(2014)A bio-rack system was developed for treating Cu-contaminated freshwaters. Each pilot constructed wetland (CW, 110dm3) contained 15 perforated vertical pipes filled with a mixture of gravel (diorite; 80%) and perlite (20%) ...
-
(Sociedad Chilena de Quimica, 2013)Several natural compounds containing a coumarin moiety have been reported. They have multiple biological activities, e. g. , as scavengers of reactive oxygen species (ROS) and to reduce the inflammatory processes by ...
-
(Sociedad Chilena de Quimica, 2013)Yellow blocks from the archaeological site Playa Miller 7 (PLM7), on the coast of Atacama Desert in northern Chile, were analyzed by Raman spectroscopy and X-ray fluorescence (XRF) portable. Our results identify for the ...
-
(Sociedad Chilena de Quimica, 2013)ABSTRACT The microbiological transformation of ent-beyer-15-en-18-ol 1 and ent-beyer-15-en-19-ol 2, using Mucor plumbeus, resulted in hydroxylated products. After nine days of incubation, 15?,16?-epoxide-ent-beyeran-7b,18-diol ...
-
(2012)Since the preferential body temperature should positively correlate with physiological performance, behavioural fever should enhance an organism's immune response under an immune challenge. Here we have studied the ...
-
(2013)Natural protected areas (ASP) located in the south-central Chile (Región Metropolitana-Región de la Araucanía) are a conservation relict embedded in agricultural and silvicultural matrices. We compared the taxonomic diversity ...
-
(2013)Broad-scale richness gradients are closely associated with temperature and water availability. However, historical and evolutionary processes have also contributed to shape current diversity patterns. In this paper we focus ...
-
(2014)A material characterization of two artworks discovered in the San Francisco Church, Santiago, Chile, was performed using micro-Raman spectroscopy. Structural painted beams and a wall painting that belong to the same time ...
-
(2013)Background: Birds are important mobile link species that contribute to landscape-scale patterns by means of pollination, seed dispersal, and predation. Birds are often associated with habitats modified by small mammal ...
-
(2013)The coastal mountain range of Los Choros (Coquimbo Region) is a natural system with geomorphological characteristics (e.g., dunes, ravines and extensive plains at sea level) which allow for a flora and fauna adapted to ...
-
(2014)We report new experimental data regarding the transverse magnetoresistance measured in a family of thin gold films of different thickness with the electric field E oriented perpendicular to the magnetic field B (both fields ...
-
(2012)A total of ten microsatellite loci were isolated and characterized in the endangered freshwater catfish Trichomycterus areolatus from Chile. Samples from three separate watersheds were also analyzed. The mean number of ...
-
(2014)We study the propagation of non-diffracting images in kagome photonic lattices. In a weak-coupling regime (discrete approach), the linear spectrum is composed by only three bands, including a completely degenerated and ...
-
(2013)In this paper, we examine a nonlinear magnetoinductive dimer and compute its linear and nonlinear symmetric, antisymmetric and asymmetric modes in closed-form, in the rotating-wave approximation. A linear stability analysis ...
-
(2013)How high-alpine plants confront stochastic conditions for animal pollination is a critical question. We investigated the effect of temperature on potential flower longevity (FL) measured in pollinator-excluded flowers and ...
-
(2013)The Torrent Duck (Merganetta armata) inhabits the torrential rivers of the Andean mountains. As part of a long-term study, two rivers important for hydroelectric production were surveyed in Central Chile. Monthly indices ...
-
(2013)The spinor class field for a genus of orders of maximal rank in a quaternion algebra a over a number field K is an abelian extension Σ/K provided with a distance function associating elements of the corresponding Galois ...
-
(2013)The roles of testosterone (T) during reproduction are often complex and vary among and within vertebrate taxa and locations, making general hypotheses relating T to breeding behavior and success difficult to integrate. In ...
-
(Elsevier Ireland Ltd, 2013)Codons expanded by a silent position (quadruplet or tetracodons) may solve the conundrum that at life's origins, the weak tricodon-anticodon interactions could not promote translation in the absence of complex ribosomes. ...

(2013)How much do ecosystems contribute to the wellbeing of rural populations in developing nations? In this article we provide an answer to this question through an eco-social study of two provisioning ecosystem services (wood ...
