The definition of a polyacrylamide gel is just wrong - I have re-defined this several times, cant find the specific email but can re-define it, if required.
Ployacrylamide gel needs to infer as a device as it is created through some manufacturing process. For a definition of polyacrilamide the wikipedia entry is fine, this is not the same as polyacrylamide gel http://en.wikipedia.org/wiki/Polyacrylamide
definition editor is Philippe - assigning to him.
Discussed on Feb 8, 2016 call.
The definition and logic axioms of Ployacrylamide gel looks good. We don't think it is the device.
