Aplicación para la evaluación técnica de la “capacidad de inserción de generación distribuida” en redes eléctricas de distribución
Authors: Lechón Luis , Samper Mauricio , Barón Gustavo 
Published: January 2021

El incremento de la instalación de Generación Distribuida (GD) puede traer beneficios a la operación de las redes de distribución, cuando las unidades son correctamente ubicadas y dimensionadas. Por el contrario, al presentarse una excesiva penetración de GD en ubicaciones inadecuadas puede conllevar problemas en los límites operacionales.
En este artículo se presenta una aplicación (herramienta computacional) sistematizada para evaluar la capacidad máxima de GD que se puede conectar a una red, garantizando la operación efectiva dentro de los parámetros de calidad preestablecidos. La misma ha sido desarrollada en software libre: Python y un Simulador de Sistemas de Distribución (OpenDSS).
En particular, la herramienta crea generadores fotovoltaicos (PVSystem) y los conecta en diferentes ubicaciones bajo dos alternativas: en barras seleccionadas aleatoriamente o en un listado de barras ingresadas por el usuario. El usuario (planificador) puede determinar: la cantidad de barras que puede conectarse GD, el porcentaje de inserción y el número de días de evaluación (N casos de Montecarlo). Además, la herramienta permite simular la incertidumbre en la demanda y la generación. En los diferentes modos de simulación se evalúan corrientes por las líneas y voltajes en las barras, que reflejan el desempeño de la red; además de las pérdidas de energía e índices de distorsión armónica. La herramienta presenta resultados gráficos y numéricos en pantallas emergentes y crea un informe en formato *.csv.

Authors: Romo Daniela , Morales Diego 
Published: January 2021

Actualmente el elevado consumo de energía eléctrica en su mayor parte es abastecido mediante el uso de fuentes no renovables, esto ha provocado efectos negativos en el medioambiente. En el presente artículo se analiza el consumo de energía de un bloque administrativo del campus universitario de la Universidad Católica de Cuenca sede Azogues; se presentan propuestas de eficiencia energética para disminuir el consumo de energía. Del levantamiento de carga se registra un consumo mensual de 35 890 kWh, el cual se consideró elevado, se puede evidenciar que la demanda facturada mensual no presenta cambios significativos para la reducción del consumo energético, al no existir políticas que impulsen ahorro y uso eficiente de energía. Se realiza la estimación de la demanda máxima, la energía consumida para los diferentes bloques de la institución al igual que se evalúan medidas de ahorro energético sustentables, técnicas y económicas que lleguen a optimizar el consumo de energía. Como propuesta de eficiencia se consideró el cambio de tecnología en las luminarias existentes, así como el uso de energía solar fotovoltaica, permitiendo de esta forma reducir las emisiones de CO2 logrando así que el proyecto sea viable económicamente a través de proyectos MDL (Mecanismos de Desarrollo Limpio).

Published: January 2021

This study explored the underlying thoughts of victims of school bullying through analysis of their drawings.
Eighty senior secondary students (studying in classes 9 to 11) identified as victims based on the Illinois
Victimization Scale participated in the study. Participants drew their victimization experiences and provided
elaborations of their drawings. Analysis of participants’ responses involved the framework method. Results
showed that thoughts of bullied participants were related to the (1) outcomes of being victimized (2) dealing
with the bullies, and (3) the reason for bullying. The participants evinced various thoughts related to direct or
indirect coping, victim-related reasons, and bully related reasons as gauged by their drawings. The findings
of this study were interpreted in the light of developmental-ecological framework and research. The article
indicates implications for future research and professionals to help the victims of school bullying.
Knowledge, Attitude and Practice of Menstrual Hygiene among Primary School Adolescents in Surabaya, Indonesia
Authors: Pinesa Rachma Andani  
Published: January 2021

