Metal Abundances of Intermediate-redshift Active Galactic Nuclei: Evidence for a Population of Lower-metallicity Seyfert 2 Galaxies at z = 0.3–0.4
Authors: Carr David J. , Salzer John J. , Gronwall Caryl , Williams Anna L. 
Published: September 2023

Abstract
We derive oxygen abundances for two samples of Seyfert 2 (Sy2) active galactic nuclei (AGNs) selected from the KPNO International Spectroscopic Survey (KISS). The two samples from KISS include 17 intermediate-redshift (0.29 ≤ z ≤ 0.42) Sy2s detected via their [O iii] lines, and 35 low-redshift (z ≤ 0.1), Hα-detected Sy2s. The primary goal of this work is to explore whether the metallicity distribution of these two samples changes with redshift. To determine the oxygen abundances of the KISS galaxies, we use Cloudy to create a large number of photoionization model grids by varying the temperature of the accretion disk, the ratio of X-ray to UV continuum light, the ionization parameter, the hydrogen density, and the metallicity of the narrow-line region clouds. We link the results of these models to the observed [O iii]/Hβ and [N ii]/Hα emission-line ratios of the KISS sample on a Baldwin–Philips–Terlevich diagram, interpolating across the model grids to derive metallicity. The two redshift samples overlap substantially in terms of derived metal abundances, but we find that some of the intermediate-redshift Sy2s possess lower abundances than their local universe counterparts. Our analysis provides evidence for modest levels of chemical evolution (0.18 ± 0.06 dex) over 3–4 Gyr of look-back time. We compare our results to other AGN abundance derivation methods from the literature.

Abstract
The study of solar wind charge exchange (SWCX) emission is vital to both the X-ray astrophysics and heliophysics communities. SWCX emission contaminates all astrophysical observations in X-rays regardless of the direction. Ignoring this contribution to X-ray spectra can lead to erroneous conclusions regarding the astrophysical plasmas along the line of sight owing to the similar spectral distributions of SWCX and several common types of more distant astrophysical plasmas. Since its discovery, the literature has distinguished between diffuse SWCX emission resulting from solar wind–neutral interactions within Earth’s magnetosphere, called magnetospheric SWCX, and similar interactions occurring more generally throughout the heliosphere, called heliospheric SWCX. Here we build on previous work validating a modeling method for the heliospheric SWCX contribution in X-ray spectra obtained with a medium-resolution CubeSat instrument named HaloSat at low ecliptic latitudes. We now apply this model to a specially designed set of extended observations with the same instrument and successfully separate the spectral contributions of the astrophysical background and the heliospheric SWCX from the remaining contributions. Specifically, we find significant excess emission for four observations in the O vii emission line not explained by other sources, possibly indicative of magnetospheric SWCX. We discuss these results in comparison with simulation results publicly available through the Community Coordinated Modeling Center. We also report an absorbed high-temperature component in 2 of the 12 fields of view analyzed.
Grids of Wolf–Rayet Stars Using MESA with the k − ω Model: From 25 to 120 M
⊙ at Z = 0.02
Authors: Li 李 Zhi 志 , Li 李 Yan 焱 
Published: September 2023

Abstract
To explore overshoot mixing and rotational mixing beyond the convective core during the core He-burning phase in massive stars, we computed a grid of stellar models, both rotating and nonrotating, with the k − ω model at Z = 0.02, covering a mass range of 25–120 M
⊙. The rotating models start with a rotation rate of v
ini/v
crit = 0.4 at the zero-age main sequence, and the evolution is computed until the end of the central carbon-burning phase. Models with the k − ω model provide larger convective cores and a broadening of the main-sequence width. The diffusive-overshoot models with f
ov = 0.027 are, on average, closer to the k − ω models for massive stars at Z = 0.02, particularly for the stars with masses greater than 40 M
⊙. The final masses of the Wolf–Rayet (WR) stars range from 9.5–17.5 M
⊙ and 10–23 M
⊙ for the rotating and nonrotating models, respectively. In the rotating models, the C/N ratio decreases slowly below 0.1 outside the convective core, resulting in a flatter element transition region. In addition, the lifetimes of the WNC phase are 1–4 × 104 yr, which is about 1 order of magnitude longer than that in the nonrotating models. The masses of the WNC stars are dominated by internal mixing processes and the maximum masses of the He-burning convective cores during the core He-burning phase are in the range of 15–35 M
⊙. The expected WNC/WR ratios are 0.059 and 0.004 for the rotating and nonrotating models, respectively.
Influence of Heliobond on Microtensile Bond Strength of a New BIS-GMA Free Versus BIS-GMA Containing Composite Resin Restoration
Authors: Elsebaey Labib , Dowidar Weam , Alahmed Bader , Elmarakby Ahmed Mohamed 
Published: September 2023

