Porcine Collagen Transconjunctival Wound Closure System for Microincisional Vitrectomy Surgery
Authors: Chen Tiffany A. , Kaiser Peter K. , Fasching Rainer , Moshfeghi Darius M.
Published: November 2023

BACKGROUND AND OBJECTIVE:

Microincisional vitrectomy surgery has improved outcomes for vitrectomies; however, wound closure complications remain an important concern. The authors introduce a technique to improve transconjunctival wound closure in vitrectomy surgery.

PATIENTS AND METHODS:

The authors evaluated the efficacy of porcine collagen plugs on stopping leakage from sclerotomy test sites in vitro and in vivo and assessed wound site healing with histology samples.

RESULTS:

The porcine collagen plugs successfully prevented leakage of trypan blue dye in enucleated rabbit eyes and of fluid flow in the rabbit model. Histology showed excellent wound reconstruction and healing, with essentially no inflammation for either angled or straight incisions with a 23-gauge system.

CONCLUSIONS:

The authors describe a simple and effective novel approach to wound closure in any-gauge vitrectomy surgery using porcine collagen plugs. This method can help reduce complications related to wound leakage. The authors plan to conduct human studies to demonstrate the safety of the approach in the future.

De la discorde à l’entente
Authors: Serra Enrico
Published: November 2023

Camille Barrère fut ambassadeur de France à Rome pendant un quart de siècle (de 1897 à 1924) : c’était un temps où les ambassadeurs n’étaient pas de simples exécutants des instructions du Quai d’Orsay, mais de vrais conseillers des Ministres, bien plus éphémères dans leurs fonctions. Son rôle dans les relations internationales ne fut pas mince puisqu’il contribua à éviter que l’Italie entre en guerre aux côtés de l’Allemagne et de l’Autriche-Hongrie et à faire qu’elle rejoigne la Triple Entente.
Sur son action, l’auteur Enrico Serra qui partageait avec Barrère sa passion du journalisme, écrivit en 1950 un livre d’histoire diplomatique à la fois savant et élégant. Utilisant toutes les sources alors disponibles ainsi que plusieurs archives privées, l’auteur arrive à des conclusions qui ont été confirmées par les recherches les plus récentes. Il nous offre une œuvre pleine de perspicacité et de sympathie pour l’hôte du Palais Farnèse, tout en ne cachant pas les foucades de ce Républicain à la fois épris de la grandeur de la France et attaché au rapprochement des sœurs latines.
Par amitié pour Serra (avec lequel il avait fondé et animé le Comité franco-italien d’études historiques), et par admiration pour Barrère, ce diplomate exceptionnel qui avait tenu tête à Clemenceau, Jean-Baptiste Duroselle avait entrepris la traduction de ce livre. Plus d’un demi-siècle plus tard, voici donc cette étude enfin disponible en français.
Stratégies identitaires, stratégies d’effacement : le dilemme constitutif des littératures de genre
Authors: Luis Raphaël
Published: November 2023

Cet article se propose d’étudier les tensions constitutives aux littératures de genre via une répartition entre deux grands types de stratégies, qu’on appellera stratégies identitaires et stratégies d’effacement. À travers l’étude de plusieurs exemples de discours sur le genre, on montrera que ces stratégies sont à considérer à toutes les échelles de la production et de la consommation, des auteurs aux critiques en passant par les lecteurs et les éditeurs.
La (re)catégorisation en « littérature de jeunesse » entre geste auctorial, stratégie éditoriale et ambiguïtés de la réception. Les cas de Patrick Chamoiseau et d’Évelyne Trouillot
Authors: Franchini Pauline
Published: November 2023

