Talvez deva tentar algumas variações de ortografia:
sequential methane » sequential method (Expandir a busca), sequential mean (Expandir a busca), sequential machine (Expandir a busca)
their sequential » the sequential (Expandir a busca), their essential (Expandir a busca), hour sequential (Expandir a busca)
methane process » membrane process (Expandir a busca), ethanol process (Expandir a busca), method process (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
using python » usando python (Expandir a busca), in python (Expandir a busca)
coder their » over their (Expandir a busca), lower their (Expandir a busca), under their (Expandir a busca)
using using » housing using (Expandir a busca), aging using (Expandir a busca), sensing using (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder their sequential methane process ) OR ( using using python python programming ))~.
