Integrating Renewable Energy and Smart Grid Technology into the Nigerian Electricity Grid System  [PDF]
Emodi Nnaemeka Vincent, Samson D. Yusuf
Smart Grid and Renewable Energy (SGRE) , 2014, DOI: 10.4236/sgre.2014.59021
Abstract: The electricity situation in Nigeria can be described as epileptic with no sign in view of improvement. This epileptic power situation affects the manufacturing, service and residential sectors of the economy which in turn affects the country’s economic growth. Even with the recent reforms in the power sector, more than half of the country’s population still lack access to electricity. The epileptic condition of the power sector can be attributed to the inadequate and inefficient power plants, poor transmission and distribution facilities, and outdated metering system used by electricity consumers. This paper attempts to present the way forward for the Nigerian poor electricity situation by reviewing the power sector as a whole and the renewable energy potentials. We identified the problems in the national grid and then proposed a smart grid model for the Nigerian power sector which will include renewable energy source. We believe that the content of this review paper will solve the poor epileptic condition of the power sector in Nigeria and also enable the proper integration of smart grid technology into the national grid.
The Necessity of the Development of Standards for Renewable Energy Technologies in Nigeria  [PDF]
Vincent Nnaemeka Emodi, Samson D. Yusuf, Kyun-Jin Boo
Smart Grid and Renewable Energy (SGRE) , 2014, DOI: 10.4236/sgre.2014.511024
Abstract: Clean energy is vital for the sustainability of any economy in the world. Many industrialized nations have increased their production capacity of renewable energy while other countries lacking the technical expertise and resource have resorted to import these technologies. The imported technologies mostly have standards that are followed by the manufactures while others are manufactured cheaply and exported to developing countries that do not have adequate standards and certification bodies. Nigeria which is a fast growing country has no existing standards to check the influx of renewable energy technologies into the country. This study stresses the need for the development of standards for renewable energy technologies in order to prevent the importation of substandard renewable energy technologies in Nigeria. The study reviews the renewable energy potentials in Nigeria, introduces the concept of standardization and discusses the development of standards for renewable energy technologies.

Keshav Singhania, G. P. Girish, Emodi Nnaemeka Vincent
Low Carbon Economy (LCE) , 2016, DOI: 10.4236/lce.2016.74014
Abstract: In this study, we investigate the impact of Odd-Even rationing of vehicles plying on the roads of the National Capital city of Delhi, India on air pollution levels by considering both residential and industrial areas of Punajbi Bagh, R.K. Puram, Anand Vihar, Mandir Marg, NSIT Dwarka and Shadipur of the city and have analyzed its impact by employing event study technique and by utilizing daily data of NO2, SO2, O3, PM10 and PM2.5. A ±15 day window has been considered for our analysis to assess the impact on air pollution levels pre-odd even rationing and post-odd even rationing and has statistically investigated whether this bold move by the State Government of Delhi has helped in the reduction of air pollution levels in the city or not. With the State Government considering implementing Odd-Even rationing permanently, the present study is intended to provide insights to policy makers to take an informed decision and also facilitate in implementing future policies for controlling air pollution levels in the city.
A Semantic Analysis of the Language of Advertising
LN Emodi
African Research Review , 2011,
Abstract: Semantics is the study of meaning system of a language and its approaches vary widely. In one view, meaning is the relationship between language and the external world (referential or denotative meaning), between a word and the concept it stands for. In another, it involves the mental state of the speaker, as reflected in a range of personal, emotive overtones (affective or connotative meaning). The uniqueness of the choice of words makes the language of advertising a specialized field of study. This paper presents an analytical study of the language features of English advertisements at a semantic level. In order to conduct a data-driven study, the writer has built a corpus of over 20 English advertisements. Through the detailed survey of allthe advertisements, the semantic features of the language of advertising are summarized and possible conclusions are given in the light of effectiveness of advertising. After a brief introduction to semantics and advertising language, the paper is focused on the linguistic realizations in English advertising from the semantic perspective. In the analysis, the use of connotative meaning ofwords, adjectives, coined words, mis-pelt words, repetition, metaphoric use of words, punning, non-existing words, the use of ambiguous statements are discussed to reveal fuzzy nature that are used by advertisers to achieve their persuasive ends. It goes further to treat the semiotic analysis of the language of advertising. The paper is then concluded with a brief summary. It is hoped that the paper can shed light on the semantic features of language of advertisements and also provide help to copywriters and English learners.
Towards reducing Mother-to-Child Transmission of HIV.
I Emodi
Nigerian Journal of Paediatrics , 2002,
Abstract: Women of child bearing age in Africa are particularly vulnerable to HIV infection, and this has led to an increase in the number of paediatric HIV infections reported due to mother-to-child transmission (MTCT) of HIV during pregnancy, delivery and breastfeeding. Various approaches to prevent or reduce MTCT have been established. These include elective Caesarean section delivery, avoidance of breastfeeding and antiretroviral therapy. For these strategies to be put in place, effective voluntary and confidential HIV counseling and testing for pregnant women should be implemented in African countries. Prevention of MTCT should also be considered as part of the wider management of maternal and infant health during prenatal, delivery and postnatal care. This review attempts to bring into focus the various strategies for a reduction in MTCT with special emphasis on the problems encountered in Africa. Key Words: HIV, Reducing perinatal transmission Nigerian Journal of Paediatrics 2002; 29: 55-60.
Corrosion Pattern of Pipeline Steel in Petroleum Pipeline Water in the Presence of Biomas Derived Extracts of Brassica oleracea and Citrus paradise Mesocarp  [PDF]
Nnaemeka Chinedu Ngobiri, Kaine Okorosaye-Orubite
Materials Sciences and Applications (MSA) , 2018, DOI: 10.4236/msa.2018.91009
Abstract: Corrosion inhibition characteristics of two biomass derived extracts from outer leaves of Brassica oleracea (BO) and Citrus paradise mesocarps (CPM) on pipeline steel were investigated using modified gravimetric method at ambient temperature (28 ± °C). Petroleum pipeline water was used to simulate a pseudo-anaerobic corrosion cell. The result obtained showed that corrosion was a continuous process in the closed system, while BO and CPM showed near equivalence corrosion inhibition efficiency of 91.45% and 89.44% respectively at the concentrations studied. The thermodynamic data suggests inhibition to be through molecular adsorption on metal surface.
An Assessment of Factors influencing Hospital Discharges Against Medical Advice of Paediatric Patients in Enugu: A Review of 67 Cases
AN Ikefuna, IJ Emodi
Nigerian Journal of Paediatrics , 2002,
Abstract: A study was carried out with the aim of determining the prevalence of discharges against medical advice (DAMA) at the University of Nigeria Teaching Hospital, Enugu as well as identifying the reasons for such requests. Data in respect of 67 patients who fulfilled the criteria for DAMA were analysed. A prevalence rate of 1.8 per cent was obtained for DAMA out of 4443 admissions over the study period. Poor financial support was the commonest reason for discharge against medical advice. Septicaemia was the commonest cause of admission accounting for 17 (25.4 per cent) followed by HIV/pulmonary tuberculosis in 15 (22.4 per cent) cases. Fifty-three (79.1 per cent) children were admitted without a formal referral letter and 51 (76.2 per cent) children were discharged within two weeks of admission while 45 (67.2 per cent) children belonged to the lower social classes. It is concluded that parental low social class, poor financial support and unpreparedness for hospital admission are risk factors for DAMA. A case is made for the implementation of the National Health Insurance Scheme as well as a review of the methods of counseling parents who ask for DAMA for their children or wards. This is important since the children are not directly involved in their parents'/guardians' decision to seek their discharges. Nigerian Journal of Paediatrics, 2002; 29:1-4.

