Thanks @zhengj2007. I checked this locally by adding the axiom

continuant DisjointWith 'part of' some occurrent

then ran the reasoner. #1050 was fixed but I found another similar problem with OBI:0002053 'microarray assay measuring binding of a B cell epitope:antibody complex':

'assay measuring qualitiative binding of a B cell epitope:antibody complex'
and ('has part' some microarray)

I think it should be 'has part' some 'microarray assay'. I'll update this PR to fix that problem too.
