Authors: Nuradnin Ananda Haura , Mozartha Martha , Kesumaputri Bebbi Arisya , Anastasia Danica
Published: November 2024

Shade matching of multi-shade dental resin nano-composite is a process that requires time and operator expertise. Single-shade universal composite resin claimed to match all tooth colors to simplify the process. Comprehensive testing, including an assessment of surface hardness, is needed to evaluate the properties of this relatively new single-shade universal composite and to evaluate the surface hardness of single-shade universal composite compared to multi-shade dental resin nano-composite. This experimental study tested two composite restorative materials: single-shade universal composite (Omnichroma, Tokuyama Dental, Japan) and nanofilled composite resin (FiltekTM Z350 XT, 3M/ESPE, USA). Thirty specimens divided into 2 groups (n=15) were fabricated by placing the composites into a stainless steel mold (2 mm thick × 12 mm diameter) and photoactivated for 20 seconds, followed by finishing and polishing. Surface hardness was evaluated using a Vickers hardness testing machine and a diamond indenter with a load of 1000 g applied for 15 seconds. Data were analyzed by using an independent t-test. The mean surface hardness of single-shade universal and multi-shade dental resin nano-composite were 21.04±4,92 and 19.33±5,61 Vickers hardness number (VHN), respectively. Single-shade universal composite showed no significant difference in surface hardness to multi-shade dental resin nano-composite (p-value 0.05). The surface hardness value of single-shade universal composite resin was comparable to multi-shade dental resin nano-composite.

Authors: Bhatta Bijay Raj , Shrestha Samrat , Shakya Niliza , Shrestha Mecklina , Thapa Kaushal Samsher
Published: November 2024

Adult midgut volvulus is a rare surgical disease, with an estimated incidence of less than 0.15%, and more common in Asia and Africa as compared to Europe and the US. It is a developmental anomaly characterized by failure to complete normal fetal rotation of the midgut around the Superior Mesenteric Artery (SMA) inside the peritoneal cavity. Though rare, adult midgut volvulus has the potential for bowel ischemia-related complications, and thus clinicians should have a reasonable index of suspicion to diagnose this. Early computed tomography (CT) scan with diagnostic accuracy of more than 83% would help in early recognition and management of these rare causes of intestinal obstruction. In this study, we reported the case of an adult primary midgut volvulus in a 30-year-old male who presented with features of acute bowel obstruction with a history of similar recurrent episodes and renal transplant. Diagnosis of midgut volvulus was made based on contrast-enhanced CT findings, and Ladd’s procedure was performed.

Published: November 2024

A 70-year-old male patient with a history of systemic hypertension, gouty arthritis, and possible chronic kidney disease presented with right flank pain, nausea, and decreased appetite. Examinations revealed a right-sided incarcerated diaphragmatic hernia in the anterior region, with protrusion of adipose tissue and loops of small intestine. A laparoscopic surgery was performed, during which the herniated contents were reduced, and a hernia defect approximately 4 cm in size was found and repaired. Post-surgery, he developed complications including pulmonary thromboembolism, intestinal perforation, and fistula, which required reoperation, and progressive clinical deterioration, ultimately leading to death. This case report presents a rare instance of congenital hernia diagnosed through imaging after the onset of nonspecific clinical symptoms. It emphasizes the importance of considering this pathology among differential diagnoses of acute abdomen for prompt diagnosis and appropriate management through surgical intervention.
Formação Inicial de Professores de Matemática na Modalidade à Distância no Brasil: o Que Dizem as Pesquisas dos Últimos Dez Anos
Authors: Fontes Cilene , Delgado Karina Valdivia , Gramorelli Marcelo Aparecido Feitosa , Parpineli Cavalcante Camila
Published: November 2024

