The need to deepen the analysis of geological processes, of combined origin (natural-anthropogenic), in urbanized areas requires a constant review of the methodologies to be used. In this sense, the present research had as objective the construction of a methodological proposal of insertion of geotechnical data of subsoil in the elaboration of a map of susceptibilities to linear erosive processes, in a microbasin of the city of São Carlos-SP, like a fundamental tool in risk management in urban areas. Initially, the evolutionary assessment of the susceptibility and risk maps for erosion and landslide already existing in the state of São Paulo was carried out, and three major groups were identified: geotechnical maps, susceptibility maps and risk mapping. Within the cartographic groups of risk and susceptibility, the studies that included erosive features in their results were highlighted, since erosive processes are the central point of our research work. This survey favored the choice of multicriteria analysis in the development of our methodological proposal. Then, the characterization of the physical environment, the watershed of the Mineirinho river, proceeded through the selection of topographic, anthropic variables and soil attributes (subsoil) considered important in the development of erosive processes. Being chosen: the slope, the curvature of the slopes, the coverage and use of the soil, the vertical variation of the textures of the unconsolidated materials, as well as the geotechnical parameters of resistance to penetration, cohesion, friction angle and specific mass for each material, for consider them relevant in the context of this research. For the evaluation of the geotechnical characteristics of the superficial materials occurring in the studied basin, laboratory and in situ tests of resistance to penetration were carried out, using the STOLF impact penetrometer, as well as the collection and use of pre-existing data from drilling and wells carried out in the study region; constituting the first effort to create a geological-geotechnical database in the UFSCar DECiv. Finally, the 1: 15.000 scale erosion susceptibility map was generated in the Mineirinho river watershed in the city of São Carlos-SP, with detail (1: 2.000 scale) in a region that is currently developing erosion; resulting in the predominance of the "high susceptibility" class, correctly delimiting the most degraded areas, which confirms the influence of evaluated conditioning factors (topographic, textural, geotechnical and anthropogenic) in the potentiation of erosive features.

Leishmania is a protozoa genus with several species of intracellular parasites that cause diseases called leishmaniasis, divided into: visceral (VL), the most serious form that affects internal organs and can lead to death, or cutaneous (CL), attacking the skin or mucous membranes with ulcers. These diseases belong to the group of neglected diseases, because they mostly infect poorer populations and are not a priority for health services, with their specific methods of treatment and diagnosis not reaching the places with the highest number of cases. To solve the problem and increase specificity and sensitivity, we can use specific recombinant purifieds, such as the recombinant protein K39 (kinesin-like protein K39), in the tests. Therefore, the objective of the work was to produce anti-leishmania antibodies from K39 aiming at the development of an immunoenzymatic test. The polyclonal anti-leishmania antibody was produced, qualitatively evaluated by SDS-PAGE polyacrylamide gel electrophoresis, transferred to a nitrocellulose membrane for an Immunoblotting Assay and applied to an indirect ELISA immunoassay for sensitivity analysis. In the electrophoretic profile was possible to observe the presence of two bands, one short chain (25kDa) and one long chain (53kDa), in addition to albumin contamination. The 1: 1000 dilution sample was stronger than the 1: 5000 sample. Different dilutions were tested in Immunoblotting (1:25, 1:50, 1: 100, 1: 250 and 1: 500) and bands were seen in all of them, with the 1: 500 antigen being the most evident, which confirms the reactivity of the antibody produced. For being polyclonal, nonspecific bands were also found. The optical density of the ELISA was measured in duplicate and standardized for analysis, generating satisfactory results for the concentrations of 1: 5000 and 1: 1000, even with this having the last lower result. Consequantly, the K39 antigen obtained values that enable its use in diagnoses for leishmaniasis.

