Création d’un dispositif de groupe à médiation thérapeutique dans un service médico-pénitentiaire : jouer à imaginer l’histoire
Authors: Burdeau Sandie , Ravit Magali
Published: December 2022

Cet article présente la mise en place d’un dispositif de prise en charge groupale à destination de patients incarcérés auteurs de violence. Face à une pensée dite « opératoire », il paraît indispensable de construire un dispositif invitant le sujet à se raconter. Nous avons proposé un groupe à médiation thérapeutique par le conte. C’est autour de l’histoire que la médiation offre une associativité focale propice aux échanges groupaux. En appui sur la structure du récit, les patients tissent une première trame narrative leur permettant de se situer de manière réflexive vis-à-vis de leur vécu subjectif. Nous présenterons plusieurs séquences d’un groupe mis en place lors de notre pratique de psychologue clinicienne en service médico-pénitentiaire. Elles illustrent comment le conte permet de saisir les premiers vécus d’effraction psychique. Le fil associatif se tisse entre des images issues du conte et celles du vécu subjectif des patients, montrant comment le conte s’offre comme trame interne pour permettre une première mise en récit.
L’écriture comme outil thérapeutique
Authors: Francese Erica
Published: December 2022

L’écriture en tant que médium possède une dimension interrelationnelle : elle est adresse à l’autre, et/ou à l’autre en soi. Mais elle a aussi une dimension intrapsychique : elle oblige à se mettre en contact avec ses sensations, ses représentations, ses affects pour les transformer en mots lisibles aux autres. Elle est traduction de soi à l’autre. Nous utilisons ces dimensions intrinsèques à ce médium pour que l’écriture, sa lecture, les échanges qu’elle suscite deviennent une source d’associativité et de réflexivité, pour que la distanciation impliquée dans la traduction en mots devienne élaboration psychique. De la projection dans le texte du transfert diffracté par le dispositif à l’introjection des contenus psychiques élaborés ensemble, de l’acting au texte, du texte à la parole, nous illustrerons le fonctionnement de notre groupe d’écriture avec quelques vignettes cliniques.
Fonctionnement incestuel dans l’institution
Authors: Mathonnat Christine
Published: December 2022

L’incestuel constitue le ferment des pathologies trans-psychiques et trans-générationnelles fixées dans une organisation perverse. Dans l’enceinte familiale incestuelle, chacun – parent/ infans  – adresse à l’autre l’exclusivité de son investissement érotique. Dans l’institution, l’incestuel effracte les rapports institués en désorganisant les logiques psychiques de subjectivation. Psychologue au sein d’une institution de la mésincription, nous analyserons le fonctionnement d’un lieu d’hébergement pour adultes déficients mentaux où se déploient les formes d’une jouissance incestuelle. Mythe familialiste, idéologie matriarcale, endogamie, investissement réifiant les corps et nomination désubjectivante y révèlent l’ en-plus d’une dynamique pulsionnelle signant l’abolition de la limite. Il reste à inventer des stratégies qui soutiendront la rencontre intersubjective – entre professionnels et professionnels-résidents – et partant, viseront l’appropriation subjective.
Une névrose de destinée familiale : clinique des maladies rénales génétiques et héréditaires
Authors: Jean-Dit-Pannel Romuald , Belot Rose-Angélique , Vidal-Bernard Alexandra , Sanahuja Almudena
Published: December 2022

L’hypercomplexité des enjeux cliniques liés aux insuffisances rénales chroniques et à leurs traitements palliatifs, la dialyse et la transplantation, est renforcée par ses formes génétiques et héréditaires. Des accumulations d’annonces se succèdent et sont les conséquences de conjonction(s) explosive(s) au sein d’un corps familial en proie à des répétitions, soumis à la vampirisation d’une névrose de destinée familiale. Avec le cas d’Élisabeth, nous interrogeons les effets singuliers et familiaux des transmissions inter- et transgénérationnelles de la filiation. Les complexités familiales de ces situations cliniques posent en effet d’innombrables questions autour des origines et des vécus de la maladie, ainsi que des thérapeutiques. Cela reste toujours en voie d’historicisation, sur les plans individuels, conjugaux, fraternels et filiaux. Nous discuterons du groupe, du corps familial comme d’une matrice mortifère dans cette clinique. Puis nous conclurons sur la question du désir d’enfant au sein de cette clinique : signe-t-elle une bonne santé psychique – singulière, de couple et familiale – ou une part active de la répétition d’une destinée familiale subie passivement ?
Le secteur médicosocial : des origines à nos jours
Authors: Borgetto Michel
Published: December 2022

S’il a fallu attendre le déclenchement de la Révolution pour que soient posés – via le principe de l’assistance obligatoire – les premiers jalons de ce qui deviendra plus tard l’action sociale et médicosociale, ce n’est cependant qu’à la fin du siècle suivant que sera durablement consacré le principe de l’assistance obligatoire, pierre de touche du futur secteur médicosocial. Celui-ci, depuis lors, n’a cessé de s’étendre et de se développer, si bien que le législateur a dû intervenir à plusieurs reprises pour définir et préciser les principales règles régissant son mode d’organisation et de fonctionnement. Reste cependant à se demander, au terme de plus de deux siècles d’histoire, ce qui spécifie le secteur médicosocial et en construit l’identité et, au-delà, ce qui à la fois le rapproche et le distingue des deux autres secteurs qui lui sont connexes : le secteur sanitaire d’un côté, et le secteur social de l’autre…
APA et PCH : le rapprochement est-il possible ?
Authors: Piveteau Denis
Published: December 2022

