In the popular comunas located on the hillsides of Medellín (Colombia), the self-construction of territory coexists with food insecurity, land-use disputes, and recurring risks, while also sustaining dense organizational networks. From a perspective situated in the Global South, this research examines how urban agriculture consolidates and to what extent it strengthens social cohesion and collective action, beyond a strictly productivist framing. The study focuses on practices and organizational processes linked to family and community gardens in Medellín’s Northeastern Urban–Rural Edge (BUR NOR), drawing on the Agroecological Multitudes approach (Giraldo, 2022) to analyze articulations across environmental/territorial, social/organizational, and political dimensions. Methodologically, the research adopts Participatory Action Research, combining semi-structured interviews, focus groups, participant observation, and documentary analysis. The findings indicate that urban and popular agroecology operates as a strategy for territorial defense, generating networks of solidarity and political advocacy. Its hybrid character becomes evident (between reterritorialized ruralities and urban dynamics, and between community autonomy and institutional dependence) reinforcing the centrality of community organization for its continuity.

Primary Health Care (PHC) in Brazil underwent a structural change in its financing model in 2019. The Previne Brasil Program (PPB in portuguese), established by Ordinance GM/MS No. 2,979/2019, introduced significant changes in the way resources are allocated and impacted the organization of health work. This study aimed to understand the effects of this change on the work of health professionals, focusing on the contradictions and ideological elements that permeate this experience. This is a qualitative, descriptive, and analytical study, conducted through a narrative review compared with the legal framework on the subject, discursive analysis of interviews with management-level workers and thematic analysis of interviews with frontline care workers who had professional experiences before and after the implementation of PPB. Results show a historical context of underfunding of the Brazilian Unified Health System (SUS in portuguese) particularly of PHC, which, captured by a discourse of efficiency and cost containment, finds in PPB one of its main milestones for implementation. Analysis of the statements made by management-level workers confirmed criticisms of the model, even as these statements operationalized an administrative and managerialist discourse. Furthermore, analysis of interviews with frontline care workers revealed an intensification of pressure in the workplace, reduced time allocated to consultation, impairments in the quality of care, and the weakening of collective spaces, all associated with the centrality of quantitative targets and the managerial logic introduced by the new financing model. Thus, the PPB (Basic Planning Program) operates as a political-institutional device that reorganizes work processes, affecting professional autonomy, territorial ties, and workers’ mental health. It is concluded that ethical-political suffering expresses structural processes of exclusion linked to the institutional reorganization of Primary Health Care, jeopardizing fundamental principles of SUS, such as comprehensiveness, longitudinality, and equity.

Youth climate activism typically emphasizes global protests, yet institutional models in the Global South remain underexplored. Here we analyze the Young Environmental Ambassadors program in São Carlos, Brazil, where elected high-school students operationalize environmental democracy's three pillars (information, participation, justice) through MPSP facilitated hearings on nature-based solutions (NbS). Questionnaire data (n = 10), interviews (n = 5), and observations (n = 12 meetings) reveal curriculum-aligned training informed council elections and hearings addressing Espraiado Stream water governance, Bicão Park greenspace protection, and Cidade Aracy waste management, yielding Municipal Law 21.458/2023. Prosecutorial facilitation in affected schools positioned youth as community-state mediators, preventing radicalization via institutional channels. This scalable triad integration offers Global South municipalities a replicable NbS governance model, building long-term climate resilience absent in transnational protest frameworks.

