Radiolucent Implants for Fixation of Impending and Pathologic Fractures
Authors: Krumme John W. , MacConnell Ashley E. , Adams Brock W. , Jelinek James J. , Henshaw Robert M.
Published: February 2022

Radiolucent implants offer theoretical advantages of increased ability to evaluate the fracture site for healing and recurrence and potentially less effect on radiation treatment, avoiding scatter. Their clinical utility and outcomes have yet to be proven in a well-designed randomized trial or large cohort study, although studies based on other indications have shown relative safety and they are approved by the US Food and Drug Administration for treatment of pathologic fractures. Further research is necessary to better understand when and how these implants should be implemented in practice. [

Corneal Irregularity After LASIK Induced by Eyelid Disease
Authors: Chanbour Wassef , Brenner Jason , Melki Samir
Published: February 2022

PURPOSE:

To describe an unusual case of lower eyelid cystic lesions inducing irregular astigmatism and a decrease in visual acuity following laser in situ keratomileusis (LASIK) surgery.

METHODS:

A 32-year-old woman presented with decreased vision and foreign body sensation. She underwent uncomplicated LASIK, followed by an enhancement procedure 2 months prior to her visit. Uncorrected distance visual acuity was 20/80 with a refraction of +1.25 −0.75 × 135°, correcting her visual acuity to 20/30.

RESULTS:

Examination showed inferior punctate keratitis. Thinning and flattening were noted on topography. Epithelial mapping showed inferior epithelial thinning and nasal thickening. Further evaluation identified multiple asymptomatic cystic lesions on the lower eyelids. The patient was diagnosed as having mechanical pressure-induced corneal flattening and thinning. A bandage contact lens was used, the cornea returned to its regular shape, and there was no recurrence after lesion excision.

CONCLUSIONS:

LASIK may have weakened the biomechanical properties of the cornea and predisposed the eye to pressure-induced corneal irregularities. A bandage contact lens proved to be protective. Screening for eyelid disease is advised before and after LASIK.

On the spherical geopotential approximation for Saturn
Authors: Haziot Susanna V.
Published: February 2022

In this paper, we show by means of a diffeomorphism that when approximating the planet Saturn by a sphere, the errors associated with the spherical geopotential approximation are so significant that this approach is rendered unsuitable for any rigorous mathematical analysis.
Le Recueil Lauvergne (1680) de Claude Barbin. Écriture en groupe ou coup d’éditeur ?
Authors: Bung Stephanie
Published: February 2022

Publié en 1680, le Recueil de poésies par Madame de Lauvergne, dédié à Madame la Marquise de Neuville, dit Recueil Lauvergne est un ouvrage composite dont la facture nous renseigne sur les enjeux sociaux qui informent beaucoup de procédés éditoriaux de l’époque. Ces enjeux peuvent prendre la forme de l’écriture en groupe, dans le domaine de la poésie galante notamment. L’éditeur de la compilation, Claude Barbin, en est bien conscient puisqu’il équipe son livre d’une dédicace qui semble nous renvoyer à un milieu privilégié, voire à une relation de patronage précise. Cet article vise à interroger cette scénographie du collectif littéraire sans pourtant la dénoncer comme pure fiction. Car si « effet de groupe » il y a, c’est que l’exclusivité de tels groupes n’est pas inventée, mais qu’elle est dessinée à contre-jour dans le Recueil Lauvergne.
Le « trio » de farceurs de l’Hôtel de Bourgogne. Penser la construction du collectif théâtral
Authors: Kerautret Flavie
Published: February 2022

Cet article s’intéresse à la construction du collectif théâtral par l’écrit à partir du cas du « trio » de l’Hôtel de Bourgogne, soit de trois comédiens (Gros Guillaume, Gaultier-Garguille et Turlupin) devenus l’incarnation de la farce française du début du xviiᵉ siècle aux yeux de l’histoire théâtrale. Distincte de la troupe comme configuration sociale, l’image du « trio » s’instaure à travers divers écrits littéraires qui particularisent ces acteurs comiques de leur vivant et, surtout, au moment de leur mort. Les publications concernant le « trio » se sont effectivement multipliées après le décès de Gaultier-Garguille, fin 1633, si bien que l’avènement du groupe s’avère lié à un effet de génération et à un geste de commémoration. Ce cas permet ainsi de réfléchir à l’articulation du singulier et du collectif en étudiant la façon dont s’instaure le succès d’un petit groupe par l’imprimé et certains mécanismes du vedettariat.

