    Evaluation of Cow Bone Ash (CBA) as Additives in Stabilization of Lateritic and Termitaria Soil
    (American Academic Scientific Research Journal for Engineering, Technology, and Sciences, 2021) Ariyo, Adanikin; Ajayi, Joseph; Busari, Ayobami; Fakorede, Ebenezer; Fase, Temidayo
    Continual pavement distresses on Nigerian highways, as well as environmental contamination from abattoir solid wastes such cow-bones have been a major concern. This study examined the usage of additives in stabilizing weak soils and enhancing their geotechnical properties utilizing Cow Bone Ash (CBA) on lateritic and termitaria soils. The following engineering confirmatory tests were carried out on the samples: compaction test, unconfined compressive strength (UCS) and California bearing ratio (CBR) test. CBA at 2%, 4%, 6%, 8%, and 10% were added to the soil samples. The study revealed that for lateritic and termitaria soils, the maximum amount of CBA that would allow for an increase in soaked CBR value was at 6% and 8%, respectively, while for the unsoaked CBR, the peak values was obtained at 8%. Also, the addition of CBA increased the UCS of both soil samples. The addition of CBA resulted in decreasing optimum moisture content (OMC) for termitaria soils as its pore spaces are filled up by the CBA while for the lateritic soils, increase in CBA resulted in increased OMC values. Also, the addition of CBA to both soil samples resulted in an increase in maximum dry density (MDD) values. The study revealed that termitaria soils have higher strength than the lateritic soils due to higher cohesiveness within its pore structure, lower OMC, higher MDD, UCS, and CBR values. The study concludes that the use of CBA to a maximum of 8% as an additive in stabilization of lateritic and termitaria soils is effective and therefore recommends its use in light and medium trafficked roads.

    INCESSANT POWER SUPPLY IN NIGERIA AND THE NEED FOR THE DESIGN AND PRODUCTION OF 100,000MW POWER PLANT
    (International Journal of Scientific & Engineering Research, 2019-02) Oshin, Ola A.; Adanikin, Ariyo; Fakorede, Ebenezer; Joseph, Ojotu
    The present unreliable and erratic power supply is a pointer to the fact that there is a great need for fault evaluation and reliability studies of electric power system in Nigeria. The recent blackout in the country has grounded many activities and has destroyed many industrial processes. Also, the power industries face a lot of problems. Some of the highest priority issues being generation of sufficient power, urgent clearance of faults, adequate protection and increase reliability of the system, that is, bringing a steady uninterrupted power supply to the consumers. The Nigerian power problem resulted to incessant planned, forced and unplanned outages. In addition, it has resulted to erratic and unreliable supply of electricity in the country. It has reduced productivity and has increased unemployment rate in the country to over 40million (this figure is over 70% of Nigerian youths. It has led many of the youths in the country to crime. It has led many of the deaths of many innocent people in the country. Hence, an analytical method is developed to assess the dynamic- reliability of the distribution system, as well as optimizes the occurrence of faults along each of the individual consumer point in a feeder in order to improve the performance of the system. This research publication therefore evaluates the occurrence of faults which is about 856 occurrences during a period of 8 years and outages which range between 1118 to 3785 hours per annum along the distribution lines, also the failure rates of each of the feeders were analyzed in order to improve on the supply of electricity in the distribution network. The reliability of the system which ranges between 8.57*10-12 to 9.548*10-5 were analyzed; and fault clearing techniques were carried out. Efforts were made to adequately assess the failure rates of the feeders which range between 0.003 and 0.001 and reliability of the distribution system. Efforts were also made to improve the performance of the system. As a result, it was possible to establish improvement techniques which ensure adequate and constant supply of electricity to all the consumers for industrial growth and employment: a basic solution to increasing crime rate in the country.

    RELIABILITY OF DISTRIBUTION NETWORKS IN NIGERIA: IKORODU, LAGOS STATE AS A CASE STUDY
    (International Journal of Engineering and Emerging Scientific Discovery, Casir Media Publishing, 2018-12-18) Oshin, Ola A.; Onile, Abiodun E.; Adanikin, Ariyo; Fakorede, Ebenezer
    Nigerians are experiencing a lot of difficulties as a result of poor Generation, Transmission and Distribution of electricity. As of 2016, the electricity energy consumption in the world from the world fact book revealed that the average power per capital (watts per person) in the United States is 1,377 Watts. In Canada, it is as high as 1,704 Watts per person and in South Africa; it is 445 Watts per person. The average power per capital in Australia is 1,112 Watts and in New Zealand it is 1,020 W per person. Whereas, the average electricity consumed in watts per person in Nigeria is just 14 Watts. This has put Nigeria in a rank of 189 out of 219 countries estimated. Currently, power generating capacity in Nigeria is estimated to be 6,803 megawatts, with average working capacity between 3,500 MW for over 170 million people (20.59 W/person). The power Companies in Nigeria face a lot of problems. Some of the highest priority issues being low generation of power, inadequate equipment and technical team for the clearance of faults, inadequate protection devices, transmission losses and low reliability of the distribution system. The Nigerian power problem has resulted to incessant planned, forced and unplanned outages. This has grounded many activities and has destroyed many industrial operations and processes. In addition, it has resulted to erratic and unreliable supply of electricity. It has reduced productivity and has increased unemployment and crime rates in the country. Hence, an analytical method is developed to study the dynamic- reliability of the distribution system, as well as optimizes the occurrence of faults and outages along the consumer point in each feeder in order to improve the performance of the system. A great need for fault evaluation and reliability studies of electric power system was observed. This research work analyzed the problems facing the Distribution System. Efforts were made to provide adequate solutions to the problems. The research work evaluated the occurrence and causes of faults and outages in the Distribution Network Area for a period of 8 years. In addition, it analyzed and reduced the effects of power losses along each of the feeders in the Distribution Network Area. This research work revealed the downtime, failure rate and reliability index along each of the eight feeders. It also improved the reliability and performance of the distribution system.
