The first integral method and its application for finding the exact solutions of nonlinear fractional partial differential equations (PDES) in the mathematical physics

In this article we apply the first integral method to construct the exact solutions of some nonlinear fractional partial differential equations (PDES) in the sense of modified Riemann–Liouville derivatives, namely the nonlinear fractional Zoomeron equation and the nonlinear fractional Klein- Gordon- Zakharov system of equations. Based on a nonlinear fractional complex transformation, these two nonlinear fractional...

Physicochemical characterization and inhibitive performance evaluation of Commiphora kestingii gum exudate in acidic medium

Gas chromatographic-mass spectrometry (GCMS), fourier transformed infra-red spectroscopy (FTIR) and physicochemical analysis of Commiphora kestingii gum have been carried out. The corrosion inhibition characteristics of C. kestingii (CK) gum on aluminium in sulphuric acid media were also investigated at 303 and 333K using gravimetric and scanning electron microscopic studies (SEM) method. The study revealed that the gum...

An electrostatic lens system for the deceleration of high intensity heavy ion beams

This work focuses on the design and implementation of an electrostatic lens system to produce high-intensity, low-energy ion beams, by means of numerical simulation of the beam trajectories (SIMION 7). The lens design was optimized using the simulation data obtained with a performance characteristics  of the electrostatic lens system. This lens system maintains good beam focal quality for the deceleration of heavy...
