The paper substantiates the equivalence of determining the apparent power of a multiphase power supply system with different transmission line impedances using the Fryze-Buchholz-Deppenbrock method and on a reduced coordinate basis. Two energy-efficient control strategies for shunt active filtering in the reduced coordinate basis are proposed. The first strategy provides a unit value of the power factor, and the second strategy minimizes power losses in the transmission line while maintaining symmetry and the quasi-sinusoidal shape of the consumed currents. The advantages of using a reduced coordinate basis are a reduction in the number of sensors and key active filter regulators as well as the absence of the problem to organize the artificial grounding point for phase voltage measurements. A correction factor for the apparent power and power factor formulas was determined and verified in the presence of restrictions on the symmetrical and sinusoidal shape of the consumed currents.

The medieval romance Guillaume de Dole mentions a mysterious queen of Puglia as well as a fairy who are both remarkable embroiderers. Examining the geopolitical situation of Apulia in the 12th and 13th c., the article argues that this surprising promotion of Apulia and its supposed fairies and queens in literature is due to a genuine interest in a region hotly coveted by princes, kings and emperors, but also to the desire to move away from Arthurian romance and explore new imaginary territories.
Der Briefwechsel von Gyula Moravcsik und Franz Dölger
Authors: Juhász Erika
Published: January 2025

The letters from the German Byzantinologist Franz Dölger (editor-in-chief of Byzantinische Zeitschrift), informative documents on the history of the period and of contemporary science, occupy a special place in the legacy of Gyula Moravcsik kept in the Manuscript Archives of the Hungarian Academy of Sciences. They give a shocking picture of the losses suffered during World War II, but also of the chaos following its conclusion. There are also many references to the post-war fate of individuals in the emerging status quo. We can gain insights into the private lives of the two families, but thanks to the close friendship between them, we can also glean valuable information about the development of both Hungarian and international scholarship in the field of Byzantine Studies.

Alloys based on titanium nick elide are widely used in medicine as implants. Nichrome wire has gained particular popularity, it is used to manufacture mesh implants used in working elements for orthodontic devices, artificial ligaments for tendon ruptures, etc. However, before manufacturing products from titanium nick elide wire, the latter is subjected to heat treatment to give the desired shape during the compression process. Many works are devoted to the study of annealing of wires more than 1 mm thick, so the purpose of this work will be to present the results of studying the structure and mechanical properties of titanium nick elide wires with a diameter of 100 μm, annealed at 300, 400, 500, 600 °C. The deformation behavior of the wire was studied after tensile strength tests. The obtained tensile curves describe its mechanical properties and super elasticity. The fracture surface of the wire was examined on a scanning electron microscope with an energy-dispersive X-ray analyzer. Fractographic analysis of the main fracture characteristics was also performed. It was found that the tensile strength and martensitic shear stress decrease with increasing annealing temperature. The annealing conditions determined by the obtained results do not suppress the super elasticity of the wire, but impart strength and ductility necessary for medical purposes. Wire samples annealed at 300 and 400 °C demonstrate similar super elastic behavior in cyclic tests characterized by mechanical hysteresis and 1 % residual deformation. Annealing of 100 μm thick wire at 500 and 600 °C provoked greater residual deformation after cyclic tests.
Effect of blood rheological propeties on the formation of recirculation zones behind of coronary artery stenosis
Authors:   Ural Federal University named after the First President of Russia B.N. Yeltsin, Makhaeva Kseniya
Published: January 2025

The present study is devoted to the investigation of the influence of blood rheological properties on the features of recirculation zone formation in hemodynamic flows near coronary artery stenosis. The Newtonian model and the Carreau model were used to describe the dynamic viscosity. Calculations were performed for an ideal 2D vessel with double and single stenosis, each of which had a degree of overlap of 50–80 %, and for a 3D model of a real coronary artery with a stenosis of 50 %, which was reconstructed from X-ray data. On the example of 2D vessel model the formation of recirculation zones after stenosis was theoretically substantiated by methods of mathematical and computer modeling. The formation of stationary vortex regions significantly depended on the blood model used. The relationship between the characteristics of the blood flow recirculation phenomenon and local and general hemodynamic characteristics is shown. To demonstrate the relationship between the rheological properties of blood and the characteristics of the phenomenon of blood flow recirculation on more complex vessel geometries, similar computer calculations were performed for a three-dimensional model of a real coronary artery. Comparative analysis of the Newtonian model and the Carro model showed that the non-Newtonian behavior of blood significantly affects such hemodynamic characteristics of blood flow as viscosity, pressure, shear stress and shear rate. A significant difference in the obtained results is shown in the case of high flow velocities. It was concluded that the Newtonian blood model can be used only in vessels with minimal disturbances in the blood flow pattern.
Additive manufacturing and numerical modeling polymer stents
Authors:   Perm National Research Polytechnic University, Sporysheva Daria , Khairulin Aleksandr
Published: January 2025

