POTENTIAL SOURCE ROCKS EVALUATION FOR THE PRE-SALT COMPLEX OF THE EASTERN EDGE OF PRECASPIAN BASIN
Authors:   SATBAYEV UNIVERSITY, 22 Satbayev Street, Almaty, 050000, Republic of Kazakhstan, ZHANSERKEYEVA A.A.
Published: October 2022

Through basin analysis, the major tectonic stages and paleogeographic conditions of the formation of potential oil and gas source rocks of the subsalt complex of the eastern side zone of the Precaspian basin are considered. Prediction and localization of potential source rocks is critical for the Precaspian petroleum system understanding, both during petroleum play assessment at the prospecting and exploration stages. The generation and emigration potential of the oil and gas basin is determined not only by the concentration of the initial organic matter in the rock, but also by the type of kerogen. Based on Rock-Eval studies and comparative analysis with published biomarker data, the generation potential, genetic type and thermal maturity are analyzed depending on the age and structural relatedness of potential source rocks. A high generation potential has been established for the Lower Permian deposits, the occurrence of multiple generation foci controlled by the type and concentration of organic matter is predicted, which led to the formation of specific reservoirs of the "akzharite" type. The generation potential of the Visean-Bashkirian deposits is poor to average, catagenetic unconformities have been established within KT-II, KT-I, which indicates erosions, the total organic carbon (TOC) is 0.1-4%, the hydrogen index increases with depth, for samples enriched with TOC and with a content of S2 > 1, type II kerogen has been established, which it is an indicator of reducing marine environment. 2D basin modeling was performed in order to reconstruct the thermal evolution of potential source rocks and their thermal maturity and transformation ratio were modelled to determine the regional characteristics of hydrocarbon generation and migration. It is assumed that the formation and distribution area of the primary source rocks is associated with reducing conditions of the deep-sea shelf and continental slope and intensive subsidence in the Late Devonian-Lower Permian times. Conducting a comprehensive analysis of paleogeographic and paleotectonic conditions for the formation of potential source rocks is of key importance in the seismic interpretation and reconstruction of thermal history. 2D basin modeling was performed in order to reconstruct the thermal history of potential oil-producing strata and the degree of catagenetic maturity and the kerogen maturity index were estimated to determine the regional characteristics of hydrocarbon generation and migration.
Suggestions for the Development Direction of the Aging-friendly Industry in Daegu Metropolitan City
Authors:   National Association of Korean Local Government Studies, Shim Sang-Gak , Kim Chang-One
Published: October 2022

If the proportion of population aged 65 or older exceeds 20%, it is called a "super-aged society," and according to the National Statistical Office's future population estimate, the proportion of population aged 65 or older reached 20.3% as of 2025. Accordingly, the government and local governments need to establish various policies according to the entry into an aging society. Korea is also aware of this situation and establishing and promoting policies for various elderly societies or elderly-friendly industries. However, there is a limitation in terms of policy efficiency as the approach to the situation or flow of the times is prioritized, not the multidimensional approach to the aging society and the aging-friendly industry. Therefore, this study suggested the direction of revitalization of the aging-friendly industry, policies, institutions, and corporate participation in the market sector through analysis of Japanese policies and markets that entered the aging society earlier than Korea. As a result of this study, it was confirmed that the elderly-friendly industry needs diversification of products and services and high added value accordingly, and business opportunities should be discovered and provided to products and services desired by the elderly. In addition, in terms of policy, the government and local governments need to make prior support policies for the elderly-friendly industry, and efforts for the interest and development of the elderly-friendly industry by local governments.
The Demographics of Kepler's Earths and Super-Earths into the Habitable Zone

Published: October 2022

Understanding the occurrence of Earth-sized planets in the habitable zone of Sun-like stars is essential to the search for Earth analogs. Yet a lack of reliable Kepler detections for such planets has forced many estimates to be derived from the close-in (2 < P
orb < 100 days) population, whose radii may have evolved differently under the effect of atmospheric mass-loss mechanisms. In this work, we compute the intrinsic occurrence rates of close-in super-Earths (∼1–2 R
⊕) and sub-Neptunes (∼2–3.5 R
⊕) for FGK stars (0.56–1.63 M
⊙) as a function of orbital period and find evidence of two regimes: where super-Earths are more abundant at short orbital periods, and where sub-Neptunes are more abundant at longer orbital periods. We fit a parametric model in five equally populated stellar mass bins and find that the orbital period of transition between these two regimes scales with stellar mass, like

. These results suggest a population of former sub-Neptunes contaminating the population of gigayear-old close-in super-Earths, indicative of a population shaped by atmospheric loss. Using our model to constrain the long-period population of intrinsically rocky planets, we estimate an occurrence rate of

Finally, we discuss our results in the context of future missions searching for habitable zone planets.
Solar-like to Antisolar Differential Rotation: A Geometric Interpretation
Authors: Camisassa Maria E. , Featherstone Nicholas A.
Published: October 2022