Authors: Raut Umesh K. , Vishwamitra L. K.
Published: February 2022

The proposed multi-layer ECDH based authentication model, the vehicles in the VANET are authenticated and authorized to protect the network from the attacks for which the vehicles undergo the registration process initially. After the successful registration, the messages generated from the vehicles are communicated with each other through multi-step authentication, which assures the exactness of the received messages. Then, the authorization process is executed in the VANET so as to ensure the safe and secure interactions between the vehicles. The implemented authentication model is analyzed using the comparative methods based on the performance standards, such as detection accuracy, execution time, packet delivery ratio (PDR) and throughput. The detection accuracy, execution time, PDR and the throughput of the network while executing the proposed multi-level ECDH based authentication system is better than the prevailing security models as the security features of the existing models are enhanced better than the existing state-of-art methods.

Authors: Mezaal Abdulrahman Mohammed , Najim Khalid Battal , Noaman Ahmed Tareq
Published: February 2022

The tire manufacturing sector occupies a significant portion of the global economy. The production of vehicle tires requires the utilization of different raw and processed materials. Steel beads are one of these main ingredients, used to reinforce the treads and sidewalls of car tires. In this study, the effect of incorporating steel fibers cut from discarded bead wire (DBW) during the tire manufacturing process on the rheological, mechanical, and flexural toughness of high-strength self-compacting concrete (SCC) was investigated. Four SCC mixes were prepared with four discarded bead wires, at volume fractions of 0%, 0.3%, 0.6%, and 1%. Four lengths of the discarded bead wires were used in the term of hybridization: 10, 20, 30, and 35 mm. These were mixed together, with each length comprising 25% of the total. Investigations of fresh and hardened concrete properties were carried out. The results showed that discarded bead wires affected the rheological properties of the high-strength SCC adversely, causing a considerable reduction in slump flow and passing ability and an increase in T500 and V-funnel time, and enhancing segregation resistance. On the other hand, the mechanical properties, such as compressive strength and splitting tensile strength were improved significantly with the inclusion of the discarded bead wire. Moreover, investigations of flexural toughness based on ASTM requirements were conducted. Overall, the presence of different lengths of the discarded bead wire helped to transfer the load from the cementitious matrix to the short fibers, and then to the long ones, leading to the enhanced energy absorption capacity of high-strength SCC.

The expansion in the application of bio-materials leads to a wide variety of forms. The current study includes the preparation of a biological material in the form of a bio-coating that is represented by the, combination of a substrate with biological properties and at the same time high mechanical properties represented by alumina and the use of a coating from a material that provides high biological properties and low mechanical properties if it compared with the substrate, which is the hydroxyapeptite . Hydroxyapeptite was prepared from the biological waste, which is the egg shells after chemically cleaning by acetone solution and drying them in air , grind for 14 hours then calcination at 850 Co for 2hours, and reacting with phosphoric acid ,heat treatment by sintering at 1100Co, for 3 hours to obtain the pure hydroxyapatite phase. After preparing cylindrical samples of alumina and sintering them at a temperature of 1300°C and coating them by immersion with a solution of hydroxyapeptite prepared from mixing of hydroxyapeptite with of distilled water, the immersion is done at intervals ranging from (10,30,and 50 ) minutes, sintering process for soaking sample has been done at 1200 Co for one hours. The XRD and EDS technique showed an increase in the proportion of hydroxyapatite coatings formed and appears in calcium and phosphorous ions with an increase in the immersion time. Degradation test has been done after soaked the samples in Buffer solution for 7 days which proved increment in degradation as the soaking time increase .
Effect of Friction Modelling on Damage Prediction in Deep Drawing Simulations of Rotationally Symmetric Cups
Authors: Nick Matthias , Müller Martina , Voigts Herman , Weiser Ingo Felix , Herrig Tim , Bergs Thomas
Published: February 2022

