Combinando peças: o efeito semântico de 'junto(s)' e 'sozinho(s)' na combinação com predicados distributivos e coletivos
(Universidade Federal de São Carlos, 2026-09-18) Araújo, Ana Carolina de Sousa; Basso, Renato Miguel; http://lattes.cnpq.br/6984826176670527; http://lattes.cnpq.br/1632059549342508; https://orcid.org/0009-0003-1380-4622; Ferreira, Thayse Letícia; Mendes, Luciana Sanchez; http://lattes.cnpq.br/2072872902614187; http://lattes.cnpq.br/7322728409384122
This study aims to analyze the functioning of sentences combining distributive and collective predicates with the items ‘junto(s)’ (together) and ‘sozinho(s)’ (alone) in Brazilian Portuguese (BP). Initially, one might think that such combinations would generate infelicitous sentences in the language, since the expressions ‘junto(s)’ and ‘sozinho(s)’ could be understood as anti-distributivity and anti-collectivity modifiers, respectively, which would result in redundant or contradictory readings when combined with distributive and collective predicates. Seeking to understand whether this initial intuition would be confirmed, we first proposed an investigation into the semantic characteristics of distributive and collective predicates – as well as those that are ambiguous between these two readings – in BP, based on studies by Araújo and Lardapide (2025), Champollion (2019; 2020), Müller, Negrão, and Gomes (2007), Ritchie (2017), Winter (2001), among others. Furthermore, we present initial inventories with examples of the different types of predicates. We also analyze the semantics of the items ‘junto(s)’ and ‘sozinho(s)’ in BP, drawing from the works of Araújo, Palmieri, and Basso (2026), Basso and Araújo (2024), and Basso and Rodrigues (2024). Having described the behavior of the predicates and modifiers in question, we proceeded to analyze the sentences generated by combining collective and distributive predicates with the items ‘junto(s)’ and ‘sozinho(s)’. To this end, we selected four distributive, four collective, and four ambiguous predicates to be combined with the modifiers under study in affirmative and negative control sentences following this structure: (it is not true that +) argument + predicate + modifier. The tests performed not only showed that the generated sentences were semantically well-formed, but also that, contrary to what had been initially argued, the role of the items ‘junto(s)’ and ‘sozinho(s)’ was not that of anti-distributivity and anti-collectivity modifiers. In the case of ‘junto(s)’, the combination with the predicates showed that the expression functions as a collectivizing item, as previously suggested by Araújo, Palmieri, and Basso (2026), which can take scope over individuals when combined with collective and ambiguous predicates, or over events when combined with distributive predicates. On the other hand, the expression ‘sozinho(s)’ functions, as pointed out by Basso and Rodrigues (2024), as an anti-comitative item that excludes the company of other individuals when combined with different types of predicates. In this sense, the combinatory exercise carried out in this study allowed us not only to better understand the behavior of distributive and collective predicates but, above all, to advance the descriptive analysis of the items ‘junto(s)’ and ‘sozinho(s)’, which have only recently become objects of study in Brazilian Portuguese.
Engenharia de nanoestruturas de óxido de cobre via plasma não térmico para redução eletroquímica de CO2
(Universidade Federal de São Carlos, 2026-07-24) Mestriner, Eloá Rodrigues; Mascaro, Lucia Helena; http://lattes.cnpq.br/9130022476352844; https://lattes.cnpq.br/8219299536584388; Souza, Fernanda de Lourdes; Sitta, Elton Fabiano; http://lattes.cnpq.br/2583849090572828; http://lattes.cnpq.br/4326476348284298
ENGINEERING OF COPPER OXIDE NANOSTRUCTURES VIA NON-THERMAL PLASMA FOR THE ELECTROCHEMICAL REDUCTION OF CO2 investigated the development and optimization of nanostructured electrocatalysts based on copper and CuOx/ZnO, employing defect engineering and structural modification via radio-frequency non-thermal plasma, while evaluating the impact of different gaseous atmospheres. The results demonstrate that post-synthesis modifications on CuOx over metallic mesh optimized the catalytic interface and favored the formation of C2+ products, achieving Faradaic efficiencies (FE) greater than 70%. However, these modulations were limited to the catalyst surface, proving ineffective for suppressing the hydrogen evolution reaction and for the robust propagation of carbon chains. The application of non-thermal plasma treatment prior to the anodization step induced profound structural modifications that extended to the material's bulk, creating preferential nucleation sites. This resulted in a decrease in hydrogen formation rates (FE≤ 25%) and directed C-C coupling routes depending on the gaseous atmosphere. Thus, N2 plasma favored selectivity for n-propanol (FE= 14%), while CO2 plasma stabilized ketones (FE= 7%) and conferred notable integrity to the film. The methodological expansion to CuO/ZnO heterostructures proved that CO2 plasma acts beyond oxidation, serving as an efficient promoter of atomic diffusion and structural consolidation. The controlled incorporation of zinc induced electronic modulation, increasing the electrochemically active surface area, significantly suppressing hydrogen reduction (FE = 11%), favoring the alcohol formation route, primarily ethanol (FE ≥ 25%). Adjusting the plasma exposure time allowed for switching the predominant selectivity between C3 and C2 products. In summary, this work establishes that the synergy between the choice of support, controlled bimetallic integration, and defect induction via non-thermal plasma represents a robust and innovative approach for the rational design of selective catalysts.
