Perhaps you should try some spelling variations:
health temperance » health temperature, health tolerance, health temperament
network synthesis » network systems
health incidence » death incidence, health incident, health evidence
health impedance » health importance, head impedance, health imperative
health science » health sciences
nets synthesis » net synthesis, dots synthesis, its synthesis

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