Authors: Audax Auxillius M , Karugaba Sosthenes Mulokozi , Kiiza Respicius Clemence
Published: January 2025

Power transformers are critical assets in TANESCO's grid substations, playing a vital role in ensuring a reliable and uninterrupted power supply. However, the growing challenges of ageing infrastructure, increasing energy demand, and reactive maintenance practices often lead to unplanned outages, higher operational costs, and reduced transformer availability. This dissertation focuses on the Development of a Maintenance Management System for Real-Time Monitoring of Power Transformers at TANESCO grid substations, with the goal of improving availability performance. The study explores the design and implementation of a Real-Time Monitoring Management System (RTMMS), leveraging advanced sensors, data analytics, and predictive maintenance techniques. The RTMMS continuously monitors critical parameters such as temperature, oil levels, dissolved gases, and load conditions, providing real-time insights into transformer health. By integrating predictive analytics, the system identifies potential faults early, enabling timely interventions and reducing downtime. Additionally, it supports data-driven maintenance planning, enhances operational reliability, and extends transformer lifespan. The proposed system addresses challenges such as high initial costs, data management complexity, and resistance to technological change through phased deployment, secure cloud solutions, and comprehensive training programs. The expected benefits include improved transformer availability, cost efficiency, enhanced grid sustainability, and a shift from reactive to proactive maintenance practices. This research underscores the transformative potential of real-time monitoring systems in modernizing maintenance management and aligns TANESCO with global best practices in energy sector innovation and operational excellence.

Published: January 2025

School dropout is among the phenomena challenging youth to achieve education and related skills to make them competitive in today’s global economy. This study explored the influence of socioeconomic factors and the dropping out of secondary school students; the extent of school dropout; and established the strategies for overcoming the school dropout syndrome at Nanyamba Town Council. The study utilized a qualitative approach using a study sample which included five headmasters, five class teachers, five class monitors, one ward educational officer, one quality assurance officer and one headquarters officer. A semi-structured interview was used for data collection. Findings disclosed that socioeconomic factors lead to students dropping out of school due to a lack of awareness of the importance of education and illiteracy in families. Parents’ low income and cultural aspects such as early marriage and early pregnancy. Divorce, lack of family planning, negative attitudes towards education especially for girls and parents' deaths were also found to be the problems leading to school dropout. Among the recommendations given are: the provision of scholastic materials, the provision of lunch by schools, mass mobilization and the need to sensitize the community on education to make them aware of the importance of secondary education
The Way Forward for Secondary School Students: The Role of Self-Determination Theory and Intrinsic Motivation
Authors: Yengkopiong Jada Pasquale
Published: January 2025

This study aimed to use self-determination theory to explore if teachers have ignited or thwarted students’ intrinsic motivation in secondary schools, and therefore, become or not become autonomous in their own learning. According to the theory, human motivation requires consideration of the innate psychological needs of individuals. These needs include autonomy, competence, and relatedness. The study was carried out by reviewing the literature on self-determination theory. The words used to retrieve the articles from the databases included self-determination theory, human motivation, intrinsic motivation, extrinsic motivation, autonomy, competence, and relatedness. It is reported that when students are intrinsically motivated, they become engaged in their own learning, and they can participate fully in the required activities. Under the right classroom conditions, the students are also autonomously motivated—that is, they are engaged in their academic work with authenticity and vitality. It is identified that when students understand the worth and purpose of the activities that are given to them to perform, they feel ownership, and autonomously carry out the activities. The autonomy-supportive environment is conducive to the students’ engagement in an integrative emotional regulation, and therefore, this conducive environment enhances students’ well-being, reducing emotional dysregulation, and fostering high-quality interpersonal relationships. So, teachers are discouraged from being authoritarian in their classrooms but encouraged to provide conducive learning environments for students to intrinsically engage in their education so that they can flourish

