Authors: Pham Thanh , Nguyen Thanh Binh , Ha Son , Nguyen Ngoc Ngoc Thanh
Published: December 2023

This research explored the potential of artificial intelligence (AI)-assisted learning using ChatGPT in an engineering course at a university in South-east Asia. The study investigated the benefits and challenges that students may encounter when utilising ChatGPT-3.5 as a learning tool. This research developed an AI-assisted learning flow that empowers learners and lecturers to integrate ChatGPT into their teaching and learning processes. The flow was subsequently used to validate and assess a variety of exercises, tutorial tasks and assessment-like questions for the course under study. Introducing a self-rating system allowed the study to facilitate users in assessing the generative responses. The findings indicate that ChatGPT has significant potential to assist students; however, there is a necessity for training and offering guidance to students on effective interactions with ChatGPT. The study contributes to the evidence of the potential of AI-assisted learning and identifies areas for future research in refining the use of AI tools to better support students' educational journey.

Whether high‐intensity exercise training and detraining combined with skeletal muscle pump (MP) could alter the magnitude of postexercise hypotension has not been investigated. We therefore sought to determine whether the combination of MP (unloaded back‐pedaling) with 4 weeks of high‐intensity exercise training and detraining could alter the magnitude of postexercise hypotension. Fourteen healthy men underwent 4 weeks of high‐intensity exercise training (5 consecutive days per week for 15 min per session at 40% of the difference between the gas exchange threshold and maximal oxygen uptake [i.e., Δ40%]) followed by detraining for 4 weeks. Assessments were conducted at Pre‐training (Pre), Post‐training (Post) and after Detraining with (MP) and without MP (Con). The exercise test in the Pre, Post and the Detraining consisted of 15 min exercise at Δ40% followed by 1 h of recovery. At all time‐points, the postexercise reduction in mean arterial pressure (MAP) was reduced in MP compared to Con (all p < 0.01). Four weeks of high‐intensity exercise training resulted in a reduction in the magnitude of postexercise hypotension (i.e., the change in MAP from baseline was mitigated) across both trials (All p < 0.01) when compared to Pre and Detraining. Following Detraining, the reduction of MAP from baseline was reduced compared to Pre, but was not different from Post. We conclude that high‐intensity exercise training combined with skeletal MP reduces the magnitude of postexercise hypotension, and this effect is partially retained for 4 weeks following the complete cessation of high‐intensity exercise training.

Published: December 2023

The water uptake behavior of Wood Dust (WD)/Prosopis Juliflora Fiber (PJF)/Phenol-Formaldehyde (PF) hybrid composites which are immersed in distilled and seawater environments was evaluated. Three different composite samples were fabricated by reinforcing WD and PJF with PF resin. The fabricated specimens were immersed in sea and distilled water to note down the moisture content absorption of the specimens for different time intervals from 0 to 240 h. The dry and wet specimens underwent mechanical properties testing as per ASTM standards and the findings for wet and dry specimens have been compared and analyzed. It is observed that the specimens which are immersed in sea (salt) water absorb more moisture content than the specimen immersed in distilled water and the PJF-rich (30 wt% of PJF & 10 wt % of WD) specimen absorbs more water than the other specimens. The water uptake behavior of the WD/PJF/PF hybrid composite follows a non-Fickian behavior. The mechanical performance (tensile, flexural, and impact) of the 10 wt % of WD 30 wt % of PJF specimen was better than that of other specimens at dry (before immersion) conditions and lost strength when immersed in sea and distilled water. SEM analysis was also done on the broken surface of the tested specimens which were exposed to the water environment.

Published: December 2023

Fe3O4 nanoparticles were prepared by chemical co-precipitation, modified with dextran, and dispersed in water to form a magnetic fluid (MF) for use in biomedical areas. The analyses of stability and magnetic property demonstrate that the prepared functional MF possesses outstanding stability (stability index within 60 days, high dilution stability, and autoclaved stability) and high magnetization (the values χ and M

s
of MF are 5.87 × 10−4 and 20.57 emu/g, respectively). Due to the coating of dextran, the toxicity of MF is minimal (in vitro survival rate of MCF-7 cells, blood compatibility, and in vivo toxicity). In addition, although the outer layer is coated with dextran, the M

s
intensity remains high, so the Fe3O4 MF owns a fast magnetic temperature response (when the MF concentration is 55 mg/mL, it can rapidly rise to 55°C within 800 s), which plays an extremely vital role in MF hyperthermia. So, the MF can effectively cause necrosis of human lung A549 cells, which shows a certain application potential.

