Talvez deva tentar algumas variações de ortografia:
in discharges » in discharge (Expandir a busca), zinc discharges (Expandir a busca), and discharges (Expandir a busca)
discharges in » discharge in (Expandir a busca), discharge and (Expandir a busca)
in properties » on properties (Expandir a busca)
python coding » action coding (Expandir a busca), python code (Expandir a busca)
coding python » codigo python (Expandir a busca), codigos python (Expandir a busca), using python (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease in discharges in properties ) OR ( python coding python python programming ))~.
