O papel da educação no mundo pós-pandemia: pela (re)fundação de uma pedagogia das virtudes com inspiração herbartiana
(2022) [Artigo de periódico]Johann Friederich Herbart não somente fundou a pedagogia como campo autônomo, mas tam-bém nos deixou um vasto legado científico e filosófico sobre tal área do conhecimento. O objetivo desse trabalho é resgatar conceitos ... -
Investigation of scalar and fermion dark matter in mono-photon production at high-energy colliders
(2024) [Artigo de periódico]Many theories about dark matter have emerged due to its strong theoretical appeal in explaining astrophysical phenomena. However, experimental and theoretical particle physics have yet not provided evidence that dark matter ... -
A gênese da interpretação probabilística em livros didáticos de mecânica quântica
(2024) [Artigo de periódico]Neste artigo propomos uma análise de vinte livros didáticos utilizados no ensino de Física em cursos de licenciatura e bacharelado, com o objetivo de investigar como eles abordam e justificam a interpretação probabilística ... -
The photon is naked : the role of textbook in the building of a common world
(2024) [Artigo de periódico]Given the ontological plurality associated with Quantum Theory (i.e., the multiplicity of interpretations of the theory), we investigated the approaches of 22 undergraduate textbooks in the process of composing a possible ... -
Probing small Bjorken-x nuclear gluonic structure via coherent J=ψ photoproduction in ultraperipheral Pb-Pb collisions at √s NN = 5.02 TeV
(2023) [Artigo de periódico]Quasireal photons exchanged in relativistic heavy ion interactions are powerful probes of the gluonic structure of nuclei. The coherent J / ψ photoproduction cross section in ultraperipheral lead-lead collisions is measured ... -
Measurements of the azimuthal anisotropy of prompt and nonprompt charmonia in PbPb collisions at √sNN = 5.02 TeV
(2023) [Artigo de periódico]The second-order (v2 ) and third-order (v3 ) Fourier coefcients describing the azimuthal anisotropy of prompt and nonprompt (from b-hadron decays) J/ψ, as well as prompt ψ(2S) mesons are measured in lead-lead collisions ... -
Sobre o direito de (re)existir e ser kilombola : o caso do licenciamento da BR 386 no Rio Grande do Sul
(2024) [Artigo de periódico]A partir de um estudo de caso, o licenciamento de ampliação da BR 386 no interior do Rio Grande do Sul, o artigo discute o conceito de racismo ambiental e apresenta as formas, os processos e as estratégias de abordagens ... -
Waterproofing of bottle gourd (Lagenaria siceraria) with castor oil polyurethane resin
(2020) [Artigo de periódico]Castor oil is widely used in chemical industry as raw material for paints, coatings, lubricants and a wide variety of other products. It is an important alternative to petrochemical feedstocks for the synthesis of polyurethanes ... -
Search for pair-produced vector-like leptons in final states with third-generation leptons and at least three b quark jets in proton-proton collisions at √s = 13 TeV
(2023) [Artigo de periódico]The first search is presented for vector-like leptons (VLLs) in the context of the “4321 model”, an ultraviolet-complete model with the potential to explain existing B physics measurements that are in tension with standard ... -
First measurement of Ω0c production in pp collisions at √s = 13 TeV
(2023) [Artigo de periódico]The inclusive production of the charm–strange baryo nΩ0c is measured for the first time via its hadronic decay into Ω−π+ at midrapidity (|y| < 0.5) in proton–proton (pp) collisions at the centre-of-mass energy√s = 13 TeV ...
