Published: December 2024

The industry is crucial for the economic development of the country, but at the same time, it is one of the biggest influences on the environment. The Mitrovica region faces numerous environmental problems due to the mining-industrial processes applied in the facilities of the industrial complex "Trepça". As a result of these processes, industrial waste with a toxic composition is created, which is considered a potential polluter of soil, air, water, and vegetation in this area. The study aims to determine the concentration of heavy metals including Pb, As, Zn, Ni, Co, Cr, Cd, and Cu in soil samples. Also, the level of soil pollution with heavy metals was examined, using pollution indicators, such as contamination factor (CF), degree of contamination (Cd), modified degree of contamination (mCd), pollution load index (PLI), and geo-accumulation index (Igeo). To carry out this research, we selected 6 sampling sites in the period May - August 2024, which were characterized and evaluated as the most critical points. The concentration of heavy metals in soil samples was determined using inductively coupled plasma-optical emission spectrometry (ICP–OES Optima 2100 DV, Perkin-Elmer) by standard method US EPA 6010C. From the obtained results it was found that the level of heavy metals analyzed in this work, respectively the level of zinc (197.84 - 3456.14 mgkg-1), lead (204.75 - 3458.16 mgkg-1), and arsenic (30.76 – 634.56 mgkg-1) is relatively high and exceeds the allowed values ​​recommended by Kosovo and European Legislation.

Published: December 2024

Diets based on low glycaemic index (GI) breads are important for the sustainability and prevention and control of diabetes 2 mellitus. The aim is to apply the QFD methodology to the design of a new type of low postprandial response bread for the diabetic population. The postprandial response was evaluated, and the GI of boxed breads made from germinated lentils (two and five-day germination) was calculated. 47 requirements were identified for the design of the bread, of which those related to its characteristics and price stand out. The characteristics include that the bread should be nutritious, without chemicals, with low GI and low cost. Using the QFD method, it was suggested that bread made from sprouted lentils with chia could be an option.  The glycemic index of this type of bread was classified as low GI (40, 10), with the index decreasing as the days of germination of the sprouted lentils increased.

Published: December 2024

The ferromagnetic Fe65.5Cr4Mo4Ga4P12C5B5.5 bulk metallic glass rods of 1.8 mm
diameter were prepared prepared by the copper-mold casting technique.
As-quenched and successive furnace annealed samples were examined by thermal
analysis (DTA), X-ray diffraction (XRD), thermomagnetic, coercivity, and
hardness measurements. The wide supercooled liquid region DTx of 57 K and
reduced glass transition temperature Trg of 0.57 indicate enhanced glass
forming ability and high thermal stability against crystallization. After
the third annealing at 673 K the most intensive stress relief is followed by
an increase in the magnetic permeability of 23%, an increase in the Curie
temperature (to 558 K), and an improvement in coercivity of about 40%.
Coercivity abruptly increases after thermal treatment at 773 K, indicating
the presence of crystalline inclusions that hinder stress relief. The XRD
pattern of the rod annealed at 873 ? shows several intermetallic compounds
formed by crystallizing the amorphous phase, such as B48B2C2, and iron-based
compounds Fe2??4C and Fe3B. The rods were explored for the increase in
hardness which evolved due to stress relief and after transformation from
the amorphous into crystalline phase.

Published: December 2024

The renoprotective effects of sodium-glucose cotransporter-2 (SGLT2) inhibitors in both diabetic and nondiabetic nephropathy are widely recognized due to results from randomized controlled trials notably the DAPA-CKD and EMPA-KIDNEY trials. Research exploring the mechanisms of renoprotection indicates that SGLT2 inhibitors exert protective effects on podocytes by enhancing autophagy and stabilizing the structure of podocytes and basement membranes. Furthermore, reductions in lipotoxicity, oxidative stress, and inflammation have been confirmed with SGLT2 inhibitor treatment. Recent clinical studies have also begun to explore the effects of SGLT2 inhibitors on nondiabetic podocytopathies, such as focal segmental glomerulosclerosis. In this review, we summarize clinical and laboratory studies that focus on the podocyte-protective effects of SGLT2 inhibitors, exploring the potential for broader applications of this novel therapeutic agent in kidney disease.

