Perhaps you should try some spelling variations:
transfer schemes » transfer scheme, transfer systems
mais transfer » mass transfer, gas transfer, mit transfer
transformed a » transformed _, transformed 1, transformer 1
schemes vss » schemes das, schemes use, schemes versus
langue des » langue de, lange des, lange der
des mais » de mais, des fais, des pais
a acao » a adocao
owe a » one a, owe _
we a » web a, we _, e a

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: (( langue des mais transfer schemes vss ) OR ( vague ((we a) OR (owe a)) transformed a acao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( langue des mais transfer schemes vss ) or ( vague ((we a) OR (owe a)) transformed a acao ))~".
• Adding a wildcard symbol may retrieve word variants: (( langue des mais transfer schemes vss ) or ( vague ((we a) OR (owe a)) transformed a acao ))*.
