    The newest far-right authoritarian wave in Brazil, represented primarily by the coming of some sectors of the New Right reaching power, is not necessarily something new in Brazilian history. Considering it is that even before the military dictatorship, it had been a mass movement that had a far-right nature and an undemocratic point of view named Ação Integralista Brasileira, and just as recent movements it also spread to society through its intellectuals located in strategic places in society. Thus, the research question: "What the Brazilian integralist intellectuals can teach us about the intellectuals of the New Right?" becomes indispensable. The intended purpose is to analyze the arguments and discourses in selected works of five intellectuals, three of Brazilian Integralism (Plínio Salgado, Gustavo Barroso, and Miguel Reale) and two of the New Right (Olavo de Carvalho, Rodrigo Constantino). The object of study to be analyzed will be the relations between the intellectuals of both movements. For that analysis, it will use the qualitative approach to its methods to analyze its similarities and dissidence.

    The present study, grounded in a critical and reflective analysis of the author's formative journey, sheds light on relevant concepts for the construction of the medical professional identity in students — a theme gaining prominence in various medical schools worldwide, emphasizing the importance of education focused on character development and the promotion of virtues. The objective is to investigate how the constructivist educational model and the integrated theory-practice curriculum, both foundational aspects of the UFSCar medical course, influence identity formation. Additionally, the study seeks to reflect on intrinsic and extrinsic factors affecting students that facilitated or hindered such formation. A qualitative methodological approach was adopted, supported by data triangulation analysis, grounded in extensive systematic reviews and qualitative metasyntheses on the subject. Data were collected and analyzed with a phenomenological emphasis, centered on reading and interpreting entries in the student's reflective portfolio. These were presented in synoptic tables condensing practical elements derived from dialogues with authors, outlining their influence on medical identity construction, and specifying intrinsic/extrinsic facilitators and barriers to formation. The finding that early exposure to professional practice in this educational model significantly and positively influences various aspects of medical professional identity formation is a noteworthy contribution of this study. Similarly, the constant emphasis on activity reflection and encouragement of active learning reinforces the conclusion that new medical courses with constructivist methodologies are more aligned with the identity formation of physicians who genuinely adhere to societal principles. However, areas requiring improvement and constant vigilance were highlighted. More than a synthesis of the student's practical journey, this study constitutes an object contributing to the construction of the author's professional identity. It is the composition of a symphony whose notes are intrinsic to experiences that have been reverently embraced. Revisiting the past illuminates the path of the present, providing insights that transcend time and guide the future journey.

    The present study seeks to assess the productive capacity of seedlings and seeds in Brazil, identifying the main actors in the reforestation market and the associated challenges, in the context of the goals established by the Paris Agreement. The methodology employed involves literature review and quantitative analysis, aiming to detail the role of the companies involved and the dynamics of this market. The results showed a notable growth of the sector after the Paris Agreement, highlighting the consultancy services and the generation and commercialization of carbon credits. However, currently, without considering the country's natural regeneration, the production of seedlings and seeds is insufficient to meet the reforestation target of 12 million hectares committed at COP21. The contributions of this work are significant for the decision-making by companies, investors, research institutions, and public policy makers, providing a knowledge base that can guide initiatives to achieve environmental sustainability goals and position Brazil as a leader in low greenhouse gas emissions. The discussion emphasizes the need for expansion and improvements in the seedling production segment, both in terms of quantity, with the construction of more nurseries, and quality, through the development of new technologies, reproduction protocols, and the development of new public policies that facilitate this process. The conclusions point to the urgency of strategies addressing the gap in production and the lack of skilled labor, proposing measures for the training of professionals and the encouragement of reforestation project execution.