A temática da “formação inicial de professores de matemática” desperta o interesse de pesquisadores que buscam identificar nuances que influenciam esse processo educacional. Com o advento da internet, essa capacitação também passou a ser realizada integralmente de forma remota, entretanto, estudos sobre essa modalidade de ensino ainda são escassos na bibliografia. Este trabalho tem como objetivo geral analisar e sintetizar de maneira abrangente as evidências disponíveis na produção acadêmica dos últimos dez anos, a fim de compreender o estado atual da formação inicial de professores de matemática à distância no contexto brasileiro. Para isso, realizou-se uma pesquisa qualitativa, do tipo revisão sistemática da literatura, com a coleta de dados realizada por meio de buscas em repositórios acadêmicos de teses e dissertações. Amparados nos pressupostos da teoria de análise de conteúdo, obtivemos resultados que mostram que essa modalidade educacional, a distância (EaD), tem se mostrado uma estratégia eficaz para ampliar geograficamente o acesso ao ensino superior e democratizar sua oferta. Contudo, o estudo evidencia que ainda há aspectos que demandam aprimoramento, especialmente na interação entre tutores e alunos, nos processos avaliativos e na qualidade do ensino oferecido.

Authors: Quimis Arteaga Luis Edwin
Published: November 2024

El gobierno ecuatoriano utiliza TikTok como herramienta de comunicación para fortalecer su imagen de poder y autoridad en la campaña del referéndum y consulta popular de 2024. A través de la “teatralidad del poder,” los videos difundidos en esta plataforma despliegan una estrategia visual y discursiva destinada a legitimar el rol gubernamental, representando a militares y policías como protectores de la ciudadanía y justificando el uso de la violencia estatal como recurso para garantizar la seguridad pública.

Published: November 2024

La reconfiguración mundial ha establecido condiciones en la esfera material de vida, generando un profundo impacto, especialmente en la movilidad humana. Para este trabajo se reflexiona sobre el tratamiento mediático y discursivo de la migración que aspira a la gestación de un imaginario social, vinculado a la reproducción de una ideología racista y de jerarquización social que, a escala sistémica, que criminalice a la movilidad “irregular” de personas. Los discursos que caracterizan y representan a las personas en movilidad como sujetos despojados de su condición humana, difundidos desde nuevos y tradicionales medios de comunicación cuyo alcance no posee precedentes, se presentan como los principales mecanismos de reproducción de este imaginario.

Regional Odontodysplasia: A Rare Developmental Anomaly
Authors: Buktare Komal , Parikh Shilpa , Shah Jigna
Published: November 2024

Regional Odontodyplasia (RO) is a rare abnormality of unknown aetiology affecting dental tissue derived from mesoderm and ectoderm. It occurs more commonly in women, with no racial predilection and often in maxillary dentition restricting to a single quadrant. These odonto-dysplastic teeth radiographically appear as Ghost teeth with hypoplastic enamel, large areas of hypo-mineralised interglobular dentin with an irregular arrangement of dentinal tubules and denticles in the enlarged pulp cavity. This case report discusses clinical, radiological and histological findings for accurate diagnosis of RO.
Ottoman Approach to Shia and Sunni State Officers of Syria in the Examples of Fakhreddin Maanoğlu and Ali Canpolad between 1570s and 1630s
Authors: Gündoğdu Birol
Published: November 2024

Some scholars like to believe that Ottoman Sunni orthodoxy drew its form by virtue of the Ottoman conquest of Syria and Egypt in 1516-1517. Accordingly, early Ottoman understanding of heterodox Islam was replaced with a more orthodox one as core Islamic lands started to exert their influence on the Ottoman peripheries. Many recent academicians counter this traditional argument by suggesting that the role of Arab ulema in the formation of Ottoman Sunnism is quite negligible or highly limited at best. Others interpret establishment of the Safavid Empire in the sixteenth century as main motivation for Ottoman concentration of Sunni Islam in opposition to Shi’i Iran. Despite such disputes on the origin of this “confessionalization”, they are mainly in agreement that the Ottomans more and more enforced the boundaries of Sunni faith and practice within the empire especially beginning sometime in the second half of the sixteenth century. Political administrative and local studies shall confidently shed new lights on Ottoman experiences of Sunni orthodoxy. In this view, Ottoman Syria, which is situated in the middle of all these discussions, allows us to conduct a field study in the context of Sunni-Shi’i polarization during the time under scrutiny. This paper is going to be one of the first empirical articles, which exclusively focuses on Fakhreddin Maanoğlu and Ali Canpolad i.e., one Shi’i and one Sunni officer of the Ottoman Empire. Our departure point in this paper is to reveal to what extent “sunnitization” of Ottoman Empire played an important role in decision-making of the Ottoman administration between 1570s and 1630s. In a sense, this study aimed to test the real impact of sectarian polarization in the empire by comparing two contemporary Ottoman statesmen who belonged to Shia and Sunni sects of Islam as they governed their provinces in Syria. This kind of comparative studies of the Ottoman governors in terms of their distinct sect has been either not fully taken into consideration or totally ignored before. In the meantime, we shall also shortly explore how the Ottoman formidable enemies of the time interpreted the religious sectarianism and identity politics for the sake of their own security and interests.
School Leadership Challenges in Faroese Compulsory Schools During the COVID-19 Crisis / Avbjóðingar hjá skúlaleiðslum í føroyskum fólkaskúlum undir COVID-19 kreppuni
Authors: Vijayavarathan Kalpana
Published: November 2024

