Two new species of Ascarophis (Nematoda: Cystidicolidae) in marine fishes from Chile
(2007)In this study, we describe 2 new species of Ascarophis van Beneden, 1871 (Nematoda: Cystidicolidae), found in fishes from southern Chile. Ascarophis carvajali n. sp. was found in Austrolycus depressiceps and Patagonotothen ... -
Two new species of Microcotyle (Monogenea: Microcotylidae) on intertidal fish from the south Pacific coast
(2019-12)Microcotyle is one of the most diverse and controversial genera within the family Microcotylidae. To date, 131 species have been described in Microcotyle; however, more than half have been transferred to other genera, and ... -
Two sympatric, not externally discernible, and heavily exploited deepwater species with coastal migration during spawning season: implications for sustainable stocks management of Aphanopus carbo and Aphanopus intermedius around Madeira
(2020-01)Several artisanal fisheries target deep species. These stocks are highly sensitive to overfishing because of their slow growth and late maturation. This vulnerability is higher if species concentrate during spawning ... -
Two-point method: a quick and fatigue-free procedure for assessment of muscle mechanical capacities and the 1 repetition maximum
(2018-04)The force-velocity relationship is used to evaluate the maximal capacities of active muscles to produce force, velocity, and power. the load-velocity relationship has also been used to predict the 1 repetition maximum (1RM) ... -
Two-year cosmology large angular scale surveyor (CLASS) observations: 40 GHz telescope pointing, beam profile, window function, and polarization performance
(2020-03-10)The Cosmology Large Angular Scale Surveyor (CLASS) is a telescope array that observes the cosmic microwave background (CMB) over 75% of the sky from the Atacama Desert, Chile, at frequency bands centered near 40, 90, 150, ... -
Two-year Cosmology Large Angular Scale Surveyor (CLASS) Observations: A First Detection of Atmospheric Circular Polarization at Q band
(2020-02-01)The Earth’s magnetic field induces Zeeman splitting of the magnetic dipole transitions of molecular oxygen in the atmosphere, which produces polarized emission in the millimeter-wave regime. This polarized emission ... -
Two-year Cosmology Large Angular Scale Surveyor (CLASS) Observations: A Measurement of Circular Polarization at 40 GHz
(2020-02-01)We report measurements of circular polarization from the first two years of observation with the 40 GHz polarimeter of the Cosmology Large Angular Scale Surveyor (CLASS). CLASS is conducting a multi-frequency survey ... -

(2016)El presente estudio identifica un umbral de precipitación por medio de un análisis realizado sobre la base de 99 eventos de remoción en masa, ocurridos entre los años 1960 y 2015, en la provincia de Concepción, Región del ... -
Undergraduate students’ perception of the use of text messages in L2 for learning vocabulary outside the classroom
(2016-05)El presente estudio tuvo como objetivo conocer la percepción de estudiantes con respecto al uso de mensajes de textos vía Remind1 en el aprendizaje de vocabulario en inglés. El uso de tics se ha vuelto común en los colegios ... -
Understanding biological impacts of ENSO on the eastern Pacific: an evolving scenario
(2008)The understanding of the physical nature of the El Nino Southern Oscillation (ENSO) phenomenon has gone through significant and progressive changes during the last decades. Such advances lead biologists to deal with an ... -
Unfolding of the hamiltonian triangle vector field
(2011)In this paper, we study unfoldings of the Hamiltonian triangle vector field within quadratic vector fields. We complete and correct some previous results of Żołądek -
Unifying Efficiency and Weak Efficiency in Generalized Quasiconvex Vector Minimization on the Real-line
(2009)Usually the concepts of efficient and weakly efficient solution are associated to a multiobjective optimization problem. Both notions may be described in terms of a preference relation determined by a closed convex cone ... -
Unpacking the complexity of longitudinal movement and recruitment patterns of facultative amphidromous fish
(2022)Longitudinal movement plays fundamental role in habitat colonization and population establishment of many riverine fish species. Movement patterns of amphidromous fish species at fine-scales that would allow characterizing ... -
Urban Densification Effect on Micrometeorology in Santiago, Chile: A Comparative Study Based on Chaos Theory
(2022)The concentration distribution of anthropocentric pollutants is favored by urban densifi- cation, affecting the micrometeorology in big cities. To examine this condition, chaos theory was applied to time series of ... -
