Abstract— Problem-Based Learning (PBL) is increasingly recognized as an effective educational approach in engineering education, helping improve critical thinking and practical skills. In the context of the Antennas and Wave Propagation course for third-year Electronics and Communication Engineering (ECE) students, traditional teaching methods often fall short in engaging students and addressing all program outcomes (POs). This study involved implementing PBL in the Antennas and Wave Propagation course, where students were divided into teams and given a problem statement related to the course. Each team was tasked with developing a solution and creating a prototype. The implementation included several steps: defining the problem, brainstorming, research, solution design, prototype development, and final presentation. Data was collected through predefined rubrics assessing various criteria, such as problem understanding, solution quality, teamwork, and presentation skills. The rubrics were designed to map each activity to specific POs. The collected data was analyzed to compare the target and attained values of each PO to evaluate the effectiveness of PBL. The preliminary results indicate a positive impact of PBL on both student engagement and academic performance. Students demonstrated improved understanding and application of theoretical concepts, as evidenced by the quality of their prototypes and presentations. The analysis shows that the academic performance of the students is improved and attained values for most POs met or exceeded the target values, particularly in areas like problem-solving (PO2), Engineering design (PO3), Conduct Investigations (PO4), Modern tool usage (PO5), Teamwork (PO 9) and Project Management (PO11). Student feedback was overwhelmingly positive, highlighting enhanced learning experiences and increased motivation. This study explores the implementation of PBL to improve academic performance and ensure comprehensive coverage of POs.

Abstract - The DIGIT framework emphasizes spanning the gap between digital forensics theory and real-world challenges through PBL assessment and teaching methods. To develop the practical skills, this method uses interactive exercises like simulated cybercrime investigations and data recovery assignments. Summative evaluations, such as investigative reports and practical tests, guarantee thorough evaluation, while formative assessments, such as peer reviews and reflective journals, offer ongoing feedback. Students were organized into 18 groups, focusing on activity recognition in various domains such as data acquisition, evidence analyser, and reporting and presentation for PBL. With the help of this approach, students can confidently and competently handle challenging forensic situations. To establish a dynamic and engaging learning environment that reflects real-world problem-solving, evaluation and pedagogies are used in problem-based learning (PBL). With the goal of measuring both the process and results of student learning, assessments guarantee a thorough assessment of abilities and knowledge. In order to help students connect with the material on a deep level, pedagogies are created to encourage teamwork, creativity, and critical thinking. The course resulted in six live solutions, with two projects submitted for patents and six converted into research publications. Qualitative feedback indicated high levels of student satisfaction, with 88% reporting increased engagement and 89% feeling better prepared for realworld applications. Future research should investigate the scalability of this approach across various engineering disciplines and evaluate its long-term impact on students' career.

Published: January 2025

Abstract—Teaching programming to mechanical engineering students, often seen as a computer science endeavor, requires a thoughtful approach to highlight its relevance in their field. The mechanical engineering teacher can bridge this gap by demonstrating how programming solves complex engineering problems. Using real-world examples such as simulating mechanical systems or automating data analysis, illustrates the practical benefits of programming skills. To engage students, the teacher implemented Problem-Based Learning (PBL) activities tailored to mechanical engineering contexts. Activities like “Trace it Out,” where students identify code errors, and “Jumble the Code,” which involves ordering or debugging code pieces, help students connect programming concepts to engineering projects. Solutions to real-world problems are presented as poster presentations, making learning interactive and hands-on. Community problems and solutions were documented and assessed using designed rubrics, reinforcing programming knowledge and developing problem-solving skills. Regular feedback and project-based assessments, rather than traditional exams, better measure students’ understanding and ability to apply programming skills to engineering problems. This comprehensive approach—linking programming with mechanical engineering applications, mentoring, active learning, and continuous feedback—transforms students’ perspectives, helping them realize the invaluable role of programming in their professional development as mechanical engineers. Providing access to online resources and encouraging participation in coding communities further enhances their learning experience.