The solar convection zone rotates differentially, with its equatorial region rotating more rapidly than the polar regions. This form of differential rotation, also observed in many other low-mass stars, is understood to arise when Coriolis effects are stronger than those associated with buoyant driving of the convection. When buoyancy dominates, a so-called antisolar state of differential rotation results, characterized by rapidly rotating poles and a slow equator. The transition between these two states has been shown to occur when the intensity of these two forces is roughly equal or, equivalently, when the convective Rossby number of the system is unity. Here we consider an alternative view of the transition that relates this phenomenon to convective structure and convective-zone depth. Using a series of 3D rotating-convection-zone simulations, we demonstrate that the solar/antisolar transition occurs when the columnar convective structures characteristic of rotating convection attain a diameter roughly equivalent to the shell depth. When the characteristic convective wavelength exceeds twice the shell depth, we find that the coherent convective structures necessary to sustain an equatorward Reynolds stress are lost, and an antisolar state results. We conclude by presenting a force-balance analysis that relates this geometric interpretation of the transition to the convective Rossby-number criteria identified in previous studies.
MHD Simulation of Homologous Eruptions from Solar Active Region 10930 Caused by Sunspot Rotation
Authors: Wang Xinyi , Jiang Chaowei , Feng Xueshang , Duan Aiying , Bian Xinkai
Published: October 2022

The relationship between solar eruption and sunspot rotation has been widely reported, and the underlying mechanism needs to be studied. Here we performed a full 3D MHD simulation using a data-constrained approach to study the mechanism of flare eruptions in active region (AR) NOAA 10930, which is characterized by continuous sunspot rotation and homologous eruptions. We reconstructed the potential magnetic field from the magnetogram of Hinode/SOT as the initial condition and drove the MHD system by applying continuous sunspot rotation at the bottom boundary. The key magnetic structure before the major eruptions and the preformed current sheet were derived, which is responsible for the complex MHD evolution with multiple stages. The major eruptions were triggered directly by fast reconnection in the preformed current sheet above the main polarity inversion line between the two major magnetic polarities of the AR. Furthermore, our simulation shows the homologous eruption successfully. It has reasonable consistency with observations in relative strength, energy release, X-ray and Hα features, and time interval of eruptions. In addition, the rotation angle of the sunspot before the first eruption in the simulation is also close to the observed value. Our simulation offers a scenario different from many previous studies based on ideal instabilities of a twisted magnetic flux rope and shows the importance of sunspot rotation and magnetic reconnection in efficiently producing homologous eruptions by continuous energy injection and impulsive energy release in a recurrent way.
Protostellar and Protoplanetary Disk Masses in the Serpens Region

Published: October 2022

We present the results from an Atacama Large Millimeter/submillimeter Array (ALMA) 1.3 mm continuum and 12CO (J = 2 − 1) line survey spread over 10 deg2 in the Serpens star-forming region of 320 young stellar objects, 302 of which are likely members of Serpens (16 Class I, 35 flat-spectrum, 235 Class II, and 16 Class III). From the continuum data, we derive disk dust masses and show that they systematically decline from Class I to flat-spectrum to Class II sources. Grouped by stellar evolutionary state, the disk mass distributions are similar to other young (<3 Myr) regions, indicating that the large-scale environment of a star-forming region does not strongly affect its overall disk dust mass properties. These comparisons between populations reinforce previous conclusions that disks in the Ophiuchus star-forming region have anomalously low masses at all evolutionary stages. Additionally, we find a single deeply embedded protostar that has not been documented elsewhere in the literature and, from the CO line data, 15 protostellar outflows, which we catalog here.

We report the serendipitous discovery of an elliptical shell of CO associated with the faint stellar object SSTc2d J163134.1-240060 as part of the “Ophiuchus Disk Survey Employing ALMA” (ODISEA), a project aiming to study the entire population of protoplanetary disks in the Ophiuchus Molecular Cloud from 230 GHz continuum emission and 12CO (J = 2–1), 13CO (J = 2–1) and C18CO (J = 2–1) lines readable in Band 6. Remarkably, we detect a bright 12CO elliptical shape emission of ∼3″ × 4″ toward SSTc2d J163134.1-240060 without a 230 GHz continuum detection. Based on the observed near-IR spectrum taken with the Very Large Telescope (KMOS), the brightness of the source, its three-dimensional motion, and Galactic dynamic arguments, we conclude that the source is not a giant star in the distant background (>5–10 kpc) and is most likely to be a young brown dwarf in the Ophiuchus cloud, at a distance of just ∼139 pc. This is the first report of quasi-spherical mass loss in a young brown dwarf. We suggest that the observed shell could be associated with a thermal pulse produced by the fusion of deuterium, which is not yet well understood, but for a substellar object is expected to occur during a short period of time at an age of a few Myr, in agreement with the ages of the objects in the region. Other more exotic scenarios, such as a merger with planetary companions, cannot be ruled out from the current observations.

