Talvez deva tentar algumas variações de ortografia:
decrease hawking » decrease walking (Expandir a busca), decrease owing (Expandir a busca), decreases handling (Expandir a busca)
decrease during » increase during (Expandir a busca), increases during (Expandir a busca), increased during (Expandir a busca)
during decrease » during increased (Expandir a busca), during depressed (Expandir a busca), during disease (Expandir a busca)
hawking effect » healing effect (Expandir a busca), aging effect (Expandir a busca), heating effect (Expandir a busca)
decrease to » decreased to (Expandir a busca), decrease toc (Expandir a busca), decrease the (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease during decrease NOT decrease ) OR ( decrease to decrease hawking effect ))~.
