Calculation of reinforced concrete structures: considerations on developing new theory (continued)
Authors: Nazarenko V. G. , Zvezdov A. I. , Larionov E. A. 
Published: October 2023

Introduction. The authors develop the results of their previously published study in order to build up a nonlinear dissipative theory of concrete compressive strength. The present paper explores possibilities to improve the theory of calculation of concrete and reinforced concrete structures in the light of the accumulated knowledge.Aim. To introduce an approach to developing a nonlinear dissipative theory of concrete compressive strength in the absence of regulatory documents for loading modes, using instead the standard classification of loads.Results. The authors refer to the non-linear hereditary creep theory as the most accurate but time-consuming, and keeping its positive properties, reduce its equation of state to the equation of ageless concrete with its simplicity in application. In addition, the equation of state of concrete is solved in elementary functions and closed form in practically important cases.The overwhelming majority of published scientific data on the behavior of creep curves in the area of reliable performance of reinforced concrete structures indicates smoothness and continuity of the curves. Considering that, the data obtained in short-term tests can be extended to the whole time interval, thus providing possibility for express analyses of the strain properties of concrete.The study estimated the reversibility of creep strain and found out dissipativity of elastic strain. The authors established a nonlinear relation between strain and constant stress and introduced an approach to developing a nonlinear dissipative theory of concrete compressive strength in the absence of regulatory documents for loading modes, using instead the standard classification of loads.Conclusions. The considered experimental data were recognized to provide qualitative information due to their apparent deficit. In order to obtain quantitative evaluation, the experiments should be reproduced a sufficient number of times.

within the Romulus25 cosmological hydrodynamic simulation. Using mock-observation methods, we identify isolated dwarf galaxies with quenched star formation and make direct comparisons to the quenched fraction in the NASA Sloan Atlas (NSA). Similar to other cosmological simulations, we find a population of quenched, isolated dwarf galaxies below M

⊙ not detected within the NSA. We find that the presence of massive black holes (MBHs) in Romulus25 is largely responsible for the quenched, isolated dwarfs, while isolated dwarfs without an MBH are consistent with quiescent fractions observed in the field. Quenching occurs between z = 0.5–1, during which the available supply of star-forming gas is heated or evacuated by MBH feedback. Mergers or interactions seem to play little to no role in triggering the MBH feedback. At low stellar masses, M

star ≳ 109.3
M
⊙, quenching occurs rapidly within 1 Gyr, with the MBH evacuating gas from the central few kpc of the galaxy and driving it to the outskirts of the halo. Our results indicate the possibility of substantial star formation suppression via MBH feedback within dwarf galaxies in the field. On the other hand, the apparent overquenching of dwarf galaxies due to MBH suggests that higher-resolution and/or better modeling is required for MBHs in dwarfs, and quenched fractions offer the opportunity to constrain current models.

Published: October 2023

Abstract
The nonlocal thermodynamical equilibrium (NLTE) line formation of Y i and Y ii is considered in 1D LTE model atmospheres of FGK-type stars. The model atom was constructed with the most up-to-date atomic data, including quantum cross sections and rate coefficients for transitions in inelastic collisions of Y i and Y ii with hydrogen atoms. For seven reference stars, we obtained an agreement between NLTE abundances inferred from the two ionization stages, while the difference in LTE abundance (Y i and Y ii) can reach up to −0.31 dex. In the atmospheres of FGK-type stars, for both Y i and Y ii lines, the NLTE abundance corrections are positive. In solar metallicity stars, the NLTE abundance corrections for Y ii lines do not exceed 0.12 dex, while in atmospheres of metal-poor stars, they do not exceed 0.21 dex. For Y i lines, the NLTE abundance corrections can reach up to ∼0.5 dex. We determined the yttrium NLTE abundances for a sample of 65 F and G dwarfs and subgiants in the −2.62 ≤ [Fe/H] ≤ +0.24 metallicity range, using high-resolution spectra. For stars with [Fe/H] ≤ −1.5, [Y/Fe] versus [Fe/H] diagram reveals a positive trend with an average value of [Y/Fe] ≃ 0. For metal-poor stars, among Sr, Y, and Zr, the arrangement [Sr/Fe] < [Y/Fe] < [Zr/Fe] remains consistent. The current study is useful for Galactic chemical evolution research. The model atom will be applied for NLTE yttrium abundance determination in very metal-poor stars studied with LAMOST and Subaru.

