In this paper, the thermal performance of the doctors and nurses housing building in Aleppo walls, consisting of the hollow blocks with inside styropor sheet and compare it with a wall consisting of hollow blocks with eternal continuous insulating styropor layer and the effect of adding continuous insulating layer on the existing walls. The study showed that the use of the block with inside styropor slice was not useful regarding the thermal behavior and causing large and intense thermal bridges generation. However the use of block with continuous styropor layer made the temperature distribution more uniform and reduced the energy flux by 36.7-70%.

Research summary
تتناول هذه الورقة البحثية تأثير أنظمة مواد البناء المختلفة على الأداء البيئي للمباني، مع التركيز على الأداء الحراري للجدران. تم دراسة جدران مبنى سكن الأطباء والممرضات في جامعة حلب، حيث تم مقارنة جدران مكونة من بلوك مغرغ يحتوي على شريحة ستريوبور غير مستمرة بجدران تحتوي على طبقة عزل مستمرة. أظهرت النتائج أن استخدام البلوك مع شريحة الستريوبور غير المستمرة يؤدي إلى جسور حرارية كبيرة، بينما استخدام طبقة عزل مستمرة يقلل من تدفق الطاقة بنسبة تتراوح بين 36.7% و70%. كما تم دراسة تأثير إضافة أنظمة عزل وزجاج على الجدران، حيث تبين أن إضافة بولي يوريثان بسماكة 2 سم مع زجاج مغرد للنوافذ يوفر 13.6% من الوقود، وتزداد النسبة إلى 26.3% عند استخدام زجاج مزدوج و29.8% عند زيادة سماكة العزل إلى 3 سم. توصي الدراسة بعدم استخدام شريحة الستريوبور داخل البلوك واقتراح استخدام طبقة عزل مستمرة خارجية لتحقيق أفضل أداء حراري واقتصادي.
Critical review
دراسة نقدية: تقدم هذه الورقة البحثية تحليلاً شاملاً ومفصلاً لتأثير أنظمة مواد البناء على الأداء البيئي للمباني، وهو موضوع ذو أهمية كبيرة في الوقت الحالي. ومع ذلك، يمكن الإشارة إلى بعض النقاط التي قد تحتاج إلى تحسين. أولاً، الدراسة تعتمد بشكل كبير على النمذجة العددية، وكان من الممكن تعزيز النتائج بإجراء تجارب ميدانية إضافية للتحقق من صحة النماذج. ثانياً، لم تتناول الدراسة بشكل كافٍ تأثير العوامل البيئية الأخرى مثل الرطوبة والرياح على الأداء الحراري للجدران. أخيراً، كان من الممكن تقديم تحليل اقتصادي أكثر تفصيلاً يشمل تكاليف الصيانة والتشغيل على المدى الطويل.

the importance of research to define the importance of the restoration to preserve the identity of the country and its heritage and authenticity as well as for the restoration of some of the buildings came to show contemporary form processions of progress and development that we are witnessing in addition to the development of systems and controls set standards and methods of restoration, protection and maintenance in order to direct the business in the right direction and organize repairs to stop the dangers arising wrong to intervene and factors demise and the demise of heritage buildings, which are often caused by personal interpretations resulting from the absence of references and standards pertaining to restoration and especially in our country, in addition to the non-observance of international standards for restoration.
The aim of this study, the development of systems and controls set standards and methods of restoration and protection and maintenance to operate this business in the right direction and straighten restoration goals in the right direction away from reconstructive mistakes that we are experiencing as a result of the absence of references and standards reconstructive and especially in our country.
The environmental culture is often absent from the minds of investors. Thus, devoted architect efforts in the field of production form،Without regard to the extent influenced by the concepts of sustainability. As well as the impact of production on t he environment negatively. We find architectural products require high operating costs. Because of exaggeration in the use of materials may not be environmentally compatible. The architect alone is not responsible. There is also a lack of appreciation from the community. Or interest in the traditional entrance in Architecture, (Use of traditional solutions in climate treatment( In addition to the lack of real environmental legislation to deter it. It is imperative to make binding for buildings and tourist complexes existing environmental procedures. And adherence to the study is necessary to reach the tourism respectful of the environmental standards. Reduction of the consumption of resources and on the design process and the level of sustainable tourism level. This paper deals with the process and presents the basic steps that you must follow in resolving such buildings. And through monitoring some recreational facilities and tourist complexes around the world. It explains the general effects that led to the development of this type of buildings. It also includes some of the foundations and the general principles and standards-setting process to adjust the design and architectural sketch. In order to address such buildings academically in Syria.
The behavior of the basaltic shear diaphragms of the remaining buildings of ancient times was investigated as experimental research,and its resistance to natural factors and horizontal loads resulting from wind and earthquakes,to take advantage of them in the maintenance of modern buildings,which are associated with floors and beams as horizontal shear diaphragmsIn the hot and cold areas of the African continent, Asia and other similar areas,to replace the reinforced concrete shear diaphragms,and metal shear diaphragms that lose their resistance to the above factors. When the buildings are inspected, the vertical and slanted slits resulting from the side loads are placed,it was found that the appearance of the cracks related to the hardness of the shear diaphragm section, the basalt stone specifications and the design of the shear diaphragm base.The research was conducted to determine the durability, water permeability and resistance to pressure and tensile strength of basalt stone samples used in historic stone buildings and their location in laboratory methods.Horizontal loads resulting from seismic intensity were determined on the front of the building at the tile level according to international requirements and specifications.The method of calculating the basaltic shear diaphragms was applied by applying arithmetic to build a basalt stone from several floors and a basement, taking into account the characteristic resistance of basalt, depending on its density from pressure and stretching and basalt stone in calculating.
The application of this research was implemented at the laboratories of Food Science Department, Agriculture College, Damascus University in order to investigate the effect of different ratios of added oil upon the rheological, chemical and microb ial characteristics of mayonnaise. The traditional mayonnaise was made from fresh egg, vinegar, salt, mustard, citric acid and corn oil at 70% ratio, to be used as a standard. Two changes in the oil ratio: 40% and 50% were applied for obtaining lower oil mayonnaise, with fewer calories (Diet). The influence of adding Xantan gum as a substitute to oil reduction, on the properties of final product was also investigated. Results showed that the addition of Xantan gum at 1.5% was necessary to complement the reduction in the added oil. The results also confirmed that reduction in the added oil of the diet mayonnaise led to reduction in viscosity and firmness when compared with the standard mayonnaise.