Authors: Rossi Septina
Published: January 2025

Anemia merupakan salah satu masalah kesehatan yang dapat menyebabkan penderitanya mengalami kelelahan, yang pada akhirnya berdampak pada penurunan kreativitas dan produktivitas. Selain itu, anemia juga meningkatkan risiko terjadinya penyakit di masa dewasa serta melahirkan generasi dengan masalah gizi. Prevalensi anemia di Indonesia tergolong cukup tinggi. Berdasarkan data Riskesdas 2018, prevalensi anemia pada remaja mencapai 32%, yang berarti 3-4 dari 10 remaja mengalami anemia. Hal ini dapat disebabkan oleh asupan gizi yang kurang optimal serta minimnya aktivitas fisik (Kemenkes RI, 2022). Kurangnya pengetahuan dan pendidikan kesehatan terkait pola hidup sehat pada bayi dan balita juga menjadi faktor penyebab. Dalam hal ini, penulis melaksanakan kegiatan pengabdian kepada masyarakat melalui pemberian edukasi kesehatan remaja untuk mencegah stunting serta melakukan skrining anemia pada remaja putri. Kegiatan tersebut diselenggarakan pada Selasa, 24 September 2024 di SMPN 3 Cisaga. Hasilnya menunjukkan bahwa 80% remaja telah memahami pentingnya kesehatan reproduksi dan konsumsi tablet tambah darah dalam upaya pencegahan stunting. Pemahaman tersebut tercermin dari keaktifan remaja putri dalam berdiskusi dan memecahkan masalah setelah mengikuti sesi edukasi.
The Contribution of R&D İnvestments to Technological Learning Capability: Evidence from Manufacturing İndustry Sectors of the Turkish Economy
Authors: Koç Ayhan , Yamak Nebi̇ye
Published: January 2025

Learning-by-searching is the process of experience in the emergence of new high-value-added products with the new knowledge and skills that an enterprise achieves through the network system it establishes with its own R&D unit, other enterprises, universities, and other information sources. The most important factor that contributes to learning-by-searching is undoubtedly the investments made in research and development in economic sectors. A review of the literature on the subject reveals that R&D expenditures are only used as the second independent variable in linear learning curve models. For this reason, in the existing applied studies, only a fixed representative learning rate, which is the average of the learning rates in the period in question, is determined. In this study, a two-factor dynamic learning curve model is used to measure the cost-reducing effect of R&D expenditures. Thus, in addition to learning-by-doing ratios, the evolution of learning-by-searching ratios over time is also taken into account. The findings of the study support the view in the literature that the learning-by-doing rates in the one-factor dynamic learning model are biased. In addition, in the two-factor dynamic learning curve model, it was also found that in periods when learning-by-doing loses its effect, learning-by-searching increases its effect.

This study aims to answer the research problem: how is the Effectiveness of the Implementation of Regional Regulation of Sambas Regency Number 4 of 2004 Concerning the Prohibition of Gambling in the Region? What is the Position of Regional Regulation No. 4 of 2004 in the Hierarchy of legislation. The research method is qualitative, with the type of field research and using an empirical legal approach. The results reveal that Sambas Regional Regulation No. 4 of 2004 is not running effectively and cannot be applied to ensnare criminal acts of gambling in the region. Currently, the application of criminal acts of gambling in Sambas Regency applies Article 301 of the Criminal Code. While the position of Regional Regulation No. 4 of 2004 in the hierarchy of legislation is below the Law. The consequence of this is that the Regional Regulation in question is contrary to the Criminal Code as a Law in terms of the content of Gambling and has an impact on the implementation of the Regional Regulation which in reality, the Regional Regulation has never been used to ensnare Gamblers, so the Regional Regulation should be null and void by law. So to create the principle of legal certainty, Regional Regulation No. 4 of 2004 must be revoked by using Regional Regulations as well.