Background: Menstruation is a normal physiological process of an adolescent female. Adolescence is a
very important transition period that requires special attention to ensure progress for all girls. Some studies
found that menstruation is taboo to be discussed and many girls just known about menstruation when
they have menarche. The genitourinary becomes more sensitive and susceptible to infection during the
menstruation period. So the appropriate menstrual hygiene practice is very important to maintain the health
of reproductive organs. This study objective is to asses the current knowledge, attitude, and practice of
primary school adolescents on menstrual hygiene management in Surabaya, Indonesia.
Method: This is a descriptive cross-sectional study that was carried out from May to June 2019 in a primary
school in Surabaya. This study was done among 78 students selected through total population sampling from
a primary school in the urban area of Surabaya.
Results: The findings showed that 66,7% of participants have good knowledge, 60,3% have a good attitude
and 79,5% have good practice regarding menstrual hygiene.
Conclusions: The majority of the participants have good knowledge, attitude and practice regarding
menstrual hygiene. Nevertheless, the knowledge, attitude, and practice of all the participants still need to
improve. The school along with the parents and health provider are expected to reinforce the health education
program about menstrual hygiene management.
Examining The Forensic Toxicity of Ricin Using Lc/Ms Techniques
Authors: Bandr Siraj Fakiha  
Published: January 2021

As one the naturally occurring toxins, Ricin is classified among the deadliest poisons available. Ricin and
Ricinus communis agglutinin (RCA120) are derived from the castor bean plant. Ricin and its related activities
can be detected using either mass spectrometric (MS) assay or Liquid Chromatography (LC). Further, the
two methods can be to differentiate ricin from RCA120 because it is less toxic of the two. The sequence of
Amino acid is identified by monitoring the active ricin using mass spectrometric. This study discusses how
LC and MS methods can be applied to quantify, detect, and differentiate ricin from RCA120 in test samples.
On the overall, the two methods were applied to tell aside ricin samples from RCA120. The study concluded
that mass spectrometry is the most efficient approach in identifying ricin from RCA120.
Gaia Gaps and the Physics of Low-mass Stars. I. The Fully Convective Boundary

Abstract
The Gaia M-dwarf gap is a significant underdensity of stars observed near M

G
= 10.2 in a color–magnitude diagram for stars within 200 pc of the Sun. It has been proposed that the gap is the manifestation of structural instabilities within stellar interiors due to nonequilibrium 3He fusion prior to some stars becoming fully convective. To test this hypothesis, we use Dartmouth stellar evolution models, MARCS model atmospheres, and simple stellar population synthesis to create synthetic M

G
, its slope in the color–magnitude diagram, and its relative prominence at bluer colors as compared to redder colors. Furthermore, corresponding overdensities of stars above the gap are reproduced by the models. While qualitatively similar, the synthetic gap is approximately 0.2 magnitudes bluer, and when this color offset is accounted for, it is 0.16 magnitudes brighter than the observed gap. Our results reveal that the Gaia M-dwarf gap is sensitive to conditions within cores of M-dwarf stars, making the gap a powerful tool for testing the physics of M-dwarf stars and potentially using M dwarfs to understand the local star formation history.

Published: January 2021

Abstract
The 1.5 Seyfert galaxy NGC 3227 has been observed by several X-ray missions. We carried out a combined analysis of the data obtained by more recent major observations of this source—two observations performed by XMM-Newton in 2000 and 2006 and six observations performed by Suzaku in 2008. A unified model, which is consistent with all eight of the observations by the two satellites with large intensity and spectral changes, was constructed. The model consists of a hard power law with the spectral index of ΓHard = 1.4–1.7, which is interpreted as the Comptonized emission from the corona above an accretion disk. In the high-flux states, an additional soft excess component dominates, which is consistent with a model with either a steeper power law with ΓSoft = 3.3–3.85 or the warm Comptonization component. These emissions from the central engine are absorbed by a partial covering material and warm absorbers. A reflection component and several emission lines are also present. We examined the relationship between the intrinsic luminosity and the absorbers’ physical parameters such as the column density, which suggests that the source expanded significantly during the bright states when the soft excess is greatly enhanced.

