Talvez deva tentar algumas variações de ortografia:
case processes » care processes (Expandir a busca), caso processes (Expandir a busca), cases processed (Expandir a busca)
decrease sod » decrease std (Expandir a busca), decrease food (Expandir a busca), decrease of (Expandir a busca)
sod disease » pod disease (Expandir a busca), cord disease (Expandir a busca), food disease (Expandir a busca)
python 2a » python _ (Expandir a busca), python c (Expandir a busca), python to (Expandir a busca)
2a pitons » _ pitons (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease sod disease case processes ) OR ( python 2a pitons python programming ))~.
