Fernandes, T. R. C.; Machado, A. S. Reis; Condeço, J.; Rangel, C. M.; Pardal, T.This work addresses the scaling up of a system for electrochemical reduction of CO2 to produce hydrocarbons that can be used as fuel for a regenerative energy storage cycle. Challenges involved in such a task are mentioned. Scalingup results of a system based on electrodes of high surface area with modified copper deposits are described. Current densities around 100 mA/cm2 were obtained. This corresponds to the...
The seroprevalence for hepatitis E viral antibodies in the northern region of P...
Queirós, L; Instituto Português de Sangue, Centro Regional do Porto.; Condeço, J; Tender, A; Mateus, M; Teixeira, A; Pascoal, HThe authors have undertaken a study in the north of Portugal in what concerns the prevalence of antibodies for HEV donors. This study was transverse through observation and survey. A sample of 1.473 donors was randomly selected from among the population of donors of the Oporto Regional Blood Centre. This sample was representative of the northern region and stratified by district. The usual EIA method has been u...
