#AffaireBenalla : déconstruction d’une polémique sur le rôle de la communauté Twitter « russophile » dans le débat politique français
Authors: Gérard Colin , Marotte Guilhem 
Published: June 2020

Au mois d’août 2018, la Russie est soupçonnée d’avoir amplifié la controverse provoquée par l’affaire Benalla via l’activité générée par ses médias internationaux RT et Sputnik sur Twitter. Cette polémique, provoquée par la récupération politique et médiatique d’une étude publiée par l’ONG EU DisinfoLab, illustre l’émergence d’un paradigme sur la capacité de la Russie à manipuler l’opinion publique d’États tiers grâce à la stratégie d’influence qu’elle déploie sur les réseaux sociaux depuis le début de la décennie. L’article propose de déconstruire cette polémique grâce à une approche critique de données récoltées sur Twitter.
Souveraineté numérique et autonomie stratégique en Europe : du concept aux réalités géopolitiques
Authors: Danet Didier , Desforges Alix 
Published: June 2020

Conceptuellement distinctes mais très étroitement imbriquées les deux notions de souveraineté numérique et d’autonomie stratégique numérique renvoient à la volonté des acteurs politiques et économiques européens de conserver la maîtrise de leur destin dans l’espace numérique. Il s’agit pour les États membres et pour l’Union européenne de se doter d’une capacité autonome d’appréciation, de décision et d’action afin d’exercer leur souveraineté. Cette question suscite un intérêt croissant en Europe et l’article se propose d’en examiner tout à la fois le sens géopolitique et les conditions de réalisation économique et industrielle.
The Pat Hobby Stories : F. Scott Fitzgerald ou « la vocation de l’échec »
Authors: Gay Marie-Agnès 
Published: June 2020

Les héros fitzgeraldiens cheminent le plus souvent de la réussite à l’échec, en écho à l’auteur dont la vie personnelle et professionnelle suivit cette trajectoire. Pat Hobby, héros d’un cycle de dix-sept nouvelles écrites par Fitzgerald à Hollywood quelques mois avant sa mort, ne fait pas exception. Cet article lit dans un premier temps les nouvelles à l’aune de ce constat, avant de voir dans ces textes l’expression d’un double échec plus fondamental : échec ontologique à être, et échec littéraire à dire.
Failing Private Till: John Edgar Wideman’s Writing to Save a Life: The Louis Till File
Authors: Valadié Flora 
Published: June 2020

Écrire pour sauver une vie : le dossier Louis Till constitue pour John Edgar Wideman l’ultime tentative de regarder une photo qui le hante depuis des décennies : celle du cadavre d’Emmett Till, jeune garçon noir de Chicago qui fut lynché dans le Mississippi en 1955 pour avoir osé aborder une femme blanche. Wideman plonge dans l’archive du père d’Emmett, Louis, qui fut soldat en Italie pendant la deuxième guerre mondiale et fut condamné à mort par une justice militaire expéditive l’accusant de viol et de meurtre. Les tortionnaires d’Emmett furent acquittés, justifiés par les minutes du procès du père, versées au dossier du fils pour accabler ce dernier. Wideman rouvre le cas Louis Till et se penche sur ses probables mensonges, dans une enquête historique, fictive, et autobiographique. Pourtant l’écrivain reconduit, tout au long de ce mémoire, le constat de l’échec de ses mots à saisir cette vie fantôme et ces spectres raciaux de l’Amérique, de sorte que l’échec de la représentation met finalement en déroute toute ambition d’enquête historique ou de restitution, révélant la faille éthique et méthodologique de l’enquête officielle sur le cas Louis Till. L’échec y est politique en cela qu’il décèle la nature téléologique, et par conséquent fictive et idéologique, de l’enquête. Pourtant, cet échec du récit à produire un contre-récit est la trame même de cette vie et de cette Histoire que le texte figure, poétiquement.
Stéréotypes de genre et construction visuelle de l’artiste au XIX e siècle
Authors: Delille Damien 
Published: June 2020

Les théories féministes appliquées aux études visuelles ont permis d’interroger le rôle des stéréotypes de genre, conçus comme catégorie de visualisation et de contrôle du corps des femmes à l’heure de la reproductibilité technique. C’est en suivant son évolution tout au long du xix e siècle, à travers la caricature et l’illustration de presse, qu’il s’agit d’interpréter l’assignation des femmes aux activités domestiques, la misogynie subie par celles qui s’en écartent, et la création de types et de contretypes dans les espaces de l’art. Face à la normalisation des comportements et des affects, les stéréotypes du peintre de bohème, de la femme artiste bas-bleu et de l’esthète homosexuel représentent autant de figures artistiques repoussantes et fascinantes à interroger. L’espace de vision devient un champ somatique de stigmatisation et de contestation politique des normes, qui façonne en retour les regards portés par la modernité.
Pour une archéologie du concept de « médium » à l’âge du romantisme. Turner, Hazlitt, Ruskin, Goethe
Authors: Somaini Antonio 
Published: June 2020

