E-Waste-An Emerging Public Health Threat: Bangladesh Perspective

Electronic waste or e-waste is emerging as a major public health threat worldwide including Bangladesh because of rapid advances in technology leading to the generation of large amount of wastes and a lack of knowledge in handling of these wastes. The present review discusses the existing e-waste problem in Bangladesh, as a public health concern, and necessary recommendations to have effective e-waste management. This is a traditional review study. The burden of e-waste, regulations and its impact on health at the global and country level were identified using various search engines such as PubMed, Google Scholar, Scopus and ScienceDirect. Books, case studies, legislation documents, reports, original articles and other documents from international organizations and specific governmental agency websites were retrieved. Out of more than 100 research articles on e-waste and health impact in total, 45 original articles, reports, case studies and documents were used for this review. About 400,000 tonnes of electronic waste have been generated across the country in 2018 and that the amount grows by 20% every year. The generation of e-waste rate in Bangladesh has surpassed 72 million tons, which is a 33% increase over the previous decade. According to a study report by Bangladesh University of Engineering and Technology (BUET), e-waste volumes in Bangladesh will rise to 4,62 million tonnes by 2035. Harmful contents of e-waste mainly include lead, cadmium, mercury, chromium, copper, nickel, lithium, Beryllium long term exposure of which may cause health effects like damage to brain, kidney, liver, nervous systems, blood systems, endocrine system, reproductive system and produce stomach cramps, allergic dermatitis, asthma, bronchitis and also develop life threatening disease like cancer. The current review shows that the e-waste poses a serious public health threat leading to significant environmental and health risks. Most of the developing countries including Bangladesh were found to be lagging behind in the implementation of environmentally sound formal recycling processes. Hence, a better life cycle assessment model which have been successfully implemented in other developing countries should be introduced in Bangladesh. JOPSOM 2021; 41(1):41-48

Tarekul Islam Institute of Water and Flood Management, Bangladesh University of Engineering and Technology (BUET), Dhaka 1000, Bangladesh *Corresponding author: saiful3@gmail.com ABSTRACT: Bangladesh regularly faces various extreme events (floods, droughts, cyclones, and heat waves), but there is a knowledge gap between average climate and climate extremes over the country. The purpose of this study is to quantify the trends over Bangladesh for the period 1981-2010 using the extreme temperature and precipitation indices developed by the CCl/WCRP/JCOMM Expert Team on Climate Change Detection and Indices. We used precipitation and temperature data from 26 meteorological stations, calculated trends in the indices using Sen’s slope estimator, and tested significance using the non-parametric Mann-Kendall trend test. For the temperature indices, we found an overall increasing warming trend. Average annual maximum and minimum temperatures increased by 0.3 and 0.4°C decade-1 respectively. A faster rise of both maximum and minimum temperature was found compared with previous studies. The frequency of warm days increased by 12 days decade-1. The frequency of warm (cold) nights increased (decreased) by 7 (11) days decade-1. The overall warming was accelerated at the end of the climatic period (2001-2010). Precipitation indices showed an overall decreasing trend, in contrast to other studies in this region. Trends in consecutive dry days (CDD) indicated a drying tendency at a rate of 10 days decade-1. A decreasing rate of about 84 mm decade-1 was observed in annual average total precipitation. Except for CDD, most of the precipitation trends were statistically not significant and spatially incoherent. Statistically significant change was observed in extreme temperature events, with a strong and consistent spatial pattern. Our results pave the way for further investigations into future changes using results from climate simulations.

An Analysis of the Most Accident Prone Regions within the Dhaka Metropolitan Region Using Clustering

Most of the world's developed countries have decreased the unusual deaths like traffic accidents of their citizens by taking efficient steps. In Bangladesh, injuries because of road accidents have become a regular incident. The highly-populated cities in Bangladesh are still having such incidents daily. As the number of vehicles is increasing and most of the drivers are not willing to follow the traffic rules, injuries due to traffic accidents are not going down at all. Among all those big cities in Bangladesh, Dhaka City has the highest amount of road accidents. So, in this paper we focus on the most hazardous regions in Dhaka Metropolitan area. We have collected the accident related data from Accident Research Institute (ARI) at Bangladesh University of Engineering and Technology (BUET) that is located in the city of Dhaka. In our paper, we have used the fuzzy C-means clustering, expectation maximisation, hierarchical agglomerative clustering and K-means clustering to identify the regions where traffic incidents occurs the most in Dhaka Metropolitan area. The missing values for some attributes in the dataset are overwritten by the mean/mode of that attribute itself.

