يعتبر التلوث احد المشكلات المهمة التي تواجه البشرية في الوقت الحاضر نتيجة للنشاط الإنساني المتزايد في مجالات الحياة المختلفة وتوجد أنواع مختلفة من اشكال التلوث، ويعتبر تلوث الهواء احد مظاهر التلوث خطورة، لذلك اجريت بحثا باستعمال انموذج الانحدار اللوجستي حيث يعتبر من النماذج الكفؤة والملائمة في عملية تحليل البيانات الوصفية ثنائية الاستجابة، وانموذج بروبت الذي يشبه أنموذج اللوجستي الثنائي في طبيعة المتغير التابع اذ يكون متغير نوعي يأخذ صفتين هما الصفر والواحد ويعتمد على دالة الكثافة الاحتمالية ودالة التوزيع التراكمي وانه يتبع التوزيع الطبيعي القياسي، ان هدف البحث هو بحث التلوث البيئي للهواء حيث يتم بحث تأثير المتغيرات المؤثرة التي تمثل الغازات المنبعثة في الهواء وهي (CO,NO,CH4,SO2,NO2,NOx) على متغير الاستجابة والذي يمثل الدقائق العالقة ضمن المحدد المحلي للتلوث خلال 24 ساعة (PM10,PM2.5) حيث تم اعتماد نسبة التلوث المنخفضة Law والمرتفعةHigh والتي تأخذ (0,1)، وتم تحويل هذا المتغير الى استجابة ثنائية على أساس النسب المقاسة لهذا المتغير، وتناول البحث ثلاث محطات في محافظة بغداد، هي (الوزيرية، وساحة الاندلس، والسيدية) ولقد توصل البحث الى ان ارتفاع مستوى التلوث بالدقائق العالقة بسبب المتغير المؤثر (CH4) في محطة الوزيرية، والمتغيرين (SO2,NOx) في محطة ساحة الاندلس، والمتغير(NO2,CH4) في محطة السيدية.
هدفت الدراسة الى تصميم جهاز يحاكي مهارة حائط الصد، وإعداد تمرينات خاصة باستعمال الجهاز المصمم لتطوير دقة الرؤيا البصرية لمهارة الضرب الساحق للاعبي الكرة الطائرة الشباب. استخدام الباحثان المنهج التجريبي، بتصميم المجموعتين المتكافئتين الضابطة والتجريبية. تم تحديد مجتمع البحث من لاعبي نادي الصناعة الرياضي (فئة الشباب) بأعمار (17 – 18) سنة. تم اختبار دقة الرؤيا البصرية لمهارة الضرب الساحق معالجتها احصائياً.

This study sought to understand the genetic association of this polymorphic system with risk of disease in Iraqi patients. Two outcomes of COVID-19, recovery and death, were also explored. ABO blood groups were determined in 300 hospitalized COVID-19 Iraqi patients (159 under therapy, 104 recovered, and 37 deceased) and 595 healthy blood donors. The detection kit for 2019 novel coronavirus (2019-nCoV) RNA (PCR-Fluorescence Probing) was used in the diagnosis of disease.

Citrus fruits are one of the consumer agricultural products of the Iraqi citizen. It is rich in vitamins and usedin many food industries as well as medicines. Classifying the amount of production of citrus treesaccording to the producing governorates has been done to find a map that shows the production of citrustrees according to Iraqi governorates. A cluster analysis method was used according to the hierarchicalmethod. The results showed that Najaf and Qadisiyah are the most similar in citrus production, whileSaladin and Najaf were the two governorates with the furthest distance in proximity matrix. Diyalagovernorate was clustered in the first cluster within two, three, four or five of the clusters for classifyingIraqi governorates covere
