The invention relates to an aerially transportable tank for storing a composition for discharging in flight, the tank including a neck terminated by a composition discharge opening, and having a wall extending the neck that is sufficiently deformable to be received in part or in full within the neck. A damaged functional group generated in a surface of the low dielectric insulating film by a processing is substituted with a hydrophobic functional group. An exciter is also included, and is adapted to impart vibrational action to the supported cards. The panty includes an absorbent barrier composite positioned in the crotch area and extending into the body of the disposable panty front and back and over the leg elastics to trap pad leakage inside the pant and prevent liquid strike through onto outer clothing and bed linen. During a connected components graph labeling process, when a merge is encountered, the data structure comprising labels and associated equivalency data swaps the equivalency data of the two vertices whose different labels produced the merge condition.
