Talvez deva tentar algumas variações de ortografia:
discharges the » discharges with (Expandir a busca), discharges in (Expandir a busca), discharges of (Expandir a busca)
the processing » the process (Expandir a busca), image processing (Expandir a busca)
of discharges » of discharge (Expandir a busca), glow discharges (Expandir a busca), arc discharges (Expandir a busca)
python codigo » python coding (Expandir a busca), python code (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
decrease of » decrease in (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease of discharges the processing ) OR ( python codigo python python programming ))~.
