(Nature Research, 2021)The subduction of oceanic plates beneath continental lithosphere is responsible for continental growth and recycling of oceanic crust, promoting the formation of Cordilleran arcs. However, the processes that control the ...
-
(Copernicus Gesellschaft MBH, 2021)Several magnetic measurements and theoretical developments from different research groups have shown certain relationships with worldwide geological processes. Secular variation in geomagnetic cutoff rigidity, ...
-
(MDPI, 2021)Jamming attacks in wireless sensor networks (WSNs) scenarios are detrimental to the performance of these networks and affect the security and stability of the service perceived by users. Therefore, the evaluation of the ...
-
(Elsevier, 2021)Ice and snow in the Central Andes contain significant amounts of light-absorbing particles such as black carbon. The consequent accelerated melting of the cryosphere is not only a threat from a climate perspective but ...
-
(BMC, 2021)Background Microbes are present in almost every environment on Earth, even in those with extreme environmental conditions such as Antarctica, where rocks may represent the main refuge for life. Lithobiontic communities are ...
-
(Springer, 2021)This paper proposes a methodology for measuring Quality of Employment (QoE) deprivation from a multidimensional perspective in six Central American countries (Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and ...
-
(MDPI, 2021)The unprecedented size of the 2017 wildfires that burned nearly 600,000 hectares of central Chile highlight a need to better understand the climatic conditions under which large fires develop. Here we evaluate synoptic ...
-
(MDPI, 2021)Renewable generation technologies are rapidly penetrating electrical power systems, which challenge frequency stability, especially in power systems with low inertia. To prevent future instabilities, this issue should ...
-
(Universidad de Chile, 2021)El objetivo de la presente tesis es estudiar hallazgos de osamentas, restos arqueológicos, paleontológicos o similares y los costos involucrados al retrasar el avance de una obra civil. Para esto se debe realizar una ...
-
(Copernicus Gesellschaft MBH, 2020)We investigate the influence of regional atmospheric circulation on the evaporation of a saline lake in the Altiplano (also known as the Andean Plateau) region of the Atacama Desert. For that, we conducted a field experiment ...
-
(Springer, 2021)The value of travel time savings (VTTS) representing the willingness to pay to reduce travel time, consists of two components: the value of liberating time [equal to the value of leisure (VoL)] and the value of time assigned ...
-
(MDPI, 2021)The mineralogy and mineral chemistry of carbonates from various hydrothermal deposits, including volcanic-hosted Au-Cu epithermal, "Chilean Manto-type" Cu(-Ag), stratabound Mn, and Ag-Ba vein deposits from Spain and Chile, ...
-
Seasonal variation in atmospheric pollutants transport in central Chile: dynamics and consequences (Copernicus, Germany, 2021)Central Chile faces atmospheric pollution issues all year long as a result of elevated concentrations of fine particulate matter during the cold months and tropospheric ozone during the warm season. In addition to public ...
-
(Universidad de Chile, 2021)Las empresas de telecomunicaciones definen sus procesos de gestión y desarrollo con el fin de sistematizar y hacer repetible su forma de trabajo. De esa manera, buscan aumentar la eficiencia y eficacia en la construcción ...
-
(Universidad de Chile, 2021)Un anclaje de tensión es un elemento estructural utilizado para transmitir car-gas de tracción al suelo que, típicamente, está formado por un número variable de torones (cable de 7 alambres de acero trenzados helicoidalmente) ...
-
Relationship between subduction erosion and the up-dip limit of the 2014 Mw 8.1 Iquique earthquake (American Geophysical Union, USA, 2021)The aftershock distribution of the 2014 Mw 8.1 Iquique earthquake offshore northern Chile, identified from a long-term deployment of ocean bottom seismometers installed eight months after the mainshock, in conjunction with ...
-
(Universidad de Chile, 2021)En este trabajo de investigación se estudió la actividad catalítica, selectividad y estabilidad de catalizadores de níquel, soportados en materiales de rGO funcionalizado, en la reacción de metanación de CO2. Este trabajo ...
-
(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 ...
-
(Springer, 2021)During the current COVID-19 pandemic, active testing has risen as a key component of many response strategies around the globe. Such strategies have a common denominator: the limited availability of diagnostic tests. In ...
-
(Elsevier, 2021)Words are sequences of letters over a finite alphabet. We study two intimately related topics for this object: quasi-randomness and limit theory. With respect to the first topic we investigate the notion of uniform ...
