This study ains for the ability of using granite waste emerged by sawing granite in Syria, which is considered as a negative effect on the environment , which pollutes the air , people, animal and planit. The chemical composition of granite waste was defined and it was clear that it is same as the chemical composition of glass . so we did this work by transforming the waste caused by granite sawmills to the glassy state. The preparation for the glassy states were done py two methods , the first by adding sand and sodium carbonate and second by adding borax and sodum cab ronate and the heattreatment was done at (900-1000 c) . The assurance of getting the glassy state through the XRD measure to the resulted samples was done . and the chemical composition of glass resulted by alkaline melting way was identified , then doing the chemical analyses needed to signify the percentage of oxides of the elements and in the second step of the worke , they have made tests on the resulted glass (its intensity, its resistance of acids and bases ). The decrease of intensity was noticed by the increase of silica concentration , sodium oxide and borates oxide , and it was noticed the increase of the resistance to the acids and alkalis by the increase of silica concentration and sodium oxide , but through adding the borates, the result was a glass less resistant to the acids and bases .

Research summary
تهدف هذه الدراسة إلى استكشاف إمكانية تحويل نفايات الغرانيت الناتجة عن مناشر الغرانيت في سوريا إلى حالة زجاجية، وذلك لتقليل تأثيرها السلبي على البيئة. تم تحديد التركيب الكيميائي لنفايات الغرانيت ووجد أنه مشابه للتركيب الكيميائي للزجاج. تم تحضير الأطوار الزجاجية بطريقتين: الأولى بإضافة الرمل وكربونات الصوديوم، والثانية بإضافة البوراكس وكربونات الصوديوم، ومعالجتها حراريًا عند درجات حرارة تتراوح بين 900 و1000 درجة مئوية. تم التأكد من الحصول على الطور الزجاجي باستخدام قياسات XRD وتحليل التركيب الكيميائي للزجاج الناتج. أظهرت النتائج أن زيادة نسبة السيليكا وأكسيد الصوديوم تؤدي إلى نقصان الكثافة وزيادة المقاومة للحموض والأسس، بينما إضافة البوراكس تؤدي إلى زجاج أقل مقاومة للحموض والأسس. توصي الدراسة باستخدام نفايات الغرانيت في صناعة الزجاج ودراسة تحسين خواص الزجاج بإضافات أخرى.
Critical review
دراسة نقدية: تعتبر هذه الدراسة خطوة هامة نحو الاستفادة من نفايات الغرانيت وتحويلها إلى مواد ذات قيمة اقتصادية، مما يساهم في تقليل التلوث البيئي. ومع ذلك، يمكن تحسين الدراسة من خلال توسيع نطاق التجارب لتشمل أنواع أخرى من النفايات الصناعية. كما يمكن تعزيز الدراسة بإجراء تجارب ميدانية لتقييم الأداء الفعلي للزجاج المنتج في تطبيقات صناعية مختلفة. بالإضافة إلى ذلك، يمكن توسيع البحث ليشمل دراسة تأثير إضافة مواد أخرى لتحسين خصائص الزجاج المنتج، مثل مقاومة الصدمات الحرارية والميكانيكية.
Questions related to the research
  1. ما هي الطرق المستخدمة لتحويل نفايات الغرانيت إلى حالة زجاجية؟

    تم استخدام طريقتين: الأولى بإضافة الرمل وكربونات الصوديوم، والثانية بإضافة البوراكس وكربونات الصوديوم، ومعالجتها حراريًا عند درجات حرارة تتراوح بين 900 و1000 درجة مئوية.

  2. ما هي الفوائد البيئية لتحويل نفايات الغرانيت إلى زجاج؟

    تحويل نفايات الغرانيت إلى زجاج يقلل من التلوث البيئي الناتج عن هذه النفايات، حيث يتم تقليل تلوث الهواء والماء والتربة، مما يساهم في حماية الصحة العامة والبيئة.

