Who navigates the “elite” of communication journals? The participation of BRICS universities in top-ranked publications
Authors: Comel Naiza , Marques Francisco Paulo Jamil , Prendin Costa Luiz Otávio , Kohls Chirlei , Orso Maíra
Published: December 2023

Purpose

Despite the increasing volume of research addressing the relevance of de-Westernizing Media Studies, we lack a comparative evaluation of the performance of Global South universities regarding their presence in the most prestigious domains within the field of Communication. Against this background, the article explores if and to what extent the publication of articles authored by BRICS-based scholars in top-ranked journals is restricted to a handful of academic institutions – making them a national “elite” authorized to engage in the mainstream intellectual debate.

Design/methodology/approach

We pose three questions: RQ1) To what extent is the academic output of BRICS countries in the field of Communication concentrated within a select few “top-level” institutions? RQ2) How are the research articles from the most productive universities distributed across the journal rankings comprising the SJR database? RQ3) What partnerships do institutions from BRICS countries engage in when producing research articles? Using data from the SciVal (Elsevier) and SJR (SCImago Journal Rank) platforms, the empirical study encompasses a set of articles published between 2012 and 2021.

Findings

Our findings reveal that South Africa, Russia, and Brazil had the highest concentration of academic production within a select few universities. The disparities among the most and least productive universities can be attributed to a lack of ambitious policies in terms of academic innovation. The contrast becomes more evident when we consider China’s performance – which has implemented a range of strategies to foster international partnerships with Western academic communities.

Practical implications/social implications

We contend that the demand for “de-Westernization” must go beyond a mere plea for increased numerical representation. The exclusion of perspectives or phenomena from developing regions hinders the progress of knowledge production itself. Once Social and Human Sciences traditionally occupy a peripheral position in terms of funding, it is as if Communication researchers based in the Global South were part of a “periphery of the periphery.”

Originality/value

The paper is relevant for enabling us to discuss Global South universities’ international insertion and the dynamics influencing the academic contributions of semi-peripheral communities. We also consider to what extent the SciVal and SJR metrics reinforce an academic rationale that upholds the mechanisms of neoliberal globalization and the standardization of the scholarly agenda.

The complexation between fumaric acid (FA) and 1-phenylpiperazine (1 PP) is a fruitful cooperation that allowed the preparation of a new organic crystal entitled (4-phenylpiperazin-1-ium) hydrogenfumarate denoted by 4PPHFUM, which is reported in the present manuscript. This new substance is created by the slow evaporation that occurs when 1-phenylpiperazine and fumaric acid are combined in a stoichiometric 1:1 ratio. The stacking of the crystal is provided by O–H⋯O, N–H⋯O and C–H⋯O hydrogen bonds, also supported by C–H⋯π interactions between the organic cations. The importance of these interactions in the formation of this new crystal is confirmed by the Hirshfeld surface analysis which showed that H-bonds and supramolecular C–H⋯π interactions account for about half of the non-covalent interactions existing in this compound. These non-covalent bonds that encompass the synthesis and design of this supramolecule have also been analyzed in detail using a quantum chemical computational study. Using the docking – based drug design strategy, we investigated the therapeutic effect of this cooperative outcome between fumaric acid and 1-phenylpiperazine to demonstrate the improved therapeutic property of this novel non-covalent compound as a tyrosinase inhibitor. 4PPHFUM was found to be a potent tyrosinase inhibitor with high interaction energy with its protein, higher than that of the most potent tyrosinase inhibitors (thiamidol, hydroquinone, resorcinol, hexylresorcinol and kojic acid).

Authors: Callai Jaeme Luiz
Published: December 2023

En la dinámica del proceso de atracción de inmigrantes europeos, al final del siglo XIX, se construyeron en Brasil diferentes experiencias de implantación de núcleos de poblamiento, denominados localmente, “colonias”. En estas “colonias” familias de origen europeo pasan a la condición de pequeños productores rurales en contacto con la sociedad local constituida de luso-brasileiros, afrodescendientes e indígenas.El texto discute cómo la diversidad de estos grupos étnico-nacionales europeos, en el contacto con la sociedad envolvente, organiza y reorganiza una nueva identidad. Ahora no más de “europeos” pero de brasileños portadores de una cultura diferenciada con especificidades resultantes de esta particular experiencia histórico social.  Se considera aún la actuación educativa del museo local en este proceso de construcción identitaria.