Biodegradable stents are one of the promising trends in cardiology with a number of advantages over metal stents. Studies show that these stents can effectively restore the vessel lumen and at the same time dissolve organically in the body tissues, minimizing the risk of complications. The production of biodegradable stents by FDM-printing allows to diversify the types of fabricated structures and is also an economically advantageous solution.
Numerical modeling of the expansion process of 6 stent geometries was performed. A biodegradable polymer, polylactide (PLA), was used as the stent material. The maximum expansion at the ends was achieved by stent no. 2 with five-element struts. However, in the central region, the best expansion is obtained by stent no. 4 consisting of nine-element struts. The minimum and maximum stresses of the structures are 77.1 and 83.1 MPa, respectively. In all stents after unloading, the transition to the zone of plastic deformations in the crown and link regions was revealed (max = 0.65, min = 0.1). Based on the modeling results, the coefficients of radial elasticity, shortening and unevenness of stent opening were calculated. A comparative analysis of the influence of the stent wall thickness on its ability to expand and maintain its stress-strain state was also performed, which showed that stents with 0.4 mm thickness, in contrast to 0.2 mm thickness, expand better and retain a significant opening after the load is removed from the stent.
Development of biomechanical modeling subsystem for the medical decision support system in traumatology and orthopedics
Authors:   Saratov State University, Bessonov Leonid
Published: January 2025

Clinical recommendations for the treatment of diseases and injuries of the musculoskeletal system approved by the Russian Ministry of Health indicate the need for preoperative planning. Modern approaches imply the use of digitalisation tools in preoperative planning: starting from digital software and hardware complexes of radial diagnostics and ending with medical planning software that allows for radiometric measurements, selection of fixation structures and implants, virtual repositioning and installation of implant templates. Planning on radiographs or computed tomograms is based on the experience of the surgeon and, in terms of quantitative evaluation techniques, involves mainly techniques based on known anatomical relationships of normal anatomy and physiology. A number of papers have proposed an approach to preoperative planning that includes biomechanical support for physician decision making. This approach is based primarily on the assessment of the stress-strain state that will occur in the system ‘bone - implant’ as a result of the planned treatment. This paper presents the results of the development of the biomechanical modelling subsystem of the medical decision support system in traumatology-orthopaedics. Computer tomography data are taken as initial data. Computer tomograms are processed by means of artificial intelligence technologies for construction of solid-state models of biological objects. The methods of computational meshes construction by means of Ansys and NetGen systems and biomechanics problem solving by means of finite element method of Ansys and NGSolve packages are applied. The developed subsystem partially automates the procedure of building the solid model of the system ‘bone – implant’ on the basis of computer tomogram, allows to perform the statement of the biomechanics problem, computational grid construction, numerical solution of the biomechanics problem by the finite element method, as well as visualisation and interpretation of the calculation results. The paper describes step-by-step a typical procedure of biomechanical modelling, presents the system structure, typical data flow and description of each of the subsystem modules responsible for the corresponding stages of the process. In addition to the main modules, infrastructure modules responsible for data storage and organisation of interaction between software com-ponents are described. The software implementation of the subsystem is presented. Approbation on calculation tasks in spine and pelvic surgery is carried out.

