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.
The last ten years observed a shift enormous scientific in the method and way that it deals professional with the cost accounting and reflected the result those shift enormous scientific of increase the competitive environmental that accompanied the emergence of a modern manufacturing environmental on surface the long roductive life and emergence advanced information technology that give a central focus of his important on client with growing global markets growth on a large scale.
The research aim to define the concept of cost awareness, the concept and methods of strategic cost management and the role of cost awareness for managers of industrial units in strategic of cost managem

under different values of pressure of oxygen gas. The structure of
multi-walled carbon nanotubes powders has been characterized by
low-angle X-ray diffraction .The morphology of carbon nanotube
powder was examined by transmission electron microscope. The
capacitance-voltage and current- voltage (dark and illumination
current) characterization were measured under different values of
pressure (10-3, 10-4, 10-5) mbar of oxygen gas
The multi-focus image fusion method can fuse more than one focused image to generate a single image with more accurate description. The purpose of image fusion is to generate one image by combining information from many source images of the same scene. In this paper, a multi-focus image fusion method is proposed with a hybrid pixel level obtained in the spatial and transform domains. The proposed method is implemented on multi-focus source images in YCbCr color space. As the first step two-level stationary wavelet transform was applied on the Y channel of two source images. The fused Y channel is implemented by using many fusion rule techniques. The Cb and Cr channels of the source images are fused using principal component analysis (PCA).
... Show MoreTerrorist crime is considered a serious act that outweighs all other crimes in terms of impact and result, because it has a wide range on societies, and it also contains a great thing of danger represented in its purpose, and here describing terrorism as a crime is a description that does not give the full right to this behavior or that it It abbreviates it and does not show its actual reality, given that terrorism contains several different crimes and the roles of its contributors, and these roles are necessary to reach the result or the end. In which each episode is complementary to the other, it is not a single act, but rather several joint and complex actions that in turn all lead to the result, and the agreement in the terrorist pro
... Show MoreThe study of the validity and probability of failure in solids and structures is highly considered as one of the most incredibly-highlighted study fields in many science and engineering applications, the design analysts must therefore seek to investigate the points where the failing strains may be occurred, the probabilities of which these strains can cause the existing cracks to propagate through the fractured medium considered, and thereafter the solutions by which the analysts can adopt the approachable techniques to reduce/arrest these propagating cracks.In the present study a theoretical investigation upon simply-supported thin plates having surface cracks within their structure is to be accomplished, and the applied impact load to the
