International migrations is a subject discussed all over the world in the most diverse areas of knowledge, including Education. This research aims to understand and understand the processes of welcoming Haitian children in public preschools in the city of Sorocaba-SP, Brazil. We also seek to identify and analyze the role that interactions and games – guiding principles of Early Childhood Education, according to the National Curriculum Guidelines for Early Childhood Education (Diretrizes Curriculares Nacionais da Educação Infantil - DCNEIs) – can play in this embracement. It also intends to raise available references and deepen readings and studies on the relationship between migration and education. It also seeks, through interviews with teachers, to identify the main challenges encountered in the experiences with Haitian children, who, in addition to being migrants, are black. In addition, this academic thesis aims to analyze official documents of the Department of Education in order to draw an overview of migrant children enrolled in the public network of early childhood education in Sorocaba. We base our studies on migration on Katia Norões (2016, 2018, 2020), Abdelmalek Sayad (1998), Ethel Volfzon Kosminsky (2000), Demartini (2011, 2012, 2017). The methodology is based on qualitative research, with literature review and analysis of interviews with teachers. The survey's findings indicate that the number of Haitian children enrolled in the municipal network of Sorocaba is large and that the challenges faced by teachers are also large. Among these challenges are the lack of public policies aimed at migrant children and communication with children and their families (language).

This study investigated drying aroeira (Schinus terebinthifolius Raddi) leaves in a rotating dryer with a perforated wall to evaluate the influence of operating conditions in the preservation of color, and bioactive compounds of leaves. The fresh leaves were characterized through the measurement of dimensions, moisture content, color attributes (L*, a*, and b*), the concentration of total phenolic compounds (CFT), and antioxidant activity (AA). In drying tests performed both in a natural convection oven and in a thin-layer fixed-bed, under temperatures of 50 and 70°C and air velocities of 0.3 and 0.9 m/s, it was verified a significant influence of the air temperature on the drying rate and that internal mass transfer mechanisms control the drying process. The drying conditions in the rotating drum was evaluated through a fractional 2(4-1) experimental design. The air temperature and velocity, the charge (mass) of leaves in the drum, and the drum rotation speed were the investigated factors in this design. The results showed that the drying rate in the rotating drum was strongly dependent on the temperature and, in some conditions, it also depended on the air velocity and the charge of leaves. It was found from the ANOVA that the air temperature was the only statistically significant variable (p-value<0.1) to estimate the drying time and a*/b* ratio (which quantifies the leaf color deterioration). Experimental curves of moisture content versus time were fitted to empirical drying kinetic equations. From the tested equations, the Midilli was the one that best fit the experimental data (R²>0.9924; RMSE<0.0321 and X²<0.0010). Based on the results of the fractional design, a Central Composite Rotational Design (DCCR) was carried out to evaluate the influence of operating variables on the drying time and quality attributes. The assays were conducted under a fixed rotating speed (3 rpm), air temperature varying between 50 and 60°C, air velocity between 0.3 to 0.9m/s, and charge of leaves between 100 and 200g. A decrease in the CFT and AA and an increase in the ratio a*/b* were observed. Regression analysis showed that the temperature, air velocity, and mass of leaves were statistically significant variables for the drying time and a*/b* ratio. The statistical models showed optimal regions laying between Tar > 55°C, var > 0.6 m/s combined with m < 120g, for shorter drying times and, overall, Tar < 53°C for less deterioration. The optimization based on the desirability function indicated that the optimal condition for the shortest drying time (390 min) and the least color deterioration (-0.0782) was achieved under a temperature of 52.3°C, air velocity of 0.86 m/s and charge of leaves of 181.67g.

The rapid growth of the population, combined with socioeconomic activities, results in a continuous and intense pressure on natural resources, causing transformations in the units of a given environment. In this context, the objective of this research was to characterize the physical elements that make up the Sub-Basin of Rio Claro, located in Santa Rita do Passa Quatro, SP, seeking thematic mappings to aid in a better visualization of the space and analysis of the components, being necessary understand the influence that the area surrounding this basin exerts on the municipality. For this, the influence of hydrography, slope, soil types, hypsometry, relief forms and land use and occupation that directly affect the location were analyzed. This influence was evaluated in terms of the dynamics of the topography and also the urban expansion in the area. Finally, the analysis of the information collected indicated points that present a medium to high degree of fragility, both potential and emerging, being these places susceptible to processes of environmental impacts such as erosion, silting, degradation of APPs, among others. The need for reassessment of land use and occupation is then verified, and it is revealed that the work can support future planning and territorial management projects in the municipality.

