Introdução: Estudo bibliográfico que aborda os impactos das redes sociais, com ênfase no Instagram, no desenvolvimento e desconstrução da personalidade dos usuários de forma que a saúde mental dos indivíduos cede a uma realidade fora de seu contexto cultural, estrutural e social. Redes sociais produzem ao indivíduo uma ideia de socialização com o outro prejudicial, trazendo danos para a sua construção ou dificuldades de personificação do indivíduo na elaboração sobre si mesmo. Assim mostra-se importância para a identificação dessas redes como um potencial maior na contribuição dos indivíduos. Conclusão: Em suma, cogita-se que o Instagram ou as redes sociais correspondem com uma grande influência na estrutura do indivíduo, pois considera-se que é um alicerce na comunicação e identificação de fenômenos sociais.
Introduction: This bibliographic study on how social networks, with an emphasis on Instagram, can deconstruct users' personalities in such a way that individuals' mental health gives way to a reality outside their cultural context, structural and social. Social networks produce to the individual an idea of ??socialization with others that is harmful, bringing damage to its construction or difficulties in personifying the individual in elaborating on himself. Thus, it is important to identify these networks as having greater potential in the contribution of individuals. Conclusion: In short, it is considered that Instagram or social networks have a great influence on the structure of the individual, as it is considered to be a foundation in the communication and identification of social phenomena.

Background: Centella asiatica (CA) or pegagan or horse foot leaves is one of the traditional plants widely used to treat various diseases. This study aims to evaluated the content of total phenolics and total flavonoids, as well as the antioxidant activity of Centella asiatica extracts from different methods and solvents.
Methods: The sample was divided into three groups, (70% ethanol maceration, methanol maceration and water infundation). Total phenolic compounds in the extract were determined by the Follin-Ciocalteu method, total flavonoid content was determined by the aluminum chloride colorimetric assay method, and antioxidant activity was assessed by the immersion DPPH free radicals method. Determination data of IC50 was assessed by regression test and differences between the three extract groups were tested by ANOVA or Kruskal Wallis test.
Results: The highest total phenolics and total flavonoid were obtained in Centella asiatica extract with water solvent, 251.88 ± 0.96 mg/g GAE and 7.26 ± 0.03 mg/g QE, followed by 70% ethanol and methanol. In addition, the best antioxidant activity was also shown in the extract with water, namely 24.09 ± 0.01. The difference test results between all groups showed significant results (p<0.05) in all parameters.
Conclusion: The best content of total phenolic, total flavonoid, and antioxidant activity was obtained by infundation with water solvent. In the maceration method, the best content of the three parameters measured was obtained in the group with ethanol solvent.

Authors: Padilla Sánchez Ariana Julissa , Padilla Sánchez Jesús Francisco 
Published: November 2023

Introducción. El síndrome de Reye (SR) es un trastorno poco común en la práctica médica actual. Ocasiona una encefalopatía aguda no inflamatoria asociada a una insuficiencia hepática por infiltración grasa, con una diversa variabilidad clínica, que de no ser reconocida oportunamente conlleva a un elevado riesgo de morbimortalidad. Objetivo. Proporcionar un análisis integral y sistemático de las características demográficas, cuadro clínico, hallazgos diagnósticos, manejo inicial y factores pronósticos del SR. Material y métodos. Se realizó una revisión sistemática de estudios encontrados en las bases de datos PubMed, Google académico y SciELO. Resultados. Se incluyeron 18 artículos. Las dos enfermedades virales más citadas fueron la influenza y la varicela. Los salicilatos cumplen un papel como cofactor. Las secuencia típica fue un pródromo viral que antecede a la emesis y deterioro neurológico. Los hallazgos séricos más frecuentes fueron hiperamonemia, transaminasemia y prolongación de la protrombina. La identificación precoz permite un tratamiento temprano y mejora el pronóstico. Conclusiones. Existe un atraso importante en las últimas décadas respecto al aporte de evidencia científica sobre el SR, atribuible quizá a los escasos casos en la actualidad. La comprensión del abordaje diagnóstico y terapéutico disminuye la mortalidad y mejora el pronóstico del infante al aminorar el riesgo de secuelas neurológicas crónicas.
Kepler Bonus: Light Curves of Kepler Background Sources
Authors: Martínez-Palomera Jorge , Hedges Christina , Dotson Jessie 
Published: November 2023