Danzadiar el fin: un manifiesto encarnado para la salud mental universitaria nace de la insistencia en danzar cuando el mundo universitario —y el mundo humano— insiste en caer. Se trata de una investigación que se mueve entre creación y sensibilidad, entre culturas tradicionales populares y reinvención de lo vivo, afirmando el movimiento como gesto sensible, afectivo, colectivo y de cuidado. En el atravesamiento de las presiones productivistas y utilitarias, así como de los silenciamientos que marcan la experiencia en un mundo homogéneo y hegemónico, el trabajo afirma el cuerpo como territorio donde la vida aún puede pulsar. Con el objetivo general de cartografiar procesos de invención y reinvención del cuidado en salud mental en el contexto universitario, mediante prácticas corporales sensibles, el texto convoca a la universidad a sentir, tornándose crítica y cuidadosa. Se trata de una investigación cualitativa, de enfoque cartográfico, que utiliza como procedimientos de producción de datos las artes del cuerpo, especialmente los dispositivos provenientes del Teatro Ritual (Grupo Arkhétypos) y del Método Bailarín-Investigador-Intérprete (BPI). Los resultados señalan tres ejes temáticos de la diferencia para la construcción de una universidad en su potencia de resistencia y reinvención: (1) cuerpo, afecto y cuidado: la producción de sí-mundo como vida encarnada; (2) micropolíticas de reactivación de la vida: juego, tiempo otro y deseo; (3) vida relacional: colectivo, ancestralidad y ecología sensible. Se concluye que el acto de cuidar se constituye en la disponibilidad de hacer pulsar al otro, produciendo desplazamientos ético-estético-político-sensibles-críticos con/por/a partir de las pistas: cuerpo-territorio-red-ecología-afecto, cuerpo-ancestralidad, cuerpo-juego, cuerpo-fiesta y cuerpo-amor. Por lo tanto, danzadiar el fin no anuncia un término, sino un gesto de travesía: danzar el fin como quien prepara comienzos y sostiene, en el espacio universitario, la pulsación de la vida.

Mobile robotics has gained prominence in the industry, especially through the use of AGVs (Automated Guided Vehicles), which contribute to greater efficiency and safety in production processes. To ensure accurate line-following behavior, AGVs rely on controllers, with the PID (Proportional, Integral, and Derivative) being the most commonly used due to its simplicity and effectiveness. This work presents the development of a control systems platform applied to a line-following AGV project. The platform enables the implementation and testing of functionalities, while also ensuring project continuity through a standardized documentation model consisting of seven technical documents and a well-defined software architecture. Practical experiments with the AGV using the PID controller demonstrated proper system operation and validated the platform as an effective tool for preserving project legacy and supporting future enhancements.

Reading is an important skill for the personal and social development of the individual. The present study aims to evaluate the effects of Teaching Module 3 – Reading Comprehension of Texts, from the teaching program Learning to Read and Write in Small Steps (ALEPP in Portuguese), on students with reading comprehension difficulties, as well as the effect of this teaching procedure on school tests in Portuguese Language and the application of a social validity questionnaire with teachers and students. For this, two studies were conducted. In both studies, an assessment of word reading skills and text comprehension was employed before and after the teaching procedure, along with a social validity questionnaire administered to students and teachers. In Study 2, the participants’ Portuguese Language school tests were also monitored. In the first study, ten 2nd grade Elementary School I students with difficulties in reading comprehension participated and did Module 3. The data were analyzed individually, and statistical analyses were conducted comparing pre-test and post-test results. In the second study, fourteen 3rd grade Elementary School I students with reading comprehension difficulties participated. They were divided into an Intervention Group (IG), which completed teaching procedure, Module 3, and a Comparison Group (CG), which engaged in reading children’s books. This design was chosen to verify the effect of Module 3 in comparison with another teaching procedure. The assessment instruments used in this study were the same as those in the first study, and the data were statistically analyzed. The results of both studies indicated that Module 3 was effective for teaching reading comprehension, and, in the social validity questionnaire, teachers and students evaluated the research positively and reported academic contributions. In Study 1, a statistically significant difference was found when comparing the pre-test and post-test results of ACoLE 3. In Study 2, within the intervention group, a statistically significant difference was found when comparing the initial test results with the final and maintenance tests of ACoLE 3. Furthermore, in Study 2, within the comparison group, a statistically significant difference was also found when comparing the initial test results with the intermediate, final, and maintenance tests. Regarding the comparison between groups in Study 2, no statistically significant difference was found. In Study 2, about the performance of the groups in Portuguese Language school tests, no statistically significant difference was found between the groups, nor within the comparison group across the school tests. Unlike the intervention group, in which a significant difference was found when comparing the fourth school test results with those of the second and third school tests, suggesting an improvement in student performance in the fourth school test, possibly due to the contribution of teaching procedure, Module 3. However, in the present research, one limitation is the small sample size, and another limitation is that some participants engaged in extracurricular activities offered by the school, which may also have an important role in improving participants’ performance. It is suggested that future studies conduct the intervention with a larger sample of participants and with greater experimental control of variables.

