Listing 27 . The class named MusicComposer09.
/*File MusicComposer09.java Copyright 2014, R.G.BaldwinRevised 08/27/14 This is a driver class for playing piano melodies. It works inconjunction with the following classes: AudioSignalGenerator02AudioPlayOrFile01 AudioFormatParameters01PlayerPiano01 The melody to be played is defined in one and optionally two text files. Therequired text file defines the notes and the duration of those notes on the treble clef. The optional text file defines the notes and the durations ofthose notes on the bass clef. Those text files must exist in a subfolder named Music.The melody can be played immediately or can be saved in an audio file of type AU for playback later.

what about nanotechnology for water purification
RAW Reply
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct
