Talvez debería tentar con algunhas variantes ortográficas:
information instruments » informational instruments, information instrumental, deformation instrument
instruments intra » instruments india, instruments internal, instruments data
intra extension » integral extension, central extension, binary extension
array imaging » arrays imaging, airway imaging, artery imaging
array paving » array planning, array probing, array sharing

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: information instruments intra extension ((array paving) OR (((array imaging) OR (ray imaging))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "information instruments intra extension ((array paving) or (((array imaging) OR (ray imaging))))~".
• Adding a wildcard symbol may retrieve word variants: information instruments intra extension ((array paving) or (((array imaging) OR (ray imaging))))*.
