Perhaps you should try some spelling variations:
transfer schemes » transfer scheme, transfer systems
den transfer » gene transfer, heat transfer, data transfer
schemes pro » schemes prior, schemes part, schemes2 pre
aguas de » aguas del, aguas do, vagues de
de den » die den, der den, de don
del a » del av, del i, del 2
del 1 » del i, del 2, del 3

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 de den transfer schemes pro ) OR ( aguas ((del a) OR (del 1)) transformed _ macao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( aguas de den transfer schemes pro ) or ( aguas ((del a) OR (del 1)) transformed _ macao ))~".
• Adding a wildcard symbol may retrieve word variants: (( aguas de den transfer schemes pro ) or ( aguas ((del a) OR (del 1)) transformed _ macao ))*.