Patrick Chamoiseau et Évelyne Trouillot font partie des auteurs et autrices de la Caraïbe francophone qui publient à la fois des ouvrages destinés aux adultes et des contes et romans pour la jeunesse. Néanmoins, la publication des recueils de contes créoles de Patrick Chamoiseau dans des collections « jeunesse » relève davantage d’une stratégie éditoriale que d’un geste auctorial et d’un projet délibéré d’écrire pour les enfants. Quant au roman Rosalie l’infâme d’Évelyne Trouillot, si tout porte à croire qu’il n’a pas été spécifiquement écrit pour un jeune lectorat, certains éléments du texte et du paratexte favorisent une re‑catégorisation inattendue en « jeunesse » au niveau de la réception critique et des usages en classe. Au-delà de la poétique des textes, ces traversées de frontières éditoriales dans le domaine des littératures francophones postcoloniales interrogent à nouveaux frais le statut de « littérature mineure » et la définition même de la littérature de jeunesse, entre genre littéraire à part entière et catégorie éditoriale.
De l’effacement de l’auteur de genre au geste autobiographique comme stratégie de réaffirmation du moi de l’écrivain : l’exemple d’Agatha Christie et de Jean Meckert
Authors: Vervel Marc
Published: November 2023

Si la tradition bourdieusienne use du terme de « stratégie » pour rendre compte de l’ensemble des effets de circulation à l’intérieur d’un champ, ce terme peut aussi renvoyer très concrètement aux moyens déployés par les écrivains associés au « genre » pour maîtriser leur ethos et réinvestir la fonction-auteur ; alors que la littérature de genre, associée à la culture médiatique se donnant sous le signe de la sérialité, tend à récuser l’identité et le « nom » d’auteur ou à en faire l’équivalent d’une pure marque, il est intéressant de constater à cet égard que certains écrivains, associés notamment au roman policier, ont pu proposer à l’occasion au lecteur une autobiographie, ou en tout cas — tant la frontière entre autobiographie et autofiction peut s’avérer ici difficile à établir — déployer ce qu’on appellera un geste autobiographique dans des textes au statut parfois incertain, mais qui se donnent en tout état de cause selon des modalités différentes du reste de l’œuvre de leurs auteurs. On se penchera ici sur le cas d’Agatha Christie et de Jean Meckert, écrivains très différents mais confrontés tous deux à un rapport problématique aux questions de la mémoire et de l’identité, et aux problématiques croisées qui peuvent dès lors se lire dans leurs textes respectifs. Ce qui se lit ici de diverses manières, c’est de fait un ensemble de motifs et de moyens destinés à détourner les enjeux attendus du récit autobiographique pour mettre en scène une image d’écrivain en prise avec l’art et l’imaginaire créateur.

Authors: Saint-Amand Denis
Published: November 2023

Cet article est consacré au Trombone illustré, périodique pirate présenté comme un supplément de l’hebdomadaire Spirou. Accueilli dans les pages de ce dernier au fil de trente livraisons en 1977, il se donne à voir comme une expérience dissidente impliquant la mise en place d’une stratégie contestataire et critique au cœur d’une institution de la bande dessinée. Il s’agit d’esquisser ici une lecture sociopoétique de cet objet, interrogeant les logiques normatives en régime paralittéraire, les possibilités de perturber ces dernières et les limites posées à ces forces perturbatrices.
The Giver, sur la crête de la censure et du succès : les stratégies auctoriales de Lois Lowry
Authors: Mallah Sarah
Published: November 2023

Cet article traite du célèbre roman The Giver de l’autrice étasunienne Lois Lowry publié en 1993, qui a fait polémique en raison de ses thématiques considérées comme perturbantes pour les jeunes lecteurs. Il propose un bref examen du texte et expose sa réception contrastée, qui doit être comprise dans le cadre du système social et politique américain de la fin du xxe siècle. Par la suite, l’article considère les positionnements stratégiques de Lowry pour faire face à la censure, ainsi que les mécanismes culturels et les postures de l’autrice pouvant expliquer la popularité durable de l’œuvre. Ces analyses informent sur la manière dont s’articulent la construction d’une identité auctoriale chez une écrivaine pour la jeunesse, et le développement d’une certaine culture médiatique dans les années 1990 et 2000.
Resistance Spot Welding of QP Stainless Steels: Role of Heat Treatment and Microstructure on Joint Strength
Authors: Smith Ali , Macia Eric , Muratori Marta , Sierra-Soraluce Andrés , Sabirov Ilchat
Published: November 2023