Based on the results of theoretical, computational and experimental studies, the influence of the design features of glass unit (the number of chambers in a glass unit, the thickness of the glass, the ratio of the width of the glass unit to its height, etc.) on the intensity of convection and radiation heat transfer through translucent structures was determined. The dependence on the thickness of the gas layer of the structure of the free convection flow between the inner and outer glass of a single-chamber double-glazed window was determined. The dependence of the thermal insulation characteristics of windows on the physical properties of the gaseous medium (density, thermal conductivity, viscosity) located in the interlayer between the glasses was studied. The dependence of the intensity of radiation-convection heat transfer through translucent structures on the characteristics of the low-emission coating on the inner surfaces of the translucent part of the window was found. It has been shown that a glass unit without a low-emission coatings transfer most of the heat by radiation. Therefore, this low-e coating significantly increases the heat transfer resistance of windows. A thermophysical calculation model was developed to determine the effect of solar radiation on the thermal regime of translucent structures. Using it, the volumes of heat entering the room with solar radiation through translucent structures in the winter season were determined. The influence of heat fluxes from the ends on the temperature state of the adjacent window structures and walls was determined. The dependence of the operational characteristics and energy efficiency of the enclosing structure on the location of the translucent structure in relation to the window opening was established. The effect of the window frame profile configuration on the resistance of a translucent structure has been studied. The value of the heat transfer resistance of various window structures in the real conditions of their operation was experimentally determined. Experimental and numerical studies of heat transfer processes through energy-active windows, namely supply air’ ventilated and heated windows, have been carried out. Energy-active windows can be used as a backup heating system for the premises of the building, as well as to create a comfortable temperature and humidity regime in the room. Based on the results of theoretical and experimental research, recommendations were formulated regarding the main methods of increasing the energy efficiency of translucent enclosing structures and the walls adjacent to them.

Published: December 2023

The article examines the research of scientists on the development of a new industrial policy and analyzes papers devoted to assessing financial and economic incentives for the development of new technologies, innovations, smart industry and Industry 4.0. The intervention of state industrial policy in cases where the market fails to allocate resources effectively is analyzed, and the relevance of industrial policy is substantiated by economists and political leaders of the leading countries of the world. The theoretical foundations of the state innovation policy are defined, which is the link between the policy of scientific and technological progress and industrial policy aimed at developing principles for supporting the bringing of ideas and innovations to the market. It has been established that the widely used traditional instruments of innovation policy are government support for research organizations, primarily state universities and scientific institutes. Other common tools for financial and economic stimulation of industry are competitive funding of research (both fundamental and applied), fiscal preferences (tax incentives and subsidies) for R&D by industrial enterprises, and government support for technology transfer. Foreign studies of the theoretical aspects of financial and economic stimulation of development are systematized and grouped into the following areas: justification of state support for research organizations and competitive financing of scientific projects, assessment of the effectiveness of the use of fiscal preferences for R&D, analysis of the impact of state support in the process of technology transfer for the development of smart industry and stimulating the development and commercialization of innovations (patent box mode). An example is given of one of the areas of modern research into financial support for stimulating a particular industry – fiscal preferences for the production and sales of electric vehicles and charging stations. It has been established that financial and economic incentives for the development of new technologies and their implementation in the smart industry have a positive impact on the development of start-ups, innovation activities, the development of new products, an increase in the number of patents, additional output volumes, growth in investment and employment. It would be advisable to focus further research on analyzing the experience of foreign countries in stimulating the development of smart industry with the help of financial instruments (including fiscal instruments).
The nature of the psyche and consciousness, quantum computers and information models in psychoinformatics (socionics)
Authors:   International Institute of Socionics, Ukraine, A Bukalov
Published: December 2023

Modeling the psyche, consciousness and artificial intelligence have encountered conceptual difficulties in understanding real mental processes. Numerous modern studies and experiments presented in the review indicate the probable quantum nature of the psyche and consciousness. The analysis shows that a number of quantum processes are associated with known classical processes and structures, from a single cell to the brain. Therefore, adequate modeling of mental processes, including consciousness and intelligence, is possible only on multiprocessor quantum computers with a special architecture corresponding to the real structure of the psyche. This possible architecture is proposed by the theory of information metabolism - socionics (psychoinformatics), in which detailed holistic information models of the psyche have been developed, which have been used in practice for more than 30 years and have proven their effectiveness. These models represent a system of mental functions of information metabolism, which can be simulated by special quantum processors interacting with each other according to certain laws

