The present disclosure provides methods and systems for purifying liquids. Energy expended compressing the natural gas and air are recovered. A shaft extends through an opening of the shank. Significant increases in cell death in AT-sDNA transfected cells compared to non AT-rich sDNA treated cells were observed in both cell lines. This invention overcomes these deficiencies by providing wiring devices that have locating openings for engaging alignment pins located on a plate that is subsequently attached to a box. The lumen is sized to slidably receive a portion of the first elongate member.