This research aimed to analyze the written language practices developed by the researcher herself as a teacher of the group of children in the last stage of Early Childhood Education (phase 6) in 2019, in an educational unit of the municipal school system of a city in the interior of São Paulo State. The chosen methodology was the exploratory qualitative research conducted out through documentary research and the autoethnographic approach. Data analysis was carried out from the researcher teacher's pedagogical records, using her annual plan, her weekly plan and photographic records of the written language practices accomplished that year. The development of the investigation took place from a framework composed of theoretical contribution of works by reference authors in written language in Early Childhood Education in the historical-cultural perspective; a bibliographical survey of academic productions on the subject was also made in the publications of ANPEd's works, according to the State of Question methodology, and a brief interpretation of official guidance documents and what they propose for the teaching of written language in early childhood education which, as well as the theoretical reference, contributed to the dialogue with the analysis of the pedagogical documents. From this analysis, we sought to understand how the researcher teacher conducted these practices, considering the children's specificities and the playful dimension in this work. The study pointed out that the researcher teacher performed several practices involving mostly written language, with games and a playful dimension, besides the social use of writing, which is in line with what is recommended by the historical-cultural approach. In addition to these, activities of a mechanical nature were identified, such as outlining the dotted lines of letters and copies of words, since writing was approached out of context and meaning for the children. The analysis of these practices supported by theoretical contributions enabled a reflective process, leading the researcher teacher to a process of reframing her work. It was identified, therefore, that this study caused changes in conceptions and actions based on the reflection of its own practice. As a result, the research reaffirms and proposes the written language practices developed with children whereas the social use of writing was performed in an interactive way, with playful aspects and interactions, in line with what the historical-cultural approach advocates. This result will be shared as a product with Early Childhood Education teachers, enabling a reflective process on written language practices among peers.

This thesis sociologically explores the continuities and ruptures of research on homosexuality and aging from 1970 to 2018. Specifically, it inquiries how the biogerontological sciences have represented homosexuality under the analytical perspective “inclusion-difference”. This prism, called the “inclusion-difference paradigm”, was crystallized mainly in the 1990s in research policies involving funding, recruitment and selection of populations for experimental and randomized studies in the United States. That is, when the so-called “special groups” were included in clinical research funded by the National Institute of Health, and sociological categories were reincorporated into the studies in the form of both political and epidemiological imperatives. The results attest, first, that the representations of homosexuality in (bio)gerontology were split by the sexual panic caused by the HIV/AIDS epidemic in the 1980s and 1990s. Secondly, they allow us to visualize how the discourse for “inclusion” was constituted in association with “difference”, not necessarily providing a more positive vocabulary to people socially demarcated as part of “special groups”. In this context, this study also examined the centrality acquired by the language of pathology during the deadliest period of the HIV-AIDS epidemic – 1981 to 2000 –, confirming not only its descriptive but normative configurations. The language of pathology formed during AIDS epidemic, as evidenced by the data, was closely linked to moralizing discourses, even after the commercial availability of Highly Active Antiretroviral Therapy (HAART), in 1996. While “high risk”, “gay men”, “MSM”, “person with AIDS” and “anal” syncretized and responded to the already known frameworks of gender and sexuality produced by the biomedical sciences, other processes of stigmatization followed a historically unknown trend in biogerontology. As part of the research developed at Harvard University, in the United States, and in the analysis of the AIDS’ Obituaries section – from more than five thousand death records collected from the editions of the Bay Area Reporter, from 1982 to 2000 –, the study produced original information that allowed us to know how deaths also increased an epidemiological vocabulary that conceived a “mortality prophylaxis” based on racializing descriptions. In methodological terms, the research was based on qualitative and quantitative documentary analysis, carried out in the Web of Science database and in collections on sexuality, history of science and AIDS from the Arthur and Elizabeth Schlesinger library, from the Radcliffe Institute for Advanced Study, and from the New York Public Library. Empirical evidence shows that there was a kind of “categorical alignment” in relation to biomedical definitions of homosexuality and aging in the context of the inclusion of so-called “special groups” in the 1990s; and the consolidation of a change in the language of pathology since the spread of HIV-AIDS.

