A decoy for turkey hunting utilizes a detachable turkey fan which reproduces the coloration of a natural male turkey fan to enhance the perception by wild turkeys that an interloper turkey is in the territory. The composite has a discrete phase bound together with a film of the additives, such as gypsum crystals bound together by a film of substituted starch or cellulose ether. A heat sink thermally coupled to the other end of the heat pipe, in thermal contact with the heat producing component may be used. By using the carbazole derivative according to the present invention as a hole injecting material for a hole injecting layer of a light emitting element, a driving voltage can be reduced. The use of the open grid fabric as at least one of a composite lamina provides significant improvements in both the resin infusion rate and resin distribution uniformity throughout the laminate. After lights of respective colors are collected and focused, the light is diffused in a vicinity of a film.