A method has been developed in which atomic sizes misfit and elastic modulus misfit at crystal lattice nodes are considered as discrete random variables and the definition of their dispersion allows to obtain analytical expressions for standard deviations and correlation lengths of the short- and long-wave components of stochastic shear stress field created by solute atoms in the glide plane in a multicomponent alloy. This makes it possible to significantly reduce the amount of calculations when determining the shear stress field parameters. The developed method was applied to calculate these parameters for the CrCoNiFeMn alloy. The calculated parameters were well correlated with similar parameters determined from the analysis of shear stress distributions in the glide plane, which were calculated by the method of direct summation of solute atoms contributions. In addition, it was found that there are separate effective crystal lattice distortions for the short- and long-wave components that differ from the average distortion that was proposed earlier. This results from the fact that these components are determined by solute atoms with different distance from the glide plane. Effective distortion is greater, the greater this distance from the glide plane. In addition, there is no single empirical constant for all alloy to determine the yield strength as a function of their shear modulus and average distortion. But the proposed method makes it possible to determine the main parameters of the shear stress field in a specific multicomponent alloy. These parameters can be used to calculate the yield strength of this alloy. Keywords: shear stress, multicomponent alloy, glide plane, solid solution.

The deformation process of powder materials thin-walled bushings manufacture was investigated by computer modeling. Two shape formation bushings schemeswere considered (direct extrusion and radial compaction).A continuum approach was used to create a modeling method. The method is based on rheological models of porous body plastic deformation and the finite element method. The accepted material rheological model allows describing the deformation of both powder and porous blanks. It takes into account the different resistance of these materials in tension and compression. Modeling of the deformation process was carried out in stages, using the method of successive loads. The elastic stresses were determined, the plastic potential was calculated and, if it was necessary, the stresses and material parameters of the model were corrected at each load step. The porosity value is reach maximum in blank and area, that is free from the loads, and the accumulated deformation is reachminimum in direct extrusion. The effect of back pressure leads to a more uniform distribution of these parameters, a decrease in porosity and an increase in the accumulated deformation of the solid phase. During radial compaction of thin-walled bushings, deformation of the material occurs locally. Porosity in the product section increases with increasing radius. Increasing the number of technological transitions with a gradual increase in the forming tool diameter reduces the uneven distribution of residual porosity and its value. However, the unevenness of the porosity distribution over the radius remains. In the process of radial compaction, a burr is formed on the ends of the product. The burr can be reduced by changing the initial shape of the blank. The process of direct extrusion allows obtaining more uniform distribution of residual porosity and accumulated plastic deformation of product material. However, this technological process requires the higher loads application, which leads to less stability of the tool. The radial compaction method (which characterized by local deformation) requires not high loads and allows not powerful equipment using. However, the distribution of residual porosity over the radius of the bushing is uneven. Keywords: plasticity theory, powder materials, computer modeling, finite element method, stress-strain state, porosity distribution.

Zinc oxide is a wide-gap semiconductor with unique properties, used for the manufacture of catalysts, electrodes, transistors, etc. In these applications, there is a need for metallization and joining of ZnO-based materials, using of molten metal filler is an effective method. Contact of zinc oxide and liquid metals is almost not studied in comparison to other oxide materials. In this work the wetting of zinc oxide based ceramic with metal melts of the silver-copper system in high vacuum was studied. Alloys with concentration of copper (% (at.)) 0 (pure silver), 5, 10, 20, 30, 39, 100 (pure copper) were used. Increasing the concentration of copper in the silver-copper melts significantly improves the wetting of ZnO-ceramic with these liquids, the contact angles decrease from 137° for the pure silver to 28° for the pure copper. Investigations of the microstructure show presence of relatively thin transition layers on the interfaces for silver-copper alloys, for the pure copper case the interface has complex “island-like” microstructure. Also a ruination of ZnO-ceramic substrates due to an interaction with metal melt was noted, the higher copper concentration, the more intensive ruination. Also some signs of the presence of zinc in the metal drops solidified on the zinc oxide surface were revealed, such as, intensive oxidation of the drops in air at room temperature. The oxidation shows complex multiphase microstructure of the solidified drops. After wetting of the zinc oxide with pure copper the solidified metal has microstructure of brass (Cu—Zn alloy) with low zinc concentration. The effects observed can be explained by sublimation of the zinc oxide under experimental conditions (high temperatures, vacuum) with formation of gaseous products (oxygen and vapor of zinc), which subsequently dissolve in silver-copper liquid drops. In particular, the dissolution of oxygen in the Ag—Cu melt improves its wetting of surfaces of solid oxides and presence of zinc in solidified drops provides its oxidization in air. Keywords: zinc oxide, wetting with metals, contact interaction, microstructure, transition layer.

