Electromigration-induced formation of percolating adsorbate islands during condensation from the gaseous phase: a computational study
Authors: Dvornichenko Alina V , Kharchenko Vasyl O , Kharchenko Dmitrii O
Published: July 2021

We provide a computational study of a change in the morphology of a growing thin film during condensation caused by electromigration effects. It will be shown, that separated circular adsorbate islands, realized in an isotropic system, become elongated in the direction of the applied electrical field. We discuss the dependence of the critical value of the strength of the applied electrical field, responsible for the formation of percolating adsorbate islands, on main control parameters. This study provides insight into details of electromigration effects during the self-organization of adatoms into percolating adsorbate islands during condensation from the gaseous phase. We will show that the elongated morphology of adsorbate islands remains stable if the electric field is turned off.

A rendőri hivatás története és elemei
Authors: Nándori Nikoletta Petra
Published: July 2021

The study shortly examines the relevant periods in the history of Hungary in terms of the police profession. My goal is to explore the elements of the profession that can be read from the Hungarian law enforcement literature of the 19th and 20th century. In addition to the social changes that took place during the era, it was of paramount importance that the state armed bodies, including the police, perform their duties in accordance with well-established professional expectations. The police served their social function in the state organization as a branch of the administrative authority. The study describes the nature of the police profession, starting from the examination of the elements. The examination includes the exploration of the social role of the police and the moral justification of this role, as well as the abilities and virtues expected of the police force, which, among other things, facilitate the integration of the police force and thus its more efficient performance. However, they form an important contact between law enforcement and society.

Variations in the Pickup Ion Density Structure in Response to the Growth of the Kelvin–Helmholtz Instability along the Heliopause
Authors: Tsubouchi Ken
Published: July 2021

Features of the response of pickup ions (PUIs) to the Kelvin–Helmholtz instability (KHI) on the heliopause (HP) are examined by means of two-dimensional hybrid simulations. We assume the supersonic neutral solar wind as the source of PUIs gyrating about the magnetic field in the outer heliosheath. These PUIs become energetic neutral atoms (ENAs) via charge exchange with interstellar hydrogen, and a portion of these ENAs are detected by spacecraft such as the Interstellar Boundary Explorer (IBEX). To evaluate the possibility of identifying the KHI on the HP from ENA observations, we assume that an imprint of the KHI may be displayed in spatial and temporal variations in the observed ENA profile. As an alternative to ENA, the column density of PUIs integrated across the HP is calculated. The KH-inducing vortex forces not only background protons but also PUIs to roll up deep in the inner heliosheath. The KH vortex also results in the emission of magnetosonic pulses that sweep PUIs in the outer heliosheath and lead to their local confinement. These effects elongate the PUIs’ spatial distribution in the direction normal to the HP. The appearance of the local confined structure in the PUIs’ column density is consequently confirmed, and this feature can be confirmed as the KHI evolution. Although the simulation cannot be quantitatively compared with the observations currently available because its resolution is too low, we expect that the derived properties will be useful for diagnosing the nature of HP fluctuation in future missions.

Formaliser l’empire pour favoriser le commerce. Les stratégies institutionnelles de la pénétration européenne du marché mexicain (1821-1867)
Authors: Bartolomei Arnaud
Published: July 2021

