Job stress is considered one of the most important obstacles that may appear in the work field. In order to deal with the obstacles and challenges , the idea to deal with job stress has come to address job stress as one of the most important trends that enable organizations to face those challenges through focusing on the role of job stress and the organizational climate of the organization.
The research deals with two variables: the job stress as an independent variable, and the organizational climate as a dependent one. Each variable includes five sub-dimensions. These dimensions have been involved in an interaction to form

Show MoreAuthentic materials are the most important tools that the teacher could use in class in order to make teaching go smoothly and effectively in transmitting the necessary knowledge to all students. This research has investigated experimentally the effect of using authentic materials in teaching English as a foreign Language, because a number of studies point out that the use of authentic materials is regarded a useful means to motivate learners, arouse their interest and expose them to the real language they will face in real life situations.
It is hypothesis that there is no statistical significance difference between the experimental group who taught English as a foreign language by using the authentic materials with those

The non – shallow shell theory is used for the analysis. The analysis based on considering the oblate spheroid as a continuous system constructed from two spherical shell elements matched at the continuous boundaries.
Throughout the results, it is shown that when the eccentricity reaches zero, an exact thin sphere solution is emerged and when the eccentricity equals one an exact thin circular plate solution is emerged. Therefore, the eccentricity of an oblate shell at medium value lies between these two values.
It was found that the Rayleigh – Rit
Idebenone, a synthetic analogue of ubiquinone (Co-Q10), is used for the treatment of Leiber’s hereditary optic neuropathy. Although it is almost completely absorbed from GIT, its extensive rate of metabolism makes its oral bioavailability less than 1%. This study aims to formulate the poorly water-soluble drug as nanoemulsion (NE) to increase drug solubility as well as transmucosal permeation and circumventing hepatic biodegradation by using transmucosal routes of administration such as intranasal rout to enhance drug bioavailability. Nanoemulsion components were selected through screening of the preferential solubility of IDB in several oils and emulsifying agents and subsequent formulation optimization through screening for their bes

The ligand (DPTYEDAPIBO) is prepared in three steps: The first step is the preparation of compound (A) which is prepared from the reaction of 2-Aminothiazol in ethanol solvent with Benzil. The second step involves the reaction of benzene-1,2-diamine with (E)-3-(hydroxyamino) butan-2-one to form compound (B). As for the third step, it involves the reaction of the product of the first step, compound (A), with the product of the second step, compound (B), to form the ligand. The structures of the ligand and its complexes are confirmed by FT-IR, 1H-
Lead acetate (Pb) is a hazardous heavy metal that is well-known to impair the functions of bodily systems and organs. This present study identifies the histopathological alterations that Pb toxicity causes in the liver of rabbits as well as the efficacy of ginger (Zingiber Officinale, ZO) in mitigating its negative effects. As ZO is a rich source of several antioxidants, this present study examines its ability to decrease Pb toxicity in test animals. A total of 30 rabbits were randomly divided into three groups (n = 10). The Control group was only fed distilled water, the Negative group was only fed a 2% Pb solution, while the Treated group was fed a 2% Pb solution as well as 100 mg of ZO extract per kilogram of body weight dail
