Abstract
We present constraints on the dust continuum flux and inferred gas content of a gravitationally lensed massive quiescent galaxy at z = 1.883 ± 0.001 using AzTEC 1.1 mm imaging with the Large Millimeter Telescope. MRG-S0851 appears to be a prototypical massive compact quiescent galaxy, but evidence suggests that it experienced a centrally concentrated rejuvenation event in the last 100 Myr. This galaxy is undetected in the AzTEC image but we calculate an upper limit on the millimeter flux and use this to estimate the H2 mass limit via an empirically calibrated relation that assumes a constant molecular-gas-to-dust ratio of 150. We constrain the 3σ upper limit of the H2 fraction from the dust continuum in MRG-S0851 to be

. MRG-S0851 has a low gas fraction limit with a moderately low sSFR owing to the recent rejuvenation episode, which together result in a relatively short depletion time of <0.6 Gyr if no further H2 gas is accreted. Empirical and analytical models both predict that we should have detected molecular gas in MRG-S0851, especially given the rejuvenation episode; this suggests that cold gas and/or dust is rapidly depleted in at least some early quiescent galaxies.

Abstract
We report the first detection of a hydroxyl radical (OH) emission signature in the planetary atmosphere outside the solar system, in this case, in the dayside of WASP-33b. We analyze high-resolution near-infrared emission spectra of WASP-33b taken using the InfraRed Doppler spectrograph on the 8.2 m Subaru telescope. The telluric and stellar lines are removed using a detrending algorithm, SysRem. The residuals are then cross-correlated with OH and H2O planetary spectrum templates produced using several different line lists. We check and confirm the accuracy of OH line lists by cross-correlating with the spectrum of GJ 436. As a result, we detect the emission signature of OH at K
p of

km s−1 and v
sys of −0.3

km s−1 with a signal-to-noise ratio (S/N) of 5.4 and a significance of 5.5σ. Additionally, we marginally detect H2O emission in the H-band with an S/N of 4.0 and a significance of 5.2σ using the POKAZATEL line list. However, no significant signal is detected using the HITEMP 2010, which might be due to differences in line positions and strengths, as well as the incompleteness of the line lists. Nonetheless, this marginal detection is consistent with the prediction that H2O is mostly thermally dissociated in the upper atmosphere of the ultra-hot Jupiters. Therefore, along with CO, OH is expected to be one of the most abundant O-bearing molecules in the dayside atmosphere of ultra-hot Jupiters and should be considered when studying their atmospheres.
Pure Density Evolution of the Ultraviolet Quasar Luminosity Function at 2 ≲ z ≲ 6
Authors: Kim Yongjung , Im Myungshin 
Published: March 2021

Abstract
The quasar luminosity function (QLF) shows the active galactic nucleus (AGN) demography as a result of the combination of the growth and the evolution of black holes, galaxies, and dark matter halos along the cosmic time. The recent wide and deep surveys have improved the census of high-redshift quasars, making it possible to construct reliable ultraviolet (UV) QLFs at 2 ≲ z ≲ 6 down to M
1450 = − 23 mag. By parameterizing these up-to-date observed UV QLFs that are the most extensive in both luminosity and survey area coverage at a given redshift, we show that the UV QLF has a universal shape and its evolution can be approximated by a pure density evolution (PDE). In order to explain the observed QLF, we construct a model QLF employing the halo mass function, a number of empirical scaling relations, and the Eddington ratio distribution. We also include the outshining of AGN over its host galaxy, which made it possible to reproduce a moderately flat shape of the faint end of the observed QLF (slope of ∼ − 1.1). This model successfully explains the observed PDE behavior of UV QLF at z > 2, meaning that the QLF evolution at high redshift can be understood under the framework of halo mass function evolution. The importance of the outshining effect in our model also implies that there could be a hidden population of faint AGNs (M
1450 ≳ − 24 mag), which are buried under their host galaxy light.
La constitution du travail : à propos d’un concept wébérien méconnu
Authors: Coutu Michel 
Published: March 2021

Les travaux de jeunesse de Max Weber consacrés aux conditions du travail agricole en Allemagne à l’est de l’Elbe demeurent peu connus. Leur antériorité par rapport à la sociologie wébérienne proprement dite, la primauté apparente des jugements de valeur en leur sein et un caractère historique fortement daté peuvent expliquer ce manque d’intérêt. L’auteur adopte ici résolument le point de vue contraire. En particulier, même si cette terminologie n’apparaît pas encore, Weber y observe avec rigueur des processus de rationalisation notamment économique (passage du domaine patriarcal à l’exploitation capitaliste) et juridique (de la tenure féodale au contrat de travail « libre ») dont il s’agit d’explorer les multiples tensions et antinomies. Par ailleurs, si l’on s’attache au concept central de ces études, celui de la « constitution du travail », la notion présente un intérêt indiscutable – et universel – pour l’étude de la dynamique des rapports de travail dans le cadre de la modernité. Il paraît toutefois indispensable de réinterpréter la notion en tenant compte des travaux de maturité de Weber, notamment de sa sociologie du droit telle qu’elle se dégage en particulier d’Économie et société.

