A emissão do gás da região de linhas estreitas em galáxias Seyfert próximas
(Universidade Federal de Santa Maria, 2017-12-21)
The Active Galactic Nuclei (AGNs) show high luminosities ( 109 L ) and emit energy from
the accretion disk around the central Supermassive Black Hole (SMBH). The Narrow Line
Region (NLR) is the only AGN structure spatially ...
Abordagem para geração de processos de software consistentes
(Universidade Federal de Santa Maria, 2017-12-12)
Choosing the most appropriate components to compose a specific process for a project and ensuring the
consistency of this are not trivial tasks, requiring great knowledge and involvement of a process engineer. This
work ...
Obtenção e estudo da reatividade de ciano-acrilatos de etila e compostos relacionados com ênfase na síntese de N- e O-heterociclos
(Universidade Federal de Santa Maria, 2017-09-19)
This work reports the results of the reactivity study of the ethyl cyano-acrylates (3), obtained from the Horner-Wadsworth-Emmons (HWE) olefination reaction applied to α,β-unsaturated ketones (1) with diethyl (cyanomethy ...
Um framework para geração automática de sistemas multiprocessados reconfiguráveis heterogêneos
(Universidade Federal de Santa Maria, 2017-02-16)
Nowadays, embedded systems are getting more complex since functionalities are converging
to a single device, thus demanding for more processing capability. However, modeling
embedded processors is not a trivial task ...
Estimulador elétrico funcional com balanceamento ativo de cargas integrado em tecnologia CMOS de 130nm
(Universidade Federal de Santa Maria, 2017-09-11)
Functional electrical stimulation (FES) is a technique that has been used to restore
neurological functions. Successful examples of the use of FES include hearing and vision
recoveries in patients suffering from neurological ...
Determinação multirresíduo de agrotóxicos em milho empregando método QuEChERS modificado e LC-MS/MS
(Universidade Federal de Santa Maria, 2017-09-22)
Corn is a cereal used in human and animal food, and moreover, as a source of raw material for other by-products, acquiring global importance. By presenting a distinct centesimal composition when compared with others cereals, ...
Efeitos energéticos e topológicos no design de cocristais de compostos aromáticos e em 1,5-diaril-1h-pirazol-3-carboxilatos de etila
(Universidade Federal de Santa Maria, 2017-07-20)
This work presents the study of the supramolecular environment in multicomponent crystals. Multicomponent
crystals were defined by J. D. Dunitz as a crystal containing two or more components together, so that this
concept ...
Análise da influência ambiental sobre galáxias de núcleo ativo usando o levantamento MaNGA
(Universidade Federal de Santa Maria, 2017-07-04)
We examined the dependency between nuclear activity in galaxies and the environment in which they are located. Using data from the MaNGA survey from the Sloan Digital Sky Survey IV, we analyzed the gas kinematics of 62 ...
Determinação multirresíduo de agrotóxicos em abelha e pólen apícola empregando método QuEChERS modificado e LC-MS/MS
(Universidade Federal de Santa Maria, 2017-07-21)
The use of pesticides contributes to increase the production, but there is a growing concern with its adverse effects in the environment. The decline of bee population and the contamination of apicultural products by ...
Diagramas de fase do modelo de Ising definido sobre dois grafos acoplados
(Universidade Federal de Santa Maria, 2017-08-07)
In this work we study a model of two coupled complex networks, with the purpose to study
the phase diagrams and the metastability of the system. The networks have internal ferromagnetic
interactions and are coupled to ...