. The expected velocity dispersion of NGC 1052-DF4 from the stellar mass alone is 7 ± 1 km s−1, and for a Navarro–Frenk–White (NFW) halo that follows the stellar mass–halo mass relation and the halo mass–concentration relation, the expectation is ∼30 km s−1. The low velocity dispersion rules out a normal NFW dark matter halo, and we confirm that NGC 1052-DF4 is one of at least two galaxies in the NGC 1052 group that have an anomalously low dark matter content. While any viable model for their formation should explain the properties of both galaxies, we note that NGC 1052-DF4 now poses the largest challenge, as it has the most stringent constraints on its dynamical mass.

Abstract
The launch of JWST opens a new window for studying the connection between metal-line absorbers and galaxies at the end of the Epoch of Reionization. Previous studies have detected absorber–galaxy pairs in limited quantities through ground-based observations. To enhance our understanding of the relationship between absorbers and their host galaxies at z > 5, we utilized the NIRCam wide-field slitless spectroscopy to search for absorber-associated galaxies by detecting their rest-frame optical emission lines (e.g., [O III] + Hβ). We report the discovery of a Mg ii-associated galaxy at z = 5.428 using data from the JWST ASPIRE program. The Mg ii absorber is detected on the spectrum of quasar J0305–3150 with a rest-frame equivalent width of 0.74 Å. The associated galaxy has an [O III] luminosity of 1042.5 erg s−1 with an impact parameter of 24.9 pkpc. The joint Hubble Space Telescope–JWST spectral energy distribution (SED) implies a stellar mass and star formation rate of M
* ≈ 108.8
M
⊙, star-formation rate ≈ 10 M
⊙ yr−1. Its [O III] equivalent width and stellar mass are typical of [O III] emitters at this redshift. Furthermore, connecting the outflow starting time to the SED-derived stellar age, the outflow velocity of this galaxy is ∼300 km s−1, consistent with theoretical expectations. We identified six additional [O III] emitters with impact parameters of up to ∼300 pkpc at similar redshifts (∣dv∣ < 1000 km s−1). The observed number is consistent with that in cosmological simulations. This pilot study suggests that systematically investigating the absorber–galaxy connection within the ASPIRE program will provide insights into the metal-enrichment history in the early Universe.
Unveiling the Nature of Galactic TeV Sources with IceCube Results
Authors: Vecchiotti V. , Villante F. L. , Pagliaroli G. 
Published: October 2023

Abstract
IceCube collaboration reported the first high-significance observation of the neutrino emission from the Galactic disk. The observed signal can be due to diffuse emission produced by cosmic rays interacting with interstellar gas but can also arise from a population of sources. In this paper, we evaluate both the diffuse and source contribution by taking advantage of gamma-ray observations and/or theoretical considerations. By comparing our expectations with IceCube measurements, we constrain the fraction of Galactic TeV gamma-ray sources (resolved and unresolved) with hadronic nature. In order to be compatible with the IceCube results, this fraction should be small, or the source proton energy cutoff should be well below the cosmic-ray proton knee. In particular, for a cutoff energy equal to 500 TeV, the fraction of hadronic sources should be less than ∼40% corresponding to a cumulative source flux Φ
ν,s ≤ 2.6 × 10−10 cm−2 s−1 integrated in the 1–100 TeV energy range. This fraction reduces to ∼20% for energy cutoff reaching the cosmic-ray proton knee around 5 PeV.
An Extremely Massive White Dwarf Escaped from the Hyades Star Cluster

Published: October 2023

Abstract
We searched the Gaia DR3 database for ultramassive white dwarfs with kinematics consistent with having escaped the nearby Hyades open cluster, identifying three such candidates. Two of these candidates have masses estimated from Gaia photometry of approximately 1.1 solar masses; their status as products of single-stellar evolution that have escaped the cluster was deemed too questionable for immediate follow-up analysis. The remaining candidate has an expected mass >1.3 solar masses, significantly reducing the probability of it being an interloper. Analysis of follow-up Gemini GMOS spectroscopy for this source reveals a nonmagnetized hydrogen atmosphere white dwarf with a mass and age consistent with having formed from a single star. Assuming a single-stellar-evolution formation channel, we estimate a 97.8% chance that the candidate is a true escapee from the Hyades. With a determined mass of 1.317 solar masses, this is potentially the most massive known single-evolution white dwarf and is by far the most massive with a strong association with an open cluster.
Spider fauna (Arachnida, Araneae) in Mordovia State Nature Reserve and National Park “Smolny” (Russia)

