A polymorphic forms of the hydrochloride salt and mesylate salt of racemic -1-cyclopropyl-6-fluoro-8-methoxy-7–1,4-dihydro-4-oxo-quinoline-3-carboxylic acid, dextrorotatory R–1-cyclopropyl-6-fluoro-8-methoxy-7–1,4-dihydro-4-oxo-quinoline-3-carboxylic acid and S–1-cyclopropyl-6-fluoro-8-methoxy-7–1,4-dihydro-4-oxo-quinoline-3-carboxylic acid having formula and respectively are described. The visualization may include color, shading, or other highlighting to show resource utilization or performance metrics. These microactuators control the movement of spring-like shape-retaining interior aperture covers, which covers can be belleville springs or flat springs. The Nth relative high ability driver is vertically coupled to the first relative high ability driver through one relative low loading TSV and TSVs to act as dummy loadings. In one preferred embodiment, the additive includes: a first surface-active agent having an HLB in a range of about 5 to about 9; a second surface-active agent having an HLB in a range of about 11 to about 13; a third surface-active agent having an HLB in a range of about 14 to about 33; a coupling agent; and a coalescing solvent.
