A substrate assembly for a gas discharge panel, comprising a dielectric layer and a protective layer of MgO being formed in this order on a substrate having electrodes,wherein the dielectric layer is a laminate of an organic dielectric layer and an inorganic dielectric layer in this order from a side of the substrate. The dispenser propels precise volumes of bioactive agent toward the skin, where they exert a local or topical effect, or move through the skin for transdermal systemic delivery. The pivoting member is attached to the ripping-open-section and extends in the same general direction as the central axis. In another embodiment, the biomedia apparatus is utilized outside a power plant to minimize spat that is drawn into the plant through water intake valves. The pillar layer is planarized to form pillars embedded in said dielectric layer. A common-mode component of the differential output signal is decoupled from the differential output signal using a common-mode voltage sense.