L’allocation personnalisée d’autonomie (APA) et la prestation de compensation du handicap (PCH) sont, depuis le début des années 2000, les deux prestations individuelles majeures de compensation de la perte d’autonomie, qu’elle survienne lors du grand âge, ou par un handicap survenu au début ou au cours de la vie. Elles relèvent d’une même et forte inspiration qui a conduit, il y a deux ans, à l’émergence d’une nouvelle branche du régime général de la sécurité sociale : le « risque autonomie ». Mais si leur existence donne ainsi concrètement corps à ce « cinquième risque » de sécurité sociale, le fait qu’elles visent chacune un public placé de part et d’autre de l’âge-pivot de 60 ans interroge. En se plaçant du seul point de vue, objectif, des modalités de leur attribution, on constate que, si elles se ressemblent par bien des aspects qui permettent de les regarder comme définissant une catégorie nouvelle de prestations, à mi-chemin des formes canoniques de la sécurité sociale et de l’aide sociale, elles présentent aussi des différences importantes qui font qu’elles ne relèvent pas d’inspirations identiques. Une conclusion s’en déduit qui est que la fameuse « barrière d’âge » qui les sépare n’est sans doute pas prête de tomber. Car il est impossible d’envisager une convergence purement paramétrique : APA et PCH définissent, au-delà de leurs parentés d’intention, deux univers distincts qui ne pourraient pas aisément fusionner.
Chroniques du grand isthme : origines et enjeux géopolitiques de la guerre en Ukraine
Authors: Motte Martin
Published: December 2022

L’unification de l’isthme Baltique-mer Noire, successivement réalisée par la Rus’ de Kiev, l’État polono-lituanien et la Russie, s’est avérée au cours de l’histoire un puissant atout géopolitique. L’Ukraine est la zone la plus disputée de cet isthme, non seulement par les acteurs locaux, mais aussi par les puissances maritimes (tour à tour la France, le Royaume-Uni et les États-Unis), désireuses de protéger leurs intérêts méditerranéens contre une menace sortie de la mer Noire. Tout ceci éclaire l’actuel conflit en Ukraine
Les opérations terrestres en Ukraine : la guerre conventionnelle parfaite ?
Authors: Henrotin Joseph
Published: December 2022

La guerre d’Ukraine démontre l’importance de facteurs centraux en stratégie : forces morales, facteurs humains, importance d’une stratégie des moyens adaptée, planification. Du point de vue des opérations terrestres, elle est également classique en montrant le rôle du facteur temps et de la dialectique entre offensive et défensive qui permet au faible d’être plus efficace que le fort. Elle démontre enfin l’immaturité du processus russe de réforme des armées, qui n’explique cependant pas toutes les erreurs de Moscou.
La guerre aérienne en Ukraine : guérilla ou guerre de haute intensité ?
Authors: de Lespinois Jérôme
Published: December 2022

Malgré une très nette supériorité de moyens, les forces aériennes russes n’ont pas réussi à conquérir la supériorité aérienne en Ukraine pour des raisons qui tiennent à la culture stratégique de l’armée de l’air et de l’espace russe, au caractère inachevé de leur modernisation et à la mise en œuvre par les Ukrainiens d’une puissante défense sol-air. Cette situation a permis aux Ukrainiens de mener une sorte de guérilla aérienne et de remporter, grâce notamment à l’emploi de drones, une série de victoires tactiques pendant les premières phases du conflit. La contre-offensive lancée par l’armée ukrainienne montre qu’elle s’est préalablement appuyée sur des opérations de conquête de la supériorité aérienne dont l’ampleur n’est aujourd’hui pas complétement connue mais qui s’est appuyée sur l’aide matérielle et l’expertise de ses alliés occidentaux. La guerre en Ukraine illustre ainsi la permanence des principes de la stratégie aérienne mais aussi les nouvelles formes de la conflictualité aérienne du fait notamment du développement des drones et de leur intégration à tous les échelons de la manœuvre des forces.
Les opérations navales durant la guerre d’Ukraine
Authors: Henrotin Joseph
Published: December 2022

Bien que numériquement inférieure, la marine ukrainienne a été en mesure d’adopter des modes d’action centrés sur l’interdiction maritime, avec pour conséquence d’entraver la liberté d’action russe, tout en ayant un effet notoire sur les opérations terrestres.
Du stockage physique à la valorisation numérique des archives photographiques de presse
Authors: Le Maître Stéphanie
Published: December 2022

Cet article s’intéresse aux réinvestissements dont font l’objet les stocks d’archives photographiques de presse. Les stratégies de valorisation numérique au sein desquelles ils sont insérés par des acteurs publics comme privés les présentent comme des documents historiques, des composants d’une œuvre artistique ou comme des objets de décoration. Quelle que soit la stratégie déployée, ils sont très largement coupés de leur fonction initiale, au détriment d’une appréhension complète.
Newspaper storage: infrastructures, places, practices. A media archaeological expedition into German newspaper studies in the early 20th century
Authors: Koenen Erik
Published: December 2022

