decrease during » increase during (Expand search), increases during (Expand search), increased during (Expand search)
decrease that » decrease the (Expand search), decrease at (Expand search), decrees that (Expand search)
that decrease » that increase (Expand search), that increases (Expand search), not decrease (Expand search)
during effect » enduring effect (Expand search), curling effect (Expand search), pouring effect (Expand search)
decrease toc » decrease of (Expand search), decrease the (Expand search), decreased to (Expand search)

decrease α » decrease _ (Expand search), decrease β (Expand search), decrease in (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 toc decrease α decrease ) OR ( decrease that decrease during effect ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease toc decrease α decrease ) OR ( decrease that decrease during effect ))*.
