The main purpose of this research was the weaving of a path towards women's literature on the love between women, in which the strength of the lesbian existence (RICH, 1980) present in the works is not ignored or misunderstood. For this, the concept of Lesbian Imagination, coined by Marylin Farwell (1988), was substantiated, expanded, and proposed as a possible reading practice, used, then, in the study of two literary works, Ara (2016) by Ana Luísa Amaral and The Waves (1931/2018) by Virginia Woolf. It started with an enquiry about the female creative process, if there would be something specific in it and in what ways the recognition of this possible specificity would affect the reading of female literary works, especially regarding the presence of the lesbian existence in such works. Thus, with the help of the definition of hermeneutic violence and symbolic clitoridictomy (GARRETAS, 2020) some of the faces of women's silence in patriarchy were portrayed and through the concept of the symbolic maternal order (MURARO, 1994) a route to the dizibility and the free feminine symbolic (IRIGARAY, 1980) was traced. In order to detail the lesbian existence, some narrative and political disputes around the name "lesbian" were presented, with special attention to the conceptualizations of lesbians themselves (CLARK, 1988; RICH, 1980; WITTIG, 1994). The practice of the Lesbian Imagination has been allocated within feminist literary theory as the lesbian dimension of Gynocriticism (SHOWALTER, 1981).

This dissertation, linked to the Graduate Program in Education (PPGE) of the Federal University of São Carlos (UFSCar) along the line "Education in Science and Mathematics", aims to analyze the movement of continuing education in a group of studies with collaborative characteristics, centered on the school, in relation to the development of algebraic thinking in the literacy cycle (1st to 3rd year). It takes as its object of analysis two extension activities offered by the Department of Theory and Pedagogical Practices (DTPP/UFSCar), via a University-School partnership, both related to the work with the thematic unit Algebra in the early years. The methodology, of a qualitative nature with a descriptive-analytical character, describes the experience of the analyzed group from their meetings at two different times: 2019 and 2021. The data production instruments include: 1) document analysis: collection of project reports in partnership with a public school of the state network, photographic collection and written reports resulting from the experiences that took place in 2019; 2) semi-structured interview with three teachers (1st, 2nd and 3rd year) and with the trainer teacher, coordinator of the actions undertaken; and 3) records of virtual interactions via synchronous meetings through Google Meet during the "Classes of Collective Pedagogical Work" (ATPC), which took place in 2021. The results obtained show that although continuing education, in the case studied, made considerable efforts to ensure that the group presented collaborative characteristics, since the formation of the group in 2019, it seems, given the limitations and challenges, when it comes to algebraic thinking, to have walked more in the perspective of problematizing the theme in a movement of reflection on the practice from of theoretical studies centered on the school environment, which contributed to the expansion of the didactic-pedagogical repertoire of the participants. This reality, emerging from countless challenges in the deepening of the theme, reveals a path to follow, which is not the only one, but fruitful: that of collaborative work and its reinvention, transgression and creative insubordination, characteristics that are so necessary in the remote context, for example. In view of the elements presented, a central result is located in the dimension of the professional development of teachers who teach Mathematics in reflective processes that culminated in the possibility of rethinking their actions and better organizing their work with the thematic unit "Algebra" in the early years.

Landscaping is essential for ecological balance, as green spaces are being increasingly occupied with urbanization. It is incongruous that in a country with one of the richest, most diverse and important floras in the world, most of the plants used in landscaping are still exotic, some of which are invasive. With the little appreciation of native species, the urgency of modifying this dynamic is understandable, and analyzing the high rate of urbanization in a global context, the water crisis and the threat of extinction of so many species of fauna and flora, it appears that the Cities must now be seen as ecological entities, where human action must try to reestablish the local environmental balance. Since the State of São Paulo is the most urbanized place in Brazil, concentrating the largest contingent of population residing in urban areas, in addition to the presence of two threatened biomes, Atlantic Forest and Cerrado, we limit one of its most economically significant Metropolitan Regions as an object of study, the Metropolitan Region of Sorocaba (RMS), in order to carry out a survey of local landscape demand and which are the main species offered in regional commerce in the scale of production, sale and management, identifying the groups with the highest output and if there is a market for herbs, shrubs and local native trees for ornamentation, and what material is currently available to promote this sector. The methodology focused on bibliographic research to understand the importance of biodiversity in urban gardens, and quantitative and qualitative research in the floristic market of this regional cut, as well as data collection of working professionals and population profile on the subject, with the purpose of understanding if there is a demand for these vegetations and how their supply and availability in nurseries and floras works. Thus, the standardization of landscapes in the region was verified, where the most offered plants are exotic and little diverse, and the professionals responsible for the projects have an aesthetic vision in disagreement with the population sample studied.