We analyze the cosmic-ray variations during a significant Forbush decrease observed with worldwide networks of ground-based neutron monitors and muon detectors during 2021 November 3–5. Utilizing the difference between primary cosmic-ray rigidities monitored by neutron monitors and muon detectors, we deduce the rigidity spectra of the cosmic-ray density (or omnidirectional intensity) and the first- and second-order anisotropies separately for each hour of data. A clear two-step decrease is seen in the cosmic-ray density with the first ∼2% decrease after the interplanetary shock arrival followed by the second ∼5% decrease inside the magnetic flux rope (MFR) at 15 GV. Most strikingly, a large bidirectional streaming along the magnetic field is observed in the MFR with a peak amplitude of ∼5% at 15 GV, which is comparable to the total density decrease inside the MFR. The bidirectional streaming could be explained by adiabatic deceleration and/or focusing in the expanding MFR, which have stronger effects for pitch angles near 90°, or by selective entry of GCRs along a leg of the MFR. The peak anisotropy and density depression in the flux rope both decrease with increasing rigidity. The spectra vary dynamically, indicating that the temporal variations of density and anisotropy appear different in neutron monitor and muon detector data.
Key Parameters Controlling the Photodesorption Yield in Interstellar CO Ice Analogs: The Influence of Ice Deposition Temperature and Thickness

Published: October 2022

The overabundance of gas molecules in the coldest regions of space points to a nonthermal desorption process. Laboratory simulations show the efficient desorption of CO ice that is exposed to ultraviolet radiation, known as photodesorption, which decreases with increasing ice deposition temperature. However, our understanding of this abnormal phenomenon still remains elusive. In this work, we show that the same phenomenon—and, in particular, a dramatic drop in the photodesorption yield—is observed when the deposition temperature is 19 K and higher. Also, the minimum ice thickness that accounts for a constant photodesorption yield of CO ice is dependent on the deposition temperature, an observation that is reported here for the first time. We propose that the key parameters dominating the absorbed photon energy transfer in CO ice, and contributing to the measured photodesorption yields, are the energy transfer length, the desorption yield contributed by a single ice layer, and the relative effective surface area. These parameters should be incorporated into astrophysical models that simulate the photodesorption of the top CO-rich ice layer in icy dust populations, with a size distribution that is related to the ice thickness.

Authors: Pereira de Farias Ruth Leia , Pelissari Monteiro Aguiar Baroni Mariana
Published: October 2022

O objetivo deste trabalho é relatar uma experiência de interação com alunos do 9º ano em uma escola municipal do estado de São Paulo com a plataforma educacional Hypatiamat, especificamente no que tange ao estudo relacionado ao teorema de Pitágoras. Essa pesquisa-ação foi desenvolvida com 24 alunos, mediados pelo professor, no laboratório de informática da escola e teve como finalidade principal acompanhar a evolução da aprendizagem dos participantes durante a utilização da plataforma. As etapas da pesquisa consistiram na aplicação de uma avaliação diagnóstica sobre o conteúdo relacionado ao teorema de Pitágoras, antes e após a interação dos alunos com a plataforma; na utilização desse recurso por um período de dez aulas nas quais foram acompanhados e medidos pelo professor pesquisador; e, por último, na aplicação de um questionário sobre a experiência vivenciada. Os resultados mostraram que a maioria dos estudantes, cerca de 87,49%, aprenderam satisfatoriamente o conteúdo proposto por meio da Plataforma Hypatiamat. A partir das respostas dos questionários foi possível perceber, também, que os estudantes gostaram e utilizariam novamente esse recurso durante as aulas, apesar de optarem frequentemente pelo método expositivo, típico do ensino tradicional, sobretudo quando a atividade requer habilidades mais complexas de leitura. Sendo assim, podemos concluir que a plataforma favoreceu e contribuiu com a aprendizagem dos alunos pois, por meio do acompanhamento e das avaliações realizadas pelo professor, verificamos que os alunos compreenderam os conceitos envolvidos nos exercícios e desenvolveram os cálculos corretamente.
O uso de recursos didáticos nas aulas de ciências das séries finais do ensino fundamental de uma escola pública em Viçosa do Ceará – CE
Authors: Alves Francisco Ailton Da Silva , Gomes Geovany Amorim
Published: October 2022

