Cinemática e distribuição do gás ionizado na região central das galáxias Seyfert NGC4501 e NGC3982
(Universidade Federal de Santa Maria, 2015-02-25)
We present two-dimensional (2D) maps for emission-line fluxes and ratios and kinematics for
the central regions of the Seyfert galaxies NGC 4501 and NGC 3982, from optical spectra obtained
with the GMOS (Gemini Multi ...
Magnetoimpedância em multicamadas de Ni81Fe19/Cu com a corrente de sonda perpendicular ao plano do filme
(Universidade Federal de Santa Maria, 2006-06-02)
In this work the behavior of the magnetoimpedance (MI) in ferromagnetic
multilayered (Ni81Fe19/Cu) produced by magnetron sputtering was studied. In all
measurements, the probe current was applied perpendicularly to the ...
Produção de filmes supercondutores de nióbio e de sistemas híbridos crescidos por Magnetron Sputtering DC
(Universidade Federal de Santa Maria, 2012-08-16)
Currently, several research groups have been devoted to the production of superconducting
films. This interest lies on the facility of their manipulation, on the understanding of basic
concepts of the superconductivity ...
Distribuição e manipulação de coerência quântica em sistemas multipartidos
(Universidade Federal de Santa Maria, 2017-02-24)
Repeatedly in the field of Quantum Information Science (QIS) it’s essentially required of
physical systems the quantification concerning its quantum phenomena, such as Quantum
Coherence (QC) relying in quantum superposition ...
Estudo do exchange bias em filmes finos de NiFe/FeMn (bicamadas) e NiFe/IrMn (multicamadas)
(Universidade Federal de Santa Maria, 2016-03-23)
The Exchange Bias (EB) phenomenon consists of an interfacial exchange coupling between a ferromagnetic (FM) material and an antiferromagnetic (AFM) one and has as the main characteristics the rise of a unidirectional ...
Caracterização de envelopes estendidos de luz em galáxias BCGS
(Universidade Federal de Santa Maria, 2022-08-26)
In this work, we revisit the problem of morphological classification of BCG galaxies, in order to identify the characteristic signatures of cD-class galaxies. For this, we analyze the r-band surface brightness distributions ...
Avaliação do método do balanço da camada limite para a estimativa de fluxos turbulentos noturnos
(Universidade Federal de Santa Maria, 2006-10-27)
This work is about to verify the performance of the boundary layer budgeting method as alternative for measuring the surface turbulent fluxes in conditions that allow the
validation of the measurements with data taken ...
Fluxos turbulentos de CO2 em uma área de arroz irrigado no RS
(Universidade Federal de Santa Maria, 2007-11-28)
This thesis quantifies the net change of CO2 (NEE) in an irrigated rice crop cultivation in
RS (Brazil). The research is part of the project CT-HIDRO, which presents as main purpose the
description of surface conditions ...
Modelagem lógica de senescência celular humana
(Universidade Federal de Santa Maria, 2012-12-12)
After the progressive telomere shortening in successive cell divisions, normal
somatic cells undergo a growth arrest called cellular senescence that occurs due to
incomplete DNA replication. Senescence can also be activated ...
Efeitos de flutuações quânticas em um modelo vidro de spin com cluster
(Universidade Federal de Santa Maria, 2019-05-29)
In this work we study the effects of quantum fluctuations in a disordered magnetic system.
We consider a cluster-spin Ising model with antiferromagnetic short range interactions (J0)
and disordered long range interactions ...
