Talvez deva tentar algumas variações de ortografia:
decrease observed » decay observed (Expandir a busca), case observed (Expandir a busca)
observed objects » observed effects (Expandir a busca), submerged objects (Expandir a busca), buried objects (Expandir a busca)
increase blood » increases blood (Expandir a busca), increased blood (Expandir a busca), decreases blood (Expandir a busca)
blood decrease » blood degree (Expandir a busca), blood disease (Expandir a busca), loss decrease (Expandir a busca)
decrease the » decreases the (Expandir a busca), decrease in (Expandir a busca), decrease of (Expandir a busca)
the decrease » to decrease (Expandir a busca), and decrease (Expandir a busca)
decrease on » decrease in (Expandir a busca), decrease of (Expandir a busca), decrease or (Expandir a busca)
on decrease » on decreased (Expandir a busca), of decrease (Expandir a busca), or decrease (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( increase blood decrease on decrease ) OR ( decrease the decrease observed objects ))~.
