Authors: Ochoa-Rico María-Salomé , Del Rio Juan Antonio Jimber , Sorhegui-Ortega Rafael , Vergara-Romero Arnaldo
Published: December 2024

This study examines the contentment and commitment of rural residents from three different perspectives. The first is environmental management, followed by municipal services and finally territorial planning. The study’s objective is to analyze the causal relationships between the expected quality and perceived quality concerning perceived value, satisfaction and citizen loyalty to provide tools for decision-making to public managers. This research proposes a structural equation model to evaluate and validate five hypotheses. For this study, household-level surveys were implemented to a population sample of 450 families in the rural area of Tenguel in Ecuador. The results suggest that the public policies exercised by territorial managers significantly influence citizens’ perceived value, satisfaction, and loyalty, which impacts social welfare. This research shows that there are deficient areas that negatively impact perceived locality, which decreases the perceived value. Such as firefighting service, municipal police, veterinary services, preservation of historical and cultural assets and activities, and facilities for community use.

Authors: Adrian-Marius Pascu , Olivia-Laura Petraşcu
Published: December 2024

This study evaluates the four-point flexural behavior of polyoxymethylene (POM) specimens exposed to different environmental conditions. Ten specimens were tested, for each of which five different mediums were studied: ambient environment, distilled water, cooling oil, UV-C radiation, and saline solution. The main objective was to find the influence of these environments on maximum bending stress and compare the values obtained for all four aggressive mediums to the value for the ambient environment. The results showed that exposure to the three liquid media-distilled water, cooling oil, and salt solution-leads to a reduction in bending stress, underscoring the potential weakening effects of these media. In contrast, samples exposed to UV-C showed an increase in bending stress, suggesting an increase in material stiffness under these conditions. This study provides guidelines for the optimal use of POM in various applications and provides clear information on its mechanical performance in various industrial and environmental environments.

A case of assisted reproductive technology–induced maternal alloimmunization: an emerging sensitizing factor to consider?
Authors: Sachan Deepti , Thiyagarajan Varnisha , G Deepthi Krishna
Published: December 2024

Red blood cell (RBC) alloimmunization can occur because of exposure to various sensitizing factors and poses a constant threat in transfusion. Assisted reproductive technology (ART) involves manipulation of sperm, ova, or embryos in vitro with the goal of producing a pregnancy. We present an interesting case of ART-induced maternal alloimmunization (AIMA) due to anti-c in a woman carrying a twin pregnancy. A 35-year-old primigravida, whose blood sample typed as group B, D+ and showed anti-c in her plasma, delivered twins by cesarean section. The spouse’s blood group was also B, D+. The blood groups of twins I and II were confirmed to be B, D+ and AB, D+, respectively. The RBCs of twin I were c+, but those of twin II and the spouse were c−. On enquiry, history of ART with donor sperm insemination was noted. Because there were no previous sensitizations, antigenic inheritance from the sperm donor to twin I could be the possible sensitizing factor for maternal alloimmunization. To the best of our knowledge, this case is the first report of ART-induced maternal RBC alloimmunization in the literature. History of ART exposures should be documented, and appropriate RBC phenotyping of the parent as well as potential ART donors will help in timely detection or prevention of hemolytic disease of the fetus and newborn or other AIMA-related complications.

Published: December 2024

Monitoring deformations in mining pillars in salt mines is crucial for detecting spalling, cracks, and distortions caused by internal pressures, with the aim of preventing mining accidents and maintaining structural integrity. At Salina Ocna Dej, annual measurements have not utilized drone technology, which was recently introduced in Romania. The measurements conducted with the DJI Phantom 4 Pro Plus drone in 2020 and 2024 provided essential data on changes in the mining pillar. In 2020, difficulties caused by air currents slightly affected the measurements, but by 2024, improved conditions allowed for more accurate results. The horizontal sections taken at various elevations revealed significant spalling and distortions, particularly on the eastern and western sides, with substantial rupture in the northwest corner and displacements on the northern side. Comparing the data from the two measurement sets showed a significant difference in precision, highlighting the need for regular inspections to prevent premature erosion and avoid accidents.