The damage state in a formed component has a significant influence on the performance of the component in service. Controlling damage evolution during forming through specific modifications of the process parameters will therefore allow an improvement of this performance. The evolution of the stress-strain state during the forming process is the primary influencing factor of the resulting damage state. The stress-strain state is influenced by the friction between tools and workpiece. To investigate the cause-effect relationship between friction and damage evolution in the deep drawing process, Finite Element simulations of the deep drawing of rotationally symmetric cups were performed. Punch velocity and blank holder force were varied. Damage was predicted using a Lemaitre damage model. The damage states predicted using a Coulomb friction law and a model incorporating a dependence on contact normal stress and relative velocity were compared. The parameter-dependent friction model predicted a change in the damage distribution after forming when varying the process parameters, which was not found using the Coulomb friction law.
Research on Tribological Performance of Inconel 625 with Micro-textures
Authors: Chi Yong Rui , Luo Peng , Ding Chun Long , Xu Hu , Chen Jun Yong , Li Yuan
Published: February 2022

Improving the tribological properties of Inconel 625 is of great significance for its application in slewing bearing and bearing parts of mechanical transmission system in nuclear power plants. In this study, the tribological properties of textured surface (GTSs) and smooth surface (SS-20) of Inconel 625 under different loads during dry sliding friction were researched. The results show that GTSs improves tribological properties of Inconel 625 obviously. The friction coefficient of GTSs is lower than that of SS-20. The grooves on GTSs play a role in capturing wear debris during the friction process, which improve the contact surface characteristics between counterpart ball and substrate, leading to the reduction in wear loss. When the load is 20 N, the Inconel 625 with textured surface has the best tribological performance. The excessive load will cause the big deformation of material and decrease the capacity of capturing wear debris of grooves, resulting in the accumulation of debris and the severe wear of wear track.

Published: February 2022

Nanocomposites (NCs) (100-x) SrFe12O19/x Co (x = 10, 20, and 30 wt. %) were produced using the high energy ball-milling (HEBM) process. The effects of hard/semi-hard ratio and annealing temperature (800, 900, and 1000 °C) on the exchange-spring in magnetic NCs were discussed. X-ray diffraction examination showed the coexistence of M-type hexaferrite SrFe12O19 (SFO) as the hard phase and CoFe2O4 spinel ferrite (CFO) as the semi-hard phase. Using a scanning electron microscope (SEM), the morphology and elemental analysis of the NCs were analyzed. The magnetic performances were investigated via a vibrating sample magnetometer at room temperature. With increasing the CFO content and annealing temperature, the hysteresis loop became narrower and possessed semi-hard magnetic properties. The 10 wt. % Co NCs annealed at 800 °C had the highest coercivity of Hc = 4.2 kOe. These results are correlated with switching field distribution plots that have indicated the efficient exchange-spring between SFO and CFO phases NCs annealed at 800 °C. The studied samples can be a promising candidate in permanent magnets and magnetic recording media applications.

Published: February 2022

In this study, an experimental investigation of the effect of addition of Alumina (Al2O3), Zinc Oxide (ZnO), and Silicon Oxide (SiO2) particles powders on the mechanical behavior and crystallinity of the PLA films was carried. Granulated of Polylactic acid (PLA) and ceramic powders with different concentrations were prepared to form PLA/ZnO and PLA/ZnO-SiO2-Al2O3composites films using a solvent casting process. Morphology of PLA and composite films were examined by optical microscopy, chemical and crystal structures of composites are analyzed by (ATR-FTIR) spectroscopy and XRD techniques. Tensile strength and young modulus are determined by traction test. The obtained result by optical microscopy shows the micrograph of PLA samples with different composition are evenly distributed on the film surface. The intensity of the absorption band located at 754 cm-1which correspond to the crystalline phase of PLA is verified by the ATR-FTIR characterization. The XRD diffraction shows that the ceramic particles influence on the peaks intensity of PLA films localized at 19.5 ° C and 22.5 ° C, which indicate an augmentation in the crystallinity of the composite films. Mechanical tests show Tensile strength and Elasticity modulus are improved after the addition of Oxide Particles to Polylactic acid films.
Coarse-graining Mean and Displacement of Granular Matter
Authors: Xie Guang Qi , Wang Huan You
Published: February 2022

