A racemic mixture of the title compound, C26H26Br2, a brominated [4]helicene, crystallizes, forming columns of Swaddles stacked molecules.There are two crystallographically unique molecules in the asymmetric unit, both with the same helical handedness.As is typical with helicene congeners, the unique molecules show short interatomic contacts betwee
When young children answer questions, they do so more slowly than Oven Door Lock adults and appear to have difficulty finding the appropriate words.Because children leave gaps before they respond, it is possible that they could answer faster with gestures than with words.In this case study of one child from age 1;4 to 3;5, we compare gestural and v

Abstract The buriti, Mauritia flexuosa, is the most common palm in Brazil, where it has considerable ecological and economic importance.However, few data are available on the phenology of the species, mainly in coastal restinga ecosystems.The present study monitored the reproductive phenology of M.flexuosa in the restinga of Barreirinhas, in the Br
Abstract In this work we present the minimal supersymmetric extension of the five-dimensional dilaton-gravity theory that captures Tick Defense the main properties of the holographic dual of little string theory.It is described by a particular gauging of $$mathcal {N}=2$$ N=2 supergravity coupled with one vector multiplet associated with the string