AIM: The main objective of this study was to assess the micro-tensile bond strength (µTBS) of a free bisphenol-a-diglycidyl-ether-dimethacrylate (Bis-GMA) resin composite restorative material compared to a Bis-GMA-containing resin composite following the application of a hydrophobic coating (heliobond).
MATERIALS AND METHODS: A flat occlusal dentin surface was exposed in a total of eighty extracted teeth that were removed for periodontal reasons. Teeth were divided into two main equal groups according to the type of applied filling materials: BIS-GMA-free versus BIS-GMA-containing resin composite (n = 40). Each main group was subdivided into two equal subgroups (n = 20) according to the application of Heliobond (hydrophobic resin coating). Heliobond has been applied after adhesive application and before resin composite application. The first group was restored by a Free Bis-GMA Resin Composite (Admira, Voco, Germany); the second group was restored by a Bis- GMA-containing resin composite (Grandio, Voco, Germany). Each tested restorative material was applied and cured according to the manufacturer’s instructions.
RESULTS: Regardless of different composite and adhesive types, there was a statistically significant difference (p < 0.05) among all subgroups. Specimens with Heliobond recorded a higher µTBS mean value (30.46 ± 6.7 megapaskal [MPa]) than groups without Heliobond, which recorded µTBS mean value (23.95 ± 9.02 MPa).
CONCLUSION: Application of an extra hydrophobic layer coating (Heliobond) has improved the performance of the µTBS of the adhesive systems utilized with the new BIS-GMA-free versus BIS-GMA-containing composite resin
An illustrated atlas of the vertebral morphology of extant non-caenophidian snakes, with special emphasis on the cloacal and caudal portions of the column
Authors: Szyndlar Zbigniew , Georgalis Georgios L. 
Published: September 2023

AbstractWe here present a thorough documentation of the vertebral morphology and intracolumnar variation across non-caenophidian snakes. Our studied sample of multiple individuals covers a large number of genera (67) and species (120), pertaining to almost all extant non-caenophidian families. Detailed figuring of multiple vertebrae across the trunk, cloacal, and caudal series for many different individuals / taxa documents the intracolumnar, intraspecific, and interspecific variation. An emphasis is given in the trunk-to-caudal transition and the pattern of the subcentral structures in that region of the column. Extant non-caenophidian snakes show an astonishing diversity of vertebral morphologies. Diagnostic vertebral features for extant families and many genera are given, though admittedly vertebral distinction among genera in certain groups remains a difficult task. A massive compilation of vertebral counts for 270 species, pertaining to 78 different genera (i.e., almost all known valid genera) and encompassing all extant non-caenophidian families, is provided based on our observations as well as an extensive literature overview. More particularly, for many taxa, detailed vertebral counts are explicitly given for the trunk, cloacal, and caudal portions of the column. Extant non-caenophidian snakes witness an extremely wide range of counts of vertebrae, ranging from 115 up to 546. A discussion on the diagnostic taxonomic utility and potential phylogenetic value of certain vertebral structures is provided. Comparisons of the subcentral structures of the cloacal and caudal vertebral series are also made with caenophidian lineages. We anticipate that this illustrative guide will set the stage for more vertebral descriptions in herpetological works but will also be of significant aid for taxonomic identifications in ophidian palaeontology and archaeozoology.
La puissance des céréales
Authors: Stanziani Alessandro 
Published: September 2023