To minimize the effects of ethanol inhibition, increase productivity, and reduce energy and environmental footprint, different strategies of ethanol removal by gas stripping with CO2 during alcoholic fermentation have been studied. However, there are a few studies on how to efficiently recover the ethanol removed by stripping, which becomes difficult the application of this technique. In the present work, an integrated process of ethanol production by extractive fermentation with CO2 stripping and ethanol recovery by the association of adsorption and absorption processes was developed. Firstly, an analytical methodology based on the combination of Fourier transform mid-infrared spectroscopy (FT-MIR) with the partial least squares multivariate regression (PLS) method was developed to monitor the gas phase containing water and ethanol. Then, the water and ethanol adsorptive capacities of the 3A (Z1, Z2, and Z3) zeolites and cassava sago adsorbents were evaluated in an up-flow packed column to select the most suitable adsorbent for dehydration of the gas stream from stripping of hydroalcoholic solutions and extractive fermentations. The next step was to evaluate different strategies of association of the adsorption and absorption (with monoethilene glycol, MEG) processes using extractive fermentation experiments operated in fed-batch mode using different substrate concentrations in the feed stream. Regarding adsorption, zeolite 3A (Z3) stood out for adsorbing all water from the gas stripping stream for the longest time period (10 h), having the highest affinity for water (0.1231 gW.gAdsorbent-1), and the lowest affinity for ethanol among the evaluated zeolites. While sago adsorbent, despite having a shorter break-up time and lower affinity for water, it was the adsorbent that did not interact with ethanol. The association of adsorption (with a fixed bed column filled with 3A zeolite) and subsequent absorption (using absorbers connected in series containing MEG) was the best combination of operations studied. This configuration provided the highest overall ethanol recovery (96.3% for hydroalcoholic solutions and 100% for extractive batch fermentation) and considerable dehydration of the gas stream (100% for hydroalcoholic solutions and 91% for extractive batch fermentations). The integrated process of fed-batch extractive fermentation and recovery by adsorption and absorption allowed the conversion of 240 g L-1 of the substrate into ethanol of 117.6 g L-1 (14.9 °GL). This value was 47% higher compared to those obtained in conventional fed-batch fermentation (operated in similar industrial conditions). The combination of the adsorption and subsequent absorption processes was an excellent strategy for dehydration of the fermentation gas stream fed with substrate concentration value similar to those found in industrial facilities (100%) and extractive fermentation with high substrate load (99.4%), and ethanol recovery in both fermentation conditions. The system was able to recover all the ethanol removed by the stripping stream. The combined process of fed-batch fermentation, gas stripping with CO2, and ethanol recovery proved to be a promising process since a greater amount of substrate can be fed into the fermentation with constant ethanol removal, directly influencing the increase in ethanol productivity. Furthermore, the combination of adsorption and absorption processes promoted the recovery of all ethanol, which directly impacts on the global increases in industrial production capacity.

Maize-legume intercropping is an alternative to improve N and P availability in soil/plant system. However, it is necessary to understand nutrients dynamics in soil and its uptake by plants in the intercropping system to optimize the process in organic systems during the same crop year. This work aimed to evaluate effect of intercropping with maize and two species of legume Crotalaria spectabilis Rhot. and Pegeon pea (Cajanus cajan (L.) Millsp.) on soil P and N dynamics, and the relation with the nutrients accumulation in plants and corn grain yield, during the same crop year, in an organic system. The experiment was a factorial design with four levels of intercropping: maize-Crotalaria spectabilis (MC); maize-Pigeon pea (MG); Maize-Crotalaria spectabilis-Pigeon pea (MCG) and maize monocropping (M) and two levels of fertilization: without fertilizer (A) and fertilization using an organic compound (P), with four replications. It measured maize agronomic characteristics like height, dry leaf matter, nutrient accumulation, dry matter of 100 grains, and grain yield. For legumes, it was estimated dry leaf matter and nutrient accumulation. Also, it measured soil NH4- and NO3- concentration, beyond P concentration, pH and the acid and alkaline phosphatases activity in the soil. Maize-Crotalaria spectabilis-Pigeon pea intercropping improved maize N accumulation when compared to Maize intercropping with Pigeon pea. Fertilization using organic manure elevated the NO3- and acid phosphatase activity on soil. Maize-legume intercropping did not affect maize growth neither corn yield. Pigeon pea in an intercropped with maize did not increase P availability to the maize as well did not altered acid and alkaline phosphatases in the soil or soil pH. The maize intercropping with with C. spectabilis and Pegeon pea does not affect plant development, it increases the leaf N content of maize, without effects on grain yield.

