This dissertation comprises two interdependent chapters. In the first chapter, I carried out a systematic literature review, focusing on articles on forest restoration, ecological restoration, carbon and remote sensing up to November 2022. The systematic review was conducted using the Web of Science database. Exclusion and inclusion criteria were applied, resulting in 38 studies that were analyzed based on information such as place of publication, location of the study, type of vegetation, type of restoration, type of satellites and modeling used in the scientific articles. In the second chapter, an area undergoing restoration using the direct sowing method was monitored from 2018 to 2022, and each year the vegetation indices (NDVI, SAVI, EVI, PRI and CO2Flux) were analyzed to understand the behavior and growth of the restored vegetation in each year. At the same time, forest inventory data collected by the SemeAR/UFSCar Research Group was used. Using this data, it was possible to calculate the total biomass (t.dm/ha) and the carbon stock in the trees and in the stratum (tCO2e), establishing relationships with the vegetation indices by means of a multiple linear regression analysis using the Stepwise technique in RStudio. The main results of this work include: (i) mapping research into forest restoration, ecological restoration, carbon and remote sensing; (ii) calculating the carbon stock and biomass for the study area, restored using the direct seeding technique; and (iii) comparing the forest inventory data with the information generated by the vegetation indices, highlighting the relationship between these indices and the information on the carbon stock.

Doctors generally establish a vertical relationship with their patients, in which there are many asymmetries in the dialogue, but this socio-historical construction of asymmetries and distancing can be mitigated when the doctor brings his discourse closer to the patient, humanizing his professional practice. Medical schools can help with this through their role in training new professionals. With this in mind, this research focused on analyzing simulations of care provided virtually by medical students at a federal university in the interior of the state of São Paulo, in order to understand how students are evaluated and, based on this evaluation, how they construct their discursive styles. In order to do this, we started with French semiotics, especially the writings of Jacques Fontanille and his semiotic practices, and we used the concept of Zilberberg's tensiveness and Landowski's zoosociosemiotics. We elaborated and categorized 4 main discursive styles of doctors in training: humanized, bureaucratic, emotional and indifferent. In our analysis, we noticed a movement on the part of the university to get students to identify more with the humanized style and to understand it as conforming to the norm. We hope that this semiotic elaboration of discursive styles will enable new analyses of doctor-patient relationships, which are still lacking in studies and research in the field of linguistics.

Deforestation in the Legal Amazon region is one of the main factors generating greenhouse gas emissions. These emissions can be minimized with the efficient use of areas destined for agriculture in the region. Given this context, this study aims to measure the growth in Total Factor Productivity - TFP - based on data from the 2006 and 2017 Agricultural Censuses, Municipal Agricultural Production - PAM - and the state's Gross Domestic Product - GDP - for agriculture, all published by the Brazilian Institute of Geography and Statistics - IBGE, as well as data from the Greenhouse Gas Emissions and Removals Estimation System - SEEG. The estimates were made using the Malmquist (M) and generalized Malmquist (GM) indices, which do not take into account the generation of undesirable by-products, the Greenhouse Gases (GHGs). These indices were compared with the Malmquist-Luenberger (ML) and global Malmquist-Luenberger (GML) indices, which take into account the presence of these by-products in agricultural production. The results pointed to a growth in TFP for the Legal Amazon, both for productivity and for the change in technical efficiency and technological efficiency. However, for the GML and ML indices, which take into account the existence of by-products, growth was lower than for the M and GM indices. The results also show that in 56% of the municipalities in the Legal Amazon there is a greater productive emphasis on economic growth.

