Osogbo, Nigeria

Osun State University is a multi-campus university established by the Osun State of Nigeria. The university currently operates six campuses distributed across the six administrative/geopolitical zones of the state. Nigeria's National Universities Commission approved Osun State University on December 21, 2006, as the 30th State University and the 80th in the Nigerian university system. It has its campuses in Osogbo, Ikire, Okuku, Ifetedo, Ipetu Ijesha and Ejigbo which serves as campuses for Health science, Humanities and Culture, Social science and Management, Law, Education and Agriculture respectively.

This paper examines welfare effects of energy reform particularly petroleum products pricing reform in Nigeria. The data for 5000 households were collected to estimate a demand system for PMS, AGO and DPK. The survey contains information on the occupation and income of the household members, as well as on household expenditure and consumption as well as on a wide range of demographic and socio-economic characteristics. This study use marginal social cost approach to evaluate equity and efficiency implications of petroleum products subsidy reform in Nigeria. The reduction or removal of subsidy on PMS will save largest amount from government budget. When there is distribution concern, the marginal social cost of reducing subsidies on AGO is lowest supporting the reform that have been carried out by removing subsidies on AGO. However, marginal social cost for all petroleum products are extremely low suggesting reduction of subsidies on all petroleum products in Nigeria. These findings revealed that equity argument for continue subsidization of household kerosene can no longer be justified since marginal social cost is low. The reality is that apart from the NNPC outlets, there is no other outlet anywhere in Nigeria where kerosene is sold at the subsidised price. Source

It is difficult to predict the exact range of the validity of Darcy's law. The best method to ascertain the range is to conduct experiments and determine the actual relationship between the velocity, v, and the hydraulic gradient, i. For Darcy's law to be valid, the flow through soils must be laminar, which is true for Reynolds number less than one. However, it has been found that digressions from Darcy's law occur, even in the laminar regime, when inertial forces become effective. It was found that Reynolds number increases with increase in characteristics length, D, which represents the geometry of the passage of water in soils and the digression from Darcy's law increases with decrease in characteristics length with polynomial equation of second order. © 2011 ejge.

The performance of hydro broiler chickens fed graded levels of soaked wild cocoyam (Colocasia esculenta L. Schott) corms (SWCC) as a partial substitute for maize were investigated in a 28 day study. One hundred and twenty (120) 4 week old hydro broiler chickens of similar average weight were randomly assigned to 4 dietary treatments. Each treatment had 3 replicates of 10 birds each. Four experimental diets were formulated such that SWCC replaced maize at 0.00, 10.00, 20.00 and 30.00% in the diets. The birds were fed ad libitum and clean drinking water was provided throughout the period of the study. Parameters investigated include the growth performance, carcass characteristics, haematological and serum biochemical indices. Result of the growth performance showed no significant (p>0.05) difference in average weekly feed intake. Average weekly weight gain and cost per kilogram feed decreased (p<0.05); FCR increased (p<0.05) with increased inclusion of SWCC in the diets. Cost of feed per kilogram weight gain (CFPKWG) of birds fed on all SWCC-based diets were significantly (p<0.05) lower than control. Result of carcass analysis indicated that live weight, plucked weight, Eviscerated Weight (EW), Dressed Weight (DW), GIT and organs (kidney, liver and gizzard) were significantly (p<0.05) affected by dietary treatments. The highest (p<0.05) EW (72.91%) and DW (64.78%) of the control were similar (p>0.05)toEW (71.51%) and DW (63.33%) of 10% SWCC; but higher (p<0.05) than those of 20 and 30% SWCC. Organ weights reflected their roles in handling residual anti-nutritional factors in SWCC. Variations obtained in all the serum biochemical indices and haematological parameters investigated were not significant (p<0.05). This may suggest adequacy of the nutrients and absence of deleterious health implications for the birds. It was concluded that SWCC can economically replace 30% of maize in the diets of broiler finishers with no deleterious effects on carcass quality and health of the birds. © 2012 Knowledgia Review, Malaysia.

This paper presents a solution for multi-objective economic dispatch problem with transmission losses semidefinite programming (SDP) formulation. The vector objective is reduced to an equivalent scalar objective through the weighted sum method. The resulting optimization problem is formulated as a convex optimization via SDP relaxation. The convex optimization problem was solved to obtain Pareto-optimal solutions. The diversity of the solution set was improved by a nonlinear selection of the weight factor. Simulations were performed on IEEE 30-bus, 57-bus, and 118-bus test systems to investigate the effectiveness of the proposed approach. Solutions were compared to those from one of the well-known evolutionary methods. Results show that SDP has an inherently good convergence property and a lower but comparable diversity property. © 2013 IEEE. Source

The impacts of bacterial infection on cultivated fish species, African catfish, were investigated using oxidative stress biomarkers [lipid peroxidation (LPO) and protein carbonylation] and the activities of important antioxidant/detoxifying enzymes [catalase and glutathione S-transferase (GST)]. Fish were inoculated via oral gavage with one of the following treatments: 1 × 105 CFU/ml of Escherichia coli (EC1), 2 × 105 CFU/ml of E. coli (EC2), 1 × 105 CFU/ml of Vibrio fischeri (V1), 2 × 105 CFU/ml of V. fischeri (V2), gavaged with distilled water and not gavaged. Fish were maintained in the laboratory for 7 days after the bacterial inoculation, and the levels of LPO, protein carbonylation, GST, and catalase activities were determined in the muscle, gills, and liver of fish. Fish inoculated with bacteria (either E. coli or V. fischeri) had a significant higher levels of tissue LPO, protein carbonylation, and GST activities in a tissue-specific pattern (liver > muscle > gills). This appears to be related with the levels of bacterial inoculation, with effects more pronounced in fish inoculated with either EC2 or V2. The catalase activity did not differ significantly between the inoculated and fish that were not inoculated. The results of this study indicate that bacterial inoculation could result in oxidative stress in fish, and liver has a higher rate of oxidative stress per mg tissue compared to the gills and the muscle. © 2013 Springer Science+Business Media Dordrecht.