Digitalization of the economy is a key priority for Russia today, which makes the problem stated herein relevant. Personal motivations, values, mor-als, and ethics are of increasing importance. In this regard, project, flexible, and soft skills are coming to the fore; these include digital skills such as the ability to confidently, effectively, critically, and safely pick and apply in-formation and communication technologies in various aspects of life. Re-search and experimentation skills, being an integral part of engineering cul-ture and thinking, stay relevant, too.
The purpose of the study is to prove the effectiveness of developing digi-tal competencies and engineering thinking in children and young people dur-ing the Digital Summer project, developed as part of a grant for conducting thematic sessions in advanced areas of discrete mathematics, informatics, and digital technologies.
In the course of the study, effectiveness was assessed by mathematical processing of the results of questionnaires and surveys of session partici-pants. The results of the study allow concluding that it is possible to translate the experience gained into the system of working with children and youth.
« Où est la frontière? »
Authors: Pârlea Vanezia 
Published: March 2021

À l’époque des redéfinitions de l’interculturalité et des migrations mondialisées, une déconstruction de la notion de frontière comme celle proposée par Isabelle Eberhardt – que le présent article s’emploie à analyser – s’avère féconde, en préfigurant l’essor des « littératures migrantes » d’aujourd’hui. Fruit de multiples déplacements – identitaires, spatiaux, interculturels et idéologiques qui, bien que consubstantiels, seront analysés séparément, selon leur spécificité – la pensée eberhardtienne, empreinte de la logique d’une hybridation continuelle, en vient ainsi à construire une perspective dynamique de la frontière, envisagée non plus comme coupure ou barrière, mais comme pont, comme passage entre les cultures. En même temps, loin de toute idéalisation, cette sagesse de l’hybridité léguée par Isabelle Eberhardt n’est pas sans rappeler les écueils de la transculturalité qu’un être hybride, « déplacé », se doit d’affronter.
Égypte, terre du Nil (1939) de Fernand Leprette : exemplarité du livre d’un intellectuel au service de deux pays, l’Égypte et la France
Authors: Lançon Daniel 
Published: March 2021

L’étude porte sur Égypte, terre du Nil (1939) de Fernand Leprette, inspecteur français auprès du Ministère de l’Instruction Publique égyptien, poète, conférencier, mentor des écrivains francophones d’Égypte. Ce récit de vingt années de séjour en Égypte montre un écrivain humaniste, sensible, altruiste, porte-parole des hommes et des femmes du peuple, surtout des campagnes, passionné par sa « seconde patrie. » Le livre de cet intellectuel au service de deux pays, l’Égypte nation nouvelle se réappropriant sa personnalité orientale tout en s’ouvrant aux modernités européennes et la France, est le témoignage littéraire exemplaire d’un décentrement ayant abouti à l’accueil d’une altérité devenue intérieure.
« Marcher le plus longtemps possible ».Fantasmes et expériences du déplacement dans la poésie d’Iman Mersal (Égypte)
Authors: Dampierre-Noiray Ève de 
Published: March 2021

Prenant comme perspective de départ la place occupée par le poème « Le Seuil » dans l’œuvre de la poétesse égyptienne Iman Mersal (née en 1966), texte phare à la fois par sa situation dans le parcours d’écriture, par sa portée poétique et politique, et par ses rapports structurels avec les images et motifs de l’ensemble de l’œuvre, l’article s’intéresse à la pensée du déplacement et à ses images, au seuil de l’expérience de l’émigration. Il tente de montrer par quels moyens poétiques est mise en scène une crise du lieu et du langage qui projette le sujet lyrique et le lecteur dans l’obsession du déplacement (errance frénétique dans l’espace autochtone, fatalité du départ à l’étranger), dans une impossible sédentarité ici comme là-bas, et dans une amertume politique, fantôme qui hante celui ou celle qui peut se définir comme un individu postcolonial.
Risk of chronic kidney disease and end-stage renal disease in patients with psoriasis
Authors: Yang Shang-Feng , Chen Ting-Hao , Tsai Shin-Hung , Chen Pei-En , Chi Ching-Chi , Tung Tao-Hsin 
Published: March 2021

Background:
Previous studies showed a higher risk of renal disease among patients with psoriasis; however, this association has been inconsistent.

Objectives:
This study aimed to carry out a comparison in the probability from suffering renal diseases—including chronic kidney disease (CKD), end-stage renal disease (ESRD), IgA nephropathy (IgAN), glomerular disease (GD), and those resulting in death caused by other renal diseases—in patients with psoriasis.

Methods:
The systematic review and meta-analysis was conducted to identify cohort studies with reported hazard ratios (HRs) and a 95% confidence intervals (CIs) for the renal outcomes among patients with psoriasis. The meta-analysis was analyzed with the random-effects modeling and was further stratified by psoriasis severity.