Abstract
NASA’s Kepler primary mission observed about 116 deg2 in the sky for 3.5 consecutive years to discover Earth-like exoplanets. This mission recorded pixel cutouts, known as target pixel files (TPFs), of over 200,000 targets that were selected to maximize the scientific yield. The Kepler pipeline performed aperture photometry for these primary targets to create light curves. However, hundreds of thousands of background sources were recorded in the TPFs and have never been systematically analyzed. This work uses the linearized field deblending (LFD) method, a point-spread function (PSF) photometry algorithm, to extract light curves. We use Gaia Data Release 3 as the input catalog to extract 606,900 light curves from long-cadence TPFs; 406,548 are new light curves of background sources, while the rest are Kepler’s targets. These light curves have comparable quality to those computed by the Kepler pipeline, with combined differential photometric precision values <100 ppm for sources G < 16. The light-curve files are available as high-level science products at the Mikulski Archive for Space Telescopes. Files include PSF and aperture photometry as well as extraction metrics. Additionally, we improve the background and PSF modeling in the LFD method. The LFD method is implemented in the Python library psfmachine. We demonstrate the advantages of this new data set with two examples: deblending of contaminated false-positive Kepler objects of interest identifying the origin of the transit signal and the changes in estimated transit depth of planets using PSF photometry, which improves dilution when compared with aperture photometry. This new nearly unbiased catalog enables further studies in planet search, occurrence rates, and other time-domain studies.

Published: November 2023

Abstract
We extract the galaxy density and momentum power spectra from a subset of early-type galaxies in the Sloan Digital Sky Survey (SDSS) DR7 main galaxy catalog. Using galaxy distance information inferred from the improved fundamental plane described in Yoon and Park, we reconstruct the peculiar velocities of the galaxies and generate number density and density-weighted velocity fields, from which we extract the galaxy density and momentum power spectra. We compare the measured values to the theoretical expectation of the same statistics, assuming an input Λ cold dark matter (CDM) model and using a third-order perturbative expansion. After validating our analysis pipeline with a series of mock data sets, we apply our methodology to the SDSS data and arrive at constraints

Spatially Resolved Temperature and Density Structures of Nearby H ii Regions
Authors: Jin 金 Yifei 刈非 , Sutherland Ralph , Kewley Lisa J. , Nicholls David C. 
Published: November 2023

Abstract
Photoionization models frequently assume constant temperature or density within H ii regions. We investigate this assumption by measuring the detailed temperature and density structures of four H ii regions in the Large Magellanic Cloud and the Small Magellanic Cloud, using integral-field spectroscopic data from the Wide-Field Spectrograph on the ANU 2.3 m telescope. We analyze the distribution of emission lines of low-ionization, intermediate-ionization, and high-ionization species. We present the complex electron temperature and density structures within H ii regions. All four nebulae present a negative gradient in the electron density profile. Both positive and negative temperature gradients are observed in the nebulae. We create a series of nebula models with constant interstellar medium (ISM) pressure and varying temperature and density distributions. A comparison of the line ratios between our H ii regions and models suggests that none of the simple nebula models can reproduce the observed temperature and density structures. Comparison between the models and the data suggests that the ISM pressure of nebulae in the LMC and SMC is between log(P/k) = 6 and 7.5. Complex internal structures of the nebulae highlight the importance of future Monte Carlo photoionization codes for accurate nebula modeling, which include a comprehensive consideration of arbitrary geometries of H ii regions.
Radial Transport in the Earth’s Radiation Belts: Linear, Quasi-linear, and Higher-order Processes

Published: November 2023

Abstract
Observational studies of the Earth’s radiation belts indicate that Alfvénic fluctuations in the frequency range of 2–25 mHz accelerate electrons to relativistic energies. For decades, statistical models of radiation belts have quantified the impact of Alfvénic waves in terms of quasi-linear diffusion. However, quasi-linear models are inadequate to quantify Alfvénic radial transport occurring on timescales comparable to the azimuthal drift period of 0.1–10 MeV electrons. With recent advances in observational methodologies offering coverage of the Earth’s radiation belts on fast timescales, a theoretical framework that distinguishes between fast and diffusive radial transport can be tested for the first time in situ. In this report, we present a drift-kinetic description of radial transport for planetary radiation belts. We characterize fast linear processes and determine the conditions under which higher-order effects become dynamically significant. In the linear regime, wave–particle interactions are categorized in terms of resonant and nonresonant responses. We demonstrate that the phenomenon of zebra stripes is nonresonant and can originate from injection events in the inner radiation belts. We derive a radial diffusion coefficient for a field model that satisfies Faraday’s law and that contains two terms: one scaling as L
10 independent of the azimuthal number m, and a second scaling as m