Dans l’histoire des études de communication, les approches matérielles jouent rarement un rôle et n’ont pas été systématiquement explorées. Cet article vise à mettre au jour les premiers concepts matériels autour du journal dans les études allemandes sur les journaux au début du xx e siècle. Plus qu’aujourd’hui, les journaux étaient alors considérés comme des artefacts contenant des connaissances inhérentes qu’il fallait rendre accessibles et tangibles. Dans cette optique, les collections de journaux sont apparues comme des infrastructures et des espaces spécifiques pour l’archivage, la collecte, le stockage, la préservation et le traitement des journaux, offrant un accès matériel à la génération de connaissances. Ces développements seront étudiés en liant l’archéologie des médias et l’épistémologie historique à une perspective « pratique » d’histoire des sciences.
Le « stockage dynamique » d’une « archive active ». Les stratégies d’Artpool en matière de stockage et de diffusion d’informations sur l’art underground depuis les années 1970
Authors: Barkóczi Flóra
Published: December 2022

Cet article vise à présenter les stratégies de stockage et de diffusion d’Artpool, une archive d’art créée en 1979, lors de la période socialiste en Hongrie. Illustrant les diverses pratiques de stockage et de diffusion de matériel dans les différents contextes politiques de ces quarante dernières années – d’une archive underground créée illégalement à la muséalisation de la collection –, l’étude se penche sur le programme d’Artpool, fondé sur l’idée d’« archive active », et montre ses liens avec le concept de « stockage dynamique », introduit récemment par Wolfgang Ernst.
From the Vaults: Unboxing Analogue Film Storage
Authors: Venturini Simone
Published: December 2022

Au cours de la dernière décennie, on a assisté en Europe à une augmentation de la construction de nouveaux centres de conservation, ultramodernes et axés sur le design. Ces entrepôts de films peuvent être redécouverts comme un environnement dynamique qui redéfinit et remodèle continuellement les artefacts qui y sont stockés. Loin du simple rangement de boîtes de films sur une étagère, la préservation des films consiste à inscrire l’objet filmique dans un réseau complexe d’infrastructures médiatiques, de procédures d’archivage, de croyances partagées et de techniques culturelles.
Du groupe à l’équipe de travail – Dépasser les risques de rupture
Authors: Meynckens-Fourez Muriel
Published: December 2022

Cet article reprend quelques fondamentaux pour tenter de garder cohérence et cohésion au sein d’une équipe œuvrant dans les champs psycho-médico-sociaux, et ce malgré les embûches. Dans un premier temps, il aborde l’organisation d’un groupe, tant en ce qui concerne les professionnels que les bénéficiaires, pour ensuite relater quelques difficultés, rappeler quelques incontournables utiles au fonctionnement d’une équipe et approfondir l’une ou l’autre balises apportées. Le dispositif de supervision est aussi abordé. L’auteur fait honneur tant aux pionniers de la systémique avec des éléments de la première cybernétique qu’aux tenants de la seconde cybernétique. Il invite à un processus réflexif.
Is There Gender Bias in Perceptions of Strabismus Among Adults?
Authors: Thuma Tobin B. T. , Gunton Matthew , Zhang Qiang (Ed) , Sharpe James , Gunton Kammi B.
Published: December 2022

Purpose:

To investigate the effect of gender, type, and size of horizontal deviation on the perceived severity or need for intervention for strabismus among adults in the general population.

Methods:

Eight photographs of individuals aged 25 to 35 years were digitally manipulated to create 30 prism diopters (PD) of exotropia, 30 PD of esotropia, 50 PD of exotropia, and 50 PD of esotropia in both men and women. A survey asked respondents to rank these photographs by their severity or need for intervention from 1 (greatest need) to 8 (least need) to assess for unconscious bias for gender, strabismus type, or deviation size.

Results:

A total of 203 adult respondents completed the survey. Participants ranked men with both large esotropia and large exotropia (median rank = 1.5, interquartile range [IQR] = 1.5 to 1.5) as needing correction more urgently than similar women (median rank = 3.5, IQR = 3.5 to 4) (
P
< .0001). The median rank was 4 (IQR = 3.75 to 4.25) for all men combined and 5 (IQR = 4.75 to 5.25) for all women (
P
< .0001). Photographs with exotropia (median rank = 4, IQR = 3.75 to 4.5) were perceived as more severe than photographs with esotropia (median rank = 5, IQR = 4.5 to 5.25) (
P
< .0001). Respondents' gender, age, or history of strabismus did not significantly impact their rankings.

Conclusions:

Male photographs were perceived as having a greater need for strabismus intervention than female photographs despite similar type and size of deviations. Exotropia was perceived as more severe than esotropia for smaller deviations only. More studies on the perceptions of strabismus are needed to understand whether unconscious bias affects patient care.

