A QbD Based RP-HPLC Method for Stability Indicating Impurity Profiling of Pyridoxine: Method Development, Validation, and Application
Authors: Chavan Avinash , Gandhimathi R
Published: October 2023

Pyridoxine impurity profiling in bulk and formulations was devised and validated using a reversed-phase high-performance liquid chromatography (RP-HPLC) strategy. The technique was fine-tuned using an Analytical quality by design (QbD) approach, ensuring its dependability and sturdiness. Linearity, accuracy, and precision were carefully examined as key performance indicators. With a relative standard deviation (RSD) < 2%, the approach showed exceptional precision, excellent recovery rates (100 and, 101.2%), and a strong correlation value (R2 = 0.9990). The technique has been used successfully for impurity profiling, and because it indicates stability, it can be used for long-term stability studies. The work contributes to the body of knowledge and has applications for pharmaceutical quality assurance.

Authors: Suryawanshi Chandrakant , Wagh Rajendra
Published: October 2023

The monoamine oxidase (MAO) enzyme resides in the outer mitochondrial membranes of all body cells, including the ones found in the brain, liver, and intestinal mucosa. Dopamine, serotonin, norepinephrine, tyramine, and tryptamine are extrinsic and indigenous amines that MAO oxidatively deaminates. MAO-A has been correlated with depression and other mental health issues, while MAO-B has been associated with the conditions Alzheimer’s and Parkinson’s disease. In a targeted assessment of naturally occurring anthraquinones, two isoforms of recombinant human MAOs were utilized. The inhibitory effects of purpurin and alizarin on MAO-A were observed, with calculated IC50 values of 2.50 and 30.1 M, respectively. This research on anthraquinones, purpurin, and alizarin offers promising new information that might eventually be used as a lead molecule in the discovery of the unique synthetic anthraquinones, anthracene 9, 10-dione compounds 1 to 9. On 96-well black polystyrene microtiter plates, both MAOs inhibiting action of 9 distinct synthetic anthracene 9,10-dione compounds has been evaluated. Compared to clorgyline, compounds 1, 2, 5, 8, and 9 inhibit MAO-A significantly, while compounds 1, 3, 5, 8, and 9 considerably inhibit MAO-B. Significant findings indicate that these compounds may be beneficial When employed to treat depression owing to their intense selective MAO-B activity and antidepressant effects as a result of their selective MAO-inhibition.

Authors: Trivedi Dharmesh , Joshi Seema , Jain Amit , Jadkar Sagar S , Jadhav Rahul I , Rathore Gajendra S , Sharma Anshu
Published: October 2023

It is feasible to extract nanocellulose, in particular alpha nanocellulose, from agricultural waste products such as cow dung. This is the case. Nanocellulose of this particular form exhibits unique properties, making it an excellent candidate for biological applications. This review aims to discuss the biomedical applications of cow dung-derived alpha nanocellulose. Nanocellulose has a larger surface area, greater mechanical strength, and better biocompatibility than other cellulose nanomaterials. It starts off by walking through the process of removing nanocellulose from cow manure. Alpha nanocellulose has applications in tissue engineering, the administration of medicines, the healing of wounds, as well as biosensing. Each application is broken down into its component parts, providing insights into the underlying mechanisms, experimental investigations, as well as in-vitro and in-vivo evaluations to establish the viability and effectiveness of alpha nanocellulose. The review paper also discusses the difficulties encountered and the potential future applications of alpha nanocellulose derived from cow dung in biomedicine. These difficulties include the requirement for standardized extraction processes, the optimization of material properties, and the consideration of regulatory issues. This in-depth study demonstrates that alpha nanocellulose that is generated from cow dung is a versatile and environmentally friendly nanomaterial that can be used for medical applications. It is hoped that the findings of this study will inspire more research and creative applications based on the unique properties of alpha nanocellulose, possibly resulting in biomedical breakthroughs by consolidating knowledge and exploring new areas.