AbstractThis qualitative study was conducted to explore the impact of COVID-19 on Faroese school leadership with a view to identifying challenges faced by leaders and assessing the efficacy of their crisis leadership in enabling a positive learning-teaching environment. The findings indicated that the challenges comprised teacher self-efficacy issues in teacher ability to adopt Information Communication Technology (ICT) to fulfil student learning outcomes, ensuring student participation and safe learning environments, teacher and leader emotional/psychological burdens and hygiene logistics. Faroese crisis leadership exhibited proactive support for teachers, helped with online teaching, offered channels of open, meaningful communication, supported teachers through active listening, accepted teacher feedback, and showed an inclusive approach to managing teaching. School leaders appeared to have stepped up to the challenge despite the crisis testing the resilience of staff, students and themselves. They reflected on what COVID-19 has taught them and have grasped the significance of the human element in crisis management. The Faroese school system may require an established framework from the National Board of Education to cope with future crisis to ensure a responsive instead of a reactive approach to maintaining core competences of schools in a challenging environment.ÚrtakHenda kvalitativa kanningin varð gjørd  fyri at kanna ávirkanina av COVID-19 á føroyskar skúlaleiðslur við at eyðmerkja avbjóðingar hjá leiðarunum og meta um nýtsluna av leiðslu-hættum undir kreppu til at skapa eitt fremjandi undirvísingar- og læruumhvørvi.

Patulin removal in fruit-based products using probiotics and potential probiotics
Authors: Zoghi Alaleh
Published: November 2024

Patulin (PAT) is a prevalent mycotoxin frequently found in fruit and its derivatives, such as apple, pear, and juices. Despite worldwide attempts to diminish the levels of PAT at every stage of the fruit production process, its contamination rate remains high. This mycotoxin is worrisome due to its potential adverse impacts on human health. Eating PAT-contaminated fruit can lead to acute and chronic health issues. It is established, by the Joint FAO/WHO, a maximum tolerable daily intake for PAT at 0.4 µg/kg/day. Therefore, monitoring for PAT contamination is essential for the safe consumption of fruits and fruit-related products such as juices, purees, ciders, jams, marmalades, vinegar, and dried fruits. PAT has physiochemical properties that enable its survival in cold, hypoxic, acidic, or high-temperature conditions. Ideally, detoxification procedures should aim to reduce the level of toxins to safe levels whilst preserving the nutritional and palatable values of the treated commodity. There are several physical, chemical, and biological techniques available for PAT detoxification. However, while physical and chemical methods can remove PAT, they may also lower the nutrient quality and organoleptic properties of the food. Biological detoxification is an effective, environmentally friendly, easy, and cost-effective method, as established by existing research. It has proven efficacy in food safety research and regulatory compliance programs. Probiotics have been studied for their potential to reduce PAT in foods via different mechanisms (such as adsorption, degradation, and transformation), as well as all their health-beneficial effects. In this review, the reduction of PAT in fruit-based products using probiotics or potential probiotics is widely discussed.
“This house is so lonely!”: Home, Belonging, and Identity in Memoirs of Loss and Grief
Authors: Małecka Katarzyna A.
Published: November 2024