Published: December 2023

In this study, the properties of seawater volcanic scoria aggregate concrete (SVAC)-filled circular stainless steel (SFCST) and glass fibre-reinforced plastic (GFRP) tubes (SFCGT) were investigated. Ten groups were considered and 30 specimens were prepared, including four different parameters: the concrete type (SVAC and ordinary concrete [OC]), outer tube type (GFRP and stainless steel tubes), concrete strength (C30 and C40), and tube thickness (0, 3, and 4 mm). The typical influences of the SVAC and outer tube on the mechanical properties of specimens were then analysed. The research findings show that the strength and ductility of the SFCGT and SFCST are significantly higher than those of plain SVAC. The peak strain and strength enhancement factor of the SFCGT and SFCST increase with an increase in the tube thickness, and the concrete strength has a detrimental impact on the toughness of the specimen. Unlike in the confined OC specimens, a sudden decrease is observed in the stress–strain curves of the SFCGT and SFCST owing to the changes in the deformability of the SVAC. Generally, the strengths of the SFCGT and SFCST specimens are 10.3% lower and 4.1% higher than those of the confined OC specimens, respectively. Finally, analytical models of the strength and stress–strain curves considering the influences of the SVAC and passive confinement were established, and numerical simulations were performed to provide a basis for the practical application of the SFCGT and SFCST.

Ką mums gali pasakyti Mindaugo dovanojimas vyskupui Kristijonui? Apmąstymai galimos polemikos fone | The Donation of King Mindaugas to the Lithuanian Bishop Christian: Considerations on a Possible Controversy
Authors: Jankauskas Vytas
Published: December 2023

The Christianisation of Lithuania is usually dated to the late 14th and early 15th centuries, but the first attempt to turn Lithuania into a Christian kingdom was made by Mindaugas. In 1251 he was baptised by the Master of Livonia Andreas de Velven (also known as von Stirland), and in 1253 was crowned King of Lithuania with the support of Pope Innocent IV. Christian (Kristijonas), the Livonian priest who taught the ruler the virtues of Christianity, a member of the Teutonic Order, became the first Bishop of Lithuania at Mindaugas’ request. It is known that Mindaugas bequeathed several lands to Christian in 1254. The article examines the background to this act of providing for the Diocese of Lithuania. The author argues that the donation of the possessions to Christian is the most important source that can help identify Mindaugas’ own domain. He hypothesises that Mindaugas’ domain may have been located south of the lands donated to Bishop Christian, in an area known in historiography as the defence line of the lower River Nemunas. In his analysis of this hypothesis, the author presents arguments that invite us to reconsider the established assertion in historiography that the domains of the senior dukes could have been located in present-day east Lithuania.
Monuments, Memories, and Conversion: Commemorating Saint Louis of France in Colonial Carthage
Authors: Coslett Daniel E.
Published: December 2023

Although scholars have explored the colonialist nature of archaeology and the importance of antiquity in the legitimation of modern empires, accounts of French-occupied North Africa have largely overlooked the place of medievalism in the nineteenth- and twentieth-century French colonial project. Illustrating the strategic importance of references to the crusader-king Louis IX, whose short stay in Tunisia culminated in his death in 1270, this article explores a dynamic ensemble of commemorative structures and spaces built by France and the Catholic Church on the Byrsa Hill, Carthage’s ancient acropolis. It considers a Gothic Revival chapel (1841), a scholasticate and antiquities museum (1879), an eclectic cathedral (1894), and an archaeological garden (1950–56) before concluding with a brief account of the site’s postcolonial development and current state. The conversion of the Byrsa by Catholic officials demonstrates the multifaceted nature of colonial mythologizing and architecture, where both antiquity and medievalism played critical sociopolitical roles.
White Supremacist and Racist Opinion in America 1940s–2018
Authors: Smith Robert C. , Seltzer Richard , Best Ayana
Published: December 2023

