Uyo, Nigeria

The University of Uyo is located in Uyo, capital of Akwa Ibom State, Nigeria.The university was formerly known as the University of Cross River State . On October 1, 1991 the federal government of Nigeria established it as a federal university and the name was changed to the University of Uyo. The university inherited students, staff, academic programmes and the entire facilities of the erstwhile University of Cross River State established by Cross River State in 1983. Academic activities commenced during the 1991/92 academic session. UNIUYO has about 13 faculties and is expanding.The vice-chancellor is Professor Comfort Ekpo. In April 2010 the Emir of Fika, Dr. Muhammadu Abali Ibn Muhammadu Idrissa was appointed chancellor. Wikipedia.

Biomass, most of which is presently in the form of lignocellulose, is an important source of energy in many developing countries, particularly those in sub-Sahara Africa. The intensity of sourcing and use of these renewable natural resources in these countries are increasing owing to multifarious reasons. Series of reported studies and experiences have shown that this trend is not likely to reverse in the nearest future in these countries and that there is also very likely to be an upward global surge in this regard perhaps because of the expected positive responses to the increasing campaign for gradual energy switch to biofuels partly in order to contribute to the series of efforts at controlling the presently experienced global climate change as a result of fossil fuel combustion on one hand and finiteness of this non-renewable resource (fossil fuel) on the other. In line with these concerns, some developed countries are already increasing biofuels in their energy supplies, main source of which are expected to likely be from less developed tropical countries in future with series of projections concerning this. Therefore, there is the need for sustainable means of producing biomass for this purpose in these developing countries coupled with strategies that will capture future possibilities of supplying this resource to other parts of the world when the demand arise. However, literature showed that irrespective of the increasing importance of biofuels, the present awareness levels concerning this and investment in renewable energy technologies are still low, noting that most of the efforts in these regard appear to be more in the developed countries. Increased awareness and investments in bioenergy is therefore also imperative in developing countries bearing in mind this region's importance in its future sourcing and supply. The concept behind this article is to highlight the growing global importance and usage of biomass energy and their influence on both formal and informal global energy schemes, hoping this will be valuable to the various stakeholders that influence growth and development in this sector, particularly in the developing countries. © 2013 Elsevier Ltd.

Corrosion Science

Alloxazine (ALLOX) was tested as corrosion inhibitor for mild steel in 0.5M H2SO4 solution using non-electrochemical technique (gravimetric and UV-Visible spectrophotometric measurements) at 303-333K. ALLOX acts as inhibitor for mild steel in acidic medium. Inhibition efficiency increases with increase in concentration of ALLOX but decrease with rise in temperature. The adsorption of ALLOX was found to follow Temkin adsorption isotherm model. Both the activation and thermodynamic parameters governing the adsorption process were calculated and discussed. The adsorption follows a first-order kinetics. DFT study gave further insight into the mechanism of inhibition action of ALLOX. © 2010 Elsevier Ltd. Source

We present the bound-state solutions to the Klein - Gordon equation with equal scalar and vector modified Hylleraas plus exponential Rosen Morse potentials using the parametric Nikiforov - Uvarov method. We use the elegant approximation scheme to the centrifugal term. The bound state energy eigenvalues and the corresponding wave function are obtained. We also discuss the special cases. © 2012 Chinese Physical Society and IOP Publishing Ltd. Source

The corrosion inhibition of mild steel in sulphuric acid solution in the presence of polyethylene glycol (PEG), polyvinyl pyrrolidone (PVP), and their blends was investigated using weight loss and hydrogen evolution techniques at temperature range of 30-60°C. It was found that inhibition efficiency (η%) increases with increase in concentration of the homopolymers and decreases with increase in temperature. Inhibition efficiency was found to be synergistically enhanced on blending the two polymers with highest inhibition efficiency obtained for (PEG: PVP) blending ratio of 1: 3. The experimental data obtained fitted well into Temkin adsorption isotherm model. Physical adsorption mechanism is proposed from the trend of inhibition efficiency with temperature. The proposed mechanism is also corroborated by kinetic and thermodynamic parameters obtained. © 2010 Wiley Periodicals, Inc. Source

INTRODUCTION: Fourteen percent of maternal deaths globally occur in Nigeria. Low utilization of maternal health services for delivery may partially explain the high maternal mortality. The aim of this study was to examine the contribution of community factors in explaining variations in the use of health facilities for delivery in Nigeria.METHODS: Our sample consisted of 17,542 women aged 15-49 years drawn from 2008 Nigeria Demographic and Health Survey, who had had their last birth in the five years before the survey. We employed multilevel analysis to identify community factors related to the use of delivery care.RESULTS: In addition to several individual factors, region of residence was significantly associated with facility delivery. Women who lived in Northern Nigeria were less likely to deliver in a health facility than those who resided in the Southern part of the country. Residence in communities with a high proportion of women who had secondary and higher education significantly increased the odds of facility delivery whereas ethnic diversity was negatively associated with health facility delivery.CONCLUSION: Interventions aimed at promoting the use of health facility for childbirth should not only be implemented at the individual level but also tailored to the community level as interventions conceived without consideration for community context are likely to have limited impact. Increasing women's education in disadvantaged communities and region-specific interventions that increase access to health facilities are likely to have far-reaching impacts in reducing maternal mortality.