Rhetorical Structure of Introduction in Applied Linguistics Research Articles

ABSTRACT : The RA ( Research Article) is considered to be the main channel of knowledge production . H owever, for student writers and novice scholars writing , RA is a challenging task. It is partly because of lack of exposure to and awareness of the rhetorical structure of RAs ( Research Article s) in the intended discipline. The objective of this study is to identify the rhetorical moves of RAs in applied linguistics and explaining their communicative functions that can be used for pedagogic purposes for novice scholars in this discipline. Analyses of moves and their constituent steps together with their frequency count would help suggest obligatory and optional moves in the Introduction section. Also a nalysis of move structural patterns , which would enable to draw possible move sequencing is within the purview of this study. A corpus of 20 empirical RAs of leading and representative 4 journals in applied linguistics have been analyzed following J.M. Swales (1990 and 2004) move analysis of Introduction sections of empirical RAs. Results were obtained through software coding of moves of these 20 RAs , and through qualitative analysis of communicative functions of moves and steps. From the frequency count of moves and steps , it is found that some moves and their constituent steps are obligatory , while others are optional. Findings show they both conform to and depart from J.M. Swales ’ CARS ( Create-a-Research-Space) model in 1990 and 2004 . The findings of the study will facilitate better understanding of RAs in applied linguistics for novice scholars and contribute to these scholars’ efforts to publish their research in this field.

Performance of an Electricity-Generating Cooking Stove with Pressurized Kerosene Burner

A clean-burning cooking stove that also generates electricity (The Score-Stove™) was modified to enable evaluations to take place in 3 regions of Bangladesh. Using the principle of thermo-acoustics to generate electricity it can supply power for applications such as - LED lighting, mobile phone charging and radios particularly in rural areas without grid electricity. After assessing the needs of the rural communities through a survey, tea-stalls and small restaurants owners were identified as people with the most potential of using the Stove in Bangladesh. The Bangladesh University of Engineering and Technology ((BUET) modified a Score-Stove to use both wood and a pressurised kerosene burner of a design that is widely used for cooking in rural areas of Bangladesh. The design was adapted to meet performance needs such as: heating rate, cooking efficiency, energy distribution, electric power generation, exhaust emissions and time taken to boil water using standardised water boiling tests. Performance was also compared with conventional (non-electrically generating) stoves that use a pressurised kerosene burner. A stove suitable to be demonstrated was developed to obtain feedback from some end-users for evaluation. Effects of the technical changes to the stove required for field trials and laboratory experimental results are presented. Technical deficiencies are documented and recommendations for improvements and future research in order to obtain wider end-user acceptance are made.

Performance of a Score-Stove with a Kerosene Burner and the Effect of Pressurization of the Working Fluid

Score-StoveTM a clean-burning cooking stove that also generates electricity was tested using a pressurized kerosene burner. The Score-Stove works on the principle of thermo-acoustics to gen- erate small-scale electricity. The device having hot-end, cold-end and regenerator acts in a way similar to a stirling cycle generating acoustic power, which is then converted to electricity using a linear actuator. It can supply small power for applications such as LED lighting, mobile phone charging and radios particularly in rural areas without grid electricity as well as improving house- hold air pollution. After assessing the needs of the rural communities through a survey, tea-stalls and small restaurants owners were identified as clients with the most potential of using the stove in Bangladesh. Bangladesh University of Engineering and Technology ((BUET) modified a Score- Stove to use both wood and a pressurized kerosene burner of a design that is widely used for cooking in rural areas of Bangladesh. The design was adapted to meet performance needs such as: heating rate, cooking efficiency, energy distribution, electric power generation, exhaust emissions and time taken to boil water using standardized water boiling tests. Performance was also compared with conventional (non-electrically generating) stoves that use a pressurized kerosene burn- er. The Score-Stove performance was then evaluated while increasing the pressure of the sealed working fluid (air in this case) from atmospheric to about 1.4 bar. The pressurization was found to almost double the power generation. An arrangement for utilizing cooling water waste heat was also devised in order to improve the thermal performance of the stove by 18%. Technical deficiencies are documented and recommendations for improvements and future research in order to obtain wider end-user acceptance are made.

