Talvez debería tentar con algunhas variantes ortográficas:
ionization instrumentation » operation instrumentation, radiation instrumentation, collection instrumentation
instrumentation theory » instrumentation methods, instrumentation https, instruction theory
theory decision » theory design
basic linear » quasi linear, basic life
class linear » mass linear, class library, class life

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: ionization instrumentation theory decision ((basic linear) OR (((class linear) OR (less linear))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ionization instrumentation theory decision ((basic linear) or (((class linear) OR (less linear))))~".
• Adding a wildcard symbol may retrieve word variants: ionization instrumentation theory decision ((basic linear) or (((class linear) OR (less linear))))*.
