decrease during » increase during (Expand search), increases during (Expand search), increased during (Expand search)
during decrease » during increased (Expand search), during depressed (Expand search), taping decrease (Expand search)
decrease costs » decreasing costs (Expand search), decreases post (Expand search), disease costs (Expand search)

decrease std » decrease sod (Expand search), decrease at (Expand search), decrease its (Expand search)
std object » and object (Expand search), 3d object (Expand search), ood object (Expand search)

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: (( decrease during decrease AND decreases ) OR ( decrease costs decrease std object ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease during decrease and decreases ) OR ( decrease costs decrease std object ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease during decrease and decreases ) OR ( decrease costs decrease std object ))*.
