Talvez deva tentar algumas variações de ortografia:
discrete variable » discrete variables (Expandir a busca)
variable pattern » variable matter (Expandir a busca), variate pattern (Expandir a busca), variable water (Expandir a busca)
decrease lipid » increases lipid (Expandir a busca), increased lipid (Expandir a busca)
lipid decrease » rapid decrease (Expandir a busca), ligand decrease (Expandir a busca), limb decrease (Expandir a busca)
decrease fear » decreased fear (Expandir a busca), decrease fetal (Expandir a busca), decreased heart (Expandir a busca)
fear discrete » four discrete (Expandir a busca), linear discrete (Expandir a busca), their discrete (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease lipid decrease AND decrease ) OR ( decrease fear discrete variable pattern ))~.
