Perhaps you should try some spelling variations:
networks synthesis » network synthesis, networks systems
health incidence » health incident, health science, health evidence
death incidence » growth incidence, dengue incidence, graphs incidence
nets synthesis » net synthesis, dots synthesis, its synthesis
guide network » side network, wide network, inside network

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 incidence) OR (death incidence)) ((networks synthesis) OR (nets synthesis)) report ) OR ( earth ((guide network) OR (guided network)) synthesis report )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((health incidence) or (death incidence)) ((networks synthesis) or (nets synthesis)) report ) or ( earth ((guide network) OR (guided network)) synthesis report ))".
• Adding a wildcard symbol may retrieve word variants: (( ((health incidence) or (death incidence)) ((networks synthesis) or (nets synthesis)) report ) or ( earth ((guide network) OR (guided network)) synthesis report ))*.
