Perhaps you should try some spelling variations:
heart transfer » heat transfer, net transfer, far transfer
transfer costs » transport costs, transfer amounts
costs across » scores across, risks across
transfer bei » transfer beim, transfers bei, transfer der
bei adam » i adam, bei aal
a heart » _ heart, 3 heart, a health
gene 3 » gene _, gene 1, gene 6
gene m » gene _
luis a » luis f, luis c

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: (( luis ((gene 3) OR (gene m)) transfer costs across ) OR ( luis a heart transfer bei adam ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis ((gene 3) OR (gene m)) transfer costs across ) or ( luis a heart transfer bei adam ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis ((gene 3) OR (gene m)) transfer costs across ) or ( luis a heart transfer bei adam ))*.