Published: October 2023

Ecosystems in protected areas are richer in animal and plant species diversity ("biodiversity hotspots") due to more stringent conservation conditions. Of particular importance is scientific research and monitoring of this diversity in such areas. The aim of this study is to describe a set of data on Araneae occurrence in two protected areas: Mordovia State Nature Reserve and National Park "Smolny".
About 29,000 individuals are identified to the species level. In total, 342 species were recorded for both PAs. The greatest species diversity was recorded in the families Linyphiidae (109 species; 32%), Lycosidae (38 species; 11%) Gnaphosidae (28 species; 8%), Araneidae (25 species; 7%), Salticidae (24 species; 7%), Thomisidae (23 species; 7%) and Theridiidae (22 species; 6% from total species diversity). The five species most abundant in the lower stratum (litter and moss layer) of biocenoses were Diplocephalus picinus, Microneta viaria, Tenuiphantes tenebricola, Diplostyla concolor and Abacoproeces saltuum and the five species most abundant in the vegetative stratum (herb, shrub and tree stems and canopy) were Linyphia triangularis, Enoplognatha ovata, Evarcha falcata, Misumena vatia and Evarcha arcuata. The dataset contains information on the occurrence of seven rare species (Centromerus nurgush, Centromerus persimilis, Diplocephalus dentatus, Entelecara flavipes, Metapanamomops kaestneri, Pelecopsis radicicola and Porrhomma microcavense), three species (Agalenatea redii, Neoscona adianta, Thanatus oblongiusculus) that entered here from the steppe zone and two synanthropic species (Steatoda castanea, Tegenaria domestica).
Usage des liaisons variables dans deux corpus de lecture
Authors: Dugua Céline 
Published: October 2023

Notre travail porte sur l’usage des liaisons variables en lecture et, plus spécifiquement, dans la lecture d’ouvrages destinés aux enfants, à partir de deux corpus : un module du corpus eslo , portant sur des lectures partagées entre adultes et enfants (30 histoires lues), et la lecture d’un même conte ( Pierre et le loup ) par 79 lecteurs comparée à celle réalisée par B. Giraudeau dans un livre audio (Pustka 2017). La complémentarité de ces deux corpus permet de mieux cerner l’influence de l’accès aux formes graphiques des mots sur la réalisation des liaisons et également de rendre compte des différents facteurs qui font varier cet usage.
Le rôle de l’usage dans l’acquisition de la liaison : production et perception d’élèves franco-germanophones bilingues
Authors: Heiszenberger Elisabeth 
Published: October 2023

L’objectif de la présente étude est de tester l’influence de la fréquence sur l’acquisition de la liaison dans une nouvelle population, soit chez 49 enfants et adolescents bilingues franco-germanophones différant par leur temps d’exposition au français. L’étude montre que, même si les enfants bilingues présentent les mêmes trajectoires d’acquisition que les enfants monolingues, les phases développementales diffèrent de celles observées chez ces derniers. Toutefois, le développement semble être nettement hétérogène : plus la compétence linguistique est élevée, plus le développement de la liaison est avancé. La présente étude fournit donc de nouveaux arguments pour les approches basées sur l’usage mais souligne la présence d’autres facteurs qui entrent en jeu, à savoir la scolarisation ou l’enseignement explicite de la liaison.

Published: October 2023

L’objectif de ce travail est de commenter les résultats d’un test d’acceptabilité administré à une population de jeunes collégiens. Poursuivant un travail déjà entamé sur la perception de la liaison et les représentations subjectives (Laks & Floquet 2017 ; Celata, De Flaviis & Floquet 2020 ; De Flaviis 2021), nous nous intéressons aussi bien à la compétence épiphonologique qu’à la conscience métaphonologique de deux groupes d’adolescents de Toulouse et Menton. Nos premiers résultats vont dans le sens d’une divergence entre ce que le chercheur trouve dans un corpus et ce que l’auditeur naïf perçoit de son côté surtout en ce qui concerne le statut de la liaison.
Indexicalité et interprétation du monde social : une analyse socio-pragmatique de la liaison variable
Authors: Martin Alexander , Abbou Julie , Burnett Heather 
Published: October 2023

Des travaux antérieurs ont souligné un lien fort entre liaison variable et écrit mais n’ont pas développé une analyse explicite de ce lien. Dans cet article, nous proposons un cadre théorique basé sur la sociologie pragmatique (Boltanski & Thévenot 1991) qui permet de rendre compte des sens sociaux qui émergent lors de la réalisation de la liaison variable en situation. En esquissant un champ indexical de l’écrit, nous proposons que plusieurs ensembles de sens soient potentiellement en jeu lors de la réalisation d’une liaison variable. Grâce à un test expérimental basé sur la Matched Guise Technique , où face à des scénarios décrivant des échanges sociaux, les participants devaient indiquer leur préférence pour la liaison réalisée ou non. Nous montrons que la liaison variable prend sens notamment dans le « monde industriel » où le professionnalisme est valorisé et peut évoquer la préparation derrière un texte écrit.
Un retrato de Ptolomeo III Evergetes, procedente de colonia Patricia (Córdoba, España)
Authors: Loza Azuaga María Luisa , Beltrán Fortes José 
Published: October 2023

