The extended setting time of mineral trioxide aggregate (MTA) is one of its primary drawbacks. An alternative to MTA, Nano Fast Cement (NFC) is a novel nanocomposite with a quick setting time. In order to develop an exceptional dental filler, hydroxyapatite nanoparticles (NHA) were introduced to NFC to examine its impact on setting time, biocompatibility, and bioactivity qualities. X-ray diffraction, scanning electron microscopy, Gilmore needle, and MTT assay were used to evaluate the specimens with 0, 10, and 20 W% hydroxyapatite. The antibacterial evaluation was conducted using Enterococcus faecalis (PTCC 1394). Using phase and microstructural studies, the production of hydroxyapatite was discovered. Both 10 and 20 weight percent prime apatite enhanced the specimens' bioactivity and markedly decreased their toxicity behavior. More HA content resulted in greater bioactivity enhancement and toxicity decrease. These results suggest that the physical properties of NFC were not negatively impacted by the addition of NHA. In vitro, they enhanced the filler's bioactivity.

Published: January 2025

Guided Bone Regeneration (GBR) has become an essential technique in dental implantology, particularly for cases with compromised bone volume that impact implant success. This narrative review examines the role of GBR in enhancing dental implant outcomes, focusing on its applications, biological principles, materials, and clinical protocols. GBR utilizes barrier membranes and bone graft materials to foster bone regeneration in deficient areas, creating a stable foundation for implant placement by preventing soft tissue invasion and promoting osteogenic activity. Through a literature review of recent studies, we assess the clinical efficacy of GBR in addressing bone insufficiencies resulting from periodontal disease, trauma, or resorption following tooth loss, with a particular emphasis on how GBR augments implant stability and long-term survival. The review explores various GBR materials, including resorbable and non-resorbable membranes, and graft types such as autografts, allografts, xenografts, and synthetic options. Additionally, advancements in bioactive membranes, growth factor-enhanced materials, and 3D-printed scaffolds are discussed for their potential to improve regenerative outcomes and reduce procedural complications. Best practices in clinical protocols, including preoperative planning, precise membrane placement, and post-operative care, are analyzed to highlight factors that enhance GBR success. Comparative analyses indicate that GBR significantly improves implant survival and reduces marginal bone loss, demonstrating its efficacy in complex cases. Despite its high success rate, GBR has limitations, such as the potential for complications like peri-implantitis and membrane exposure. The paper concludes with suggestions for future research on optimizing GBR materials, enhancing biological responses, and improving long-term outcomes to broaden its application in dental implantology. This review serves as a resource for clinicians and researchers seeking to maximize implant success through advanced GBR techniques.

Abstract
3D printing technology has introduced significant advancements in dentistry, particularly in the customization of dental prosthetics and orthodontic appliances. By enabling precise, patient-specific designs, 3D printing enhances both the fit and comfort of dental devices, improving patient outcomes and satisfaction. This technology offers notable efficiencies over traditional manufacturing methods, reducing production times and costs while supporting seamless digital workflows in clinical practice. Recent advancements in biocompatible materials and digital integration have expanded the application of 3D printing to a range of dental devices, from crowns and bridges to clear aligners and retainers. However, challenges remain, including material limitations, regulatory hurdles, and technical constraints that can impact adoption, particularly in smaller clinics. Future research aims to address these challenges by exploring new materials, incorporating artificial intelligence for optimized design, and enhancing environmental sustainability through waste reduction. The ongoing evolution of 3D printing in dentistry promises to further personalize and streamline dental care, paving the way for a more patient-centered, efficient, and accessible approach in modern dental practices.

Authors: Ghadirifard Mohammad , Eisaei Mitra , Hakimaneh Sayed Mohammadreza , Bafandeh Mohammad Amin , Shayegh Sayed Shojaodin
Published: January 2025