In modern times, electricity has become a vital necessity, but its use can trigger a series of problems related to improper waste disposal, often resulting in the release of harmful substances into the environment and human health. These substances include elements such as mercury and lead, which can cause neurological damage, kidney and respiratory problems. In addition, this type of improper disposal can cause serious environmental damage, polluting the soil, water, and air. In this context, the importance of implementing public policies and environmental awareness focused on proper disposal stands out. This study aimed to investigate the problems arising from improper disposal of such waste and to assess the level of understanding of the target audience regarding the concept of reverse logistics, through the application of a form. The analysis of the responses revealed a lack of overall understanding of the concept of reverse logistics and also regarding the proper disposal of fluorescent lamps by a large part of those surveyed. Thus, a proposed solution would be the implementation of environmental education programs, combined with investments in public policies, aiming to raise awareness among the population about the importance of environmentally sound disposal and to encourage them to adopt the practice of reverse logistics in a safe manner. Additionally, this study sought to elucidate the harms resulting from improper disposal and the benefits arising from reverse logistics regulated by Decree No. 10,936/2022.

In 2050 the world population will be more than 9 billion people and to meet this growing food demand it will be necessary to increase food production by at least 60%. To solve these problems, fertilizers are increasingly being used on plantations, often indiscriminately, resulting in various environmental impacts. As a possible solution to remedy or reduce environmental impacts arising from the incorrect use of fertilizers and waste of water, new technologies have emerged, among them, one of the most promising is the use of hydrogels in the soil, as some have great absorption and release properties. gradual release of water and potential to bind to various substances, enabling the controlled release of fertilizers. Therefore, this work aims at the synthesis and characterization of poly (vinyl alcohol) (PVA) hydrogels for application in rational use of water and release of NPK fertilizers in soil. The hydrogels were called HPVA and synthesized in different proportions considering the stoichiometry in moles of free OH present in PVA per mole of EDTAD, being 10:1, 20:1 and 100:1. They were characterized by Fourier transform infrared absorption spectroscopy (FTIR), scanning electron microscopy (SEM), thermogravimetry (TG) and swelling capacity. The most stable HPVA was tested for absorption and release of NPK in soil and had its biodegradation and phytotoxicity characteristics evaluated, demonstrating the capacity for controlled release of water and NPK in soil in a bean seedling plantation and not proving to be phytotoxic, in addition to being biodegradable. Therefore, HPVA demonstrated to be a promising material for rational use of water and release of fertilizers into soil.

The study aims to understand issues related to linguistic accessibility in the Portuguese language discipline for deaf students in Technological High School, within the context of remote teaching. The research involved reflections in partnership between the researchers and the dyad of the teacher and Educational Interpreter (EI) for the deaf student. The choice of collaborative reflective spiral arises from the fact that it provides conditions for knowledge construction to occur in pathways, with the principle of decision-making collectively, taking into account all participants in the research. The explicit understanding and joint consideration of pedagogical actions led each participant to review their practices. The methodological data collection procedures are organized into four spaces. Spaces 1 and 2 refer to general classes and individual sessions, conducted on the Microsoft Teams platform, while Spaces 3 and 4 relate to meetings on Google Meet among the researchers, the Portuguese language teacher, and the EI to discuss collaborative proposals. The study highlights that this perspective has led to improvements in the teaching and learning of the deaf student, particularly as Sign Language gains more prominence in reflections on teaching Portuguese as a second language. For these and other reasons, we conducted this investigation and advocate for its existence, not only as a process of training and personal/professional development for the participants but also as a project for the production of scientific knowledge and ongoing training for educators involved in the process of linguistic accessibility for deaf individuals in high school.

The introduction of Pinus spp. in Brazil, it causes a series of environmental disorders and can lead to the impoverishment of biodiversity through its invasive potential. Thinking about the difficulty of obtaining quantification and geolocation data of individuals, this work aims to compare two deep learning models for automated segmentation of Pinus spp. crowns. The comparison was carried out between a model manually trained by the Mask R-CNN algorithm (supervised classification) and an existing model, SAM (unsupervised classification). Mask R-CNN presented 81% intersection over the union of polygons and 88% overlap rate between the manually delimited Masks and the masks segmented by the algorithm, while SAM presented results of 72% and 77%, respectively. The results found reinforce the importance of studies related to new remote sensing technologies for monitoring native vegetation as a biological conservation tool.

