Effect of MnTBAP on in vitro capacitation of frozen-thawed stallion sperm
(Elsevier, 2020-10)In vitro manipulation of spermatozoa leads to deleterious changes of structure and function that occur mainly due to oxidative stress, therefore, prevention or treatment is a strategy to improve the functions of processed ... -
Effect of nanosilver surfaces on peptide reactivity towards reactive oxygen species
(ROYAL SOC CHEMISTRY, 2018)The interaction of a terminal tryptophan residue within collagen mimetic peptides when tethered to nanometric silver surfaces was studied using a combination of steady state spectroscopy, ultrafast spectroscopy, and molecular ... -
Effect of phonons on the electron spin resonance absorption spectrum
(IOP Publishing Ltd., 2020-07)The unavoidable presence of vibrations in solid-state devices can drastically modify the expected electron spin resonance (ESR) absorption spectrum in magnetically active systems. In this work, we model the effect of phonons ... -
Effect of protection cut on the establishment of regeneration in Nothofagus forest
(INST ECOLOGIA A C, 2018)The objective of this project was to evaluate the effect of a cut, on the establishment of regeneration in a forest dominated by Nothofagus obliqua in the Andes Mountains of the Maule Region, after four years of its ... -
Effect of subsurface voids on the nanoindentation of Fe crystals
(IOP Publishing Ltd., 2020-03)Subsurface voids may strongly affect the response of materials to nanoindentation. We explore these effects for a bcc single-crystalline Fe sample using molecular dynamics simulation. Deformation occurs mainly by nucleation ... -
Effect of the atomic construction and preparation procedure on the deformation behaviour of CuZr metallic glasses
(TAYLOR & FRANCIS LTD, 2021-08-29)The construction of metallic glasses (MGs) at the atomic scale for molecular dynamics simulations involves several factors that ultimately affect the deformation behaviour, a matter that has been rarely addressed in the ... -
Effect of the Generation of PAMAM Dendrimers on the Stabilization of Gold Nanoparticles
(American Chemical Society, 2020-06-22)The behavior of small and intermediate generations of poly(amidoamine) (PAMAM) dendrimers and PAMAM vertical bar gold nanocomposites was studied by computational tools and experimental techniques. Molecular dynamics ... -
Effect of the monomers ratio in the electrosynthesis of poly (aniline-co-o-methoxyaniline) on steel corrosion protection
(SOC CHILENA QUIMICA, 2020-12)In this work, the synthesis of poly(aniline-co-o-methoxyaniline) was carried out on AISI 304 steel, by voltammetric or potentiostatic method. Electropolymerization was achieved from different ratios of 0.4 mol.L-1 ... -

(Sociedad Chilena de Química, 2020-12)In this work, the synthesis of poly(aniline-co-o-methoxyaniline) was carried out on AISI 304 steel, by voltammetric or potentiostatic method. Electropolymerization was achieved from different ratios of 0.4 mol.L-1 ... -
Effect of Tip Roundness on the Nanoindentation of Fe Crystals
(Springer New York, 2020-04)Indentation tips are never atomically sharp, but rounded at their end. We use atomistic simulation to study the effect of tip roundness for the particular case of a cube-corner pyramidal indenter by comparing the results ... -
Effect of Type of Pregnancy on Transcriptional and Plasma Metabolic Response in Sheep and Its Further Effect on Progeny Lambs
(Chile. Universidad Mayor, 2020-12)Simple Summary: The present study was carried out in order to determine the effect of type of pregnancy on the mammary gland development, evaluated through the transcriptional expression of genes that are associated to ... -
Effect of warm-up on hand grip strength in sedentary overweight women
(Universidad Nacional de Colombia, 2020-11)Introduction: In recent years, handgrip strength assessment has gained special relevance in health. However, a standardized application protocol that includes warm-up procedures is required to measure it. Objective: To ... -
Effect of yeast (Xanthophyllomyces dendrorhous) and plant (Saint John's wort, lemon balm, and rosemary) extract based functional diets on antioxidant and immune status of Atlantic salmon (Salmo salar) subjected to crowding stress
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2018)Salmon farming may face stress due to the intensive culture conditions with negative impacts on overall performance. In this aspect, functional feed improves not only the basic nutritional requirements but also the health ... -