Published: December 2024

The work presented a facile, one-step procedure as a green assembly process for preparing silver tungstate nanorod by hydrothermal technique via a chemical reaction between silver nitrate and sodium tungstate. The synthesized precipitate was characterized using X-ray diffraction (XRD) transmission electronic microscope (TEM) and scanning electron microscopy (SEM) to ensure the formation of crystallization and single-phase material. The prepared nanorods undergo a catalytic evaluation to synthesize tetrahydrobenzo[a] xanthene-11-one derivatives by a one-pot reaction of β-naphthol, dimedone, and aromatic aldehyde with a catalytic amount of silver tungstate under the solvent-free condition at 60–70 °C. ArgC is one of the L-arginine biosynthetic pathways of mycobacterium tuberculosis. The molecular docking explains that all the synthesized compounds presented high ligand ability for the targeted enzyme compared with xanthene-9-carboxylic acid as a reference.
Effect of metal addition of Cu, Ni, and Fe on swelling Zeolit Alam Lampung (ZAL) to present amphoteric features on Cu-Ni-Fe/ZAL swelling
Authors: Susmanto Prahady , Intang Ambo , Bustan Muhammad Djoni , Haryati Sri
Published: December 2024

The main challenge in using Zeolit Alam Lampung (ZAL) as a catalyst lies in controlling its acidic nature which is influenced by the content of alkali metals, alkaline earth metals, transition metals, and Si/Al ratio. Controlling by reducing and adding metals with higher acidity is necessary. This research involved two stages: ZAL Swelling formation followed by adding Cu, Ni, and Fe metals to make a Cu-Ni-Fe/ZAL Swelling catalyst. The acid distribution analysis using the NH3-TPD profile test showed that the Cu-Ni-Fe/ZAL swelling catalyst exhibited higher Lewis-type acidity and more uniform distribution compared to Brønsted acid. The addition of Cu, Ni, and Fe metals can modify the acidity strength of ZAL Swelling to form Cu-Ni-Fe/ZAL Swelling catalysts with Lewis and Brønsted sites at lower temperatures (120–550 °C) compared to ZAL Swelling (120–750 °C). This gives an idea about the optimization of the arrangement of Lewis and Bronsted acid sites to present amphoteric features.

Published: December 2024

Fracture in a revolving tube due to creep deformation and thermal-mechanical fatigue is a growing concern in industrial equipment research and production, especially after long-term exposure to corrosion and high-temperature conditions in roasting furnaces. The calcination temperature and residence time are crucial in the catalyst production process, with optimal conditions en-hancing catalyst activity and stability. To improve the longevity of roasting furnaces, optimizing the construction structure of the calciner is critical. This study develops a novel calciner structure and mathematical models to understand the effect of structural parameters on critical performance. Computer simulations, predictive modelling, and rotational velocity analysis of the novel calciner were performed using a DEM. The effects of the baffle angle and overlap ratio on the flow pattern and MRT were studied through simulations and experiments. The main conclusions are as follows: (1) The operating parameter with the greatest effect on the MRT was the rotational angular velocity, followed by the baffle angle and overlap ratio. (2) The MRT calculation based on the numerical method model showed an error of no more than 10.0% compared to the actual measurement data, confirming the model’s accuracy. Our study provides a theoretical foundation for a deeper understanding of the complex MRT and flow field processes within this novel calciner. It also aids in optimizing the working parameters, performance, and structure of pilot equipment while offering fundamental data for future industrial applications.

