Physical properties of near-Earth asteroid (2102) Tantalus from multiwavelength observations
(2022)Between 2010 and 2017, we have collected new optical and radar observations of the potentially hazardous asteroid (2102) Tantalus from the ESO NTT and Danish telescopes at the La Silla Observatory, and from the Arecibo ... -
Proof of concept of a novel frictional shock absorber; analytical model and experimental analysis
(2021-03)Recurrent impact protection devices usually need to dissipate large amounts of energy to prevent damage to the infrastructure they protect and to make efficient use of them. This requires that protection devices consider ... -
Probable Relationship between COVID-19, Pollutants and Meteorology: A Case Study at Santiago, Chile
(2021-05)We present here a study about the possible spread of covid-19 pandemic between human’s beings through aerosols contained in urban air polluted by respirable particulate matter and tropospheric ozone, as well as the incidence ... -
Port governance and cruise tourism
(2021-05)Cruise activities, until 2020, have presented a significant increase in revenue, as well as number of cruises and passengers transported, and it has become a challenge for ports to respond to this demand for services. ... -
Declaración del yo físico por estudiantes universitarios en los medios digitales: una perspectiva de género
(2021-02)Los objetivos de esta investigación fueron describir el “yo físico afecto en medios digitales” en universitarios chilenos y reconocer dinámicas y patrones de comportamiento digital/virtual que reflejen mandatos y conductas ... -
A review study of application of artificial intelligence in construction management and composite beams
(2021-06)This paper is aimed to review the use of artificial intelligence (AI) algorithms in diverse civil engineering applications such as predicting and evaluating the different parameters of composite beams and shear connectors ... -
Analysis of a momentum conservative mixed-FEM for the stationary Navier–Stokes problem
(2021-09)In this paper, we propose and analyze a new momentum conservative mixed finite element method for the Navier–Stokes problem posed in nonstandard Banach spaces. Our approach is based on the introduction of a pseudostress ... -
A fully-mixed finite element method for the coupling of the Navier–Stokes and Darcy–Forchheimer equations
(2021-05)In this work we present and analyze a fully-mixed formulation for the nonlinear model given by the coupling of the Navier–Stokes and Darcy–Forchheimer equations with the Beavers–Joseph–Saffman condition on the interface. ... -
Entrepreneurial intention: A gender study in business and economics students from Chile
(2021)The study of entrepreneurial intention sheds new light on the complex dynamics of entrepreneurial behavior. This research contributes to the academic debate by examining the gap in studies on entrepreneurial intention in ... -
Effect of nail spacing on the global stability of soil nailed walls using limit equilibrium and finite element methods
(2021-01)The limit equilibrium method LEM is widely used for static and pseudo-static soil nailing designs. Soil nailed wall stability is usually evaluated based on a global factor of safety FSG under a predefined failure mechanism. ... -
Economic construction management of composite beam using the head stud shear connector with encased cold-formed steel built-up fix beam via efficient computer simulation
(2021-05)With regard to economic efficiency, composite fix beams are widely used to pass longitudinal shear forces across the interface. The current knowledge of the composite beam load-slip activity and shear capability are ... -
Identidad digital y conectividad: conocimiento y actitudes en estudiantes universitarios chilenos
(2021-02)El objetivo de esta investigación fue determinar el nivel de conocimiento y las actitudes de estudiantes universitarios chilenos frente a los conceptos de identidad y reputación digital y sus hábitos de conectividad a ... -
Contributions of subjective well-being and good living to the contemporary development of the notion of sustainable human development
(2021)The article analyzes the contributions of the notions of Good Living attributable to epistemologies, traditions, and subjective well-being at work, given the current changes in the working context, to enrich the concept ... -
Characterization of the digital identity of Chilean university students considering their personal learning environments
(2021)At present, our online activity is almost constant, either producing information or consuming it, both for the social and academic fields. The spaces in which people move and travel every day, innocently divided between ... -
Biocidal activity of citrus limetta peel extract mediated green synthesized silver quantum dots against MCF-7 cancer cells and pathogenic bacteria
(2021-04)Monodispersed silver quantum dots (Ag QDs) of sub 5 nm range are prepared through a facile and size-controllable green synthesis route using sweet lime (Citrus limetta) peel (SLP) extract. Powder X-ray diffraction studies ... -
Bactericidal activity of Moringa oleifera leaf extract assisted green synthesis of hierarchical copper oxide microspheres against pathogenic bacterial strains
(2021-02)Hierarchical copper oxide (CuO) microspheres were prepared by Moringa oleifera (M. oleifera) leaf extract assisted green synthesis method. The structural, chemical, and morphological features of the hierarchical CuO ... -
Nivel de conciencia de la actividad y creación de información en medios digitales. Un estudio de caso en estudiantes universitarios chilenos
(2021-08)Los objetivos de esta investigación fueron establecer el grado de conciencia de la actividad en la red en un grupo de estudiantes universitarios y, además, determinar cómo dicho grado condiciona la creación de información. ... -
La alimentación animal y su impacto en la nutrición humana. ¿Qué está pasando en Latinoamérica?
(2021-07)Cuando revisamos la publicación de Palmieri y colaboradores, realizada en el 2014 (1) en relación con el uso de antibióticos en animales criados para el consumo humano, nos preguntamos: ¿Qué pasa hoy en día con este tema? ... -
An adaptive multiscale hybrid-mixed method for the Oseen equations
(2021)A novel residual a posteriori error estimator for the Oseen equations achieves efficiency and reliability by including multilevel contributions in its construction. Originates from the Multiscale Hybrid Mixed (MHM) method, ... -
