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 term "semantic exchange" was popularized in Arabic, especially in derivatives, grammatical structures, etc., but it came under different names or terms, including deviation, deviation, transition, displacement, tooth breach, replacement, attention, etc. In the rooting of this term through its study in language and terminology, and among linguists, grammar and others, we have reached a number of results, including The existence of a harmonization between the lexical and idiomatic meaning of the term exchange, and the phenomenon of semantic exchange is a form of expansion in language, and that the first language scientists They had turned to this And studied under Cairo for different names, as noted above.
The concept of transitional justice is newly emerging, as it was mainly associated with addressing issues of serious breaches and abuses of human rights during conflicts and situations resulting from violence and the use of force in societies that are in the process of democratization, as transitional justice aims primarily to restore civil peace and rebuild institutions The state needs multidimensional justice: a judicial system that achieves the rule of law, corrective restoration of the wounds of the past, and a distributive characteristic of the redistribution of wealth.
In this study multi objective optimization is utilized to optimize a turning operation to reveal the appropriate level of process features. The goal of this work is to evaluate the optimal combination of cutting parameters like feed, spindle speed, inclination angle and workpiece material to have a best surface quality Taguchi technique L9 mixed orthogonal array, has been adopted to optimize the roughness of surface. Three rods of length around (200 mm) for the three metals are used for this work. Each rod is divided into three parts with 50 mm length. For brass the optimum parametric mix for minimum Ra is A1, B1 and C3, i.e., at tool inclination angle (5), feedrate of 0.01, spindle speed of 120
... Show MoreThe nuclear structure of some cobalt (Co) isotopes with mass number A=56-60 has been studied depending on the effect of some physical properties such as the electromagnetic properties effects, such as, elastic longitudinal form factors, electric quadrupole moments, and magnetic dipole moments. The fp model space is used to present calculations using GXFP1 interaction by adopting the single particle wave functions of the harmonic oscillator. For all isotopes under consideration, the 40Ca nucleus is regarded as an inert core in fp model-space, while valence nucleons are moving through 1f7/2, 2p3/2, 1f5/2, and 2p1/2 orbits. The effects of core-polarization are obtained by the first orde
... Show MoreWisdom in the era before Islam is soo famous and so mature And Wisdom in the age of Islam {the holy quran and AI Hadeeth AI shareef }is dealt with by different meanings that agree with the contexts in which it occurs its contacs One of meanings is wisesaying that occuars in the Halal and Haram .As to the wisdom of the Amawy age ,it was some times absent since it was not dealt with by the great Poets of that age .In the Poetry of AL-FARAZDAK , Wisdom was little and it expressed religious and phsycological meanings because wisdom is amessage that has along –rang .
In this paper , some of lexical stylistic , syntactical stylistic devices , and one phonetic stylistic device are going to be illustrated in the study of the aphorisms of “life and death” . These stylistic devices are parallelism , hyperbole , alliteration , meiosis , irony , oxymoron , cliché , litotes , metalepsis , and loose sentences. This paper aims at identifying the functions and the frequencies of these devices. These stylistic devices make one speech and writing more interesting and help to get the attention of readers/ listeners

This research aims to analyze and explain the economic advantage to the concepts and measures that are related with added economic value.
Added economic value is considered as one of efficient tools which evaluates the performance of corporated industrial companies. in addition to that the research studied the traditional accounting measure which is used in evaluation of the project and industrial companies.
The research tested and analyzed the added economic value measure in some industrial companies and reached to a major recommendation:
- We must replace the traditional measure by the new measure that accounts the added value.
- We have to train all the workers whom working in the levels of a
Radiation treatment has long been the conventional approach for treating nasopharyngeal cancer (NPC) tumors due to its anatomic features, biological characteristics, and radiosensitivity. The most common treatment for nasopharyngeal carcinoma is radiotherapy. This study aimed to assess the better quality of radiotherapy treatment techniques using intensity-modulated radiotherapy (IMRT) and volumetric-modulated arc therapy (VMAT). The VMAT and IMRT are comparative techniques. Forty patients with nasopharyngeal carcinoma and forwarded for radiotherapy were treated with both advanced techniques, IMRT and VMAT, using eclipse software from Varian. The x-ray energy was set at 6 MV. The total prescribed dose was 70 Gy. The results show that the
