Specific recommendations are provided on the use of discussion platforms in the educational process on the fundamentals of inclusive education, which can be realized by teachers in pedagogical universities.
Stylistic features of a literary text from the translation perspective (based on the novella “The Chimes” by Charles Dickens)
Authors: Prokofeva Anna Leonidovna , Sereda Elena Aleksandrovna
Published: November 2024

The research aims to describe the stylistic devices used by Charles Dickens in the novella “The Chimes: A Goblin Story of Some Bells that Rang an Old Year Out and a New Year In”, identifying the translation solutions chosen to render the said stylistic devices into Russian. The paper examines the stylistic devices at the lexical, syntactic, and phonetic levels, as well as studies the methods of translating the units under consideration into Russian. The research analyzes the features of the translation of the identified stylistic devices in the target text of the novella. The work is original in that it is the first one to conduct a comprehensive, multi-level study of the stylistic devices in Charles Dickens’s novella “The Chimes” from the translation perspective. As a result of the research, it was determined that the stylistic devices identified at the lexical level are the most frequent ones in the text of the novella, with similes being the most recurrent. The translator often resorts to the use of calquing to render the identified stylistic devices, thereby trying to preserve the stylistic content and expressiveness of the original work.
Contemporary animalistic subcultural practices and their precedents in Russian linguistic culture
Authors: Shkapenko Tatiana Mikhailovna , Gorodetskaia Ekaterina Aleksandrovna
Published: November 2024

The study aims to identify the attributive features that constitute a new subculture for Russian society, “the quadrobers”, based on its comparison with the morphology of the ritual of “ryazhenie” (traditional masked revelry). This innovative behavioral practice has caused a wide public resonance in Russia, characterized by contradictory assessments and interpretations. Justifications used include categorizing quadrobics as a sports entertainment, as well as references to the precedent connection of this new trend with the tradition of “ryazhenie” in Russia. The scientific analysis of probable intertextual connections between the two play-related phenomena is undertaken for the first time, which determines the scientific novelty of the work. As a result of the analysis, it was revealed that teenage animalistic practices share only superficial similarities with the transformations of “ryazhenie” performers. Distinctive features of Russian cultural tradition are its ritual nature and sacralization, its connection to specific cyclical events, the interactive nature of the theatricalized action with a stable distribution of roles. In teenage animalistic subcultures, dressing up and imitating animal behavior becomes an end in itself and serves as a means of attracting attention. In a broader linguoculturological context, this phenomenon can be considered as a type of transformative games of humans with their own nature, from projective concepts of transhumanism to real practices of play-related trans-animalism.
Linguistic means of expressing the binary opposition TOP – BOTTOM in a linguocultural aspect
Authors: Suvorova Elena Vladimirovna , Romanova Yuliya Gennadyevna , Akhmetzyanova Tatyana Leonidovna
Published: November 2024

The study aims to identify and describe the linguistic means of expressing the basic opposition TOP – BOTTOM in Russian linguistic culture. The study is novel in that it is the first one to consider the linguistic means of verbalizing the binary opposition TOP – BOTTOM in parallel using Old Slavic mythological concepts, recorded in ethnolinguistic dictionaries and encyclopedias, and modern explanatory, associative, phraseological dictionaries, and the Russian National Corpus. As a result of the study, it has been found that the linguistic means that externalize the TOP – BOTTOM opposition in Old Slavic mythological concepts have not found direct reflection in the modern Russian linguistic worldview. Partially, a metaphorical reinterpretation of Old Slavic notions of the world can be observed in phraseological units, proverbs, and sayings. The anthropocentric sensitive perception of the world is preserved at the level of associative reactions and phraseological units. The emotional evaluation accompanying the points TOP and BOTTOM is ambiguous: TOP is associated with a positive evaluation, and BOTTOM with a negative one, but there is also a change from positive to negative.
Features of expressing optative modality in the Russian and Kabardian languages
Authors: Kremshokalova Marina Chaflenovna , Bizheva Zara Khagimuratovna
Published: November 2024

