Perhaps you should try some spelling variations:
networks synthesis » network synthesis, networks systems, nets synthesis
health incidence » health incident, health science, health evidence
death incidence » growth incidence, dengue incidence
grid networks » hybrid networks, world networks, bridged networks
grid network » hybrid network, world 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 report ) OR ( health ((grid network) OR (grid networks)) synthesis report )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((health incidence) or (death incidence)) networks synthesis report ) or ( health ((grid network) OR (grid networks)) synthesis report ))".
• Adding a wildcard symbol may retrieve word variants: (( ((health incidence) or (death incidence)) networks synthesis report ) or ( health ((grid network) OR (grid networks)) synthesis report ))*.
