Item type: Item , Entre jogar e se proteger: uma leitura gestáltica das experiências de violência de gênero em jogos eletrônicos(Universidade Federal de Goiás, 2026-06-26) Rosa, Sarah Dantas Dias; Gimbo, Leda Mendes Pinheiro; Gimbo, Leda Mendes Pinheiro; Andrade, Celana CardosoThis study aimed to understand, from a Gestalt therapy perspective, the experiences of genderbased violence in electronic games as reported by cisgender women enrolled in the Psychology program at the Universidade Federal de Goiás. The research is basic in nature, with a crosssectional design, exploratory-descriptive objectives, and a qualitative approach. Four cisgender women participated in the study, with whom individual semi-structured interviews were conducted. The interviews were recorded and transcribed, and the transcriptions were submitted to MAXQDA 26.0.0 software, used as an analytical support tool, resulting in 760 occurrences distributed across 16 codes organized into three analytical axes: Contact and Identity, Game Elements, and Violence. The theoretical framework drew on gender studies, the understanding of electronic games as gender technologies, and Gestalt therapy concepts, particularly Self Theory and the misery adjustment. The results indicate that gender-based violence manifests in games both through symbolic violence embedded in their content and through relational violence present in player interactions within online multiplayer games. Faced with these experiences, participants develop creative adjustments, such as muting their microphone, avoiding certain game styles, and restricting themselves to accompanied matches, understood as expressions of the misery adjustment, which arises from conditions external to the subject that constrain spontaneous action in the field. It is concluded that gender-based violence in electronic games is part of the patriarchal logic that regulates which bodies may occupy certain spaces, producing effects that compromise the players' self beyond the specific episodes of victimizationItem type: Item , “Kiki” e “Chihiro”: infância e amadurecimento nas obras de Hayao Miyazaki(Universidade Federal de Goiás, 2026-07-01) Castro, Nayra Caroline dos Santos; Freitas, Gabriel Rocha; Viana, Cynthia Maria Jorge; Viana, Cynthia Maria Jorge; Freitas, Gabriel Rocha; Santos, Soraya VieiraThe purpose of this study is to study the representation of childhood, highlighting the coming of age, the attainment of independence, and identity construction in the animated films Kiki’s Delivery Service (1989) and Spirited Away (2001), cinematic works directed by Hayao Miyazaki. To this end, a qualitative and bibliographic research was conducted alongside a filmic analysis guided by an analytical framework based on authors such as Oliveira (2016), Kramer (2007), Pessel (2009), Teixeira and Foncêca (2024), among others. This study is divided into five sections, with the First Section serving as the introduction. The Second Section addresses the director's biographical background and his auteur style. The Third Section presents a description of the films Kiki’s Delivery Service (1989) and Spirited Away (2001). The Fourth Section analyzes the journeys of the protagonists in the movies, emphasizing key elements of childhood, the role of labor in the construction of the identity of the analyzed protagonists, the act of saving the other as the peak of maturation, and the counterpoint of "Boh," a character who embodies an overprotected childhood. In the Fifth Section, titled Final Considerations, the findings of the research are presented, revealing that childhood and maturation in these films by Miyazaki are not isolated heroic triumphs, but rather a continuous process of confronting insecurities and assuming responsibilities with collective support, reaffirming the importance of conscious autonomy in the transition to adulthoodItem type: Item , A critical review of holistic 4E approaches for assessing sustainable aviation fuel pathways: implications for feedstock, technology, policy and scale-up(2026) Gonzales, Thiago da Silva; Lamas, Giulia Cruz; Silva, Simone Monteiro e; Ferreira, Ana Filipa; Silveira, Edgar AmaralThe aviation sector urgently requires decarbonization, positioning Sustainable Aviation Fuels (SAF) as the most viable near-term option for reducing fossil jet fuel dependence. However, SAF scale-up remains constrained by coupled technological, thermodynamic, economic, environmental, and policy related trade offs. Although many studies assess individual dimensions of SAF production, the literature still lacks a critical synthesis explicitly connecting Energy, Exergy, Economic, and Environmental (4E) evidence across certified pathways. This review examines 4E related approaches applied to SAF by linking energy and exergy analyses with techno economic