Methodology for Bone–Implant Stiffness Evaluation
Rosa, Natacha; Tavares, Sérgio; Carbas, Ricardo; Simoes, Ricardo; Magalhães, F.; Marques, AntónioBackground It has been difficult to improve the intramedullary nail technique because of the lack of consistency in the procedures used to evaluate the bone-implant stiffness. Objective The goal of this study was to develop a simple methodology for determining the stiffness of a bone implant that considers the physiological loads and bone orientation, and allows a finite element analysis and its validation usin...
Preparation of robust polyamide microcapsules by interfacial polycondensation o...
Rosa, Natacha; Martins, Gabriela V.; Bastos, Margarida M S M; Gois, Joana R.; Coelho, Jorge F. J.; Marques, Juliana Filipa Gouveia; Tavares, C. J.Microcapsules produced by interfacial polycondensation of p-phenylenediamine (PPD) and sebacoyl chloride (SC) were studied. The products were characterized in terms of morphology, mean diameter and effectiveness of dodecane encapsulation. The use of Tween 20 as dispersion stabilizer, in comparison with polyvinyl alcohol (PVA), reduced considerably the mean diameter of the microcapsules and originated smoother w...
Physical consequences of falls in the elderly: a literature review from 1995 to...
Terroso, Miguel; Rosa, Natacha; Marques, António Torres; Simões, RicardoIn the last decade, population ageing has been registered as a global phenomenon. A relation exists between falling and ageing, since falling frequency increases significantly with age. In fact, one in three older adult falls annually. Although ageing is generically associated with decrease and degeneration of psychological and physical functions, it is still not common for the correct identification of risk fa...
