Two novel cytochrome P450 genes are isolated from sorghum, each gene encoding a protein having pentadecatrienyl resorcinol hydroxylase activity. The collector pipes 43 optimize the purge of gases coming from the disengager vessel 49, reducing the time the hydrocarbons remain inside the disengager vessel 49, thus preventing overcracking and subsequent coke formation. Spikes of this material can be made as direct andor alternative replacements for existing metal spikes or as unique integrated devices. The shaft has recessed and non-recessed portions. A housing contains the direct current motor and has plural mounting tabs. The dental prosthesis, such as a crown or short-span bridge, is a prefabricated composite shell that is modified by the addition of composite material and cured on-site to form a custom-modified device.
