The device in your washing machine that spins your clothes around quickly to get the water out of them? Those are centrifuges.Centrifuges are used mostly in science. In this application, centrifugal force — the force from spinning that moves things away from the center — separates liquids ...
speed. The centrifuge is designed to run on any 12 VDC source, meaning the lab can be powered by a car battery or solar panel if necessary. Readout relies on the trusty Mark I eyeball and a pH-indicating buffer that changes color depending on how much SARS-CoV-2 virus was in the ...
the changes of capillary length and interface of wetting phase and non-wetting phase fluids are considered by the new integral method, thus the average pressure and saturation derived from the proposed double integral method is more sufficient in theoretic foundation and clearer on physical meaning. ...
The overwhelming majority of TMDs in use today are linear and passive in nature, the latter meaning that they are not externally driven but that they react solely in response to the motion of the floor in which they are installed. Passive linear TMDs are well understood and have been shown ...
There are a few considerations when designing in 3D for 3D printing. Figure out what the tolerance is for your printer. The Makerbot Replicator 2 and ExtraBot 3020 E3D (made in Thailand) we have used have about a 0.3mm tolerance -- meaning you have to leave 0.3mm along your edges to...

The axial velocity allows us to derive the transport efficiency 𝜖ϵ, meaning how well the sediment will be transported within and out of the apparatus. For this purpose, the axial velocity is related to the screw pitch 𝑏screwbscrew and the differential speed Δ𝑛Δn. 𝜖=𝑢¯...
