Oxidação de CO sobre catalisadores de Co e/ou Mn modificados com Mo e suportados em SBA-15 – Efeito do método de preparação e da presença de vapor de água e dióxido de enxofre na atividade catalítica
(Universidade Federal de São Carlos, 2016-08-25)
The increasing demand for oil and oil derived products contributed to the alarming increase in the gaseous pollutants emissions in general and mainly contributed to the increase in carbon monoxide (CO) emissions in the ...
Estudo do metabolismo de Salmonella typhimurium : da abordagem tradicional à análise dos fluxos metabólicos
(Universidade Federal de São Carlos, 2015-08-27)
The genus Salmonella spp. has been extensively investigated because these
bacteria are important pathogens that frequently cause severe diseases and gastrointestinal
infections in humans and animals. Moreover, in recent ...
Otimização descentralizada coordenada aliada a estratégias de controle plantwide para o controle de processos químicos
(Universidade Federal de São Carlos, 2016-07-08)
Chemical plants are increasingly complex and integrated with recycle streams promoting
energy integration and increasing process yield. This results in a complex dynamic
behavior which can interfer in control systems ...
Análise da secagem convectiva de folhas de manjericão (Ocimum basilicum L.)
(Universidade Federal de São Carlos, 2013-03-19)
Convective drying of leaves involves heat and mass transfer in packed-beds of deformable material, since the leaves shrink significantly when the moisture is removed. Therefore, the packing structure changes over time, and ...

Avaliação de parâmetros globais de desempenho de biorreatores pneumáticos através de fluidodinâmica computacional
(Universidade Federal de São Carlos, 2015-03-25)
Pneumatic bioreactors are devices free of moving parts which have the purpose
of converting raw materials in bio-products of commercial interest by the action of enzymes
or cells. They are promising in the biochemical ...
Produção de etanol 2G a partir de hemicelulose de bagaço de cana-de-açúcar utilizando Saccharomyces cerevisiae selvagem e geneticamente modificada imobilizadas
(Universidade Federal de São Carlos, 2017-03-30)
In ethanol production process from hemicellulosic fraction, the use of xylooligomers (XOS)
as substrate reduce the contamination risk, favoring its application at industrial scale. Thus, a
biocatalyst, containing xylanases, ...
