Optimising Legume Integration, Nitrogen Fertilisation, and Irrigation in Semi-A...
Silva, L.; Barbosa, S.; Lidón, F. C.; Maçãs, B.; Faugno, S.; Sannino, M.; Serrano, J.; D'Antonio, P.; Fiorentino, C.; Cellini, F.; Ferreira, P.Monoculture systems depend on high nitrogen (N) fertilisation. Incorporating leg umes into forage crops offers a sustainable alternative with agronomic and economic benefits. This study assesses the impact of legumes in fodder systems, evaluating yield, N use efficiency (NUE), and profitability while identifying the best cropping strategy under semi-arid conditions. The experiment, conducted at Herdade da Comen...
O peso do ensino superior no desenvolvimento económico da União Europeia: uma a...
Rebola, F.; Valente, S.; Marchão, A.; Ferreira, P.; Almeida, D.Este estudo analisa a relação entre a percentagem da população com ensino superior, a densidade populacional e o Produto Interno Bruto per capita (PIBpc) nas regiões da União Europeia (UE), a partir de dados do Eurostat e recorrendo a metodologias estatísticas e econométricas. Em termos gerais, os resultados evidenciam o impacto esperado de ambas as variáveis utilizadas no PIBpc, ainda que com elevados níveis d...

Increased performance of mineral wool based ETICS by components interaction sur...
Cardoso, D.; Flores-Colen, I.; Pereira, M. F. C.; Ferreira, P.; Sequeira, P.; Silva, L.ETICS is widely recognized as a good solution to building façade due to thermal comfort, energy consumption optimization and as good mechanical and aesthetical performance. On the other hand, also presents few limitations, especially when related to fire reaction, unless the insulation material would be mineral wool. Based on this reality, is expected to see an increase of mineral wool as key material to suppor...

Pristine Multi-walled carbon nanotubes for a rapid and efficient plasmid DNA cl...
Ferreira, P.; Riscado, M.; Bernardo, S.; Freire, M.G.; Faria, J.L.; Tavares, A.P.M.; Silva, C.G.; Sousa, F.Therapeutic approaches based on nucleic acids to modulate cell activity have recently gained attention. These molecules arise from complex biotechnological processes, requiring effective manufacturing strategies, high purity, and precise quality control to be used as biopharmaceuticals. One of the most critical and time-consuming steps for nucleic acids-based biotherapeutics manufacturing is their purification,...
The impact of combining SRSD instruction with a brief growth mindset interventi...
Camacho, A.; Alves, R. A.; Silva, M.; Ferreira, P.; Correia, N.; Daniel, J.Self-Regulated Strategy Development (SRSD) is an evidence-based instructional approach combining background knowledge, writing, and self-regulation strategies to improve students’ writing motivation and performance. While the positive impact of SRSD on writing performance variables is well-established, mixed findings were found for motivational variables, namely self-efficacy. In addition, the impact of SRSD on...
Portuguese Sorraia horse dynamics study with innovative technology: three natur...
Faria, RAS; Marques, N.; Ferreira, P.; Sousa, C. V. R.; Correia, R.; Silva, J. A. I. I. V.; Vicente, AntónioPortuguese native Sorraia horse is considered a primitive breed and ancestor of horses in Iberian Peninsula, where they inhabited since the Pleistocene. A closed mating system allowed to maintain the breed standard since its discovery, one century ago. The aim of this study was to characterize the dynamics of 6 Sorraia Stallions, considered very endangered (±300 living animals), using innovative technology equi...