Since the 2008 presidential election of Barack Obama the United States has seen a significant increase in white supremacist and overtly racist attitudes. The rise of the Tea Party in 2009 and numerous other Alt-right conservative movements seemed to foreshadow the election of a presidential candidate like Donald Trump. During his presidency, Donald Trump was arguably the first openly white supremacist and racist president since Woodrow Wilson. He referred to Black Americans as lazy, and Mexicans as rapists and spewed anti-Asian rhetoric throughout his speeches. This paper examines how white supremacist and racist attitudes have changed over time. Using the American National Elections Survey (ANES) and the National Opinion Research Center (NORC) survey data from the 1940s through 2018, we descriptively show the salience of white racist attitudes and their effect on the 2016 presidential election.
The Paradox of Visibility
Authors: Shorbagy Manar
Published: December 2023

Black America is not present, as it should be, in the literature on US soft power. This paper argues that Black culture exerts a powerful positive attraction abroad. This attraction, grounded in the forms of Black resistance to racial injustice, leads to a reconceptualization of America’s identity, by foreign audiences. A counter claim of what counts as “America” takes shape. The rethinking of America’s identity abroad responds to the appeal of the legacy of Black resistance. However, Black culture is, more often, unavailable to policymakers for garnering desired outcomes. Incorporating Black culture into the study of soft power helps sharpen the concept’s definition and points to when and why some forms of soft power are unavailable to decision makers.

Published: December 2023

Introduction. Inclusive education is a collective responsibility for all stakeholders in the educational process, with particular emphasis on the role of principals. Principals, through their management practices, bear the responsibility of fostering educational centers that uphold the principles of justice, equality, and equity from a holistic perspective. Aim. This study aims to analyze the personal and professional profiles characterizing school principals in Costa Rican public elementary schools. Method. The research, qualitative in nature, employed a multiple case study approach involving six school principals. Data were collected through in-depth, semi-structured interviews, and processed using Atlas.ti v.8 software. Mixed coding was employed for each analysis. Results. The findings reveal that the profile of school principals comprises two key areas. The first pertains to training factors, professional development, and job stability. The second corresponds to intrinsic individual factors such as vocation, values, mentors, and experience. Discussion. The results show minimal or no professional development attributed to limitations within the educational system in terms of updating processes on inclusive education. Conversely, the outcomes in the second area of the profile are associated with values and experiences that strengthen inclusive practices in the educational management of the center. The results are useful because they enable decision-making at the school level to strengthen actions that promote inclusive education through a “school for all” approach within the educational management.

Published: December 2023

Purpose. This study aimed to establish the association between perceptions of formative competency assessment and the satisfaction level with the virtual courses based on sex and career level of university students in Costa Rica. Methodology. Six courses were selected for the study by convenience, with a sample of 127 students (61.35%) of 207 students enrolled in the first semester of 2021. Data collection utilized items from the Questionnaire on Methodology and Assessment in Physical Education Initial Training (QMAPEIT). Each student provided voluntary consent to participate; then the survey was administered in-class (synchronously) within a virtual environment. Results. The chi-squared analysis revealed a significant statistical difference by sex in the perception of the competence learning process when the formative assessment was used (χ2= 6.69, p= 0.035). Additionally, differences were observed in the perception of skill acquisition for their personal and professional life (χ2= 6.562, p=0.038), and in the level of general satisfaction with the course (χ2= 6.427, p= 0.040). Regarding the career level, a statistically significant difference was found between variables (p= 0.039). Conclusions. The findings of this research contribute to ongoing reflection, understanding, and improvement in the evaluation processes. This facilitates better quality of teaching and learning based on the differences in perception between men and women and their university career levels.

