    Abstract: Biogas is mixture of gases, predominantly methane and carbon dioxide, produced by anaerobic digestion. In biogas production temperature of slurry is an important parameter that affects the rate of biogas production. The biogas digester was fed with cow dung before it was insulated. Ambient, biogas and slurry temperatures were measured. The temperat... Show More

    Abstract: Several voltage collapses have been experienced by most practical power systems in recent times in Nigeria. These have been mostly attributed to island formation within the network as a result of switching out of critical buses within the network. This paper assesses the stability of a practical power network of the Nigerian National Grid (NNG) wit... Show More

    Abstract: This paper presents a method that treats the soil by replacing a volume of the earthing portion with biochar instead of chemicals. The method contributes to reduce the earth resistance over long periods of time in order to avoid the expensive cost of these elements and their secondary effects. In the proposed method, a volume of soil from an earthi... Show More