Authors: Hang Xingping , Wu Xiaotian , Song Wei , Chen Shuai
Published: December 2024

In this study, graphite and copper from spent LIBs were used to prepare graphite supported zero-valent iron-copper (ZVI-Cu/G) by ball milling, to improve the reactivity of ZVI. The structure, composition, morphology, and properties of ZVI-Cu/G were fully analyzed. The removal performances of tetracycline by ZVI-Cu/G were tested under different reaction conditions. Graphite and copper improve the dispersion, specific surface area and reactivity of the material. Operational factors, material dosage of 1 g/L, initial pH of 3, temperature of 25 °C, and H2O2 concentration of 2 mM, contribute to the best tetracycline removal rate, being 100% in 30 min for 30 mg/L tetracycline solution. The reaction data fits a pseudo first-order model. Tetracycline removal rate was as high as 90% even in the 3rd round of reuse. This study reports a novel ZVI material with high tetracycline removal rate.
Factors Affecting the Phase Inversion Process of Alkyl polyglycol ether C16-18/Fatty Alcohol/Oil/Water System
Authors: Zhang Wanping , Cui Dingyuan , Zhang Qianjie , Zhang Dongmei , Zhu Guangyong
Published: December 2024

The change of spontaneous curvature of nonionic surfactants is related to temperature. The phase inversion of the emulsion system is induced by temperature change, which is called phase inversion temperature method. Experiments were carried out in which Ceteareth-12 (Alkyl polyglycol ether C16-18) and Ceteareth-20 (Alkyl polyglycol ether C16-18) were used as hydrophilic emulsifiers and fatty alcohol as lipophilic emulsifiers. It was found that the increase of HLB value of hydrophilic emulsifier, the decrease of fatty alcohol content or the increase of carbon atom number of fatty alcohol led to the increase of phase inversion temperature of the system. The experimental results also showed that when the hydrophilicity of emulsifier system was enhanced, the second phase inversion would be more obvious. The phase inversion temperature of ester oils is generally higher than that of alkane oils.

Published: December 2024

The aim of this study was to characterize the bioactive components in avocado oil (AVO) extracted by ultrasound combined with microwave, which are clean technologies used to assess oil quality. AVO samples were incubated for 30 min at 120 °C (T1), 180 °C (T2), and without any heat treatment (T3). Components were identified using chromatographic techniques, Raman spectroscopy, and thermogravimetric analysis (TGA). γ-Tocopherol and total carotenoids were affected in T2. The Raman spectrum of T3 and T1 presented a strong band at 1265 cm–1 related to the high content of linoleic acid and three bands associated with carotenoids. In the T2 sample, a weak intensity of the linolenic and linoleic acids was observed. In TGA, T2 showed a robust mass at 173.89 °C, characteristic of oxidized oil compounds. AVO treated at 120 °C for 30 min maintained the integrity of the bioactive compounds.

Authors: Veigners Girts , Galins Ainars , Dukulis Ilmars , Veignere Elizabete
Published: December 2024

The increasing reliance on renewable energy sources such as solar and wind power necessitates the development of advanced forecasting techniques to address the inherent variability and unpredictability of these energy systems. Accurate forecasting is vital for optimising energy production, maintaining grid stability, and effectively integrating renewable energy into power systems. Traditional forecasting methods often struggle to adapt to rapidly changing environmental conditions and new data inputs, limiting their effectiveness in dynamic contexts. This study introduces the Self-Improvement Cycle (SIC) module, which is designed to enhance forecasting accuracy through continuous learning, adaptation, and feedback integration. The SIC module leverages advanced machine learning algorithms, reinforcement learning techniques, and reflective practice principles to create a self-improving framework that dynamically updates models based on real-time data and external feedback. The module’s design incorporates multiple feedback loops, enabling the system to iteratively refine its performance and remain robust in the face of changing conditions. Reflective practice, a concept drawn from psychology, plays a critical role in the SIC module by facilitating ongoing evaluation and adaptation. By learning from previous predictions and continuously adjusting algorithms, the SIC module demonstrates its potential to improve forecasting accuracy across various domains, with a particular emphasis on renewable energy forecasting. The theoretical and mathematical foundations of the SIC module are explored, showcasing its capability to enhance predictive accuracy and resilience in an evolving energy landscape.