Tous les empires dans l’histoire ont pu faire ce constat : la puissance n’est pas seulement une question d’armement, mais aussi de contrôle des céréales. Elles ont constitué, jusqu’à l’essor de la consommation de viande, le carburant du travail humain. Cet article permet une charnière bienvenue entre histoire et actualité (« pénurie » et déstabilisation des marchés mondiaux des céréales avec la guerre d’Ukraine). Il retrace l’histoire longue des marchés des céréales dans le monde, les successions des politiques visant leur contrôle (stockage, contrôle des prix, blocage des approvisionnements) ou donnant libre cours à la spéculation, les effets de ces cycles sur les famines et les guerres. Ce qui spécifie le « nouveau capitalisme agraire » contemporain depuis les années 1980, c’est la spéculation totalement dérégulée sur les céréales : marchés virtuels, futures , accaparement des terres, contrôle du vivant et monopoles des semences, entrée de nouveaux acteurs comme banques, fonds de pension, hedge funds . L’auteur propose en conclusion quelques options politiques pour lutter contre cette hégémonie.
Trois interrogations sur les activités d’élevage
Authors: Larrère Raphaël 
Published: September 2023

Les activités d’élevage sont depuis des décennies fortement remises en cause pour leurs effets sur l’environnement et la concurrence qu’elles exercent sur l’accès à la terre, de grandes surfaces étant dans le monde dédiées à l’alimentation animale (maïs, soja). L’auteur montre les ambivalences des problématiques d’élevage en discutant trois questions. L’élevage représente-t-il un handicap pour nourrir le monde ? L’élevage contribue-t-il à l’érosion de la biodiversité ? L’élevage nuit-il à la santé ? En relativisant et contextualisant ces trois assertions, l’auteur désigne les méfaits de l’élevage industriel et plaide pour une démarche d’agro-écologie associant élevage et cultures. Mais il exprime ses craintes quant à la poursuite de la tendance actuelle.
L’agriculture rêve-t-elle de moutons électriques ?
Authors: Oui Jeanne 
Published: September 2023

Face aux pollutions environnementales causées par les pratiques productivistes, le modèle de l’« agriculture de précision » s’est développé depuis les années 1990 : des capteurs, des satellites, des GPS et des algorithmes permettraient de diminuer les dégâts écologiques causés par les activités de production. Au-delà des pratiques sur les exploitations, « agriculture digitale », « smartfarming » et autres « AgTech » sont devenus des termes quotidiens pour les organismes et les politiques agricoles. L’article propose de s’interroger sur l’argumentaire environnemental entourant ces outils numériques et leur développement, en mettant en avant les enjeux politiques, techniques et commerciaux inhérents à ce déploiement.
La lutte pour l’usage des terres à Notre-Dame-des-Landes
Authors: De Roo Priscilla 
Published: September 2023

Au-delà d’une bataille écologique tenace pour l’abandon du projet d’aéroport, le bocage de Notre-Dame des Landes a constitué un terrain d’expérimentation pour transformer l’occupation militante en droit pérenne d’usage des terres. Les « zadistes » se sont battus pour devenir agriculteurs et exploiter collectivement la terre au service d’une agriculture « écolo et non Monsanto ». Ils ont parié sur le fait de mener une bataille sur le droit face à l’administration et, en échange de fiches de projets, ont obtenu des baux ruraux individuels de neuf ans, comme les paysans résistants et les paysans cumulards, qui exploitaient les terres avant la préemption. Le rêve éveillé est devenu réalité, même si l’un des principes de base initiaux, « la terre en commun », a subi des altérations.
Subsistance
Authors: Pruvost Geneviève 
Published: September 2023

Le « féminisme de la subsistance », à l’intersection du féminisme, de l’écologie et de l’anticapitalisme, a été remis en lumière par des théoricien·nes et activistes du Nord et du Sud dans les années 2010. L’étude des sociétés paysannes montre que l’accomplissement par les femmes des tâches vitales pour le groupe a été sous-estimé et leur confère puissance, sacralité et autonomie, en particulier pour assurer l’égale répartition des biens de subsistance. Face aux critiques dénonçant cet essentialisme, l’auteure propose un « écoféminisme vernaculaire » qui s’appuie sur les pratiques concrètes des femmes intégrant agriculture, artisanat, travaux de mécanique et de maçonnerie, agirs familiaux. Car, sous sa forme moderne, le travail domestique est doublement aliéné : non seulement, il n’est pas rémunéré, mais il est coupé de ses potentialités productives de subsistance pour se cantonner à la consommation et au care . Les écoféministes de la subsistance veulent s’opposer aux vocations « naturelles » des femmes et imaginer des perspectives : se réapproprier et partager collectivement des fonctions nourricières de base dans un monde où s’impose de façon accélérée l’aménagement agro-industriel de la planète.