Background: The accuracy of intraoral scanners depends on the scanning strategy, but evidence on how these strategies affect trueness and precision across scanners is limited. Identifying optimal strategies is key to improving performance and clinical outcomes. Materials and Methods: A dental cast obtained from an impression of a fully-dentate patient was initially scanned by a laboratory scanner and then by three intraoral scanners namely Trios®4, Carestream 3800, and Medit i700 with three different scanning strategies of A (occlusal surfaces from the left end to the right end, followed by lingual and then buccal surfaces), B (buccal surfaces followed by occlusal and then lingual surfaces from left to right), and C (continuous labiolingual movement with left-to-right direction). Scans were converted to STL format and analyzed in Geomagic for trueness and precision (ISO 5725-1) using ANOVA, Tukey, Welch, and Games-Howell tests (alpha = 0.05). Results: The effect of scanning strategy was significant on trueness of Carestream (P=0.002) but not Medit and Trios4 (P>0.05). In Carestream, the trueness of strategy A was significantly higher than B (P=0.001). The effect of scanning strategy was significant on precision of Medit (P<0.001) but not Carestream and Trios4 (P>0.05). In Medit, the precision of strategy B was significantly lower than A and C (P<0.001 for both). Conclusion: The scanning strategy's effect on accuracy varied by scanner type. Strategy A was most accurate in Carestream, while strategy B showed the lowest precision in Medit i700. Other scanners and strategies had similar precision.

Authors: Shah Syed Waqar Hussain , Choudhary Arooba
Published: January 2025

The Handmaid’sTale is a dystopian fiction which has caught attention of many critics and metafiction readers for its stylistic and thematic approaches. The structuralist theory was morphing into post-structuralist theory at the time the novel came out. Thus, it is necessary to undergo the structuralist and linguistic relative analysis of this metafiction. This research paper attempts to understand the core essence of the predictions and connotations the novel has imbibed in itself. The research essay takes into account the studies that are already done on the novel and compare them to trace down the structuralist concerns that Margaret Atwood raises in her dystopian metafiction. This paper attempts to highlight the linguistic tools that uncover the underlying feminist resistance and rebellion that Atwood portrays in her female characters.
Exploring the Conceptualization of Time and History in Hamid’s Moth Smoke and The Reluctant Fundamentalist: An Intertextual Study
Authors: Janjua Muhammad Afzal Khan
Published: January 2025

Interrogating the chronological and teleological notions of time, this study explores the contemporaneity and relevance of the 'past' in Mohsin Hamid's two novels, Moth Smoke (2000) and The Reluctant Fundamentalist (2007), by engaging Julia Kristeva's postulations on 'Intertextuality'. Hamid's fictions interweaving the past and present are examined by utilizing Mudrovcic's views on history to affirm the viability of the 'relational' and cyclic nature of time which is opposed to the temporal succession and linearity. Accordingly, the conceptualization of history in Hamid's novels is scrutinized in relation to the 'authentic history', in a bid to establish the significance of History in shaping the present and predicting the future, thereby, renewing the prominence of time and history in spatial, temporal and theoretical spheres in post-modern times. Claiming to be a valuable addition to the scholarship on 'Time-Studies', this research would also help in rethinking and reinterpreting Pakistani anglophone fiction via unhackneyed standpoints.

Published: January 2025

This study explores biocomposites fabricated from coconut fiber (CF) and unsaturated polyester resin, enhanced using silane coupling agents. CF was treated in silane solution at various concentrations (0–10 wt%) to improve compatibility with the resin matrix. Biocomposites were prepared by press molding and characterized by using FTIR, SEM, TGA, and UTM to assess their morphological, mechanical, thermal, and physical properties. The results show that 10 wt% silane-treated fibers (PE-CF-TVS10) exhibited the best performance, achieving superior tensile (56.1 MPa) and flexural strength (155 MPa), enhanced thermal stability, and reduced water absorption and swelling. Morphological analysis confirmed improved fiber-matrix integration due to silane treatment, reducing porosity, and increasing material density. These findings highlight the potential of CF-based biocomposites as eco-friendly, highperformance alternatives for applications such as project helmets, offering reduced dependence on synthetic materials.

The clearing of peat swamp land which is exacerbated by poor water management causes damage to the peat ecosystem and is prone to land fires during the dry season. To overcome this problem, it is necessary to re-wet the land, including by building canal blockings. This study aims to examine community perceptions of land re-wetting activities in the framework of peat restoration in Merbau Village, Bunut Sub District, Pelalawan District. Data collection uses interviews, field observations, and document studies. Informants were selected purposively, namely community members involved and affected by peatland re-wetting activities. Data were analyzed by descriptive qualitative. The results of this study indicate that the community has different perceptions to the peatlands re-wetting using canal blocks built on the community's oil palm plantation land. Some people have a positive perception because they have felt the benefits from a socio-economic perspective and reduced the recurring peatland fires in Merbau Village. They even have the awareness to take care of the existing canal blocks. However, some people still object to the construction of canal blocks on their own land because it will disturb the oil palm plantations and the process of harvesting the palm fruit.Keywords: canal blocking, community perception, Merbau Village, peat.

