Perhaps you should try some spelling variations:
railways transport » railway transport, rail transport
biomass transport » mass transport, mass transports, biogenesis transport
airways transport » waterways transport, pathways transport, waterway transport
biomass transfer » mass transfer, diseases transfer, process transfer
bioheat transfer » heat transfer, light transfer, direct transfer

Try widening your search to All Fields.

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: %((((biomass transfer) OR (bioheat transfer))) OR (((biomass transport) OR (((airways transport) OR (railways transport))))))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((((biomass transfer) or (bioheat transfer))) or (((biomass transport) or (((airways transport) OR (railways transport))))))%22".
• Adding a wildcard symbol may retrieve word variants: %((((biomass transfer) or (bioheat transfer))) or (((biomass transport) or (((airways transport) OR (railways transport))))))%22*.
