Increased Shelf-Life of Hawaiian Papaya by Coatings Based on Chitosan/Cassava Starch Blends Added with TiO2
This study aimed to evaluate the effect of chitosan/cassava starch/TiO2 coatings on the respiratory activity, physicochemical properties, and commercial/postharvest quality attributes (appearance, odour, colour, fungal incidence, shine, and film adhesiveness) of Hawaiian papaya. Three treatments were evaluated: uncoated papaya (control), papaya coated with chitosan/cassava starch (1:1) (CH/ST), and papaya coated with chitosan/cassava starch (1:1) containing 1% TiO2 (CH/ST/T). The fruits were stored under fluorescent light at 22 ± 1 °C and 80% ± 1% RH, for 18 days. The biopolymeric coatings acted as a physical barrier, reducing the respiratory rate and mass loss, delaying senescence-associated metabolic changes and slowing chlorophyll degradation and carotenoid accumulation. The coatings maintain pulp firmness, soluble solids, titratable acidity, and internal quality, resulting in fruits with superior sensory attributes and greater commercial appeal. The coatings also showed good adhesion to the fruit peel, reduced fungal incidence, and maintained desirable odour, colour, shine, and overall acceptance. The coating containing TiO2 (CH/ST/T) was the most effective in extending the shelf life of papaya by six and nine days, compared to fruits treated with TiO2-free coating (CH/ST) and the uncoated control, respectively.

PROJETO INTEGRADO E VERIFICAÇÃO NUMÉRICA DE SISTEMA DE FREIOS A DISCO PARA VEÍCULO OFF-ROAD LEVE UTILIZANDO ANÁLISE POR ELEMENTOS FINITOS
Sistemas de freios a disco aplicados a veículos off-road estão sujeitos a severas solicitações termomecânicas, decorrentes de carregamentos dinâmicos variáveis, superfícies de baixa aderência e eventos de frenagem de curta duração e elevada energia. Embora a literatura aborde aspectos isolados, como análise estrutural, seleção de materiais e dimensionamento hidráulico, ainda são escassas abordagens que integrem, de forma coerente e verificável, a dinâmica veicular, o dimensionamento hidromecânico e a verificação computacional, especialmente em plataformas leves do tipo Baja SAE. Este trabalho propõe e valida uma metodologia de projeto integrada, estruturada em cinco fases, para o desenvolvimento de um sistema de freios a disco para um protótipo Baja SAE. A abordagem combina modelagem analítica da dinâmica longitudinal, baseada em modelo de dois graus de liberdade, modelagem paramétrica em CAD e simulações por elementos finitos (FEA), incluindo análises estruturais e térmica transiente, com validação por modelo de capacitância concentrada. Os resultados indicam que a frenagem a 0,60 g eleva a força normal no eixo dianteiro em 78,6%, concentrando 59,6% da força de frenagem, justificando a adoção de discos assimétricos. O sistema apresentou eficiência superior a 90% para µ = 0,60, com tendência ao bloqueio traseiro para µ > 0,70. As análises estruturais confirmaram regime elástico, com fatores de segurança de 2,46 para o pedal (SAE 1020) e superiores a 2,52 para os discos (SAE 1045). A simulação térmica indicou temperatura máxima de 237 °C na interface pastilha–disco ao final de 3 s, abaixo da faixa crítica de degradação (~300–400 °C), com boa concordância entre os modelos numérico e analítico. A metodologia proposta demonstra que a integração entre dinâmica veicular, dimensionamento analítico e simulação computacional constitui abordagem eficaz e reprodutível para o projeto de sistemas de frenagem em veículos off-road de pequeno porte