Experimental Study on the Effectiveness of Emerged and Submerged Coastal Bio-Shield in Storm Surge Protection

Surges and waves induced by cyclones and other severe storms can cause devastating damage of property and loss of life in coastal areas of Bangladesh. Bio-shield in wetlands can reduce the energy of storm surges and cyclones. To study the effectiveness of emerged and submerged coastal bio-shield in storm surge protection, a laboratory experiment was carried out in a 22 m long, 0.75 m wide and 0.75 m deep wave flume in the Hydraulics and River Engineering Laboratory of Bangladesh University of Engineering and Technology (BUET). Experiments were carried out for investigating the performance of the bio-shields in submerged as well as emerged conditions. Bio-shields were represented by cylindrical bamboo sticks as rigid bio-shield and polyethylene as flexible bio-shield whose diameter was 6 mm. There were a total of 51 experimental runs covering 3 different wave periods of 1.6, 1.8 and 2.0 seconds. Time-series of water surface elevations for vegetated (with bio-shield) and non-vegetated (without bio-shield condition) were compared to identify the influence of bio-shield on wave height reduction. It is found for emerged and submerged conditions of bio-shield that the maximum wave height reductions are 71% and 52% at a location which is 3.5 m away from the embankment for wave periods of 2.0 sec at bio-shield spacing of 50 mm c/c and 25 mm c/c respectively. These reductions of wave heights occur when bio-shield of 2 m width (1 m Rigid + 1 m Flexible) are placed at 4 m distance from the embankment. Hence, the most effective position for maximum wave height reduction by both emerged and submerged bio-shield of 2 m width is 4 m distance from the embankment. It is anticipated that these results will find broad application in coastal management and planning for areas with existing coastal bio-shield as well for bio-shield restoration and establishment efforts.

Determinants of Tertiary Education Quality in Bangladesh

The concept of quality in tertiary education, which entails creating and advancing knowledge for developing enlightened citizens those can contribute to the development of a country is multifaceted in nature. It can only be ensured by activities and functions of quality control mechanism which are carried out by the graduates in their university academic periods. But, in case of Bangladesh, there is no specific quality assurance mechanism effective rather different are used with respect to public universities, private universities, and tertiary level college. And, most of the cases there is no provision of external review of quality. As a result measuring tertiary education quality as a whole most of the cases cannot be possible. But, irrespective of the institution there are some common issues or determinants which significantly affect the tertiary education quality. And, the objectives of this paper are to identify those determinants and evaluate their relative importance with respective to ensuring tertiary education quality. To perform the objectives primary data have been collected through formal questionnaire from 167 respondents including teachers and students of Bangladesh University of Engineering and Technology (BUET) by random sampling method. Primarily, this research takes into account 20 determinants i.e. entry requirements of the students, sound teaching ability impartiality in evaluation, sincerity of teacher, accountability of teacher, communication capability of teacher, infrastructural facilities, research opportunities, seminar and workshops, teaches polities, student politics, class size, session jam, reputation of the institution, program curricula, practical implication of knowledge, career potentials, medium of instructions, extracurricular activities, and cost of education, as effective in ensuring tertiary education quality. From the analysis of respondents’ data, it is found that sincerity of teacher is the most important determinant in ensuring tertiary education quality while communication capability of the teacher is of second choice to the respondents. The determinants which are of lowest value to respondents are teachers politics followed by student politics also. After the analysis of data this paper makes an overview on current status of these determinants in Bangladesh. Finally, this paper offers some recommendations regarding the enhancement of tertiary education quality in Bangladesh for making the graduates more competent in facing the challenges of 21st century.

