Petroleum System Of Gindi Basin And Mubarak Sub-Basin, Qarun Concession, Western Desert, Egypt, Mostafa Hussien, Tharwt Abdel Hafeez, Mohammad Fathy, Mohammad El Ghamry
Al-Azhar Bulletin of Science
The study area is located to the west-southwest of Cairo, which includes Qarun and East Bahariya Concessions. Two main prolific sedimentary basins included; Gindi and Mubarak basins. Geophysical and 3D seismic data integrated with well logs, as well as geochemical data from 5 wells, all resulted in an accurate delineation of the structure traps and a reassessment of the elements of the petroleum system in this area. Mentioned basins are formed as a result of Late Cretaceous wrench tectonics. Such tectonic regime was responsible for generating oil entrapment and conduit faults in Cretaceous reservoirs. Detailed geochemical analysis proved that the …

Coronavirus Epidemic Model With Isolation And Nonlinear Incidence Rate, Afaf Zaghrout, Youssra Ali, Doaa Elpagouri
Al-Azhar Bulletin of Science
In our article we proposed an epidemiological model consisting of five compartments that describe corona virus disease with isolation. We developed an SEIR system to produce the dynamical behaviour of infection by adding isolation compartment F(t) (that is because of the isolation of the infected individuals will reduce the spread of the disease). We formulated our model with nonlinear incidence rate. First, we discussed the positivity and boundedness of the model. Then we calculated the basic reproduction number of the model under certain conditions. By analysing the local and the global stability of our model, it is noticed that this …

Back ground: PCOS is the commonest endocrinopathy among women of reproductive age. Its worldwide prevalence has been estimated between5-10%. Rotterdam criteria is known to be the most important in such patients.Vitamin D, a fat-soluble vitamin, can be produced in two ways: by intestinal absorption and endogenous synthesis from a precursor of 17-hydroxyl cholesterol on the skin with sufficient exposure to ultraviolet sunlight. Most references consider a serum 25(OH) vitamin D of < 20 ng/ml as vitamin D deficiency. Aim of the work: The aim of this work is assessment of the level of vitamin D in female have polycystic ovary syndrome & healthy female. Patient and methods: This is a case control study held in Misr Al-Gadeda Military Hospital in gynecology outpatient clinic from May 2020 - May 2021.Patients selected from attendees of the outpatient gynecological clinic and inpatient gynecological ward at Misr Al-Gadeda Military Hospital. Group A: 45 women diagnosed with PCO based on Rotterdam Criteria 2003. Group B: 45 fertile women without PCOS . Results: The results indicated that 25(OH) vitamin D was significantly lower in PCOS group than in control group. There were no significant correlations between 25(OH) vitamin D and age and BMI. Conclusion: PCOS is known to be one of the commonest endocrine problems between female of the reproductive age.25 (OH) Vitamin-D was significantly lower in PCOS group than in the control group.No significant difference was found in Vitamin D level related to age group and body mass index.