In the area of Human-Computer Interaction (IHC), evaluations help to know the desires and problems that people face when interacting with user interfaces (UI). Evaluations can be carried out in order to investigate aspects such as usability, accessibility, communicability of systems and the emotional response of users. There are some methods and ways of inspecting and classifying emotions evoked by UIs, such as physiological signals. However, most instruments for measuring physiological signals are expensive, invasive and use complex equipment. The Semiotic Inspection Method for evaluating Emotional responses (MISE) is a cheaper and less laborious alternative for evaluate the emotional state, as it does not require the participation of users to be applied. Several automatic searches were performed on search engines and few of the works found attempted to evaluate the effectiveness of an analytical method. For this reason opted for manual search, through the procedure of Snowballing. With this procedure, 32 studies were found that evaluated the effectiveness of analytical methods through comparisons with empirical methods. But, in most cases, the studies compared UIs usability methods and none analyzed methods of emotional response from users. There are studies in the literature that evaluate the feasibility of MISE, but so far, the effectiveness of MISE compared to other methods that evaluate the emotional response of users has not yet been measured. This research project aimed to evaluate whether MISE is effective to predict the emotional response evoked by UIs. For this, two empirical studies were carried out: (1) comparison of a gold standard (results from the application of MISE by the method proponent) with physiological signs and subjective feelings collected from 24 users and (2) comparison of the results of MISE applied by 9 IHC scholars versus a gold standard. In study 1, users had the signs of cardiac activity, brain activity and skin electro conductivity captured, while performing tasks in three types of UI: a game, a website and an application. In study 2, the researchers received training on the application of MISE and carried out inspections on the same 3 IUs used in the study with real UI users. At the end of the collection, comparisons were made between the empirical studies. The results suggest that the MISE proved to be easily apprehensible for HCI scholars, with no experience in applying the method. The data collected through physiological signals suggest that MISE can be effective in predicting the emotional state of users on site type UIs. And it is not effective on game and application type UIs. The markings of the volunteers in the collection of subjective feeling suggest that MISE can be effective in predicting the emotional state of users in game and application type UIs. And not effective on site type UIs.

Schools inserted in quilombola contexts face challenges that go beyond an adapted Pedagogical Political Project. In this study, local narratives about education in the Pedro Cubas and Pedro Cubas de Cima communities (Vale do Ribeira, SP) are presented. Narratives are discussed in light of the challenges of integrating traditional knowledge and formal education for local children and adolescents. Data were collected through informal interviews and daily life observation in the context. The results showed aspects of life history, socialization, and reflections on education of eight individuals, among quilombolas and teachers who work in the region. School transport conditions were within the main difficulties reported. Proposals and local actions for the inclusion of differentiated teaching in the school curriculum could be also reported. However, the challenge of a more effective and permanent integration between quilombola culture, local knowledge, and formal education in schools remains. The school, seen as a multicultural and democratic environment, impacts positively not only local populations but the society as a whole.

Brazil stands out worldwide in the sugar-energy sector, in world rankings it presents itself as the largest producer and exporter of sugar and the second largest producer of ethanol. In this sense, it is important to better understand the productive dynamics of sugar and its economic variables (domestic and international prices) to contribute positively to the strengthening of public policies and actions of the private sector. Thus, the general objective of this work is to analyze the productive and economic dynamics of Brazilian sugar between the 2003/2004 and 2019/2020 harvests, through selected economic variables and the calculation of correlation index. Specifically, to identify periods of variations in sugar production, followed by a qualitative analysis of these periods, as well as to verify the correlations between sugar production and product prices in the domestic and international markets. This research has an exploratory character, with the use of secondary data, obtained through bibliographic reviews, encompassing books, academic papers, websites of public and private institutions, etc. Pearson's Correlation Index was used to calculate the correlation between the sugar production variable and the variables of domestic and international prices. As results, positive correlations were found between: sugar production and product prices in the domestic and international markets; domestic and international sugar prices. Six periods with variations in sugar production were also identified and their respective qualitative and quantitative analyses were made. Moreover, as expected, it could be inferred that Brazil does not dictate the price of sugar in the foreign market, but has an active participation in it, much due to being the largest producer and exporter of this commodity. It was possible to conclude that the production mix of sugarcane depends on complex analyses and several factors, many of them including at global levels. However, the destination of sugar to the international market is historically consolidated and this was found during the period analyzed. Finally, it is concluded that the productive dynamics of sugar is important for the decision-making of the private sector, guideing the right amount and time to sell sugar in the domestic and/or international market.

