Produção de emaranhamento pela interação dipolar magnética
(Universidade Federal de Santa Maria, 2018-08-06)
In this work we consider a bipartite system consisting of magnetic dipoles, initially characterized by product-states uncorrelated until the dynamics of evolution is established by magnetic dipole interaction. We reproduce ...
Trocas de energia e massa no cultivo de soja e trigo no sul do Brasil
(Universidade Federal de Santa Maria, 2018-08-06)
Brazil is one of the largest agricultural producers in the world. With this, a vast area of
Brazilian territory is covered by crops that directly influence the annual carbon balance and
the exchange of water vapor between ...
Exchange bias em bicamadas de NiFe/FeMn: um estudo em função da espessura da camada antiferromagnética
(Universidade Federal de Santa Maria, 2018-12-04)
The exchange bias (EB) arises, generally, from the interfacial coupling between a ferromagnetic
layer (FM) and an antiferromagnetic layer (AFM). The most well-known manifestations
of this phenomenon, in samples with a ...
Estudo teórico de nanodomínios de grafeno e siliceno em carbeto de silício
(Universidade Federal de Santa Maria, 2018-02-20)
In this work the structural, optical and electronic properties of hexagonal monolayer compounds
of silicon carbide (h-SiC) in pristine form and in the presence of defects like graphene (h-
SiC-C) and silicene (h-SiC-Si) ...
Modelagem da interação superfície- atmosfera: calibração dos modelos sib2 e sib3 em uma área de pastagem no sul do Brasil
(Universidade Federal de Santa Maria, 2018-02-08)
The Simple Biosphere Model (SiB) modelwas developed to represent and estimate the interactions
between soil, vegetation and atmosphere, which describe the transfer processes of energy, mass
and momentum. In this sense, ...
Os primeiros 62 AGNS observados com o SDSS-IV MANGA: cinemática estelar e do gás
(Universidade Federal de Santa Maria, 2018-07-25)
Active galaxies exhibit a great luminosity in central region that can not be explained only by the
emission of the stars of the galaxy, but by the presence of an active galactic nucleus (AGN). In
this scenario, gravitational ...
Estudo teórico das propriedades mecânicas e eletrônicas de sistemas bidimensionais do grupo IV sob deformações
(Universidade Federal de Santa Maria, 2018-08-02)
In this work we study two dimensional materials compounds of group IV elements such as
graphene, silicene and germanene under biaxial and uniaxial strain. The aim of this study is
understand the mechanical properties of ...
Cinemática e excitação do gás em galáxias com emissão megamaser de OH
(Universidade Federal de Santa Maria, 2018-06-29)
We present a multiwavelength study of galaxies that host OH Megamaser emission. We
used integral field unit spectroscopic data obtained with the GMOS-IFU instrument, radio
data obtained with VLA and HST data for ...
Formação estelar e emissão de poeira em núcleos ativos de galáxias
(Universidade Federal de Santa Maria, 2018-12-20)
The energy coming from Active Nuclei of Galaxies (AGN) is attributed to the process of
accretion of matter to a central Supermassive Black Hole (SMBH). The gases that flow towards
the center of the galaxies (inflows of ...
Estudo da molhabilidade e superrepelência em duas dimensões usando modelo de Potts
(Universidade Federal de Santa Maria, 2018-07-20)
Our study to investigate the wettability of flat and structured surfaces in pillars based on
two- dimensional simulations, using the Potts cellular model (CPM). We can find a
superhydropic character on the surface when ...