Avaliação da segurança viária de ciclistas de Sertãozinho, São Paulo, Brasil, e proposta de ações mitigadoras com base no georreferenciamento de sinistros de trânsito
(Universidade Federal de São Carlos, 2026) Cassanti, Isabella; Monari, Marcelo; http://lattes.cnpq.br/7145992897885055; http://lattes.cnpq.br/5944412594047895; https://orcid.org/0009-0001-9268-5013; https://orcid.org/0000-0002-5562-3235
Os sinistros de trânsito impactam significativamente o número de mortes no Brasil. A mitigação da insegurança viária é especialmente importante para proteger os usuários do transporte ativo, isto é, pedestres e ciclistas, visto que estes representam a parcela de maior vulnerabilidade na rede de transportes. Nesse sentido, registros georreferenciados de sinistros de trânsito são imprescindíveis para a elaboração de diagnósticos de segurança viária e o desenvolvimento de modelos voltados à compreensão dos fatores associados à frequência e à severidade desses eventos, além de subsidiarem a tomada de decisões para a mitigação de ocorrências futuras. O objetivo deste trabalho foi avaliar a segurança viária de ciclistas em um município brasileiro de pequeno porte (Sertãozinho, SP). Para tanto, realizou-se o georreferenciamento em SIG de 13 sinistros fatais e 223 não fatais envolvendo ciclistas no município estudado, filtrados da base de dados abertos do sistema Infosiga-SP para o período de 2015 a 2026, o que permitiu a geração de mapas de densidade de Kernel referentes à concentração desses eventos. A partir dos diagnósticos analítico e espacial, procedeu-se à identificação de 8 pontos críticos a serem auditados em campo e analisados de forma retrospectiva com auxílio do Google Street View, seguida da proposta de intervenções mitigadoras da insegurança viária de ciclistas locais, incluindo técnicas de traffic calming, provisão de infraestrutura cicloviária e adequações na geometria viária. Os resultados sugerem a simplicidade de aplicação do método e o potencial de reprodução em outros locais de estudo que disponham de informações análogas, como os demais municípios paulistas, que são integralmente abrangidos pela plataforma Infosiga-SP. Na cidade de Sertãozinho/SP, os pontos críticos de ocorrência e severidade de sinistros envolvendo ciclistas concentram-se em interseções viárias entre ruas e avenidas de maior hierarquia funcional. Ademais, condições precárias de sinalização e a escassa provisão de infraestrutura cicloviária também contribuem para a persistência desses eventos. Por fim, os sinistros fatais de ciclistas no município ocorrem frequentemente com o envolvimento de veículos pesados, a exemplo de ônibus e caminhões.
Level of Traffic Stress, Urban Pavement Service Index, and road slope combined for the evaluation of a 5-, 10- or 15-minute Neighborhood
(Universidade Federal de São Carlos, 2026) Kodama, Gabriella Mie Hanada; Monari, Marcelo; http://lattes.cnpq.br/7387240110294967; http://lattes.cnpq.br/5944412594047895; https://orcid.org/0009-0000-7863-7405; https://orcid.org/0000-0002-5562-3235
The X-minute Neighborhood (XmN) concept advocates the development of self-sufficient territorial units that encourage active travel, contribute to reducing dependence on private motorized vehicles, and mitigate urban sprawl. Despite its theoretical significance, the concept remains poorly systematized for large-scale application, a limitation largely stemming from the difficulty of developing a universal approach. The objective of this study was to combine key variables influencing bicycle use into a cyclability index to evaluate the adherence of spatial units to the XmN concept. To demonstrate the proposed approach, a case study was conducted in the Cidade Jardim neighborhood of São Carlos, SP, Brazil. The method comprised the geoprocessing of open and field-surveyed spatial data in GIS; georeferencing of bicycle Trip Attractors (TAs); assessment of Level of Traffic Stress (LTS), Urban Pavement Service Index (ISU), and road slope for cyclable road segments under mixed traffic; formulation and calculation of a cyclability index for these segments; and evaluation and mapping of 5mN, 10mN, and 15mN conditions. The results yield a straightforward visual and numerical interpretation of the cyclability potential and the XmN potential of the case study, reflecting an optimistic outlook for the studied neighborhood. However, none of the input variables account for motorized traffic flow when assessing the operational quality of cycling routes. Therefore, care must be taken to complement the proposed approach with methods and techniques that address this variable, such as updated versions of the LTS classification. Furthermore, not all TAs required to fulfill this framework are currently present within the neighborhood.
Diretrizes para implementação de business intelligence no monitoramento contínuo da execução financeira do PROAP na UFSCar
(Universidade Federal de São Carlos, 2026-08-14) Yamamura, Fabiano; Albuquerque, Andrei Aparecido de; http://lattes.cnpq.br/9667573506903226; https://orcid.org/0000-0002-2819-9993; https://lattes.cnpq.br/2244479338567381; https://orcid.org/0009-0004-3577-699X; Silva, Fabio Molina; Brunozi Júnior, Antônio Carlos; http://lattes.cnpq.br/8371146074145702; http://lattes.cnpq.br/0222405169890569; https://orcid.org/0000-0002-0407-1231; https://orcid.org/0000-0001-9372-6246
The dispersion of information in the management of the Graduate Support Program (PROAP) at Federal University of São Carlos (UFSCar) makes it difficult to monitor the integrated budget of this resource within the Institution. This study proposes a way to structure the continuous monitoring of the program´s financial execution based on Business Intelligence (BI) principles. The research is qualitative, in case study format, based mainly on documentary analysis and administrative records related to financial execution. The results show that the definition of Key Performance Indicators (KPIs), data governance and systematic monitoring routines can favor the organization of Integrated Financial Management System of the Federal Government (SIAFI) and Electronic Information System (SEI) records in general information applicable to monitoring. The study resulted in a proposal for a management panel structured in three layers, with nineteen KPIs and documented calculation rules, in addition to an institutional adoption guide that guides its implementation at UFSCar. These products may contribute to improving budget predictability and reducing of dependence on manual controls in the management of PROAP.
