Individual packages for absorbent article that are flushable and water dispersible are disclosed. Plant genes encoding senescence-induced deoxyhypusine synthase and senescence-induced elF-5A are identified and the nucleotide sequences of each, alone and in combination are used to modify senescence in transgenic plants. An emitter window is masked directly over the polysilicon trench fill. The first slurry comprises at least an organic polymeric abrasive.
