In applied statistics, counting data are often observed in different areas of study. Due to the great diversity of problems that result in these types of data, it is necessary to propose new models. In this work, we propose generalizations of the Skellam distribution, whose support consists of the set formed by integers (positive and negative), aiming to also explore in the context of regression models. For the process of estimating and inferring model parameters, the classical (maximum likelihood method) and Bayesian (Markov Chain Monte Carlo) approaches were considered for comparison purposes. Specifically regarding the Bayesian approach, which was more efficient in the proposals presented here, we used a variant of the Hamiltonian Monte Carlo algorithm, which consists of reformulating Hamilton’s equations by introducing a stochastic component into the gradient equation, deriving the Stochastic Gradient Hamiltonian Monte Carlo algorithm. To illustrate the proposed models, we present the analyzes of data sets referring to two real problems (3 datasets in total): In the first problem, a set of data corresponding to observations of the weekly variation of the Ibovespa score was considered, that is, the price difference, measured in ticks (cents) of the current day in relation to the previous day, in the period between January 2000 and December 2022. The estimated values for the parameter p characterized the data set as inflated with observations -2 (ticks); In the second problem, two sets of data were considered, corresponding to the values of the differences between games won and games lost by teams in the 2022-2023 regular season of the National Basketball Association, in each conference (East and West). The selection criteria indicated the k-MS model with k = −12 as the best adjusted for the Eastern conference, while for the Western conference, the indicated value was k = −38. Given the good results, both the k-MS and the k-IS models proved to be good alternatives to explain the behavior of data with integer values.

Brazil is recognized worldwide for its pioneering role in integrating ethanol into its energy matrix, produced via fermentation using yeast strains, particularly Saccharomyces cerevisiae, and sugarcane juice or molasses. The industrial production of ethanol in Brazil is characterized by a non-aseptic process, where the must (a mixture of juice, molasses, and water) doesn´t pass through any type of treatment that aimed to eliminate microbial contamination. Due to these characteristics of the fermentation process in Brazil, one of the factors that can influence fermentation yield is bacterial contamination, which tends to have detrimental effects on the process due to competition for nutrients. However, the interaction between yeasts and contaminating bacteria found in the process is not fully elucidated and may not be entirely harmful, with a complex and dynamic synergy related to the metabolites formed. In this context, the present study proposes to evaluate the impact of interactions between yeasts and bacteria on fermentation yield, cell growth, ethanol production, and by-products. For this purpose, mixed fermentations were conducted in semi-synthetic medium between the yeast Saccharomyces cerevisiae and four different contaminants commonly found in the sugarcane industry. Limosilactobacillus fermentum, Lactobacillus helveticus, Lactiplantibacillus plantarum, and Lactobacillus amylovorus were studied at four cell concentrations (105, 106, 107, and 108 cells per mL) in consortium with the yeast. Ethanol, sugars, acetic acid, lactic acid, and glycerol were quantified, in addition to the biomass formed. The research showed that Limosilactobacillus fermentum negatively affected yeast cell growth and fermentation efficiency, while Lactobacillus helveticus, even though not remaining until the end of fermentation, caused a reduction in efficiency, with high levels of lactic acid, exceeding those in the L. fermentum trials. L. plantarum did not demonstrate the positive synergies reported in the literature, while Lactobacillus amylovorus contributed to increased fermentation efficiency and cell growth. The results emphasize the importance of understanding microbial interactions to optimize ethanol production and demonstrate that there are different forms of synergy among microorganisms, influenced by the medium and cell concentration.

Professionals in rural schools with multi-grade classes, present throughout the country, face major challenges in their pedagogical practices, especially in literacy. This research aimed to analyze the challenges and potentials of literacy practices in multi-grade classes in rural schools of a municipality in the state of Mato Grosso, Brazil. The research question was: How do teachers of rural multi-grade classes articulate and organize their literacy practices? A case study was conducted with three professionals who worked in municipal public rural schools in the school years of 2022 and 2023. These professionals taught classes with 1st and 2nd grades in the same classroom. Data collection was carried out through semi-structured interviews, based on Minayo (1994, 2014), Penna (2020), Ludke and André (1986), and Bardin (1979). The investigation discussed the current legislation on literacy and addressed theories related to the teaching of reading and writing, with contributions from theorists such as Soares (2000, 2009, 2021a, 2021b, 2022), Mortatti (2011), and Bagno (2011, 2021). The discussion on rural education was based on Azevedo and Queiroz (2010), Caldart (2012), Arroyo (2011), and Fernandes (2002). The research results were organized into four categories: "Challenges in rural literacy", "Teaching strategies for diversity", "Literacy potentialized in rural multi-grade classes", and "Formative needs based on challenges shared by rural teachers". The research results indicate the need for specific training for working in rural areas. We observed a variety of adapted approaches to the needs of the classes, but with some gaps in relation to the practices recommended in the BNCC and Magda Soares' theoretical orientation for reading and writing skills in the early years of elementary school. Additionally, some limitations of literacy practices were noted due to the use of standardized materials (textbooks). There is also an urgent need for public policies aimed at Rural Education, promoting professional appreciation and pedagogical approaches sensitive to the needs of multi-grade classes.