The present work aims to analyze the context of being a teacher and inquirer of one's own practices in the scope of mathematics education in elementary school, which presumes to find conceptions formed by experiences of knowledge that are generally constituted of skills and competences through a continuous educational formation. The descriptive qualitative research seeks to contextualize reflections on forms of interdisciplinary representations between art, that is, the "analog and digital temperament" and mathematics, comprising fractions in forms of sequences and applications, aimed at the teaching-learning process, in the ludic context of fractions and music, tied by challenges in diverse environments and moments of a before, during, and the delicate progressive return to physical school spaces, due to the pandemic unfolding of Covid-19. Thus, this work emerges from the essence of the theoretical referential of youth and adult education pronounced by FREIRE (1970, 1991, 1993, 1997), having music as the generating element of the reflections of the research scope. Together with the students, dynamics occur followed by planned evaluative activities that make it possible to work, firstly, numbers and decimal fractions, exact square roots, functions, incomplete trinomials as bold contextualized and applied interventions related to the proposed interdisciplinarity. In the path paved by the theoretical reference, relations are established with the ideas proposed by Cury (2008), a support of "error analysis" hypothetically during the study that followed students in continuity from 6th to 8th grade in the city of Vinhedo, two 8th grades and one 9th grade, as a form of adjustment, acceleration, content correction and curriculum of students from a Municipal school of Monte Mor. Furthermore, interpersonal pedagogical relationships and the virtual pedagogical dynamics were compared to the third face-to-face bias of applying the dynamics based on the scope of fractions and (in) music in 2022. Age issues in school years, behavioral issues, gaps and mismatches, (dis)organization of actions as well as hidden curricula of an elementary mathematics baggage, are some of the variables manifested in the empirical forms of belief segments that occurred in both agents of predominant performances: educator and students.

Violence against women is a universal phenomenon that affects groups of women of different origins, education, races and other social markers that interact and intersect. The phenomenon presents itself in different ways and according to Brazilian law it can be classified into five types of violence: physical, moral, psychological, property and sexual. Furthermore, violence against women is also gender-based violence, as it highlights inequalities in the treatment between men and women. These inequalities are often naturalized and create more suffering for women victims when they are subjected to these invalidating contexts. This is a topic of great importance for health care and promotion, given that this violence affects a large part of the population and generates individual and collective losses. Among the mechanisms for coping and preventing this type of violence, we can mention the training of professionals. The objective of this work was to develop, apply and evaluate the feasibility of a psychosocial training course for professionals and students from small and medium-sized cities in the interior of São Paulo. This is a mixed design study with a single intervention group and pre- and post-test assessments. The selection of participants was carried out through publicity on partner services and social networks. The training was applied in six meetings with fortnightly online intervals using focal discussions on pre-determined topics based on a literature review study. Five instruments were used: (1) Sociodemographic Questionnaire; (2) Married Life Beliefs Scale (ECVC, 2008); (3) VIRGINIA – Vignettes on gender violence; (4) Meeting Evaluation Sheets and (5) Meeting Review Activities. Data on participants' perception of gender-based violence were collected through instruments 2 and 3. Feasibility analysis was carried out considering criteria extracted from Durgante and Dell'Aglio (2018) which were used as a reference for the construction of instruments 4 and 5 The qualitative data were analyzed according to the thematic analysis proposed by Bardin (1970). The intervention group consisted of 12 participants, named here P1-P12. Participant retention was 76.5%. The sample was considered homogeneous, mostly white, female and with higher education, which made comparative analyzes difficult. Regarding the effect of the intervention on the perception of gender-based violence, the data showed no significant differences between the pre- and post-test. However, there was greater variability in responses regarding actions taken and case referrals after the intervention, in addition to a lower rate of doubts tracked by the VIRGINIA instrument. The course presented high scores in evaluations made by participants for all categories tracked by the training evaluation instruments. The use of case studies and the course content were considered positive highlights of the training. It was considered that based on the criteria adopted, the training could be considered viable. It is thought that with the appropriate changes the course could be applied again and subjected to effectiveness evaluation