In this paper, we emphasize that the thermodynamic basis of displacement concept is finite equilibrium region and quasi-static process. By considering the dynamic process of a particle system undergoing reversible deformation under external force, the spatial and temporal distributions of mesoscopic mass, mesoscopic mass flow, mesoscopic energy, and mesoscopic stress are calculated using corresponding mesoscopic theory (e.g., Hertz contact mechanics). Their macroscopic correspondence is calculated by means of coarse-grained average, and the resulting macroscopic mass and mass flow are substituted into the equation that defines the displacement, and the displacement is calculated by integration.

Authors: Hu Xing , Ding Can , Feng Lu
Published: February 2022

In order to analyze the influence of Al-Ag doping on the electrical properties of eigenstate and oxygen vacancy ZnO resistor valves, first principles were used to analyze the crystal structure of Al-Ag single doping and co-doping eigenstate and oxygen vacancy ZnO. Energy, band structure, density of states and electrical conductivity have been calculated. The results show that after doping with acceptor elements, the lattice parameters of the eigenstate unit cell and the oxygen vacancy unit cell are increased, and their potential can be increased. Gradient; when Ag is doped, its formation energy is the lowest, indicating that Ag doping is easier and higher stability; when oxygen vacancies, the nonlinear characteristic of ZnO resistor valve is better than that of eigenstate, but whether it is single doping or Co-doping does not improve its nonlinear characteristics better; doping will slightly increase its conductivity, and the conductivity of Ag doping is the best.

Cohousing with Dirty Mice Increases the Frequency of Memory T Cells and Has Variable Effects on Intracellular Bacterial Infection
Authors: Labuda Jasmine C , Fong Kevin D , McSorley Stephen J
Published: February 2022

The presence of memory lymphocytes in nonlymphoid tissues reflects prior immunological experience and can provide nonspecific defense against infection. In this study, we used a mouse cohousing approach to examine the effect of prior immunological experience on Salmonella and Chlamydia infection. As expected, cohousing of “dirty mice” with specific pathogen–free laboratory mice increased the frequency of effector memory T cells in laboratory mice and enhanced protection against systemic Listeria infection. In contrast, the course of systemic infection with Salmonella and mucosal infection with Chlamydia was largely unaffected by cohousing, despite enhanced frequencies of memory T cells. Thus, cohousing of laboratory mice reliably increases the proportion of memory T cells in circulation, but can it have variable effects on pathogen clearance.

The aim of this study was to determine the technological properties of sorghum and millet malt produced under controlled conditions in Burkina Faso. Two types of steeping were carried out: steeping at normal pH (6.5) and at alkaline pH (8). Analyzes of the functional properties (diastatic power, alpha and beta amylase activity) of the samples of malts produced were carried out using Bernfeld modified methods. From the results, it appeared that the values of diastatic power, alpha and beta amylase and amylase activity increased significantly during the malting process (p˂0.001). The highest values for the diastatic power of the malts were obtained with millet malt (378.86 UPD and 336.45 UPD respectively for normal steeping and alkaline steeping). As for the diastatic power of sorghum malts, it varied from 79.14 UPD to 266.17 UPD. A negative correlation emerged between the diastatic power and the pH (R = -0.88), it also emerged that the diastatic power was much more correlated with the activity of alpha amylase (R = 0.99) than that of beta amylase (R = 0.6). Overall, the different types of malts exhibited satisfactory diastatic power and functional properties in accordance with standards for cereal malt production. These malts could therefore be used for the production of infant porridge in order to increase the energy density of porridge and also used in bread making to replace commercial enzymes often not appreciated by consumers.