Introduction. Reflections on science, technology, and society in the school context collaborate to construct the theoretical assumptions. At the same time, they value students' interdisciplinary education, encouraging them to expand, understand, and think about the positive impacts of science and technology in society, as well as to question themselves and take a stand when facing science's inaccuracies and mistakes. On the other hand, scientific literacy, beyond discoursing on science education for all, especially for the students, expatiates on the characteristics of individuals which are considered scientifically literate, dividing them for knowledge levels. The scientific initiation's (IC, in Portuguese) activities, as a curricular component, an institutional program, or part of public education policy, have been shown an essential complement to the improvement and development of technique, scientific and social abilities of the professional and technological education students from the secondary school (EPTNM). Problem. The Instituto Federal de Educação, Ciência e Tecnologia de São Paulo (IFSP) follows national guidelines but has autonomy for developing IC's related activities. IFSP campus Campinas (IFSP/CMP), specifically, has students and teachers significantly engaged in IC practices. However, these activities have not yet been described and analyzed in the literature. It is understood that a study on the CI process of this institution, from the perspective of scientific literacy theoretical principles, as well as specific public policies, can contribute to the understanding of the construction and experimentation of scientific knowledge in professional technological education. Objective. To investigate and understand the formative contributions of the IC to the students of the EPTNM of the IFSP/CMP and to analyze the research activities regarding the production and dissemination of scientific knowledge through the projects of scientific initiation developed by these students. Methodology. The paper is a case study of the IC program developed at IFSP Campinas. It is characterized as an exploratory and descriptive study, as it goes further in understanding the addressed subject at the same time that it aims to characterize a specific reality, synthesizing the research subjects' outlook. The bibliographical research sources were the Portal de Periódicos da Capes, the SciELO database, and the IBICT's dissertation and thesis database. In the documental analysis were consulted books of the physical libraries of Unicamp and IFSP. For gathering data, a questionnaire was applied to the students who participated in IC in 2019. For the data analysis, it was used the content analysis. Results. The IC program contributes to the critic and scientific training of its participants. Besides that, evidence of science, technology, and society and scientific literacy was found in the analyzed institutional research programs – demonstrating balance in the occurrence of the types of literacy levels addressed. It was also possible to observe the presence of scientific literacy in the speech of the students that answered the questionnaire, in which the most recurrent was the functional scientific literacy.

Landscapes with water bodies present ecological elements and processes that guarantee environmental quality and quality of life for the living beings that inhabit or frequent them. Anthropogenic interventions in these watercourses made throughout history, as exemplified by the construction of dams for different purposes, can bring both negative and positive impacts and, therefore, configure themselves as typical 'complex environmental problems'. Such is the case of “UFSCar Lake”, a symbol reservoir of the Federal University of São Carlos (UFSCar – São Carlos campus) formed by the damming of Monjolinho river, but which had to be drained in 2019 due to safety problems in its dam. Since then, alternatives for the water body have been studied, as in addition to the cost of renovating the dam being very high, the management related to it has also become very complex due to current legislation. Because of this, the alternative of renaturalizing Monjolinho river in São Carlos campus of UFSCar has been considered as an adequate solution to this problem. Therefore, this study aims to analyze the challenges, advantages and disadvantages associated with the possible renaturalization of UFSCar Lake in relation to ecosystem services, environmental impacts, safety and economic costs. Therefore, a bibliographical survey of the history of UFSCar Lake was carried out; and technicians, researchers and managers who are specialists in the topics covered in the work and/or were involved in the lake's drainage process were interviewed. The results obtained by crossing primary and secondary data indicated that the damming of the Monjolinho river generated negative impacts on its biota and on the quality of its water. On the other hand, the lake started to perform cultural ecosystem services and shelter a new adapted biota. However, due to the financial limitations and complexity of managing a dam due to recent legal changes, it is very costly for the university to maintain the dam. Therefore, the alternative for the renaturalization of Monjolinho river in the stretch where it crosses the UFSCar is promising, as it would not only be less costly and safer in the long term, it could reduce the environmental impacts generated by the dam as well as create a new symbol for the community. These conclusions are corroborated both by theoretical aspects and national and international examples already carried out in other rivers, as well as shared by the interviewees in this work.

