Journal ArticleDOI
Acute kidney injury in intensive care unit patients: a comparison between the RIFLE and the Acute Kidney Injury Network classifications.
José António Lopes,Paulo R. Fernandes,Sofia Jorge,Sara Gonçalves,António Alvarez,Zélia Costa e Silva,Carlos França,Mateus Martins Prata +7 more
TL;DR: Although AKIN criteria could improve the sensitivity of the acute kidney injury diagnosis, it does not seem to improve on the ability of the RIFLE criteria in predicting inhospital mortality of critically ill patients.
Journal ArticleDOI
A hierarchical model for concurrent material and topology optimisation of three-dimensional structures
TL;DR: In this article, an extension of the hierarchical model for topology optimisation to three-dimensional structures is presented, which covers the simultaneous characterisation of the optimal topology of the structure and the optimal design of the cellular material used in its construction.
Journal ArticleDOI
Permeability analysis of scaffolds for bone tissue engineering
TL;DR: This study showed that permeability encompasses the influence of both porosity and pore size on mass transport, thus indicating its importance as a design parameter and indicates that the mathematical approach used to determine permeability may be useful as a scaffold design tool.
Journal ArticleDOI
A material based model for topology optimization of thermoelastic structures
TL;DR: In this paper, the authors present a computational model for the topology optimization problem of a 2D linear-elastic solid subjected to thermal loads, with a compliance objective function and an isoperimetric constraint on volume.
Journal ArticleDOI
A Model of Bone Adaptation Using a Global Optimisation Criterion Based on the Trajectorial Theory of Wolff.
TL;DR: It is observed that the alignment of principal strains with the material orthotropy direction is, in general, not possible for all load cases, so less restrictive microstructures (nonorthotropic) will yield higher structural stiffnesses than strictly orthotropic microstructure.