Endoscopic Ultrasound Biliary Drainage in Pancreatic Cancer
Authors: Lau Kar Wai , Rimbaș Mihai , Tripodi Giulia , Larghi Alberto
Published: December 2023

Endoscopic ultrasound (EUS) guided biliary drainage (BD) is an accepted salvage procedure in patients with distal malignant biliary obstruction (DMBO) when endoscopic retrograde cholangiopancreatography (ERCP) is unsuccessful. The potential advantages of EUS-BD include gastric or duodenal biliary access, utilization of novel biliary stents and stent placement away from the area of stenosis, resulting in longer stent patency. These features make EUS-BD very appealing as a primary procedure for biliary drainage. There is a growing body of evidence supporting the utilization of EUS as a primary drainage procedure instead of ERCP, with comparable outcomes.
Microscopic Colitis: A Diagnostic Challenge in Patients with Irritable Bowel Syndrome
Authors: Rusu Flaviu , Caragut Roxana Luiza , Lorena Mocanu Camelia , Leucuta Daniel Corneliu , Dumitrascu Dan Lucian
Published: December 2023

Background and Aims: Irritable Bowel Syndrome (IBS) is one of the most frequently diagnosed gastrointestinal disease with a prevalence of 4.1% in the general population. It is diagnosed using the Rome IV criteria. Microscopic colitis (MC), collagenous/lymphocytic colitis is a cause of chronic, watery, non-bloody diarrhea. It is a real challenge to diagnose MC in patients with IBS. The aims of the study were to determine the prevalence of MC in patients initially diagnosed with IBS, as well as to correlate fecal calprotectin levels with the endoscopic findings and microscopic inflammation in MC.

Methods: This is a retrospective study conducted in a single tertiary center with over 89 IBS patients for a period of 4 years. The patients included were patients diagnosed with IBS predominant diarrhea (IBS-D) and mixed IBS (IBS-M) using the Rome IV criteria. Total colonoscopy was performed in these patients, multiple biopsies being taken and calprotectin levels were measured.

Results: Out of a total of 89 IBS-D patients, 58 patients (65.2%) had no microscopic lesions, 12 patients (13.5%) had diverticular disease, 9 patients (10.1%) had non-specific chronic inflammation of the colon mucosa and 10 patients (11.2%) were diagnosed with MC. The calprotectin levels ranged from 49 μg/g to 213 μg/g. Of a total of 10 patients diagnosed with MC, 6 (60%) of them had calprotectin levels <100 μg/g and 4 (40%) had calprotectin levels >100 μg/g. The fecal calprotectin levels were higher in patients diagnosed with MC compared to those who had no microscopic lesions at the histological exam and it was also correlated with the grade of colonic microscopic inflammation.

Conclusions: Microscopic colitis is less familiar to physicians and can be clinically misdiagnosed as IBS-D. An early and correct diagnosis is important for an accurate therapy.

Background and Aims: International guidelines advise improving esophagogastroduodenoscopy (EGD) quality in Western countries, where gastric cancer is still diagnosed in advanced stages. This nationwide study investigated some indicators for the quality of EGD performed in endoscopic centers in Italy.

Methods: Clinical, endoscopic, and procedural data of consecutive EGDs performed in one month in the participating centers were reviewed and collected in a specific database. Some quality indicators before and during endoscopic procedures were evaluated.

Results: A total of 3,219 EGDs performed by 172 endoscopists in 28 centers were reviewed. Data found that some relevant information (family history for GI cancer, smoking habit, use of proton pump inhibitors) were not collected before endoscopy in 58.5-80.7% of patients. Pre-endoscopic preparation for gastric cleaning was routinely performed in only 2 (7.1%) centers. Regarding the procedure, sedation was not performed in 17.6% of patients, and virtual chromoendoscopy was frequently (>75%) used in only one (3.6%) center. An adequate sampling of the gastric mucosa (i.e., antral and gastric body specimens) was heterogeneously performed, and it was routinely performed only by 23% of endoscopists, and in 14.3% centers.

Conclusions: Our analysis showed that the quality of EGD performed in clinical practice in Italy deserves to be urgently improved in different aspects.
Anastomotic Leakage after Gastrectomy for Gastric Cancer
Authors: Seicean Radu Ion , Puscasu Danusia , Gheorghiu Andrei , Pojoga Cristina , Seicean Andrada , Dindelegan George
Published: December 2023

