Review: Protein secondary prediction continues to rise

A chain saw is movably mounted on a frame for enabling the chain saw blade to move in a substantially straight-line path relative to the frame. The frame includes a bed for supporting a length of wood within the straight-line path of the saw blade. The saw blade is biased toward one side of the length of wood and a foot treadle is connected to the saw for overcoming the bias and moving the saw blade along the straight-line path to the other side of the length of wood.
