The current research was carried out between May and June to study the effect of adding different concentrations of fennel (Foeniculum vulgare), 0.5, 1.0 and 1.5% on the physiochemical and quality characteristics of the sponge cake stored for (0, 5, 10 and 15) days. The results of the chemical composition of the flour used in the sponge cake mix showed that the percentages of protein and fat were 10.3 and 0.8% respectively, while the ash and carbohydrate levels were 0.65 and 76.75% respectively, the moisture percentage was 11.5%. The results of the sensory evaluation showed that the cake treated with 1% of fennel powder had good colour, texture and appearance in comparison with the other treatments, while the cake treated with 1.5% of fennel showed better flavour among other treatments. The results of the physical tests showed an increase in the weight and size of the sponge cake with the increase of fennel powder, while the specific size decreased compared to the standard sponge cake. The values of peroxide and the acidity of the sponge cake stored at room temperature for 15 days were decreased with the increase of the percentage of fennel powder in comparison with the standard sponge cake. The addition of fennel to cake mix effected positively on the final product.

Research summary
تتناول هذه الدراسة تأثير إضافة تراكيز مختلفة من مسحوق الحبة الحلوة (Foeniculum vulgare) على الصفات الفيزيوكيميائية والنوعية للكيك الإسفنجي المخزن لفترات زمنية مختلفة. تم اختبار تأثير إضافة 0.5%، 1.0%، و1.5% من مسحوق الحبة الحلوة على الكيك الإسفنجي المخزن لمدة 0، 5، 10، و15 يوماً. أظهرت النتائج أن الكيك المضاف له 1% من مسحوق الحبة الحلوة كان الأفضل من حيث اللون والقوام والمظهر، بينما كان الكيك المضاف له 1.5% من مسحوق الحبة الحلوة الأفضل من حيث النكهة. كما أظهرت الفحوصات الفيزيائية زيادة في وزن وحجم الكيك بزيادة نسبة مسحوق الحبة الحلوة، بينما انخفض الحجم النوعي. بالإضافة إلى ذلك، انخفضت قيم رقم البيروكسيد ورقم الحموضة للكيك المخزن لمدة 15 يوماً مع زيادة نسبة مسحوق الحبة الحلوة، مما يشير إلى تأثير إيجابي لمسحوق الحبة الحلوة في إطالة مدة حفظ الكيك.
Critical review
دراسة نقدية: تعتبر هذه الدراسة ذات أهمية كبيرة في مجال تحسين جودة المنتجات المخبوزة وزيادة مدة صلاحيتها باستخدام مكونات طبيعية مثل مسحوق الحبة الحلوة. ومع ذلك، هناك بعض النقاط التي يمكن تحسينها. أولاً، كان من الممكن توسيع نطاق الدراسة لتشمل أنواع أخرى من الكيك أو المنتجات المخبوزة لمعرفة ما إذا كانت النتائج متشابهة. ثانياً، لم يتم التطرق بشكل كافٍ إلى الآثار الصحية المحتملة لإضافة مسحوق الحبة الحلوة على المستهلكين، وهو جانب مهم يجب مراعاته. أخيراً، كان من الممكن استخدام تقنيات تحليلية أكثر تقدماً للحصول على نتائج أكثر دقة وشمولية.

The research was conducted at the poultry farm in Kharabo, Faculty of Agriculture, Damascus University. 1080 chicks of Lohman hybrid, one day old, distributed randomly and equally into six different groups, G1….G6 (180 chicks/ group) with three re plicates in each group (60 chicks per replicate). Chicks in all groups were fattened for 42 days on Diets composed of vegetarian feeding stuffs, based on corn, soya bean meal and different additives. Chicks of G1 were fed on the main diet without adding iron or copper. The chicks in G2 and G3 were fed on the main diet mixed with 80 and 160 ppm of iron respectively. The vhicks of G4 were also fed on the main diet mixed with 8 ppm of copper. The Chicks of G5 and G6 were fed on the main diet mixed with iron and copper (80 and 8 ppm) and (160 and 8 ppm), respectively. Results demonstrated that adding iron and/or copper to the broiler diet was safe for chickens up to 42 days of age and did not affect significantly on carcass parameters. Supplementation of broiler diet with 8 ppm of copper was not associated with accumulation of copper in the tissues of liver, leg bone, breast, and thigh. Adding 80-160 ppm of iron to the broiler diets was not associated with high level of accumulation of iron in the tissues of breast and thigh but with high concentrations (p < 0.05) in the tissues of liver and leg bone.
The study was taken place at the experimental station (kharabo), Faculty of Agriculture, Damascus University, 1464 - one day old chicks of the hybrid Lohmann were used to determine the effect of adding different levels of methionine without or wit h lysine on some of carcass traits. Chicks were divided randomly and equally into 8 groups (183 each) at the first day with 3 replicates for every group (61 each).
The trial was carried out during the season 2014, on grapevines of Al-Baladi. Al Baladi, 20 years old, grafted onto rootstock, and trained in the trellis way, to study the influence of different levels of 4 times/season soil applied seaweed extract , on some qualitative and quantitative characteristics of Al-Baladi grapes.
This research is done in an experiment by plaster in the circumstances of Homs. The aim of this paper to study the effect of adding four different levels of phosphogypsum as much as (0.00, 6.72, 13.44, 20.16)ton / hectare (three replicates for eac h treatment) on bulk density and structure stability for clay soil has taken from (Kattina). The results showed improvement in the stability of the structure of soil specially (0.25-1)mm, increasing in aggregation degree , increasing of the rate of total porosity ,air filled porosity in comparison to the control at the two levels(13.44, 20.16)ton/hectare and also by increasing the added level . Whereas the dispersion ratio , and Bulk density were decreased when increasing the level of phosphogypsum at the same two levels. The main achieved results in this study showed , a significant increase in aggregation degree in the soil when increasing the ratio of the added phosphogypsum at the levels( 6.72, 13.44, 20.16) in comparasion with control . In other way the dispersion ratio was decreased and had negative relationship when increasing the level of the added phosphogypsum in comparasion with control .
This current study was carried out on B41 grape rootstock micropropagated in vitro at the General Commission for Scientific Agricultural Research (GCSAR), Syria to study the effect of different concentrations of sodium chloride on the multiplicati on and rooting stages. The results showed that the highest average of survival plants (98%), the number of new buds (8.43) and plant length (8.58 cm) were obtained in the control treatment after 4 weeks from multiplication stage. The treatment with 50 mM of sodium chloride led to reduce the multiplication rates with significant differences, while the lowest plant multiplication had occurred with 100 mM of sodium chloride and no survival plants were remained by the treatment with 150 mM of sodium chloride during multiplication stage. The highest rooting rates (% 85.30), the number of roots (4.67) and root length (6.28 cm) were also obtained in the control treatment after 4 weeks from rooting stage. The treatment with 50 mM of sodium chloride led to reduce the rooting process with significant differences. The lowest rooting results were observed with 100 mM of sodium chloride and no rooting rate was observed when plants were treated with 150 mM of sodium chloride.
