Talvez deva tentar algumas variações de ortografia:
decrease burden » disease burden (Expandir a busca), decrease further (Expandir a busca)
burden disease » bursal disease (Expandir a busca)
disease year » disease heart (Expandir a busca), disease yeast (Expandir a busca), disease yel (Expandir a busca)
year program » linear program (Expandir a busca), gestar program (Expandir a busca)
python code » python coding (Expandir a busca), python redes (Expandir a busca)
code java » codes java (Expandir a busca), xcode java (Expandir a busca), ide java (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease burden disease year program ) OR ( python code java python programming ))~.
