Perhaps you should try some spelling variations:
presentada » presentan, presentar, presenteda, presenteada
presentado » presentan, presentar, presentacion, presentedo, presenteado
presentean » presentan, presenten, presenteen, presenteean
presented » presente, presentan, presenteed
presenta » presente, presentea
presentarse » presenterse, presentearse
present » presente

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