Sensibilidade do BRAMS para descrição de chuva e temperatura, no nordeste do Rio Grande do Sul, para diferentes resoluções espaciais
(Universidade Federal de Santa Maria, 2008-10-16)
This work presents a comparative study between precipitation and air temperature measurement
observed at a wether station, located in Veranópolis RS, with data obtained from
the BRAMS (Brazilian Regional Atmospheric ...
Estudo de primeiros princípios de defeitos nativos em monóxido de berílio
(Universidade Federal de Santa Maria, 2009-10-19)
The present thesis shows a study of native defects (vacancies and antisites) in
Beryllium Monoxide (BeO) by means of first principle calculations within Density
Functional Theory (DFT). We made use of Local Density ...
Algoritmo genético acoplado a um método multi-grid e a teoria dos grafos para determinação da estrutura de equilíbrio de aglomerados atômicos
(Universidade Federal de Santa Maria, 2012-12-14)
In this work we present a proposal to improve Genetic Algorithm method by coupling
it to the techniques of discretization of the configurational space via the multi-grid
methodology, and by employing a topological selection ...
Congelamento inverso em um modelo de vidro de spin fermiônico
(Universidade Federal de Santa Maria, 2012-10-03)
The present work studies the counterintuitive phenomenon of inverse transitions (IT). The
IT are a class of phase transitions (reversible) in which the ordered phase appears at higher
temperatures than the disordered ...
Estudo teórico da interação de flúor em nanoestruturas de BC2N
(Universidade Federal de Santa Maria, 2011-09-09)
In this work we perform a theoretical study about fluorine adsorption in BC2N
nanostructures. The fluorine interaction with the BC2N nanostructures was studied
using only atomic fluorine on two nanotubos with different ...
Sazonalidade da concentração de CO2 atmosférico em uma área agrícola no RS
(Universidade Federal de Santa Maria, 2012-01-31)
In this work an agricultural area in Cruz Alta/RS was used to evaluate the seasonality of CO2
concentration with respect to meteorological variables of temperature, global radiation and
rainfall. The study period was ...
Indução de um eixo fácil de magnetização utilizando máscaras de sombreamento em filmes finos de CoFeB
(Universidade Federal de Santa Maria, 2012-01-30)
CoFeB thin films were produced using the technique of magnetronsputtering. Six
samples were produced magnetic thin films with two different thicknesses, using
different settings for shading masks. For each film were made ...
Exchange bias perpendicular em multicamadas de IrMn/Co/Pd
(Universidade Federal de Santa Maria, 2023-04-26)
Magnetic skyrmions are spin textures that can arise in thin films that exhibit the Dzyaloshinskii–Moriya interaction. Such interaction emerges from symmetry breaking at the interface
between a ferromagnetic material and ...

Catálogo de intensidades de linhas de emissão de remanescentes de supernovas e aplicações
(Universidade Federal de Santa Maria, 2011-06-30)
Emission line intensities from ionized nebulae are an important information source about
this objects. There are many data on line intensities emitted from supernova remnants scattered
in the literature. However, these ...