The Food Acquisition Program (PAA) and the National School Feeding Program (PNAE) are public policies that have among their purposes: promoting access to food and encouraging family farming. This work has the object of study, using the case study and action research as a methodology, to analyze the shopping experience of the Federal Institute of Education, Science and Technology of São Paulo - Avaré campus together with family farming. As for the case study, it refers to the shopping experiences, comprised in the period from 2016 to 2019, when the federal autarchy started the execution of the PNAE using the Avaré campus as a pilot project. As for action research, it is supported by the fact that the researcher participated in the purchases made during this period. The data collection of the work was done through interviews with family farmers who participated, participate or never participated as beneficiaries of these policies for the IFSP - campus Avaré during the studied period. In addition to the interviews, the documentary research that brought data from notices, contracts, sales projects, among other documents, as well as the participant observation that brought contributions in the analysis of the results obtained. Finally, as regards the results, the importance of executing these purchases for family farming can be seen, demonstrated by the farmers' perceptions mainly regarding the share they represent in their incomes. However, they point out that, among the main difficulties, marketing prices are not interesting and also problems with transportation, which must be evaluated by Organs executing agencies. As for the possibilities of approximation among stakeholders, there is a need for approximation to resolve the difficulties mentioned, but positively there is an intention of involvement by the interviewees in participating in these discussions. Finally, in the context of the pandemic, it appears that there was a negative economic impact on income for farmers benefiting from these public policies due to the suspension of school deliveries, corroborating the importance and positive impact that these public policies represent for these family farmers.

Fertilizers have been used as agricultural inputs to allow maximum yield during the growth of crops. One of the significant challenges is the efficiency of the plant's nutritional process. It is necessary to use excessive amounts of nutrients to minimize losses due to leaching and aerial dispersion processes, leading to economic and environmental contamination. Potassium is one of the essential fertilizers used in agriculture, and like the others, it is mainly provided by import. Thus, the present research project aimed to develop biodegradable starch sachets for packaging and potassium fertilizer release. However, starch materials are subject to the loss of initial characteristics due to the degenerative retrogradation effect, high hygroscopicity, and easy proliferation of microorganisms, decreasing the shelf life until application in the field. In this sense, for the best performance, the presence of citric acid was evaluated, aiming at the esterification of starch and the insertion of faujasite zeolite (FAU) reinforcement materials modified with Cu2+ and CuO nanoparticulate ions. Copper is one of the micronutrients used to develop plants and presents antimicrobial properties, enabling more remarkable preservation of sachets. The CuO nanoparticles and the FAU were obtained by quicky precipitation and the hydrothermal treatment methods, respectively. The processing of the films that make up the sachet was carried out from the homogenization of the starch under temperature, in the presence of water and urea, acting as plasticizer and source of nitrogen for the plants, followed by thermo-pressing. In the starch films, it was possible to obtain a matrix with 25% (w/w) of urea, enabling the polymeric matrix to be more ductile. When inserting the reinforcement materials, it was possible to verify that CuO at a concentration of 1% (w/w) showed an increase in tensile strength of about 120%, a result similar to that found for the FAU reinforced film in the concentration of 3% (w /w) and with the presence of citric acid. All copper-containing films showed a fungistatic effect for the fungus Alternaria alternata, a microorganism very susceptible to sources rich in carbohydrates. Besides, the film containing 1% (w/w) CuO of nanoparticles showed protection against visible and ultraviolet radiation. In the release of KCl in sachets, it was possible to observe K+ ions rapid availability when coming into direct contact with the aqueous medium, thus enabling a quick action with the external medium. Upon the release of urea, all sachets showed a similar value after 60 days, indicating equivalent matrix degradation. For the Cu2+ nutrient, it was possible to observe that the FAU film with citric acid below releases the ion, possibly due to the more stabilization of the cation in the matrix. In this way, starch sachets were obtained with promising properties that increase fertilizer commercial application viability.