It’s known that the canopy of the tree is responsible for the production and characteristics of the fruits, however the rootstock can have an influence, since the agronomic characteristics are the result of the interaction between both. Essential oils are products with high added value, due to their characteristics and bioactive molecules. They’re used in various industrial sectors. There is interest in expanding studies in this area. Therefore, the aim of this study was to determine the influence of rootstock varieties on yield and composition of the essential oil of Tahiti acid lime. Yield was evaluated in the two harvests (2017/2018) and vegetative development was evaluated in 2019. The hydrodistillation method was used for extraction of the essential oil and for quantification and identification of the components, analysis with GC-MS and GC-FID was used. As main results, the rootstock varieties that induced the greatest volume in the canopy of Tahiti IAC-5 acid lime were citrandarins H150, Rangpur lime, H121, H70, H145, H173 and H10. In the analysis of essential oils, yields per 100g of Tahiti acid lime peel ranged from 0.77 to 1.67%. Regarding the yield per hectare, citrandarin H10 induced a greater amount of oil per hectare in both crops. A total of 56 compounds were found, of which 48 showed significant differences in relative percentage. The major components were monoterpenes and monoterpenoids, such as limonene (30%), y-terpinene (11%), geranial (8.4%), β-pinene (6.5%) and neral (6.4%). Demonstrating influence of the rootstock on the composition and yield of essential oils.

Knowledge-intensive business services (KIBS) companies play an important role in knowledge generation and transfer. In addition, KIBS has supported the implementation of service-oriented business models in manufacturing companies. In this way, these companies benefit from connections with KIBS as they use these services to complement their capabilities and become more competitive. The connections between manufacturing companies and KIBS are also able to contribute to regional economic development through the generation of new jobs and new businesses. The symbiotic connections between KIBS and manufacturing companies and their effects on these companies and on the region in which they are located have been called territorial servitization. This dissertation aims to evaluate the impacts of KIBS concentration on productivity (Total Factor Productivity – TFP) of Brazilian manufacturing companies and determine the moderating role of absorptive capacity in this relationship. To achieve the objective, the research method was structured in two stages. The first was a scoping study in order to gain a better understanding of the connections between KIBS and manufacturing companies. The second stage corresponded to the development of an econometric model with variables of concentration of KIBS and productivity of manufacturing companies. The results show that only the concentration of KIBS is not capable of generating positive effects on the productivity of manufacturing companies. These companies must have sufficient absorptive capacity to transform the available knowledge into productivity gains. This dissertation contributes to the advancement of the literature on territorial servitization by providing a thematic analysis regarding the convergence of the literature between KIBS and manufacturing companies. It also points out that the benefits of territorial servitization depend, in addition to the concentration of KIBS, that manufacturing companies are able to exploit the knowledge of KIBS. Theoretical and managerial implications are presented in the dissertation.

In this work, we will study the existence of non-trivial weak solutions for two classes of elliptic and nonlinear problems, whose growth condition on these nonlinearities is subcritical and which involve general operators of the p&q-Laplacian type. The first problem will address the existence of non-trivial weak solutions for a general class of eigenvalue problems, which was studied in [9]. In the second problem we study the existence of multiple solutions for a class of equations similar to the previous one, by adding a perturbation to the nonlinearity. The tecniques was motived by the thesys [32]. The main tools in your study are variational methods, including the classic Ekeland Variational Principle and the Mountain Pass Theorem.

