Improved PMOS and NMOS transistor designs for sensing circuitry use in advanced nanometer flash memory devices are disclosed. A number of conditions are examined, and if it is found that one or more of these conditions matches a corresponding predetermined condition, the spark timing of the engine is retarded. The member has two legs that are deflectable relative to each other. A back retainer retains the rubber plugs in the wire insertion tube. A body of the end cap is intermediate to the first and second surfaces of the end cap and has a CTE intermediate of the first and second CTE. A portion of the propane and butane is removed from the higher molecular weight hydrocarbons and reacted with the mixture of alkyl bromides and hydrobromic acid over the synthetic crystalline alumino-silicate catalyst to form C5+ hydrocarbons.
