Perhaps you should try some spelling variations:
presenteds » presentes, presentees, presentedans, presentas, presents
presentaron » presentacion, presentation, presentan
presentadas » presentas, presentans, presentars
presentada » presenta, presentan, presentar
presented » presente, presenta, present
presentado » presenta, presentan, presentar

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: (presentadas OR ((presenteds OR (presentaron OR (presentada OR presented))) OR presentado))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(presentadas or ((presenteds or (presentaron or (presentada OR presented))) or presentado))~".
• Adding a wildcard symbol may retrieve word variants: (presentadas or ((presenteds or (presentaron or (presentada OR presented))) or presentado))*.