The article outlines an approach to quantify the change in human perception of virtual reality (VR). VR systems have made significant progress, reducing the impact of their errors. Changes in postural characteristics are particularly distinct in tests where visual information is used more actively, such as when a person balances on a compliant surface. A series of tests were conducted where subjects maintained a vertical posture while standing on a hard force plate. During the tests, the subjects stood on both a regular hard surface (the force plate) and a compliant surface made of polyurethane foam. Maintaining balance on the compliant surface complicates the control task and requires the mobilization of human sensory systems, leading to an increased reliance on visual information. While maintaining posture, the subjects either looked at an image placed on the wall at eye level on a plain background or viewed the same image using virtual reality hemlet. During the examination with VR hemlet, the VR software used coordinates data, orientation and information from the VR helmet inertial sensors to reproduce a stationary environmentimage. For the current sample of volunteers tested on a compliant surface, stabilometric parameters with a stable tendency to change were identified: the average speed of the centre of pressure, an indicator of the quality of the equilibrium function, and the normalised area of the vectorogram. No noticeable changesrelated in the type of support in oculographic data were observed. Noticeable changes in oculographic data were also noted, however, the errors in their determination associated with the discrepancy between the frequencies of oculographic measurements allow us to draw only a preliminary conclusion on this issue.

Published: January 2025

Breast augmentation with silicone implants is one of the most common aesthetic procedures. Rupture of the implant is the main reason for repeated surgery and for the removal of the implant. The aim of the study is to investigate the changes in toughness and deformability of the shell of breast implants leading to their rupture depending on the conditions of mechanical loading. The methods of continuum mechanics utilized to model the behavior of elastomers are used. Cyclic stretching and cyclic stretching with increasing amplitude were performed on implant shells from different manufactures, and mechanical tests on Eurosilicone, Mentor and Motiva implant shells. The initial sections of the stress-strain curves up to 200 % are shown for the Mentor (8 year function), Eurosilicone (8 year function) and Motiva (2 year function) shells. The obtained experimental results are compared with the data for the unused (control) implant shell. The cyclic stretching test data show that, after the first elongation to a given strain, the implant shell softens and the next stress-strain curve is much lower than the first. At a strain greater than the previous strain, the stress-strain curve returns to the initial curve of the unstretched specimen. In the presence of microdamage, the shells of breast implants soften (Mul-lins effect), and the curves fall below the curve of the control test. It is shown that the implants lose some of their strength over time due to microdamage accumulation at systematic cyclic strain in the range of 100–130 %. At large deformations, the implant strength decreases significantly, and rupture of the implant can occur much earlier than its shelf life.

Authors: Ameur Imane
Published: January 2025

Aim: This article aimed to determine the effect of macroeconomic and specific variables on the ratio of non-performing loans, and study the recursive direction of bank profitability to NPLs in Tunisian banks. Methodology: To formalise this phenomenon, the author proposed a panel data model that covers a sample of ten listed Tunisian banks over a period from 2007 to 2015. Findings: The empirical results indicate the determining power of bank profitability measured by asset profitability, solvency ratio, credit growth rate, provision-based debt coverage rate, bank size, inflation and unemployment. Implications: The effect of these variables veered between the preservative and destructive aspects of the quality of bank assets. Originality/value: This study enabled not only to identify the explanatory factors of this phenomenon, but also to verify the existence of a simultaneous relation between NPLs and bank profitability.

Authors: Kaweesi Ronald , Chikafalimani Samuel HP , Musinguzi Moses
Published: January 2025

Despite several developing economies enacting REIT regulations, REITs are still underutilised as an alternative vehicle to address the current real estate financing challenges especially for non-traditional real estate asset classes such as agricultural real estate. The limited research on the application of REIT for financing agricultural real estate further complicates the situation. Thus, an inquiry into the readiness of REIT connected parties as stipulated by the regulation for the implementation and facilitation of REITs is vital. The study aims to explore the readiness of REIT connected parties towards the implementation and facilitation of REIT for agricultural financing in Uganda. The study employs a qualitative phenomenological study approach to describe the readiness of connected parties through their lived practice experiences. Data collection is conducted by interviewing a purposively selected sample of potential REIT connected parties based on their involvement in the finance and investment sector. Knowledge, skills and abilities (KSA) themes are analysed from the interview notes and the connected parties` readiness gaps are discussed in the discussions.

