Abstract

The increasing environmental problem of fertilizer wastewater associated by high loads of pollutants, necessitates the microbial fuel cell innovative treatment technologies that not only mitigate pollution but also generate power. This research investigates the dual-purpose application of Microbial Fuel Cells (MFCs)for thecombined treatment and power generation from fertilizer wastewater, offering a sustainable solution that integrates wastewater remediation with renewable energy production. The study explores the design, optimization, and performance evaluation of single- and dual-chamber microbial fuel cell systems using urea fertilizer wastewater as substrates. Key parameters including chemical oxygen demand (COD) removal efficiency, dissolve Oxygen, % ammonia and %Urea reduction, Current and power density were monitored under varying operational conditions (e.g., electrode materials, pH, temperature, retention time). Advanced electrochemical and microbiological techniques were employed to characterize the anodic biofilms and understand the dynamics of the electroactive microbial communities driving the simultaneous biodegradation and electron transfer processes. Result demonstrate that microbial fuel cell can achieve treatment of fertilizer wastewater (COD > 80%, ammonia > 70%) while generating stable output outputs up to 0.66MA and voltage of 0.91V, depending on reactor configuration and substrate concentration. The experimental result shows that Ammonia fertilizer plant effluent is one of the best substrates for energy generation in mfc. The integration of bio electrochemical systems with fertilizer industry effluents not only enhances wastewater treatment efficiency but also contributes to decentralized. This thesis provides a comprehensive analysis of the feasibility, challenges, and scalability of MFC technology for agro-industrial applications, contributing to the global pursuit of circular economy models and sustainable wastewater-energy nexus solutions.

Abstract

The study examined the comparative effects of Reciprocal Peer Learning (RPL) and Traditional Teaching Approaches (TTA) on learners’ retentive ability in literary appreciation among senior secondary school students in Anambra State, Nigeria. The study employed a quasi-experimental pretest-posttest non-equivalent control group design involving 65 SSII students. The experimental group was taught literary appreciation using Reciprocal Peer Tutoring (RPT), while the control group used the conventional method. The Literature-in-English Achievement and Retention Test (LART) served as the instrument, validated and found reliable (r = 0.721). Data were analyzed using mean, standard deviation, and ANCOVA at a 0.05 significance level to determine differences in students’ achievement and retention in literary appreciation. The results showed that students taught literary appreciation using Reciprocal Peer Tutoring (RPT) achieved higher retention than those taught with the conventional method. The RPT group had a posttest mean of 68.83 (SD = 10.02) and a retention mean of 72.68 (SD = 10.72), while the conventional group had a posttest mean of 35.61 (SD = 9.72) and a retention mean of 36.98 (SD = 9.61). The retention mean gain of 3.85 for RPT exceeded 1.37 for the conventional method. ANCOVA results (F = 183.169, p = .000) indicated a significant difference favoring RPT. The result indicated that peer collaboration and active engagement promoted deeper comprehension and better memory retention of literary concepts. The study concluded that Reciprocal Peer Learning enhances learners’ retentive ability and should be integrated into Literature-in-English instruction to improve learning outcomes.

Abstract

Students’ poor achievement in Literature-in-English, particularly in the area of literary appreciation, has continued to be a major concern among educators and stakeholders in Nigeria. The conventional teacher-centered approach often limits students’ engagement, critical thinking, and interpretive skills, which are essential for understanding literary texts. To address this challenge, the study investigated the effect of Reciprocal Peer Tutoring (RPT) on students’ achievement in literary appreciation compared to the Conventional Teaching Method in public secondary schools in Anambra State. The study adopted a quasi-experimental pretest-posttest non-equivalent control group design to examine the effect of reciprocal peer tutoring (RPT) on students’ achievement and retention in Literature-in-English in Anambra State. Intact SSII classes were used, with 65 students randomly assigned to experimental and control groups. Data were collected using a validated and reliable Literature Achievement and Retention Test (LART). Trained teachers administered pretests, treatments, posttests, and retention tests over six weeks. ANCOVA was used to analyze data, controlling extraneous variables. The study ensured methodological rigor through standardized procedures, uniform lesson plans, and careful monitoring to achieve credible findings. The results showed that students taught literary appreciation using Reciprocal Peer Tutoring (RPT) had higher achievement scores than those taught with the conventional method. The RPT group (N=31) had a pretest mean of (41.24) and posttest mean of (68.83), with a mean gain of (27.59), while the conventional group (N=34) had a pretest mean of (32.70) and posttest mean of (35.61), with a mean gain of (2.91). ANCOVA results revealed a significant difference between the groups (F=211.397, P=0.00<0.05), leading to the rejection of the null hypothesis. Thus, RPT significantly enhanced students’ achievement in literary appreciation. It was concluded that Reciprocal Peer Tutoring significantly enhanced students’ achievement in literary appreciation. The study recommended that Literature-in-English teachers should adopt RPT to promote active learning, deeper comprehension, and improved performance among students.

