Talvez deva tentar algumas variações de ortografia:
vpython programming » python programming (Expandir a busca), method programming (Expandir a busca), creation programming (Expandir a busca)
decreases disease » diseases disease (Expandir a busca), decreases adipose (Expandir a busca), decreases breast (Expandir a busca)
disease processes » disease process (Expandir a busca), disease progress (Expandir a busca), these processes (Expandir a busca)
codigos vpython » codigos python (Expandir a busca), codigo python (Expandir a busca)
coding codigos » codigo codigo (Expandir a busca), code codigos (Expandir a busca)
hiv decreases » oil decreases (Expandir a busca), oic decreases (Expandir a busca), ivm decreases (Expandir a busca)
python coding » action coding (Expandir a busca), python code (Expandir a busca)
decrease hiv » decrease in (Expandir a busca), decrease their (Expandir a busca), decreased high (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease hiv decreases disease processes ) OR ( python coding codigos vpython programming ))~.
