Globally diabetes mellitus (T2DM) is a burning issue. Prediction of global estimation that the proportion of diabetes with adult will increase 69% for the year 2030. Hans Selye, the Canadian physiologist, was the first scientist to study the effects of psychological stress on the human body in 1936.Diabetic patients are in a state of high oxidative stress which leading to impaired glucose homeostasis, insulin insufficiency, and other complications.: A randomized controlled trial was conducted to see the effect of the vitamin D supplementation on oxidative stress in vitamin D deficientT2DM patients. In this study, a total of 124 T2DM patients were randomly enrolled, among them Treatment group 61 and placebo 63. In treatment group received 20,000IU vitamin D every 5thDay for three months in addition to regular treatment. Analysis of fasting   plasma glucose (FPG), Vitamin D 25(OH)2, malondialdehyde (MDA) and superoxide dismutase (SOD) have been estimated both at the time of study recruitment, at 6th weeks and after 12-weeks of vitamin D supplementation (endline). Present study showed after vitamin D supplementation, baseline mean FBG gradually significantly (P<0.001) decreased at the end line in treatment group as compared to placebo. All biochemical indices by P- trend like FBG, vitamin D, MDA and SOD were significantly different (P<0.05). Whenever, consider between groups vitamin D increased (P<0.05) and FBG decreased significantly (P<0.05) in treatment group as compared to placebo. However, no significant impact on socio-demography variables, vitamin D and Stress-related characteristics between treatment and control groups after vitamin D supplementation as those variables are somewhat independent (p>0.05) both at baseline and end line. The results were considered significant at P<0.05. The statistical calculations were done using SPSS version 26 software. A strong positive co-relation between diabetes and oxidative stress were observed in this study and showed beneficial impact of vitamin D supplementation to reduce oxidative stress those who were vitamin D deficient.

Published: January 2023

O capital humano é considerado um dos principais fatores para o desenvolvimento humano e econômico. Neste sentido, diversos países buscam, por meio de uma série de indicadores, averiguar continuamente a realidade educacional de seus habitantes. No Brasil, o Índice de Desenvolvimento Humano Municipal -Educação (IDHM-Educação) e o Índice Firjan de Desenvolvimento MunicipalEducação (IFDM-Educação) são dois dos principais indicadores utilizados para este propósito. Este estudo tem como objetivo propor um novo índice capaz de explicar o desenvolvimento humano em educação para os municípios brasileiros, por meio da técnica de análise fatorial e incluindo importantes dimensões educacionais, as quais não são consideradas nos índices supracitados. Os resultados permitiram realizar análises mais acuradas das especificidades da rede de ensino dos municípios. O desenvolvimento humano em educação dos municípios do Brasil, medido pelo índice aqui proposto, apresenta resultados estatisticamente menores em comparação ao IDHM e IFDM e, portanto, conclui-se que esses dois indicadores podem não estar refletindo toda a realidade e complexidade do sistema educacional brasileiro ao desconsiderar importantes indicadores.

Academic women departmental heads’ coping mechanisms during COVID-19: A capabilities approach perspective
Authors: Ramohai Nthuna Juliet , Holtzhausen Somarie
Published: January 2023

This paper explored women departmental heads’ leadership experiences in higher education during the COVID-19 pandemic. This paper highlighted aspects of their care and coping mechanisms in terms of them working in virtual spaces. Most scholars have examined employees’ effects and challenges while working from home during a lockdown. However, most studies are silent on women in leadership, especially concerning the provision of resources to enhance effective leadership during this crisis. The paper draws on three concepts of Sen’s Capabilities approach: functionings, freedoms, and agency. This approach facilitates an incisive understanding of institutional and individual coping mechanisms that might be beneficial for women leaders to mitigate the challenges of the devastating COVID-19 lockdowns. The qualitative narrative approach, supported by a feminist lens, provides a critical, in-depth understanding of the real-life stories of women in leadership positions when making-sense of their challenges in working in a virtual environment. Data which was collected through semi-structured interviews with ten female heads of department, was analysed thematically by applying the Capabilities Approach as an analytical tool. The findings indicated that functionings and freedoms are inextricably intertwined to institutional ethnographies. These ethnographies might support or hamper the coping capabilities of women leaders in academic institutions, especially during the COVID-19 crisis.

