Whiteout, white-out, or milky weather is a weather condition in which the contours and landmarks in a snow-covered zone become almost indistinguishable. It could be also applied when visibility and contours are greatly reduced by sand .
Differential heat treatment (also called selective heat treatment or local heat treatment) is a technique used during heat treating of steel to harden or soften certain areas of an object, creating a difference in hardness between these areas.
Tempering is a heat treatment technique applied to ferrous alloys, such as steel or cast iron, to achieve greater toughness by decreasing the hardness of the alloy. The reduction in hardness is usually accompanied by an increase in ductility, thereby decreasing the brittleness of the metal.
Greyout. Simulated stages of a greyout. A greyout is a transient loss of vision characterized by a perceived dimming of light and color, sometimes accompanied by a loss of peripheral vision. [1] It is a precursor to fainting or a blackout and is caused by hypoxia (low brain oxygen level), often due to a loss of blood pressure .
March 14, 2024 at 8:04 PM. CHICAGO (AP) — The Clippers and Bulls were missing key players Thursday, with Los Angeles' James Harden out with a strained left shoulder and Chicago's Coby White...
Induction hardening. Induction hardening is a type of surface hardening in which a metal part is induction-heated and then quenched. The quenched metal undergoes a martensitic transformation, increasing the hardness and brittleness of the part. Induction hardening is used to selectively harden areas of a part or assembly without affecting the ...
The White Out is a tradition at the Pennsylvania State University during select Nittany Lions home football games, where all spectators come dressed in white. It has been described as "the best atmosphere in college football." [1] It is also among the most expensive regular season games of college football, with ticket prices ranging upwards of ...
Whitey (drugs) A whitey or white-out (sometimes "green-out" or "greening") is a drug slang term for when a recreational drug user, as a direct or indirect result of drug use (usually cannabis ), begins to feel faint and vomits. [1] The term derives from the "whiteout" weather condition where a snowstorm causes loss of vision, and refers to the ...
Cold hardening is a process in which a plant undergoes physiological changes to avoid, or mitigate cellular injuries caused by sub-zero temperatures. [1] Non-acclimatized individuals can survive −5 °C, while an acclimatized individual in the same species can survive −30 °C.
Vulcanization (British English: Vulcanisation) is a range of processes for hardening rubbers. [1] The term originally referred exclusively to the treatment of natural rubber with sulfur, which remains the most common practice. It has also grown to include the hardening of other (synthetic) rubbers via various means.
