Efeitos de frustração geométrica em antiferromagnetos desordenados com clusters
(Universidade Federal de Santa Maria, 2019-01-11)
In magnetic systems, frustration - which refers to the inhability to satisfy all the interactios
simultaneously - has ravealed a rich phenomenology. In particular, disorder and geometrical
features are possible sources ...
Modelo lógico da sinergia entre sinalização TGF_ e dano ao DNA no destino celular
(Universidade Federal de Santa Maria, 2017-08-29)
Many factors may cause damages to the DNA, among them we can quote environmental
pollution, ionizing radiations, amongst others. The signalization involved after an instituted
damage consists in activation pathways and/or ...
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 ...
Efeitos de campos magnéticos aleatórios em sistemas de vidro de spin com clusters
(Universidade Federal de Santa Maria, 2019-03-08)
This work investigates the effects of the presence of random magnetic fields (RFs) in
thermodynamic quantities that characterize the spin glass state (VS). We adopt a cluster
spin model that considers long-range disordered ...
Variabilidade horizontal de pequena escala e a influência de obstruções no escoamento de submeso na camada limite noturna
(Universidade Federal de Santa Maria, 2016-09-30)
The forcings responsible for the spatial variability of mean and turbulent quantities in the nocturnal boundary layer are not well understood, especially when the layer is in a very stable, highly stratified state. Mixing ...
Estudo do desalinhamento entre os eixos de anisotropia via magnetorresistência anisotrópica em sistemas com exchange bias
(Universidade Federal de Santa Maria, 2019-11-28)
The Exchange Bias effect (EB) arises in systems with interfacial coupling, generally between
a ferromagnetic (FM) and a antiferromagnetic (AFM) material. The well-known manifestations
of this phenomenon are the field ...
Efeitos da hibridização no pseudogap em um modelo de Hubbard d-p
(Universidade Federal de Santa Maria, 2019-08-30)
In this paper, we investigate the effects of hybridization with different symmetries on
the normal and superconducting properties of a Hubbard d-p model. The Hubbard d-p model
is a variation of the model proposed by ...
Estimativas da radiação de onda longa incidente na Região de Pampa Gaúcho
(Universidade Federal de Santa Maria, 2017-12-20)
The incident long wave radiation flux (L ↓) is a parameter that directly influences the
radiation balance on the surface. Measures of this variable are scarce, where the use of
classical equations may be an alternative ...
Estudo experimental de recursos quânticos usando os computadores quânticos da IBM
(Universidade Federal de Santa Maria, 2021-02-26)
Bell-diagonal states are extremely important for understanding the dynamics and applications
of some quantum resources. Quantum properties such as steering, entanglement,
and coherence, among others, can be used as ...
