يهدف البحث إلى تحليل التوزيع المكاني لتلوث المياه الجوفية بالعناصر الثقيلة في حي المدفعي ، بوصفها موردًا مائيًا يعتمد عليه في الاستخدامات المنزلية والزراعية . كما تناولت الدراسة تحديد العوامل المؤثرة في تلوث المياه الجوفية وقياس مستويات تراكيز العناصر الثقيلة ، مع بيان التباين المكاني بين آبار منطقة الدراسة والتباين الزماني بين فصلي الصيف والشتاء. ولتحقيق ذلك ، جرى اختيار 10 آبار موزعة ضمن منطقة الدراسة ، وجُمعت منها عينات مائية خلال فصلي الصيف والشتاء. وشملت الدراسة التحليل المكاني باستخدام نظم المعلومات الجغرافية ((GIS، فضلاً عن المعالجة الإحصائية للبيانات بالاعتماد على الإحصاءات الوصفيةواختبار (t) للعينات المترابطة للكشف عن دلالة الفروق بين الموسمين . شملت التحاليل المختبرية قياس تراكيز النحاس (Cu)، الرصاص Pb)) ، الحديد (Fe) ، الخارصين Zn)) ، المنغنيز (Mn) ، والفوسفات ( PO₄) ، النيكل Ni)) ، الكادميوم (Cd) ، وأظهرت النتائج ارتفاع تراكيز العناصر المدروسة خلال فصل الصيف مقارنة بفصل الشتاء ، مع تباين مكاني واضح بين الآبار، إذ بقيت الآبار ( 4 ، 6 ، 10) ضمن الحدود العالمية في معظم العناصر، في حين سجلت الآبار ( 3، 7 ، 9) أعلى القيم . كما بينت النتائج أن تراكيز الرصاص والحديد والفوسفات تجاوزت المحددات العالمية في جميع الآبار باستثناء الآبار (4 ، 6 ، 10) في حين تجاوزت تراكيز الخارصين المحددات العالمية في الآبار (1 ، 3، 9)، بينما بقي النحاس ضمن الحدود المسموح بها في جميع الآبار . وأثبتت الدراسة أن الأنشطة الزراعية والخزانات الامتصاصية والمخلفات الحيوانية أسهمت في تلوث المياه الجوفية في منطقة الدراسة .

This study aimed to statement jet stream and its impact in the anti-cyclone affecting the climate of Iraq. Through the use of simple correlation coefficient ( Pearson ) that there is a very strong relationship between high- Siberian and both of the jet stream especially during the winter or over the stations of North . Therefore we, observe the relationship be significant in most of the winter months , spring and autumn . Statistically significant , but are different between station and another station , while the study come to another Anti-ciyclon have a real ,significant and statistically relationship corrclation . But this relationship is less than which found in are much less it with the Siberian high , it depends on the type of stat

Whereas in art, improvisation also inters in all types of applied and performance arts as a foundation for launching and initiating it in music, painting, cinema, television and theater. In order to study the improvisation of the actor, the researcher put forward a theoretical study that included two sections. The first section is (the improvisation concept) and the second section is (improvisation in the show). The researcher, in the research procedures, took an intentional sample that was represented by the theatrical show (Rehearsal in Hell Play) and after t
