Corporate Social Responsibility (CSR) is gaining fast global acceptance as a standard to assume environmentally sustainable and socially equitable business practices. Sustainable development, on the other, is emerged as a new development paradigm to meet the needs of the present without compromising the ability of future generations to meet their own needs. The study aims at investigating CSR activities in the way of sustainable development of Bangladesh. In doing so, extensive desk study and literature survey were done. Although internationally CSR is being practiced in the way of sustainable development widely, Bangladesh is still lagging behind. The difference between the world standard and the practice in Bangladesh shows the lacking here and the scope for further development. There are many challenges to implement CSR in Bangladesh. But its future and prospects are good. Companies can contribute to social and environmental objectives, through integrating CSR as a strategic investment into their core business strategy, management instruments and operations leading to the sustainable development of Bangladesh.

The main aim of the study is to evaluate and compare the performance of public and private banks in Bangladesh. Performance measured in terms of bank’s profitability always remains the focal point of all the banking activities. Data collected from publically and privately owned and managed banks in Bangladesh revealed that profitability of both banks was not satisfactory though private sector bank was more profitable than public sector bank during the period of this study.

Physical rehabilitation medicine started in Bangladesh 50 years ago, but there is no documentary evidence stating its origin, history of progression as a specialty, and work with agenda items. A gap exists between disability-related health and participation, which affects service delivery systems offered to persons with disability (PwD). Disability prevalence ranges from 0.47% to 14.4%. Illiteracy, maldistribution of wealth, and increasing prevalence of chronic diseases add to the burden of existing disability. It is necessary to involve all stakeholders in disability management to strengthen medical rehabilitation teams and improve service delivery while advocating for the rights and needs of PwD.

Canada has many isolated communities that are not connected to the electrical grid. Most of these communities meet their electricity demand through stand-alone diesel generators. Diesel generators have economic and environmental concerns that can be minimized by using hybrid renewable energy technologies. This study aims to assess the implementation of a hybrid energy system for an off-grid community in Canada and to propose the best hybrid energy combination to reliably satisfy electricity demand. Seven scenarios were developed: 1) 100% renewable resources, 2) 80% renewable resources, 3) 65% renewable resources, 4) 50% renewable resources, 5) 35% renewable resources, 6) 21% renewable resources, and 7) battery-diesel generators (0% renewable resources). A case study for the remote community of Sandy Lake, Ontario, was conducted. Hybrid systems were chosen to meet the requirements of a 4.4 MWh/day primary load with a 772 kW peak load. Sensitivity analyses were carried out to assess the impact of solar radiation, wind speed, diesel price, CO2 penalty cost, and project interest rate on optimum results. A GHG (greenhouse gas) abatement cost was assessed for each scenario. Considering GHG emission penalty cost, the costs of electricity for the seven scenarios are $1.48/kWh, $0.62/kWh, $0.54/kWh, $0.42/kWh, $0.39/kWh, $0.37/kWh, and $0.36/kWh.

Free space optics (FSO) has brought a solution to the ever growing need of high speed data transfer. It is sensitive to local weather conditions which results in a considerable loss of signal power over the communication path. This paper reveals the factors which are affecting the quality of data transmission and also states derived optimum parameters to get the finest solution for Bangladesh. Different weather conditions are considered and the parameters for both clear and foul weather conditions have been optimized. Simulation shows that the FSO system in worst weather condition achieves 2.5 Gbps data rate with 1550 nm wave length at the bit error rate (BER) of around 10−9 for 3km link range without using any optical amplifier. By using optical amplifier the link rang can be extended.