L
6. In the higher-order regime, azimuthally symmetric waves with properties consistent with in situ measurements can energize 10–100 keV electrons in less than a drift period. This process provides new evidence that acceleration by Alfvénic waves in radiation belts cannot be fully contained within diffusive models.
KAPPA: A Package for the Synthesis of Optically Thin Spectra for the Non-Maxwellian κ-Distributions. III. Improvements to Ionization Equilibrium and Extension to κ < 2
Authors: Dzifčáková Elena , Dudík Jaroslav , Pavelková Martina , Solarová Božena , Zemanová Alena 
Published: November 2023

Abstract
The KAPPA package is designed for calculations of optically thin spectra for the non-Maxwellian κ-distributions. This paper presents an extension of the database to allow calculations of the spectra for extreme values of κ < 2, which are important for accurate diagnostics of the κ-distributions in the outer solar atmosphere. In addition, two improvements were made to the ionization equilibrium calculations within the database. First, the ionization equilibrium calculations now include the effects of electron impact multi-ionization (EIMI). Although relatively unimportant for Maxwellian distribution, EIMI becomes important for some elements, such as Fe and low values of κ, where it modifies the ionization equilibrium significantly. Second, the KAPPA database now includes the suppression of dielectronic recombination at high electron densities, evaluated via the suppression factors. We find that at the same temperature, the suppression of dielectronic recombination is almost independent of κ. The ionization equilibrium calculations for the κ-distributions are now provided for a range of electron densities.
Contribution des acteurs de terrain pour une appréhension actualisée des enjeux de l’accès aux soins par la télésanté
Authors: Grandclaude Sabrina , Nobre Thierry , Grandclaude Didier 
Published: November 2023

Dans un contexte de désertification médicale, cette recherche analyse les perspectives d’amélioration de l’accès aux soins par la télésanté. Partant du constat que l’amélioration de l’accès aux soins par la télésanté est toujours analysée selon le même prisme que la médecine pratiquée en présentiel, cette recherche pose la question suivante : quelles peuvent être les perspectives d’amélioration de l’accès aux soins par la télésanté ? Elle vise à proposer une compréhension actualisée, à l’ère du numérique, du concept d’accès aux soins. Pour parvenir à cet objectif, la recherche mobilise, au niveau théorique, une grille d’analyse élargie de l’accès aux soins, développée par Saurman (2016). Au niveau empirique, la recherche propose l’étude de 96 projets d’innovation en santé, ces innovations étant, pour la plupart, soit portées par un cœur de projet numérique de télésanté, soit soutenues par les Technologies de l’Information et de la Communication (TIC). Une approche complémentaire de données primaires, 52 entretiens avec les chefs de projet, et secondaires, les documents relatifs à la description du contenu de ces projets, est proposée. Les résultats soulignent le besoin de changer notre regard, à l’ère du numérique, sur le concept d’accès aux soins. Le rôle majeur de dimensions telles que l’acceptabilité technologique et la sensibilisation pour améliorer l’accès aux soins par la télésanté est identifié dans les discours des acteurs, ce qui montre l’importance d’appréhender l’accès aux soins par une approche managériale propre aux sciences de gestion.
Du cinéma dans, en dehors ou en marge de la classe ? L’introduction du septième art à l’école (1963-1999)
Authors: Souillés-Débats Léo 
Published: November 2023

Reconnu progressivement comme un art durant l’entre-deux-guerres en France, le cinéma devient, à partir de la seconde moitié du XXe siècle, un enjeu majeur dans le domaine de l’enseignement. Mais si l’État reconnaît la nécessité d’accorder une place officielle au septième art au sein de l’école, aucune mesure concrète et véritablement ambitieuse n’aboutira, à l’échelle nationale, avant les années 1980. Pendant près de trente ans, l’enseignement du cinéma trouve donc une place ambivalente, partagé entre temps scolaire et périscolaire, en marge ou au sein même de la classe, au gré des initiatives ponctuelles et individuelles portées par des enseignants cinéphiles généralement investis dans les réseaux de l’éducation populaire et encouragés par quelques inspecteurs et chefs d’établissements précurseurs, avant d’obtenir un statut clairement délimité au sein de l’espace éducatif à la fin du siècle. Le présent article se propose ainsi d’étudier cette période charnière qui voit le cinéma traverser cette frontière du périscolaire pour trouver sa place dans la salle de classe en interrogeant les enjeux pédagogiques, politiques et économiques que cette reconnaissance institutionnelle suppose.
Notre École, institution d’enseignement à distance pour une élite conservatrice, 1907-1926
Authors: Kergariou (de) Étienne 
Published: November 2023

