Perhaps you should try some spelling variations:
transfer schemes » transfer scheme, transfer systems
transformed 1 » transformed _, transformer 1, transformed a
den transfer » gene transfer, heat transfer, data transfer
schemes vss » schemes das, schemes use, schemes versus
code den » code de, code des, code der
du code » du cote, du cadre, der code
de have » we have, de haute, de haber
do have » who have, how have
acao » cacao, macao, cao

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: (( du code den transfer schemes vss ) OR ( langue ((de have) OR (do have)) transformed 1 acao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( du code den transfer schemes vss ) or ( langue ((de have) OR (do have)) transformed 1 acao ))~".
• Adding a wildcard symbol may retrieve word variants: (( du code den transfer schemes vss ) or ( langue ((de have) OR (do have)) transformed 1 acao ))*.
