Abstract: This study seeks to determine the direction of causality between energy consumption (EC) and economic growth (EG), using annual data from 1981 to 2009. In our empirical analysis, we run an ordinary least square test to verify the statistical significance of the variables used and augmented form of Granger causality test to identify the direction of the relationship between these variables in the short run. Empirical investigations reveal that two variables are statistically significant at 5% and these variables are gross fixed capital formation and total labour force and they are positively related to real GDP while other variables such as crude oil consumption, coal consumption are positively related to real GDP but not statistically significant. Total electricity consumption on its own exert a negative influence on real GDP and also not statistically significant. ,
Key words: Energy consumption, Economic growth, electricity consumption, Nigeria.

Title	:	Determination of Potassium – 40 (40k) Concentration in Some Powdered Milk Samples Consumed In Delta State, Nigeria
Country	:	Nigeria
Authors	:	K. Emumejaye
	:	10.9790/4861-0230812

Abstract:This work is based on the determination of 40K in samples of powdered milk consumed in Delta State and also a brief discussion of radioactivity transference from the environment to mankind. Ten samples of milk were collected and analyzed for radioactivity concentration. The measurements were performed using a Laboratory fluorimeter, Models CBS- 380. The results obtained for the milk sample were compared to world Health organization (WHO) standard to ensure its safety to human consumption and were found to be lower than the permissible limits. Thus, there is full confidence in consumption of these milk brands.

Title	:	Approximate Solution of Schrodinger Equation for Trigonometric Scarf Potential with the Poschl-Teller Non-central potential Using NU Method

Abstract:The approximate analytical solution of Schrodinger equation for Scarf potential plus trigonometricPoschl-Teller potential is investigated using Nikiforov-Uvarov method. The bound state energy eigenvalues are given in the close form and the corresponding radial and angular eigenfunctions are formulated in the form of the generalized Jacobi Polynomials. The trigonometric Poschl-Teller potential causes the energy of Scarf potensial decreases as the orbital quantum number increases. The energy spectrum and the radial wave function of Scarf potential are produced by the absent of Poschl-Teller potential.
Keywords: Nikiforov-Uvarov method, Schrodinger equation, Trigonometric Scarf I, Poschl-Teller potential.
