(2003-10-01)Regional and large-scale circulation anomalies associated with periods of enhanced and reduced convective cloudiness over Uruguay are studied for austral spring and summer, when rainfall associated with deep convection is ...
-
(Universidad de Chile, 2019)En esta tesis presento la evolución de las variables atmosféricas que determinan el clima planetario al variar el parámetro de oblicuidad. Usando un modelo de circulación general de la atmósfera acoplado a un océano soméro ...
-
(Academic Press Inc., 2018)We present the evolution of the atmospheric variables that affect planetary climate by increasing the obliquity by using a general circulation model (PlaSim) coupled to a slab ocean with mixed layer flux correction. We ...
-
(Universidad de Chile, 2012)En esta tesis se estudian los mecanismos físicos involucrados en el forzamiento atmosférico del océano superficial a escala estacional y sinóptica frente a Chile central. Para esto, se utilizaron observaciones disponibles ...
-
(Frontiers Media, 2020)This paper quantifies the climatological contribution of atmospheric rivers (ARs) to annual snow accumulation in the Andes Cordillera between 26.5 degrees S and 36.5 degrees S. An AR identification algorithm, and a ...

(UNIV CHICAGO PRESS, 2005-04-20)We present a coarsely sampled longitude-velocity (l-V) map of the region l = 300 degrees - 354 degrees, b = 0 degrees in the 492 GHz fine-structure transition of neutral atomic carbon (C-0 P-3(1) - P-3(0); [C I]), observed ...
-
(Oxford University, 2017)We have conducted a search for optical circumstellar absorption lines in the spectra of 16 debris disc host stars. None of the stars in our sample showed signs of emission line activity in either Hα, CaII or Na I, confirming ...
-
(Universidad de Chile, 2016)La fricción interna corresponde a la capacidad de los materiales de disipar la energía de ondas de sonido. Esta capacidad depende del tipo de material así como del tipo y cantidad de defectos que contenga. Durante muchos ...
-
(Oxford University Press, 2020)The ATOMS, standing for ALMA Three-millimeter Observations of Massive Star-forming regions, survey has observed 146 active star-forming regions with ALMA band 3, aiming to systematically investigate the spatial distribution ...
-
(Oxford University Press, 2020)We report studies of the relationships between the total bolometric luminosity (L-bol or L-TIR) and the molecular line luminosities of J = 1 - 0 transitions of (HCN)-C-13, (HCO+)-C-13, HCN, and HCO+ with data obtained from ...
-
(Oxford, 2022)Investigating the physical and chemical structures of massive star-forming regions is critical for understanding the formation and the early evolution of massive stars. We performed a detailed line survey toward six dense ...
-
(Universidad de Chile, 2015)En Chile, el sector industrial más activo en el desarrollo de la economía nacional ha sido la minería del cobre , tanto por nivel de las inversiones en cantidad y montos, como en el aporte de divisas que genera su exportación. ...
-
(Springer, 2013)Attachments of Acidithiobacillus ferrooxidans ATCC 23270 onto elemental sulfur, quartz and complex chalcopyrite were investigated by analysis of its extracellular polymeric substances as well as applying Langmuir and ...
-
(Springer, 2020)Objective This study aims to investigate the attachment of Acidithiobacillus ferrooxidans to pyrite in two different environments: fresh and saline water (water with 35 g/L of NaCl or 0.6 M). Adsorption isotherms were ...

(IOP Publishing Ltd, 2017)The spatial distribution of dust in galaxies affects the global attenuation, and hence inferred properties, of galaxies. We trace the spatial distribution of dust in five approximately kiloparsec fields of M31 by comparing ...
-
(SAGE, 2021)This article presents an exploratory model to classify public attitudes towards health systems financing and organization. It comprises 5 factors (pay-as-you-use, solidarity, willingness to contribute, mixed financing, and ...
-
(Universidad de Chile, 2010)En esta tesis se estudian remates en los cuales los oferentes compiten por el derecho a negociar con un agente. Estos remates están presentes en adquisiciones deportivas y licitaciones con alto impacto en las comunidades ...
-
(Universidad de Chile, 2019)El presente trabajo se desarrolla en una de las empresas del holding de CMPC, Papeles Cordillera S.A. cuyas instalaciones se ubican en Puente Alto. La compañía comercializa, aproximadamente, 320.000 toneladas al año de ...