Two-Color Dark-Adapted Perimetry Implemented With a Commercially Available Perimeter to Characterize Rod-Pathway Sensitivity
Authors: Igelman Austin D. , Park Jason C. , Hyde Robert A. , Everett Lesley , Yang Paul , Pennesi Mark E. , McAnany J. Jason
Published: December 2022

Background and Objective:

To characterize rod-pathway function across the visual field using 2-color dark-adapted perimetry (2cDAP) implemented with conventional Octopus 900 Pro perimeters.

Patients and Methods:

Eighteen visually normal individuals and two retinitis pigmentosa (RP) patients participated. Thresholds were measured under dark-adapted conditions at 15 locations along the horizontal meridian using short (450 nm) and long (610 nm) wavelength stimuli. Threshold differences between the two wavelengths were used to determine rod- vs cone-mediated function.

Results:

Among controls, peripheral and perifoveal thresholds for the short-wavelength stimulus were approximately 2 log units lower than for the long-wavelength stimulus. Foveal thresholds for the two wavelengths were similar. RP threshold profiles differed considerably from the controls, with normal foveal thresholds and high peripheral thresholds for both wavelengths.

Conclusions:

2cDAP can be performed with an unmodified Octopus perimeter to evaluate rod function across the visual field and obtain information that is not available with standard automated perimetry.

Placement analysis of combined renewable and conventional distributed energy resources within a radial distribution network
Authors: Gill Amandeep , Singh Pushpendra , Jobanputra Jalpa H. , Kolhe Mohan Lal
Published: December 2022

System islanding, relay tripping, and reverse power flow-like issues in the distribution network are all caused by randomly placed distributed energy resources. To minimize such problems, distributed energy resource (DER) optimal placement in the radial distribution network (RDN) is essential to reduce power loss and enhance the voltage profile. When placing DERs, consideration of constraints like size, location, number, type, and power factor (PF) should be considered. For optimal placement, renewable and nonrenewable DERs are considered. The effects of different types and PFs of DER placements have been tested on the IEEE 33 bus RDN to satisfy all limitations. Using various intelligent techniques, distributed energy resource units of optimal type, PF, size, quantity, and position were placed in the IEEE 33 bus RDN. These intelligent strategies for minimizing power loss, enhancing the voltage profile, and increasing the convergence rate are based on an adaptive neuro-fuzzy inference system, a genetic algorithm, and enhanced particle swarm optimization.
Investigation of chaotic behavior and adaptive type-2 fuzzy controller approach for Permanent Magnet Synchronous Generator (PMSG) wind turbine system
Authors: Sambas Aceng , Mohammadzadeh Ardashir , Vaidyanathan Sundarapandian , Mohamad Ayob Ahmad Faisal , Aziz Amiral , Mohamed Mohamad Afendee , Sulaiman Ibrahim Mohammed , Nawi Mohamad Arif Awang
Published: December 2022

This article begins with a dynamical analysis of the Permanent Magnet Synchronous Generator (PMSG) in a wind turbine system with quadratic nonlinearities. The dynamical behaviors of the PMSG are analyzed and examined using Poincare map, bifurcation model, and Lyapunov spectrum. Finally, an adaptive type-2 fuzzy controller is designed for different flow configurations of the PMSG. An analysis of the performance for the proposed approach is evaluated for effectiveness by simulating the PMSG. In addition, the proposed controller uses advantages of adaptive type-2 fuzzy controller in handling dynamic uncertainties to approximate unknown non-linear actions.
Uniqueness for a Cauchy problem for the generalized Schrödinger equation
Authors: Gölgeleyen İsmet , Kaytmaz Özlem
Published: December 2022

In this work, we consider a Cauchy problem for the generalized Schrö dinger equation which has important applications in quantum kinetic theory, water wave problems and ferromagnetism. Due to its multidimensionality, it is important from the point of view of modern physics theories such as quantum field theory and string theory. We prove the uniqueness of the solution of the problem in an unbounded domain by using semigeodesic coordinates. The main tool is a pointwise Carleman estimate. To the authors' best knowledge, this is the first study which deals with the solvability of this problem.
Bayesian inference in epidemics: linear noise analysis
Authors: Bronstein Samuel , Engblom Stefan , Marin Robin
Published: December 2022

This paper offers a qualitative insight into the convergence of Bayesian parameter inference in a setup which mimics the modeling of the spread of a disease with associated disease measurements. Specifically, we are interested in the Bayesian model's convergence with increasing amounts of data under measurement limitations. Depending on how weakly informative the disease measurements are, we offer a kind of 'best case' as well as a 'worst case' analysis where, in the former case, we assume that the prevalence is directly accessible, while in the latter that only a binary signal corresponding to a prevalence detection threshold is available. Both cases are studied under an assumed so-called linear noise approximation as to the true dynamics. Numerical experiments test the sharpness of our results when confronted with more realistic situations for which analytical results are unavailable.
Effective difference methods for solving the variable coefficient fourth-order fractional sub-diffusion equations
Authors: Pu Zhe , Ran Maohua , Luo Hong
Published: December 2022