    The development of integrated biorefineries, based on the complete utilization of plant biomass and the production of bioproducts such as biofuels, is an important strategy in replacing the global energy matrix with more sustainable processes, thus contributing to decarbonization and reducing dependence on fossil resources. However, one of the main obstacles still encountered is that the use of some plant biomasses, such as sugarcane and corn, raises the debate of competition between advances in bioproduct production and food production. According to the United Nations (UN), the world population is growing at an accelerated pace, resulting in an increasing demand for food to meet the needs of this expanding population, making food security a priority in the strategic plans of countries. In this context, this work aimed to conduct a critical analysis of the impact of bioproduct production on global food security. For this purpose, a comprehensive literature review was conducted on the discussion related to the use of food resources and agricultural land for bioproduct production. Different perspectives were explored based on real data obtained from public reports and published studies. One of the central discussions is the need to find alternatives to increase the productivity of land dedicated to food production, as well as the development of new technologies for the production of alternative foods, such as plant-based protein, which can help meet the population's demand for quality nutrients. Additionally, second-generation raw materials (2G) are explored as a strategy to increase bioproduct productivity without using food raw materials. Finally, it was identified that waste has a much greater impact on food security than biofuel production.

    Early Childhood Education, the first stage of Basic Education, includes the dimensions of caring, educating and playing. This phase is responsible for the child's first contact with a new environment, routine and people, moving them away from their family environment. Therefore, attention is needed during this period of adaptation, with the family being the protagonist and fundamental to its success. When you have a child with a disability or autism, family dynamics undergo changes, which must be based on the specific needs of the children. Thus, when entering Early Childhood Education, children with disabilities can cause insecurity in their parents. Establishing a relationship of trust between the family and the school becomes essential in this scenario. Therefore, the present study sought to analyze the school adaptation of children with disabilities, according to the families' opinions. The study design was descriptive and exploratory in nature. It had the participation of five parents, who carried out the interview in person or remotely, depending on their preference, guided by a semi-structured script. Through the results, it was understood that families enrolled their children with disabilities in Early Childhood Education with a view to their development and socialization. However, in some cases the adaptation process is still not successful, mainly because there are no exchanges with the institution before entry and during the child's stay at school. Legal services and adaptations to activities have not yet been observed, requiring the child himself to adapt to what was offered. The Early Childhood Education institution contributed to the development of children, from the parents' perspective. Furthermore, the effective relationship between the family and the school is not present, contributing to the feeling of distrust in relation to the work carried out by education professionals. For effective communication, it is important to invest in continued training of the school team, quick and easy contact between both parties and the promotion of an inclusive school culture, which provides space for parents to express their concerns, benefiting the school community as a whole

    Chromatographic processes are extremely important for protein and other biomolecules with high added value purification and represent a large portion of the production cost in the industry. Ion exchange chromatography is a widely used chromatographic method for separating proteins on a preparative scale, based on their interaction with positive or negative charges present in the stationary phase with the starting chemical components on the liquid phase. In each chromatographic process, operational conditions need to be evaluated, both in the loading and elution stages. There’s a variety of factors that impacts the process and its quality. Among the most important factors are the characteristics of the mobile phase, such as the concentration of chemical components, equilibrium shifting agents, the medium ionic force and the pH. The development of chromatographic processes is dense and expensive, and the application. Thus, the work proposes the use of a scheme with pipette tips loaded with anion exchange chromatographic resin. Q-Sepharoses and BSA protein were chosen for the tests. To obtain parameters that characterize both the loading and the elution part of the chromatographic process, the influence of an equilibrium shifting agent (NaCl) was evaluated. In experimental terms the process for washing the tips was defined, allowing them to be reused in the tests. Finally, it was verified that this method presents consistent and reproducible results for obtaining these parameters, bringing benefits in relation to the amount of material used, reducing costs and the time to obtain these parameters.