Otimização da cementação sólida em engrenagens de aço AISI 8620: modelagem estatística e influência das variáveis de processo na dureza superficial e absorção de carbono
A cementação sólida permanece amplamente empregada na fabricação de engrenagens e eixos em aço AISI 8620, sobretudo em produções de menor escala. No entanto, a literatura ainda carece de modelos capazes de descrever, de forma integrada, a influência simultânea dos parâmetros de processo e das características geométricas sobre as propriedades superficiais, limitando a previsibilidade do tratamento termoquímico. Nesse contexto, este trabalho desenvolve e valida modelos preditivos para a dureza (HRC) e a concentração de carbono (%C), avaliando os efeitos da temperatura (850–950 °C), do tempo (4–8 h) e do diâmetro (20–60 mm) por meio de planejamento fatorial completo 2³ com pontos centrais. Para isso, Corpos de prova cilíndricos foram cementados em mistura de carvão vegetal e BaCO₃ (85/15% m/m), seguidos de têmpera em óleo mineral a 60 °C e revenimento a 180 °C por 1 h. A caracterização foi realizada por dureza Rockwell C, conforme ASTM E18-22, e espectrometria, conforme ASTM E1019-18, com análise estatística baseada em ANOVA, regressão múltipla e metodologia de superfície de resposta (α = 0,05). Os resultados indicaram que, para a dureza, temperatura, tempo e sua interação foram significativos (R² = 85,9%; p = 0,002), com capacidade preditiva moderada associada à heteroscedasticidade (p = 0,038). Para o carbono, o modelo foi significativo (F = 29,33; p < 0,001; R² = 95,86%), com a interação A×C não significativa (p = 0,081). A condição ótima (950 °C, 8 h, 20 mm) resultou em 62,4 HRC e 1,18%C, atendendo às normas ISO 6336 e AGMA 2001.

Structure–Property Relationship of Cassava Starch Films Modified with an Anionic Surfactant and Their Performance as a Coating on Tahiti Lime (Citrus latifolia)
Edible coatings based on cassava starch (CS) can reduce postharvest losses, although their high hydrophilicity limits barrier performance. This study investigated CS films plasticized with glycerol and modified with saponified sunflower oil (SSO) as an anionic surfactant. Film-forming formulations with different SSO contents were prepared, characterized, and subsequently applied as coatings on Tahiti lime (Citrus latifolia) to evaluate their effectiveness during storage. Increasing SSO content enhanced film transparency without promoting undesirable yellowing. Its effect on water resistance, however, was non-linear: the formulation containing 0.01 g SSO reduced water vapor permeability by 41.09% relative to the surfactant-free film, whereas the highest SSO level maintained the hydrophilic character of the matrix but increased flexibility, with elongation at break rising by 98.29% and elastic modulus decreasing by 52.45%. Structural and microstructural analyses indicated that SSO modified matrix organization, reducing crystallinity and altering surface homogeneity. Principal component analysis of film properties reinforced this behavior, isolating the 0.01 g SSO formulation as the only one combining minimum water vapor permeability and maximum contact angle. When applied to Tahiti lime stored at 25 ± 2 °C and 60 ± 5% RH, this coating showed the most favorable overall postharvest performance, reducing weight loss and delaying visual and physicochemical deterioration. Multivariate analysis of postharvest data confirmed a more favorable intermediate-storage trajectory for this treatment, whereas the highest SSO level showed a distinct late-storage acid/ascorbate profile consistent with greater fungal incidence.

