Uniformly distributed floor sources of buoyancy can give rise to significant spatial inhomogeneities within rooms

Flow, 2023
Displacement ventilation, where cool external air enters a room through low-level vents and warmer air leaves through high-level vents, is characterised by vertical gradients in pressure arising from the warmer indoor temperatures.

Tankyrase inhibitor XAV-939 enhances osteoblastogenesis and mineralization of human skeletal (mesenchymal) stem cells

Scientific Reports, 2020
Tankyrase is part of poly (ADP-ribose) polymerase superfamily required for numerous cellular and molecular processes. Tankyrase inhibition negatively regulates Wnt pathway.

CFD prediction and experimental visualisation of cavitation and its erosion in hydraulic valves

Flow
This article presents an experimentally validated computational fluid dynamics (CFD) model for localising and quantifying cavitation erosion in oil hydraulic valves using large eddy simulation (LES) turbulence modelling and the cavitation erosion indices

Neural prediction model for transition onset of a boundary layer in presence of two-dimensional surface defects

Flow, 2023
Predicting the laminar to turbulent transition is an important aspect of computational fluid dynamics because of its impact on skin friction. Traditional transition prediction methods such as local stability theory or the parabolized stability equation ...

lncRNA LINC00460 promoted colorectal cancer cells metastasis via miR-939-5p sponging

Cancer Management and Research, 2019
Background lncRNAs are widely involved in multiple malignancies including colorectal cancer (CRC). The expression and function of long intergenic non-protein coding RNA 460 (LINC00460) in CRC remains obscure.

Insights into the enhanced flow resistance due to coarsened riverbed sediments via large-eddy simulations

Flow
In this study, the method of large-eddy simulation (LES) is applied to investigate the impact of patches of coarsened riverbed sediments on near-bed hydrodynamics and flow resistance. Six simulations are performed with riverbed coverage ratios of coarser

Breast cancer-secreted miR-939 downregulates VE-cadherin and destroys the barrier function of endothelial monolayers.

Cancer Letters, 2017
Exosomes-secreted microRNAs play an important role in metastatic spread. During this process breast cancer cells acquire the ability to transmigrate through blood vessels by inducing changes in the endothelial barrier.

The Effect of Milling Parameters on Surface Properties of Additively Manufactured Inconel 939

, 2020
This research focuses on experimental studies on Inconel 939, which is a material used in aerospace applications where more commonly preferred Inconel 718 is not usable due to high-temperatures.

Effects of Pre-Weld Heat Treatment and Heat Input on Metallurgical and Mechanical Behaviour in HAZ of Multi-Pass Welded IN-939 Superalloy

Metals, 2020
Heat-affected zones (HAZs) of Inconel 939 (IN-939) superalloy are susceptible to cracking during welding process. Preventing cracking during the repair welding of turbine components is important.

Coalescence of microbubbles for the double-bubble-powered micromotor in viscous liquids near a confinement boundary

Flow
As a novel type of catalytic Janus micromotor (JM), a double-bubble-powered Janus micromotor has a distinct propulsion mechanism that is closely associated with the bubble coalescence in viscous liquids and corresponding flow physics. Based on high-speed
