O consenso científico sobre aquecimento global antropogênico : considerações históricas e epistemológicas e reflexões para o ensino dessa temática
(2018) [Artículo de periódico]Um dos desafios da educação ambiental para o século XXI é a inserção da temática do aquecimento global ou mudanças climáticas na sala de aula escolar. A natureza complexa do tema torna difícil a tarefa do(a) professor(a) ... -
Conservação de corrente elétrica num circuito elementar : o que os alunos pensam a respeito
(1986) [Artículo de periódico]Resumo não disponível -
Conservação e desenvolvimento de comunidades tradicionais : o caso de Chimanimani no centro de Moçambique
(2011) [Artículo de periódico]O artigo pretende discutir a transformação de uma área comunitária em conservação, a partir da introdução dos objetivos de desenvolvimento junto aos de conservação. A área geográfica escolhida para a análise é a Área de ... -
Considerações sobre a Sudesul: formação e modernização territorial
(2020) [Artículo de periódico]A partir do contexto histórico das primeira metade do século XX, se busca demonstrar a necessidade do governo central de desenvolver e integrar a fronteira sudoeste do Brasil. Esse processo fundou experiências de planejamento, ... -

Consistent description of ion-specificity in bulk and at interfaces by solvent implicit simulations and mean-field theory
(2020) [Artículo de periódico]Solvent-implicit Monte Carlo (MC) simulations and mean-field theory are used to predict activity coefficients and excess interfacial tensions for NaF, NaCl, NaI, KF, KCl, and KI solutions in good agreement with experimental ... -
A consistent noncommutative field theory : the Wess-Zumino model
(2000) [Artículo de periódico]We show that the noncommutative Wess–Zumino model is renormalizable to all orders of perturbation theory. The noncommutative scalar potential by itself is non-renormalizable but the Yukawa terms demanded by supersymmetry ... -
Constraining gluon distributions in nuclei using dijets in proton-proton and proton-pead collisions at √sNN=5.02 TeV
(2018) [Artículo de periódico]The pseudorapidity distributions of dijets as functions of their average transverse momentum (PTave) are measured in proton-lead (pPb) and proton-proton (pp) collisions. The data samples were collected by the CMS experiment ... -
Constraining hadronization mechanisms with Λ+c /D0 production ratios in Pb–Pb collisions at √sNN = 5.02 TeV
(2023) [Artículo de periódico]The production of prompt Λ+c baryons at midrapidity (|y| < 0.5) was measured in central (0–10%) and mid-central (30–50%) Pb–Pb collisions at the center-of-mass energy per nucleon–nucleon pair √sNN = 5.02 TeV with the ALICE ... -
Constraining radio mode feedback in galaxy clusters with the cluster radio AGNs properties to z ∼ 1
(2020) [Artículo de periódico]We study the properties of the Sydney University Molonglo Sky Survey (SUMSS) 843 MHz radio active galactic nuclei (AGNs) population in galaxy clusters from two large catalogues created using the Dark Energy Survey (DES): ... -
Constraining the Chiral Magnetic Effect with charge-dependent azimuthal correlations in Pb-Pb collisions at √sNN = 2.76 and 5.02 TeV
(2020) [Artículo de periódico]Systematic studies of charge-dependent two- and three-particle correlations in Pb-Pb collisions at √ sNN = 2.76 and 5.02 TeV used to probe the Chiral Magnetic Effect (CME) are presented. These measurements are performed ... -
Constraining the evolution of ZZ Ceti
(2003) [Artículo de periódico]We report our analysis of the stability of pulsation periods in the DAV star (pulsating hydrogen atmosphere white dwarf ) ZZ Ceti, also called R548. On the basis of observations that span 31 years, we conclude that the ... -
Constraining the free parameter of the high parton density effects
(2000) [Artículo de periódico]The high parton density effects are strongly dependent of the spatial gluon distribution within the proton, with radius R, which cannot be derived from perturbative QCD. In this paper we assume that the unitarity corrections ... -
Constraining the KN coupled channel dynamics using femtoscopic correlations at the LHC
(2023) [Artículo de periódico]The interaction of K−with protons is characterised by the presence of several coupled channels, systems like K0 n and π with a similar mass and the same quantum numbers as the K−p state. The strengths of these couplings ... -
Constraining the LMC cluster age gap : Washington photometry of NGC 2155 and SL 896 (LW 480)
(2002) [Artículo de periódico]We carried out Washington system photometry of the intermediate-age Large Magellanic Cloud (LMC) star clusters NGC2155 and SL 896 (LW480). We derive ages and metallicities from the T1 versus C - T1 colour–magnitude diagrams ... -
Constraining the magnitude of the Chiral Magnetic Effect with Event Shape Engineering in Pb–Pb collisions at √sNN=2.76TeV
(2018) [Artículo de periódico]In ultrarelativistic heavy-ion collisions, the event-by-event variation of the elliptic flow v2reflects fluctuations in the shape of the initial state of the system. This allows to select events with the same centrality ... -
Constraining the star formation rate in the solar neighbourhood with star clusters
(2011) [Artículo de periódico]This paper investigates the star formation rate (SFR) in the solar neighbourhood. First, we build the local age distribution function (ADF) with an updated sample of 442 star clusters located at less than 1 kpc from the ... -
Constraint-driven test scheduling for NoC-based systems
(2006) [Artículo de periódico]On-chip integrated network, the so-called networkon- chip (NoC), is becoming a promising communication paradigm for the next-generation embedded core-based system chips. The reuse of the on-chip network as test access ... -
