No full textThe study examined pupil leadership and discipline maintenance among pupils in primary schools of Muko Sub County Rubanda District. The problem statement is that despite the role that pupil leadership plays in maintaining discipline among the pupils in primary schools in the Muko sub-county Rubanda district has continued to experience a crisis of pupils' discipline, which is primarily manifested through pupils' violence, avoiding lessons, and escapism from the schools which has affected their academic performance (Education department report Rubanda district, 2022). The objectives of the study were; to examine the effect of pupil leadership on discipline maintenance among pupils of the selected primary schools, to examine the challenges faced in discipline maintenance among pupils’ of the selected primary schools, and to investigate how discipline can be maintained among pupils’ in the selected primary schools. A descriptive study design was used and data was collected using interviews and questionnaires. The results from this study showed that pupil leadership helps in establishing order in the school, encourages self-discipline and accountability, encourages compliance with school rules and cooperation, pupil leadership helps in the promotion of school values, helps pupils organize and engage in positive activities and pupil leadership helps in support for teachers and other staff. In addition, pupils' age and developmental differences, lack of understanding of consequences, home environment and background, inconsistency in applying disciplinary measures, limited resources and support in the school, lack of parental involvement, and negative influences from peers as challenges faced in discipline maintenance among pupils. Provision of clear and consistent rules, ensuring better classroom management, teachers and staff should act as positive role models for the pupils, ensuring parental involvement in the education process, incorporating social and emotional learning programs into the school curriculum to help pupils develop emotional intelligence and implementing anti-bullying programs to create a safe and inclusive environment for all pupils are the measures of discipline maintenance among pupils’ in the selected primary schools that were mentioned. The study recommended that there should be formation of relevant rules to the developmental stage of the pupils for instance, younger pupils need rules that are easy to remember to maintain discipline among pupils in primary schools

Optimal Pavement Maintenance Strategy Based on the Relationship Between Pavement Condition Index and Roughness
No full textPavement maintenance is crucial for ensuring road safety, reducing congestion, and minimizing repair costs. However, determining the optimal timing and strategy for pavement maintenance remains a challenge. This study investigated the correlation between the Pavement Condition Index (PCI) and Roughness Index (RI) to develop a numerical model for describing relationship of the two indices for pavement maintenance decision-making. Using statistical analysis and data visualization techniques, a significant correlation was found between PCI and RI. The study revealed a moderate correlation between PCI and IRI (R² = 0.47), indicating that 47% of PCI variations can be explained by IRI. While this suggests that the model is capturing a significant amount of the relationship between PCI and IRI, there is still room for improvement, as about 53% of the variance in PCI is not explained by the model. Since the PCI is a measure of road pavement conditions (on a scale typically ranging from 0 to 100), an RMSE of 7.77 means that the model's predictions for PCI are, on average, about 7 to 8 PCI units off from the actual value. The study established a clear relationship between pavement condition and surface roughness, enabling the development of a model to guide maintenance decisions. The study recommends prioritizing roads with PCI ≥ 50.3 and RI ≤ 5.12 m/km, alongside regular monitoring to ensure timely, cost-effective maintenance. Regular monitoring of PCI and RI values is also recommended to ensure timely maintenance and prevent costly repairs

No full textThis study examined the impact of land use practices on land cover in Bubare sub-county, Rubanda district, addressing three main objectives: to identify and characterize land use practices in Bubare, to assess how farming systems influence forest cover, and to evaluate the effectiveness of land use policies in managing local land resources. Data were collected from 132 respondents, including Bubare sub-county staff, local leaders, and community members, using questionnaires and interview guides. Descriptive statistics were analyzed with Microsoft Excel, and the findings were presented in tables, charts, and graphs. The results revealed the presence of various policies and laws governing land use and land cover, including the National Land Use Policy (14%), the National Land Act (20%), the Land Act of 1998 (10%), the Uganda National Land Policy 2013 (16%), and local policies or regulations (40%). Most respondents (40%) indicated that local policies or rules governing land and soil conservation were the primary policies used in Bubare sub-county. The findings also indicated that land use practices impacted the environment, with outcomes such as improved crop quality (18%), increased yield per acre (20%), and enhanced food security (36%). The study recommends that farmers apply manure and fertilizers to enhance yield quality and quantity and promote food production. The use of farmyard manure should be encouraged to restore land cover, alongside sustainable farming practices like crop rotation and rotational grazing to prevent land degradation. Additionally, policies should be developed to promote afforestation, reduce deforestation, and educate the community on the responsible use of land to prevent environmental damage
Investigating a Suitable Ratio of Iron Ore Tailings and Quarry Dust in Concrete Production.
No full textConcrete is the most widely used construction material, man consumes no material except water in such a tremendous quantity. Concrete is a homogeneous mixture of cement, coarse and fine aggregates, and water which consolidates into hard mass due to the chemical reaction between the cement and water, but its production has significant environmental consequences, including high carbon emissions and natural resource depletion. As a result, there is an increasing interest in the development of sustainable concrete technologies that reduce concrete's environmental footprint while maintaining its performance and durability. Sustainable development is a development that meets the needs of the present without compromising the ability of future generations to meet their own needs. Iron ore tailings are the residual materials left over after the extraction of iron ore from its ore body on the other hand quarry dust is a fine-grained material produced as a by-product of quarrying operations. It is typically composed of crushed stone, sand, and other mineral particles. The main objective of this study is to investigate a suitable ratio of iron ore tailings and quarry dust in concrete production by determining the physical properties of fine aggregate, designing a concrete mix conducting mechanical tests, and conducting a comparative study between the effect of Buhara IOT and Ntungoma quarry dust. IOT gives a Cu of 6.3 and quarry dust a Cu of 7.5 and they are both greater than 4 implying that both are well-graded materials. Higher values of Cu imply that D60 is significantly larger than D10. This means that both larger and smaller particles a present in significant quantities. The fineness modulus of quarry dust is 3 and that of IOT is 3.5 implying that IOT has a higher percentage of coarse particles. IOT particles produced a higher density than both quarry dust particles and coarse aggregates combined. Quarry dust had a greater water absorption than iron ore tailings because it had more quantities of finer aggregates than iron tailings making it absorb more water. workability increased with an increase in the percentage of quarry dust and at 80% quarry dust and 20% IOT obtained the highest slump value of 35mm, Compressive strength increased with an increase in quarry dust percentages. Maximum percentage was obtained at 80% quarry dust and 20% IOT. At 28 days we obtained the maximum compressive strength of 19Mpa
