Estudo teórico de compostos de C6F5-corrol funcionalizados com hidrocarbonetos aromáticos para aplicações em terapia fotodinâmica
(Universidade Federal de Santa Maria, 2021-09-06)
The oxygen singlet generation by molecules in photodynamic therapy (PDT) requires an
electronic excitation by light absorption within a specific wavelength window, and a subsequent
intersystem crossing transition to a ...
Velocidade do som em matéria quente e densa de quarks
(Universidade Federal de Santa Maria, 2022-04-25)
In this work two different approaches to the regularization of thermal integrals in the NJL
(Nambu–Jona-Lasinio) SU(2) model are investigated from the phenomenological point of
view. Showing the usefullness of the speed ...
Análise da origem da emissão e cinemática do gás na região central da galáxia NGC4546
(Universidade Federal de Santa Maria, 2020-03-11)
It is believed that most spheroidal galaxies host a Supermassive Black Hole (SMBH) at their centers and that, at some point, it becomes active, originating an Active Galaxy Nuclei (AGN). The formation and evolution of the ...
Caracterização de envelopes estendidos de luz em galáxias BCGS
(Universidade Federal de Santa Maria, 2022-08-26)
In this work, we revisit the problem of morphological classification of BCG galaxies, in order to identify the characteristic signatures of cD-class galaxies. For this, we analyze the r-band surface brightness distributions ...
Dinâmica da magnetização em filmes finos de Co20Fe60B20
(Universidade Federal de Santa Maria, 2021-02-28)
In this work, it was realize a ferromagnetic resonance insvestigation in Co20Fe60B20 thin films with diferent thickness between 100 - 2000 nm. The hysteresis curves were obtained with a vibrating sample magnetometer. The ...
Efeitos de interações de terceiros vizinhos sobre a criticalidade do modelo de Ising quântico na rede quadrada frustrada
(Universidade Federal de Santa Maria, 2023-02-14)
In the present work, we investigate the phase transitions of the Ising model with interactions
between first (J1), second (J2) and third (J3) neighbours in the square lattice with transverse magnetic field. In this study, ...
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 ...
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 ...
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 ...
Análise da anisotropia orbital de populações de galáxias em aglomerados
(Universidade Federal de Santa Maria, 2023-07-28)
In this work we analyze the velocity anisotropy profiles β(r) of the star-forming (SF), transition
(T), AGN, and quiescent (Q) galaxy populations belonging to gaussian clusters in
order to study the impact of a galaxy’s ...