Published: December 2024

The current issues related to land ownership rights revolve around the frequent complaints from the community about the authenticity of customary land release documents and some individuals within the indigenous community deliberately selling communal land that does not belong to them. Hence, it is necessary to analyze the role of the Indigenous Community Institution (ICI) in addressing land ownership issues. This research is qualitative in nature, with the research subjects being members of the ICI of Village and the indigenous community present in the village. The data collection methods used include observation, interviews, and documentation. After obtaining data through observation, interviews, and document collection, this data will go through a systematic series of analysis stages. These stages include data reduction, data presentation, and drawing conclusions based on information obtained from informants or sources related to the role of the Indigenous Community Institution (ICI) in supporting the issuance of land ownership certificates. The Indigenous Community Institution (ICI) of Village has three main roles, namely the Interpersonal Role, the Informational Role, and the Decision-Making Role. The ICI serves as a bridge between the indigenous community, the government, and the general public, with the aim of ensuring fair and pro-indigenous community policies. To enhance its effectiveness, communication and collaboration between the ICI, the government, and the community need to be strengthened. Additionally, there should be education and awareness-raising among the indigenous community regarding their customary land ownership rights.

Sustainable development within music education is essential, particularly in ensuring that popular music can continually and effectively serve educational systems. This research aims to 1) examine pop music chord progression, 2) develop a chord progression book specifically for teaching music students, and 3) evaluate the effectiveness of this educational tool in improving music composition skills. A mixed-methods approach, incorporating both qualitative and quantitative research, was used. Research tools included an interview guide, Ioc forms, a textbook, and a performance assessment form. Interviews were conducted with five experts in pop music composition, while a group of 14 undergraduate music students participated in the experimental study. These methods evaluated how teaching popular music chord composition enhances students’ practical composition abilities. The findings indicate that 1) chord composition in popular music primarily involves five aspects: melody, rhythm, chord structure, music form, and melody development techniques, with melody and chord as the foundational elements; 2) the chord progression textbook for popular music differs from traditional composition theory texts, combining theory and practical application with a focus on chord progression techniques; and 3) instruction in popular music chord composition significantly enhances students’ skills in melody creation, production, and listening, ultimately fostering practical music creation abilities. This study supports the sustainable integration of popular music in both music infrastructure construction and music education system development, offering insights into how such integration can drive long-term advancements in music education.

Published: December 2024

Growing urbanization in sub-Saharan Africa, with its attendant degradation of natural vegetation, is a real scourge. It takes the form of urban sprawl, with its corollary of native vegetation degradation. The aim of this study is to assess the impact of urban sprawl in Brazzaville and the related degradation of the vegetation covering on the urban site. The methodological approach was based on the collection of documentary and field data, as well as the analysis of Landsat satellite images from 2002, 2012 and 2022. The results show a regressive evolution of natural plant formations in favor of urbanization. The area of vegetation cover fell from 17,523 ha in 2002 to 8355.5 ha in 2022, representing a regression rate of 52.32% in 20 years. At the same time, the urban area has grown from 12,164 ha in 2002 to 29,892 ha in 2022, an increase of 145.74%. This deterioration in vegetation cover is reflected in water erosion, resulting in silting-up and flooding of homes and sanitation facilities.

Authors: Wu Xuandong , Lu Jianan , Cao Mingming , Qiu Hongbo
Published: December 2024

The oil-cooled back-wound high-speed permanent magnet generator (OBHPMG), is suitable for the aerospace field, gas turbines, and flywheel energy storage due to its high efficiency as well as high-power density. However, the high-power density operation of the generator inevitably results in a significant temperature rise, particularly when inter-turn short circuit faults (ISCFs) occur in the windings. In order to clarify the electromagnetic as well as thermal characteristics of the OBHPMG under the different ISCF degrees, it is of great significance to research the electromagnetic and temperature field variation characteristics of the generator at various inter-turn short circuit faults degrees. Firstly, the electromagnetic field of the 40 kW OBHPMG is investigated at normal operating in this paper, the rotor eddy current densities as well as stator core magnetic flux densities distribution is determined. Secondly, based on the model of the generator ISCF, the effects of the winding different ISCF degrees on the rotor eddy current densities and stator core magnetic flux densities are further explored in detail. The variation characteristics of the rotor current loss as well as stator core magnetic flux densities under the winding different ISCF degrees are revealed. Finally, the effect of the different ISCF degrees on the windings and permanent magnets temperature is analyzed in depth by combining the variation mechanism of the electromagnetic loss. The temperature variation characteristics of the OBHPMG with the different ISCF degrees are obtained, and the cooling effect of the OBHPMG under the ISCF is clarified. It provides a theoretical basis for clearly mastering the variations in the performance of the generator under the windings ISCF in this paper.