This work analyzed the perceptions about the external evaluation of the Literacy Assessment Program (Proalfa) of teachers who teach for the 3rd year of elementary school at a state school in the city of Viçosa/MG. We tried to understand the following aspects of this policy in the context of practice: its legal contributions, the Simave evaluation instruments, and its consolidation in the state of Minas Gerais; how do teachers have access and how test data are communicated/processed at school; the way in which teachers use the results of external assessments; whether Proalfa results are used in school planning; the meanings attributed to Proalfa, given the demands established by the State Department of Education (SRE). To fulfill the objectives of this qualitative work, instruments such as semi-structured interviews and a conversation wheel were used. The articulation between the theoretical and bibliographic reference and the reports shared by the teachers led to the creation of four axes of analysis: perceptions attributed by the teachers to Proalfa; Proalfa results: uses and forms of appropriation at school; teaching improvement instruments: the case of the PIP and Systemic Assessments of Learning, and collaborative work within the scope of Proalfa. The research results indicate that Proalfa, as an educational public policy created in the neoliberal logic, affects different aspects of the school context: in the reconfiguration of school practices, with the training of students for external assessments, aiming at good numerical results; in the curricular narrowing, caused by the misunderstanding between the reference matrix and the curricular matrix; in continuing education, realizing that the discussions about the difficulties in the use and critical appropriation of the evaluation results are shallow and not very reflective; in the teaching improvement instruments, whose focus is to meet the policy needs and not the students' learning difficulties; in the increase of teaching work, causing an overload in their attributions to meet the demands of the SRE.

One of the natural goods that is born and cuts through the city of Fernandópolis/SP is the Ribeirão Santa Rita, which, despite starting in this municipality, only ends when it flows to the waters of Rio Grande that divides the states of São Paulo and Minas Gerais. Thus, based on science and technology that is present in the daily of the whole society, this present work aims to investigate how a regional theme (Ribeirão Santa Rita) can contribute to promote the Scientific and Technological Literacy of high school students, through a didactic sequence. Thus, through dissemination on social networks, students went invited to participate in the "Workshop on Science and citizenship: Ribeirão Santa Rita", that happened remotely. This workshop was structured using an interdisciplinary didactic sequence based on the three pedagogical moments. It was evaluated about the Scientific and Technological Literacy of the students, using the Discursive Textual Analysis, so that the corpus selected for the analysis was categorized according to historical context of the city, relationship with everyday life, health and environment, business interests and theoretical concepts. Subsequently, it was evaluated each of these categories according to the criteria of ACT proposed for Bocheco (2011). In this way, it was possible to verify that the workshop contributed to the Pratical, Civic and Professional or Economical Scientific Literacy of the students. The category where Bocheco's (2011) indicator were less evident was: "historical context of the city", while in the "health and environment" category, the Civic Scientific Literacy indicator showed great evidence.
Obtenção e aplicação de fotoanodos baseados em TiO2 com adição de nitretos de carbono polimérico do tipo poli(heptazina imida)

In this work, poly(heptazine imide) carbon nitrides containing metals single atom in the ionic form were evaluated alone and in the combination with TiO2. Initially, a percentage of 2.5% of the nickel-containing material (Ni-PHI) was added to a commercial TiO2 paste and applied to methanol oxidation under solar-simulated radiation and UV light. On a 30-layer film and under UV radiation, the TiO2-Ni-PHI sample obtained a photocurrent response of 11 mA cm-2. The performance improvement with Ni-PHI is probably due to the formation of a heterojunction between TiO2 and PHI, while nickel sites act through a cocatalysis process. In situ measurements allowed to infer that methanol was selectively oxidized to formaldehyde in the dark, and formic acid and CO2 under light. When coating Ni-PHI with a polymer of intrinsic microporosity (PIM-1) there was an intensification of the photocurrent by mechanical stabilization and subsequent re-oxidation of photogenerated H2 in the system. The behavior of Co-PHI, Co-Ni-PHI, and K-PHI was also evaluated, and it was possible to observe that the samples containing transition metals had the potential to be applied both in reduction and oxidation reactions, due to the ease of nox change of the cations used, but the highest photocurrent was obtained by K-PHI, the most conductive and organized sample. In the screening of different percentages of K-PHI to TiO2, it was found that high percentages (above 5%) created charge recombination sites, reducing the performance of the photoanode. The 5% TiO2-K-PHI film had promising results in the oxidation of paraoxon (POX) and its derivative p-nitrophenol (p-NP), where the removal rates of these pollutants increased significantly with the addition of H2O2, and consequently ROS generation, which preferentially favors indirect degradation processes, reaching removal rates of more than 80%. All these results indicate that the photoanodes obtained prove to be interesting alternatives for use in energy generation devices, as well as for chemical detoxification.

