Research summary
تناول البحث عملية استخلاص التوتياء من الوسائط المستهلكة في الصناعة باستخدام حمض الكبريتيك كعامل هضم. تم تحديد الشروط المثلى لعملية الهضم بحمض الكبريتيك، حيث كان التركيز الأنسب 2 مول/ليتر، ودرجة الحرارة 50 مئوية، وزمن الخلط 60 دقيقة. بعد ذلك، تم ترسيب التوتياء من المحلول على شكل كبريتات التوتياء بإضافة الكحول الإتيلي. تم تطوير نماذج رياضية جديدة لتحليل البيانات التجريبية باستخدام حسابات القيمة الوسطية التربيعية، وتم التوصل إلى علاقات رياضية تحدد معاملات النماذج. أظهرت النتائج توافقاً جيداً بين البيانات التجريبية والنماذج الرياضية، مما يؤكد أهمية استخدام النمذجة في الدراسات الكيميائية التطبيقية.
Critical review
دراسة نقدية: يعتبر البحث ذو أهمية كبيرة في مجال استخلاص المعادن وإعادة تدويرها، خاصة في ظل التحديات البيئية والاقتصادية الحالية. ومع ذلك، يمكن توجيه بعض النقد البناء للبحث. أولاً، كان من الممكن تقديم مقارنة أكثر تفصيلاً بين فعالية حمض الكبريتيك والأحماض الأخرى المستخدمة في الدراسة. ثانياً، لم يتم التطرق بشكل كافٍ إلى التأثيرات البيئية المحتملة لاستخدام الكحول الإتيلي في عملية الترسيب. وأخيراً، كان من الممكن توسيع نطاق الدراسة لتشمل تطبيقات صناعية أخرى للتوتياء المستخلص، مما يزيد من القيمة العملية للبحث.
Questions related to the research
  1. ما هي الشروط المثلى لعملية هضم التوتياء باستخدام حمض الكبريتيك؟

    الشروط المثلى هي تركيز 2 مول/ليتر، درجة حرارة 50 مئوية، وزمن خلط 60 دقيقة.

  2. كيف تم ترسيب التوتياء من المحلول بعد عملية الهضم؟

    تم ترسيب التوتياء على شكل كبريتات التوتياء بإضافة الكحول الإتيلي إلى المحلول.

  3. ما هي الأهمية البيئية لاستخلاص التوتياء من الوسائط المستهلكة؟

    يساهم استخلاص التوتياء في تقليل التلوث البيئي الناتج عن التخلص من الوسائط المستهلكة، ويتيح إعادة استخدام التوتياء بشكل اقتصادي.

  4. ما هي الأدوات البرمجية المستخدمة في تحليل البيانات ورسم النماذج الرياضية؟

    تم استخدام برنامج فيجول بيسك لإيجاد ثوابت النموذج والمعطيات الإحصائية، وبرنامج ماتلاب لرسم الخطوط البيانية للنماذج الرياضية.

Hydrocarbon burning nowadays has a great part of the required energy consumed in the world, mainly in the transport vehicle engines, which seems to be the main source in the future. This urges us develop the fuel burning in different internal combust ion engines according to the environmental increasing requirements nowadays. The carbon fine-dust produced is the main source of the environmental pollutants, which could be considered as the main cause of cancer. Therefore our present paper deals with the way of carbon fine dust formation during fuel burning in engines and gives a mathematical model describing that complex method, and studying the different function affecting its formation, the aim is to find a way to develop the burning process in engines and increase its working and decrease the pollution produced.
Information extraction is the task of finding structured information from unstructured or semi-structured text. It is an important task in text mining and has been extensively studied in various research communities including natural language proc essing, information retrieval and Web mining. It has a wide range of applications in domains such as biomedical literature mining and business intelligence. Two fundamental tasks of information extraction are named entity recognition and relation extraction. The former refers to finding names of entities such as people, organizations and locations. The latter refers to finding the semantic relations between entities.
In our work, we chose to follow semantic transfer based approach. Our approach consists of two main phases. The first phase, Natural Language Analysis phase, aims to analyze the text and extract the required knowledge from it. In addition to the synt actic analysis results, one of the main outputs for this phase is a concept map which summarize the concepts of the related domain and the relationships between these concepts.
Industry is considered the main support of economical development in all around the world ، while Extractive industry in particular considered the main supporter of economical development in countries of Arabian peninsula since all elements of its are available. This study depend on uses some of statistics indexes to demonstrate the importance of industry in comparison with the other economical activity in the country of territory such as the rate size of industry، rate of density of industry and rate of industrial importance. This study shows that there are differences between industrial size and its density in Saudi Arabia. However، the existence of oil lead to take the first rank in industrial importance، United Arab of Emirates was taken the second rank، but Yemen and Oman were taken the last rank. For that reason the other countries of the territory should care of the industrial side and take the benefit from industrial countries experiences.
This research aims to define the reality of the Syrian industrial sector and analyze its contribution to the national economy, as the industry, with its various sections, is considered one of the basic economic pillars that contribute to bringing abo ut qualitative changes in the process of economic and social development. Jobs chances . The Syrian industries sector, with its various divisions, is one of the important sectors that contribute to achieving a great deal of development depending on strengthening the concept of economic independence for the state by dispensing with imports in addition to providing goods to the population. By studying the contribution of the Syrian industrial sector to the formation of the gross domestic product And the contribution of the Syrian industrial sector in the formation of the gross domestic product. The contribution of the industrial sector in the employment of the labor force. The contribution of the industrial sector to exports. Consequently, reaching a set of results that show the reality of the industrial sector and its contribution to the national economy, in addition to submitting a set of proposals that may contribute to overcoming the causes leading to its low performance in a manner that enables it to achieve the desired goals.