This analysis explores select autobiographical representations of relationships the bereaved develop with their surroundings in the context of a major death-related loss. After a significant loss, the concepts of home, belonging, and identity are redefined, and the grieving self needs to revise its assumptive worldview to adjust to these changes. Drawing parallels between bereavement research and grief memoirs, three main themes are analyzed: 1. How hitherto familiar spaces feel both welcome and unwelcome to the bereaved; 2. How loss influences culinary settings and domestic routines; and 3. How financial factors and relocation uproot the griever’s identity and sense of belonging.
Filling the Gaps in Broken Memory while Renewing the Cityscape: Navigating Belonging in Orhan Pamuk’s The Red-Haired Woman
Authors: Yılmaz Simge
Published: November 2024

The Red-Haired Woman, one of Orhan Pamuk’s post-Nobel novels, is a concise, fable-like narrative that delves into the complexities of father-son conflicts. The novel parallels the journey of the protagonist, Cem, with the broader socio-cultural context of modern Turkey. It highlights Cem’s struggle between two ideologically contrasting father figures and draws a compelling analogy between his fragmented memory and Turkey’s cultural memories influenced by both the East and West. This paper explores the application of various memory types in the novel, scrutinizes the reliability of its narrators, and analyzes the depiction of urban space in relation to both individual and national memory, with particular focus on the contractor protagonist.
Silent Voices: Dwelling with our Specters through Palimpsesto (2017), by Doris Salcedo
Authors: Gutiérrez Cajaraville Carlos , Calonge Conde Ana
Published: November 2024

A palimpsest is a writing erased and replaced by another. Sometimes, perhaps all too often, our lives become incarnated palimpsests thanks to the prevailing biopolitics, which refers not only to the government of the living, but also to the multiple practices of dying and disappearing. Can art teach us to create new spaces of co-habitation with our essential ghosts, with those who refuse to abandon us despite everything? In this article we address the work entitled Palimpsesto, in which the Colombian artist Doris Salcedo (Bogotá, 1958), makes visible one of the most ignominious events in our recent history: the deaths of thousands of people in the Mediterranean due to indifference and, on occasions, the complicity—conscious or unconscious—of a desensitized European society, closed in on itself. In Palimpsesto, the artist creates a space where those absences are permanently present in absentia. However, Salcedo’s art goes beyond testimony and representation: the tears that flow from the earth itself, outlining on the ground the names of women and men who drowned while fleeing war, reveal not only the need to name those who are no longer with us, but could lay the foundations to erect a kind of divinology (Meillassoux, “Deuil à venir” 105) through which new ties and forms of dwelling would be built, beyond interested political use, between human beings and those harassing absences.

Praca w sektorze nowych technologii? Kształcenie dla rynku pracy osób z niepełnosprawnościami
Authors: Żuchowska-Skiba Dorota , Gąciarz Barbara
Published: November 2024

W XXI w. zmiany gospodarcze przyczyniły się do wzrostu znaczenia sektora nowoczesnych technologii, szczególnie w obszarach IT, e-commerce, e-marketingu i projektowania UX. Rozwój tych branż wymaga specjalistycznej wiedzy z zakresu programowania, projektowania i wdrażania technologii, otwierając drzwi dla osób z różnymi niepełnosprawnościami. Nowe formy pracy, zwłaszcza praca zdalna oraz asystujące technologie, umożliwiają części osób z niepełnosprawnościami wykonywanie pracy na otwartym rynku. Wymaga to jednak uzyskania wykształcenia kierunkowego i zdobycia przez osoby z niepełnosprawnościami odpowiednich umiejętności i kompetencji. Takie możliwości oferuje szkolnictwo wyższe. W związku z tym chcemy zbadać, jak absolwenci pracujący w branżach związanych z nowymi technologiami oceniają działania i aktywności mające przygotować ich do pracy w tych branżach na ich uczelniach.
Badanie objęło 11 absolwentów z niepełnosprawnościami i pokazało, że ważne jest dalsze wsparcie programów edukacyjnych, ale też istotne znaczenie ma ułatwianie kontaktu pracodawcom z osobami z niepełnosprawnościami, co pozwala na wzajemne poznanie i może przyczynić się do budowania bardziej dostępnego środowisko pracy dla takich osób.
Sztuka jako praca: o profesjonalności i profesjonalizacji artystów i artystek z niepełnosprawnością wzroku w Meksyku
Authors: Dubiel Monika
Published: November 2024

