    (Universidade Federal de Goiás, 2025-10-02) Reis, Cleyber Bezerra dos; Ribeiro, Maria do Rosário Campos; http://lattes.cnpq.br/1285706867893743; Oliveira Júnior, Antonio Carlos de; http://lattes.cnpq.br/3148813459575445; Oliveira Júnior, Antonio Carlos de; http://lattes.cnpq.br/3148813459575445; Ribeiro, Maria do Rosário Campos; http://lattes.cnpq.br/1285706867893743; Moreira Júnior, Waldir Aranha; http://lattes.cnpq.br/4552403112118292; Lopes, Victor Hugo Lázaro; http://lattes.cnpq.br/8690054906597785
    Split Learning (SL) is a collaborative learning technique in which a neural network model is partitioned between client and server, enabling training without the need to share the original data. This study investigates the integration of SL with B5G/6G mobile networks using the ns-3 simulator and a convolutional neural network (CNN) trained on the MNIST dataset. We evaluated model-performance metrics, such as accuracy, as well as network indicators including packet loss, latency, throughput, and energy consumption. The results demonstrate that increasing transmit power reduces latency and improves model accuracy. The SL model exhibited performance variability with distance but maintained satisfactory accuracy (>80%) at distances up to 160 m in the highest-power scenario. These findings demonstrate the viability of SL as an enabling technology for next-generation mobile networks, optimising distributed training in communicationconstrained settings.

    O livro da paz da mulher angolana: as narrativas testemunhais das heroínas do povo (1961 - 2008)
    (Universidade Federal de Goiás, 2025-09-30) Prado, Patrícia Martins Alves do; Oliveira, Alcilene Cavalcante de; http://lattes.cnpq.br/0849650918660622; Oliveira, Alcilene Cavalcante de; Pinto, João Alberto da Costa; Silva, Dayane Augusta Santos da
    At first, our concern was to understand how Angolan women were integrated into the political project of forming the Angolan nation. Thus, we present as a working proposal an interpretation of women’s unequal access to national citizenship based on O Livro da Paz da mulher angolana: As heroínas sem nome (2008). Beyond the process of cultural mediation—through semistructured interviews conducted by the Non-Governmental Organization Norwegian People’s Aid (hereafter NGO NPA) - the women who gave their testimony speak for themselves and expose the violence they have suffered. Thus, we consider the fragments of memory in O Livro da Paz da mulher angolana: As heroínas sem nome to be life experiences narrated in the form of testimonial literature. The feminine experiences recalled in these narratives provide clues and evidence that support our understanding of social roles and how women perceive their place in Angolan society after the country’s long history of the national liberation struggle. The documentary corpus reveals social relations stigmatized by gender inequality and female resistance to various forms of violence. We understand that O Livro da Paz da mulher angolana: As heroínas sem nome (2008) presents a perspective from ordinary women, heroines of the people, as survivors of a long period of wars—women who undertake and rebuild both their own lives and the country itself. In this documentary and bibliographical research of a qualitative nature, we seek to methodologically apply the theory of testimonial literature due to the nature of the source. For this purpose, we used the technique of creating an explanatory framework of the testimonial narratives to support the data collection and analysis. The main theoretical and methodological contributions were the intellectual works of the following authors: Sylvia Walby (2000; Maria Lugones (2020); Márcio Seligmann-Silva (1998;2005;2022); Aleida Assmann (2011), among others. The testimonies of Angolan women in O Livro da Paz da mulher angolana: As heroínas sem nome contribute to the construction of historical knowledge. However, this is not a defense of absolute truth, but rather of how the subjects of their own history understand their social and cultural reality. And in this context, they intervene by advocating for behavioral change, including the introduction of female-led sexual re-education for men. In this way, changes in thought are evidenced, producing new meanings and significance for the place of women in Angolan society. Thus, through the plural voices of Angolan women in O Livro da Paz da mulher angolana: As heroínas sem nome (2008), we present as the result of our research a cultural memory of the heroine as a legacy of the struggle for freedom and emancipation in Angola. We defend the genealogy of the archetype of the heroine as a political and cultural artifact of Angola’s modern nationalism, constructed after the country’s political independence.

