(Universidad de Chile, 2022)El derecho a la participación de los niños, niñas y adolescentes en los procesos que afectan sus vidas exige que su intervención sea significativa. Esto implica que no basta solo con escuchar a los niños, niñas y ...
-
(Elsevier, 2016)Iodine enrichment in the Atacama Desert of northern Chile is widespread and varies significantly between reservoirs, including nitrate-rich "caliche" soils, supergene Cu deposits and marine sedimentary rocks. Recent studies ...
-
(SPRINGER, 2009-08)Recent studies have suggested the involvement of highly saline deep formation waters that modified preexisting Cu assemblages to form atacamite during supergene oxidation of Cu deposits in the Atacama region. In this report, ...
-
(Blackwell, 2006)We consider a fast solar wind-type plasma consisting of electrons, a protons background, and a much more tenuous alpha particle beam. It is shown that such system is unstable against ion acoustic-like waves triggered by ...
-
(EDP Sciences, 2013)Context. Ionising stars reshape their original molecular cloud and impact star formation, leading to spectacular morphologies such as bipolar nebulae around Hii regions. Molecular clouds are structured in filaments where ...
-
(Universidad de Chile, 2012)Uno de los problemas claves en el estudio de la formación de estrellas es determinar si acaso el paradigma de formación de estrellas de baja masa, específicamente, contracción gravitacional y la posterior presencia de un ...
-
(Universidad de Chile, 2019)Existen problemas de ambigüedad en la estimación de los parámetros del plasma ionosférico entre los 130 y los 300 km en los Radares de Dispersión Incoherente (ISR). En esos rangos, el ISR es incapaz de distinguir entre ...
-
(Springer, 2016)The lithosphere and the atmosphere/ionosphere continuously exchange energy through various coupling mechanisms. In particular, the earth surface displacement caused by earthquakes, volcanoes and tsunamis can manifest as ...
-
IoT-RECSM—resource-constrained smart service migration framework for IoT edge computing environment (MDPI, 2020)The edge-based computing paradigm (ECP) becomes one of the most innovative modes of processing distributed Interneit of Things (IoT) sensor data. However, the edge nodes in ECP are usually resource-constrained. When more ...
-
(AGU Publications, 2015)The subduction zone in northern Chile is a well-identified seismic gap that last ruptured in 1877. On 1 April 2014, this region was struck by a large earthquake following a two week long series of foreshocks. This study ...
-
(American Astronomical Society, 2015)We present the results of continuum and 12CO(3–2) and CH3OH(7–6) line observations of IRAS 16547−4247 made with the Atacama Large Millimeter/submillimeter Array (ALMA) at an angular resolution of ∼0. 5. The 12CO(3–2) ...

(Frontiers Media S.A., 2019)The IRE1α/XBP1s signaling pathway is an arm of the unfolded protein response (UPR) that safeguards the fidelity of the cellular proteome during endoplasmic reticulum (ER) stress, and that has also emerged as a key regulator ...
-
(IEEE, 2022)Iris is one of the most accurate biometrics. This has led to the successful development of large-scale applications. However, with population growth, and new international applications, datasets are constantly increasing ...
-
(American Physiological Society, 2015)Recent evidence shows that iron induces the endocytosis of the iron transporter dimetal transporter 1 (DMT1) during intestinal absorption. We, and others, have proposed that iron-induced DMT1 internalization underlies the ...
-
(Royal Soc. Chemistry, 2021)Siderophores are iron-chelating compounds that aid iron uptake, one of the key strategies for microorganisms to carve out ecological niches in microbially diverse environments. Desferrioxamines are the principal siderophores ...
-
(2015)Train algebras were introduced by Etherington in 1939 as an algebraic framework for treating genetic problems. The aim of this paper is to study the representations and irreducible representations of power-associative ...
-
(EDP SCIENCES S A, 2008-03)Context. The recently-discovered lack of close binaries, among extreme horizontal branch (EHB) stars in Galactic globular clusters, has thus far constituted a major puzzle, in view of the fact that blue subdwarf stars – ...
-
(Wiley-Blackwell, 2018)© 2018 Society for Consumer Psychology Despite a recognition that consumers want to be cool and value cool brands, the literature has only just begun to delineate what makes things cool. Writing by scholars, quotes by ...
-
(Elsevier Inc., 2019)The bone marrow adipose tissue (BMAT) is a conserved component of the marrow microenvironment, providing storage and release of energy and stabilizing the marrow extent. Also, it is recognized both the amount and quality ...