O presente trabalho foi realizado com o objetivo principal de identificar, junto a seis professores do Ensino Fundamental II de uma escola pública de Viçosa do Ceará – CE, os recursos didáticos mais utilizados no desenvolvimento de suas aulas de Ciências. Para obtenção das informações, foi aplicado um questionário aos professores, além da observação do espaço escolar com a finalidade de localizar os materiais didáticos disponíveis. Os resultados demonstraram que boa parte dos docentes se limita ao uso do livro didático e data show em suas aulas, além de considerarem este último instrumento como agente fomentador da motivação nos alunos. Ademais, a maioria possui entendimento parcial sobre a importância dos recursos didáticos no contexto escolar, bem como ignoram a grande diversidade de ferramentas instrucionais presentes na escola e desconhecem as vantagens em relação à confecção de materiais alternativos para a educação científica. Portanto, apesar da metade dos informantes serem habilitados para ensinar Ciências, sugere-se que a maior parte receba capacitação em curso de formação continuada com enfoque na questão das ferramentas pedagógicas. Com esse aperfeiçoamento profissional, espera-se que esses professores renovem suas práticas pedagógicas no seu local de trabalho, passando a construir seus próprios materiais de apoio e/ou aproveitando ao máximo aqueles oferecidos pela escola.
Dimensions of scientific literacy in the teaching practice of a teachers' group
Authors: Cogo Thaís Cristina , Leite Rosana Franzen
Published: October 2022

This current paper explores the teachers' reflections and ideas of the early years of an elementary school in Paraná state about their pedagogical practices in science teaching. The considerations here intend to describe and analyze scientific literacy (SL) aspects that are currently introduced in elementary school teachers' reports about teaching work and the relationship with science teaching. The data were acquired from semi-structured interviews in which constituted a report for each interviewed teacher. The reports were analyzed based on Lauren Bardin's Content Analysis, in particular the thematic analysis. Our results allowed us to reveal specific aspects from the pedagogical practices of the social actors involved, and also to analyze the school and the teachers understanding regarding the Natural Science area, besides demonstrating that the teachers show difficulties with scientific mediation turned to the area of the science, and consequently in the principles of understanding SL. Finally, we believe that the analysis of teachers' representations allows us to know the school needs within science education.
« Le Pays au bord de la mer ». La Poméranie entre la Baltique et le Saint-Empire
Authors: Chaline Olivier , Goetze Dorothée , Richard Nicolas
Published: October 2022

L’audacieux pari de Gustave II Adolphe, en débarquant à Usedom (1630), attira l’attention sur le vaste duché de Poméranie, dont l’intérêt pour l’histoire au xviie dépasse pourtant son importance comme théâtre de la guerre – les études historiques françaises manquent hélas sur cet espace. Cette introduction en présente le cadre géographique – des grands domaines céréaliers, un très long littoral dont les ports constituent les principales villes poméraniennes. Elle montre, après l’extinction de la dynastie des Griffon en 1637, l’évolution politique de cette terre baltique disputée, entre la Suède et le Saint-Empire, au contact du Brandebourg, de la Pologne et du Danemark. Elle s’interroge enfin sur les spécificités de cet espace, germain et slave, uni culturellement et religieusement.
Le duché de Poméranie et la dynastie des Griffon (Greifen) dans le premier tiers du XVII e siècle
Authors: Schleinert Dirk
Published: October 2022

En 1637 s’éteignit la dynastie des Griffon qui régnait jusqu’alors sur la Poméranie. L’absence d’héritier tenait tant à l’exclusion catégorique de toute succession féminine, qu’au fait que la dynastie était peu recherchée sur le marché matrimonial des princes, et ne s’alliait qu’à quelques rares autres maisons de l’Allemagne du Nord. En outre, tous les descendants mâles de la maison ducale de Poméranie étaient héritiers du duché de façon égale, ce qui se reflétait dans le gouvernement en commun ou dans les partages du territoire du duché. Cet article retrace l’origine, la mise en œuvre réelle de ces principes, et le développement de la Poméranie jusqu’à l’extinction de la dynastie des Griffon.
L’histoire littéraire et culturelle de la Poméranie au xvii e siècle
Authors: Schneikart Monika
Published: October 2022

En Poméranie se développa une culture littéraire qualifiée selon les canons de Martin Opitz (1624) de poésie occasionnelle. Cette production pouvait atteindre une très grande qualité, particulièrement dans le cas extraordinaire de la poétesse Sibylla Schwarz (1621-1638). Mieux connue, car mieux intégrée dans les milieux lettrés, est la génération post-humaniste des cercles savants de Rostock et de Stettin, auxquels d’ailleurs S. Schwartz appartenait ; ces literati étaient au courant de la vie intellectuelle de l’Europe du temps, et encouragés par la présence des cours ducales – ainsi, dans le premier tiers du xviie siècle, la production intellectuelle poméranienne eut une influence réelle à l’échelle de tout l’Empire.
Thomas Hobbes et la peur du « hobbisme » pendant la seconde moitié du xvii e siècle anglais
Authors: Untea Ionut
Published: October 2022

