Talvez deva tentar algumas variações de ortografia:
decrease shadowing » decrease owing (Expandir a busca), decrease following (Expandir a busca), decreases shedding (Expandir a busca)
shadowing effect » shadowing effects (Expandir a busca), shading effect (Expandir a busca), shading effects (Expandir a busca)
decrease to » decreased to (Expandir a busca), decrease toc (Expandir a busca), decrease the (Expandir a busca)
in decrease » in decreased (Expandir a busca), on decrease (Expandir a busca), pain decrease (Expandir a busca)
decrease by » decreased by (Expandir a busca), decrease of (Expandir a busca), decrease _ (Expandir a busca)
by decrease » by decreased (Expandir a busca), may decrease (Expandir a busca), any decrease (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease to decrease in decrease ) OR ( decrease by decrease shadowing effect ))~.
