Verticalisation and integration are fundamental assumptions of the education offered by Federal Institutes. However, the concept of verticalisation, as well as its organisation and potential in education, is not well defined. Thus, through this research, based on the contributions of polytechnic training and the school of work, developed by Soviet thinkers and Gramsci, we sought to define the conceptual understandings of verticalisation contained in internal documents related to the technological axis of Natural Resources at IFSP-Campus Barretos, as well as in internal documents related to the Campus itself and IFSP. To this end, the concepts contained in the specific literature on the subject were defined in order to present possible clarifications in the different understandings of the concept. Furthermore, contributed directly to the development of a broad concept of verticalisation, which presents it as linked to the fundamentals of omnilateral, integral and polytechnic training of workers, as well as understanding its organisation in the pedagogical and administrative-managerial dimensions, and assumes the possibility of the occurrence of verticalised training both externally and internally to the institution, in the search for the formation of a new ruling class. Based on these concepts, and on the contribution to the conceptual development itself, the institutional documents were analysed from the perspective of Historical-Dialectical Materialism, based on the analysis of the context. The selection of documents took place both internally and externally to the Campus, where internal documents were selected between 2010 and 2023, beginning with the founding of the IFSP-Campus Barretos. Specifically, for documents internal to the technological axis of training in Natural Resources, documents issued between 2017 and 2023 were selected, since this period included the opening of higher education in Agronomy, which guaranteed the basic condition for the verticalisation of the axis studied and culminated at the end of the 2019-2023 Institutional Development Plan period. Through analysis, a narrow understanding of verticalisation was evident in the internal documents of the Campus and the Axis. At the same time, the deterioration of the concepts of integration and verticalisation in the documents over time was demonstrated. Furthermore, it was demonstrated that conceptual deterioration occurs at an accelerated rate in documents prepared by the rector's office from 2022 onwards, transforming verticalisation into a synonym for simplified training, based on the use of knowledge obtained in technical courses at secondary level as equivalent to higher education knowledge. Internally within the axis, although the conception of verticalisation contained in the documents is narrow, the occurrence of verticalisation in the Natural Resources axis is evident, with internal and external training courses taking place on campus. In addition, actions linked to the pedagogical dimension that could potentially promote internal verticalisation within the axis studied were identified and characterised. It is hoped that this research will enrich the debate on verticalisation, its potential and its impact on the training of the working class, preferably that linked to the precepts of polytechnic training.

This work is an environmental geomorphology research that was based on the geomorphological analysis of the Tatuí River Watershed, located in the southeastern portion of the state of São Paulo between the municipalities of Tatuí, Itapetininga, Guareí, and Quadra. In addition to the geomorphological analysis elaborated from the identification of landform patterns, the research also addressed the main environmental impacts that occur in the watershed, integrating them into the analysis of Environmental Fragility. The methodology used in this work was based on theoretical references from Geomorphology and Geography, dealing with the taxonomic classification and levels of approach to relief. The Systemic Approach was chosen as the conceptual foundation for the problematization and interpretation of the observed data. The adopted methodology comprises the set of techniques and procedures applied during the analysis, serving as a basis for conducting the research. There was a bibliographic review of the theme, elaboration of thematic maps, and fieldwork. As a result, it was found that in the referred watershed there are 5 (five) units, whose diverse characteristics are, in general, related to the different rocks found in its territory. Furthermore, the lithological contacts themselves impose conditions on the action of the area's drainage network, establishing different levels of dissection. Structural aspects, such as faults and diabase dikes, also influence the regional relief and, consequently, the landscape of the basin. Allied to these characteristics, different activities related to land use were observed in the Tatuí River Watershed, focusing on elements related to the urban area, the impact of soil sealing and surface runoff, which frequently result in flood events and mass movements.

