A cross-sectional study of 300 children-caregiver dyads was conducted in an urban slum of Bangladesh. Data were collected via a structured questionnaire with accompanying anthropometric assessments of children administered by research staff. Multiple logistic regression was employed to identify associated factors of health care seeking behaviors. Only 44.7% and 13.0% of respondents sought care for childhood infectious diseases and malnutrition, respectively. Being a male child, 2–5 years old, having ≤5 family members, monthly family income >125$, and living in close proximity to a health facility were found to be potential determinants of health care seeking behavior for childhood infectious diseases. Mother/caregivers with poor nutritional information knowledge and who had a child 2–...

Different kinds of fibers can be used to stabilize sandy soil. In this research by using jute fiber as admixture is to improve the engineering properties of sandy soil. The most efficient fiber reinforcement results were obtained by adding jute fiber with content of 0.5%, 1%, 1.5% and 2% as admixture. Sieve analysis, specific gravity test, direct shear test and proctor compaction test were performed. In order to determine and compare both the untreated and treated soils, a specific gravity test was conducted. Particle size distribution of the soil sample was performed by the sieve analysis. In direct shear test for untreated and treated sandy soil the angle of frictions was determined. The angle of frictions are gradually increasing after using 0.5%, 1%, 1.5% and 2% jute fibers as admixture which means stability and shear strength properties of soil are increasing. After using 2% jute fiber as admixture in direct shear test better strength was found analytically. From proctor compaction test, maximum dry density and optimum water content were determined for different proportionate (jute fiber percentage same as before) of jute fiber as admixture. As for using 1% jute fiber as admixture, maximum dry density was obtained which means it increases strength and gives better volume stability

Typically, the ovaries are entirely normal, although one or both also may be undescended, hypoplastic, or associated with an inguinal hernia. Affected patients often also have urologic anomalies (15-40) % (unilateral renal agenesis, ectopic or horseshoe kidney, and duplication of the collecting systems) and skeletal malformations (5-10) %, (e.g., hemiverterbrae and scoliosis, or the Klippel-Feil syndrome). The cause is unknown, although some cases are associated with chromosomal translocations or occur in familial aggregates, suggesting a genetic basis. Logically, müllerian agenesis might be attributed to an activating mutation in the gene encoding AMH or its receptor, causing excess AMH activity, but none have been identified. Aim: The aim of this study was to analyze and present rare cases of partial...

Photovoltaic (PV) panels are widely popular as a vital source of renewable energy all over the world as well as in Bangladesh. However, besides solar irradiance, the panel output is greatly affected by some of the weather parameters like temperature, humidity, wind, etc. Reliable forecasting of PV panel output is essential for capacity planning in advance to efficiently manage the energy distribution. This paper presents a method to forecast the PV panel output energy using a machine learning model, known as the Prophet Model used for a univariate time series forecasting. For this study, the PV panel generated data are collected from an outdoor experimental set-up throughout the full winter season in Bangladesh. Based on the data, forecasting of one-day-ahead PV panel short circuit current is done, and then the estimation of PV panel output energy is made. The results show the proposed forecasting method to be quite encouraging and reliable one while providing a higher coefficient of determination value with an average 0.9772 for one-day-ahead PV panel output energy forecasting.

Conscious dreams are the result of weird mathematical manipulation of our daily life. We see a dream that, one day the education system of Bangladesh will be on the right track. On 16th December 1971 Bangladesh after getting independent from suppression, Bangabandhu Sheikh Mujibur Rahman, the father of the Nation had a dream to build a successful nation, namely Shonar Bangla. For doing the same, it was necessary to build an educated nation not only by producing Dr., Engineers, and Teachers but also by producing effective practical knowledgeable human resources. To formulate an effective education policy, different government formed different commission but, due to some invisible reason, no commission got materialized. In this current conceptual paper, we will be focusing on Bangladeshi educational institute and, education p...

The effect is more pronounced during the dry season when the environment is dustier. In this work, an investigation is conducted to understand how dust particles can affect the performance of the PV panels installed on the rooftop of a high-rise building during the dry season. Two monocrystalline 20W PV panels, deployed on the rooftop of a seven-story building in Gabtoli, Dhaka, Bangladesh, have been used for this purpose. Measurements are carried out over four months, starting from 1st November 2019 to 29th February 2020, during which the weather remains mostly cold, dry, and dusty. It has been observed that dust accumulation monthly decreases the short-circuit current from a minimum of 5.52% to a maximum of 22.31% during this period. The maximum reduction in the daily output energy during this period is observed to be about 35%. The effect of dust has been observed to be most pronounced during December 2019, which shows a decrease of over 22% in total monthly energy output in the dusty panel compared to that of the clean panel.

