Talvez debería tentar con algunhas variantes ortográficas:
communication control » communication concepts, communication culture, communication channel
course dimensions » core dimensions, four dimensions, course divisions
control course » control coupled, control case, control costs
scale spaces » scale space, sample spaces, tuple spaces
safe spaces » state spaces, shape spaces, life spaces
use spaces » tuple spaces, phase spaces, gauge spaces

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: communication control course dimensions ((((safe spaces) OR (scale spaces))) or (use spaces))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication control course dimensions ((((safe spaces) OR (scale spaces))) OR (use spaces)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "communication control course dimensions ((((safe spaces) OR (scale spaces))) or (use spaces))".
• Adding a wildcard symbol may retrieve word variants: communication control course dimensions ((((safe spaces) OR (scale spaces))) or (use spaces))*.