The preservation and qualification of rural areas and small farms (chácaras) is of utmost importance for the proper management of water resources, avoiding or minimizing problems caused by water scarcity or excess, which tend to worsen with climate change. Urban policy in Brazil, established in 1988 by the Federal Constitution and regulated in 2001 by the City Statute, provides instruments to guide land use and occupation in municipalities and is based on the municipal master plan for urban development. The present study aims to investigate the change in zoning in rural areas and urban farms in the municipality of Sorocaba, following the review of the municipal master plan in 2014. The methodology was divided into three stages, according to the specific objectives: a) to identify, quantify, and qualify the altered areas through comparative analysis between the zoning and environmental macrozoning maps from the 2007 and 2014 revisions, using QGIS and Excel software; b) to investigate the criteria for the changes through documentary and comparative analysis between Municipal Laws 8,181/2007 and 11,022/2014, qualitative analysis of the administrative process of the 2014 review, and analysis of the local media by searching for the descriptor “master plan” in the digital collection of Jornal Cruzeiro do Sul from 2014; and c) to investigate changes in land use and occupation that occurred in the territory through the analysis of historical maps on Google Earth. A significant amount of rural and urban farms areas was found to have been altered (approximately 15% of the municipality’s area), most of which were changed to zoning that allows the construction of low-income housing lots, even though a large part is classified in the environmental macrozoning as areas with major restrictions on urbanization. No justifications were found in the law for the changes, only some arguments in the media, and there have been few transformations in the territory even after ten years. It was concluded that the changes were proposed and approved without justification or technical reasoning, that the criteria were limited to meeting the real estate market, and that the changes have not yet caused a major impact on the territory, but their destructive potential is latent.

Distance Education has taken on an increasingly important role in expanding access to public higher education in Brazil, particularly within the scope of federal universities. This thesis aimed to analyze the funding mechanisms adopted by the Brazilian government for the implementation and development of Distance Education programs in Federal Institutions of Higher Education, identifying elements that may contribute to the formulation of improved public policies in this field. A methodological triangulation approach was used, combining both qualitative and quantitative methods. The research included a systematic literature review, analysis of institutional documents, a virtual questionnaire conducted between March 16 and April 16, 2025, and semi-structured interviews with professionals working in the field, carried out between April 17 and 22, 2025. The empirical analysis was organized around four main areas: funding, institutionalization, quality, and the role of the Open University of Brazil. The results indicate that the absence of a continuous funding model undermines the planning and integration of Distance Education into the academic and administrative structures of federal universities. The study also found that the responsible teams and learning centers (polos) face frequent instability in maintaining regular operations, which hinders the consolidation of the modality. Despite these challenges, Distance Education continues to play an essential role by reaching students in regions historically excluded from face-to-face higher education. The analysis showed that although the modality is present in institutions, its continuity still depends on provisional arrangements and temporary decisions. In response, this thesis proposes concrete measures, such as the creation of a dedicated budget line, formalization of tutor roles, and the strengthening of public control over educational technologies. It concludes that the advancement of Distance Education in federal universities requires budget predictability, stable institutional structures, and its inclusion in formal academic governance. More than regulatory frameworks, the lasting presence of Distance Education as part of the public university system depends on political decisions aligned with education as a foundation for social transformation.

Considering the current scenario of perinatal care, experience obstetric violence during pregnancy, childbirth and the postpartum period. Associated with this, maternal mental health has shown high rates of illness and dissatisfaction with the care received may be impacting this situation. Objective: Investigate the impact of obstetric violence on post-traumatic stress disorder in women who gave birth in birthing centers or reference hospitals. Methodology: This study was based on the study "Nascer nas Casas de Parto" the aim was to evaluate the care provided in Birth Centers (BC) and compare it with the care provided in hospitals. The population was postpartum women attended in eight BC in Brazil, with more than 100 births in 2019, as well as the referral hospitals of the BC, in addition to monitored intra and postpartum transfers, also to neonatal transfers. Data collection took place between August 2022 and June 2025, reaching the previously calculated sample of 1,560 participants, incorporating data from healthcare professionals, managers, as well as prenatal care records and medical charts. For this study, data from stages three and four were used, with remote interviews using forms on The City Birth Trauma Scale and on mistreatment and abuse in the BC/Hospital, with the data recorded on the RedCap platform. Data analysis was performed using STATA software, version 17, and through the analysis, the sociodemographic profile, mean and scale scores were described, in addition to calculating prevalence and statistical significance considering p<0.05. The study was approved by the ethics committee and followed the resolutions on research with human beings. Results: 50.4%, of women, suffered some type of obstetric violence, negligence and inadequate vaginal examinations being the most frequently reported. The location where the woman gave birth and needed C-section were the factors that most influenced women to suffer obstetric violence. The City Birth Trauma Scale, with a validated score in Brazil >28, showed black women, without a partner, with a history of psychological problems and who underwent a C-section, had statistically significant mental health alterations. Conclusion: Women who needed to be transferred reported more obstetric violence, in addition to having a higher incidence of alterations in The City Birth Trauma Scale. In contrast, women who have birth in a BC had more positive experiences, with greater autonomy and female empowerment, as well as higher rates of vaginal births and lower rates of unnecessary interventions. Despite this, the study demonstrated the prevalence, even at lower rates, of obstetric violence in BC. Therefore, it is essential to encourage these birthing facilities to reduce C-section rates and promote positive experiences for women and families, while maintaining monitoring and educational practices to address obstetric violence in all care settings.

