    Neste artigo discute-se o problema da leitura e da formação de leitores no ensino superior, no Brasil e em Portugal, sendo nosso objetivo perceber se estes estudantes são ainda leitores em construção. A metodologia para a discussão centrou-se nas investigações em torno da formação leitora desses estudantes, o que permitiu chegar a algumas conclusões afins: são fundamentais estudos de maior dimensão nessas áreas; é basilar que todos os docentes do ensino superior tomem consciência das dificuldades desses alunos na leitura/escrita/literacias académicas e que nas suas disciplinas possam dar um contributo para colmatar esses problemas; os alunos do ensino superior são ainda leitores em construção.info:eu-repo/semantics/publishedVersio

    A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