REFUGEE PARTICIPATION IN DECISION-MAKING: ALIGNING LIVELIHOOD NEEDS WITH HUMANITARIAN SUPPORT PACKAGES
Authors: NADEGE SAMA LEKUNGHA
Published: January 2025

This article explores the nexus between refugee participation in decision-making and long-term solutions to their livelihood issues, arguing that humanitarian support programs are not sustainable because they do not align with the needs and interests of their beneficiaries. This argument is contested by sampled refugee opinions collected in two of Cameroon's largest refugee camps, which show that even though refugees are included in key decision-making processes, there is an incongruous unalignment between humanitarian support packages and the needs and interests of refugees. Additionally, several refugee humanitarian assistance initiatives have failed because of this unalignment. The paper also aims to demonstrate that the humanitarian action plan's failure to include beneficiary needs and interests in their action plans suggests that the sustainability of refugee development and reducing dependence on humanitarian support packages are not often the primordial objective of donor assistance.

Authors: BANO Dr. NARGISH , MOHAMMAD Dr. ARIF , BANO Dr. SHAHNAZ
Published: January 2025

Rising awareness of mental health in India has led to the formation of policy initiatives aimed at promoting mental well-being. These policies include instructions for teachers to prevent mental distress and promote mental health. Teachers’ perception, awareness, and preparedness to tackle mental health issues among students are crucial. Teachers can play a key role in improving mental health by identifying early symptoms of distress and promoting sound mental health among students. The study aimed to determine the current level of implementation of the RTE Act and the Mental Health Care Bill, assess the level of mental health awareness among teachers, and evaluate school counseling competencies related to mental health issues. The study is quantitative in nature, with data collected from twenty randomly selected schools through a questionnaire. The results showed a gap between policy creation and its successful implementation. Awareness, reach, and quality of services are uneven, particularly in the field of school education. The study reveals that the reality falls short of expectations, and there are numerous ethical initiatives in policies and practices that require strong campaigns to support grassroots actions aimed at improving the condition of school children suffering from mental health issues in India. The authors recommend identifying core areas within education and health policies, emphasizing the need for counselors in schools.

MULTIPLE INTELLIGENCE AND ITS IMPACT ON THE CAMEROONIAN LANGUAGE CLASSROOM
Authors: TABE NICOLINE AGBOR
Published: January 2025

The Educational systems imposed by colonization in Cameroon and Africa at large have been cognitively based, relying on memorization or the learners’ capacity to use the brain to process, store and retrieve what the teacher gives them in class during evaluations and intelligence is measured based on that. This situation has made learners whose learning style do not corroborate with such category to go unnoticed, unrepresented, underexploited, excluded during the teaching/learning process and evaluated as slow learners. This is a problem and inaccurate to the Cameroonian language classroom in particular and educational system in general. This paper therefore explores the perception and use of Multiple Intelligence by language teachers in GBHS Ekounou (Yaounde) and GBHS Bayelle-Nkwen (Bamenda) and its role in achieving a more inclusive teaching and greater learning outcomes. A mix survey (quantitative and qualitative) design was adopted for this paper. Through Gardner’s (1983) theory of multiple intelligence and questionnaires administered to key actors in the language classroom, data were designed, collected and analysed. Finding revealed that language teachers have a low perception of the use of multiple intelligences and thus, rarely apply it during their teaching thereby excluding learners from the teaching/learning process. Further findings indicate teachers’ low learners’ achievement as differentiation is rarely practiced during the teaching learning process.

We present the star formation rate–stellar mass (SFR–M
*) relation for galaxies in the Cosmic Evolution Early Release Science survey at 4.5 ≤ z ≤ 12. We model the JWST and Hubble Space Telescope rest-UV and rest-optical photometry of galaxies with flexible star formation histories (SFHs) using BAGPIPES. We consider SFRs averaged from the SFHs over 10 Myr (SFR10) and 100 Myr (SFR100), where the photometry probes SFRs on these timescales, effectively tracing nebular emission lines in the rest-optical (on  ~10 Myr timescales) and the UV/optical continuum (on  ~100 Myr timescales). We measure the slope, normalization and intrinsic scatter of the SFR–M

These results can be explained if galaxies at higher redshift experience an increase in star formation variability and form primarily in short, active periods, followed by a lull in star formation (i.e., “napping” phases). We see a significant trend in the ratio R
SFR = SFR10/SFR100 in which, on average, R
SFR decreases with increasing stellar mass and increasing redshift. This yields a star formation “duty cycle” of ~40% for galaxies with

