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