Abstract
The Last Journey is a large-volume, gravity-only, cosmological N-body simulation evolving more than 1.24 trillion particles in a periodic box with a side length of 5.025 Gpc. It was implemented using the HACC simulation and analysis framework on the BG/Q system Mira. The cosmological parameters are chosen to be consistent with the results from the Planck satellite. A range of analysis tools have been run in situ to enable a diverse set of science projects and, at the same time, keep the resulting data amount manageable. Analysis outputs have been generated starting at redshift z ∼ 10 to allow for construction of synthetic galaxy catalogs using a semianalytic modeling approach in postprocessing. As part of our in situ analysis pipeline, we employ a new method for tracking halo substructures, introducing the concept of subhalo cores. The production of multiwavelength synthetic sky maps is facilitated by generating particle light cones in situ, also beginning at z ∼ 10. We provide an overview of the simulation setup and generated data products; a first set of analysis results is presented. A subset of the data is publicly available.
Interstellar Extinction and Elemental Abundances
Authors: Zuo Wenbo , Li Aigen , Zhao Gang 
Published: January 2021

Abstract
Elements in the interstellar medium (ISM) exist in the form of gas or dust. The interstellar extinction and elemental abundances provide crucial constraints on the composition, size, and quantity of interstellar dust. Most of the extinction modeling efforts have assumed the total (gas and dust) abundances of the dust-forming elements—known as the “interstellar abundances,” “interstellar reference abundances,” or “cosmic abundances”—to be solar and the gas-phase abundances to be environmentally independent. However, it remains unclear whether the solar abundances are an appropriate representation of the interstellar abundances. Meanwhile, the gas-phase abundances are known to exhibit appreciable variations with local environments. Here we explore the viability of the abundances of B stars, the solar and protosolar abundances, and the protosolar abundances augmented by Galactic chemical enrichment (GCE) as an appropriate representation of the interstellar abundances by quantitatively examining the extinction and abundances of 10 interstellar sight lines for which both the extinction curves and the gas-phase abundances of all the major dust-forming elements (i.e., C, O, Mg, Si and Fe) have been observationally determined. Instead of assuming a specific dust model and then fitting the observed extinction curves, for each sight line we apply the model-independent Kramers–Kronig relation, which relates the wavelength-integrated extinction to the total dust volume, to place a lower limit on the dust depletion. This, together with the observationally derived gas-phase abundances, allows us to rule out the B-star, solar, and protosolar abundances as the interstellar reference standard and support the GCE-augmented protosolar abundances as a viable representation of the interstellar abundances.
A Survey of Three Isotopologues of CO in Molecular Clouds in the CMa OB1 Complex

Published: January 2021

Abstract
Using the Purple Mountain Observatory 13.7 m millimeter telescope at Delingha in China, we have conducted a large-scale simultaneous survey of 12CO, 13CO, and C18O (J = 1–0) toward the CMa OB1 complex with a sky coverage of 16.5 deg2 (221.5° ≤ l ≤ 227°, −2.5° ≤ b ≤ 0.5°). Emission from the CMa OB1 complex is found in the range 7 km s−1 ≤ V
LSR ≤ 25 km s−1. The large-scale structure, physical properties, and chemical abundances of the molecular clouds are presented. A total of 83 C18O molecular clumps are identified with the GaussClumps algorithm within the mapped region. We find that 94% of these C18O molecular clumps are gravitationally bound. The relationship between their size and mass indicates that none of the C18O clumps has the potential to form high-mass stars. Using a semiautomatic IDL algorithm, we newly discover 85 CO outflow candidates in the mapped area, including 23 bipolar outflow candidates. Additionally, a comparative study reveals evidence for a significant variety of physical properties, evolutionary stages, and levels of star formation activity in different subregions of the CMa OB1 complex.
Complications in the ALMA Detection of Phosphine at Venus
Authors: Akins Alex B. , Lincowski Andrew P. , Meadows Victoria S. , Steffes Paul G. 
Published: January 2021