Published: December 2024

The virtual synchronous generator (VSG) and sinusoidal pulse width modulation (SPWM) are two prominent control strategies that have attracted particular interest recently. In this paper, we compare these two inverter control strategies in a 5MW wind power conversion chain. The studied conversion chain includes a wind turbine, a permanent magnet synchronous generator, the power converters, namely the uncontrolled rectifier, and a two-stage inverter connected to the grid via an LCL filter. Our study of the two control methods shows that both strategies reduce the total harmonic distortion (THD) while respecting the grid connection conditions. The simulation results manifest that the VSG strategy has a better THD reduction of 0.99 % which is improved compared to the SPWM with a THD of 1.33%.

Authors: Kim Gyumin , Kim Youngung , Choe Kue Hwan , Oh Sangjun , Heo Su Young , Kim Namsoo
Published: December 2024

OBJECTIVE

This study aimed to evaluate the prognosis of root canal treatment (RCT) in dogs with complicated crown-root fractures (CCRFs) of the maxillary fourth premolar (PM4), focusing on the impact of periodontal probing depth (PPD) and furcation involvement on treatment outcomes.

METHODS

The study analyzed 122 PM4 teeth affected by CCRF in dogs. The primary outcomes were the success rates of RCT, measured against PPD, and the degree of furcation involvement (stages F0, F1, and F2). The PPD was measured preoperatively to assess its correlation with treatment prognosis.

RESULTS

The analysis revealed that RCT outcomes were poor when PPD reached or exceeded 5.43 mm at the F0 stage of furcation involvement. Similarly, poor prognoses were associated with a PPD of 4.60 mm or more at the F1 stage and 3.76 mm or more at the F2 stage. These findings indicate a significant relationship between PPD, furcation involvement, and the success of RCT in CCRF-affected PM4 teeth.

CONCLUSIONS

Both PPD and furcation involvement are critical factors influencing the success rate of RCT in dogs with CCRF-affected PM4 teeth. When considering RCT for such cases, these parameters should be carefully evaluated to optimize treatment outcomes.

CLINICAL RELEVANCE

This study highlights the importance of assessing PPD and furcation involvement in the decision-making process for RCT in dogs with CCRF of the PM4 teeth, providing valuable insights for veterinary dental practitioners.
Few differences in rural and urban adoption of veterinary telehealth services
Authors: Neill Clinton L. , Morgan Kimberly L.
Published: December 2024

OBJECTIVE

To determine the current reasons why or why not veterinarians use certain telehealth services and the barriers to usage of these same services. Moreover, we aimed to understand how veterinarians differ in the use of such services across urban and rural areas.

METHODS

Usage and nonusage rates between rural and urban/suburban practitioners were computed and tested via paired t tests where appropriate. The most common reasons why various telehealth services were and were not adopted were also computed. Didactic comparison was used to compare reasons between rural and urban respondent subsamples.

RESULTS

The results showed that concerns around liability, suboptimal care, familiarity of the services, and staff willingness to use telehealth services were the primary concerns. Other reasons were also often cited. For those who adopted telehealth services, increasing efficiency was often the most cited reason.

CONCLUSIONS

There were some differences in reasons for adoption between rural and urban practices, but many of the reasons were largely the same. The differences can be attributed to general differences between rural and urban practices (ie, different types of animal populations). Concerns about care and staff willingness to adopt various telehealth services were predominate reasons.

CLINICAL RELEVANCE

Given the reasons documented in our findings for not using telehealth services, efforts to train and educate on how to use these services appropriately could help expand the use of these services. Doing so could expand veterinary care access to existing and new clients, improve cost management, and increase revenue for veterinary practitioners.

Authors: Kogan Lori R. , Rishniw Mark
Published: December 2024

OBJECTIVE

To gain an understanding of the perceptions and experiences of retired veterinarians.

METHODS

An invitation to participate in an electronic survey distributed via the Veterinary Information Network data collection portal was sent to veterinary members of the Veterinary Information Network who identified as retired. Data were collected between August 15, 2024, and September 14, 2024.

RESULTS

We received 512 responses from veterinarians who indicated they had retired. Participants rated a desire for more free time, having sufficient financial security, and a desire to maintain good health as the most important factors in their decision to retire. The most frequently endorsed negative aspects of retirement included concerns about clients and establishing a routine. The most frequently endorsed positive aspects included feeling more relaxed and being able to do more of what they enjoy. A higher percentage of females endorsed several positive aspects of retirement than males.