Chitinases (E.C.3.2.1.14) are enzymes that degrade chitin, a homopolysaccharide found in the cell wall of fungi, in the exoskeleton of insects, and in other lower eukaryotic organisms. Due to their enzymatic role in chitin hydrolysis, insect chitinases play essential functions during molting, cell proliferation, immune defense, and also in obtaining nutrients. This study aimed to isolate and characterize chitinases expressed by the leaf-cutter ant Atta sexdens in two distinct stages of the life cycle: pupa (Quit-ASP) and adult/worker (Quit-ASOA). The extraction of chitinases was performed by macerating 400 mg of ants in 2 mL of 50 mM sodium acetate buffer pH 5.0 containing 0.1% Tween 20. After centrifugation, the supernatant was subjected to three purification steps: precipitation with ammonium sulfate, anion exchange chromatography, and molecular exclusion. The optimal pH and temperature for activity were determined using colloidal chitin as a substrate. Quit-ASOA, which showed an apparent molecular mass of 70 kDa by SDS-PAGE, demonstrated high thermal stability. Furthermore, it demonstrated optimal activity at pH 6.0 and an optimal temperature of 50 °C. Quit-ASP, in turn, showed an optimal pH of 9.0 and an optimal temperature of 55 °C. Both chitinases had their activity increased in the presence of certain metal ions. Mass spectrometry analysis of the primary structure of Quit-ASOA indicated the presence of a chitin-binding domain. This study demonstrated that A. sexdens expresses different chitinases in the pupal and adult stages.

With the advancement of exfoliation techniques for lamellar crystals, the experimental observation of intrinsically quantum physical phenomena in atomically flat materials has become accessible. Among these materials, Group VI transition metal dichalcogenides (TMDs), such as molybdenum disulfide (MoS2), stand out. In its semiconducting form, MoS2 exhibits notable optical properties, such as the intensification of photoluminescence when exfoliated into monolayers due to quantum confinement. By stacking two MoS2 monolayers with rotation angles close to 60°, a moiré superlattice is formed, which allows for the confinement of electrons and holes in different domains. Therefore, these rotated MoS2 bilayers (TBM) with H-type stacking represent a promising platform for the investigation of quantum technologies. The formation of moiré excitons, where electrons and holes are spatially separated and strongly correlated, combined with the application of magnetic fields, creates a physical system of interest. This particular configuration reveals physical phenomena that are still little explored in rotated TMDs. In this work, we report evidence of the optical observation of the Aharonov-Bohm effect in MoS2 TBMs. This quantum interference phenomenon manifests itself through oscillations of the photoluminescence intensity with well-defined periods as a function of the applied magnetic field. Additionally, inversion effects were observed in the polarization of biexcitons in relation to excitonic emission, reducing its intensity by 100%. The results of this work open pathways for the study of new physical properties of superlattices and for the investigation of quantum memory devices and moiré emitters.

Biological control has emerged as a promising alternative to agrochemicals for pest and disease management, driven by the growing demand for more sustainable agricultural practices. Among the microorganisms employed, the filamentous fungus Trichoderma harzianum stands out for its potential in both biological control and plant growth promotion, typically cultivated in solid-state fermentation (SSF) using rice as the main substrate. At the end of the cultivation process, this rice becomes an underutilized residue with no established application. This study evaluated the feasibility of reprocessing this material for reuse in successive cultivation cycles. The residual rice was transformed into a pressable formulation and used as a substrate for a new cultivation cycle of T. harzianum. Spore production, cell viability, physicochemical properties, and the effect of sodium bentonite as an additive to enhance productivity were assessed. Among the main findings, the formulation of residual rice supplemented with 2% bentonite achieved a maximum yield of 1.4 × 10⁹ spores per gram of dry substrate, a level comparable to fresh parboiled rice (2.2 × 10⁹ spores per gram of dry substrate), while maintaining the viability of the microorganism cultivated on the residue. Elemental analysis (CHN) revealed carbon and nitrogen contents similar to those of fresh rice, indicating that additional nutritional supplementation was unnecessary. Overall, the results demonstrate that the reuse of cultivated rice is technically feasible and represents an effective strategy for reducing costs and enhancing sustainability in the production of Trichoderma-based biopesticides, while also contributing to the valorization of agro-industrial residues in biofactories.

