Resumo Foi feito um estudo abordando os aspectos fenológicos, ecológicos e de produtividade do Pajurá (Couepia bracteosa Bentham.) para a região de Manaus. A espécie floresce na época mais chuvosa e frutifica no fi...

Resumo Foram feitas comparações anatômicas entre folhas de plantas diplóides e poliplóides do clone IAN 717 do híbrido Hevea brasiliensis x benthamiana. Em termos gerais, foram encontrados aumentos em tamanho signi...

O óleo essencial das folhas de Eucalyptus benthamii Maiden et Cambage, espécie de elevada resistência ao frio, contém α-pineno como constituinte majoritário. Este trabalho avaliou a anatomia foliar de E. benthamii ...

ABSTRACT Upstream open reading frames (uORFs) are regulatory elements present in the 5′ leaders of mRNA that can significantly impact downstream gene expression in eukaryotes. In crop engineering, editing of uORFs can ...

Mankind is, at its most primal form, predatory. If one were to take a look back at humanity’s past, one would be confronted with the fact that our ancestors were not very different in comparison to the wildlife around ...

Resumo O presente artigo tem por objetivo examinar de que forma o contexto histórico-filosófico do século XIX influenciou a compreensão nietzschiana acerca do ascetismo. Para tanto, foi necessário se afastar da obra...