Abstract
Recently published Atacama Large Millimeter Array (ALMA) observations suggest the presence of 20 ppb PH3 in the upper clouds of Venus. This is an unexpected result, as PH3 does not have a readily apparent source and should be rapidly photochemically destroyed according to our current understanding of Venus atmospheric chemistry. While the reported PH3 spectral line at 266.94 GHz is nearly colocated with an SO2 spectral line, the nondetection of stronger SO2 lines in the wideband ALMA data is used to rule out SO2 as the origin of the feature. We present a reassessment of wideband and narrowband data sets derived from these ALMA observations. The ALMA observations are re-reduced following both the initial and revised calibration procedures discussed by the authors of the original study. We also investigate the phenomenon of apparent spectral line dilution over varying spatial scales resulting from the ALMA antenna configuration. A 266.94 GHz spectral feature is apparent in the narrowband data using the initial calibration procedures, but this same feature cannot be identified following calibration revisions. The feature is also not reproduced in the wideband data. While the SO2 spectral line is not observed at 257.54 GHz in the ALMA wideband data, our dilution simulations suggest that SO2 abundances greater than the previously suggested 10 ppb limit would also not be detected by ALMA. Additional millimeter, submillimeter, and infrared observations of Venus should be undertaken to further investigate the possibility of PH3 in the Venus atmosphere.

Abstract
We use compiled high-precision pulsar timing measurements to directly measure the Galactic acceleration of binary pulsars relative to the solar system barycenter. Given the vertical accelerations, we use the Poisson equation to derive the Oort limit, i.e., the total volume mass density in the Galactic mid-plane. Our best-fitting model gives an Oort limit of

The error bars are currently about five times larger than kinematical estimates, but should improve in the future for this novel dynamical method. We also constrain the oblateness of the potential, finding it consistent with that expected from the disk and inconsistent with a potential dominated by a spherical halo, as is appropriate for our sample that is within a ∼kpc of the Sun. We find that current measurements of binary pulsar accelerations lead to large uncertainties in the slope of the rotation curve. We give a fitting function for the vertical acceleration a

The Formation of Bilobate Comet Shapes through Sublimative Torques
Authors: Safrit Taylor K. , Steckloff Jordan K. , Bosh Amanda S. , Nesvorny David , Walsh Kevin , Brasser Ramon , Minton David A. 
Published: January 2021

Abstract
Recent spacecraft and radar observations found that ∼70% of short-period comet nuclei, mostly Jupiter-family comets (JFCs), have bilobate shapes (two masses connected by a narrow neck). This is in stark contrast to the shapes of asteroids of similar sizes, of which ∼14% are bilobate. This suggests that a process or mechanism unique to comets is producing these shapes. Here we show that the bilobate shapes of JFC nuclei are a natural byproduct of sublimative activity during their dynamical migration from their trans-Neptunian reservoir, through the Centaur population, and into the Jupiter family. We model the torques resulting from volatile sublimation during this dynamical migration, and find that they tend to spin up these nuclei to disruption. Once disrupted, the rubble pile-like material properties of comet nuclei (tensile strengths of ∼1–10 Pa and internal friction angles of ∼35°) cause them to reform as bilobate objects. We find that JFCs likely experienced rotational disruption events prior to entering the Jupiter family, which could explain the prevalence of bilobate shapes. These results suggest that the bilobate shapes of observed comets developed recently in their history (within the past ∼1–10 Myr), rather than during solar system formation or collisions during planet migration and residency in the trans-Neptunian population.

La gestion de l’épidémie de grippe espagnole (1918-1919) : préfets et municipalités en première ligne
Authors: Vinet Freddy 
Published: January 2021

L’article revient sur la gestion par les pouvoirs publics de la pandémie de grippe dite « espagnole » de 1918-1919. Dans un contexte marqué par la fin de la Première Guerre mondiale, le pouvoir central minimise la maladie réputée bénigne. Mais en septembre 1918, face à l’augmentation des cas de complications mortels, le pouvoir central se repose sur les préfets et les municipalités pour prendre des mesures prophylactiques. Au-delà du rappel des mesures individuelles de protection, les pouvoirs locaux hésitent à prendre des mesures coercitives qui mettraient en danger la vie économique et le moral du pays éprouvé par quatre ans de guerre. Face à la méconnaissance de la maladie, au contexte de guerre et au manque de moyens et de coordination, les mesures sont tardives, mal appliquées et inefficaces. Elles ne permettent pas d’endiguer l’épidémie qui achève sa course en été 1919 après avoir touché 30 à 50 % de la population et entraîné 240000 décès en France.