Dans chacun des rectangles, tous les individus ligneux de diamètre à hauteur de poitrine (DHP) supérieur ou égale à 10 cm ont été identifiés, comptés et mesurés. Ces Relevés de surfaces couplés aux inventaires itinérants ont permis d’inventorier 167 espèces rangées dans 134 genres que se partagent 47 familles. Les familles les plus importantes dans l’ordre étaient : les Fabaceae, les Euphorbiaceae et les Malvaceae. Les Mésophanerophytes et les mégaphanerophytes étaient dominants avec les pourcentages respectifs de 43% et 35%. L’endozochorie était le mode de dissémination le plus rependu avec un taux de 79%. 14% des espèces recensées dans cette forêt étaient des espèces à statut particulier. Les valeurs moyennes des densités et aires basales des différents biotopes n’étaient pas statistiquement différents, qui indiquent une bonne conservation de la forêt. Ces résultats étaient donc suffisants pour justifier sa protection.

De las declaraciones a la garantía multinivel de los derechos sociales fundamentales: la aportación de Georges Gurvitch
Authors: Monereo Pérez José Luis
Published: February 2022

Georges Gurvitch (1894-1965) es uno de los fundadores de la sociología del Derecho en Europa y, desde luego, del Derecho Social tal y como hoy lo conocemos, aunque es necesario destacar también su condición eminente de filósofo y jurista interdisciplinar. Hay que llamar la atención sobre el dato histórico innegable de que su concepción de los derechos sociales se reflejó en diversas obras y en particular en su propuesta de La Déclaration des Droits Sociaux (1944), tuvieron una influencia extraordinaria en diversos instrumentos internacionales como la Declaración de los Derechos Humanos de 1948, el Pacto de Derechos Económicos, Sociales y Culturales de 1966, la Carta Social Europea (tanto en la versión originaria de 18 de octubre de 1961 como en la versión revisada de 1996), la Carta de los Derechos Sociales Fundamentales de los Trabajadores de 1989 (Declaración de Política del Derecho), y la Carta de los Derechos Fundamentales de la Unión Europea (versión originaria el 18 de diciembre de 2000 como Declaración de Política del Derecho, y la versión definitiva de 2007 con rango específico de Tratado de la Unión Europea, conforme a lo establecido en el art. 6.1 del Tratado de la Unión Europea, en redacción dada ya en su momento por el Tratado de Lisboa). Esa influencia se hace extensible a su magistral obra mayor en el campo fundante de la Idea Social y del propio Derecho Social, a saber: La Idea del derecho social (1932).
salario mínimo interprofesional en España y la Carta Social Europea: el desacuerdo permanente
Authors: Burriel Rodríguez-Diosdado Pepa
Published: February 2022

En España la entrada del euro como moneda supuso una pérdida de poder adquisitivo de los trabajadores con salarios más bajos y, asimismo, los salarios medios no han alcanzado los niveles previos a la crisis de 2008. Ahora, inmersos en una pandemia mundial, la COVID-19, con impactos socioeconómicos significativos, el gobierno de nuestro país retoma el art. 4 de la Carta Social europea que establece el derecho de las personas trabajadoras a una remuneración equitativa que les permita a ellas y a sus familias obtener un nivel de vida digno. Este Tratado internacional es la herramienta más eficaz para el establecimiento de un salario mínimo interprofesional adecuado a cada país, algo que ha formado parte del olvido de nuestros gobernantes en los años previos, pese a la insistencia del Comité de Derechos sociales que dictaminaba el incumplimiento de la Carta por parte de España. En el presente trabajo se analiza y profundiza en el concepto de salario mínimo interprofesional desde la óptica del derecho español, su evolución y su futuro para comprobar el grado de cumplimiento de la Carta social europea y la consecución de un nivel de vida digno para las personas trabajadoras.

L’épopée de Manas est l’un des plus illustres représentants du genre épique en Asie centrale. Ses impressionnantes dimensions et sa vigueur en font un objet d’étude de choix pour de nombreux chercheurs. Le principal objectif de cet article est d’analyser certains aspects de la géographie épique manassienne et d’observer leur évolution au cours du temps. Le texte épique n’est en effet pas fixe ou statique, mais évolue en fonction d’un contexte particulier (historique, culturel, social), contexte qu’il adopte et adapte suivant les forces en présence. Le texte épique ne peut s’interpréter et se lire qu’en regard du contexte dans lequel il a été produit. Cet article s’interrogera sur le thème de la migration et de son éventuelle trace dans le texte, et montrera que l’épopée agit comme une matrice pour réfléchir un contexte ethnique et politique régional changeant. Un exemple concret, enfin, analysera les dissensions qui peuvent exister entre Chine et Kirghizstan au sujet du texte épique.

