ABSTRACTGreen mustard (Brassica rapa L. var. Tosakan) is a vegetable commodity that has been widely cultivated. Community needs for green mustard are increasing, so that the demand for green mustard consumers is worth developed. An important factor in crop cultivation that supports the success of mustard greens production is fertilization. Study aims to examine the growth response of green mustard plants (Brassica rapa L. var. Tosakan) due to the administration of PGPR (Plant Growth-romoting Rhizobacteria) combined with compost or NPK fertilizer. This study consisted of five treatments that were repeated five times: P0 (farmland as a control), P1 (garden land plus PGPR application), P2 (garden land, compost plus PGPR application), P3 (garden land plus NPK fertilizer with granting PGPR), P4 (garden land plus NPK). The results of the study showed that PGPR could generally increase the growth of green mustard better than controls. The combination of PGPR that provided the best results was the PGPR and NPK fertilizer combination.Keywords: Green mustard, PGPR, Compost fertilizer, NPK fertilizer.

Abstract
An aluminum oxide (Al2O3) passivation film that prevents the oxidation of a sputtered and sulfurized molybdenum disulfide (MoS2) film was investigated for an enhancement of the Hall-effect mobility. A remarkably high Hall-effect electron mobility value of 100 cm2 V−1 s−1 was achieved using 3 nm passivation film, as compared to 25 cm2 V−1 s−1 for an as-deposited MoS2 film, because sulfurization is able to be yielded even through the Al2O3 film into the MoS2 film.

Introducción: La osteoporosis es una enfermedad que se incrementa conforme nuestra población envejece; esta se asocia a mayor riesgo de fracturas por fragilidad, conllevando a pérdida de la independencia, dolor crónico e incluso la muerte. Con el fin de evitar dichas complicaciones, es importante caracterizar la población con diagnóstico de fractura por fragilidad e identificar si se está realizando un adecuado tamizaje y abordaje del paciente con riesgo o diagnóstico de osteoporosis.
Materiales y métodos: Estudio prospectivo realizado en pacientes ingresados con fractura por fragilidad en un hospital de alta complejidad, en el periodo entre marzo-septiembre del 2018. Se realizó una caracterización según variables clínico-sociodemográficas y se aplicó criterios de tamización según diferentes guías a fin de determinar si se está realizando un adecuado tamizaje y abordaje del paciente con fractura por fragilidad.
Resultados: Se identificaron 70 pacientes con fracturas por fragilidad, la edad promedio fue de 80,01 ± 10,73 años. Se encontró que el 81,43% de los pacientes había sido evaluado por médico general pero tan solo el 50% había sido educado sobre prevención de caídas. Además, el 97,14%, 95,71% y 90,0% de los pacientes cumplían criterios de tamización para osteoporosis según las guías NOF, ISCD y OSC respectivamente y solo 11,43% habían sido tamizados.
Conclusión: Las fracturas por fragilidad son frecuentes en nuestro medio, sin embargo, los tiempos de atención e intervención son lentos y los esfuerzos en prevención tanto primaria como secundaria están siendo insuficientes.

Published: August 2020

Introducción: el síndrome de Cushing (SC) es un grupo de signos y síntomas causados por la exposición crónica al exceso de glucocorticoides. El uso de fármacos con glucocorticoides es la causa más frecuente, pero algunos productos vendidos como suplementos nutricionales o medicamentos naturistas para el control de los dolores articulares pueden contenerlos de forma oculta, lo cual dificulta el enfoque diagnóstico.
Presentación del caso: paciente de 40 años con signos clínico típicos de síndrome de Cushing con resultados discordantes en las pruebas diagnósticas para identificar su origen. Finalmente se logra establecer que el paciente consumía de forma crónica un producto “naturista” conocido como Artrin®, el cual fue analizado en el laboratorio de la institución con resultados positivos para cortisol.
Conclusión: la exposición crónica a glucocorticoides exógenos, ya sea subrepticia, desconocida o prescrita, causa SC y debe distinguirse tempranamente de las formas endógenas para evitar la realización de pruebas diagnósticas y tratamientos inadecuados.

