Talvez debería tentar con algunhas variantes ortográficas:
irrigation requirements » irrigation equipment, nutrition requirements
requirements c.w » requirements can, requirements ch, requirements case
c.w divisions » new divisions, cell divisions, _ divisions
array imaging » arrays imaging, airway imaging, ray imaging
array along » arrays long, array arcing, array paving
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 c.w divisions ((((array along) OR (arrays ang))) OR (array imaging))~.
• Adding a wildcard symbol may retrieve word variants: irrigation requirements c.w divisions ((((array along) or (arrays ang))) or (array imaging))*.