Assessment of the quality of life using validated questionnaires is a modern and effective tool for identifying psychological and pedagogical problems. The aim of the study was to analyze the quality of life of adolescents studying in a secondary comprehensive school. Materials and methods: The study was conducted using the PEDsQL 4.0 questionnaire (Pediatric Quality of Life Inventory version 4.0) among 139 students aged 15-17 (68 girls - 48.9%; 71 boys - 51.1%) and their families. Children's and parents' versions of the questionnaires were analyzed. Statistical analysis of the data was carried out using nonparametric statistics. Results: Among schoolchildren, a high level was noted on the social functioning scale and low scores on the emotional functioning scale, indicating poor emotional-volitional functioning of adolescents. Analysis of parental questionnaires noted a low number of points on the Life at School scale, indicating parental concern about the adaptation of adolescents to academic workloads. Evaluation of the correlation of children's and parents' versions using the Spearman rank correlation method showed statistically significant differences in the scales of physical and emotional functioning (p<0.01) and the scale "Life at school" (p=0.012). Gender differences in the assessment of physical and emotional functioning were revealed, with a higher level among young men (p<0.001). Paired comparison of age groups (15, 16 and 17 years) according to children's versions using the Mann-Whitney criterion did not reveal statistically significant differences. Conclusion. Analysis of the quality of life of schoolchildren is a valuable way to diagnose problems in various types of functioning. Evaluation of the quality of life of adolescents studying in a general education institution identified a number of problems for subsequent individual psychological and pedagogical correction.

Published: January 2025

Abstract International organizations have sought to integrate gender issues into the sustainable development agendas of nations, guiding the elaboration of gender-focused public policies. Despite global efforts promoted in recent decades to eliminate inequalities between women and men, recent reports indicate that there is still much to be done, suggesting the incorporation of this perspective in government planning instruments as fundamental to achieving effective results in the medium and long term. The study carried out in the city of Belo Horizonte sought to assess whether the city’s budgetary planning instruments showed increase in gender-sensitivity following the launch of the Municipal Gender Equity Plan in 2019. The analysis revealed that the plan’s guidelines were not properly incorporated, highlighting the difficulties related to its breakdown into budgetary actions.
Overeducation among Affirmative Action Beneficiaries: Evidence from a Brazilian Public University
Authors: Soares Ana Maria Jerônimo
Published: January 2025

Abstract This study analyzes whether beneficiaries of an Affirmative Action (AA) bonus at the Federal University of Rio Grande do Norte (UFRN) are, after graduation, entering the labor market in occupations aligned with their qualifications or if they are experiencing overeducation - having more schooling than required for the exercise of the professional activity. To this end, administrative data on admissions to UFRN were cross-referenced with information on formal workers registered in Brazil, available in the Annual Social Information Report (RAIS). The Regression Discontinuity Design (RDD) method was used as an identification strategy. Among the main results, it is noteworthy that women admitted through AA to UFRN have a higher probability of completing the program. In contrast, men in the same situation are more likely to experience overeducation, indicating a greater mismatch between their education level and professional occupation, highlighting gender discrepancies in the effects. The conclusions suggest the need for additional policies and programs that promote academic and career guidance and encourage cooperation between universities and the job market, facilitating the transition into roles that match graduate’s education level.

Published: January 2025

ABSTRACT: The chemical characteristics of lignocellulosic biomass determine its suitability as an energy source, affecting its combustibility, flame stability, and overall energy efficiency. Therefore, this study assessed the correlation between the chemical characteristics and higher heating value (HHV) in Eucalyptus biomass components (wood, bark, branches, and leaves) of three species (E. benthamii, E. dunnii, and E. saligna). The results revealed varying chemical compositions among the components and species, which impacted the HHV differently. Notably, volatile materials positively influenced the HHV, whereas excessive ash content negatively affected the energy potential. Positive correlations with HHV were observed for the total extractives content in the bark, total lignin content in the leaves, volatile materials content in the bark, leaves, and stem, and fixed carbon content in the stem. Conversely, the holocellulose content reduced the bark HHV. Volatile materials, except in the branches, efficiently increased the HHV. None of the chemical characteristics had a significant impact on the branches HHV.