In recent years, the wine sector has presented considerable growth, resulting in increased production and, consequently, an increase in the effluents generated during winemaking. Polyphenols stand out among the components present in these effluents due to their analgesic, antimicrobial, and antioxidant properties. However, they can become contaminants in high concentrations. Given this scenario, it is necessary to develop effective methods for recovering these substances and water reuse, emphasizing the adsorption process that permits the reuse of the adsorbed compounds. This project uses rice husks, an agribusiness waste, to obtain zeolite-based magnetic nanocomposites for chlorogenic acid (CGA) adsorption. The synthetic faujasite (FAU) zeolite was initially synthesized and modified with silane agents to optimize the interactions with the polyphenols during the adsorption process with the zeolite nanocomposites obtained from the rice husks. The adsorption tests were carried out using FAU nanostructures silanized with (3-aminopropyl) triethoxysilane (APTES), trimethylchlorosilane (TMCS), and a combination of both under mechanical agitation for 24 h. FAU:APTES:TMCS stood out, showing better performance in the adsorption of ACG (20 mg L-1) compared to FAU without functionalization, achieving removal percentages of 12.78% and 67.80% for FAU and FAU:APTES:TMCS, respectively. The zeolite optimization, using high-purity silica extracted from rice husks, was carried out by investigating the hydrothermal synthesis time to obtain the FAU phase. The FAU phase most evident was in the 18-hour synthesis period (Z18), with a surface area of 217.69 m2 g-1 and a zeta potential of -38.87 mV, indicating stability in aqueous solution. The Z18 zeolite was modified (Z18 M) with the APTES:TMCS silane mixture and used to obtain the magnetic nanocomposites. For immobilizing the zeolites obtained from rice husks, copper ferrite heat-treated at 500ºC (F500) was used due to effective magnetic properties, a lower impurity index, smaller particle sizes, and good stability in aqueous solution. In this respect, the magnetic composites Z18:F500 and Z18 M:F500 showed effective magnetic properties and element distribution along the surface evaluated by energy dispersive X-ray spectroscopy (EDS), achieving GCA adsorption rates of 31.96% and 79.53%, respectively. In this way, it is concluded that silica obtained from rice husks proved an excellent candidate for the sustainable synthesis of zeolites. The zeolite surface modification led to greater efficiency in the recovery of ACG in aqueous media. Finally, the present work presents an alternative for reusing agribusiness waste and recovering polyphenols from wine effluents, contributing to a system capable of magnetic removal in a way that favors the circular economy.

In the genus Anastrepha (Diptera: Tephritidae) of fruit flies, the fraterculus group stands out for having highly generalist species specialized in different fruits, being one of the most economically important for national and global agriculture. In general, such species are differentiated through morphological characters, however the limits of this differentiation are difficult to determine for some taxa, especially in the fraterculus species group, which presents inclusive cryptic species. This happens in some cases due to the recent separation between species, but also due to overlapping of character measurements . This phenotypic variation may even occur through the action of epigenetic factors, since these changes may be related to environmental stimuli that trigger rapid responses. This work aimed to investigate the effect of hosts fruits on populations of Anastrepha fraterculus, identifying phenotypic variations in several morphological characters present in the head, thorax, aculeus and wing, as well as investigating the presence of epigenetic marks, such as DNA methylation, between specimens that emerged from different fruits. For this purpose, flies derived from the ecosystem were used, collected from five different hosts (cherry do rio grande, pitanga, uvaia, guava and guabiroba) around the Federal University of São Carlos – São Carlos campus. Morphometric analyzes were carried out on 117 samples from the 5 fruits found, with 18 morphological characters being analyzed using the multivariate statistical method, such as principal component analysis (PCA), discriminant analysis (DFA) and Mahalanobis distance (MD). Epigenetic analyzes were investigated in a subset of these flies, using data obtained through sequencing on a MinION equipment from Oxford Nanopore Technologies of two pools of heads per fruit, which allows the study of 5mC and 6mA DNA methylation. Methylation calling at 6mA sites between flies that emerged from different fruits was done using the mCaller software and its variation between samples (DMRs) investigated by a non-parametric analysis. In turn, an analysis of differentially methylated 5mC regions (DMRs) was performed using the pycoMeth pipeline, the results of which were investigated for enrichment of gene ontological categories (GO). The morphometric results indicated phenotypic variability in morphological characters of flies from five different fruits enough to separate the vast majority of samples emerging from different fruits. Epigenetic analyzes allowed recording for the first time the presence of DNA methylation in fruit flies A. fraterculus at both cytosines (5mC) and adenines (6mA). The investigation into the distribution of these DMRs suggested important genes in the process of differentiating this species into different fruits, as well as several enriched classes of genes responsible for different functions in biological processes, including the morphogenesis of anatomical structures and the development of the nervous system. These results provide a basis for future investigations into epigenetic modifications and phenotypic variability in fruit flies, highlighting their relevance in the regulation of phenotypes, host influence and choice, and evolutionary adaptation. Understanding these adaptation patterns is crucial not only for taxonomy, but also for elucidating the evolutionary processes, and ecological dynamics, involved in the interactions between flies and their hosts.

