- Online holistic program to foster health amongst students: a pilot study in a Portuguese university during COVID-19 pandemicPublication . Veiga, Elisa; Duarte, Raquel; Capela, Inês; Pinto, Elisabete; Silva, Margarida; Sá, Cristina; Sá, Luís; Kunz, Sahra; Serra, Sofia; Pereira, Henrique; Machado, Bárbara C.; Gomes, Ana; Pimenta, Ana; Almeida, Armando; Silva, Patrícia O.; Correia, MartaDuring the COVID-19 pandemic, several preventive mental health interventions took place to increase the psychological well-being of university students due to the high levels of stress, anxiety and negative emotions experienced in that period. This context reinforced the role of universities in supporting students and preventing the mental health risk factors they faced. In this context a multidisciplinary team of professionals (psychologists, nurses, nutritionists, and artists) in the Portuguese Catholic University, gathered efforts and developed an holistic intervention program for university students based on a mind and body integrated approach. This program of 8 online sessions aims to improve students’ resilience to the psychosocial consequences of COVID-19 pandemic and promote their wellbeing. The twenty university students that participated in this pilot study reported that this intervention improved their emotional self-awareness, their ability to apply self-care strategies, as well as they believed it promoted healthier lifestyle changes. These findings suggest that this program consists in an innovative approach with the potential to promote the psychological health and well-being of university students in adverse circumstances.
- Art casting in Portuguese 19th century industrial foundries: a multi-analytical study of an emblematic copper-based alloy monumentPublication . General-Toro, Pablo; Bordalo, Rui; Moreira, Patrícia Raquel; Vieira, Eduarda; Brunetti, Antonio; Iannaccone, Roberta; Bottaini, CarloThe outdoor sculpture of the first Portuguese king, D. Afonso Henriques (~1109 – 1185 AD), placed in Guimarães (North Portugal) is one of the most emblematic national sculptures. Created in 1887 by António Soares dos Reis, it possesses a remarkable symbolic value in the presumed birthplace of the king. In addition to the artistic and heritage importance of the monument, it is one of the few sculptures cast by a Portuguese industrial foundry in the 19th-century. This study obtained data on the sculpture's elemental composition and corrosion products, gathering important historical and technical information. For this purpose, a multi-analytical approach consisting of X-ray fluorescence (XRF), X-ray diffraction (XRD), optical microscopy (OM) and scanning electron microscopy (SEM-EDS) was carried out to characterise the bulk metal and corrosion layers. The data revealed a ternary alloy of Cu, Sn, Zn with Pb, Fe, As, Bi and Mn as minor elements. The alloy matches that of other sculptures cast in that period. In terms of corrosion, it is characterised by the presence of oxides. These results represent the first step for applying an appropriate conservation strategy for bronze sculptures with similar characteristics.
