  • Factors of Using Long Acting and Permanent Methods (LAPM) of
           Contraception: Bangladesh Perspective

    • Authors: Bikash Pal, Abu Zar Md Shafiullah
      Pages: 87 - 94
      Abstract: The Government of Bangladesh is very much aware of controlling excessive birth rate to maintain population problem. Though Bangladesh is owning self-sufficiency in many sectors, the increasing population is a great impediment for the development of the country. So, promoting different contraceptive methods is of much importance. This work aims at identifying the important determinants that affect the long-acting and permanent methods (LAPM) of contraception. Firstly, chi-square test of association is carried out for defining the correlates of LAPM of contraception using Bangladesh Demographic and Health Survey (BDHS), 2017-18 data. For estimating the effects of each controlled independent variables, data are further analyzed within a multivariate framework. To obtain consistent and efficient estimates of parameters of interest, multinomial logistic regression model is used in this work. The study finds several socio-economic and demographic variables having high impact on using LAPM. The study findings are properly discussed and recommendations are made accordingly for the policy makers. Dhaka Univ. J. Sci. 71(2): 87-94, 2023 (July)

  • Development of Cost-Effective Fuel Briquette with Poultry Manure

    • Authors: S M Nasif Shams, A M Mahmudul Hasan, Shams Bin Bony Amin, Gour Chand Mazumder
      Pages: 95 - 103
      Abstract: Biomass can be converted into either heat energy or electrical or energy carriers using both thermo-chemical and bio-chemical conversion. Briquetting is a process where untreated biomass is converted into homogeneous, uniformly sized high density solid blocks. Briquettes are used in boilers, heating plants, thermal power stations and by individual households for heating. Present study focuses on using poultry manure with rice husk and saw dust. Poultry manure mixed with rice husk or saw dust by 60:40 ratio provides comparatively higher bond strength. Calorific value varies significantly with the use of poultry manure and tree leaves as well as its production cost. Pure rice husk contains higher calorific value (HCV) 12.6 MJ/Kg where adding poultry manure reduces its value to 10.3 MJ/Kg and Saw dust shows 10.4 MJ/Kg where pure saw dust has 16.3 MJ/Kg in 60:40 ratios with poultry manure. Addition of 20% tree leaves on weight basis ratio of 40:40:20 with base materials and poultry manure shows 10.5 MJ/Kg and 11.7 MJ/Kg respectively for rice husk and saw dust. Competitive price of briquette for 60:40 ratios with Poultry Manure shows 6 BDT/Kg and 5BDT/Kg when secondary material is added. Moreover, if the machine capacity increases the price is reduced.

  • Determination of Non-linear Refractive Index of Pure SnO2 and TiO2 Doped
           SnO2 Thin Films Using Z-scan Technique

    • Authors: PD Gupta, Ishtiaque M Syed
      Pages: 104 - 110
      Abstract: In this research work the non-linear refractive indices n2 was determined for the pure SnO2 and TiO2 doped SnO2 thin films by using the Z-scan technique. We have used a continuous wave Ar-ion laser with incident wavelength of 514 nm as the source. n2 was measured by varying three quantities: the incident laser intensity, thickness of the pure SnO2 films and doping concentration of TiO2 in SnO2 films. From the experimental results, the values of n2 were found to be increasing with the increase of thickness of the pure SnO2 films and also with the increase of doping concentration of TiO2 in SnO2 thin films.

  • Preparation of Some as-Triazines, Their Evaluation as Spectrophotometric
           Reagents and Determination of Trace Amount of Iron in Certain Food and
           Natural Samples

    • Authors: Maksuda Parvin, Munira Mushtari, Afifa Rahman, Nazmin Akter, Md Anwarul Islam
      Pages: 111 - 116
      Abstract: Spectrophotometric reagents 3-(2-pyridyl)-5,6-diphenyl-1,2,4-triazine (PDT) and 3-(2-pyridyl)-5,6-bis(p-methoxyphenyl)- 1,2,4-triazine (PBMPT) were prepared from commercially available reactants simply by condensing pyridyl-2-hydrazidine with 1,2-dicarbonyl compounds. These organic reagents were used further to determine the trace amount of iron in various natural and food samples by spectrophotometric method. The absorptiometric features of iron (II) complexes of PDT and PBMPT were determined. The molar absorptivites of iron (II) complexes of PDT and PBMPT were found to be 24,181 L mol-1 cm-1 (at 556.0 nm) and 32,091 L mol-1 cm-1 at (561.8 nm) respectively. The reliability of these absorptivities were verified by standard addition technique and also by comparing the results of atomic absorption spectroscopy method. The complexes of both the reagents obey Beer’s law within the experimental concentration range 0.032mg/L - 0.159 mg/L. Dhaka Univ. J. Sci. 71(2): 111-116, 2023 (July)

