Manuais acadêmicos de química geral em língua portuguesa: aspectos lingüísticos terminológicos e aspectos conceituais
(2002) [Artigo de periódico]Este artigo apresenta os primeiros resultados de uma pesquisa interdisciplinar em andamento desde março de 2001. promovida pela Área de Educação Química da UFRGS (AEQ/UFRGS) com a cooperação do Projeto TERMISUL. Nessa ... -
Descentralização política e gestão territorial no Rio Grande do Sul (Brasil) : tendências recentes

Search for physics beyond the standard model in events with high-momentum Higgs bosons and missing transverse momentum in proton-proton collisions at 13 TeV
(2018) [Artigo de periódico]A search for physics beyond the standard model in events with one or more high-momentum Higgs bosons, H, decaying to pairs of b quarks in association with missing transverse momentum is presented. The data, corresponding ... -
Hyperchaotic dynamics for light polarization in a laser diode
(2018) [Artigo de periódico]It is shown that a highly randomlike behavior of light polarization states in the output of a free-running laser diode, covering the whole Poincar´e sphere, arises as a result from a fully deterministic nonlinear process, ... -
Observation of t¯tH production
(2018) [Artigo de periódico]The observation of Higgs boson production in association with a top quark-antiquark pair is reported, based on a combined analysis of proton-proton collision data at center-of-mass energies of ffiffiffi s p ¼ 7, 8, and 13 ... -
Deep SOAR follow-up photometry of two Milky Way outer-halo companions discovered with Dark Energy Survey
(2018) [Artigo de periódico]We report the discovery of a new star cluster, DES 3, in the constellation of Indus, and deeper observations of the previously identified satellite DES J0222.7−5217 (Eridanus III). DES 3 was detected as a stellar overdensity ... -
Search for new physics in final states with an energetic jet or a hadronically decaying W or Z boson and transverse momentum imbalance at √s = 13 TeV
(2018) [Artigo de periódico]A search for new physics using events containing an imbalance in transverse momentum and one or more energetic jets arising from initial-state radiation or the hadronic decay of W or Z bosons is presented. A data sample ... -
Search for heavy neutral leptons in events with three charged leptons in proton-proton collisions at √s=13 TeV
(2018) [Artigo de periódico]A search for a heavy neutral lepton N of Majorana nature decaying into a W boson and a charged lepton is performed using the CMS detector at the LHC. The targeted signature consists of three prompt charged leptons in any ... -
Heavy meson photoproduction in peripheral AA collisions
(2018) [Artigo de periódico]The exclusive photoproduction of the heavy vector mesons ψ and Y is investigated in peripheral Pb-Pb collisions for the energies available at the LHC, ffiffiffi sp ¼ 2.76 TeV and ffiffiffi ps ¼ 5.02 TeV. To evaluate the ... -
Measurement of differential cross sections for the production of top quark pairs and of additional jets in lepton + jets events from pp collisions at √s = 13 TeV
(2018) [Artigo de periódico]Differential and double-differential cross sections for the production of top quark pairs in proton-proton collisions at ffiffiffi s p ¼ 13 TeV are measured as a function of kinematic variables of the top quarks and the ...