Agriculture is an essential sector for the Brazilian economy but faces major challenges in pest control, such as leaf-cutting ants (Atta and Acromyrmex), which are responsible for significant losses in agricultural and forestry productivity. Although synthetic pesticides are still widely used, their side effects on human health, the environment, and non-target organisms drive the search for safer and more selective alternatives. In this work, disposable electrochemical biosensors were developed using acetylcholinesterase (AChE) enzymes extracted from leaf-cutting ants (AsAChE-A and AsAChE-B) and electric eel (EelAChE). The enzymes were immobilized on magnetic particles and applied to screen-printed carbon electrodes. The immobilization process was optimized with the aid of central composite design (CCD), allowing the determination of optimal conditions with 1.4 mg/mL of magnetic particles, 7 µg/mL of AChE, and an immobilization time of 30 minutes. The constructed biosensors demonstrated sensitivity toward the specific inhibitor malathion. The limits of detection (LOD) were 2.6 nM for AsAChE-A and 14 nM for AsAChE-B. These results reinforce the applicability of native enzymes from leaf-cutting ants in analytical devices for inhibitor screening, with potential for the development of selective and sustainable bioinsecticides. The sensors also showed sensitivity and selectivity toward galantamine, another anticholinesterase inhibitor, in addition to being applicable to the screening of microbial extracts associated with ant nests. This proposal proves promising as a tool for the identification of new bioinsecticidal compounds, contributing to more ecological and specific pest control with lower environmental impact.

The National Program of Civic-Military Schools (PECIM), implemented between 2019 and 2022 in the context of Brazilian public education, is configured as the process of militarization of public education at the national level. The investigation stems from the researcher's experience as the director of a school involved in the process of joining the program in the municipality of Sorocaba (SP), marked by mobilizations of the school community, civil society and judicial decisions, but mainly due to the scarcity of studies on the subject. Given the above, the objective is to critically analyze the PECIM guideline in light of the educational principles that underpin public education. To carry out such analyses, a qualitative approach is adopted, and the following data collection sources are used: bibliographic review, bibliographic and documentary research, as well as documentary analysis, outlined by Discursive Textual Analysis (DTA). The study is organized into six chapters, which present: the conceptualization of the terms "military" and "militarization," including in the educational field; historically contextualize management models based on military principles; and investigate the normative and regulatory documents that guide the functioning of the program. Next, the theoretical framework is outlined, based on critical authors such as Freire, Adorno, Saviani, Giroux, Apple, and Libâneo, on the constitutionality of Brazilian education, and the conceptions of the analytical categories—dialogue and democracy—that emerged during the writing of this research are presented. Finally, critical analyses of the program's guidelines are developed, highlighting the program's (mis)steps in relation to educational principles, from the perspective of (anti)dialogicity and (anti)democracy. The conclusion of this work demonstrates that PECIM is an educational model based on the logic of discipline, vertical hierarchy, and control, which contradicts the educational principles that govern Brazilian public education. Although repealed in 2023, PECIM continues to influence state and municipal initiatives, which reinforces the relevance of analytical studies and ongoing debates about the direction of Brazilian public schools.

Capacitive deionization (CDI) has emerged as a promising electrochemical technology for desalination due to its low energy consumption, simple design, and potential for integration with renewable energy sources. However, its scalability and performance are still limited by challenges such as electrode saturation, co-ion repulsion, and slow adsorption kinetics. This thesis presents an integrated approach to enhance CDI performance through the development of new cell configurations, experimental evaluation, and multiphysics simulations. Particular focus was given to the application of ionic diodes and magnetic fields as tools to intensify ion removal and improve process continuity. Ionic diodes were implemented to promote directional ion flow and mitigate electrode saturation, resulting in significant increases in salt adsorption capacity (SAC) and overall system efficiency. The effect of dimensional and operational parameters was systematically investigated, revealing complex interactions governing mass transfer and energy efficiency. Furthermore, this work explored magnetohydrodynamic-assisted CDI, where the application of a magnetic field in conjunction with the electric field induced convective motion via the Lorentz force, intensifying ion transport and accelerating adsorption kinetics. Experimental results, supported by numerical simulations, demonstrated that the application of a magnetic field accelerates the electrosorption process and increases the amount of ions removed from water. The findings presented in this study provide important contributions to the understanding of the physical phenomena governing CDI and propose effective strategies to advance the technology toward sustainable desalination systems, particularly for brackish water treatment.