Formes de coordination professionnelle et coopération interpersonnelle en maison d’assistantes maternelles
Authors: Garnier Pascale , Bouve Catherine , Janner-Raimondi Martine 
Published: September 2023

Instituées en 2010, les maisons d’assistantes maternelles (Mam) permettent à des professionnelles de se regrouper pour accueillir des jeunes enfants (0-3 ans) dans un local distinct de leur domicile. Ces lieux représentent des formes d’hybridation entre des accueils individuels et collectifs. Cet article vise à les analyser en lien avec les modalités d’organisation du travail en Mam, en distinguant la coordination entre assistantes maternelles, fondée sur une division fonctionnelle du travail, de leur collaboration, s’appuyant sur leurs relations interpersonnelles. L’enquête empirique, réalisée en 2020-2021 dans six Mam aux caractéristiques très contrastées, comprend notamment un travail d’observation in situ , des entretiens individuels avec toutes les professionnelles des Mam et avec des acteurs de leur environnement local. L’analyse des différentes tâches des assistantes maternelles rend compte de la singularité de chaque Mam, parce qu’elle révèle la manière dont ces deux logiques de coordination et de collaboration se confortent ou s’opposent, modelées par les trajectoires des assistantes maternelles et leurs modalités d’accompagnement local.
Le tourisme réflexif en montagne à l’heure de l’Anthropocène : discussion autour du projet de réhabilitation du Montenvers, Chamonix
Authors: Salim Emmanuel , Girault Camille , Nesur Kalpana 
Published: September 2023

L’entrée dans l’Anthropocène, défini comme l’ère dans laquelle les activités humaines deviennent des forces à même d’influencer le climat et l’environnement à l’échelle planétaire, induit de nombreuses questions pour le tourisme. S’ils ne sont pas les seuls, les sites touristiques glaciaires, et les pratiques afférentes, se transforment avec leur environnement. Ces transformations posent la question de l’influence du changement climatique sur les motivations des acteurs touristiques et permettent d’envisager plus spécifiquement l’avènement d’un tourisme réflexif. Entendu comme une prise de conscience par les touristes eux-mêmes des enjeux – ici, environnementaux – soulevés par les modes de vie actuels, le tourisme réflexif permet plus largement d’aborder les contradictions auxquelles sont confrontées les sociétés dans le cadre des défis de la transition écologique. À travers l’analyse de la mise en œuvre du projet de réhabilitation de l’un des sites glaciaires les plus connus de France, le Montenvers et sa Mer de Glace, cet article entend interroger les logiques du développement touristique d’un tel site tout en soulignant ses contradictions. Les entretiens menés avec les parties prenantes du site et du projet montrent une tension claire entre une logique de durabilité menant au tourisme réflexif et une logique économique d’investissement et de quête de rentabilité. Au-delà de ce cas d’étude, ce travail questionne plus généralement la figure du tourisme comme symbole des contradictions sociétales entre discours et pratiques à l’heure de l’Anthropocène.
Jagged1 Acts as an RBP-J Target and Feedback Suppresses TNF-Mediated Inflammatory Osteoclastogenesis
Authors: Ng Courtney , Qin Yongli , Xia Yuhan , Hu Xiaoyu , Zhao Baohong 
Published: September 2023