Forest degradation is characterized by the loss of biomass production, resilience, and resistance of the ecosystem. The level of degradation of these ecosystems varies greatly between degraded areas, generating a great variability in environmental conditions, which compromises the predictability regarding the survival and growth speed of plants reintroduced in forest restoration projects. Several plant species have a wide geographic distribution and can occur in places with different environmental conditions above and below the ground. The morphological and physiological characteristics of plants, which are related to resource use and conservation, may vary with different abiotic conditions and resource availability. This study experimentally evaluated the effect of soil fertility and light availability under nursery and field conditions on the allocation of biomass between aerial parts (leaves and branches), root parts (thick and thin roots) and six functional characteristics of plants: leaf area, specific leaf area, leaf dry matter content, leaf thickness, root mass fraction and relative growth rate, after the first four months of planting. We selected four tree species commonly used in forest restoration, namely Colubrina glandulosa Perkins (Rhamnaceae), Hymenaea courbaril L. (Fabaceae), Myroxylon peruiferum L. f. e Pterogyne nitens Tul. (as três, Fabaceae). In the nursery, we evaluated the effect of fertilization at three levels: the addition of low or high amounts of mineral nutrients (NPK), composed of nitrogen (N), phosphorus (P) and potassium (K), and the addition of organic matter to the soil. All fertilization treatments were carried out in full sun and in 75% shading conditions to evaluate the effect of light in conjunction with the effect of fertilization. We also evaluated the response of these plants when introduced in the field, in a deforested area adjacent to a fragment of remaining riparian forest, but with high fertility. The addition of NPK mineral fertilizer in the soil of the bags resulted in higher values of P and K, but not of N, the addition of organic matter resulted in higher values of cation exchange capacity, saturation of pH and N bases in the soil. In all species, plants reached higher biomass in the nursery under high light intensity (full sun) and lower biomass in the field. In general, plants tended to allocate more biomass to leaves and less to fine roots when grown in full sun. The functional characteristics of the plants of the four species responded similarly to different conditions of light, nutrient availability and the field. Light availability strongly influenced the functional attributes of all species, with plants grown in shade showing higher values of specific leaf area and lower values of leaf dry matter content and leaf thickness, thus producing softer and thinner leaves. In the field, plants tended to produce smaller leaves, which may have been a response to water stress. Our results showed that within the same species, plants are able to adjust to low light conditions, forming leaves that are more efficient in light interception, characteristics associated 9 with a more acquisitive strategy, within the foliar economy spectrum model, and when grown in full sun, the plants tended to produce harder and thicker leaves, and therefore longer lasting, which is characteristic of more conservative strategies. The type of fertilization had a little or neglectable effect on the biomass production and the functional attributes of the plants. Plants in the field tended developing leaves with a smaller area, probably as a strategy to reduce the effects of water stress due to the long drought that occurred throughout the time of the experiment. This study demonstrated that all species are quite plastic and that they responded similarly to the availability of light and water, but that the variation in functional attributes in response to environmental conditions was not enough to compensate for the extremes of water and light deficit. Therefore, the functional attributes may reflect the different conditions of resource availability above and below the ground in degraded areas, and the study of the phenotypic plasticity of plants may help to understand the trajectories of plant communities, through greater predictability of biomass production and management strategies in forest restoration projects.

Starting from the discomfort of many involved in the videogame market with the new monetization practices present in the emergence of the free-to-play model, I investigate this business model and propose an approach to identify coercive or manipulative potential in digital games directly from the game as a technological artifact. This is a different perspective from previous approaches (mainly game design dark patterns), which speculated about the original intention of the designer, in some cases leading to wrong conclusions, and which erroneously pointed to some game patterns intrinsic to the free-to-play model as naturally coercive. An approach based on the analysis of the artifact and not on speculation about the developer's intention is especially relevant, because in the context of imitation, a common market practice, a design with manipulative or coercive potential can be implemented without proper awareness of its operation, leading to a dissonance between original and derived intentionality. Applying the proposed approach in case studies, and focusing on F2P games for mobile devices, it was possible to identify several design elements with manipulative or coercive potential at all stages of the “Acquisition – Retention – Conversion” process. However, this does not necessarily mean that all free-to-play games use coercive or manipulative strategies, since two games can implement the same design pattern, where one of them has coercive or manipulative potential and the other does not, showing in practice that the coercive potential is in the contextualization layer, through design cues, not in design patterns, as much of the bibliography suggests. With the proposed approach, designers can investigate their own designs in search of elements with coercive or manipulative potential, breaking the cycle of imitation and allowing a reflection on game making and its implications for the society

