Introduction to the Special Section: Methodological and conceptual challenges i...
Paiva, Francisco; Albuquerque, PaulaThis Speçcial Section of Aniki journal addresses the methodological and conceptual challenges posed to Arts-Based Research in the field of cinematic arts. This type of research, still in consolidation, intersects arts, sciences, and the humanities, proposing an ecology of practices that value creation as a form of knowledge. Practice-based artistic research challenges traditional academic norms by introducing h...
Environmental monitoring and biomarkers of exposure to styrene in chemical indu...
Fernandes, Daniela; Meneses, Márcia; Albuquerque, Paula; Barros, MiguelBiomarkers of exposure to chemicals, such as styrene, allow estimating the exposure to a particular compound by measuring the compound or it(s) metabolite(s) in body fluids. An example is the determination of mandelic acid and phenylglyoxylic acid in urine. Indicators of genotoxicity are categorized as: (a) DNA and protein adducts; (b) DNA strand breaks. Styrene metabolism is initiated by Cytochrome P450 enzyme...
Is online teaching challenging faculty well-being?
Mosquera, Pilar; Albuquerque, Paula; Picoto, WinnieOrganizations that practice Sustainable Human Resource Management are socially responsible and concerned with the safety, health and satisfaction of their employees. Under this sustainability orientation, it is very relevant to analyze whether the sudden transition to e-learning as a strategy of adaptation to the COVID-19 pandemic affected the well-being of faculty. One hundred and two college teachers at a bus...
Risk assessment of welding operations and processes in terms of ultrafine parti...
Gomes, João; Miranda, Rosa M.; Esteves, Helder M.; Albuquerque, PaulaWelding is extensively used in metallic construction worldwide, in spite of being able to produce dangerous fumes that may be hazardous to the welder’s health. It is estimated that, presently, 1-2% of workers from different professional backgrounds (which accounts for more than 3 million persons) are subject to welding fume and gas action. Recently, studies have proved the existence of ultrafine particle emissi...
Characterization of airborne emission of nanoparticles in the ceramic industry ...
Esteves, H.; Bordado, J.; Gomes, João; Miranda, R.; Albuquerque, PaulaThe objective of this study was to evaluate occupational exposure to nanoparticles during some tasks performed in different production processes of different ceramic industries in Portugal, to select the places of greatest occupational exposure through the analysis of the sampled data, to verify what is the pulmonary accumulation in these places, to identify the composition of the released nanoparticles, apply ...

Evaluation of the amount of nanoparticles emitted in LASER additive manufacture...
Gomes, J. F.; Miranda, R.; Oliveira, J. P.; Esteves, H. M.; Albuquerque, PaulaObjectives: The objective of this study was the evaluation of the professional exposure to nanoparticles during tasks performed in workstations for production of metallic parts by laser welding additive manufacturing. Materials and methods: The study was developed in an installed additive manufacturing machine, having controlled temperature and humidity in an industrial unit where metal parts were being produce...

Professional exposure to nanoparticles in the manufacture of parts by laser wel...
Esteves, Helder; Gomes, João; Miranda, Rosa; Albuquerque, PaulaSome studies on occupational exposure to particulates have pointed out to dangerous effects for workers as regards inhalable and respirable particles. These scenarios of occupational exposure are extremely complex since they involve components inherent to individuals, working conditions and the activity itself. The influence of welding fumes on the human body has different effects depending on the composition o...
Exposição profissional a nanopartículas na fabricação de peças por soldadura a ...
Esteves, Hélder; Gomes, João F.; Miranda, R. M.; Albuquerque, PaulaA soldadura é o principal processo industrial utilizado para unir metais. Contudo, pode produzir fumos nocivos para a saúde dos trabalhadores e estima-se que, presentemente, 1-2% de trabalhadores (cerca de mais de 3 milhões), estejam sujeitos à ação de fumos e gases de soldadura. Os riscos inerentes aos processos de soldadura podem ser classificados como riscos decorrentes de agentes físicos e riscos relacionad...