Authors: Moncur Eleanor M. , Murphy Mary , Craven Claudia L.
Published: October 2023

Foramen magnum decompression (FMD) is a standard neurosurgical procedure, typically utilized to treat Chiari malformation. The aim of this educational project was to develop and validate a low-cost FMD simulation training model. Mold-based methods were used to develop a prototype. Feasibility was tested during an FMD training session for 17 neurosurgery trainees. Face and content validity were assessed through a Likert Scale. The perceived training benefit was determined using the Physician Performance Diagnostic Inventory Scale (PPDIS). A total of 87.5% successfully removed the C1 arch, 81.3% successfully performed an FMD, and 68.8% avoided injury to the underlying structures. The model scored highly for visual and tactile realism. The median confidence rating on PPDIS significantly improved from early learner to competent. We demonstrate feasibility, content, and face validity. Furthermore, this is a low-cost, portable model that can be easily replicated and used for simulation training.
The origin of subdwarf B stars
Authors: Aubrey Callum , Napiwotzki Ralf
Published: October 2023

The origin of subdwarf B stars (sdBs) is unclear. Different formation channels are proposed including: close-binary evolution, helium-mixing on the red giant branch and the hot flasher scenario. Circumstantial evidence exists that sdBs can result from single star evolution in high metallicity populations. We investigate this possibility by using membership in the thin, thick disk and halo populations as a metallicity indicator. Radial velocity measurements were com-bined with Gaia proper motions to calculate space motions in the Galaxy. Galactic orbits and population memberships were derived. Preliminary results indicate more sdBs are members of the thin disk (86 sdBs) than of thick disk and halo (28 sdBs). Apparently single sdBs are found among all three populations. We look into the temperature distributions of the different types and discuss implication for formation scenarios.
The fastest hot subdwarfs revisited
Authors: Heber Ulrich , collaboration MUCHFUSS
Published: October 2023

Hyper-velocity stars (HVS) are enigmatic objects because they are travelling so fast that they escape from the Galaxy. Among hot subdwarfs, only one such star is known, the He-sdO US 708. The Hyper-MUCHFUSS collaboration provided additional HVS candidates. Here we revisit the fastest candidates including US 708 by analysing optical spectra and spectral energy distributions using a new grid of tailored model atmospheres and report preliminary results. The sample is dominated by H-rich subdwarfs and their distribution in the Kiel diagram appears to be bimodal for the sdB stars but otherwise fits canonical evolutionary models well. Gaia’s proper motion measurements allowed a precise kinematic investigation to be made. It turns out that all previously proposed HVS candidates are actually bound to the Galaxy, except US 708. The original candidate sample turns out to belong to an extreme halo population. The scarcity of available observations of US 708 calls for space-based UV and IR photometry as well as high precision radial velocity measurements.

Published: October 2023

We present a search for new variable hot subdwarfs from Gaia eDR3 using the Zwicky Transient Facility DR9 and the 2.1 m Otto Struve Telescope at McDonald Observatory. We report the discovery of 22 HW Vir binaries, 24 reflection effect binaries, and 14 ellipsoidally modulated systems. Candidate selection for our high-speed observations was based on object location on the Gaia color-magnitude diagram and on intrinsic variability, which we estimate from the Gaia G flux uncertainties. Notable discoveries include a candidate 72 min period sdB+WD binary and two short period HW Vir binaries with periods around 67 min and 79 min, which includes the shortest-period eclipsing sdB+dM/BD discovered to date.

Authors: Snowdon E. J. , Jeffery C. S. , Schlagenhauf S.
Published: October 2023

The Southern African Large Telescope (SALT) survey of He-rich hot subdwarfs has identi-fied several binary candidates from variable or anomalous radial velocities, or unusually high rotational velocities. Many SALT survey objects have also been observed by the Transiting Exoplanet Survey Satellite (TESS). TESS light curves provide orbital periods and can also give clues about the nature of binary systems by distinguishing ellipsoidal variations from reflection effects. We present a summary of the candidate binary fraction within the SALT survey, as well as a breakdown of the identified candidates by spectral and helium class.

