(Universidad Austral de Chile, 2019)This article aims at revealing the state of the art of inclusivity in the Chilean urban-housing sphere, as well as suggesting its relevance for the construction of fairer cities. For such purpose, the methodological strategy ...
-
(Springer New York LLC, 2019)Synthesis of CeO2, ZnO, and CeO2 nanocubes decorated on the surface of ZnO ovals via a simple hydrothermal method was investigated. The crystalline nature and purity of CeO2, ZnO and CeO2 decorated ZnO were confirmed through ...
-
(Springer Netherlands, 2019)Reinforcing bars removed from structural walls that belonged to a damaged building during the 2010 earthquake in Chile are studied under low-cycle fatigue testing. Damage of such walls was characterized by concrete crushing ...
-
(NLM (Medline), 2019)BACKGROUND: The primary cilium is a singular cellular structure that extends from the surface of many cell types and plays crucial roles in vertebrate development, including that of the heart. Whereas ciliated cells have ...
-
(Academic Press, 2019)Growth differentiation factor 11 (GDF11) is a novel factor with controversial effects on cardiac hypertrophy both in vivo and in vitro. Although recent evidence has corroborated that GDF11 prevents the development of cardiac ...
-
(Pontificia Universidad Catolica de Chile, 2019)Two experiments analyzed the role of extinction cues (EC) and stimuli associated to them in the reacquisition of conditioned ethanol tolerance. Ethanol-induced ataxia was measured in 80 rat subjects using a tilting plane, ...
-
(Nature Publishing Group, 2019)Mitochondria-associated membranes (MAMs) are central microdomains that fine-tune bioenergetics by the local transfer of calcium from the endoplasmic reticulum to the mitochondrial matrix. Here, we report an unexpected ...
-
(Pontificia Universidad Catolica de Chile, 2019)This study was aimed at analyzing, based on the participating teachers' emotional experience, the meanings constructed by them regarding the task of responding to diversity. To do this, the researchers analyzed 12 interviews ...
-
(Routledge, 2019)This article is concerned with the influences that are brought to bear on the design of school buildings and the effects that the design of these buildings have on those who teach and learn in them. The article also focuses ...
-
(Elsevier Ltd, 2019)Objective: The aim of this double blind, randomized controlled trial was to evaluate the 36-month clinical performance of the layering technique (incremental [IF] vs. bulk-fill [BF]) in posterior composite resin restorations ...
-
(Academic Press, 2019)In the hyperarid Atacama Desert (Northern Chile), the economic and social development is supported using fossil groundwater. The groundwater extraction (GWE)has significantly increased over the last 30 years, reaching ∼4.2 ...
-
(Elsevier B.V., 2019)In this work, precipitation and sol-gel mixed procedures were used to prepare a TiO2@Fe3O4 nanocomposite. The X-ray diffraction (XRD)and selected area electron diffraction (SAED)results unmistakably elucidated the tetragonal ...
-
(Taylor and Francis Ltd., 2019)A rapid screening method is described for the determination of paralytic shellfish toxins (PST), in fresh marine vectors (bivalves and gastropods), at levels ranging from 0.05 to 5.0 mg STX-eq kg−1. PST are extracted from ...
-
Graphene/nickel oxide nanocomposites against isolated ESBL producing bacteria and A549 cancer cells (Elsevier Ltd, 2019)The synthesis of nickel oxide nanoparticles (NiO NPs)and graphene/nickel oxide nanocomposites (Gr/NiO NCs)was performed using a simple chemical reduction method. Powder X-ray diffraction (XRD)and thermogravimetric analysis ...
-
(Society for Industrial and Applied Mathematics Publications, 2019)We characterize the subdifferential of the supremum function of finitely and infinitely indexed families of convex functions. The main contribution of this paper consists of providing formulas for such a subdifferential ...
-
(Sociedad Chilena de Obstetricia y Ginecologia, 2019)Background: Adolescents who engage in sexual activity in a non-romantic relationship may develop patterns of sexual activity that lead to negative health outcomes such as unplanned pregnancy, sexually transmitted infections, ...
-
(Elsevier Ltd, 2019)Aggregation operators consist of mathematical functions that enable the combining and processing of different types of information. The aim of this work is to present the main contributions in this field by a bibliometric ...
-
(Springer Verlag, 2019)We consider the Cauchy problem for the energy critical heat equation {ut=Δu+|u|4n−2uinRn×(0,T)u(⋅,0)=u0inRn in dimension n = 5. More precisely we find that for given points q 1 ,q 2 ,..,q k and any sufficiently small T ...
-
(Cambridge University Press, 2019)The study of the stone sculpture production process is subject to the preservation and visibility of tool traces and surface finishes. In this article it is proposed that the parameters developed in conservation for the ...
-
(Frontiers Media S.A., 2019)Copyright © 2019 Robledo, Gutiérrez, Barría, Lhorente, Houston and Yáñez.Sea lice (Caligus rogercresseyi) are ectoparasitic copepods which have a large negative economic and welfare impact in Atlantic salmon (Salmo salar) ...