Published: December 2024

The paper discusses the impact of recent socio-economic and geopolitical changes on cultural ties and ethnic identity formation in the wider area of Čabar, Croatia. It emphasises the importance of understanding the historical context of cross-border relations in this geographically peripheral border region. To assess the specific position of relative isolation, a robust interdis- ciplinary methodological approach was used, combining the analysis of historical documents, registry books, and population censuses with qualitative methodology like in-depth semistructured interviews with local residents. To assess the specific local interrelations, the patterns of population migration and cross-border marriages (presented in the appendix) were reconstructed and exa-mined. Changes that occurred after the dissolution of Yugoslavia and the establishment of new independent states shed new light on how the local populace reproduced their identity.

Allelopathic potential of Asystasia gangetica: A study on growth and production of sweet corn
Authors: Yaqin Roelly Ainul , Santosa Edi , Guntoro Dwi
Published: December 2024

Coromandel, or Chinese violet (Asystasia gangetica), is an invasive weed on many plantations in Indonesia, especially oil palm plantations. The A. gangetica is suspected to produce allelopathic compounds. However, the evaluation of the effect of A. gangetica on plant growth is still rare. The research objective was to evaluate the effect of allelopathic compounds of A. gangetica on the growth and production of sweet corn as a test plant. An experiment with a randomized complete block design and four replications was conducted from March to September 2022 at the Agribusiness and Technology Farm IPB. The treatment was the A. gangetica population consisted of 0 (control), 1, 2, 4, 8, and 16 individuals per pot. A. gangetica were initially planted from seeds, and the stems were slashed 5 cm above the soil surface two months after planting. One week after cutting, sweet corn seeds were planted and maintained until harvest 72 days after planting. The results showed that the allelopathic effect of A. gangetica was evident in growth of sweet corn plant. Increasing number of A. gangetica per pot increased the allelopathic effect. The most significant effect was from 16 populations per pot, which significantly reduced the growth of sweet corn height, stem diameter, leaf size (length and width), leaf number, and color. The particular population per pot also decreased sweet corn yield, i.e., weight per cob with and without husk, and cob diameter by 18.95%, 22.0%, and 19.37%, respectively. The level of sweetness decreased by 31.24% after sweet corn was planted in the remnant of 16 individuals A. gangetica per pot. Nevertheless, A. gangetica did not significantly affect leaf area index, cob length, and sweet corn biomass, including shoot and root dry weight at harvest. It would be interesting to evaluate the effect of A. gangetica in the field.

The composition of fat in the body can show the balance between intake and use of nutrients in the body. If the body has more nutritional intake than it uses, then the excess nutrients (carbohydrates and protein) will be stored in the form of reserve fat in the body. Continuous accumulation of reserve fat without sufficient physical activity can cause weight gain and obesity. Obesity can trigger cardiovascular disease, metabolic syndrome, diabetes, dyslipidemia, and others. This research was conducted to determine the characteristics of body fat percentage and its distribution in Udayana University medical students in 2023. This research used a cross-sectional observational design. The respondents of this research were medical students in the class of 2020–2022 at Udayana University who met the inclusion and exclusion criteria. The sampling technique uses proportional random sampling with a minimum sample size calculated using the Slovin formula. From 105 research respondents, it was found that 49.5% of them had normal body fat percentage. In male respondents, the proportion of body fat percentage was almost the same in the normal (42.9%) and high (40.5%) groups. In female respondents, the proportion of body fat percentage was quite large in the normal (55.6%) and low (22.2%) groups. Most of the respondents had normal waist circumference (74.3%) and normal waist-to-hip ratio (68.6%).