In the context of healthcare, communication skills are considered a fundamental aspect to ensure quality in care procedures and services. Although there are studies proposing strategies and protocols aimed at qualifying the process of communicating difficult news, evidence seen in literature indicates that there are inadequacies in the formation of this skill set in healthcare courses. This study aims to understand the process of communicating difficult news from the perspective of final year undergraduate Occupational Therapy students. This is a cross-sectional, exploratory study, with a qualitative approach, in which the participants were UFSCar’s Occupational Therapy students enrolled in the last year of the undergraduate course. Data collection was conducted by interviewing 10 undergraduates and reviewed through the use of thematic analysis. The interviewed students stated that the lack of focus on the subject of communicating difficult news left them unprepared at the time of graduation, a matter associated with the non-recognition of this content in subjects that make up the curriculum, or that the subject is offered in too punctual situations during the course. Participants indicated feeling uncomfortable and unprepared for potentially dealing with the need of communicating bad news in the future, as professionals. Although they claim lack of knowledge about any protocols for communicating bad/difficult news, they claim that as a very important strategy in such dialogues, are some aspects which are in line with the recommendations that support good communication practices. In conclusion, faults were identified in the formative process/curriculum of the healthcare industry professionals with regards to communicating difficult news, requiring greater investment in the development of such skills, as this directly relates to the quality of healthcare and assistance.

In this thesis we discuss some topics about twisted K-theory calculations and equivalences between a couple of differential extension models. We start with a mathematical review of models for twisted K-theory, differential extensions for the untwisted case, and Serre spectral sequences, in order to provide an explicit link between the differential extension of the untwisted and twisted cases, in addition to giving tools for the subsequent exploration of the twists that will be used. In the first part of this thesis we determine a formula up to group extensions for the twisted K-theory for a fiber bundle over the circle S^1 with fiber a compact manifold with respect to certain twists constructed from elements of the second cohomology group of the fiber. Later this case is generalized by allowing the base to be the classifying space of a finitely generated free group and the twisting will be given by a derivation of line bundles associated to the group and the fiber. This is accompanied by examples and we finally develop a spectral sequence where the previous formulas are framed. In the second part of the thesis, a topological equivalence is developed for the Freed-Lott and Carey-Mickelsson-Wang differential extension models. Additionally, we indicate a way to achieve the differential equivalence.

The right to access education is of undeniable importance, but there is a significant gap between the guaranteed right and its effective access. Society has historically been mobilized through the formulation and implementation of educational policies, in order to reduce the effects of inequalities, respecting differences. The proposed research intended to carry out an ethnography in an Indigenous State School in São Paulo, with marked differences and inequalities, scarce educational resources and visible difficulties. Because it is not only an indigenous community, but also a needy community, located on the outskirts of the city, as urbanization approaches more and more, causing the inhabitants to experience a high and forced degree of urban interaction. However, with the advent of the pandemic, the work proposal changed, acquiring a strictly documentary character, focused on data collection and the elaboration of a bibliographic work methodology, involving critical interlocutors, seeking a dense description of the environment and its interactions, showing the peculiarities of the relationships between those involved, the guaranteed rights, the resources effectively made available and their curricular practices, since the documentary research carried out pointed out the ways and identified at least one possible divergence between the consulted norms, comparing the constitutional right to the proper processes of learning and use of the indigenous mother tongue with the curricula established by the state government.

