Authors: Haijuan Li , Ponomarova Nataliia
Published: December 2024

The article provides an overview of the use of specialized Internet resources in music-pedagogical education for the professional training of future music teachers in Ukraine and China. In Ukraine, higher education institutions utilize a wide range of specialized Internet resources, with a preference for non-commercial ones. These resources are effectively integrated into the educational process, used for teaching professional and methodical disciplines, facilitating educational and research work, and encouraging independent creativity among students. Digital and specialized Internet resources are recognized as a key aspect of modernizing the educational process in all higher musical and pedagogical institutions. However, challenges, such as the absence of Ukrainian localization in popular projects and inadequate technical support in educational institutions, complicate the use of these resources. Additionally, using Internet resources with artificial intelligence is in the early testing and active discussion stage in Ukraine. In China, alongside international Internet resources (limited due to national requirements), a wide range of localized or adapted Internet resources is utilized in music-pedagogical education. These specialized Internet resources are primarily used in teaching special educational disciplines of the professional training cycle. The systematic use of artificial intelligence in musical and pedagogical education in China is particularly noteworthy. The technological advantages of using specialized Internet resources in the training of future music teachers have been established, including accessibility and cross-platform compatibility, real-time updates, less need for device resources, deployment speed and scalability, instant access and ease of use, saving memory on the user's device, simplicity in support, and security. These advantages have implications for the methodological features of their use in music and pedagogical education, which require further research

RATIONALE OF TECHNOLOGY OF MASHING OAT MALT FOR THE PRODUCTION OF GLUTEN-FREE BEER
Authors: Kosiv R.
Published: December 2024

The article is devoted to the substantiation of the technology of mashing oat malt for the production of glutenfree beer. Oats are a promising raw material for the production of products with functional properties due to their rich chemical composition and high nutritional and biological value, as well as their good acceptance by consumers, including those suffering from celiac disease. On the other hand, oats are a cereal crop with unrealized brewing potential. The use of oat malt for beer production can be innovative but also challenging. It has been found that oat malt is characterized by properties different from barley malt. The increased content of ?-glucan in oat malt causes difficulty in filtering intermediate products and finished beer. Due to the low activity of ?-amylase in oat malt, the duration of starch saccharification is prolonged, resulting in lower extract yield and lower degree of fermentation. The increased protein content in malt can cause a decrease in the stability of beer during storage. To eliminate the difficulties encountered in the processing of oat malt and to obtain wort with the required carbohydrate and nitrogen composition, it is proposed to use complex-action enzyme preparations Alphalase Sorghum, Alphalase AP3, Diazyme FA (Danisсo, Denmark), which are optimized mixtures of ?-amylase, ?-glucanase, and protease. The complex enzyme preparation reduces the viscosity of the mash and facilitates its filtration, while increasing the wort yield and making it easier to filter finished beer when using the membrane method. When adding an enzyme preparation of complex action, the viscosity of wort decreases, since the preparation effectively breaks down ?-glucan, starch and pentosans. The temperature regime for mashing oat malt by the infusion method using an enzyme preparation of complex action, developed taking into account the technological properties of oat malt, is recommended. The use of atypical malted raw materials in brewing ? oat malt ? can give beer completely new organoleptic properties, which is another advantage of gluten-free oat beer.
O desenvolvimento local em contextos territoriais de contração: contributos para um modelo de análise
Authors: Machado Cruz Bernando , Costa Pedro
Published: December 2024