Hal tersebut diduga menjadi penyebab mayoritas siswa memiliki tingkat pengetahuan baik.
Límites a la articulación, descentralización y participación en el agua potable rural chilena
Authors:   Centro de Estudios del Desarrollo Regional y las Políticas Públicas (CEDER), Universidad de Los Lagos, Región de Los Lagos, Chile, Pareja-Pineda Claudio
Published: December 2024

Chile ha logrado entregar agua potable de manera amplia y segura en contextos rurales a través de un esquema de coproducción. Esta forma de operación ha funcionado por más de 60 años y entrega agua a más del 10 % de la población. Sin embargo, la literatura reporta heterogeneidad en los resultados de cada territorio. En tal contexto, se está implementando una nueva legislación que institucionaliza dicha forma de provisión generando nuevas demandas en el Estado. Ante esto, el artículo analiza si la ley avanza en tres aspectos de la gestión integrada del agua potable rural. A partir de un análisis de contenido de la nueva ley y su reglamentación se concluye que existen avances en participación, articulación intersectorial y descentralización, pero se proyectan posibles conflictos al interior de la administración del Estado y en la vinculación de éste con las organizaciones. Se concluye que es importante para la política pública de agua potable rural mayor coordinación con otros sectores y también mayor atención a las tendencias actuales en administración pública respecto de la gestión estatal que abogan por una mayor articulación, descentralización y participación.

La cuenca del río Guayas en Ecuador es la más grande en la vertiente Pacífico de Suramérica, con un área de 34 500 km2 (12.57 % del territorio nacional). Dentro de la cuenca, el embalse Daule-Peripa constituye la mayor reserva de agua del país, garantizando agua para consumo de más de ocho millones de personas, además de riego y generación hidroeléctrica. Se ha desarrollado un Sistema Hidrológico de Ayuda a la Decisión (SHAD) para gestionar eficientemente los recursos hídricos en la cuenca del río Guayas, mejorar la producción energética de las centrales hidroeléctricas y alertar tempranamente de inundaciones aguas abajo de las centrales. El SHAD integra un módulo de adquisición de datos en tiempo real, con el modelo hidrológico de tanques encargado de estimar los ingresos a los embalses en escala horaria, y el módulo de control sobre el que interaccionan los gestores. El modelo hidrológico se ha calibrado separadamente para las cuencas Daule-Peripa y Baba con datos horarios del periodo 2019-2021. Para la cuenca de Baba, el coeficiente Nash-Sutcliffe para la validación a escala diaria y horaria fue 0.77 y 0.71, respectivamente, así como 0.62 y 0.49 para Daule-Peripa. El análisis preliminar comparativo de la gestión de los recursos hídricos de la cuenca realizada desde la puesta en operación del SHAD muestra evidencias de mejoras significativas.

A pesar de su importancia, existe relativamente poca investigación centrada en el riesgo por sequía en las ciudades. Por ello, el presente trabajo tiene como objetivo proponer una metodología para la evaluación del riesgo por sequía hidrológica en áreas urbanas de México y sus respectivos organismos operadores de agua potable, alcantarillado y saneamiento (OOAPAS). Esta metodología se aplicó en dos de las zonas urbanas más importantes del país: el área hidropolitana de Monterrey (AHM), y el área metropolitana de Guadalajara (AMG). El periodo de estudio fue de 2008-2018. Para la evaluación del riesgo se adoptó el enfoque contextual, que define este concepto en función de la amenaza, exposición y vulnerabilidad del sistema analizado. Para el cálculo de la amenaza se utilizó el índice de sequía de los caudales fluviales (SDI-12), y para la evaluación de la vulnerabilidad y la exposición se emplearon indicadores socioeconómicos, ambientales y de gestión institucional. Los resultados indican que las áreas de estudio son muy sensibles a las sequías hidrológicas, es decir, al déficit de escurrimientos superficiales que ingresan a sus fuentes de abastecimiento de agua. La tendencia del índice de vulnerabilidad en estas áreas va a la baja. Con respecto al índice de exposición y riesgo por sequía, la tendencia es ir en aumento en ambas áreas. Los resultados obtenidos demostraron que la metodología propuesta es factible y útil en la evaluación del riesgo por sequía en las áreas de estudio, y puede ser aplicada en otras zonas urbanas del país.

