A method is provided for producing an ester-substituted phenol product stream from an ester-substituted diaryl carbonate manufacturing waste stream. An upper surface of the semiconductor substrate has a first trench and a second trench. Each extended leg has a pair of wheels that when used in conjunction with the handle allows the entire apparatus to serve as an infant stroller in a manner similar to a wheelbarrow. The second transformer includes a primary coil and a secondary coil. Additionally, multiple conditional formatting rules may be evaluated to TRUE for the same cell contained in a user interface and multiple formats applied to that cell. The switch control circuit turns ON the analog switch group after it has detected that all analog switches of the analog switch group have been turned OFF, and turns ON the analog switch group B after it has detected that all analog switches of the analog switch group have been turned OFF.
