Orange fruits contain many materials such as oils in seeds which have biological and nutritional values, due to that, physical and chemical properties of orange seed oil (OSO) have been determined, which extracted from two samples collected from two areas (Al-ssisanyah and Al-jma'ashyah) which are different in environmental factors.

Research summary
تتناول هذه الدراسة الخصائص الفيزيائية والكيميائية ومحتوى الحموض الدسمة لزيت بذور برتقال الفلانسيا (Citrus sinensis) في محافظة طرطوس. تم جمع عينات من منطقتين مختلفتين بيئيًا (السيسنية والجمعاشية) وتم تحليلها باستخدام عدة أجهزة وطرائق. أظهرت النتائج أن الكتلة الحجمية للزيت تراوحت بين 0.870 و0.880 غ/مل، واللزوجة الحركية بين 30.61 و31.62 ملم²/ثا، وقرينة الانكسار بين 1.4690 و1.4691، والتوتر السطحي بين 25.19 و26.68 ن/م، ونقطة التجمد بين 6.2 و7.1 درجة مئوية. كما تم تحديد قرينة الحموضة وقرينة التصبن وقرينة الإستر وقرينة اليود ومحتوى الغليسيرول. باستخدام تقنية GC-MS، تم تحديد أن حمض النخيل، وحمض الزيت، وحمض الكتان، وحمض الشمع هي الحموض الدسمة الأكثر وجودًا في الزيت. أظهرت الدراسة أن زيت بذور البرتقال يحتوي على خصائص مشابهة لبعض الزيوت النباتية الأخرى، مما يجعله مناسبًا للاستخدامات الغذائية والطبية والصناعية.
Critical review
دراسة نقدية: تعتبر هذه الدراسة خطوة مهمة في فهم الخصائص الفيزيائية والكيميائية لزيت بذور البرتقال، ولكن هناك بعض النقاط التي يمكن تحسينها. أولاً، كان من الأفضل توسيع نطاق العينات لتشمل مناطق أخرى لضمان تعميم النتائج. ثانيًا، لم يتم التطرق بشكل كافٍ إلى تأثير العوامل البيئية المختلفة على خصائص الزيت، وهو ما يمكن أن يكون له تأثير كبير على النتائج. ثالثًا، كان من المفيد تضمين مقارنة أوسع مع زيوت نباتية أخرى لتقديم صورة أكثر شمولية عن مكانة زيت بذور البرتقال بين الزيوت النباتية. وأخيرًا، كان من الممكن تقديم توصيات أكثر تحديدًا حول كيفية استخدام هذا الزيت في الصناعات المختلفة بناءً على النتائج.

Orange fruits are characterized at harvesting with physical and sensory properties determine consumer acceptance and in order to identify these characteristics and vulnerability storage and irradiation conditions, Valancia orange fruits were subje cted to gamma irradiation at doses of 0.0, 0.5, 1.0, and 1.5 kGy using gamma 60Co irradiator facility. Fruits were kept in a refrigerator for 18 weeks. Results indicated that physical and sensory properties of Valencia orange fruits were affected by storage time and irradiation. The overall color differences were increased and the firmness of fruits and skin were decreased. The used doses of gamma irradiation increased the overall color differences of fruit skin. Whereas the fruit firmness, and the sensory properties (aroma, color, test and firmness) of irradiated Valencia orange fruits were decreased.
Syria has produced cotton oil with large quantity like many other countries.This position provides an impetus to develop oleochemical industries, such as: fatty acids, fatty methylester, and fatty alkyl ester. These products can be sulfonated with SO٣ or HSO٣Cl. As a result, the obtained products have interesting properities due to their good detergency, lower sensitivity to water hardness, rapid degradability, and good skin mildness properties. Therefore, they can be used when mixed with other detergents or soaps for house hold purposes.
The main aim of this study was to determine the effect of slope position on some soil physico-chemical properties .The study was conducted on a pine forest soil , Tartous. Soil samples were collected from top , mid and bottom slope positions at hor izon- A and C of top and mid slope positions and at horizon A,(B)and C of bottom slope positions . Results showed a significant difference among the physico-chemical properties of top , mid and bottom slope soils . Bulk density of the top - slope (1.34 gcm-3) was the highest followed by mid ( 1.31 gcm-3) and bottom slopes (1.27 g cm-3) .Conversely ,Organic matter content (2.86%) ,electrical conductivity EC(0.20mmos/cm) , calcium(28.3 meq/100g) , magnesium(6.80 meq/100g) , Potassium (0.21 meq/100g), Soil pH ( 7.95) , clay content (38.43 %) and silt content (34.70%) were the highest at bottom slope followed by mid and top- slopes , respectively . Soil A and C horizon of top and mid slope positions and A ,(B)and C horizons of bottom slope positions were also significantly different in their physical and chemical properties . Horizon A had the highest organic matter ,electrical conductivity , calcium , magnesium , silt contents and lower bulk density,CaCO3, sand contents than both the (B) and C horizons of bottom slope and the C horizon of top and mid slope .The deterioration in physico-chemical properties of top slope as compared to mid and bottom slopes and that of A horizon as compared to C horizons were presumed to be due to past soil erosion effect that removed the finer soil particles including soil organic matter and other plant nutrient.
The research aims to identify incoming fatty acids in the composition of both the Syrian domestic oil extracted from the seeds of Nigella sativa, fenugreek, borage and Rocket , using gas chromatography GC, as the goal to identify some of the most i mportant physical properties ( density and refractive index ) and chemical ( Iodine number and saponification number ) utmost to improve and develop the Syrian varieties of the studied oils. Search Results showed that borage oil contain the highest proportion of the Poly unsaturated fatty acids ( 81.5% ) PUFA and the highest percentage of gamma -linolenic acid ( 14.4% ) GLA, and it was for each of Nigella sativa oil and oil fenugreek close by percent's of ( 60.89%-60.95% ) PUFA, and overall mono unsaturated fatty acids ( 33.89%- 28.19% ) MUFA and linoleic acid ( 60.71%-58.92% ) LA has the enjoyment of the highest value oil ring of oleic fatty acid ( 26.72% ), while oil Rocket had the highest values ( 79%) MUFA so different from the rest of the studied oils. The results of this research clearly compatible with the results of global studies at the same oils.
This research was performed to study the effect of sewage water on the surface water of the Addelbeh Valley stream, and groundwater on both sides of the stream in Tartous Cement Factory area. Water samples were taken from the factory water outlet and Addelbeh Valley water to study the content of pollutants. We also took groundwater samples from selected wells on both sides of the waterway in the studied area. We repeated that process every two months for a full hydrological cycle from July 2013 to May 2014. We found a great increase in content of the industrial drainage water include oils and heavy metals especially iron, copper and zinc. For example: iron concentration in sewage water exceeded 150 mg/l in all samples. Besides sewage water and stream water contained high concentrations of ammonia and nitrite versus low concentration of nitrate, unlike water wells samples. The study revealed increased EC and salts concentration markedly in wells water due to its adjacency to the sea.