Neste artigo elabora-se uma análise, essencialmente conceptual, sobre as estratégias de desenvolvimento e os desafios enfrentados por territórios “em contração”, procurando partir de uma compreensão alargada dos fatores que explicam a configuração espacial na atual fase do capitalismo. Por um lado, revisita-se a literatura sobre o desenvolvimento regional e local, procurando questionar a evolução geral das teorias e políticas de desenvolvimento, designadamente à escala local e regional. Por outro lado, explora-se a literatura que procura compreender as dinâmicas que explicam a distribuição espacial da atividade humana e o crescimento das cidades, atentando à configuração geográfica da economia do conhecimento, procurando a partir daí identificar as particularidades das condicionantes ao desenvolvimento dos territórios em contração. Do confronto destas duas revisões de literatura, e procurando uma compreensão articulada dos principais contributos de ambas, procura-se perceber a relação teórica e conceptual entre desenvolvimento local, contração territorial e qualidade vida. Este exercício tem como objetivo a identificação dos limites de aplicação geográfica dos modelos de desenvolvimento contemporâneos, e achar novos princípios orientadores da atuação dos agentes nos territórios em contração. Como resultado desta análise, julga-se vantajosa a adoção de estratégias de desenvolvimento beyond growth, centradas na valorização intrínseca das esferas não económicas do desenvolvimento. Assumindo a centralidade da ideia de qualidade de vida e a diversidade de fatores que contribuem para os processos de desenvolvimento e de contração territorial, importa valorizar os atributos qualitativos dos lugares, bem como os fatores relacionais e afetivos do território, reconhecendo a sua relevância nas decisões locativas das pessoas.

This work is devoted to experimental and theoretical studies of the sputtering of electrodes in an arc discharge. The temperature distribution in the working chamber during arc discharge is analyzed depending on the discharge current. On the basis of experimental data on the anode sublimation and interelectrode distance, a fan jet is simulated, which is generated during the anode sputtering in an arc discharge. The calculation is carried out using the model describing the processes occurring in the arc plasma, jet propagation, transport of particles by the jet and their ionization. The numerical simulation results for the radial temperature distribution are consistent with the experimental data. The experiments show that an increase in the discharge current leads to an increase in the concentration of fullerenes and graphite structures in the soot. Based on the simulation data, it is shown that this effect is a result of the longer residence time of growing carbon particles in a high-temperature zone (1000-2800 K) at high arc discharge currents. The authors acknowledge the Core Facilities VTAN at NSU for the usage of experimental equipment.

For grinding and fractionation of submicron and nanosized powders, pneumatic methods with the use of built-in centrifugal-type separation elements of various designs are currently the most promising. In these devices, it is possible to most effectively provide the aerodynamics of the dust and gas flow in the separation zone, which allows one to control the separation boundary. In a fluidized bed apparatus, the layer extends to the rotor. The particles are affected not only by gravity and flow forces but also by the forces arising from the rotor impact on the flow. This paper considers the separation effects associated with the classification of fine powders. Experimental data on the circumferential air velocities near the rotor surface are obtained as the functions of the rotor rotation number. The high-speed interactions of solid particles in a pneumatic grinder with a fluidized bed are evaluated. Using the obtained aerodynamic experimental data, the boundary size of the separated particles is calculated. A comparison of the calculated boundary size of TiN ceramic particles with the obtained experimental data on the fractional separation of fine TiN powders based on granulometric composition measurements by laser diffraction is presented.

This paper investigates a numerical model of non-stationary fluid filtration in the vertical well vicinity after a short-term disturbance of a formation taking into account the skin effect and wellbore storage effect. The numerical solution to the problem is compared with an approximate solution to the Muskat problem, which is obtained by the method of sequentially changing stationary states. The influence of formation permeability and skin factor on the bottomhole pressure build-up is studied. The wellbore storage effect has been shown to completely mask indications of the bottomhole zone. For low-permeability formations, the pressure build-up process is time-consuming. Hence, the flow-over techniques should be used to investigate them. A method for interpreting pressure-transient data based on the theory of solving ill-posed inverse problems is proposed. The method determines the formation permeability, skin factor, and formation pressure values using the measured bottomhole pressure profile after a short-term disturbance of the formation. Estimates of the well productivity index and formation pressure are in good agreement with those obtained using the integral and Muskat methods. In contrast to the methods based on the Muskat solution, the proposed method allows the assessment of the skin factor.

