Perhaps you should try some spelling variations:
influence networks » inference networks, inference network, reference networks
networks synthesis » networks systems, nets synthesis
network synthesis » network systems
science networks » science network, sequence networks, science works
sciences network » services network
health influence » heart influence, death influence, earth influence
health impedance » health importance, health temperance, head impedance

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: (((( health ((science networks) OR (sciences network)) synthesis report ) OR ( health influence networks synthesis report ))) OR ( health impedance network synthesis report )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( health ((science networks) OR (sciences network)) synthesis report ) or ( health influence networks synthesis report ))) or ( health impedance network synthesis report ))".
• Adding a wildcard symbol may retrieve word variants: (((( health ((science networks) OR (sciences network)) synthesis report ) or ( health influence networks synthesis report ))) or ( health impedance network synthesis report ))*.