This dissertation aims to analyze the mediations and interactions that occur through educational animations during the teaching and learning process of natural numbers and their operations, especially regarding addition and subtraction for children enrolled in the 3rd year of Elementary School I. In this context, the format of educational animations is made from problem situations. Such mediations and interactions are directly related to the work developed in a school in São Paulo’s state, in 2020, during the COVID-19 pandemic period. 36 children aged 7 and 8 years participated. The question that led the research was defined as follows: How do interactions and mediations of students in the 3rd year of Elementary School take place in the format of educational animations in mathematics classes so that they can acquire new knowledge related to the concept of natural numbers and about addition and subtraction operations? The qualitative research is based on the theoretical and methodological assumptions of cultural-historical theory. Data was obtained based on the development of mathematical problem situations, presented in animated video format, called educational animation, which involves the conceptual nexus of natural numbers: positional value, grouping and addition and subtraction operations. The information obtained indicates that interactions and mediations occur when: 1) children have autonomy to explain their learning with the assistance of some technological supports, such as educational animations and the abacus, even in a difficult and pandemic context of COVID-19; 2) the organization of classes by the teacher leads to educational practice that considers communication, dialogue, collaboration as important aspects of pedagogical strategies to develop the teaching and learning process. In order to make these interactions and mediations take place satisfactorily, four educational videos were prepared, which are configured as educational products and potentialized this new communication that emerges, pulses, develops in favor of discovery and an engaging and innovative educational strategy with its effective inclusion in the classroom.

With the awareness and consequent increase in complaints, it is known that violence by intimate partners (IPV) is still a reality for many people, especially women, the main victims of this phenomenon. Many studies report the harmful effects caused by violence. In addition to possible physical damage, violence directly affects the way these victims act in the abusive context, for example, dealing with their emotions. The perception, use, understanding and regulation of emotions are aspects studied by the theory of emotional intelligence. Therefore, one can question the way emotional intelligence is presented in women that live in a violent context. Considering the importance and lack of studies on this topic in Brazil, the aim of this study was to investigate aspects of emotional intelligence in women who report having been victimized by any type of violence by an intimate partner, as well as in women who report having practiced some form of violence against their intimate partners. For this, in a sample of 100 women, with a mean age of 28.19 years (SD = 10.3), IPV behaviors (practiced and suffered) were verified, then were analyzed with the results of the emotional intelligence profile obtained. by different evaluation methods (performance and self-report). The instruments used were the Conflict Tactics Scale (CTS2), to verify violence in intimate partner relationships, as well as emotional intelligence assessment instruments, the Emotional Intelligence Assessment Battery - BIE (performance measurement) and the Emotional Skills Inventory - ICE 3.0 (measurement by self-report). The results suggest that there was a pattern of greater frequency and greater severity of violent attitudes practiced against women, although more participants reported having practiced IPV than suffered. As for the emotional intelligence profile, the data obtained by the BIE and by the ICE demonstrate a conformity of the sample means in relation to other studies that applied these tests in other samples. In addition, the study found that the facets related to Emotional Regulation were similarly conceptualized in self-report and performance tests, contradicting studies in the field that demonstrate different results between the performance EI test format and the self-report format. The data found also indicate an important negative association of EI skills, specifically those related to Emotional Understanding and Regulation, with the practice and victimization of intimate partner violence, especially with psychological aggression. These findings are found in both correlation analyzes and tests of mean differences between groups of participants. Contrary to this, the correlation results suggest that Emotional Regulation is also positively associated with violent practices, when the analyzes are performed considering the consensus calculation. However, Emotional Regulation (general, without the consensus calculation, as well as the second factor of the facet) was also associated with greater use of negotiation tactics by participants' partners in tests of mean differences between participants. Except for its limitations, this research intends to contribute, through these findings, to the discussion and understanding of both the emotional intelligence construct and intimate partner violence in Brazil, being a pioneering research in the country.

