A blank of sheet material for forming a polygonal container includes a bottom panel, two opposing side panels each extending from a side edge of the bottom panel, and two opposing end panels each extending from an end edge of the bottom panel. In particular, the present invention relates to new ROCK inhibitors, compositions, in particular pharmaceuticals, comprising such inhibitors, and to uses of such inhibitors in the treatment and prophylaxis of disease. The coil heater assembly has a plurality of coils. The predesigned sets of tuning constants are derived and stored in the servo motor software, typically as a result of pretesting the servo motor model by the manufacturer, for example using manual retuning. The method is suitable for recovery of chemicals and energy both in sulphate and sulphite processes and also in cooking methods based on organic solvents.