Cancer is the attribution given to the uncontrolled growth and proliferation of abnormal cells capable of invading and destroying the adjacent tissue. According to the World Health Organization (WHO), the global growth in cancer cases will reach the 60% mark by 2040, totaling around 37 million cases. In Brazil, estimates released by the National Cancer Institute (INCA) project that approximately 66 thousand new individuals will be affected by prostate cancer (PC) in 2022. In the case of the metastatic and hormone-refractory type (mHRPC), the cells are not responsive to conventional treatment. In order to circumvent this situation, the use of cytotoxic therapies targeting microtubules (MTs) is a well-established option in clinical practice. MTs are structural elements constituted by the dimeric protein tubulin, which performs cellular functions through its intrinsic capacity for dynamic instability: polymerization and depolymerization. Changes in this dynamic lead to blockage of mitosis and cell migration, directing the cell to apoptosis. This behavior can be induced by the use of modulating agents in known sites of tubulin, configuring a promising conduct when it comes to the development of antitumor drugs. In this context, the union of pharmacophoric groups to generate hybrid molecules emerges as an innovative alternative. Thus, the present work brings results regarding the in vitro screening of bioactive ligands for the treatment of mHRPC. A cell line of PC (DU-145) and three non-tumor ones [human (HFF-1) and murine (FC3H) fibroblasts, and human prostate epithelial cells (RWPE-1)] were submitted to cell viability assays to evaluate the potency of 10 quinazoline-chalcone hybrids (AQCs) from their IC50 and CC50 values. For the selected samples, these values were used to determine the selectivity index (SI). Three hybrids (AQC-02, AQC-04 and AQC-08) were active in the PC cell line (IC50 ≤ 20 µM) and selective against non-tumor ones (SI ≥ 5), and therefore referred to cellular assays involving analysis of characteristics observed in the metastatic cascade. The 3 hybrids inhibited migration in qualitative wound healing assays at single concentration (≥ 50%) and concentration x effect. Furthermore, through a transwell study based on Boyden's chamber, it was possible to quantify and confirm the inhibitory effect of hybrids on tumor cell migration and invasion (both with IC50 ≤ 10 µM). Kinetic assays directed to the molecular target corroborated the classification of the hybrids as tubulin polymerization inhibitors, as well as made it possible to determine their IC50 values (5.71 ± 0.09; 9.04 ± 0.40 and 8.40 ± 0.31 µM, respectively). Competition assays suggested that the hybrids possibly interact with tubulin near or at the colchicine site itself. Additionally, fluorescence assays reinforced the action of the compounds in destabilizing cell division and promoting the nuclear fragmentation of DU-145. This work, therefore, shows promising results that, in consonance, support the identification of lead compounds eligible for in vitro and in vivo ADME (Absorption, Distribution, Metabolism and Excretion) assays, aiming at the selection of candidates for new drugs for the mHRPC chemotherapy.

Titanium alloys have got features that classify them as excellent candidates for medical applications. However, they have porr machinability mainly due to their low thermal conductivity, high chemical affinity to almost every tool material and their small modulus of elasticity. Regarding commercial milling tools, inserts usually differ one to another in terms of grade (such as substrate and coating composition and microstructure) and geometric characteristics (nose radius, rake angle and chipbreaker shape), so that it is difficult to find two products differentiated by one single variable. Due to these factors, the general goal of this research is to investigate the correlation between tool nose radius and the roughness after milling of Ti-6Al-4V ELI titanium alloy. For that, it was necessary to grind carbide inserts to prepare the three different nose radii (re = 0.8 mm; 1.2 mm or 1.6 mm) as well as their characterization, besides designing, manufacturing and evaluating a customized tool holder with a single insert seat. Tools once prepared were tested through face milling experiments, keeping fixed cutting speed (vc) at 60 m/min, axial depth of cut (ap) at 1 mm, in addition to radial depth of cut (ae) at 16.8 mm and flood coolant. Five diferente levels were used for feed per tooth ( fz): 0.10 mm; 0.15 mm; 0.20 mm; 0.25 mm or 0.30 mm. After the experiments, the specimens were evaluated in terms of different roughness parameters, and all data were statistically analyzed by means of analysis of variance (ANOVA). Regarding the characterization of the ground inserts, there was no significant variation in the irregularity of the edges as a function of the different nose radii. The design of the tool holder proved out to be adequate to the operation, providing a high design safety factor. Regarding the surface integrity of the machined surfaces, results show that, in exception of one tested condition, all other values of Ra satisfy N6 roughness grade. The pass associated to re = 0.8 mm and fz = 0.15 mm probably provided higher vibrations. ANOVA indicates that, in statistical terms, only feed ( f ) and the interaction between feed and nose radius ( f x re) affect the roughness parameters Ra, Rq, Rt, Rz, and Rmax, although these effects are not obvious. There was no statistically significant difference for skewness (Rsk), which tends to zero and, therefore, expresses an approximately symmetrical surface in terms of peaks and valleys. The same for kurtosis (Rku), which remained close to three, which means a distribution close to normal.