O artigo analisa a construção e a desconstrução de capacidades estatais federais de controle do desmatamento da Amazônia brasileira por meio da abordagem dos Campos de Ação Estratégicos (CAE). Entre 2004 e 2014, o desmatamento da Amazônia teve uma queda substancial decorrente da implementação do Plano de Prevenção e Controle do Desmatamento (PPCDAm). Após uma década dessa implantação, entretanto, essa política pública exitosa passou a ser gradualmente fragilizada. Com a eleição de Bolsonaro, essa fragilização se intensificou, tornando-se um desmonte. Com base no levantamento de dados de múltiplas fontes, analisamos a dinâmica político-cultural envolvida nesse processo. A análise demonstra como a literatura sobre capacidades Estatais pode se beneficiar com o diálogo com a abordagem dos CAE. Ela também envolve uma versão única de processos históricos, favorecendo o reconhecimento da importância do PPCDAm e da destruição gerada pelo Governo Bolsonaro.

This study aims to reflect about the experiences lived by the author during her medical degree at the Federal University of São Carlos (UFSCar), correlating them with the process of identity construction from 2019 to 2024. The method used was based on the analysis of documentary records, using a qualitative approach based on Bardin's (2006) content analysis theory. The results, presented in the format of a critical-reflective narrative, highlight the importance of autonomy and emotional maturity during the initial phase of graduation, the impact of the Covid-19 pandemic on the learning process, the most significant difficulty faced during the middle years and the central role of the internship in consolidating professional identity. In conclusion, it is emphasized that identity formation during undergraduate education, according to the author, is a continuous and dynamic process, extending beyond graduation and requiring constant self-knowledge and renewal.

Este artículo investiga la interseccionais del feminismo negro y la sordera, basándose en el trabajo de Patricia Hill Collins, Bell Hooks y Kimberlé Crenshaw. Analizamos hasta qué punto las publicaciones académicas contemporáneas han representado y dado voz a mujeres que experimentan simultáneamente la identidad racial negra, el género femenino y la sordera. Discutimos cómo estas mujeres, que habitan una compleja intersección de opresiones, negocian y reexisten dentro del movimiento feminista. Utilizando la teoría de la interseccionalidad de Collins y su concepto de "pensamiento feminista negro", buscamos comprender mejor las experiencias y los desafíos de las mujeres negras sordas. El objetivo es amplificar las voces a menudo marginadas en los discursos dominantes y promover un feminismo más inclusivo e interseccional. El estudio sirve para avanzar en la comprensión de las experiencias de las mujeres negras sordas y pedir una mayor inclusión de estas voces en la literatura académica.