Semiconductor oxide materials such as gallium, indium and zinc oxides play an important role in a development and production of a variety of electronic devices. Experimental studies of these materials allow to define, for example energetic or other physical parameters of the devices created and also to improve existing technologies of their production, metallization and joining of electrocontacts by way of brazing which require additional wetting studies. It should be noted that data on wetting of mentioned oxides by metals are practically absent in literature. Thus a detailed experimental study of the interfacial interaction, adhesion and wetting of Ga2O3, In2O3 and ZnO oxide materials with some pure metal melts (Ga, In, Sn, Au,Ge, Ag, Cu) in vacuum was performed by the sessile drop method using photo- and video- fixing including temporal and temperature dependencies of contact angles. It was found that pure metals don't wet powdery pressed specimens of Ga and In oxides in the temperature range studied and vary in a rather narrow range. For ZnO system the significant effect of experiment temperature and hold-up time on the values of contact angles for some metals (Ga, Ge, Sn, Cu) is observed. For example wetting angles for Ga change from above 90 degrees at low temperatures up to 49 and full spreading at 1173⎯1373 K. This effect may be attributed to the activation of chemical reactions, change of oxide stabilities at high temperatures at the interface. Last metals can be used as adhesive-active additions to base brazing alloy. Keywords: gallium, indium, zinc oxides, semiconductor, wetting, contact interaction, metal melt.

RESUMO Objetivo: Descrever a evolução espaço-temporal das taxas de incidência (TIs) de tuberculose (TB) em indígenas e não indígenas, segundo as unidades federativas do Brasil, no período de 2011 a 2022. Métodos: Estudo ecológico, temporal e espacial sobre os casos novos de tuberculose no Brasil em indígenas e não indígenas. Dados provenientes do Sistema de Informação de Agravos de Notificação (SINAN) foram coletados de 2011 a 2022 e estratificados por UF, analisados exploratória e estatisticamente por meio do software R 4.2.3. Resultados: A TI média entre indígenas no Brasil foi 71,7 casos novos para cada 100 mil habitantes, enquanto para não indígenas foi de 28,6/100 mil habitantes. As regiões do país que apresentaram as maiores incidências (médias) para indígenas foram: Centro-Oeste (102,8/100 mil hab.), Sudeste (99,6/100 mil hab.) e Norte (79,9/100 mil hab.), e para não indígenas foram: Norte (36,5/100 mil hab.), Sudeste (31,3/100 mil hab.) e Nordeste (27,4/100 mil hab.). A análise mostrou que a maior incidência de casos de TB nas populações indígenas ocorreu nos estados de São Paulo, Rondônia, Rio de Janeiro, Mato Grosso do Sul, Mato Grosso e Pará. Conclusão: Altas incidências da doença em comparação com a população não indígena mostraram a necessidade de abordagem específica para atender às necessidades de saúde dessas populações. As disparidades regionais nas incidências indicaram a necessidade de abordar questões socioeconômicas e de infraestrutura que afetam a saúde desses povos.

