Cambiando la percepción de la belleza en la India
Authors: Seth Nitika 
Published: April 2020

¿Qué percibimos como bello y por qué? ¿Es un reflejo de los escenarios sociales, de los antecedentes económicos o quizás de nuestra historia lo que nos influye?
El trabajo investiga y analiza las razones de las percepciones estereotipadas de la belleza y discute la lenta pero evidente transformación que se está produciendo en nuestro país. en el mundo a través de las redes sociales hay un surgimiento interesante que parece haber ganado impulso en la última década. Este acceso instantáneo e ininterrumpido a todas las formas de medios ha dejado a uno atrapado en la esperanza de lograr la perfección superficial o hacia una sensación de liberación. Hay pruebas suficientes de que el contenido apresurado, homogeneizado y medio digerido que se ofrece ha llevado a una obsesión abrumadora con la apariencia de uno. Alimentarse de las inseguridades ha beneficiado a muchas organizaciones e individuos.
New Wars and Their Visual Representation: Dead Bodies without Graves/Mourne
Authors: Şur Tuncay , Yarar Betül 
Published: April 2020

This paper seeks to understand why there has been an increase in photographic images exposing military violence or displaying bodies killed by military forces and how they can freely circulate in the public without being censored or kept hidden. In other words, it aims to analyze this particular issue as a symptom of the emergence of new wars and a new regime of their visual representation. Within this framework, it attempts to relate two kinds of literature that are namely the history of war and war photography with the bridge of theoretical discussions on the real, its photographic representation, power, and violence. Rather than systematic empirical analysis, the paper is based on a theoretical attempt which is reflected on some socio-political observations in the Middle East where there has been ongoing wars or new wars. The core discussion of the paper is supported by a brief analysis of some illustrative photographic images that are served through the social media under the circumstances of war for instance in Turkey between Turkish military troops and the Kurdish militants. The paper concludes that in line with the process of dissolution/transformation of the old nation-state formations and globalization, the mechanism and mode of power have also transformed to the extent that it resulted in the emergence of new wars. This is one dynamic that we need to recognize in relation to the above-mentioned question, the other is the impact of social media in not only delivering but also receiving war photographies. Today these changes have led the emergence of new machinery of power in which the old modern visual/photographic techniques of representing wars without human beings, torture, and violence through censorship began to be employed alongside medieval power techniques of a visual exhibition of tortures and violence.

Одной из главных задач технологии выращивания томата является организация эффективного минерального питания и высокоэффективного использования системы освещения. Успешность выращивания томата обусловлена многими факторами, и температурный режим является одним из важнейших для их правильного развития. Томат довольно капризная культура, для его успешного выращивания необходимо определенное сочетание тепла и влажности, при этом требования к температурному режиму на разных этапах развития томатных кустов отличаются: прорастание семян томатов происходит при t° +20-25° C. Предотвратит вытягивание всходов, позволив им сформировать крепкую корневую систему, снижение t° до +12-15° C днем и +6-10° C ночью сроком на 1 неделю. Хорошее развитие кустам обеспечит поддержание температурного режима в дневное время на уровне t° +20-26° C и в ночное - t° +16-18° C.One of the main tasks of tomato growing technology is the organization of effective mineral nutrition and highly efficient use of the lighting system. The success of tomato cultivation is due to many factors, and the temperature regime is one of the most important for their proper development. Tomato is a rather capricious culture, for its successful cultivation a certain combination of heat and humidity is necessary, and the temperature requirements at different stages of development of tomato bushes are different: germination of tomato seeds occurs at t ° + 20-25 ° C. Prevents sprouting, allowing them to form a strong root system, decrease in t ° to + 12-15 ° C during the day and + 6-10 ° C at night for a period of 1 week. Good development of the bushes will ensure the maintenance of temperature in the daytime at t ° + 20-26 ° C and at night - t ° + 16-18 ° C.

Das ›Goldene Zeitalter‹ im modernen Spanien
Authors: Schreckenberg Stefan 
Published: April 2020

Speaking of a ›Golden Age‹ or a Siglo de Oro in reference to Spanish history, culture and literature transforms an ancient myth into a historiographical concept, which seems rather problematical, even contradictory, and at the same time, seen in a wider European context, exceptional. Nevertheless, the Siglo de Oro is still being used not only as a key term in contemporary academic works – inside and outside Spain – on the Early Modern period, but also as a highly controversial idea in political and ideological debates, especially on behalf of what may or may not be Spanish identity.
This article seeks to give a brief overview of the discussions that try to define the concept of the Siglo de Oro and to present the literary canon as well as the ideological implications linked to it. Starting in the aftermath of the epoch itself, in other words the 18th century, it focuses on the convergence of the political and aesthetical discussions that oppose the ›Two Spains‹ during the 20th century in terms of how to choose and interpret their ›classics‹. Finally, it tries to give a (necessarily incomplete) view on the actual situation, where the Golden Age myth still interferes not only in literary but also in socio-political debates.

