A separator system operable to use centrifugation to fractionate a multiple component material, such as a suspension including blood, comprises a buoy. The improved ditch liner system includes a first liner section and a second liner section. The air, then, impinges on a plurality of vanes wherein the momentum of the air is altered, thus providing the force needed to drive the wind turbine. In an embodiment, the invention begins with a sample of points from an n-dimensional data set and a corresponding set of m-dimensional points. The first and second opposing walls have a varying thickness. According to the findings in present invention, a method for determining the cellular senescent condition in a cell or tissue sample by evaluating the expression level of cofilin is provided.