Published: August 2020

Introducción: la hidroxicloroquina se ha venido postulando en estos tiempos de pandemia como posible tratamiento eficaz frente a COVID-19. Esto ya que se ha demostrado por expertos chinos su capacidad para inhibir la replicación viral usando distintos mecanismos. En este momento es de vital importancia tener conocimiento acerca de las últimas investigaciones y ensayos clínicos en lo que respecta a un esquema de tratamiento efectivo que ayude a un mejor manejo de pacientes con infección por SARS-CoV-2.
Objetivo: presentar la información disponible sobre el uso de hidroxicloroquina como opción de manejo para pacientes infectados por SARS-CoV-2. Material y métodos: se realizó una revisión siguiendo el marco metodológico sugerido por Arksey y O’Malley. Las bases de datos utilizadas fueron: PubMed, MedLine, Lilacs, Scopus, Clinical Trials, Cochrane y CNKI. Se incluyeron únicamente textos en español e inglés, finalmente se realizó una caracterización y resumen de los estudios pertinentes para esta revisión.
Resultados: se incluyeron en la revisión 87 artículos académicos incluyendo estudios experimentales y no experimentales; todos con evidencia sobre el uso de hidroxicloroquina en COVID-19.
Conclusiones: A la fecha no hay información científica disponible que sustente y tenga la suficiente evidencia para soportar el uso de la hidroxicloroquina como tratamiento farmacológico en la pandemia actual. Dos ensayos clínicos aleatorizados se contradicen en cuanto a la efectividad de la hidroxicloroquina; sin embargo, ambos comparten errores metodológicos y tamaños de muestra limitados; y un único ensayo no aleatorizado con los mismos errores demuestra efectividad de la hidroxicloroquina. En cuanto al perfil de seguridad se cuenta con información que evidencia una menor tasa de efectos adversos de la hidroxicloroquina frente a la cloroquina por lo que se preferiría su uso en caso de demostrar efectividad frente a COVID-19. Existen varios ensayos clínicos aleatorizados en curso que se espera esclarezcan las dudas que surgen al revisar la literatura

Abstract
We report distinctive core profiles in the strongest optical helium line, He i
λ5876, from high-resolution high-sensitivity observations of spectral type DB white dwarfs. By analyzing a sample of 40 stars from Keck/HIRES and VLT/UVES, we find the core appearance to be related to the degree of hydrogen and heavy element content in the atmosphere. New Ca K-line measurements or upper limits are reported for about half the sample stars. He i
λ5876 emission cores with a self-reversed central component are present for those stars with relatively low hydrogen abundance, as well as relatively low atmospheric heavy element pollution. This self-reversed structure disappears for stars with higher degrees of pollution and/or hydrogen abundance, giving way to a single absorption core. From our model atmospheres, we show that the self-reversed emission cores can be explained by temperature inversions in the upper atmosphere. We propose that the transition to a single absorption core is due to the additional opacity from hydrogen and heavy elements that inhibits the temperature inversions. Our current models do not exactly match the effective temperature range of the phenomenon or the amplitude of the self-reversed structure, which is possibly a result of missing physics such as 3D treatment, convective overshoot, and/or non-LTE effects. The He i
λ5876 line structure may prove to be a useful new diagnostic for calibrating temperature profiles in DB atmosphere models.
The Age Distribution of Stars in the Milky Way Bulge
Authors: Sit Tawny , Ness M. K. 
Published: August 2020

Abstract
The age and chemical characteristics of the Galactic bulge link to the formation and evolutionary history of the Galaxy. Data-driven methods and large surveys enable stellar ages and precision chemical abundances to be determined for vast regions of the Milky Way, including the bulge. Here, we use the data-driven approach of The Cannon, to infer the ages and abundances for 125,367 stars in the Milky Way, using spectra from Apache Point Observatory Galaxy Evolution Experiment (apogee) DR14. We examine the ages and metallicities of 1654 bulge stars within

. We focus on fields with b < 12°, and out to longitudes of l < 15°. We see that stars in the bulge are about twice as old (τ = 8 Gyr), on average, compared to those in the solar neighborhood (τ = 4 Gyr), with a larger dispersion in [Fe/H] (≈0.38 compared to 0.23 dex). This age gradient comes primarily from the low-α stars. Looking along the Galactic plane, the very central field in the bulge shows by far the largest dispersion in [Fe/H] (σ
[Fe/H] ≈ 0.4 dex) and line-of-sight velocity (σ
vr ≈ 90 km s−1), and simultaneously the smallest dispersion in age. Moving out in longitude, the stars become kinematically colder and less dispersed in [Fe/H], but show a much broader range of ages. We see a signature of the X-shape within the bulge at a latitude of b = 8°, but not at b = 12°. Future apogee and other survey data, with larger sampling, affords the opportunity to extend our approach and study in more detail, to place stronger constraints on models of the Milky Way.