Objective: The objective of study was to find out serum uric acid level in normal andpreeclamptic pregnant women of third trimester visiting outpatient department of obstetrics and gynecology of Bahawal Victoria Hospital, Bahawalpur.
Methodology: It was a cross sectional descriptive study conducted form July 2018 to June 2019. All primigravida women of age 18-35 years in third trimester of singleton pregnancy attending in Obstetrics and Gynecology Outpatient Department of Bahawal Victoria Hospital in study duration were included in the study. Statistical analysis was performed by using SPSS version 14. Chi-square test was performed to find the statistical difference regarding uric acid distribution between groups and ‘p’ value <0.05 was considered as a lowest level of significance.
Results: Out of total 1212 women 84.6% were normal and 15.4% had preeclampsia. In our study out of 187 preeclamptic women, 63.6% had raised serum uric acid level and out of 268 normal pregnant women uric acid level was raised in only 39.5%. Results were found statistically significant.
Conclusion: Results of our study suggest that serum uric acid level in pregnant women can be used as a useful and inexpensive marker in prediction of preeclampsia and preventive measures can be taken accordingly.
A Comparison of Properties of Quasars with and without Rapid Broad Absorption Line Variability

Published: April 2020

Abstract
We investigate the correlation between rest-frame UV flux variability of broad absorption line (BAL) quasars and their variability in BAL equivalent widths (EWs) in a various timescale from <10 days to a few years in the quasar rest frame. We use the data sets of BAL EWs taken by the Sloan Digital Sky Survey Reverberation Mapping project and photometric data taken by the intermediate Palomar Transient Factory in the g and R bands and the Panoramic Survey Telescope and Rapid Response System in grizy bands. Our results are summarized as follows: (1) the distributions of flux variability versus BAL variability show weak, moderate, or a strong positive correlation; (2) there is no significant difference in flux variability amplitudes between BAL quasars with significant short timescale EW variability (called class S1) and without (class S2); (3) in all timescales considered in this paper, the class S1 quasars show systematically larger BAL variability amplitudes than those of the class S2 quasars; and (4) there are possible correlations between BAL variability and physical parameters of the quasars such as black hole masses (moderate positive), Eddington ratios, and accretion disk temperature (strong negative) in the class S2 quasars. These results indicate that the BAL variability requires changing in the ionizing continuum and an ancillary mechanism such as variability in X-ray shielding gas located at the innermost region of an accretion disk.
Astrophysical Insights into Radial Velocity Jitter from an Analysis of 600 Planet-search Stars
Authors: Luhn Jacob K. , Wright Jason T. , Howard Andrew W. , Isaacson Howard 
Published: April 2020

Abstract
Radial velocity (RV) detection of planets is hampered by astrophysical processes on the surfaces of stars that induce a stochastic signal, or “jitter,” which can drown out or even mimic planetary signals. Here, we empirically and carefully measure the RV jitter of more than 600 stars from the California Planet Search sample on a star by star basis. As part of this process, we explore the activity–RV correlation of stellar cycles and include appendices listing every ostensibly companion-induced signal we removed and every activity cycle we noted. We then use precise stellar properties from Brewer et al. to separate the sample into bins of stellar mass and examine trends with activity and with evolutionary state. We find that RV jitter tracks stellar evolution and that in general, stars evolve through different stages of RV jitter: the jitter in younger stars is driven by magnetic activity, while the jitter in older stars is convectively driven and dominated by granulation and oscillations. We identify the “jitter minimum”—where activity-driven and convectively driven jitter have similar amplitudes—for stars between 0.7 and 1.7 M
⊙ and find that more-massive stars reach this jitter minimum later in their lifetime, in the subgiant or even giant phases. Finally, we comment on how these results can inform future RV efforts, from prioritization of follow-up targets from transit surveys like TESS to target selection of future RV surveys.
Heating and Eruption of a Solar Circular-ribbon Flare
Authors: Lee Jeongwoo , Karpen Judith T. , Liu Chang , Wang Haimin 
Published: April 2020

Abstract
We studied a circular-ribbon flare, SOL2014-12-17T04:51, with emphasis on its thermal evolution as determined by the differential emission measure (DEM) inversion analysis of the extreme ultraviolet (EUV) images of the Atmospheric Imaging Assembly instrument on board the Solar Dynamics Observatory. Both temperature and emission measure start to rise much earlier than the flare, along with an eruption and formation of a hot halo over the fan structure. In the main flare phase, another set of ribbons forms inside the circular ribbon, and expands as expected for ribbons at the footpoints of a postflare arcade. An additional heating event further extends the decay phase, which is also characteristic of some eruptive flares. The basic magnetic configuration appears to be a fan–spine topology, rooted in a minority-polarity patch surrounded by majority-polarity flux. We suggest that reconnection at the null point begins well before the impulsive phase, when the null is distorted into a breakout current sheet, and that both flare and breakout reconnection are necessary in order to explain the subsequent local thermal evolution and the eruptive activities in this confined magnetic structure. Using local DEMs, we found a postflare temperature increase inside the fan surface, indicating that the so-called EUV late phase is due to continued heating in the flare loops.