Endothelial dysfunction is a hallmark of renovascular hypertension and a critical barrier to effective vascular therapies. This study explored the synergistic potential of combining phytotherapy with photobiomodulation (PBM) to restore endothelial function through nitric oxide (NO)-mediated mechanisms. Using the 2-kidney-1-clip (2K1C) hypertensive model in rats, as well as in vitro assays with human endothelial cells and isolated vascular preparations, we evaluated the effects of a standardized combination of Panax ginseng and Angelica keiskei—plants known for their antioxidant and vasorelaxant properties. Intermittent administration of the extract improved endothelium-dependent vasodilation and enhanced NO sensitivity, despite modest effects on blood pressure. When paired with PBM (660 nm), the herbal treatment significantly potentiated vasodilatory responses in aortic rings, an effect abolished by endothelium removal or NO pathway inhibition, suggesting eNOS dependency. Inhibition of eNOS via L-NAME blunted these effects but revealed partial endothelial compensation in acetylcholine responses. Cellular assays confirmed increased intracellular NO and reduced superoxide production, indicating redox balance restoration. Together, these findings underscore a mechanistic interplay between phytotherapy and PBM, driven by eNOS activation and oxidative stress modulation, offering a promising non-pharmacological strategy to counteract endothelial dysfunction in hypertension.

This research investigates how financialization impacts supply chain management, focusing on the case study of LED lamp production in the Industrial Pole of Manaus (PIM), analyzing the effects of tax incentives from the Manaus Free Trade Zone (ZFM) on production structure and logistical efficiency. The methodology combines a systematic literature review and an empirical case study, with the aim of understanding the fiscal advantages and the logistical challenges resulting from production fragmentation. The study reveals that although production in Manaus involves logistical complexities and additional costs related to transportation and inventory management, the fiscal benefits make it a financially advantageous location. The research highlights that the feasibility of production fragmentation or full relocation should be analyzed on a case-by-case basis, considering the specific cost structures of each industry, as dependence on imported materials and the nature of production can directly influence strategic decisions. The dissertation discusses the trade-offs between fiscal benefits and operational efficiency, emphasizing that financial logic guides strategic decisions, often at the expense of logistical efficiency, as the pursuit of cost minimization and maximization of fiscal benefits prevails over the efficient integration of the supply chain. The research offers practical perspectives for managers, highlighting the need for individualized evaluations and suggests areas for future research, such as the comparison between fragmented and centralized production models and the analysis of different industrial sectors under similar fiscal regimes.

This research investigated the instruments and methodological procedures necessary for the development of the higher psychological functions of voluntary attention and the formation of scientific concepts in six-year-old children during Physical Education classes. This study was supported by Historical-Cultural Theory, which postulates that human development is shaped by social interactions, language, and the appropriation of culture in a given historical context. The theory's principles are: the development of the human mind through the appropriation of historically constituted social forms of human activity, effective activity appropriate to the individual, and the development of higher psychological functions that foster self-control and self-mastery. The research aimed: to develop instruments and methodological procedures inherent to the development of the psychological functions of voluntary attention and the formation of scientific concepts, using social role-playing and table/board games; to develop a pedagogical intervention experiment based on the learning needs of the target people; and to discuss the effectiveness of the methodological instrument applied. They used the following methodological instruments: a pedagogical intervention experiment with systematic and participant observation and structured activities aligned with the fundamentals of Historical-Cultural Theory; activities consisting of body tracking and board tracking, human chess and board chess, laterality games, and social role games, to promote social interaction. For systematic observations, we used video recordings and a field diary. The results showed that, in the pedagogical intervention experiment, the integration of bodily experiences and symbolic games favored the development of voluntary attention and scientific concepts, especially when they are mediated by language and conscious action. We emphasize the role of "affinity groups" in organizing relationships among students, which required intentionality on the part of the researcher to foster meaningful mediating activities for learning. The results also showed that the transposition from the concrete to the abstract proved effective, especially when it is anchored in bodily experience. We concluded that intentional pedagogical environments, structured with social role-playing and table/board games, significantly favored the development of voluntary attention and the formation of scientific concepts in six-year-old children. Planned teacher mediation, based on the Action Guiding Framework and levels of assistance, proved effective in promoting the conscious and autonomous internalization of learning, reaffirming the principles of Historical-Cultural Theory and contributing with new perspectives to pedagogical practice in Physical Education.