Przedmiotem mojego zainteresowania jest działalność artystyczna osób z niepełnosprawnością wzroku (głównie aktorów i fotografów, ale także muzyków czy pisarzy) w Meksyku. Celem artykułu jest ocena tej aktywności rozumianej jako praca zawodowa. Główny problem badawczy postawiony w niniejszym artykule sprowadza się do pytania: kto lub co decyduje, iż ktoś może być nazwany artystą profesjonalnym. Artykuł napisany został na podstawie wyników badań jakościowych, które prowadziłam w tym środowisku w latach 2019–2022. W badaniu wykorzystane zostały różne techniki badań etnograficznych ze szczególnym naciskiem na wywiad uzupełniony o obserwację uczestniczącą i nieuczestniczącą. Wyniki wskazują, że dla analizowanego problemu najistotniejsze są dwa wyróżniki pracy zawodowej: wynagrodzenie i doświadczenie. Kluczowa do definiowania siebie lub kogoś jako artysty czy artystki okazuje się kategoria uznania, w swoisty sposób konstruowana w obu wspomnianych aspektach.
Rozważania moje są osadzone w paradygmacie studiów o niepełnosprawności. Silnie są również zakorzenione w lokalnym kontekście meksykańskim.
Aktywność prozawodowa uczestników warsztatów terapii zajęciowej – szanse, wyzwania i dylematy
Authors: Kocejko Magdalena , Greniuk Angelika
Published: November 2024

Konwencja o prawach osób niepełnosprawnych wskazała nowe kierunki działań dotyczących aktywizacji zawodowej osób z niepełnosprawnościami. Skoncentrowanie na otwartym rynku pracy stawia pytania o rolę takich placówek, jak warsztaty terapii zajęciowej (dalej: WTZ) i wymaga określenia nowego sprofilowania działania tych podmiotów także w obszarze wspierania aktywności prozawodowej ich uczestników. W odpowiedzi na potrzebę określenia i doprecyzowania kierunków działań w tym zakresie w ramach systemowego projektu „Aktywni niepełnosprawni – narzędzia wsparcia samodzielności osób niepełnosprawnych” wypracowane zostały nowe „Standardy funkcjonowania Warsztatów Terapii Zajęciowej”.
Celem artykułu jest zaprezentowanie wyników prowadzonych przez autorki badań ewaluacyjnych pilotażu wdrażania standardu w WT Z. Pokazano liczne uwarunkowania skuteczności działań z tym związanych. Mają one charakter zarówno zewnętrzny, jak i wewnętrzny. Wyniki prezentowanych badań mogą być przyczynkiem do dalszej dyskusji nad faktycznym miejscem WTZ w systemie aktywizacji zawodowej osób z niepełnosprawnościami z uwzględnieniem kierunków wynikających z konwencji. W artykule zaprezentowano niepublikowane wyniki badań ewaluacyjnych pilotażowego wdrażania standardów w WT Z przeprowadzonych w latach 2022–2023 w 72 wybranych warsztatach na terenie całego kraju. Badanie ewaluacyjne prowadzone były na zlecenie Polskiego Stowarzyszenia na Rzecz Osób z Niepełnosprawnością Intelektualną.
Aktywność zawodowa osób z niepełnosprawnościami w kontekście modeli niepełnosprawności
Authors: Maciąg Rafał
Published: November 2024

