Minimizing the operating clearance between rotating bladed-disks and stationary surrounding casings is a primary concern in the design of modern turbomachines since it may advantageously affect their energy efficiency.
The aerodynamic damping of oscillating plates, evaluated in terms of a quality Q-factor from a frequency response resonance curve, was found to vary linearly with the absolute pressure in stationary surrounding air and with the air flow velocity in moving air.
One of the three porpoises, Freja, was trained to approach a stationary target surrounded by a star-shaped array of 48 hydrophones in two configurations (Video 2).
Larvae were placed in a small Petri dish containing 3% methylcellulose and mounted on a stationary platform surrounded by a rotating drum of 8 cm in diameter.
Video shows AAV-NT-3 and AAV-BDNF treated rats at 6 weeks post-Tx, crossing a stationary platform surrounded by a Plexiglas enclosure.
If your car is going to be stationary, you can surround your car with zombies.
The magnet turns within a movable metal cup made of a light nonmagnetic metal that is attached to the shaft carrying the indicating pointer; the magnetic circuit is completed by a circular stationary field plate surrounding the movable cup.
Measurements have been made of overall rates of mass transfer from the surfaces of a rotating cylinder and a surrounding stationary concentric tube to an axial stream of water in laminar + vortex flow in the long annular channel between them.
The Plains Aborigines mainly lived in stationary village sites surrounded by defensive walls of bamboo.
The video ends with Knowles shooting a gun while perched upon a stationary motorcycle and surrounded by images from the start of the video.