Published: January 2023

This paper presents the assessment of masonry wall defects in residential buildings in Lithuania. The created model is based on a multi-attribute evaluation of wall defects in residential buildings in Lithuania, the determination of their optimality criterion values calculated according to Laplace’o rule. The developed defect assessment algorithm has advantages to be used by repair contractors and people or companies performing building maintenance. First, the model allows planning the course of repair works properly. When carrying out repair work in a building with recurring defects that mainly occur at the building site, proper workflow and its planning are essential. The proposed model could be applied further to a building owner to select the most damaged walls. A background and a description of the proposed model are provided, and several key findings from the data analyses are presented.

In 2021 May, the Dark Energy Spectroscopic Instrument (DESI) began a 5 yr survey of approximately 50 million total extragalactic and Galactic targets. The primary DESI dark-time targets are emission line galaxies, luminous red galaxies, and quasars. In bright time, DESI will focus on two surveys known as the Bright Galaxy Survey and the Milky Way Survey. DESI also observes a selection of “secondary” targets for bespoke science goals. This paper gives an overview of the publicly available pipeline (desitarget) used to process targets for DESI observations. Highlights include details of the different DESI survey targeting phases, the targeting ID (TARGETID) used to define unique targets, the bitmasks used to indicate a particular type of target, the data model and structure of DESI targeting files, and examples of how to access and use the desitarget code base. This paper will also describe “supporting” DESI target classes, such as standard stars, sky locations, and random catalogs that mimic the angular selection function of DESI targets. The DESI target-selection pipeline is complex and sizable; this paper attempts to summarize the most salient information required to understand and work with DESI targeting data.
A Low-mass, Pre-main-sequence Eclipsing Binary in the 40 Myr Columba Association—Fundamental Stellar Parameters and Modeling the Effect of Star Spots

Young eclipsing binaries (EBs) are powerful probes of early stellar evolution. Current models are unable to simultaneously reproduce the measured and derived properties that are accessible for EB systems (e.g., mass, radius, temperature, and luminosity). In this study we add a benchmark EB to the pre-main-sequence population with our characterization of TOI 450 (TIC 77951245). Using Gaia astrometry to identify its comoving, coeval companions, we confirm TOI 450 is a member of the ∼40 Myr Columba association. This eccentric (e = 0.2969), equal-mass (q = 1.000) system provides only one grazing eclipse. Despite this, our analysis achieves the precision of a double-eclipsing system by leveraging information in our high-resolution spectra to place priors on the surface-brightness and radius ratios. We also introduce a framework to include the effect of star spots on the observed eclipse depths. Multicolor eclipse light curves play a critical role in breaking degeneracies between the effects of star spots and limb-darkening. Including star spots reduces the derived radii by ∼2% from a unspotted model (>2σ) and inflates the formal uncertainty in accordance with our lack of knowledge regarding the starspot orientation. We derive masses of 0.1768( ± 0.0004) and 0.1767( ± 0.0003) M
⊙, and radii of 0.345(±0.006) and 0.346(±0.006) R
⊙ for the primary and secondary, respectively. We compare these measurements to multiple stellar evolution isochones, finding good agreement with the association age. The MESA MIST and SPOTS (f
s = 0.17) isochrones perform the best across our comparisons, but detailed agreement depends heavily on the quantities being compared.
Position and Proper Motion of Sagittarius A* in the ICRF3 Frame from VLBI Absolute Astrometry
Authors: Gordon David , de Witt Aletha , Jacobs Christopher S.
Published: January 2023