This paper is concerned with the numerical approximations for the variable coefficient fourth-order fractional sub-diffusion equations subject to the second Dirichlet boundary conditions. We construct two effective difference schemes with second order accuracy in time by applying the second order approximation to the time Caputo derivative and the sum-of-exponentials approximation. By combining the discrete energy method and the mathematical induction method, the proposed methods proved to be unconditional stable and convergent. In order to overcome the possible singularity of the solution near the initial stage, a difference scheme based on non-uniform mesh is also given. Some numerical experiments are carried out to support our theoretical results. The results indicate that the our two main schemes has the almost same accuracy and the fast scheme can reduce the storage and computational cost significantly.
La «lingüística del humor» y el estudio de los juegos de palabras en la Biblia Hebrea
Authors: El Ammari Alonso Sel·lam
Published: December 2022

La verificación de la presencia de juegos de palabras en la BH es un asunto controvertido, pues varían entre los especialistas los criterios para: 1) su definición, 2) su clasificación y 3) el discernimiento de sus funciones. Este artículo repasa diversos acercamientos al fenómeno en los estudios bíblicos, incidiendo en la disparidad de los criterios empleados y de los términos y las clasificaciones resultantes. Se quiere mostrar el modo de operar biblista comparando sus enfoques y métodos con otros de la lingüística actual, por lo que, previamente, se presentarán algunos resultados de la lingüística generativa en el terreno de los juegos de palabras para ilustrar: 1) las diferencias en percepción, catalogación y caracterización del juego de palabras entre la lingüística y los estudios bíblicos y, derivado de ello, 2) mostrar un posible camino a seguir por estos.
L’Histoire Naturelle comme manifeste identitaire ? Quelques remarques sur les provinces et leur image chez Pline l’Ancien
Authors: Vial-Logeay Anne
Published: December 2022

Souvent connu pour son allégeance à Rome et au pouvoir impérial qu’il servit fidèlement, Pline l’Ancien, lorsqu'il compose son Histoire naturelle, décrit l’oikoumène en recourant aux documents administratifs que sont les formulae prouinciarum, de même qu’il intègre ponctuellement à son enquête des connaissances fournies, entre autres sources, par les provinces. Il ne semble pas pour autant considérer celles-ci comme détentrices d’une identité propre, quitte à paraître reconduire, voire aggraver, une forme d'altérité entre l’Vrbs et ses périphéries sans tenir grand compte des subdivisions administratives qui nourrissent pourtant sa pratique professionnelle. Ainsi, L. Cornelius Balbus peut-il être qualifié d’externus, tandis que la Narbonnaise, elle, se voit louée comme étant "plutôt l'Italie qu'une province". À rebours, Pline paraît s'attacher à mettre en évidence les rapports instaurés par le Princeps avec les habitants de l’empire romain comme permettant d’instaurer un nouveau langage politique recevable par chacun d'entre eux, car fournissant une image paradoxalement égalitaire, résumable dans la métaphore de la ruche organisée autour d'un "roi". Les provinces, objet du volume, seraient donc le point aveugle ou l'un des points aveugles d'une pensée à la fois romanocentrique et universalisante, attachée à penser le dépassement par Rome de la vieille opposition entre Grecs et Barbares.
Embuer l’État
Authors: Corroyer Pablo
Published: December 2022

À Bure (Grand Est), des acteurs étatiques, chargés de mettre en œuvre un projet nucléaire, font face à des militant·e·s dits « autonomes » qui, à l’inverse d’autres mobilisations, cherchent à maintenir l’opacité de leurs actions. Une part importante de l’activité militante consiste ainsi à contester les stratégies et dispositifs par lesquels l’État veut restaurer la lisibilité du territoire disputé. À partir d’une enquête ethnographique, l’article s’attache donc à comprendre la formation d’un régime d’action collective relativement à celle d’un certain ordre politique et territorial.
Analysis on the Corrosion of the Inner Cavity of the Christmas Tree Hydraulic Valve in a Well in Western China

Published: December 2022

In this paper, with the observing corrosion morphology of the inner cavity of the Christmas tree hydraulic valve and detecting the physical and chemical properties of the material (chemical composition, mechanical properties and metallographic structure),It is found that the main reason for the corrosion of the inner cavity of Yidong fan is that in the production process, due to improper heat treatment process, Cr element is accumulated in the metallographic structure of the hydraulic valve matrix, forming a grid like high Cr region, and the grid becomes a low Cr region, under the action of formation water containing CO2, the low Cr area is corroded, and large and deep corrosion pits are formed in the internal cavity of the hydraulic valve.
Study the Fatigue Corrosion Behavior of Turbine Blade by Laser Cladding
Authors: Abdulwahab Zaman Abdulrazaq , Jafar Sami I. , Ajeel Sami A.
Published: December 2022

The turbine blades utilized in this investigation were made of alloy steel type 52, the same steel used in electric power plants. The current research aims to study the effect of corrosion fatigue behavior on turbine blades when cyclic loads and corrosion work together to degrade a material's mechanical properties. As a result, many engineering structures and components experience early failure. Laser cladding is a method of laser surfacing to improve or rejuvenate the surface of an object. This parameter was used in the cladding process. 132 watts of laser power, with a peak output of 1.83 kilowatts, was used to generate the pulses, with each pulse containing 11 joules of energy. The results reveal that the specimen's microstructure is smoother following the laser cladding procedure and that the corrosion fatigue resistance in the air (without solution) is increased. This paper will look at how laser cladding impacts turbine blades.
Material Wear Calculation of Braking Surface under High-Power Braking Conditions
Authors: Sha Zhi Hua , Hao Qiang , Yin Jian , Liu Yu , Zhang Sheng Fang , Wang Yan An
Published: December 2022

