Numerical simulation of stresses in functionally graded HCS-MgO cylinder using iterative technique and finite element method
(2022)In this study, a thick hollow axisymmetric functionally graded (FG) cylinder is investigated for steady-state elastic stresses using an iteration technique and the finite element method. Here, we have considered a ... -
Numerical study on cyclic response of end-plate biaxial moment connection in box columns
(2020-04)The 2008 Wenchuan-China earthquake showed the importance of considering the bidirectional seismic action as a cause of failure in column hinge mechanisms. Subsequently, the large 2011 Tohoku-Japan earthquake revealed that ... -
Nutrition labeling schemes and the time and effort of consumer processing
(2019-02-19)Guideline Daily Amount (GDA) and nutrition tables are the most used front-of-pack (FOP) nutrition labeling schemes in the world; however, they are hard to process considering the nutritional knowledge, effort, and time ... -
Obesidad en lactantes: efecto protector de la lactancia materna versus fórmulas lácteas
(2020-06)El objetivo del trabajo fue analizar el posible efecto protector de la lactancia materna respecto a la obesidad infantil versus fórmulas lácteas. Se consultaron las bases de datos PubMed, Web of Science y Scielo, considerándose ... -
Observations from a parametric study of the seismic design of soil nailing
(2018-05)A parametric study of the seismic design of soil-nailed walls is performed. Values of a set of geometrical and mechanical parameters for the nail and soil of a slope have been varied to assess their effects on the global ... -
Observations on the ontogeny of butterfish Stromateus stellatus larvae (Pisces: Stromateidae) off central Chile
(2018)Although larvae of the starry butterfish Stromateus stellatus (Family Stromateidae) are often observed in coastal waters of the southeastern Pacific Ocean, there is no formal description of the species’ early development. ... -
Obstrucción intestinal por Ascaris Lumbricoides
(2009)Varón de 71 años, sin antecedentes morbidos, ingresa al Servicio de Urgencia del Hospital Clínico Herminda Martín por cuadro de siete días de evolución caracterizado por ausencia de deposiciones, dolor abdominal, vómitos ... -
Obtención de hidrolizados de alginato y su caracterización
(2019)Se llevó a cabo el proceso de hidrólisis de alginato (Sigma Aldrich-A2033) catalizada por la enzima alginato liasa producida por la cepa H1 (bacteria no identificada), con el fin de la obtención de hidrolizados de alginato ... -
Occurrence and Distribution of Deltamethrin and Diflubenzuron in Surface Sediments from the Reloncaví Fjord and the Chiloé InnerSea (~ 39.5ºS –43ºS), Chilean Patagonia
(2018-03)Surface sediments from Reloncaví Fjord and the Chiloé inner sea in Chilean Patagonia were extracted and analyzed to estimate deltamethrin and diflubenzuron levels. These antiparasitary pesticides have been used for decades ... -
Occurrence of volatile organic compounds (VOCs) in Liverpool Bay, Irish Sea
(2007)Surface seawater samples were collected in the Irish Sea and Liverpool Bay area from the R.V. Prince Madog during the period of 25–31 of March 2006. VOCs were purged with nitrogen, pre-concentrated on a SPME fibre and ... -
Ocean Acidification, Consumers' Preferences, and Market Adaptation Strategies in the Mussel Aquaculture Industry
(2019-04)Ocean acidification (OA) is one of the largest emerging and significant environmental threats for the aquaculture industry, jeopardizing its role as an alternative for supporting food security. Moreover, market conditions, ... -
Octopods of the Canary Islands. New records and biogeographic relationship
(2019)Two octopod species are reported from the Canary Islands (eastern Atlantic Ocean) for the first time: the deep sea four-horn octopus, Pteroctopus tetracirrhus (Delle Chiaje, 1830) and the gelatinous giant octopus, Haliphron ... -
Ocular accommodative response is modulated as a function of physical exercise intensity
(2019)Purpose: The present study aimed (1) to examine the impact of two high-intensity interval training (HIIT) protocols differing in exercise intensity (low intensity and high intensity) on the dynamic accommodative response ... -
El ocultamiento del símbolo y la imaginación: repercusiones en el sistema educativo actual
(2022)En el presente trabajo teórico-reflexivo se abordan las nociones del símbolo y la imaginación como facultades cardinales para el desarrollo individual y social del ser humano. Se acentúa el interés en la concatenación de ... -

On an adaptive stabilized mixed finite element method for the Oseen problem with mixed boundary conditions
(2020-06)We consider the Oseen problem with nonhomogeneous Dirichlet boundary conditions on a part of the boundary and a Neumann type boundary condition on the remaining part. Suitable least squares terms that arise from the ... -
On eleven-dimensional supergravity and Chern–Simons theory
(2012)We probe in some depth into the structure of eleven-dimensional, osp(32|1)-based Chern–Simons supergravity, as put forward by Troncoso and Zanelli (TZ) in 1997. We find that the TZ Lagrangian may be cast as a polynomial ... -
On stabilization of Maxwell-BMS algebra
(2020-04-14)In this work we present different infinite dimensional algebras which appear as deformations of the asymptotic symmetry of the three-dimensional Chern-Simons gravity for the Maxwell algebra. We study rigidity and stability ... -
On stabilized mixed methods for generalized Stokes problem based on the velocity–pseudostress formulation: A priori error estimates