Sagittarius A* (Sgr A*) is a strong, compact radio source believed to be powered by a supermassive black hole at the galactic center. Extinction by dust and gas in the galactic plane prevents observing it optically, but its position and proper motion have previously been estimated using radio interferometry. We present new VLBI absolute astrometry measurements of its precise position and proper motion in the frame of the third realization of the International Celestial Reference Frame (ICRF3). The observations used were made at 52 epochs on the VLBA at K band (24 GHz) between 2006 June and 2022 August. We find the proper motion of Sgr A* to be −3.128 ± 0.042 mas yr−1 in R.A. and −5.584 ± 0.075 mas yr−1 in decl., or 6.400 ± 0.073 mas yr−1 at a position angle of 209.°26 ± 0.°51. We also find its J2000 ICRF3 coordinates at the 2015.0 proper motion epoch to be 17h45m40.ˢ034047 ± 0.ˢ000018, −29°00′28.″21601 ± 0.″00044. In galactic coordinates, Sgr A* shows proper motion of −6.396 ± 0.071 mas yr−1 in galactic longitude and −0.239 ± 0.045 mas yr−1 in galactic latitude, indicating solar motion of 248.0 ± 2.8 km s−1 in the galactic plane and 9.3 ± 1.9 km s−1 toward the north galactic pole.
Fast Outflowing Warm Absorbers in Narrow-line Seyfert 1 Galaxy PG 1001+054 Revealed by HST/COS Spectra
Authors: Fu Xiao-Dan , Wang Junfeng , Xu 许 Xiaoyu 啸宇 , Zhang Zhi-Xiang
Published: January 2023

Narrow-line Seyfert 1 (NLS1) galaxies are an important type of active galactic nucleus (AGN), generally expected to be accreting at a high Eddington rate. The properties of their outflows and importance of AGN feedback remain intriguing. We report on the discovery of fast outflowing warm absorbers (WAs) in the NLS1 PG 1001+054 with velocities in the range of ∼7000–9000 km s−1. They are identified with blueshifted Lyα, N v, and Si iv lines in the high-resolution ultraviolet (UV) spectra taken with the Cosmic Origins Spectrograph on board the Hubble Space Telescope. We perform photoionization modeling using XSTAR with three WAs. The derived physical properties are typical of WAs in terms of ionization and column density, whereas the outflow velocities are significantly higher. The estimated location of these WAs ranges from 1 to 73 parsecs away from the AGN. Together with previous detection of high ionization absorbers in the X-ray for PG 1001+054, we suggest that fast outflowing UV absorbers are probably part of a multiphase outflow. Such a structure is likely produced by the outflow launched from the AGN at an accretion disk scale, which shocks the ambient interstellar medium (ISM), producing stratified absorbers. Assuming contribution from the three WAs at tens of parsecs, the estimated ratio between the kinetic power of the outflow and AGN Eddington luminosity could reach 1.7%, raising the possibility of sufficient influence on the host galaxy when compared to some theoretical models for efficient AGN feedback.

Published: January 2023

Sunspot light bridges (LBs) exhibit a wide range of short-lived phenomena in the chromosphere and transition region. In contrast, we use here data from the Multi-Application Solar Telescope (MAST), the Interface Region Imaging Spectrograph (IRIS), Hinode, the Atmospheric Imaging Assembly (AIA), and the Helioseismic and Magnetic Imager (HMI) to analyze the sustained heating over days in an LB in a regular sunspot. Chromospheric temperatures were retrieved from the MAST Ca ii and IRIS Mg ii lines by nonlocal thermodynamic equilibrium inversions. Line widths, Doppler shifts, and intensities were derived from the IRIS lines using Gaussian fits. Coronal temperatures were estimated through the differential emission measure, while the coronal magnetic field was obtained from an extrapolation of the HMI vector field. At the photosphere, the LB exhibits a granular morphology with field strengths of about 400 G and no significant electric currents. The sunspot does not fragment, and the LB remains stable for several days. The chromospheric temperature, IRIS line intensities and widths, and AIA 171 and 211 Å intensities are all enhanced in the LB with temperatures from 8000 K to 2.5 MK. Photospheric plasma motions remain small, while the chromosphere and transition region indicate predominantly redshifts of 5–20 km s−1 with occasional supersonic downflows exceeding 100 km s−1. The excess thermal energy over the LB is about 3.2 × 1026 erg and matches the radiative losses. It could be supplied by magnetic flux loss of the sunspot (7.5 × 1027 erg), kinetic energy from the increase in the LB width (4 × 1028 erg), or freefall of mass along the coronal loops (6.3 × 1026 erg).

