Alternatively, bio-fertilizer can be used to increase the productivity and sustainability of soil without causing environmental pollution. The present study aimed to cost-effectively produce bio-fertilizer using agricultural residues and determine the shelflife and efficacy of the bioinoculants. We used sterilized rice husk ash and alluvial soil (1:2) to prepare cost-effective carriers. Rhizobium sp., Azotobacter sp., and Trichoderma sp. were grown in a newly designed culture medium for economic production as bio-inoculants. The efficacy of the formulated bio-fertilizer was tested on a small scale, where it significantly improved the growth of the sponge gourd (Luffa aegyptiaca) plant (p<0.01). The formulated bio-fertilizers were stored at room temperature for one year. Initially, the total viable count of microorganisms was 8.0×107 CFU/g in the formulated bio-fertilizer. The total viable count of the bio-inoculants increased significantly after one month (2.2×108 CFU/g) and one year (2.2×109 CFU/g). Rice husk ash might have supported the growth and survival of the bioinoculants under room temperature (25°C) because of its nutrient retention capacity, adsorptive capability, and high content of silica. Therefore, this study suggests that sterile rice husk ash combined with alluvial soil can be used as a carrier for bio-fertilizers formulation with Rhizobium sp., Azotobacter sp., and Trichoderma sp. bioinoculants.\u0000Dhaka Univ.

Additionally, this study optimized fermentation conditions for the potential yeast strains and compared their leavening efficacy and biomass production with locally available commercial dried yeast (DY1) in Bangladesh. A total of thirty-five yeast strains were isolated from twenty-five indigenous fruit samples such as Mango (Mangifera indica L.), Jackfruit (Artocarpus heterophyllus Lam.), Papaya (Carica papaya L.), Litchi (Litchi chinensis Sonn.) and Banana (Musa oranta Roxb.). Based on bread leavening efficacy, four potential baker’s yeast strains (Man5, Ban2, Man9, and Ban5) were selected for characterization as potential baker’s yeast. Based on biochemical properties, API kit-based identification, and PCR-based molecular identification, all newly isolated yeast strains were identified as S. cerevisiae. None of these isolates produced H2S. Man5 and Ban5 isolates flocculated at a level comparable to the DY1. All strains showed better temperature tolerance (up to 45°C) than DY1. Man5 and Man9 also showed maximum ethanol tolerance (up to 16%). Only DY1 and Man5 increased dough volume significantly compared with other strains (p< 0.05). Notably, in the optimized growth condition, the Man5 strain produced the highest biomass significantly compared with others (p< 0.05). From the present study, it is concluded that the indigenous strain Man5, Man9, and Ban5 have the potential to be used in the industry as a substitute for imported baker’s yeast in Bangladesh and that will save a substantial amount of foreign currency.\u0000Dhaka Univ.

Apart from the evident physical symptoms in infected cases, it has caused serious damage to public mental health. The current research is an attempt to explore mental health and psychological distress of the Covid-19 frontline workers. One hundred and seventy-seven Covid frontline workers (88 male and 89 female) were asked to complete a questionnaire with questions about symptoms of depression, anxiety, stress, and mental health. The questionnaire included Depression, Anxiety and Stress Scales (DASS-21) and the Bangla version of the General Health Questionnaire (GHQ-12). The results revealed that mental health was negatively correlated with stress, anxiety, and depression. Both male and female frontline workers reported mild to moderate levels of depression, anxiety, and stress. Females reported significantly higher stress than males. However, frontline workers from different professions did not differ significantly on depression, anxiety, stress, and mental health. The findings point to develop strategy to support the mental health of frontline workers including designing psychological support and resilience-building interventions based on risk factors.\u0000Dhaka Univ.

However, the ecological impacts of the marine fishing bans on water quality and hilsa’s growth are not assessed yet. Thus, this study aims to contribute here using data from coastal waters and fish from pre-contacted fishers in the Nijhum Dwip seascape during and outside the fishing ban in 2021 – 2022. Data were analyzed using R software. The measured mean dissolved oxygen, temperature, pH, electrical conductivity, total dissolved solids, and transparency of the sample water were 7.1 ± 1.13 mg/l, 31.1 ± 0.71°C, 8.45 ± 0.07, 40000 ± 2828 μS/cm, 18000 ± 1414 mg/L and 63.5 ± 2.12 cm at 1 week prior to the ban ends (July) and 8.45 ± 0.21 mg/l, 22.35 ± 0.49°C, 8.45 ± 0.07, 20500 ± 1060.66 μS/cm, 10350 ± 212.13 mg/l and 63.5 ± 7.78 cm before the ban starts (February). The values might be varied due to seasonal differences. The mean length (38 cm) and weight (601 g) of sampled hilsa during the ban periodwere comparatively larger than the mean length (29 cm) and weight (229 g) of hilsa which were sampled during the outside fishing ban period. Therefore, this study concludes that the marine fishing ban has positive impact on the growth and size of hilsa. This study suggests that further research is required to assess the fishing ban’s impact on the growth and production of other coastal and marine fish species across the Bay of Bengal.\u0000Dhaka Univ.

Most of the samples were found deficient in Zn and B, while a moderate number of samples were Fedeficient. The major reason of micronutrient deficiency was found to be high soil pH. Among the four soil series studied, Ghior series was most deficient in Zn and B, implying pedogenic differences among the soils. Significant effect of contrasting land types on the distribution of soil micronutrients was observed although the effect was not consistent. The rice-rice cropping pattern was found to have slightly higher contents of Mn, Zn and B compared to rice-non-rice pattern which might be due to longer submergence period in the soils under rice-rice pattern.\u0000Dhaka Univ.

Previous research also indicates that an individual’s cognitive emotion regulation (CER) and autonomy is correlated. The present study aimed to gain more insight into the relationship between autonomy and cognitive emotion regulation of Bangladeshi adolescents. Cross sectional survey design was used covering 100 adolescents having an age range of 12-15 years of age for data collection. Participants completed the questionnaires including a demographic questionnaire, adolescent autonomy questionnaire and cognitive emotion regulation questionnaire. Correlation analysis suggests that autonomy support showed an increase in the adaptive emotion regulation. Regression analysis models revealed that adolescent autonomy significantly explained 14.6% of variance for adaptive emotion regulation, and 4.6% of variance for less adaptive emotion regulation. Findings from the present study embodied that Bangladeshi adolescents use more adaptive cognitive regulation than maladaptive emotion regulation. These findings have implications for parents, primary caregivers, child psychologists, and other relevant professionals who are and will be working with children/ adolescents in helping them to learn and enhance their autonomy for their future and effective cognitive regulation of emotion.\u0000Dhaka Univ.