QP steels and other third generation AHSS possess outstanding combinations of strength and ductility, making them very attractive for the automotive sector. However, an Achilles heel of these materials is their rather limited weldability. Despite the obvious importance of this problem, very few works have been published characterising 3rd generation AHSS welded joints. For the current contribution, 3 novel QP stainless steels were investigated. Resistance spot welded joints were prepared following QP treatment of sheets. Results following paint baking revealed a high nugget hardness and a microstructure of martensite, retained austenite and delta ferrite. Cross tension strength was highest for the alloy with an optimum dispersion of retained austenite which improved weld metal toughness despite the high hardness. A further improvement in cross tension strength was realised on tempering at high temperatures, leading to an 60% improvement in strength, thanks to improved toughness of the martensite constituent.
Back-Annealing of Hot Dip Galvanised Strip Steel Microalloyed with Vanadium
Authors: Steyn Johannes Sebastian , Banks Kevin Mark , Siyasiya Charles Witness
Published: November 2023

Back-annealing during the hot dip galvanising (HDG) process was applied to heavily cold-worked low C-microalloyed VN steels in an attempt to achieve a yield strength of 700 MPa and a minimum A80 elongation of 10 percent. HDG simulations were performed to compare recovery and recrystallisation kinetics in VN steel with that experienced in plain low C and Nb-Ti grades. Based on these results, an industrial melt was subjected to conventional hot rolling, cold rolling and back-annealing cycles during HDG. Precipitation in both VN and Nb-Ti steels extended the recovery window by about 75 degrees Celsius when compared to that found in low CMn steel. A temperature-time parameter M was used to compare the rates of softening. The Mrs (recrystallisation start) in both VN and Nb-Ti steels was 20.1 compared to 18 in a low CMn grade. The above properties were achieved by subjecting low C-microalloyed VN steel to low finishing and low coiling temperatures followed by back-annealing heavily cold-worked strip to a maximum temperature to prevent full recrystallisation. The softening rate during annealing is higher in both microalloyed steels than the CMn grade, with recrystallisation being completed more rapidly in the VN steel. Laboratory results implied insensitivity of restoration behaviour to hot rolling parameters whilst industrial results suggest that they are effective.
Design and Properties of Hot Rolled Tough Carbide Free Bainitic Steels
Authors: Rana Radhakanta , Cordova-Tapia Erick , Morales Rivas Lucía , Garcia-Mateo Carlos
Published: November 2023

Carbide free bainitic microstructures of steels in hot rolled condition have high potential for automotive and structural applications, where both high elongation and toughness at a high strength level are needed. However, achieving a combination of these properties remains a challenge due to difficulties in ensuring a high stability of retained austenite while maintaining industrial processability. Therefore, an attempt has been made in this work to achieve combined high toughness and high elongation in hot rolled carbide free bainitic steels.
Effect of Ferrite/Austenite Phase Transformation on 475 °C Embrittlement in Duplex Stainless Steel Weld
Authors: Saida Kazuyoshi , Yamashita Shotaro , Hirata Hiroyuki
Published: November 2023

The change in hardness due to 475°C embrittlement was investigated in the melt-run GTA welds of type 329J4L duplex stainless steel. A ferritic phase was hardened with ageing at 673-773K due to the phase decomposition into Fe-rich and Cr-rich phases, while an austenitic phase was barely hardened with ageing. Hardness in a ferritic phase was rapidly increased with ageing in the base metal (BM) region, and the hardening rate was reduced in the order of BM, weld metal (WM) and heat affected zone (HAZ). The ferrite/austenite fractions in HAZ and WM were higher than that in BM, furthermore, Cr content in a ferritic phase was lowered and Ni content in it was contrarily heightened in the same order of BM, WM and HAZ. A computed phase diagram suggested that the chemical composition of a ferritic phase in each region was located in the nucleation/growth region not spinodal decomposition region, which was situated between the spinodal and binodal lines. Computer simulation of phase decomposition phenomena in a ferritic phase using phase field model revealed that phase decomposition was accelerated with an increase in Cr content and a decrease in Ni content. It followed that Cr would enhance the 475°C embrittlement and Ni would inhibit it, because of the increased/decreased driving force of the phase decomposition. The difference in 475°C embrittlement behaviour at each region could be attributed to the difference in the chemical composition of a ferritic phase caused by the ferrite/austenite phase transformation during welding.
Prediction of TTR Diagrams via Physically Based Creep Simulations of Martensitic 9-12% Cr-Steels