We present observations of the rapid decay of a penumbral sector associated with a strong light bridge (LB) in the active region NOAA 12680 by analyzing the scattered light-corrected Solar Dynamics Observatory/Helioseismic and Magnetic Imager data. At the beginning of penumbral decay, some dark structures gradually broke away from the umbra to which they were attached. The intensity, vertical field strength, and magnetic inclination of the dark structures are intermediate between those of the umbra and penumbra. And a strong LB formed in the umbra, which originated from the intrusion of neighboring penumbral filaments. With the formation of an LB, the total magnetic flux in the whole penumbra decreased, and a penumbral sector of the sunspot rapidly disappeared on one side of the LB. After performing a partition analysis of the penumbra, it was found that the decay rate in this region of the penumbral sector is significantly accelerated after the appearance of an outward motion of magnetic flux along the LB. The area of this penumbral sector decreased from 21–16 MSH in 4 hr. The reduction in area in this penumbral sector is accompanied by a large decay rate of the magnetic flux, 2.5 × 1019 Mx hr−1. These results suggest that the rapid decay of the penumbral sector is associated with the LB. The appearance of dark structures in the penumbra and the strong LB in the umbra may offer a hint that the origin of massive flux migration from the sunspot umbra may have accelerated the decay of the sunspot.

Massive young stellar objects (MYSOs) play a crucial role in star formation. Given that MYSOs were previously identified based on the extended structure and the observational data for them is limited, screening the Wide-field Infrared Survey Explorer (WISE) objects showing green features (for the common coding of the 4.6 μm band as the green channel in three-color composite WISE images) will yield more MYSO candidates. Using WISE images in the whole Galactic plane (0° < l < 360° and ∣b∣ < 2°), we identified sources with strong emissions at the 4.6 μm band, then according to morphological features divided them into three groups. We present a catalog of 2135 WISE Green Objects (WGOs). 264 WGOs have an extended structure. 1366 WGOs show compact green features but without extended structure. 505 WGOs have neither extended structure nor green features, but the intensity at 4.6 μm is numerically at least 4.5 times that of 3.4 μm. According to the analysis of the coordinates of WGOs, we find WGOs are mainly distributed in ∣l∣ < 60°, coincident with the position of the giant molecular clouds in ∣l∣ > 60°. Matching results with various masers show that those three groups of WGOs are at different evolutionary stages. After crossmatching WGOs with published YSO survey catalogs, we infer that ∼50% of WGOs are samples of newly discovered YSOs. In addition, 1260 WGOs are associated with Hi-GAL sources, according to physical parameters estimated by spectral energy distribution fitting, of which 231 are classified as robust MYSOs and 172 as candidate MYSOs.

BACKGROUND: Down syndrome is a chromosome 21 disorder and the most common cause of physical abnormalities including midface hypoplasia, facial hypotonia, and also drooling. Drooling is unintentional anterior salivary flow from the mouth. The objectives of the study is to determine and analyze the effects of midfacial hypoplasia and facial hypotonia on drooling in Down syndrome children. Subject and method:
METHODS: of the research is analytic correlational. Sample retrievement using purposive sampling technique and obtained 20 samples that fulfills the inclusive criterias, consisting of 13 boys and 7 girls with an age range of 6 to 16 years old.
RESULTS AND DISCUSSION: The results were tested statistically by Kendall Coefficient of Concordance Test and Spearman Coefficient of Rank Correlation Test. The results showed that the effect of midfacial hypoplasia, facial hypotonia at rest, and during clenching on drooling is very significant (p-value 0.0002) with Kendall Coefficient of Concordance. Spearman Coefficient of Rank Correlation test results show correlation of midface hypoplasia on drooling is not significant (p-value 0,1265). Facial hypotonia at rest has a very significant correlation on drooling (p-value 0,0000) and during clenching also has a very significant correlation (p-value 0,0000).
CONCLUSION: Conclusion of the research is there are effects of midface hypoplasia, facial hypotonia at rest and facial hypotonia during clenching on drooling, also facial hypotonia at rest and facial hypotonia during clenching on drooling, but no effect of midface hypoplasia on drooling in Down syndrome children.
Fat Embolism Syndrome Without Bone Fracture: Is It Possible?
Authors: Bajraktari Mustafa , Naco Majlinda , Huti Gentian , Arapi Blerim , Domi Rudin
Published: January 2023

