transfer 4 » transfer _, transfer 3, transfer a
aguas do » aguas de, aguas del
guias de » guia de, guide de, aguas de

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: (( aguas do dots ((transport safer) OR (transport safety)) a ) OR ( guias de mass transfer 4 co ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( aguas do dots ((transport safer) OR (transport safety)) a ) or ( guias de mass transfer 4 co ))~".
• Adding a wildcard symbol may retrieve word variants: (( aguas do dots ((transport safer) OR (transport safety)) a ) or ( guias de mass transfer 4 co ))*.