Abstract

Quality control remains a fundamental driver of organizational performance, yet its success often depends on the extent of management support. In contemporary business environments, where customer satisfaction and competitiveness hinge on product and service quality, managerial involvement has become indispensable. This study investigated the role of management support in driving employees’ quality control practices. This study employed a survey research design, using questionnaires to gather data from a sample of 98 respondents, determined from a population of 130 using Yamane’s (1967) formula. The questionnaire method ensured the collection of reliable facts and figures for analyzing research questions and testing hypotheses. Data analysis involved simple percentage calculations to compare response trends and draw logical conclusions. Hypothesis testing was conducted using the Chi-square (χ²) statistical tool at a 5% significance level and 4 degrees of freedom. The decision rule specified rejecting the null hypothesis when χ² calculated exceeded the critical value, thereby accepting the alternative hypothesis. The results show strong agreement among respondents that management support influences employee commitment to quality control. A majority (74 respondents; 75.51%) strongly agreed, while only a small proportion disagreed (5.10%). Chi-square analysis further confirmed significance, with a calculated value (192.51) exceeding the table value (9.49), leading to acceptance of the alternative hypothesis that management support drives seriousness in quality control. Gender differences were evident: most males strongly agreed (68), while females showed more variation, with some selecting agree (13) or undecided (6). Association measures such as Phi (.857) and Cramer’s V (.857) confirmed strong relationships, though negative ordinal correlations highlighted divergent response patterns. Gender-based variations were also observed, with male respondents showing higher consensus compared to females. The study concludes that managerial presence, incentives, and commitment to quality strongly shape employees’ adherence to quality standards, ultimately boosting organizational effectiveness and customer satisfaction. It recommends sustained managerial engagement to foster a culture of continuous quality improvement.

Abstract

In recent years, the integration of Artificial Intelligence (AI) in education has transformed how teachers and students interact with learning materials. However, in many teacher education institutions in Nigeria, the use of AI tools in language instruction remains limited and uneven. Lecturers often rely on traditional methods, which restrict students’ exposure to innovative learning technologies that could enhance writing, grammar, comprehension, and communication skills. This gap raises concern about how effectively lecturers are adopting AI to support English Language teaching and learning in Colleges of Education. The study used a descriptive survey design to explore how lecturers and students perceived the use of artificial intelligence in teaching English Language. It was conducted in the Federal Colleges of Education (Technical) at Omoku in Rivers State and Umunze in Anambra State, involving forty-four participants—seventeen lecturers and twenty-seven final-year students. Data were collected through a validated and reliable structured questionnaire analyzed using mean and standard deviation to determine agreement levels on issues relating to AI use in English Language education. The results revealed that lecturers moderately used artificial intelligence (AI) tools in teaching English Language in the Federal Colleges of Education (Technical) at Omoku and Umunze. Findings showed strong agreement that AI supported grammar and punctuation correction (Mean = 3.57, SD = 0.78) and provided instant feedback on assignments (Mean = 2.96, SD = 0.52). The grand mean (3.02, SD = 0.74) indicated moderate adoption. Similarly, AI usage extent was modest (Grand Mean = 2.64, SD =.085), mainly in grammar (Mean = 2.50) and listening comprehension (Mean = 2.60), suggesting gradual but growing integration. The study concluded that while AI has begun to improve teaching effectiveness, its application remains limited. It recommended increased institutional support, lecturer training, and infrastructure development to promote full AI integration in English Language education.
