Leaching of atrazine in commercial and xerogel formulations in oxisol using bioassay and chromatographic methods
(2015) [Artigo de periódico]Mobility of atrazine in soil has contributed to the detection of levels above the legal limit in surface water and groundwater in Europe and the United States. The use of new formulations can reduce or minimize the impacts ... -
The Mato Perso Conduit System: evidence of silicic magma transport in the southern portion of the Paraná-Etendeka LIP, Brazil
(2017) [Artigo de periódico]The Mato Perso Conduit System is described from a ~ 120 km2 area in south Brazil exposing silicic volcanics of the Paraná-Etendeka LIP. A volcanic succession is defined by basaltic flows covered by flat-lying oxidized ... -
Zircon U-Pb geochronology, Sm-Nd and Pb-Pb isotope systematics of Ediacaran post-collisional high-silica Acampamento Velho volcanism at the Tupanci area, NW of the Sul-Rio-Grandense Shield, Brazil
(2017) [Artigo de periódico]We present new U-Pb zircon ages and Sm-Nd-Pb isotopic data for volcanic and hypabyssal acid rocks from the northernmost exposure of the Acampamento Velho Formation in the NW portion of the Sul-Rio-Grandense Shield, Brazil. ... -
Apnea recognition with wavelet neural networks
(2018) [Artigo de periódico]Apnea is a Sleep Disorder Syndrome characterized by an interruption or reduction of air flow for at least 10 seconds. Polysomnography is a test used to apnea diagnosis. Several signals, including Electrocardiogram (ECG), ... -
Search for disappearing tracks as a signature of new long-lived particles in proton-proton collisions at √s =13 TeV
(2018) [Artigo de periódico]A search is presented for long-lived charged particles that decay within the CMS detector and produce the signature of a disappearing track. A disappearing track is an isolated track with missing hits in the outer layers ... -
Search for third-generation scalar leptoquarks decaying to a top quark and a τ lepton at √s = 13TeV
(2018) [Artigo de periódico]A search for pair production of heavy scalar leptoquarks (LQs), each decaying into a top quark and a τ lepton, is presented. The search considers final states with an electron or a muon, one or two τ leptons that decayed ... -
On the counterpropagation of waves
(2019) [Artigo de periódico]This work analyses the counterpropagation of transversal plane waves in a linear, homogeneous, nondispersive, and isotropic medium. Although this is a traditional subject in disciplines associated with wave phenomena, a ... -
Neutral pion and η meson production at midrapidity in Pb-Pb collisions at √sNN = 2.76 TeV
(2018) [Artigo de periódico]Neutral pion and η meson production in the transverse momentum range 1 < pT < 20 GeV/c have been measured at midrapidity by the ALICE experiment at the Large Hadron Collider (LHC) in central and semicentral Pb-Pb collisions ... -
Seleção de variáveis para clusterização de bateladas produtivas através de ACP e remapeamento kernel
(2015) [Artigo de periódico]Técnicas de clusterização visam à formação de grupos de observações homogêneas dentro de um mesmo grupo e significativamente distintas das observações inseridas em outros grupos. Em processos industriais cuja produção é ... -
Measurement of the Z/γ∗ → ττ cross section in pp collisions at √s = 13TeV and validation of τ lepton analysis techniques
(2018) [Artigo de periódico]A measurement is presented of the Z/γ ∗ → ττ cross section in pp collisions at √ s = 13 TeV, using data recorded by the CMS experiment at the LHC, corresponding to an integrated luminosity of 2.3 fb−1. The product of the ...
