The growing incentive and awareness regarding the consumption and use of more sustainable proposals, biocolorants from filamentous fungi are presented as a promising alternative to synthetic colorants. These biocompounds are less harmful to living beings and the environment, presenting greater stability and biotechnological potential compared to other natural sources. In this context, this thesis aimed to characterize the red biocolorant synthesized by the endophytic fungus Talaromyces minnesotensis, as well as to evaluate the biocolorant production process in shaken flasks and in conventional bioreactors, aiming the improvement of the bioprocess. Initially, the endophytic fungus T. minnesotensis was phenotypically characterized by assays carried out in different solid media. Then, its potential for biocolorant production was verified through submerged cultures in shaken flasks. The synthesized biocolorant was characterized by means of fluorescence, cytotoxicity (MTT and MIC), stability, and applicability assays. The characterization and application tests showed that the biocolorant has activity against human hepatoblastoma cells (HepG2) at concentrations above 5.0 g L-1, while for pathogenic bacteria and yeasts the concentration must be higher than 50.0 g L-1. In addition, the bioproduct showed high stability at neutral pH values (6 to 8) and at low temperatures (10 to 20°C). Expressive coloring potential of the red biocolorant produced in different matrices such as detergent, gelatin, enamel, paint, and fabrics, was also verified, which indicates the feasibility of a more in-depth study of the bioprocess to improve and increase its production. Thus, a factorial design (22 +3PC) was performed, aiming to evaluate the influence of three combinations of impellers of different geometries under different conditions of agitation frequency (400-800 rpm) and specific air supply flow rate (0, 5-1.5 vvm) on the production of biocolorant in a conventional bioreactor. The results were analyzed based on the Global Desirability (DG) in terms of the main response variables of performance, production, and productivity of biocolorant. It was shown that the configuration composed of two elephant ear impellers (EEDP-EEUP) operated at 600 rpm and 1.0 vvm was the most favorable to the bioprocess, obtaining a production of 45.30 AU. By correlations assessment, it was verified that the hydrodynamic properties tended to present greater relevance to the performance of the bioprocess compared to the oxygen transfer properties. In order to evaluate the performance of the bioprocess on a larger scale, an exploratory study was carried out to scale up the bioprocess from 4 to 10 L bioreactor, in which a satisfactory result was obtained by reaching an equal production for both scales. Finally, in order to improve the production of biocolorant, the use of the fed-batch mode in shaken flasks and in a conventional bioreactor was evaluated. The production in these assays reached expressive results for both scales: a maximum production of the order of 86.0 AU in shaken flasks, and maximum production ranged from 80 to 238% in relation to the conventional batch for bioreactors. Regarding this last, the increase of production depended on the feeding conditions (FCSF), reaching a maximum production of approximately 153.0 AU in the most favorable condition at a feeding flow rate of 0.01 L h-1 (F) and a substrate concentration of 60 gS L-1 (CSF). These results proved the fact the bioprocess production of colorant by the endophytic fungus T. minnesotensis has a high potential for future studies aiming for its implementation at pilot and industrial scales.

Given the potential that big data can bring to organizations with the use of the large amount of unstructured data generated quickly in different formats and sources, and the scarcity of empirical research to validate its impacts and opportunities for performance measurement systems (SMD). The main objective of this thesis was to develop an SMD prototype using deep learning and big data analytics (BDA) techniques for collecting, storing and analyzing unstructured data. Among the different formats of unstructured data, video images were used, due to their great availability. As a way to present the cognitive process of the design and construction of the SMD prototype in a functional state and thus create generalizable knowledge for this class of problem, the design science research (DSR) research method was used. During the prototype development process, it was possible to identify convergences between the MDS development phases and the phases to be followed to put a big data project into operation. The analysis of these convergences together with the learning acquired in the prototype development process, highlighted the most relevant points in this type of project. The research results indicated the importance of a support infrastructure for the use of unstructured data by the SMD and the even greater dependence on the area of information technology and computer science. The results also showed that, by providing the creation of performance measures and advanced analysis of unstructured data, previously unfeasible, BDA, deep learning and computer vision techniques positively influence the validity, reliability and timeliness of this resource, as well as its level. aggregation and costs. Thus, the main contribution of the thesis was to generate relevant, practical and prescriptive knowledge for the use of unstructured data from videos in SMDs, in order to contribute to their improvement and adaptation.

With the effervescence of social movements, the understanding that a language is also a place where the identity of a collectivity is anchored has made it also an object of struggle. With the advent and intensification of the use of the internet, and markedly of online social networks, new forms of organization of socially underprivileged groups (indigenous community, women, blacks, LGBTQIAPN+, and people with disabilities, for example) have become more evident. Regarding the use of gender-neutral as a form of recognition and representation of the LGBTQIAPN+ community in social spaces, including the language itself, it was found that there is linguistic dissidence - a concept proposed in this dissertation - as a possibility of subversion, in this case, of the linguistic system. As a consequence, several linguists and popular linguists have also positioned themselves in a plural and diverse way about the discursive procedures that act in the relationship or not between the grammatical category of gender and gender identities. The analyzed texts were written by professional linguists (scientific knowledge) and by non-linguists (popular knowledge) starting from the hypothesis, which was approached and proven, that it is in the continuum between the scientific and the popular that there are disagreements and agreements, both concerning the validation of the knowledge of popular linguists, as concerning the proposals raised for the (re)formulation of the linguistic aspect as a marker of gender in the Portuguese language of Brazil. To this end, we are guided by the studies developed by Folk/Popular Linguistics (ALBURY, 2017; MURILLO, 2008; PAVEAU, 2007; 2018; 2021; PRESTON, 1993; 1994), which proposes that the knowledge of non-linguists is important and must be observed and integrated into scientific studies, as well as in the proposals of Discourse Analysis (FOUCAULT, 2014).

