Escherichia Coli to Swim Upstream Jane Hill, Ozge Kalkanci,
... An E. coli bacterium has two to six flagella, which, when rotating counterclockwise, form a bundle that propels the cell forward (a ‘‘run’’). During a run, the flagellar bundle rotation is counterbalanced by cell body rotation in the opposite direction [1]. The propulsive force of the flagellar bund ...

... For horizontal flow through a capillary tube of length L and radius R, the time t it takes to fill a certain volume V is measured. The flow pressure p , is fixed during the process, by maintaining a constant fluid level at a certain elevation above the capillary tube. The accuracy in these meas ...

... Force is a vector and we can always decompose a vector into its three component. The component perpendicular to the surface is the pressure while the two components parallel to the surface are stresses. Thus the wind applies a stress on the ocean surface (and some pressure when waves are present) wh ...
