Emergent universe revisited through the CSL theory
(Springer, 2021-12)
In this work we analyze how the spectrum of primordial scalar perturbations is modified, within the emergent universe scenario, when a particular version of the Continuous Spontaneous Localization (CSL) model is incorporated ...
Milagro limits and HAWC sensitivity for the rate-density of evaporating Primordial Black Holes
(2014)
Primordial Black Holes (PBHs) are gravitationally collapsed objects that may have been created by density fluctuations in the early universe and could have arbitrarily small masses down to the Planck scale. Hawking showed ...
Growing Classical and Quantum Entropies in the Early Universe
(Springer/plenum Publishers, 2009-12)
Following the idea that the global and local arrow of time has a cosmological origin, we define an entropy in the classical and in the quantum periods of the universe evolution. For the quantum period a semi-classical ...

Constraining quantum collapse inflationary models with current data: The semiclassical approach
(World Scientific, 2018-12)
The hypothesis of the self-induced collapse of the inflaton wave function was introduced as a candidate for the physical process responsible for the emergence of inhomogeneity and anisotropy at all scales. In particular, ...
A Jacobian elliptic single-field inflation
(Springer, 2015-06)
In the scenario of single-field inflation, this field is described in terms of Jacobian elliptic functions. This approach provides, when constrained to particular cases, analytic solutions already known in the past, ...
The impact of particle production on gravitational baryogenesis
(2016-11-10)
Baryogenesis driven by curvature effects is investigated by taking into account gravitationally induced particle production in the very early Universe. In our scenario, the baryon asymmetry is generated dynamically during ...
Correlates of blood pressure according to early, on time, and late maturation in adolescents
(Wiley-Blackwell, 2015)
Formação inicial para o trabalho pedagógico com os anos iniciais do ensino fundamental: estudo do curso de Educação Física/Licenciatura/UFSM
(Universidade Federal de Santa MariaBREducação FísicaUFSMPrograma de Pós-Graduação em Educação Física, 2015-03-09)
This study aimed to investigate how to configure the initial formation in Physical
Education/Bachelor of UFSM for pedagogical work at the first years of Elementary School.
To do so, it was used the documentary analysis ...
Correlates of blood pressure according to early, on time, and late maturation in adolescents
(Wiley-Blackwell, 2015-09-26)
The aim of this study was to estimate the prevalence and correlates of blood pressure (BP) according to somatic maturation in Southern Brazilian adolescents. A total of 1321 adolescents participated in the study (732 girls), ...