Les ingrédients nécessaires à l’émergence d’une école de pensée hobbiste circulaient parmi les sympathisants de la pensée de Hobbes tels que Scargill, Rochester, Stillingfleet, Osborne, B.E, ou encore chez certains jeunes gens ayant fait leurs armes dans les milieux universitaires ou les Inns of Court. Néanmoins, en dépit de leur jeunesse ou de leur charisme, ils n’en vinrent pas à être considérés comme des « gentilshommes » en capacité de perpétuer l’héritage hobbesien et de le développer en un système cohérent de pensée hobbiste. On peut y voir la conséquence des critiques et censures des contemporains qui, dans le sillage de Bramhall, avaient prononcé une sorte de « prophétie auto-réalisatrice » quant au danger imminent du hobbisme pour la stabilité sociale.
Britannicus , tragédie cornélienne ?
Authors: Alonge Tristan
Published: October 2022

L’article propose de mesurer le poids réel de l’influence de Corneille sur l’écriture racinienne lors de leur première rencontre : Racine ne s’est pas contenté de reprendre un thème romain, il a manipulé la source de Tacite pour aboutir à une structure très proche de celle de Cinna. Il n’a pourtant pas pu s’empêcher de perfectionner le palimpseste cornélien pour mieux coller aux enseignements d’Aristote, et de ne suivre qu’à moitié les suggestions du parti cornélien, ce qui explique peut-être l’échec de Britannicus sur la scène.

ARTICLE RETIRÉ : Exercice de l’autorité et autonomie des salariés : la subsidiarité en tension dans une savonnerie en quête de libération
Authors: Grevin Anouk , Préchoux Véronique
Published: October 2022

On assiste aujourd’hui à une remise en cause des modèles hiérarchiques traditionnels et de l’exercice de l’autorité qui leur est associé, la question de l’autonomie étant désormais au cœur des organisations. De nouveaux modèles d’organisation ont émergé, tels que les entreprises libérées, posant alors la question des conditions de leur fonctionnement et de la coordination du travail. Cet article cherche à comprendre si, dans le contexte de l’entreprise libérée, la subsidiarité peut constituer un principe de management à même d’organiser l’autonomie au travail. L’analyse du cas d’une savonnerie s’inscrivant dans la philosophie des entreprises libérées conduit à identifier certaines des difficultés qui émergent dans un contexte d’autonomie, et en particulier des difficultés de coordination et de priorisation, de prise de décision, et le sentiment d’un manque de soutien, liés à la difficulté du dirigeant à trouver comment exercer son autorité tout en développant l’autonomie des salariés. La mobilisation du principe de subsidiarité pour accompagner les entreprises libérées est analysée et discutée. Des limites sont identifiées pour permettre la prise de décision, mais aussi des conditions de son opérationnalisation, comme le droit à l’erreur et à l’incompétence et le soutien du dirigeant.

Psychologie empirique et empirisme métaphysique
Authors: Madelrieux Stéphane
Published: October 2022

Il existe une réception de la psychologie de William James en France avant et en-deçà de la célébrité qu’il acquit par son pragmatisme, et dont on peut retracer la diversité en dégageant les lignes de fracture intellectuelle de la fin du xix e  siècle. Bien que la réception bergsonienne l’ait finalement emporté, un écart surprenant apparaît entre le rapprochement devenu si familier entre James et Bergson et l’absence de confrontation réelle de Bergson vis-à-vis des principes de la psychologie de James. Ce hiatus culmine dans la proposition de Bergson de lire The Principles of Psychology comme un livre de philosophie, en faveur d’un programme général qu’on peut appeler « l’empirisme métaphysique », et qui détermine encore aujourd’hui nombre de lectures françaises de James.
Solitary wave solutions in time-fractional Korteweg-de Vries equations with power law kernel
Authors: Khan Khalid , Ali Amir , Irfan Muhammad , Khan Zareen A.
Published: October 2022

The non-linear time-fractional Korteweg-de Vries and modified Korteweg-de Vries equations are studied with Caputo's fractional derivative. The general higher-order solitary wave solutions are derived using a novel technique called the Aboodh transform decomposition method. To validate the obtained results, two examples of Caputo's fractional derivative with appropriate subsidiary conditions are illustrated. The accuracy and efficiency are confirmed by using numerical simulations and error analysis, where good agreements are obtained. The numerical analysis shows that, in comparison to the time-fractional Korteweg-de Vries solution, the solitary wave solution for the time-fractional modified Korteweg-de Vries equation is less stable against the oscillations. The variations in the temporal variable $ t $ enhance the strength of the wave solutions. Moreover, the wave perturbations taper off as $ t $ attains large values. The parameter $ \alpha $ signifies the fractional derivative influence on the wave dispersion and nonlinearity effects. This affects the amplitude as well as the spatial extension of the solitary waves. With a relatively small value of $ t $, the obtained solutions admit pulse-shaped solitons. Moreover, the wave's solutions suffer from oscillations when the temporal variable attains large values. This effect cannot be noticed in the soliton solutions obtained in the integer order systems.
Compactness and connectedness via the class of soft somewhat open sets
Authors: Al-shami Tareq M. , Mhemdi Abdelwaheb , Abu-Gdairi Radwan , El-Shafei Mohammed E.
Published: October 2022

