Various embodiments provide a method and apparatus for providing redundant data access. An air mover is provided for causing air to flow into the air ionizer through the air inlet and out of the air ionizer through the air outlet. Methods for producing a maize plant containing in its genetic material one or more traits introgressed into PH1C4F through backcross conversion andor transformation, and to the maize seed, plant and plant part produced thereby. Alloying the substrate with monatomic hydrogen may also be done after deposition of a metal layer, or at other process steps as desired. The cutting blade also includes a reflective surface having a generally parabolic shape formed within the body of the cutting blade which is positioned to reflect laser radiation entering the cutting blade through the refracting means towards the curing edge of the blade.
