decrease that » decrease the (Expand search), decrease at (Expand search), decrees that (Expand search)
increases akt » increases anti (Expand search), increases and (Expand search), increases ck (Expand search)
decrease can » decrease and (Expand search), decrease at (Expand search), decrease on (Expand search)
can decrease » can increase (Expand search), and decrease (Expand search), to decrease (Expand search)
in professor » in professors (Expand search), and professor (Expand search), ai professor (Expand search)
akt decrease » and decrease (Expand search), not decrease (Expand search), any decrease (Expand search)

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: "(( decrease can decrease in professor ) OR ( decrease that increases akt decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease can decrease in professor ) OR ( decrease that increases akt decrease ))*.
