Circadian and Biological Rhythms in Shift Workers—A Firefighter’s Study
Duarte, I.F.; Pereira, J.; Lima, JPM.; Simões, H.; Pereira, T.; Conde, J.Shift Work contribute to dysregulation of the typical sleep and awake periods that cause circadian distortions, increasing the risk of cardiovascular mortality and morbidity and developing metabolic diseases. Firefighting is a career that demands much of individuals and has a great impact on their health, making it a high-risk job. Objectives: This study aims to characterize shift workers’ blood pressure profil...
Effect of fins and nanoparticles in the discharge performance of PCM thermal st...
Pássaro, João; Rebola, A.; Coelho, Luis Manuel Rodrigues; Conde, J.; Evangelakis, J.A.; Prouskas, C.; Papageorgiou, D. G.; Zisopoulou, A.This work studies the heat exchange process of a latent heat thermal energy storage (LHTES) system equipped with a compact finned tubes heat exchanger (HE) as this is one of the most important aspects of the storage system, the capacity for effectively delivering its stored energy. This work fills in a literature gap for 3D, transient heat transport fluid (HTF) flow models concerning storage systems with phase ...
Numeric study of geothermal borehole heat exchanger enhancement via phase chang...
Pássaro, João; Rebola, A.; Coelho, Luis Manuel Rodrigues; Conde, J.his article addresses the theoretical effect of using geothermal boreholes enhanced with macro-encapsulated phase change materials (PCM) employed with a ground sourced heat pump (GSHP). The aim being the improvement of the heat pump performance through soil temperature stabilisation, taking advantage from the PCM inherent property of changing phase at a constant temperature, that can be matched with the tempera...
