What distinguishes secondary students is that they are in adolescence and this age group is known for its tendency for non-compliance and out of the ordinary. Thus, they are more prone to foodborne diseases. This study aimed to assess food safety knowledge and practices among secondary students at twelve public secondary schools in all six municipalities in Tripoli city, Libya. A cross-sectional survey was carried out among 1874 students in which 55.2% of the respondents were females and 44.8% were males. The majority of the respondents (71.5%) were between the age of 16 and 17 years. Data were analyzed by the SPSS. The findings revealed that 83.4% and 87.5% of students have good knowledge and a moderate level of practices of food safety, respectively. The findings also revealed that only 7.8 % of students reported that they "always" wash their hands before eating breakfast in school. It was observed that there was a significant association between food safety knowledge scores and students' municipality and a significant association between food safety practices scores and students' municipality, and mothers' education level of secondary school students (P <0.05). In conclusion, there was a weakness of some important knowledge points and practices of food safety. Therefore, an effective and continuous education program for these teenagers is necessary. Also, the authorities should provide appropriate facilities at schools that enable students to wash their hands.

Tannins from the root bark of Quercus aegilops L. were extracted in two successive seasons and their astringency score and antioxidant potential were evaluated using bovine serum albumin (BSA) radial diffusion and 2,2- Diphenyl – 1-Picrylhydrazyl (DPPH) assay methods respectively. The results revealed that the root bark of this oak species contained on average 11.39 %( w/w) tannins as gallic acid, of which about 79% are hydrolyzable ( HT) and 21% condensed (CT) tannins with the former composed mainly of ellagitannins and much fewer gallotannins and free gallic acid. The results also revealed that the crude root bark powder and its purified tannins have astringency scores of 15.8 and 138.98 mg BSA/g respectively. The antioxidant potential was evaluated by DPPH assay and expressed as inhibition capacity (IC50) was 149.7 ppm and 19.24 ppm for the crude bark powder and its purified tannins respectively indicating the superior antioxidant potential of these tannins to that of ascorbic acid. The highly-antioxidant functional tea prepared from these tannins was clear and acceptable to tasters.

Paronychia argentea is a wild medicinal herbaceous herb that contains many secondary metabolites. It grows wild in Jordan under harsh high salinity soil conditions. This study was conducted to investigate the effect of salinity stress on growth, biochemical responses, and ion uptake of in vitro Paronychia argentea micro plants. Our results revealed a clear reduction in all growth parameters in response to an increase in salinity level used (0, 25, 50, 100, 200 mM). When the growth medium was supplemented with 200 mM NaCl; the fresh and dry weights were reduced by 40% compared with the control treatment. Moreover, micro plant uptake of phosphorus calcium and potassium ions decreased with increasing salinity levels. The Mg++ content was increased by 10% at the 25 mM level of NaCl compared with control, while it declined by 20% at 200 mM of NaCl. On the other hand, Na+ uptake increased with increasing salinity levels and reached a maximum value of (18328 ppm/D. W) at 200 mM NaCl. Moreover, proline content increased in response to salinity level to record maximum value (80.8 µmole/g) at 200 mM NaCl compared to (30.4 µmol/g) obtained in the control. Quercetins content in P. argentea micro plants was increased by 1.7-fold in concentration in response to salinity at 50 mM of NaCl, while an about 7-fold increase in the concentration of isorhamnetin content was obtained due to salinity at 100 mM.

Nutritional, rheological, and sensory evaluation for Tere (Rokak) bread supplemented with 0, 2.5, 5, 7.5, and 10% of inulin or wheat bran were studied. The chemical composition of bread was slightly affected by these treatments, while energy values were reduced from 354.24 to 315.76 calories/100g. The results showed that Farinograph water absorption decreased from 70.2 to 50.3% and Mixing Tolerance Index from 34 to 0.00 BU with an increase in development time from 9.3 to 20 min, stability time from11-14.9 min, and quality number from 138-200 by increasing of inulin addition. The most pronounced effect of bran addition was on Farinograph stability and quality number which decreased from 9.3min and138 to 6.9min and 117 respectively. On the other hand, inulin decreased the Amylograph viscosity peak at heating from 840 t0 610 BU and the final viscosity at cooling from 1250 to 990 BU. Inulin addition significantly reduced the amount of required water to make Tere bread from 66% to 54% compared to control and bran. Inulin reduced about 3cm of bread diameter, while 7.5% of bran addition increased 3cm of Tere diameter. Also, the sensory evaluation showed that inulin and bran addition up to 10% had a slight effect on Tere bread compared to control , and their total acceptability was 70%-80%. No mold growth was observed on stored bread for three months which emphasized their resistance to any visible growth.