Microalgae are photosynthetic organisms, generally fast-growing, with simple nutritional requirements and physiological plasticity. They produce biomolecules in great variety and many with high added value. Compared to the number of known species, few are commercially used and described in relation to their biochemical composition. This research aimed to investigate the physiology of microalgae with a biotechnological approach. We started the study by investigating 12 strains, including organisms from the Bacillariophyta, Cyanobacteria, and Chlorophyta groups, and a strain chosen to be subjected to biochemical manipulation. CO2 fixation was quantified to associate microalgae productivity with the reduction of important greenhouse gas. Algae were grown in a high-performance cylindrical photobioreactor (PBR) with internal lighting in batch mode under controlled conditions. As a physiological response, growth, and photosynthesis parameters (PhytoPAM), biomolecules (carbohydrates, proteins, lipids total, fatty acid composition, chlorophyll a, and carotenoids), and antioxidant potential were evaluated. We complement the study with an analysis of the biomass by Fourier transform infrared spectroscopy (FTIR) and thermogravimetry (TG). The results showed that Desmodesmus spinosus had the highest yield of algal biomass (2.4 g L-1), in addition to presenting high levels of chlorophyll a, and total carotenoids, as well as Monoraphidium indicum. As for the fatty acid composition, Nannochloropsis gaditana stood out in the production of eicosapentaenoic acid (EPA). However, Kirchneriella aperta stood out in the parameters: antioxidant activity (69%), protein and carbohydrate content, photosynthetic rates (~0.80), and a higher rate of CO2 fixation. FTIR showed that the species with the highest lipid content were in Chlorophyta N. gaditana, K. aperta, M. indicum, Chlorolobion guanense, and Ankistrodesmus densus. TG showed 3 stages of thermal decomposition for all species. The microalgae K. aperta was selected for the study of biochemical manipulation. In it, the alga was exposed to different colors of light and copper concentration, alone and in combination. We showed that copper and isolated light colors resulted in higher concentrations of biomolecules compared to the combined factors and the control. Finally, a large-scale test (250 L) using the microalgae Chlorella fusca was carried out in a raceway reactor maintained in an oven. Developed in Spain, this study showed that real-time monitoring of photosynthesis showed rETR values twice as high compared to spot analysis performed in the laboratory. In addition, the microalgae C. fusca showed high concentrations of photoprotective compounds. The present results provide relevant information on the physiology, photosynthesis, and biochemical characterization of different microalgae and highlight potential species for further investigation with the aim of commercial applications.

This article investigates the epistemological foundations of Francis Galton's eugenics based on Max Horkheimer's Critical Theory. Grounded on a bibliographical research, we analyze the texts in which the English polymath structured the rationality of his science-religion, contrasting them with the theoretical-critical diagnosis of the crisis of reason. We conclude that Horkheimer’s argument denouncing the enlightened roots of eugenics, despite not having been explored in historiography, remains fundamental to the understanding of the eugenic scientific rationality, which we denominated eugenic reason.

Myofascial pain syndrome (MPS) is a specific clinical condition of regional muscle pain, very often associated with the presence of one or more tender points, which in these circumstances are called trigger points. Many techniques and types of multimodal treatment have been used, showing good results. This study aims to investigate the effects of Transcranial Direct Current Stimulation combined with Occupational Therapy on the primary outcome pain. Therefore, a multiple case study with an experimental approach was adopted as a method. In which the participants were referred by neurologists and previously diagnosed. Participants were screened (Hamilton Anxiety Scale and Beck Depression Inventory instruments), initial assessment (Visual Analog Pain Scale and Body Map instruments, Mc Gill Pain Questionnaire, Canadian Occupational Performance Measure, Occupational Role List and World Health Organization quality of life instrument - abbreviated), intervention (3 times a week, 30 minutes, 12 sessions) and final assessment. Participants were randomly divided into two groups, an Occupational Therapeutic Intervention (OT) group and an Occupational Therapy and Transcranial Direct Current Stimulation (tDCS+OT) group. The results show that all participants are female, most have pain in the cervical region or close to this area. It is also observed that the participants have difficulty in occupational performance in the items self-care and productivity. In the primary outcome pain in both the right and left hemibody, the target participants of the OT intervention only had better results, in the change of the pain level and also in the pain intensity. In the secondary outcome quality of life, all participants improved, but participants in the tDCS plus OT group had a better mean score when comparing pre- and post-intervention outcomes than participants in the OT only group. In the secondary outcome occupational performance, all participants improved their scores in both satisfaction and performance, but the participants who had a change in score of 2 points or more considered as clinically significant by the COPM instrument were: 1 participant in the tDCS group plus TO and 2 participants in the TO-only group. It can be concluded from the analysis of the results that both an intervention (tDCS plus OT) and another (only OT) were beneficial to their participants, but that in this scenario the OT only group had better scores in more predicted outcomes (pain and functional performance). In addition, the study could be carried out with a larger number of participants so that it is possible to generalize the results and validate the protocol built for the intervention of OT, as well as, perhaps, confirm that tDCS is an adjuvant and potentiating technique for the TO. The innovative character of the theme for the Occupational Therapy profession is highlighted, in relation to SDM and one of the interventions made - tDCS.

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.

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.
