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.
Both modes of fire involve three essential elements: fuel, oxidizing agents (usually oxygen from the air), and a temperature high enough for the reaction to proceed (heat). In addition, the flaming mode of combustion also involves uninhibited chain reactions (collision of molecules to sustain flame continuity). In each mode all of the basic requirements must exist for the fire to start and be sustained. In most cases, flaming combustion will cease if the oxygen concentration is