The research aims to analyze the perceptions of teachers-supervisors of the PIBID-UFSCar about the concept of interdisciplinarity during the planning and execution of their actions. To this end, a group of seven supervising teachers who worked in the PIBID-UFSCar selected by the Capes Edital nº 07/2018 was investigated. The study is qualitative in nature. There were two questionnaires as an instrument of data collection: an open questionnaire composed of six questions about the activities developed by the supervisors who worked in the PIBID-UFSCar subprojects during the 18 months, from 2018 to 2020, and a complementary questionnaire, which aimed to characterize, individually, each of the subjects involved. In analyzing the teachers' speeches, we resorted to the studies of theorists who study the concept of interdisciplinarity, such as Japiassú (1976), Fazenda (1994, 2002, 2011), Pombo (1993, 2005, 2008) and the assumptions of the Institutional Project of the PIBID-UFSCar. The results indicate that most of the supervising teachers consider they have developed interdisciplinary practices and the perceptions about the concept of interdisciplinarity permeate the theoretical assumptions of this research in addition to presenting elements of the institutional project to which they are linked, considering the pillars of collaboration and interdisciplinarity of the PIBID-UFSCar. In general, the concept of interdisciplinarity is understood by the subjects as something that transcends the disciplinary character and integrates two or more disciplines. The collaborative principle is also striking in the speeches of the teachers who highlight the School-University planning and the partnerships with other teachers in the school.

The ethanol removal by gas stripping with CO2 offers a potential way to minimize the inhibitory effects of ethanol on yeast cells during the alcoholic fermentation, allowing higher ethanol volumetric productivity compared to the conventional process. In the present study, the hydrodynamics and mass transfer characteristics of ethanol stripping with CO2 were evaluated for different models and working volumes of pneumatic bioreactors, 2.0, 5.0 and 10.0 L. Furthermore, mist eliminators were investigated in order to increase the liquid-gas mass transfer as well as to decrease the entrainment of the droplets carried along with the gas stream, allowing a higher ethanol enrichment in the vapor phase. Firstly, the ethanol removal from alcoholic solutions by gas stripping was evaluated for a 2.0 L pneumatic bioreactor operated in bubble column (BC), concentric-tube airlift (CTA), and split-cylinder airlift (SCA) configurations in order to determine the model that allows higher mass transfer coefficients. The results showed that the three pneumatic reactor models promoted the removal of similar amounts of ethanol in the range of specific gas flow rate investigated. The same behavior was observed for the three scales, although the 10.0 L bioreactor allowed a decrease in the water removal. Then stripping experiments in alcoholic solutions were performed using a 10.0 L bubble column reactor and different prototypes of mist eliminators. It was observed that the mist eliminators were able to enhance the mass transfer, resulting in higher ethanol removal coefficients (kE) and ethanol entrainment factors (FAE), compared with the assays carried out without the device. Finally, extractive ethanol fermentations were conducted in a batch mode using the mist eliminator on the top of the reactor. Monitoring the liquid phase during the extractive fermentation showed an increase in ethanol productivity compared to that obtained in the conventional process. This result was due the use of stripping technique along the cultivation, but it was not because of the mist eliminator effect. On the other side, monitoring the vapor phase revealed that the mist eliminator prototype composed by glass spheres decreased the entrainment of the liquid droplets carried along with the gas phase, resulting in lower water content in the gas stream leaving the reactor, compared to that observed in the extractive fermentation performed without the prototype. Therefore, mist eliminators can increase the ethanol selectivity of this separation process, allowing a decrease in the costs concerning the recovery and concentration of the product removed by gas stripping.