CONCLUSIONS

The results suggested that most retired veterinarians adjust well to retirement and reap the positive aspects of a retired lifestyle. A minority, however, struggle. To help ensure everyone is able to transition well and enjoy their retirement years, veterinary organizations should consider offering retirement-related guidance and resources, similar to those offered to new graduates entering the field.

CLINICAL RELEVANCE

In an era characterised by the rapid dissemination of information through digital platforms, the proliferation of fake news has emerged as a pressing global concern. Misinformation, deliberately fabricated or misleading content presented as factual news, poses significant threats to public discourse, trust, and decision-making processes. The research highlights the significance of fake news detection in the Arabic language, with a specific focus on the Algerian dialect. The Arabic language exhibits great diversity and complexity, making the detection of false information, all the more crucial. The rapid spread of fake news through social media platforms has a significant impact on individuals and society as a whole. To address this challenge, this paper presents TruthGuardian, an innovative solution that combines machine learning and deep learning techniques with voting system for the last decision. This solution enables fast and accurate identification of fake news in the Arabic language, with emphasis on the Algerian dialect. It provides reliable and effective results in countering misinformation.

Predicting age and gender through images is a common computer vision problem with many practical applications. However, this problem faces many difficulties because a person’s age can be affected by genetics, living environment, diet, health, gender, and other factors. Therefore, the accuracy of the prediction model may decrease due to the enormous diversity and variability in the data. In this study, we use three models, including Unet, MobileNets, and EfficientNets, to test the performance of predicting a person’s age and gender through their photos. In addition, we also adjust the learning rate parameter to find optimal performance. The best results for gender prediction are achieved by the Unet model with the highest accuracy of 97.22 %, and the MobileNets model gives age prediction results with MAE = 2.248, learning rate 0.001 for optimal performance in the models of our study.

Published: December 2024

During the latest decades, regional creativity has often been considThis study seeks to investigate the relationship between interest rates, liquidity, and leverage to non-financial companies in Indonesia who have issued bond securities between 2018 and 2023 with profitability as an intervening variable. Panel data regression analysis and path analysis are used in the study to explore the connections between the variables, both directly and indirectly. According to the results, bond ratings are heavily affected by interest rates, but liquidity does not appear to play a major role. Moreover, leverage appears to have a positive effect on bond ratings. Moreover, profitability is significantly influenced by interest rates, while leverage has a detrimental effect on profitability. The study suggests that there is a slight influence of profitability on the connection between interest rates and bond ratings, but not for liquidity or leverage. Interest rates are found to have a significant positive effect on bond ratings, whereas liquidity and leverage have minor direct impacts. These findings contribute to investors in making bond investment decisions, as well as for companies in optimizing their capital structure to improve bond ratings. This study suggests further development by expanding the coverage of other industry sectors and adding variables such as corporate governance and macroeconomic indicators to increase external and internal validity.
The Destruction and Reconstruction of Community: A Study of The Light Pirate from a Posthumanist Perspective
Authors: Kang Li , Wanyin Yang
Published: December 2024

In recent years, given the increasing occurrence of extreme weather events and the growing public awareness of climate issues, climate fiction has emerged as a popular genre, and Lily Brooks-Dalton’s novel The Light Pirate serves as a quintessential example of climate fiction. In the book, Dalton presents an imagined catastrophic scenario caused by floods and hurricanes. After the disintegration of various communities, the protagonist, Wanda, remains in her fragmented hometown and goes on to create a posthumanist community. Based on the theories of community and critical posthumanism, the evolution of communities during the climate crisis is interpreted from three perspectives: how various types of communities are destroyed by climate change, why residents in the face of a dilemma adopt different coping mechanisms, and what kind of posthumanist community is reconstructed after the climate crisis. All in all, by describing the fate of the community under the climate crisis, the novel warns people to protect the environment, reveals the complex relationship between man and nature, and suggests a possible way out when faced with the threat of climate change, that is, to live in harmony with other creatures.

This paper presents an advanced Low Noise Amplifier (LNA) tailored for high-precision navigation applications, designed using the 180nm technology node and implemented in Cadence Virtuoso. The LNA features a single-ended amplifier configuration with cascaded NMOS transistors to achieve superior isolation and input matching through source degeneration, optimizing gain and noise performance. At 1.2 GHz, the amplifier achieves a gain of 33 dB and a noise figure of 1.3 dB. It demonstrates a 1 dB compression point of –16 dBm and a third-order intercept point (IIP3) of –10 dBm, with a power consumption of 44 mW from a 1.8 V supply. Post-layout simulations reflect a noise figure of 2.9 dB and a gain of 19.5 dB, highlighting practical design considerations. The layout area is 0.51 mm², underscoring the compact yet highly efficient design.

