The present invention is related to an oxidative colouring composition for keratin fibres especially human hair. The recording medium size selecting section is configured to select a size of recording media for use in forming images from image data sets of original documents. The process can also be used for biomass based production of butanol. The invention also provides a coated substrate, which substrate comprises a surface, which surface is coated with a transparent conducting film, wherein the film comprises a doped zinc oxide wherein the dopant comprises Si, and wherein the area of said surface which is coated with said film is equal to or greater than 0. 8; a tetomilast acetonitrile solvate crystal having a powder X-ray diffraction spectrum that is substantially the same as the powder X-ray diffraction spectrum shown in FIGS.