The wear phenomenon of the braking surface of a high-power disc brake under emergency braking conditions is analyzed in this paper. Considering the classical Archard wear model, including the influence of the braking load, speed, and friction coefficient on the braking surface, the wear model of the brake disc surface is established to obtain the wear depth and distribution. It is essential to investigate the wear mechanism of the brake disc surface, and the evolution of wear laws is revealed under different braking parameters. The results have shown that the brake disc surface wear is constantly accumulating. The large load, the high speed, and the large friction coefficient would aggravate the surface wear area. It is expected that the wear study of the brake disc surface can guide the design of the disc brake.
Effect of Direct Rolling of Without-Heating on the Differentiation of Mechanical Properties of Rebar
Authors: Liu Xin , Song Bao Yu , Zhao Yang , Liu Xu Ming , Wang Jun Sheng
Published: December 2022

This paper focuses on the mechanical property differentiation and phase content differentiation of HRB400 rebars under the direct rolling of without-heating (DROW) process. The results showed that the temperature distribution from the head region to the tail region of the billet before rolling under the DROW process was different compared to the traditional hot rolling (THR) process, which resulting in the difference of each phase volume fractions and the grain size of the rebar. Compared with the THR process, the phase distribution of the rebars under the DROW process is not uniform, showing the characteristics of low ferrite content in the head region, followed by the tail region, and the highest in the middle region. It was demonstrated that the DROW process could improve the mechanical properties of the rebar, but the difference in phase content and grain size distribution leads to a large variability in the enhancement of the mechanical properties of rebar rolled in different areas of the billet.

Authors: Ernawati Lusi , Reza Mutia , Synthia Adela Clara , Kartikasari Dwi Aprilia , Maharsih Inggit Kresna , Halim Abdul
Published: December 2022

Dye pollutants are commonly found in waste water, posing a health risk. Adsorption is a potential technique for dye removal, because of its long-term viability, bio-adsorption is favored. Bio-adsorbent derived from local sources provides a long-term production supply. However, there is a wide range of bio-adsorption, which leads to differences in bio-adsorbent kinetics and characteristics. Tanjung fruit (Mimusops Elengi) peels are used to make activated carbon with a large specific surface area and high porosity. This fruit is one of the readily accessible native fruits in East Kalimantan. The effects of three activators (H3PO4, NaCl, and KOH) were studied. Characterization and analysis is conducted by Scanning Electron Microscopy (SEM) for surface morphology analysis and BET method for porosity analysis.The results reveal that acid activation (H3PO4) was successful in producing highly porous activated carbon, which has greater adsorption performance than salt (NaCl) and alkaline activation (KOH). The use of salt (NaCl) as an activating agent resulted in a greater development of broad porosity during the activation thermal treatment that followed. The carbon was activated at 500°C had a BET surface area of 587.59 m2g-1 and a pore size of 28.27 ml g-1, respectively. For isothermal and kinetics, the Langmuir model and pseudo-first-order reaction are the best fit models. Our findings provide important information on the guided synthesis of large-surface-area, extremely porous activated carbons from local biomass waste, which has a potential for adsorptive dye removal.

Published: December 2022

Pulsed laser ablation in liquid (PLAL) is considered a relatively fast, simple to manipulate, cost-effective abraoch, and enables the fabrecation of multiscale micro-nanostructures in one step, facilitating the fabrication process. Copper nanoparticles solution was prepared by PLAL technique using Nd:YAG laser in deionized water at (532 nm), (1000 pulse), and the energies (700 mJ, 800 mJ, 900 mJ, and 1000 mJ) with a fixed distance between the laser source and the sample, fixed amount of liquid, and the liquid rise above the copper was (5 mm). The effect of the excess of the laser energy in the preparation process was tested by analyzing the optical properties of the fabrecated samples by UV-Visible spectrophotometer, SEM, XRD, and EDX measurements.
Boriding Treatment of Low Alloy Steels: Effect of Holding Time and Temperature
Authors: Kermiche Younès , Benarioua Younès
Published: December 2022

Boriding is a thermochemical treatment that can be applied to improve the mechanical and chemical properties of steels by surface modification while stilling adequate substrate properties. This kind of treatment is widely used to protect the degradation of the mechanical parts’ surface against wear. The boride atoms introduced into the steel can produce a hard metallic compound formed by diffusion and precipitation. The present study has been conducted in order to obtain an iron borides layer on two types of steel substrates 16NC6 and 20MC5 by using a powder consisting of B4C, NaBF4 and, SiC. The solid boriding treatment was carried out in an electric furnace heated to 950°C for three holding times of 2h, 4h and, 6h. The present research work focuses an the effect studying of holding time as a parameter on the thickness, structure, morphology, and hardness of layers obtained on low carbon steels by the case boriding. As confirmed by structure and microstructure characterization, the hard boride layers produced form two phases of FeB and Fe2B.

