Perhaps you should try some spelling variations:
networks synthesis » networks systems, nets synthesis
health influence » heart influence, death influence, hemath influence
health impedance » health importance, health temperance, head impedance
health tolerance » health governance, health temperance, reality tolerance
earth influence » heart influence, early influence, birth influence
heat tolerance » plant tolerance, salt tolerance, cell tolerance

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