This invention discloses 1-hydroxy-2-methylene-19-nor-homopregnacalciferol and pharmaceutical uses therefor. The apparatus further includes a test fluid container in fluid communication with the fluid inlet, and a collection container in fluid communication with the fluid outlet. One application of the present invention is in enabling autostereoscopic viewing of a display that is not otherwise configured to display 3D images. For each successive pair of complex events, including a first and a second complex event, a line is drawn on the map between their locations. By varying the rate of slurry deposition, starting out with a low rate of slurry flow that is increased as the polishing process proceeds, the invention obtains good planarity for copper surfaces while saving on the amount of slurry that is being used for the copper surface polishing process.
