- ItemOpen AccessBIOGAS TECHNOLOGY AS A NON-CONVENTIONAL SOURCE OF ELECTRICITY GENERATION(Federal Polytechnic Ilaro., 2010-11) Omoregbee, HenryEfforts by the government to solve the energy crisis in the country over the years with the conventional methods of generating electricity has not yielded the desired result hence the need for alternative source of energy. The paper examines the possibility of exploiting the readily available organic waste (biomass production) and the major benefits over the conventional methods of generating electricity. The impacts of adoption of this alternative source of energy on the environment, the sustainability and renewability of the system were highlighted.
- ItemOpen AccessMANAGING INTERNET ACCESS IN AN ACADEMIC ENVIRONMENT(Federal Polytechnic Ilaro., 2010-11) Omoregbee, HenryA growing awareness of the educational benefits of the Internet has contributed to a sense of urgency among tertiary institutions worldwide to deploy it. However, with its many advantages also come the numerous challenges and problems. Managing internet access by students is particularly problematic, as valuable and costly Internet connection time is often used by students to access pornographic sites, read newspapers, play games, and to engage in online chatting, while other students cannot find ample computer time to do their work. The problem of students submitting downloaded works from the internet as their projects and assignments is rampant, while scarce resources are wasted printing irrelevant documents and visiting sites with questionable educational values. This paper therefore looks at the benefits of the internet in an academic environment, and highlights the major problems and challenges of providing internet access to students. The paper also reviews management policies for improving the benefits students derive from using the internet.
- ItemOpen AccessINVESTIGATING THE EFFECT OF ROAD CONDITION ON MAINTENANCE PROFILE OF TRICYCLE IN SOME LOCATIONS IN LAGOS METROPOLIS(Nigerian Society of Engineers (NSE) AGM meeting/Conference, 2011) Omoregbee, HenryThis paper looks at the effect of road surface conditions on the maintenance profile of TRICYCLE mode of transportation in the suburb of Lagos Metropolis. Primary data such as purchase, maintenance and route/road histories were analysed for five selected locations covering three (3) local governments. Results obtained revealed that road surface conditions constitute a downtime and maintenance costs of the TRICYCLES as follows 9.6%, 69%, 13%, and 12% for U turn, Meiran, Agege, Abule-Egba respectively. Since transportation system worldwide thrive on efficiency, reliability, availability and functionality, it was concluded that road condition have great effect on these attributes. It therefore stands to good reason that good road conditions minimize frequent breakdowns and conversely maintenance cost. It was finally recommended that based on this research, extensive road rehabilitation works be carried out to increase the efficiency of mass transportation system in the suburb of the Lagos Metropolis.
- ItemOpen AccessALTERNATE ENERGY SOURCES FOR CI ENGINES: A FOCUS ON NIGERIA(Energy Technology & Management Conference ETMCon, University of Ibadan., 2012) Omoregbee, HenryThe supply of energy through sources that have been adjudged not to be amenable to cleanliness and supportive of emission control, which are also finite, necessitates the search for alternative sources of energy. This becomes particularly important for transportation, specifically Internal Combustion Engines. It is also applicable to developing countries like Nigeria, which have the desire to develop technologically and would benefit from alternative technological paths to ensure the development, deployment and utilization of environmentally friendly technological products. Nigeria, a country rich in oil resources, would benefit from proper study and development of alternative products, specifically Compressed Natural Gas, which she has in abundance. CNG has shown a variety of capacities and adaptability, which makes it suitable to address endemic problems such as emissions, energy efficiency and thrift of conventional fuels like Gasoline and Diesel. It then becomes imperative that the pace of development and deployment of CNG consuming engines be fast-tracked. In this research, we hope to facilitate this process by comparing alternative power units, CNG units with conventional gasoline units. And also we hope that by employing the design principles and other factors that have made gasoline vehicles dominant in the passenger vehicle market, we shall arrive at an efficient and reliable CNG powered solution for passenger vehicles.
- ItemOpen AccessSOLAR ENERGY, A PANACEA TO RURAL ELECTRIFICATION UTILISATION: A CASE STUDY OF NIGERIA(Energy Technology & Management Conference ETMCon, University of Ibadan., 2012) Omoregbee, HenrySolar energy has always been one of the abundant renewable energies in Nigeria, and today there is a gap between its availability and utilization. This is underlined by the fact that the average sunshine hour per day is 6hrs and the reserve estimate is 3.5- 7.0KWh/m2-day. At present in Nigeria, electricity installed capacity sourced from coal, oil, water, gas and fossil nuclear materials is about 3500MW compared with projected electricity demand of 15,730MW by 2015. The continued usage of coal, oil, water, gas and fossil nuclear is faced with a lot of challenges ranging from the release of greenhouse gases, un-replenished and restricted installation among others. This paper examines solar energy utilization in Nigeria, vis-à-vis rural energy consumption and makes recommendations on how to fully harness solar energy to augment electricity generation into the national grid for increased power supply to rural communities.
