El objetivo del trabajo fue determinar el % de Aporte Dietario Recomendado (ADR) de fluoruro ioduro y cloruro, cubierto por la ingesta de 2 mateadas completas de 50 g. de yerba mate y 500 mL. de agua c/u. Se utilizaron 38 ...
Chemical composition and biological prospects of essential oils and extracts of aphyllocladus spartioides growing in northwest Argentina
(Wiley, 2017-03-29)
Aphyllocladus spartioides WEDD. is a native and aromatic herb used in traditional medicine, however it is still poorly investigated. In this work, the volatile profile of A. spartioides growing in Hornillos-Northwest ...
Evaluation of the influence of texture and microstructure of titanium substrates on TiO2 anodic coatings at 60 V
(Elsevier, 2017-09-01)
The current paper analyzes the influence of texture and microstructure of Ti substrates on morphology and color of titanium dioxide coatings obtained by anodic oxidation. Substrates of Ti grade 2 and Ti grade 5 with different ...
Influence of the electrolyte concentration on the smooth TiO2 anodic coatings on Ti-6Al-4V
(MDPI, 2017-03-03)
To obtain smooth TiO2 coatings for building a new design of Ti-6Al-4V heart valve, the anodic oxidation technique in pre-spark conditions was evaluated. TiO2 coating is necessary for its recognized biocompatibility and ...
Genetic algorithm applied to parameter estimation of bacterial growth modeling
(Elsevier, 2016-11-14)
Predictive microbiology is nowadays one of the main tools to understand microbial interactions and to assess the quantitative risk in foods. Several models have been developed in order to predict microorganism growth. The ...
Comparison among growth model of interacting microorganism : a lactic acid bacteria and Listeria monocytogenes
(Elsevier, 2017-10-30)
Predictive food microbiology is normally based on mathematical models to predict the growth, inactivation or probability of microorganism growth which can be applied to establish the shelf-life of food. At present the ...
Production and characterization of TiO2 nanofilms for hemocompatible and photocatalytic applications
(Springer, 2017-08-10)
Titanium dioxide (TiO2) coatings are currently produced for hemocompatible and photocatalytic applications by using two techniques: sol–gel and anodic oxidation. In this review, the research advances on TiO2 nanofilms ...
