A structured mathematical model of anaerobic conversion of complex organic materials in non-ideally cyclic-batch reactors for biogas production has been developed. The  model is based on multiple-reaction stoichiometry (enzymatic hydrolysis, acidogenesis, acetogenesis and methanogenesis), microbial growth kinetics, conventional material balances in the liquid and gas phases for a cyclic-bat...

The function of mate retention tactics is to prevent a long-term partner from defecting from the relationship and to ward off potential mate poachers. These tactics include Concealment of Mate, Appearance Enhancement, and Violence against Rivals. The current research is the first to investigate the performance of husband’s and wife’s mate retention tactics over time. We assessed 49 husbands and...

Sago industries effluent containing large amounts of organic content produced excess sludge which is a serious problem in wastewater treatment. In this study ozonation has been employed for the reduction of excess sludge production in activated sludge process. Central composite design is used to study the effect of ozone treatment for the reduction of excess sludge production in sago effluent a...

It is crucial to monitor the growth and development of a child in early stage of life to take early corrective action in time to ensure normal growth. Child health card (CHC) is a tool used to maintain records and monitor the under five children. The objective of this study was to find out the maternal awareness on CHC and factor associated with its retention. This was a cross sectional analyti...

The long-term viability and plasmid retention of recombinant Escherichia coli strains were investigated by real-time testing of master cell banks (MCBs) stored at the Roche Molecular Systems Culture Collection (RMSCC). MCBs at the RMSCC were cryogenically frozen and stored at -80 degrees C for long-term preservation. At regular intervals during a period of 5 to more than 10 years, representativ...
