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.

We have investigated in this research, the contents of the electronic cigarette (Viber) and the emergence of the phenomenon of electronic smoking (vibing) were discussed, although the topic of smoking is one of the oldest topics on which many articles and research have been conducted, electronic smoking has not been studied according to statistical scientific research, we tried in this research to identify the concept of electronic smoking to sample the studied data and to deal with it in a scientific way. This research included conducting a statistical analysis using the factor analysis of a sample taken randomly from some colleges in Bab Al-medium in Baghdad with a size of (70) views where  (КМО) and a (bartlett) tests

The Effect of Combination Ovariectomy and D-galactose Administration on Alzheimer's Animal Model
...Show More Authors

Background and purpose: Animal model helps researchers to evaluate new treatment plan for human and understand pathological mechanism involved in a development of disease. The use of rats as an animal model for Alzheimer's research has become a favorite among researchers. Rats are capable in mimicking Alzheimer disease due to their intelligence and quick adaptation to nature. At present there are several methods that can be used to induce Alzheimer's animals, but each method has advantages and disadvantages. We need to learn other methods that can provide many advantages and few disadvantages. The Amyloid-beta 42 (Aβ-42) and Reactive Oxygen Species (ROS) are thought to play an important role in the pathology of Alzheimer’s disease. Th

The Effect of the Solution Heat Treatment on the Mechanical Properties of Aluminum-Copper Alloy (2024-T3) Using Rolling Process
...Show More Authors

The effect of solution heat treatment on the mechanical properties of Aluminum-Copper alloy. (2024-T3) by the rolling process is investigated. The solution heat treatment was implemented by heating the sheets to 480 C° and quenching them by water; then forming by rolling for many passes. And then natural aging is done for one month. Mechanical properties (tensile strength and hardness) are evaluated and the results are compared with the metal without treatment during the rolling process. ANSYS analysis is used to show the stresses distribution in the sheet during the rolling process.  It has been seen that good mechanical properties are evident in the alloy without heat treatment due to the strain hardening and also the mechanical