Bio-bibliographie : Maître de conférences en histoire moderne et contemporaine à l’Université Côte d’Azur et auteur d’un ouvrage sur la colonie marchande française de Cadix ( Les marchands français de Cadix , 2017), Arnaud Bartolomei est actuellement membre de la Casa de Velázquez où il travaille sur le commerce dans l’Atlantique hispanique à la veille et au lendemain des indépendances américaines (1750-1850).   Le présent article propose une contribution à la polémique sur « l’impérialisme du libre-échange », fondée sur des archives consulaires largement inédites. Il s’agit de déterminer si l’expansion commerciale européenne du xix e siècle a été fondée, ou non, sur la mobilisation et l’instrumentalisation des institutions publiques des pays européens. La question est abordée ici à partir de l’exemple du Mexique qui fut le théâtre de deux expéditions militaires européennes, française en 1838-1839 et franco-hispano-britannique en 1861-1867. Les conclusions dégagées valident la théorie de « l’impérialisme du libre-échange » formulée par Gallagher et Robinson en 1953 sur deux points : les interventions militaires européennes étaient généralement souhaitées et sollicitées par les milieux d’affaires et leurs objectifs étaient clairement de favoriser les intérêts commerciaux des pays qui en étaient à l’origine. Les résultats ne permettent pas en revanche d’affirmer que ces politiques impérialistes jouèrent un rôle décisif dans l’expansion commerciale européenne.
L’immigration dans les campagnes françaises : des effectifs limités mais des origines qui ne cessent de se diversifier
Authors: Fromentin Julie , Pistre Pierre
Published: July 2021

En France métropolitaine, les habitants immigrés ou étrangers représentent une faible part (respectivement 4,3 % et 2,5 %) mais constante de la population des campagnes depuis les années 1970. S’ils résident principalement dans les régions frontalières, dans l’Ouest de la France ou à proximité des grandes et moyennes agglomérations, leur répartition spatiale est de plus en plus homogène et concerne l’ensemble des campagnes. Les immigrés d’Europe du Sud, d’Europe de l’Ouest et du Nord, et du Maghreb, sont les plus nombreux ; ils se différencient notamment par la taille des ménages dans lesquels ils vivent, plus petits pour les Européens. Mais d’autres groupes ont vu leurs effectifs augmenter et participent à la lente croissance des effectifs des immigrés et des étrangers, et à une diversification de leurs origines géographiques depuis au moins les années 1990.

Droit et liberté dans les sociétés sans État : une relecture de Pierre Clastres à la lumière d’une approche microscopique du droit
Authors: de Brogniez Maxime
Published: July 2021

La théorie microscopique du droit élaborée par Lucien François lève l’incurable ambivalence sémantique du mot « droit » en repensant le phénomène juridique à partir de sa manifestation minimale, le jurème . Les outils fournis par Lucien François permettent de porter un regard neuf sur les sociétés sans État, sociétés que Pierre Clastres qualifie de sociétés contre l’État. À partir des travaux de Pierre Clastres, nous montrerons que ces sociétés, bien que sans État, ne sont pas a-juridiques pour autant. Il existe des rapports juridiques qui prennent une forme très particulière, celle du cercle d’exigence mutuelle . Cette figure, ainsi que celle du nimbe – également thématisée par Lucien François –, permettront de questionner la notion de liberté dans ces sociétés. Si celle-ci peut au premier abord paraître radicalement opposée à nos conceptions, la réalité est sans doute moins binaire.
Économie de l’empathie dans un bureau d’immigration polonais : mise en jeu des sentiments, reconnaissance des liens familiaux et droit au séjour
Authors: Skowronska Kaja
Published: July 2021

Le lien familial constitue un des motifs possibles d’obtention d’un statut administratif pour les étrangers, en Pologne comme dans d’autres pays. Au-delà des règles formelles, la famille est aussi un domaine investi d’une importante charge émotionnelle. Elle est le lieu de l’intime, des sentiments et des attachements. Les agents de l’État qui travaillent à l’intersection des questions de l’immigration et de la famille portent leur regard sur la sphère de l’intime, tout en mobilisant des conceptions de l’altérité et de la similitude. L’émotion peut devenir alors un instrument de catégorisation des migrants. Évaluer le bien-fondé d’une demande de régularisation ou de naturalisation basée sur les liens familiaux revient à évaluer également la véracité des sentiments exprimés par ceux qui la déposent. Dans les street-level bureaucracies chargées de la mise en œuvre de politiques migratoires, le pouvoir discrétionnaire laissé aux agents s’exprime souvent par des gestes en apparence anodins, motivés par l’empathie ressentie par les agents et par leur capacité à lire les sentiments de leur public. Dans cet article, nous nous interrogeons sur les usages de l’émotion dans une agence administrative chargée de la gestion de l’immigration en Pologne, afin d’éclairer la manière dont cette dimension émotionnelle participe à la sélection des migrants perçus comme légitimes.

