Talvez debería tentar con algunhas variantes ortográficas:
operation instrumentation » applications instrumentation, therapy instrumentation, modern instrumentation
instrumentation general » instrumentation energy, instrumentation external, instrumentation control
general functions » generic functions, central functions, cerebral functions
image stacks » gate stacks, image space, image tricks
gate » game, gae

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: operation instrumentation general functions ((image stacks) OR (((gate OR gave) OR gale) stacks))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "operation instrumentation general functions ((image stacks) or (((gate OR gave) or gale) stacks))~".
• Adding a wildcard symbol may retrieve word variants: operation instrumentation general functions ((image stacks) or (((gate OR gave) or gale) stacks))*.
