Talvez debería tentar con algunhas variantes ortográficas:
communication motivation » communication foundation, communication satisfaction, communication implications
motivation set » motivation self, motivation based, motivation case
spaces » dspaces
dspaces » ddspaces
dddspaces » ddddspaces
space* » dspace*

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

• Performing a fuzzy search may retrieve terms with similar spellings: communication motivation set (((spaces OR dspaces) or dspaces) or dddspaces) euclidean space~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication motivation set (((spaces OR dspaces) OR dspaces) OR dddspaces) euclidean space*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "communication motivation set (((spaces OR dspaces) or dspaces) or dddspaces) euclidean space*".
