The invention relates to a blade for a turbine, comprising at least one channel which is delimited by walls. In particular embodiments, the formulations described herein include suspension formulations of nanoparticulate genistein. The beam vertically scans the two edges. The inner ring includes an internal surface with inner dogs for contacting a hub. The logic circuit may control the leakage reduction circuit so as to reduce leakage through a column select device that is not selected.