This paper investigates the valorization of slag in cement production in order to obtain a sustainable mortar and participate in protecting the environment. The study evaluated the setting time, hydration heat, mechanical strengths, drying shrinkage, sulfuric acid and sulfate attack of mortars. These mortars are based on Portland cement (PC), slag cements containing 10%, 30% and 50% slag and alkali-activated slag (AAS) using 6% and 9% of sodium hydroxide (NaOH). The results show that the increase in slag replacement rate increases the setting time accompanied by a drop in initial mechanical strength such that the compressive strength decreased by 30% at two days for a 50% slag substitution; also, it considerably reduces the shrinkage and hydration heat. The resistance to sulfate and sulfuric acid attack increases with the slag replacement rate. NaOH-activated slag mortar is the most resistant binder to sulfate attack and sulfuric acid, but it develops a lower mechanical strength and a more significant shrinkage than PC mortar. X-ray diffraction (XRD) analysis carried out on binder paste shows the formation of the same main hydration products in PC and slag cement with a small amount of portlandite in the last binder. Calcium silicate hydrate (CSH) and Hydrotalcite are the main hydration products of AAS.

Coffee is a caffeinated beverage that is well known worldwide and its existence continues to grow. Only 10% of coffee is consumed and the rest become spent coffee grounds, previous research has shown that spent coffee grounds can be used as bio-absorbent, bio-diesel and bio-battery. In this study, we will synthesize bio-batteries made from spent coffee ground. This research will treat spent coffee grounds with hydrochloric acid (HCl) at a dilution concentration of 30%, 50%, and 70%, and dried at a temperature of 200°C; 300°C; and 400°C. The result indicated that the variation a HCL dissolution variation of 50% (with combination of all variation of drying) lasted up to 52 days with a maximum power of 0.024 W. Characterization using X-Ray Diffraction (XRD) at variation of 300°C,50% shows peak at 2θ = 28.92°, other variation shows 2θ = 28.32° (200°C,50%), and 2θ = 28.68° (400°C,50%). Morphology of the spent coffee ground (300°C,50%) observed using Scanning Electron Microscope (SEM) EDX, it shows that the structure is in the form of fused flakes like carbon with visible porosity. From these data, spent coffee grounds with treatment of HCl could be considered to be the next-generation electrolyte for batteries in the future.

Published: December 2022

Additive manufacturing can provide advantages over conventional manufacturing for alloys such as alloy 625, which is expensive and difficult to machine. Laser powder bed fusion is a type of additive manufacturing that provides advantages but introduces complex effects on mechanical properties in produced components. This work examines some of these effects by assessing laser powder bed fusion processing parameters, several heat treatment schedules, and differing strain rate and temperature testing behavior using mechanical testing. It was determined that the porosity of fabricated samples of alloy 625 could be reduced below the control of 0.43 %, though the hardness does not appear to be sensitive to processing parameters. Heat treatments at higher temperatures appear to maintain a similar hardness to as-printed samples, but a treatment at 670 °C increased the hardness from 28.0 to 31.3 HRC. In compression tests, samples had higher stress/strain ratios in the dynamic range, though they did not fracture in any tests conducted. In a range from 25 to 500 °C, samples displaced a consistent thermal softening effect, suggesting that significant microstructural change may not occur, compatible with the typical high temperature working conditions of the alloy.

Metal oxide electrode materials have relatively high theoretical capacitance. However, structure, morphology and composition of this kind of materials have significant influence on electrochemical performance. Moreover, metal oxide electrode materials have problems of low power density and cyclic stability. In this work, Mo-doped hydroxide zinc carbonate material (Mo-HZC) is synthesized on foam Ni surface by hydrothermal method. This Mo-doping electrode exhibits typical pseudocapacitance. Specific capacitance of Mo-HZC in 1.0 mol L-1 KOH is 698.9 F g-1 (1.0 A g-1), which is 2.5 times that of the undoped sample. The maximum energy density and power density of Mo-HZC electrode are 32.1 WH kg-1 and 3.16 KW kg-1, respectively. Assembled Mo-HZC//AC capacitor exhibits a long-term cycling performance with remains 79.5% capacitance retention within 20 000 cycles at 1.0 A g-1.
“Killing a Demon”: The Use of Cultural Symbols in Therapeutic Work with Children- A Case Report
Authors: Peeligama H. M. C. D. K. , Attygalle U. R.
Published: December 2022

This case report describes how family conflict, and a lack of parental support for emotional expression, result in distress being expressed through cultural symbols in children, and how these very symbols can be utilized in therapy. In the current example, a 12-year-old girl presented to mental health services with altered behaviour and claims of being possessed by a demon for two months. There was a history of the parents being emotionally unavailable and frequent altercations with the paternal grandmother in whose house they currently lived. Even though possession states are not uncommon in adults presenting to mental health services, it is uncommon for children to present with persistent possession states for long periods of time. In this instance, the whole family was supported with an eclectic family therapy approach, using psychodynamic, Cognitive Behaviour Therapy, and Systemic ideas. This approach utilized the very same “demon” symbol the child presented with, and resulted in the child expressing her distress in a more adaptive way and getting back to her daily activities.

