Two fish moving in their seas : how does the body language of teachers show itself who teach mathematical equations?
(2021) [Artigo de periódico]Background: “Culture hides much more than it reveals and, strangely enough, what it hides, it hides more effectively from its own participants” (Hall, 1959, p. 39). This quote corresponds well to a Persian proverb, also a ... -
Two interacting fermions in a one-dimensional harmonic trap : matching the Bethe ansatz and variational approaches
(2012) [Artigo de periódico]In this work, combining the Bethe ansatz approach with the variational principle, we calculate the ground-state energy of the relative motion of a system of two fermions with spin up and spin down interacting via a ... -
Two New Cynodonts (Therapsida) from the Middle-Early Late Triassic of Brazil and Comments on South American Probainognathians
(2016) [Artigo de periódico]We describe two new cynodonts from the early Late Triassic of southern Brazil. One taxon, Bonacynodon schultzi gen. et sp. nov., comes from the lower Carnian Dinodontosaurus AZ, being correlated with the faunal association ... -
Two new pulsating low-mass pre-white dwarfs or SX Phoenicis stars?
(2016) [Artigo de periódico]Context. The discovery of pulsations in low-mass stars opens an opportunity to probe their interiors and determine their evolution by employing the tools of asteroseismology. Aims. We aim to analyse high-speed photometry ... -
Two new species of Odontostilbe historically hidden under O. microcephala (Characiformes: Cheirodontinae)
(2018) [Artigo de periódico]Specimens historically identified as Odontostilbe microcephala from the upper rio Paraná and Andean piedmont tributaries of the río Paraguay are reviewed and split in three species. We found that the distribution of O. ... -
Two new troglobitic species of Scleropactidae (Crustacea: Isopoda: Oniscidea) from Pará, Brazil
(2011) [Artigo de periódico]The South America Scleropactidae includes 53 nominal species distributed in 14 genera. In Brazil, there are 16 species recorded in the north and southeast regions. Here, two new species of Scleropactidae are described based ... -
Two-particle azimuthal correlations in γp interactions using pPb collisions at √sNN = 8.16 TeV
(2023) [Artigo de periódico]The first measurements of the Fourier coefficients (Vn) of the azimuthal distributions of charged hadrons emitted from photon-proton (γp) interactions are presented. The data are extracted from 68.8 nb−1 of ultra-peripheral ... -
Two-particle differential transverse momentum and number density correlations in p−Pb collisions at 5.02 TeV and Pb-Pb collisions at 2.76 TeV at the CERN Large Hadron Collider
(2019) [Artigo de periódico]We present measurements of two-particle differential number correlation functionsR2and transverse momen-tum correlation functionsP2, obtained fromp-Pb collisions at 5.02 TeV and Pb-Pb collisions at 2.76 TeV. Theresults are ... -
Two-particle transverse momentum correlations in pp and p-Pb collisions at energies available at the CERN Large Hadron Collider
(2023) [Artigo de periódico]Two-particle transverse momentum differential correlators, recently measured in Pb-Pb collisions at energies available at the CERN Large Hadron Collider (LHC), provide an additional tool to gain insights into particle ... -
Two-pass friction stir welding of cladded API X65
(2020) [Artigo de periódico]Cladded materials are used by the oil and gas industry due to the combination of good mechanical properties and low cost of high-strength low-alloy steel (HSLA) API 5L X65 with the excellent corrosion resistance of the ... -

Two reddened globular cluster projected close to the galactic center : Palomar 6 and Djorgovski 1
(1995) [Artigo de periódico]We present NTT V,I observations of Palomar 6 and Djorgovski 1, two obscured loose clusters in crowded fields. We derive a reddening of E(B - V) = 1.33 ± 0.10, a distance dʘ ≈ 8.9 kpc, and a metallicity of [Fe/H] ≈ -0.4 for ... -
Two rubber balloons : phase diagram of air transfer
(2004) [Artigo de periódico]Two identical rubber balloons are partially inflated with air (to different extent) and connected by a hose with a valve. It is found that depending on initial balloon volumes, when the valve is opened the air will flow ... -
Two scenarios for superconductivity in CeRh2As2
(2021) [Artigo de periódico]CeRh2As2, a nonsymmorphic heavy fermion material, was recently reported to host a remarkable temperature versus z-axis magnetic-field phase diagram with two superconducting phases. In this material, the two inequivalent ... -
Two serendipitous low-mass lmc dusters discovered with hst
(1998) [Artigo de periódico]We present V and I photometry of two open clusters in the LMC down to V~26. The clusters were imaged with the Wide Field and Planetary Camera 2 (WFPC2) on board the Hubble Space Telescope (HST), as part of the Medium Deep ... -
A two-sided method for nonlinear equations with cubic convergence
