Abstract

This research investigates helmet usage rate and motorcyclists’ awareness of road safety laws regarding helmet usage in the Darial Union of Bakerganj Upazila, Bangladesh. A structured questionnaire collected data from 100 participants representing various age groups and professions. Then, data analysis using JASP software revealed significant gaps in helmet usage and awareness of road safety laws regarding helmet usage, particularly among younger individuals aged 15-20 and motorcycle drivers. At the same time, older participants (aged 41 and above) demonstrated higher helmet usage and better understanding; younger riders and those in high-risk professions, such as motorcycle drivers, students, and the unemployed, needed to be more informed and compliant with safety practices. The findings highlight the importance of focused educational efforts and training programs to promote helmet use and raise road safety awareness, particularly in Darial Union's rural districts.

Abstract

This study investigated the impact of natural dyes derived from three plant sources (Eupatorium odoratum, Ageratum conyzoides, and Pueraria phaseoloides) on the bandgap energies of cobalt oxide (CoO) thin films thin films were synthesized using a chemical bath deposition technique at 80-85°C and subsequently annealed at 100°C, 150°C and 200°C. The incorporation of these natural dyes significantly influenced the bandgap energies of the CoO films, with values ranging from 3.80 eV to 4.12 eV depending on the dye and annealing temperature with the as-grown films exhibiting bandgap energies ranging from 3.80 eV to 4.00 eV. Moderate heat treatment typically increased the bandgap of the films, but at higher temperatures, the behavior became more complex, with some dyes demonstrating a substantial reduction in bandgap. These findings demonstrate the potential of utilizing natural dyes to effectively tailor the electronic structure of CoO, offering a sustainable and eco-friendly approach to materials modification.

Abstract

The Hassenzahl framework of UX provides an approach in measuring user experience of a product which covers such the following aspects : be goals, do goals, and motor goals. Yet the further approach for practical implementation in digital product like e-commerce platform is still insufficient. Another approach, the scenario model provides a journey mapping viewing from the user perspective. Thus, generally this method was used to portray the interaction process between user and product. Furthermore, the term of user journey is also commonly used by the UX designer in order to understand what actually the user needs, not just the user want. The solution offered to discuss within this paper is integrating three key elements of Hassenzahl method for every scenario in the e-commerce process. Hopefully the solution as presented on this paper will generate more credible properties and decent tools for developing an efficient, user friendly, and engaging e-commerce application.

Abstract

Water is essential for human life and activities, but its supply depends on the proximity and interconnection network with the populations or cities that need it. Moreso, the proper functioning of water supply systems (WSS) relies on the expertise and experience of field workers who rely on information from maps or field surveys, whose processes and mapping methods are labour-intensive, time-consuming, and are done relatively infrequently. This study explores modern spatial databases for meaningful technical progress using the Quantum Geographic information system (QGIS) server to host a web-based geocoding platform to view the production, transmission, and delivery of drinking water from the source to household users according to the capacities planned for by WSS. The resultant results met expert expectations on the designed web system and showed information on pipe network, road connection, drinking water distribution layout, catchment boundary, slope, and sub-catchment geometric properties demonstrating the utility of a web-based online Map plugin in the GIS environment as a data management, scenario analysis, and decision support tool in managing water infrastructure for an expanding metropolitan city like Ilorin, Kwara State.

Abstract

The present study investigates the effect of the concentration of flexible resin on the dimensional accuracy of mixtures product manufactured by 3D printing using SLA technology. Specimens were designed and according to the ASTM D412 standard. Ten variations of resin mixtures were examined. The concentrations of the flexible resins were varied from 10% to 100%. Measurements of accuracy dimension were conducted on the fabricated specimens, and the average deviation was used to estimate the dimensional accuracy. The study reveals the least deviation in dimensions in the 10% flexible resin containing mixture and the highest in the 60% flexible resin containing mixture. The results explain the fabrication tendency of flexible resins in dimensional accuracy for 3D printing.