Published: October 2023

Hot subdwarf stars are small post-red-giant-branch stars. To this day, no planets have been confirmed around them. In this document we present the first results of our analysis to quantify the presence of planets around hot subdwarfs by performing a wide transit survey using photo-metric data from the first part of the mission TESS. Our work shows an absence of transiting planets for the majority of these stars, but some display potentially interesting signals. These are now observed in our follow-up procedure. We also compute upper limits of the occurrence rates for planets around hot subdwarf stars from the numerous stars displaying no signal.

Published: October 2023

TIC 033834484 and TIC 309658435 are long-period pulsating subdwarf B stars, which were observed extensively (675 and 621 days, respectively) by the Transiting Exoplanet Survey Satellite (TESS). The high-precision photometric light curve reveals the presence of more than 40 pulsation modes including both stars. All the oscillation frequencies that we found are associated with gravity (g)-mode pulsations, with frequencies spanning from ∼80 µHz (2 500 s) to ∼400 µHz (12 000 s). We utilize the asteroseismic tools including asymptotic period spacings and rotational frequency multiplets in order to identify the pulsational modes. We found dipole (l = 1) mode sequences for both targets and calculate the mean period spacing of dipole modes (ΔPl=1), which allows us to identify the modes. Frequency multiplets provide a rotation period of ∼64 d for TIC 033834484. From follow-up ground-based spectroscopy, we find that TIC 033834484 has an effective temperature of 24 210 K (140), a surface gravity of log g/cms-2 = 5.28 (03) and TIC 309658435 has an effective temperature of 25 910 K (150), a surface gravity of log g/cms-2 = 5.48 (03).

Published: October 2023

An organocatalytic annulative sulfur(VI)-fluoride exchange (SuFEx) reaction of β-arylethenesulfonyl fluorides has been reported. Under the catalysis of 10 mmol% BTMG and molecular sieves 4Å, β-arylethenesulfonyl fluorides undergo Michael addition-intramolecular SuFEx click reaction with benzofuran-3(2H)-ones to give δ-sultone-fused benzofurans in 76-99% yield. Using 10 mmol% DBU and molecular sieves 4Å, β-arylethenesulfonyl fluorides coupled with oxindoles to produce δ-sultone-fused indoles in 81-85% yield. In these reactions, molecular sieves 4Å act as efficient HF scavenger, which avoid the using of stoichiometric silicon additives and bases. Importantly, density functional theory (DFT) calculations reveal that Michael addition is a decisive speed step for the reaction.
Olympos 3 No’lu Kilise’den Yeni Bulgular Işığında Az Bilinen Bir Uygulama: Ahşap Kat Zemini Üzerine Mozaik Döşeme
Authors: EVCİM Seçkin
Published: October 2023

Antik çağın çeşitli tipteki mozaik uygulamaları günümüzde karşımıza çoğunlukla sağlam bir altyapı üzerine zemine serilmiş olarak veya yatak harcı ile duvar ve örtü sistemi yüzeylerine uygulanmış olarak çıkmaktadır. Bununla birlikte Vitruvius’un De Architectura adlı eserindeki zemin yapım talimatları ve bazı az sayıdaki arkeolojik kalıntı sayesinde ahşap üst kat zeminlerinin de konsantre alt katmanlı taş plakalarla veya tesseralarla kaplanabildiği anlaşılmaktadır. Bu yöntem ve uygulama şekli bu tip döşemelerin muhtemelen yaygın olmayışından dolayı arkeolojik verilerin yetersiz kalmasıyla pek fazla tanınmamaktadır.

