Natural Gas Driven Vehicles Safety and Regulatory Regime - Challenges in Bangladesh

Natural gas driven vehicles (NGV) is common in Bangladesh first introduced around 1995. Be that as it may, situation has changed because of minimal effort of CNG as fuel. The legislature additionally empowered the change of private vehicles by making a few strategy activities as Bangladesh has natural gas reserve, cost economy, low emission. Now passenger automobile like car, bus, and even agricultural vehicles are utilizing CNG as fuel. Faulty cylinders or other CNG-related kits in NGV not only endanger the lives of the passengers of the vehicles, but also of others somehow remaining close to the accident spots. The safety aspect of CNG runs vehicles are beyond regular and strict monitoring, even out of consideration. The objective of this paper is to find out the present scenario of the NGV of Bangladesh and safety perspective in compare to the CNG safety act of Bangladesh. For this purpose, other CNG safety standard of first world country along with exporter country is under consideration. This paper reviews the options available to policy makers in their efforts to reduce the causalities associated with NGV transport. It provides a summary of the categories of negative impacts targeted together with the specific policy initiatives available. The actions for regulation taken by policy makers and foregoing challenges are underlined. To fight against the challenges a framework has proposed

Design improvement of a laboratory prototype for efficiency evaluation of solar thermal water heating system using phase change material (PCMs)

Thermal energy in the solar thermal energy storage system cannot be stored for a long time during the evening hours as well as days that have minimal sunlight due to heat transfer to the surrounding atmosphere. PCMs are being implemented into these storage systems to enhance the thermal storage capacity of solar energy. PCMs based latent heat storage technique can extend thermal energy storage over long periods due to its ability to store energy. Several different types of PCMs with various chemical compounds and melting temperatures can suit various thermal storage applications in real life. However, the concept of combining these PCMs types with different ratios is an area within this field that has not yet been investigated as it is time-consuming and a matter of numerous combinations and trials. A model solar thermal energy storage system with the flexibility to test different PCM’s blends can omit the problem. This research work intended to propose a design as testing apparatus that can successfully operate and investigate the different PCM’s blends to find the optimum ratios for a highly efficient solar thermal water heating system. An appropriate laboratory-sized prototype design has described that can replicate the functions of a solar thermal water heating system. The necessary assumptions and mathematical relations are also presented for the proposed design

Analysis of conveyor drive power requirements in the mining industry

This article presents the analysis of conveyor drive power requirements for three typical mining conveyors. One of the conveyors was found not to be able to start when fully loaded. The analysis indicates that two of the conveyors are adequately powered while one is underpowered. This was found to be primarily the result of the maximum tonnage of the two adequately powered conveyors being 1500 tonnes per hour (TPH) while the inadequately powered conveyor was classed with a maximum tonnage of 1800 TPH. It is recommended that the current draw for each motor when fully loaded be measured. This will be compared to the design. Further analysis was done to allow 2000 TPH on all conveyors. The required upgraded drive size is presented. This article does not address the structural adequacy of the supporting structure. Rather, only the capabilities of the conveyor belt and drives to transport the required TPH

REPORTING DISCLOSURE LEVELS AND COMPLIANCE WITH BB, AAOIFI, B/IFRS AND SEC OF ISLAMIC FINANCIAL INSTITUTIONS IN BANGLADESH