This paper is devoted to study the concepts of compactness, Lindelöfness and connectedness via the class of soft somewhat open sets which represents one of the generalizations of soft open sets. Beside investigation the main properties of these concepts, it is demonstrated, with the help of examples, that some properties of their counterparts via soft open sets are invalid. Also, the relationships between these concepts and their counterparts defined in classical topology (which is studied herein under the name of parametric topology) are discussed in detail. Moreover, we provide the sufficient conditions that guarantee the equivalence between them. In this regard, it is proved that all introduced types of soft compact and Lindelöf spaces are transmitted to all parametric topologies without imposing any conditions, whereas the converse holds true under the conditions of a full soft topology and a finite (countable) set of parameters. These characterizations represent a unique behavior of these spaces compared to the other types defined by celebrated generalizations of soft open sets. Also, there is no relationship associating soft $ sw $-connectedness with its counterparts via parametric topologies. We successfully describe soft $ sw $-disconnectedness using soft open sets instead of soft $ sw $-open sets and consequently prove that the concepts of soft $ sw $-connected and soft hyperconnected spaces are identical. In conclusion, the obtained results show that the framework given in this manuscript enriches and generalizes the previous works, and has a good application prospect.
Equivalence of novel IH-implicit fixed point algorithms for a general class of contractive maps
Authors: Agwu Imo Kalu , Ishtiaq Umar , Saleem Naeem , Igbokwe Donatus Ikechi , Jarad Fahd
Published: October 2022

In this paper, a novel implicit IH-multistep fixed point algorithm and convergence result for a general class of contractive maps is introduced without any imposition of the "sum conditions" on the countably finite family of the iteration parameters. Furthermore, it is shown that the convergence of the proposed iteration scheme is equivalent to some other implicit IH-type iterative schemes (e.g., implicit IH-Noor, implicit IH-Ishikawa and implicit IH-Mann) for the same class of maps. Also, some numerical examples are given to illustrate that the equivalence is true. Our results complement, improve and unify several equivalent results recently announced in literature.
Vers une poétique post-numérique de l’illisibilité
Authors: Saemmer Alexandra
Published: October 2022

Les analyses et réflexions proposées dans cet article partent du constat d’une dépendance fatale des œuvres de littérature numérique vis-à-vis de leurs dispositifs techniques. L’instabilité et l’obsolescence notoires des œuvres résultent d’enjeux industriels qui les dépassent, les déterminent, les contraignent et parfois les mettent en péril. Pourtant, les prescriptions et contraintes ont également inspiré les arts littéraires numériques ces dernières années, rendant possibles des formes d’intermédialité impensables auparavant. La dépendance fatale vis-à-vis du dispositif technique a donné lieu à des détournements, infiltrations, tentatives d’infection virale et autres fuites en avant. Un certain nombre de ces œuvres qui s’écrivent à l’envers et à l’encontre des hardwares et softwares mobilisent une conception post-numérique de la contamination poétique, que j’essaierai de cerner et de contextualiser. Je m’appuierai dans mes analyses sur la sémiotique des écrits d’écran ainsi que sur une démarche de recherche et création critique en littérature numérique que je mène moi-même depuis plusieurs années avec des logiciels et sur des réseaux sociaux industriels.
Écritures amplifiées et défossilisations poétiques chez Emmanuelle Pireyre et Antoine Boute
Authors: Lahouste Corentin
Published: October 2022

À partir de deux cas spécifiques tirés de la production littéraire francophone des premières décennies du xxie siècle, ceux d’Antoine Boute et d’Emmanuelle Pireyre, sont abordées deux pratiques poétiques polymorphes qui, engagées dans une démarche transmédiatique et plurisémiotique de création, viennent (faire) déborder l’objet-livre traditionnel, en promouvant l’idée d’une littérature vive, d’une présenciation de l’acte poétique où ce dernier est avant tout appréhendé comme un « nœud de potentialités connectives » (Quintyn, 2019). Ainsi, que se passe-t-il lorsque la littérature se déporte d’un travail exclusif sur le langage et d’un unique ancrage sur la page ? Quand, inscrite dans une plasticité novatrice et relativement audacieuse, elle s’ouvre à des formes et pratiques étrangères à son champ et à ses limites assignées ? Quand, encore, l’idée communément partagée à son égard — c’est-à-dire des (beaux) mots agencés sur des pages reliées en un livre écrit par un·e auteur·e isolé·e — se voit chahutée, remise en question ?
Un écrivain dans les couloirs du Louvre
Authors: Martens David
Published: October 2022