Olympos Antik Kenti kazılarında, 3 No’lu Kilise’nin yan neflerinde bu tip bir döşemenin nefler üzerindeki galerilerin zemininde opus tessellatum tekniğinde uygulanmış olabileceğine dair bulgular elde edilmiştir. Eldeki verilere göre kilisenin galerileri, duvarlar ve nef ayrımı tarafından taşınan ahşap kiriş ve kaplama ile oluşturulmuştur. Duvarlardaki kiriş yuvaları ve taşıyıcı sisteme ait yıkıntı bunu açık bir şekilde göstermektedir. Her iki yan nef zemini üzerinde ve nef ayrımına ait yıkıntının hemen altında nef zeminine ait olmayan, parçalanmış durumda mozaik parçalarına, tesseralara ve bunların alt tabakalarına dair kalıntılara rastlanmış olup, bu kalıntıların ahşap konstrüksiyonlu galerilerin zemin döşemesine ait olduğu düşünülmektedir.

Bu çalışmada Olympos 3 No’lu Kilise’deki bulgular üzerinden ahşap üst kat zeminlerine mozaik döşemelerin nasıl inşa edildiği diğer bazı örneklere de değinilerek açıklanmaktadır.
Some Aspects of Religiosity in Ostia Antica Through Mosaics
Authors: LICORDARI Antonio , LICORDARI Francesca , PELLEGRINO Angelo
Published: October 2023

While mythology is one of the most widespread themes in the mosaics of Ostia Antica (both floor and non-floor), some compositions have a marked importance from a religious and cultic point of view.
We intend to examine the mosaic representations of aspects of the Ostian cults, among which that of Mithras stands out in a particular way for its diffusion and for the amplitude of its testimonies. The mosaic undoubtedly had the purpose of immediate visual communication of its contents, also because the religion of Mithras was accepted above all by low-level believers for whom communication through images was more suitable. However, in Ostia, among the followers of the cult, there is evidence of high-ranking personages, perhaps even belonging to the imperial family.
Next to that of Mithras we want to highlight the cult of Sabazio, of other oriental divinities in the past traces have been found, sometimes rightly and sometimes wrongly, in the House of the Dioscures, in the House of the Fishes, in the Neptune’s baths and in the opus sectile building of the Marine Gate (4th century AD).

Published: October 2023

The “Parco della Pace” was born in Ravenna in 1988, under the initiative of the Municipality of Ravenna and with the support of International Association of Contemporary Mosaicists (AIMC) and UNESCO. Considered a real open-air museum, it preserves nine monumental works of contemporary mosaic made by internationally renowned artists. A plan for the redevelopment and enhancement of the entire park has recently been approved: the agreement between the Municipality of Ravenna, the University of Bologna, the Flaminia Foundation, and the RavennAntica Foundation made possible the restoration of the fountain mosaic “Le chaos et la source de vie” by Claude Rahir, realized in 1984. The first part of the intervention focused on a careful study of the archival documentation that provides an understanding of the artist’s spirit and volition. The restoration techniques, put in place to re-establish the artwork compromised by years of neglect and vandalization, have allowed us to compare products and methodologies now standardized with others of recent experimentation. Special attention had to be given to the problem of the integration of gaps, relating the theory of restoration applied to protected cultural heritage with the world of contemporary art. In support of the intervention a three-dimensional survey of the artwork has been created using the “Structure from motion” technique. The project ended with the enhancement and redevelopment of the entire area through the setup of a dedicated website and explanatory panels.
Mozaikte Tamamlama: Uygulama Biçimleri ve Koruma Bakış Açısıyla Değerlendirmeler
Authors: ŞENER Yaşar Selçuk
Published: October 2023

Arkeolojik kazılarda ele geçen mozaikler gerek hazırlık katları gerekse tesellatum tabakasında dağılma ve eksiklikleri ile çoğunlukla bozulmaya uğramış halde bulunur.

Kazı çalışmalarıyla ele geçen, tessellatumda eksikleri veya eksik taşıyıcı katları bulunan mozaiklerde tamamlama, diğer etkin koruma uygulamalarıyla birlikte yapılmaktadır. Tamamlamaya yönelik uygulamalar genelde mozaiğin boyut ve büyüklüğünün algılanmasını kolaylaştırmak ve mevcut parçalarının daha sağlam hale getirilmesini sağlamak veya bazen de sadece estetik bütünlük kazandırmak amacıyla yapılmaktadır.