Microplastics (MPs) are persistent and widely distributed environmental contaminants, whose presence has been increasingly recorded in terrestrial environments. This study aimed to determine the occurrence, distribution, and characterization of MPs in different compartments of the terrestrial environment, including compost products, urban soil aggregates, and coastal sediments. To this end, density separation, organic matter digestion, and visual characterization techniques were used to identify the particles in terms of abundance, shape, color, and size. The results showed the presence of MPs in all compartments analyzed. In compost products, MPs were identified in both the pre- and post maturation stages, at a ratio of 3933 MPs/kg, with a predominance of fibers and wide morphological diversity, indicating that the composting process is not capable of completely eliminating these contaminants. In urban soil aggregates, we obtained an abundance corresponding to 10,283 MPs/kg, with a higher concentration of MPs in water-stable aggregates, especially in the larger fractions, suggesting direct interaction of these contaminants with the soil structure and possible influence on its stability. In coastal sediments, MPs showed variable distribution along the vertical profile, with an average of 11,594.67 ± 9,227.647 MPs/kg, reinforcing the role of sediments as compartments for accumulation and environmental recording of contamination. The results demonstrate that MPs are widely distributed in terrestrial systems, highlighting the need for effective waste management and plastic contamination mitigation strategies.

This dissertation investigated intimate partner violence (IPV) in relationships among gay men in Brazil, integrating two complementary studies: a cross-sectional quantitative survey aimed at characterizing IPV and examining its associations with minority stress indicators, and a second study focused on assessing the feasibility of a remote secondary prevention intervention using a mixed methods approach. The first study included 60 adult gay men living in Brazil (Mage = 35 years), most of whom were cisgender and from the Southeast region. The Revised Conflict Tactics Scale (CTS-2) and the Minority Stress Protocol were used to assess internalized homonegativity, sexual orientation disclosure, and experiences of stigma. Descriptive and correlational analyses were conducted. A high prevalence of IPV involvement in the past year was observed, with 80% reporting victimization and 63.33% reporting perpetration. Psychological violence was the most frequent form, followed by sexual and physical violence. Strong bidirectionality was observed in relationship dynamics. Experiences of stigma showed more consistent associations with different forms of IPV, whereas internalized homonegativity and sexual orientation disclosure were not directly associated with this outcome. The second study, using a quasi-experimental mixed-methods design, involved the development, implementation, and feasibility evaluation of a remote group-based intervention. Guided by Bowen et al.'s (2009) feasibility framework, the study assessed acceptability, implementation, and practicality. The intervention consisted of synchronous online group meetings and asynchronous activities addressing IPV recognition, minority stress, emotional regulation, and assertive communication. Exploratory quantitative indicators and qualitative data (field notes and participant reports) were analyzed in an integrated manner. Findings indicated satisfactory levels of acceptability and feasibility, with recommendations for increasing the number of sessions. By integrating national prevalence estimates with the evaluation of an affirmative intervention proposal, this dissertation contributes to the advancement of preventive strategies that are sensitive to the psychosocial and contextual specificities shaping intimate relationships among gay men in Brazil.

