Finding Out The Neurological Consequences Of Covid-19
Alves, A.I.; Freitas, C.; Viveiros, A.; Ribeiro, L.; Faria, S.; Freitas, D.; Faria, R.; Faria, J.t- Introduction: Since the first official case of COVID-19 in China in December 2019, researchers have been trying to uncover the mechanism of action of the severe acute respiratory syndrome Coronavirus 2 (Sars-CoV-2), which attacks several organs in addition to the lungs and causes circulatory changes that can lead to death not only from lung failure but also due to commitment of other organs. Objective: The a...
Internova e-learning platform in an entrepreneurial context
Araújo, I.; Pinheiro, Rita; Faria, P. M.; Azevedo, J. N.; Faria, S.; Velho, M. V.Currently, there is still an opposition of teachers to the implementation of new technologies in an educational context. Although several studies point out the relevance of the use of information and communication technologies in pedagogical practices, providing educational contexts more focused on learning practices and fostering more active and autonomous professionals. In this context, this article emphasize...
Can ankle anticipatory postural adjustments associated with gait initiation be ...
Pereira, S.; Silva, A.; Silva, C.; Sousa, A.; Gomes, J.; Faria, S.; Santos, RubimPostural control is a complex ability of the central nervous system, fundamental prerequisite in several motor programs, that is often compromised after central nervous system injury, particularly in ischemic events involving the middle cerebral artery. Stroke in this territory frequently compromise cortical output from pre-motor and supplementary motor areas and their connectivity with subcortical structures s...
A study on the production of thin-walled Ti6Al4V parts by selective laser melting
Miranda, G.; Faria, S.; Bartolomeu, F.; Pinto, E.; Alves, N.; Peixinho, N.; Gasik, M.; Silva, F.S.Selective Laser Melting (SLM) is an extremely versatile technology especially suited for the manufacturing of thin-walled parts. Micro-sized parts are highly influenced and dependent on the SLM processing parameters; thus being indispensable to assess the influence of processing parameters on SLM fabrication, as isolated parameters but also their interactions. In this study, the influence of SLM laser power and...
The functionalization of natural polymer-coated gold nanoparticles to carry bFG...
Ferreira, H.; Martins, A.; Silva, M. L. A.; Amorim, S.; Faria, S.; Pires, R. A.; Reis, R. L.; Neves, N. M.Gold nanoparticles (AuNPs) enable the treatment and real-time monitoring of several diseases, providing an exciting and advantageous nanomedicine strategy. These NPs have therefore been adequately functionalized to enable them to carry growth factors (GF), namely basic fibroblastic (bF) GF, which play an essential role in different and important cellular processes including cellular proliferation, survival, mig...
Anxiety and burnout in young athletes: The mediating role of cognitive appraisal
Gomes, A. Rui; Faria, S.; Vilela, C.This study tested the relationship between trait anxiety, cognitive appraisal, and athletes’ burnout proposing two hypotheses: (a) there is a direct relationship between athletes’ trait anxiety and cognitive appraisal and burnout; and (b) cognitive appraisal mediates the relationship between trait anxiety and burnout and this mediation occurs despite the competitive level and sport records of athletes. The stud...
Dual release of a hydrophilic and a hydrophobic osteogenic factor from a single...
Monteiro, N.; Martins, A.; Pires, R. A.; Faria, S.; Fonseca, N. A.; Moreira, J. N.; Reis, R. L.; Neves, N. M.Delivery systems may be designed to protect and control the release kinetics of growth/differentiation factors in a spatiotemporal manner. Liposomes are examples of biological-based bioactive agent delivery systems. In this work, ascorbic acid (AscA) was encapsulated in the inner compartment of the liposome and dexamethasone (Dex) was encapsulated within the lipid bilayer in order to develop a dual release syst...
Predictive models for physical and mechanical properties of 316L stainless stee...
Miranda, G.; Faria, S.; Bartolomeu, F.; Pinto, Elodie; Madeira, S.; Mateus, Artur; P.Carreira; Alves, Nuno; Silva, F.S.; Carvalho, O.Selective Laser Melting (SLM) processing parameters are known to greatly influence 316L stainless steel final properties. A simple energy density calculation is insufficient for explaining mechanical and physical properties as well as microstructural characteristics, which are known to significantly influence these parts performance. In fact, parts produced by using different combinations of processing paramete...
Predictive models for physical and mechanical properties of Ti6Al4V produced by...
Bartolomeu, F.; Faria, S.; Carvalho, O.; Pinto, E.; Alves, Nuno; Silva, F.S.; Miranda, G.The properties of parts produced by Selective Laser Melting (SLM) are highly influenced by the processing parameters. The calculation of the energy density is not enough for justifying the mechanical and physical properties, and understand the microstructures of Ti6Al4V samples produced by SLM. In fact, samples produced with the same energy density, but with different processing parameters, present distinct pro...
Light field HEVC-based image coding using locally linear embedding and self-sim...
Monteiro, R.; Lucas, L.; Conti, C.; Nunes, P.; Rodrigues, N.; Faria, S.; Pagliari, C.; Silva, E.; Soares, L.Light field imaging is a promising new technology that allows the user not only to change the focus and perspective after taking a picture, as well as to generate 3D content, among other applications. However, light field images are characterized by large amounts of data and there is a lack of coding tools to efficiently encode this type of content. Therefore, this paper proposes the addition of two new predict...