Wheat Fusarium Head Blight (Gibberella zeae Schwein, Fusarium graminearum) is one of the most important diseases of this cereal worldwide, causing damage to grains in the form of atrophy, weight reduction, and discoloration. Besides yield loss, it also results in grain contamination by mycotoxins, posing a risk to human and animal health. Thus, managing the disease is a significant challenge for global wheat cultivation. No single strategy used in isolation provides satisfactory reduction of disease intensity and mycotoxin concentration under conditions favorable for pathogen development. This study aimed to evaluate the technical feasibility of integrating fungicide, genetic resistance, and silicon in managing Gibberella in irrigated and rainfed production systems. The experiments were conducted using a randomized complete block design with three replications and four treatments, namely: T1 – Fungicide + Potassium Silicate (F + SK) application; T2 – Fungicide (F) application; T3 – Potassium Silicate (SK) application; and T4 – Control (no F and SK application). In all experiments, the incidence, severity, and index of Gibberella, as well as mycotoxin concentration and productivity, were quantified. After performing variance analysis and Tukey's test (p<0.05). It was found that there was no significant difference between treatments for the agronomic variables. For the laboratory variables, T3 was the treatment that provided the greatest reduction in DON concentration, but it did not differ statistically from T1 and T2. It is concluded that the application of potassium silicate (PS) should be further explored for the reduction of DON. The application of PS may be an alternative in integrated management proposals for controlling wheat scab.

Since 2000, the perception of the satisfaction of electricity consumers has been collected and published by the Iasc – Aneel Consumer Satisfaction Index. Aneel, through resolutions, has promoted the customer-focused mentality among distributors and, in addition to encouraging awards, has made ISO9001 certification compulsory in processes directly related to customers. The objective of this study was to survey the policies, guidelines and strategic actions in the Brazilian electricity sector and how they contributed to the establishment of metrics to evaluate the performance of the sector, as well as to understand the impact of government action on the results of the indicators. For this, the data available from the Iasc – Aneel Consumer Satisfaction Index were used, which were submitted to statistical analysis to evaluate its performance. Given the statistical analysis, it was possible to assume as true the initial hypothesis that the implementation of ISO9001 contributed to improving the perception of the quality of services provided.

Recent studies have shown the negative environmental effects of spray paints due to microplastics (MPs) and their chemical composition. Photodegradation of these particles can increase the release of additives, including metals in the pigments. Neotropical bumblebees can be exposed to these contaminant particles, which have already been found in honey. Therefore, this study aimed to evaluate the effects of photodegradation on spray paints MPs exposed to different light intensities and exposure times, as well as assess the potential cytotoxicity of these pristine and photodegraded MPs on the columnar cells of the midgut, Malpighian tubules, and hepato-nephrocitic system cells of forager worker bees of Bombus atratus exposed to 50 mg.L-1 of MPs for 96 hours. Pristine microplastics were obtained through paint spraying, then characterized by shape and size. Portable X-ray fluorescence (XRF) and Fourier Transform Infrared Spectroscopy (FTIR) were used to determine elemental composition and polymer type. The MPs were then exposed to different intensities of UV-C radiation and exposure times. The release of potentially toxic elements (PTEs) by the MPs was quantified using an atomic emission spectrometer with microwave plasma. To assess the toxicity of the MPs, we conducted histological and histochemical analyses of the bee tissues. The XRF analysis revealed several elements in both paints, including five PTEs: Manganese, Chromium, Iron, Copper, and Zinc. The particles exposed to the highest UV-C intensity showed significant changes, such as superficial modification, blooming of additives, and surface detachment resulting in voids, altering their area and roundness values in relation to the pristine. Additionally, they exhibited an increase in the release of PTEs, especially Iron, Manganese, and Copper, which exceeded the safe limits set by the National Environment Council of Brazil (CONAMA). The increased release of PTEs is associated with the significant changes observed in the organs of bees exposed to the photodegraded MPs, which showed cellular vacuolization, nuclear condensation, and pyknosis. The release of PTEs from the photodegraded particles contributes to the disruption of the body homeostasis of the studied bees, potentially leading to reduced fitness and alterations in feeding and survival of the species. These findings underscore the importance of understanding the toxicity of environmentally realistic MPs, as plastic composition and weathering conditions can influence particle toxicity.

