Comparative Analysis of Pressure Platform and Insole Devices for Plantar Pressu...
Amaro, Catarina M.; Paulino, Maria F.; Valvez, Sara; Roseiro, Luis; Castro, Maria António; Amaro, Ana M.Foot plantar pressure refers to the pressure or force that the foot generates in contact with the ground, varying across different regions of the foot. This parameter is essential in static and dynamic analyses to access accurate diagnoses, study the human body biomechanics, create functional footwear designs, aid in rehabilitation and physiotherapy, and prevent injuries in athletes during sports practice. This...
Effects of Different Basketball Shooting Positions and Distances on Gaze Behavi...
Amaro, Catarina M.; Amaro, Ana M.; Gomes, Beatriz B.; Castro, Maria António; Mendes, RuiBasketball is a sport where in order to obtain points, it is necessary to put the ball in the basket. Therefore, basketball players need to shoot the ball accurately. This study aimed to evaluate if there are differences between shooting positions and angles concerning athlete visual behavior. Tobii Pro Glasses 3 was used to measure the number and duration of fixations in the target during shooting movement. Th...
Understanding Atherosclerosis Pathophysiology: Can Additive Manufacturing Be He...
Henriques, Joana; Amaro, Ana M.; Piedade, Ana P.Atherosclerosis is one of the leading causes of death worldwide. Although this subject arouses much interest, there are limitations associated with the biomechanical investigation done in atherosclerotic tissues, namely the unstandardized tests for the mechanical characterization of these tissues and the inherent non-consensual results obtained. The variability of tests and typologies of samples hampers direct ...
Effect of austempering temperature on microstructure and cyclic deformation beh...
Long, X. Y.; Branco, R.; Macek, W.; Masoudi Nejad, R.; Lesiuk, G.; Zhu, S. P.; Amaro, Ana M.This paper examined the cyclic deformation behaviour of multiphase low-carbon steel that was subjected to austempering heat treatments at four temperatures (190 °C, 230 °C, 275 °C, and 315 °C) below the martensite start temperature (Ms = 353 °C). The tests were conducted at room temperature, under fully reversed strain-controlled conditions, with strain amplitudes in the range 0.5–1.0%. The microstructure was o...
Monotonic and fatigue behaviour of notched glass fibre-reinforced polymer lamin...
Vidinha, H.; Branco, R.; Amaro, Ana M.; Neto, M. A.; Reis, P. N. B.; Costa, J.D.M.This paper studies the monotonic and fatigue behaviour of notched glass fibre-reinforced polymers after long-term exposure in seawater. Uniaxial quasi-static tensile tests and uniaxial stress-controlled cyclic tests were carried out for different immersion times, ranging from 0 days to 910 days, using rectangular cross-section specimens with a central hole. The geometric discontinuity was monitored, via digital...
Computational Flow Dynamic Analysis in Left Atrial Appendage Thrombus Formation...
Valvez, Sara; Oliveira-Santos, Manuel; Piedade, A. P.; Gonçalves, Lino; Amaro, Ana M.Atrial fibrillation (AF) is a common cardiac arrhythmia characterized by irregular and rapid electrical activity in the atria, leading to ineffective contraction and poor blood flow. More than 90% of the left atrial (LA) thrombi that cause thromboembolic events during atrial fibrillation (AF) develop in the left atrial appendage (LAA). AF modifies the hemodynamics of the left atrium, which can result in thrombo...
Joining of Fibre-Reinforced Thermoplastic Polymer Composites by Friction Stir W...
Pereira, Miguel A. R.; Galvão, Ivan; Costa, José Domingos; Amaro, Ana M.; Leal, Rui M.The objective of the current work is to show the potential of the friction stir welding (FSW) and its variants to join fibre-reinforced thermoplastic polymer (FRTP) composites. To accomplish that, the FSW technique and two other important variants, the friction stir spot welding (FSSW) and the refill friction stir spot welding (RFSSW), are presented and explained in a brief but complete way. Since the joining o...
Evaluation of Bone Consolidation in External Fixation with an Electromechanical...
Paulino, Maria F.; Roseiro, Luís M.; Balacó, Inês; Neto, Maria A.; Amaro, Ana M.The monitoring of fracture or osteotomy healing is vital for orthopedists to help advise, if necessary, secondary treatments for improving healing outcomes and minimizing patient suffering. It has been decades since osteotomy stiffness has been identified as one main parameter to quantify and qualify the outcome of a regenerated callus. Still, radiographic imaging remains the current standard diagnostic techniq...
3D Printing of Polymeric Bioresorbable Stents: A Strategy to Improve Both Cellu...
Sousa, Ana M.; Amaro, Ana M.; Piedade, Ana P.One of the leading causes of death is cardiovascular disease, and the most common cardiovascular disease is coronary artery disease. Percutaneous coronary intervention and vascular stents have emerged as a solution to treat coronary artery disease. Nowadays, several types of vascular stents share the same purpose: to reduce the percentage of restenosis, thrombosis, and neointimal hyperplasia and supply mechanic...
Effect of Friction Stir Welding Techniques and Parameters on Polymers Joint Eff...
Pereira, Miguel A. R.; Amaro, Ana M.; Reis, Paulo N. B.; Loureiro, AltinoThe objective of current work is to analyse the influence of different welding techniques and welding parameters on the morphology and mechanical strength of friction stir welds (FSW) in polymers, based on data collected in the literature. In the current work, only articles that provide data on the joint efficiency, or sufficient information to estimate it are considered. The process using conventional tool is ...
