A distribuição e cinemática do gás em Mrk 766 vistas em detalhes a partir de observações no infravermelho
(Universidade Federal de Santa Maria, 2013-02-22)
We have mapped emission-line flux distributions and ratios as well as the gaseous kinematics
of the inner 450 pc radius of the Seyfert galaxy Mrk 766 using integral field near-IR J- and
Kl-band spectra obtained with the ...
Análise da anisotropia orbital de populações de galáxias em aglomerados
(Universidade Federal de Santa Maria, 2023-07-28)
In this work we analyze the velocity anisotropy profiles β(r) of the star-forming (SF), transition
(T), AGN, and quiescent (Q) galaxy populations belonging to gaussian clusters in
order to study the impact of a galaxy’s ...
Método de baixo custo para reutilização de máscaras N95 através de recarga eletrostática
(Universidade Federal de Santa Maria, 2023-07-28)
Due to the Covid-19 pandemic, a disease caused by the Sars-CoV-2 virus, the
use of personal protective masks has increased dramatically. The World Health
Organization (WHO) recommends the PFF2 model, equivalent to the ...
O áxion em condições extremas: matéria de quarks quente e magnetizada, meios densos e estrelas compactas
(Universidade Federal de Santa Maria, 2023-07-31)
We investigate the phase diagram of quantum chromodynamics by means of the Nambu-
Jona-Lasinio effective model, including the axion - a particle which emerges as a solution
of the strong charge-parity (CP) problem and ...
Termodinâmica e transições de fase existentes na matéria de quarks com desbalanceamento quiral
(Universidade Federal de Santa Maria, 2023-07-01)
In this dissertation, we have used effective models, such as the Nambu-Jona-Lasinio (NJL)
and the Polyakov–Nambu–Jona-Lasinio (PNJL) to describe and study the Quantum Chromodynamics (QCD) phase diagram with chiral imbalance. ...
Efeitos do momento magnético anômalo na matéria de quarks
(Universidade Federal de Santa Maria, 2023-07-28)
This work aims to investigate the effect of anomalous magnetic moment (AMM) of quarks in
the NJL and PNJL two-flavor models at finite temperature, chemical potential, and magnetic
field. To achieve this, we employed the ...
Simulação de canais quânticos usando preparação variacional de estados
(Universidade Federal de Santa Maria, 2023-10-13)
Quantum computers still suffer from errors that keep them in the category of Noisy
Intermediate-Scale Quantum (NISQ) computers. Among the various tools capable of
circumventing some of the problems of NISQ computers, ...
Comportamento eletrostático em interface líquido-sólido: estratégias para detecção de fluxo de líquidos
(Universidade Federal de Santa Maria, 2024-02-19)
Although known since ancient times, triboelectricity is a phenomenon whose fundamental
causes are not yet fully understood, especially in liquid-solid interfaces. Significant
efforts have initiated studies on electrostatic ...
Comportamento magnético e efeito magnetocalórico de nanoestruturas frustradas de Ising
(Universidade Federal de Santa Maria, 2024-02-20)
In this work, we investigate the magnetic and magnetocaloric properties of two frustrated
Ising clusters in the presence of a longitudinal magnetic field: the centered tetrakis hexahedron
structure and the hexagonal ...
Modelagem discreta de transição epitelial mesenquimal: o papel da matriz extracelular
(Universidade Federal de Santa Maria, 2024-04-09)
The epithelial-mesenchymal transition (EMT) is a biological process in which epithelial cells
undergo biochemical changes and are transformed into mesenchymal cells, a transition that
plays a crucial role in tumor ...