Depuis le début des années 2000, nombre de musées et institutions (centres d’art, bibliothèques…) font régulièrement appel à des écrivain·e·s pour leur confier le commissariat d’expositions. Figure émergente au sein d’un écosystème des arts littéraires qui conduit de plus en plus d’auteurs et autrices à diversifier leurs modes d’intervention extra-livresques, l’apparition de l’écrivain·e-commissaire a été marquée, en France, par une série d’invitations lancées par le Louvre à des auteurs tels que Toni Morrison (2006), Umberto Eco (2009), Jean-Marie Gustave Le Clézio (2011), Jean-Philippe Toussaint (2012) et Philippe Djian (2014). Si la visée des institutions consiste à refaçonner leur image, un tel contexte d’interactions constitue également une opportunité permettant aux écrivain·es d’infléchir leur posture. Au sein de la programmation d’un musée qui a pour principale mission la transmission de connaissances sur l’art du passé davantage que la promotion de la création contemporaine, l’exposition Livre/Louvre, signée Jean-Philippe Toussaint, et accompagnée par l’ouvrage La Main et le regard, présente, au sein de celles que le Louvre a confiées à des écrivain·e·s, la singularité de se caractériser par un investissement résolu de la position d’artiste-commissaire. À la différence des autres écrivain·e·s conviés par le musée, l’auteur fait de sa proposition une œuvre à part entière, qui fait converger ses différents modes d’intervention.
Intégrer les technologies immersives à la scène contemporaine : quelles voies dramaturgiques ?
Authors: Valero Julie
Published: October 2022

Cette proposition s’intéresse aux difficultés dramaturgiques qu’engendre l’intégration des technologies immersives, et plus spécifiquement des casques de réalité virtuelle, à la forme théâtrale. Au-delà des complexités de mises en œuvre, il s’agit d’observer les narrations déployées dans ces dispositifs et de les interroger au regard de l’évolution des dramaturgies contemporaines : un dispositif expérientiel inédit, comme l’immersion virtuelle, est-il susceptible de faire émerger de nouvelles voies dramaturgiques ? La contribution propose de répondre à cette question à partir de l’analyse de trois projets récents : L.I.L.I Alix Wonderlands, du collectif Or NOrmes (2018), Les Falaises de V., de Laurent Bazin (2017) et Kant, d’Émilie Anna Maillet (2016). Ces trois projets mettent chacun en œuvre des stratégies dramaturgiques différentes : l’adaptation d’un texte non dramatique, l’écriture d’un scénario original et la narration transmédiatique. Nous observerons quelles possibilités ouvrent ces choix et quelles sont leurs limites. Au-delà, l’intégration d’une technologie popularisée par les industries culturelles et médiatiques, appelle à s’interroger sur ce que l’on attend aujourd’hui d’une « sortie culturelle ».
Identifying the Group Differences in the Impact of Haze on Residents' Low-Carbon Travel
Authors: Zhang Bin , Xu Zhen , Sun Liran
Published: October 2022

This paper matches the large-scale survey data and the corresponding historical weather data to explore how air pollution impacts on low-carbon travel choices. The K-means algorithm is employed to cluster the personal characteristics of residents into five groups according to their travel behavior. The authors take ordered Logit models to identify the group differences in the impact of haze on the five types of low-carbon travel choices, combining with the theory of responsibility attribution and protection motivation theory. The results show that haze has a significant impact on the two groups, namely young office workers and students. The other three groups will not consider the influence of haze when choosing travel vehicles, travel distance, and travel time. The quantity of personally owned automobiles also has a significant impact on the group differences in low carbon travel choices. It is indicated that low carbon travel policies should be considered in the group differences in the future, and efforts should be made from supply and demand sides to guide residents to choose low-carbon travel.
Ler, escrever e contar entre mulheres escravizadas
Authors: Peres Eliane
Published: October 2022

O objetivo principal deste artigo é identificar o domínio da leitura e da escrita entre mulheres escravizadas e analisar as circunstâncias desse aprendizado. Discute-se, primeiro, se havia ou não escolas para pessoas escravizadas; em seguida, expõem-se aspectos da formação das escravizadas, especialmente no que tange às habilidades domésticas; por fim, apresentam-se dados que revelam que o espaço da casa, seja dos senhores, seja de mulheres brancas, pobres ou em melhores condições sociais, pretas e pardas, forras ou livres, e algumas aulas e colégios privados femininos foram os lugares possíveis do aprendizado da leitura e da escrita para as escravizadas. Todos os dados da pesquisa foram coletados em jornais disponíveis na Hemeroteca Virtual da Biblioteca Nacional.
A educação de Populações Indígenas em Moçambique
Authors: Bavo Názia Anita Cardoso , Coelho Orquídea
Published: October 2022

