Perhaps you should try some spelling variations:
health impedance » health importance, health temperance, head impedance
health science » health sciences
work synthesis » world synthesis, walk synthesis, shock synthesis
health devices » health device, health services, health service
systems report » system report, systems support, systems recent
science work » science works, science world, science where
health dence » health device, health evidence, health degree

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