Bromhidrosis has a great negative impact on personal occupation and social psychology. It is not yet clear whether bromhidrosis is caused by apocrine sweat glands or the co-action of apocrine sweat glands and eccrine sweat glands. To distinguish between apocrine sweat glands and eccrine sweat glands, specific antigen markers for apocrine sweat glands and eccrine sweat glands must be found first. In the study, we detected the expression of K7, K18, K19, Na+-K+-2Cl- cotransporter 1 (NKCC1), carbonic anhydrase II (CAII), Forkhead transcription factor a1 (Foxa1), homeobox transcription factor engrailed homeobox1 (En1), gross cystic disease fluid protein-15 (GCDFP-15), mucin-1 (MUC-1), cluster of differentiation 15 (CD15) and apolipoprotein (APOD) in eccrine sweat glands and apocrine sweat glands by immunofluorescence staining. The results showed that K7, K18, K19, Foxa1, GCDFP-15 and MUC-1 were expressed in both apocrine and eccrine sweat glands, CD15 and APOD were only expressed in apocrine sweat glands, and CAII, NKCC1 and En1 were only expressed in eccrine sweat glands. We conclude that CD15 and APOD can serve as specific markers for apocrine sweat glands, while CAII, NKCC1 and En1 can serve as specific markers for eccrine sweat glands to differentiate the two sweat glands.

L’identità dell’umano tra “differenza” e “origine”
Authors: Canzi Elena , Iafrate Raffaella
Published: December 2022

Il presente contributo, facendo riferimento al modello relazionale-simbolico di Eugenia Scabini e Vittorio Cigoli, propone alcune riflessioni intorno al tema della “differenza” e dell’“origine”, come elementi costitutivi dell’identità dell’umano, che hanno come luogo primario di realizzazione la famiglia (sul versante sia del rapporto tra i generi, sia della relazione tra le generazioni) e che ne sostengono la spinta generativa.
Tra autonomia e responsabilità. La filosofia del diritto e la legislazione sul “diritto di morire”
Authors: Palazzani Laura
Published: December 2022

L’articolo analizza le problematiche del fine vita in bioetica dal punto di vista della filosofia del diritto, analizzando criticamente i percorsi della legislazione e della giurisprudenza italiani più recenti. In particolare, la Legge 219/2017 viene analizzata con riferimento al rifiuto e alla rinuncia alle cure salvavita, all’ostinazione terapeutica, alla sedazione profonda, alle direttive anticipate di cura e la pianificazione anticipata dei trattamenti. L’autore analizza i problemi bioetici e biogiuridici sul tema del “lasciar morire” e “uccidere”, con riferimento alla sentenza 242/2019 della Corte Costituzionale che ammette il suicidio medicalmente assistito in deroga all’art. 580 cp, a determinate condizioni. La sentenza 50/2022 della Corte Costituzionale sull’inammissibilità del cosiddetto referendum sull’eutanasia consente di individuare altre riflessioni bioetiche sui temi con riferimento alla tutela minima della vita e alla vulnerabilità.
Nonobstetric lower genital tract injury patients of a tertiary care center in Eastern Uttar Pradesh, India
Authors: Aditya Vani , Mishra Richa , Tiwari Harish Chandra
Published: December 2022

Background:

Injuries of lower genital tract are commonly seen in obstetrics patients during labor and delivery. Nonobstetric genital injuries are seen less commonly. Research on injuries to the lower genital tract from nonobstetric trauma is therefore scant. The purpose of this study was to document causes, treatment, and outcomes among patients of lower genital tract injuries visiting to B. R. D. Medical College and Nehru hospital, Gorakhpur, U.P.

Methods:

Admission and operation theater registers of the department of obstetrics and gynecology during 1 year were scrutinized for cases admitted with the diagnosis of genital trauma. Bed-head tickets of patients were scrutinized with the help of a data abstraction form, and information regarding age, cause of injury, site, size and pattern of injuries, treatment, and short-term outcome were recorded.

Results:

Of a total of 43 cases of traumatic genital tract injuries, 39 women received treatment. Maximum cases were seen in girls aged 6–10 years. Three women were pregnant at the time of injury. Noncoital injuries predominated over coital injuries, i.e., 59% versus 38.4%. Among the noncoital injuries, fall was the most common cause accounting for 75% of the cases. Coital injuries following consensual sex occurred more commonly in women who were sexually active, lactating, or postmenopause. The chief presenting complaint was vaginal bleeding. Vaginal wall laceration/tear was the most common injury reported. Multiple injuries were seen in 40% (17/39) of the cases. Twenty-one cases of laceration/tear (53.8%) were repaired surgically of which seven required examination and repair under anesthesia. Vulvar hematomas were managed by incision and drainage. There was no major morbidity or mortality.

Conclusions:

The results of this study from eastern Uttar Pradesh, India, support those from other developing nations. Noncoital injuries were found to be the most predominant cause of non-obstetric genital trauma, though, contrary to others, children were seen to be at the greatest risk. It is important to teach children about playing safely and following safety measures while on the road. We must also make them aware so that they do not become victims of rape.
