Physically active bioreactors for tissue engineering applications
Castro, N.; Ribeiro, Sylvie Oliveira; Fernandes, M. M.; Ribeiro, C.; Cardoso, V.; Correia, V.; Minguez, R.; Lanceros-Méndez, S.Tissue engineering (TE) is a strongly expanding research area. TE approaches require biocompatible scaffolds, cells, and different applied stimuli, which altogether mimic the natural tissue microenvironment. Also, the extracellular matrix serves as a structural base for cells and as a source of growth factors and biophysical cues. The 3D characteristics of the microenvironment is one of the most recognized key ...
Organic acids concentration in citrus juice from conventional versus organic fa...
Duarte, Amílcar; Caixeirinho, Dalila da Cruz; Miguel, Maria Graça; Sustelo, V.; Nunes, Carla; Fernandes, M. M.; Marreiros, AntónioEvery day consumers make choices about what to eat and ask themselves “Should I be buying organic food?” For producers, is very important to have technical information about the quality of organic products. It can facilitate to demonstrate the quality of organic products, in comparison with conventional ones. The purpose of our work was to compare internal and external characteristics of citrus, produced in org...
Qualidade de laranjas ‘Navelina’ e ‘Valencia late’ produzidas no modo de produç...
Reis, Duarte; Fernandes, M. M.; Marreiros, António; Mourão, Isabel; Duarte, AmílcarA citricultura no modo de produção biológico (MPB) pode constituir uma alternativa viável relativamente à diminuição do impacte desta actividade agrícola sobre o ambiente, melhorando simultaneamente a qualidade dos frutos. Neste trabalho, realizaram-se dois estudos comparativos com frutos das cultivares ‘Navelina’ e ‘Valencia late’ sujeitos a condições edafo-climáticas idênticas, mas com diferentes modos de pro...
In situ characterization of an old railway platform with DCP
Fortunato, E.; Pinelo, A.; Fernandes, M. M.The elastic stiffness measured in situ is considered a good indicator of the performance of railway platforms. The deformation modulus obtained from the Plate Load Test (PLT) is commonly considered representative of that stiffness. Nevertheless, the PLT is a very expensive and time consuming test. Moreover, it is very difficult to perform when the purpose is to characterize ancient platforms of railway lines th...
