    Abstract: The study reports on the influence of nitrogen source on the biogas yield from cow (N'Dama) dung and rice husk. The digester performance for both feedstocks were evaluated using standard parameters such as; initial PH, water dilution, nitrogen source (guano and poultry droppings) and heavy metals. The source of innoculum used was cow rumen fluid. T... Show More

    Abstract: Airport terminals are energy intensive buildings. They are mostly thought to operate on a 24/7 scale and so indoor environment systems run on full schedules and do not have fine control based on detailed passenger flow information. While this assumption of round-the-clock operation may be true for the public areas of the airport building and so opp... Show More