The Education of Youths and Adults - EJA, in the contemporary world, is notorious as a modality of teaching basic education, claimed by the Brazilian jurisdiction as a fundamental right, repairing - of an emerging trend - the historical-social debt to those who have been denied their right to education in the own age. Such a situation emerges in the current compensatory, equalizing and qualifying character of public policies, whose effectiveness in combating illiteracy and its setbacks has, over the past decades, been inept, flawed. In view of this, it was pertinent to ask, due to the object of the present research, “what initiatives, at the level of public policies of the Jair Messias Bolsonaro Government, were taken for the Education of Youths and Adults in Brazil? ”. In order to elucidate the issue, we opted for the development of exploratory research of a qualitative nature (MINAYO, 2002), by means of bibliographic and documentary analysis, using specialized literature of current research and national norms. It was found, after observing historical and current indications, regarding the path of consolidation of the modality - from the colonial to the republican period, that contemporary public policies aimed at EJA, before and during a period of historical exceptionality posed by the Covidean pandemic 19, have configured public neglect and emergency actions, sometimes palliative, sometimes insufficient, which has substantially affected the access and participation of students, considering, among other factors, the dismantling of institutional structures and the reorganization of the school calendar under circumstances of social isolation and sudden adaptation to the unusual demand for remote, or non-face-to-face teaching, whose ordering in the public educational system proved to be incipient.

In dementias, alterations in brain functioning and progressive and global loss of cognitive functions are observed, interfering in the individual's social and occupational activities, with Alzheimer's disease (AD) being the main one. Mild neurocognitive impairment (MCI) can be considered a transient phase between normal cognition and AD and biomarkers that can diagnose these diseases in their early stages, preferably in samples that do not require highly invasive collection procedures, are the target of many recent studies and present a major clinical challenge in the area. AD is strongly related to the formation, accumulation and aggregation of the β-amyloid peptide (Aβ) in neurons. This molecule is formed by the sequential cleavage of β and γ-secretases, via a pathway called amyloidogenic. On the other hand, the sequential cleavage by α and γ-secretase, by the non-amyloidogenic pathway, prevents the formation of neuronal Aβ, and consequently, the appearance and advancement of AD. ADAM10 is the main neuronal α-secretase and is also present in platelets, white cells and CSF. Studies by our and other research groups indicate that the levels of active ADAM10 in platelets of patients with AD are decreased compared to healthy subjects. Thus, ADAM10 is a strong candidate for blood biomarkers for AD. In this sense, this study aims to evaluate the levels and activity of ADAM10 in the blood plasma of subjects with AD and MCI, in order to support the function of this protein as a biomarker for these conditions. Previous results from our group allowed us to elaborate the hypothesis of this study that the levels of soluble and therefore possibly inactive ADAM10 in the plasma of subjects with MCI and AD would be increased, compared to the levels of cognitively healthy subjects.

This work sought to understand the subjective articulation that young people who attended higher education - undergraduate or graduate and, simultaneously, work in the informal market do between professional training, informal work and employment. Specifically, it intended: to investigate the meanings attributed to professional training, to investigate reasons and forms of insertion in informal work, as well as the routine and strategies defined to reconcile studies with work, and to understand the expectations and life project of these subjects. The method used was qualitative, through semi-structured interviews conducted with the participants, which were recorded and transcribed. The recruitment of participants took place using the snowball sampling technique. The analysis of the interviews was based on the thematic content analysis of the transcribed interviews, presented by Minayo, Deslandes & Gomes (2007). Four categories of analysis were highlighted from the transcripts of the interviews, which are: life project, course and academic experience, work, economic conditions and student assistance. It was possible to observe the dialectical nature of life projects, the influence of the socio-political-economic context on them, the variability of reasons why young people enter higher education and also the variability of reasons why they enter the world of informal work, the different forms of conciliation between study and informal work, the different impacts brought by informal work simultaneously with studies, and the importance of public student assistance policies.

