WGS activity of a novel Cu-ZrO2 catalyst prepared by a reflux method. Comparison with a conventional impregnation method
(2013)
The activity in the WGS reaction of Cu/ZrO2 catalysts prepared by a method of refluxing in an aqueous NH4OH solution is studied. It is shown that at 3% Cu load the methods of impregnation over monoclinic or tetragonal ZrO2 ...
The T2 chart with mixed samples to control bivariate autocorrelated processes
(2016-06-02)
In this paper, we propose the use of the T2 chart with the mixed sampling strategy (MS) to monitor the mean vector of bivariate processes with observations that fit to a first-order vector autoregressive model. With the ...
Redes y proyectos migratorios de los senegaleses en Argentina
(Universidade de São Paulo. Faculdade de Filosofia, Letras e Ciências Humanas, 2015-12)
Este trabajo está centrado en la migración senegalesa hacia Argentina. A partir de un abordaje etnográfico analizaremos este colectivo migratorio para dar cuenta de su heterogeneidad, describiendo la conformación y ...
Transcriptional Profile of Diuron-Induced Toxicity on the Urinary Bladder of Male Wistar Rats to Inform Mode of Action
(Oxford University Press, 2011-08-01)
Diuron (3-(3,4-dichlorophenyl)-1,1-dimethylurea) is a substituted urea herbicide that induces rat urinary bladder urothelial tumors at high dietary levels (2500 ppm). The specific mode of action and molecular alterations ...
Pre-stimulus EEG oscillations correlate with perceptual alternation of speech forms
(CIENCIAS, 2016)
Speech perception is often seen as a passive process guided by physical stimulus properties. However, ongoing brain dynamics could influence the subsequent perceptual organization of the speech, to an as yet unknown extent. ...
Influence of the procurement site on physical and mechanical properties of cupiúba wood species
(2018-01-01)
Studies that estimate technological properties of tropical wood species (especially those from the Amazon Rainforest) for their use in building construction, mainly structures, are very desirable. This paper aimed to ...
Influence of provenance on physical and mechanical properties of Angelim-pedra (Hymenolobium petraeum Ducke.) wood species
(2021-01-01)
This research aims to investigate, with the aid of the Brazilian standard NBR 7190, analysis of variance (ANOVA—5% significance) and the regrouping bootstrap technique, the influence of the provenance regions Bonfim, Mucajaí ...