Published: November 2023

This work deals with the prediction of time-to-rupture (TTR) diagrams of martensitic 9-12% Cr steels. Martensitic 9-12% Cr steels are state of the art materials for powerplants due to their high creep strength and oxidation resistance. Since the experimental determination of TTR diagrams is costly and time-expensive (minimum 10 years), it is of particular interest to be able to model TTR diagrams and gradually replace experiments. Here, we approach the question to what extent we can generate a TTR diagram of a material out of a fraction of experimental results plus detailed understanding of the underlying microstructural/physical phenomena during creep. Our model is based on dislocation creep and includes multiple interactions between the microstructural constituents. We show the applicability of our approach by reproducing a TTR diagram of the well-known material P92. Input parameters are basic material data from literature, the starting microstructure before creep, chemical composition, some model parameters determined on the similar material P91, and one single creep curve of P92. The precipitate evolution is simulated by the software MatCalc, the other microstructural constituents (dislocation densities, subgrain boundaries etc.) by our creep model. By varying the stress between individual creep simulations whilst keeping all input parameters (starting microstructure, temperature and material parameters) constant, we produce multiple creep curves and thus generate the complete dataset for a TTR diagram. The model is of particular interest when it comes to the development of new materials, as the application range of these materials can be estimated quickly and with good reproducibility.
Microstructural Characteristics and Mechanical Properties of Nanostructured Bainite Processed through High and Low Temperature Ausforming and Isothermal Holding near Ms in a Medium Carbon Steel
Authors: Ghosh Sumit , Kaikkonen Pentti , Somani Mahesh Chandra , Kömi Jukka I.
Published: November 2023

Laboratory rolling simulations, comprising of thermomechanically controlled rolling followed by ausforming and isothermal holding close to Ms temperature, were conducted on a medium-carbon (C) steel in order to understand the combined effect of prior straining and low temperature holding on the bainite transformation characteristics and resultant properties. Field emission scanning electron microscopy (FE-SEM) was employed to examine the morphology, size and volume fraction of different phase constituents and the observed microstructural features were correlated with the mechanical properties of the steels. The morphology of bainite and/or retained austenite (RA) after low temperature ausforming was found to be extremely fine compared to the sample ausformed at high temperature. An excellent combination of high yield (~1200 MPa) and tensile (~1800 MPa) strengths, good ductility (~18 %) and reasonable ambient temperature impact toughness (~15 J/cm2) were achieved in the low temperature ausformed steel that was attributed to significant refinement of bainite sheaves and presence of high fractions of film-like RA. The dislocations introduced by ausforming hindered the growth of bainite and promoted enhanced carbon diffusion, resulting in high fractions of finely divided film-like RA with high stability. Recent results obtained on a nanostructured /ultrafine medium-carbon bainitic steel elucidating the ausforming conditions and corresponding microstructures and properties are illustrated here.
Tribological Behaviour of Low Temperature Plasma Assisted Carburized 316 L Steel Produced by L-PBF Technique

