A process for making monomenthyl esters of dicarboxylic acids is disclosed. Further, a heating device may have the heating roller, a fixing device may have the heating roller and the heating device, and an image forming apparatus may have the heating roller, the heating device and the fixing device. Control wires which connect the blade via the crane boom to a winch arrangement are used for keeping the blade orientation substantially horizontal in addition to at least one bearing wire for bearing the blade weight. Knowledge landscape visualization techniques contribute to better human decision-making insights through facilitation of spatial operations such as navigation and zoom operations.
