Research ArticleOpen accessAll words, across the recordPeriodic Validation of High Antidiabetic Potentials of Unripe Plantain in Comparison with Glibenclamide and FansidarE. O. Jimmy, M. A. OkonProblem statement: The antidiabetic potentials of aqueous extract of musa paradisciaca (unripe plantain fruit) were investigated in alloxan induced diabetic rats. The extract at a dosage of 120 mg kg-1 produced a significant (p<0.001) reduction in glucose level by 85% on day 7, 78% on day 14, 64% on day 21 and 44% on day 28. Approach: The extract at … …American Journal of Pharmacology and Toxicology, Vol. 7, Issue 1 · 22 Mar 2012 · 7,997 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordGlobal Analysis of an Epidemic Model with Non-Linear Incidence RateS. A.A. El-Marouf, S. M. AlihabyProblem statement: In this study the equilibrium points and their local stability are found for SIQ and SIQR epidemic models with three forms of the incidence rates. Also, we study the global stability of the equilibrium by constructing the new forms of Liapounov functions. Conclusion/Recommendations: We explored the existence of Hopf bifurcation for some parameters in the given model. …Journal of Mathematics and Statistics, Vol. 7, Issue 4 · 28 Oct 2011 · 7,274 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordPeriodic Review Probabilistic Multi-Item Inventory System with Zero Lead Time under Constraint and Varying Holding CostNaglaa Hassan El-SodanyProblem statement: This study treats the probabilistic safety stock n-items inventory system having varying holding cost and zero lead-time subject to linear constraint. Approach: The expected total cost is composed of three components: the average purchase cost; the expected order cost and the expected holding cost. Results: The policy variables for this model are the number of periods N*r and … …Journal of Mathematics and Statistics, Vol. 7, Issue 1 · 29 Jan 2011 · 7,524 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordThe Role of Sine and Cosine Components in Love Waves and Rayleigh Waves for Energy Hauling during EarthquakeZainal Abdul Aziz, Dennis Ling Chuan ChingProblem statement: Love waves or shear waves are referred to dispersive SH waves. The diffusive parameters are found to produce complex amplitude and diffusive waves for energy hauling. Approach: Analytical solutions are found for analysis and discussions. Results: When the standing waves are compared with the Love waves, similar cosine component is found in both waves. Energy hauling between waves … …American Journal of Applied Sciences, Vol. 7, Issue 12 · 31 Dec 2010 · 7,582 accessesView PDF Cite