This thesis presents the results of a research that investigated the role of named languages in Spanish learning, supported by translingual practices and socio-community education. The investigation took place in a context of teaching languages for specific purposes, in the Spanish class, inserted in the higher course of Events (formation of the Tourism, Hospitality and Leisure axis, acting in the organization and execution of events), at the Faculty of Technology of the State of São Paulo. The researcher observed, in foreign language classes, the incidence of the use of Portuguese during the activities, as well as other languages that are part of the linguistic repertoire of the students, thus, the Translanguaging theory was used in the studies developed by Canagarajah (2011) García (2014) and Li Wei (2017), who recognize the linguistic repertoire that each individual has to communicate, in a movement that transposes the languages with which they have contact, in order to make themselves understand and understand the other , regardless of the named language used. To help in the quest to understand the adaptations and uses of each subject's repertoire, Social and Community Education was used, which according to Bissoto (2012, 2016), Groppo (2013), Gomes (2008), Antônio (2012) and Miranda (2016) it is understood as a process of listening to different voices that configure the subjects, in an articulation between teaching and community, a socializing education. Translanguaging and Sociocommunity Education can compose a new discussion on education, as both highlight the need for the participation of the family and the community in the construction of knowledge, aiming at a society of greater equity. The research sought to investigate the role of the linguistic repertoire in Spanish learning from the perspective of translingual practices and socio-community education, in order to know how and at what time Brazilian students resort to the use of their mother tongue and/or other languages in the context of teaching languages for specific purposes, in addition to what would be the students' own perception of this phenomenon. The study follows an ethnographic-based qualitative methodology, which listens to the voice of all participants through an interview conducted by the researcher, on the analysis of the transcript of the virtual interaction carried out in pairs and which gave rise to the videos that comprised an evaluation activity of the subject. Data generation took place in four stages, namely: i) conducting a conversation in pairs recorded on video and sent to the teacher; ii) transcription of all recordings by the researcher teacher and subsequent return to the respective pairs; iii) reading and notes by students about the transcribed dialogue; iv) individual interview with each participant, in order to know their perceptions about the notes made both by the teacher and by themselves. The results of this investigation allowed a better understanding of the adaptations and the role of the Portuguese language, as well as the other languages that are part of the linguistic repertoire of students involved in foreign language learning.

Machine Learning techniques have been employed in virtually all domains in the past few years. In many applications, learning algorithms will have to cope with dynamic environments, under both memory and time constraints, to provide a (near) real-time answer. In this scenario, Ensemble learning comprises a class of stream mining algorithms that achieved remarkable predictive performance. Ensembles are implemented as a set of (several) individual learners whose predictions are aggregated to predict new incoming instances. Although ensembles can be computationally more expensive, they are naturally amendable for task-parallelism. However, the incremental learning and dynamic data structures used to capture the concept drift increase the cache misses and hinder the benefit of parallelism. In this thesis, we devise a method capable of reducing the execution time and increasing the energy efficiency of several bagging ensembles for data streams. The method is based on a task-parallel model capable of leveraging the natural independence of the underlying learners from this class of ensembles (bagging). The parallel model is combined with a mini-batching technique that can improve the memory access locality of the ensembles. We consistently achieve speedups of 4X to 5X with 8 cores, with even a superlinear speedup of 12X in one case. We demonstrate that mini-batching can significantly decrease the reuse distance and the number of cache-misses.We provide data regarding the trade-off regarding the reduction of execution time with a loss in predictive performance (ranging from less than 1% up to 12%). We conclude that loss in predictive performance depends on dataset characteristics and the mini-batch size used. We present evidence that using small mini-batch sizes (e.g., up to 50 examples) provides a good compromise between execution time and predictive performance. We demonstrate that energy efficiency can be improved under three different workloads. Although the biggest reduction in energy consumption happens in the smallest workload, it comes at the cost of a big delay in response time, which may hinder the idea of real-time processing. In the higher workloads, however, the proposed method presents a better performance in both the energy consumption and the delay in response time when compared to the baseline version. We evaluate our method using many hardware platforms, with a total of six different hardware platforms used among all experimental frameworks. At the same time, we use up to six different algorithms and up to five different datasets on the experimental frameworks. By providing data about the execution of the proposed method in such a wide range of setups, we believe that the proposed method is a viable solution for improving the performance of online bagging ensembles.

Differently from the classic concept of alloy design, which is based on selecting a main element and adding others to guarantee specific properties, a new strategy has been used in recent years for the so-called multicomponent alloys or high entropy alloys, which do not have a single main element. The most famous and commonly studied was the Brian Cantor’s alloy Fe20Cr20Mn20Ni20Co20, which shows a face centered cubic structure and excellent properties at room and cryogenic temperatures. Further studies showed that the ternary equiatomic alloy Cr33Co33Ni33 had a strength and ductility combination superior to that of the quinary alloy, indicating that the mechanical strength is not only a function of the number of elements, but also of the type of element used, with Cr being the most promising in increasing the alloy strength. Based on previous research, the Cr40Co30Ni30 (% atomic) alloy was chosen to be studied in this work. The composition was produced on a semi-industrial scale, in ingots weighing approximately 50 kg. The material was homogenized, hot worked by forging and rolling, heat treated and mechanically tested. The mechanical properties were evaluated by tensile, hardness and Charpy-V impact tests at ambient and cryogenic temperatures, on the hot formed and heat treated conditions. It was verified that the melting method and raw material purity used in the melting operation have a direct effect on the type and quantity of inclusions formed. Moreover, despite the material showing good mechanical properties, its production by hot forming is challenging, once it has a strong tendency to surface defects below 900oC.

