Perhaps you should try some spelling variations:
communicative functions » communication foundations
basic dimensions » based dimension, pacific dimensions, design dimensions
functions basic » functions based, foundations basic
array imaging » arrays imaging, airway imaging, ray imaging
array ang » arrays ang, array along, array range
arrays a » arrays _

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: communicative functions basic dimensions ((((array ang) OR (array imaging))) OR (arrays a))~.
• Adding a wildcard symbol may retrieve word variants: communicative functions basic dimensions ((((array ang) or (array imaging))) or (arrays a))*.