Published: January 2025

ABSTRACT: Cutaneous adverse drug reactions (CADR) are unexpected dermatological reactions caused by medications. CADRs may mimic any type of dermatosis, including contact dermatitis (CD). This paper described a case of a CADR resulting from the topical use of benzyl benzoate in a dog. A two year old unneutered male Pit Bull was referred for a medical consultation due to skin lesions in the cervical region. The owner reported bathing this dog routinely using 10% benzyl benzoate (BB)-based scabicidal soap, without rinsing it off at the end. An ulcerative, draining maculopapular skin lesion was observed in the dorsal region of the neck extending to the interscapular region. A surgical skin biopsy was then performed and microscopically an area of ulcerated epidermis was observed with apoptosis of transepidermal keratinocytes associated with a mixed infiltrate. Interface dermatitis with a predominance of lymphocytes in the hair follicle region, multifocal areas of mild spongiosis, mild vacuolar degeneration of keratinocytes and sub-corneal pustule was also identified. Bathing with the BB-based scabicidal soap was discontinued and a new shampoo was introduced. Topical dexamethasone, neomycin sulfate, bacitracin zinc, griseofulvin, and benzocaine treatment was started. Within 48 hours of treatment, skin revitalization was already significant and total healing took place approximately three weeks after the first appointment. Considering the findings observed in this case, it can be concluded that prolonged topical exposure to BB, due to misuse of the product, may cause a CADR characterized by irritant CD in dogs.

Published: January 2025

ABSTRACT An increasing amount of waste is being disposed of as a result of growing industrialisation, endangering the environment. In the building industries of all the fly ash-producing nations, fly ash is used in structural and non-structural concrete in a variety of ways. Practically, high-volume flyash consumption is a significant advancement. Thus, an inquiry into high calcium fly ash-based geopolymer composites is started through this investigation, using class C fly ash obtained from the Thermal Power Station of Neyveli Lignite Corporation as a quantum waste. Geopolymer composites with diverse molarities for M30, M35 and M40 were experimented with characteristics of compressive, split tensile, flexural, water absorption, and rapid chloride ion penetration tests and correlated with standard concrete. The outcome established that a geopolymer composite with 12 molarity blended with crushed stone sand and pond ash bottom ash recycled coarse aggregate salvage marble coarse aggregate was optimal in characteristics. Investigation reveals that water absorption is relatively minimal in geopolymer composites compared to standard concrete. RCPT shows the geopolymer concrete has excellent chloride resistance over prolonged curing time. This study sees an opportunity to evaluate the effects of employing alternatives for both fine and coarse materials. Here, fly ash completely replaces the cement.

Abstract Aim To evaluate the clinical effectiveness of ozonated sunflower oil (Oz) as an adjunctive of non-surgical periodontal therapy in patients with type 2 diabetes mellitus (DM2), on fibroblast cell viability and migration and the effectiveness of Oz on a Candida albicans (C. albicans) culture. Methodology In total, 32 sites in 16 DM2 with moderate to advanced periodontal disease with periodontal pocket depths ≥5mm were selected. The treatments were divided into two groups: control, saline solution (SS) as an adjunctive of scaling and root planing (SRP+SS), and test, Oz as an adjunctive of SRP (SRP+Oz). Hematological [fasting glucose level (FGL) and hemoglobin A1c (HbA1c)] and microbiological samples were collected from the participants at baseline and three months after periodontal treatment and the microbiological samples were analyzed by PCR. C. albicans was previously tested by the agar diffusion test. The effect of Oz was tested on cell viability and fibroblast migration. Results The groups showed no statistically significant differences (paired t-test-p>0.05) regarding hematological parameters, FGL (median - baseline 171.41, 3 months 164mg/dL), and HbA1c (baseline 8%, 3 months 7.5%) (Kruskal-Wallis One-Way Nonparametric-p>0.05) after periodontal therapy. The groups showed statistical differences for periodontal parameters between baseline and three months (paired t-test-p<0.05). PCR analysis showed a reduction in the percentage of C. albicans in the SRP+Oz group after three months (McNemar’s test-p=0.002). Cell viability was lower in the high glucose Dulbecco’s modified Eagle’s medium (4500 mg/L) than in low glucose (1000 mg/L) (RM-ANOVA-p<0.0001). The wound healing test showed reduced fibroblast migration (one-way ANOVA with Dunnett’s post-test-p<0.01). Oz showed high C. albicans antifungal inhibition (Kruskal-Wallis test-p=0.0001). Conclusions SRP+Oz effectively reduced C. albicans in-vitro and in-vivo but showed no clinical improvements compared to the control. Cell viability and wound healing of fibroblasts showed no improvements.