    The presence of women in the academic world has been fraught with difficulties throughout the history of science. Even though they are gradually conquering their space, there is still a great deal of differentiation between men and women, such as the segregation of areas of knowledge considered feminine and masculine. One of the causes of this issue is the presence of stereotypes about the image of the scientist, who is often seen as a man, wearing a lab coat, with messy hair, dark circles under his eyes, crazy, among other adjectives. In this context, this study aims to map the perceptions, classified by age and gender, of students aged between 8 and 17 about scientists and the presence of women in science and to propose an intervention through the production of a podcast. The activity was divided into two stages. First, the students were given a questionnaire and took the "Draw a Scientist" (DAST) test in order to understand their preconceptions about scientists. In the second stage, the students discussed the presence of women in science, using another questionnaire and the presentation of educational videos about female scientists. With this information, they discussed their perceptions and hypotheses about the reasons for not knowing about women scientists, as well as the difficulties of being a woman in science. In order to spread the word about women in science, a podcast was produced. The results showed that the students had the same stereotypical ideologies about scientists as those reported in the literature and initially believed that the invisibility of women in science was their own choice. During the discussion, the younger students showed a certain immaturity and did not understand the importance of the debate, but the girls (of all ages) and the older students showed concern and anger about the issue. In conclusion, the work achieved its objective by investigating students' perceptions of scientists and introducing them to women in science, with the difficulties they face. In addition, the proposed intervention through the podcast allowed us to go beyond the scope of research and advance scientific dissemination, as well as contributing to a critical-citizen education.

    The rapid growth of urbanization and globalization has transformed eating habits, driving migration to urban areas and the rise of the fast-food industry. This has resulted in foods high in fat, sodium and sugar, contributing to health problems such as obesity and cardiovascular disease. In recent years, there has been growing consumer awareness about the interaction between food and health, driving the search for more resilient products, less loaded with chemical additives and with greater transparency on the labels, giving rise to the concept of “clean label”. Despite having existed since 2012, the concept still lacks a clear definition, being subjective for consumers and industry. The search for safer foods has driven research into products with simple ingredients and minimal processes, updated by literature reviews for consumers and industries on what defines a "clean label" food. This demand led to reductions in the consumption of elements such as fat, salt, sugar and processed foods. Companies are innovating to offer transparency and healthier products, driving the growth of more natural foods compared to conventional processes, meeting the demands of modern consumers. Concern about food allergies and intolerances has led to a search for healthier diets, driving the industry to develop products without gluten or lactose. Nutritional labeling is essential to prevent health problems, being a means of communication between the product and the consumer, bringing regulatory changes that highlight interesting health news on the labels. The clean label movement has driven large investments in innovation, reduction of additives and adjustments in food formulation to meet consumer demands. The industry faces challenges in simplifying ingredients without compromising the sensorial characteristics of foods, while future trends indicate a growing association of clean label products with organic certifications and a focus on sustainability and quality, in production and in the final product, respectively. Large food companies are adapting through mergers, acquisitions and investments in innovation to meet growing demands for healthier and more transparent food.

    Currently, one of the main routes for obtaining hydrogen is the steam reforming of methane, it is known that the global demand for hydrogen has intensified in recent years, being a potential candidate for the clean and sustainable energy future, however, It is necessary to pay attention to the emissions of polluting gases into the atmosphere, in this aspect, the steam reforming of methane is unfavorable, emitting gaseous pollutants in significant quantities. The thermal decomposition of methane (TDM) is a process that occurs at high temperatures, with or without the presence of a catalyst, forming only hydrogen and solid carbon. Recently, TDM has been studied by several authors as an alternative for producing hydrogen free from emissions of polluting gases such as CO2. In addition to H2, the carbon generated has commercial applications, being a value-added product of the reaction. By varying the process conditions, different types of carbon can be obtained, with different purities and conformations. Among the most valuable are carbon nano fibers. In this work, a bibliographical survey of existing methods for carrying out the thermal decomposition of methane was carried out. A thermal and homogeneous process was simulated in Aspen Plus, considering a daily production of 2.5 tons of hydrogen and 8.4 tons of solid carbon, the main process equipment is a reactor, a cyclone, a PSA-type separation column and a filter. A sensitivity analysis was carried out by varying the pressure and temperature of the reactor, the results showed that by increasing the temperature and decreasing the pressure, methane conversion increases. After the simulation, an economic analysis was carried out, the CAPEX for the simulated process is US$ 3,163,801.00 and the OPEX is US$ 6,934,660.00 per year, while the sale of the products generated is US$ 19,564 ,000.00 per year. After analysis, the process proved to be viable from an economic point of view.