Entre peinture et musique : la répétition chez Clarice Lispector
Authors: Gama Carolina Antonaci
Published: December 2023

Résumé Étant donné que l’œuvre de l’écrivaine Clarice Lispector est composée par des fragments de textes publiés un peu partout : ses romans sont construits à partir des extraits des récits, les récits sont des rééditions des chroniques de journal, les chroniques de journal forment un autre roman, etc., nous tenterons de démontrer avec cet article qu’une telle répétition, l’insistance à répéter les mêmes paroles, les mêmes idées, les mêmes personnages, finit par créer un style littéraire unique qui nous contraint, à force de répéter, à déciller les yeux et voir. Avec la répétition, nous parvenons à voir ce qui est toujours là, ce qui est toujours donné, évident, quotidien. Et puisque la répétition est mal acceptée en littérature, comme le souligne d’ailleurs Hélène Cixous, nous verrons que Lispector s’en sert de la peinture et de la musique pour soutenir son œuvre « répétitive » et nous dévoiler que la répétition littéraire, entre la peinture et la musique, peut fait émerger la chose « vraie » et nous conduire vers la préhistoire d’un futur.
Entre modernismos e descolonialidades: desafios para uma teorização outra
Authors: Nolasco Edgar Cézar
Published: December 2023

RESUMO A ideia basilar deste ensaio resume-se, grosso modo, em comparar uma perspectiva teórica modernista (moderna) com uma perspectiva de ordem descolonial ou fronteiriça. Considerando, a priori, que em tal relação de proposição pode haver aproximação que não seja exclusivamente de contrastes entre ambas as perspectivas, vamos procurar estabelecer uma discussão declinada em uma teorização de base descolonial ou fronteiriça que, a seu modo, além de pontuar suas diferenças em sua visada teórica, também pontue as especificidades de uma discussão teórica presa aos postulados de um olhar que priorize os modernismos. Para alcançar o cerne da discussão proposta aqui vamos nos valer, a princípio, de duas abordagens específicas, ou pontos de vistas teóricos diferentes entre si. Refiro-me aos textos “Teorizar é metaforizar”, de Eneida Maria de Souza, presente em seu recente livro Narrativas impuras (2021), e “Desafios decoloniais hoje” (2017), de Walter Mignolo. Além desses dois textos, será de valia para a proposta o livro Fisiologia da composição (2020), de Silviano Santiago, e meu texto intitulado “Podemos fazer teori(a)zação da fronteira-sul”, entre outros que se fizerem necessários no decorrer da reflexão aqui proposta.
GEOLOGÍA DE LA PASIÓN: EL RETORNO A LA CAVERNA DE G.H.
Authors: freire raúl rodríguez
Published: December 2023

RESUMEN La pasión según G.H. es uno de los textos más comentados por la crítica especializada. Al tratarse de un texto clásico, esto es, un libro posible de ser leído por cada nueva generación desde nuevas entradas, el presente trabajo intenta una lectura de la obra de Clarice Lispector a partir de algunos conceptos pertenecientes a la geología. En primer lugar, se mostrará la importancia del mediodía como marco de la metamorfosis por la que atraviesa G.H., dado que es el mediodía el instante que produce la caverna donde tendrá lugar su transformación. Luego se abordará la significancia del tiempo profundo y su relación con la destitución, leída aquí como desedimentación, de la figura humana. En este punto, se abordará también la inversión del mito de la caverna de Platón por parte de G.H., inversión que representa una crítica radical del pensamiento metafísico y su linealidad. Finalmente, la lectura realizada llevará hacia la pregunta por la materialidad sobre la que se escribe el propio libro, esculpido, como si fuera una escultura, por las propias manos de G.H.

Modern principles of treatment of Peyronie's disease
Authors: Zurnadzh'yants V. A. , Kurashov D. V. , Kchibekov E. A. , Proskurin A. A.
Published: December 2023

Fibroplastic induration of the penis, known as Peyronie's disease, remains one of the most difficult problems in medicine today. The prevalence of the disease among men ranges from 2.5 % to 9 % between the ages of 40 and 70 (statistics according to studies conducted by scientists in different countries). It is a benign, slowly progressive disease. It is characterized by the formation of idiopathic fibrous plaques in the albuginea of the penis. Peyronie's disease affects not only the organic part of a man's health, but also affects the psychological aspects of his activity, negatively affects the patient's professional activity and family life, which determines not only the medical, but also the social significance of the problem. The hypothesis of the occurrence of Peyronie's disease has received wide publicity as a result of a trauma to the penis, in which bleeding and delamination of the albuginea occur, and a neglected inflammatory process with disorganization of elastic fibers with collagen deposition heals with coarse scarring. Despite the fact that progress has been made in understanding the mechanisms of development of Peyronie's disease, the therapy of this disease remains one of the most complex and controversial. Analysis of literary sources shows that unsatisfactory results of surgical treatment are still at a high level.

