A film cooling apparatus with a cooling hole in a component wall. The improved method for manufacturing a weathered stone panel includes preparing a base mixture comprising wood glue and plaster of paris and applying the base mixture to a substrate. In this method, the reactive p-hydroxystyrene is generated in situ via the base-catalyzed transesterification reaction between the styrene ester and the alcohol in the presence of the base catalyst. The transceivers include receive and transmit electronics that are in signal communication with the corresponding antenna. The method according to the invention, which can easily be automated, can be used to maintain monitoring of operation of the feed even during anode effects. The invention is useful for airplane raceways having a composite skin.