Des souverainetés. Débâcle à la frontière, autour de la pensée de Giorgio Agamben
Authors: Van Kerckhove Antoine
Published: July 2021

En établissant une corrélation fondamentale entre le pouvoir souverain et le ban qui contient le camp, Giorgio Agamben conceptualise un modèle de souveraineté qui allie la biopolitique foucaldienne avec la faculté schmittienne de suspendre le droit. Ce modèle est néanmoins relativisé empiriquement et conceptuellement, par Michel Agier et Martin Deleixhe notamment. Cet essai se proposera de concilier ces critiques avec le modèle d’Agamben, en nuançant sa thèse principale qui pose le camp comme paradigme biopolitique des États occidentaux contemporains. Cela nous portera à réélaborer cette thèse en mobilisant la notion de frontière. Nous avancerons ainsi que la frontière, au sein de laquelle se crée le camp, constitue le paradigme en question. Le camp sera dès lors appréhendé comme le paroxysme du « faire-frontière » à l’œuvre dans nos États actuels.

Le « doux secret de Ta grâce »
Authors: Robert Sylvie
Published: July 2021

L’approche rahnérienne de la vie spirituelle « dans la grâce » présente une véritable théologie de l’expérience spirituelle qui prend en charge les questions de fond que rencontrent toute vie et toute théologie spirituelle ; tout en étant théologique, elle respecte le caractère propre de l’expérience spirituelle en sa différence d’avec la théologie systématique. La fluidité de la grâce, sa capacité à articuler transcendance et immanence mais aussi initiative de Dieu et liberté humaine, le rapport qu’elle entretient avec les affirmations dogmatiques de la foi chrétienne sont des atouts précieux pour une théologie spirituelle fondamentale dans un contexte où le spirituel est sorti de la seule sphère chrétienne.

Adaptive controllability of microscopic chaos generated in chemical reactor system using anti-synchronization strategy
Authors: Khan Taqseer , Chaudhary Harindri
Published: July 2021

In this manuscript, we design a methodology to investigate the anti-synchronization scheme in chaotic chemical reactor system using adaptive control method (ACM). Initially, an ACM has been proposed and analysed systematically for controlling the microscopic chaos found in the discussed system which is essentially described by employing Lyapunov stability theory (LST). The required asymptotic stability criterion of the state variables of the discussed system having unknown parameters is derived by designing appropriate control functions and parameter updating laws. In addition, numerical simulation results in MATLAB software are performed to illustrate the effective presentation of the considered strategy. Simulations outcomes correspond that the primal aim of chaos control in the given system have been attained computationally.
A generalized approach to indeterminacy in linear rational expectations models
Authors: Bianchi Francesco , Nicolò Giovanni
Published: July 2021

We propose a novel approach to deal with the problem of indeterminacy in linear rational expectations models. The method consists of augmenting the original state space with a set of auxiliary exogenous equations to provide the adequate number of explosive roots in presence of indeterminacy. The solution in this expanded state space, if it exists, is always determinate, and is identical to the indeterminate solution of the original model. The proposed approach accommodates determinacy and any degree of indeterminacy, and it can be implemented even when the boundaries of the determinacy region are unknown. Thus, the researcher can estimate the model using standard software packages without restricting the estimates to the determinacy region. We combine our solution method with a novel hybrid Metropolis–Hastings algorithm to estimate the New–Keynesian model with rational bubbles by Galí (2021) over the period 1982:Q4–2007:Q3. We find that the data support the presence of two degrees of indeterminacy, implying that the central bank was not reacting strongly enough to the bubble component.

