A solução fundamental na obtenção das frequências naturais e autofunções de um sistema de viga dupla Euler-Bernoulli com camada elástica e força axial
(Universidade Federal de Santa Maria, 2022-08-18)
In this work we approach a double Euler-Bernoulli beam system with axial force coupled by
an elastic layer. We performed a matrix formulation for the system of equations and for the
boundary conditions, which allows ...

Síntese, estrutura cristalina e molecular de complexos nos sistemas 1,3-bis(p-azofenil)triazenido e 3-(2-flúorofenil)-1-(4-nitrofenil)triazenido/Pd(II)
(Universidade Federal de Santa Maria, 2002-08-05)
The reaction between palladium chloride and 1,3-bis(pazophenyl)triazenido/pyridine yields the complex trans-bis[1,3-bis(pazophenyl)triazenido]-bis(pyridine)palladium(II), complex (a), which
crystallizes in the triclinic ...
Ferro-processos aplicados à degradação de efluente da produção de trifluralina
(Universidade Federal de Santa Maria, 2002-08-02)
In this work, comparative studies about the performance of iron-processes were
carried out in the pre-treatment of effluent streams samples (under high
concentration) from the trifluralin herbicide production (amination ...
Modelos epidemiológicos em tempo discreto
(Universidade Federal de Santa Maria, 2022-08-25)
In an endemics, an infeccious disease remains prevalent, in low levels, in a population. In this
work, three discrete time mathematical models for an endemic disease are studied: the SIR,
the SEIR and SEIRS models. For ...
Síntese de eninos e enediinos por acoplamento de acetilenos terminais com dicloretos de diorganoil telúrio (IV)
(Universidade Federal de Santa Maria, 2003-02)
In this work, we have developed an efficient method to prepare enynes and
enediynes, by cross-coupling reaction of diorganyl tellurium (IV) dichlorides and
terminal alkynes. [...]
