Complementaridade quântica nos processadores quânticos da IBM
(Universidade Federal de Santa Maria, 2023-01-31)
Bohr’s principle of complementarity, after gaining contributions from several researchers, moved from a qualitative analysis to a quantitative analysis through what we
call today complementarity relations (CR). This change ...
Fotometria CCD UBVRI de aglomerados de estrelas das Nuvens de Magalhães
(Universidade Federal de Santa Maria, 2006-05-19)
We present UBVRI CCD photometry in the Johnson-Cousins photometric system for a sample of twenty nine Magellanic Cloud star clusters (Lindsay 16, 26, 29, 48, 53, 61, 66, 67, 72, 76, 79, 82, 83, 85 of the Small Cloud ...
Deposição de nano-grãos de Co em uma matriz de CoO/Al2O3 por Magnetron Sputtering
(Universidade Federal de Santa Maria, 2007-10-20)
Granular magnetic systems can be composed by magnetic particles or clusters with size of some nanometers. These magnetic nanoparticles present different magnetic order phases, as superparamagnetic, and they can be embedded ...
Deposição de nano-camadas de VO2 por Magnetron Sputtering
(Universidade Federal de Santa Maria, 2007-04-13)
The vanadium dioxide (VO2) shows a metal-insulator transition (MIT) near the room temperature with huge changes in its electrical and optical behavior. Both the
electrical and optic properties, and even the transition ...
Estudo do parâmetro de ordem e do momento magnético em borocarbetos pseudoquaternários
(Universidade Federal de Santa Maria, 2007-03-27)
Experimental data show that the dissolved impurities of the Mn presents a magnetic moment when substitute the Ni atom in pseudoquaternary borocarbide Y (Ni(1−x)Mx)2B2C, this is not observed if the impurities are Fe and Co. ...
Nanotubos de carbono interagindo com selênio: uma simulação de primeiros princípios
(Universidade Federal de Santa Maria, 2009-01-15)
This work presents a theoretical study about the interaction between semiconducting carbon nanotubes (8,0) single-wall (SWNT), with selenium nanostructures by first principles calculations using the density functional ...
Escala temporal da turbulência para escoamento noturno acima da copa de uma floresta tropical úmida na Amazônia
(Universidade Federal de Santa Maria, 2008-09-12)
The LBA (Large Scale Biosphere-Atmosphere in Amazônia) project has been using
the eddy covariance technique since 1998 to continuously monitor the surface fluxes of
energy, water vapor and carbon over Amazônia. The results ...
Estudo das propriedades eletrônicas e estruturais em nanotubos de fosfeto de índio
(Universidade Federal de Santa Maria, 2009-09-29)
In this work, using first principles study based in framework of the density functional theory with the local density approximation (LDA) for the exchange-correlation
functional, we developed a detailed study about the ...
Estudo teórico da estabilidade e propriedades eletrônicas de defeitos em nanotubos de GaN
(Universidade Federal de Santa Maria, 2008-03-05)
The stability and electronic properties of antisities, vacancies and substitutional Si and C impurities in
GaN nanotubes are studied using spin-polarized density functional theory within the local density approximation
(LDA) ...
Ventos de gás ionizado a partir do núcleo da galáxia OH megamaser IRAS 09320+6134
(Universidade Federal de Santa Maria, 2023-03-03)
[Ultra]luminous infrared galaxies are extremely bright objects in this spectrum range, with luminosities bigger than 1011 L . It is observed that these objects, which typically consist of
interactions and mergers of ...
