Uma sistemática baseada no reuso de atividades para adaptação de processos de software utilizando linhas de processos de software
(Universidade Federal de Santa Maria, 2014-09-01)
Software process definition requires choosing the process elements that appropriately
fulfil the tailoring requirements, such as to prevent risks or to satisfy quality goals. The selection
of appropriate process elements ...
Avaliação de métodos de preparo de amostras para a determinação de halogênios em plantas medicinais
(Universidade Federal de Santa Maria, 2015-07-21)
In this work, four sample preparation methods were evaluated for further determination of halogens (F, Cl, Br e I) in medicinal plants. The evaluated sample preparation methods were microwave-induced combustion (MIC), ...
Rotâmeros de [2]rotaxanos: estudo do efeito do macrociclo sobre o eixo molecular
(Universidade Federal de Santa Maria, 2017-07-20)
This work presents the synthesis of three new threads and three new [2]rotaxanes models that have asymmetric stopprs, which allows rotamers to be obtained. The synthesis of the [2]rotaxanes was performed by clipping reaction, ...
Síntese de 1,4-diazaciclo-2-ilidenos N-pirrolil/furanil substituídos