Published: April 2020

Abstract
We present timing and time-integrated spectral analysis of 127 bursts from SGR J1935+2154. These bursts were observed with the Gamma-ray Burst Monitor on the Fermi Gamma-ray Space Telescope and the Burst Alert Telescope on the Neil Gehrels Swift Observatory during the source’s four active episodes from 2014 to 2016. This activation frequency makes SGR J1935+2154 the most burst prolific transient magnetar. We find the average duration of all the detected bursts to be much shorter than the typical, anticipated value. We fit the burst time-integrated spectra with two blackbody functions, a Comptonized model and three other simpler models. Bursts from SGR J1935+2154 exhibit similar spectral properties to other magnetars, with the exception of the power-law index from the Comptonized model, which correlates with burst fluence. We find that the durations and both blackbody temperatures of the bursts have significantly evolved across the four active episodes. We also find that the burst time history exhibits two trends, which are strongly correlated with the decay of the persistent emission in each outburst.

Abstract
Chandra obtained two High Energy Transmission Grating spectra of the stellar-mass black hole GRO J1655−40 during its 2005 outburst, revealing a rich and complex disk wind. Soon after its launch, the Neil Gehrels Swift Observatory began monitoring the same outburst. Some X-ray Telescope (XRT) observations were obtained in a mode that makes it impossible to remove strong Mn calibration lines, so the Fe Kα line region in the spectra was previously neglected. However, these lines enable a precise calibration of the energy scale, facilitating studies of the absorption-dominated disk wind and its velocity shifts. Here we present fits to 15 Swift/XRT spectra, revealing variability and evolution in the outflow. The data strongly point to a magnetically driven disk wind: both the higher-velocity (e.g.,

) and lower-velocity (e.g.,

) wind components are typically much faster than is possible for thermally driven outflows (

), and photoionization modeling yields absorption radii that are two orders of magnitude below the Compton radius that defines the typical inner extent of thermal winds. Moreover, correlations between key wind parameters yield an average absorption measure distribution that is consistent with magnetohydrodynamic wind models. We discuss our results in terms of recent observational and theoretical studies of black hole accretion disks and outflows, as well as future prospects.
Constraint on the Ejecta Mass for Black Hole–Neutron Star Merger Event Candidate S190814bv
Authors: Kawaguchi Kyohei , Shibata Masaru , Tanaka Masaomi 
Published: April 2020

Abstract
We derive the upper limit to the ejecta mass of S190814bv, a black hole–neutron star (BH–NS) merger candidate, through radiative transfer simulations for kilonovae with realistic ejecta density profiles, as well as detailed opacity and heating rate models. The limits to the ejecta mass strongly depend on the viewing angle. For the face-on observations (≤45°), the total ejecta mass should be smaller than 0.1 M
⊙ for the average distance of S190814bv (D = 267 Mpc), while a larger mass is allowed for the edge-on observations. We also derive the conservative upper limits of the dynamical ejecta mass to be 0.02, 0.03, and 0.05 M
⊙ for the viewing angles ≤20°, ≤50°, and ≤90°, respectively. We show that an iz-band observation deeper than 22 mag within 2 days after the gravitational-wave trigger is crucial to detect a kilonova with a total ejecta mass of 0.06 M
⊙ at a distance of D = 300 Mpc. We also show that a strong constraint on the NS mass–radius relation can be obtained if future observations put an upper limit of 0.03 M
⊙ on the dynamical ejecta mass for a BH–NS event with a chirp mass smaller than ≲3 M
⊙ and effective spin larger than ≳0.5.
Gamma-Ray Flares in the Long-term Light Curve of 3C 454.3
Authors: Das Avik Kumar , Prince Raj , Gupta Nayantara 
Published: April 2020

Abstract
3C 454.3 is frequently observed in the flaring state. The long-term light curve of this source has been analyzed with 9 yr (2008 August–2017 July) of data from the Fermi-LAT detector. We have identified five flares and one quiescent state. The flares have substructures with many peaks during the flaring phase. We have estimated the rise and decay time of the flares and compared with flares of other similar sources. The modeling of gamma-ray spectral energy distributions shows in most cases that a log-parabola function gives the best fit to the data. We have done time-dependent leptonic modeling of two of the flares, for which simultaneous multiwavelength data are available. These two long-lasting flares, Flare-2A and Flare-2D, continued for 95 and 133 days, respectively. We have used the average values of Doppler factor, injected luminosity in electrons, size of the emission region, and the magnetic field in the emission region in modeling these flares. The emission region is assumed to be in the broad-line region in our single-zone model. The energy losses (synchrotron, synchrotron self-Compton, external Compton) and escape of electrons from the emission region have been included while doing the modeling. Although the total jet powers required to model these flares with the leptonic model are higher compared to other sources, they are always found to be lower than the Eddington luminosity of 3C 454.3. We also select some flaring peaks and show that the time variation of the Doppler factor or the injected luminosity in electrons over short timescales can explain their light curves.