Heavenly bodies can be observed everywhere in the night sky. With the naked eye we can identify around 6000 stars spread across 88 constellations. Faced with this countless number of stars, astronomy offers us the opportunity to explore the foundations of science and mathematics better than any other area of knowledge. Visualization plays a very important role in the teaching of science and mathematics. In this sense, Observational Astronomy can offer a wide range of options for the introduction and discussion of various subjects. In addition to the indisputable motivational characteristic for teaching science, astronomy updates and immerses us in an atmosphere of incredible scientific achievements and technological evolution. In view of this motivating and effervescent scenario of knowledge, we describe in this work an alternative to introduce the teaching of astronomy through observational astronomy, having the night sky as a laboratory and our eyes as the first measuring instrument to start the long journey of unraveling the mysteries of the universe. In this sense, everyone, from elementary school or undergraduate students, who have a more intimate contact with academic life, to the general public, has conditions and the potential to explore science and mathematics at the level they find most convenient, just by going deeper into his studies on observation techniques, technologies and instrumentation and why the universe behaves the way we see it. Here we explore the first steps to historically discuss the evolution of cultures of ancient people through theories and observations of the night sky with the naked eye. We also briefly address the most used coordinate systems to assist observers to locate themselves on our planet and the stars in the sky, the most well-known catalogs of celestial bodies, some of the phenomena and objects observed with the naked eye and the evolution of observational instruments. Furthermore, we present results obtained from naked eyes observations, recorded by an DSLR camera on an altazimuth tripod and how to treat the images in the open source software Astrometry to identify the stars and constellations in the region of the observed celestial sphere. We hope that this work can be useful to introduce astronomy in science-based courses such as Physics, Chemistry, Biology and Engineering, to help students in the process of scientific literacy for areas of advanced research as well as in the fundamental role that science has in society.

Based on the perception of the risk that the daily handling of fire can cause fires in buildings, shops, schools, public and historical heritage, it is necessary to improve the current conditions to contain it. Firefighting is carried out using a large amount of water that needs to be available at a distance and under conditions adequate to enable the service of the Fire Department to be efficient. It is in this scenario that the hydrant flow is so important as an object of study. That This work is justified by suggesting the development of a simulation technique computational, based on field measurements that allow the simulation of the opening of a hydrant in a distribution network using the EPANET software, which does not allow direct consideration of accessories. Thus, the objective was to obtain the available flow in the water supply system, as well as determining the discharge coefficient for short tubes, measure the flow in the field and propose an adjustment of the coefficient of hydrant discharge considering the pressure and flow measured in the field. As for methodology was based on the development of a model in EPANET that enabled determine a theoretical discharge coefficient for use in short tubes, making the considerations of actual effects by considering the head loss coefficient (K). As well as, the survey in the field with pressure measurements next to the water distribution in order to determine the flow, determination of the flow through of a theoretical formulation by measuring the hydrant water jet and subsequently, an adjustment of the theoretical model was carried out in EPANET. With the construction of the model computational, it can be concluded that the emission coefficient (CE) is influenced proportionally across the transverse area of the outlet nozzle, moreover, for higher values or equal to 3000 L.s-1.m-0.5, resulted in a stable flow and it was observed that it can be used in discharge branches with DN equal to or less than DN200. For the proposal of hydrant column modeling, using VRP (fictitious) the results were shown satisfactory and consistent with the flow values provided by the fire department, considering the nozzle diameter of 63.5mm and the pressure loss coefficient (K) - Loss Coeff, 1.55. Because the data comes from tabulated data interpolation, these must be viewed with caution, as there is no knowledge about the origin of the values taken in the table.

In the evaluation of the service limit state, the Brazilian standard ABNT NBR 7190 (1997) recommends the adoption of the mean value of the elasticity module to compression in the direction parallel to grain (Ec0,m) for all the members of the structure. Due to the variability of the wood, this methodology can generate vertical displacements higher than the limit established by the regulations (L (span) / 200), which can cause pathological manifestations in the structure. In order to evaluate the influence of the adoption of Ec0, m for all the truss bars in the calculation of displacements, mechanical properties of the species Angelim Ferro (Hymenolobium sp) and Angelim Pedra (Hymenolobium petraeum Ducke) were obtained through experimental tests, according to the normative specifications of ABNT NBR 7190 (1997). With the aid of numerical models developed in ABAQUS® and the experimental values of the mechanical properties, 10 typologies were analyzed (Porch, Inclined Banzos, Upper Inclined Banzo, Parallel Banzos, Bowstring, Fink, Howe, K Truss, Pratt, Scissor), 3 spans (5, 10 and 20 meters) and 2 species (Angelim Pedra and Angelim Ferro). Initially, adopting the Ec0, experimental for all bars and performing a linear analysis, the loads to generate a displacement of L/200 for each combination of parameters were determined. In the next step, using the loads previously defined, random experimental values of stiffness were assigned to each element of the truss and, through geometric nonlinear analyzes, the maximum displacements of each model were obtained. Based on the results of 1260 numerical simulations, displacements greater than the reference value (L/200) were obtained in 17.32%, 30.18% and 34.80% for spans of 5, 10 and 20 meters, respectively, suggesting that the methodology proposed by the standard may generate excessive displacements. These excessive displacements can cause pathological manifestations in the structure, reducing its useful life. This problem can be overcome with the use of non-destructive methods in the pre-classification of the structure bars, positioning the elements rationally in the regions of greatest demand.

