Recyclable Waste Collection Routing in Households’ Areas Using the Mtz-Tsp Model – A Case Study in Rasah, Negeri Sembilan

2023-09-04T06:17:10+00:00

Sustainable household waste management is crucial for any nation. Currently, Malaysia relies heavily on landfilling as a waste disposal method. Unfortunately, most of the waste disposed of is recyclable. One of the contributing factors to householders' unwillingness to recycle is inadequate collection systems. The implementation of an efficient system for collecting recyclable waste would contribute to the improvement of Malaysia's waste management infrastructure, particularly regarding the restricted availability of suitable landfill space in the future. Therefore, this study employed the Miller-Tucker-Zimmer Travelling Salesmen Problem (MTZ-TSP) as a framework to address the issue of collection routing for recyclable material within household areas. For our research study, we have selected twelve households in Rasah, a suburban neighborhood located in Negeri Sembilan, as the empirical preliminary work. It took less than 150 minutes to collect the recyclables from these twelve households.

Prediting Mathematics Student S’ Learning Outcomes in Senior Secondary School using Dimensions of Academic Engagement

2023-09-14T12:02:20+00:00

Academic engagement is a potential antidote to issues surrounding students’ learning outcomes. It is a multidimensional construct, which comprises of three aspects such as; emotional, cognitive and behavioural engagement. These dimensions are vital to one another and should not be considered in isolation. This paper investigated the dimensions of students’ academic engagement as predictors of male and female self-efficacy in and attitude to Senior Secondary School Mathematics. The study used an ex-post facto correlation approach. 1680 students from Senior Secondary School Two made up the study's sample from the twenty one randomly selected schools in the three Local Government Areas of Remo division of Ogun State. Three instruments were used namely, Mathematics Student Academic Engagement Scale (MSAES) with; Mathematics Attitude Scale (MAS) withand Mathematics Self Efficacy Scale (MSES) with Findings showed a significant contribution in male students’ attitude to Mathematics (F = 149.857, p<0.05) and self-efficacy in Mathematics (F = 146.368, p<0.05). The study revealed that the predictor factors significantly explain the variation in female students' attitudes toward mathematics when they are combined (F = 182.978, p<0.05) and self-efficacy in Mathematics (F = 239.960, p<0.05). This study concluded that cognitive, emotional and behavioural engagements are good predictors of the secondary school mathematics self-efficacy and attitude of male and female students. To increase students' self-efficacy in and attitude toward mathematics, stakeholders in Nigerian education are advised to make sure that students are engaged cognitively, emotionally, and behaviourally.

Mathematical Modeling and Control Strategies for Nipah Virus Transmission Incorporating Bat-To-Pig-To-Human Pathway

2023-11-13T21:04:59+00:00

The mathematical modeling of Nipah virus transmission, incorporating the bat-to-pig-to-human pathway, is essential for understanding this disease dynamics and optimizing control measures. Nipah virus, which naturally resides in animals, particularly fruit bats, spreads to humans via intermediate hosts like pigs. This research work highlights the significance of including this pathway in mathematical models for several crucial reasons. Firstly, it aids in comprehending zoonotic transmission, essential for designing effective control strategies. Secondly, it facilitates early detection and intervention by encompassing bats, pigs, and humans in the model. Monitoring factors such as bat population dynamics, pig infections, and human exposure enables timely intervention to prevent or mitigate outbreaks. Moreover, the complexity of Nipah virus transmission involving multiple species underscores the need for multifaceted control measures. We present a detailed mathematical model for Nipah virus transmission, including equations for human, pig, and bird populations. The model is rigorously analyzed, including the calculation of the basic reproduction number, the local stability of disease-free equilibrium, and the global stability of the equilibrium. Sensitivity analysis is performed to identify parameters with the most significant impact on disease dynamics. Optimal control strategies for the Nipah virus, incorporating personal prevention, treatment, biosecurity, and public health interventions, are developed and analyzed. Numerical simulations demonstrate the effectiveness of these control measures in reducing human and pig infections.

This research equips health practitioners with valuable insights and tools to better understand, prevent, and manage Nipah virus infections. Incorporating the bat-to-pig-to-human transmission pathway into mathematical models, provides a more holistic view of the disease's dynamics and enables health practitioners to implement more effective strategies for disease prevention and outbreak control.

Incorporation of Graphene Oxide/Metal Oxide into Modified Polyvinylidene Fluoride Membrane for the Degradation of Methylene Blue Dye through Adsorption-Photocatalytic Activity

2024-02-11T03:23:04+00:00

Recent studies have demonstrated substantial advancements in the treatment of dye wastewater through the synergistic incorporation of graphene oxide (GO) and metal oxide. This research focuses on the successful fabrication of a GO-based composite membrane using the non-solvent induced phase separation (NIPS) method. Two distinct metal oxides, titanium dioxide (TiO₂) and zinc oxide (ZnO), were incorporated into polyvinylidene fluoride (PVDF) as the membrane carrier. The resulting membranes, namely PVDF/TiO2, PVDF/ZnO, and PVDF/TiO2/GO, were developed as photocatalyst membranes for the treatment of methylene blue (MB) dye contamination through adsorption-photocatalytic activity. The adsorption process was conducted for 30 minutes before initiating the photocatalytic activity. Upon UV-Vis measurement, the PVDF/TiO₂/GO composite membrane exhibited superior dye degradation efficiency, reaching 91.89%, as compared to PVDF/TiO₂ (91.38%) and PVDF/ZnO membrane (86.80%). This noteworthy enhancement in dye degradation performance, positions the PVDF/TiO2/GO composite membrane as a promising candidate for applications as a photocatalyst in the treatment of dye wastewater. The results underscore the potential effectiveness of this composite membrane in addressing environmental challenges associated with dye pollution.

Evaluating eco-friendly soil neutralizers: The use of pulverized eggshells and clam shells in enhancing rice field soil acidity

2024-02-20T02:56:16+00:00

Soil acidity is an important factor in the yield of rice crops. This article aims to determine the effectiveness of alternative soil neutralizers in agricultural land in the form of utilizing the calcium carbonate and calcium oxide content of pulverized eggshells and clam shells. This study used an independent T-test to determine the difference between the alternative soil neutralizer and commercially- made soil. A total of 45 samples were gathered: these are, along the side of the road, along the irrigation, and away from the road and irrigation. These sites are divided into 4 corners, 1 at the center, and then by 3 based on the depth of the soil sample, separated by 6 inches from top, middle, and bottom. The soil samples were mixed with these neutralizers with a 1:1:2 ratio and recorded a day, three days, and seven days. When mixed with the alternative neutralizers, the results showed a mean of 7.71 pH after seven days while the commercial neutralizers showed a mean of 7.84 pH. The result shows that the alternative neutralizers have a very close value to commercial neutralizers which indicates that they can be used to solve soil acidity at a lower expense. Although the T-test results showed that there is a significant difference between the two neutralizers with a 0.0044 pH value, the difference is just very little and still exhibits an effective result. This implies that the alternative soil neutralizer could be used as an effective, cost-efficient, and eco-friendly substitute.
