Urinary Estrogen Metabolites and Self-Reported Infertility in Women Infected wi...
Santos, J.; Gouveia, M.J.; Vale, N.; Delgado, M. de L.; Gonçalves, A.; da Silva, J.M.; Oliveira, C.; Xavier, P.; Gomes, P.; Santos, L.L.; Lopes, C.Schistosomiasis is a neglected tropical disease, endemic in 76 countries, that afflicts more than 240 million people. The impact of schistosomiasis on infertility may be underestimated according to recent literature. Extracts of Schistosoma haematobium include estrogen-like metabolites termed catechol-estrogens that down regulate estrogen receptors alpha and beta in estrogen responsive cells. In addition, schis...
Fatigue behaviour of AA6082-T6 MIG welded butt joints improved by friction stir...
Silva, J. da; Costa, J. M.; Loureiro, A.; Ferreira, J. M.Friction Stir Processing (FSP) was based on the principles of Friction Stir Welding (FSW), a solid-state joining process originally developed for aluminium alloys. It is an emerging metalworking technique which can provide localized modification and control of microstructures in near-surface layers of processed metallic components. In this research, FSP appears as an alternative to traditional methods for fatig...
Object-oriented and distributed approach for programming robotic manufacturing ...
Pires, J. Norberto; Sá da Costa, J. M. G.Flexible manufacturing systems (FMS) are essential for small/medium batch and job shop manufacturing. These types of production systems are used to manufacture a considerable variety of products with medium/small production volumes. Therefore, the manufacturing platforms supporting these types of production must be flexible and organized in flexible manufacturing cells (FMC). Programming FMCs remains a difficul...