This dissertation presents an analysis of W.E.B. Du Bois’s social action theory, which was developed from the end of the 19th century. The study is methodologically close to Gilroy (1993) and Appiah (2014), interpreting Du Bois as part of a “line of descent” from black and African counterculture in modernity. From this, the argument is that Du Bois’s social action theory is different from the classical sociological tradition. Part of the analytical effort of this study, therefore, is the exercise of contrast between sociological theories of modernity and what Gikandi (2005) and Gooding-Williams (2009) classified as “Duboisian modernism”. It appears that theories of modernity explain human actions considering the process of rationalization of the world, interest, econometric motivation, and/or search for integration and social mobility. Du Bois’s social action theory, instead, is based on the principle of “chance” - historical processes that were not predicted, expected, or desired by the actors, such as colonization and the division of the world into racial groups. The study empirically uses a selection of texts written by Du Bois between 1930 and 1947, on Black Cooperativism and Pan-Africanism, which reinforce this interpretation of his social action theory and reconstruct the assumptions of Cultural, Post-Colonial, and African Diaspora Studies.

Theoretically based on Differential Geometry, this writing highlights the relevance of this complex mathematical area and its potential to enrich the Mathematics teaching and learning, especially at more advanced levels. By studying Differential Geometry, it was possible to establish a connection between this content and elementary education, especially in the artography study, whose skill is included in the National Common Curricular Base (BNCC). Connection between Differential Geometry and Cartography aims to provide broader and more contextualized theoretical support to the teacher. Didactic Transposition is explored as an important strategy for this integration. Through it, it is possible to translate the abstract concepts of Differential Geometry into a language accessible to students, making the educational process more meaningful. The developed class plan offers ideas to improve pedagogical practice, highlighting the expressive role of the teacher when preparing their classes, not only as a transmitter of knowledge, but as a learning process facilitator, promoting interdisciplinary connections and stimulating critical thinking and creativity of students.

Chikungunya is a viral disease primarily transmitted by Aedes aegypti mosquitoes. Since its introduction in Brazil in 2014, the disease has spread rapidly, becoming a significant public health problem. This study aims to explore the transmission dynamics of Chikungunya in Brazil through mathematical modeling. We use compartmental models to describe and predict the disease’s spread, formulating ordinary differential equations solved by the numerical Euler method. The methodology also included estimating the model parameters, fitting them to actual observational data. The results demonstrate that the developed model can replicate aspects of the transmission dynamics of Chikungunya, identifying critical factors that influence its spread. We conclude that mathematical modeling is an essential tool for formulating public policies and more effective control strategies, significantly contributing to the epidemiological understanding of Chikungunya in Brazil.

The thesis aims to analyze the recommendations for adult literacy in the first ten years of development of the Major Project of Education for Latin America and the Caribbean approved by the United Nations Educational, Scientific and Cultural Organization for implementation in the period from 1980 to 2000. The thesis targets three literacy experiences in Latin America and the Caribbean: Argentina, Nicaragua, and Cuba. It takes as its theoretical-methodological framework concepts of history based on Le Goff (2010) and Bloch (1963) and dialogues with other authors to produce this research. It adopts the methodology of historical research and, thus, examines twenty bulletins by United Nations Educational, Scientific and Cultural Organization during the first ten years of the project, as well as texts produced by this organization during the period. The thesis concludes that thinking of literacy as an ally of economic and social development, as advocated in the PPE (1980-2000), does not contribute to the construction of a more just world for all, since such a purpose only helps to maintain, in the past and present, a world economic order founded on the exploitation of the poor (countries and people) and inequalities.

