Perhaps you should try some spelling variations:
pfirst review » first reviews, fast review, fiat review
first revised » first rise, first reviews, part revised
sensor them » sensor thermo, sensor tm, sensor thermal
iet world » iot world, net world, ict world
2008 iet » 2008 ieee

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: 2008 iet world ((((pfirst review) OR (first revised))) OR (first review)) sensor them.
• The words AND, OR and NOT may confuse the search; try adding quotes: "2008 iet world ((((pfirst review) OR (first revised))) or (first review)) sensor them".
• Adding a wildcard symbol may retrieve word variants: 2008 iet world ((((pfirst review) OR (first revised))) or (first review)) sensor them*.
