Perhaps you should try some spelling variations:
transfer scheme » transfer systems
transformed a » transformed 1, transformer 1, transformer _
den transfer » gene transfer, heat transfer, data transfer
scheme prior » schemes prior, scheme from, schemes pro
agua el » agua e, aguas del
agua y » agua e, agua 2, agua _
y den » _ den, y de, i den
el a » e a, et a, en a

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (( agua y den transfer scheme prior ) or ( agua el a ((transformed a) OR (transformed _)) macao ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( agua y den transfer scheme prior ) OR ( agua el a ((transformed a) OR (transformed _)) macao ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( agua y den transfer scheme prior ) or ( agua el a ((transformed a) OR (transformed _)) macao ))*".