Bu araştırmada, çalışma sırasında kavitasyon olayına maruz kalan gemi pervanelerinde tercih edilen Mangan Alüminyum Bronz (MAB-CU4) malzemesinin kavitasyon aşınması davranışında etkili olan farklı parametreler incelenmiştir. Çalışma, özellikle bu parametrelerin yüzey pürüzlülüğündeki (Ra) değişimi nasıl etkilediğine odaklanmıştır. Verileri analiz etmek için Taguchi deneysel tasarımı kullanılmıştır. Bu özel bağlamda, MAB-CU4 alaşımının kavitasyon erozyonu özellikleri mevcut literatürde yalnızca asgari düzeyde araştırılmıştır. Bu kapsamda çalışma, kavitasyon sayısı, hücum açısı ve mesafe gibi çeşitli parametreler dikkate alınarak yüzey pürüzlülüğü etkisinin ilk kapsamlı incelemesini temsil etmektedir. ASTM G134-95 standartlarında belirtilen özelliklere uygun olarak kavitasyon erozyonu deneyleri için yüksek basınçlı kavitasyon su jeti test cihazı tasarlanmış ve üretilmiştir.

Çift yakıtlı dizel motorunda ikinci yakıt olarak etil asetat kullanımının motor performansı ve egzoz emisyonları üzerindeki etkisi
Authors: Çelik Hasan Ali
Published: December 2024

Bu çalışma, çift yakıtlı bir dizel motorda ikincil yakıt olarak etil asetat kullanımının motor performansı ve egzoz emisyonları üzerindeki etkilerini araştırmaktadır. Deneyler, çeşitli yükler (%0, %25, %50, %75 ve %100) altında sabit 1800 d/d motor hızında çalışan bir dizel motor kullanılarak gerçekleştirilmiştir. Standart dizel yakıt enjeksiyon sistemine ek olarak, etil asetat emme manifolduna 1 ms, 2 ms ve 3 ms'lik değişen enjeksiyon süreleriyle enjekte edilmiştir. Ölçülen parametreler arasında tork, özgül yakıt tüketimi (ÖYT), toplam enerji tüketimi (Etotal), egzoz sıcaklığı ve CO, HC, CO2, O2, NOx, Lambda, is ve emisyon ölçümleri yer almaktadır.
Tam yükteki test sonuçları, %100 dizel yakıtla yapılan temel ölçümlerle karşılaştırıldığında önemli değişiklikler ortaya koymuştur. Özellikle, 1 ms etil asetat enjeksiyonuyla, HC emisyonları %42,86, NOx emisyonları %1,88 ve duman emisyonları %72,45 oranında azalmıştır. 2 ms etil asetat enjeksiyonuyla, fren özgül yakıt tüketimi (ÖYT) %1,28 ve CO emisyonları %51,64 oranında azalmıştır. 3 ms etil asetat enjeksiyonuyla, toplam enerji tüketimi (Etotal) %12,67 oranında azalmıştır ve belirtilen ortalama efektif basınç (IMEP) %2,89 oranında artmıştır.
Bu bulgular, etil asetatın çift yakıtlı bir dizel motorda ikincil yakıt olarak kullanıldığında yanma verimliliğini önemli ölçüde artırabileceğini ve özellikle tam yük koşulları altında zararlı emisyonları azaltabileceğini göstermektedir. Çalışma, etil asetatın çift yakıtlı dizel motorlara dahil edilmesinin potansiyel faydalarına ilişkin değerli sonuçlar sunarak, bu yaklaşımın daha temiz ve daha verimli dizel motor çalışmasına yol açabileceğini ileri sürmektedir. Enjeksiyon stratejilerinin optimize edilmesi ve etil asetatın ikincil yakıt olarak kullanılmasının uzun vadeli etkilerinin araştırılması için daha fazla araştırma yapılması önerilmektedir.
High-Precision UAV Photogrammetry with RTK GNSS: Eliminating Ground Control Points
Authors: Alkan Mehmet Nurullah
Published: December 2024