Indirect somatic embryogenesis (ISE) is one of the most used regeneration pathways to obtain sugarcane genetically modified plants. ISE regulatory genes have been widely studied in monocotyledonous and dicotyledonous plants, and act as activators of the expression of gene cascades or promoting cell growth and differentiation. In contrast, in sugarcane, there are few reports in the literature with these genes involved in ISE. Thus, the present study aimed to i) search for putative homologous genes responsible for the regulation of ISE (families: BABYBOOM, WUSCHEL, LEAFY COTYLEDON, VIVIPAROUS1, and AGAMOUS-LIKE) in sugarcane (SP80-3280 and Saccharum spontaneum); ii) analyze the phylogeny between the sugarcane amino acid sequences and their homologous in Arabidopsis thaliana and Poaceae species; iii) design ideal primers for studying the expression of sugarcane ISE-related genes. BLAST and BLASTp searches were carried out in the Phytozome, NCBI, UniProt, and Gramene databases to obtain homologous sequences of the five gene families in corn, sorghum, rice, and A. thaliana. Thus, phylogenetic analyzes of amino acid sequences were performed with the aid of the software CLUSTALW and MEGAX, which showed evolutionary proximity between the proteins of Zea mays, Sorghum bicolor, S. spontaneum, and SP80-3280 in all the studied genes. In silico analyzes indicated that they may have more than one gene from the BABYBOOM, WUSCHEL, and VIVIPAROUS1 families regulating the pathways of ISE in sugarcane. In addition, with the aid of the PRIMER3 software, 8 pairs of primers with ideal parameters were obtained to be used in future analyzes of gene expression to understand more deeply the mechanisms of ISE.

The travestis who work in the sex market reveal a close relation between their activities in these markets and territorial displacement. Studies usually address this subject based on the notions of stratification, status and distinction. Wish basis on the discussion on mobility and travestis, I present an expansion of the notion of displacement in order to highlight it as relation, sense and knowledge in order to understand some of the internal production processes of the travesties. That meant thinking about geographical shifts, but also the travestis' knowledge which derives from not having a safe port, not really belonging anywhere, getting a reference for the next thing, moving on recklessly and traveling to learn. I analyze the various meanings that displacement can reveal about the dynamics of existential movements of travestis, associated with transit activities between cities and places. I have identified evidence of these displacements between Brazilian cities and carried out fieldwork in three of them: São Carlos/SP, Campo Grande/MS e Franca/SP. The ethnographic study helped broaden the understanding and notion of displacement to better understand the displaced dynamics of experiences where mobility, relations and the travestis’ production of the body-gender occur, not as the motivation for the displacements, but in the midst of them.