BACKGROUND: Fat embolism syndrome is a life challenge syndrome. Early diagnosing and treatment can significantly improve the patient’s prognosis and likelihood of success. This syndrome occurs mainly after long bones fractures or orthopedic surgery up to 95% of diagnosed cases, but in unusual situation can be faced as well. These rare situations include diabetes mellitus, video-assisted thoracoscopies, fatty liver, and fat injection in plastic and cosmetic procedures. The likelihood of this syndrome can be increased if multiplex long bones fractures occur in the same patient simultaneously. This syndrome is usually manifested with respiratory changes (hypoxemia and ARDS), neurological focal symptoms (confusion, headache, aphasia, and hemiplegia), and skin abnormalities (petechias, and rush in conjunctiva and oral mucosa). The clinical scenario begins typically after 24−72 h of injury, and mainly, respiratory changes are the first, followed by neurological abnormalities and finally petechias as the most significant sign.

CASE REPORT: In this case, we report a rare case of unexpected fat embolism syndrome after soft-tissue minimal trauma. This is the first case that we faced according to literature, and the aim of reporting this case is to emphasize that fat syndrome embolism can happen perhaps in every trauma patient even in minor soft-tissue trauma in absence of bone fractures.

CONCLUSION: We strongly suggest that this case should make the physicians taking in consideration fat embolism syndrome even if bone fracture missed, to early diagnosing and adequately treating the patient, and optimizing his chances to survive.
Le rôle des maréchaux de la Grande Guerre dans la promotion des commandeurs du désastre de juin 1940
Authors: Schiavon Max
Published: January 2023

Les maréchaux de la Première Guerre mondiale, incarnations de la victoire et objets d’une extraordinaire glorification dans l’entre-deux-guerres, ont soutenu ou poussé vers la haute hiérarchie militaire des « poulains » qui assumeront de hautes responsabilités au cours de la Seconde Guerre mondiale. Qu’en était-il de ce lien ? Cette filiation a-t-elle joué un rôle dans la défaite de 1940 ?

Notes sur Diderot et les simulacres errants
Authors: Sarrasin Robichaud Philippe
Published: January 2023

À la fois nécessaire à la pensée humaine et potentiellement illusoire, le simulacre est une entité trouble chez Diderot. Si, comme le « mot », il s’oppose à la « chose », il n’en fait pas moins partie du monde matériel. Proche des écrits d’Épicure et de son disciple Lucrèce, la conception de l’encyclopédiste en fait une sorte de bruissement du réel. Il s’agit d’une voix à écouter, mais avec laquelle il est nécessaire de dialoguer de manière curieuse et critique afin de ne pas en faire une sentence univoque qui mènerait infailliblement à l’idolâtrie.
Suzanne simulacre
Authors: Igalens Jean-Christophe
Published: January 2023

Cet article s’intéresse aux simulacres à apparence humaine évoqués dans La Religieuse de Diderot pour montrer les relations qui les unissent et interpréter ainsi la signification de ces images : des enjeux essentiels de l’œuvre s’y condensent, le roman militant et pathétique s’y articule avec les paradoxes qui déjouent et complexifient, sans cependant les abolir, ses oppositions structurantes (liberté/aliénation ; innocente passive/persécutrices actives ; naïveté/séduction, etc.). L’image d’une Suzanne-automate est associée à la représentation de l’aliénation, depuis les vœux que le personnage prononce en étant « physiquement aliénée » jusqu’à la répétition machinale des gestes du couvent après son évasion. Le terme de « simulacre » apparaît à propos des images peintes et en particulier des portraits, associé à une opposition cruciale entre les images qui laissent froid et celles qui affectent. L’écriture romanesque de Diderot impose alors de s’interroger non seulement sur la séduction ambivalente d’une Suzanne-tableau, mais bien sur le pouvoir d’une Suzanne-simulatrice, d’une Suzanne-pantomime. Les comparaisons avec une statue concentrent enfin les relations problématiques du personnage et de la narratrice avec le désir. Si la réduction de Suzanne à un simulacre dit la dépossession de soi à laquelle le personnage semble condamné, le réinvestissement du simulacre par Suzanne-tableau et Suzanne-pantomime constitue aussi la manifestation romanesque d’une résistance à cette dépossession.
L’évaluation des élèves chez les Philanthropistes. Entre rupture et tradition renouvelée
Authors: Craïs Alexa
Published: January 2023

