    Adolescents’ perception on extracurricular spaces: a comprehensive exploration of adolescent play lab
    (BRAC University, 2025-07) Nusrat, Nazia; Nahrin, Wasima
    This study explores adolescents’ overall experiences, perceptions, and playful behaviors within the Adolescent Play Lab (APL) in rural Bangladesh. Conducted in four government schools, the research employs a mixed-methods approach, combining surveys, focus group discussions, and observations. The findings suggest that most adolescents view the APL as a positive and engaging environment that promotes creativity, social interaction, and a sense of belonging. Adolescents report enjoying group activities, feeling motivated to participate, and experiencing increased social connectedness. However, some challenges, including limited space and occasional boredom, were noted, highlighting areas for improvement. The study underscores the importance of well-designed play environments in supporting adolescent development, while also identifying issues such as space constraints and gender-related participation gaps. It concludes that incorporating adolescents' feedback is crucial for creating inclusive and meaningful extracurricular spaces, and that minor adjustments in space and activity planning can significantly enhance their experiences.

    Analysis of Polarization Maintaining Optical Fibers under External Stress
    (Eastern University, 2013-12-01) Zaki, Farzana Rahmat; Nusrat, Nazia
    This present study is on detailed physical explanation of stress- induced birefringence in Step index polarization , maintaining elliptical core optical fibers. The birefringence is a Quadratic function of the effective index change, which may occur due to changes of stress Distribution within a material. In this study, changes in birefringence have been observed By applying lateral pressures. The effects on birefringence with changing ellipticity of Core of the fiber have been observed by applying no pressure. Pressure along x-axis and y-axis On the optical fiber. Finally, the birefringence of an optical fiber resulting from an Asymmetry of the index profile has been numerically evaluated using finite-element Method (FEM).