Compliance with financial reporting guidelines/standards promulgated by Regulatory Bodies has become a crucial issue of the day after a series of corporate debacles over a few years. Regulators, professional bodies and researchers throughout the world have expressed their concern about the need for improved accounting pronouncements and compliance for providing better information than previously required for the preparation and presentation of corporate financial reporting. The present study primarily focuses on the reporting disclosure levels and compliance with Bangladesh Bank (BB) Guidelines, Accounting and Auditing Organization for Islamic Financial Institutions (AAOIFI) Accounting Standard, Bangladesh/International Financial Reporting Standard (B/IFRS) and Securities and Exchange Commission (SEC) Rules of Islamic Financial Institutions in Bangladesh. Annual reports of (08) eight Islamic banks in Bangladesh have been examined for the year ending 2015. The results showed that the Islamic banks significantly followed the selected accounting guidelines/standards under review and did bring remarkable changes in the financial reporting practices made by the Islamic banks in Bangladesh. The study attempted to examine empirically the levels of disclosure in corporate annual reports of Islamic banks in Bangladesh. The study recommended increasing the level of compliance to make their financial reports more informative. The study also tries to ascertain the regulatory necessary requirements in preparing the financial statements of banks under Islamic shariah and tries to display the compliance status of these banks with legislations. The average compliance rate is 93.28% for BB guidelines, 46.54% for AAOIFI Accounting Standard, 48.50% for B/IFRS and 51.99% for SEC rules considering all required aspects of financial reports. Compiling all of the requirements regarding financial reports of regulatory bodies will be helpful for banks to make financial reports convenient

A Precise Evolutionary Approach to Solve Multivariable Functional Optimization

Genetic Algorithm (GA) is a stochastic search andoptimization method imitating the metaphor of naturalbiological evolution. GA manages population of solutionsinstead of a single solution to find an optimal solution to agiven problem. Although GA draws attention for functionaloptimization, it may search same point again due to itsprobabilistic operations that hinder its performance. In thisstudy, we make a novel approach of standard GeneticAlgorithm (sGA) to achieve better performance. Themodification of sGA is investigated in selection andrecombination stages and proposed Precise Genetic Algorithm(PGA). PGA searches the target space efficiently and it showsseveral potential advantages over the conventional GA whentested for solving functions having multiple independentvariables

Medication wastage and its impact on environment: evidence from Malaysia

The purpose of this study is to investigate the critical factors that have impact on environment causes of unused medication. The current study is a descriptive cross-sectional audit involving with patients based on a structured questionnaire format with answer sets. The data is analyzed using partial least square method. The results revealed that excess supplied, expired medicine, changed treatment and side effects have a significant impact on unused medication. In addition, overall unused medication has a significant relationship with environmental effect. In contrast, although excess supplied and side effects have not significant impact on environmental effect, but expired medicine and changed treatment have a significant impact on environmental effect. This survey results suggested; there are few factors which increased the volume of leftover medicine and it has led to an enhanced international awareness of the potential detrimental effects on the environment. More exertion is necessary to raise awareness of people in general as an initial step in promoting behavioral change in connection to medication wastage

Fetomaternal outcome in patients with eclampsia: study in a territory care hospital in Bangladesh

Background: Eclampsia, a severe complication of preeclampsia, poses significant risks to both the mother and the fetus. Understanding the specific factors influencing these outcomes in the context of Bangladesh is crucial for improving maternal and neonatal healthcare in the region. Methods: A retrospective cohort study was conducted at department of gynaecology and obstetrics, Jashore Medical College Hospital, Jashore, Bangladesh reviewing medical records of 155 patients diagnosed with eclampsia over a January 2020 to December 2020. Data on maternal age, gestational age, clinical presentation, management strategies, and fetal outcomes were collected and analyzed. Results: Preliminary findings suggest that maternal age, gestational age at onset, and timely interventions play crucial roles in determining the fetomaternal outcomes in eclampsia cases. Maternal mortality rates, neonatal morbidity, and mortality rates were assessed in relation to these factors. Additionally, the study investigates the impact of various management approaches, including antihypertensive medications, and magnesium sulfate therapy on these outcomes. Conclusions: Eclampsia continues to pose significant risks to both mothers and infants in Bangladesh. Inadequate antenatal care appears to contribute to the severity of cases. The high rate of emergency cesarean sections underscores the need for vigilant monitoring of high-risk pregnancies. Efforts to improve antenatal care utilization and implement timely interventions are crucial to mitigate the adverse fetomaternal outcomes associated with eclampsia in this setting. Further prospective studies are warranted to explore preventive strategies and optimize management protocols for better outcomes
