Effectiveness of Water Hyacinth and Arum Shoot Powders to Remove Cr and Cu from Tannery Effluents

Abstract: AbstractThis research was performed to find out the efficiency of water hyacinth (Eichhornia crassipes) shoot powder (WSP) and arum (Colocasia esculenta) shoot powder (ASP) in eliminating chromium (Cr) and copper (Cu) from tannery wastewater (TWW). For this purpose, WSP and ASP were added to standard solutions (SS) of Cr and Cu; and TWW. Elimination of the metals was inspected in batch processes at diverse contact periods with the identical bio-adsorbent concentration of 5.0 mg L−1. The colour was bottle green and the odour was pungent which were totally absent after the application of the treatment. The maximum Cr was eliminated from the SS and the TWW with the WSP were 85.29% and 87.50% (reduced from 12.0 mg L−1 to 1.5 mg L−1), respectively, at 180 min. The WSP impassive the maximum amount of Cu, 87.96%, from the SS at 180 min, whereas 83.35% was the maximum elimination from the TWW at 120 min. The ASP eliminated the maximum amount of Cr, 79.46%, at 180 min from the SS, whilst 77.08% of the metal was eliminated from the TWW for the same. The maximum amount of Cu, 78.57%, was eliminated from SS at 180 min with the ASP whilst 75.0% was the maximum from the TWW for the same. The WSP was more operative than the ASP in eliminating Cr and Cu from both the solutions.KeywordsArumBatch experimentCrCuRemoval efficiencyTannery waste water

Health-Related Quality of Life and Coping Strategies adopted by COVID-19 survivors: A nationwide cross-sectional study in Bangladesh

Abstract: Abstract This study aims to investigate the health-related quality of life and coping strategies among COVID-19 survivors in Bangladesh. Methods This is a cross-sectional study of 2198 adult, COVID-19 survivors living in Bangladesh. Data were collected from previously diagnosed COVID-19 participants (confirmed by an RT-PCR test) via door-to-door interviews in the eight different divisions in Bangladesh. For data collection, Bengali translated Brief COPE inventory and WHO Brief Quality of Life (WHO-QOLBREF) questionnaires were used. The data collection period was from June 2020 to March 2021. Results Males 72.38% (1591) were more affected by COVID-19 than females 27.62% (607). Age showed significant correlations (p<0.005) with physical, psychological and social relationships; whereas, gender showed only significant correlation with physical health (p<0.001). Marital status, occupation, living area, and co-morbidities showed significant co-relation with all four domains of QoL (p<0.001). Education and affected family members showed significant correlation with physical and social relationship (p<0.001). However, smoking habit showed significant correlations with both social relationship and environment (p<0.001). Age and marital status showed a significant correlation with avoidant coping strategy (p<0.001); whereas gender and co-morbidities showed significant correlation with problem focused coping strategies (p<0.001). Educational qualification, occupation and living area showed significant correlation with all three coping strategies (p<0.001). Conclusion Survivors of COVID-19 showed mixed types of coping strategies; however, the predominant coping strategy was avoidant coping, followed by problem focused coping, with emotion focused coping reported as the least prevalent. Marital status, occupation, living area and co-morbidities showed a greater effect on QoL in all participants. This study represents the real scenario of nationwide health associated quality of life and coping strategy during and beyond the Delta pandemic.

Underlying Aspects in Tagore’s Translation Of Red Oleanders: A Critical Reading

Abstract: Though Rabindranath Tagore’s works have been studied and praised for decades around the world, his struggles to reconcile cultural as well as linguistic differences between English and his native tongue, Bengali through translations of his works have largely been overlooked. This paper though a comparative study between Tagore’s drama Raktakarabi and its translated version Red Oleanders, seeks to find out how Tagore deals with various cultural, literary and linguistic issues that have arisen during the translation and whether the differences between two languages with distinct natures and unique histories have forced him to make fundamental changes to the play. The research also aims to critically look at the reasons behind Red Oleanders’ apparent failure in the west and takes into account relevant translation theories to discuss how various changes to the play have contributed to creating stark contrasts between the original and the translation.

Experimental Study of the Operational Parameters on Low-cost Single-basin Solar Still in Jessore, Bangladesh

Abstract: Keeping in mind the growing concern of sustainability, the present study aims to develop a hands-on technique for potable water production by using a portable single-basin solar still, which is constructed with low-cost, locally available and lightweight materials. The performance of single-basin solar still were investigated using different essential operational variables, which include weather condition, water salinity, brine water depth, and addition of glass marbles as energy absorbing material. Ambient weather conditions were found to have direct effect on the productivity of the still. The solar still productivity increased by 29% when a layer of glass marbles was used. The study also showed that the daily water production increased with the decrease in the initial depth of brine water. Estimating a useful life of 4 years of the solar still, an average cost of produced potable water was defined to be BDT 0.35 per lit. In addition, some important water quality parameters were tested and compared with drinking water standard values. The obtained values were found to be in line with the drinking water standards of WHO. Journal of Chemical Engineering, Vol. 29, No. 1, 2017: 3-8