The Karakuduk flint processing workshop in view of new technical and typological research
Authors: Madreymov Berik D.
Published: January 2025

The Karakuduk flint processing workshop is located in the eastern part of the Ustyurt plateau on the northern slopes of the Barsa-Kelmes depression (Republic of Karakalpakstan, a region of Uzbekistan), 1.5-2 km north of the well of the same name. The workshop was uncovered by E.B. Bizhanov in 1978. Surface finds were scattered over an area measuring 200 × 100 m. The collection includes more than 900 lithic finds. One part of them are flinty limestone plates, the other part includes flakes obtained from them. The size of the plates is mostly within 5–10 cm (sometimes bigger), the thickness is on average 1.5-2 cm. The length of most flakes is 2–3 cm (sometimes up to 5 cm). A series of bifacially processed tools was also revealed at the site. E.B. Bizhanov noted different degrees of preservation of artefact surfaces (the collection has not been studied in detail); all of the objects were attributed to the Acheulian. In this article, the author employs the technical and typological method as well as the “deflation rate” method (Derevianko et al., 2000, p. 204) to divide the artifacts from the site into three complexes. These are: Early Paleolithic including 86 items with strong surface deflation; Middle Paleolithic including 703 items with desert tan on the surface, in terms of cultural features they are included in the bifacial faction; and Late Paleolithic – 44 items which only have a patina.
The Lola Cultural circle and Caucasian migration: 2200 Cal BC
Authors: Mimokhod Roman A.
Published: January 2025

The article is focused on the reconstruction of the Caucasian population migration to the steppe around 2200 Cal BC. As a result of the movement of the Ginchin and Prisulak tradition bearers to the Ciscaucasia, where they came into contact with local late Catacomb cultures, the Lola cultural circle was formed, which included the Lola and Nevinnomyssk cultures, as well as the Volga-Ural cultural group. This migration is evidenced by a number of innovations of Caucasian origin in the ritual-inventory complex of the post-Catacomb cultural formations of Ciscaucasia and the Volga-Ural region. Their emergence was explosive in nature and occurred within a short period. The movement of individual pastoral societies from the North Caucasus to the steppe is well confirmed by the craniological data of the Lola culture, which, on the one hand, demonstrates a connection with the local Eastern Manych Catacomb culture, and on the other hand, shows a link with the cultures of the North-Eastern Caucasus. The migration in question occurred during a period of sharp climate aridization, which led to an increase in sedimentation and a decrease in winter temperatures in the mountain and foothill zones. This resulted in a shortage of winter pastures in these territories, which caused part of the Caucasian population to move to the steppe, where conditions for winter grazing were more favorable.
Analysis of the demographic structure of ancient communities in the context of bioarcheaological reconstruction
Authors: Buzhilova Aleksandra P. , Kuprikova Kseniya Yu.
Published: January 2025

Paleodemographic analysis is based on the principle of “biological uniformity,” which makes it possible to assume that, under natural living conditions, human populations are characterized by a certain age-sex structure, and possible deviations are limited by the biological characteristics of the species. Analysis and interpretation of the influence of various environmental factors on the demographic structure, average life expectancy and health level of ancient populations faces a number of methodological limitations. This paper provides an analytical review of methodological approaches and a modern interpretation of the possibilities of anthropological material as a source for a more or less objective reconstruction of the ancient population lifestyle. Specific examples of such approaches are shown in the analysis of Kozino’s anthropological series dating mainly from the 18th century (excavations by the Institute of Archaeology RAS).

Authors: Shchepetov V.V. , Fialko N.M. , Bys S.S.
Published: January 2025

In the work, the patterns of friction and wear of forsterite-based coatings were studied, and their structural-phase composition, conditions of formation and self-regulation of surface structures were determined from the standpoint of the structural-energy theory of friction. Detonation coatings developed on the basis of forsterite are characterized by high anti-friction properties. The conducted studies showed that the most appropriate application of the investigated coatings is to increase the reliability of operation of friction nodes during strengthening and restoration, for example, for moving pairs of control mechanisms, hinges of guide surfaces, cams, sliding supports, pairs with reciprocating movement, bearings, sliding guides, etc. in which the use of traditional lubricants is undesirable. Compounds of complex oxides of magnesium orthosilicate were used as the basis of composite coatings. The structural and phase composition of the coatings, the peculiarities of the formation of complex alloyed secondary structures, taking into account both the properties of the alloying elements and the structures formed by them, were established. The physical mechanism was determined and the main factors determining the level of thermodynamic graphitization were clarified. The studied self-lubricating compositions can be used both for strengthening and for high-quality restoration of worn triboelements by any technological methods using powder materials.

