Talvez deva tentar algumas variações de ortografia:
decreases processes » decrease processes (Expandir a busca)
disease decreases » disease increased (Expandir a busca), disease cases (Expandir a busca), disease disease (Expandir a busca)
testing program » testing programs (Expandir a busca), teaching program (Expandir a busca), visiting program (Expandir a busca)
python coding » action coding (Expandir a busca), python code (Expandir a busca)
scale testing » scale fishing (Expandir a busca), scale using (Expandir a busca), scale tests (Expandir a busca)
coding scale » coping scale (Expandir a busca), scoring scale (Expandir a busca), bonding scale (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease _ disease decreases processes ) OR ( python coding scale testing program ))~.
