Abstract: Diabetes mellitus (DM) is increasing at an alarming rate both nationally and worldwide, there is increased evidence in correlation between vitaminD(vitD),calcium, phosphorus and magnesium, altered vitamin D and calcium homeostasis may play role in the development of type2 diabetes mellitus (T2DM) this study aimed to evaluate calcium, phosphorus and magnesium in vit D deficient T2DM. A cross-sectional study Was Conducted in Khartoum state, 120 type2 diabetic patients enrolled, aged between 25-80 years, then classified in to two groups based on vitamin D level (<30 ng/ml represent study group (deficient),while >30ng/ml represent control),Anthropometrics parameters (age, gender, and body mass index),diabetes duration were examined.Glucose,25hydroxyvitamin(25-OHVitD), calcium, phosphorus and magnesium level was measured. Prevalence of type 2 DM and BMI>26.5 more frequent in females (63%, 77.60%) respectively compared to males (37%, 65.90%).Diabetic females have highly vitD deficiency compared to males (75% vs. 45.45%),study showed correlation between vitD, calcium and magnesium (r =0.2365,0.4467) respectively and inversely correlated with phosphorus (r=0.4467), although there was no different in mean of calcium, phosphorus and magnesium between two group (blood glucose<180 mg/dl and blood glucose>180mg/dl)P-value <0.05. our preliminary findings conclude calcium, magnesium and phosphate are essential nutrients in vitamin D deficient T2DM patients.

Abstract: The binary quadratic equation representing the hyperbola is analyzed for its distinct integer solutions. A few properties among the solutions are presented Employing the integral solutions of the quadratic equation under consideration, a special Pythagorean triangle is obtained.

Abstract: This study examined the effect of home background, environmental factors, emotional intelligence and peer influence on students’ academic performance. For the successful execution of this research work, primary data via self-administered questionnaires was employed. These were administered to 150 randomly selected secondary school students (male and female) in Abeokuta metropolis of Ogun State vis-à-vis stratified and simple random sampling technique. Data collected were analysed electronically using SPSS 21. The analysis techniques employed were Percentages, Multiple Regression, Correlation Matrix and Coefficient of Determination. Results from the analysis revealed that home background, environmental factors and emotional intelligence have positive effect on students’ academic performance while peer influence has negative effect on students’ academic performance. However, of the three positive effects from home background, environmental factors and emotional intelligence, only the positive effects from environmental factors and emotional intelligence is statistically significant at 95% confidence level. Home background exerts insignificant effects on students’ academic performance. The negative effect of peer influenceis statistically significant on students’ academic performance.In terms of magnitude of effect, emotional intelligence has the most effect on students’ academic performance followed by environmental factors, home background and peer influence.The regression ANOVA indicates that the effects of home background, environmental factors, emotional intelligence and peer influence are jointly significant on students’ academic performance. In addition, home background, environmental factors, emotional intelligence and peer influencecontribute to approximately 30.9% of the variation in students’ academic performance. The multiple correlation coefficient value of 0.556 indicates that there is an average positive but imperfect relationship between the regressand (academic performance) and the regressors (home background, environmental factor, emotional intelligence and peer influence).

Abstract: This study examines the determinant of dividend payout in the Nigerian banking industry over the period 2004-2013. The study used five sample banks out of fourteen banks quoted on the floor of the Nigerian stock Exchange as at December 2012. Secondary data were used for the research work and the data were obtained from Nigerian Stock Exchange (NSE) fact book 2011/2012. The variables used were dividend payout, profitability, liquidity, Size and financial leverage. The data collected was analyzed using multiple regression and Pearson correlation. The finding revealed that profitability, liquidity, size and leverage proved to be the determinant of dividend payout of banks in Nigeria, while liquidity and profitability are the most critical factors determining dividend payout of banks in Nigeria. It is recommended that Banks should try all their best in improving their liquidity position since it has greater influence.

Abstract: This essay use the contact relation between the amplitude, shape, or, smooth degree of conventional log natural gamma ray, natural potential, deep lateral resistivity curve to analysis The sedimentary facies in the study area . According to the characteristics of different logging facies, 3 sedimentary facies and 26 sedimentary microfacies are identified. Including the micro facies of the heart, braided channel, the micro channel of the channel, the sand of the overflow, the microfacies of the sand table. On the basis of the identification of well logging facies, the micro phase diagram of the representative layer is precisely plotted.
