(Universidad de Chile, 2020)El trabajo se realizó en ABC Chile S.A. cuyo giro es agente de naves. La agencia en Chile tiene dos funciones principales: apoyar la operación de los buques y, administrar y vender los espacios en las naves para la carga ...
-
(MDPI, 2020)Generating strategies and techniques to feed the increasing world population is a significant challenge under climate change effects such as drought. Rural areas are especially sensitive to such effects as they are unable ...
-
(EDP Science, 2020)Context. To understand the formation of planetary systems, it is important to understand the initial conditions of planet formation, that is, the young gas-rich planet forming disks. Spatially resolved, high-contrast ...
-
(Copernicus gesellschaft MBH, 2020)This study investigates the chemical composition of PM2.5 collected at a central location in Beijing, China, during winter 2016 and summer 2017. The samples were characterised using direct-infusion negative-nano-electros ...
-
(Association for Computing Machinery, USA, 2020)BACKGROUND: Knowing their current position in the surroundings constitutes one of the biggest challenges faced by people with visual disabilities when they move around. For them, it is difficult to be aware of the direction ...
-
(Universidad de Chile, 2020)La caracterización de materiales en condiciones dinámicas representan nuevos desafíos para el desarrollo tecnológico. En base a lo anterior, se establece construir una barra de compresión de Hopkinson (SHPB, por sus siglas ...
-
(Universidad de Chile, 2020)La Vicepresidencia de Proyectos de Codelco, actualmente se encuentra ejecutando un total de 9 proyectos en sus fases de construcción y 10 proyectos en las fases de Prefactibilidad y Factibilidad. En este contexto, Codelco ...

(MDPI, 2020)Gas pipeline systems are one of the largest energy infrastructures in the world and are known to be very efficient and reliable. However, this does not mean they are prone to no risk. Corrosion is a significant problem in ...
-
(EDP Science, 2020)Context. In recent decades, thousands of substellar companions have been discovered with both indirect and direct methods of detection. While the majority of the sample is populated by objects discovered using radial ...
-
(EDP Science, 2020)Aims. To advance our knowledge of star formation, in addition to statistical studies and large surveys of young stellar objects (YSOs), it is important to carry out detailed studies towards particular objects. Given that ...
-
(EDP, 2020)Aims. We aim to study vertical settling and radial drift of dust in protoplanetary disks from a different perspective: an edge-on view. An estimation of the amplitude of settling and drift is highly relevant to understanding ...
-
(Springer, 2021)In Latin America, there is scarce comparative research on variables associated with the perception of climate change. This hinders the ability of governments to take mitigation and adaptation measures in the face of the ...
-
(Springer Heidelberg, 2020)A ca. 2.5 million m(3) landslide occurred in August 2018 in the Yerba Loca valley, Andes Main Cordillera (33 degrees 15 ' S), at about 4000 m a.s.l. The Yerba Loca landslide is a multirotational slide, with a main scarp ...
-
(IOP Publishing, 2020)ISO-Oph 2 is a wide-separation (240 au) binary system where the primary star harbors a massive (M-dust similar to 40M(circle plus)) ring-like disk with a dust cavity similar to 50 au in radius and the secondary hosts a ...
-
(Elsevier, 2020)In 2007, a sequence of geophysical events occurred in Chilean Patagonia that manifested themselves in a series of earthquakes and a fjord tsunami, causing many months of disruption to the normal functioning of a region not ...
-
(Pergamon-Elsevier Science, 2020)Due to the growing environmental issues and high energy consumption, there is an emergent need to synthesize the multifunctional materials to reduce energy consumption. Hence, we synthesized the Pd/Mn(Mn0.36Pd0.64)O-4 ...
-
(IOP Publishing, 2020)Phase-curve measurements provide a global view of the composition, thermal structure, and dynamics of exoplanet atmospheres. Although most of the dozens of phase-curve measurements made to date are of large, massive hot ...
-
(IOP Publishing, 2020)A photonic crystal (PhC) based optical component paves a path to the upcoming all-optical computer processors. All the components can be realized with the help of PhCs. In particular, optical gates have played a major part ...
-
(Assoc Computing Machinery, USA, 2020)The predecessor problem is a key component of the fundamental sorting-and-searching core of algorithmic problems. While binary search is the optimal solution in the comparison model, more realistic machine models on integer ...
-
(Wiley, 2020)In this article, we develop proportional, fractional-integral, and derivative (PI lambda D) controllers for the regulation and tracking problems of nonlinear systems. The analytic results are obtained by extending the ...