An Empirical Investigation of the Mentor-Mentee Relationship Among Female Architects and Female Architectural Students
Authors: Afolabi Adedeji Olushola , Akinola Adedotun
Published: July 2021

Women are highly underrepresented in the construction industry. In line with the sustainable development goals (SDGs) of the United Nations of gender quality and reducing inequalities, there is a need to think of innovative and sustainable frameworks to increase women's quota in the construction trade, especially in architecture. The study investigated the mentor-mentee relationship between female Architects and female Architectural students. The study utilized a research survey approach using a questionnaire data instrument. Using a purposive sampling technique, 84 research participants, consisting of female Architects and female Architecture students, participated in this study. The data collected are presented using bar charts, mean scores, principal component analysis (PCA), and categorical regression (CAT-REG). The study identified characteristics associated with good Mentors and good Mentees in the design profession. Mentees identified the main features that make a good mentor as the ability to teach, listen attentively, and communicate effectively. On the other hand, Mentors identified the qualities of a good mentee who communicates, is focused and demonstrates intelligence. The study showed that the significant negative experiences in a mentor-mentee relationship include a clash of personalities between the mentors and mentees, stealing credit for work done by both parties, and unrealistic expectations. Furthermore, these negative experiences result from poor attitude, wrong emotions, and loss of motivation. In conclusion, the study showed that proper implementation of Women mentoring programs among design professionals could lead to potential outcomes such as improved productivity, empowerment of inexperienced personnel, attracting likely female students, retaining women professionals, higher salaries, higher job satisfaction, and an increase in role models/mentors.

The present study is aimed at analyzing the impact of digital sto-rytelling on English as a Foreign Language (EFL) pre-service teachers’ writing skills. The participants were 101 students, who were enrolled in four distance courses of the English Major at a private university in Ecuador. Their ages ranged between 19 and 22 years old. They were divided into one control (49) and one experimental (52) group since this study used a quasi-experimental approach combined with a mixed-method design. The instruments included a pre-question-naire, a pre-test, a post-questionnaire, and a post-test. The main findings show that there was a significant improvement in students’ writing skills, particularly in aspects related to grammar and vocabulary. In addition, digital storytelling us-ing Storybird was perceived as a useful strategy to develop the participants’ EFL writing skills since they were more engaged in activities that allowed them to demonstrate their knowledge when designing narrative projects.
An Automatic Optimal Course Recommendation Method for Online Math Education Platforms Based on Bayesian Model
Authors: Fan Yongyan , Zhang Jing , Zu Dingli , Zhang Hongyu
Published: July 2021

Online education platforms inject new vitality into the field of education, and greatly improves the accessibility to high-quality education resources. However, the current online education platforms do not support independent course selection based on personal preferences. To solve this problem, this paper designs an automatic recommendation method of optimal courses for online math education platforms based on Bayesian model. The results show that the Bayesian model can simulate the causal relationship between real-world affairs by building a graphic model based on the graph theory and the probability theory; the model can effectively merge priori and posteriori information, and encode the causality between knowledge points; the model clearly outshines user-based collaborative filtering model, term-based collaborative filtering model, and SlopeOne model, and achieves a stable accuracy rate in automatic recommendation of courses. The research provides an empirical evidence to the improvement and innovation of professional online math course platforms.
ODK-X: From A Classic Process To A Smart Data Collection Process
Authors: Tikito Iman , Souissi Nissrine
Published: July 2021

Data collection is one of the first and main phases of the data life cycle. It enables improvements to be made across all phases of the data lifecycle. In this sense, we have proposed a data collection process qualified as Smart. For our smart data collection process, we have adopted the principles of the smart data approach allowing less data to be transmitted to the analysis and storage processes, while maintaining better data quality. In addition, we also used Edge computing since it provides services with faster response and better quality, compared to cloud computing. To experiment this process on mobile data, we propose to extend a mobile data collection software solution and adopt one of the key data collection methods. In this paper, we tested our smart data collection process via the ODK-X software suite and were able to identify the added value of our process compared to the one used by default during collection.