The research aims to identify the means of conveying optativity as a crucial modal category in the Russian and Kabardian languages. The article shows that these languages feature emotional-expressive and modal meanings conveyed by lexico-grammatical and syntactic means oriented toward expressing desirability. The research novelty lies in the fact that it is the first work to compare ways of expressing optativity in Russian and Kabardian based on scholarly works in this field and practical materials from various sources. The description of the ways to explicate the category of optative modality was based on texts of literary discourse. As a result of the research, it was found that different language resources are activated in different language systems to express modal meanings. In Russian, according to the analysis of more than 120 microtexts, only analytical ways of expressing optativity (particles and modal words) were identified, while in the Kabardian language, out of 97 fragments of texts, synthetic ways are presented: the use of affixes added to verb roots. The analysis showed that both languages have lexical elements that convey desirability, which confirms its mental essence.

Authors: Guz Maria Nikolaevna , Sitnikova Irina Olegovna , Smolonogina Elena Anatolevna
Published: November 2024

The authors of the article aim to determine the features of the use of performative practices in teaching a foreign language in higher education, namely: to establish whether certain elements of performativity are involved in teaching a foreign language at a university; if there is a correlation between certain aspects of the language, such as vocabulary and phonetics, and certain performative techniques and practices; if there is a relationship between the stage or level of language learning and the implementation of performative practices in it. The article examines specific examples of performative practices used in the educational process for the first- and third-year students. The scientific novelty of this article lies in the study of the performative component in teaching a foreign language in higher education. The authors of the article offer specific examples of performative practices developed by the staff of the department, which can be adapted to the educational process in other universities. Based on the analysis of the course of the educational process, including such a factor as the dynamics of student motivation, the authors revealed the impact of performative practices on student motivation and academic autonomy, the degree of which increases with the integration of performative practices into the educational process. As a result, the study showed that performative practices can be systematically used in teaching a foreign language in higher education. The same performative tools and practices can be effectively used at different levels of language with very little modification of their content. The content part of the training does not impose any restrictions on the use of performative means.

Published: November 2024

With the importance of learning English and being able to communicate in the learned language, language education has become a considerable issue in all age groups. This important subject has become more difficult to implement with the Covid-19 pandemic. During the distance education which is applied in long period, students have experienced various problems in the lessons. In this study, it is tried to find the reasons, solutions and alternative ways of student’s unwillingness and hesitation of English speaking during their lessons. With the aim of finding these concerns an action research method, a qualitative research method, is used. 33 prep students from the high school in Bolvadin, Afyonkarahisar have attended to study. During and at the end of the applications, data were collected by teacher diaries, students diaries and semi-structured interview form. While the descriptive analysis method was used for the diaries, contents analysis was used for the interview form. At the end of the content analysis, it was found the codes and themes of focus group discussion data. As a result of data re-coding by the co-observer, the agreement was found to be 86 percent. When the applied action research data were anaylzed, it was determined that the students were embarrassed in the lessons and because of their speaking anxiety, they participated less in the activities. It has been concluded that the willingness to speak is increased with Web 2.0 applications and the lessons that include more dialogues, reading-listening activities, games and movies will be motivating for the students.
Development and Implementation of a Value-Based Care Telehealth Emergency Medicine Program: Triage and Care Alignment in an Integrated Health System
Authors: Smith Austin , Martinez Julie , Taylor Joel , Douglas Kelcie , Bledsoe Joseph
Published: November 2024

