Assessment Of Public Transport Quality And Reliability (Long-Distance Bus Service) In Dhaka, Bangladesh Siddique, Pavel; Hasan, Ferdaws This thesis investigates the quality and reliability of public transportation services in Dhaka Bangladesh, focusing specifically on long-distance bus services. Two major routes Dhaka to Rajshahi (route 1) and Dhaka to Chattogram (route 2) were selected due to their significance in connecting key urban areas and their high passenger volumes. A survey was conducted using a structured questionnaire distributed at the Dhaka Gabtoli terminal, capturing passenger feedback on satisfaction, frequency of service, affordability, comfort, safety, punctuality, availability of information and personal courtesy. Data collection occurred during peak travel times in the afternoon and evening, as well as on off-days, ensuring a diverse representation of passenger experiences. The gathered data was meticulously analyzed using Excel, allowing for both quantitative and qualitative assessments of service quality. Findings reveal critical insights into common challenges faced by passengers, highlighting significant differences between the two routes. The study identifies areas for improvement and offers actionable recommendations to enhance the reliability and standard of public transportation in Bangladesh. By addressing these issues, this research aims to contribute to the development of more efficient and user-friendly transportation systems, ultimately supporting broader economic growth and mobility within the country.

Sustainable Potential of Recycled Textile Cotton Fiber Reinforced Concrete Beam Nandi, Jagodish; Matubber, Muzahid; Islam, Md. Mirazul The construction industry significantly contributes to environmental degradation due to its high consumption of natural resources and waste production. To address these challenges, a growing interest is in developing sustainable construction materials that can reduce the industry's environmental footprint. This study explores the sustainable potential of recycled textile cotton fiber as a reinforcement material in concrete beams. Recycled cotton fibers, derived from textile waste, offer an eco-friendly substitute toconventional reinforcement materials, providing both waste management solutions and enhanced material properties. Consider how much the beam deflection and load are reduced or increased when replaced with steel-reinforced beams and consider where the textile reinforcement canbe used. A comparison of flexural behavior is made between reinforcement concrete beams and textile-reinforced concrete beams. Two different beams were constructed for comparison with reinforcement concrete beams. The research investigates the mechanical properties, durability, and environmental impact of recycled cotton fiber-reinforced concrete (RCFRC) beams through a series of experimental tests. Results indicate that incorporating recycled textile cotton fiber reinforced concrete beams can't be better than reinforced concrete beams the tensile strength, flexibility, and crack resistance of concrete beams while reducing the carbon footprint associated with traditional concrete production. Additionally, the use of recycled fibers aligns with circular economy principles, promoting resource efficiency and waste reduction. The reason for the research was to compare steel reinforcement concrete beams and what steel can be. Thesis

Observation of Hospital Waste Management System In Savar Area, Bangladesh Meraz, Md Jannatul Ferdous This research examines the management procedures of hospital waste in public and private healthcare institutions in Savar Area, Dhaka, Bangladesh. The study seeks to assess current waste management systems, pinpoint significant difficulties, and suggestpractical changes to improve public health and environmental safety. A mixed-methods strategy, utilizing both quantitative and qualitative data collection techniques, was employed to provide comprehensive insights. Field surveys, interviews with hospitalstaff, and direct on-site inspections were performed at 10 hospitals, comprising 1 public and 9 private institutions, with responses gathered from around 100 individuals engaged in waste management. The findings indicate substantial discrepancies between hospitals' compliance with the Medical Waste Management and Processing Rules (2008) and their actual execution. Identified common categories of hazardous wasteinclude infectious waste, pathological and anatomical waste, and hazardous pharmaceutical and chemical waste, with no hospitals producing radioactive waste. Private hospitals demonstrated greater adherence to waste management protocols than public hospitals; nonetheless, all institutions encounter difficulties, including inadequate staff training, limited infrastructure, ineffective waste segregation, and financial limitations. The survey of hospitals revealed that the most commonly produced wastes are blood and blood products, bandages, and dressings, while the least produced wastes are human organs and expired medicines. Moreover, the majority of hospitals depend on an external waste management company, PRISM Bangladesh, for the collection and treatment of hazardous waste utilizing techniques such as autoclaving, incineration, and landfilling. The study indicates that, notwithstanding the presence of a legislative framework, significant enhancements are required to guarantee successful hazardous waste management. It is recommended that according to Medical Waste Management and Processing Rules (2008) encompass the establishment of a 4-bin waste segregation system, improved staff training initiatives, intensified regulatory control, and augmented governmental investment in waste treatment technologies. The study emphasizes the necessity for coordinated actions by governmental bodies and healthcare organizations to enhance hazardous waste management and protect public health and the environment in Bangladesh.

Modeling and Load Analysis Slab Bridge on Diu Lake Bridge Akash, Md. Alif Chowdhury The increasing pace of urbanization and infrastructure growth is making complex transportation systems increasingly required. This condition along with additional constraints for aligning the bridges correctly are what allow an increasing number of slab bridges to be built. Slab bridges are commonly employed in rural planning when geometry makes it impossible to build the appropriate bridges. In this paper, the behavioral properties of slab bridges are analyzed and compared with straight bridges using CSI-Bridge Analysis software. At critical places where the slab bridge has an influence, the maximum bending moment, maximum shear force, maximum torsional moment, maximum deflection from dead load, and maximum deflection from live load are all shown. IRC Class Hsn-44 live load Tracked Vehicle and Moving load VECL1 Load case define vehicle class HL-93S, HL-93K, HL-93M, all load case use AASHTO code 2014.The highest tensile forces and sheer are found at the ends and lower portion of slab bridges, where reinforcing steel rods are twisted or roughened. Slab bridges are made up of a single, flat concrete beam known as a slab. The amount of steel and depth are chosen based on the length and live-load capacity of the slab. Powerful Simply supported bridges are made up of horizontal beams connected across a single span, and continuous slab bridges are made up of beams connected over two or more spans. Substructure modules provide support for slab bridges at both ends. Thesis