Published: December 2024

Las crecientes de diseño (CD) permiten dar dimensión por seguridad hidrológica a las obras hidráulicas de protección. Su estimación más confiable se obtiene con el análisis de frecuencias (AF) univariado, el cual representa los gastos máximos anuales disponibles, con una función de distribución de probabilidades (FDP) idónea, para estimar las predicciones buscadas. En este estudio, el AF se realiza con el enfoque trivariado, procesando un registro base de gastos QX y otros dos auxiliares, QY y QZ, que están correlacionados con el primero y tienen igual amplitud. Se describe con detalle cómo se verifica que los gastos QX, QY y QZ sean simultáneos, es decir, que pertenezcan al mismo evento analizado. La FDP conjunta trivariada de gastos se obtuvo mediante la función Cópula de Gumbel-Hougaard, que mostró excelente ajuste y reprodujo la dependencia observada en los gastos. La aplicación numérica expuesta procesó 43 gastos anuales y se realizó en las estaciones hidrométricas Tempoal como base, y El Cardón y Terrerillos como auxiliares del sistema del río Tempoal de la Región Hidrológica No. 26 (Pánuco), México. Para la búsqueda de las FDP marginales idóneas se utilizó el diagrama de cocientes de momentos L, y además se aplicaron para contraste de predicciones las FDP Kappa y Wakeby.

Authors: Melo Brenda Loren de Almeida , Pereira Nathamy da Silva , Santo Cleyton Svicero da Silva , Pilar Mateus Roveda , Silva Débora Gonçalves da , Roveda Luís Fernando
Published: December 2024

Objective: The objective of this study is to investigate the chemical characterization of the Guraguaçú River, motivated by its significant socio-economic and environmental importance in the coastal region.
 
Theoretical Reference: Trace elements are natural constituents present in water bodies, but in limited concentrations, and can perform both essential and toxicological functions. The presence of trace elements can be used as indicators of pollutants of anthropogenic origin that can compromise water quality.
 
Method: The methodology adopted for this research included the collection of 40 samples along the course of the Guraguaçú River at 20 sampling points during periods of low tide. The samples were collected and the appropriate chemical extractions carried out at the Ecology and Conservation Laboratory (LABEC). The metal readings were taken at the Plant Nutrition Laboratory of the Federal University of Paraná (UFPR), using the inductively coupled plasma atomic absorption spectrophotometry (ICP-AES) method.
 
Results and Discussion: The results obtained indicated that, of the 15 chemical elements analyzed, phosphorus (P), aluminum (Al), arsenic (As), lead (Pb), iron (Fe), boron (B), zinc (Zn) and manganese (Mn) exceeded the limits established by CONAMA Resolution 357/2005. On the other hand, nickel (Ni), silver (Ag), cobalt (Co), silicon (Si), potassium (K), sodium (Na) and calcium (Ca) were found to be within the regulatory parameters. The results of this study suggest that the Guraguaçú River has concentrations of trace elements that may pose risks to human health, especially in areas adjacent to sources of anthropogenic pollution.
 
Research Implications: Continuous monitoring is essential to mitigate adverse environmental impacts and safeguard the communities that depend on this water resource for their daily activities.
Public Policies For the Inclusion of Deaf Venezuelans as Migrants or Refugees in Brazil
Authors: Rosa André , Fellini Dinéia Ghizzo Neto , Salazar Sebastian Daniel Castillo
Published: December 2024

Objective: Although deaf and hearing individuals have rights guaranteed by the Brazilian Constitution and other regulations, these documents do not always address the economic, social, and linguistic vulnerabilities of deaf migrants. Thus, this study aims to analyze public policies for this population and identify the challenges faced by the community in Brazil.
 