Notre École est une institution de cours par correspondance pour les élèves de premier et deuxième cycles de l’enseignement secondaire, réservé à l’époque à l’élite sociale. Elle est certainement l’une des plus anciennes expériences d’éducation à distance pour des enfants. Fondée par des parents d’élèves conservateurs, en réaction à la fermeture des écoles congréganistes de France au début du XXe siècle, elle développe une pédagogie en exploitant les technologies disponibles à l’époque. L’ensemble des numéros de la revue hebdomadaire, médium de ces cours, est conservé à la Bibliothèque nationale de France et permet de découvrir cette institution pédagogiquement innovante et politiquement conservatrice.
Selenium-based black bronze treatment, as compared to other patination technologies of ancient and historic black bronzes

Published: November 2023

Metalworkers have used black patinas on high-status diminutive bronzes in the Mediterranean and Far East beginning in Antiquity. The textual evidence for these bronzes can be ambiguous, but their compositions have been intensively studied and characterized in recent decades. In addition to the ancient technologies, elemental and molecular analysis of black bronzes across millennia and cultures reveals the frequent presence of selenium-based patinas, which we have identified as copper selenite dihydrate. Selenium patination formulations have long been viewed as the 19th century response to the black patinated alloys (such as shakudō and shibuichi) that arrived in Europe from Japan beginning in the Meiji restoration. However, the 19th century European technological literature does not support this, and so selenium-based patination technologies have remained obscure. In this paper, we examine the proliferation of selenium-based technologies in the early 20th century, along with the merits of hypotheses for their origins in patina formulations.
Les tableaux cultuels d’Égypte romaine : étude matérielle des deux panneaux du musée du Louvre (Dioscure, MND 193 – E 10815 ; Hèrôn et Lycurgue, RFML.AE.2020.8.1)
Authors: Thomas Caroline , Brunel-Duverger Lucile 
Published: November 2023

L’acquisition récente par le département des Antiquités égyptiennes du musée du Louvre d’un rare panneau peint représentant les dieux Hèrôn et Lycurgue a coïncidé avec un programme d’étude matérielle mené sur la collection de portraits de momie et de tableaux cultuels (Fayoum). Cette recherche s’inscrit dans le cadre du projet international Appear sur les panneaux peints d’Égypte romaine, dont l’objectif est la mise en commun des résultats afin de mieux appréhender les processus de création de ces objets. Cet article présente les données issues de la campagne menée sur les deux tableaux cultuels conservés au Louvre, en les mettant en perspective avec celles obtenues sur d’autres panneaux cultuels et sur la production contemporaine des portraits de momie. Il en ressort que les tableaux de divinités semblent partager des caractéristiques techniques communes : réalisés avec des bois indigènes, ils sont peints à la détrempe selon une palette typique de la polychromie de l’Égypte romaine.

Published: November 2023

Objective:
Aluminum phosphide (ALP) and zinc phosphide (ZnP) are toxic agrochemical pesticides, which are commonly used as an agent of self-harm in developing countries. Because of high toxicity of phosphides, we evaluated toxico-epidemiology ALP and ZnP poisoning in with respect to outcome.

Methods:
We performed a cross-sectional study with retrospective chart review including the records for patients admitted due to phosphide poisoning (ALP, ZnP) in a poisoning referral center in Khorshid Hospital, affiliated with Isfahan University of Medial Sciences, Isfahan, Iran. Demographic characteristics, clinical manifestations, outcome (survived or death), and length of hospital stay for the patients were recorded in a data collecting form. Binary backward stepwise logistic regression was used for outcome prediction.

Findings:
Sixty patients were evaluated in the study. The mean age of patients was 27.61. Thirty-nine patients were men. 96.7% of the patients ingested it intentionally. Most of the patients on admission were conscious (66.7%). Abnormality of EKG was noted in 8.3%. The mortality in ALP and ZnP poisoning was 39.2% and 22.2%, respectively. Serum bicarbonate and base excess in the venous blood gas analysis, systolic blood pressure, and serum sodium level were significantly different between patients with ALP and ZnP poisoning on admission time (P < 0.05). On admission, systolic blood pressure was an important predictive factor for mortality (odds ratio 4.87; 95% confidence interval: 1.5–15.45; P = 0.007).

Conclusion:
The rate of mortality in phosphide poisoning is high. Knowing predictive factors for mortality help physicians for selecting patients in intensive care unit admission and aggressive treatment.
