Lipopolysaccharide molecules released by the bacteria Vibrio fischeri when it rotates its flagella prompts its host, the Hawaiian bobtail squid, to prepare for its arrival.
A viscous dashpot destabilizes the plate when it rotates at supercritical speed by negatively damping the backward-travelling wave components of the plate eigenmodes.
The objective of the study is to evaluate how the conventional Savonius wind turbine performs when it rotates by the momentum of water current at low velocity from 0.3 m/s to 0.9 m/s in an open water channel.
After the sun heats one side, the surface cools when it rotates into shadow and emits infrared radiation.
The Evul Todai uses a heat convection turning system for the photo lens, and because there is no motor, the device doesn't produce any annoying sounds when it rotates (the turning intervals are adjustable between 4 and 22 seconds).
The cluster has the shape of an asymmetric chain, so when it rotates randomly in the fluid, probably due to Brownian motion, the shape of its projection in the microscopy images (i.e., in the x y plane, see definition in Fig. 1) keeps on changing.
