Rainfall data were collected from CMCC-CM by R programming for two GHGs emission scenarios (RCP 4.5 and RCP 8.5) referred to as ‘Representative Concentration Pathways (RCPs)’. The analysis has been conducted based on four seasons and an annual basis by plotting model data in MS Excel and R programming. The model shows that the average annual rainfall will increase from 1055.6 mm (during 1850-1900) to 1368.1mm (during 2051-2100) for RCP 4.5 while it will reach 1569.7mm (during 2050-2100) for RCP 8.5. Rainfall is also increasing for all seasons except winter. In winter season, the average rainfall will increase from 35.37mm (during 1850-1900) to 41.75mm (during 2051-2100) for RCP 4.5, where it will decrease from 35.37mm (during 1850-1900) to 22.55mm (during 2051-2100) for RCP 8.5 in the study area. The increasing and decreasing trend are more in high GHGs emission scenarios than in the medium, which will be alarming. Accordingly, this projection will be helpful to understand the adverse impacts of climatic elements and take short and long-term planning of decision-makers in that area.\u0000J. Asiat. Soc.

The cerebrospinal fluid (CSF) samples from 371 suspected meningitis cases were examined, and the highest bacterial meningitis was found in 52(14.0%) cases in this study. Among a total of 371 samples of CSF, 272(73.3%) were crystal clear, 52(14.0%) were moderately turbid, 47(12.7%) highly turbid. The total leukocyte cell count of the CSF was proportionate to the turbidity. In the case of crystal clear CSF’s, total leukocyte counts (TLC) were normally ranging from <5 to 45 per mm3 with predominant lymphocytes. Moderately turbid fluid showed 46 to 500 cells per mm3 and highly turbid fluid showed from 501 to more than 10,00 cells/mm3. In the latter cases, differential counts demonstrated polymorphonuclear predominance. In addition, about 100% (52 cases) of positive and 12.5% (40/319) of negative cases had CSF protein concentration >100 mg/dL. CSF protein concentration greater than 100 mg/dl and sugar level below 40 mg/dl were considered as suspected bacterial meningitis in this study. Surprisingly, the C-Reactive Protein (CRP) values were found to be >40 mg/dL in both culturally positive and negative cases. Most of meningitis positive cases showed increased total cell counts as well as protein concentration, and decreased serum sugar concentrations.\u0000J. Asiat. Soc.

Enrolment in education, especially women's education, has reached a desirable level. However, the dropout rate in secondary education is still a concern, which has not been reduced to the desired level. This research aims to understand better the undisclosed causes of dropout at secondary level schools. The primary data were collected from 790 former secondary school level students and 1580 parents/guardians, enabling in-depth and systematic analysis of the issue.. The method used in this study is quantitative with logit analysis. The study results showed that students’ perceptions on education, working experience, low socio-demographic status (SDS), family size, total number of siblings, food deficit, distance of the school, bullied by peers/teachers have a significant effect on increasing the probability of dropping out of school. Contrariwise, parents’ academic support, NGO membership of family members, mobility to the local power structure, and government’s social safety net programmes support are significant variables to reduce the probability of dropping out. The research reveals that financial problems are severely engaged to increase the dropout rate, and non-financial factors together aggressively play a catastrophic role and lead the academic life of the dropout student towards the end. The study suggests authorities for rapid response to reduce dropout, which leads Bangladesh to achieve SDGs targets and eventually become an upper middle-income country by 2041.\u0000J. Asiat. Soc.

In dual culture colony interaction, out of four soil fungi, T. viride was found be the most effective to control the growth of the cotton pathogens. T. viride showed the highest growth inhibition against Curvularia lunata, Fusarium moniliforme, Mucor sp. and Rhizoctonia solani. On the other hand A. niger showed the highest growth inhibition against Fusarium nivale and A. fumigatus showed the maximum growth inhibition against C. gloeosporioides. The highest inhibition of radial growth of C. lunata, F. nivale and F. moniliforme was observed might be due to the secretion of volatile metabolites of T. viride whereas, the maximum inhibition of radial growth of C. gloeosporioides was observed because of the volatile metabolites of A. flavus. Mucor sp. and R. solani were inhibited due to the volatile metabolites of A. fumigatus. The greatest radial growth inhibition of C. lunata and F. moniliforme were noticed in case of T. viride owing to the effect of non-volatile metabolites. On the other hand, the radial growth of C. gloeosporioides and F. nivale were inhibited highest amount for the effect of non-volatile metabolites of A. niger, whereas highest growth inhibition of Mucor sp. and R. solani was observed due to the non-volatile effect of A. fumigatus. The present investigation suggests that the isolates of Aspergillus and Trichoderma may be further exploited as potential biocontrol agents against the fungal pathogens of cotton in field trial. \u0000Asiat.

Mortality and residual effects were statistically different among the plant extracts and doses applied. Neem extract showed the highest adult mortality (36.78%) whereas eucalyptus extract showed the lowest (22.75%). The order of the toxicity of three plant extracts was found as neem > custard apple > eucalyptus. Mortality was found directly proportional to the hour after treatments which increased with the progress of time. Between two solvents, acetone solvent possessed the highest toxicity (mortality 32.95%) but methanol showed the lowest toxicity (mortality 30.56%). The residual toxicity was evaluated on the basis of egg laid, adult emergence, seed infestation and weight loss caused by the insect. The highest residual toxicity was found in neem extract with acetone while the lowest in eucalyptus extract with acetone. Neem extract with acetone and custard apple extract with methanol solvent were found effective to toxic and residual effects against pulse beetle of three plant extracts applied. \u0000Asiat. Soc.
