Journal ArticleDOI
Satisfaction and continuous use intention of e-learning service in Brazilian public organizations
Fernando Antonio de Melo Pereira,Anatália Saraiva Martins Ramos,Maria Aparecida Gouvêa,Marconi Freitas da Costa +3 more
TL;DR: Investigation of the constructs of Technology Readiness Index (TRI) and the Decomposed Expectancy Disconfirmation Theory (DEDT) as determinants of satisfaction and continuous use intention in e-learning services applied in public organizations shows that quality, quality disconfirmation, value and value disconf confirmation positively impact on satisfaction.
Journal ArticleDOI

Gisela Silva,Helena Moreira Silva,Joao Nascimento,Jean-Pierre Gonçalves,Fernando Antonio de Melo Pereira,Rosa Lima +5 more
TL;DR: The aim of this study is to determine the local pattern of first‐line antimicrobials resistance and the eradication rate of Helicobacter pylori antimicrobial resistance, primarily for clarithromycin.
Journal ArticleDOI
Inorganic arsenic speciation by differential pulse anodic stripping voltammetry using thoria nanoparticles-carbon paste electrodes.
TL;DR: Two novel thoria (ThO2) nanoparticles-carbon paste electrodes were used to evaluate an anodic stripping voltammetric method for the direct determination of arsenite and total inorganic arsenic (arsenite plus arsenate) in water samples.
Journal ArticleDOI
Effect of temperature on the crystallinity, size and fluorescent properties of zirconia-based nanoparticles
TL;DR: In this paper, the same authors showed that the presence of arsenic and cysteine in the ZrO 2 nanoparticles facilitated the emission of fluorescence, even after thermal treatments at 873 K.
Journal ArticleDOI
Raman spectrometry as a screening tool for solvent-extracted azo dyes from polyester-based textile fibres
TL;DR: In this article, conventional Raman spectrometry was assessed as an analytical tool for identification of the azo function in the extracts of fibres obtained after applying a liquid-solvent extraction procedure to the polyester-based textile products.
