In this study, laminar flow forced convection heat transfer of a non-Newtonian nanofluid flowing inside a Micro conduit that is subjected to a constant wall temperature was investigated. By considering the effect of viscous dissipation. The effects of Brinkman numbers (Br), power low index (n) and nanoparticle concentrations (φ) on the developing temperature fields and the local Nusselt number were examined. The obtained results were validated with available solutions for the special cases of conventional fluids (φ = 0) and non-viscous dissipation effect (Br = 0). Bulk temperature distribution and local Nusselt number are presented graphically for Br = 0, 0.5, 1, -0.5 and 1 for non-Newtonian fluids described by the power-law model with the flow index n = 0.3, 1.0 and 3.0. The Nusselt numbers of nanofluids were obtained for different Al2O3 nanoparticle concentrations as well as various Brinkman numbers. [ABSTRACT FROM AUTHOR]

À ce jour, il existe relativement peu d'études concernant la rééducation cardiaque chez le sujet très âgé, en particulier de 80 ans et plus. La plupart des études de la littérature incluent des patients de plus de 65 ans, mais avec un âge moyen compris entre 70 et 75 ans. Ces dernières montrent que la rééducation cardiaque réduit la mortalité, les réadmissions à l'hôpital, les coûts et améliore la capacité d'exercice, la qualité de vie et le bien-être psychologique. Notre expérience personnelle, à propos de trente-huit patients âgés de plus de 80 ans, va dans le même sens. Elle documente l'intérêt de la rééducation cardiaque en termes d'autonomie, de bien-être, de capacités physiques et de qualité de vie. [ABSTRACT FROM AUTHOR]