    Nem recôncavo, nem reconvexo: o movimento Tropicália como prática cultural brasileira e seus pontos de interseção com o samba e com a tradição da música popular brasileira
    (Universidade Federal de Goiás, 2025-09-09) Teixeira, Davi Ebenezer Ribeiro da Costa; Nazareno, Elias; http://lattes.cnpq.br/1486334927436240; Nazareno, Elias; Mello, Maria Therezinha Ferraz Negrão de; Clímaco, Magda de Miranda; Rosa, Robervaldo Linhares; Abdala Junior, Roberto
    This thesis set out to research the Tropicália or Tropicalismo movement, presenting its points of intersection with the Brazilian Popular Music scene in the late 1960s and early 1970s. It sought to understand the proposal of tropicalist songs with reference to the musical heritage of tropicalists Caetano Veloso, Gilberto Gil, and Tom Zé, as well as their ways of thinking about Brazilian culture and popular music. It was observed that these tropicalists constantly refer to certain musical genres, such as samba and bossa nova, and that these genres represent a tradition or foundation of Brazilian Popular Music. With this consideration, the existence of two traditions in Brazilian culture was conceived: an “ancestral” tradition, less perceived and noticed, and another, more present and evident in the musical scene in which MPB is inserted. Based on musical analyses and listening to some tropicalist songs, such as Tropicália, by Caetano Veloso, and Domingo no parque, by Gilberto Gil, it was found that the diversity presented by this song is related to the proposal to establish dialogues within the Tropicália movement. Thus, the two traditions pointed out in the cultural fabric coexist in the sound structure of tropicalist songs. Given this perception of a non-hierarchical approach to musical genres and styles on the part of the tropicalists, the research demonstrated points of convergence and divergence between the Tropicália movement and Brazilian Popular Music at that period. To investigate the musical scene of the time, a broad methodology was sought, covering bibliographic and documentary research, interviews available in newspapers, magazines, and streaming services, as well as analysis and interpretation of some selected musical productions, always observing the interaction that the chosen musical practices, including tropicalist songs, establish with the Brazilian historical-cultural scene. Among some considerations, from points of intersection between Tropicália and Brazilian Popular Music, it was found that the tropicalists converged with MPB in recognizing samba and bossa nova as genres representing a more notable tradition in the cultural scene. However, in seeking to avoid the hierarchization of musical genres and styles, the tropicalists fought against the elitism of MPB that was established at the time.

    Desenvolvimento de filmes bioativos contendo probiótico (Lacticaseibacillus rhamnousus GG.) e polpa de mirtilo (Vaccinium myrtillus)
    (Universidade Federal de Goiás, 2025-09-17) Sousa, Bárbara Nadinne Nepomoceno de; Oliveira Filho, Josemar Gonçalves de; http://lattes.cnpq.br/883104577882707; Egea, Mariana Buranelo; http://lattes.cnpq.br/2608350008080000; Egea, Mariana Buranelo; http://lattes.cnpq.br/2608350008080000; Briceno, Julio Cesar Colivet; http://lattes.cnpq.br/3125238514015541; Yamashita, Fabio; http://lattes.cnpq.br/2462623168172176
    The growing demand for functional foods, driven by the pursuit of healthier eating habits, has brought attention to ingredients such as blueberry (Vaccinium myrtillus), a fruit rich in bioactive compounds like anthocyanins, which exhibit remarkable antioxidant and therapeutic properties. In this context, the incorporation of active components into edible films has been widely studied as an effective and practical method for delivering these substances in a stable form. Aligned with this trend, the use of probiotics in such films aims not only to ensure their viability but also to add nutritional value. This study aimed to develop bioactive films based on carboxymethylcellulose (CMC), the probiotic Lacticaseibacillus rhamnosus GG, and freezedried blueberry pulp. The purpose of these films is to act as carriers for the delivery of functional compounds. To assess their effectiveness, the films were characterized in terms of morphology, moisture content, solubility, water vapor permeability, thickness, vitamin C content, anthocyanins, color, and mechanical properties. In addition, the viability of the probiotic was analyzed over 45 days at storage temperatures of 4°C and 25°C. The incorporation of blueberry pulp influenced not only the physical and optical characteristics but also endowed the films with bioactive properties, such as increased vitamin C content. A reduction in water solubility and an increase in film thickness were observed features that are desirable for protective barrier applications. However, a decrease in mechanical strength and an increase in water vapor permeability were also noted. These changes may be related to the irregular structure observed in the micrographs, suggesting greater diffusivity of water molecules. The addition of the probiotic L. rhamnosus GG represented a functional advantage for the films, with the potential to contribute to human health benefits.
