The Impact of Interest Rate Spread on the Performance of Nigerian Banking Industry

This study examined the impact of interest rate spread on the performance of Nigerian banking industry for the period of 1986-2012. The study used OLS method of estimation to analyze the data generated from CBN statistical Bulletin and World Bank online data base. Testing for the properties of time-series, ADF test indicates that all the variables are integrated of same order I(1). The Co-integration test reviles that there exists a long-run relationship among the variables under consideration. The result shows that interest rate spread, negatively and significantly impact on bank performance in the long-run. Exchange rate and GDP was found to be positively and significantly affecting bank performance in Nigeria at the long-run. The result of the ECM indicates that 23.37 percent of the disequilibrium in the model will be corrected annually. Moreover at the short-run interest rate spread also negatively but insignificantly affect bank performance in Nigeria. Government should improve the macroeconomic environment by striving to develop the level of infrastructural facility in the country as well as reducing the level of insecurity in the country by cubing the menace of the Boko-Haram sect and that of Militancy in Nigeria. Therefore banks should not rely only on interest income if they must continue in business. Key Words: Interest Rate Spread, Bank Performance, Exchange Rate, Gross Domestic Product (GDP

Wind Energy Dynamics of the Separately Excited Induction Generator

This paper covers the analysis, dynamic modelling and control of an isolated self-excited induction generator (SEIG) driven by a wind turbine. The proposed dynamic model consists of induction generator, self-excitation capacitance and load model which are expressed in stationary d-q reference frame. The dynamic performance of SEIG is investigated under no load and on load. To predict the performance of the system, a MATLAB based simulation study using matlab embedded function block was carried out. Simulations from the variations of the speed and load display the dynamic behavior of the generator. A constant capacitor value of 100 micro-farads was used in this work. The simulation results obtained illustrate the changes in the voltage, currents, torque and magnetizing inductance of the generator. The wind velocity increase led to the increase in mechanical input from the wind turbine. This results in the increased rotor speed leading also to increased stator phase voltage. The obtained simulations also show that the output voltage of the induction generator depends greatly on its shaft speed and load; this poses a potential threat as it is capable of causing a significant variation in the power consumption in the load of the machine

Enhancing Graduate Employability: Why Higher Education Institutions have problems with teaching generic skills?

One debate among business owners and policymakers centres on whether higher education institutions (HEIs) have failed to transform the younger generation by developing their competencies, skills, values and behaviours to enable them to be fit for the world of work. While previous studies have considered the importance of skills development and its assessment in many contexts, there appears to have been limited scholarly research on employability issues within the higher education system (HES) in Nigeria. In seeking to address this, it is vital to understand how HEIs in Nigeria conceptualize generic skills and why HEIs have problems with teaching generic skills in their programmes. By adopting a qualitative approach, based on interviews with senior academics, industry executives and final-year undergraduates, this study found that many of the HEIs do not facilitate the teaching of high-level generic skills in their programmes. Some of the factors attributed to this include poor learning environment, lack of staff with industry experience, and over-dependence on theoretical content teaching. The findings are significant for reorienting the HE curriculum developers to align with the needs of the industry and society. Regarding implications for policy, we recommend that enterprise education be made mandatory for primary, secondary and tertiary education curriculum in Nigeria. Finally, we advocate more inclusive and interpretive research for greater understanding of the issues, and to offer useful data for policy-making and decision-making on the perspectives of preparing graduates for work

Effect of Plant Spacing on the Growth and Yield of Forage Plant, Maize, Intercropped with Cowpea (\u3cem\u3eVigna unguiculata\u3c/em\u3e sub spp. \u3cem\u3esesquipedalis\u3c/em\u3e)

Feed constraint is the most important impediment to improved livestock production in the Sub-Saharan African (SSA) countries (Agyemang 2003), as a result of seasonal shortages in the quantity and quality of forage from natural pastures that supply most of the feed for animals due to the prolonged annual dry season. Appropriate technologies to improve the performance of the local animal breeds and feed resources under the traditional system are generally lacking. Maize forms a major part of the cereal crops consumed by man and the residues serve as a source of fodder for livestock (Asawalam and Adesiyan 2001). Demand for maize has led farmers to reduce planting spacing. When crops are grown sole, spacing and planting pattern differ from when intercropped. Maize is known to be a very heavy soil nutrient utiliser and usually produces low yield in situations of low soil fertility and poor agronomic practices. Intercropping maize with legumes has shown prospects for improving maize crop yield and this would result in a reduction in the use of high cost synthetic fertilizers. The cowpea is an example of such legume and little work has been done on plant spacing for this crop in an intercropping system with maize. Plant spacing is an important agronomic attribute as it has effects on light interception which is the energy manufacturing medium of green parts of the plant (Ibeawuchi, et al. 2008)

Effect of direct-current magnetic field on the specific absorption rate of metamagnetic CoMnSi: A potential approach to switchable hyperthermia therapy

Materials with 1st order antiferromagnetic (AFM) to high-magnetization (MM) phase transition known for their inverse magnetocaloric effect, abrupt rise in magnetization and magnetoelastic coupling, are promising for application in combined simultaneous diagnosis and targeted cancer therapy. A therapy that combines alternating-current (ac) and direct-current (dc) magnetic fields for simultaneous magnetic hyperthermia therapy (MHT) and magnetic resonance imaging (MRI), using same magnetic particles for heating and as con- trast agents. We report a proof-of-concept study on the induction heating ability of 1st order metamagnetic material with moderate specific absorption rates (SAR) and no tendency for agglomeration, for potential MHT and MRI cancer therapy. CoMnSi, a metam- agnetic antiferromagnet (MM) was used in this study because of its desirable ability to rapidly switch from a low to high magnetiza- tion state in an applied dc bias field condition without particle agglomeration on field removal. The results showed that the magne- tization switched from \u3c 20 Am2kg-1 at 0.75 T to about 53.31 Am2kg-1 at 1.0 T applied dc field, a field large enough for magnetic resonance imaging. An SAR value of 10.7 Wg-1 was obtained under an ac field of 31.0 kAm-1 at 212.0 kHz. When combined with a dc bias field of 1.0 T, SAR values of 9.83 Wg-1 and 6.65 Wg-1 were obtained in the directions 45○ and 90○ away from the dc bias field direction respectively. These SAR values obtained from CoMnSi particles in the presence of simultaneous ac and dc magnetic field bias are in comparison, at least 25 times greater than those obtained from 2nd order magnetic phase transition Fe3O4 suspension. It is observed that Fe3O4 particles showed large suppression of SAR, and agglomeration under the same experimental conditions. This study shows the great potential of 1st order phase transition metamagnets for simultaneous MHT and MRI cancer therapy using MRI equipment
