An array of sheet materials includes a first sheet, a second sheet, and an interior sheet located between the first sheet and the second sheet, each sheet having a centrally located medial primary fold formed therein and a secondary off-fold transverse thereto, the medial fold and the transverse off-fold defining four panels in each sheet. The device requests the media item from a server in response to the user input and, in response to the request, receives, from the server, the one or more media files and information identifying at least the portion of the audio track. A second decoded bit and a second set of decoding parameters are generated using the first set of decoding parameters. In the most preferred embodiment, liquid-permeable cover sheets are adhered to the upper and lower major surfaces of the bacterial-containing geotextile article to prevent a powdered or granular material from escaping from the geotextile during transportation and installation. The size of the half-tone exposure units is randomly selected. Vectors and transgenic cells that include a nucleic acid sequence encoding a DGAT2 polypeptide are also described.
