Shear Behavior of Green Concrete Beams Reinforced with Basalt FRP Bars and Stirrups.
منشور في 2020"…It has been found that the green concrete provides high compressive strength compared to the normal concrete with the same workability properties, which increases the shear resistance by the concrete. Finally, minimizing spacing of the stirrups is not preventing occurrence of the crack, however using minimum spacing helps in decreasing the crack width.…"

Development and in Vitro Testing of a Nitric Oxide Nanoparticle Carrier for Acute Lung Injury
منشور في 2020"…Fluid filled lungs need to be mechanically ventilated for airway reopening.Ventilation might further damage delicate lung tissue and lead to edema,a phenomenon known as ventilator-induced lung injury VILI is a result of propagation of small air bubbles in gas exchange sites, injuring epithelial cells due to shear stress. Potential rescue of epithelial cells (EPCs) under injurious stresses is possible by altering their mechanical properties and hence deformation amount under stress (decreased stiffness, decreased deformation). …"
