Effect of wearing a swimsuit on hydrodynamic drag of swimmer BABT
Marinho,Daniel Almeida; Mantha,Vishveshwar Rajendra; Vilas-Boas,João Paulo; Ramos,Rui Jorge; Machado,Leandro; Rouboa,Abel Ilah; Silva,António José.
The purpose of this study was to analyse the effect of wearing a swimsuit on swimmer's passive drag. A computational fluid dynamics analysis was carried out to determine the hydrodynamic drag of a female swimmer's model (i) wearing a standard swimsuit; (ii) wearing a last generation swimsuit and; (iii) with no swimsuit, wearing light underwear. The three-dimensional surface geometry of a female swimmer's model with different swimsuit/underwear was acquired through standard commercial laser scanner. Passive drag force and drag coefficient were computed with the swimmer in a prone position. Higher hydrodynamic drag values were determined when the swimmer was with no swimsuit in comparison with the situation when the swimmer was wearing a swimsuit. The last...

Learning Human Anatomy Using Three-Dimensional Models Made from Real-Scale Bone Pieces: Experience with the Knee Joint among Pre-Service Biology Teachers International Journal of Morphology
Lizana,Pablo A; Merino,Cristian; Bassaber,Arlette; Henríquez,Ricardo; Vega-Fernández,G; Binvignat,Octavio.
This study aims to assess the efficiency of using real-scale knee models to learn about the locomotor system. Participants included a total of thirty-nine second year students in a Human Anatomy class of a Biology Teaching course. One week before the intervention, a pre-test was administered to assess the students' prior knowledge. The pre-service biology teachers were provided with a real-scale plaster model of a knee bone and were subsequently required to identify and create their own model of bone, joint and muscle elements. At the end of the intervention, a post-test was performed and opinion survey, in addition to a comparison with other locomotor system structures (four images: knee joint, muscular component of lower limb, shoulder joint and pelvic...
