يهدف البحث إلى تحضير سلسلة جديدة من معقدات العناصر الانتقالية ثنائية التكافؤ (الكوبلت, النيكل, النحاس, الخارصين ,الكادميوم والزئبق) مع المركبات الحلقية غير المتجانسة (L1) و(L2) والمشتقة من تفاعل 2,1- فينيلين ثنائي امين وسايكلوهكسان -2,1-ثنائي امين مع المركب الوسطي (Pr) على التوالي. شخصت المعقدات ذات الصيغة العامة :- [M(L1or L2)Cl2] بواسطة طيف الرنين النووي المغناطيسي البروتوني والكربوني وقياسات الأشعة تحت الحمراء والطيف الإلكتروني ودرجات الانصهار و التوصيلية المولارية و التحليل الدقيق للعناصر C.H.N.والنسبة المئوية للفلز %M والحساسية المغناطيسية. استنادا إلى النتائج المعطاه للدراسات المذكورة فقد تم اقتراح الشكل ثماني سطوح للمعقدات المحضرة من خلال ارتباط ذرات النتروجين الاربعة لمجموعة (NH) في المركبات الحلقية غير متجانسة (L1) و(L2) مع الأيونات الفلزية اضافة الى ايوني الكلور. ثم تم تحضير معقد النحاس النانويAuNPs −[CuL1Cl2] من خلط محلول معقد النحاس مع محلول الذهب النانوي(AuNPs) ، وتم إجراء التشخيص باستخدام طرق مختلفة ، بما في ذلك FTIR و UV-Vis و FESEM. تم اختبار قدرة التثبيط للمركبات المحضرة بما في ذلك معقد النحاس النانوي، ضد نوعين من البكتيريا المختارة (Escherichia coli) والموجبة (Staphylococcus aurous) بتقنية الانتشار ، حيث أظهرت النتائج أن قدرة المركب النانوي على تثبيط كلا النوعين من البكتيريا كانت أكبر من المركبات الحلقية غير المتجانسة(الليكاندات) ومعقد النحاس الحر, كما تم اختبار معقد النحاس الحر ومعقد النحاس النانوي على خط خلايا سرطان الرئة (A456) وخط الخلايا الطبيعي (REF) والمقارنة بين المعقدين حيث اظهر معقد النحاس النانوي نتائج ممتازة في امكانية اختباره مستقبلا كعلاج لسرطان الرئة
The problem of the tagged research (experimentation in the works of the artist Muhammad al-Kinani is an analytical study) dealt with the nature of the concept of experimentation and its work in the works of Muhammad al-Kinani. Which adopts the removal of the concept of style and artistic style and takes the experience away from the pattern of repetition The importance of the research comes through the identification of the materials founding the artistic work. The current research benefits the specialists in the field of arts from the students of studies with a new and renewed formulation of creativity.

Austenitic stainless steel-type AISI (316L) with a thickness of (2mm) was welded to carbon steel (1mm) using an MIG spot welding. The filler metal is a welding wire of the type E80S-G (according to AWS) is used with (1.2mm) diameter and CO2 is used as shielding gas with flow rate (7L/min) for all times was used in this work.
The results indicate that the increase of the welding current tends to increase the size of spot weld, and also increases the sheer force. Whereas the sheer force increased inversely with the time of welding. Furthermore, the results indicate that i
