Marquez, A; Costa, PA complexidade de determinadas patologias clínicas, com necessidade em ambulatório, de apoio de profissionais diferenciados e especializados, conduziu à adopção de medidas alternativas de suporte clínico que respondam de forma mais eficaz às necessidades da Criança e Família. Assim, a ligação entre Cuidados Hospitalares e Domiciliários é actualmente uma exigência. Apoiando iniciativas que promovem a excelência ...
Experimental characterization of a low-current cutting torch
Kelly,H.; Mancinelli,B.; Prevosto,L.; Minotti,F.O.; Márquez,A.An experimental characterization of a low-current (30-40 A) cutting torch is presented. To avoid contamination of the plasma arc by removed anode material, a rotating steel cylinder was used as the anode and the arc was anchored onto the cylinder lateral surface. The cathode-anode and cathode-nozzle voltage drops, together with the gas pressure in the plenum chamber were registered for different values of the m...
Characterization of a quarter torus filter for vacuum arc ion flux transmission
Kelly,H.; Márquez,A.; Pirrera,M.Measurements on the ion flux transmission in a magnetically filtered d-c vacuum arc are presented. The device includes a metallic plasma-generating chamber with water-cooled electrodes coupled to a substrate chamber through a quarter-torus magnetic filter. It is employed a Copper cathode (6 cm in diameter) with a Copper annular anode. The filter consists in a steel cylinder 500 mm length and 100 mm inner diamet...
Modelado numérico del socavado lateral en procesos de soldadura
Cassanelli,A.; Márquez,A.; Lombera,G.; De Vedia,L.A.When welded joints have to meet particular requirements related to fatigue life they are usually designed using the so called S-N design curves. This implies the construction of a curve for each particular design. From the point of view of the user, it is often difficult to establish accurately which is the curve that better fits the design that is being considered. The so called " local approach " is based on ...
