Lubricant type and concentration play a very important role on metalic powder characterestics. This research presents the outcomes of an experimental investigation on the effect of lubricant type and content to the green compressibility, and strength of green pieces produced by adding different amounts (0.5,1,1.5)% and different types (zinc stearate,graphit,poley phinil alcohol) of lubricant to the iron powder, and mixing them for one hour in V shape blender ,then pressing them to different densities (75,80,85)% out of the the theoretica density.

Research summary
تناقش هذه الدراسة تأثير المواد المزيتة على متانة وانضغاطية العينات الخضراء المصنعة من المساحيق الحديدية. تم استخدام ثلاث مواد مزيتة هي استيرات الزنك، الغرافيت، وبولي فينيل الكحول بنسب مختلفة (0.5%، 1%، 1.5%)، وتم خلطها مع مسحوق الحديد لمدة ساعة في خلاط على شكل حرف V، ثم كبسها عند درجة الحرارة العادية إلى كثافات مختلفة (75%، 80%، 85%) من الكثافة النظرية للحديد. أظهرت النتائج أن الغرافيت يعطي أعلى انضغاطية ولكن متانته منخفضة، بينما يعطى كل من استيرات الزنك وبولي فينيل الكحول نفس الانضغاطية تقريباً. وتكون متانة استيرات الزنك هي الأعلى عند النسبة المنخفضة (0.5%)، لكن عند نسب أعلى تكون المتانة الخضراء عند استخدام بولي فينيل الكحول هي الأعلى.
Critical review
تعتبر هذه الدراسة مفيدة في فهم تأثير المواد المزيتة على خصائص العينات الخضراء المصنعة من المساحيق الحديدية. ومع ذلك، يمكن تحسين الدراسة من خلال تضمين تحليل أكثر تفصيلاً للآليات الكيميائية والفيزيائية التي تؤدي إلى التغيرات في المتانة والانضغاطية. كما يمكن تحسين الدراسة من خلال إجراء تجارب إضافية تشمل مواد مزيتة أخرى ونسب مختلفة للحصول على صورة أكثر شمولية. بالإضافة إلى ذلك، يمكن تحسين العرض البصري للنتائج من خلال استخدام رسوم بيانية أكثر توضيحاً.

In this research, It has been studied the effect of compaction pressure on the final roughness for the top and down surfaces for the green compacts that manufactured by meal powder technique and it has been studied also the effect of piston veloci ty (compaction velocity) on the final roughness for the same two surfaces. The results present that the curved for the top surface roughness is completely decreasing and as the pressure has increased, the value for roughness has reduced and the mean roughness (Ra) has very close values, where these values have made curve from second degree and opposite relationship. The results were same for the down surfaces but with different variations.
The changes in green peas, processed by using freezing and bleaching were compared with their chemical composition (moisture, ash, sugar, fat). Effect of freezing and bleaching processes of green peas on the ascorbic acid, total phenolic compounds ,and antioxidant activity were investigated. Significant changes were occurred between fresh and processed peas with regard to their content of ascorbic acid, total phenols, and antioxidant activity as measured by DPPH. Vitamin C content reduced to 65% in frozen peas and to16% in bleaching peas. The decreased in total phenols was less, being 150mg/100g fw in fresh peas reduced to 140 mg/100g fw in bleaching peas, and reached 120mg /100g fw in freeze peas. These changes have been reflected significantly (P<0.05) in antioxidant activities. Storage of green peas, frozen or boiled peas, for 8 weeks, resulted in significant loss in vit C, antioxidant activity(P<0.05).
The research was conducted during the growing season in 2013- 2014 in Bssiren Hama. In a split- plot design: the varieties were main plots (asgro, rama, Muncipal) and the sowing dates were subplots (15\11;30\11;15\12 and 30\12) and the densities we re subplots (20 plant\m2, 13.33 plant\m2). The early planting went to Significant increase in the days to germination, long time of fruit; the number of days to flowering and the number of days to fruiting; Plant height; Number of branches plant ; weight of pod; number of pods plant; dressing percentage; Yield of green pods plant and Yield of green pods. While the high density was observed Significant increase in the Plant height; Number of branches plant; weight of pod; number of pods plant; and Yield of green pods plant, while the low density was observed Significant increase in the Yield of green pods. The Asgro variety was obtained at Rama and Muncipal varieties in the number of branches plant; number of pods; Yield of green pods plant and, while the Rama variety was obtained by the plant height, and non- significant results were found among varieties by the weight of pod. The positive results also showed in the interaction among factors.
Sustainability and health care building are two important issues, which contain many of topics are very in composition, Sustainability is a thought aimed at achieving compatibility between human needs and the data of surrounding environment and w ell-employed, taking into account the constants, geographic, climatic , economic and technological development, while we find that under the technological age and globalization the Common design for hospital has focused on the functional aspect, which deals entirely with the hospital as a place to treat only, which creating problem of the discrepancy between the functional treatment design which requires strictly control in the internal environment in many of hospital spaces such as operating rooms. etc. while patient rooms need environmental conditions more humane and interaction with the external environment ,from this mix came the idea of green hospitals , which aims to Integrate the idea of therapy and healing at the same time within the new hospital installation .
This study aims to clarify the ability of Syrian companies to improve their performance through adoption of green accounting as a marketing concept and its impact on market share. The study focused on the components and obstacles of environmental knowledge for application of green accounting and its impact on the marketing performance of the company. The researcher used the descriptive approach in the research community (Banias Oil Refining Company), using a survey that has been distributed amongst workers in the company, then the researcher analyzed the survey results by the Statistical Package for the Social Sciences (SPSS). The research concluded the following findings: Environmental knowledge among workers is not at the required level, and this is what hampers the application of green accounting in the academic concept Basically, in addition to having a lot of obstacles that have limited the success in the application of green accounting and that reflected in turn on the marketing performance of the company.