assessment, life cycle assessment (LCA), and their exergoeconomic and exergoenvironmental extensions where available. The systematic review reveals a fragmented evidence base, with only a limited subset of studies quantitatively addressing all four dimensions. Hydroprocessed Esters and Fatty Acids remains the most mature and economically competitive route, but its scalability is limited by sustainable lipid feedstock availability, hydrogen sourcing, and land use constraints. Gas-to-Jet, Alcohol-to-Jet, and Sugar-to-Jet offer greater feedstock flexibility or biochemical innovation, but face higher capital intensity, upgrading complexity, hydrogen demand, or blend limit restrictions. Across pathways, thermodynamic irreversibilities in heat exchange, separation, syngas conditioning, fermentation, and upgrading stages propagate into cost formation and environmental burdens. LCA evidence shows that Greenhouse gases reductions depend strongly on feedstock origin, hydrogen source, allocation choices, and system boundaries. By organizing these interdependencies through a pathway level 4E indicator linking matrix, this review provides an evidence based foundation for more transparent comparative assessments, process optimization, investment analysis, and policy design for SAF deploymentItem type: Item , Techno-economic and CO2 net assessment of dimethyl carbonate production from biomass-derived methano(2025) Custodio, Renan Fagundes; Valarini Junior, Osvaldo; Vieira, Admilson Lopes; Souza, Thiago Leandro de; Bezerra, Felipi Luiz de Assunção; Rocha, Lucas BonfimThe increasing concern over greenhouse gas emissions, particularly CO2, has emphasized the urgency for practical solutions to mitigate the environmental impacts of climate change. This study assessed the technical, economic, and environmental feasibility of producing dimethyl carbonate (DMC) through an integrated route using methanol derived from biomass gasification in sugarcane-based industries. Unlike previous studies that analyzed isolated aspects of DMC production, this research was conducted through process modeling and simulation in Aspen Plus® V12.1, evaluating key performance indicators such as conversion rates, product purity, capital and operating expenses, and CO2 emissions. A DMC conversion rate of 78.06% and a purity level of 96.80% were achieved. However, the integration of methanol production increased both CAPEX and OPEX, leading to a net present value (NPV) of R$ 36.7 million over 10 years, lower than alternative routes using commercially available methanol. Additionally, the process resulted in a net CO2 emission of 3.41 kg CO2 per kg of DMC, exceeding conventional methods. These findings suggest that under the evaluated conditions, process integration did not offer economic advantages, despite many environmental advantages over commercially available methanol.Item type: Item , Core–shell structured PtCu/C applied in a high-temperature direct ethanol electroreformer to produce green H2 at reduced energy demand with high CO2 selectivity: performance and techno-economic analyses(2026) Paula, Dryade Ferreira de; Crisafulli, Rudy; González Cobos, Jesús; Caravaca, Angel; Linares León, José JoaquínThree different electrocatalysts have been prepared, characterized, and applied to a high-temperature direct ethanol polymer electrolyte membrane electroreformer (DEPEME) based on the removal of surface Cu from the initial PtxCu/C (x = 3, 1, and 1/3) raw materials. The resulting structure consisted of a Pt-enriched shell on a PtCu alloy core deposited on C [alloyed PtxCu@PtyCu/C (y c x)], achieved after the acid treatment of the prepared catalysts, in a core–shell (CS) configuration. This structure is confirmed by X-ray diffraction, which evidences the formation of a PtCu alloy, whereas X-ray photoelectronspectroscopy reveals an enriched Pt shell. Finally, transmission electron microscopy images revealed the dispersed deposition of metal nanoparticles at the nanoscale range. Regarding the electrochemical performance, the CS materials displayed enhanced CO tolerance and ethanol electro-oxidation (EEO) performance, characterized by increased current density and a lower onset potential compared to Pt/C. These results were corroborated at the high-temperature DEPEME condition of 150 1C. Moreover, the monitoring of the EEO products revealed that the CS PtCu materials notably enhanced the selectivity for CO2, resulting in a desirable combination of high hydrogen production rate (0.205 kg of H2 m2 h1) and CO2 selectivity (close to 50%) at a reduced energy consumption (25.46 kWh kg H21). Finally, a techno-economic analysis presents the potential of using ethanol produced in a sugarcane plant from bagasse (second-generation) and estimates the cost of H2 produced compared to that of a PEM water electrolyzer.
