Perhaps you should try some spelling variations:
transfer schemes » transfer scheme, transfer systems
18 transformed » _ transformed, a transformed, vi transformed
transformed 1 » transformed _, transformer 1, transformed a
den transfer » gene transfer, heat transfer, data transfer
schemes fair » schemes fare, schemes after, schemes prior
aguas dem » aguas de, aguas del, aus dem
1 macro » _ macro, a macro, 2 macro
agua 2 » agua _, agua y
dem 18 » dem 19

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: (( ((agua e) OR (agua 2)) den transfer schemes fair ) OR ( aguas dem 18 transformed 1 macro ))~.
• Adding a wildcard symbol may retrieve word variants: (( ((agua e) or (agua 2)) den transfer schemes fair ) or ( aguas dem 18 transformed 1 macro ))*.
