Alternating-current thin-film electroluminescent (ACTFEL) devices are used in the
formation of pixels in flat panel displays. ACTFEL flat panel displays have many
advantages over other flat panel technologies. Specifically, ACTFEL panels are emissive
displays, they have high brightness, wide viewing angles, and rugged construction.

(Rhyacionia spp.) occurs on ponderosa pine (Pinus ponderosa)

individual species relative abundances showed west-to-east
trends.