Results:
Three studies were included. Compared to controls without psoriasis, patients with psoriasis had increased risks of CKD (HR: 1.53; 95% CI: 1.20–1.96) and ESRD (HR: 1.24, 95% CI: 1.06–1.46). The risks of CKD (HR: 1.91, 95% CI: 1.78–2.05) and ESRD (HR: 2.72, 95% CI: 1.71–4.34) were increased in servere psoriasis patients. Due to substantial heterogeneity across enrolled studies (I
2 = 95%), the risk of CKD in mild psoriasis was insignificant (HR: 1.14, 95% CI 0.87–1.48). Two studies identified severe psoriasis were related to higher risks of IgAN and GD, whereas one study found that mild psoriasis was associated with an increased risk of death from renal disease.

Conclusion:
Patients with severe psoriasis have a higher risk of incident CKD, ESRD, and GD. However, we only identified two cohort studies that compared the risk of IgAN and GD in psoriasis patients to general populations. It is difficult to conclude that severe psoriasis was associated with higher risks of IgAN and GD. For mild psoriasis, the association with renal disease was less consistent.
A population-based observational morphologic measurements of anatomic landmarks in maxillary and mandibular molar
Authors: Agarwal Esha , Nikhil Vineeta 
Published: March 2021

Aim:
The aim of this study is to study the morphological measurements of external and internal anatomic landmarks in human maxillary and mandibular molars and their correlation with critical pulp chamber morphology.

Materials and Methods:
A total of 200 mandibular and maxillary molar teeth of patients were evaluated. Teeth whose pulp chamber were not violated by caries, restoration, fracture crown, and those having closed apex were included in the study. Teeth were subjected to radiovisiography of bitewing projection and imaging tool was utilized for measuring-A: Distance from the pulp chamber floor to the furcation, B: Distance from the pulp chamber ceiling to the furcation, C: Distance from the buccal cusp tip to the furcation, D: Distance from the buccal cusp to the floor of the pulp chamber, E: Distance from the buccal cusp to the ceiling of pulp chamber, and F: Pulp chamber height. Differences in the measurements were examined using the Student's t-test and Pearson correlations. All results were considered statistically significant if P < 0.05.

Results:
There were significant differences found among the various measurements between young and old population groups (P < 0.05). The highest percentage variance was found for the height of the pulp chamber (P < 0.001).

Conclusions:
The knowledge of pulp chamber morphology should be integrated with preoperative radiograph and intraoperative tactile perception during endodontic access preparation.

Published: March 2021

Aim:
The aim of this study was to compare the shaping ability of four different single-file systems in severely curved mesiobuccal root canals in extracted human mandibular first molars.

Materials and Methods:
Sixty extracted intact human mandibular first molars with at least one curved mesial root were collected and used for the study. The study samples (n = 60) were divided into four experimental groups (n = 15 each): WaveOne (WO) (Group I), WaveOne Gold (WOG) (Group II), OneShape (Group III), and F360 (Group IV). The working length was established. All the study samples were prepared with respective file systems according to manufacturer's instructions. Pre- and postinstrumentation radiographs were taken and images were transferred to AutoCAD 2016 to determine the radius of curvature of each root canal. The canal curvature was assessed as a difference between before and after instrumentation to determine canal straightening. The data obtained were subjected to statistical analysis using SPSS version 20.0.

Results:
The pre- and postinstrumentation readings were compared using one-sample t-test, and difference was found to be statistically significant (P < 0.05). The mean difference in root curvature was estimated by pre- and postinstrumentation readings. According to mean change in the root curvature, the order determined was Group IV < III < II < I. Intergroup comparison was conducted using ANOVA statistical analysis, and it was found to be statistically significant.

Conclusion:
WOG and WO reciprocating files showed a marked tendency to straighten the severely curved canals, whereas F360 and OneShape continuous files maintained the original canal curvatures well.

Aim:
This study aimed to evaluate and compare the antimicrobial efficacy of asphaline temp, triple antibiotic paste (TAP), and Ultracal Xs against Enterococcus faecalis – An in vitro study.

Materials and method:
A hundred and twenty freshly extracted, single-rooted human permanent teeth were instrumented and autoclaved. Samples were inoculated with the pure culture of E. faecalis and incubated. After incubation, colony-forming units (CFUs) were recorded before medication. Each group was further divided into three subgroups containing ten samples each for days – 1 day, 5 days, and 7 days. Group A – Asphaline Temp; Group B – TAP; Group C – Calcium hydroxide; and Group D – Normal saline (Control). The various time interval bacterial (CFU) within the group were compared by the Analysis of Variance followed by Tukey's Post hoc test.

Results:
The greater antimicrobial effects were observed in the samples treated with Asphaline temp (P < 0.005). No statistical antimicrobial difference was found between Asphaline temp and TAP.

Conclusion:
Asphaline temp demonstrated significant antimicrobial effectiveness against E. faecalis.