In addition, the study also aimed to identify the photodegradation of landfill leachate under natural sunlight. The leachate pH was slightly alkaline (7.87-8.07) with a minimum level of dissolved oxygen, and low BOD 5 /COD ratio that are indicators of the matured methanogenic phase. Ca, Fe, Br, Rb, Cu was present in a considerable amount. A trace amount of Sr, Co, As, Pb, Cr was found in the leachate sample. Fourier Transform-infrared (FTIR) spectra of all three samples had five major peak regions notably at 3440-3450 cm À1 (O-H groups of water), 1638 cm À1 (C¼O Amide I, carboxylates C¼C, aromatic ring modes, or alkenes), 1385-1390 cm À1 (deformation of the C-H bond in CH 2 and CH 3 , or the asymmetric stretching of COO), 1115 cm À1 (stretching of the CO bond in phenol ethers and phenols) and 605 cm À1 (S-O bends of sulfates). In addition to the appearance of new peak, peak shifting on the 2 nd-day and 5 th-day phototreatment are in compliance with the 34% TOC reduction. From analyzing three-dimensional excitation/emission (3D-EEM) spectra of the raw sample pyrene-like or humic-like peak A (Ex 255/Em 465), soil fulvic-like peak M p (Ex 315/Em 450), and humic-like peak C (Ex 370/Em 455) was found indicating more humified characteristics of the mature landfill site. From 1-hour to 6-hours phototreatment, all three substances slightly lost fluorescence intensity. From the 2 nd day to the 5 th day of photo-treatment, two unknown photo-product was identified within Ex 210/Em 457 and Ex 205/Em 408 at peak A region. Fluorescence intensity lost was 65% for peak A and 44% for peak C. Soil fulvic-like peak M p was absent on the 5 th day of photo-treatment.

In this paper, we mainly focus on the transmission of ebola virus disease, estimate the burden of the disease and the persistent nature by finding the basic reproduction number, and analyze the comprehensive steps to control the virulent disease. We have considered three mostly affected countries, Guinea, Liberia, and Sierra Leone respectively and collected data from various sources are used to surmise the present and future nature of the disease. Being the poorest country in the world like Guinea, Liberia, and Sierra Leone, they do not have efficient policies to fight against such kind of endemic and they have been unable to control the spread of the disease. We have found some real facts that increase the chances to be infected by this virulent disease. Since the reproduction number 0 R is still above unity and if we do not take precautionary steps and work accordingly then the disease will definitely exist in the community and the burden of the disease would increase continuously.

It is believed to have an excessive occurrence in lives of women in South Asia. The objective of this study is to describe the prevalence, risk factors and consequences of IPV in Bangladesh. Methods: A scoping review was carried out based on the past 12 years of posted and gray literature about IPV in Bangladesh using Arksey and O’Malley’s framework. Only the literature addressing abuses or violence in households or outside including physical, sexual or mental violence on the married woman in Bangladesh were taken into consideration for the study. Results: The overall prevalence of IPV in Bangladesh, the latest reviews of rates ranging from 15.5-82.7%.Most of the IPV in Bangladesh was based totally on the experience of legally married women. The main risk factors of IPV in Bangladesh were women being younger,...

Visual disturbances in (pre)eclampsia seem to be frequent phenomena. Therefore, the obstetrician/gynecologist may encounter women with serious, and sometimes debilitating, pathology of the visual pathways. Methods: This is a cross sectional observational study was conducted over a period of 12 months (January 2016-December 2016) at Dhaka Medical College Hospital, Dhaka, Bangladesh. Patients with severe preeclampsia and eclampsia were included in the study. The association was measured with Chi-squared test and p value of 0.05 was treated as significant. Results: During this 12-month period, 100 patients with severe preeclampsia and eclampsia were studied the mean age was 26.4 ± 5.5 years. The association between retinal changes and different variables was statistically significant positive association between the presence of retinal changes and blood pressure (P=...

In the study area, average pond size was 0.83 ha (2-7 feet depth) and 80% of the ponds were characterized with loamy soil. Ground water was the main source for 70% of the ponds where about 90% of the fish farmers were engaged in polyculture of carp species. Majority of fish farmers were in the age group of 41-50 years with fish farming experience of 16 years (44%). Activities of DoF were minimum regarding fish farming of the fish farmers. In the present study, 80% of the respondents were related to fish culture as their principal occupation and majority of the fish farmers (50%) have the annual income of BDT 51,000 to 100,000. 30% of the respondents were educated up to secondary le...

In this paper, we mainly focus on the transmission of ebola virus disease, estimate the burden of the disease and the persistent nature by finding the basic reproduction number, and analyze the comprehensive steps to control the virulent disease. We have considered three mostly affected countries, Guinea, Liberia, and Sierra Leone respectively and collected data from various sources are used to surmise the present and future nature of the disease. Being the poorest country in the world like Guinea, Liberia, and Sierra Leone, they do not have efficient policies to fight against such kind of endemic and they have been unable to control the spread of the disease. We have found some real facts that increase the chances to be infected by this virulent disease. Since the reproduction number 0 R is still above unity and if we do not take precautionary steps and work accordingly then the disease will definitely exist in the community and the burden of the disease would increase continuously.

When the diamond films were implanted after pretreatment or in the course of diamond growth and were grown by microwave plasma chemical vapor deposition, some modified structural characteristics and improved electrical characteristics were obtained. Secondary ion mass spectrometry analyses of some diamond films led to the conclusion that phosphorus ions and defects in the Si-diamond interface play an important role in the enhancement of field emission from diamond films.
