The influence of pre- shot peening and welding parameters on mechanical and metallurgical properties of dissimilar and similar aluminum alloys AA2024-T3 and AA6061-T6 joints using friction stir welding have been studied. In this work, numbers of plates were equipped from sheet alloys in dimensions (150*50*6) mm then some of them were exposed to shot peening process before friction stir welding using steel ball having diameter 1.25 mm for period of 15 minutes. FSW joints were manufactured from plates at three welding speeds (28, 40, 56 mm/min) and welding speed 40mm/min was chosen at a rotating speed of 1400 rpm for welding the dissimilar pre- shot plates. Tow joints were made at rotational speed of 1000 rpm and welding speed of 40m/min f

Information security in data storage and transmission is increasingly important. On the other hand, images are used in many procedures. Therefore, preventing unauthorized access to image data is crucial by encrypting images to protect sensitive data or privacy. The methods and algorithms for masking or encoding images vary from simple spatial-domain methods to frequency-domain methods, which are the most complex and reliable. In this paper, a new cryptographic system based on the random key generator hybridization methodology by taking advantage of the properties of Discrete Cosine Transform (DCT) to generate an indefinite set of random keys and taking advantage of the low-frequency region coefficients after the DCT stage to pass them to

This study was conducted to estimate some heavy metals cadmium, lead, nickel and iron in 15 samples of Iraqi honey with 3 replicates for each sample which were collected from apiaries near potential contamination areas in five Iraqi governorates, including Baghdad, Karbala, Babylon, Diyala and Salah al-Din. The atomic absorption technique was used to estimate the concentrations of heavy metals, the results showed that there were significant differences at (P≤0.05) between the concentrations of these elements in the honey samples, the highest concentrations of cadmium 0.123 mg/kg were recorded in Baghdad, near the petrochemical production complex, lead 4.657 mg/kg and nickel 0.023 mg/kg in Babylon near the power plant, iron was

حاولنا, في هذا البحث القيام بعمل مراجعة نقدية وتقييم للثلث الأول من الترجمة العربية لرواية بيت الارواح والتي تعد اول عمل روائي ومن الروائع الادبية للكاتبة التشيلية المعاصرة إيزابيل أليندي, تكفلت دار النشر بلازا يانيس بنشر هذا العمل عام (1982) وترجمه الطبيب والسياسي السوري سامي الجندي. وتكفلت دار الجندي للنشر (1998) بنشر ترجمة الرواية.

This research describes Iraqi housing in the first decade of the twenty-first century, taking ALAdhamiya
as a model, depending on descriptive method of inductive approach to the study of this decade.
By doing the field study for three neighborhood in Adhamiya district. Which takes in consideration the
comparison between housing in the first period of the first decade of the twenty-first century with the
second period of this decade: the latest decades of 21th century. And for many aspects involving areas,
sizes, forming, direction of opening of housing and the function, to reach the most important transformation
of Iraqi housing in the first decade of this century in order to give a picture of the residential fact for t

شهدت السينما اثناء عمرها الممتد عبر نحو قرن من الزمن احداثا وتطورات سياسية مهمة، فضلا عن التطورات التقنية والفنية وكانت السينما حاضرة وشاهدة على احداث سياسية بارزة مر بها العالم قبل واثناء وبعد الحربين العالميتين الاولى والثانية وفترة الحرب الباردة وما بعده. وقد حظيت السينما اثناء النصف الاول من القرن العشرين باهتمام كبير من قبل الدول الكبرى والسياسيين فيها فضلا عن الاقبال التجاري للشرك
