Leuconostoc bacteria was isolated from local pickled cabbage (Brassica oleracea capitata) and identified as Leuconostoc mesenteroides by morphology,biochemical and physiological. The local isolated L. mesenteroides bacteria under the optimal conditions of dextran production showed that, the highly production of dextran was 7.7g achieved by using a modified natural media comprised of 100ml whey, 10g refined sugar, 0.5g heated yeast extract, 0.01g CaCl2, 0.001g MgSO4, 0.001g MnCl2 and 0.001g NaCl at pH 6 and 25̊C for 24 hr of fermentation and by using 1ᵡ106 cell/ml as initial inoculums volume. Some applications in food technology (Ice cream, Loaf, Ketchup and Beef preservation) have been performed with processed dextran. The results showed examined product as related to color, solubility and viscosity for both ice cream and ketchup in addition to softness, puffiness in loaf core and show high efficiency as cryoprotective agent in beef preservation at -18°C with out being freezed.

This study investigates the potential of biogas recovery from used engine oil (UEO) by co-digestion with animals’ manure, including cow dung (CD), poultry manure (PM), and cattle manure (CM). The experimental work was carried out in anaerobic biodigesters at mesophilic conditions (37°C). Two groups of biodigesters were prepared. Each group consisted of 4 digesters. UEO was the main component in the first group of biodigesters with and without inoculum, whereby a mix of UEO and petroleum refinery oily sludge (ROS) was the component in the second group of biodigesters. The results revealed that for UEO-based biodigesters, maximum biogas production was 0.98, 1.23, 1.93, and 0 ml/g VS from UEO±CD, UEO±CM, UEO±PM, and U
... Show MoreGas and downhole water sink-assisted gravity drainage (GDWS-AGD) is a new process of enhanced oil recovery (EOR) in oil reservoirs underlain by large bottom aquifers. The process is capital intensive as it requires the construction of dual-completed wells for oil production and water drainage and additional multiple vertical gas-injection wells. The costs could be substantially reduced by eliminating the gas-injection wells and using triple-completed multi-functional wells. These wells are dubbed triple-completion-GDWS-AGD (TC-GDWS-AGD). In this work, we design and optimize the TC-GDWS-AGD oil recovery process in a fictitious oil reservoir (Punq-S3) that emulates a real North Sea oil field. The design aims at maximum oil recovery us

... Show MoreRabi’a played an important part in the conquer of the east. This tribe had
asked to conquer the fareway provinces, in spite of these difficulties, Rabi’a
did that and settled in.
This tribe was among the opposition of the Umayyad caliphate in the east,
because this tribe thinks that the caliphate was with the Mudhariyat and
Qaisiat tribes who were their enemies.
In spite of that, they were very limited cases in which Rabi’a was the
adherence of the caliphate against her enemies like Al-Harith b. Surieg , and
were against Qutaiba b. Muslim al- Bahily.
Rabi’a assisted Amr b. Muslim movement against the Umayyad governor
Qutaibe, because the later wanted to sent her faraway from Mawara al- Nahar.

الأطفال هم قادة المستقبل، بل هم المستقبل ذاته، وهم الأمل المنتظر لبناء وطن كريم. لذلك، من الضروري أن ينشأ الطفل في بيئة آمنة تتيح له اللعب والنمو والتعلم، إلى جانب حصوله على نصيب وافٍ من الاهتمام والرعاية. ومع ذلك، فإن ما لا يقل عن ربع أطفال العالم لا يتمتعون بالعديد من الحقوق الأساسية. وبالنسبة لأطفال العراق، الذين أنهكتهم الحروب والأزمات، فإن معاناتهم تبدو أكثر قسوة وفقًا للعديد من الدراسات والتقارير. شهد ا