This research addresses performance measurement in the purchasing process of multinational companies, focusing on the use of dashboards as a decision-making support tool. The study aims to develop a prototype dashboard for the purchasing process capable of meeting the informational needs of decision-makers at the operational, tactical, and strategic levels. To achieve this objective, a quantitative approach and the Design Science Research method were adopted, guiding the development of the dashboard prototype so that it is applicable to the organizational reality of the analysis unit, a multinational company in the cutting and welding segment. The literature review analyzes the themes of performance measurement, the purchasing function in the supply chain, and the relationship between performance measurement in purchasing and the use of dashboards, understanding the needs of different purchasing decision-makers. As main results of the literature review, 68 indicators applicable to the purchasing process were identified, as well as literature that supported the prioritization of these indicators considering key characteristics and, subsequently, their classification at the operational, tactical, and strategic levels. Data collection involved mapping tables in the ERP (Enterprise Resource Planning) system of the analysis unit, SQL (Structured Query Language) queries, and DAX calculations in Power BI. The developed prototype increased information transparency, promoting decisions such as direct interaction with suppliers to mitigate supply risks, developing new suppliers, or even prioritizing resources based on financial results guided by data related to the purchasing process and extracted directly from the analysis unit's ERP system. The research demonstrates that well-structured dashboards tailored to user needs improve the organization's decision-making process, enabling the migration from a reactive and manual management model to a proactive and data-driven approach, fundamental for competitiveness in global supply chains. For future studies, it is recommended to increase the concentration of data in the ERP and create impartial evaluation checklists when the researcher is immersed in the analysis unit.

Old age is understood as a subjective marker that can generate anguish due to its association with death. As a complex social phenomenon, aging requires intersectoral policies, such as the National Social Assistance Policy, which promotes community and family interaction. This study aimed to understand the perception of aging, family bonds, memory, and digital sociability among elderly individuals attending community coexistence services in Piracicaba (SP). The following data collection methods were used: (a) a sociodemographic questionnaire, (b) a semi-structured clinical interview guide, and (c) an association diary. Through an exploratory, descriptive, and qualitative approach, 86 elderly individuals were interviewed (87% women, average age of 69 years). The participants, mostly retired with low education and income levels, showed an expanded concept of family, including affective bonds with relatives, neighbors, and even pets. Memory was valued as a testimony of life and as a bonding element. Internet use was seen mainly as a pastime, not as a community space. The body emerged as a central theme, marked by the duality between health and chronic pain. The birth of grandchildren and the independence of children were perceived as positive aspects, although feelings of abandonment were reported as negative experiences. Notably, the elderly did not spontaneously address the topic of aging and did not identify with their own age. The study concludes that public policies for old age must consider its subjective and relational dimensions, going beyond traditional approaches to effectively embrace the concrete experiences of the elderly.

Behavioral flexibility, the ability to rapidly adapt behavior to changes in the environment, is a central component of cognitive functioning and is frequently impaired in neurological and psychiatric conditions. Investigating its neural bases aims to broaden its understanding and improve therapeutic interventions. The set-shifting task is widely used to assess behavioral flexibility, examining the ability to adjust behavior in response to dynamic environmental demands. Among the factors influencing this ability, serotonin plays an important role, particularly via 5-HT2C receptors. Meta-chlorophenylpiperazine (mCPP), a non-selective serotonergic agonist with high affinity for 5-HT2C receptors, has been frequently employed in research; however, its influence on set-shifting performance had not yet been explored. The present study investigated the effects of different doses of mCPP (0; 0.5; 1; 2 mg/kg) on the behavioral flexibility of adult male and female Wistar rats, aiming to characterize potential sex differences and their pharmacological modulation. As expected, mCPP impaired behavioral flexibility in both males and females, albeit with a complex and sexually dimorphic pattern of effects. In males, the main effects occurred at 0.5 mg/kg dose, which reduced accuracy and increased omissions and perseverative errors. Females showed greater sensitivity to the 2.0 mg/kg dose, with impairments characterized by increased reaction time and omissions, without reduced accuracy. Baseline sex differences were observed, suggesting greater task flexibility in males, a pattern that persisted following mCPP treatment. Taken together, the results indicate that mCPP reduces behavioral flexibility, differentially affecting performance in males and females, with implications for understanding sex differences in psychiatric conditions characterized by behavioral inflexibility.

