Uma classe de problemas de Dirichlet do tipo p(x)-laplaciano
(Universidade Federal de Santa Maria, 2019-04-11)
We study the following class of PDEs of 𝑝�(𝑥�)-laplacian type
﹛−div (︂𝜑�(𝑥�, |∇𝑢�|)∇𝑢�)︂ = 𝜆�𝑓�(𝑥�, 𝑢�), if 𝑥� ∈ Ω
𝑢�(𝑥�) = 0, if 𝑥� ∈ 𝜕�Ω,
where Ω ⊂ R𝑁� is a bounded domain with a Lipschitz boundary ...
Determinação de micotoxinas por UPLC-MS/MS em grãos armazenados sob condições de temperatura e atmosfera controlada
(Universidade Federal de Santa Maria, 2019-02-28)
This work aimed to develop and validate analytical methods for the determination of mycotoxins in beans, corn and soybean using UPLC-MS/MS and to evaluate the occurrence of mycotoxins in samples of these grains after six ...

Determinação simultânea de ferro e níquel em suplementos alimentares por HR-CS SS-GF AAS
(Universidade Federal de Santa Maria, 2019-02-26)
In this work a method was developed for the simultaneous determination of Fe and Ni as contaminants in dietary supplements by high-resolution continuum source graphite furnace atomic absorption spectrometry and direct solid ...
Estudo de compostos voláteis de níquel e vanádio em cimento asfáltico de petróleo virgem e envelhecido
(Universidade Federal de Santa Maria, 2019-03-22)
Among the heteroatoms present in petroleum, nickel and vanadium are the most abundant metals. Thus, these can be found in large quantities in petroleum derivatives, such as Asphaltic Petroleum Cement (APC). The presence ...
Um arcabouço ferramental para implantação personalizável de serviços de rede virtualizados
(Universidade Federal de Santa Maria, 2019-01-18)
The current telecommunication infrastructures rely on the use of network functions implemented
in dedicated hardware which are able to identify, handle, modify, and execute many
protocols and services. However, difficulties ...
Um roteiro para criação de conteúdo digital baseado na metodologia de resolução de problemas
(Universidade Federal de Santa Maria, 2019-03-20)
The process of teaching and learning mathematics is surrounded by several difficulties that, if not overcome, end up accumulating knowledge gaps. These gaps in turn amplify the difficulties and end up harming the learning ...

Extensões de Hopf-Ore e a décima conjectura de Kaplansky
(Universidade Federal de Santa Maria, 2019-06-28)
In this work we will treat, in particular, of the Hopf algebras and Hopf-Ore extensions.
One of ours main goals is to prove a theorem that characterizes when a Hopf algebra R
is a extension of Hopf-Ore of a Hopf algebra ...
Ray tracing em tempo real usando hierarchical scene signed distance fields
(Universidade Federal de Santa Maria, 2019-03-25)
Ray tracing is an important technique for obtaining photo-realistic images. The basic algorithm
is well known and consists of tracing rays from a synthetic camera position by
calculating the color of objects colliding ...