In Brazil, there are more than 10 million Deaf people. Of these, 2,592 Deaf people are enrolled in Higher Education institutions. This pilot study aims to explore how the field of Library and Information Science (LIS) has studied Deaf people in university libraries. This research uses a mixed methods approach: the first part of the study uses a descriptive approach to present the current state of LIS literature on Deaf users of university libraries. The second part of the research is empirical and consists of a survey that has yet to be fully carried out. It also suggests how the university library can contribute to the empowerment of the deaf community.

The project was created based on the publication of the II National Survey on Food and Nu‐ tritional Security in the Context of the COVID-19 Pandemic, published by the Brazilian Re‐ search Network on Sovereignty and Food Security. Given the published, attention was drawn to the number of people experiencing food insecurity and, specifically, in the countryside. That’s why was defined as empirical field the PDS Santa Helena, because it’s relevance in discussions of food security and sovereignty and partnership whit Solidarity Economy ac‐ tors. Were interviewed 10 farmers and 4 technicians, the social and economic demands of farmers were verified, as well their eating habits, labor conditions and how the Settlement's infrastructure helped or hindered the potential of the lots. Finally, a critical analysis of the so‐ cial vulnerabilities observed in the Santa Helena PDS was carried out and some limitations of the research were discussed.

The Riverside Community of São Carlos do Jamari is a district of Porto Velho (RO), located on the banks of the Madeira River. In February 2014, it was hit by a major flood, which left the community completely submerged for about four months, causing both material and symbolic losses. This event occurred during the same time frame as the implementation of two environmentally impactful projects: the Santo Antônio and Jirau Hydroelectric Power Plants (HPPs). The primary objective of the research was to analyze the educational processes emerging from social practice through the collective memories of this environmental disaster, by capturing oral accounts from people who experienced and continue to experience the flood. The secondary objectives were: I) to contribute to the advancement of the oral history of the 2014 flood in the lower Madeira River region; II) to clarify the ways in which Individual Memory and Collective Memory intertwine in the process of reconstructing lived experiences; III) and to identify the emotional costs of the flood, understanding what community members did during the event, what they wanted to do, and what they believed they were doing. The adopted methodology was based on memory studies, including fieldwork (2022), with a dialogical, careful, and respectful approach to popular education and culture, involving the participation of fourteen riverside residents who experienced the 2014 flood (with a diverse sample). For methodological support, a guide with Oral History Techniques was created. The data collection instruments used were semi-structured individual interviews (recorded and transcribed) and direct observations (recorded in field diaries). Through Data Analysis and the Analyzed Results, it was possible to access the collective memories of this episode, contributing to the historical record of the 2014 flood, including: the collective memories of receiving the news of the flood; the elders who had never experienced such a flood; those who remained in the community during the flood; the sheltering in schools in Porto Velho; the return to the community; their thoughts on the influence of the HPPs; the material and symbolic losses; the insecurities; the sorrows; the strategies for overcoming the flood; the “New São Carlos” Project; and finally, the collective memories of learning from the flood. From the learning process, the social practices of resistance and the fight for the (re)rooting of the São Carlos do Jamari (RO) riverside community after the flood are identified, and the educational processes revealed are related to unity, cooperation, and a sense of community in reorganizing the community by cleaning and removing the mud, so that they could not only have a place to live again, but also possess a counter-argument to compel public agencies—who had denied financial assistance to reconnect electricity, water, and other basic services—to resume operations and recognize the territory.