The advancements in Unmanned Aerial Vehicles (UAVs) have significantly enhanced the capability of the photogrammetric approaches, particularly with the integration of Real-Time Kinematic (RTK) sensors. That approach enables the operators to use the Global Navigation Satellite System (GNSS) more efficiently with the production of high-precision 3D Digital Terrain Models (DTMs). Traditionally, Ground Control Points (GCPs) are used to link those models to a ground coordinate system, but their establishment is time-consuming and labor-intensive, requiring static or rapid-static GNSS observations over two hours for each point. However, RTK-embedded UAVs offer a significant improvement by facilitating direct geo-referencing of DTMs, which includes the estimation of internal and external orientation parameters more efficiently and potentially eliminating the need for GCPs.
In this study, UAV flights over a test area at various altitudes (30m, 45m, 60m) were conducted to evaluate the 3D positioning accuracy of photogrammetric models generated without using any GCP, and their locations were compared against the precise GNSS observations for 22 control points. Results indicated that UAVs with RTK ability could achieve centimeter-level accuracy in positioning, making this kind of evaluation a viable alternative to traditional methods. This study also discusses the implications of those results within the context of large-scale map production and their regulations in Türkiye. The elimination of GCPs should significantly reduce the time and effort associated with map production, suggesting a potential alternative in regulatory standards to incorporate these technological approaches.
Evaluating the Combined Effects of Transverse Pitch Ratio and Flow Arrangement on the Thermo-Hydraulic Performance of a Novel Inclined Delta Winglet
Authors: Demirağ Hüseyin Zahit
Published: December 2024

In this work, the in-depth examinations of the Novel Inclined Delta Winglet (NIDW) in terms of heat transfer performance and the flow characteristics are conducted at Re=5000-17500, utilizing (SST) k-ω turbulence model. In accordance with the objective of this investigation, the combined effects of the positioning of the NIDW in common-flow-down (NIDW-CFlowD) and common-flow-up (NIDW-CFlowU) orientations together with two transverse pitch ratios [Pt=0.333 and 0.166] are investigated and the resulting data are presented in a comparative manner. The angle of attack [α=30°] and the angle of inclination [β=30°] of the NIDW are kept constant. The numerical results indicate that the NIDW-CFlowD orientation at Pt=0.333 has more pronounced effect in terms of thermal performance, with an approximate increase of 4.29% increase in the Nusselt number at Re=17500, whereas the opposite trend is observed at Pt=0.166, yielding a smaller rise of around 3.13% in Nusselt number at Re=17500. The reversal in trend is entirely due to the positioning of the NIDW in the CFlowD orientation, which causes the vortex rotation centers to move further apart in the main flow direction, resulting in 4.36% and 4.02% higher Darcy friction factors in cases of Pt=0.333 and Pt=0.166, respectively compared to CFlowU configuration at Re=5000. Therefore, the highest and lowest ranges of Thermal Enhancement Factor (TEF) are calculated to be between 1.325-1.215 and 1.221-1.122 for the cases of NIDW-CFlowU with Pt=0.166 and NIDW-CFlowU with Pt=0.333 respectively. This corresponds to an increase in TEF of around 8.52%and 8.30% increase in TEF at Re=5000 and 17000, respectively.
La maldición del comentarista en el pádel: estudio de caso sobre los atractores y las cadenas de Markov
Authors: González Fernández Marcos , Cañellas Trias Martí , Lacasa Claver Enrique
Published: December 2024

This study presents an approach to analyzing padel player behavior from the perspective of complex systems and dynamical systems theory. Using the Markov model of change, we identify the attractors or stable states of behavior that influence player performance in a competitive context, providing valuable information to design more effective strategies and training. Using data obtained from the World Padel Tour competition and the Markov change model, we quantify the behavioral patterns of a top five in the world ranking player by analyzing his strokes and his positions on the court. A sport of cooperation and opposition in alternative space and time implements, glass and fences, or outdoor play, such as the one that characterizes padel, involves a high demand for continuous player adaptation to a variable context. With the Markov model, we were able to identify the behavioral attractor states of the player in serving, returning, in each area of the court, and after the opponent hit a lob. As a conclusion, despite the impossibility of predicting the players' behavior with accuracy, the Markov model can help us understand the dynamics of player behaviors and whether there are competitive contexts that foster certain stable states.

