The study included the collection of samples of raw cow milk to isolate Leuconostoc bacteria, samples were sub cultured on De-Man Rogosa Sharpe-Vancomycin medium, the pure colonies were selected and subjected to the cultural and microscopically tests, according to that 25 cocci bacterial isolates were obtained, then isolates were subjected to biochemical tests. Result of tests showed that 12 isolates belong to the genus Leuconostoc out of 25 cocci bacterial isolates, Vitek2 system was used as a supplementary step. Results of final identification showed that 3 sub species were obtained included Leuconostoc mesenteroides ssp. cremoris 9 out of 12 isolates, while it was 2 isolates of Leuconostoc mesenteroides ssp. mesenteroides and one isolate Leuconostoc mesenteroides ssp. dextranicum. The study included the collection of 15 isolate of diarrhea causative bacteria which subjected to cultural and microscopically, biochemical tests and Vitek 2 system, about the results of identification, 9 isolates out of 15 isolates belonged to Escherichia coli,3 isolates of Shigellagroup,2 isolates of Salmonella ser. paratyphi A and one isolate of Vibrio cholerae, the selected isolates were tested to Antibiotic sensitivity test against 11 antibiotics, the results showed that all isolates were resistant to Ampicillin and sensitive to Imipeneme. Screening of L. mesenteroides ssp. cremoris isolates was done to select the more efficient isolate producing bacteriocin by using well diffusion method, the result showed that L. mesenteroides ssp. cremoris (Lc3) and L. mesenteroides ssp. cremoris (Lc4) isolates gave the highest inhibition against E. coli, Shigella group, Salmonella ser. paratyphi A and Vibrio cholerae, the diameters were 13, 12, 12 and 12 mm respectively for the L. mesenteroides ssp. cremoris (Lc3) isolate, while the L. mesenteroides ssp. cremoris (Lc4) isolate diameters were 13, 12, 12 and 11mm respectively. The synergistic effect between bacteriocin of both isolates L. mesenteroides ssp. cremoris (Lc3) and L. mesenteroides ssp. cremoris (Lc4) with antibiotics was studied against multidrug resistant diarrhea causative bacteria. Synergistic effect between bacteriocin of both isolates with antibiotics was observed. The activity of antibiotics with bacteriocin was increased, like Cefixime, Tetracycline, Trimethoprim-sulfamethoxazole, Ampicillin antibiotics against E. coli, and Cefotaxime, Ceftriaxone, Trimethoprim-sulfamethoxazole, Cefixime antibiotics against Shigella group, and Trimethoprim-sulfamethoxazole antibiotic against Salmonella ser. paratyphi A and Ampicillin, Trimethoprim-sulfamethoxazole, Cefixime antibiotics against Vibrio cholerae.
This research aims to know and the role of the marketing recovery dimensions in improving the organization's reputation through an exploratory study of private banks in the city of Baghdad. The aim of the research is to define the role of the marketing recovery through its dimensions (compensation, apology, speed of response, assistance and problem solving), in improving the organization's reputation, as the research will attempt to provide a theoretical framework for the dimensions studied through the most important of what researchers presented and then conduct the applied aspect of the research. Data were collected using a questionnaire-based survey consisting of 35 questions and distributed to 110 managers of private banks in

The purpose of this study is to investigate learners' listening comprehension problems with Englishlectures. The study was guided by research question (What are the listening comprehension problems learners have with lectures in English).Furthermore; the main significant goal were declared through conducting this study, as well as providing some procedures of distribution the questionnaire of the study.Moreover, it presents several definitions of listening. This study definitely depends on questionnaire instrument to gathering the required data. The participants of the study were 30 learners completed their secondary school and joined at the college. Based on the findings among the five factors (text, speaker, task, environment, and list

Some studies showed that writing anxiety has an impact on the acquisition of language learning. This study; however, teaches the cognitive strategies (PLAY & WRITE) as a writing strategy, so as to decrease students’ use of it when experiencing writing anxiety at the academic writing level. The sample has been (100) second-stage Department of English learners at the College of Education (Ibn –Rushd), in the University of Baghdad-Iraq. They have been randomly selected and divided into experimental and control groups; (50) students in each group.

The study aims at diagnosing the importance of environmental analysis (external, industrial and internal) in the organization's strategy for the development of public organizations. The theoretical problem derived from the existence of a knowledge gap for studies and research that dealt with the variables of the study. Three public organizations were selected as the study society (the Civil Defense Directorate, the Directorate of Nationality, Passports and Residency, the General Traffic Directorate). The sample of the study was a sample of (215) managers (managers, department managers, Analysis of the data and hypothesis testing using the appropriate statistical tools, Pearson, the simple and multiple regression coefficient to te

In this paper two ranking functions are employed to treat the fuzzy multiple objective (FMO) programming model, then using two kinds of membership function, the first one is trapezoidal fuzzy (TF) ordinary membership function, the second one is trapezoidal fuzzy weighted membership function. When the objective function is fuzzy, then should transform and shrinkage the fuzzy model to traditional model, finally solving these models to know which one is better