Published: December 2024

This research presents a high-performance MIMO antenna for 5G and next-generation wireless communication. Operating in the millimeter wave (mmWave) band, the antenna offers frequency and radiation pattern reconfigurability. A compact-size antenna, with dimensions of 22.5×30×0.787 mm3, exhibited peak gains of 7.5 and 6.5 dBi at 28 and 38 GHz, respectively. The envelope correlation coefficient (ECC) was improved through proper spacing and adopting a simple decoupling technique, ensuring efficient MIMO operation. Based on the evaluated reflection coefficients, bandwidths of 2.3 and 12.9 GHz at 28 and 38 GHz, respectively have been accomplished. The mutual coupling between antenna elements was minimized achieving improved isolation of −37 and −40 dB at the desired frequency bands. This corresponds to an envelope correlation coefficient and diversity gain of 1.6×10−4 and 9.99, respectively. The antenna gain was enhanced by incorporating a metasurface designed to optimize gain and improve isolation. For a single-element antenna, the gain was enhanced to 7.9 and 7.3 dBi at frequencies of 28 GHz, and 38 GHz, respectively. The antenna design incorporates frequency and pattern reconfigurability through switching selected antenna ports and patches. The proposed design’s simplicity and antenna compactness make it practical for various mmWave communication systems.
Vertically heated natural convection loop model

Published: December 2024

We present a comprehensive analytical model for laminar flow in a vertically heated rectangular convection loop, with applications to oil cooling in transformer systems. Starting from an integral equation, we apply a quasi-one-dimensional approach to derive equations for both loop velocities and temperature distributions. In this model, we account for temperature-dependent dynamic viscosity and introduce cooling at the loop top and in the fin. The analytical predictions are rigorously validated against finite volume method (FVM) simulations across different geometries and heat flux conditions, demonstrating strong agreement within a 2% discrepancy range for most parameters. This model provides a viable analytical alternative to computationally intensive simulations, offering insights into natural convection dynamics within closed-loop configurations.
Battery-less grid-forming type converter in an isolated AC microgrid
Authors: Teran Raul , Perez Javier , Beristain Jose , Valle Obed
Published: December 2024

Typically, in electrical microgrids (MG), the grid-forming type converter (GFRTC) includes a battery pack at its DC bus; thus, the GFRTC is modelled as a voltage source. In contrast with papers reported in recent literature, where the GFRTC with a battery pack is seen as a voltage source, this work proposes a GFRTC which can be used without a battery pack; with this, the GFRTC operates as a smart load to form the voltage at the point of common coupling (PCC); this is possible, as long as the smart load is supported by a grid-following type converter (GFLTC). This battery-less GFRTC proposal ensures a suitable operation of the isolated MG under linear and nonlinear load conditions. Also, this work proposes a control strategy for both GFRTC and GFLTC with a photovoltaic array. The test results showed that the control proposal allows to form a correct PCC voltage, ensuring a suitable operation of the isolated MG; this while the battery pack is: connected, disconnected, and reconnected to the GFRTC DC bus. This GFRTC proposal is very attractive for isolated MGs where the GFRTC battery pack must be replaced or reconfigured because of new demand profiles, without interrupting the isolated MG operation.

Aim. The present paper aims to explore the challenges faced by employment agencies when recruiting Ukrainian refugee-background nurses (UKR-N) during the Ukrainian war refugee crisis in Poland, after the outbreak of war in February 2022.

Material and methods. Data were collected through semi-structured, in-depth interviews conducted in Poland with two representatives of one recruitment agency between May and July 2023. There were two female participants, one of Polish origin and one of Ukrainian origin. The data were analyzed using inductive thematic analysis. The ATLAS.ti 8 software was used for data management.

Results. Two themes were identifi ed: 1. Business-as-usual factors determining the eff ectiveness of international nurse recruitment and 2. Issues specifi c to the recruitment of Ukrainian refugee nurses. These two themes were further subdivided into six subthemes.

Conclusions. Recruitment agencies have an obligation to adopt a comprehensive approach to the recruitment of this group of applicants. In addition, the inappropriate recruitment of refugee-background nurses by recruitment agencies (RAs), which may lead to abuse and exploitation, violates fundamental human rights, and should be universally condemned and strongly discouraged.
