Abbar Mechanical Engineering Department College of Engineering, Al-Qadisiyia University Abstract An electrochemical cell consisting of two electrodes (Lead-6%antimony alloy cathode and copper anode, (99.9%)) was used to study the electrolytic preparation of copper powder with particle size less than (63µm) directly as powdery form. The effects of current density, metal ion concentration, sulfuric acid concentration, and electrolysis time on the weight percent of copper powder less than (63µm), yield and current efficiency were studied. keywords: acid; apparent; cathode; cell; cm2; cm^2; concentration; concentration=5gm; conditions; copper; copper ion; copper powder; current; current efficiency; density; effect; efficiency; electrodeposition; electrolysis=2hr; electrolytic; engineering; figure; form; high; higher; hydrogen; ion; journal; lower; metal; method; particle; percent; powder; preferred; preparation; prepared; process; properties; purity; qadisiya; reduction; sciences; sciences vol; size; sulfuric; surface; temperature; time; vol; weight; year; yield cache: jqes-10.pdf plain text: jqes-10.txt item: #2 of 545 id: jqes-100 author: Shakir Al – Bahrani, Hussein title: FIEL STUDY OF THE MOST IMPORTANCE NOISE POLLUTION SOURCES IN LIVING REGIMES AT AL-NAJAF AND AL-KUFA CITIES date: 2017-07-19 words: 4803 flesch: 101 summary: شخصــا) ١٥٠(حجــم العينــة التــي وزعــت علــيهم اســتمارة االســتبيان بلغــت إن -:كاآلتيفكانت بيانباالست االطباء، النصر، السالم، النفط، الغري، المكرمة، السعد، العدالة، الغدير، االميـر، :أحياء مدينة النجف -١ .المثنى، دور االساتذة، العسكري، الهندية، القادسية، الجزيرة، المدينة القديمة .ميسان، ميثم التمار، كندة، المدينة القديمة :أحياء مدينة الكوفة -٢ :نتائج االستبيان (Microsoft access)البيانـات فـي برنـامج حاسـوب مناسـب إدخـالاالستبيان تم بعد جمع استمارات يشكو ،،، لضوضاء ثالثة نساء يعانون من األمراض العصبية بسبب ا و تقدر األضرار التي تصيب العمال و تؤدي إلى االنقطاع عـن ، من الضوضاء في المصانع التي يعملون فيها )٢٠٠٣ keywords: auditory; cities; effects; generator; importance; kufa; living; najaf; noise; pollution; pressure; public; questionnaire; regimes; research; social; sound; sources; www.feedo.net/environment/environmentindex; أحياء; أخـرى; أخـــرى; أصــوات; أطفال; أعلى; أكثـر; أما; أنها; أنواع; أهـم; أهم; إال; إحدى; إلــى; إلى; إنشاء; األذن; األصــوات; األصوات; األطفال; األمراض; اإلنسان; االجتماعية; االستبيان; اذا; ارتفاع; اقل; البحـث; البيئة; البيئيـة; التأثيرات; التردد; التركيــز; التعـرض; التــردد; التــي; التلــوث; التلوث; التنفسي; التي; الجهــاز; الجوي; الدراسات; الدراسة; الدم; الدين; الذي; الرقم; السائبة; السابقة; السامع; السريعة; الســمعي; السكنية; السمعية; الشارع; الشعبية; الشـخص; الشــكل; الصحة; الصــوت; الصناعية; الصوت; الصوتية; الضغط; الضوضاء; الضوضائي; الضوضــاء; العالمية; العامة; العمل; الغرض; الــدائم; الــديزل; الفــرق; الفقــدان; القادسية; القادسية للعلوم; القديمة; المارة; المحــور; المختلفة; المدارس; المدن; المدينة; المزدحمة; المستويات; المسموح; المصدر; المصــدر; المطارات; المطـار; المناطق; المنحني; الموجات; الموجة; المولدات; المولدة; الناتجة; الناقل; النجف; الهندية; الهواء; الوسط; الى; الھندسية; بعد; بعض; بعـض; بـأن; بـين; بموضوع; بها; بوجـــود; بوحدة; بوحـــدة; بين; تأثير; تؤدي; تتـراوح; تساوي; تسـبب; تشـغيل; تصيب; تــم; تكـون; تلــك; تمثل; توجد; جامعة; جدول; حسب; حيث; حيــث; خالل; داخل; دراسة; دور; دون; ديســيبل; ديسيبل; ديسيبل(مستوى; ذات; ذلـك; ذلك; سرعة; سطح; سـمعية; شدة; شــدة; شكل; ضغط; ضـغط; ضوضـاء; ضوضـــاء; طول; طويلـة; عاليـة; عدم; عشوائية; عـن; علـــى; علـى; على; عليها; عند; عنـد; غير; فأن; فان; فترة; فـأن; فـان; فــي; فـي; فقط; فهـي; قبـل; قــدرة; قياس; كان; كـل; كما; كمـا; كمـــا; لتقليل; لفتـرات; للعلوم; لها; لهذا; لهـا; ليس; مثـل; مثل; مجلة; مجلة