Variações espaciais de propriedades físicas do remanescente de supernova RCW 103
(Universidade Federal de Santa Maria, 2008-06-19)
Since the observation of the supernova event SN 1987A, observational research on supernova and supernova remnants, including the ones on the optical spectrum,
has been much explored. However, most of these studies have ...
Estudo do ciclo diário da camada limite planetária através da simulação dos grandes turbilhões
(Universidade Federal de Santa Maria, 2008-12-15)
The PBL is the region on the troposphere characterized by existence of turbulence (BUSINGER, 1981). Turbulent flow is that when the fluctuations of the variables that describe the flow are amplified in time and space ...
Modelagem lagrangeana aplicada à dispersão de contaminantes em diferentes condições de estabilidade atmosférica
(Universidade Federal de Santa Maria, 2008-04-25)
In this dissertation, it was estimated contaminants concentration in different stability conditions of the Planetary Boundary Layer. In order to do this, it was used the Lagrangian stochastic model. The experiments by ...
Nanotubos de carbono interagindo com vitaminaS B3 e C: um estudo de primeiros princípios
(Universidade Federal de Santa Maria, 2008-03-18)
This work presents a theoretical study about the interaction between pristine or functionalized B3 and C vitamins with semiconducting carbon nanotubes (8,0) through first principles simulations. We evaluate the structural ...
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 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) ...
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 ...