The development of mobile technology has an important role to play in achieving 21st-century skills. Collaborative skills and problem-solving are seen as fundamental skills for achieving 21st-century skills as a whole. This study aims to develop collaborative problem-solving based on mobile multimedia (CPMM) to achieve student collaborative and problem-solving skills. Multimedia development life cycle (MDLC) is used as a research method to develop CPMM. The CPMM was developed by involving 100 students at the Universitas Muhammadiyah Surabaya, Indonesia. The CPMM development result consisted of three main features. The first feature was the homepage which was used to show student profiles and progress in the course. The second feature was collaborative to become a forum for students to discuss and interact in multi-way mobile ways to solve problems. The third feature was evaluation as tasks from a lecturer to individual students to solve problems. In addition, the study results showed that CPMM was valid and effective for improving students' collaborative and problem-solving skills. This study recommends that CPMM can be used as an essential study and the basis for lecturers and practitioners to develop 21st-century student skills as a whole (not only collaborative and problem-solving skills) to produce graduates who are ready to face the revolutionary era 4.0.

The research aims to know the impact of science, technology, engineering, and mathematics education on both creative thinking and mathematical achievement. To achieve it, the two researchers followed the quasi-experimental approach with an experimental design for two groups, one experimental and the other a control. The research sample consisted of (32) female students from the fourth scientific grade in Al-Intisar Preparatory School for Girls / Al-Rasafa, First Directorate. The sample was chosen intentionally and was divided into two groups: a control group studying by the traditional method, their number (16), and an experimental group that applied the STEM approach, their number also (16). There was parity between the two research groups in the variables (chronological age, previous achievement in mathematics, innovative thinking). The research tools consist of testing innovative thinking skills (fluency, flexibility, originality, relationships) and achievement tests. The research experiment was applied before and after. To test the validity of the hypotheses, data were collected and then statistically analyzed using appropriate statistical methods. The results of the research found that there were statistically significant differences in both the tests of innovative thinking and mathematical achievement in favor of the experimental group that studied according to the STEM approach, and in light of the results, the researchers recommended several recommendations and suggestions.
Deux gestes pour une grande danse
Authors: Beaudet Jean-Michel
Published: July 2021

Ce bref ensemble présente deux gestes — l’un de femme, l’autre d’homme — associés à une grande cérémonie dansée chez les Wayãpi du haut Oyapock. On y voit d’abord que certains gestes peuvent être sexués : ici, de même que la « répartition sexuelle » des tâches est très marquée, la répartition sexuelle des gestes est bien perceptible, et s’apprend tôt. Mais surtout, nous tenterons de détailler les aspects plastiques de ces gestes en laissant percevoir les distinctions et les croisements entre geste quotidien et geste d’appareil au sein d’un même événement, l’ensemble de la cérémonie.

Cet article s’intéresse à une expérience spatiale, à la nature, à la forme et aux enjeux d’un « dispositif chorégraphique », c’est-à-dire à la manière dont les danseurs et danseuses s’organisent et se déplacent pendant la performance. Dans la morenada, une danse dévotionnelle exécutée lors des fêtes patronales boliviennes, ce dispositif réunit plusieurs centaines d’hommes et de femmes qui au premier abord paraissent tous danser de manière synchronisée, formant des blocs rigoureusement construits. Pourtant, une fine attention portée aux déplacements des femmes pendant la danse montre qu’elles engagent en réalité des forces de nature contraire : la volonté impérative de construire un collectif soudé mais aussi celle, à l’inverse, de se démarquer de l’ensemble. Tantôt l’effort des danseuses est porté sur la volonté de faire du semblable, tantôt celles-ci réalisent des actions perturbatrices qui mettent à l’épreuve toute l’organisation générale. Comment comprendre au sein d’une même unité spatio-temporelle la coexistence de ces deux dynamiques ? Quelles règles sociales et quelles relations féminines sont ici à l’épreuve à travers la danse et ses (en)jeux spatiaux ?

