Avaliação do "magnetron sputtering" como técnica para obtenção de MgB2
(Universidade Federal de Santa Maria, 2014-08-26)
In this work a survey of the potentialities and limitations of magnetron sputtering as a
tool for the production of MgB2 superconductors thin films has been made. Instead of the usual
approaches, like co-deposition onto ...
Simulação de algoritmos quânticos considerando a teoria quântica modal em Haskell
(Universidade Federal de Santa Maria, 2014-08-29)
The development of quantum algorithms faces some difficulties such as the lack of a
general-purpose quantum computer, a language or a specific formalism, or high consumption
of computational resources when it is simulation ...
Micotoxinas em matrizes de milho e trigo: validação de método analítico por ULPC-MS/MS e monitoramento em diferentes pontos da cadeia produtiva e comercial
(Universidade Federal de Santa Maria, 2014-02-24)
This study aims to validate an analytical multi-mycotoxin method using UPLC-MS/MS for 12 mycotoxins determination in wheat and maize matrices. The parameters evaluated for the validation were: calibration curve and linearity, ...
