Perhaps you should try some spelling variations:
"schriften zur management" » "schriften fur management", "schriften our management", "schriften your management", "vorschriften zur management", "schriften des management"
"schriften icu management" » "schriften ii management", "schriften i management", "schriften im management"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"schriften zur management\") OR (\"schriften icu management\"))".
• Removing quotes may allow a broader search: (( schriften zur management ) OR ( schriften icu management )).
• Adding a wildcard symbol may retrieve word variants: (("schriften zur management") OR ("schriften icu management"))*.
