The 33KV feeder from Elelewno substation which supplies the area was analysed using Dynamic Voltage Restorer (DVR) method. The method was used in Electrical Transient Analyzer Programme (ETAP). It was observed that load flow analysis is vital in understanding the ape rational nature of the network, by considering the following; Capacitive power, power before compensation, power after compensation, current before and after compensation, voltage drop, reactive current, supply current after compensation, losses in the distribution system and the ratio of loss without and with compensation. From the simulation there was low voltage profile and overloading of transformer along the distribution network. The voltage profile was improved by upgrading the network to standard power factor.

Izeoma Department of Foundation Studies Port Harcourt Polytechnic, Rumuola Phone No: +234 703 667 4797 E-mail: Chiizeoma@yahoo.com --------------------------------------------------------------------------- Abstract This paper examined the intergroup relations between the Ikwerre of the Niger Delta, South-South geopolitical zone of Nigeria and its impact on their culture. It analyzed the Ikwerre relations with her Kalabari and Okrika coastal neighbours, as well as the Etche, Eleme, Ekpeye, Ogba Abua and the Igbo of Imo state hinterland neighbours. The paper concluded that the internal developments which were stimulated by their contacts impacted significantly on their culture. Key words: Ikwerre, Intergroup Relations, Developments, Culture, Neighbour. Introduction Geographical factors aided the movement of people from one ecological zone to another in migration or interdependent relationships of trade exchange. These exchanges and contacts occurred even in pre-colonial times. The historical roots of inter-group relations of the Ikwerre with her neighbours, dates back to pre-colonial times but became prevalent from the 1850 onward when the Atlantic trade became emphatic on agrarian products as raw materials to the industrial western world. This galvanized the hitherto existing inter-group contact between the Ikwerre and her neighbouring potentates.

  • Distortion of Land Value Trends and Growth Patterns in Rural Communities in the Niger Delta Region Of
    Distortion of Land Value Trends and Growth Patterns in Rural Communities in the Niger Delta Region of Iyenemi Ibimina KAKULU, Nigeria Key words: Oil pipelines; land value; EIA, SUMMARY Nigeria is a major oil producing country and over 90 percent of its export earnings come from oil and gas production. On-shore and off-shore production; refining of crude oil; transportation and marketing processes are enabled by a maze of thousands of kilometres of pipelines criss-crossing the region. The positioning of the pipelines seriously interferes with the future land development potentials and land value growth patterns of rural communities. With increased awareness on global environmental management issues in Nigeria, environmental impact assessment studies (EIA’s) are conducted prior to the citing of major projects including pipelines and the enabling rights-of-way acquisitions. Unfortunately, such studies tend to concentrate more on environmental issues; health and safety; socio-economic and certain other factors. Little or no attention is given to the possible interference of these rights-of-way with the existing land value trends or the future land use development potential and growth. The result is that the restrictions of vehicular access over buried and /or surface pipelines rights-of-way has led to very slow, uncoordinated and haphazard development patterns within rural or semi-urban communities. The Igbo-Etche community in Etche Local Government area of Rivers state in Nigeria is a typical case. Despite its close proximity to the rapidly expanding and sprawling oil city of Port Harcourt, it has failed to develop in response to the pressure of demand because of the pipeline network and existing access restrictions.

Their common concern is to show not only that alternatives do exist, despite the neoliberal mantra of the “end of history”, but that many of these alternatives are currently unfolding – even if in many cases they remain invisible to us.

U. Rivers State University, Port Harcourt, Rivers State Faculty of Education Department of Vocational and Technology Education ABSTRACT: The study examined strategies for empowering rural women for sustainable livelihood in Etche Local Government Area, Rivers State. the objectives include to determine factors constraining women empowerment and to identify strategies for women empowerment in the study area. The study adopted a descriptive survey design. A multistage sampling technique was used to select 300 women (respondents). Data were collected using structured questionnaire designed in sections, with each section eliciting responses in respect of the research questions. A test-retest method was used to ascertain the reliability of instrument with r-value of 0.85. data collected were analyzed using descriptive statistics. A minimum mean of 2.50 was accepted as the standard. The findings showed that majority (43%) of respondents were between the age range of 40-49 years, majority (40%) had basic education while crop family processing was the primary occupation of majority of the respondents. The study also showed that women empowerment were constrained by gender discrimination; poverty; traditional belief, among others as equal opportunities for access to resources and elimination of discrimination to work and wages were some of the identified strategies for women empowerment. The study recommended that government at all levels should formulate policies that would encourage equal distribution of power right across gender.

U., Adigwe J. C. University of Nigeria, Nsukka, Nigeria This paper reviewed the scientific contents in Igbo culture. Description of the Igbos who constitutes an ethnic group occupying southeastern Nigeria was made. It x-rayed the pre-colonial, colonial, and post-colonial culture of Igbo people and identified the scientific cultural activities, which can be harnessed to meet the challenges of modern day globalization. The advent of science and science education in Igbo culture and its applications in various cultural activities of the Igbos both in the pre-literate and post-literate era were discussed. The implications of these for the development of Igbo nation were examined and recommendations were made on how the scientific cultural activities can be improved to enhance the integration of the Igbo culture into the modern-day globalization. Keywords: Igbo, origin, culture, evolution, science education, colonial, globalization, challenges Introduction Igbo Origin and Cultural Evolution The Igbo nation is not to be introduced in the community of nations.