The article presents the developed methodology for specific energy consumption by the rolling stock of urban rail transport taking into account the possibility of energy return to the contact network or on-board energy storages. Meth-ods of analytical research and methods of electric traction theory are used. Dependences of specific energy consump-tion by a tram car taking into account its return to the contact network or on-board energy storages during electric brak-ing on starting acceleration at different efficiency of traction drive, as well as dependences of current consumed from the contact network on starting acceleration at different efficiency of traction drive are obtained. It is shown that the reduction of energy consumption for traction needs of urban electric rail transport can be achieved using electric brak-ing with the return of energy to the network or storing it in on-board energy storages. Increasing the starting acceleration is most effective for rolling stock with low efficiency of traction electric drive. For the rolling stock with high efficiency of traction drive, the increase of starting acceleration can give insignificant growth of specific energy consumption.
Primary Genetic Divergence in a System of Limited Population Coupled By Migration in a Ring Habitat
Authors: Kulakov Matvey , Frisman Efim Ya.
Published: January 2025

The paper is devoted to the study of conditions and mechanisms leading to genetic divergence in a system of panmictic populations coupled by migration. We propose a discrete-time model of the dynamics of abundance and genotype frequencies in a system consisting of such populations that inhabit a homogeneous ring-shaped area. The model describes natural selection acting on a single locus that is the same in all populations, as well as density-dependent factors described by the Ricker stock-recruitment model. The model consists of two layers of coupled maps (ensembles). The first layer describes the dynamics of population size for coupled subpopulations, with growth rates depending on the frequency of genotypes in each local site. The second layer describes changes in genotype frequencies, assuming that migratory gene flow depends on the ratio of abundances between the coupled populations. In this case, the gene flow into a subpopulation is stronger if the subpopulation from which migrants originate is more numerous (or if the receiving subpopulation is less numerous). We demonstrate that, with disruptive (diversifying) selection directed against heterozygotes, primary genetic divergence occurs depending on the initial conditions and persists indefinitely, resulting in a heterogeneous spatial distribution of individuals within the population range. It is shown that groups of monomorphic populations (clusters), where homozygotes predominate, are formed in the spatial distribution. It is shown that adjacent groups of monomorphic populations in which homozygotes predominant and form clusters in spatial distribution. Between these clusters with opposite genetic forms (alleles), there are small polymorphic groups whose presence is maintained by migration from neighboring sites and by hybridization. With constant migration, such groups persist for long periods of time. When individuals wander randomly, they form waves with a long period. We show that genetic divergence is accompanied by emerging significant differences in abundance and patterns of dynamics in different parts of the range (synchronous clusters).

Background: The use of antimicrobial agents in livestock production is inevitable and helpful in majority of their applications. However, their indiscriminate frequency of use has resulted in the deposition of antimicrobial residues in animal products and when that exceeds the maximum residue limits (MRLs) beyond permissible daily consumption put human health at risk. The present study aimed to detect Oxytetracycline and Tetracycline residues in the most popular meat (pork) marketed in and around Guwahati City (Kamrup Metropolitan) and its adjoining areas. Methods: The preliminary screening of the antimicrobial residues in 261 pork samples was carried out by microbial inhibition assay using endospores of Bacillus subtilis MTCC 441 as test organism. A total of 80 pork samples were further screened by Ultra-Fast Liquid Chromatography system-UV/Vis (Model: Shimadzu Prominence LC-20AD, Detector- SPD-20A-UV/Vis; RP C18 Column: BDS Premium, 250 mm x 4.6 mm, 5 mm) to detect Oxytetracycline and Tetracycline residues. Result: The preliminary screening revealed that none of the samples were positive for antimicrobial residues except 3 (three) which were doubtful to have traces of antimicrobial residues. On further screening, Oxytetracycline residues were detected in 2.5% of the samples, while none of the samples detected Tetracycline residue. The concentrations of the residues were 0.471 mg/g and 0.610 mg/g, respectively, which is well above the MRL value recommended by Codex Alimentarius. However, considering the detection of 2.5% Oxytetracycline residues and the absence of Tetracycline residue, it can be concluded that these antimicrobial compounds are not frequently misused in pig husbandry practices in these areas under study.

