In this context, plasma-transferred arc additive manufacturing (PTA-MA) can produce mechanical components by deposition of overlapped layers using metallic powders, generating the desired geometry without the need for complex molds or a wide range of tools. It is a highly efficient technology, with less generation of industrial rejects, low raw-material waste, and toxic gas-free processing. PTA-MA technology offers the possibility to modify the powders' chemical composition, and by controlling the growth of the layers, it is possible to obtain improved and complex parts in a single production step. The result is the manufacture of mechanical components with higher service life, thus reducing industrial scrap. Although profound changes in manufacturing with this technology are necessary, it also introduces a high potential to increase economic growth and sustainable industrial development. Studies regarding the technical and economic feasibility of new materials, modified powder compositions, in-situ alloying, and functional gradient formations are relevant topics in additive manufacturing. This work used the PTA-AM advantages to process high temperatures alloys, creating chemical composition gradients and mechanical properties, as shown by the results presented and discussed here. Increasing performance in terms of mechanical strength and service life in harsh environments is mandatory to reach higher levels of operational efficiency in various industries, such as power generation, aviation, chemical, petrochemical, and metallurgy. 2021-12-01T00:00:00Z https://hdl.handle.net/1884/92620 Translational theory and practice at the service of the 2030 Agenda for the Sustainable Development Prila Leliza Calado; Allanis Kamily Bona da Costa; Elisama Pereira da Luz; Fernanda Mayumi Fujimoto; Marcely Cristina Vallasky; Tatiana Nohemann da Silva The Scientific Initiation project “Translational theory and practice at the service of the 2030 Agenda for the Sustainable Development” aims to offer opportunities for academic development through research applied to the field of Translation to undergraduate students who have knowledge of the English language. In addition to scientific research focused on Translation, students will have the opportunity to help translate documents within the scope of the United Nations' voluntary action, under the Sustainable Development Goals agenda. In this sense, this project also aims to enable the discovery of a new field for students: the translation activity, which is present not only in business environments, but also in literary and technical fields, among others. Thus, in addition to offering practical training through exposing students to the translation exercise, thus increasing their prior knowledge, this project also aims to present a market niche that often goes unnoticed by students who already have command of the English language, but who never considered the possibility of using this ability in other ways. We live in times when spatial distance and temporal distance are shrinking and borders are disappearing, with the impressive development of communication technologies. Thus, mastering foreign languages ​​is a crucial element in this process and can take our students to higher levels, without, however, forgetting the extreme importance that voluntary action currently assumes. 2021-12-01T00:00:00Z https://hdl.handle.net/1884/92618 Mental health and Instagram use: a Brazilian exploratory study about depression, anxiety and FoMo Evelise Galvão de Carvalho Carvalho; Nadyne Costa Schramme; Elisa De Carvalho Until January 2021, the number of Brazilians with internet access increased 14.2% compared to 2020, totaling 160 million users, from which 150 million are active on social media (Kemp, 2021). The average number of hours Brazilians spend on social networks is 10 hours and 8 minutes, above the global average that is 3 hours and 42 minutes, losing only to the Philippines and Colombia. Literature has shown (Bueno, 2018; Ramzan, 2019; Keyte et al 2020; Bettmann et al., 2021) that surfing the social media can lead to an increase in depression, anxiety and FoMo symptoms. Aiming to assess the incidence of these symptoms in the Brazilian context, this study carried out a quantitative survey with users of Instagram, worldly the fourth most used network behind Facebook, YouTube, and WhatsApp (Statista, 2021). We divided respondents into three groups: Instagram users with an average of >5h daily (G1); Instagram users <2h daily (G2), and non-users of Instagram (G3). During the data collection, participants responded to three questionnaires, being: Patient Health (PHQ-9), General Anxiety Disorder (GAD-7), and Fear of missing out scale. Evidence shows that G1 had a higher incidence of depression and anxiety symptoms than the other groups. However, further studies should be conducted to confirm this hypothesis. This study aimed to contribute to building knowledge in the field of technology and mental health, as well as raise awareness of the importance of implementing initiatives to promote a healthier use of social media. 2021-12-01T00:00:00Z