Background: Acute unscheduled episodic care is an area of potential cost savings, given the high frequency and cost of unnecessary emergency department (ED) utilization. 
Methods: We developed a provider-assisted patient navigation program using a telehealth platform designed to decrease ED utilization and reduce costs while providing exceptional patient satisfaction. 
Results: Urgent care (UC) visits were analyzed from July 1, 2022, to June 30, 2023. The “ED comparison” group (n = 68,320) consisted of patients discharged to home after receiving care in the ED. The “avoided ED visits” group included patients (n = 7,430) who received care in a lower-acuity setting and did not require emergency services within 48 hours. The calculated overall medical expense savings comparing the costs between the ED vs. lower-acuity settings revealed that 50% (n = 450) of consultations were managed as outpatients, avoiding ED visits. Evaluation of distribution by source revealed that 67% of ConnectCare consults resulted in admission, 48% for UC, while 36% of patients were service center consults. Conversely, 31% of consultations resulted in recommendations to go to the ED, and 16% of these were assisted transfers where the Telehealth Emergency Medicine (TeleEM) clinician communicated with the receiving ED. Among the 280 patients directed to the ED, 243 were sent because of immediate clinical acuity, 28 were because of logistical or scheduling issues, three for non-qualifying insurance for outpatient workup, and six were redirected to the ED following diagnostic results. Our analysis suggests an estimated average avoided medical expense of $1,701 per case to insurers and patients if an ED visit was avoided. 
Conclusion: Implementing a TeleEM program to assist with triage and resource alignment, as well as identification and outpatient management of patients while avoiding an ED visit, is feasible within an integrated health system. Our TeleEM program may be a model for other integrated health systems.
A New Institution for Serbian Memory
Authors: Zorić Vukašin
Published: November 2024

The destruction of the joint Yugoslav state was accompanied by a sharp alteration of the country’s narrative about the country’s experience of the Second World War, which shifted from a focus on the Yugoslav partisans to ethnically-classified civilian victims of war. In 1992, the Republic of Serbia founded the Genocide Victims’ Museum, which was responsible for the preservation of the memory of the victims of the genocide of Serbs, Jews, and Roma; the collection of information on war atrocities; and was also intended to fulfill the country’s obligations under the International Convention on Genocide Prevention and Punishment. This article explores the Genocide Victims’ Museum’s memory strategy in the context of contemporary Serbian history. It also analyzes the transformation of the narrative of victimhood formulated or supported by a state-sponsored institution, interpreting it as exemplary of the “shift from heroization to victimization” in the politics of memory within the European context.
On Victims, Heroes, and Gulag-gupvi Survivors
Authors: Iordachi Constantin
Published: November 2024

Employing a biographical, oral history approach, this article documents the life story of a war veteran and gupvi survivor in Hungary to illustrate the multiple synchronic as well as diachronic cleavages that exist between the official, societal, and collective memory regimes in postcommunist Eastern Europe. István Bicskei’s life story highlights, in a tangible way, the fact that the socially constructed notions of victimhood and heroism vary as a complex outcome of the interaction of multiple forms of human, institutional, and political agencies in an ever-changing historical context and in multi-layered cultural milieux. The article argues that these key cultural notions are closely tied to individual understandings of personhood, to national and collective identities, but also to ruling ideologies and political regimes. The article also highlights the glaring gap between official, scholarly, and local narratives about the past that exists in marginalized rural communities and points to the conspicuous lack of cultural “mediators” or “intermediators” between these distinct political, media, and social spheres, and between official and grassroots memory narratives.
The 1890s Bicycle Boom in the Ukrainian Lands: Local Mobilities between Technological Westernization and Imperial Politics
Authors: Martynyuk Olha
Published: November 2024

This is the first comparative study of the 1890s Bicycle Boom in the Ukrainian lands, which at that time were part of the Habsburg and Romanov Empires. This article reconstructs the world of bicycle producers, retailers, advocators, consumers, and riders, focusing on local agency in the adoption of Western cycling technologies. A comparison of bicycle clubs in the Ukrainian lands of the two empires illustrates how distinct imperial, ethnic, social, and gender politics influenced the social construction of cycling technologies. This article presents a portrait of technological progress in which local enthusiasts were key drivers of innovation, whereas the two imperial states responded with regulatory measures rather than actions that would promote technological development. Although Eastern Europe was late in launching its own mass production of bicycles, the cultural phenomenon of the 1890s Bicycle Boom in the Ukrainian lands, which stimulated great enthusiasm, public debates, and new standards of bodily performance, emerged simultaneously with the boom in bicycle-producing Western societies.
Socialist Wardens and Guards in Czechoslovakia and East Germany: The Replacement and Political Indoctrination of Prison Staff
Authors: Pinerová Klára
Published: November 2024