This study examines the effects of nutritional education given to individuals diagnosed with cancer anorexia cachexia syndrome (CACS) on serum irisin levels, cachectic factors, proinflammatory cytokines, quality of life scale results, and anthropometric and routine biochemical parameters. Forty-one patients diagnosed with CACS were randomly divided into two groups, experimental and control. Nutrition education was given for 12 weeks to the patients in the experimental group (n=23), while those in the control group (n=18) were not subjected to any intervention. All participants’ serum irisin, proteolysis-inducing factor, zinc-α-2 glycoprotein, interleukin-6, tumor necrosis factor-α, routine biochemical parameters, and body weight were measured at the beginning and end of the study. The patients were also evaluated in terms of 24-hour recall food intake, body mass index, and quality of life scale values. No significant differences were observed at baseline between the experimental and control groups in terms of quality of life scale values, cachectic factors, inflammatory cytokines, or irisin levels. However, at the end of the study, hemoglobin levels were higher in the experimental group than in the control group. Energy and nutrient intakes were similar between the groups initially, but were higher in the experimental group at the end of the study. Nutrition education did not significantly alter the quality of life scale, BMI, or biochemical parameters. However, education yielded the expected increase in nutrient intake in the experimental group.

Authors: Ünal Asuman
Published: December 2024

Polymer composites are considered alternative material because they combine the advantages of all their components. Furthermore, polymer composites can exhibit unique electrochemical and physical properties, enabling their use in applications where metals may not be suitable. Polypyrrole, as a conductive polymer, is a promising candidate for synthesizing new composite materials due to its high electroactivity and ease of processing. Incorporating certain organic and inorganic species into polypyrrole matrices can enhance its electrochemical and physical properties. In the study, polypyrrole films were electrochemically coated in the presence of varying concentrations of sodium molybdate and sodium tungstate. The effects of these metal oxides on the growth of polypyrrole were analyzed, and the electrochemical properties of the resulting composite films were examined in monomer-free solutions. The findings indicate that molybdate and tungstate reduce film’s electroactivity, alter redox peaks, and lead to the formation of a new electrochemical film. The maximum anodic peak charge density for polypyrrole, polypyrrole/WO3 and polypyrrole/MoO4 films was 12.4 mC cm-2, 3.57 mC cm-2 and 3.14 mC cm-2, respectively. Additionally, the results demonstrated that an optimal amount of sodium tungstate enhances charge transfer while maintaining reversibility in redox reactions
A Quantum Chemical Study on the Antioxidant Properties of Myricetin, Quercetin, and Kaempferol Using Density Functional Theory (DFT) and Molecular Docking
Authors: Elik Mustafa
Published: December 2024

This study explores the antioxidant properties of myricetin, quercetin, and kaempferol using density functional theory (DFT) and molecular docking analyses. The findings of this study not only highlight the significant antioxidant potential of flavonoids and provide a foundation for potential clinical applications and future research aimed at optimizing their pharmacokinetic properties for therapeutic use. The optimized geometries of these flavonoids were determined through DFT calculations at the B3LYP/6-31G(d,p) level. Key electronic properties, such as total electronic energy (Eₜ), zero-point energy (ZPE), enthalpy (H), entropy (S), dipole moment (μ), and HOMO-LUMO energy gaps (ΔE_H-L), were computed to evaluate molecular stability and reactivity. Molecular docking with proteins 1HD2, 1RAU, 3FZS, and 3GRS revealed strong binding affinities, particularly for myricetin, which achieved docking scores of -5.330 with 1HD2 and -8.652 with 3GRS, indicating a high potential for antioxidant activity. ADME analyses demonstrated that kaempferol exhibited the most favorable pharmacokinetic profile, with a human oral absorption rate of 63.637% and compliance with Lipinski’s Rule of Five. Conversely, myricetin showed reduced bioavailability despite its strong binding affinity. This work emphasizes optimizing flavonoid pharmacokinetics to maximize their therapeutic potential while reinforcing their relevance in antioxidant therapy.
Modeling the Effect of Heat Distribution in Photothermal Therapy by Using Computational Fluid Dynamics (CFD)