Der industrielle und soziale Wandel zwingt die Berufsgenossenschaften zu Veränderungen, die sich sowohl auf neue Aufgaben als auch auf einen organisationalen Change zu konzentrieren haben. Dabei gerät die Gefährdungsbeurteilung psychischer Belastungen ins erweiterte Blickfeld des Arbeitsschutzes. Es ist bekannt, dass organisationale Change-Prozesse negative Auswirkungen auf die Gesundheit und psychische Befindlichkeit der Mitarbeitenden haben: Diese zu kennen und ihnen adäquat begegnen zu können, muss das Ziel wissenschaftlicher Expertise sein.

INFLUENCE OF NICKEL ON THE MICROSTRUCTURAL EVOLUTION AND MECHANICAL PROPERTIES OF LM6-ALLOY-BASED FUNCTIONALLY GRADED COMPOSITE TUBES

Published: December 2023

Despite the growing demand for new materials, we used the horizontal centrifugal casting technique to synthesize functionally graded composite (FGC) tubes using an LM6 alloy containing (3, 6 and 9) w/% nickel. All the fabricated tubes were evaluated for variations in microstructure, hardness and tensile properties along the radial cross-section in three distinct zones (inner, transition and outer). X-Ray diffraction (XRD) results indicated the formation of in-situ Al3Ni in all FGC tubes, and these in-situ tri-aluminides increased further with the addition of Ni. A comprehensive microstructural analysis across the tubes utilising scanning electron microscopy (SEM) images showed that gathering in-situ Al3Ni particles keeps growing nearer the outer zone, and primary Si cuboids increase in the inner zone. This accumulation of particles improved the mechanical properties at all three zones of the FGC tubes compared to the LM6 tube having no nickel. The results of the hardness investigation showed that precipitated Al3Ni in FGCs has a beneficial impact on the enhancement of hardness. Furthermore, the observed UTS improvement in the FGC tubes was clearly associated with the precipitation and strengthening action of Al3Ni intermetallic phases, while a significant reduction in elongation has been noted. Due to the influence of centrifugal force and density variation, the tube containing 9 w/% of Ni demonstrated good gradation among composite alloy-fabricated FGC tubes, with in-situ Al3Ni particles settling largely in the outer zone and primary Si particles settling primarily in the inner zone across the radial thickness.
INFLUENCE OF DOPING WITH CARBON AND NITROGEN ON THE PHOTOACTIVITY OF TiO2 THIN FILMS OBTAINED WITH MePIIID
Authors: Gjevori Altin , Ziberi Bashkim
Published: December 2023

Titanium dioxide is well known as a photoactive material activated under ultraviolet irradiation. It is either employed as a photocatalyst or it exhibits superhydrophilic behavior after obtaining reduced surface energy under illumination used for self-cleaning or anti-fogging surfaces. For increasing the reactivity of thin films under solar illumination, a reduced band gap is desired. Doping with transition metals or nitrogen has been reported in the literature. However, the incorporation of nitrogen into a growing film is a much more complex process that is presently not completely understood. TiO2 thin layers were produced by metal plasma immersion ion implantation and deposition at room temperature at a pulse voltage of 0–5 kV and a duty cycle of 9 % for an apparently amorphous layer. An auxiliary rf plasma source was employed to increase the growth rate at low gas flow ratios. By adjusting the geometry between the incident ion beam, sputter target and substrate independently of the primary ion energy and species, a controlled deposition of samples was possible. Conventional ion implantation was employed to implant either carbon or nitrogen ions below the surface for bandgap engineering. The resulting thin films were subsequently investigated for optical properties, stoichiometry, structural properties, surface topography and photoactivity.