Yönümüzü uygulamalara çevirdiğimizde, genelde korumada kabul edilen uluslararası ilkelere bağlı kalındığı görülür, ancak bazı uygulamalarda koruma amacının dışına taşan, tasarım düzeyine ulaşan, “aşırı” sayılabilecek müdahalelerin de yapıldığı görülmektedir.

Bu çalışmayla mozaiklerde gerçekleştirilmiş tamamlama uygulamaları ele alınmış; koruma alanında üzerinde çok da kapsamlı çalışılmamış olan tamamlama konusuna dikkat çekilmek istenmiş ve uygulamaların irdelenmesine katkı sağlamak amaçlanmıştır. Nitekim antik dönemden günümüze kadar uzanan mozaikteki tamamlama uygulamaları seçilmiş örneklerle irdelenirken, özellikle çağdaş restorasyon uygulamalarına ağırlık verilerek yaklaşım/uygulama türlerinin tanıtılması ve uygulamaların koruma bakış açısından değerlendirilmeleri hedeflenmiştir

Authors: KÜRTÖSİ Brigitta Maria
Published: October 2023

The paper aims to demonstrate the creative process of the realization of a fountain in the courtyard of the Archbishop’s Castle in Kalocsa, Hungary. Lead architect of the diocese, Márta Vörös designed a complex artwork symbolizing the Trinity. The rounded shape concrete body of the fountain is seven metres in diameter and positioned in the middle of the inner garden space. In the centre of the composition, an orb and a dove figure are encompassed by a thin layer of water in a calyx-form. The surface of the fountain will be covered with Murano glass mosaic executed by the author. The dark colours from deep tones through the transition of blueish and greenish tints turn to golden shades reflecting to the Earth and Sky. The mosaic is made by direct technique in studio following a division system composed by 36 slices with 11 sections of each. The prepared sections are edited to fit to the curved design of the fountain, and the setting style desires to delicately amplify the symbolic content. From above the work will look like the eye of God as a universal protective symbol. This contemporary artwork exemplifies the fusion of traditional visual and theoretical values.

Recycled Polypropylene Fibres for Reinforcing Cement Mortar under Arid Conditions
Authors: Bendjillali Khadra , Chemrouk Mohamed
Published: October 2023

Concreting in arid environment is a delicate operation, due to many problems, such as the premature evaporation of mixing water, which affects the material consistency and the shrinkage cracking which threatens its durability. The present experimental work is conducted to investigate the physical and the mechanical behaviour of cement mortar reinforced by recycled polypropylene fibres under arid conditions, at 45 °C and 30% RH. The used polypropylene fibres are recycled from a domestic plastic waste. The tests realized in this investigation include the workability, the total shrinkage, the flexure and the compression tests. Through this investigation, the beneficial effect of recycled polypropylene fibres as reinforcement of cement mortar is well demonstrated, particularly under arid environmental conditions. The obtained results showed a substantial increase in the flow time of about 53% in mortar reinforced by 1% of recycled polypropylene fibres (1RPFM). It is also shown that under arid conditions, the presence of 1% of recycled polypropylene fibres in cement mortar leads to a considerable decrease in total shrinkage of about 46% and an increase in the flexural and compressive strength of about 24% and 26%, respectively, compared to control mortar (CM) at the age of 194 days. Overall, the used recycled polypropylene fibres have presented a high capacity to improve the different properties of cement mortar and make it a suitable composite for concreting in arid environment.

