...Show More Authors

تعد صناعة السمنت في العراق من اقدم الصناعات الحديثة واكثرها تطورا وتقدما ومن اقواها تاثيرا في الاقتصاد القومي. واذ توفر في صناعة السمنت العراقي كافة المستلزمات الناجحة من حيث توفر المواد الاولية والخبرات الفنية والتقنية واسواق ثابتة وراسخة محليا وعالميا فقد كان من المفروض ان يتم التوسع في هذه الصناعة، وان التخطيط لهذه الصناعة امرا ضروريا خاصة وان مادة السمنت هي احدى اهم المواد الرئيسة التي يؤثر توفرها بشكل كبير على انجاز المشاريع العمرانية والاقتصادية ومن هذا المنطلق فقد تم اعداد الدراسات لمستقبل هذه الصناعة من اجل النهوض بها وتطويرها وتوسيعها.

 وان هدف البحث هو التنبؤ بكميات انتاج السمنت العراقي للمدة المستقبلية (2003 - 2013) باستخدام افضل نماذج بوكس جينكنز الملائمة (B -J).

 وقد توصل البحث الى جملة من الاستنتاجات وهي: باستخدام طريقة بوكس جينكنز وجد ان السلسلة غير مستقرة وبذلك تم اخذ الفرق الاول بهدف تحقيق الاستقرارية. وكذلك من سلوك معاملات الارتباط الذاتي والجزئي استنتجنا انه امكن تحديد واختيار النموذج الملائم لتمثيل السلسلة، حيث كان النموذج الملائم هو  ARIMA (2, 1, 0) وكذلك وجدنا ان الحدود الدنيا للتنبؤ قد تكون سالبة، وهذا مما يدل على انه في حالة الحاجة الماسة الى هذه المادة فأن الانتاج المحلي قد لا يكفي لذلك يلجأ البلد الى سد النقص الحاصل عن طريق الاستيراد.

 اما التوصيات فهي: نوصي باعتماد النموذج الذي تم التوصل اليه في طريقة بوكس – جينكنز بغية الاستفادة منها في التخطيط والتنبؤ للفترات القادمة. وكذلك نوصي الشركة العراقية لانتاج السمنت ان تعتمد على القيم التنبئية المستخرجة من تطبيق النموذج برسم خططها المستقبلية. وكذلك ان البلد في الوقت الحالي بحاجة الى عملية اعمار واسعة لذلك نوصي بزيادة الطاقة الانتاجية من هذه المادة لغرض سد النقص الحاصل.

Using tobacco leaves as adsorbent for the orange-g dye removal from its aqueous solutions
...Show More Authors

The removal of commercial orange G dye from its aqueous solution by adsorption on tobacco leaves (TL) was studied in respect to different factor that affected the adsorption process. These factors including the tobacco leaves does, period of orange G adsorption, pH, and initial orange G dye concentration .Different types of isotherm models were used to describe the orange G dye adsorption onto the tobacco leaves. The experimental results were compared using Langmuir, and frundlich adsorption isotherm, the constants for these two isotherm models was determined. The results fitted frundlich model with value of correlation coefficient equal to (0.981). The capacity of adsorption for the orange G dye was carried out using various kinetic models

Islam's position on freedom according to John Stuart Mill
...Show More Authors

The issue of freedom is the most prominent and distinctive issue of Western thought, which it reached after a long struggle. The English thinker John Stuart Mill is considered the most prominent Western thinker who elaborated on the issue of freedom, until his ideas on the issue of freedom became the semi-final formula for issues of freedom in Western thought, which revolve in their entirety on The individual has complete freedom as long as it does not harm others, and this freedom is controlled by law.

And if the freedoms he offered were not considered an achievement in Western thought; Freedom in Islam is a central and fundamental issue, and the details of freedoms in Islam have not been accomplished by anyone, but rather came

Improving Biogas Production from Rice Husk Waste by Mixing with Pomegranate peels Waste by using Anaerobic Digestion
...Show More Authors

Biogas is one of the most important sources of renewable energy and is considered as an environment friendly energy source. The major goal of this research is to see if rice husk (Rh) waste and pomegranate peels (PP) waste are suitable for anaerobic digestion and what effect NaOH pre-treatment has on biogas generation. Rice husk and pomegranate peels were tested in anaerobic digestion under patch anaerobic conditions as separate wastes as well as blended together in equal proportions. The cumulative biogas output for the blank test (no pretreatment) was 1923 and 2526 ml, respectively using a single rice husk (Rh) and pomegranate peel (PP) substrates. The 50% rice husk digestion and 50% of pomegranate peels for blank test gave the result 224

Esterification of Free Fatty Acid with High Chain Alcohol for Biodiesel Production Using Semi-Batch Reactive Distillation
...Show More Authors

The esterification of oleic acid with 2-ethylhexanol in presence of sulfuric acid  as homogeneous catalyst was investigated in this work to produce 2-ethylhexyl oleate (biodiesel) by using semi batch reactive distillation. The effect of reaction temperature (100 to 130°C), 2-ethylhexanol:oleic acid molar ratio (1:1 to 1:3) and catalysts concentration (0.2 to 1wt%) were studied. Higher conversion of 97% was achieved with operating conditions of reaction temperature of 130°C, molar ratio of free fatty acid to alcohol of 1:2 and catalyst concentration of 1wt%. A simulation was adopted from basic principles of the reactive distillation using MATLAB to describe the process. Good agreement was achieved.

An induction of Undecylprodigiosin Production from Streptomyces coelicolor by Elicitation with Microbial Cells Using Solid State Fermentation
...Show More Authors

Red pigmented undecylprodigiosin produced by Streptomyces coelicolor (A3)2 is a
promising drug owing to its characteristics of antibacterial, antifungal,
immunosuppressive and anticancer activities. The culture of S. coelicolor in liquid
medium produces mainly the blue pigmented actinorhodin and only low quantities of
undecylprodigiosin. From an industrial point of view, it is necessary to find a strategy to
improve undecylprodigiosin production. The present study provides evidence that
cultivation of S. coelicolor on solid substrate resulted in a reversal in this pattern of
antibiotic production as the production of undecylprodigiosin was significantly increased
and actinorhodin was completely suppressed. Four di

Calculating Production Rate of each Branch of a Multilateral Well Using Multi-Segment Well Model: Field Example
...Show More Authors

Multilateral wells require a sophisticated type of well model to be applied in reservoir simulators to represent them. The model must be able to determine the flow rate of each fluid and the pressure throughout the well. The production rate calculations are very important because they give an indication about some main issues associated with multi-lateral wells such as one branch may produce water or gas before others, no production rate from one branch, and selecting the best location of a new branch for development process easily.                                &nbsp
