Talvez deva tentar algumas variações de ortografia:
decrease reporting » increase reporting (Expandir a busca), disease reporting (Expandir a busca), decrease replacing (Expandir a busca)
reporting object » reporting effect (Expandir a busca), reporting affects (Expandir a busca), learning object (Expandir a busca)
decrease at » decrease akt (Expandir a busca), decrease and (Expandir a busca), decrease of (Expandir a busca)
at decrease » rate decrease (Expandir a busca), that decrease (Expandir a busca), and decrease (Expandir a busca)
in decrease » in decreased (Expandir a busca), on decrease (Expandir a busca), pain decrease (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease at decrease OR decrease ) OR ( decrease in decrease reporting object ))~.