    Violence against women and racism are extremely important issues that must be addressed with great care and seriousness. In this work, they will be presented together: the violent deaths of white and black women and their differences in the state of São Paulo, where the Federal University of São Carlos is located. Through Generalized Linear Models of Poisson distribution, the evolution of the number of violent deaths of women in four different periods will be studied: before the enactment of the Maria da Penha Law; from the enactment of the Maria da Penha Law to the enactment of the Femicide Law; from the enactment of the Femicide Law to the decree of the Covid-19 pandemic; and the Covid-19 pandemic decree until the end of 2021. In addition to the influence of the enactment of laws and the Covid-19 Pandemic, other factors such as Schooling, Marital Status, Age and Place of Occurrence of death will also be studied, and how these factors separately influence, and in each period, the violent death of Black and White women in the state of São Paulo from 1999 to 2021.

    Exposure to the sun is beneficial to the health of human beings as long as the necessary precautions are taken, such as correct photoprotection, since unlight induces the production of D vitamin. Despite this, ultraviolet radiation can cause damage to DNA, chemical changes and histological in epidermal cells, immunosuppression, cataracts, premature aging, and other diseases. Photoprotection is an essential tool that prevents these and other harmful effects on health. For this reason, the population's awareness of the risks arising from exposure to the sun is growing and, following this trend, the market is offering its answers. With the aim of offering better products that meet the population's demand, offering affordable prices and quality, the segment requires improvement of formulations and improvement in the quality of raw materials, which in turn, impact the development of more efficient production processes and, consequently, the need for investment in R&D. Therefore, the objective of the work is to evaluate the stages of production of mineral sunscreen in a medium-sized company that serves the master sector, as well as the marketing aspects and legislation involved in launching the product on the market. The production of mineral sunscreens is therefore a complex process that involves several steps, from the choice of ingredients to the final packaging of the product. Companies that want to stand out in this market need to be aware of consumer demands, sanitary regulations, and technological innovations. Thus, companies can guarantee the quality of their products, increase their competitiveness, and achieve success in this promising market.

    The growing demand for energy, coupled with the search for sustainable alternatives to fossil fuels, has put the sugar-energy industry at the center of discussions on economic and environmental development. The production of sugar and ethanol from sugar cane offers significant opportunities for reducing greenhouse gas (GHG) emissions and mitigating climate change. This industry plays a key role in the Brazilian economy, contributing significantly to job creation and export earnings. However, it is also associated with a number of adverse environmental impacts, including water pollution, soil manipulation, emissions of polluting gases into the atmosphere - such as carbon dioxide (CO2) - and the intensive consumption of natural resources. Proper management of these environmental risks is essential not only to comply with environmental regulations, but also to maintain sustainability of the industry and its social license to operate. Thus, this paper explores the topic of environmental risk management in sugar-energy plants, analyzing the challenges, strategies and practices associated with minimizing negative impacts on the environment. The object of study was a Sugar-Energy Plant X located in the interior of São Paulo and the visit made for the work took place in October 2023 during the 2023/2024 harvest. The Interaction Matrix method was used to identify and classify environmental aspects and risks using criteria that assess the occurrence of the event, the severity and the degree of detection. severity and degree of detection. The results showed that the sugar-energy plant has a high level of detection of the environmental risks that may occur, showing that it has ample capacity and speed to adopt measures to reduce pollution of water, the atmosphere and the soil, as well as making conscious use of natural resources in its processes. A environmental risk analysis proved to be satisfactory for the process analyzed, mainly through the application of the Interaction Matrix method.