Anastomotic leakage (AL) constitutes a prominent cause of significant morbidity following gastrectomy for gastric cancer. The manifestation of AL typically occurs within 7 to 10 days post-surgery, with reported incidence rates of 5.8-6.7% for open gastrectomy and 3.3-4.1% for laparoscopic gastrectomy. Various predisposing risk factors have been identified, including the individual nutritional status (excluding obesity) and preoperative corticotherapy. Interestingly, the administration of neoadjuvant therapies appears to reduce the AL occurrence. In the context of distal gastrectomies, the rates of AL are comparable between laparoscopic, robotic, and open approaches. The total gastrectomies have higher AL rate compared to distal gastrectomies, which are considered the preferred approach. Prophylactic drainage measures have not demonstrated efficacy in preventing AL. As for postoperative management, conservative treatment is indicated for patients presenting with mild clinical symptoms and increased inflammatory blood tests. This approach involves fasting, enteral or parenteral nutrition, administration of antibiotics, and percutaneous drainage. For small AL, endoscopic therapies such as stents, vacuum therapy, clips, suturing devices, and injections are appropriate treatment options. In cases of high-volume fistulas, severe sepsis or failure of previous therapies, surgical reoperation becomes the ultimate solution.

Authors:   National Technical University of Ukraine “Igor Sikorsky Kyiv Polytechnic Institute”, Ukraine, GOLEMBIOVSKA O. I.
Published: December 2023

The article examines the multifaceted mechanisms underlying the antiviral activity of flavonoids, compounds widely distributed in the plant kingdom. The aim of the work was to review literature data on mechanisms of antiviral activity of flavonoids. Methods. Publications were selected based on the PubMed (https://pubmed.ncbi.nlm.nih.gov/) databases published in 2015–2023. They include information on mechanisms of antiviral activity of flavonoids. Results. Beginning with an overview of flavonoid structures, the document navigates through the intricate interactions between flavonoids and various stages of the viral life cycle. Drawing upon a comprehensive analysis of in vitro and in vivo studies, the review highlights the diverse ways in which flavonoids inhibit viral entry, replication, and release. Depending on their antiviral mechanisms, flavonoids can serve as preventive inhibitors, therapeutic inhibitors, or indirect inhibitors by influencing the immune system. Conclusion. The synthesized information not only contributes to the advancement of antiviral research but also lays the foundation for the development of novel therapeutic interventions against a spectrum of viral infections.

Vibration loads on the launch vehicle and spacecraft can reach a high level, leading to abnormal and emergency situations. Therefore, the spacecraft structure must not only support the payload and subsystems of the spacecraft but also have sufficient strength and rigid- ity to exclude any emergencies (damage, destruction, unwanted deformations of the structure, failure and failure of instruments and equipment) that may interfere with the success of the mission. The article aims to analyze the state of research on the design of vibration protection systems for spacecraft launched into working orbits by modern launch vehicles. The results of this analysis will contribute to the development of fundamental schemes of vibration protection systems and methods for effectively suppressing spacecraft spatial vibrations. It is shown that the development of new promising vibration protection systems will take place in the following directions: increasing the frequency range and damping parameters of the dynamic coupled system of “spacecraft and vibration isolation system”; changing approach to vibration suppression of the entire spacecraft (as a whole unit) to setting up the system for damping individual (the most re- sponsible and vibration-sensitive) spacecraft; the use the spacecraft active vibration suppression system in combination with a passive vibration protection system; use of schematic diagrams of spacecraft vibration protection systems with the introduction of hydraulic, electromagnetic and mechanical functional elements in order to increase the efficiency of vibration isolation systems; active suppres- sion of random vibrations in outer space during the operation of various spacecraft systems (due to disturbances from engines of orbit correction systems, etc.); using the adapter structure to perform the functions of a passive vibration protection system of the spacecraft.
THE USE OF DAIF HADITHS ON VIRTUES OF DEEDS (FAḌĀʾIL AL-AʿMĀL) IN ISLAMIC PREACHING: STUDY OF SOME MAJELIS TAKLIMS IN SOUTH TANGERANG

Published: December 2023

This article describes the use of daif hadiths about the virtues of deeds (faḍāʾil al-aʿmāl) used by preachers at four majelis taklims in South Tangerang-Banten. This article is a qualitative, descriptive, and analytic study. This study found that the majority of preachers delivered their preaching regarding the virtues of deeds (faḍāʾil al-aʿmāl) by presenting daif hadiths. They stated that daif hadiths may motivate jemaat (congregations) to do various good deeds as long as they do not contradict the Quran and ṣaḥīḥ hadiths. However, one majelis taklim refuses to use daif hadiths, even for the theme of virtues of deeds, and only uses ṣaḥīḥ hadiths in lectures for its congregation (jemaat).
Interpretasi Keluarga Ideal Perspektif Buya Hamka dan M. Quraish Shihab
Authors: Nisa Hafidzotun
Published: December 2023

