Filing a petition for a writ of certiorari to the U.S. Supreme Court does not automatically stay the mandate. Nonetheless, certiorari petitions are a common basis for asking an appellate court to issue a stay. Rule 41 expressly contemplates such motions.
The Fire Triangle. Three things are required in proper combination before ignition and combustion can take place---Heat, Oxygen and Fuel. There must be Fuel to burn. There must be Air to supply oxygen. There must be Heat (ignition temperature) to start and continue the combustion process.
Heat: In order to start a fire, the fuel and oxygen reacting with each other must exceed a threshold called the flash point. The flash point is the temperature at which the chemical reaction can combust, producing a flame. Different chemicals have different flash points, some relatively high, and some incredibly low.
