Perhaps you should try some spelling variations:
presented » presente, present, presentan
presenteda » presentea, presenta, presentana, presentera, presentida, presentedans
presentecion » presentacion, presentacione, apresentacion
presentada » presentado, presentan, presentar, presenteda
presentaba » presentaban, presentara, presentadas, presenteba
presenta » presente

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

• Performing a fuzzy search may retrieve terms with similar spellings: (presented or (((presentecion or (presenteda OR presentada)) or presentaba) or presenta))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (presented OR (((presentecion OR (presenteda OR presentada)) OR presentaba) OR presenta))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(presented or (((presentecion or (presenteda OR presentada)) or presentaba) or presenta))*".