W Polsce notuje się dość niskie wskaźniki aktywności zawodowej oraz zatrudnienia osób z niepełnosprawnościami w porównaniu do innych krajów europejskich. Celem artykułu jest wskazanie przyczyn niskiego wskaźnika aktywności zawodowej w kontekście teoretycznych modeli niepełnosprawności. W społeczeństwie dominują postawy przychylne wobec zabezpieczeń społecznych, w tym skłaniające się ku pozostawaniu na rencie. System orzecznictwa lekarskiego jest skupiony na medycznej ocenie funkcji organizmu, co nie sprzyja kierowaniu do pracy, a system rehabilitacji jest rozproszony i nieczytelny dla beneficjentów. Z badań wynika, że system aktywizacji zawodowej wspierany przez Państwowy Fundusz Rehabilitacji Osób Niepełnosprawnych nie spełnia pokładanych w nim oczekiwań. Utrzymuje się tradycyjny model indywidualny (medyczny) niepełnosprawności, ugruntowany przez rodzinną opiekę nad osobą z niepełnosprawnością. Międzynarodowa Klasyfikacja Funkcjonowania, Niepełnosprawności i Zdrowia (ICF), która jest narzędziem przydatnym w ocenie zdolności do pracy w wielu krajach i regionach, w Polsce nie jest wdrażana. W celu zachęcenia do zmian wśród decydentów, lekarzy i pracodawców potrzebna jest szersza dyskusja nad wykorzystaniem procedur niezbędnych do oceny potencjału osób z niepełnosprawnościami.
Mobbing i dyskryminacja osób z niepełnosprawnościami w sferze zawodowej
Authors: Chmurska Edyta
Published: November 2024

W artykule przedstawiono wybrane problemy. Autorka przytoczyła definicje oraz atrybuty mniejszości, aby zobrazować miejsce osób z niepełnosprawnościami w społeczeństwie. Są one częścią populacji i mają swoje potrzeby tak jak wszyscy inni ludzie. W swoim życiu wskazują oni na bardzo duże znaczenie pracy, która nie tylko pozwala zaspokoić potrzeby materialne, ale przede wszystkim wspomaga rehabilitację zawodową. Podejmowana przez osoby z niepełnosprawnością praca w ramach rehabilitacji zawodowej powinna uwzględniać ograniczenia i uwarunkowania wynikające z ich aktualnego stanu zdrowia. Aktywność zawodowa osób z niepełnosprawnością jest promowana przez media w formie kampanii społecznych, jednak pomimo usilnych starań nie przynosi to oczekiwanych rezultatów. Należy zauważyć, iż osoby z niepełnosprawnościami same sobie stawiają bariery w drodze do zatrudnienia, a także są im one stawiane przez pracodawców. Ponadto są też one często ofiarami wykorzystywania, mobbingu i dyskryminacji ze strony pracodawców, o czym świadczą przedstawione w artykule wypowiedzi.

Relevance. Negative impact of waste from mining enterprises on the ecological state of the surrounding areas. Aim. To determine the migration ability of toxic chemical elements from waste storage sites of the Ermakovskoe beryllium deposit in the air. Object. Ermakovskoe fluorite-bertrandite-phenacite deposit and the surrounding area. Methods. Inductively coupled plasma mass spectrometry, laser diffraction, inductively coupled plasma atomic emission spectrometry. Results and conclusions. The paper introduces the experimental studies of surface atmospheric pollution by mining waste from the Ermakovskoe fluorite-bertrandite-phenakite deposit are presented using an installation for collecting aerosols above the sand surface. It was established that toxic components formed during the decomposition of residual sulfide mineralization and products of the interaction of acidic waters with rocks move from the sand thickness to the surface along with water vapor. The moisture condensed over the sand contains high contents of aluminum, iron, manganese, zinc, and phosphorus. These elements form a halo of air pollution over mining waste and are then dispersed by air currents into the surrounding area. In winter, due to wind dispersion of aerosols, the snow cover becomes contaminated over a vast area. Among the toxic elements found were beryllium, lead, cadmium, and molybdenum, which belong to the second hazard class. The solid residue of the snow cover contains a fine fraction of dust, the size of which is less than 10 microns. The halo of snow contamination with toxic chemical elements and dust extends several kilometers away from the disturbed lands.
Increasing the operating time of pumping units of water-reducing wells through the use of self-cleaning filters
Authors: Shishlyannikov Dmitry I. , Kartavtsev Vadim K. , Sitnikov Dmitry A. , Korotkov Yuri G. , Ivanchenko Anna A.
Published: November 2024

