Tareque; Repon, Md. Reazuddin; Shikder, Abdullah Al Rakib This research work examines how consumer behavior and purchasing pattern are affected by recycled cotton-polyester blended clothing, with a particular emphasis on sustainable apparel merchandising. The use of recycled materials has drawn a lot of attention as environmental sustainability in the fashion business is growing attention. In order to investigate customer behavior, perceptions, preferences and purchasing decisions regarding recycled cotton-polyester blended clothing.This research employed a mixed-methods design that included both qualitative and quantitative methods. For a deeper understanding of the customer attitudes, opinions and motives towards sustainable fashion recycled materials in particular, this phase qualitatively involves a one-on-one interview and focus group discussions based on age, gender social class as well as the level of education. In addition, the study considers aspects such as longevity in use, wear resistance, quality, ease of use and clothing comfort that influence buying decisions. Using data from the qualitative phase as a foundation, the quantitative phase uses surveys given to a broad consumer sample to measure consumer preferences and purchasing pattern for recycled cotton-polyester clothing. This research aims at identifying the key factors that impact the preference of customers and buying behavior for recycled cotton and polyester blends based apparel. Additionally, it aims to assess how well sustainable clothing merchandising techniques work to promote these goods. This study indicates that individuals aged 25–45 from higher social strata and with higher educational attainment exhibit greater awareness and preference for recycled apparel with more than 60 % demonstrating a marked inclination towards these products.

Aminul; Abdullahd, A. B. M.; Hassanb, Md. Sharif; Ibrahim, Suraiya : The objective of this study is to investigate diverse methods of enhancing learning in the fieldof accounting while bridging the gap between academic knowledge and the practical skillsrequired by accounting professionals. The research employed a systematic literature review andutilized bibliometric analysis to assess enriching learning in accounting. Through methodologicalmapping, this research sheds light on emerging trends in the global adoption of newtechnologies, the integration of technology-enabled practices among accounting professionals,and the prevailing preferences influencing revisions to academic curricula in universities andcolleges. Most studies emphasize the importance of integrating technology into accountingclassrooms to enhance the learning experience. Beyond pinpointing the disparity betweenacademic theories and practical accounting needs, this paper provides a robust framework forfurther research into enriching learning in accounting. The findings of this study hold significantimplications for academia, higher education institutions, and policymakers. They underscorethe importance of understanding enriching learning in accounting, as effectivetechnology-enabled teaching and learning strategies play a pivotal role in equipping newgraduates with the skills necessary to pursue their career goals and meet industry standards Article 2024-06-01T00:00:00Z http://dspace.daffodilvarsity.edu.bd:8080/handle/123456789/16191 Analysis of bit error rate and receiver sensitivity of a DC biased optical OFDM transmission link using single mode fiber with distributed Raman amplifier Tithi, Fahmida Hossain; Majumder, Satya Prasad In this paper, an analytical method is presented to assess the performance of bit error rate (BER) of a DC biased optical orthogonal frequency division multiplexing (DCO-OFDM) SMF transmission with distributed Raman amplifier (DRA). Formulas are developed to determine the signal-to-noise ratio (SNR) at the output of a DCO-OFDM receiver and the bit error rate (BER) for an OFDM demodulator’s output. By considering the Gaussian probability density function (pdf) for the OFDM demodulator output, the average BER is calculated numerically. The results are presented based on receiver sensitivity, bit error rate and optical SNR at a given BER of 10−9, with variations in system parameters such as input signal power, data rate, fiber distance, modulation index and OFDM sub-channel number. A comparison of BER performance indicates that DC biased optical OFDM with intensity modulation direct detection (DCO-DD-OFDM) offers better receiver sensitivity compared to optical OFDM without DC bias at a BER of 10−9. Our analytical results align with the published findings on optical OFDM.

Ibrahim; Hasan, Mehedi; Ali, Mir Mohammad; Siddique, Md. Abu Bakar; Senapathi, Venkatramanan; Islam, Abu Reza Md. Towfiqul The global concern over the pollution-induced by microplastics (MPs) has intensified due to its adverse effects on the environment, particularly in terrestrial ecosystems, where it poses potential threats to soil quality and resident species. However, there is a noticeable research gap regarding soil MPs in dumping sites, specifically within the Rohingya Refugee Camp (RRC), the world's largest humanitarian crisis located in Bangladesh. The main objective of this study is to assess soil MPs' abundance, spatial distribution, and inherent risks in the RRC. The investigation involved extracting MPs from ten soil sampling sites in Kutupalong RRC, home to Rohingya refugees who sought refuge in Bangladesh following the 2017 ethnic atrocities in Northern Rakhine State, Myanmar. Stereomicroscopy and Fourier transform infrared spectroscopy were employed for identification purposes. The concentration of MPs in the study area varied from 67 to 126 (items/kg) (dry weight), with a mean concentration of 103.80 ± 20.671 (items/kg). MPs with sizes <0.5 mm constituted the majority at 83 %, with fragments (68 %) being the prevailing shape, and transparent (63 %) as the most abundant color. Predominant polymers included polyethylene (53 %) and polypropylene (46 %). Negative correlations were observed between MP abundance and pH and moisture content (p<0.05), while a positive correlation was found between MP abundance and organic matter. PCA results suggested that human-induced inappropriate waste and air deposition are the primary sources of soil MP pollution. Contamination factor values suggested moderate pollution with MPs in the study area. According to the geo-accumulation index (Igeo), the area was classified as pollution grade II, signifying 'uncontaminated to moderately contaminated.' However, pollutant load index and potential ecological risk index indicated Hazard Level-I and Pollution Grade-I, respectively. This study illuminates the contamination scenario with MPs, underscoring concerns for eco-environmental safety and providing crucial data for future investigations into MPs in terrestrial dumping habitats.
