Perhaps you should try some spelling variations:
period programming » grid programming (Expand search), method programming (Expand search), end programming (Expand search)
decrease implicit » decade implicit (Expand search), verdade implicit (Expand search)
decreases change » decreases cancer (Expand search), decreases cocaine (Expand search), decreases and (Expand search)
change processes » change process (Expand search)
implicit period » implicit method (Expand search), implicit operation (Expand search), implicit methods (Expand search)
akt decreases » salt decreases (Expand search), and decreases (Expand search), but decreases (Expand search)
decrease akt » decrease at (Expand search), decrease and (Expand search), decrease after (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 akt decreases change processes ) OR ( AND decrease implicit period programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease akt decreases change processes ) OR ( AND decrease implicit period programming ))*.