Relevance. At enterprises engaged in open-pit mining, water-reducing wells equipped with submersible installations of electric submersible pumps are widely used in drainage systems. A significant content of particles of mechanical impurities in the pumped-out well fluid causes intense hydro-abrasive wear of the working stages of the electric submersible pumps. Among the existing methods of combating hydro-abrasive wear of submersible pumps in water-reducing wells, the simplest, most economical and effective is the use of filters of various designs. An urgent task is to increase the operating time of submersible electric submersible pumps while reducing the time and costs for cleaning or replacing filters. Aim. Justification of the designs and operating parameters of a self-cleaning filter and tubing string extension included in the electric submersible pump assembly of a dewatering well. Methods. Static calculations of deformation of the tubing column and the tubing column extension under the influence of overpressure. Results and conclusions. The authors have carried out the analysis of an electric submersible pump functioning in the dewatering wells of quarries during the development of mineral deposits by the open method. It was revealed that the main reason for the failure of the electric submersible pumps is the hydro-abrasive wear of the working stages of the submersible pump. The authors propose a method to increase the operating time of the electric submersible pumps in dewatering wells complicated by intensive removal of particles of mechanical impurities by using a self-cleaning filter of the original design. It is noted that a promising direction of development of the drive for self-cleaning filters is the use of deformation of the tubing column. Based on the calculations carried out, it was concluded that the small depths of dewatering wells cause an insufficient amount of deformation of the tubing string to clean the filter element. To increase the length of the reciprocating movement of the electric submersible pumps relative to the production string of a dewatering well, it is proposed to use a tubing string extension of an original design. The operating parameters of the tubing string extension were calculated, which showed the possibility of providing the required amount of controlled reciprocating movement of the electric submersible pumps in the well to restore the throughput of a self-cleaning filter.
Synthesis of Magnéli phases in a high-speed electric discharge plasma jet

Published: November 2024

Relevance. Currently, there is an active search for photocatalytic materials suitable for water decomposition and hydrogen production that exhibit activity when exposed to visible light, and are also accessible, chemically stable and safe. In this regard, a number of materials with the general formula TinO2n-1 (n=2–10) are distinguished, they are called Magnéli phases. Despite the fact that Magnéli phases exhibit significantly higher photocatalytic activity compared to traditional titanium oxides (rutile, anatase, brookite), their practical application is currently extremely difficult due to the complexity of their synthesis. Promising approaches are those that provide well-controlled conditions with the possibility of rapid stabilization of the system, among which plasma synthesis methods stand out. Aim. To develop a method for synthesizing a product containing Magnéli phases in a high-speed jet of electric discharge plasma. Objects. Dispersed materials obtained in the Ti-O system. Methods. Plasma dynamic synthesis, X-ray diffractometry (X-ray phase analysis), scanning electron microscopy, transmission electron microscopy. Results. Using a high-speed jet of electric discharge plasma generated by a coaxial magnetoplasma accelerator, experimental studies were performed on the synthesis of non-stoichiometric titanium oxides in a carbon dioxide environment. The composition and microstructure of the obtained dispersed products were studied. It was revealed that the materials contain Magnéli phases TinO2n−1, as well as traditional stoichiometric rutile and anatase. From the point of view of the efficiency of obtaining Magnéli phases, the single-pulse mode of operation is more attractive (content over 50%), while the efficiency of CO2 conversion is higher in the multi-pulse mode (up to 10% of CO2 is converted into CO). A distinctive feature of the synthesized materials at both the micro- and nanolevels is the tendency to form particles with a high degree of sphericity. The nanofraction of the products mainly consists of rounded particles with sizes up to hundreds of nanometers, of which the Magnéli phases primarily include nanoparticles with a characteristic highly defective crystalline structure with dislocation shifts.

