In this research we studied the corrosion rate changes of iron samples which are not galvanized in the laborators ( laboratorsies of the faculty of science) and in nature (on the beach of the high-institute sea- research in Lattakia) The Inula extracts were choosen as a plant inhibitor to cover the iron samples and protect it . because this plant is well known in the Coastal area, also it,s very cheap and easy to find and has good anti oxidation properties. The best conditions for (Inula-seawater) extract were : (PH=7 , time =24 hours , concent ration = 10%). The studied iron samples were treated with the ( inula-seawater) extract in the same previous conditions and we studied the corrosion rate changes for those samples and the affectivity of the inhibitor for them. The results were compared in each stage with other samples that were not treated . the treatment and after it were as follows: The velocity of the corrosion in the iron samples (before the treatment with the extract) in 120 days: - in the laboratory tanks was 0.78 mg/cm2 .day, but after the treatment was 0.23 mg/cm2.day -in the drizzle area was 0.80 mg/cm2.day, but after the treatment was 0.47 mg/cm2.day -in the waves area was 0.75 mg/cm2.day , but after the treatment was 0.41 mg/cm2.day - in the depth area was 0.79 mg/cm2.day , but after the treatment was 0.21 mg/cm2.day.

Research summary
تناول البحث دراسة حماية الحديد من التآكل في البيئة البحرية باستخدام مستخلص نبات الطيون كمانع تآكل نباتي. تم إجراء التجارب مخبرياً وميدانياً على شاطئ البحر في مدينة اللاذقية. اختير مستخلص نبات الطيون نظراً لتوفره في البيئة الساحلية وسهولة الحصول عليه، بالإضافة إلى خواصه المضادة للأكسدة. حددت الشروط المثلى للمستخلص (pH=7، الزمن=24 ساعة، التركيز=10%). أظهرت النتائج أن معدل سرعة التآكل للعينات المعالجة بالمستخلص كان أقل بكثير مقارنة بالعينات غير المعالجة، مما يدل على فعالية المستخلص في تقليل التآكل. تم قياس معدل سرعة التآكل في مناطق مختلفة مثل منطقة الرذاذ، منطقة الأمواج، ومنطقة العمق، وكانت النتائج متوافقة مع التوقعات حيث كانت فعالية المستخلص أعلى في المناطق ذات الأكسجين المنخفض. توصلت الدراسة إلى أن استخدام مستخلص نبات الطيون يمكن أن يكون بديلاً اقتصادياً وبيئياً عن المواد الكيميائية التقليدية المستخدمة في منع التآكل.
Critical review
دراسة نقدية: على الرغم من أن البحث يقدم حلاً بيئياً واقتصادياً لمشكلة التآكل في البيئة البحرية، إلا أن هناك بعض النقاط التي يمكن تحسينها. أولاً، لم يتم دراسة تأثير المستخلص على أنواع أخرى من المعادن، مما يحد من تطبيق النتائج. ثانياً، لم يتم التطرق إلى تأثير العوامل البيئية الأخرى مثل درجة الحرارة والرطوبة على فعالية المستخلص. ثالثاً، الدراسة اقتصرت على فترة زمنية محدودة (أربعة أشهر)، مما يجعل من الصعب تقييم فعالية المستخلص على المدى الطويل. أخيراً، يمكن تحسين منهجية البحث بإجراء تجارب ميدانية في بيئات بحرية مختلفة للحصول على نتائج أكثر شمولية.

We studying in this research the reaction with Zinc sulphate in an aqueous solution by physical - chemical method in presence of Succinic Acid , and determined compounds which are formed in this solution and we calculated of it formation the const ants. After we used these electrolytes in plating by Zinc , that is by electro precipitation of this metal on the solid electrodes (steel, copper) so that we definite the best of these electrolytes for galvany and the set necessary conditions for its use.
The aim of this study is to highlight the potential use of marine algae as well as polypropylene for the removal of crude oil from surface seawater. The determination of optimal sorption time and sorption capacity of the materials in oil/water bath and oil bath without water in presence of three oils of different viscosity were investigated. The capacity of oil removal from seawater was related to structure and surface properties as well as oil amount and oil properties especially, its viscosity. The results revealed that the extension of absorption time does not influence absorption capacity of the examined sorbents in presence of both oils of low and middle viscosity (LV and MV). Nevertheless, the sorption capacity was increased by extending the absorption time to 30 min. For high viscose oil (HV). The sorption capabilities of Enteromorpha exceeded those observed for all of the other algae, while polypropylene fiber showed the highest capacity. Overall, the sorption capacity of the studied sorbents increased with increasing oil viscosity. The absorption capacities of studied materials in the oil bath and oil/water bath were comparable. The results suggested that substitution of synthetic oil sorbents used in Syria by marine algae is possible in oil removal, which have relatively high sorption capacity.
The research aims to reach fuel conservation opportunities and environment Protection while heating the water, by comparing the most common uses of primary and secondary energy carriers in our country . For example, water heating using electricity ge nerated by fuel oil and gas, or the direct use of gas and diesel oil for water heating. The coast of heating the water domestic uses was calculated by various ways, in order to find a low coast method and to avoid environmental damage. In this research ,the conservation of primary energy for water heating while using gas and diesel oil boilers, was 4 times larger compared to the use of electricity generated by gas and fuel oil .As a result, the coast of water heating using gas burner was 4 times lower, while the coast of water heating using gas boiler was 10 times lower, compared to the coast of electricity heating method. this research also showed, that the use of gas fuel , is the best water heating method, concerning fuel conservation and environment Protection.
this paper highlights the role NGOs played in developing these treaties and conferences, setting an example on how to protect the environment and stop its deterioration on both national and international levels and find solutions to the problems and limit them.
This survey aims at recognizing the reality of the social responsibility and protecting the environment in Al-Faris Firm for pharmaceutical industries in Syria besides demonstrating the relations between the adoption of the social responsibility b y this company and its impact on environmental protection. this falls within the scope of the research question which can be summarized as follows: what is the impact of adopting corporate social responsibility at al-Fares Company for Pharmaceutical Industries in Syria on the protection of the environment?