This article explains the concept of the ideal family contained in the interpretations of al-Azhar by Hamka and al-Misbah by Muhammad Quraish Shihab. These two interpretations show that the Qur'an contains instructions that can be used as a benchmark for humans to achieve the ideal family, namely humans must always present feelings of sakinah, mawaddah, and rahmah in their family. Apart from that, they also have to protect each other from things that can lead them to the fires of hell, wishing each other well. The views of the two interpretations are very relevant to modern life, that the values of the Koran must exist in the family to achieve an ideal family. The method used in this study is descriptive-qualitative using the interpretations of al-Azhar and al-Mishbah as data sources by limiting them to surah al-Rūm 21, QS. al-Taḥrīm 6 and QS. al-Furqān 74. The views of the two interpretations are compared, then enriched by the views of other commentators and figures.

This article aims to determine the contribution of orientalists to contemporary hadith studies in Indonesia, map developing theories, identify the responses and attitudes of Indonesian hadith scholars towards these theories through e-articles written in religious journals indexed in the Moraref portal of the Ministry of Religion. This research is library research. The method used in this research is content analysis. Data The main literature of this paper is e-articles in religious journals related to orientalism in contemporary hadith studies in Indonesia. The results of this research show the contribution of theories formulated by orientalists to the dynamics of contemporary hadith studies in Indonesia. The role of orientalists as skeptical outsiders creates a different perspective from Muslim hadith scholars, so that they build new theories in contemporary hadith studies. Orientalist theories that are discussed in contemporary hadith studies in Indonesia include; hadith fabrication theory, sunnah-hadith terminology, Common link, argumentum e-silentio, projecting back and isnad cum matan. The responses of hadith scholars to Orientalist theories is divided into several attitudes; descriptive-elaborative, descriptive-comparative, descriptive-appreciative and descriptive-critical.
Akseptabilitas Perawi Syiah dalam Sanad Riwayat Sunni: Analisis Riwayat Aban Ibn Taghlib dalam Kutūb al-Sittah
Authors: Mahdi Fahrizal
Published: December 2023

This research discusses the acceptability of the shia theology rawi in the Sunni tradition. Shia rawi narrated many ḥadīth in the main books of sunni ḥadīth and ḥadīth critics often give the a jarḥ so that their narrations are judged as da’if. Aban ibn Taglib is one of the Shia rawi who narrated the ḥadīth in al-Kutūb al-Sittah except in Ṣaḥīḥ al-Bukhārī. He has 5 ḥadīth in all those ḥadīth books and all of the are considered authentic ḥadīths except for only one ḥadīth in Sunan Abu Dawud. Therefore, the research concludes that Shia rawi can accept their riwayah as long as they meet the requirement for the validity of the ḥadīth and are not among the extreme shia who disbelieve and insult the companions of the prophet Muḥammad.
On knowing what you do (not) know
Authors: Pretorius Marilize
Published: December 2023

Overseas educated nurses’ (OENs) professional identity becomes threatened when limited communicative competence in the local language of their host country results in communication problems. While training is essential for increasing OENs’ communicative competence, their own perceptions of their competence should not be neglected. This article focuses on the impact of an English-language training programme on the self-perceived communicative competence of OENs (n = 68) in the United Kingdom. The effects of the training on their actual and self-perceived communicative competence, comprising competence in Task Focus (TF) and Rapport Building (RB), was examined using quantitative analysis based on pre- and post-training questionnaire and test data. It was found that there was a significant increase in the OENs’ self-perceived communicative competence from pre- to post-training. Further, Actual Task Focus (ATF) and Perceived Task Focus (PTF) competence correlated before and after training, whereas Actual Rapport Building (ARB) competence and Perceived Rapport Building (PRB) competence were not correlated before training, but did correlate after training. The pre-training lack of correlation seems to be due to an overestimation of competence. In sum, participants formed more accurate perceptions of their ARB competence through training. The results hold implications for developing OENs’ accommodative competence.
Telling the Transformation
Authors: Lyngdoh Margaret
Published: December 2023