The urban form of Doha city has undergone numerous changes owing to rapid economic growth during the past few decades. The Qatar National Vision 2030 highlights Environmental Sustainability as one of the key sectors of Qatar’s First National Development Strategy. Achieving Environmental Sustainability requires analysis from meso and micro scales. This study selected a high-rise neighbourhood (West Bay) and a low-rise neighbourhood (Onaiza) in Doha city to be analysed. The study objectives are to, a) investigate environmental factors based on two levels: meso and micro scales and, b) develop planning strategies to enhance Environmental Sustainability in both low-rise and high-rise neighbourhoods. The research tools include content analysis, observation study and open-ended interviews. The results revealed similarities in lifestyle preferences for meso parameters, walkability and waste segregation, and micro parameters, surroundings and green infrastructures. Backyard farming is preferred by the low-rise neighbourhood while high-rise neighbourhood residents choose more sustainable alternatives for mobility. The study emphasizes the importance of public awareness and participation in formulating urban policies due to the changing dynamics of the city’s population.
The nexus between emotional intelligence, learning engagement, motivation, and achievement in team-based mobile language learning
Authors: Imamyartha David , Widiati Utami , Anugerahwati Mirjam
Published: October 2023

The extant literature on the integration of mobile instant messaging (MIM) into language pedagogy has documented its potential to leverage engagement and learning outcomes. Nevertheless, how individual differences in regard to emotional, sociocognitive, and motivational bearings contribute to language learning gains is hardly documented. This study is devoted to addressing this lacuna through an analysis of structural equation modeling (SEM) which explores the association between trait-emotional intelligence (TEI), online learning engagement (OLE), EFL learning motivation, and their grades in English for Academic Purposes (EAP) programs. Three-hundred-seventy-one freshmen in an Indonesian university were involved in EAP programs framed in team-based mobile language learning (TBML), mediated by Telegram as a complementary learning app. The students responded to an online survey eliciting their post-lesson perception of the abovementioned variables. Students’ course grades complemented the data collection. The results of our SEM analysis acknowledged the linear correlation from TEI, OLE, to EFL motivation as the drives to students’ learning achievement. This has also been supported by a robust correlation between the variables. The findings of the present study implicate the pedagogical potentials of TBML to scaffold self-regulated learning and satisfactory language learning gains, provided that students’ emotional intelligence, engagement, and motivation are intensively potentiated across different learning phases. Research limitations and recommendations are also explored.

Authors: Bawaneh Ali Khaled , Al-Salman Subreen Mahmoud , Rababh Belal Sadiq
Published: October 2023

The most important benefits appear in ability of distance education (DE) to face challenges related to classroom education, as student’s absence from lesson does not affect it. DE also reduces waste of time and money to reach school or university and enhances aspects of self-responsibility. When student is self-disciplined, she is given a greater opportunity to expand sources of knowledge. This study aimed to explore to which extent Jordanian science and mathematics teachers satisfied towards DE and identify their attitudes and challenges they faced considering some variables: teachers’ gender, region, school stages they teach, experience, knowledge in technology skills, and specialization. Study population consisted of all Jordanian teachers in public schools from all regions in Jordan. The study sample included 499 male and female teachers. We developed a study questionnaire, which contained 27 items. After examining its validity and reliability, it was spread out electronically according to snowball method. The study showed several results, science and mathematics teachers’ satisfaction of DE was moderate, and there were no statistically significant differences in value of importance of DE for all variables except teachers’ competence of information and communications technology (ICT) knowledge and skills. The results indicated that level of Jordanian teachers’ attitudes to DE was moderate, and there is a difference in their attitudes towards DE in favor of teachers who master ICT knowledge and skills. The results showed a difference in teachers’ attitudes according to their specializations for benefit of scientific track while there were no statistically significant differences for rest of the study variables. Finally, the results pointed out that there are many challenges facing teachers in DE, which came in strong category. The study results presented no statistically significant differences regarding challenges teachers faced in DE in all study variables. The study suggests training teachers on employing DE strategies effectively and implementation of digital applications and educational media. Also, it suggests redesigning academic content according to DE models and theories, designing assessment strategies and tools to measure achieving of the learning outcomes, providing schools with infrastructure of DE, and providing free and sufficient internet services and computers or laptops for teachers.
Development of learning path map of work and energy for high schoolers by using cognitive diagnostic assessment
Authors: Wancham Kittitas , Tangdhanakanond Kamonwan
Published: October 2023

