Assessment of the chemical composition in different dental implant types: An analysisthrough EDX system (2020)
(MDPI AG, 2020-09-14)
The use of dental implants has been increasing in the last years; however, their chemical composition is an important issue due to the fact that the implant surface may suffer a corrosion process, allowing the possibility ...
Socio-educational Implications of Creativity from Pedagogical Mediation: A critical review (2020)
(Universidad Austral de Chile, 2020)
The school continues to be a routine and normative space, notoriously neglecting socio-emotional, cultural, historical, and even political aspects of learning. We believe that the school must integrate educational alternatives ...
Diagnosis of psychosocial factors associated with fatigue in aeronautical sector (2020)
(Interciencia Association, 2020-07)
The purpose of this work was to assess psychosocial conditions of a group of cabin crew members and the status of fatigue and affection to which they could be exposed. The sample consisted on 464 Chilean aeronautical ...
Electron count and electronic structure of bare icosahedral Au32 and Au33 ionic nanoclusters and ligated derivatives. Stable models with intermediate superatomic shell fillings (2020)
(NLM (Medline), 2020-09-23)
DFT calculations were carried out on bare Au32 and Au33 nanoclusters with various charges, in order to analyze their stability with respect to different cluster electron numbers. Results indicate that in addition to the ...

Analysis of the Zonula occludens Toxin Found in the Genome of the Chilean Non-toxigenic Vibrio parahaemolyticus Strain PMC53.7 (2020)
(Frontiers Media S.A., 2020-09-24)
Vibrio parahaemolyticus non-toxigenic strains are responsible for about 10% of acute gastroenteritis associated with this species, suggesting they harbor unique virulence factors. Zonula occludens toxin (Zot), firstly ...
Utilization of industrial by-product fungal biomass from Aspergillus niger and Fusarium culmorum to obtain biosorbents for removal of pesticide and metal ions from aqueous solutions (2020)
(Elsevier Ltd, 2020-10)
In this work, Aspergillus niger and Fusarium culmorum cell wall by-products were chosen as microbial sources for chitin and chitosan production. Both polysaccharides were characterized by FTIR and 13C-CPMAS NMR, but GPC ...
Fluorescence turn-on and turn-off mechanisms of a dual-selective chemosensor of Bi3+ and pH changes: Insights from a theoretical perspective (2020)
(Elsevier Ltd, 2021-02)
The N-hydroxy 1,8-naphthalimide (LH) is an optical dual-selective chemosensor toward Bi3+ ions as well as pH changes. In specific, this senor is selective to Bi3+ ions, which turn-on the fluorescence upon their interaction; ...
Resolved observations at 31 GHz of spinning dust emissivity variations in ρ Oph (2020)
(Oxford University Press, 2020-05-14)
The ρ Oph molecular cloud is one of the best examples of spinning dust emission, first detected by the cosmic background imager (CBI). Here, we present 4.5 arcmin observations with CBI 2 that confirm 31 GHz emission from ...