The short story “Kappa” (1927), by the Japanese writer Ryûnosuke Akutagawa (1892-1927), revolves around the story of a man known only as patient number 23, an inmate at the S. insane asylum, who tells that he lived a season in the land of the kappas (half humanoid and half amphibians, from Japanese mythology) and describes their way of life in comparison with that of Japanese society. The anthropological movement of making the strange world of the kappas familiar and, in turn, making the human world exotic, runs through the entire tale. The aim of this work, therefore, is to explore the idea of the kappa myth as an ethnographic report, analyzing, from an anthropological perspective, the imaginary journey (or not?) of the protagonist, psychiatric patient number 23, into the world of these mythological beings.

The aim. Demonstrate a novel modality of laser-scanning multiphoton microscopy suitable for rapid acquisition of images of samples labelled with phosphorescent materials characterised by long emission lifetime measured in microseconds. The reported microscopy represents an advancement over the existing laser-scanning modalities, where the acquisition of images of phosphorescent materials takes unpractically long time.Materials and methods. The reported method is based on rapid scanning of the focussed excitation beam across a sample while continuously recording the photoluminescent (PL) signal. The resultant images of discrete phosphorescent nanoparticles appeared blurred. The diffraction-limited image was reconstructed by using a deconvolution algorithm, where the PL lifetime was the key input parameter. To test the method, two types of upconversion nanoparticles (UCNP) were synthesised, NaYF4:Yb3+:Er3+/NaYF4 (E-UCNP), β-NaYF4:Yb3+, Tm3+/NaYF4 (T-UCNP) and used to test a possibility of demultiplexing the two types of UCNPs ex vivo taken up in the mouse liver.Results. The resultant images of E-UCNP, T-UCNP on the background of the liver were fully reconstructed and exhibited the enhanced signal-to-noise ratio. Besides, the method allowed rapid (at the scale of seconds) acquisition of the UCNP PL lifetime and clear discrimination of the two types of UCNPs.Conclusion. We demonstrated a new approach for rapid PL image acquisition of samples containing PL materials, such as biological specimens labelled with discrete UCNPs. Blurred images were shown to be reconstructed at the post-processing stage by applying a deconvolution procedure. This enabled demonstration of multiplexing/demultiplexing using lifetime imaging mode, where the lifetime was engineered by the UCNP synthesis and reconstructed during multiphoton image acquisition using the deconvolution algorithm. The power of this method was demonstrated by the identification of two types of UCNPs accumulated in the liver of a laboratory animal. We believe that the demonstrated method can be useful for rapid lifetime imaging where several molecular specific labelling agents are required.
A Higher-Level Synthesis Tool for Rapid-Prototyping of Verilog RTL Designs from FSMD Specifications
Authors: Papoutsakis Stelios , Mansouri Nazanin
Published: February 2022

This work presents a light-weight synthesis tool, F2VGen (Finite State Machine to Verilog Generator), that generates Register Transfer Level (RTL) implementations modeled using Verilog hardware description language (HDL) from abstract specifications provided as extended finite state machines (FSMD). This approach takes synthesis yet to a higher level. In contrast to conventional high-level synthesis (HLS) where the design specification is given in behavioral Verilog, in this work specification begins at an even higher level of abstraction and is provided as a finite state machine that captures the data-flow. Designers can input the design specification using a graphical interface (GUI). The resulting synthesized design is implemented at the register-transfer level and is distinctly divided into a data-path (that performs the computations) and a controller (that controls the operation of the data-path). The process does not guarantee an optimized implementation in terms of area, power consumption or speed. However, it realizes the required functionality in hardware, and can be used in many settings where access to a fast prototype is required. The prototypes are implemented in reconfigurable devices such as Field Programmable Gate Arrays (FPGAs) and present an effective solution when a fast proof of concept design is needed, and also as a stand-in model in situations when testing the interactive systems in actual hardware is required.
