Foraminiferal analysis and palaeoenvironmental interpretation of borehole ET (BH-ET) in the Calabar Flank, South-eastern Nigeria
Foraminiferal biostratigraphy and palaeoenvironmental interpretation was carried out on core samples (5 samples between intervals 5-55 m) recovered from borehole ET (BH-ET) located in Etankpini area of the Calabar Flank, south eastern Nigeria. Lithologic description of the borehole samples were carried out and the borehole was sampled at 5 m interval. The samples were later composited at 10 m interval and a total of six...

Production of biogas by the co-digestion of cow dung and crop residue at University of the Punjab, Lahore, Pakistan
Anaerobic co-digestion is one of the most promising auxiliaries for treating waste because of the high energy redemption. Bio-digester is designed and apparatus installed for anaerobic co-digestion of cow waste with crop residue in order to manufacture biogas. Gas production is measured by using water displacement method. The experimental results show that 1 kg of cow dung can produce about 15 to 30 L of biogas per day....
