This work presents a numerical approach in order to predict the influence of implant material stiffness in a femoral component design when submitted in compression. The implant success depends on the transferred load to the neighboring bone. The finite element method can be used to analysis the stress and strain distribution in the femoral component allowing to improve the implant selection. Fo...

Mariliasuchus amarali Carvalho & Bertini, 1999 was a terrestrial quadruped crocodyliform from the Late Cretaceous of Bauru Group, Brazil. In this paper we present first study bone histology species. Moderate growth rate, interspersed by marks, observed in thin sections rib and appendicular bones; patterns M. amaralis appear similar to those Triassic archosauriforms. The cross-sections indic...

introduction: environmental pollution with heavy metals such as mercury is a major health problem. growing studies on the field have shown the deleterious effects of mercury on human and nonhuman nervous system, especially in infants, however the effects of prenatal exposure to mercuricchloride on cortical development are not yet well understood. the aim of this study was to investigate the eff...

Bubble columns are gas- liquid contactors that are widely used in chemical and bio- chemical industries. High mixing that result in high heat and mass transfer rates are amongst their advantages. Heat transfer in a bubble column having a bundle of heaters investigated and the variation of heat transfer coefficient with variation in heaters pitch to diameter ratios in a bundle of heaters reporte...

this paper presents a three-dimensional numerical investigation carried out in turbulent forced convection in a tube with helical ribs. enhancement of heat transfer using helically corrugated tubes has beenstudied experimentally by many researchers but there exist a few published numerical analyses results. the paper also introduces the results of heat transfer and friction factor data for inco...

Background: Pulmonary thromboembolism can be easily diagnosed with computed tomography (CT) and pulmonary angiography (CTPA). However, diagnosis is difficult since a contrast agent cannot used. Several criteria are recommended for the of embolism (PE) non-enhanced CT. Objectives: The aim this study to investigate value increase in artery diameter (PA-D) ratio / ascending aorta (Ao-D) (PA-D/Ao-D...