Published: November 2023

Austenitic stainless steels produced by Laser Powder Bed Fusion (L-PBF) are interesting materials because of their excellent corrosion resistance. Due to their relatively low hardness, the tribological response of these materials is poor, which limits their use in applications where control of wear degradation is important. Nevertheless, low-temperature plasma-assisted carburisation is an interesting process for improving the wear resistance of austenitic stainless steels, as has been observed for wrought materials. In fact, the increase in hardness is guaranteed by a surface layer of expanded austenite (S-phase) with a thin top layer of amorphous carbon. In this work, AISI 316 L, produced by the L-PBF technique, was carburised using 5 different plasma gas mixtures (by varying the CH4/H2 ratio) at 475°C for 7 hours. The samples obtained were then subjected to a detailed microstructural characterisation in order to obtain information on surface modification. The morphological features of the surface were examined by SEM observations in top view and in cross-section. The tribological performance was evaluated by pin-on-flat tests (alumina sphere as counter-material) with 2 different applied loads and a stroke length of 5 mm. Friction coefficient, wear rate (stylus profilometer) and wear mechanisms (SEM) were also evaluated. Preliminary results show an increase in wear resistance of all plasma treated materials compared to the untreated material. The improved tribological performance was discussed in relation to the abrupt increase in surface hardness.
Influence of Hot Rolling Practice and Furnace Residence Time on the Strength and Toughness of Normalised Nb-Ti-V Structural Steel Plate
Authors: Maubane Dannis Rorisang Nkarapa , Banks Kevin Mark , Kurup Vinod
Published: November 2023

The influence of moderate thermomechanical rolling and heat treatment time on the microstructure and mechanical properties of normalised Ni-containing Nb-Ti-V microalloyed plate steels was investigated. Conventional rolling (CR) and low austenitic temperature rolling (TM) schedules were applied to 25 and 55mm thick plates. Predicted plate thermal profiles were used to simulate normalising of 25 and 55mm thick plates at the mid-thickness. As expected, the microstructure after TM rolling was finer due to austenite sub-structure development below the no-recrystallisation temperature which increases the amount of ferrite nucleation sites. The tensile strength of the CR plates was generally higher due to a larger pearlite volume fraction resulting from slow cooling from a relatively coarse austenite. In 25mm plate, the presence of acicular ferrite after CR resulted in a higher yield strength than that obtained after TM rolling. Furnace residence times of 0.75min/mm and longer allowed for plates to be completely normalised – characterised by continuous, well-defined polygonal ferrite grain boundaries. Short furnace residence times restricted the plate temperature to below the end of the ferrite-to-austenite transformation (Ac3), where untransformed ferrite is retained from the as-rolled microstructure and is characterized by poorly defined grain boundaries. Rolling practice and normalising residence time had little to no effect on impact toughness, but significantly influenced the normalised yield strength of thicker plate.
High Energy Density Welding of IN792 Ds Superalloy
Authors: Barbieri Giuseppe , Cognini Francesco , de Crescenzo Chiara , Fava Alessandra , Moncada Massimo , Montanari Roberto , Richetta Maria , Varone Alessandra
Published: November 2023

Ni base superalloys are commonly employed in the industrial fields of aerospace, automotive and energy production due to their excellent mechanical properties and corrosion resistance at high temperature. Superficial defects and cracks may occur during both manufacturing process of components and their service life. High energy density welding techniques, electron beam (EBW) and laser beam (LBW) welding, can be used to create efficient repairs. Joints, obtained by EBW and LBW of IN792 directionally solidified (DS) superalloy, have been investigated to determine the presence of defects, and evaluate the mechanical properties related to specific microstructural features. The results showed that a pre-heating temperature (PHT) higher than 200 °C is always necessary to prevent the formation of hot cracks in the molten zone (MZ) and heat affected zone (HAZ). The process parameters have been optimized to get a good quality of the seams (lack of macro-defects, a good penetration depth and width). Some preliminary test of post-welding heat treatments (PWHTs) have been investigated to homogenize as far as possible the microstructure and the mechanical properties across the seams. The results obtained by the two techniques, EBW and LBW, have been compared and discussed.
Development and Application of a Thermal Microstructure Model of Laminar Cooling of an API X70 Microalloyed Steel

Published: November 2023

A thermal microstructure model of laminar cooling of X70 microalloyed steel skelp was developed to predict the effect of the laminar cooling temperature profile on the through thickness skelp microstructure. Plant trials using infrared video imaging were undertaken to establish the laminar cooling conditions prevalent in the industrial cooling system. The infrared video temperature measurements were used to develop a finite element thermal model of the skelp transiting the entire laminar cooling system. Dilatometer testing of the X70 steel with cooling rates ranging from 1 °C/s to 120 °C/s was undertaken to develop the CCT curve and to quantify austenite decomposition. The predicted thermal profile from the finite element model and the phase transformation behaviour were combined into a thermal microstructural model capable of predicting the phases that would develop through the skelp thickness as a function of the laminar cooling profile. The predicted through thickness microstructures were verified from electron backscattered diffraction (EBSD) phase analysis of industrially produced API X70 skelp.