Dans un texte intitulé « On Imitation » (1817), le critique anglais William Hazlitt écrit que les tableaux de Turner « ne représentent pas tant les objets de la nature que le médium à travers lequel ils sont vus ». Cette citation devient le point de départ pour analyser la présence, dans le contexte du romantisme anglais et allemand, d’une des lignes généalogiques qui traversent l’histoire du concept de « médium » : une signification selon laquelle le médium n’est ni un intermédiaire entre le monde des vivants et celui des morts, ni un ensemble de supports et de techniques définissant la spécificité d’une création artistique, ni un « prolongement de l’homme » (McLuhan), ni même une série de techniques et d’opérations capables de stocker ou transmettre des informations (Kittler). Le médium est ici, plutôt, l’environnement, le milieu ou l’ Umwelt dans lequel se déroule l’expérience sensorielle : une idée qui puise ses racines dans les concepts aristotéliciens de diaphanes et métaxu et dont on peut suivre la présence jusqu’à une théorie contemporaine des médias.
Notre-Dame, mère de notre patrimoine commun
Authors: Personnaz Charles , Tardivel Émilie 
Published: June 2020

Notre-Dame de Paris occupe une place particulière dans le patrimoine français, car elle est à la fois un élément fondamental de ce patrimoine et le monument à partir duquel la notion de monument historique s’est forgée. La cathédrale se situe au point de convergence de multiples dimensions historiques, artistiques, techniques, hospitalières, liturgiques, spirituelles. Toutes ces dimensions doivent être prises en compte dans le projet de restauration, en y incluant l’environnement de l’édifice et notamment l’Hôtel-Dieu. L’incendie du 15 avril 2019 devrait être le point de départ d’une nouvelle réflexion sur le rôle de l’État dans la préservation du patrimoine commun.
Réfléchir sur une Église « en transformations ». Un état des lieux en ecclésiologie
Authors: Chiron Jean-François 
Published: June 2020

Présenter un « état des lieux » d’une Église « en transformations » oblige à partir du contexte actuel, aussi bien social qu’ecclésial. On doit notamment prendre en compte les options réformatrices de l’actuel pontificat et les enjeux ecclésiologiques qu’ils impliquent. C’est à ces conditions qu’il sera possible de considérer les questions de fond : synodalité, ministères, rôle des femmes… La qualification de l’Église comme « sacrement du Royaume » est proposée, comme la plus apte à dire quelque chose de la « raison d’être » de l’Église in mundo huius temporis .
The Ivory Saltcellars: A contribution to the history of Islamic expansion in Greater Senegambia during the 16th and 17th centuries
Authors: Mota Thiago H. 
Published: June 2020

This article aims to discuss Islamic expansion in West Africa during the 16th and 17th centuries along with carved ivory production. The analysis concerns the Greater Senegambia, a region comprised of the Senegal River basin in the north, the Futa Jalon plateau in the east, and northern Sierra Leone in the south. The study is based on European written sources, African oral traditions, and African carved ivories owned by the Ethnologisches Museum in Berlin, Germany. Its main hypothesis is that the 16th and 17th centuries comprised the moment of Islamic social expansion, before Islam turned into a major political force in Senegambia during the 18th and 19th centuries. Therefore, this paper’s goal is to present a conjoint understanding of the ivory pieces and early Islamic expansion, by focusing on the images carved in ivory saltcellars that are associated with Western African Islamic written culture.

Authors: Winkelmann Zachary , Eberman Lindsey E. 
Published: June 2020

ContextTelemedicine is the practice of providing diagnostic consultations and therapeutic interventions to patients at a distance using some form of technology. Typically, health care students do not have the opportunity to practice telemedicine.ObjectiveTo investigate athletic training students' ability to transfer telemedicine skills confidently and accurately in a standardized patient (SP) encounter.DesignSingle cohort.SettingSimulation center.Patients or Other ParticipantsFifty-five second-year athletic training students (age = 25 ± 3 years) from 6 professional master's athletic training programs volunteered for the study after a 1-week online learning experience about telemedicine.Intervention(s)We scheduled individual SP encounters that were completed at a distance using telepresence robots.Main Outcome Measure(s)Pre– and post–SP encounter validated confidence assessment and a 50-item content checklist (yes or no) scored by one evaluator.ResultsDuring the SP encounter, 87.3% of participants correctly diagnosed the SP actor with a lateral ankle sprain. We identified a significant improvement in confidence (P ≤ .001) for using telemedicine technology. On the content checklist, participants scored poorly in the constructs of data gathering (mean = 7.44 ± 2.36 of 15, 49.58% ± 15.75%) and telemedicine (mean = 6.02 ± 2.74 of 14, 42.99% ± 19.56%), but scored well in the constructs of communication/interpersonal skills (mean = 12.05 ± 2.00 of 15, 80.36% ± 13.36%) and patient education (mean = 4.64 ± 1.06 of 6, 77.27% ± 17.67%). The mean sum score of all constructs on the SP encounter was moderate (30.15 ± 5.79 of 50, 60.29% ± 11.59%).ConclusionsExposure to telemedicine via an SP encounter improved confidence in performing the tech-based evaluation. Athletic training students performed well in demonstrating communication/interpersonal skills and patient education, yet struggled in their data gathering and telemedicine skills. Overall, participants accurately diagnosed a musculoskeletal condition using telemedicine.