Many women have difficulty in activating the pelvic floor muscles (PFM). This is a concerning factor for health professionals and public government institutions, as an unhealthy PFM could be associated with the presence of PFM dysfunctions. Therefore, the aim of the study was to analyze the agreement between the perception of young women about their PFM contraction and the results of a physical assessment, according to the strength, endurance, and contraction repetitions. Method: Cross-sectional study with 43 university students between 18 to 35 years old. Examiner A filled out a semi-structured questionnaire to assess the self-perception of the ability to contract the PFM. The physical exam was performed by bidigital vaginal palpation, conducted by Examiner B blinded to the answers of the previous stage, and according to the PERFECT scheme (P = power; E = endurance; R = repetitions of item “E;” F = fast contractions). Data was assessed by the Cohenʼs linear weighted kappa (Kw). Results: The agreement between the self-perception and the physical evaluation of the PFM function presented a very poor agreement for all the items of the PERFECT scheme (P(Kw)= 0.12; E(Kw)= 0.07; R(Kw)= 0.09; F(Kw)= 0.04). Conclusion: Young women do not have sufficient knowledge about PFM contraction and function. It should concern health government and institutions, as a poor PFM awareness might increase the difficulty to identify signs and symptoms related to PFM dysfunctions and reduces demand for and adherence to PFM treatment programs

Scientific research plays a fundamental role in the health field. In this context, the practice of Evidence-Based Medicine (EBM) has become increasingly popular, proposing to integrate the best available scientific evidence into clinical practice. This concept has also been included in the curricula of medical schools, aiming to train professionals familiar with the process of seeking and critically applying scientific evidence in their healthcare practice. This topic can be approached in various ways during the course, including student participation in scientific production, for example. This graduation thesis reflects on and discusses different ways in which a medical student at the Federal University of São Carlos can engage in scientific research, based on three experiential accounts, and how this positively impacts their professional development.

The search for new metal-based anticancer drug candidates is a fundamental task in medicinal inorganic chemistry. In this work, we assessed the potential of two new Ru(II)–phosphine–mercapto complexes as potential anticancer agents. The complexes, with the formula [Ru(bipy)(dppen)(Lx)]PF6 [(1), HL1 = 2-mercapto–pyridine and (2), HL2 = 2-mercapto–pyrimidine, bipy = 2,2’-bipyridine, dppen = cis-1,2-bis(diphenylphosphino)- ethylene] were synthesized and characterized by nuclear magnetic resonance (NMR) [1H, 31P(1H), and 13C], high resolution mass spectrometry (HR-MS), cyclic voltammetry, infrared and UV-Vis spectroscopies. Complex 2 was obtained as a mixture of two isomers, 2a and 2b, respectively. The composition of these metal complexes was confirmed by elemental analysis and liquid chromatography-mass spectrometry (LC-MS). To obtain insights into their lipophilicity, their distribution coefficients between n-octanol/PBS were determined. Both complexes showed affinity mainly for the organic phase, presenting positive log P values. Also, their stability was confirmed over 48 h in different media (i.e., DMSO, PBS and cell culture medium) via HPLC, UV-Vis and 31P{1H} NMR spectroscopies. Since enzymes from the P-450 system play a crucial role in cellular detoxification and metabolism, the microsomal stability of 1, which was found to be the most interesting compound of this study, was investigated using human microsomes to verify its potential oxidation in the liver. The analyses by LC-MS and ESI-MS reveal three main metabolites, obtained by oxidation in the dppen and bipy moieties. Moreover, 1 was able to interact with human serum albumin (HSA). The cytotoxicity of the metal complexes was tested in different cancerous and non-cancerous cell lines. Complex 1 was found to be more selective than cisplatin against MDA-MB-231 breast cancer cells when compared to MCF-10A non-cancerous cells. In addition, complex 1 affects cell morphology and migration, and inhibits colony formation in MDA-MB-231 cells, making it a promising cytotoxic agent against breast cancer.

Brazil's agricultural sector has seen significant economic growth due to increased productivity, yet its greenhouse gas (GHG) emissions have risen by about 2.5% annually. This study examines Total Factor Productivity (TFP) and GHG emissions in Brazilian municipalities from 2006 to 2017. It compares standard TFP measures with those considering GHG emissions, finding lower growth and efficiency in the latter. TFP growth didn't lead to emissions reduction; 65% of municipalities didn't control emissions while improving productivity. The study also highlights the need to monitor environmental efficiency in Brazilian agriculture, a topic overlooked in existing literature.