The advancement of the Internet has resulted in an increase in the continuous generation of data, raising the risks of damage caused by cyber threats. Firewalls play a crucial role in network security by providing protection against these threats. They operate by organizing log records based on specific rules, considering criteria such as the purpose of connections and the policies established by the organization. Updating these rules is challenging, and inadequate choices can lead to security vulnerabilities. Related work on predicting recommended actions for network traffic still employs traditional machine learning methods, where the dataset is static and can be repeatedly traversed, while detecting new patterns requires a new cycle of training, testing, and implementing new models. However, network traffic is continuously captured by a firewall, and its behavior can change both abruptly and gradually. This is common in network environments, where it is necessary to adapt to frequent changes in security policies, network modifications, or new threats. This work proposes the application of the MINAS and Adapted CluStream algorithms to predict recommended actions in network traffic. The logs consist of sessions of network traffic captured by a firewall from an educational institution. Adaptation is necessary for these algorithms to classify the recommended actions (Allow, Deny, Drop, and ResetBoth) in a data stream scenario. CluStream is an incremental algorithm, while MINAS, besides being incremental, specializes in novelty detection. Both algorithms were selected for their specificities and capabilities in learning and evolving the model as new data arrives from the data stream. Experiments conducted demonstrate that both algorithms showed distinct results in the data stream, with satisfactory performance across different metrics throughout the experiments.

Inoculation of cultivars with diazotrophic bacteria such as Azospirillum brasilense can make crops more productive and sustainable, since it reduces the need for nitrogenous chemical fertilizers. However, it is necessary to develop bioinoculant formulations that maintain cell viability for long periods and provide protection against biotic and abiotic stresses. Osmotic, saline, radiation and temperature stresses represent challenges for the prevalence of A. brasilense cells in soil. As an alternative to this problem, the aim is to encapsulate A. brasilense cells in biodegradable matrices through the ionotropic gelation method, characterize the material and assess cell viability during storage. The method consists of forming macrobeads of the matrices containing the microorganism, through the dripping and crosslinking of a polymeric dispersion in a FeCl3 solution. The material chosen was carboxymethyl cellulose (CMC) because it is a renewable, abundant and commercial material and trehalose because of its thermal protection capacity. Beads with a fixed amount of 2.5% CMC and 4 treatments containing 0%, 1%, 5% and 10% trehalose were produced and stored moist at 4 °C and 25 °C; and after drying at 25 °C. The CMC capsules without trehalose showed higher encapsulation efficiency and better viability up to the 15th day of storage at 25 °C. FTIR analysis evidenced the formation of the chemical structure of CMC crosslinking with Fe³⁺, and SEM analysis revealed a regular surface of the spheres. However, the formulation of Azospirillum inoculants requires further investigation, particularly regarding the optimal concentrations of CMC and trehalose and their influence on matrix stability and cell survival during prolonged storage.

Scientific dissemination provides non-specialist citizens with the opportunity to effectively participate in public debates, decision-making, and conscious choices in their daily lives, through inputs provided by the circulation and cognition of contextualized scientific information. In this area, social media stands out by moving from being a source of entertainment to becoming a source of information. TikTok, the object of analysis of this research, stands out as a potential channel for scientific dissemination and has been used by influencers and researchers who are able to quickly approach scientific information for young users who seek content on this platform, often to the detriment of traditional sources of information. This descriptiveexploratory research with quantitative and qualitative approaches has the general objective of investigating Brazilian digital influencers (researchers) who use TikTok for scientific dissemination and analyzing the content (topics) they address. To structure the research, a bibliographic survey was carried out to compose the theoretical framework and select science TikTokers (researchers) – the latter action was carried out in search engines and on the platform itself (TikTok), based on a previous protocol. An alternative model of Bardin's content analysis was applied to collect and analyze the data. The interpretation of the 407 published contents shows that the scientific dissemination model applied on the platform can affect the development of information practices and media competence of followers who consume scientific information. It was clear that not all TikTokers invest in sharing information with references/sources, reducing the possibility of followers developing an interest in the topic/subject outside the platform. When analyzing the content of the TikTokers investigated, it was observed that the narrative structure is maintained to share more contextualized scientific information, especially that categorized as curiosities. Digital influencers, by acting as mediators of scientific knowledge, can play an important role in the democratization of information and in strengthening scientific literacy in digital environments.
