تعد عملية سحب الأسلاك النحاسية من عمليات التشكيل على البارد و التي يستخدم فيها النحاس بحالته النقية بشكل أساسي في صناعة النواقل الكهربائية على اختلاف أقطارها و مقاطعها, و تعد القطوع و التشوهات الحاصلة أثناء سحب الأسلاك من أبرز المشاكل التي تتعرض لها ماكينات السحب لما لها من تأثير في ارتفاع زمن التوقفات و انخفاض معدل الإنتاج و زيادة حجم الهدر و التالف. لقد تم على مدى عامين بالتعاون مع شركة "الكابلات السورية الحديثة" دراسة ماكينة سحب أسلاك النحاس الثقيلة ذات النوع HENRICH-GERMANY-2Lines-Max.Production 25ton/24hr و مراقبة أدائها و دراسة العوامل التي تؤثر على سير العملية الإنتاجية لها. حيث تم تصنيف هذه العيوب بناءً على 50 عينة تم ربطها بالفحص البصري أو بالصور المجهرية اللازمة بناءً على تحميل و تحديد أسباب حدوثها مع مناقشة النتائج إضافة لإدراج مخططات إحصائية أفضى ذلك كله إلى تقديم توصيات عامة بغية الحصول على الجودة المرجوة للسلك المسحوب.
The copper wire drawing is one of cold forming operations which basicly the copper is used as pure material for various diameters & sections in electrical conductors industry. By cooperation with S.M.C company for cables industry in Damascus – Syria, a research has been done during 2 years on rod breakdown heavy drawing machine -HENRICH - GERMANY- 2 lines- with max productivity 25 ton/24hr. 50 samples of copper wire breaks and deformations have been studied & analyzed, thus the defects are classified in main statistics diagrams in gold of give main instructions that contribute in raising the quality level of local copper wire manufacturing & giving a whole view about this industry.

In this work, it has been studied Compton Effect using the 662 keV gamma rays from a radioactive source of cesium-137 (137Cs) intensity (3.33×105 Bq) on Aluminum rod (who plays scatter). It has been measured the differential cross section, and the ex
perimental values of differential cross section compared with theoretical values given by Klein - Nishina equation.
The mid-transverse section is considered one of the significant sections in the
shiphull, because it exists in the middle of its calculated length, where the bindings
moments reach the maximum, in consequence the hull strength can be determined thr
ough
the strength of this section. Its design process includes the determination of the dimensions
of plats and different framing beams and considered one of the important stages in the hull
design process. This research includes the estimation of calculated values of binding
moments, inertia and resistant’s moments of this section area, initiated from the providing
conditions of critical strength and fatigue strength. It also includes, the formals used for the
determination of longitudinal elements dimensions through the transverse thicknesses and
metal distribution type among them. The longitudinal strength of the hull was evaluated
according the perpendicular and tangential stresses.
This work aims to find the differential scattering cross-section
for X-ray
scattered by aluminum target with angles in intervals in accordance to both
polarization cases ( completely – partly).
In addition, the relative scattered intensity and po
larization degree have been
presented as a function of scattered angles and the extreme values are found for each curve.
In this paper the design and development of a device (sensors system) to
study the effect of operational flaws of dowel Albetona engraved:
In order to find the appropriate resistance R factors for the to concrete
bored pile executive defects, whic
h include 15% or less than the cross section of
the to concrete bored pile by conducting tests on miniature models of the pegs
under the influence of horizontal and vertical loads.
Using high strength concrete made a big step in designing and
constructing reinforced concrete structures. In this research, shear
resistance of high strength concrete beams with average resistance
of (65Mpa) and without shear reinforcement was ca
lculated by
making Experimental tests, also we studied the effect of cross
section shape on shear resistance, and measured the deflection in the
middle of the beams then we compared these results with the
mathematical results and with results from other researchers, finally
we developed a relationship to determine shear capacity in high
strength concrete T beams.
