خلفية البحث: مع دخول جائحة COVID-19 عامه الثالث ، من الواضح أن آثاره تمتد إلى ما بعد الجهاز التنفسي وهي مهمة سريريًا. قد يكون لهذه العواقب أيضًا تأثير على الصحة ونوعية الحياة. ربما يكون ثلث النساء قد عانين من تغيرات عابرة في أنماط الدورة الشهرية نتيجة للضغوط المرتبطة بوباء COVID-19. وقد يكون هذا التغيير ناتجًا عن التوتر والقلق. يمكن أن يكون عدم انتظام الدورة الشهرية أو غيابها مؤشرًا على انخفاض الخصوبة ، والذي يمكن أن يرتبط بحد ذاته بعدد من الحالات المزمنة ،و قد يتسبب النزيف الحاد في الإصابة بفقر الدم وله تأثير سلبي كبير على نوعية الحياة ويشكل عبئًا اجتماعيًا واقتصاديًا ضخمًا على النساء وأسرهن والخدمات الصحية والمجتمع. الاهداف : ان الهدف من هذه الدراسة هو النظر في تأثير عدوى فيروس كورونا على مستوى الهرمونات للمرأة (استراديول (E2) ، البرولاكتين (PRL) ، الهرمون المنبه للجريب (FSH) ، والهرمون اللوتيني (LH)) ، وكذلك الحالات النزيف الغزير الذي يحدث عند النساء العراقيات قبل انقطاع الطمث المصابات بفيروس كورونا لمدة شهرين إلى ستة أشهر على الأقل. المرضى وطرق العمل/ المواد وطرق العمل: اجريت هذه الدراسة البحثية في مدينة بغداد الطبية (العيادة الاستشارية) ، من تشرين الثاني (نوفمبر) 2021 إلى نيسان (أبريل) 2022. وشملت الدراسة 100 امرأة متزوجة في سن الإنجاب تتراوح أعمارهن بين 18 و 40 سنة. تم تقسيم عينة الدراسة إلى مجموعتين ، المجموعة الاولى 50 امرأة في سن الإنجاب مصابات بالنزيف الحاد بعد الإصابة بـ COVID-19 م لمدة أربعة أشهر على الأقل ، و 50 امرأة غير مصابات بالفيروس التاجي. النتائج: أظهرت نتائج هذه الدراسة ، بمقارنة متوسط ± SD للمجموعتين ، أن مستويات LH كانت ذات دلالة إحصائية عالية لدى النساء اللواتي عانين من نزيف حاد بعد عدوى COVID-19 مقارنة بالنساء غير المصابات بـ COVID-19 ، مع قيمة p 0.000. لم تكن هناك فروق ذات دلالة إحصائية في مستويات FSH بين المجموعتين. كانت مستويات PRL أعلى من الناحية الإحصائية بالنسبة للنساء اللائي عانين من نزيف كبير بعد الإصابة بـ COVID-19 مقارنة بالنساء غير المصابات بـ COVID-19 ، بقيمة p 0.003. كان E2 ذو دلالة إحصائية عالية مقارنة بالنساء اللائي عانين من نزيف مفرط بعد عدوى COVID-19 مقارنة بالنساء غير المصابات. الاستنتاجات: تشير نتائج هذه الدراسة إلى أن النساء بعد الاصابة بـ COVID-19 قد يكون لهن تأثير على أنماط الدورة الشهرية ، ولكن هذا التأثير كان مؤقتًا ويمكن أن يكون بسبب التوتر والقلق الذي يؤثر على HPA ومبايض النساء. قد يؤدي ذلك إلى اضطراب وظائف الجهاز التناسلي الأنثوي ، حيث تظهر مستويات مرتفعة من هرمونات الغدد التناسلية مثل LH و PRL و E2 وأحيانًا تؤدي إلى حالة نزيف حاد بعد الإصابة بفيروس كورونا.
The general assumption of linear variation of earth pressures with depth on retaining structures is still controversial; investigations are yet required to determine those distributions of the passive earth pressure (PEP) accurately and deduce the corresponding centroid location. In particular, for rigid retaining walls, the calculation of PEP is strongly dependent on the type of wall movement. This paper presents a numerical analysis for studying the influence of wall movement on the PEP distribution on a rigid retaining wall and the passive earth thrust location. The numerical predictions are remarkably similar to existing experimental works as recorded on scaled test models and ful
The scarcity of irrigation water requires procedures of specific. One of these procedures is the implementation of the rationing system (a period of the irrigation followed by a period of the dry). This system can have an impact on the properties of irrigation channels. Therefore, the study of rationing system for irrigation channels is important in both water resources and civil engineering, especially if they are constructed with gypseous soil. In order to assess the rationing system on gypseous canals stabilized with a specific ratio of cement, practical experiments were conducted to detect the effect of wetting and drying cycles on the physical and hydraulic behavior of this soil and calculation of some properties of soil such a

Conocarpus erectus L. widely planted all over Iraq and has different secondary metabolites, which has been used in treatment of anemia, cancer, fever and diarrhea. The present study aims to estimate the antibacterial activity of Conocarpus erectus leaves extracts on some microorganisms collected from patients with burn infection. The study began with the collection of Conocarpus erectus leaves in June 2018 from the trees in university of Baghdad. Maceration method was used to prepare aqueous extract, while Soxhelt apparatus was used to prepare methanolic extract. The results of phytochemical test show
... Show MoreIn this work, a weighted H lder function that approximates a Jacobi polynomial which solves the second order singular Sturm-Liouville equation is discussed. This is generally equivalent to the Jacobean translations and the moduli of smoothness. This paper aims to focus on improving methods of approximation and finding the upper and lower estimates for the degree of approximation in weighted H lder spaces by modifying the modulus of continuity and smoothness. Moreover, some properties for the moduli of smoothness with direct and inverse results are considered.
This paper assesses the impact of changes and fluctuations in bank deposits on the money supply in Iraq. Employing the research constructs an Error Correction Model (ECM) using monthly time series data from 2010 to 2015. The analysis begins with the Phillips-Perron unit root test to ascertain the stationarity of the time series and the Engle and Granger cointegration test to examine the existence of a long-term relationship. Nonparametric regression functions are estimated using two methods: Smoothing Spline and M-smoothing. The results indicate that the M-smoothing approach is the most effective, achieving the shortest adjustment period and the highest adjustment ratio for short-term disturbances, thereby facilitating a return
