(Universidad de Chile, 2021)La génesis de los depósitos de magnetita-apatito o iron oxide-apatite (IOA), fuentes históricas de hierro a nivel mundial, ha sido intensamente debatida por décadas. Gran parte de este debate se ha centrado en el depósito ...
-
(MDPI, 2021)(1) Background: Earwax might provide the long-term concentration of substances that are altered in chronic diseases. Standardised earwax extraction has to be exclusively performed by clinicians. We investigated the safety, ...

Thermal evolution of Andean iron oxide-apatite (IOA) deposits as revealed by magnetite thermometry (Nature, 2021)Magnetite is the main constituent of iron oxide–apatite (IOA) deposits, which are a globally important source of Fe and other elements such as P and REE, critical for modern technologies. Geochemical studies of magnetite ...
-
(EDP Sciences, 2021)In this work we study the semi-discrete linearized Benjamin-Bona-Mahony equation (BBM) which is a model for propagation of one-dimensional, unidirectional, small amplitude long waves in non-linear dispersive media. In ...
-
(Oxford, 2021)During earthquakes, structural damage is often related to soil conditions. Following the 2014 April 1 M-w 8.1 Iquique earthquake in Northern Chile, damage to infrastructure was reported in the cities of Iquique and Alto ...
-
(Universidad de Chile, 2021)El presente trabajo de tesis tiene por objetivo establecer posibles optimizaciones en los procesos de licitación de insumos críticos para plantas concentradoras en BHP Minerals Americas, en base a una revisión de los últimos ...

(Universidad de Chile, 2021)El problema de minimizar k-sum lateness en una máquina es una generalización de los problemas de minimizar maximum lateness y total lateness, casos que se recuperan cuando k=1 y k=n respectivamente, y consiste en encontrar ...
-
(Universidad de Chile, 2021)El cambio climático en conjunto con la creciente demanda de energía a nivel mundial, han llevado a la búsqueda de nuevas fuentes de energía capaces de abastecer al mercado sin ocasionar un elevado impacto ambiental. Una ...
-
(Universidad de Chile, 2021)El trabajo de título se desarrolla con IVAN DRIVE, una startup del mercado de seguridad para vehículos que ofrece un servicio ante el robo de vehículos por medio de un dispositivo de diseño propio. Previo al estudio, poseen ...

(IOP, 2021)This research reports the synthesis of copper oxide nanoparticles (CuONP) functionalized by the polar monomers acrylonitrile (ACN) and methyl methacrylate (MMA). The synthesis was achieved by a practical exchange ligand ...
-
(Frontiers Media, 2021)The notion of social belongingness has been applied to different scales, from individual to social processes, and from subjective to objective dimensions. This article seeks to contribute to this multidimensional perspective ...
-
(Polish Acad Sciences Inst Mathematics-IMPAN, 2021)A construction analogous to that of Godefroy-Kalton for metric spaces allows one to embed isometrically, in a canonical way, every quasi-metric space (X, d) in an asymmetric normed space F-a (X, d) (its quasi-metric free ...
-
(American Physical Society, 2021)We use quantum scattering theory to study a fixed quantum system Y subject to collisions with massive particles X described by wave packets. We derive the scattering map for system Y and show that the induced evolution ...
-
(Elsevier, 2021)We use state-of-the art estimation approaches to obtain mode-specific values of travel time savings (VTTS) based on pooled RP/SP travel choice data of Zurich workers. Unlike the large majority of time valuation studies, ...