AN Ikefuna, IJ Emodi
Nigerian Journal of Clinical Practice , 2007,
Abstract: Background Objective: The admission of children with sickle cell anaemia into the Paediatric ward of the University of Nigeria Teaching Hospital,(UNTH) Enugu was retrospectively reviewed to ascertain their pattern and outcome. Such data are useful in guiding future health policies on such children. Patients and Methods: Medical files of patients with sickle cell anaemia who were admitted between May1998 and April 2002 were analyzed. Their clinical features, investigations done, diagnosis on admission, complications and subsequent outcome of admissions were noted. Results: More children were admitted during the rainy season.(p<0.05) Male : Female ratio was 1.2:1. More children(70.4%) failed to comply with treatment of which a statistically significant number came from the lower social class (p=0.001). Infections were the commonest cause of admission (69.6%). Severe anaemia was the commonest complications (39.4%). Mortality occurred in 8.5%. Conclusions: Intensive counseling of patients, with the involvement of Social workers and health visitors, is strongly advocated. There is need for antibiotic prophylaxis for all children with sickle cell anaemia.
A Review of Policies, Acts and Initiatives in Rice Innovation System in Nigeria
IA Emodi, MC Madukwe
Journal of Agricultural Extension , 2008,
Abstract: A review of rice policies, acts and initiatives in Nigeria is presented under pre-ban period (1971-1985); ban period (1986-1995); and post ban period (1995-date). The key actors and the elements of acts and initiatives in the rice innovation systems were identified and presented. The growth in rice demand as a preferred staple has been so strong that production intensification and higher yields per ha was not sufficient to fill the gap and meet rice demand. In spite of successes recorded in rice production, there were a lot of gaps in the system. The policies, acts and initiatives failed to recognize the problems of the stakeholders because they were detached and foreign to the tradition and cultural practices of the stakeholders. The country’s policy on rice has been inconsistent and has oscillated between import tariffs and import restrictions including outright ban. Pressure from international financial organizations, such as the World Bank, World Trade Organization, and International Monetary Fund (IMF) helped in introducing distortions in the policies. Efforts by all stakeholders, the desirable political will by government and sound agricultural rice policy are essential to ensure that necessary conditions exist in meeting rice production. Key word: rice policy, rice innovation system.

AI Emodi, M Madukwe
Journal of Agricultural Extension , 2010,
Abstract: A nation’s ability to solve problems and sustain economic growth depends partly on its capabilities in science, technology, and innovation. In assessment of linkage mechanisms among key actors in rice innovation system in southeast Nigeria, actors were classified into six major groups according to their main activity in the system namely research agency, policy personnel, technology transfer agencies, farmers, marketers and consumers. These constituted the population of the study. A total sample size of 539 respondents, made up of 40 researchers, 76 policy personnel, 96 technology transfer agencies, 196 farmers, 51 marketers and 80 consumers were used. Percentages and means were used in data analysis. The study revealed that among the actors in rice innovation system, NCRI and IITA had link with technology transfer agencies, IITA had link with the Ministry of Agriculture. the Ministry of Agriculture had link with farmers ( X =2.51) and NAFDAC had link with researchers ( X =2.83). Among technology transfer agencies, ADP had link with researchers ( X =3.00), policy personnel ( X =2.88), farmers ( X =3.00) and Federal Ministry of Commerce had link with researchers ( X =2.73). Marketers had link with policy personnel ( X =2.72) and farmers ( X =2.68), while consumers had link with farmers ( X =2.72). The major linkage mechanisms that existed among the actors was dissemination of knowledge and information ( X = 3.00). The study concludes that for increase in rice production in southeast Nigeria, there is need for strong linkages among the actors in the rice innovation system.
