Talvez deva tentar algumas variações de ortografia:
three procedures » the procedures (Expandir a busca), care procedures (Expandir a busca), valve procedures (Expandir a busca)
disease three » disease the (Expandir a busca), disease free (Expandir a busca), disease type (Expandir a busca)
python coding » action coding (Expandir a busca), python code (Expandir a busca)
coding pitons » loading pistons (Expandir a busca)
decrease and » decreases and (Expandir a busca), decrease in (Expandir a busca), decrease of (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease and disease three procedures ) OR ( python coding pitons python programming ))~.
