Let R be a commutative ring with identity and M an R-module. In this paper, we associate a graph to M, sayΓ(RM), such that when M=R, Γ(RM) coincide with the zero-divisor graph of R. Many well-known results by D.F. Anderson and P.S. Livingston have been generalized for Γ(RM). We Will show that Γ(RM) is connected withdiam Γ(RM)≤ 3 and if Γ(RM) contains a cycle, then Γ(RM)≤4. We will also show tha...

Background: The scientific imaging of works of art is crucial for the assessment of the presence and distribution of pigments and other materials on surfaces. It is known that some ancient pigments are luminescent: these include pink red-lakes and the blue and purple pigments Egyptian Blue (CaCuSi4O10), Han blue (BaCuSi4O10) and Han purple (BaCuSi2O6). Indeed, the unique near-infrared luminesce...

Nursing educators should recognize the need to develop innovative teaching strategies that would enhance student learning. Aim: The study aimed to evaluate the effect of applying a self-instruction package on cognitive performance among pediatric nursing students in Egyptian and Saudi settings. Methods: This quasiexperimental study was carried out at the Faculty of Nursing, Cairo-University, Eg...

Looking at Egypt before, during and after the Arab Spring, this paper examines the intersection of Christian Copts, the Muslim Brotherhood, the Egyptian army, moderate Muslims and secular groups. In turn, it examines the Obama administration's policies toward Egypt. It discloses the surprising finding that the only consistent aspect of the administration's policy toward Egypt has been outreach ...

For a sample of 94 firms, using data up to 1999, we find that retentions are more significant than dividends in determining prices of shares that are actively traded on the Egyptian stock market. However, for non-actively traded shares, the accounting book value is the most important determinant. Reductions in dividends are associated with a lack of liquidity and profitability. Dividend increas...

BACKGROUND Female genital mutilation (FGM) is still widespread in Egyptian society. It is strongly entrenched in local tradition and culture and has a strong link to the position of women. To eradicate the practice a major attitudinal change is a required for which an improvement in the social position of women is a prerequisite. This study examines the relationship between Egyptian women's soc...

Genetic predisposition increases the risk of familial breast cancer. Recent studies indicate that genetic predisposition for familial breast cancer can be ethnic-specific. However, current knowledge of genetic predisposition for the disease is predominantly derived from Western populations. Using this existing information as the sole reference to judge the predisposition in non-Western populati...

Knowledge can be transferred and imported across international borders. However, recent research shows that local cultures may affect the acceptance and application of such imported knowledge content. Egypt's adoption of IAS in 1996 provides an excellent opportunity to examine how conflicts between imported accounting standards and a nation's cultural values affect implementation of the new sta...

The inspiration and background research for this project is based upon Egyptian Faience because there is an interesting and coincidental synergy between the material properties of ancient Egyptian Faience and the material requirement for the successful 3D printing of ceramic powders. Originating in the 5th Millennium BC, Egyptian Faience was not made from clay, but instead composed of quartz an...
