(Frontiers Media, 2021)This paper provides an updated review of the most relevant scientific literature related to the hydroclimate of the Andes. The Andes, the longest cordillera in the world, faces major challenges regarding climate variability ...
-
(ELSEVIER, 2006-09-15)Granular media, fluidized by a vibrating wall, is studied in the high frequency (omega -> infinity) small amplitude (A -> 0) limit. It is shown that there exists an asymptotic regime such that if the product A omega(5/4) ...
-
(Springer, 2016)This article presents a one-dimensional two-temperature hydrodynamic model to study the thermal and electrical behavior of a gallium arsenide (GaAs) PN junction solar cell. This model treats both electron and heat transfer ...
-
(Amer Inst Physics, 2016)A flow model is formulated to investigate the hydrodynamic structure of the boundary layers of incompressible fluid in a rotating cylindrical cavity with steady radial inflow. The model considers mass and momentum transfer ...
-
(American Astronomical Society, 2011-03-01)We present bolometric light curves of Type II plateau supernovae obtained using a newly developed, one-dimensional Lagrangian hydrodynamic code with flux-limited radiation diffusion. Using our code we calculate the ...
-
(Universidad de Chile, 2018)Las teorías actuales de formación planetaria concuerdan que los planetas se forman dentro de discos de gas y polvo alrededor de una estrella jóven. Sin embargo, no es claro cuál es el mecanismo detrás de la formación ...
-
(Elsevier, 2018)In this work, we present the synthesis of Ag doped TiO2 materials. The products are characterized by powder X-ray diffraction, transmission electron microscopy, X-ray photoelectron spectroscopy, nitrogen adsorption, and ...
-
(ELSEVIER, 2004-01)The reaction of pyterpy with an excess of cadmium(II) nitrate yields the novel mononuclear complex [Cd(pyterpy)(H2O)(NO3)(2)]. The crystal structure shows to the Cd(II) centre in a seven-coordinate environment and the ...
-
(Nature Publishing Group, 2017)Type II supernovae are the final stage of massive stars (above 8 M-circle dot) which retain part of their hydrogen-rich envelope at the moment of explosion. They typically eject up to 15 M-circle dot of material, with peak ...
-
(Elsevier B.V., 2019)This paper reports the hydrogenation of N-benzylideneaniline catalysed by Pd(II) compounds containing heterobidentated phosphorus-nitrogen (PN) ligands. The general formulas of the catalysts are cis-[PdCl2(L1)] and ...
-
(Elsevier, 2020)Natural hydrogeochemical backgrounds or signatures from rivers around the world show great differences depending on the geological and hydrological settings where the specific watershed is placed. This fact is especially relevant ...
-
(MDPI, 2021)Geo-thermalism has been widely recognized on the Baja California Peninsula, especially during the last decade. The current research, carried out on Bahia Concepcion, evidences the existence of geothermal springs, which get ...
-
(Nature, 2021)The decrease in freshwater input to the coastal system of the Southern Andes (40-45 degrees S) during the last decades has altered the physicochemical characteristics of the coastal water column, causing significant ...
-
(MDPI AG, 2019)© 2019 by the authors.The intensification of the hydrological cycle because of global warming raises concerns about future floods and their impact on large cities where exposure to these events has also increased. The ...

-
(Springer Heidelberg, 2015)We present a theoretical model to determine the hydromechanical boundary of an internally unstable soil subject to vertical seepage. The model is based in momentum balance equations, which consider that the system is divided ...
-
(ELSEVIER SCIENCE BV, 2012-06-15)The chromatographic methods used for the purification of PEGylated proteins are mainly Size Exclusion (SEC) and Ion Exchange Chromatography (IEX). Although the PEGylation affects the protein hydrophobicity, Hydrophobic ...
-
(Elsevier Science BV., 2016)The Los Pelambres porphyry copper deposit is located 190 km north of Santiago, Chile. A paleomagnetic and mineralogical study was conducted at this deposit to determine the effects of hydrothermal alteration on the magnetic ...
-
(Elsevier, 2014)Crustal scale strike slip fault zones have complex and heterogeneous permeability structures, playing an important role in fluid migration in the crust. Exhumed faults provide insights into the interplay among ...