Mud House Failures and Mitigation Options in Bauchi, North East Nigeria
Authors: Ndububa Emmanuel , Mukaddas Ahmed Musa 
Published: June 2020

The use of soil materials for sustainable construction in developing countries is a viable alternative to concrete based materials. The advantages include availability of soil (earth) materials, reduction of transportation cost, saved embodied energy, reduced environmental degradation and reduced material cost. Mud house collapse is a common yearly phenomenon in Nigeria. Much of this happens during rainy seasons due to flooding generated by heavy rainfall. Whenever this happened, people were rendered homeless and became Internally Displaced Persons (IDP), with the subsequent hardships and sufferings, and sometimes casualties. Sixty seven mud houses in three locations of Bauchi town, North East of Nigeria were investigated. From observations and returns from structured questionnaires filled by house owners and tenants, about 76% of the houses had failed in form of wall collapses alone. Other data collected included age of houses, composition of wall materials and foundations. Failures were generally severe and widespread for walls of full mud houses, however those plastered with cement/sand mortar had less failure counts. Older mud houses recorded higher failures as against new constructions. Soil samples collected from borrow pits used for the investigated mud houses were tested and their soil type compositions determined in the laboratory. They slightly fell short of the specified proportional limits of clay, silt and sand considered acceptable for construction purposes except stabilized. Sample bricks made from the soils were tested for compressive strength with an average value of 0.81N/mm2 which is far below the 2.5N/mm2 minimum value for sandcrete blocks specified by the Nigerian Standards Organization. Lack of good quality control measures and improper stabilization procedures, among others were considered responsible for the failed resistance to the environmental factors. Cement stabilization and good urban planning are some of the recommendations.

Published: June 2020

Morphology and optimisation of impact energy of weldment of low alloy-high strength steel were investigated in this work. The study involved the use of design of experiment via Taguchi method based on three variables, each having three levels. Minitab 16 software was used for the analysis of variance (ANOVA) and signal to noise (S/N) ratio of the impact energy. Direct current electrode positive (DCEP) was used in the electric manual metal arc (MMA) welding. The input parameters at the three levels were current (60 A, 70 A, and 80 A), metal thickness (5 mm, 7 mm, 9 mm) and root gap (2.0 mm, 2.5 mm, 3.0 mm). It was found that the input variables significantly affected the microstructure of the weldment in all the nine experiments conducted. Optimization of welding parameters was carried out to obtain the optimal input values required to give the optimal impact energy of weldment. The optimal values for the input values were 80 A for current, 9 mm thickness and 2.5 mm root gap and these were substituted in the regression equation to obtain the optimal impact energy. It was equally observed that the input variables affected the microstructure of each of the nine samples.
Determination of Selected Moisture -Dependent Physical and Frictional Properties of Shelled Egusi Melon (Citrullus lanatus Thunb.)
Authors: Satimehin Adesola A , Akaayar Terseer M 
Published: June 2020

Physical and frictional properties were determined for shelled (i.e. hulled) seeds of egusi melon (Citrullus lanatus Thunb) at moisture content levels of 11.04, 15.7, 21.03 and 24.78 % dry basis. The physical properties investigated were true density, bulk density and the angle of repose; while the frictional properties were the coefficient of static friction and the coefficient of internal friction. Densities were determined using the volume displacement method, while the bulk porosity was calculated as a function of the true and bulk densities. The angle of repose was measured using the cylinder method. The coefficient of static friction of melon seeds on the surfaces of plywood, galvanized iron and glass was determined by sliding a cell filled with the seeds on a tilting table overlaid with the test material surfaces. The coefficient and internal angle of friction were determined by means of a shear test apparatus. Within the range of moisture investigated, the true density of shelled melon seeds decreased from 1,264 to 1,239 kg/m3 while its bulk density increased from 668 to 681 kg/m3. The porosity decreased from 47.19 to 45.36 % while the angle of repose increased from 31.0 to 34.9°. The coefficient of friction of shelled melon seeds on the surfaces of glass, galvanised iron and plywood increased from 0.329 to 0.475, 0.364 to 0.476 and 0.408 to 0.559 respectively. The coefficient and angle of internal friction increased from 0.638 to 0.668 and 32.52 to 33.74°, respectively. These findings are valuable data for efficient design of machines for processing, handling and storage of hulled seeds of egusi melon.