The precise characterization and mitigation of systematic effects is one of the biggest roadblocks impeding the detection of the fluctuations of cosmological 21 cm signals. Missing data in radio cosmological experiments, often due to radio frequency interference (RFI), pose a particular challenge to power spectrum analysis as this could lead to the ringing of bright foreground modes in the Fourier space, heavily contaminating the cosmological signals. Here we show that the problem of missing data becomes even more arduous in the presence of systematic effects. Using a realistic numerical simulation, we demonstrate that partially flagged data combined with systematic effects can introduce significant foreground ringing. We show that such an effect can be mitigated through inpainting the missing data. We present a rigorous statistical framework that incorporates the process of inpainting missing data into a quadratic estimator of the 21 cm power spectrum. Under this framework, the uncertainties associated with our inpainting method and its impact on power spectrum statistics can be understood. These results are applied to the latest Phase II observations taken by the Hydrogen Epoch of Reionization Array, forming a crucial component in power spectrum analyses as we move toward detecting 21 cm signals in the ever more noisy RFI environment.

We present uniform modeling of eight kilonovae, five following short gamma-ray bursts (GRBs; including GRB 170817A) and three following long GRBs. We model their broadband afterglows to determine the relative contributions of afterglow and kilonova emission. We fit the kilonovae using a three-component model in MOSFiT, and report population median ejecta masses for the total, blue (κ
B = 0.5 cm2 g−1), purple (κ
P = 3 cm2 g−1), and red (κ
R = 10 cm2 g−1) components. The kilonova of GW170817 is near the sample median in most derived properties. We investigate trends between the ejecta masses and the isotropic-equivalent and beaming-corrected γ-ray energies (E

γ,iso, E

γ
), as well as rest-frame durations (T
90,rest). We find long GRB kilonovae have higher median red ejecta masses (M
ej,R ≳ 0.05 M
⊙) compared to on-axis short GRB kilonovae (M
ej,R ≲ 0.02 M
⊙). We also observe a weak scaling between the total and red ejecta masses with E

γ,iso and E

γ
, though a larger sample is needed to establish a significant correlation. These findings imply a connection between merger-driven long GRBs and larger tidal dynamical ejecta masses, which may indicate that their progenitors are asymmetric compact object binaries. We produce representative kilonova light curves, and find that the planned depths and cadences of the Rubin and Roman Observatory surveys will be sufficient for order-of-magnitude constraints on M
ej,B (and, for Roman, M
ej,P and M
ej,R) of future kilonovae at z ≲ 0.1.

In this work, we study the circumstellar material (CSM) around massive stars, and the mass-loss rates depositing this CSM, using a large sample of radio observations of 325 core-collapse supernovae (CCSNe; only ~22% of them being detected). This sample comprises both archival data and our new observations of 99 CCSNe conducted with the AMI-LA radio array in a systematic approach devised to constrain the mass loss at different stages of stellar evolution. In the supernova (SN)–CSM interaction model, observing the peak of the radio emission of an SN provides the CSM density at a given radius (and therefore the mass-loss rate that deposited this CSM). On the other hand, limits on the radio emission, and/or on the peak of the radio emission provide a region in the CSM phase space that can be ruled out. Our analysis shows a discrepancy between the values of mass-loss rates derived from radio-detected and radio-nondetected SNe. Furthermore, we rule out mass-loss rates in the range of 2 × 10−6–10−4
M
⊙ yr−1 for different epochs during the last 1000 yr before the explosion (assuming wind velocity of 10 km s−1) for the progenitors of ~80% of the Type II supernovae (SNe II) in our sample. In addition, we rule out the ranges of mass-loss rates suggested for red supergiants for ~50% of the progenitors of SNe II in our sample. We emphasize here that these results take a step forward in constraining mass loss in winds from a statistical point of view.
Study on the Shallow Decay Segment of Gamma-Ray Burst X-Ray Afterglow

