Perhaps you should try some spelling variations:
sequential networks » terrestrial networks
networks synthesis » networks systems, nets synthesis
network synthesis » network systems
health incidence » death incidence, health incident, health science
guidance network » guide network, finance network, guided 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 ((networks synthesis) OR (network synthesis)) report ) OR ( health ((sequential network) OR (sequential networks)) synthesis report ))) OR ( health ((guidance network) OR (impedance network)) synthesis report )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( health incidence ((networks synthesis) OR (network synthesis)) report ) or ( health ((sequential network) or (sequential networks)) synthesis report ))) or ( health ((guidance network) or (impedance network)) synthesis report ))".
• Adding a wildcard symbol may retrieve word variants: (((( health incidence ((networks synthesis) OR (network synthesis)) report ) or ( health ((sequential network) or (sequential networks)) synthesis report ))) or ( health ((guidance network) or (impedance network)) synthesis report ))*.
