Perhaps you should try some spelling variations:
primate visual » primary visual
does primate » does private, does climate, does primary
visual time » usual time, visual regime, visual types
gift world » iot world, bit world, gatt world
ict world » iot world, int world, mixt world

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "2008 ((ict world) OR (gift world)) does primate visual time".
• Adding a wildcard symbol may retrieve word variants: 2008 ((ict world) OR (gift world)) does primate visual time*.