The conception of work and energy is fundamental to learning physics and is essential to learning other subjects. However, most students still lack knowledge and understanding of work and energy. This may be due to previous research that aimed to develop students using similar teaching methods without considering the individual knowledge state of each student. We, thus, sought to develop the mastery test on work and energy and the learning path map of work and energy using cognitive diagnostic assessment. Participants were 537 tenth graders in Bangkok, Thailand, which were chosen by the multistage random sampling. The mastery test on work and energy developed is divided into six attributes, i.e., (1) work, (2) power, (3) kinetic energy, (4) gravitational potential energy, (5) elastic potential energy, and (6) law of conservation of energy. The test exhibited good psychometric properties, which were evaluated based on item parameters, content validity, construct validity, concurrent validity, classification consistency index, and classification accuracy index. The significant finding was the development of the learning path map of work and energy. The map illustrates students’ learning progression in different attribute profiles regarding work and energy. It proves to be highly beneficial for teachers in designing personalized learning methods for individual students. Additionally, it allows for tracking the learning progress of students until they have a comprehensive understanding of work and energy in all its attributes.

The findings in this study are that there is a novelty method that can be used in the preparation of academic manuscripts, namely the Rule Identification Urgency Solution (RIUS). With the RIUS method, an academic text can be used as a basis or basis for argumentation in the formation of laws and regulations or regional regulations. In conclusion, the RIUS method is a method that can analyze the rule of law, identify problems, the urgency of why these regulations are needed, and the solutions that can be provided. The RIUS method was first applied by researchers in preparing academic texts for regional regulations in the Badung Regency Government and Jembrana Regency Government, in this case researchers as experts in preparing academic manuscripts. Suggestions that can be given are that in the preparation of academic papers it is best to focus on analyzing what problems occur in society so that a regulation is needed.
Experience in the development of magnetic gravity separation at enterprises in Russia and CIS countries to improve the quality of iron ore raw materials
Authors: Opalev A.S. , Cherezov A.A.
Published: October 2023

The paper analyzes the tasks of producing high-quality iron ore concentrates suitable for nonblast-furnace metallurgy and the challenges of processing magnetite ores with the current technological level of dressing equipment and technologies. One of the best methods to improve the quality and the grade of iron ore raw materials is the use of magnetic gravity separation in the technological process, which allows selective separation of the liberated magnetite particles from their aggregates in processing of undersize products of fine vibrating screening. This trend is implemented in the innovative magnetite ore processing technology that uses the principle of the staged output of finished concentrate. The technology makes it possible to produce a high-quality concentrate after the first grinding stage. The magnetic gravity separation has undergone industrial validation, has proven its efficiency in practice, and has become widespread at mining and processing plants not only in Russia, but also in the CIS countries. Over 180 MGS-2.0 magnetic gravity separators produced by Russian manufacturers have already been or are being implemented at various Russian and CIS companies. Industrial separators are equipped with modern automation systems providing high technological separation performance, have no rotating parts and are simple in design. The authors continue R&D works on creation of automated control systems for the magnetic gravity separation process based on designing digital models adapted for introduction into the plant’s automated process control systems.
SOUND OF ‘LOFI’ IN THE SUBTROPICAL AFTERNOON: OKINAWAN RYUKYU KAREN IN THE VIEW OF ART THERAPY AND WELL-BEING
Authors: Wan Huang
Published: October 2023