The pollution of drinking water due to industrial activity in recent decades can have consequences for the supply and health of the population. Advanced oxidative processes (AOPs) such as heterogeneous photocatalysis are investigated in the literature for the development of devices and technologies for the treatment of water and industrial effluents. In this work, a semiconductor was developed and its optical and electronic properties were investigated, which allow the application of this material as a heterogeneous photocatalyst in wastewater treatment. Aluminum samples in an electrolyte solution with and without the presence of niobium ammoniacal oxalate (NAO) were anodized by Plasma Electrolytic Oxidation (PEO) for the adhesion of niobium to the surface of the oxide formed to form the semiconductor. The samples were anodized under galvanostatic mode, with a current density of 10 mA/cm2, for one hour. Using the factorial design tool, the effect of OAN concentration and initial temperature of the electrolyte solution variables on some investigated responses was investigated. Responses of electrochemical synthesis, morphology, composition and band-gap energy of semiconductors obtained from synthesis chronopotentiograms, micrographs, composition by dispersive energy spectroscopy and diffuse reflectance were investigated. It was possible to observe the influence of the variables, in particular the variation in the concentration of the electrolyte solution. Photodegradation tests were performed using methylene blue (MB) and rhodamine B (RhB) solutions at concentrations of 2.5 mg/L and volumes of 5 mL per semiconductor sample under UV radiation. For tests with MB, the increase in temperature and concentration of the electrolyte showed a greater response effect on the heterogeneous photodegradation of MB. It was not possible to reuse semiconductors in MB photodegradation even after cleaning with water, alcohol and acetone. As for the photodegradation of RhB, the sample synthesized under lower conditions of concentration and temperature showed greater photodegradation in the first use after 4 hours under UV light. As for the reuse of samples after cleaning with water, only the sample synthesized under higher conditions of temperature and electrolyte concentration showed significant results in relation to error for up to 3 reuses in the photodegradation of RhB. The study carried out demonstrated the effect of the variables temperature and concentration of the electrolyte on the morphology, composition, and potential for use in heterogeneous photocatalysis.

The present research had as investigative scope an active teaching strategy called Gallery Walk when inserted in the teaching scope of Mathematics and Natural Sciences. Gallery Walk is similar to an art gallery, in which visitors try to understand what the artist expressed through his artistic exhibition. During the activity permeated by this teaching strategy, students can move around the room and talk to their groups with the intention of observing images, posters or even their own work. Along this route, they can contribute with comments, share ideas and request clarification from colleagues about the doubts that have arisen along the way. Furthermore, it is possible that problems-issues or tasks may be introduced to be jointly solved, in order to encourage collaborative work and the active engagement of students. In this sense, this research was guided by the following question: How has Gallery Walk been used in Basic Education, according to scientific productions for the period 2010 to 2020? This research can be characterized as qualitative, exploratory and bibliographical. To answer the research question, a survey of scientific publications was carried out in four online academic search platforms. From a total of 60 items, ten productions were selected and analyzed, as some of them were present in more than one platform. In this way, it was possible to identify the analysis categories for each of the areas. In relation to the area of Mathematics, three categories of flexibility were constructed, namely: broad, intermediate and restricted. And, for Science of Nature, the category entitled walk in the gallery was created. The results point to the positive effects of inserting this active teaching strategy in teaching and learning contexts, especially for the two areas mentioned, in addition to demonstrating the gaps in academic productions about Gallery Walk in Brazil and abroad. Therefore, this research recommends the production of new research on the theme Gallery Walk in other online platforms and filters, as well as works in different areas of knowledge.