In Jordan, crossing local sheep with the exotic breed has an acceptable sound by farmers but needs scientific proof for planned-ahead crossing and introgression. This work aimed to find the best mating strategy on economic carcass and non-carcass traits of produced lambs under an intensive production system in Jordan. The mating strategy among Awassi and Chios for two years was designed to obtain different pure- and cross-bred lambs. They were pure Awassi, pure Chios, and reciprocal crosses of Awassi-Chios and Chios-Awassi lambs for two years. The studied factors included sex of lamb, breed, lamb birth type, age at slaughtering, and their two-way interactions. The lamb sex significantly affected (P < 0.001) most carcass and non-carcass traits of economic importance. Similarly, the effect of age was notable (P < 0.05) on all carcass and non-carcass traits. The breeds were significantly different (P < 0.05) for the hot carcass, tail, and internal organs weights. Therefore, the use of Awassi sire as a paternal contributor for producing meat over one year in crossbreeding can be implemented for increasing carcass weights. The heterosis effect had only significant for tail weight. Significant differences for the liver with and without a trachea, kidney with and without fat, heart with and without fat, and lung between reciprocal crosses for heterosis percentages always favored the reciprocal cross of Awassi female parent. Interaction effects of age with sex were detected on body weight, carcass length, and kidney, while interaction effect of birth type with sex was significant for body weight and some internal organs. finally, significant interaction effects of the breed with both sex and birth type were significant for the cold carcass, tail, and some organs weights. In the present study, sheep producers might be benefited better if Awassi sire is used as a paternal contributor for producing meat over one year in crossbreeding strategy with Chios for increasing carcass weights.

مع التغيرات المتلاحقة في النمو السكاني وازدياد الطلب على الغذاء في الدول النامية، أصبحت إدارة الموارد الطبيعة والمحدودة، بطريقة منهجية وعلمية ومستدامة أمراً ضرورياً. ويهدف هذا البحث إلى تقديم نهج متكامل لعملية تحليل ملاءمة الأراضي الزراعية لنمو محصول القمح في منطقة جورين من سهل الغاب في سوريا باستخدام نموذج التسلسل الهرمي التحليلي (AHP) ضمن بيئة نظم المعلومات الجغرافية (GIS). و لتقييم درجة الملاءمة، تم تحديد ثمانية معايير وهي: نسيج التربة، الميل، عمق التربة، محتوى المادة العضوية، محتوى كربونات الكالسيوم (CaCO3)، سعة التبادل الكاتيوني (CEC)، درجة الحموضةPH) )، والتوصيل الكهربائي (EC)، ثم تم إعداد الخرائط اللازمة وفي مرحلة لاحقة تم إجراء المقارنات الثنائية بين المعايير المدروسة. وأظهرت النتائج أن 25.6٪ من المساحة المدروسة مناسبة جداً وذات ملاءمة عاليةS1، بينما شكلت نسبة المناطق المتوسطة الملاءمة S2 56.33٪، وتوزعت 16.45٪ من أراضي منطقة الدراسة بملاءمة هامشيةS3، وكانت 1.61٪ هي أراضي غير صالحة لزراعة القمح N1.

Agriculture played and continues to play an important role in the Syrian economy, both in terms of the gross domestic product and employment. The consequences of the seventh-year crisis continue to affect the agricultural sector. The lack of inputs and high prices, coupled with the difficulty of harvesting and marketing crops, are among the most important agricultural issues that resulted from the crisis. Before the crisis, the agricultural sector suffered from many problems resulting from the government's neglect of it, represented by the weakness of governmental investments in agriculture, in addition, the complex administrative problems of management and organization, which led to a decline in productivity and efficiency. After the outbreak of the crisis, a large number of people were forced to leave the rural areas, which led to a very significant deterioration in agriculture and production. Syria has imported most types of important crops, such as wheat, from abroad to cover the needs of the local market, and this will be discussed in detail in this article. Therefore, this article shows the need for serious efforts to restore the agricultural sector which is the most important element in the Syrian economy and sustainable food and nutrition security for the urban and rural areas. Even though the crisis is not over, the conditions for investing in the recovery of the sector are present in many areas of the country. Such investment will not only reduce the need for humanitarian assistance but will also reduce migration and encourage the return of migrants.