  3. كيف تؤثر إضافة البوراكس على خصائص الزجاج المنتج؟

    إضافة البوراكس تؤدي إلى إنتاج زجاج أقل مقاومة للحموض والأسس مقارنة بإضافة الرمل وكربونات الصوديوم، وذلك بسبب تأثير أكسيد البور على التركيب الكيميائي للزجاج.

  4. ما هي التوصيات التي قدمتها الدراسة لتحسين خصائص الزجاج المنتج؟

    أوصت الدراسة باستخدام نفايات الغرانيت في صناعة الزجاج ودراسة تحسين خواص الزجاج بإضافات أخرى، وكذلك البحث في استخدام نفايات صناعية أخرى مثل نفايات الرخام والأحجار الكلسية.

Humans started to produce the bread for Thousands years ago; they used to prepare the dough by using fermented dough which left for many days before used, so that this fermented dough has been prepared from dough fermented by aerobic microorganisms w hich can attack the milling wheat. Recently the Bekar’s yeast Saccharomyces cerevisiae produced in variable type's liquid, dry and soft which used in preparation of dough. The high cost of yeast production and limited quantity in the emergency and catastrophe conditions and difficulties in delivery to far away places lead to study the production of fermented sourdough instead of soft yeast completely or reduce its quantity relatively. Many kinds of fermented sourdough have been produced; liquid with moisture content 75%, normal density with moisture content 55% and high density with moisture content 47%, the fermentation's force and rise's force for their different value have been determined which ranged from 3% to 15%. The results investigated that production of dough from fermented sourdough 3%, 5%, 7%, 9% and 11% produced fermented dough with metabolic productions, which produced Arabic bread without significant changes in characteristics compared to the bread which produced by using 2% soft yeast.
The research focuses on finding planning methods based on measuring and monitoring the basic indicators of internal combustion engines (Diesel engines) in order to determine the critical case of the engines, which determines the expected time for t he engine or for some of its basic parts to be sent for comprehensive maintenance. The wear ratio of one of the basic components of the engine was also determined, we also chose the diameter of the cylinder and the corrosion that happens to it in order to determine the engine's lifetime and determine the moment when the engine should be sent for comprehensive maintenance. By observing a large number of engines put in repair in the industrial area in Lattakia, which are 30 engines of different types of diesel and gasoline, and with different capacities, it was noticed that about 15% of these engines were not exploited and invested the entire work period designed for them. Also it was noticed that 20% of them have stopped working because of the severe corrosion of parts, components and mechanics of these engines, which led to their damage and their inability to do their work on a regular basis. This has contributed to increased consumption of fuel and Lubricating materials, which causes damage to the national economy. The proposed planning method for determining the critical case of the engine when comparing the schematic results with the practical results of the engines has proved its efficiency and accuracy with an error rate of no more than 6% This allows it to be applied and adopted as an effective way to determine the actual lifetime of the engine and compare it with the life time of investing the engine mentioned in the manufacturer's catalogs when operating the engine under normal conditions.
This research aims to find the necessary conditions for the existence of the dark soliton solution to the Vakhnenko-Parkes equation with time dependent coefficients and with power law nonlinearity by using the solitary wave ansatz method. The value o f the power law nonlinearity parameter is determined. The results show that the used method is efficient to obtain this kind of solutions for the nonlinear partial differential equations.
The study was aimed to the determine the types of medical wastes produced by hospitals and having clearly panorama picture on the reality of management of medical wastes in some hospitals in Hama govern ate and the methods of treatment and sugges ted the suitable solutions and safely environmentally to manage these wastes according the results the mentioned research.
We offer in this research study of the probability density function of a continuous random variable. Where we have to reached to results that show the oneness of the general shape of this function when it is linear or quadratic, as we came up to the general formula for this function for each of the above two cases. It was clarified the necessary and sufficient conditions of a linear and quadratic function to be, a continuous probability density function.
