Syria consumes as many as ١٢٨ thousand tons of detergents yearly. The powder detergent with added enzyme represents is about ٣٥ % of the total production .The enzyme content in the detergent is ٠,٥-١,٠ %. Amylases, Lipases, Proteases, and cellulases are the main enzymes used in detergents. Enzymes are known to have protein structure and play role in biocatalysts during the cleaning process. Enzyme activity is affected by heat and the detergent s components such as oxidants, bleachers, and brighters. This research was focused on using Volgemyta method, which traditionally used for saliva and blood analyses to determent the Amylase activity in detergents produced in Syria. The result in dicate that this setteed may be used to determent the commercial Amylase activity in water, and in ٠,١ % Sodium chloride water solution, and finally in physiological solutions . The effect of the different detergents on the Amylase activity has been studied as well. As a result, the addition of any extra amount of Amylase makes no increase or improvement in the cleaning performance of the detergent.

Research summary
تتناول هذه الدراسة فعالية إنزيم الأميلاز في المنظفات السورية. يتم استخدام الأميلاز، إلى جانب إنزيمات أخرى مثل الليباز والبروتيآز والسلولاز، في مساحيق الغسيل لتحسين أداء التنظيف. تم استخدام طريقة فولجموت، التي تُستخدم عادةً لتحليل اللعاب والدم، لتحديد فعالية الأميلاز في المنظفات. أظهرت النتائج أن إضافة كميات إضافية من الأميلاز لا تحسن من أداء التنظيف. كما تم دراسة تأثير مكونات المنظفات المختلفة على فعالية الأميلاز، ووجد أن فعالية الأميلاز تتأثر بالحرارة والمكونات الأخرى مثل المؤكسدات والمبيضات. تم تعديل شروط وحدة فعالية الأميلاز لتتناسب مع ظروف الغسالة الآلية، وتم اختبار فعالية الأميلاز في الماء ومحلول كلور الصوديوم والمحلول الفيزيولوجي. أظهرت النتائج تباينًا كبيرًا في فعالية الأميلاز بين المنظفات المختلفة، مما يشير إلى ضرورة تحليل الإنزيمات المستوردة وتحديد مدى الاستفادة منها.
Critical review
تعتبر هذه الدراسة خطوة مهمة نحو فهم فعالية إنزيم الأميلاز في المنظفات السورية، ولكن هناك بعض النقاط التي يمكن تحسينها. أولاً، الدراسة تركز بشكل كبير على الأميلاز دون النظر بشكل كافٍ إلى تأثير الإنزيمات الأخرى المستخدمة في المنظفات. ثانيًا، كان من الأفضل تضمين تحليل اقتصادي لتحديد ما إذا كانت إضافة الأميلاز فعالة من حيث التكلفة. ثالثًا، الدراسة تعتمد بشكل كبير على طريقة فولجموت، وكان من الممكن استخدام طرق تحليلية أخرى للتحقق من النتائج. أخيرًا، لم يتم التطرق إلى تأثير الأميلاز على البيئة، وهو جانب مهم يجب مراعاته عند تقييم فعالية المنظفات.
Questions related to the research
  1. ما هي الإنزيمات الرئيسية المستخدمة في المنظفات السورية؟

    الإنزيمات الرئيسية المستخدمة في المنظفات السورية هي الأميلاز، الليباز، البروتيآز، والسلولاز.

  2. ما هي طريقة فولجموت المستخدمة في الدراسة؟

    طريقة فولجموت هي طريقة تحليلية تُستخدم عادةً لتحليل اللعاب والدم، وتم استخدامها في هذه الدراسة لتحديد فعالية الأميلاز في المنظفات.

  3. ما هي العوامل التي تؤثر على فعالية الأميلاز في المنظفات؟

    تتأثر فعالية الأميلاز بالحرارة ومكونات المنظفات مثل المؤكسدات والمبيضات والقلويات.

  4. هل إضافة كميات إضافية من الأميلاز تحسن من أداء التنظيف؟

    لا، أظهرت الدراسة أن إضافة كميات إضافية من الأميلاز لا تحسن من أداء التنظيف.

Ten isolates of fungi-producing amylase were isolated from six different sources (different kinds of soils - air-spoilage bread) on malt extract agar (MEA) and potato dextrose agar (PDA). Four isolates were identified in Museum of Natural History Paris- France and six isolates were identified in the College of Agriculture, Damascus University. The ability of fungal isolates for secretion aflatoxins B1, B2 and G1 was detected by thin layer chromatography technique and the quantity of toxins was determined by using electronic scanner in Syrian Atomic Agency by comparison with similar standard toxins.
The Syrian detergent companies used to add high percentage of perborate salt in laundry detergents formulation to achieve best bleaching and cleaning results. And usually the bleach activator which transforms the peroxides into more effective mate rials, was added to the formulation in non specified doses. The studies have been made of the effect of the bleach activator -TAED on the perborates salt show the possibility to reduce the amount of the used perborates by controlling the - Perborates / TAED percentage in the detergent formulation . The released active oxygen depends on the ambiant temperature where weak activity where detected when temperature exceeds ٦٠ celsius. This study shows the role of the detergent formulation on the bleach activator where it releases the active oxygen in a higher percentage when monohydrate sodium perborate is used, and no effects were detected on the tensile strength of the used fabric.
The purpose of this study is to Measure privet insurance companies in Syria degree of commitment to marketing effectiveness dimensions recording to Kotler’s model which involve Customer Philosophy, operational efficiency, strategic orientation, ad equate marketing information and integrated marketing organization, and that is according to the opinions of marketers and employees in these companies through preparing a questionnaire which had been refined and verified of its credibility. The study concluded a main result, which is that Syrian privet insurance companies adopted marketing effectiveness when they market there services , Finally the study came up with a number of Recommendations, that can lead to improve the reality of marketing practices in the private insurance companies in Syria.
This research aims to introduce the species of insurance located in the Syrian market, and compare them in terms of return and risk resulting from each of them, in addition to trying to develop a model to measure the size of the development of the insurance sector in the Syrian market, using multivariate equations. Where the study showed that there is a difference between the types of insurance in terms of the size of the return and risk resulting from it has been shown that most types of insurance have an average profit, excluding motor insurance Complementary and mandatory, in addition to the most common types of insurance profitability is pension insurance, where profit per pound per 0.9991 followed by insurance against theft and transport insurance. Conversely study showed that the average profit of the fire is 0.6252 per SP one, but the risk in this type of insurance is very high risk where the standard deviation of about 2.06264, and followed in terms of high-risk insurance hulls of ships where the standard deviation for securing ships .81732. With regard to the following types: life insurance and pension insurance and engineering insurance of civil liability and personal insurance are all enjoying a good profit and the average rate risk is acceptable. The study recommended that insurance firms should carry out a study and the reality of insurance in the Syrian market in terms of the size of the risks and value of insurance premiums, especially life insurance types where there are no actuarial studies specialist, in addition to giving fire insurance and compulsory motor vehicle further study and development of many of the controls of would reduce the size of the dangers that it contains two types of insurance.
In this study it has been determined the total phenols percentage of three Syrian honey types. Then the relation has been studied between phenols level in these three types of Syrian honey and its effect on the Escherichia coli which causes many t ypes of intestinal and uric infections and causes many diseases as bleeding.
