How can I define "Heat Transfer in Fluids" for water that flows through an air domain and reaches a Wetted Wall in COMSOL Multiphysics for a 2D model?

Hi all, I hope everyone is doing well and is in good health. In the simulation it is needed to change the phase of water that flows through an air domain. So I used Laminar Flow and Level Set...

Have you ever seen that 40S and 60S of ribosome subunit peaks disappear from polysome fractionation?

I am doing polysome fractionation for stress conditions for mammalian cell. it seems that peaks of 40S and 60S disappear during stress condition compared to control. I am wondering whether all...

What is the effect of immidazole on activity and stability of enzyme?

When enzymes were eluted with high concentration immidazole, some of them lost their activity in 2 days. I want to know how immidazole affect enzyme or other protein. I can't find article about that.