This capstone project presents the development of a framework for selecting mobile sensors for the digital phenotyping of university students with possible depressive profiles. Inspired by a seminal study by Torous that analyzes digital phenotyping in varied contexts, this work performs a critical reinterpretation of this literature to adapt and apply concepts to the specific context of depression in academic settings. The proposed framework was developed based on a review of existing work that uses behavioral data captured by sensors on smartphones and other mobile devices, such as GPS and accelerometers, to identify patterns that may be related to depressive symptoms. The methodology involved collaborative discussions with experts in computing and health, seeking to align the technical capabilities of the sensors with the diagnostic and therapeutic needs of potentially depressed students. As a result, possible relationships are presented between the data collected by the sensors and symptoms of depression. This study aims to provide a basis for future practical implementations of computer systems mental health support, using accessible and non-intrusive technologies in educational contexts.

Chronic respiratory and cardiovascular diseases impose a significant burden on healthcare systems and economies, sharing risk factors and control measures. Both conditions involve muscular strength impairment, yet comparative evidence on the magnitude of this impairment is scarce. Therefore, understanding the impact of muscle weakness on exacerbations of chronic obstructive pulmonary disease (ECOPD) and decompensated heart failure (DHF) is essential for clinical practice, potentially optimizing care and improving functional outcomes for these patients. Objectives: To analyze whether there is a difference in peripheral muscle strength impairment and exercise capacity in hospitalized patients with exacerbations of COPD and decompensated heart failure. Additionally, we aim to assess whether muscle strength contributes to exercise intolerance in these populations. Methods: Observational, cross-sectional study including patients diagnosed with exacerbated COPD and decompensated HF, assessed between 24 and 72 hours after hospital admission. Evaluation included grip strength, quadriceps muscle strength, and exercise capacity using the 6-minute walk test (6MWT). Results: Each group consisted of 15 patients. Regarding mean grip strength, quadriceps strength, and exercise capacity, both groups showed a mean below 70% of predicted values. When analyzing the relationship between grip strength, quadriceps strength, and 6MWT distance, a high percentage of patients in both groups exhibited muscle weakness and low exercise capacity (67% in the ECOPD group and 87% in the DHF group). We observed greater variability in systolic blood pressure post-exercise, higher peak heart rate, increased dyspnea, and greater fatigue in lower limbs during exercise in the ECOPD group. There was no significant correlation between muscle strength and 6MWT distance in the ECOPD group, whereas a moderate and significant correlation was found between grip strength and 6MWT distance (R= 0.52, p = 0.04), and a strong and significant correlation between quadriceps strength and 6MWT distance (r = 0.79, p < 0.01) in the DHF group. Conclusion: Muscle strength impairment and exercise capacity are similar between COPD and HF populations during acute exacerbations. While muscle weakness may be an important factor associated with exercise capacity in DHF patients, exercise limitation in ECOPD patients appears to be influenced by more intense symptoms.

The high prevalence of hand injuries and diseases has a significant impact on people's occupational performance and occupational therapy intervention plays a crucial role in promoting rehabilitation and improving their quality of life. Introduction: The manufacture and prescription of orthoses in an individualized and personalized way seeks to maximize the functionality, autonomy and social participation of these individuals, with a view to resuming daily activities and reintegrating them into meaningful occupations. Objectives: The research aims to identify the demands and establish a relationship between the types of orthoses made and the diagnoses presented by the participants assisted during the occupational therapy extension project called “ Manufacture of Orthoses for Upper Limbs in Adults with Physical Dysfunctions” carried out in a Health Unit linked to a Federal University in the interior of São Paulo. Methodology: This is a quantitative and descriptive study, which analyzes the relationships between variables using standardized data collection techniques, for which we will use the records of the extension project's census notebook, from June 2017 to June 2023. The main instrument will be data collection, which in turn will include information such as age, diagnosis and type of orthosis made. Results: The average age of the patients treated was 54.8 years, with the lowest age being 15 and the highest 85. With regard to the total number of orthoses (n=225) devices made according to the data collected from the Extension Project's Orthosis Census, the most commonly made were cock-up orthoses, type eight orthoses and dynamic orthoses. The most common diagnoses were carpal tunnel syndrome, various injuries and trigger fingers. Conclusions: The importance of ongoing research into data on the manufacture of upper limb orthoses in the practice of occupational therapists was noted. This study has limitations, as the orthosis census records had some inconsistent information, and only one health unit's extension project was analyzed. Future studies could include more projects and/or health units in order to gain a better understanding of the most common orthoses and diagnoses.

