Talvez deva tentar algumas variações de ortografia:
plc's programming » plc programming (Expandir a busca), c programming (Expandir a busca), block programming (Expandir a busca)
disease processes » disease process (Expandir a busca), disease progress (Expandir a busca), these processes (Expandir a busca)
decrease disease » decreases disease (Expandir a busca), increase disease (Expandir a busca), increased disease (Expandir a busca)
region plc's » region patos (Expandir a busca), region pcr (Expandir a busca)
decrease to » decreased to (Expandir a busca), decrease toc (Expandir a busca), decrease the (Expandir a busca)
python code » python redes (Expandir a busca)
code region » code regions (Expandir a busca), core region (Expandir a busca), cone region (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease to decrease disease processes ) OR ( python code region plc's programming ))~.
