A set of ink cartridges is configured to mount in a cartridge mounting portion of a recording apparatus in an insertion direction. The reticulated plug may be used in combination with various types of conventional injection connectors to allow swapping of an insulative permanent plug for an injection plug after a dielectric enhancement fluid has been introduced into the interior of a cable using the reticulated plug, wherein the cable is energized during the swapping operation. The tubular enclosure has a plurality of tapered protrusions extending from the light-receiving portion toward the LEDs. A high-k dielectric is formed between the first metal line and the second metal line in the region where the interlevel dielectric was removed such that a capacitor is formed by the first metal line, the second metal line and the high-k dielectric. Alternatively, an insert ring can be received by the nut and the insert ring can include teeth. The organic template is then removed, thereby forming a metal oxide coating having a plurality of macromolecular-sized apertures formed therein.