I present a critical ethnographic documentation and analysis of the human-snake transformation tradition among the Indigenous Khasi Communities in Northeast India. I look at how traditional knowledge about the folklore of water is conceived through the first- person transformative experience of dreaming. This then catalyzes community responses to ‘were-snakes’ in multi-level contexts. This article is based on data from ethnographic fieldwork carried out with eight were-snakes over the course of seven years. Water is the generic resource, the ‘tradition-trope’, and it is used as an analytical category to look at all the oral narratives connected with the tradition, becoming a communicative modality through which clan, transformation, ecology, and further, the social organization of the Indigenous Christian community are processed.

Muslim-Based Schools in South Africa and the Potential for Interreligious Dialogue as Democratic Engagement
Authors: Davids Nuraan
Published: December 2023

The proliferation of Muslim-based schools which accompanied South Africa’s transition to a democracy provides significant commentary not only on the historical bearing of these schools but also on their perceived role in relation to a democracy. Notably, while there are definitive differences between the contextual ideologies of an apartheid and a democratic state, it is possible to trace a common thread behind the formation of Muslim-based schools: specifically, that the state cannot be trusted with the education of Muslim children. Arising from the trajectory of Muslim-based schools are two interests that this article seeks to explore. The first centres on the motivations behind Muslim-based schools and whether these have shifted since their historical inceptions. The second examines how Muslim-based schools might (re)conceive of themselves in a democracy by drawing on their own paradigmatic foundations as a guiding philosophy for interreligious dialogue as a form of democratic engagement.
Interreligious Solidarity in South Africa
Authors: Omar A Rashied
Published: December 2023

South Africa has a unique and vibrant interreligious solidarity movement. During the late 1980s and early 1990s, the interreligious movement played a significant role in the anti-apartheid struggle via the South African Chapter of the World Conference of Religions for Peace. Since the onset of a non-racial and democratic dispensation in 1994, the interreligious movement forms an integral part of South Africa’s burgeoning civil society, attempting to hold the post-apartheid government accountable for its political and moral mandate. This article explores the development of South Africa’s interreligious movement with special reference to the role of the Muslim community. It argues that, relative to its small size, the local Muslim community has played a disproportionate role in shaping the history and trajectory of the South African interreligious solidarity movement during the anti-apartheid struggle (1948–1994) and in the contemporary democratic period (1994–2023).
A Journey into Other Faiths
Authors: White Peter
Published: December 2023

We live in a world of diversity, and so it is with people’s religious beliefs and how they approach their religious practices in relation to a deity and their social and relational lives. Bible history has taught us that God has always allowed religious diversity. The biggest threat to the world is not poverty, health, and economic challenges but rather religious intolerance, the fear of compromising our faith, bias, and prejudice about other faiths. This article narrates the author’s experience and journey as a Pentecostal scholar in dialogue with other faiths. It argues that it is possible to study other religions without losing one’s own faith insofar as the various methods and principles for the study of religions can be applied. The article promotes the use of dialogue and spiritual discernment as tools to engage with people of other faiths. These approaches therefore become means of moving together toward life.

A helping hand
Authors: Goico Sara
Published: December 2023

In this article, I examine responses to the taking of food items during snack time in an early childhood education classroom with deaf toddlers (18 months to three years old) who are native signers of American Sign Language (ASL). These children have grown up with exposure to ASL from deaf family members and are attending a classroom where all individuals use ASL. Through the combined analysis of ethnographic and interactional data, I argue that the teachers’ corporeal socialization of the deaf toddlers into a visual orientation leads to their development of a social and moral understanding of ownership rights within the classroom which is displayed in the children’s social awareness, social responsiveness and self-reliance in responding to food takings.
Collaborative storytelling and hypothetical scenarios about romantic relationships among middle-school peers
Authors: Andréasson Fredrik
Published: December 2023

This study examines how preteen children negotiate and make sense of romantic relationships and index relational norms and boundaries in collaborative storytelling. The analysis draws upon an interactional approach to storytelling and examines how participants collaboratively describe, reshape and elaborate hypothetical scenarios. The interactional approach to storytelling is combined with a sequential analysis of membership categorization work to explore how the peers organize their participation in storytelling practices, while invoking categories to negotiate appropriate and inappropriate romantic relationships. The study demonstrates how children use hypothetical scenarios to turn the storytelling into a time machine for moving across time and space, while orienting to gender, social class and age as central to making sense of romantic relationships in their peer culture.