This article focuses on the replacement of prison staff in Czechoslovakia and East Germany, later the German Democratic Republic after 1945. The main focus is on the question of how the replacement of prison staff took place, what strategies Czechoslovakia and East Germany used to accomplish this task, and the extent to which local conditions and the overall evolution of the prison systems of the two countries played a role in the process. The other aim of the article is to understand the place of political indoctrination in the staffing of prisons in the two socialist countries and to show how the system of teaching new members of the prison staff changed over time. Comparing the replacement of prison staff shows that although both states were under Soviet influence and transformed their prison systems according to the Soviet model, the implementation of staff changes greatly depended on the distinct political, economic and social conditions of the two states.

Published: November 2024

The Corona River in Tamaulipas, Mexico, originating from the San Pedro Hill in the Sierra Madre Oriental, serves as a crucial water source for the region and flows into the Vicente Guerrero Dam. Given its significance, assessing the river’s water quality is imperative. Rivers are often vulnerable to contamination from organic and inorganic discharges, which can degrade water quality. This study conducted a comprehensive assessment across eleven sampling stations along the Corona River, analyzing fecal coliforms (43-2400 Most Probable Number or MPN) and heavy metals [cadmium (0.004-0.037), copper (0.0085-0.0595), and lead (0.142-0.227 mg L-1)]. Elevated levels of fecal coliforms and heavy metals were detected at various stations, with contamination progressively increasing towards the river’s confluence with the Vicente Guerrero Dam. These findings indicate that the water quality may deteriorate to levels unsuitable for consumption. The data presented are crucial for informing relevant authorities on the necessity of implementing effective management, prevention, control, and treatment strategies to ensure that the river water meets safety standards for various uses, including consumption, recreation, agriculture, and livestock.

Published: November 2024

La ehrlichiosis monocítica canina (EMC), es una enfermedad infecciosa transmitida por garrapatas que desencadena una respuesta inflamatoria aguda en caninos. El presente estudio tuvo como objetivo evaluar las alteraciones del proteinograma sérico en caninos con EMC, con el fin de identificar posibles biomarcadores para el diagnóstico y seguimiento de la enfermedad. Se analizaron muestras de suero de ocho caninos con diagnóstico confirmado de EMC mediante reacción en cadena de la polimerasa. Los resultados del proteinograma revelaron alteraciones significativas en las fracciones proteicas. Se observó en siete casos hipoalbuminemia, en seis hipogammaglobulinemia, en siete casos hiperalfa-2 globulinemia y en dos casos hiperbeta-globulinemia. Estos hallazgos sugieren una disminución en la síntesis de proteínas hepáticas, una respuesta inmune alterada y un proceso inflamatorio activo. La hipergammaglobulinemia policlonal, identificada en dos casos, sugiere una activación crónica del sistema inmunológico. A diferencia de la hipogammaglobulinemia, que se presentó en seis pacientes, esta condición no es una manifestación común de la enfermedad y podría estar vinculada a los procesos patogénicos de la EMC, además de aumentar la predisposición a infecciones secundarias. En conclusión, el proteinograma sérico es una herramienta útil para evaluar la respuesta inflamatoria en los casos de EMC. Las alteraciones observadas en las fracciones proteicas pueden servir como biomarcadores para el diagnóstico y monitoreo de la enfermedad. Este estudio establece las bases para futuras investigaciones que profundicen en la comprensión de la patogénesis de la enfermedad y en el desarrollo de nuevas herramientas diagnósticas.

