Some Factors determining the virulence of Escherichia coli ( E. coli ) isolates were studied ,of 25 isolates , 17(group A) uropathogenic E. coli ,6 (group B) infected gastrointestinal tract , 2 (group C) infected wound , beside these group we use the standard strain E. coli HB101 as control group. The twenty five isolates were tested for adherence capability to human buccal cavity epithelial cells by in vitro experiment . The results showed that all isolates have different adhesion capability with mean ranging from (14.35±11.39) to (33.80 ± 22.68) bacteria / epithelial cell It was noticed that isolates EU9, ES6, EW17 displayed high adhesive capability with mean value (33.80 ± 22.68), (32.60 ± 21.19), (29.90±22.50) bacteria /epithelial cell respectively, while the isolates EU4 displayed a lowest adhesive capability with mean value of (14.35±11.39) bacteria / epithelial cell. It was also found that there was no significant difference ( P ≥ 0.001) for adhesive capability among EU9, ES6, EW17, but the adhesive capability for these isolates was significantly higher (P ≤ 0.001) compared to standard strain which showed adhesive capability with mean value (0.55± 0.88),thus these isolates were selected for further experiments to study others virulence factors such as ability to agglutination human , rabbit , sheep erythrocytes in mannose – sensitive manner and production of haemolysin , biofilm. The results revealed that all isolates had nearly the same hemagluttination pattern in the absence of D-mannose while the pattern is different in the presence of D- mannose, where the isolates EU9, ES6 show ability to agglutinate human and sheep erythrocytes and so considered as Mannose Resistant Hemagluttination (MRHA) while the isolate EW17 did not show this ability and considered as Mannose Sensitive Hemagluttination ( MSHA). It was also found that all isolates have ability to produce haemolysin and biofilm formation but in different pattern.
This tagged research deals with the manifestations of femininity in Mahmoud Fahmy's drawings by studying and monitoring the presence and how women were represented in the drawings of the artist Mahmoud Fahmy. Through the drawings of the expatriate Iraqi artist, Mahmoud Fahmy, in highlighting the manifestations of beauty for women, which constitute a formal characteristic that appears through the body, and Fahmy depicts it in an atmosphere of realism at times and magical realism at other times, as the research consists of four chapters. Through the following question: Did femininity appear in the drawings of the artist Mahmoud Fahmy? The importance of the research is that it sheds light on the manifestations of femininity in the drawings
... Show MoreThe aim of this paper is to translate the basic properties of the classical complete normed algebra to the complete fuzzy normed algebra at this end a proof of multiplication fuzzy continuous is given. Also a proof of every fuzzy normed algebra without identity can be embedded into fuzzy normed algebra with identity and is an ideal in is given. Moreover the proof of the resolvent set of a non zero element in complete fuzzy normed space is equal to the set of complex numbers is given. Finally basic properties of the resolvent space of a complete fuzzy normed algebra is given.
In this study the adsorption of cefixime on to selected Iraqi clay bentonite. The aim of this study is to search for selective active surface in adsorption of the drug and to act as physical antidotes in treatment of poisoning if the drug is taken in quantities higher than the recommended dosages. Quantitative estimation of the drug adsorption has been done by utilizing the technique of UV spectrophotometry in λmax (273) nm at different conditions of temperature (25, 37, 45) ˚C found the adsorption decrease with increase the temperature. Study of clay weight of bentonite (0.1-1.5) gm found the adsorption increase with increase of clay weight, study effect of pH (1.2, 3, 5, 7) on adsorption of bentonite found the optimum adsorption

The traditional technique of generating MPSK signals is basically to use IQ modulator that involves analog processing like multiplication and addition where inaccuracies may exist and would lead to imbalance problems that affects the output modulated signal and hence the overall performance of the system. In this paper, a simple method is presented for generating the MPSK using logic circuits that basically generated M-carrier signals each carrier of different equally spaced phase shift. Then these carriers are time multiplexed, according to the data symbols, into the output modulated signal.
