In the lecture notes

http://webraft.its.unimelb.edu.au/64...n/lecture3.pdf [Broken]

on the very last page, should the second realisation relation have -(dU/dp) instead of the + (dU/dp)?

You need to fix the link. I get a 404 error.

I fixed up the error I think it is on this page and have edited my OP accordingly.

I have derived it again and realised that I used the wrong dQ. It should have been dQ=dU-dW whereas I used dQ=dU+dW.

First Law applications can be an enormous pain in the ass - some people sometimes define dQ and dW as either done ON the system or done BY the system quite arbitrarily - which of course changes their sign.
