(OXFORD UNIV PRESS, 2016)Recent surveys of dust continuum emission at sub-mm wavelengths have shown that filamentary molecular clouds are ubiquitous along the Galactic plane. These structures are inhomogeneous, with overdensities that are sometimes ...
-
(Universidad de Magallanes, 2019)The available information about the environmental changes produced in the Nor-Patagonian Fjords and Channels System is dispersed and, in several cases, limited to the narrations and memories of those who lived, navigated ...
-
(2007)Several research efforts suggest that collaborative participatory simulations improve teaching and learning, increasing motivation inside the classroom. Currently, it has been mainly applied with students of primary ...
-
(Amer Geophysical Union, 2015)Hydrologic alteration due to hydropeaking reservoir operations is a main concern worldwide. Subdaily environmental flow constraints (ECs) on operations can be promising alternatives for mitigating negative impacts. However, ...
-
(Elsevier, 2020)Despite the fact that female political participation has been steadily growing over time, women's representation in politics is substantially lower than their proportion in society. In this paper, we investigate the ...
-
(Taylor & Francis, 2021)Permafrost occurs in the high Atacama Desert, and its thermal state was characterized at a study site 5,075 m a.s.l., at the lower regional altitude boundary for permafrost. The permafrost body is about 5 m thick and ...
-
(EDP Sciences, 2021)Central molecular outflows in spiral galaxies are assumed to modulate their host galaxy's star formation rate (SFR) by removing gas from the inner region of the galaxy. Outflows consisting of different gas phases appear ...
-
(Nature Publishing Group, 2019)Invasive fungal infections (IFIs) are the most frequent cause of morbidity and mortality in immunocompromised children. Voriconazole is the first-line antifungal choice in the treatment of IFIs like aspergillosis. Voriconazole ...
-
(UNIV CATOLICA DE VALPARAISO, 2006-10-15)Antibiotic-resistant coliform bacteria from raw and treated water from activated sludge of a sewage treatment plant were isolated on eosin methylene blue agar (EMB) plates in the separate presence of ampicillin, tetracycline, ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2006-07)This paper concerns a frequency-based route choice model for congested transit networks, which takes into account the consequences of congestion on the predicted flows as well as on the expected waiting and travel times. ...
-
(Elsevier Inc., 2019)Surface texturing is a promising approach to tailor friction and wear between rubbing surfaces in mechanical components. In this study, surface textures with different geometries and shapes were fabricated on hardened steel ...
-
(Springer, 2017)Our interdisciplinary research is dedicated to exploring the boundaries of stereoscopic filmmaking from an unusual viewpoint: we aim at creating 3D non-photorealistic cinema which allows conciliating a stereoscopic ...
-
(Pontificia Universidad Catolica de Chile, 2019)This study was aimed at analyzing, based on the participating teachers' emotional experience, the meanings constructed by them regarding the task of responding to diversity. To do this, the researchers analyzed 12 interviews ...
-
(Elsevier, 2015)The stability of a circular localized spot with respect to azimuthal perturbations is studied in a prototype variational model, namely, a Swift-Hohenberg type equation. The conditions under which the circular shape of the ...
-
(Elsevier B.V., 2019)© 2018 Elsevier B.V.In this work we prove that designing PPMs is equivalent to finding stopping rules for prophets. This extends the connection that any prophet type inequality can be turned into a PPM with the same ...
-
(Elsevier, 2018-08)The compartmentalization of C-4 plants increases photosynthetic efficiency, while constraining how material and energy must flow in leaf tissues. To capture this metabolic phenomenon, a generic plant metabolic reconstruction ...

(Elsevier, 2018-04-20)In this paper, we present recent data on Early Holocene human occupations from Taltal, in the coast of the Atacama Desert. We focus on evidences of mobility and subsistence economy, discussing the data in terms of a concept ...
-
(American Physical Society, 2019)Driven dissipative many-body systems are described by differential equations for macroscopic variables which include fluctuations that account for ignored microscopic variables. Here, we investigate the effect of deterministic ...
-
(Taylor and Francis Ltd., 2018)A simple model for the front of unimpeded infiltrated sand, moving as sediment transport through immobile coarse gravel particles is proposed. The theoretical celerity of the front computed by the model matched the celerity ...