Published: December 2023

We have studied the effects of different solution temperatures and holding times on the microstructure and room-temperature mechanical properties of the alloy using methods such as electron backscatter diffraction, hardness testing and tensile testing. The results showed that the average grain size increased significantly as the solution temperature increased, and many annealing twins appeared in the grains. The fraction of twin boundaries reached its maximum value at 1080 °C. The hardness, yield strength and tensile strength of the alloy decreased with an increase in the solution temperature, but abnormal yielding occurred at 1160 °C. The elongation after fracture and the area reduction increased with an increase in the solution temperature. The fracture morphology of the alloy was irregular, conical, accompanied by a large number of ductile dimples, and the material exhibited typical ductile fracture. At the same time, as the solution temperature increased, the number of dimples on the fracture surface continued to increase, the depth of the dimples gradually increased, and the distribution became more uniform.
OPTIMUM DESIGN OF A PERMANENT-MAGNET-BASED SELF-CHARGING DEVICE FOR A SMARTPHONE
Authors: Vishwakarma Anubhav , Komelj Matej
Published: December 2023

A smartphone battery can be charged without an external power source by applying a portable charger that transforms mechanical energy into electricity by means of magnetic induction. Its essential part is a permanent magnet made of a rather expensive and, from the point of view of availability as well ecology, problematic material. The magnet is usually assembled from cylindrical parts. In order to reduce the raw-material consumption and to simplify the production, we propose a single-piece design in the form of a cylinder with notches. By means of the finite-element modelling, we optimize the dimensional parameters and prove that our proposal is more efficient than standard solutions.
Mensaje urgente. Tulio Restrepo y la poesía visual como práctica política
Authors: De Gracia Silvio
Published: December 2023

En el presente conjunto de poemas, provenientes del libro titulado Vispoiesis, Pliegos de la visión n° 96 (2019), Restrepo se presenta como un operador visual que conjuga acabadamente la vocación experimental y conceptual. Encabalgado sobre preocupaciones políticas diversas, con cada una de sus piezas consigue persuadirnos de que es posible la práctica de una poesía visual que se imbrique profundamente con el contexto y que se arriesgue en un posicionamiento crítico, algo que se impone casi como una urgencia en una realidad que exige el compromiso de todo poeta y artista en la construcción de nuevos horizontes y sentidos.
Između individualnog i kolektivnog iskustva: Prvi svjetski rat u rumunjskom romanu
Authors: Olujić Ivana
Published: December 2023

World War I (1914 – 1918) spread across the majority of Europe and was the first conflict of such proportion in history. Its ending brought significant changes in economic relations on world level, leaving a lasting demographic effect, and – by enabling the creation of new countries – it changed the geographical map of the war-ravaged area. The trauma of war was reflected in the modern novel rather shortly after these events. Writing about war, especially while its memory is still fresh to the readers’ mind, holds great responsibility, bearable only by great writers. This is why three canonical novels of Romanian literature written in the first two decades following the war have been selected for closer reflection in this book: "Forest of the Hanged by Liviu Rebreanu" (1922), "The Dragon" by Hortensia Papadat-Bengescu (1923) and "The Last Night of Love, The First Night of War" by Camil Petrescu (1930). All three share the theme of World War I, but each of the three authors approaches it with different experiences, builds different structure and chooses different narrative techniques. Thus, the reader is offered three different perspectives of Romania and the war.

Published: December 2023

The study aimed to synthesize silver nanoparticles with anti-diabetic properties using Cassia fistula bark extract using a one-step biological method. The methanolic bark extract was mixed with a 1mm silver nitrate solution, and the resulting silver nanoparticles were characterized using various methods such as visual examination, UV visible spectroscopy, FTIR spectroscopy, Field Emission Scanning Electron Microscopy, in vitro Dissolution Study, Particle Size determination, and Zeta Potential determination. The green synthesis of silver nanoparticles using Cassia fistula bark extract aimed to develop a novel drug delivery system with herbal drugs to reduce side effects. The plasmon band in the silver nanoparticles was found to be 425 nm, and the FTIR study revealed a higher presence of Hydroxyl and carboxylic groups as reducing and stabilizing agents. The drug entrapment was found to be 61.5%, the particle size was 148.5 nm and the polydispersity index was 0.243. The zeta potential was measured to be -0.1 mV, indicating no stabilization of the silver nanoparticles. The FESEM analysis showed the synthesized silver nanoparticles to be spherical and oval in shape. This biological method is eco-friendly and cost-effective, making it a promising alternative to traditional chemical/stabilizing agents.