The incidence of renal cell cancer (RCC) is low in individuals aged less than 40 years; however several studies have shown this increasing trend over the years. Hereditary syndromes are associated with RCC and are more frequently observed in early-onset cases. In this study, we investigated the characteristics of the patients, aged less than 40 years, who were operated for a renal mass with the suspicion of RCC. We analyzed patients aged <40 years who underwent partial or radical nephrectomy between January 2012 and December 2022. A total of 618 patients underwent partial or radical nephrectomy and 60 (9.7%) patients were aged <40 years. A total of 62 renal masses were resected. The median age of the patients was 34 (31.75–38) years. RCC was detected in 50 (80.6%) lesions, while 12 (19.4%) lesions were benign. The most commonly observed benign tumors were oncocytoma and multicystic nephroma. Low-stage RCC (stage 1) was detected in 78% of patients. Recurrence was observed in two patients and both had von Hippel–Landau gene mutation. During follow-up, two patients were found to have lung metastasis, while another patient had bone metastasis. Three patients died during the follow-up period. Disease free survival rate was 89.58% and cancer specific survival rate was 93.88%. The incidences of kidney cancer in young adults are increasing; therefore, early discovery and the diagnosis are important. Further research is required to gain a better understanding.
Application of upconversion nanoparticles as a thermal sensor for biological tissue
Authors:   Saratov State University, Yanina Irina Yu , Kochubey Vjacheslav I. ,   Saratov State University
Published: December 2023

The paper shows the possibility of simultaneous registration of the temperature of nanoparticles embedded in the fat layer and temperature-induced phase transitions in the fat layer. The luminescence spectra of upconversion particles (UCNPs) were measured and analyzed in a wide temperature range: from room to physiological and further to a hyperthermic temperature resulting in tissue morphology change. Typical samples thickness of adipose tissue was 0.5 mm. The sample temperature varied between 25 °C and 60 °C. The temperature dependence of the UCNPs luminescence intensity from UCNPs deposited onto the sample surface (1 layer) and from UCNPs deposited between two layers of abdominal adipose tissue was recorded. In the course of adipocyte heating, lipids of fat droplet first transit from a crystalline form to a liquid crystal form and then to a liquid form, which is characterized by much less scattering. The high-temperature transition is recorded most well. The obtained results confirm a high sensitivity of the luminescent UCNPs to the temperature variations within tissues and show a strong potential for the controllable tissue thermolysis.
An automation of the detection processes of the strain characteristics of optical fibers, classification of their varieties and identification the influence factor according to Brillouin reflectograms
Authors:   Omsk State Technical University, Bogachkov Igor V.
Published: December 2023

Research results into the automating the processing of measurement data obtained from the Brillouin optical reflectometer, light guides containing various types of optical fibers are presented in this paper. By analyzing the parameters of the Mandelstam–Brillouin scatter obtained from Brillouin reflectograms, we can classify optical fibers in the studied telecommunication optical cables. This makes it possible to evaluate the change of the Brillouin frequency shift and determine the longitudinal fiber tension. The initial values of the Brillouin frequency shift and the profile of the Mandelstam–Brillouin scatter spectrum are different for each fiber type. The programs for automated processing of Brillouin reflectogram data are discussed. Estimation of the level of the back-reflected signal allows you to identify the factor, that had a predominant effect on the parameters of the Mandelstam–Brillouin scatter signal in the studied sections of optical fibers, and to compensate for the influence of temperature changes in the longitudinal strain distribution graphs. After that, we can plot a graph of the distribution of longitudinal strain along the fiber, caused precisely by mechanical influences on optical fibers. Conclusions about the accuracy of the estimates obtained by various algorithms, based on the accumulated experience in working with the presented programs are drawn.
