(Frontiers Media, 2020)The Andes is the longest cordillera in the world and extends from northern South America to the southern extreme of the continent (from 11 degrees N to 53 degrees S). The Andes runs through seven countries and is characterized ...
-
(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 ...
-
(Nature Publishing Group, 2018)A harmful algal bloom (HAB) of the raphidophyta alga Pseudochattonella cf. verruculosa during the 2016 austral summer (February-March) killed nearly 12% of the Chilean salmon production, causing the worst mass mortality ...
-
(Wiley, 2020)The long-term hydroclimatic variability in Santiago (Chile) was analysed by means of a new 481-year (1536-2016 CE) tree-ring reconstruction of the Standardized Precipitation Evapotranspiration Index (SPEI) of August, ...
-
(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 SCIENCE BV, 2005-09-14)The rhodium(l) complexes, cis-[Rh(CO)(2)(amine)(2)] (PF6) (amine = pyridine, 2-picoline, 3-picoline, 4-picoline, 3,5-lutidine or 2,6-lutidine) dissolved in methanol under carbon monoxide atmosphere are effective catalysts ...
-
(Bentham Science, 2020)Background: Obesity is a major health problem associated with increased comorbiditics, which are partially triggered by inflammation. Proinflaminatory macrophage infiltration in adipose tissue of individuals with obesity ...
-
(WILEY-V C H VERLAG GMBH, 2000-06-20)A large number of carboxylic groups were introduced onto chitosan by grafting with poly(acrylic acid) as an efficient way of modification. The reactions were carried out in a homogeneous aqueous phase by using potassium ...
-
(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 ...
-
(American Chemical Society, 2013)Preferential solvation in aromatic nucleophilic substitution reactions is discussed using a kinetic study complemented with quantum chemical calculations. The model system is the reaction of a series of secondary ...
-
(1975)A solvent and/or environmental effect has been introduced into the MO CNDO/2 calculation of a model hydrogen bonded system. Proton potential curves, potential energy, dipole moments, the polarizability component parallel ...
-
(1974)Second order perturbation theory (SOP) has been used to introduce electronic correlation effects on CNDP/2 calculated quantities like stabilization energy, proton potential curves, intermolecular dependence on distance and ...
-
(Springer New York LLC, 1998)© Springer-Verlag 1998. Recently, the proton affinity (PA) of ozone was experimentally determined by Cacace and Speranza [Science (1994) 265: 208] using a bracketing technique that involved the proton transfer (PT) reactions: ...
-
(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 ...
-
(Elsevier, 2015)In this work, we report the heat rectifying capability of a-helices. Using molecular dynamics simulations we show an increased thermal diffusivity in the C-Terminal to N-Terminal direction of propagation. The origin of ...
-
(American Chemical Society, 2014)Recent evidence has shown a correlation between the heat diffusion pathways and the known allosteric communication pathways in proteins. Allosteric communication in proteins is a central, yet unsolved, problem in ...
