Cork Liquefaction for Polyurethane Foam Prodution
Esteves, Bruno; Dulyanska, Yuliya; Costa, Catarina; Vicente, Jose; Domingos, Idalina; Pereira, Helena; Lemos, Luis; Cruz-Lopes, LuísaCork is one of the most important forest products in Portugal. The cork processing industry is highly resource-efficient, with the only residue, cork powder, which is too minor in quantity for agglomerate production. This work studied the usage of cork powder for the production of added-value products via polyol liquefaction. Liquefactions were performed in a reactor using a mixture of polyethylene glycol (PEG ...

Predicting progression of mild cognitive impairment to dementia using neuropsyc...
Pereira, Telma; Lemos, Luis; Cardoso, Sandra; Silva, Dina; Rodrigues, Ana; Santana, Isabel; de Mendonca, Alexandre; Guerreiro, Manuela; Madeira, Sara C.Background: Predicting progression from a stage of Mild Cognitive Impairment to dementia is a major pursuit in current research. It is broadly accepted that cognition declines with a continuum between MCI and dementia. As such, cohorts of MCI patients are usually heterogeneous, containing patients at different stages of the neurodegenerative process. This hampers the prognostic task. Nevertheless, when learning...
A Framework for Implementing Radiation-Tolerant Circuits on Reconfigurable FPGAs
Gericota, Manuel G.; Alves, Gustavo R.; Lemos, Luis; Ferreira, José M.The outstanding versatility of SRAM-based FPGAs make them the preferred choice for implementing complex customizable circuits. To increase the amount of logic available, manufacturers are using nanometric technologies to boost logic density and reduce prices. However, the use of nanometric scales also makes FPGAs particularly vulnerable to radiation-induced faults, especially because of the increasing amount of...
Recommendations for initial therapy of acute otitis media
Lemos, Luis; Xavier, BilhotaThe abuse use of antibiotics has led to gradual emergence of bacterial resistance. It is known, moreover, that 80 to 90% of acute otitis media favorably develop spontaneously and in a short time.; O abuso da utilização de antibióticos levou ao aparecimento progressivo de resistências bacterianas. Sabe-se, por outro lado, que 80 a 90% das otites médias agudas evoluem espontaneamente de modo favorável e num curto...