Digital communication in Graduate Programs (PPGs) at public universities plays a fundamental role in transparency, visibility, and accountability, especially within the evaluation framework of the Coordination for the Improvement of Higher Education Personnel (CAPES). However, gaps persist in the institutionalization of this work, evidenced by the lack of guidelines, workflows, and training to support the production and publication of content with regulatory compliance, including accessibility, personal data protection, and copyright. In this context, this study analyzes the organization of digital media management practices in the PPGs of the Center for Education and Human Sciences (CECH) at the Federal University of São Carlos (UFSCar). The general objective is to propose guidelines and recommendations to improve the management of these media, integrating process management tools. This is a qualitative, exploratory, and applied study, based on a literature review, document analysis, and the application of an online questionnaire. The sample included all 12 PPGs at CECH/UFSCar. In the documentary stage, publications from the “News” section of institutional websites were analyzed for the period from 2017 to 2025. The questionnaire obtained responses from 10 programs, and a descriptive analysis of Instagram profiles was also conducted for the period from November 1, 2024, to October 31, 2025. Data were analyzed through thematic classification and process management tools, such as Check Sheets, Pareto Diagrams, the GUT Matrix, 5W1H, and the Five Whys. The study was approved by the Research Ethics Committee of UFSCar (Approval No. 7,896,089). The results indicate a predominance of administrative-informational content, an irregular presence of science communication, and the central role of administrative staff in day-to-day updates, without formal training and with low standardization of workflows. It is concluded that digital management is sustained by local and reactive efforts. The study proposes the institutionalization of integrated guidelines, the provision of continuous training, and the development of institutional support instruments to improve digital communication and reduce regulatory risks.

Environmental Education has been the subject of research and legislation due to the importance and scope of environmental issues. It is a fact that the environment has become a global concern, whether due to climate change and extreme events, deforestation and pollution, among other factors. Since 1997, through the National Curriculum Parameters (PCN), the environment has been addressed in the classroom as a cross-cutting theme. From that period onward, legislation related to the topic has been updated, and Environmental Education has gradually gained prominence and recognition. In this context, understanding how teachers perceive the environment and how they incorporate Environmental Education topics into their classes is of vital importance for advancing toward a more environmentally responsible society, committed to environmental issues and socio-environmental justice. This project proposed a study with teachers from the municipal school system of Capivari (SP), using interviews, questionnaires, and documentary research, in order to investigate their environmental perceptions, how they develop environmental themes in the classroom, and how public authorities could contribute to this process. The research has a qualitative approach, and data analysis was carried out using Content Analysis, according to Bardin.

The purpose of this dissertation is to investigate mourning from a Freudian perspective, in articulation with contemporary culture, with a focus on the dimension of temporality. This is a theoretical study grounded in psychoanalytic theory. The first chapter addresses the status of mourning in Freud, discussing its metapsychology, the notion of the work of mourning, its main clinical signs, and the question of its termination. The second chapter examines the effects elicited by loss, particularly in the intrapsychic domain and its clinical developments, considering different modes of reaction to object loss that may hinder or prevent the accomplishment of the work of mourning. The third and final chapter proposes an articulation between mourning, temporality, and contemporary culture, prioritizing the relationship between the mourning subject and time. From this perspective, it is understood that the task of mourning takes place at the intersection of the individual and the collective, articulating intrapsychic, intersubjective, and social dimensions. It is observed that the temporality of mourning, which is explicitly subjective, appears antagonistic to the prevailing modes of relating to time in contemporary culture, marked by speed and urgency. The hypothesis advanced is that, in the present context, there is a temporal impasse between the accelerated time promoted by culture and the subject’s subjective temporality. Thus, the time offered to the subject may function as an obstacle to the temporal movement required by mourning, hindering the work of working-through and symbolization in the face of loss.

