Abstract The study aims to evaluate antifungal activity of petroleum ether extracts from leaves and stems of Rosmarinus officinalis and root of Glycerrhiza glabra , against fungi Fusarium oxysporium , Aspergillus flavus and Penicillium expansum. While the results of sensitivity of the fungi towards petroleum ether extracts showed different activity, petroleum ether extract of Rosmarinus officinalis showed more activity on Aspergillus flavus minimum inhibitory concentration(MIC) was 25 mg /ml and minimum fungicide concentration(MFC) was 37.5 mg /ml, followed by Fusarium oxysporium, (MIC) was 50 mg /ml and (MFC) was 37.5 mg /ml, finally Penicillium expansum (MIC) was 50 mg /ml and (MFC) was 75 mg /ml, used more concentration from petroleum ether extract Glycerrhiza glabra compared with petroleum ether extract of Rosmarinus officinalis and for the same study fungi, Aspergillus flavus was more sensitive, its growth inhibited by petroleum ether extract of Glycerrhiza glabra (MIC) was 100 mg /ml and (MFC) was 150 mg /ml, followed by Fusarium oxysporium (MIC) was 150 mg /ml and (MFC) was 200 mg /ml finally Penicillium expansum was less sensitive toward petroleum ether extract of Glycerrhiza glabra (MIC) was 200 mg /ml and (MFC) was 250 mg/ml. Analysis of petroleum ether extracts from leaves and stems from Rosmarinus officinalis and root from Glycerrhiza glabra was carried out to determine its contents from terpenoid compounds and flavones
This research seeked to create frame work for audit ISO as one class of investigation for special purpose. The suggestion frame work depend on five basic ingredients, there were nature of ISO audit, the people interested requirements to do this audit who process the audit and the problems effect this audit. Already discussed and study the requirements and recommendations from International Standardization Organization.

The grey system model GM(1,1) is the model of the prediction of the time series and the basis of the grey theory. This research presents the methods for estimating parameters of the grey model GM(1,1) is the accumulative method (ACC), the exponential method (EXP), modified exponential method (Mod EXP) and the Particle Swarm Optimization method (PSO). These methods were compared based on the Mean square error (MSE) and the Mean Absolute percentage error (MAPE) as a basis comparator and the simulation method was adopted for the best of the four methods, The best method was obtained and then applied to real data. This data represents the consumption rate of two types of oils a heavy fuel (HFO) and diesel fuel (D.O) and the use of tests to conf