Published: November 2024

El litoral marino se ve afectado por las considerables cantidades de microplásticos (MPs), primarios y secundarios. En el Puerto Matarani, ubicado en el departamento de Arequipa, al sur de Perú, se realizan actividades como la pesca y la extracción de mariscos. El objetivo del presente trabajo fue caracterizar los MPs en el caracol marino Thaisella chocolata. Se recolectaron 150 individuos de T. chocolata en dos zonas. La zona A se encuentra a 100 m de distancia del muelle del puerto de Matarani, en donde reposan las embarcaciones de pescadores artesanales y, la zona B, es una lobera ubicada aproximadamente a 2 km de distancia del muelle. Las recolecciones se realizaron en las temporadas de invierno y primavera de 2021. La digestión del tejido del caracol fue realizada con KOH 10%, se usó NaCl concentrado para la separación de los MPs, se filtró; y, finalmente, se determinaron y midieron los MPs hallados por microscopía, además de determinar la composición mediante microscopía de Raman. En el 100% de los caracoles colectados se registró MPs. Las formas más abundantes fueron filamentos > fibras > fragmentos. El color dominante fue el azul (53,94%) y el rango de tamaño más frecuente fue 0,0825 a 0,1609 mm (45,9%). En la temporada de invierno y los caracoles hembra de la zona B presentaron la mayor abundancia de MPs (5,74 y 2,74 MPs/ind., respectivamente). No se halló relación directa entre la longitud de la conchilla y el peso del tejido de T. chocolata en función a la cantidad de MP/ind. Mediante la microscopía de Raman se determinó la presencia de PPO (Óxido de poli(2,6-dimetil-1,4-fenileno)), PPSU (polifenolsulfona), PDMS (poli (dimetilsiloxano-co-metilfenilsiloxano)), PBT Poli (tereftalato de 1,4-butileno), PVBP (Poli (4-vinil bifenilo) y PS (Poliestireno). Se concluye que, en base al sexo y temporada de evaluación, el caracol T. chocolata puede ser empleado como un bioindicador de contaminación MPs, caracterizados por su forma, color, tamaño y composición química en el ecosistema marino costero peruano.
Enzootic calcinosis in sheep exposed to hay contaminated with Solanum glaucophyllum
Authors: Ovelar M.F. , Vilatuña E. , Scioli M.V. , García Juan Agustin
Published: November 2024

Enzootic calcinosis (EC), by ingestion of toxic plant Solanum glaucophyllum, is a well-known chronic disease in Argentina affecting cattle under extensive grazing systems. It is characterized by systemic calcification of soft tissues, that can progress to death when severe cardiovascular lesions are present. We describe an episode of EC in sheep after exposure to hay contaminated with S. glaucophyllum. In a sheep flock of 17 male, 8-10 months old, 2 died spontaneously. Grossly, hydrotorax, lung edema, and aorta artery and myocardial multifocal-coalescing mineralization was observed. Microscopically, systemic mineralization of blood vessels was present in aorta, kidney and heart characterized by basophilic granular deposits in tunica intima and/or tunica media. Myocardial multifocal-coalescing areas of myofiber loss and regeneration, characterized by macrophage and satellite cell infiltration intermingled with fine granular basophilic deposits (mineralization) was evident. Von Kossa stain confirmed mineralization as calcium deposits. Furthermore, sheep outbreaks are sparsely reported, contributing to knowledge of the disease in other species, in addition to cattle, and in an unusual presentation as forage reserves. During hay production, inspection of possible toxic plants, such as S. glaucophyllum, must be carried out.
Hypovitaminosis A in two beef calves
Authors: Pachiani M. , Livio J.M , Cantón German J.
Published: November 2024