Brazil and China are considered important references for industrialization in developing economies, however, they have followed different industrial policy strategies and macroeconomic contexts in recent decades, which has led these economies to follow different paths. The objective of this paper is to develop and analyze comparative indicators of technological upgrading for Brazil and China during the period from 2001 to 2020, offering a more accurate and qualitative perspective for understanding these two national configurations. To achieve this, a comparative analysis of technological upgrading indicators between Brazil and China was conducted, based on the theoretical assumptions and indicators suggested by Radosevic and Yoruk (2015, 2017): intensity of technological upgrading, scope of technological upgrading, and interaction with global technology. A calculation based on the Euclidean distance (ED) was used to arrive at the value of technological upgrading and its component indices. As a result it was observed that both economies started the period with similar indicators, but that China showed superior performance in most components throughout the period.

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by persistent deficits in social communication, social interaction, and the presentation of restricted and repetitive patterns of behaviors, interests, and activities. The high demands related to caring for an autistic child can impact different areas of family life, such as health, work, and leisure. Women are the main caregivers of their children with autism, and the need to provide continuous caregiver burden, with specific attention, can lead the caregiver to experience situations of care. In this sense, the literature points out that social support is a fundamental aspect in coping with caregiver burden, mental health, and the quality of life of caregivers. The present study aimed to: (1) investigate the levels of caregiver burden and the perception of social support of mothers and fathers of children with ASD, verifying the relationship between these variables and (2) compare whether there are gender differences in terms of these variables. A total of 103 caregivers participated in the study, 74 mothers and 29 fathers of autistic children over 18 years of age, regardless of the level of support required by the child. The instruments used were: Participant Characterization Questionnaire, Pediatric Disability Assessment Inventory (PEDI), Zarit Caregiver Burden Inventory (ISZ), and the Perceived Social Support Scale – Adults (EPSUS – A). The comparison results revealed that mothers are more burdened than fathers, and that both perceive low social support in a similar way. When analyzing the relationships, negative, highly significant, and moderately strong correlations were identified between caregiver burden and all assessed social support factors. In this sense, the study results showed differences in caregiver burden and similarities in the perception of social support, considering the caregivers' gender. Furthermore, it was concluded that social support is an important variable in minimizing caregiver burden for all participants and that it is also necessary to consider other factors in the family context. New studies are needed to expand the investigation into differences between fathers and mothers of people with autism. It is hoped that this research can support new discussions, effective public policies, and interventions aimed at the families of autistic people, as well as the community in which they are inserted, that promote awareness, acceptance, increased social support, and minimize the impacts of overload on the caregiver's mental health, well-being, and quality of life of these families.

Introduction: Hope is a dimension that makes up human life, fundamental in the process of facing complex situations. The COVID-19 pandemic context can interfere with the hope process of people using specialized mental health services. It is believed that hope was even more compromised in the perception of users of specialized mental health services, due to factors of social isolation, changes in daily routine, difficulty in accessing the care offered by mental health services, changes in the scope of work, doubts and uncertainties regarding the COVID-19 disease. Objective: To analyze the meanings of hope in the speeches of users of specialized mental health services in a city in the interior of Minas Gerais in the context of the COVID-19 pandemic. Materials and Methods: Qualitative study based on the theoretical and methodological framework of French-based Discourse Analysis (DA) and the theoretical construct of Dufault and Martocchio's Model of Hope. The research involved four specialized mental health services: Psychosocial Care Center for Alcohol and Drugs (CAPS ad), Psychosocial Care Center II, Multiprofessional Mental Health Center and Post-covid Mental Health Care Center belonging to a city in the interior of Minas Gerais. Semi-structured interviews were conducted with 14 users of specialized Mental Health services from August 2022 to May 2023. Discourse analysis devices were used to analyze the data. To analyze the data, the devices Interdiscourse, Metaphor and Paraphrase of Discourse Analysis were used. Results and Discussion: 14 interviews were carried out with users of specialized mental health services, 5 users of the Multiprofessional Mental Health Center, 4 users of CAPS II, 3 users of CAPS Ad and 2 users of the Post-COVID Mental Health Care Center. Of these 14 subjects, 10 were female and 4 were male. The discourse analysis process enabled the elaboration of two discursive blocks: 1) The meanings of Hope constructed in the COVID-19 Pandemic and 2) Experiences during the COVID-19 pandemic – What inhibits or promotes hope? The discursive block entitled “The meanings of Hope constructed in the COVID-19 Pandemic” addresses the meanings constructed about hope that are permeated by the effects arising from discursive memories. The discursive excerpts enunciate signs of religious discourse; solidarity speech; disease model. and overcoming speech. The discursive block entitled “Experiences during the COVID-19 pandemic – What inhibits or promotes hope?” explored life circumstances and experiences lived by the subjects that affected the production of meanings about hope in the pandemic context, which highlight the broad and strict production conditions in which the speeches were enunciated. The COVID-19 pandemic period was marked by experiences of grief, indifference, intensification of social injustices, fear and finding support within the family. Final Considerations: The COVID-19 pandemic influenced the construction of meanings about hope among users of specialized mental health services and generated consequences for people's mental health. It is believed to be important to enable health professionals, especially nurses, who work in CAPS and CAPS ad to understand the constructed meanings of hope and recognize it as a therapeutic resource that constitutes care. The importance of recognizing the promotion of hope as an intervention in clinical and care practice is highlighted.