Objective: Hypertension presents a significant public health challenge in India, particularly among medical professionals who are notably vulnerable to this condition. Assessing their awareness about hypertension and lifestyle measures is crucial for effective intervention.
Methods: This cross-sectional study was conducted at SMS Medical College, Jaipur, involving 220 medical professionals aged 23 to 60 years, including 145 males and 75 females. The study aimed to estimate the prevalence of hypertension, assess knowledge regarding the condition, and gauge awareness of lifestyle interventions to curb it.
Results: Among the participants, 45.4% were normotensive, 43.2% had Stage I hypertension, and 11.3% had Stage II hypertension. The prevalence of hypertension was notably higher among those with higher body mass indices (BMI): 70% in the obese category, 56% in the overweight category, and 41.8% in the normal BMI group. Regarding awareness, 85% of the participants had good knowledge about hypertension, and 78% were aware of lifestyle measures to manage it. However, only 60% reported implementing these measures in their daily lives.
Conclusion: The study uncovered a high prevalence of hypertension among medical professionals. While awareness about hypertension and lifestyle measures is relatively high, actual implementation is suboptimal. Addressing BMI and promoting the adoption of lifestyle modifications could help mitigate the impact of hypertension within this group.

Objective: Caudal epidural block is widely used in pediatric surgeries for analgesia below the umbilicus. Traditional assessment methods like loss of anal sphincter tone are subjective and may not provide reliable feedback. The perfusion index (PI), measured non-invasively via the Masimo Radical-7 Pulse CO-Oximeter, may offer an objective alternative to predict block success.
Methods: In this prospective observational study, 50 pediatric patient’s aged 1 to 10 y undergoing elective lower abdominal surgeries received caudal epidural blocks under general anesthesia. Baseline PI values were recorded using the Masimo Radical-7 Pulse CO-Oximeter with the probe attached to the big toe. Measurements were taken at 1-minute intervals for 10 min post-block. Anal sphincter tone was assessed concurrently using a three-point qualitative scale by a blinded anesthesiologist. The primary outcome was the change in PI compared to baseline and its correlation with block success.
Results: Significant increases in PI values were observed in patients with successful caudal blocks. An increase in PI of more than 50% from baseline was associated with a 95% success rate of the block. The perfusion index showed a higher predictive value for block success (AUC = 0.88) compared to anal sphincter tone assessment (AUC = 0.72). The correlation between increased PI and successful block indicates that PI is a reliable indicator of caudal block efficacy.
Conclusion: The pulse oximeter perfusion index, measured using the Masimo Radical-7 monitor, is a more effective and objective tool than anal sphincter tone assessment in predicting successful caudal blocks in pediatric patients. Incorporating PI monitoring into perioperative care can provide immediate and reliable feedback, potentially improving anesthesia outcomes in children.
The Philosophical Underpinnings of Trump's Foreign Policy: Analyzing Key Influences and Implications

Published: January 2025

Donald Trump, the forty fifth President of the United States, has attracted and continues drawing sharp criticism regarding his foreign policy. Apart from being described in some circles as a nationalist, there is no denying that the President holds an extraordinary set of beliefs that are completely different from the rest of the world and dedicates himself to achieving them regardless of any type of backlash. ‘America First’, Mr Trump’s campaign slogan, sends messages which offer a glimpse to the intertwining principles of his policies and strong anti-globalist sentiment of the American people which results in a revolutionary view of a world order that focuses on restraint and traditionalism. In this scientific commentary, we will discuss the basic philosophical formatives that are guiding Trump's foreign policy and explaining how this world's perceptions not only impact the President's decisions, but also the international relations as a whole. Furthermore, we explore what this means for the wider understanding of politics where ideology and practice grow in opposite directions. We trust this will provide useful insights into what to expect out of US diplomatic relations in the subsequent years after the end of Mr. Trump’s presidency.

This study aims to describe the influence of the Concept Attainment learning model on the ability of eighth-grade students of SRO Matiti Middle School, Doloksanggul, to write persuasive texts. The research method used is an experimental design with a sample of 31 students participating as both the control and experimental groups (with a pre-test and post-test conducted). Data collection tools consist of written tests where students are assigned to create persuasive texts, assessed based on specific criteria. The hypothesis test results indicate that when compared with the t-table at a significance level of 5%, with degrees of freedom (df) = N-1 = 30, a t-value of 2.04 is obtained. Based on the calculated t-value (top) compared to the t-table value (t), it is found that to = 6.83, which is greater than the t-table (2.04). Consequently, we reject the null hypothesis (Ho) and accept the alternative hypothesis (Ha). This demonstrates that the Concept Attainment learning model significantly increases students' ability to write persuasively. In conclusion, implementing the Concept Attainment learning model substantially affects the ability of eighth-grade students of SRO Matiti Middle School to write persuasive texts.