AI TRENDS IN EDUCATION: A BIBLIOMETRIC ANALYSIS OF EMERGING CONTEXTS
Artificial intelligence (AI) is emerging as a transformative force in education, driving personalized teaching and mitigating educational inequalities. This study aims to analyze, through a bibliometric approach, the main trends in the application of AI in education, with an emphasis on scientific production associated with developing countries and contexts with limited infrastructure, and to identify advances, challenges, and opportunities. The methodology used was bibliographic research, characterized by systematic analysis of the literature. Data were collected from the Scopus and Web of Science (WoS) databases, covering the period from 2014 to 2024. After screening and applying inclusion and exclusion criteria, 634 documents were selected. Reference management was performed using Zotero, and data organization and cleaning was conducted on the Rayyan platform. Bibliometric analysis was conducted using the Bibliometrix package in RStudio software, and VOSviewer was employed for the scientific mapping and analysis of co-authorship and co-occurrence networks. The results revealed an increase in scientific production of AI in education from 2019 onwards, intensified by the COVID-19 pandemic. China, the United States, and India stood out as the countries with the most significant scientific production and academic impact in the field. Despite these advances, the study highlighted several challenges, including infrastructural barriers, algorithmic bias, a lack of teacher training, and ethical risks associated with the collection and use of sensitive data. It is concluded that the ethical, equitable, and contextualized use of AI in education requires public policies committed to digital inclusion, ongoing teacher training, and investments in accessible technologies that are sensitive to local realities.

The Shelf Life of Yellow Passion Fruit with an Edible Biocomposite Coating Based on Chitosan, Graphene Oxide Nanoparticles, and Beeswax
Yellow or sour passion fruit is a climacteric fruit with a high rate of respiration and ethylene production, and postharvest technology is needed to extend its shelf life. This study investigated the properties of a biocomposite film with chitosan (CH) incorporated with beeswax (BW) and graphene oxide (GO) nanoparticles for use as an edible coating to extend the shelf life of yellow passion fruit at 22 °C and 70% RH for eight days. CH films associated with BW showed lower water vapor permeability (WVP) than films with CH alone. However, adding GO to the CH + BW biopolymer matrix improved the WVP, decreased the solubility (12.8%), and increased the opacity of the film by 9% compared to those of the CH film. Fruits coated with CH + BW or CH + BW + GO exhibited a reduction in respiration rate, a slower ripening process by approximately 3 days, and a significant decrease in weight loss. This also resulted in a higher soluble solids content and increased antioxidative capacity of the pulp. The incorporation of GO into the CH + BW matrix resulted in a more pronounced delay of fruit ripening, as evidenced by the lower depigmentation of the peel at eight days, with a lightness approximately 10.7% lower at 54.92, a chroma value 16.5% lower at 49.33, a hue angle 7.2% higher at 92.56, a soluble solid (SS) content 16.7% higher at 11.32°Brix, and an acidity 31.9% higher at 4.18% compared to the control. Furthermore, the biopolymer packaging led to a higher consumer acceptance score for the fruit.

A gestão de resíduos sólidos (GRS) no Brasil a partir do ano de promulgação da Política Nacional de Resíduos Sólidos (PNRS): uma análise bibliométrica
A implantação de estratégias sustentáveis na gestão dos resíduos sólidos (GRS) é um desafio constante para os gestores públicos do Brasil. A Política Nacional de Resíduos Sólidos (PNRS), foi aprovada em 02 de agosto de 2010 e é considerada o principal instrumento norteador para GRS em todo território nacional. Os dados elaborados por meio dos estudos bibliométricos mensuram a contribuição do conhecimento científico derivado das publicações em determinadas áreas. Os indicadores de produção são úteis para o planejamento e a execução de políticas públicas, e para o conhecimento da comunidade científica. Diante disso, o objetivo deste trabalho é realizar um estudo bibliométrico sobre a produção científica brasileira referente GRS a partir da análise de publicações em periódicos indexados na base de dados do Web of Science (WoS). Os dados foram coletados utilizando operadores booleanos ("solid waste" or "solid waste management"). São analisadas 1.690 publicações distribuídas em 10 áreas de conhecimento, entre 2010 e 2021. Entre artigos analisados foi observado uma evolução expressiva da produção científica brasileira sobre essa temática nos últimos anos, com forte contribuição da Universidade de São Paulo (USP). A implementação da PNRS somada as pressões de órgãos internacionais, as reações do meio ambiente e suas consequências econômicas e na vida das populações urbanas, contribuíram significativamente para a evolução nas pesquisas sobre a GRS.
