Talvez deva tentar algumas variações de ortografia:
functional roles » functional role (Expandir a busca), functional results (Expandir a busca), functional responses (Expandir a busca)
cases processes » cases processed (Expandir a busca), based processes (Expandir a busca), bases processos (Expandir a busca)
decrease rate » decreased rate (Expandir a busca), decreases rate (Expandir a busca), decrease at (Expandir a busca)
disease cases » disease case (Expandir a busca), disease caused (Expandir a busca), disease carta (Expandir a busca)
rate disease » rare disease (Expandir a busca), grade disease (Expandir a busca), grave disease (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• As palavras AND, OR e NOT pode ocasionar problemas na busca; tente utilizar as aspas: "(( decrease rate disease cases processes ) OR ( functional roles piton python programming ))~".
• Adicionar um caractere curinga pode recuperar variações da palavra buscada: (( decrease rate disease cases processes ) OR ( functional roles piton python programming ))*.
