Perhaps you should try some spelling variations:
"partially accelerated" » "particle accelerator", "partially correlated", "partially integrated"
"particle accelerated" » "particles accelerated", "particle accelerator", "particle acceleraton", "particles acceleratedd", "particle acceleratord", "particle acceleratond"
"particle accelerate" » "particles accelerated", "particle accelerator", "particle acceleraton"
"particle accelerators" » "particle accelerator", "particle acceleration", "particle accelerating"

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: (((("particle accelerators") OR ("particle accelerate"))) OR ((("particle accelerated") OR ("partially accelerated")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"particle accelerators\") OR (\"particle accelerate\"))) or (((\"particle accelerated\") or (\"partially accelerated\"))))".
• Removing quotes may allow a broader search: (((( particle accelerators ) OR ( particle accelerate ))) or ((( particle accelerated ) or ( partially accelerated )))).
• Adding a wildcard symbol may retrieve word variants: (((("particle accelerators") OR ("particle accelerate"))) or ((("particle accelerated") or ("partially accelerated"))))*.
