جمعت 80 عينة من الشنكليش عشوائياً بمعدل 5 إلى 12 عينة من مناطق مختلفة مـن محافظـات القطر العربي السوري خلال عام 2003 -2004 بمعدل وزني مقداره 400 غرام لكل عينة. أجريت علـى هذه العينات اختبارات العد الكلي للحمولة الميكروبية (فطور و خمائر و جراثيم)، ثم عزلت و عرفت الفطور المفرزة لسموم الأفلاتوكسين B1 و قدرت كمياتها فضلاً عن تحليل الرطوبة و الملوحة و الحموضة.
Eighty randomly sampled shanklish products were collected from different areas in Syria with average weight of 400 g for each sample during the year of 2003 to 2004. The samples were tested for total microflora (Fungi, yeasts and bacteria) and diagnosed for aflatoxigenic fungi which produce Aflatoxin B1and analyzed to determine moisture, salt content and acidity.

The objectives of this research were to study the effect of moisture content
and temperature of corn stored in where-houses and out-doors for production
and determination of Aflatoxin B1 in Syria.
200 tons of corn crops was used for our experiment
, and was divided 100
tons each for storage out-doors and in-doors respectively according to General
Company of Feed Stuff in Syria. Samples had been taken for 12 months by
using stratified random sampling method.
The research aims to Study the fatty acids composition of each of (Rapeseed-
Borage-Soya bean) Oil Syrian Gas Chromatography-invasive manner, and compare the
results with global studies of the same studied oils, and shed light on both the Syrian
o
ils(Rapeseed- Borage) to be used as substitutes or mixtures of health benefit or as a drug.
the study showed that the importance of the oil lies in the amount of the percentages of
unsaturated fatty acids UFA and Polyunsaturated fatty acids PUFA and Monounsaturated
fatty acids MUFA, with the highest values in the UFA installation Syrian oils to Rapeseed
oil < Borage oil < Soya bean oil, search results compared Rapeseed oil and improved
processor and the highest percentage of genetically MUFA also showed the back of Syrian
oil Borage percentage of MUFA less, but The best percentage of PUFA clear appeared in
the oil Borage.
This study, which is the first one in our country is concerned with isolation
and distribution of predatory fungi in Damascus district. The study was carried
out within three years. Six species of fungi from (١٠٢) isolates near four
different tree
s had been identified. Arthrobotrys oligospora is the most
widespread, Verticillium sp. is the less spread one. Two species of Dactylella and
Dactylaria were poor distributed.
This research highlight the business activities and the role of small and mediumsized
enterprises SME's in the national economy, and expectancy role of this sector is
increasing economic activity, securing jobs and increasing gross domestic product
GDP in
general.
It also focuses on the most important characteristics and features of the sector of
SME's in Syria. In addition to review of the main weaknesses facing the national economy
in general and this sector, in particular, which contributed to the derivation of many
suggestions contribute to the advancement and development of business environment and
SME's and to the promotion and support its role in national economy.

The investigation was carried out during 2011-2012 at the laboratories of Plant
Protection Dep., Faculty of Agriculture, and Chemistry Dep., Damascus
University. The fatty acid composition in the seed and flower of Chinaberry
(Melia azedaracht L.)
was studied by Gas Chromatography. Results showed
that four fatty acids with different rate in seed and flowers of Chinaberry. The
ratio of unsaturated fatty acid was highly in dry and fresh seed oil and reached
88.66% and 85.43%, respectively. Where the percentage of linoleic acid was
higher than oleic acid. The percentage of saturated fatty acids was highly in oil
flowers (39.97%), where the ratio of stearic acid was the highest followed by
palmitic acid. Tthe efficacy of oil extract of dry, fresh seed and flowers
Chinaberry for suppressing the growth of the fungi, Penicillium digitatum and
Botrytis cinerea on artificial media in comparison with standard fungicides,
benomyl and procymidone under laboratory condition was also evaluated.