Abstract
Quasars are the most luminous of active galactic nuclei, and are perhaps responsible for quenching star formation in their hosts. The Stripe 82X catalog covers 31.3 deg2 of the Stripe 82 field, of which the 15.6 deg2 covered with XMM-Newton is also covered by Herschel/SPIRE. We have 2500 X-ray detected sources with multiwavelength counterparts, and 30% of these are unobscured quasars, with L
X > 1044 erg s−1 and M

B
< −23. We define a new population of quasars that are unobscured, have X-ray luminosities in excess of 1044 erg s−1, have broad emission lines, and yet are also bright in the far-infrared, with a 250 μm flux density of S
250 > 30 mJy. We refer to these Herschel-detected, unobscured quasars as “cold quasars.” A mere 4% (21) of the X-ray- and optically selected unobscured quasars in Stripe 82X are detected at 250 μm. These cold quasars lie at z ∼ 1–3, have L
IR > 1012
L
⊙, and have star formation rates (SFRs) of ∼200–1400 M
⊙ yr−1. Cold quasars are bluer in the mid-IR than the full quasar population, and 72% of our cold quasars have WISE W3 < 11.5 [Vega], while only 19% of the full quasar sample meets this criteria. Crucially, cold quasars have on average ∼nine times as much star formation as the main sequence of star-forming galaxies at similar redshifts. Although dust-rich, unobscured quasars have occasionally been noted in the literature before, we argue that they should be considered as a separate class of quasars due to their high SFRs. This phase is likely short-lived, as the central engine and immense star formation consume the gas reservoir. Cold quasars are type-1 blue quasars that reside in starburst galaxies.

Abstract
We used the mark weighted correlation functions (MCFs), W(s), to study the large-scale structure of the universe. We studied five types of MCFs with the weighting scheme ρ

α
, where ρ is the local density, and α is taken as −1, −0.5, 0, 0.5, and 1. We found that different MCFs have very different amplitudes and scale dependence. Some of the MCFs exhibit distinctive peaks and valleys that do not exist in the standard correlation functions. Their locations are robust against the redshifts and the background geometry; however, it is unlikely that they can be used as “standard rulers” to probe the cosmic expansion history. Nonetheless, we find that these features may be used to probe parameters related with the structure formation history, such as the values of σ
8 and the galaxy bias. Finally, after conducting a comprehensive analysis using the full shapes of the W(s)s and W
Δs
(μ)s, we found that combining different types of MCFs can significantly improve the cosmological parameter constraints. Compared with using only the standard correlation function, the combinations of MCFs with α = 0, 0.5, 1 and α = 0, −1, −0.5, 0.5, 1 can improve the constraints on Ω
m
and w by ≈30% and 50%, respectively. We find highly significant evidence that MCFs can improve cosmological parameter constraints.
Late-time Circumstellar Interaction of SN 2017eaw in NGC 6946
Authors: Weil Kathryn E. , Fesen Robert A. , Patnaude Daniel J. , Milisavljevic Dan 
Published: August 2020

Abstract
SN 2017eaw, the tenth supernova observed in NGC 6946, was a normal Type II-P supernova with an estimated 11–13 M
⊙ red supergiant progenitor. Here we present nebular-phase spectra of SN 2017eaw at +545 and +900 days post-max, extending approximately 50–400 days past the epochs of previously published spectra. While the +545 day spectrum is similar to spectra taken between days +400 and +493, the +900 day spectrum shows dramatic changes both in spectral features and emission-line profiles. The Hα emission is flat-topped and boxlike with sharp blue and red profile velocities of ≃−8000 and +7500 km s−1. These late-time spectral changes indicate strong circumstellar interaction with a mass-loss shell, expelled ∼1700 yr before explosion. SN 2017eaw’s +900 day spectrum is similar to those seen for SN 2004et and SN 2013ej observed 2–3 yr after explosion. We discuss the importance of late-time monitoring of bright SNe II-P and the nature of presupernova mass-loss events for SN II-P evolution.
Hunting for Runaways from the Orion Nebula Cluster
Authors: Farias Juan P. , Tan Jonathan C. , Eyer Laurent 
Published: August 2020

Abstract
We use Gaia DR2 to hunt for runaway stars from the Orion Nebula Cluster (ONC). We search a region extending 45° around the ONC and out to 1 kpc to find sources that have overlapped in angular position with the cluster in the last ∼10 Myr. We find ∼17,000 runaway/walkaway candidates that satisfy this 2D traceback condition. Most of these are expected to be contaminants, e.g., caused by Galactic streaming motions of stars at different distances. We thus examine six further tests to help identify real runaways, namely: (1) possessing young stellar object (YSO) colors and magnitudes based on Gaia optical photometry; (2) having IR excess consistent with YSOs based on 2MASS and Wide-field Infrared Survey Explorer photometry; (3) having a high degree of optical variability; (4) having closest approach distances well-constrained to within the cluster half-mass radius; (5) having ejection directions that avoid the main Galactic streaming contamination zone; and (6) having a required radial velocity (RV) for 3D overlap of reasonable magnitude (or, for the 7% of candidates with measured RVs, satisfying 3D traceback). Thirteen sources, not previously noted as Orion members, pass all these tests, while another twelve are similarly promising, except they are in the main Galactic streaming contamination zone. Among these 25 ejection candidates, ten with measured RVs pass the most restrictive 3D traceback condition. We present full lists of runaway/walkaway candidates, estimate the high-velocity population ejected from the ONC, and discuss its implications for cluster formation theories via comparison with numerical simulations.