Sustainable Supply Chain Management (SSCM) aims to minimize environmental impact and maximize profit and social well-being through sustainable practices. Given its complexity and the need to measure results, SSCM requires the support of a contemporary and multidimensional performance measurement system (PMS), aligned with strategic objectives common to the links in the supply chain. In parallel, the Fourth Industrial Revolution offers a range of digital technologies that promise to assist in the lifecycle of PMSs, making them more collaborative, agile, and flexible. Thus, the objective of this study is to propose a PMS model assisted by I4.0 technologies for SSCM. In this regard, PMSs are understood according to their resources, roles, and processes. SSCM is addressed considering the three dimensions of sustainability (environmental, economic, and social) and its various practices. Meanwhile, I4.0 technologies are investigated regarding their applicability in supporting PMS. To achieve the proposed objective, the research method used combines bibliographic methods (scientific mapping, systematic literature review, and content analysis), survey (conducted with experts in the areas), and the multi-criteria decision-making methods (MCDM) Fuzzy-VIKOR and Fuzzy-PROMETHEE. The thesis is structured as a compendium of articles, which aim to disseminate the bibliographic and empirical results of the methods used. The analyses and discussions developed in this thesis clarify how I4.0 technologies can be used in PMSs to achieve continuous improvement in SSCM practices. The developed model is directed at managers who seek a tool to achieve superior performance in SSCM, and who are willing to adapt to a new context of digitalization. Moreover, the work brings advances to the field and a research agenda for future references.

The present study aimed to investigate the implementation of risk management in federal public universities. It is a research study that, based on the theoretical framework, addresses the evolution of public governance and risk management, particularly in the context of federal public universities. It is understood that public governance involves evaluating, directing, and monitoring management to deliver a good or service of interest to society. For this purpose, risk management is shown to be a fundamental governance tool, integrating into decision-making so that senior management can identify and manage uncertainties and risks in advance to achieve institutional objectives. The central issue of the research was to understand how universities are dealing with the process of implementing risk management. To investigate this issue, a study of polar cases was conducted, focusing on identifying the actions taken and the difficulties encountered. The selection of institutions initially considered the evaluation of federal public universities regarding their organizational risk management capacity, according to the Integrated Profile of Organizational Governance and Public Management prepared by the Federal Court of Accounts. Subsequently, based on the application of specific criteria, the chosen universities were the Federal University of Lavras, the Federal University of Vales do Jequitinhonha and Mucuri, and the Federal University of Rio de Janeiro. Data collection was carried out through semi-structured interviews with participants holding management positions in the selected universities. The results identified difficulties that have prevented the universities from effectively implementing risk management. This may explain why in some universities, risk management is carried out merely as a formality. The study also identified best practices and suggestions that, if adopted, can assist in the effective implementation of risk management and the overcoming of identified obstacles.

