The invention provides an amorphous form of dapagliflozin 1,2-propanediol of Formula or hydrates thereof and their process for preparation. The alteration results in a change in the bacteria’s native level of methylation of adenine in a GATC tetranucleotide which inhibits virulence of the bacteria. The impulse function can be a playback waveform de-convolved by channel data sequence. A work function of the second gate electrode is higher than a work function of the first gate electrode.
