If you don't have MS Word then you can download a free viewer but unfortunately it's Windows only, although OpenOffice.org will open some MS Word files.
I would ban the uploading of Word documents myself.
Anyway, here's the schematic in PNG format, goodness knows why the OP didn't just post it in PNG in the first place.
Would it ba acceptable to bias at half the supply voltage so you can use a single power supply?
EDIT:
Just looked at the schematic again, it doesn't look right to me. Why is the 0V of the second op-amp connected to the output of the first?
If it's to bias the AC voltage at a certain DC level, it isn't the right way of doing it, a potential divider should be used.