Hypovitaminosis A is an uncommon disease in grazing livestock systems, as the primary source of precursors (carotenes) is fresh forage. However, under environmental circumstances predisposing to the development of poor-quality forage, vitamin A deficiency and associated clinical signs can occur. This article describes the clinical findings of hypovitaminosis A in two 2-months-old calves in beef herd in Ayacucho, Buenos Aires Province, in November 2023. Blindness was the only clinical sign observed in a beef herd.. Low vitamin A concentration was detected in blood of affected and non-affected calves and their mothers ranging from 7.8 to 24.8 μg dL-1 in calves and from 15.5 to 28.9 μg dL-1 in cows (reference 25-35 μg dL-1 in calves and 40-50 μg dL-1 in adults), confirming the deficiency status of the herd. During gestation, dams were fed corn-harvested hay. This diet may have been a poor source of carotene, leading to reduced hepatic reserves of vitamin A in the calves at birth. Consequently, clinical signs may have occurred during the first few weeks when these reserves were depleted.

Revisión de la patogénesis molecular del aborto por Brucella
Authors: Rossetti C.A.
Published: November 2024

La brucelosis es una enfermedad infecciosa crónica, zoonótica, de amplia distribución mundial causada por bacterias del género Brucella spp. En las especies animales susceptibles, el principal y muchas veces único signo clínico es el aborto. El aborto, además de producir pérdidas económicas en las explotaciones pecuarias, es el elemento más importante para que la enfermedad se disemine y perpetúe, generando también problemas en la salud pública. Sin embargo, es muy poco lo que se conoce acerca de los mecanismos moleculares que lo ocasionan. Brucella spp. muestra un especial tropismo por el útero gestante en el último tercio de la preñez, donde sobrevive y se reproduce en el interior de los trofoblastos. El alto número de bacterias dentro de los trofoblastos desencadena la apoptosis de las células infectadas por estrés del retículo endoplásmico. La destrucción masiva de trofoblastos resulta en una placentitis fibrino-necrótica, que dificulta el intercambio nutricional y gaseoso entre la madre y el feto, y la interrupción de la gestación se produce cuando los placentomas sobrevivientes no son suficientes para mantener activa la gestación. La interacción de Brucella con los trofoblastos no se ha estudiado en detalle, y muchos eventos de esa interacción, se infieren a partir de las observaciones en otros tipos celulares. En este artículo se describen los factores de virulencia de Brucella que intervienen en la adherencia, invasión y replicación intratrofoblástica de la bacteria, y las consecuencias locales que desencadena, y se discute la acción preventiva de la vacunación sobre el aborto. Finalmente se muestran varios modelos de estudio in vitro o ex vivo disponibles que no han sido explotados y que podrían brindar mayores datos sobre la patogenia molecular del aborto por Brucella.

Authors: Wati Putri Sih Fanta , Sutikno Putri Yanuarita
Published: November 2024

This study aims to test the effectiveness of the song-assisted Discovery Learning learning model for science students’ learning outcomes. This happened because students still needed clarification about sorting digestive organs. This study uses an experimental method with a quantitative approach. The population of this study is grade V students of Sragen 6 State Elementary School, Sragen Regency, with a total of 62 students. Sampling was conducted with saturated samples, with 25 V-A students as the control class, 25 V-B students as the experimental class, and 12 as the instrument trial. The data collection techniques used are written tests, observations, and documentation. Data analysis techniques using prerequisite tests include instrument validity and reliability, initial data analysis with normality and homogeneity tests, and final data analysis using t-test and n-gain test. The study results showed a positive effectiveness of using the discovery learning model with an increase in the learning outcomes of grade V students; the calculation value was more significant than the table (3,767 > 2,012). H0 is rejected, and Ha is accepted, meaning there is a difference in learning outcomes between the pretest and posttest in learning using the Discovery Learning learning model. Based on the above analysis, the posttest results show that the learning outcomes between the experimental class are higher than those of the control class. The difference is due to the treatment difference between the experimental and control classes. This study concludes that the discovery learning learning model effectively improves the learning outcomes of grade V students of Sragen 6 State Elementary School. The suggestion for this study is that teachers need to apply the discovery learning model as one of the innovative learning models to improve student learning outcomes.

