The present invention is directed to pyrimidine compounds which are useful as therapeutic agents for the treatment of central nervous system disorders associated with phosphodiesterase 10. 005 and a second polymeric layer having an out-of-plane birefringence more negative than \u22120. The reusable portion may also contain a portion of the electrode necessary to receive electrical signals from the body of the patient. The second foam skin is laminated to a bottom of the foam core. The coupling system may be configured to couple the rotational energy generated by each of the windmills to the electric generator in a manner that permits the windmills to rotate at different speeds during operation of the electric energy generation system. The basket supporting assemblies are pivotally mounted so as to be capable of independent deployment and stowing to facilitate loading and unloading in turn.
