Synergistic Effect of Potassium Clavulanate in Combination withCefamandol and Ceftazidime on B- Lactamase, Extracted From Resistant E.coli
...Show More Authors

The aim of this study was to evaluate in-vitro activity of Cefamandol and Ceftazidime, in combination with potassium clavulanate against 10 uropathogenic E.coli isolated from patients with chronic complicated urinary tract infections (UTIs), these isolates were identified by the Api identification systems.The antimicrobial susceptibility tests were determined by Kirby-Bauer method and the minimum inhibitory concentrations of Cefamandol and Ceftazidime, were determined, by tube method. These isolates were resistant to Ampicillin (Amp), Amoxicillin (Amo), Carbenicillin (Cb), Ticarcillin (Tic), Amoxicillin\ Potassium Clavulanate {Augmentin}, (Amo\CA), Ticarcillin\ Potassium Clavulanate {Timentin} (Tic\CA), Cefamandol (Cfm) and Ceftazidime (Cfz), also resistant to other antibiotics, such as Tetracycline, Chloramphenicol, Trimethoprim and (50% of the isolates were resistant to Nalidixic acid and Rifampicin). Transfer of plasmids  by direct conjugation experiments were performed by mating 10 strains  with recipient strain E.coliK12C  600 Rif or Nal resistant, and cell free b- lactamases were prepared and detected by macro-iodometric method. The activities of each cell free b– lactamases extract against Cfm and Cfz were determined by disks diffusion method (microbiological Masuda method) and by macro-iodometric method. The activity of b- lactamases was inhibited by the addition of Potassium Clavulanate. Conclusion:

Good effectiveness of Cfm\ CA and Cfz\ CA was obtained against resistant strains of E.coli due to complicated urinary tract infection (UTIs).

Key words: b- lactamases, Cefamandol, Ceftazidime, Timentin and  Augmentin .

Effect of Different Environmental and Nutritional Factors on Biosurfactant Production from Candida guilliermondii
...Show More Authors

Yeast strain S9, which produced a high amount of biosurfactant, was isolated from pickledolive and identified as a strain of Candida guilliermondii using VITTEK 2 compact system, this strain was selected out of 13bioemulsifier producing strains. The effects of some environmental and nutritional factors on biosurfactant production were evaluated, the maximum value of E24% was observed at pH 4 which was 70% and the optimal temperature for biosurfactant production was 30 °C, E24% was 75%. Among different edible and heavy oils, the sesame oil and heavy oil 150 were the best carbon sources in production of biosurfactant, E24% was82% and 78% respectively and among different organic and inorganic nitrogen sources, the yeast extract was the bes

Image Improvement Using The Combination of Wavelet and Multiwavelet Transform
...Show More Authors

      This paper introduces method of image enhancement using the combination of both wavelet and Multiwavelet transformation. New technique is proposed for image enhancement using one smoothing filter.

    A critically- Sampled Scheme of preprocessing method is used for computing the Multiwavelet.It is the 2nd norm approximation used to speed the procedures needed for such computation.

  An improvement was achieved with the proposed method in comparison with the conventional method. 

The performance of this technique has been done by computer using Visual Baisec.6 package.

Thermal and Mechanical Behaviour of Heat-resistant Clay-silica Composites
...Show More Authors

The ceramic composite with different proportions of clay and silica was prepared with a grain size of 70 μm and the weight percentage was selected for four groups (clayx silica100-x) were x q15, 25, 30 and 50. In this manuscript, for each pressured sample, a sintering procedure was carried out for 3 hours under static air and at various sintering temperatures (1000, 1100, 1200, 1400)°C. After sintering, the density, porosity, water absorption, compression strength and thermal conductivity were measured. The best results were obtained using a mixture of 15% clay and 85% silica which were sintering at 1400°C for three hours under air.

Molecular detection of MSRA Erythromycin-Resistant gene in Staphylococcus spp
...Show More Authors

 Background: The resistance to antimicrobial factors is an increasingly global problem worldwide, especially among nosocomial bacteria. Staphylococci have become one of the common causes of nosocomialinfections. Multi drug-resistant staphylococci pose a growing problem for human health.
ObjectiveThis study was carried out to evaluate the association between the antibiotic susceptibility patterns and the msrA Erythromycin-Resistant gene in staphylococci isolates obtained from various clinical samples of patients.
Methods: A total of 25 staphylococci clinical isolates were collected from the central Health Lab. DNA from each sample was extracted and The gene implicated in resistance to erythromycin (msrA) was amplified using PCR

Comments on Properties of Gas Rich Dwarfs Galaxies in the Range of Radio Frequencies (B-Band)
...Show More Authors

    In this project we analyze data of a large sample of gas rich dwarfs galaxies including; Low Surface Brightness Galaxies (LSBGs), Blue Compact Galaxies (BCGs), and dwarfs Irregulars (dIr). We then study the difference between properties of these galaxies in the range of radio frequencies (B-band).       The data are available in HIPASS catalogue and McGaugh’s Data Page.  We depended also NASA/IPACExtragalactic Databes web site http://ned.ipac.caltech.edu in the data reduction.       We measured the gas evolution (HI mass), gas mass-to-luminosity ratio, and abundance of the elements such as the oxygen abundance for these galaxies. Our results show a