Shaft failures often occur, even in the shafts of centrifugal pumps. This study aims to determine the cause of shaft fracture through experimental and numerical study. The fracture surface was observed using Scanning Electron Microscopy (SEM) to identify the initial crack. The chemical composition test results show that the material used was in accordance with the AISI 420 standard, which is necessary to make Finite Element Analysis (FEA) modelling. Shear stress, strain and stress intensity factors were analysed around the fillet using FEA. The results show that the value of maximum stress intensity factor, KI, occurs in the multilevel shaft fillets that experienced initial cracks due to torsional loads. The shear stress value, obtained from the FEA, was higher than the shear stress value of the material. The KI value, also derived from the FEA, was higher than the KICvalue of the material.

Dissimilar weld-metal joints in aluminum alloys 5083 and 6061-T6 are often found in aircraft, railroad structures, ships, bridges, oil platforms, and building structures. However, welding of dissimilar metals is relatively more difficult due to the different metallurgy and thermophysical properties of the two alloys. The purpose of this study is to evaluate the physical-mechanical properties of the Tungsten Arc Welding (GTAW) process through numerical simulations of different welded joints between the 5083 and 6061-T6 aluminum alloys. The GTAW welding simulation process is carried out by 300 x 100 x 3 mm plate butt joints along 300 mm. GTAW weld metal is prepared for tensile test samples and metal alloy composition, the test is observed in the base metal and welded area. The results of the chemical composition test of the weld metal obtained that the composition is close to Al 5083 base metal so that the mechanical properties of the weld metal tend to be identical with Al 5083 alloy. The results of numerical simulation on the mechanical properties of GTAW weld metal at temperature conditions of 25 to 700 °C obtained several things, including 1) the range of thermal conductivity decreased from 174.393 to 86.424 W/mK. 2) The density increased from 2,348 to 2,663 gr/cm3. 3), the young modulus appears to decrease from 68,667 to 0 GPa. 4) the shear modulus decreases from 25,724 to 0 GPa. 5) the type of heat increases from 0.904 to 17,306 J/gK, and 6) the Poisson ratio increased from 0.335 to 0.5.

The article analyses the effect of temperature distribution at different points of the irradiation zone on the nature of leakage of structural-phase transformations. The results of the X-structural analysis are given, which shows the presence of martensite and residual austenite in the treatment zone. The peculiarities of structural-phase transformations during laser heating are studied and their effect on strain value during laser shaping is determined. The results of experimental studies are given, according to which, if the mechanisms for forming the temperature gradient and polymorphic transformations (for 65G steel) operate in parallel, the amount of deformation is one third of the sample for which only the temperature gradient mechanism works (12Х18N10Т steel).

In a number of water use schemes (water and wastewater treatment), physicochemical treatment methods, in particular adsorption, have been successfully used. However, widespread adoption of these methods is hindered by the high cost of sorbents. One of the promising solutions to these problem of sorption treatment is the use of biochar. Due to its high specific surface area, well-developed porous structure, and surface functionality, biochar has been used as inexpensive adsorbent. The purpose of the laboratory experiments is to determine the sorption properties of biochar obtained from pine – sorption capacity, sorption rate, and purification effect – while removing organic contaminants from real paper mill wastewater. The sorption properties of biochar were studied under static and dynamic conditions, varying the size of the fractions, and processing time. The sorption characteristics of biochar of all the studied fractions were established and it was shown that the most effective sorbent in removing organic contaminants is the 1-biochar’s fraction of (sorption capacity of 11.9 mg of COD per of sorbent). The data obtained enable theoretically substantiate the presence of certain functional groups on the surface of the researched biochar, as well as to develop technological regimes for the treatment of natural and waste waters of a certain composition with its help.
