A ciência que não vemos: o jornalismo literário como meio de desvelamento de ideologias e polifonia na comunicação pública da ciência
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ciência, Tecnologia e Sociedade - PPGCTS, 2010-02-25)
From a diagnosis according to which there is a gap between common people and the research and development institutions, some studies in the public communication of science aim to gather solutions for reducing it a process ...

Ion acoustic damping effects on parametric decays of Alfvén waves: Right-hand polarization
(Blackwell Publishing Ltd, 2001)
We study ion acoustic damping effects on parametric decays of right-hand-polarized electromagnetic waves. We do this because ion beams have been observed in a variety of space environments, and consequently, these waves ...
Incoherent scatter radar estimation of F region ionospheric composition during frictional heating events
(Blackwell Publishing Ltd, 2011)
A method is developed for estimating F region ion composition from incoherent scatter radar (ISR) measurements during times of frictional ion heating. The technique addresses ion temperature-mass ambiguities in the IS ...
Phase transition-like behavior of the magnetosphere during substorms
(Blackwell Publishing Ltd, 2000)
The behavior of substorms as sudden transitions of the magnetosphere is studied using the Bargatze et al. [1985] data set of the solar wind induced electric field vBs and the auroral electrojet index AL. The data set is ...
Self-organized criticality in the substorm phenomenon and its relation to localized reconnection in the magnetospheric plasma sheet
(Blackwell Publishing Ltd, 2000)
Evidence is presented that suggests that there is a significant self-organized criticality (SOC) component in the dynamics of substorms in the magnetosphere. We assume that observations of bursty bulk flows, fast flows, ...
Parametric decays, stabilization effects, and electrostatic instabilities due to finite-amplitude Alfvén waves in a fast solar wind-like plasma
(Blackwell Publishing Ltd, 2007)
The effects of a finite-amplitude Alfvén wave in a plasma system with a proton and an alpha-particle beam, are studied. The system is described by a fourteenth-order polynomial providing, thereby, many decay channels for ...
Particle-in-cell simulation of incoherent scatter radar spectral distortions related to beam-plasma interactions in the auroral ionosphere
(Blackwell Publishing Ltd, 2011)
An electrostatic parallel particle-in-cell (EPPIC) code that allows for particle beam injections and multiple boundary conditions is used to investigate the beam-plasma interaction and its manifestations in the incoherent ...
Science, catholicism and politics in Argentina (1910-1935)
(Cambridge University Press, 2020-06)
In fin de siècle Argentina a secularist ideology of science was part of the positivist world view espoused by liberals and socialists. Between the years 1910 and 1935, a period in which the Catholic Church experienced a ...
The Bibliometric Literature on Scopus and WoS: The Medicine and Environmental Sciences Categories as Case of Study
In a broad sense, science can be understood as the knowledge contained in scientific manuscripts published in scientific journals. Scientific databases index only those journals that reach certain quality standards. ...