Theoretical Framework: To achieve this, several guiding documents will serve as the foundation: the Federal Constitution (1988), the Law of Guidelines and Bases of National Education (1996), the Brazilian Refugee Law No. 9,474 (1997), the Migration Law No. 13,445 (2017), among other legal frameworks focused on individuals with deafness.
 
Method: As this is a documentary research study with a qualitative approach, the methodology involves consulting primary and secondary sources to substantiate the results and analyses.
 
Results and Discussion: The findings indicate that while public policies exist to support the Brazilian deaf community, they fail to accommodate the linguistic realities of Venezuelan deaf individuals. This is especially evident in educational policies which, despite promoting inclusion, remain limiting for foreign populations.
 
Research Implications: Based on these premises, the study underscores the importance of discussing the inclusion of vulnerable groups, migrants, and refugees—particularly deaf children in school-age phases. This debate must consider the interaction of four languages: Portuguese, Spanish, Venezuelan Sign Language, and Brazilian Sign Language.
 
Originality/Value: Given the lack of research in this area, this study is essential in the current context of migration in Brazil.
Variant in the Zinc Finger Domain of GLI1 underlies Post Axial Polydactyly Type B
Authors: Ahmed Zaheer , Shah Syed , Zaid Rimsha , Jabbar Abdul , Shahid Adeel , Baloch Nizam , Khan Muhammad , Umair Muhammad
Published: December 2024

Background: Polydactyly is a hereditary condition in humans resulting from abnormalities in genes related to the development of autopods. This disorder can be inherited in an autosomal dominant or autosomal recessive pattern. GLI1 functions as a moderator in the hedgehog signaling pathway. Upon binding the hedgehog to its receptor, GLI proteins are activated, leading to the expression of genes responsible for bone patterning and establishment.
Methods and Result: Here, we describe the clinical and molecular findings of Pakistani origin family with postaxial polydactyly type B. Whole exome sequencing (WES) followed by Sanger sequencing identified a homozygous variant [c.1133C > T, p.(Ser378Leu)] residing in the zinc finger domain of the Glioma-Associated Oncogene Family Zinc Finger (GLI1).
Conclusion: This study will facilitate genetic counseling and proper diagnosis of families with related and same disorders in the Pakistani population.
Między Bukaresztem i Paryżem - podwójna geografia twórczości B. Fundoianu/B. Fondane’a
Authors: Bartosiewicz-Nikolaev Olga
Published: December 2024

The main aim of the article is to present the profile of the Romanian poet, essayist, and existential thinker B. Fundoianu/B. Fondane in the context of his relationship with French literature. The key concept here is the notion of “world literature” as understood by Pascale Casanova, who sees the literary universe as a certain territory in which there has been an unequal distribution of literary resources, making peripheral literary spaces subject to a domination process. The article presents the different stages of Fundoianu’s/Fondane’s oeuvre, showing how the author fought for his literary freedom before and after arriving in Paris from Bucharest.
U stóp kameleona. Oblicza XIX-wiecznego Paryża w epistolografii Elizy z Branickich Krasińskiej
Authors: Jeznach Klaudia
Published: December 2024

This article is an attempt to look at the Parisian correspondence of Eliza Branicka Krasińska, wife of the great poet Zygmunt Krasiński, as a story about the 19th century capital of France. The everyday life, political and social events described in Elżbieta Krasińska's letters show Paris as a city with two faces. Following the aristocrat, we reach the art studios of the most outstanding painters, watch performances in theaters and operas, and also taste the latest French literature. The prose of life is shown against the background of great history and internal changes taking place in France.
Uboczne skutki polonofilstwa, czyli o nieformalnych ambasadorach Francji. Rosa Bailly i stowarzyszenie Les Amis de la Pologne
Authors: Nossowska Małgorzata
Published: December 2024

