Perhaps you should try some spelling variations:
decreases processes » decrease processes (Expand search)
disease decreases » diseases decreases (Expand search), disease increases (Expand search), distance decreases (Expand search)
decrease during » increase during (Expand search), increases during (Expand search), increased during (Expand search)
during effluent » using effluent (Expand search), dyeing effluent (Expand search), farming effluent (Expand search)
decrease akt » decrease at (Expand search), decrease and (Expand search), decrease after (Expand search)
akt decrease » and decrease (Expand search), not decrease (Expand search), any decrease (Expand search)
akt disease » at disease (Expand search), rot disease (Expand search), not disease (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 disease decreases processes ) OR ( decrease akt decrease during effluent ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease akt disease decreases processes ) OR ( decrease akt decrease during effluent ))*.
