(Universidad Católica de Uruguay, 2020-06)
The Item Response Theory (IRT) is a set of psychometric models used in the development, assessment, improvement, and scoring of evaluating scales. This pedagogical article provides an initial overview of how to conduct, ...
Numerical simulation and experimental validation of a multi-step deep drawing process
(Springer-Verlag France, 2017-03)
This paper presents the numerical simulation of an industrial multi-step deep drawing process. A large strain finite element formulation including a hyperelastic elastoplastic constitutive model and a contact-friction law ...
Abrasion resistance of ductile iron austempered by the two-step process
(Elsevier Science SA, 2008-06)
The present work focuses in the study of the effect that a new two-step austempering heat treatment process, developed by Putatunda, has on the mechanical properties with emphasis on the response to the abrasive wear. A ...

Multitasking polyamine/ferrioxalate nano-sized assemblies: thermo-, photo-, and redox-responsive soft materials made easy
(Royal Society of Chemistry, 2019-11)
Responsive nanomaterials have emerged as key components in materials sciences. Herein, we report the one-step preparation of multi-stimuli responsive polyamine-salt aggregates (PSA) by ionically crosslinking polyethylenimine ...
Two-step production of anti-inflammatory soluble factor by Lactobacillus reuteri CRL 1098
(Public Library of Science, 2018-07)
We have demonstrated previously that a soluble factor (LrS) produced by Lactobacillus (L.) reuteri CRL 1098 modulates the inflammatory response triggered by lipopolysaccharide. In this study, the production of LrS by L. ...

Targeting glioblastoma stem cells: The first step of photodynamic therapy
(Elsevier Science, 2021-12)
Glioblastoma is one of the most malignant types of brain cancer. Evidence suggests that within gliomas there is a small subpopulation of cells with the capacity for self-renewal, called glioma stem cells. These cells could ...
Multiple response optimization of a QuEChERS extraction and HPLC analysis of diclazuril, nicarbazin and lasalocid in chicken liver
(Elsevier, 2020-05)
A method for the simultaneous determination of three commonly used coccidiostats in chicken liver was developed, comprising a multi-residue QuEChERS (quick, easy, cheap, effective, rugged and safe) extraction step, and a ...
