Talvez deva tentar algumas variações de ortografia:
decreases spreading » disease spreading (Expandir a busca), decreases weaning (Expandir a busca)
spreading objects » speaking objects (Expandir a busca), spreading spects (Expandir a busca), leaming objects (Expandir a busca)
decrease costs » decreasing costs (Expandir a busca), decreases post (Expandir a busca), disease costs (Expandir a busca)
costs decrease » loss decrease (Expandir a busca), not decrease (Expandir a busca), cells decrease (Expandir a busca)
decrease rate » decreased rate (Expandir a busca), decreases rate (Expandir a busca), decrease at (Expandir a busca)
rate decrease » rats decreases (Expandir a busca), rate increase (Expandir a busca), to decrease (Expandir a busca)
toc decreases » c decreases (Expandir a busca), oic decreases (Expandir a busca), co2 decreases (Expandir a busca)
decrease toc » decrease of (Expandir a busca), decrease the (Expandir a busca), decreased to (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease costs decrease rate decrease ) OR ( decrease toc decreases spreading objects ))~.
