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.
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 .
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 ...
Membrane dryer refers to a dehumidification membrane that removes water vapor from compressed air. Membrane dryers operate on the principle of migration. The compressed air to be dried is passed over a membrane that has a high affinity for water vapor. The water vapor builds on the membrane and migrates through to the opposite or low pressure ...

Contact freeze dryers use contact (conduction) of the food with the heating element to supply the sublimation energy. This type of freeze dryer is a basic model that is simple to set up for sample analysis. One of the major ways contact freeze dryers heat is with shelf-like platforms contacting the samples.

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 ...