Marine ship hulls' corrosion resistance behavior under static and flowing conditions was investigated. The metal of the hull panels of marine ships was chemically and mechanically examined and analyzed, revealing that carbon steel type DIN 1.0501 C35 is employed in constructing the hull of ships in the port of Basrah in Iraq. A corrosion resistance test for this metal was carried out in laboratory-prepared seawater under static and flowing conditions at a flow rate of 1500 liter/hour and various immersion times (12, 24, 48, 120, 168, 336) hours. The temperature was kept constant at 30°C, and a fixed salt concentration of (3.5% sodium chloride). The corrosion rate of C35 carbon steel was calculated using the weight loss method is an effective method for calculating the corrosion rate of carbon steel. The samples were examined using a scanning electron microscope (SEM) for corrosion analysis. Conclusions from this research indicate that an increase in the flow rate resulted in an elevation of the corrosion rate, doubling the corrosion rate compared to samples under static conditions. The corrosion rate exhibited a significant increase during the first 24 hours, followed by a gradual decrease with increasing immersion time. The corrosion rate increased by 682.9%. The speed of corrosion was fast initially, but the weight loss slowed after 24 hours of immersion. A scanning electron microscope (SEM) examination revealed that the flow environment was aggressive for carbon steel. It was much more severe, and the pits and grooves were more significant than the static condition.

The comfort and safety of drivers greatly depend on the design of the suspension system in ‎road cars. The study presents modeling and control of an Active Suspension System (ASS) ‎for a ¼ car with two degrees of freedom, considering unknown masses, time delay, and ‎various types of road disturbances using the MATLAB/Simulink environment. The study ‎examines the performance of the Model ‎Predictive Control (MPC) scheme. ‎Numerous controllers are utilized in literature, including Artificial Neural Networks (ANN), ‎fuzzy logic controllers, Linear Quadratic Regulators (LQR), and Proportional Integral ‎Derivative (PID) controllers. An MPC setup for the ASS model was presented in this paper. ‎MPC is an optimal control strategy that predicts future output using a plant model. The ‎performance of MPC was compared with that of an LQR control method. The results indicate The MPC can produce better road holding, and handling and ride quality are greatly improved by the LQR. The MPC control is 87% faster at eliminating oscillations compared to LQR which is 30%, The conclusion emphasizes that the effectiveness of the MPC ‎scheme is far superior to LQR in all aspects. Despite certain challenges, such as reduced effectiveness under severe overload and increased energy consumption with larger loads.

Introduction. According to the International Federation of Gynecology and Obstetrics (FIGO) classification placenta percreta is the most severe form of placenta accreta spectrum (PAS) which is characterized by placental invasion through the entire myometrium and possible involvement of extrauterine tissues. The disease is associated with prior cesarean sections and placenta previa. This paper presents a clinical case of placenta percreta. The diagnosis was made based on ultrasound and MRI and confirmed intraoperatively. Histological examination revealed thinning of the uterine segment, fibrosis of the posterior wall of the bladder, and adhesions between the uterus and the bladder. We aimed to compare clinical, instrumental, and histological data and intraoperative imaging. Materials and methods. Histological study was performed on paraffin sections (H&E and Mallory staining). We studied immunohistochemistry of cytotrophoblasts and syncytiotrophoblasts with antibodies to cytokeratin-8. Results. MRI and ultrasound examination showed placental invasion extending beyond the serous lining of the uterus and involving the posterior wall of the bladder. At 37 weeks, elective cesarean section and surgical excision of the uterine wall with invaded villi were performed. Histological study revealed invasive cytotrophoblasts in the uterine wall and fibrous bladder wall. Involvement of the bladder wall was due to adhesions and the development of fibrosis. Conclusion. Trophoblast and villous invasion did not extend beyond the uterus. Placenta percreta can be supposed to be one of the forms of pelvic adhesive diseases.

