Perhaps you should try some spelling variations:
novel preprocessing » novel processing (Expand search), noise preprocessing (Expand search), the preprocessing (Expand search)
during depressed » during depressive (Expand search), during repressive (Expand search), feeling depressed (Expand search)
decrease during » increase during (Expand search), increases during (Expand search), increased during (Expand search)
depressed novel » depressao nivel (Expand search), depressed women (Expand search), depressed mother (Expand search)
decrease toc » decrease of (Expand search), decrease the (Expand search), decreased to (Expand search)
toc decrease » to decrease (Expand search), the decrease (Expand search), not decrease (Expand search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( decrease during depressed novel preprocessing ) OR ( decrease toc decrease NOT decrease ))~.