A história da educação de populações indígenas em Moçambique foi marcada pela ação colonizadora de Portugal, desde o século XV até a sua independência nacional, em 1975. Com este trabalho, pretendemos apresentar e problematizar os principais marcos desse processo, no recorte temporal de 150 anos, compreendido entre 1834, em pleno Período Colonial, e 1984, no início da Era Pós-Independência. Este contributo para a compreensão da história da educação de nativos moçambicanos resulta de parte de um estudo doutoral desenvolvido no contexto das políticas educativas, realizado através de uma abordagem qualitativa com recurso ao método bibliográfico com base em fontes documentais. A interpretação dos dados assinala um conjunto de práticas colonizadoras de discriminação, marginalização e imposição de uma língua, bem como de clivagem e criação de um fosso entre as populações indígenas e os filhos dos colonizadores. A estas classes sociais estavam destinados regimes educativos diferenciados e penalizadores para os nativos, pois aqueles visavam a reproduzir e a perpetuar o sistema de dominação colonial, sobretudo por meio da sua orientação para a produção de mão de obra. Constatamos também que algumas destas marcas do passado se mantiveram na Era Pós-Independência como herança de uma certa cultura educacional com a qual o povo moçambicano se debate para alcançar os seus desígnios.
Capas da “Cacique”
Authors: Nunes Marilia Forgearini
Published: October 2022

O artigo analisa capas de uma revista brasileira publicada nos anos 1950. Dentre 43 capas da Cacique assinadas pela mesma artista, foram selecionadas 18 para análise. A semiótica discursiva é a base teórico-metodológica, associada a argumentos da sociologia da infância, da técnica da ilustração e da história do impresso. Questiona-se sobre como os temas criança, brincar e brincadeira revelam efeitos de sentido e discursos relacionados ao contexto histórico da publicação. A análise demonstra que as capas transparecem uma infância restrita, com pouco espaço para uma cultura da infância, para brincar e agir criativamente. Reitera-se a importância dos impressos tanto sob a perspectiva da imanência de sentidos no objeto quanto sob a ótica dos efeitos de sentido históricos, sociais e culturais (re)construídos.
Verification of the Physical and Mechanical Properties of the Heavyweight Concrete Used in the Shielding Construction of Reactor Casing at the Nuclear Power Plant
Authors: Dragomirová Janette , Palou Martin
Published: October 2022

The present paper deals with the determination of the mechanical and physical properties of the heavyweight concrete formulation used in the shielding construction of the reactor casing power plant. The recipe includes the use of baryte and cast-iron crumbs as fillers for the preparation of heavyweight concrete. The binder paste was obtained using CEM I 42.5 R with w/c ratio = 0.44 and a lignosulfonate-based plasticizer prepared according to the used Ralentol plasticizer's standard requirements, which is currently no more produced. The result of the concrete slump according to the S -cone was S1 (1 cm slump). The bulk density of fresh and hardened concrete was over 4000 kg m-3. The compressive strength at 28 days exceeds 80 N mm-2 and the flexural strength is 4 N mm-2. The modulus of elasticity is 40 GN m-2. The shrinkage of concrete is 0.52 ‰. The weight loss due to shrinkage rises to almost 1.3 %. The thermal properties of the heavyweight concrete are as follows: the thermal conductivity λ is 2.2 W m-1 K-1; the thermal resistance R for thickness d = 1 m is 0.44 m2 K W-1; volume heat capacity cρ rises to almost 2 J m-3 K-1 and thermal diffusivity a 10-6 drops to 1,15 m2 s-1.
Electrical Properties of Bi0.5Na0.5TiO3/ PVDF(25/75) Composite
Authors: Kumar Archana , Kumar Amit , Pratap Suraj , Aryan Harsh , Prasad Kamal
Published: October 2022

The mechanical impact-based energy harvesting behavior of a 0-3 Bi0.5Na0.5TiO3/PVDF(25/75) composite prepared using the melt-mixing method have been demonstrated. X-ray diffraction analyses revealed the formation of a composite sample, while AFM image analyses revealed that BNT-particle sizes ranged between 0.6 and 1.4 μm and were evenly distributed throughout the polymer matrix, and surface roughness was found to be between 0.2 and 1.8 μm. With increasing impact height (applied mechanical energy), a remarkable increase in generated electric voltage and energy was observed. As a result, the present composite is a better lead-free alternative for piezo-sensing/detection and energy harvesting applications.

Authors: Xing Tao , Vernier Nicolas , Zhang Xue Ying , zhang You Guang , Zhao Wei Sheng
Published: October 2022

We present here a method for measuring the temporal Bakehausen scaling exponent in a two-dimensional thin film. The scaling exponent with long-range interaction is observed to be consistent with theoretical and experimental results. In addition, we demonstrate the characteristic exponent with short-range interaction. Our method contributes to the understanding of DW dynamics and helps to optimize spintronic devices.