Uma número crescente de pessoas, tem buscado na utilização de suplementos alimentares, principalmente os de fontes naturais, uma estratégia para melhorar as condições de saúde. Os suplementos alimentares podem ser definidos como componentes alimentares, nutrientes ou composto não alimentar, ingerido propositalmente, a fim de atingir benefícios específicos para a saúde e/ou desempenho. Conforme proposto recentemente pela declaração de consenso do Comitê Olímpico Internacional. Adicionalmente, há um reconhecimento crescente da importância dos alimentos antioxidantes na promoção da saúde e bem-estar da vida humana. Esses compostos desempenham papéis vitais na proteção do organismo contra agentes infecciosos e aumento do estresse oxidativo. Este que, por sua vez, está envolvido na patogênese de várias doenças degenerativas, incluindo doenças crônicas não transmissíveis (DCNT) e risco cardiovascular aumentado.

Bruikbaarheid van ChatGPT-4V(Vision) om lugfoto’s te ontleed, dryfvere wat aanneem kan bevorder en implikasies vir Geografie-klaskamers
Authors: van Staden Christina Johanna

ChatGPT-4V kan lugfoto’s redelik suksesvol ontleed, tog is die implikasies daarvan vir Geografie-klaskamers nog nie ondersoek nie. Die doel van hierdie verkennende gevallestudie was drievoudig, naamlik om te bepaal (a) hoe bruikbaar ChatGPT-4V is om lugfoto’s te ontleed, (b) watter dryfvere die aanneem daarvan kan bevorder en (c) wat die implikasies vir Geografie-klaskamers kan wees indien dit aangeneem word om lugfoto’s te ontleed. Ek het eers tien gesprekke met ChatGPT-4V gevoer om sy geografiese kennis en ontleding van lugfoto’s te beoordeel. Daarna het ek die Kunsmatige-Intelligensie-Aanvaarding-Voorspelling-Model (KIAVM) toegepas om die dryfvere te identifiseer wat die aanneem van ChatGPT-4V kan bevorder. Laastens is die implikasies vir Geografie-klaskamers bepaal. ’n Gemengde-metodes-benadering is gevolg. Die gesprekke was kwalitatief van aard, terwyl kwantitatiewe data tydens die toepassing van die Kunsmatige-Intelligensie-Aanvaarding-Voorspelling-Hulpmiddel (KIAVH) ingesamel is. Die bevindinge toon dat ChatGPT-4V bruikbaar is om lugfoto’s te ontleed. Die gehalte van sy geografiese kennis is redelik goed, die lugfoto’s is redelik suksesvol ontleed en ChatGPT-4V kon lugfoto’s gebruik om ’n gevallestudie en ’n toets (beide met memoranda) te skep. ChatGPT-4V het min taalfoute gemaak, maar dit kon oortuigend hallusineer. Agt van die nege dryfvere van die Kunsmatige-Intelligensie-Aanvaarding-Voorspelling-Model kan die aanneem van ChatGPT-4V in Geografie-klaskamers kan bevorder. Daar kan voorspel word dat ChatGPT-4V vir etiese en onetiese doeleindes aangeneem sal word, daarom behoort beleid en strategieë in plek gestel te word om verantwoordelike gebruik te bevorder. ChatGPT-4V hou belangrike implikasies vir Geografie-klaskamers in. Onderwysers en dosente kan dit gebruik om hulle werkslas te verlig aangesien die response goed is en die foute maklik reggestel kan word. ChatGPT-4V kan gebruik word om gedifferensieerde onderwys te bevorder aangesien verpersoonlikte leergeleenthede geskep kan word. Leerders en studente moet egter gemaan word om sy response krities te beoordeel. Kostes kan bespaar word en toegang tot lugfoto’s kan bevorder word. Indien ’n leergeoriënteerde benadering tot assessering gevolg word, kan geleenthede vir KI-plagiaat beperk word.