Se estudia un herma de un personaje masculino, adquirido por el Museo Arqueológico y Etnológico de Córdoba en la década de 1970. Procede de un descubrimiento ocasional en la calle Ángel de Saavedra, en los Altos de Santa Ana. Ha sido interpretado como monarca helenístico o atleta, de manera genérica, así como representación del dios Hermes. En este artículo lo identificamos como retrato idealizado del monarca lágida Ptolomeo III Evergetes, tanto por sus rasgos fisonómicos, como especialmente por el atributo que debió llevar en el centro de la diadema, una hoja o flor de loto, simbolizando su vinculación con Egipto, aunque hoy no se conserva y solo presenta el rebaje y orificio donde se ajustaría. Sería elaborado en un taller oriental (Ática) en época de Augusto.
“Conheceis a verdade, e a verdade vos libertarás”: teoria da conspiração ambiental-climática e populismo no início do governo Bolsonaro (2018-2020)
Authors: Behr Klaus Ramalho von 
Published: October 2023

O argumento principal defendido neste artigo é o
de que as teorias da conspiração ambiental-climáticas propagadas no
início do governo Bolsonaro ajudaram a fomentar uma ideologia
populista – isto é, a ideia de que há uma luta moral entre o ‘povo de
bem’ contra ‘elites corruptas’ e de que o líder populista é o único
representante legítimo deste povo porque representa seus valores
morais. Para sustentar este argumento, realizamos uma análise de
conteúdo qualitativa de 36 discursos conspiratórios em torno da
questão ambiental-climática proferidos por cinco atores da alta cúpula
do governo Bolsonaro (Jair Bolsonaro, Eduardo Bolsonaro, Ernesto
Araújo, Filipe Martins e Olavo de Carvalho) entre 2018 e 2020. A
partir dessa análise qualitativa, evidenciamos uma estrutura
conspiratória da seguinte maneira: elites globais, intelectuais,
tecnocráticas e de esquerda buscam instrumentalizar a pauta
ambiental-climática – em especial via doutrinação ideológica e
alarmismo – para justificarem um controle generalizado sobre as
soberanias das nações e as liberdades dos indivíduos. Foi constatado
que desmascarar e resistir ao ambientalismo foram as duas mensagens
morais principais que essa estrutura conspiratória emana. Diante esta
luta moral entre a verdade e a liberdade, na qual as mudanças
climáticas e a Amazônia estão inseridas, Bolsonaro é apresentado como
líder patriótico que defende a soberania, o desenvolvimento e os
interesses do povo e da nação.
Effets d’une recherche collaborative basée sur un « dispositif d’écriture de type monographique »

Published: October 2023

Pendant une « recherche avec » centrée sur la relation pédagogique en cours d’espagnol, basée sur un dispositif inspiré des groupes d’écriture monographique et ancrée dans l’approche clinique d’orientation psychanalytique, une sorte d’homologie entre l’expérience au sein du groupe et les pratiques avec les groupes-classes a pu être repérée. Un travail sur l’accueil des singularités dans les classes semble s’être effectué tandis que s’élaborait l’émergence des singularités dans le groupe, grâce à une énonciation subjectivée réassurant les participants dans leur posture enseignante pour s’ouvrir à l’imprévu.
La formation d’animateur socioculturel : de l’Union européenne au marché local
Authors: Bock Cyrille 
Published: October 2023

Dans cet article, nous nous demandons dans quelle mesure l’éducation populaire s’inscrit dans le marché des nouvelles formations d’animateur. À ce titre, trois niveaux d’analyse sont proposés : tout d’abord, l’influence des directives européennes dans les formations, en particulier le processus de Bologne, afin d’appréhender l’influence de l’Union européenne sur les formations ; ensuite, les stratégies des pouvoirs publics en termes de plan de formation à l’échelle nationale dans le but de saisir les orientations nationales des formations ; enfin, l’interprétation des acteurs à un niveau local vise à mettre en lumière la place accordée à l’éducation populaire dans trois marchés locaux (Paris, Grenoble et Toulouse). L’intérêt est donc d’analyser l’influence des directives initiées par l’Union européenne sur les formations d’animateurs socioculturels. Par déclinaison, la place de l’éducation populaire est interrogée à la fois à travers les diplômes et les acteurs qui les proposent.
