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.
Stages of fire. 1  Ignition: Fuel, oxygen and heat join together in a sustained chemical reaction. At this stage, a fire extinguisher can control the fire. 2  Growth: With the initial flame as a heat source, additional fuel ignites. Convection and radiation ignite more surfaces.
