Perhaps you should try some spelling variations:
"line modells" » "line models", "eines modells", "line model", "line modellls", "line modelslls", "online modells"
"murine model" » "murine models"
"linear mode" » "linear model", "linear models", "bilinear model"
"line mode" » "line model", "line models", "online mode"

Try widening your search to All Fields.

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: (((("line mode") OR ("linear mode"))) OR ((("line modells") OR ("murine model")))).
• Removing quotes may allow a broader search: (((( line mode ) or ( linear mode ))) or ((( line modells ) or ( murine model )))).
• Adding a wildcard symbol may retrieve word variants: (((("line mode") or ("linear mode"))) or ((("line modells") or ("murine model"))))*.