L’école expérimentale allemande du xviii e , le Philanthropinum , est restée célèbre à cause ou grâce à son « tableau des mérites ». Cet article revient sur l’origine, l’usage et la pertinence d’un tel outil d’évaluation. Il a été associé à un registre des mérites dans lequel les enseignants notaient leurs appréciations. Y a-t-il convergence entre les deux outils ? Quels étaient les critères retenus ? Etaient-ils en accord avec le projet d’établissement et plus largement avec les objectifs que les philanthropistes avaient assignés à l’éducation ? Comment s’inséraient-ils dans les dispositifs de régulation mis en place au sein de l’établissement ?
Le débat sur l’héritage des Lumières dans l’éducation à la citoyenneté mondiale
Authors: Coignard Tristan
Published: January 2023

Dans cet article, on se propose, dans un premier temps, de soumettre à examen différents points de la critique formulée à l’égard de l’éducation cosmopolitique. Par la suite, il s’agit de montrer les potentialités d’un tel projet éducatif, à partir du moment où l’on se réfère à l’héritage des Lumières et où l’on intègre celui-ci à une démarche actualisée. On se demandera en particulier si les Lumières permettent d’opérer un déplacement vers des enjeux spécifiquement politiques de la citoyenneté mondiale.
L’identité humaine entre nature et histoire : repenser l’égalité à partir de la critique par Massimo Fagioli de la raison des Lumières
Authors: Profeti Livia
Published: January 2023

L’essai traite de la critique antihumaniste de Lumières, qui s’appuie sur la contestation de l’existence de la « nature humaine » et met donc en question l’égalité universelle, fondamentale pour l’esprit des Lumières. Dans la première partie du texte, l’auteure relève que la contestation actuelle est liée étroitement à la négation parallèle du sujet moderne. Une double négation, de la « nature » et de la subjectivité humaines, qui rejoint aujourd’hui, paradoxalement, autant les mouvements communautaires ethniques de droite qu’une grande partie de la pensée philosophique postmoderne, dite de gauche. La seconde partie de l’essai est consacrée à la critique constructive du concept d’égalité des Lumières par le psychiatre italien Massimo Fagioli et basée sur sa propre « théorie de la naissance humaine ». Dans ses conclusions, l’auteure indique comme cette théorie psychiatrique est en mesure d’apporter des arguments utiles à la quête philosophique d’une nouvelle idée d’égalité pour notre temps.
Le jeune Reinhart Koselleck et les Lumières
Authors: Quelennec Bruno
Published: January 2023

L’article propose une relecture de Kritik und Krise (1959) et tente d’identifier le cadrage normatif de cet ouvrage. Il s’intéresse à la constellation intellectuelle au sein de laquelle le jeune Koselleck écrit Kritik und Krise . Il s’agit de savoir s’il est un Aufklärer ou un Gegenaufklärer dans le contexte politique allemand des années 1950. Ceci implique de comprendre le couple conceptuel antonyme Lumières/contre-Lumières tel qu’il est mobilisé dans les débats intellectuels allemands de l’après-guerre, où la question du rapport aux Lumières est intimement liée à celui au libéralisme, au passé nazi et à la guerre froide. L’auteur montre que, contrairement à ce que l’historien allemand indique dans ses textes et interviews autobiographiques des années 1990 et 2000, il n’est certainement pas, dans les années 1950, un représentant du Cold War Liberalism .
L’universalisme, un élément rhétorique dans la controverse postcoloniale
Authors: Collier Anne-Claire
Published: January 2023

À travers l’étude d’un corpus de textes et de trajectoires sociales, et en prenant comme prisme le lien entre universalisme et postcolonialisme, cet article propose une typologie qui regroupe en trois classes les parties prenantes de la controverse autour de la réception des études postcoloniales en France. Il s’agit de comprendre comment la controverse se déploie dans et hors des frontières de l’espace savant ainsi que de saisir les multiples perceptions du « modèle républicain français ».