ABSTRACT Considering the high importance of maize as a subsistence crop and the need for optimal use of water resources in semi-arid regions, this study aimed to evaluate the agronomic potential, heterosis, and heterobeltiosis within different genetic categories of maize hybrids grown in a semi-arid region in Sergipe, Brazil, under rainfed and wastewater irrigation systems. Ten maize genotypes, their 45 hybrid combinations, and five commercial genotypes as controls were evaluated based on plant height, ear height, and grain yield. Positive heterosis and heterobeltiosis were found under both growing environments for hybrids H1, H13, H16, H32, H35, H5, H8, and H9. Genotypes P2, P3, and P9 were identified as potential parents for the development of new hybrid maize varieties for growing in the semi-arid region of Sergipe. Better agronomic performance was found for the wastewater irrigation system, indicating an excellent strategy for maize production under semi-arid conditions. The hybrids formed by the combination of variety × intervarietal hybrid [F1 (P1 × P2), F1 (P1 × P5)], variety × single hybrid [F1 (P2 × P6), F1 (P2 × P9), F1 (P5 × P7), and F1 (P5 × P10)], intervarietal hybrid × single hybrid [F1 (P1 × P6) and F1 (P1 × P9)], and double hybrid [F1 (P1 × P10)] indicate promising hybrid candidates for maize crops in semi-arid regions.

Abstract Although it is recognized that periodontal disease negatively impacts quality of life, there is no validated instrument to assess this impact in Brazil. This study aimed to translate, cross-culturally adapt, and validate the OHIP 14 PD (Oral Health Impact Profile Applied to Periodontal Diseases) for application among Brazilian patients. The original instrument was translated and validated into Brazilian Portuguese in a cross-sectional study with 110 participants recruited from a Dental School clinic. The sample was divided into two groups: 55 with periodontal disease and 55 without periodontal disease. The instrument was self-administered twice within an interval of 7 to 10 days for patients with periodontal disease. The psychometric properties of the Brazilian version were verified using internal consistency (Cronbach’s α) and the reliability through the test-retest method (ICC, intraclass correlation coefficient), convergent validity (Spearman correlation), and discriminant validity (Mann-Whitney test), with p <0.05. Most of the sample consisted of women (n=69; ±40.65 years). The OHIP 14 DP - Br showed excellent internal consistency (α=0.997) and outstanding reliability using the test-retest method (ICC=0.945, p<0.001). There was a significant correlation between the scores obtained in all seven domains between this questionnaire and self-perceived gingival health (p=0.023). This study provides psychometric evidence supporting the cross-cultural validity of the OHIP 14 DP - Br version for use in Brazil.

Abstract This study aim was to evaluate the need for orthodontic treatment of mixed to permanent dentition using the Dental Aesthetic Index (DAI) in a 4-year follow-up. A longitudinal study was conducted with 353 children in the stages from mixed (T1) to permanent (T2) dentition. The need for orthodontic treatment was assessed using the DAI categorized into: DAI 1 (absence of malocclusion and orthodontic treatment need; DAI ≤ 25); DAI 2 (malocclusion is defined and elective orthodontic treatment is needed; DAI = 26 to 30); DAI 3 (severe malocclusion and a desirable orthodontic treatment need; DAI = 31 to 35) and DAI 4 (severe malocclusion and a mandatory orthodontic treatment need; DAI ≥ 36). The Bowker symmetry test was used to determine agreement in the categorization of DAI at T1 and T2, with a significance level of 5%. The results showed a significant disagreement in the need for orthodontic treatment between T1 and T2 (p<0.05). In 34.6% of children evaluated in T1, the same need for orthodontic treatment was maintained in T2. According to the DAI, in 60.8% of the children, the need decreased, and in 39.2% their need for orthodontic treatment increased. This preliminary longitudinal study using DAI, showed a decrease in malocclusion and need for orthodontic treatment as the dentition transitioned from mixed to permanent occurred. This finding has valuable implications for epidemiological data in orthodontics.
