Abstract

The massive binary HDE 228766 is composed of an O type primary and an evolved secondary. However, previous qualitative analyses of the composite spectrum have led to a wide discussion about whether the secondary is an Of or a Wolf-Rayet star. We use new observations and our novel QER20 package to disentangle for the first time the spectra of the two stellar components and obtain artefact free reconstructed spectra, yielding the more accurate and reliable spectral classifications of O7.5 V((f))z for the primary and O6 Iaf for the secondary. The emission features of the P-Cygni profiles of the H\b{eta} and He I 5876 {\AA} lines, present in the reconstructed spectrum of the secondary, show that this star is at an initial phase of its transition to the WN evolutionary stage. A previously unobserved variable emission, composed of at least four independent features, is seen since 2014 superposed to the H{\gamma} absorption line. Our analysis reveals that these emission features originate from a physically extended region. This could be explained by an episode of enhanced mass-loss in the scenario of a non conservative evolution of the binary.

Abstract

HD165052 is a short-period massive eccentric binary system that undergoes apsidal motion. As the rate of apsidal motion is directly related to the internal structure constants of the binary components, its study allows to get insight into the internal structure of the stars. We use medium- and high-resolution spectroscopic observations of HD165052 to provide constraints on the fundamental properties of the binary system and the evolutionary state of its components. We apply a spectral disentangling code to reconstruct artefact-free spectra of the individual stars and derive the radial velocities (RVs) at the times of the observations. We perform the first analysis of the disentangled spectra with the non-LTE model atmosphere code CMFGEN to determine the stellar properties. We derive the first self-consistent orbital solution of all existing RV data, including those reported in the literature, accounting for apsidal motion. We build, for the very first time, dedicated stellar evolution tracks with the Cl\'es code requesting the theoretical effective temperatures and luminosities to match those obtained from our spectroscopic analysis. The binary system HD165052, consisting of an O6.5V((f)) primary and an O7V((f)) secondary, displays apsidal motion at a rate of (11.30+0.64-0.49)$\deg$yr$^{-1}$. Evolutionary masses are compared to minimum dynamical masses to constrain the orbital inclination. Evolutionary masses Mev,P=24.8$\pm$1.0M$_\odot$ and Mev,S=20.9$\pm$1.0M$_\odot$ and radii Rev,P=7.0+0.5-0.4R$_\odot$ and Rev,S=6.2+0.4-0.3R$_\odot$ are derived, and the inclination is constrained to 22.1$\deg\le i\le 23.3\deg$. Theoretical apsidal motion rates, derived assuming an age of 2.0+/-0.5 Myr for the binary, are in agreement with the observational determination. The agreement with theoretical apsidal motion rates enforces the inferred values of the evolutionary stellar masses and radii., Comment: 17 pages. arXiv admin note: text overlap with arXiv:2205.11207

Abstract

The determination of the state of health of batteries is a necessary parameter for planning the acquisition of new units in storage systems for energy support. Currently, there are many investigations focused on determining the of the state of health of batteries of different types of batteries, as well as their useful life. However, none have analysed the of the state of health of batteries by changes in the transmittance of the electrolyte for a specific frequency, as proposed in this article. The project from which this article derives considered different health states of lead-acid batteries. The percentage of optical transmittance of the four central cells of the battery was analyzed, generating a classification pattern that allowed the approximate value of battery health to be obtained from the transmittance. The variation of the battery electrode is verified according to the changes in the state of health measured in the electrolyte. This method can be applied to batteries online. The proposed method for determining battery health is a non-destructive and cost-effective way to assess the remaining capacity of batteries. It could be used to extend the lifetime of batteries in storage systems and to help to ensure that systems have the capacity to meet energy demands. [ABSTRACT FROM AUTHOR]

12. Aportes de la educación religiosa escolar y el pensamiento humanista de Emmanuel Mounier en la construcción de persona en estudiantes de grado sexto y séptimo del colegio santa teresita del niño Jesús, ubicado en la ciudad de Barrancabermeja, Santander

Abstract

La educación ha sido el pilar fundamental de todas las culturas y civilizaciones; ya en los primeros humanos se empezó a notar un deseo de aprender manifestado en las dificultades que la naturaleza les imponía, tales como la adquisición de alimentos, atuendos para abrigar sus cuerpos y el desarrollo paulatino de las herramientas de caza. Dichos aprendizajes fueron durante milenios el producto del ensayo y el error perpetuados a través de la tradición oral (Marescalchi, LasHeras, Martínez de Pérez, Elisa de Yong, & Ramallo, 2018, pág. 13).

Abstract

The estimation of the state of health (SOH) of lead-acid batteries for electrical energy storage is an important factor when planning their replacement and energy management. There are many methods to calculate this parameter. The novelty of this work is that it employs an optical method that produces compelling results showing the variation of the UVC transmittance of the electrolyte when the battery has different SOH levels, which is a novel alternative to the existing one of ampere counting, which is also experimented within this work.

Abstract

Given the rise of satellite television, radio telescopes in the Ku‐band (12–18 GHz) constitute a potential alternative to introduce low‐scale astronomical observatories and amateur astronomers to radio astronomy. In this paper, we show a methodology for the calibration of Ku‐band radio telescopes and the evaluation of the techniques used for the observation of celestial bodies in this frequency range. To reduce the pointing error, we present a method of observation through matrix windows around the Sun. By observing the solar transits, our methodology allows to determine the system temperature, the beamwidth, the gain, the effective area, and the efficiency of the radio telescope. In addition, we developed the Compact Radio Telescope (CRT) software, designed to perform the calibration, and carry out observations. We tested our methodology with the Ku‐band radio telescope of the Observatorio Astronómico of the Universidad Tecnológica de Pereira (OAUTP), Colombia. After observing the Sun and the Moon, we obtained a brightness temperature of 8,600 ± 800 K and 240 ± 50 K, and radiation fluxes of 2,970,000 ± 690,000 Jy and 55,000 ± 10,000 Jy, respectively. These observations demonstrated the usefulness of our methodology and CRT software in the calibration of compact Ku‐band radio telescopes for the observation of celestial bodies in radio waves.
