    Both industrial and domestic applications of oils/fats have necessitated lipids research and the best method of extraction. The design and construction of the sheabutter extractor was made with the view of improving the nutrients in sheabutter. The construction was made within the available local raw materials.· The extractor- which is portable and manually operated, is meant to serve r-ur-al areas in the developing countries. The sheabutter extractor was tested and was found to be sa tis factory

    The Daunting Challenges of the Nigerian Electricity Supply Industry

    The future state of the Nigerian Electricity Supply Industry (NESI) is seemingly beginning to look promising amid the recent change in the country’s leadership and the increase in tariffs. Nevertheless, more still needs to be done to ensure the quality, availability and reliability of electricity supply to the citizenry; thus restoring the much-needed faith in the ongoing sector reforms as the Nigerian Electricity Regulatory Commission (NERC) set about implementing the Electric Power Sector Reform Act of 2005. With the wide array of energy sources available in the country such as biomass, large and small hydro, daily solar radiation of up to 7.5kWh/m2, coal, lignite, wind, municipal solid waste (MSW), niobium, natural gas and crude oil, sufficient electricity generation using all these available sources of energy should be a given but this is not the case. Hence this paper carefully analyses each segment of the NESI and successfully identifies the root-causes of constant power outages in the country which has led to a high unreliability of supply, with a view to proffering workable solution

    Modelling and Analysis of Powerline Temperature Surveillance with Optisystem Simulation

    A periodic variation of the index of refraction of a fiber optics is known as the Fiber Bragg Grating. It works on the principle of wavelength shifts in response to the modulation of the light source as a result of change in temperature above the reference point. This paper presents the design and analysis of Fiber Bragg Grating Sensor to measure and monitor the temperature change in powerlines for a particular range of temperature. Simulation was carried out on Optisystem to determine the peak reflectivity of the Bragg wavelength. It is seen that a change in the reflected spectrum of light is proportional to the change in temperature as shown in the FBG interrogator