The X-ray afterglow of a certain fraction of gamma-ray bursts (GRBs) comprises a phase of shallow decay. However, the origin of the shallow decay segment is still a mystery. In this paper, we select 103 GRBs that exhibit a shallow decay segment, based on Swift/XRT data prior to 2023 June. We apply the fallback accretion energy external dissipation model to the shallow decay segment in our sample, and find the model can interpret the shallow decay segment within a reasonable range of parameter space. The fallback rate of the progenitor envelope materials onto the accretion disk can reach a peak of 10−7–0.1 M
⊙ s−1 within a time frame of 10–105 s, which is consistent with the typical density profile and spin profile of the progenitor of a GRB. During the fallback process of progenitor envelope materials, progenitor stars of most GRBs have the highest fallback rate at a radius ~1010 cm, which is consistent with the typical radius of a Wolf–Rayet star. The production of shallow decay segments of most GRBs in our sample requires injecting Blandford–Znajek (BZ) energy equal to 10–100 times the kinetic energy of the initial GRB blast wave into the blast wave. However, the shallow decay segment of a few GRBs requires the injected energy to be comparable to the kinetic energy of the blast wave, which means that even if less energy is injected into a GRB blast wave, it is still possible to produce a shallow decay segment. In addition, the peak time of the fallback rate of the progenitor envelope materials is close to the time when BZ energy is injected into the blast wave, which means that the fallback accretion is more active in the initial phase. In summary, our research results provide further support to an external origin for the shallow decay segment in GRBs.

We present the results of our multiwavelength (X-ray to radio) follow-up campaign of the Einstein Probe transient EP240408a. The initial 10 s trigger displayed bright soft X-ray (0.5–4 keV) radiation with peak luminosity L
X ≳ 1049 (1050) erg s−1 for an assumed redshift z ≳ 0.5 (2.0). The Neil Gehrels Swift Observatory and Neutron star Interior Composition ExploreR discovered a fading X-ray counterpart lasting for ∼5 days (observer frame), which showed a long-lived (∼4 days) plateau-like emission (t
−0.5) before a sharp power-law decline (t
−7). The plateau emission was in excess of L
X ≳ 1046 (1047) erg s−1 at z ≳ 0.5 (2.0). Deep optical and radio observations resulted in nondetections of the transient. Our observations with Gemini South revealed a faint potential host galaxy (r  ≈  24 AB mag) near the edge of the X-ray localization. The faint candidate host, and lack of other potential hosts (r ≳ 26 AB mag; J ≳ 23 AB mag), imply a higher redshift origin (z ≳ 0.5), which produces extreme X-ray properties that are inconsistent with many known extragalactic transient classes. In particular, the lack of a bright gamma-ray counterpart, with the isotropic-equivalent energy (10–10,000 keV) constrained by GECam and Konus-Wind to E

γ,iso  ≲  4 × 1050 (6 × 1051) erg at z  ≈  0.5 (2.0), conflicts with known gamma-ray bursts of similar X-ray luminosities. We therefore favor a jetted tidal disruption event as the progenitor of EP240408a at z ≳ 1.0, possibly caused by the disruption of a white dwarf by an intermediate-mass black hole. The alternative is that EP240408a may represent a new, previously unknown class of transient.

Saprobic hyphomycetes with high density and species diversity were observed on plant debris. During our mycological surveys in southern China, numerous strains were isolated from dead branches of unidentified plants in the forest of Jiangxi and Fujian provinces, China. Phylogenetic analyses of ITS, LSU, RPB2, and TEF1 sequence data using maximum-likelihood (ML) and Bayesian inference (BI) methods revealed the systematic placement of several Sporidesmium-like species within Distoseptispora. Based on morphological characteristics and molecular evidence, four new species of Distoseptispora, namely D. fujianensis, D. ganzhouensis, D. nanpingensis and D. subtropica, are introduced, and two known species, D. clematidis and D. yunjushanensis, are reported. This study enhances our knowledge of the species diversity of Distoseptispora in southern China.
