Design of a Renewable Energy Output Prediction System for 1000mw Solar-Wind Hybrid Power Plant
(International Journal of Research Science & Management, 2015) Ogherohwo E. P; Barnabas. B; Alemika T. E.
Problems associated with non-renewable energy sources such as fossil fuels make it necessary to move to cleaner renewable
energy sources such as wind and solar. But the wind and sun are both intermittent sources of energy therefore accurate forecasts of
wind and solar power are necessary to ensure the safety, stability and economy of utilizing these resources in large scale power
generation. In this study, five meteorological parameters namely Temperature, Rainfall, Dew Point, Relative Humidity and Cloud
Cover were collected for the year 2012 and used to predict wind and solar power output in Jos, Nigeria. The study used prediction
algorithms such as Regression techniques and Artificial Neural Networks to predict the output of a 1000mW Solar-Wind Hybrid
Power Plant over a period of one year. Individual prediction techniques were compared and Isotonic Regression was found to
have the highest accuracy with errors of 40.5% in predicting solar power generation and 35.4% in predicting wind power
generation. The relatively high levels of error are attributed to several limitations of the research work.
Parasitic Infection of Edible Terrestrial Gastropods in Benue and Plateau States, North-Central Nigeria
(THE INTERNATIONAL JOURNAL OF SCIENCE & TECHNOLEDGE, 2022-01) Adeleke Ezekiel Abayomi; Otokpa Ocha Juliet
An alternative to red meat due to cholesterol level has made large terrestrial snails a target. they could serve as a good
replacement and source of protein but their mode of life especially feeding and locomotion makes them prone to
parasitic infections. This study was aimed at investigating the parasitic infection of edible terrestrial snails in relation to
specie in some parts of North-Central Nigeria. a total of 579 edible land snails were collected during the wet and dry
seasons. Seven snail species belonging to three generals were identified. Out of the 579 collected snails, 447 (77.20%)
were positive for parasitic infections. All infected snails showed multiple infections. Infection rates of 82.88%, 77.69%,
67.12% and 53.85% were recorded from Agila, Jos, Utonkon and Wadata respectively. However, no significant difference
in snail infection in relation to location. (χ2= , p > 0.05). Parasitic infection of snail species revealed that A. fulica was
most infected (90.10%), this was followed by L. flammea (79.31%), A. marginata (77.42%), A. saturalis (75.58%). L.
aurora (74.73%), A. achatina (72.09%) and A. ovum (65.39%). No significant difference was observed amongst snail
species infection (p > 0.05). S. stercoralis recorded 100% infection rate in all snails, A. cantonensis 76.73%, while
Entamoeba sp. recorded the least (1.70%). Different parasites were also recovered from in the tissues/organs of the
snails observed. Public awareness on the public health implications of consuming terrestrial snails should be emphasized
by public health workers especially when eaten raw or undercooked. Snail farms should be encouraged rather than
consumption of snails gotten from the wild.
MARKETING INNOVATIONS AND PERFORMANCE OF INSURANCE COMPANIES IN NIGERIA: MODERATING ROLE OF INSTITUTIONAL SUPPORT
(Journal of Strategic Management, 2024) Yinka Calvin Ojeleye1)*, Hauwa Abdullahi Mustapha2), Saheed Adesunkanmi Oyede
The adoption of marketing innovations can contribute to the sustainability of a firm. However, research on the types of marketing innovations and their effects is limited. The study examined the dimensions of marketing innovations, their effects on performance of insurance firms, and how institutional support moderates those effects. The population of the study 504 management staff from 56 insurance companies, a sample size of 223 was determined using the Taro Yamane formula for finite population. Empirical data were collected and used to validate the model. Significant positive relationships are identified among each dimension of marketing innovation and performance. The findings are explained through the theoretical lens of resource-based view. Results show that both product and process innovation significantly contribute to the performance of insurance companies. Moreover, the relationship between process innovation and firm performance is significantly moderated by institutional support this is because with a favorable regulatory framework and activities aimed at encouraging innovation in the insurance business, institutional support is critical in easing the adoption and implementation of process changes. Whereas institutional support did not moderate the relationship between product innovation and firm performance. The study recommends that to maximize the significant positive effect of product innovation, Nigerian insurance firms should prioritize market research and client feedback. This study
contributes to the literature because it elaborates the conceptualization of marketing innovation and presents the dynamics of institutional support and firm performance. It also provides practical implications on how insurance firms can utilize marketing innovations to achieve business sustainability.
Postpartum contraception: determinants of intention and methods of use among an obstetric cohort in a tertiary hospital in Jos, North Central Nigeria
(International Journal of Reproduction, Contraception, Obstetrics and Gynecology, 2017) Otobo I. Ujah1*, Amaka N. Ocheke1, Josiah T. Mutihir1, Joseph A. Okopi2, Innocent A. O. Ujah1
Background: Postpartum contraception reduces the risk of unintended and rapid repeat pregnancies. A
comprehensive postpartum family planning (PPFP) service can enable women make adequate and informed choices on a preferred contraceptive method, initiating a method as well as encouraging them to use that method for a period depending on their reproductive intentions. Methods: This study aimed to determine women’s intention regarding uptake of postpartum family planning, the preferred methods and the factors associated with uptake. We conducted a cross-sectional study among women attending antenatal and postnatal clinics at the Jos University Teaching Hospital, Jos, Nigeria using structured
questionnaires. Data was analyzed using descriptive statistics and chi square test of comparison.
Results: Four hundred and five women participated in the study. The mean age of the respondents was 28.4+5.3 years. The previous contraceptive usage was 39.8%. A total of 262 (64%) women intend to use a method of postpartum contraception. The most preferred intended postpartum contraceptive was subdermal implant (19.2%) followed by injectables (18.4%) and intrauterine contraceptive device (14.7%). Reasons cited for nonuse of postpartum contraception include spousal refusal, effect on fertility, desire for further child bearing, religious beliefs. Conclusions: Counselling on postpartum contraception during the antenatal and postnatal period can help women make informed choices among the wide range of available contraception.
Occurrence of Enterohaemorrhagic Escherichia coli O157:H7 in Vegetables Sold in Jos Metropolis, Nigeria
(Biomedicine and Nursing, 2015) Okojokwu, O.J.1*, Akpakpan E.E.2, Ndubuisi J.C.3, Kolawole O.T.3, Okopi, J.A
Vegetables contaminated with pathogens can cause food poisoning, and can serve as vehicles for
transmission of Escherichia coli O157:H7 to humans. This study was therefore carried out to screen for the presence of O157:H7 strain of enterohaemorrhagic Escherichia coli in vegetables eaten raw and sold at the various vegetable markets in Jos metropolis. A total of 80 samples of vegetables namely; cucumber (Cucumis sativus), lettuce (Lectuca sativa), tomatoes (Solanum lycopersicon) and cabbage (Brassica oleracae) were collected from popular vegetable markets in Jos metropolis and analyzed. All vegetables were contaminated with Escherichia coli were isolated from 13.8% (11/80) of the vegetable samples, 25% (5/20) of cucumber had the highest contamination while tomatoes had the lowest contamination of about 5% (1/20). Escherichia coli O157:H7 (18.2%) was detected among the Escherichia coli isolates. All the Escherichia coli O157:H7 isolates were detected in cucumber thus accounting for 40.0% (2/5) of the Escherichia coli-positive cucumber samples. The presence of Escherichia coli O157:H7 in these vegetables poses public health concern and calls for improved hygienic practices in vegetable production and handling because these vegetables receive little or no heat treatment before consumption.
