Stress granule formation as a marker of cellular toxicity in lung organoids [PDF]

Organoid, 2022
Cells regulate protein synthesis under stressful circumstances by forming cytoplasmic RNA granules, termed stress granules (SGs). SGs are membrane-less organelles that function as a protective mechanism in response to stress. They function through liquid-

Impact of Operating Conditions on the Performance of a Flat Membrane Humidifier with Two-Way Serpentine Channels in Building Applications [PDF]

Iranian Journal of Chemistry & Chemical Engineering
In common flat membrane humidifiers, the flow channels have a simple parallel arrangement on two dry and wet sides. The implementation of serpentine flow improves the residence time of gases within the channels, creates vortices in the bends of the ...

[P1.036] Modeling the Permeability of Gases in Humidified Ionomeric Membranes

Procedia Engineering, 2012
In this work, we modelled with a CFD technique, based on a finite-volume algorithm, the permeability of gases at different relative humidities in short-side chain and long-side-chain ionomer membranes suitable for fuel cells, namely Aquivion and Nafion 117.