France’s cultural diplomacy was carried out by the Service des Œuvres Françaises à l’Étranger (SOFE) through institutions such as schools, universities, and cultural and social organizations. Les Amis de la Pologne and its Secretary General, Rosa Bailly, became well-known for their work on behalf of Poland. As a result, they became informal ambassadors of French culture and language, influencing the perception and image of France in the eyes of the Polish public between 1919 and 1942. The activities of Les Amis de la Pologne and the popularity of Rosa Bailly in Poland serve as an example of the effective use of unconventional channels of cultural diplomacy by the French Ministry of Foreign Affairs.
O wartości pocieszenia. Lektura 'Radości życia' Emila Zoli
Authors: Reverzy Éléonore
Published: December 2024

This study of The Bright Side of Life seeks to identify the values of consolation in a novel that claims to be “psychological”, using the notion of “care”. Its exemplary dimension and ethical purpose are based on the codes of honest literature, and feature a female character close to those of George Sand.
„Nasza Francja”. Julian Klaczko o wartościach, wolności wyboru i lojalności
Authors: Węgrzyn Iwona
Published: December 2024

The presented text attempts to characterize the unique relationship between Julian Klaczko and France. By recalling the content of a speech delivered by the writer in 1870 at the Galician Parliament in Lviv, the forgotten 'Travel Notes' from 1871, and the 'Florentine Evenings' of autumn 1872, I aim to reconstruct the writer’s emotionally charged response to the events surrounding the Franco-Prussian War, the fall of the Second Empire, and the outbreak of the Paris Commune. This narrative proves to be not only a record of individual experience but also a generational one – a testament to the disintegration of the myth crafted by Polish Romantics, who found refuge in France after the failure of the January Uprising.
« Dans un pays d’enfance retrouvée en larmes… » – la solitude d’un étranger selon Oscar-Vladislas de Lubicz-Milosz, Lituanien de naissance, Français d’adoption, poète de génie
Authors: Kukuryk Agnieszka
Published: December 2024

Le but de cet article est de présenter le motif de la solitude tel qu’il apparaît dans l’œuvre d’Oscar-Vladislas de Lubicz-Milosz. À travers l’interprétation d’une sélection de poèmes, l’auteu montre des représentations lyriques de la solitude basées essentiellement sur les archétypes de l’enfance, qui constituent l’axe paradigmatique de l’univers poétique d’un poète aux prises avec la recherche de sa propre identité. Il s’agit également de montrer la spécificité de l’expérience individuelle de la solitude, pour laquelle la question du sens de l’existence humaine semble revêtir une importance capitale. L’approche proposée permettra non seulement de décrire le mode d’être-au-monde propre à l’homme, mais aussi de mettre en évidence le besoin métaphysiqu de l’homme, son désir d’infini, sa relation avec ce qui est transcendant par rapport à lui.
Une francophonie doublement négligée: la « Rital-littérature » en Belgique et sa réception en Italie via la traduction
Authors: Nannoni Catia
Published: December 2024

Cet article aborde la question de la « Rital-littérature », soit la littérature écrite en territoire belge par des émigré.e.s d’origine italienne ou par leurs descendant.e.s, un créneau de la littérature de migration qui, après avoir connu une certaine reconnaissance dans les années 1990–2000, pâtit actuellement d’un certain oubli en Belgique. Cette indifférence est d’autant plus marquée en Italie, pays dans lequel on analyse l’accueil de quelques écrivain.e.s rital.e.s, en se focalisant en particulier sur l’existence ou non de traductions de leurs œuvres principales, greffées sur des histoires de migration pour la plupart autobiographiques ou autofictionnelles. Utilisant à la fois les instruments de la sociologie de la traduction pour la contextualisation des œuvres et les acquis des études traductologiques sur le plurilinguisme littéraire pour rendre compte de la composition des textes, notre recherche explore les possibles raisons de cette frilosité dans la réception italienne de la littérature italo-belge et cherche à indiquer quelques pistes pour la récupération et la valorisation de ce patrimoine.
