Such an approach is possible because this coefficient is not a material property but expresses only the ability of a given charge to transfer heat. In the case of the analysed charge, this feature greatly depends on the contact conditions in adjacent sections’ layers, which may vary for ...
However, the rate of heat transfer shows a diminishing behavior with an increasing value of the Weissenberg parameter. Keywords: slip effects; mixed convection flow; cross fluid; Darcy–Forchheimer model 1. Introduction Many liquids such as detergents, printer ink, animal blood, foodstuff, paints, ...

This indicates that the addition of the blunt body reduces the boundary layer thickness and enhances the mass and heat transfer characteristics in the region. The study reveal that as the blockage ratio increases, the overall field synergy of the combustor initially increases and then decreases. ...
In general, such devices have the ability to transfer heat along a single axis. More recently, devices which can transfer heat in more directions or over an increased surface area have been termed as “vapor chambers”, but both devices share common things regarding their design and operation ...
Heartbeats at this frequency are generally known as “theta (Ѳ) waves”, with stronger Ѳ waves seeming to improve the brain's ability to learn and keep sensory information. When placed in a VR environment, the rat’s Ѳ waves became stronger.“It turns out that amazing things happen...
By loading living cells, the HUVECvegf165+-laden hydrogel was considered to be a living material with a remarkable self-renewal ability of VEGF 165, which is a splice variant of VEGFA that can be secreted extracellularly49,50,51. To verify this, we compared the releasing kinetics of VEGF...
