Talvez deva tentar algumas variações de ortografia:
decrease burden » disease burden (Expandir a busca), decrease further (Expandir a busca)
burden process » burning process (Expandir a busca), green process (Expandir a busca), maden process (Expandir a busca)
pattern python » pattern action (Expandir a busca), pattern method (Expandir a busca)
based pattern » based battery (Expandir a busca), based plasters (Expandir a busca), mapped pattern (Expandir a busca)
python based » action based (Expandir a busca)
in decrease » in decreased (Expandir a busca), on decrease (Expandir a busca), pain decrease (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease in decrease burden process ) OR ( python based pattern python programming ))~.
