N-doped titanium dioxide nanoparticles activated under visible light achieve the photocatalytic degradation of textile azo dye remazol brilliant blue
(2019-05)Dyes used in the textile industry have varied and complex structures are designed to resist degradation by external agents. Most are water soluble, resistant to chemical agents and not biodegradable, so they cannot be ... -
La nacionalidad de los hijos de inmigrantes nacidos en Chile
(2015)La nacionalidad es un atributo de la personalidad y un derecho inherente a la persona humana que consiste en el vínculo de una persona con un estado determinado que se genera por el hecho de nacer en el territorio o, por ... -
Nanostructured BiOI for air pollution control: Microwave-assisted synthesis, characterization and photocatalytic activity toward NO transformation under visible light irradiation
(2018-12)In the last decades, air pollution control has received much attention due to the increase of environmental and health problems. The design of new materials with potential applications in air pollution control systems is ... -
Narrativas que permiten comprender los procesos de resiliencia en madres y padres de hijos e hijas con diagnóstico de trastorno del espectro autista de la Escuela Diferencial y Centro Terapéutico ASPAUT de la Comuna de Chiguayante
(2017-08)El propósito de este estudio fue analizar los relatos de padres y madres que expresan sus procesos de resiliencia en relación a su hijo o hija con trastorno espectro autista en la escuela especial y centro terapéutico ... -
Narrativas, prácticas reflexivas y saberes pedagógicos en docentes en formación
(2019-12-30)Chile mantiene el desafío de formar docentes reflexivos y, en ese contexto, el objetivo del estudio fue describir la experiencia con relatos sobre lo vivido, en los centros de prácticas, y analizar su relación con la ... -
Natural zeolite reactivity towards ozone: The role of compensating cations
(2012)Among indoor pollutants, ozone is recognised to pose a threat to human health. Recently, low cost natural zeolites have been applied as alternative materials for ozone abatement. In this work, the effect of compensating ... -
Near-infrared and optical emission of WASP-5 b
(2022)Context. Thermal emission from extrasolar planets makes it possible to study important physical processes in their atmospheres and derive more precise orbital elements. Aims. Byusing newnear-infrared (NIR) and optical data, ... -
New a Posteriori Error Estimator for an Augmented Mixed FEM in Linear Elasticity
(2013)We consider an augmented mixed finite element method applied to the linear elasticity problem with non-homogeneous Dirichlet boundary conditions and derive an a posteriori error estimator that is simpler and easier to ... -
New a posteriori error estimator for an stabilized mixed method applied to incompressible fluid flows
(2019-06-15)We consider an augmented mixed finite element method for incompressible fluid flows and develop a simple a posteriori error analysis. We obtain an a posteriori error estimator that is reliable and locally efficient. We ... -
New Data on the Systematics of Comb-fin Squids Chtenopteryx spp. (Cephalopoda: Chtenopterygidae) from the Canary Islands
(2018-07-11)The systematics of the comb-fin squid species is problematic and poorly resolved. In total, 53 specimens of comb-fin squids (Chtenopteryx spp.) were caught at depths ranging from 30 to 800 m off the Canary Islands (NE ... -
New evidence of the effect of the chemical structure of activated carbon on the activity to promote radical generation in an advanced oxidation process using hydrogen peroxide
(2018-03-15)The influence of seven commercial activated carbons (ACs) to promote hydrogen peroxide decomposition and radical generation is assessed during four operating cycles. The amount of generated hydroxyl radicals is estimated ... -
New fully-mixed finite element methods for the Stokes-Darcy coupling
(2015)In this paper we introduce and analyze two new fully-mixed variational formulations for the coupling of fluid flow with porous media flow. Flows are governed by the Stokes and Darcy equations, respectively, and the ... -
New host and geographical record for Mooleptus rabuka (Nematoda: Gnathostomatidae) in the largenose catshark Apristurus nasutus (Carchariniformes: Scyliorhinidae) off Juan Fernández Archipelago, Chile
(2012)The adult stage of the gnathostomatid nematode Mooleptus rabuka, is recorded for the first time from the stomach and intestine of the largenose catshark Apristurus nasutus, off Juan Fernández Archipelago, Chile. Morphology ... -
New insight of the influence of acidic surface sites of zeolite on the ability to remove gaseous ozone using operando DRIFTS studies
(2020-01-01)Recently, natural zeolites have started to be used as alternative materials for ozone abatement from working environments. In this study, a surface response methodology based on a D-Optimal design is applied to develop ... -
New insights into the distribution, physiology and life histories of South American galaxiid fishes, and potential threats to this unique fauna
(2020-05)South American galaxiids occupy both Patagonia and the ichthyogeographic Chilean Province, encompassing glacial Andean deep lakes, shallow plateau lakes, reservoirs, short Pacific rivers and long Atlantic rivers. The total ... -
New polymorphic microsatellite markers for the pelagic fish Normanichthys crockeri
(2015)The coastal pelagic fish Normanichthys crockeri inhabits the southeast Pacific coast and is a monotypic species of the Normanichthyidae family. Its ecologically and economic importance, and the high fishing pressure it is ... -