    Given the current scenario of energy transition, biolubricants are an interesting alternative to replace lubricating oils from fossil sources, which are the most used in the market to reduce friction effects between surfaces, among other several applications Biolubricants are composed of fatty acid esters that can be derived from biomass, such as vegetable oils, from transesterification reactions of oils or esterification of fatty acids with long linear and/or branched-chain alcohols. This work aimed at evaluating the enzymatic production of fatty acid esters for biolubricant bases by esterification of commercial fatty acids and isoamyl alcohol using as a biocatalyst a liquid lipase formulation from Novozymes A/S, Eversa Transform®, which was specially formulated to product biodiesel from lipid material with high free acidity. From experimental data of ester yield or substrate conversion over time, as well as data reported in the literature for the synthesis of esters from fatty acids and DDOS (distillate from the deodorization of soybean oil), kinetic modeling were made to determine which models best fit this type of reaction (classic Michaelis-Mentem, Michaelis-Menten with inhibition, Ping Pong Bi-Bi, etc.), thus allowing the obtaining of kinetic (such as Vmax, Km, KI) and thermodynamic (enthalpy and activation energy) parameters. Also, the specificity of the enzyme for different fatty acids was determined, evaluating its affinity in relation to chain size and the presence of unsaturations, showing best results regarding to fatty acids of saturated medium-to-long chains, such as stearic acid. Regarding the solvent used, heptane proved to be more adequate. Conversion profiles over time using lauric acid (C12:0) and coconut oil (mostly composed of ca. 70% of medium-chain saturated fatty acids – C12:0-C16:0) were also evaluated. For lauric acid, a higher conversion was observed in the interval of 12 to 24 h, reaching a maximum conversion of 45%. For coconut oil, the yield of isoamyl esters was evaluated, obtaining a yield lower than 3.5% at the end of 24 h of reaction.

    Models that estimate the resulting viscosity of blending fluids have been studied for centuries and were the object of study in this work. To work with the combination of fluids, mineral base oils, synthetic base oils, a viscosity index improving additive and fourteen lubricating oils were used, seven of which were of mineral origin and the other seven were of synthetic origin. The method used was divided into two stages, the first of them was the addition of the additive to the lubricants, in seven concentrations that varied between 0.5% and 9.5% m/m. After that, the density, dynamic and kinematic viscosity were measured, all of them at 100 °C, and these experimental values were compared with the theoretical values calculated for thirteen different viscosity blending models. Then, the mean absolute error, the root mean square error and the mean absolute percentage error were calculated to verify the model with the best performance. The second stage is similar to the first, but this time, instead of adding the additive, synthetic base oils were added to synthetic lubricants and mineral base oils were added to mineral lubricants. After carrying out measurements and calculations, it was found that there was no model with better performance than another when adding base oils to lubricants, due to the high deviation values found. However, the Arrhenius, Power law and Grunberg-Nissan models were the best in predicting viscosity when viscosity index improving additives were added to lubricating oils.