В наших недавних работах было дано конструктивное описание пространства орбит $G_{n,2}/T^n$. В этом результате важную роль играют понятия комплекса допустимых многогранников $P_\sigma$, пространств параметров $F_\sigma$ и универсального пространства $\mathcal{F}_n$ параметров $T^n$-действия на $G_{n,2}$.
В настоящей статье получена явная конструкция пространства $\mathcal{F}_n$ методом замечательной компактификации. На основе этой конструкции и описания пространства $\overline{\mathcal{M}}(0,n)$ из работы Киля мы получили явный диффеоморфизм между $\mathcal{F}_n$ и $\overline{\mathcal{M}}(0,n)$. Таким образом, получена реализация фактора Чжоу $G_{n,2}//(\mathbb{C}^{\ast})^n$ в виде пространства $\mathcal{F}_n$ со структурой, в описании которой участвуют допустимые многогранники $P_\sigma$ и пространства $F_\sigma$.

A semi-empirical model for magnetic storm dynamics
Authors: Benella Simone , Consolini Giuseppe , Stumpo Mirko , Alberti Tommaso
Published: November 2023

The near-Earth electromagnetic environment represents a far-from-equilibrium system characterized by sudden irregular energy relaxation events. For a broad class of complex systems, time series can be interpreted in terms of a superposition of stochastic and deterministic components occurring at different time scales. In this work we use the generalization of the SYM-H index provided by the SuperMAG collaboration (SMR), which is meant for monitoring the global variation of the horizontal component of the Earth’s magnetic field in the near-equatorial regions. The aim of this work is to model the SMR dynamics via stochastic differential equations thus providing a semi-empirical model whose parameters are retained from data. As a first step we test the Markov condition on the SMR data sample, which represents the basic condition for our stochastic modeling, and we show that such a requirement is accurately satisfied by SMR time series. This allows us to infer the model parameters for the SMR index through the Kramers–Moyal analysis. Finally, we give evidence that a purely diffusive process is not representative of the observed dynamics and then a model based on jump-diffusion processes must be considered to correctly reproduce the dynamical features of the SMR index.

Les tribunaux d'opinion face à l impunité des crimes de masse: quelle légitimité pour quelle effectivité?
Authors: Montavon Camille
Published: November 2023

Les six dernières décennies témoignent d’une prolifération de tribunaux d’opinion établis par la société civile en vue de dénoncer, analyser et reconnaître des situations de violations massives des droits humains ignorées par les systèmes de justice étatiques et internationaux. Or, ces dispositifs demeurent largement méconnus et, surtout, absents du droit positif comme de la doctrine juridique majoritaire. L’autrice s’attache à expliquer ce décalage en interrogeant le bien-fondé des principales critiques opposées à ces mécanismes de justice alternative, soit celles de leur illégitimité et de leur ineffectivité. Pour ce faire, elle se base sur l’expérience de quinze tribunaux d’opinion créés en contexte d’impunité de crimes de masse.

Nelayan di Tanjung Tiram masih menggunakan alat tangkap ikan yang selektif dimana dalam pengoperasian alat tangkap ikan nelayan tersebut masih dapat menangkap ikan dalam skala jumlah yang banyak, sedangkan berdasarkan penilaian tingkat keramahanan lingkungan berada pada nilai 30,76 pada nilai tersebut dapat diartikan bahwa tingkat keramahan lingkungan tergolong kurang ramah lingkungan, hal ini diperkuat karena adanya aktivitas penangkapan dengan menggunakan alat tangkap kerang yang menggunakan kapal atau biasa disebut “tangker” dimana dalam pengoperasiannya hampir merusak ekosistem yang ada dan menjadi pusat konflik dikehidupan nelayan di Tanjung Tiram.
