Talvez debería tentar con algunhas variantes ortográficas:
irrigation requirements » irrigation equipment, nutrition requirements
requirements under » requirements using, requirements based, requirements case
under divisions » gender divisions, new divisions, upper division
array imaging » arrays imaging, airway imaging, ray imaging
array string » array strong, arrays strings, array sharing
arrays ang » arrays a

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: irrigation requirements under divisions ((((array string) OR (arrays ang))) OR (array imaging))~.
• Adding a wildcard symbol may retrieve word variants: irrigation requirements under divisions ((((array string) or (arrays ang))) or (array imaging))*.
