5. A nova definição do quilograma em termos da constante de Planck
Resumo A partir de 2019, a unidade de massa do Sistema Internacional de Unidades (SI), o quilograma, terá sua definição modificada. Deixará de ser o artefato metálico guardado na sede do BIPM, nos arredores de Paris, para ser baseado na constante de Planck (h). Qual é a necessidade desta mudança? E como as medidas são realizadas? São algumas das per

9. Variation of cuticular chemical compounds in three species of Mischocyttarus (Hymenoptera: Vespidae) eusocial wasps
Abstract The social wasps have a remarkable system of organization in which chemical communication mediate different behavioral interactions. Among the compounds involved in this process, cuticular hydrocarbons are considered the main signals for nestmate recognition, caste differentiation, and fertility communication. The aims of this study were to describe