This dissertation is linked to the Education of Teachers and Other Educational Agents research group of the Post-Graduate Program in Education - Master and Doctorate - from the Federal University of São Carlos (UFSCar). The general objective of the research was to analyze the contributions and limits of Pibid in the formation of reflective teachers, pibidians of Pedagogy between 2014 and 2016, years with the largest grant of scholarships from different Higher Education Institutions in Brazil. The specific objectives sought to identify, from the perspective of the graduates, the contributions and limits of Pibid in teacher education, to understand whether Pibid has been configured in a space for reflection on teaching practice and how it is done, in addition to analyzing which aspects / elements of Pibid can be configured in tools that enhance participants' learning and how they can promote the development of a willingness for reflection, following a qualitative approach of the descriptive-interpretative type. Data collection was performed through the application of a questionnaire and five interviews with a semi-structured script, in order to find out who the Brazilian pibidians are and whether Pibid was a space for reflective training. The results show that Pibid is an important program for initial teacher education and that through professional insertion, as well as through different training practices, it provided several contributions in initial teacher education such as: the possibility of articulation between theory and practice; maintaining the student's permanence in graduation; the possibility of dedicating oneself only to studies; participation in scientific events; promoting the reduction of the “reality shock”; the possibility of learning from living in the school routine and the reframing of the profession. The limits listed by the pibidians, however, were the low value of the scholarship, the distance between the program coordinator and supervisor, the low scope of Pibid and the few moments of reflection. Despite the limits, all Pedagogy pibidians (2014-2016), considered Pibid as a fundamental element in their education, and many showed that Pibid was a program that provided moments of reflection on their practices, so we consider that Pibid collaborates grandly for the formation of reflective teachers in Brazil.

Lignocellulosic materials comprise solid urban, industrial, agricultural and wood residues that are the target of several researches with the objective of producing several products with higher added value. Its composition contains a hemicellulosic fraction that when undergoing a pre-treatment generates fermentable sugars such as D-xylose which, by the action of a microorganism, can be converted into xylitol. In turn, xylitol is a polyalcohol with applications in the food and beverage industry, in medicine and dentistry, and obtaining it biochemically is still a challenge. Among the microorganisms capable of producing xylitol, yeasts from the strains of the genera Candida, Pichia and Saccharomyces are some of the most studied. Thus, in this context, the objective of this work was to evaluate in silico, using some optimization methods available in the opensource software OptFlux, the genetic modifications with the potential to increase the production of xylitol from hemicellulosic material in the metabolism of the yeast Saccharomyces cerevisiae, which has a favorable database and is already used industrially to obtain ethanol. The highest production of xylitol was 11.96 mmol/gDCW/h obtained with only 5 changes in the metabolic model of yeast, of which four reactions present in the Glycolysis pathway were deleted and one reaction present in the Pentose and Glucuronate interconversions pathway, which contains the target metabolite xylitol, was under-expressed.

The present study is a bibliographic research in the field of early childhood education. It analyzes the distribution of works relative to the period of 2010 to 2020 on pedagogical documentation with a focus on Ministories. It seeks to answer questions about how pedagogical documentation is conceived in the surveys raised and how mini stories behave as an object of study within the theme addressed. A total of 39 papers were found on digital research platforms, including articles, course completion papers, dissertations and theses. The research presents significant data on how the pedagogical documentation is object of reflection / action / investigation of the teaching work, allowing the children's protagonism and the mini-stories appear as a documentation procedure, still little known and explored.

Traducir una obra literaria a otra lengua es un hecho complejo, aún más cuando las dos lenguas son semejantes. La relación del español y del portugués brasileño está marcada por una “transparencia engañosa”, según Kulikowski; González (1999), y el proceso de traducción entre las dos lenguas involucra una reflexión y una investigación acerca de tal complejidad lingüística. A causa de eso, en este trabajo, hemos propuesto un estudio de los verbos poner y “pôr” a través de la comparación de la obra mexicana Como agua para chocolate (1989), de Laura Esquivel, con su traducción, hecha por Monica Maia, al portugués brasileño. Nos basamos en los usos de los verbos presentes en los diccionarios, artículos cuyos temas se relacionaban con los verbos em cuestión e investigaciones que trataban del proceso de traducción (AUBERT, 1998 e SILVA, 2015). Se hizo una cuantificación de los verbos poner y “pôr” en los dos textos literarios, en busca de los usos equivalentes y distintos para intentar comprender los significados por detrás de las elecciones de la autora en la obra original y también, por consecuencia, de la traductora, que es la persona responsable por crear un puente entre las dos lenguas y culturas. Como resultado, hicimos un relevamiento detallado de los usos de poner y “por” en la obra original y su traducción que podrá ser utilizado en investigaciones futuras. Verificamos una pluralidad de elecciones verbales hechas por la traductora que están más allá de nuestras las ideas iniciales de que había una traducción literal de los verbos a causa de sus significados en los diccionarios. Además, identificamos también usos específicos del verbo en español.