The maintenance of Brazilian protected areas (UCs) relies on the management plan, which is an essential tool for defining the responsibilities and objectives of the UC, based on its biotic and abiotic characteristics. Birds are one of the best-known biological groups and their diversity reflects the variety of specializations, niche occupations, and ecological functions within ecosystems. In this study, a list of birds was compiled for the Juquery State Park, Franco da Rocha (JSP), SP, Brazil, which still lacks a management plan. The methodology was divided into a preliminary survey, carried out through citizen science websites and previous scientific publications. Subsequently, field efforts were undertaken to identify and validate the bird species currently present in JSP. These efforts resulted in 315 species which, after screening, culminated in the official list containing 264 species divided into 58 families and 23 orders. Passerines exhibited the greatest diversity, with a predominance of the families Thraupidae (34) and Tyrannidae (32), followed by Trochilidae (13) from the order Apodiformes. Twenty species are endemic to the Atlantic Forest biome, two are endemic to the Cerrado and one is typical of the Pampas. Based on the diversity of species detected in the field, the presence of threatened species, and the richness of migratory species, the JSP is defined as a fully-protected area according to the Brazilian law (“Unidade de Conservação de Proteção Integral”), and has proven to be an important area for the conservation of bird biodiversity in the metropolitan region of São Paulo. The avifauna composition is more than 50% similar to that of the the Cantareira State Park, which is a part of the mosaic of protected areas in São Paulo metropolitan area. Therefore, JSP is confirmed as a significant site for the conservation of bird biodiversity in the metropolitan region of São Paulo.

The present work focuses on the synthesis and characterization of mesoporous materials (MCM-41, MCM-41-NH2) and a mixed polymeric membrane (PEI ) for application in the adsorption of Cr3+ ions from aqueous solutions. The mesoporous materials were synthesized through a hydrothermal route, with MCM-41 being functionalized (MCM-41-NH2) with amino groups using the post-grafting method. Analysis of adsorption/desorption isotherms using BET revealed typical characteristics of mesoporous materials for both MCM-41 and MCM-41-NH2. The average BET pore diameter decreased from 13.07 nm to 4.06 nm upon functionalization. Using the CP-MAS methodology in NMR, three peaks were detected in the 13C spectra (C3 at δ 43 ppm, C2 at δ 23 ppm, and C1 at δ 10 ppm), indicating the presence of the functional group in MCM-41-NH2. The 29Si spectra showed changes in the binding sites, with peaks corresponding to Q2 [SiO2(OH)2] at δ 110 ppm, Q3 [SiO3-OH] at δ 120 ppm, and Q4 [SiO4] at δ 130 ppm in MCM-41. In the spectrum of MCM-41-NH2, the disappearance of the Q2 site and the appearance of peaks corresponding to T2 sites [C-Si(OSi)2OH] at δ 87 ppm and T3 sites [C-Si(OSi)3] at δ 82 ppm were observed, along with the Q3 and Q4 sites at δ 120 ppm and δ 130 ppm, respectively. This confirmed the presence of covalently linked aminopropyl groups. The presence of free silanol groups (Q3 sites) in the MCM-41-NH2 spectrum indicates incomplete functionalization of the mesoporous material with amino groups. Next, an NMR-DT methodology was proposed to determine the adsorption kinetic parameters of Cr3+ ions. A determination coefficient (r²) of 0.9965 was achieved, with a limit of detection (LD) of 1.02 mg·L⁻¹ and a limit of quantification (LQ) of 3.08 mg·L⁻¹. The Langmuir and Freundlich models were used to fit the Cr3+ adsorption data, with maximum adsorption capacity (Qmax) values of 50.98 mg·g⁻¹ and a Freundlich coefficient (Kf) of 9.65 mg·g⁻¹. In comparison, chemically modified sugarcane bagasse showed Qmax = 22.08 mg·g⁻¹ (Langmuir) and Kf = 3.65 mg·g⁻¹ (Freundlich), demonstrating that, under the experimental conditions, MCM-41-NH2 exhibits superior adsorption capacity. Furthermore, the adsorption rate law was determined to be V = k·[MCM-41-NH2]^0.3·[Cr3+]^0.7, with an activation energy (EA) of 588.0 J·mol⁻¹. The mixed polymeric membrane, consisting of PEI , was synthesized via the phase inversion process in proportions of 2.5%, 5.0%, and 10%, and was characterized. The study of the adsorption kinetics of Cr3+ ions did not yield satisfactory results. Without agitation, the membrane did not remove ions from the solution, and under agitation, the PEI membrane (10%) only showed approximately 15% removal. The initial concentration was 291.1 ± 0.7 mg·L⁻¹, and after 12 hours of stirring, the concentration in the solution was 246.3 ± 0.5 mg·L⁻¹. These results highlight the potential of MCM-41-NH2 as a highly efficient material for the removal of Cr3+ ions from aqueous solutions, with NMR-DT emerging as a promising alternative methodology for determining adsorption kinetic parameters.