Rating Curve Pattern in a Compound Meandering Channel Flow

Most of the river flow in the world can be characterized as compound meandering channel in which the discharge distributions are very complex. Engineers, planners and researchers are highly interested in predicting accurately as well as reliably the quantitative estimates of discharge in a compound meandering channel. A laboratory experiment has been performed in a compound meandering channel with symmetric cross-sections having floodplain width ratio of 1.00, 1.67, 2.33, 3.00 and depth ratio of 0.20, 0.30, 0.35, 0.40 using the large-scale open air facility in the Department of Water Resources Engineering, Bangladesh University of Engineering and Technology (BUET), Dhaka, Bangladesh. Point velocity data have been collected using an ADV (Acoustic Doppler Velocity meter) for different depth and width ratio at different locations of a compound meandering channel. Cross-sectional discharge is computed by area velocity method from the observation of velocity profile. The laboratory experiment shows that the rating curve pattern in a compound meandering channel follows the straight curve up to in bank flow and in the out bank flow it is in curvature nature.

An Experimental Study of Shear Stress Distribution in a Compound Meandering Channel

Naturally river flow can be characterized as compound meandering channel in which the shear stress characteristics are quite intricate. Reliable investigation of shear stress distribution in a compound meandering channel is essential in solving a variety of river hydraulics and engineering problems, designing stable channels and bank protection, understanding the mechanism of sediment transport. A laboratory experiment has been conducted in a compound meandering channel with symmetric cross-sections having floodplain width ratio of 1, 1.67, 2.33, 3 and depth ratio of 0.20, 0.30, 0.35, 0.40 using the large-scale open air facility in the Department of Water Resources Engineering, Bangladesh University of Engineering and Technology (BUET), Dhaka, Bangladesh. Point velocity data have been collected using an ADV (Acoustic Doppler Velocity Meter) for different depth and width ratio at different locations of a compound meandering channel. Shear stress is calculated from the Prandtl-Von Karman Universal Velocity Distribution Law. The laboratory experimental investigation reveals that shear stress increases with the increase of depth and width ratio and low magnitude of boundary shear is observed in the outer bend as compare to the inner bend in a compound meandering channel.

An Experimental Study of Longitudinal Velocity Distribution at Cross-over and Bend Section of a Compound Meandering Channel

Generally, river flow can be schematized as compound meandering channel in which the longitudinal velocity distributions in the crossover and bend section are completely different and quite intricate. Engineers, Planners and Researchers are highly interested in predicting accurately as well as estimating quantitatively and reliably the longitudinal velocity distribution in a compound meandering channel. A laboratory experiment has been conducted in a compound meandering channel with symmetric cross-sections having floodplain width ratios (B/b) of 1.00, 1.67, 2.33, 3.00 and depth ratios (H-h)/h of 0.20, 0.30, 0.35, 0.40 using the large-scale open air facility in the Department of Water Resources Engineering, Bangladesh University of Engineering and Technology (BUET), Dhaka. Point velocity data have been collected using an ADV (Acoustic Doppler Velocity Meter) for different depth and width ratio at five different locations of a compound meandering channel. The traditional power law represents a vertical distribution of longitudinal velocity in open channel with maximum value at free surface and with zero at the channel bed. But the velocity distribution in the type of natural or laboratory compound meandering channel does not follow such velocity distribution. The longitudinal velocity distribution of a compound meandering channel shows two characteristics for all cases and depth ratios. In the bend section, velocity increases in the inner bend (convex) and decreases in the outer bend (concave). Similar nature is observed in the floodplain boundary for all cases and depth ratios. In the crossover of a compound meandering channel, velocity increases towards the mid-section and decreases in the boundary of the channel.

Problem-Based e-Learning and Evaluation System forDatabase Design and Programming in SQL

 Abstract—Problem-based e-Learning (PBeL) can be a highly successful model for the teaching and learning of Database, one of the core courses of Computer Science and Engineering in undergraduate level. There are very few e-Learning systems found to support the learning of the different components of Database course. Existing systems provide only the partial solution of extensive learning of this course and also do not support the automatic evaluation of student performance. The main components of database practical course are: database design, SQL, PL/SQL and implementation of database projects. In this research, we have developed a system: SQL Learning and Evaluation System (SQL-LES) for effective teaching and learning of all of the above components of the practical parts of the database course. We have developed a question bank covering all areas of SQL questions and answers. The question bank can be used for both learning and automatic evaluation of student's performance by creating test sets and assigning the test sets to the individual students. The system can effectively be used for the teaching, learning and evaluation of database design, PL/SQL and database projects as well. SQL-LES has been applied in teaching, learning and evaluation of database laboratory course in undergraduate level of the Department of Computer Science and Engineering (CSE), Bangladesh University of Engineering and Technology (BUET) in several years and found to be very effective in classroom environment.