Currently, when using submersible electric motors in centrifugal electric pump installations in cyclic operation mode, there is a reduction in the inter-repair period of submersible equipment, which is associated with a reduction in oil pumping periods to several minutes. As a result, there is a multiple increase in starting currents and torque, which leads to an increase in mechanical loads on the pump shaft and appearance of resonance phenomena during the electric motor acceleration, reducing the reliability of a seal protection. To solve these problems, it is necessary to synthesize closed-loop vector control systems with current and electromagnetic torque control in transient responses. Open-loop scalar control systems for electric drives of oil well production are used in operation, which is due to the complexity of obtaining feedback signals on the angular velocity of the rotor and the moment of resistance on the shaft by means of submersible telemetry. This problem determines the relevance and necessity of developing observers for rotor speed and load torque estimation, taking into account the features of the technological process of installing centrifugal electric pumps, in particular, the presence of a long cable for powering a submersible electric motor based on a synchronous machine with permanent magnets. Aim. To develop a full-order observer rotor speed and load torque for the dynamic system "long supply cable – synchronous motor with permanent magnets". Methods. System analysis and identification of dynamic systems, synthesis of Luenberger observers, mathematical modeling of dynamic systems, electric drives and electrical machines. Result and conclusions. The authors have proposed the mathematical model of a rotor speed and load torque full-order observer for the dynamic system "long supply cable – synchronous motor with permanent magnets". The performance of the observer was investigated under varying load on the shaft, mismatch of non-zero initial conditions, deviation of the parameters of the equivalent circuit of the observer and the object in the range from –20 to +20% of the nominal values.

Speaking skill is a language ability in pronouncing articulation sounds or uttering words to express thoughts, opinions, and feelings to other people as speakers. Language errors are the use of speech forms of various linguistic units which include words, sentences, paragraphs, which deviate from the system of language rules. Many of the students from Darul Hijrah Islamic boarding School experienced language errors in using Arabic as their daily language. The purpose of this research is to find out the form of errors and factors that cause language errors in students' speaking skills. This research is a qualitative research using a descriptive analysis approach. Data collection techniques were carried out using observation, interviews, and documentation. The subjects of this study were old students and language supervisors at Darul Hijrah Islamic boarding School. Based on the results of the study, linguistic errors in daily conversations made by students of  Islamic boarding School are divided into 7 forms of errors, namely errors in adding letters outside of Arabic, using repeated words, question words, the word "فقط", pronouns, everyday expressions, and Arabic vocabulary. The factors that cause language errors are classified into two parts. Internal factors are; lack of vocabulary, not writing vocabulary, lack of awareness of the importance of language, because of local culture and language, interference of foreign languages in Arabic, due to lack of interest in learning Arabic, often using local languages, do not know vocabulary and do not understand Arabic grammar, not serious about learning Arabic, unable to pronounce Arabic letters. External factors are; Errors in the process of distributing vocabulary both orally and in writing and bad associations among students.

Ergonomi bermanfaat untuk meningkatkan keselamatan kerja dan produktivitas karyawan. Pekerjaan yang tidak dilakukan sesuai prinsip ergonomi akan menimbulkan berbagai masalah kesehatan yang akan merugikan pekerja dan organisasi. Edukasi program ergonomi dinilai efektif dalam mengurangi masalah kesehatan akibat pekerjaan terutama di bidang konstruksi sehingga hal ini diharapkan menciptakan perilaku serta budaya kerja yang aman. Pekerja di warehouse dan di kantor berisiko mengalami gangguan otot, sendi, dan tulang akibat pola gerak yang tidak ergonomis. Para pekerja yang belum pernah menerima edukasi panduan ergonomi dan skrining kesehatan serta K3 yang belum terselenggara menjadi perhatian bagi tim PKM. Adapun tujuan dari kegiatan ini adalah untuk mengetahui status kesehatan dan meningkatkan pengetahuan para pekerja mengenai ergonomi di lingkungan kerja. Kegiatan edukasi panduan ergonomi terdiri dari pemaparan materi, demonstrasi, pemberian poster, pelaksanaan pre-test dan post-test, serta pemeriksaan kesehatan. Hasil yang didapatkan adalah terjadi peningkatan nilai rerata post-test sebesar 2.74 apabila dibandingkan dengan nilai rerata pre-test. Selain itu, setelah edukasi terjadi peningkatan nilai minimum dari 25 pada pre-test menjadi 50 pada post-test. Sebagian besar peserta pemeriksaan kesehatan berada dalam kategori obesitas (47%). Hal ini menjadi masukan serta bahan pertimbangan bagi mitra dalam pengambilan keputusan untuk keselamatan karyawan dan efisiensi perusahaan.
