings favored the problematization of experiences, the circulation of professional knowledge, and reflection on the teaching of Mathematics, although they were also intersected by institutional challenges and the concrete conditions of teaching work. Therefore, the thesis is that the professional development of female teachers who teach Mathematics in the early years of Elementary Education is constituted progressively through the articulation between personal and professional trajectories, formative trajectories, working conditions, institutional support, and opportunities for reflection and collaboration, with shared teacher education playing an important role in the problematization of practice and the production of professional knowledge. It is concluded that contextualized formative processes, constructed based on teachers' demands and supported by consistent theoretical frameworks, may foster the professional development of female teachers who teach Mathematics in the early years of Elementary Education.

Eliminating tuberculosis as a public health problem is necessary and possible, but it has faced operational and other challenges in healthcare services and public policies. One of the strategies to eliminate the disease, which currently has low coverage in the city of Teresina-PI, is the treatment of Latent M. tuberculosis Infection (LTBI). To help with this, an alternative model for monitoring and tracking the Latent Tuberculosis Care Cascade (LTCC) was proposed and tested, aiming to increase healthcare coverage for LTBI. Through a longitudinal intervention study, a controlled, paired, and randomized operational trial was conducted. Fifty-two contacts of laboratory-confirmed bacilliferous tuberculosis cases from 11 Primary Health Care Units (PHUs) in Teresina - Piauí were followed using this alternative model, which consisted of standardized guidance recorded in the Citizen’s Electronic Health Record (PEC) in real time for each of the steps of CCTL. In 11 other UBS in the same health region, the conventional surveillance model was maintained over 27 contacts. In the 22 UBS, demographic data of these contacts and a set of care coverage indicators at each step of CCTL were collected. The indicators collected in the group of UBS where the new surveillance strategy was applied were statistically compared to the same indicators in the group of UBS where the conventional model was maintained. Of the total people studied, most were female and of black race/color. The average age was 33.5 years. The proportion of contacts who had a chest X-ray, who took the 1st tuberculin test and the 2nd tuberculin test when indicated, who were fully examined and who started preventive tuberculosis treatment was higher in the UBS where the alternative active CCTL surveillance model was applied. A statistically significant difference (p < 0.05) was reached in the indicators: proportion of contacts who underwent chest X-ray, who undergo the 2nd tuberculin test when indicated, and the proportion of contacts fully examined. This result showed that the tested model is effective in helping fight tuberculosis because it significantly increases healthcare coverage for latent TB infection.