  • Determinants of Caesarean Section in Bangladesh: A Multilevel Analysis of
           BDHS 2017-2018 Data

    • Authors: M Ershadul Haque, Sabina Sharmin, Sayema Sharmin
      Pages: 117 - 126
      Abstract: In recent years Caesarean Section (C-S)is considered as an important mode of child delivery in lowering mother and infant mortality. However, the unnecessary use of C-S has detrimental impacts on both mothers’ and newborns’ health. The purpose of this study is to evaluate the prevalence of caesarean delivery and to find out the related factors influencing the rapid rise in C-Sin Bangladesh by considering an appropriate statistical model in line with the data structure. The study is based on the data from the 2017-2018 BDHS which is a nationally representative survey. BDHS is conducted periodically and 2017-2018 is the latest of all the BDHS conducted so far. Information used in the present study was collected from 5230 mothers who provided complete information about all the variables considered in the study. Among the Bangladeshi women, the rate of Caesarean sections (C-S) was reported to be 32.94% which is high in any international standard. Multilevel analysis suggests that the highest education level, current working status, wealth index, media exposure, number of decisions in which women participated, age at birth, BMI, birth order of the index child, number of ANC visits during the period of pregnancy, and childbirth weight have significant influence on whether mothers deliver babies through the C-S. In order to prevent needless caesarean deliveries and safeguard mothers from the consequences, Bangladesh urgently needs caesarean delivery policy guidelines. The study will help the policymaker in taking such initiatives. Dhaka Univ. J. Sci. 71(2): 117-126, 2023 (July)

  • Preparation and Characterization of Carbon Doped ZnO and Its Effectiveness
           as Photocatalyst under Visible Light

    • Authors: Mahbuba Zaman, Nasrin Akter, Md Ataur Rahman, Md Mufazzal Hossain
      Pages: 127 - 133
      Abstract: Carbon-doped ZnO (C-ZnO) was prepared and characterized by XRD, SEM, EDX and FT-IR spectroscopy. The substitution of oxygen in the lattice of ZnO by carbon greatly extends its optical sensitivity in the visible light due to the band gap’s shrinkage, which promotes the effectiveness of electron-hole separation. SEM images showed that the surface of C-ZnO catalyst is different from that of undoped ZnO. Analysis of the elements present in the sample was done by EDX which affirms that the prepared sample contains Zn, O and C atoms. The existence of ZnO as wurtzite is confirmed by XRD analysis exhibiting little deviation of the peak position due to the presence of carbon in substitutional sites. FT-IR analysis also supports these results. Under visible light irradiation, the prepared C-ZnO shows better photocatalytic efficiency on methylene blue (MB) than un-doped ZnO. The optimum photodegradation efficiency of MB has been observed when 2 percent C-doped ZnO obtained at 300˚C calcination temperature. Dhaka Univ. J. Sci. 71(2): 127-133, 2023 (July)

  • Robust Multiple Linear Backward EliminationRegression

    • Authors: Md Siddiqur Rahman, Sabina Sharmin
      Pages: 134 - 141
      Abstract: For building a linear prediction model, robust Backward Elimination (RBE) algorithm, which is computationally useful and scalable to high-dimensional large datasets, is introduced in this investigation. Backward Elimination (BE) can be stated in terms of sample correlations and simple RBE can be obtained by swapping out these correlations with their corresponding robust counterparts. The robust correlation for winsorized data was employed based on the adjusted winsorized correlation as a robust bivariate correlation. In another study, the Spearman rank correlation was employed as a robust bivariate correlation. However, the RBE has some drawbacks in the presence of multivariate outliers. In this article, the usage of FastMCD (Fast minimum covariance determinant)-based correlation is proposed in BE to reduce the influence of outlying data points. We call this proposed method BEmcd. A comprehensive simulation study was conducted to evaluate the performance of BEmcd with that of RBE based on winsorized correlation and Spearman rank correlation. Simulations and an application of actual data demonstrate the outstanding performance of BEmcd. Dhaka Univ. J. Sci. 71(2): 134-141, 2023 (July)