    The theme of hunger gained prominence in the 20th century, leading to the establishment of the food and agriculture organization of the united nations due to the need to ensure access to food. In brazil, the adherence to initiatives such as food and nutritional security solidified after global discussions and the implementation of the zero hunger program, focusing on family farming, agrarian reform, and supply policies, including the minimum price guarantee policy. The minimum price guarantee policy, established in 2003 after the opening of the foreign market, seeks to balance prices and public stocks to ensure sovereignty and price regularization, playing a crucial role in food security. However, the disparity between the prices paid to producers and those practiced in the market affects its effectiveness. The COVID-19 pandemic accentuated price increases, impacting the basic basket, highlighting the importance of income guaranteed to producers by the minimum price guarantee policy for economic stability. When minimum prices are not balanced, they affect production costs, discouraging farmers and compromising supply, impacting food security. The Minimum Price Guarantee Policy, despite being one of the policies for public supply, is insufficient in the country's stocks, essential to promoting food security. Encouraging sustainable agricultural practices and ensuring fair access to food are goals aimed at mitigating food insecurity and its social impacts, with a planned approach to creating resilient systems in the face of challenges such as economic crises and climate change. The study addressed fluctuations in the market prices of essential products in the Brazilian basic basket from 2019 to 2022, assessing the effectiveness of the Minimum Price Guarantee Policy in mitigating impacts on producers' income and family consumption. Using descriptive and exploratory analyses, it revealed discrepancies between the prices received by producers and those practiced in the markets, highlighting government neglect and the decline in CONAB's activities over time. The lack of investment in the strategic food reserve exposes the State's fragility, indicating the need for more comprehensive policies to ensure economic stability and adequate access to basic foods, especially in times of crisis such as the pandemic. It is concluded that strategies such as the minimum price policy have been abandoned, resulting in the rise of market prices, evidencing the state's omission in fulfilling the human right to adequate food. the study suggests the urgency of reflections and debates to develop more effective food management strategies.

    Students with Autistim Spectrum Disorder (ASD) often face a series of challenges when entering higher education. These challenges may include difficulties in social interaction and communication, making relationships with colleagues and teachers more complex. The need for consistent and predictable routines can conflict with the flexibility required by university life, which can be challenging for these students. Adapting to different teaching methods, evaluations and course structures can also represent significant obstacles, requiring more personalized support and adapted teaching strategies to ensure the academic success of these students. The objective of this work, as an experience report, was to analyze and describe the experience of accompanying a student with ASD in higher education. Through the autobiographical approach, a detailed analysis of the experiences of a student with ASD was performed when facing higher education during the transition to the remote teaching period, offering a unique view of this new structure, identifying barriers in Access to education, issues of social interaction, adaptation to online teaching methods and the effectiveness of the support offered by the university institution. The study highlights the interaction of the researcher with higher education teachers, challenging the previous perspective that collaborative education would not be applicable in an undergraduate course. This interaction not only refuted this belief, but also opened doors for opportunities for mutual learning, knowledge sharing and improvement of teaching practices. By revealing the viability and benefits of collaborative education in the context of higher education for students with ASD, this work not only offers a personal account, but also contributes to the broader understanding of the importance of the right to academic education of these students. In addition, practical recommendations are presented to improve the educational experience of tea students in the remote context.

    Obtaining reliable values for bed voidage is a crucial step in the design of fluidized beds. In this work, we studied different experimental methods for determination of a liquid-solid fluidized bed voidage. Four groups of particles with different properties were fluidized in water using laboratory-scale fluidization equipment. We obtained experimental values of bed voidage (𝜀) as a function of liquid superficial velocity (𝑈) using three different techniques. The first one uses a differential pressure sensor for obtaining the vertical pressure gradient (𝑑𝑃/𝑑𝑧) and relating it to the voidage using the force balance. The second one consists of visually obtaining the average bed height (𝐻) and relating it to the voidage using the definition of voidage and the bed volume. The third technique, developed in this work, consists in using a light-emitting diode (LED) and a LDR light sensor on the outside of the column, for determining the bed height with more precision and reproducibility. The luminosity profiles around the bed’s surface had a sigmoid shape, as expected. We could find the bed’s height with less than 5 mm difference between measurements. The voidage values obtained by the three techniques were remarkably similar, specially between the two techniques based on the bed’s height. We observed the biggest differences for smaller superficial velocities, showing that the methods have better agreement in less dense beds. The laser method was more precise than the visual method, with standard deviation being seven times smaller. The experimental curves agreed with Richardson-Zaki model. The values of parameters n and k showed that the two methods based on bed height are closer to the bed behavior reported in literature.