Ryukyu karen is a relatively new 13-string musical instrument designed by Komesu Seijiro from Okinawa in 2003. Similar to Okinawan sanlele, it hybridizes taishōgoto, Western guitar, and Okinawan sanshin, embodying Okinawan cultural spirit of ‘chanpuruu’. This paper is based on fieldworks and research that existed, in the views of ‘art therapy’ and ‘anthropology of the good’ , and argues that its soothy melody, swinging rhythm, natural soundscape, chords and prolongation sound, rich layers, and clean timbre collectively create a sense of atmosphere, which has been increasingly used in therapeutic practices in recent years. Especially, the intimacy of group musiking, the easy-to-perform, and the social space of public performance enable the disabled and elder minority, who have been exclusive from marginalization. Just like the word karen, which literally means lovely, can be interchanged with Renge (lotus), its sound is metaphorized as joy and sorrow of life with healing power beyond entertainment.
Utopia and paternalism in agrarian Russia: Traditions and modernity. Part II: The 1930s – present day
Authors: Kozlov Sergey Alekseevich
Published: October 2023

This paper is the second part of the publication: Kozlov S. A. Utopia and paternalism in agrarian Russia: Traditions and modernity. Part I: The late 17th century – the 1930s // Manuscript. 2023. Vol. 16. Iss. 3. In the first part, the author presented a detailed analysis of the relationship between the phenomena of utopia and paternalism in the history of agrarian Russia in the late 17th century – the first third of the 20th century. This work will pay attention to the features of the evolution of utopian and paternalistic tendencies during the Soviet and post-Soviet periods and also outline possible directions for realising the potential of paternalism and utopia within the framework of current modernisation in Russia. As a result, the author concludes that in the context of the socio-cultural situation in modern Russia, paternalism and the understanding of the supreme power as the main guarantor of security and further development of the country have been preserved, while utopia as an important phenomenon in the socio-cultural and spiritual life of the people has practically disappeared. A productive revival of utopian and paternalistic tendencies in the development of the country is possible provided their active connection with the eternal ideals of goodness, beauty and social harmony.
Functional purpose of personal proper names in expressing the nominative-predicative aspect in the literary dictema (based on English fiction)
Authors: Noskova Anna Ivanovna
Published: October 2023

The aim of the research is to describe the functional features and categorical differences of personal proper names (anthroponyms) in the construction of the nominative-predicative aspect of the literary dictema. The scientific novelty of the paper lies in the identification of the structural-textual functions of personal proper names in relation to their etymological meaning, as well as in the extended examination of the organisation of the nominative and predicative aspects of the dictema. The investigation of linguistic units within the semantic field of the dictema is conducted using authentic texts of English fiction. The paper discusses the functional features of a personal proper name as an informative and significant unit of text that serves to establish semantic connections in the seminal aspects of speech within the literary dictema. Within the framework of the dictemic approach to the study of personal proper names, typical groups of anthroponyms have been identified, which form a specific kind of nominative-predicative centre in relation to the given mental trajectory of objective reality. As a result, the research shows that the appellative bases of anthroponyms are capable not only of denoting events, which allows associating this phenomenon with the nominative part of the dictema, but also of participating in the construction of the predicative aspect, i.e., indicating the reality and unreality of actions in the author’s imagined world and directly in the interpretation of the reader.
Semantics of zero quantity in the Kabardian language: The main ways of representation
Authors: Bizhoev Boris Chamalovich , Khezheva Maryana Rashadovna
Published: October 2023

The aim of the study is to identify the main ways of representing zero-quantity semantics in the modern Kabardian language. The study is novel in that it is the first to examine and systematise in a comprehensive manner lexical, affixal, phraseological units with the semantics of zero quantity in the Kabardian language and analyse the ways of conveying the semantics of non-possession and the semantics of absence in the Kabardian language. The paper analyses the main lexical means of conveying zero-quantity semantics in the modern Kabardian language, identifies typical constructions representing zero-quantity semantics, the features of functioning and lexical composition of phraseological and paremiological units with zero-quantity semantics, examines the main word-formation means of lexemes with non-possession semantics and absence semantics. The obtained results showed that the semantics of zero quantity is implemented in the modern Kabardian language through lexical, phraseological, paremiological, word-formation means. In addition, constructions representing zero-quantity semantics, which contain a verb in a negative form, have been identified in this language.