This dissertation aims to examine the notion of reality in Freud’s thought, starting from the observation that, although ubiquitous, it is mostly mobilized in a functional manner, without a systematic conceptualization. The problem consists in determining how the real manifests itself when it does not lend itself to explicit thematization, remaining as a presupposition that operates between the lines of the texts, in clinical technique, and at the point of contact between distinct epistemological planes. Our temporal delimitation follows the itinerary extending from Freud’s Parisian stay under Charcot (1885-1886) to the psychopathological writings and the supposed abandonment of the seduction theory, around 1897. From a methodological standpoint, we adopt a historical-conceptual investigation that integrates internal analyses of Freudian production with external reconstructions of the scientific context. On this basis, we select as the main axes of analysis: hysteria and neurosis in the fin-de-siècle; the controversies between the schools of hypnotism (Salpêtrière–Nancy); Freud’s experiences and productions with respect to hypnosis; his conceptions as developed from the monograph on aphasias and other contemporary works related to the clinic and to hysteria; the relation of supplementarity between Studies on Hysteria (1895) and the Project for a Psychology (1895); and, finally, the psychopathology of the neuropsychoses of defence and the seduction theory. The results indicate a bivalence between Realität and Wirklichkeit: on the one hand, reality as factuality and given content; on the other, effectiveness as that which acts and produces effects. On the basis of this distinction, we circumscribe differentiated domains of reality — psychic, external, and clinical — and propose the notion of psychic effectiveness, discernible in symptom formation and in dream-work. Moreover, we recognize other genres of expression of the real, such as the effet de réel produced by Freudian clinical writing and the “temporalities of the real” inferred from the ontogenetic series deduced in the Project, within which reality is progressively constituted in the organism through conflict between the internal and the external. We conclude that it is possible to delimit expressions of the real in the Freudian oeuvre, whether in the encounter between epistemological planes (reality thought from the Project and from Aphasias), or in specific works or periods, such as the problem of reality in the first psychopathological conceptions or in the seduction theory.

Considering that the concept of area is present in both Geography and Mathematics education, it may be regarded as interdisciplinary within the context of Basic Education. The general objective of the research presented in this dissertation was to analyze the concept of area within the context of school Geography, taking as its object the way this concept is presented in Geography textbooks. Grounded in cultural-historical theory and narrative inquiry, the study understands experience as both phenomenon and method, recognizing that the researcher and the research mutually constitute one another through the movement of narrating, analyzing, and interpreting lived experience. The research question guiding the study was: how is the interdisciplinary concept of area presented in Geography textbooks, and what implications does this approach produce in the teacher-researcher’s reflections on her teaching and learning processes? Based on this objective and question, the analysis focused on two textbook collections and on the production of narratives of teaching experience. Methodologically, the research adopts a qualitative approach organized into four analytical categories: (1) the approach to the concept of area in textbooks; (2) reading space, graphic representations, and the confusion between area and territory in textbooks; (3) proposed activities and the mediation of knowledge; and (4) in interdisciplinarity with Mathematics, the concept of area becomes a movement of thought which, at the stage of synthesis, comes to compose an interpretative unity guided by historical-dialectical logic. The results show that, although recurrent, the concept of area appears in textbooks in a fragmented way, marked by silences and reductions that compromise its logical-historical meaning, often being treated as a technical procedure devoid of conceptual mediation. The narratives of the teacher-researcher reveal that this limiting form of approach directly interferes with pedagogical practice, requiring teaching interventions so that the concept acquires meaning and becomes constituted as an instrument of thought. Furthermore, it becomes evident that interdisciplinarity between Geography and Mathematics is not realized in textbooks as an effective articulation, but rather as a juxtaposition, which limits the understanding of area in its relationship with lived space. The central thesis defended is that the interdisciplinary articulation between Geography and Mathematics, guided by historical-dialectical logic, enhances the teaching of the concept of area by overcoming its technical reductionism, enabling narratives of experience to be translated into analytical elements supported by a consistent theoretical and methodological structure. It is concluded that teaching the concept of area implies fostering theoretical thinking capable of understanding space in its materiality, historicity, and social meaning, integrating calculation, territory, and experience.