القادسية; مدينة; مسار; مستوى; مستويات; مســتوى; مشـكلة; مصادر; مصــادر; مطار; معين; مـع; مـــع; مــن; مـن; مولـدات; هذا; هذه; هـذا; هــذه; هــو; هــي; هـو; واحـدة; والجهاز; والكوفة; وان; وبين; وخاصة; وذلك; وسائل; وضغط; وضــع; وغيرها; وفتـرة; وفي; ولكن; ونوع; ويمثل; يسـاوي; يطلق; يعرف; يمثــل; ١٠٠; ١٩٨٣،احمد; ٢٠٠٤،بدر; ٢٠٠٩; ٢٠٠٩ ٤العدد; ٤العدد cache: jqes-100.pdf plain text: jqes-100.txt item: #3 of 545 id: jqes-103 author: K.

From the experimental study the results show that the use of CFRP sheet to upgrade the R.C beams containing tensile reinforcement lap splices has significant effect on the behavior of these beams such as ultimate load, cracking load, deflection and mode of failure where the percent increase in ultimate load was about (11-47)% and with elimination the possibility of the brittle failure. keywords: -al; bars; beams; behavior; bond; brittle; cfrp; concrete; confinement; control; cracking; cracks; deflection; diameter; effect; element; ends; engineering; exp; experimental; external; f12; f16; failure; figure; finite; flexural; journal; lap; lap splices; length; load; longitudinal; mode; node; qadisiya; region; reinforcement; results; rupture; sciences; sheet; specimens; splices; splitting; steel; stirrups; strengthening; study; tensile; tensile failure; tension; tested; theo; ultimate; ultimate load; university; vol; wrapping; year cache: jqes-325.pdf plain text: jqes-325.txt item: #197 of 545 id: jqes-326 author: A.

The Results : The probability density functions of amorphous silicon , a-Si , with dangling bonds and correlation effect among them, is studied through four obtained curves for FtA using MATLAB, the first curve is for variation of probability density function of a-Si , FtA , with position of acceptor like trap level EtA for different values of free carriers concentrations n and p at certain donor like trap level, the second is for variation of FtA with position of acceptor like trap level EtA for various positions of donor like trap levels at certain concentration of free carriers, the third is for variation of FtA with acceptor like trap level EtA for different values of temperature and the fourth is for variation of FtA with position of acceptor like trap level EtA for different values of captured cross section ratios RA and RD .The calculations were performed regarding the value of intrinsic concentration ni = 1.9 x 105 cm-3 , ratios of capture cross section RA = RD =100 , temperature T = 25 C0 and position of Fermi level Ei = 0.8 ev. keywords: acceptor; amorphous; band; bonds; carriers; concentration; correlation; cross; density; different; donor; effect; engineering; equal; eta; free; fta; function; gap; journal; level; position; presence; probability; qadisiya; region; sciences; silicon; states; temperature; trap; values; variation; vol; year cache: jqes-36.pdf plain text: jqes-36.txt item: #229 of 545 id: jqes-360 author: S.