CO2 is a greenhouse gas whose production has intensified in recent decades, generating its accumulation in the Earth’s atmosphere. Thereby, numerous negative environmental changes, such as the aggravation of the greenhouse effect, have occurred all over the planet. Mitigating approaches have been adopted in several countries around the world, such as the capture and storage of CO2 and the use of renewable energy sources instead of fossil sources. Furthermore, the use of this gas as a carbonaceous input for the production of chemical compounds with high added value is a promising alternative. In this regard, the catalytic hydrogenation of CO2 is a carbon recycling technology that has been explored in recent years. This reaction can occur via electro-catalysis and heterogeneous catalysis at gas-phase. In the present work only the catalytic process at gas-phase will be focused. In this process H2 is used as a hydrogen source and the application of Cu-based catalysts promotes mainly the formation of C1 compounds, such as CO and methanol. These reactions typically occur at temperatures of 200 – 300 °C and under pressures of 2 – 7 MPa. Thus, the investigation of more favorable conditions for the hydrogenation of CO2 at gas-phase on non-noble metals-based materials, such as copper, for the efficient and selective production of high energy density compounds, such as ethanol, ethylene, propane and butanol, is necessary. Recently, in our research group, catalytic studies of CO2 hydrogenation on copper, conducted at gas-phase in the presence of water steam under atmospheric pressure, led to the formation of ethanol. There are evidences that water acts in the stabilization of adsorbed intermediates of the reaction, such as CO, favoring the formation of ethanol. However, the impact of the catalyst properties in this reaction has been poorly explored. In this context, the objective of this work is to study the influence of the copper oxidation state on the CO2 hydrogenation reaction at gas phase in the presence and absence of water steam on Cu materials, aiming at the production of alcohols with two or more carbon atoms (C2+OH). Results of this work showed that ethanol production is more pronounced when we used water steam as a hydrogen source and catalysts with a mixture of oxidized and metallic copper species. Furthermore, it was observed that the presence of oxidized copper species together with metallic copper species was important to improve the productivity of methanol, in addition to ethanol, when H2 was applied as a hydrogen source, indicating the importance of having different copper species to intensify the production of alcohols.

The purpose of the present study is to promote English teaching as a second language for children from an anti-racist perspective. For that, we share a unit of the courseware "My Wild Hair", supported by a bibliographic-propositional research, of a qualitative nature, having as target audience students in the early years of Elementary School. With and through the proposal, it is intended to build together with the students a valued self-image, providing opportunities for them to recognize themselves as part of their ethnic-racial groups as well as to become aware of the institutional racism and how it dictates and organizes Brazilian society. The teaching strategies of the courseware cover the increment of games in the classroom, exploring the potential of different digital platforms and taking advantage of the motivational content they afford. Here, students are invited to explore the fictional world of Sangoma, from the game “My Wild Hair”, overcoming each linguistic obstacle and developing criticality as well as self-esteem regarding the raised themes. The material is, above all, a reminder about how beauty lies in diversity.

This research aimed to analyze the perspectives of professionals involved in the care of individuals with intellectual disabilities who are aging, focusing on their understanding of this life stage and established conceptions regarding disability, aging, and their own role in activities of daily living. The main objective was to investigate the understanding of professionals working with individuals with intellectual disabilities aged forty (40) and above, regarding functionality in this stage of life, as well as their perceptions of aging and disability. Specific objectives included: (a) analyzing the functioning of institutions catering to individuals with disabilities in this life stage; (b) exploring how independence in daily life tasks is perceived by these professionals; and (c) examining the role of these professionals in the care of this population. Nine professionals working in special education institutions - referred to as Institution A and B - where adults with intellectual disabilities aged forty (40) and above are located, participated in this research. The professionals included caregivers and healthcare professionals such as physiotherapists, occupational therapists, and gerontologists. Data collection involved semi-structured interviews, and the results were analyzed and categorized into four main themes: (a) Concept of Disability; (b) Aging and Disability; (c) Disability, Aging, and Independent Living; and (d) Professional Roles. These findings were then discussed in line with existing literature in the field. The data gathered indicated that professionals observed signs of premature aging among individuals with intellectual disabilities in both institutions. There were still stigmas regarding the understanding of the concept of "disability" among some interviewed professionals, which could hinder the development of activities aimed at promoting independence due to a perception of dependence. Additionally, the lack of specific training in working with individuals with intellectual disabilities among these professionals was evident, highlighting another factor contributing to the absence of quality care.