The article develops the theoretical principles of determining the trends in the development of the theory of management of external public debt. The existing studies on the theory of external public debt management are analyzed. In order to implement bibliometric analysis, a number of specialized methods and tools were used (built-in database tools Scopus та Web of Science, VosViewer, Google Trends, Publish or Perish). Considering the large number of scientific works devoted to external public debt, an in-depth cluster analysis was conducted in order to identify the main thematic groups presented in the literature. According to the results of spatial clustering, 6 groups of countries were identified, researchers from which have joint publications on issues of external public debt. On the basis of the bibliometric analysis, key results and general directions regarding the management of the external state debt were determined. The literature on external public debt management traditionally emphasizes debt feasibility, debt thresholds, and the role of fiscal policy in debt management. Recent research has focused on innovative debt management strategies, including contingent liabilities, debt restructuring, and the relationship between debt management and monetary policy. Scholars identify various macroeconomic variables, such as GDP growth, inflation rates, budget deficits, and exchange rates, as the most important determinants of public external debt. The quality of institutions, management structures, and political stability significantly affect the dynamics of external public debt and its management strategy. Researchers have developed concepts and models for assessing the sustainability of external public debt, taking into account such factors as the ratio of debt to GDP, the ratio of debt service to income and external shocks. The literature discusses various debt restructuring mechanisms, such as debt forgiveness, debt extension, and debt buybacks, and their impact on debt sustainability and economic recovery. Research examines the role of international financial institutions, coordination among creditors, and policy interventions in managing external debt crises and promoting sustainable debt restructuring. The literature examines the role of international financial institutions, such as the International Monetary Fund and the World Bank, in providing technical assistance, policy advice and financial support for effective external debt management. Researchers analyze the functioning of sovereign debt markets, including bond issuance, debt securities pricing, secondary market trading, and the impact of market conditions on debt management decisions.

The methodical principles of assessment have been improved and the institutional role of the external public debt management bodies of Ukraine has been identified in conditions of geopolitical instability. It remains important to achieve a reduction in the size of the debt burden; reformatting the structure of the state debt in favor of its internal component, as well as establishing uniform debt repayment schedules with a possible extension of their terms and an increase in the average term of their fulfillment; continuation and deepening of cooperation with international financial organizations and governments of foreign countries regarding preferential financing of the country's reconstruction and modernization in the post–war period of development, primarily on the basis of the implementation of innovative and investment development of the national economy. The results of the analysis of the retrospective and current state of application of the mechanism for managing state borrowing and guarantees of Ukraine, first of all, point to the undisputed conclusion about the ambiguity of the role of external state debt in stimulating economic growth, stabilizing state finances, and achieving price and financial stability. The assessment of the effectiveness of the relevant institutional authorities in the management of Ukraine's external public debt was carried out using generally recognized indicators of debt security in world practice. The values of absolute and relative indicators of determining the state of management of state external debt obligations, during the selected time period of the study, were almost constantly influenced by both external and internal transformational or geopolitical factors (changes in the political system in the country, annexation of parts of the eastern and southern territories, a change in the geopolitical course of Ukraine's development, the COVID–19 pandemic and the most significant problem – the war).

Penggunaan kunci pintu konvensional di ASPIKA sebagai alat bantu untuk mengakses ruangan dinilai memiliki tingkat keamanan yang rendah karena anak kunci dapat diduplikat oleh siapapun sehingga orang yang tidak memiliki hak akses atas pintu tersebut juga dapat mengakses pintu. Selain itu penggunaan pintu konvensional juga tidak dapat memantau waktu akses pintu sehingga penghuni dapat mengakses pintu kapanpun melewati batas waktu yang telah ditetapkan oleh pengurus ASPIKA yaitu jam 9 malam. Berdasarkan permasalahan yang ada maka dibuatlah sebuah alat sistem otomatisasi dengan memanfaatkan RFID sebagai pengganti anak kunci dan electromagnetic doorlock sebagai pengunci pintu otomatis. Pada penelitian ini juga dibangun sebuah website untuk memonitoring aktivitas akses pintu di ASPIKA. Adapun tahapan penelitian yang digunakan dalam peelitian ini adalah pendekatan, pengembangan, implementasi dan pengujian. Hasil pengujian meliputi pengujian fungsi RFID, pengujian fungsi electromagnetic doorlock, pengujian fungsi LCD i2c, pengujian fungsi push button dan pengujian website. Kesimpulan dari penelitian ini ialah pintu dapat terbuka secara otomatis dengan mendekatkan RFID tag ke RFID reader. Hasil pemantauan waktu akses pintu dapat diakses pada website yang telah dibangun.

