When chilled by dry ice, liquid carbon dioxide or liquid nitrogen, the thermoplastics can be finely ground to powders suitable for electrostatic spraying and other powder processes. [1] Cryogenic grinding of plant and animal tissue is a technique used by microbiologists .
The floating ice shelf is in the left foreground, and the grounding line is visible as an abrupt change in surface slope due to flexure caused by the buoyancy force where the ice reaches flotation. An ice shelf is a large platform of glacial ice floating on the ocean, fed by one or multiple tributary glaciers.
A hair dryer (the handheld type also referred to as a blow dryer) is an electromechanical device that blows ambient air in hot or warm settings for styling or drying hair. [ 1 ] [ 2 ] Hair dryers enable better control over the shape and style of hair, by accelerating and controlling the formation of temporary hydrogen bonds within each strand.
Provide a source of ground fault current during line-to-ground faults. Permit the connection of phase-to-neutral loads when desired. [2] Earthing transformer with a zig-zag. Grounding transformers most commonly incorporate a single winding transformer with a zigzag winding configuration, but may also be created with a (rare case) delta-wye ...

Appliances such as hair dryers and space heaters also use fans. They move air in air-conditioning systems and in automotive engines. Fans used for comfort inside a room create a wind chill by increasing the heat transfer coefficient but do not lower temperatures directly. Fans used to cool electrical equipment or in engines or other machines ...

Other labels refer to the ice tongue's grounding line, and northern and southern shear zones where it's in direct contact with the ice shelf. [ 29 ] The Thwaites Glacier Tongue, or Western Glacier Tongue ( 75°0′S 106°50′W / 75.000°S 106.833°W / -75.000; -106.833 ) was a narrow, floating part of the glacier, located about 30 ...
