Study on the valorization routes of ashes from thermoelectric power plants work...
Barbosa, Rui Pedro FernandesThesis submitted to obtain the Doctoral degree in Energy and Bioenergy ; The main objective of this thesis was to study new valorization routes of ashes produced in combustion and co-combustion processes. Three main valorization pathways were analyzed: (i)production of cement mortars, (ii) production of concretes, and (iii) use as chemical agents to remove contaminants from wastewaters. Firstly, the ashes prod...

Fuel age, weather and burn probability in Portugal
Fernandes, Paulo; Loureiro, Carlos; Magalhães, Marco; Ferreira, Pedro; Fernandes, ManuelThe relative influence of the factors acting upon burn probability, namely fuel and weather, is not well understood, especially in Europe. We use a digital fire atlas (1975-2008) and apply survival analysis to individual fires (1998-2008) to describe how burn probability changes with fuel age in Portugal. The typical FRI (fire return interval) and median fire-free interval vary regionally from 23 to 52 and 18 t...
Effect of calcium oxide microstructure on the diffusion of isotopes
Ramos, João Pedro FernandesCalcium oxide (CaO) powder targets have been successfully used at CERN-ISOLDE to produce neutron deficient exotic argon and carbon isotopes under proton irradiation at high temperatures (>1000oC). These targets outperform the other related targets for the production of the same beams. However, they presented either slow release rates (yields) from the beginning or a rapid decrease over time. This problem was be...