Published: December 2024

Cancer is a mortal disorder around the world, and according to the World Health Organization (WHO), it is a leading cause of death, causing nearly 10 million deaths in 2020. It is commonly treated by chemotherapy, radiotherapy, and surgery. However, the undesirable effects of these treatments encouraged clinicians to find better therapies, such as photothermal therapy (PTT). PTT has been commonly used for being less harmful to the healthy tissues near the cancer cells. However, it is necessary to know that the heat distribution is suitable and that the surrounding tissue is not overheated. This work uses Computational Fluid Dynamics (CFD) to model the cancer cell and the healthy tissue around it as a 3D model using ICEM CFD, a pre-processing program of Ansys Fluent 18.2. It is found that wall shear stress is high, up to 4600 Pa in the top parts of the cell, and lower in others. The highest pressure on the cancer cell goes up to 36000 Pa in the lower parts of the cell. The results of this work could guide researchers in optimizing the photothermal therapy of cancer cells, and the modeling approach could be applied to investigate alternative therapies.

Antioxidants help prevent signs of aging and skin tone inequalities by protecting our skin from free radicals. High tyrosinase inhibition has a whitening effect on the skin, while collagenase inhibition has an anti-sagging effect on the skin. Antioxidant activity and tyrosinase/collagenase enzyme inhibition capacities have mutually supporting effects. The aim of this study was to determine the antioxidant activities, tyrosinase and collagenase inhibitory potentials of ethanol extracts of two medicinal plants from Turkey (Smyrnium rotundifolium and Euphorbia virgata). In the study, 6 different reference substances and their chemical contents were investigated. Myricetin, quercetin and kaempferol were observed in S. rotundifolium extract, and quercetin was observed in E. virgata extract. According to the antioxidant capacity results measured by both analyses; S. rotundifolium (IC50 DPPH•: 4.9±0.15 µg/mL, IC50 ABTS•+: 4.3±0.2 µg/mL) and E. virgata (IC50 DPPH•: 4.6±0.11 µg/mL, IC50 ABTS•+: 4.1±0.13 µg/mL) extracts were observed to have antioxidant capacities similar to each other. It was determined that S. rotundifolium had higher anti-collagenase (27.9±0.13% inhibition) and anti-tyrosinase (11.1±0.14% inhibition) activities compared to E. virgata extract. These results showed us that S. rotundifolium can be considered as a strong candidate for the management of epidermal hyperpigmentation and skin elasticity and deserves further study.
VIRTUAL BROKERS AND NATIONAL BOUNDARIES: TRANSNATIONAL ONLINE NETWORKS IN EUROPEAN ANTI-GENDER MOVEMENTS
Authors: Tronina Dominika
Published: December 2024

Digital technologies seem to have become a catalyst for the transnational spread of anti-gender movements, facilitating crossborder exchanges. This study examines the extent of crossborder communication as a form of transnational online networking on Twitter between 148 anti-gender movement organizations across five European countries (Croatia, Germany, France, Italy, and Poland) over ten years. Drawing on social movement theory and social network analysis, two communication networks consisting of follow-relations and interactions (retweets, replies, and mentions) are scrutinized to detect patterns and actors’ roles. The findings are mixed: online networking predominantly remains within national boundaries, with transnational contacts occurring only sporadically. However, a few brokers periodically bridge between domestic communities, sustaining the transnational character of the online network and crossborder information flow. The findings emphasize the pivotal function of specific actors in transnational online networking for anti-gender movements, with broader implications for social movements’ (online) transnationalization.