Single nucleotide polymorphisms (SNPs) represent the most common form of genetic variation in the human genome and have been extensively studied due to their impact on phenotypic traits and susceptibility to complex diseases. Although genome-wide association studies (GWAS) have yielded important discoveries by testing each SNP marginally, this approach tends to overlook dependencies between loci, a phenomenon known as epistasis, which may leave part of the phenotypic genetic variance unexplained. To address this limitation, the present work proposes a two-step approach for identifying SNP–SNP interactions associated with blood glucose levels (mg/dL). In the first step, simple linear regression models are fitted to pre-select SNPs with the strongest evidence of marginal association with the phenotype. In the second step, Interaction Forests are applied to the selected subset to rank SNP pairs according to their interaction effect, as quantified by the Effect Importance Measure (EIM). Prioritized pairs are subsequently validated using linear regression models with interaction terms. Missing SNPs were imputed using Markov chains and recombination fractions, and the data were obtained from the ISA-Capital study, comprising 698 genotyped participants and 324,471 SNPs after quality control. Simulation results demonstrated that Interaction Forests consistently recovered pairs with artificially introduced interactions under both quantitative and qualitative scenarios. In the application to real data, the regression-based pre-selection strategy (Case 3) yielded the lowest interaction p-values among the three approaches evaluated, with pairs reaching p < 10^-15, and enabled the construction of SNP interaction networks with connected components and identifiable cycles. These findings reinforce the potential of the proposed methodology for detecting epistasis in high-dimensional genomic data.

The production of ethanol from lignocellulosic biomass, such as sugarcane straw, requires the inclusion of additional process steps to release the sugars (monomers, glucose and xylose) that will later be converted into ethanol via the fermentative pathway. The first of these two steps, known as the pretreatment step, promotes the disruption of the cell wall, reducing biomass recalcitrance through the removal or modification of lignin, an increase in surface area and porosity, as well as a decrease in cellulose crystallinity. These modifications aim to make cellulose and hemicellulose more accessible to the enzymes used in the second step of the process, enzymatic hydrolysis. The objective of this work was to implement, in the Scilab software, phenomenological mathematical models that could describe the hydrothermal pretreatment and enzymatic hydrolysis steps of sugarcane straw. Once the temperature (T) and time (t) parameters for the hydrothermal pretreatment stage had been defined, linear regression models were fitted to estimate the severity factor (SF) and the mass yield (MY). Based on this information, the composition of the solid fraction of the pretreated biomass can be obtained by integrating the differential equations resulting from the mass balances of the components released from the biomass during the pretreatment process. All degradation kinetics are assumed to be first order. Subsequently, the composition of the solid fraction is used as input for the enzymatic hydrolysis model, which, once the reaction time and the concentration of the enzymatic extract are provided, estimates the composition of sugars (glucose and xylose) in the liquid fraction. The experimental data used to fit the models were obtained from experiments carried out by the research group of the Laboratory for the Development and Automation of Bioprocesses (LaDABio) and of the Laboratory of Biochemical Engineering (LEB), both in Department of Chemical Engineering, Federal University of São Carlos. According to the results of this study, splitting the cellulose and hemicellulose into reactive and non-reactive parts optimised the description of their degradation profile during pretreatment. Moreover, the graphical method produced promising results for the severity factor estimation, with relative errors of less than 5% for each condition. Regarding enzymatic hydrolysis, the simplified model more accurately characterised the experimental data than the detailed model. Taken together, the most appropriate scenario for the hydrothermal pre-treatment of sugarcane straw is operating at an isothermal temperature of 195 °C for 10 minutes.
