...Show More Authors

Six isolates of A. pullulans were collected from many sources including Hibiscus sabdariffa (Roselle), old Roofs of houses and bathroom surface that referred as Ap ros1, Ap or2, 3, 4 and Ap bs5, 6 respectively, all these isolates were identified based on morphological characteristics and nutritional physiology profiles, all were able to utilize various carbon and nitrogen sources such as glucose, xylose, sucrose, maltose, ammonium sulfate, ammonium nitrate and ammonium chloride, also they showed positive test for starch and amylase, while α-cellulose, ethanol, and methanol were could not be assimilated and could not grow in 0.05% cycloheximide, the other tests referred to different results among isolates, the Ap ros1 isolate from Hibiscus sabdariffa (Roselle) was selected for production of pullulan.

           Four bacterial strains of two gram (+) and two gram (-) were chosen for the tests. The effect of pullulan coating on bacterial growth was observed in all tested strains, it was 63, 65, 70 and 75% for Bacillus subtilis, Staphylococcus aureus, Escherichia coli and Salmonella typhimuram respectively.

The weight loss of uncoated peach was 3.2, 4.8, 6.1, 7, 7.2, 8.3 and 9.1%, while in coated peach with 10% pullulan were 3.1, 4.5, 5.8, 6.2, 6.8, 7.9 and 8.9%, and in coated peach with 20% pullulan were 2.9, 3.8, 4.1, 4.6, 5.8, 6.4 and 7.6%, when these samples are stored at 3, 6, 9, 12, 15, 18 and 21 days respectively that stored at 25°C, and when uncoated and coated peach with 10 and 20% pullulan stored at 4°C . The weight loss in uncoated peach was 0.01, 0.06, 0.16, 0.23, 0.35, 0.46, 0.6, 0.68, 0.73 and 0.75%, while in coated peach with 10% pullulan were 0.01, 0.05, 0.12, 0.16, 0.2, 0.3, 0.5, 0.58, 0.64 and 0.71%, and in coated peach with 20% pullulan were 0.015, 0.02, 0.04, 0.08, 0.1, 0.12, 0.18, 0.3, 0.46 and 0.5%, when these samples are stored at 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 days respectively.

The weight loss of uncoated pear was 1.4, 2, 2.6, 4.4, 5.5, 6.4 and 7.2%, while in coated peach with 10% pullulan were 1.2, 1.6, 2, 2.4, 4.3, 5.2 and 6.6%, and in coated peach with 20% pullulan were 0.8, 1, 1.4, 1.6, 3, 4.6 and 5.4%, when these samples are stored at 3, 6, 9, 12, 15, 18 and 21 days respectively that stored at 25°C, and when uncoated and coated pear with 10 and 20% pullulan that stored at 4°C. The weight loss is 0.02, 0.07, 0.14, 0.16, 0.3, 0.33, 0.44, 0.45, 0.52 and 0.54%, while in coated peach with 10% pullulan were 0.02, 0.06, 0.11, 0.16, 0.21, 0.3, 0.36, 0.38, 0.44 and 0.46%, and in coated peach with 20% pullulan were 0.01, 0.05, 0.08, 0.09, 0.1, 0.16, 0.19, 0.24, 0.26 and 0.28%, when these samples are stored at 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 days respectively.

A fourth Order Pseudoparabolic Inverse Problem to Identify the Time Dependent Potential Term from Extra Condition
...Show More Authors

     In this work, the pseudoparabolic problem of the fourth order is investigated to identify the time -dependent potential term under periodic conditions, namely, the integral condition and overdetermination condition. The existence and uniqueness of the solution to the inverse problem are provided. The proposed method involves discretizing the pseudoparabolic equation by using a finite difference scheme, and an iterative optimization algorithm to resolve the inverse problem which views as a nonlinear least-square minimization. The optimization algorithm aims to minimize the difference between the numerical computing solution and the measured data. Tikhonov’s regularization method is also applied to gain stable results. Two

From Non‑Intervention to Non‑Indifference: What the African Union Has Really Learned about Crisis Management
...Show More Authors

Two decades after replacing the OAU, the AU’s record is best measured not by communiqués but by how fast it converts rules into results on the ground. In March 2022, the African Union’s Peace and Security Council (PSC) authorised the transition from AMISOM to ATMIS in Somalia — a reminder that, two decades after the African Union (AU) replaced the Organisation of African Unity (OAU), the Union’s rules are judged by execution, not intent. This article argues that the AU’s legal and institutional redesign shortened the warning‑to‑decision cycle and raised the credibility of enforcement, but performance still hinges on finance, logistics and political will. Where mandates are matched with money, enabling capabilities and enforc

Male protagonists in Alice Walker's The Color Purple; a Voyage from Oppression to Maturity and Reconciliation
...Show More Authors

Alice Walker's novel The Color Purple1983, whose events take place in the rural Georgia and addresses the most important issues in the early 20thcentury; like male dominant society and women submission to men, weaves a mosaic picture of male-female relationships. Black men like Alphonso, Albert and Harpo are portrayed as oppressors, cruel and they exercise power and violence over their wives and daughters. Through the negative portrayal of black male characters, Walker is accused to be a men hating writer because she ''Views oppression as an essentially masculine activity which springs from the male's aggressive need to dominate. In the novel, man is the premium mobile, the one by whom and t
