Talvez deva tentar algumas variações de ortografia:
decrease sound » decrease sod (Expandir a busca), decrease soon (Expandir a busca), decrease and (Expandir a busca)
decreased risk » increased risk (Expandir a busca), decreased in (Expandir a busca)
toc decreased » to decreased (Expandir a busca), the decreased (Expandir a busca), not decreased (Expandir a busca)
risk decrease » risk decreases (Expandir a busca), risk increase (Expandir a busca), break decrease (Expandir a busca)
sound objects » and objects (Expandir a busca), sound effects (Expandir a busca), boundary objects (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 toc decreased risk decrease ) OR ( decrease NOT decrease sound objects ))~.
