Oxidative catalytic removal of hydrocarbons over Pt/Al2O3 catalysts
(Elsevier Science, 2000-12)
The reaction kinetics, structure sensitivity, and in situ activation of cyclopentane and methane combustions were studied on Pt/Al2O3 catalysts of different platinum and chlorine loadings. The catalyst activities were ...
Thermal stability test of UO2-doped pellet manufactured at INB
(Associa????o Brasileira de Energia Nuclear, 2018)
Comparison of Ni and Ni-Ce/Al2O3 catalysts in granulated and structured forms: Their possible use in the oxidative dehydrogenation of ethane reaction
(Elsevier, 2014-03)
Ni and Ni-Ce/Alumina catalysts in structured form were prepared, characterized by different techniques and tested in the oxidative dehydrogenation of ethane (ODE). In order to gain further insight into active species, ...
In vitro activity of zinc oxide-eugenol and glass ionomer cements on Candida albicans
(2005-04-01)
The aim of this study was to evaluate in vitro the antimicrobial activity of glass ionomer (GIC) and zinc oxide-eugenol (ZOE) cements against Candida albicans. Standardized GIC and ZOE specimens were maintained in contact ...

Characterization of oxidizing activity of a microbial community in an industrial bioleaching heap
(TRANS TECH PUBLICATIONS LTD, 2009)
In order to explore new options to optimize the low-grade copper ore bioleaching process, it is important to understand the kinetics of microbial oxidation at industrial level. This work studies the changes of iron and ...
Oxidative stress and altered steroidogenesis in the ovary by cholinergic stimulation of coeliac ganglion in the first proestrous in rats. Implication of nitric oxide
(Academic Press Inc Elsevier Science, 2016-02-29)
An ex-vivo Coeliac Ganglion-Superior Ovarian Nerve-Ovary (CG-SON-O) system from virgin rats in the first proestrous was used to test whether cholinergic stimulation of CG affects oxidative status and steroidogenesis in the ...
Effect of different radiopacifying agents on the physicochemical properties of white portland cement and white mineral trioxide aggregate
(2012-03-01)
Introduction: The aim of this study was to evaluate the pH, calcium ion release, setting time, and solubility of white mineral trioxide aggregate (WMTA) and white Portland cement (WPC) combined with the following radiopacifying ...