Published: June 2020

The purpose of this paper is to numerically investigate the effects of some geometric parameters and flow variables on heat transfer augmentation in annuli with equi-spaced internal longitudinal fins along the external walls. A fully developed flow and a constant thermal boundary condition of uniform heat flux at the walls of the pipe were assumed. Continuity, momentum and energy transport equations were adopted for the solutions of the problem. A Q-BASIC code was written based on the finite difference scheme generated. Numerical experiments were conducted to ascertain the effects of Reynolds number Re, radius ratio, R.R, Prandtl number Pr, fin height H, and pipe inclination, on the rate of heat transfer and fluid flow. The results obtained show that for 50 ≤ Re ≤ 500, total Nusselt number NuT increases with increase in Re while for Re > 500, there was no significant increase in NuT. Nusselt number, average velocity and bulk temperature of the fluid increase with increasingin the range 0° ≤ ≤ 75° but for the range 75°≤ ≤ 90° the effect is negligible. For R.R > 0.6, the heat transfer was observed to be almost independent of R; therefore for economic purposes, heat exchangers similar to the configuration studied should be run at a low pumping power. A numerical study was done to validate the program by test running it for the finless annuli for similar boundary conditions; the results obtained in the present work show the same trend as that of Kakac and Yucel.
Effects of Elevated Temperature on Splitting Tensile Strength of OPC and BLA Pozzolanic Concrete and Mortar
Authors: Ikumapayi Catherine M , Akingbonmire Samuel L 
Published: June 2020

Concrete is one of the most common and widely applied construction materials in the world. It is good in compression but weak in tension. The weakness in tension is been catered for through the use of reinforcement but there is still need to ensure that its minimum tensile strength is retained during the course of production and usage to avoid cracks development at the reinforcement cover. Concrete mixes of 1:2:4 (cement: sand: granite) and mortar of 1:6 mix ratio of cement to sand were produced. The ordinary Portland cement (OPC) content was partially replaced with bamboo leaf ash (BLA) from 0% to 12% at 2% interval. They were tested under normal and elevated temperature to know the effect of elevated temperature on their splitting tensile strength. The results obtained showed OPC concrete mix to improve in splitting tensile strength (3.5 N/mm2 to 3.7 N/mm2 at 28 days curing) whereas there was a decrease in the splitting tensile strength obtained for BLA mixes (3.29 N/mm2 to 1.75 N/mm2 for 12% percentage replacement at 28 days curing). The same trend of results was obtained for mortar mix; OPC mix increases from 1.65 N/mm2 to 1.86 N/mm2 while BLA at 12 % percentage replacement decreases from 2.02 N/mm2 to 1.7 N/mm2. OPC concrete and mortar under high elevated temperature (100oC) will improve in splitting tensile strength while elevated temperature decreases the splitting tensile of BLA concrete and mortar mixes at 12%.
Assessment of Barriers in Initiation and Completion of Isoniazid Preventive Therapy among Household Child Con-tacts of Pulmonary TB Patients in Delhi: A Mixed Method Study
Authors: Ahmed Faheem , Malik Tazean Zahoor , Islam Farzana , Muzaffar Areeba 
Published: June 2020

Background: Young children (aged < 6 years) in contact with Sputum positive TB adults are often infected with Mycobacterium tuberculosis and once infected are at higher risk of progression to TB disease than adults.
Objectives: The study was conducted To find out the proportion of < 6 years of age children having household contact of a pulmonary TB patient, screened, initiated, and completed IPT in the year 2019 and to find out the barriers for not completing/taking IPT.
Methodology: A mixed-method study was conducted during July–September 2019 among household contacts of < 6 years of age of sputum positive pulmonary TB patients attending a DOT centre in South – East Delhi.
Results: A total of 52 household contacts of less than 6 years of age were identified. Whereas 65% of the study population was aware of IPT, only 26.9% of individuals were on IPT out of the total study population and only 4 % had completed the IPT. On qualitative analysis, most of them informed that the DOTS provider didn’t emphasize them about IPT. Some of them felt that it isn’t required since the child does not have the disease.
Conclusion: Adherence to IPT is low. The dearth of IEC activities in the study area adds to this burden. Hence prompt IEC activities and adequate training of DOT providers for initiation and adherence of IPT is the need of the time.
