Talvez deva tentar algumas variações de ortografia:
decrease placement » decreased platelet (Expandir a busca), desse placement (Expandir a busca)
placement program » placement problem (Expandir a busca), payment program (Expandir a busca), enhancement program (Expandir a busca)
piton python » pitons python (Expandir a busca), in python (Expandir a busca), with python (Expandir a busca)
decrease to » decreased to (Expandir a busca), decrease toc (Expandir a busca), decrease the (Expandir a busca)
python cod » python code (Expandir a busca), python cuda (Expandir a busca), python and (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease to decrease placement program ) OR ( python cod piton python programming ))~.
