The present invention provides compounds, compositions and methods for the selective inhibition of cathepsin S. The method comprises mixing of aniline and a lignosulfonate in the presence of a transition metal salt. This construction widens a servo band width, improves positioning accuracy, and reduces positioning errors of a magnetic disk apparatus, so that recording density is improved and storage capacity is increased. The interactive chart can be shared by, for example, embedding the interactive chart in an external electronic document, such as a. Through coupling relationship between the first and second lift cords and the lift cord retracting and releasing control means the slat assembly already rolled up or extended at a selected elevation can be altered to another elevation.
