Talvez debería tentar con algunhas variantes ortográficas:
irrigation requirements » irrigation equipment, nutrition requirements
requirements using » requirements modeling
using divisions » using division, using decision, using vision
array profiling » array processing, microarray profiling
array imaging » arrays imaging, airway imaging, ray imaging
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 using divisions ((((array imaging) OR (arrays ang))) OR (array profiling))~.
• Adding a wildcard symbol may retrieve word variants: irrigation requirements using divisions ((((array imaging) or (arrays ang))) or (array profiling))*.
