This work is focused on flow and mass transfer of a second grade fluid in a porous medium over a nonlinear stretching sheet with chemically reactive species and suction. The governing partial differential equations are transformed into highly nonlinear ordinary differential equations by using special transformations, which are solved numerically using a finite difference code. Favorable comparison with previously published work (n = 10 linear stretching sheet) is performed and the variations of dimensionless concentration and velocity profiles as well as mass transfer characteristics with various parameters are graphed and tabulated.

The experiment was designed to evaluate the role of garlic oil which contain high contens of sulphur componds for the control of blood glucose levels and oxidative stress that induced in rats by alloxan. The study conclude that garlic oil has the capacity to ameliorate the oxidative stress by increasing the antioxidant contens and reduced the free radicals production. Also, control the blood glucose levels may be by mechanism id dependt on insluin.

The kinetics of formation of intermediate complexes during the oxidation of iota- and lambdacarrageenan sulfated polysaccharides (CAR) as natural polymers by alkaline permanganate at pH’s ≥12 have been investigated using a conventional spectrophotometer. The reactions showed first-order dependences in permanganate and fractional-first-order kinetics with respect to carrageenans concentration. Kinetic and spectrophotometric evidences revealed the formation of intermediate complexes involving green manganate (VI) and/or blue hypomanganate (V) short-lived transient species. The influence of pH on the oxidation rates indicated that the formation of complexes is base-catalyzed. The kinetic parameters have been evaluated and mechanisms consistent with the experimental results are discussed.

The chromatic aberration of magnetic lenses with the field distribution in the form B(Z)˛Zn, for all integer n, have been studied as objective and projector lenses. These aberrations can be expressed in terms of Bessel function of the first and second type of the order 1/2n(n + 1). For this reason we resort to digital calculation. Care should be taking when making comparisons between positive and negative n value.

In this paper, Appell’s matrix function of two complex variables is introduced, starting from the hypergeometric matrix function with the studies of the properties and an elementary generating functions for Jacobi matrix polynomials are obtained.

This paper aims at studying the convergence of some iteration processes for mixed variational inequalities with convex nondifferentiable functionals and J-potential, J-coercive, J-pseudomonotone or J-strongly inverse monotone operators in uniformly Smooth Banach spaces. Our results generalize corresponding theorems of [2],[4]and[6].
