This study aimed to study the inhibition activity of purified bacteriocin produced from the local isolation Lactococcuslactis ssp. lactis against pathogenic bacteria species isolated from clinical samples in some hospitals Baghdad city. Screening of L. lactis ssp. Lactis and isolated from the intestines fish and raw milk was performed in well diffusion method. The results showed that L. lactis ssp. lactis (Lc4) was the most efficient isolate in producing the bacteriocin as well observed inhibitory activity the increased that companied with the concentration, the concentration of the twice filtrate was better in obtaining higher inhibition diameters compared to the one-fold concentration. The concentrated bacteriocin was purified using the gel filtration column and Sephacryl S-200. The results showed the high inhibitory activity of the purified bacteriocin after the purification against the positive and negative bacteria of the Gram stain under study compared to the one-fold concentration and two-fold before purification , The diameters of the inhibition zones after gel-filtering of the purified bacteriocin reached S. aureus, S. epidermidis, P. aeruginosa, E. coli, E. clocae and S. marcescens (23, 25, 26, 20, 22 and 28) Mm respectively. The carbohydrate content of purified bacteriocin from L. lactis ssp. lactis (Lc4) isolate was 6.02% with a molecular weight of 6310 Dalton. The results showed that purified bacteriocin retained its inhibitory activity at pH 2-10 and showed the highest inhibition at pH 4-6 and lost at pH 12. The purified bacteriocin was characterized by thermal stability. It retained its effectiveness when exposed to 40, 60, 80, 100°C for 30, 15, 5 minutes and 120°C for 15.5 minutes and lost 50% of its effectiveness when exposed to 120°C for 30 minutes. Results The purified bacteriocin was effectively retained when treated with enzyme pepsin and trypsin of 37°C for one hour and at pH 7.
The current research aims to :
•know the level of social intelligence of the sample as a whole .
. •taraf statistically significant differences in social intelligence between disadvantaged and
non-disadvantaged peers .
To achieve these objectives, the selected sample of Talbhalmrahlh medium and specifically
students of the second grade average, were chosen randomly stratified's (360) students
included sex (male, female) and (deprived of the Father and the non-deprived) for the
academic year (2013-2014) for the province of Baghdad on both sides (Rusafa-Karkh (
As applied to them measurements of social intelligence, which is prepared by the researcher,

The current research aims to shed light on the Global Reporting Initiative (GRI), which helps to report financial and non-financial information by economic units in general and listed on the Iraq Stock Exchange in particular. The research was based on a main premise that apply the criteria of the Global Reporting Initiative (GRI) would provide useful information to users to help them make appropriate decisions. To achieve the goal of the research, the descriptive analysis method was used, and quantitative analysis was used. At the level of the descriptive analysis method, a desk survey was conducted. As for the quantitative analysis, it relied on applied data through a questionnaire form (Questioners) as a research tool, and the

The banking credit has a significant role in supporting the economic development process as it is considered a financial medium between the depositors and investors through turning the money received by the bank in from of banking deposits from a person who has a monetary surplus into another person in need of this surplus . this credit contributes also in directing the economic activities toward investing project generally and strategic investing projects in special that the country lacks which is in need of optimum exploitation to the available resources. In addition , the banking credit represents the most important source of revenues that the banks gain and contribute in increasing their profitability.
يعد موضوع الرساميل الفكرية من المواضيع الحرجة في نجاح وتميز المنظمات بالأخص اذا ما تم ربطه بإدارة خبرة الزبون، وبسبب ما تتسم به البيئة العراقية من حركية اثرت على جميع القطاعات ومنها القطاع المصرفي ،كان من المهم البحث في انواع الرساميل الفكرية وعلاقتها بإدارة خبرة الزبون خصوصا عند مدراء المصارف الأهلية، تكمن اهمية البحث في ارتباط متغيراته ببناء القدرات الاستراتيجية للمصارف لتحقيق التميز والاست

This study was aimed to extract the effective material from the dry nests of termites and detect its antibacterial activity against some pathogenic bacterial isolates and inhibit synthesis of its biofilm. Termites dry nests were collected and the effective material was extracted then the antibacterial activity was detected using the disc diffusion assay. Results were showed that the extract have antibacterial material from the Termites dry nests, this extract showed antibacterial activity against Gram positive bacteria (Staphylococcus aureus) at (21.5mm) and Gram negative bacteria ( Enterobacter sp. and Pseudomonas aeruginosa) at (26 mm and 20 mm) respectively by inhibiting their growth, as well as its effect on biofilm production o
