Journal ArticleDOI
Dynamic analysis of the aortic valve using a finite element model
TL;DR: The complex interplay of the geometry of the valve system can be effectively analyzed using a sophisticated dynamic finite element model and results not previously brought out by the earlier static analysis shed new light on the root/valve interaction.
Journal ArticleDOI
Further insights into normal aortic valve function: role of a compliant aortic root on leaflet opening and valve orifice area
TL;DR: The compliance contributes much to the ability of the normal aortic valve to increase its effective valve orifice in response to physiologic demands of exercise, and this effect is strikingly absent in stiff roots.
Journal ArticleDOI
Transient Finite Element Analysis of Tire Dynamic Behavior
TL;DR: In this article, the effects of camber angle and grooved tread on tire cornering behavior are discussed, and ABAQUS/Explicit, a general nonlinear finite element (FE) code, was used for these simulations.
Journal ArticleDOI
An open label randomized clinical trial of Indomethacin for mild and moderate hospitalised Covid-19 patients

TL;DR: Indomethacin, a non-steroidal anti-inflammatory drug (NSAID), has been presented as a broad-spectrum antiviral agent in this paper , which evaluated the efficacy and safety of this drug in RT-PCR-positive coronavirus disease 2019 patients.
Journal ArticleDOI
Aortic valve dynamics using a fluid structure interaction model--The physiology of opening and closing.
TL;DR: The proposed boundary condition delivers all the insights offered by the pressure and flow boundary conditions, along with providing an unbiased framework for the analysis of different valves and hence, more suitable for comparative analysis.
