The objective of this thesis studying and deriving with some modification as a new approach of Runge-Kutta method including explicit, semi-explicit and implicit methods as well as studying stability of convergence of these methods.Also, one of most important themes of the thesis is to introduce variable step size and variable order methods using an extrapolation method which has the utility of controlling the local truncation error to be less than a prespecified tolerance error.

        This study aimed to investigate the inhibitory effect of probiotic microorganisms against Streptococcus pyogenes. A total of 85 pharyngeal swaps were collected from children infected with pharyngitis. Four isolates S. pyogenes were obtained and then evaluated for the activity of its spreading factors for infection streptokinase and hyaluronidase.

This project is aimed   to study the inhibition effect of wheat germ extract on some microorganisms, cancer cell line, and atopic dermatitis (eczema).The quantitative and qualitative detections of methanolic extract and methanol chloroform method extract by using gas chromatography–mass spectrometry (GC-MS) technique were achieved to detect the active groups.