Performance of Coastal Structures during Cyclone Sidr

On November 15, 2007, Bangladesh was hit by the category 4 storm Severe Cyclonic Storm Sidr. At least 3,447 deaths were reported in coastal areas of Bangladesh, mainly owing to the storm surge, which was >5  m. A study team of several faculty members of Bangladesh University of Engineering and Technology (BUET) was formed to visit areas affected by Sidr, two months after the storm. It was found that cyclone shelter capacities were inadequate for the population of the service area. Without shelters, many livestock animals died during the disaster. Many people neglected cyclone warnings, which resulted in many deaths. To improve cyclone shelter performance, this study makes many recommendations, including building more cyclone shelters, providing shelters for livestock, and improvement of warning systems.

The quality of the water sources used in Bangladesh is at high risk, especially in the capital city of Dhaka, due to increased pollution resulting from unlimited migration of rural people. Consequently, the existing groundwater-based water supply system is not adequate to fulfil the water demand of the mega-city Dhaka. To alleviate the city's present severe water crisis, the question has been asked as to why the Dhaka Water Supply and Sewerage Authority (DWASA) is not using the rivers around Dhaka as a source of water. In this context, DWASA is seriously considering two options: (i) introduction of a separate water supply system for domestic purposes other than drinking water by pumping available river water around the city; and (ii) installation of a small-scale treatment plant for water supply using river water around the city as a source of raw water. Implementation of either of these options will require a study on the quality of the water sources, and development of appropriate cost-effective treatment methods. A study has been conducted at the Bangladesh University of Engineering and Technology (BUET) to evaluate the important physical, chemical, and biological water quality parameters of the five rivers around Dhaka City. Test results indicate that the water of all rivers around Dhaka City is highly polluted during the dry season, except for water of the River Sitalakhya. The important water quality parameters in the dry and wet seasons, when compared with earlier values, indicate that the degree of pollution of these rivers is gradually increasing with time. This paper focuses on the study and analysis of important water quality parameters of river waters around Dhaka City.

Traffic pollution inventories and modeling in metropolitan Dhaka, Bangladesh

Several monitoring and surveys on ambient concentration of oxides of nitrogen (NO x ), lead (Pb), particulate matter (PM), carbon monoxide (CO) and black smoke have been carried out by the author, Bangladesh Atomic Energy Commission (BAEC), Department of Civil Engineering, Bangladesh University of Engineering and Technology (BUET), and Department of Environment (DOE), Bangladesh Government at different street intersections of metropolitan Dhaka. In addition, all traffic pollutant concentrations at 82 street intersections were estimated using the Gaussian Plume Model. The surveys and the analysis were undertaken primarily to provide an independent check on the pollutant concentration and to determine if there is any violation of the international compliance. The study covers, for the first time in its type, wide areas of road intersections and surveyed concentration of oxides of nitrogen. It has been observed that the concentration of NO x , black smoke, lead, and PM violate both the national and international standards in metropolitan Dhaka. In addition, the concentration of CO is found relatively higher during the noon buildups.

Linkage and academic exchange experiences at Bangladesh University of Engineering and Technology

Linkage and cooperation with other universities in the domain of education, research and training is viewed as one of the important activities in many universities. Since its creation in 1962, Bangladesh University of Engineering and Technology (BUET) has maintained contacts with foreign universities in the region and other parts of the world through academic linkage and cooperation projects. This is necessary and has been found to be useful in keeping abreast of changes and innovations in research, teaching, as well as in program and staff development. The purpose of academic and research linkages is to encourage and promote transfer of knowledge and expertise which is often facilitated through two way exchange and cooperative visits by faculty and students of participating universities. Visits are generally designed for the purpose of field experience, cooperative research, and teaching. In order to keep pace with the changing and ever expanding frontier of knowledge, the need for international linkages and exchanges is receiving increased interest. The goal of these exchange and linkage agreements is a stable and self financed institutional relationship promoting productive, cooperative research and curriculum development. Donor agencies, generally identified jointly by participating universities, provide funds for equipment, reference materials, and exchange fellowships. Each participating university provides counterpart funds by absorbing substantial costs of salaries, benefits, overheads, and administration.
