Abstract: With the view to minimize the energy crisis due to the ever depleting non-renewable energy resources, this research aimed to apply nanotechnology to enhance the efficacy of solar energy power plant – a renewable energy resource. According to literature Concentrated Solar Power Plant system requires heat transfer fluid (HTF) for proficient working. This research reports the synthesis of novel, efficient heat transfer fluid doped with nano sized particle including carbon nanotubes and metal oxide i-e copper oxide. This nano heat transfer fluid (NHTF) has very low melting point in comparison to conventionally prepared molten salt mixture for heat transfer purpose which typically have high melting point characteristically 140°C or higher. Most prominently this NHTF has enhanced thermo-physical properties including high thermal stability and high specific heat capacity. These properties ensures effective increase in thermal energy storage (TES) which is a key factor in solar thermal power plant and make it broad range operating heat transfer fluid.

Abstract: The concentrations of four heavy metals [Lead (Pb), Aluminium (Al), Nickel (Ni) and Chromium (Cr)] in Synodontis clarias sampled in July, August and September (2014) at two locations along the Benin River, Delta State, were investigated by means of the atomic absorption spectrophotometer technique. A total of 24 samples of S. clarias with an average weight of 189g and length of 23cm were collected from the two locations along the river. Results showed that the total mean concentration values of metals recorded in S. clarias was: Pb (1.507mg/kg), Al (5.170mg/kg), Ni (2.380mg/kg) and Cr (0.075mg/kg). ANOVA showed significant differences (p<0.05) between the concentrations of each metal in S. clarias of Benin River at Koko during the different months of sampling. However, the concentration of Pb was not significantly different (p>0.05) in July compared to September, and July compared to August. Metal concentrations in the fish were generally within the acceptable limits set by Food and Agriculture Organisation (FAO) and World Health Organisation (WHO) in fish and fishery products, except for Nickel which exceeded the FAO recommended 0.5-0.6mg/kg limit. However, the concentrations of the heavy metals in water were much higher than recommended safe limits for human consumption thereby posing a direct health challenge to the people of the Koko community who depend on the water for domestic uses. There is an urgent need to check the sources of pollution in the area to forestall any imminent danger.

Abstract: This study focuses the possible impact assessment on environment of Lebukhali Bridge construction project which area is located in southern coastal part of Bangladesh. The main purposes of the study are to identify and analyse the potential environmental impacts, suitable alternatives and preparing environmental mitigation plan of this project. Both primary and secondary data were collected in doing this research. Primary data, such as the opinion from Union parishad offices, local NGOs, local people has been collected through in depth interview. Secondary data, such as statistics and reports on the parameter of environmental impacts, equation of Environmental Impact Value (EIV), procedure of Environmental Management Plan (EMP), was collected from past study reports, books and journals etc. The major environmental impact would be air pollution, water pollution and waste siltation, river erosion, migration, loss of Agricultural land etc. Environmental impact assessment is designed on the basis of ecological, physico-chemical and human interest. Environmental management plan prepared to minimize and control of negative impacts during pre-construction, construction and operation/management stages for its sustainability. The study found that there are no significantly sensitive ecological, physicochemical socio-cultural impact in the area. The environmental impact value was estimated +2 (Positive two) shows the acceptance of this project. This bridge will help to mitigate the transportation problem as well as increase the socio-economic development of southern coastal region of Bangladesh.
