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)
based processes » based process (Expand search), and processes (Expand search)
implicit period » implicit method (Expand search), implicit operation (Expand search), implicit methods (Expand search)
disease based » disease caused (Expand search), disease case (Expand search), diseases caused (Expand search)
decrease rot » decreases ros (Expand search), decrease of (Expand search), decrease at (Expand search)
rot disease » host disease (Expand search), spot disease (Expand search), goat diseases (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 rot disease based processes ) OR ( AND decrease implicit period programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease rot disease based processes ) OR ( AND decrease implicit period programming ))*.
