Testing Newtonian gravity with distant globular clusters: NGC 1851 and NGC 1904
(2011)
Context. Globular clusters are useful for testing the validity of Newtonian dynamics in the low acceleration regime typical of galaxies, without the complications of non-baryonic dark matter. In the absence of disturbing ...
Ondas gravitacionais em regime pós Newtoniano
(Universidade Estadual Paulista (Unesp), 2022-03-07)
Gravitational waves are one of the most important results predicted by General Relativity. As their name suggests, they are ripples - or perturbations - in the geometry of spacetime. However, these disturbances are small, ...

Ultracold neutrons in the low curvature limit: Remarks on the post-Newtonian effects
(2024)
Ultracold neutrons are great experimental tools to explore the gravitational interaction in the regime of quantized states. From a theoretical perspective, starting from a Dirac equation in curved spacetime, we applied a ...
Um panorama sobre roll waves em escoamentos laminares e turbulentos com superfície livre
(Universidade Estadual Paulista (Unesp), 2007-12-07)
Os escoamentos na superfície livre que se processam sobre forte declividade podem desenvolver instabilidades ao cabo de tempo finito. Tais instabilidades aparecem sob formas de ondas tipo “hydraulic jumps” bem espaçados e ...

Modeling of non-Fickian diffusion and dissolution from a thin polymeric coating: An application to drug-eluting stents
(2018-04-20)
In this paper, we present a general model for non-Fickian diffusion and drug dissolution from a controlled drug delivery device coated with a thin polymeric layer. First, we study the stability and deduce an analytic ...
Visualization of viscoplastic fluid flow in an abrupt contraction using particle image velocimetry
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Mecânica e de MateriaisUTFPR, 2019-11-22)
The viscoplastic fluid flow of Carbopol solutions is investigated in the following experimental study, for laminar and turbulent regime through an abrupt contraction with an aspect ratio of β = 1:85. The pressure drop ...
