Body image satisfaction is an important psychological construct that influences mental health and well-being, yet culturally adapted and validated tools are limited in Bangladesh. This study aimed to evaluate the psychometric properties of the Bangla Body Image States Scale (B-BISS) for measuring momentary body image states. A total of 579 young adults aged between 19 and 28 years, primarily university students of Bangladesh, were recruited through convenience sampling. Exploratory factor analysis (EFA) supported a unidimensional structure, with a single factor explaining 82.5% of the variance. This structure was further confirmed by confirmatory factor analysis (CFA), which demonstrated excellent model fit (CFI = 0.99, TLI = 0.99, SRMR = 0.03, RMSEA = 0.10). Internal consistency was excellent, with Cronbach’s α = 0.97 and McDonald’s &omega; = 0.97. Measurement invariance indicated that the scale can be applied in the same way across gender. Additionally, convergent validity was established through significant correlations with related constructs, including psychological distress and self-compassion. B-BISS had positive association with self-compassion ( r = 0.13, p <.001) and negative with psychological distress, including depression ( r = -0.16, p <.001), anxiety ( r = -0.09, p <.05), and stress ( r = -0.12, p <.01). Overall, the B-BISS demonstrated robust psychometric properties, confirming its suitability as a sound measure for assessing body image states among young adults in Bangladesh. Measuring body image states can offer psychologists, psychotherapists, and researchers a better understanding of body image concerns and the targeted interventions to have better momentary body image states in young adults of Bangladesh.

In this current study, five types of strong, stiff, and lightweight composites were developed utilizing hand lay-up and cold press methods by the hybridization of JUCO and carbon fabrics. Before the fabrication of the composites, the surfaces of the JUCO fabrics were treated with a 5% NaOH aqueous solution. To evaluate and compare the mechanical characteristics of the fabricated composites, tensile, flexural, impact, and hardness tests were conducted. Specimens were also aged in artificial seawater (pH 8) for 150 days to explore the effects of seawater aging on the mechanical characteristics of the composites. Numerical analysis of the tensile and flexural properties was also done by the finite element method ( FEM ). The findings from the current study showed that hybridization with carbon fibers considerably enhanced the mechanical properties of the natural fiber-reinforced composites. On the other hand, a decrement in tensile strength, flexural strength, and hardness, and an improvement in impact strength were noticed due to fiber degradation as a result of aging in seawater. Results obtained from the numerical analysis also displayed good alignment with the experimental findings.

This study is devoted to the development of lightweight Aluminum alloy to reduce energy consumption and environment pollution in automobile sector. Aluminum alloy shows impressive strength though they are lightweight. The effect of Cu on Al-5.5Zn-2.5Mg-xCu alloy has been studied and improvement in mechanical properties within a range has been observed. The optical microstructure confirmed the formation of Cu enriched brittle phase by solid solution strengthening and it accelerates the hardness and tensile strength. After certain limit strength followed the opposite trend so the material can be used as high strength material when the Cu content will be in a certain limit. In automobile sector vehicle parts made with this alloy material has less weight than commonly used steel. The total weight reduction of a vehicle will reduce the energy consumption which will ultimately eliminate the emission of environment pollutant gas.
