On the Secondary Instability of Forced and Unforced Laminar Separation Bubbles
(2015-01-01)
Previous studies demonstrate that the primary instability of laminar separation bubbles (LSB) on a flat-plate in the absence of external forcing is a three-dimensional centrifugal one. This work develops a weakly non-linear ...
Tratamiento fisioterapéutico en inestabilidad clínica de la columna cervical superior
(2018-08-20)
La inestabilidad de la columna cervical es una de las causas más frecuentes de dolor que se presenta en la actualidad en relación de la columna vertebral. El raquis craneovertebral es el responsable de la orientación de ...

Linear kinetic waves in plasmas described by Kappa Distributions
(Elsevier, 2017)
In this chapter we present an overview of the excitation, propagation, and
absorption of linear plasma waves in collisionless, spatially uniform, multicomponent,
magnetized non-Maxwellian plasma characterized by a ...
A firehose-like aperiodic instability of counter-beaming electron plasmas
(IOP Publishing, 2020)
Depending on the physical conditions involved, beam plasma systems may reveal new unstable regimes triggered by wave instabilities of different natures. We show through linear theory and numerical simulations the existence ...
Self-excited primary and secondary instability of laminar separation bubbles
(2020-01-01)
The self-excited instabilities acting on laminar separation bubbles in the absence of external forcing are studied by means of linear stability analysis and direct numerical simulation. Previous studies demonstrated the ...
On thermal instabilities in a viscoelastic fluid
(International Journal of Non-Linear Mechanics, 2006-01)
Effect of a large-amplitude circularly polarized wave on linear beam-plasma electromagnetic instabilities
(Blackwell Publishing Ltd, 2003)
In a previous paper, sufficiently large-amplitude and left-handed ‘‘pump waves’’
propagating parallel to the background magnetic field were shown to stabilize a
moderately dense beam in a proton plasma against the ...
Using telomeric chromosomal aberrations to evaluate clastogen-induced genomic instability in mammalian cells
(Springer, 2020-12)
Telomeres, the specialized nucleoproteic complexes localized at the physical ends of linear eukaryotic chromosomes, play a fundamental role in maintaining chromosomal stability and integrity, being one of the leading ...
KINETIC EFFECTS ON THE PARAMETRIC DECAYS OF CIRCULARLY POLARIZED ELECTROMAGNETIC WAVES IN AN ELECTRON-POSITRON PLASMA
(AMERICAN INSTITUTE OF PHYSICS, 2001)
Parametric decays of a circularly polarized wave in an electron–positron plasma, including relativistic effects on the particle motion in the wave field, are studied. The analysis is based on the Vlasov equation in order ...