Penelitian studi kasus ini melibatkan 32 siswa dengan tipe kepribadian sensing dan intuiting. Instrumen penelitian mencakup tes kepribadian MBTI (Myers-Briggs Type Indicator), lembar tes soal HOTS, dan wawancara. Data dikumpulkan melalui triangulasi sumber dan waktu, dianalisis menggunakan reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan kemampuan koneksi matematis siswa dengan tipe kepribadian sensing lebih baik (70%) daripada tipe intuiting (56,25%). Temuan ini mengindikasikan siswa dengan tipe sensing lebih efektif dalam mengaitkan dan menerapkan konsep matematika pada soal HOTS berbasis budaya Jambi, sementara siswa dengan tipe intuiting menghadapi kesulitan dalam membangun koneksi matematis, yang mempengaruhi akurasi jawaban mereka. Dengan demikian, tipe kepribadian memiliki pengaruh signifikan terhadap kemampuan siswa dalam mengintegrasikan dan menerapkan pengetahuan matematika dalam situasi kompleks.
Connection abilities are important as part of higher order thinking skills. This study aims to explore students' mathematical connection skills in solving HOTS problems based on Jambi culture, with a focus on the Kajang leko traditional house and the padamaran cake typical of Jambi. This research used a case study approach involving 32 students with sensing and intuiting personality types. The research instruments included MBTI (Myers-Briggs Type Indicator) personality tests, HOTS question test sheets, and interviews. Data were collected through triangulation of sources and time, then analyzed using data reduction, data presentation, and conclusion drawing. The results showed that students with sensing personality type had better mathematical connection ability (70%) than students with intuiting type (56.25%). This finding indicates that students with the sensing type are more effective in connecting and applying mathematical concepts to Jambi culture-based HOTS questions, while students with the intuiting type face difficulties in building mathematical connections, which affects the accuracy of their answers. Thus, personality type has a significant influence on students' ability to integrate and apply mathematical knowledge in complex situations.

Бүгінгі қоғамда орын алып отырған жаһандану мен гуманизация эстетикалық-рухани саладағы құндылықтарды бағалаудың жаңа парадигмасын орнықтырды. Осы ретте ұлттық мәдениет пен әдебиетке, оның салаларына  ерекше көңіл бөлу қажеттігі туындайды. Сын – қоғамдық даму мен санаға, көркемдік қабылдауға әсер ететін ерекше форма. 
Әдеби сын – әдебиеттанудың құрамдас бөлігі ретінде, әдебиеттің тарихы және теориясымен тығыз байланысты болады. Сын сөз өнерін тануға, өмір шындығын эстетикалық тұрғыда игеру заңдылығын түсінуге бағыттайды. Сол арқылы әдеби шығармашылықтың мән-маңызы ашылады. Әдеби сын әдеби үдерістің дамуын бағалап, көркем туындыны бүгінгі күн тұрғысынан саралайды. Әдеби-көркем дүниенің идеялық-эстетикалық сапасын бағдарлай отырып, сын оның нақты кезеңдегі даму деңгейін айқындайды. Осы тұрғыдан келгенде сынның да даму, кемелдену сатысы болған. Әдеби сынның тарихи тамырын аңдағанда, оның тереңде екеніне көз жеткіземіз. Сынның объективтілігі мен көркем-эстетикалық бағалауы әдебиет пен өнердің төмендеуін болдырмауға ықпал етеді. Сын жанры өткір, сарабдал сыншыны қажет етеді. Сынның дамуында танылған тұлғалардың бірі – Т.Кәкішұлы. Зерттеушінің сын саласындағы еңбектері осы жанрға қосқан ерекше үлесін байқатады.

Published: January 2025

With the adoption of a law obliging film producers to supply films receiving state support with audio description, the issue of training specialists in this field arose. However, the existing terminological barrier between the Russian and international practice of audio description (typho commentary) in many ways complicates the exchange of experience between specialists. The article briefly discusses the stages of the development of audio description and the terms that were used to denote the process of verbal description of audiovisual works. The analysis of audio description as a type of intersemiotic translation is given. The evolution of the Russian term “typho commentary” and its convergence with international analogues is shown.