  • Simulation of Track and Landfall Process of Severe Cyclonic Storm Mora
           over the Bay of Bengal using WRF-ARW Model

    • Authors: Most Fatema Amin Akhi, Md Saddam Hossain, Md Shakil Hossain, Muhammad Abul Kalam Mallik
      Pages: 142 - 152
      Abstract: The simulations of Severe Cyclonic Storm (SCS) Mora (28-31 May 2017) generated over the Bay of Bengal (BoB) are performed in this study to analyze its features, landfall, and track using the Weather Research and Forecasting (WRF) model. WRF-ARW model has been used on a 10 km Horizontal Resolution (HR) domain for 96, 72, 48, and 24-hour lead time simulations. The model's performance is assessed by examining Mean Sea Level Pressure (MSLP), vertical distribution of velocity components, wind flow pattern, relative vorticity, vertical wind shear, relative humidity, latent heat flux at the surface, and track pattern. The simulated results are compared carefully to the observations from the Bangladesh Meteorological Department (BMD) and the India Meteorological Department (IMD). The findings are reasonably consistent with the observations. The simulated track is also reasonable even up to 72 hours in advance. Finally, the study's results suggest that the WRF model can be used as an effective tool in predicting TCs over the BoB. Dhaka Univ. J. Sci. 71(2): 142-152, 2023 (July)

  • A Systematic Review and Meta-analysis of Injecting Drug Use as a Risk
           Factor of HIV in Bangladesh

    • Authors: Swarna Chowdhury, Noor Jahan Akter, M Shafiqur Rahman, Priom Saha, Prianka Barman, Tasmin Akter Fahin, Swapnil Roy, Durjoy Dey, Md Mehedi Hassan, Tasnim Sultana Munmun, Samia Ashrafi, Maisha Maliha Rahman

      Abstract: HIV is a new, transpiring problem, especially, among injecting drug users (IDU) in Bangladesh. Although HIV prevalence in Bangladesh compared to the neighboring countries is still low, ongoing high-risk behaviors among injecting drug users could facilitate the more extensive transmission of HIV to the general population. This study aims to assess the relationship between HIV and injecting drug use. Through a systematic review, we included 19 studies that met the inclusion/exclusion criteria. Pooled prevalence, odds ratio, 95% CI, and measures of heterogeneity were calculated by the random-effects model. Publication bias was examined by funnel plots and Egger‘s test. We found the overall pooled prevalence was 3.65% (95% CI: 2.10-5.56%) which indicates that Bangladesh is on the brink of a concentrated epidemic. IDUs were 6.085 times more likely to be HIV-positive than non-IDUs (pooled OR: 6.085; 95% CI: 4.654-7.956). The pooled prevalence for males was reported to be 2.44% (95% CI: 1.51-3.57%), which was significantly higher than those for females with a pooled prevalence of 0.26% (95% CI: 0.00-1.19%). This meta-analysis revealed that injecting drug use is a significant risk factor for HIV in Bangladesh. Moreover, while the HIV prevalence in female IDUs was found to be very low, it was much higher in male IDUs. Dhaka Univ. J. Sci. 71(2): 160-168, 2023 (July)

  • Impact of COVID-19 and Russia-Ukraine war on the inflation rate of South
           and Southeast Asia

    • Authors: Tareq Rahman, Md Israt Rayhan
      Pages: 169 - 175
      Abstract: The financial value of money and the overall stability of an economy are significantly impacted by inflation. To investigate the effect of the COVID-19 pandemic and the Russia-Ukraine war on constant inflation rates in South and Southeast Asian countries between January 2019 and December 2022, this research utilizes monthly inflation rate data from the International Monetary Fund. Autoregressive integrated moving average modeling and prediction of inflation rates and the Bai-Perron method to estimate the structural breakdown of monthly inflation rate series are employed. Graphical methods and theoretical tests are used to diagnose the models, and the Chow test is utilized to assess structural breakdown in the monthly inflation rate series. The findings indicate that the Russia-Ukraine war since February 2022 has a more significant impact on the selected countries than the COVID-19 pandemic during January 2020 to December 2021.
