(Universidad de Chile, 2013)El Gran Conjunto Milimétrico / submilimétrico de Atacama (ALMA) es el observatorio astronómico más grande jamás construido. Se encuentra ubicado en el Llano de Chajnantor, a una altitud de 5.000 metros sobre el nivel del ...
-
(Elsevier, 2018)In this work, Ni(II) carboxylate and Ga(III) beta-diketonate complexes, were studied as precursors for the photochemical deposition of ternary metal oxide thin films with different levels of Eu(III) doping. Diluted solutions ...
-
(World Scientific Publishing Co. Pte Ltd, 2018)CFD simulations were performed for 60 human cerebral aneurysms (30 previously ruptured and 30 previously unruptured) to study the behavior of the time-averaged wall shear stress (TAWSS) with respect to the aspect ratio ...
-
(Universidad de Chile, 2020)Estudiar las estructuras presentes en discos protoplanetarios nos permite caracterizar los procesos dinámicos en ellos. Específicamente, las estructuras espirales tienen dos posibles orígenes, inestabilidades gravitacionales ...
-
(EDP Science, 2020)Aims. To advance our knowledge of star formation, in addition to statistical studies and large surveys of young stellar objects (YSOs), it is important to carry out detailed studies towards particular objects. Given that ...
-
(Elsevier Ltd, 2019)Grinding is one of the most energy-demanding processes of copper mines. Declining ore grades and harder rocks will further intensify this demand. Periods of stressed copper prices, high energy costs and climate change ...
-
(Elsevier Ltd, 2019)In the first part of this work, a solar photovoltaic system with battery storage (PV-BESS) and grid backup system to supply a SAG mill was modeled. There, the overall framework, the optimization model, and the model for ...
-
(EDP Sciences, 2013)We present high-quality VLT-FLAMES optical spectroscopy of the nebular gas in the giant star-forming region 30 Doradus. In this paper, the first of a series, we introduce our observations and discuss the main kinematic ...
-
(Universidad de Chile, 2020)En los discos galácticos, la rotación galáctica establece el movimiento global del gas, su energía y su momentum pueden transferirse hacia las escalas espaciales de las nubes moleculares. Además, en el medio interestelar, ...
-
(Universidad de Chile, 2023)El océano, que abarca el 70% de la superficie de la Tierra, presenta muchos ecosistemas, cada uno caracterizado por hábitats, temperaturas y nutrientes distintos. En el núcleo de estos ecosistemas se encuentra el microbioma ...
-
Studying the ultraviolet spectrum of the first spectroscopically confirmed supernova at redshift two (IOP Publishing Ltd, 2018)We present observations of DES16C2nm, the first spectroscopically confirmed hydrogen-free superluminous supernova (SLSN-I) at redshift z approximate to 2. DES16C2nm was discovered by the Dark Energy Survey (DES) Supernova ...
-
(Oxford University Press, 2020)Despite vast improvements in the measurement of the cosmological parameters, the nature of dark energy and an accurate value of the Hubble constant (H-0) in the Hubble-Lemaitre law remain unknown. To break the current ...
-
(Universidad de Chile, 2016)Estudiamos la formación estelar y el rol de la rotación a escalas galácticas mediante simulaciones numéricas, utilizando el código de grillas adaptativas Enzo. Parte de este trabajo se centra en estudiar tres leyes de ...
-
(Springer, 2013)The copolymerization of styrene with cyclohexene, 1-methyl-1-cyclohexene, and norbornene using ethenylbisindenylzirconium dichloride and methylaluminoxane, Et(Ind)2ZrCl2-MAO, initiating systems has been tested. The ...
-
(Oxford University Press on behalf of the Royal Astronomical Society, 2013)We present a new sample of mid-L to mid-T dwarfs with effective temperatures of 1100– 1700 K selected from the UKIDSS Large Area Survey (LAS) and confirmed with infrared spectra from X-shooter/Very Large Telescope . This ...
-
(Universidad de Chile, 2018)La investigación de esta tesis es presentada en seis capítulos, desde el Capítulo 2 al Capítulo 7. El capítulo 2 proporciona una demostración directa de una caracterización reciente de convexidad dada en el marco de ...
-
(SIAM, 2020)We are concerned with the subdifferentials of integral functionals and functions given in the form E-f(x) = f(T) f (t, x)d mu, for a possibly nonconvex normal integrand f defined on a separable Banach with separable dual ...