Abstract
TNF plays a crucial role in inflammation and bone resorption in various inflammatory diseases, including rheumatoid arthritis (RA). However, its direct ability to drive macrophages to differentiate into osteoclasts is limited. Although RBP-J is recognized as a key inhibitor of TNF-mediated osteoclastogenesis, the precise mechanisms that restrain TNF-induced differentiation of macrophages into osteoclasts are not fully elucidated. In this study, we identified that the Notch ligand Jagged1 is a previously unrecognized RBP-J target. The expression of Jagged1 is significantly induced by TNF mainly through RBP-J. The TNF-induced Jagged1 in turn functions as a feedback inhibitory regulator of TNF-mediated osteoclastogenesis. This feedback inhibition of osteoclastogenesis by Jagged1 does not exist in RANKL-induced mouse osteoclast differentiation, as RANKL does not induce Jagged1 expression. The Jagged1 level in peripheral blood monocytes/osteoclast precursors is decreased in RA compared with the nonerosive inflammatory disease systemic lupus erythematosus, suggesting a mechanism that contributes to increased osteoclast formation in RA. Moreover, recombinant Jagged1 suppresses human inflammatory osteoclastogenesis. Our findings identify Jagged1 as an RBP-J direct target that links TNF and Notch signaling pathways and restrains TNF-mediated osteoclastogenesis. Given that Jagged1 has no effect on TNF-induced expression of inflammatory genes, its use may present a new complementary therapeutic approach to mitigate inflammatory bone loss with little impact on the immune response in disease conditions.
In vitro effect of anodization of titanium abutments on their tensile bond strength to implant-supported lithium disilicate all-ceramic crowns
Authors: Pour Hamed Karimi , Ansari Homeira , Tehrani Azita Mazaheri 
Published: September 2023

Background:
The retention of cement-retained implant-supported restorations can be affected by surface treatments such as anodizing. This study aimed to assess the effect of the anodization of titanium abutments on their tensile bond strength to implant-supported lithium disilicate (LDS) all-ceramic crowns.

Materials and Methods:
This in vitro, experimental study was conducted on 26 straight abutments in two groups of anodization and control. In the anodization group, seven flat 9 V batteries connected in series were used to generate 64 V energy. A glass container was filled with 250 mL of distilled water, and 1 g of trisodium phosphate was added to it to create an electrolyte solution. The anode was then disconnected and the abutment was rinsed with acetone and deionized water. The surface roughness of abutments was measured by a profilometer. The abutments were scanned by a laboratory scanner, and maxillary central incisor monolithic crowns were fabricated by inLab SW18 software. The crowns were seated on the abutments and temporarily cemented with TempBond. They were then incubated in artificial saliva and subjected to 5000 thermal cycles. The tensile bond strength of crowns was then measured. Data were analyzed by the Student's t-test and Mann–Whitney U-tests (α =0.05).

Results:
The mean bond strength was significantly higher in anodized abutments (P = 0.003). The surface roughness of anodized abutments was slightly, but not significantly, higher than that of the control group (P > 0.05). The frequency of adhesive failure was almost twice higher in anodized abutments.

Conclusion:
Anodization of titanium abutments significantly improved their tensile bond strength to implant-supported LDS all-ceramic crowns.
Effect of a novel rotation coordinating device on registered horizontal condylar guidance of nonarcon semi-adjustable articulators
Authors: Manshaee Farbod , Najatidanesh Farahnaz , Savabi Omid , Atash Ramin 
Published: September 2023

Background:
Horizontal condylar guidance (HCG) is registered by protrusive interocclusal records but in nonarcon articulators, these records can affect the accuracy. The present study aimed to evaluate the effect of a novel rotation coordinating device (RCD) on condylar guidance setting with protrusive interocclusal records.

Materials and Methods:
The study was designed as a comparative in-vitro investigation. Stone maxillary and mandibular casts were mounted on a fully adjustable instrument as the patient. Duplicate casts were mounted on an arcon and a nonarcon articulator with corresponding face bow records and in maximum intercuspation relation. Five different condylar guidance inclinations for both sides (20°, 30°, 40°, 50°, and 60°) were set on the fully adjustable instrument and 16 protrusive interocclusal records were established at each setting. HCG was set for arcon, nonarcon articulators, and nonarcon articulators with RCD. Data were analyzed using one-sample t-test to compare with actual HCG and one-way analysis of variance (α =0.05).

Results:
Mean HCG for studied articulators was 35.40 for arcon, 30.31 for nonarcon without RCD, and 35.61 for nonarcon with RCD which were significantly different from actual HCG (P < 0.05). HCG of the nonarcon with RCD showed no significant difference with arcon articulator (P = 0.71) while both were significantly different from nonarcon without RCD (P < 0.001).

Conclusion:
“The RCD” compensates the condylar guidance inclination difference between arcon and nonarcon articulators. The device precisely transfers the hinge movement of the upper member of the articulator to the condylar track.
