Introduction
During rowing, foot positioning on the foot stretcher is critical to optimise muscle force transmission and boat propulsion. Following the beneficial effects of textured insoles on gait and balance, this study aims at investigating whether passive stimulation of foot mechanoreceptors induced by these insoles may contribute to improving...
Bone decomposition in archaeological contexts is differential and dependent on geological and taphonomic variables. The present work analyses evidences of skeletal diagenesis in 25 inhumations (3 rd -4 th to 5 th -7 th centuries) from the Via XVII necropolis of Bracara Augusta (Braga, Portugal). Bracara Augusta is located in the Minho region, North...
Computational investigations on the effect of Gurney flaps in a NACA 0010 cascade with a 90 o blade angle were carried out using STARCCM+ code. The flaps were positioned at the trailing edge of the blades and were aligned at 45 o and 90 o to the blade chord. The variations in the lift, drag, aerodynamic efficiency and static pressure distributions...
