Perhaps you should try some spelling variations:
"particles accelerated" » "particles acceleration", "lattices accelerated", "particle acceleraton"
"partially accelerated" » "partially correlated", "naturally accelerate", "partially averaged"
"partially integrated" » "vertically integrated", "partially saturated", "fractionally integrated"
"particle accelerators" » "particle accelerate", "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 accelerator") OR ((((("particle accelerators") OR ("particle acceleration"))) OR ((("particles accelerated") OR ((("partially accelerated") OR ("partially integrated")))))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"particle accelerator\") or (((((\"particle accelerators\") or (\"particle acceleration\"))) or (((\"particles accelerated\") or (((\"partially accelerated\") OR (\"partially integrated\"))))))))".
• Removing quotes may allow a broader search: (( particle accelerator ) or ((((( particle accelerators ) or ( particle acceleration ))) or ((( particles accelerated ) or ((( partially accelerated ) OR ( partially integrated )))))))).
• Adding a wildcard symbol may retrieve word variants: (("particle accelerator") or ((((("particle accelerators") or ("particle acceleration"))) or ((("particles accelerated") or ((("partially accelerated") OR ("partially integrated"))))))))*.
