The effect of 410nm with 100 mW output power and one centimetre spot size (0.128 W/cm2 power density) Diode laser irradiation at different exposure times on the growth of Gram-negative Pseudomonas aeruginosa and Gram-positive Staphylococcus aureus was evaluated. Seventy swap samples were collected from burn and infected wounds of 35 patients admitted to the burn-wound unit in Al-Yarmouk Teaching Hospital in Baghdad during the period from December 2014 to February 2015. These bacteria were isolated and identified depending on their growth on selective media, cultural characteristics, Gram stain morphology and biochemical tests and finally were confirmed by Vitek 2 compact system test .Susceptibility of bacterial isolates to 15antibiotics was tested using the disk diffusion method. Bacterial standard suspension of 108 cell/ml was prepared for P. aeruginosa and S. aureus. Dilutions of 10-6 cell/ml for P. aeruginosa and 10-5 cell/ml for S. aureus were selected. Ten replicates were used for each experimental group. Following irradiation, CFU/ml was calculated, and antibiotic susceptibility test was performed for the most resistant isolate for each bacterial species. From the results, it was found that out of the 70 samples, 17 isolates (24.3%) were P. aeruginosa and 9 isolates (12.9%) were S. aureus. Antibiotic susceptibility test showed that all isolates of P. aeruginosa and S. aureus were multidrug resistant. It was shown that laser irradiation did not affect the susceptibility of P. aeruginosa isolate to all antibiotics tested. However, a slight increase in the susceptibility of S. aureus isolate to Ampicillin/Cloxacillin, Tetracycline and Vancomycin was observed. Laser Irradiation experiments showed that the number of CFU/ml of P. aeruginosa and S. aureus was significantly reduced with increasing exposure times, reaching a100% bacterial mortality at 13 minutes for S. aureus and 19 minutes for P. aeruginosa. In conclusion, the blue laser irradiation seems to have more bactericidal effect on Gram-positive bacteria (S. aureus) than on Gram-negative (P. aeruginosa).
The research focuses on determining the role of customer relationship management in improving financial performance by surveying the opinions of a number of employees of a number of Iraqi private banks. The customer has become the focus of attention and the most important factors of success and profitability and competition. Therefore, decisions related to the customer are important decisions that support the process of making, And follow-up of administrative decisions, including financial decisions aimed at improving the financial performance of banks and distinguish them from competitors. Thus, the techniques used in customer relations management programs to collect, analyze and use data and information have beco

A laboratory experiment has been carried out in the College of Science-University of Salahaddin to study the effect of different levels (0,5,10 and 15%) and sizes(250 and 1000µm) of walnut seeds residues and (160mg.kg-1) phosphorus fertilization on the concentration of phosphorus availability and alkaline phosphatase activity in calcareous soil during 15 and 30 days period of incubation, the experimental design in factorial complet randomize design (C.R.D) with three replications. The results indicated that the application of different levels of walnut seed residues decreases the concentration of phosphorus availability and alkaline phosphatase activity, however the results revealed that combination between levels and sizes o

Structural, optical, and electrical properties of thin films of CdS : Zn prepared by the solution – growth technique are reported as a function of zinc concentration. CdS are window layers influencing the photovoltaic response of CIS solar cells. The zinc doping concentration was varied from 0.05 to 0.5 wt %, zinc doping apparently increase the band gap and lowers the resistivity. All beneficial optical properties of chemically deposited CdS thin films for application as window material in heterojunction optoelectronic devices are retained. Heat treatment in air at 400 °C for 1h modify crystalline structure, optical, and electrical properties of solution growth deposited CdS : Zn films.

By driven the moment estimator of ARMA (1, 1) and by using the simulation some important notice are founded, From the more notice conclusions that the relation between the sign and moment estimator for ARMA (1, 1) model that is: when the sign is positive means the root gives invertible model and when the sign is negative means the root gives invertible model. An alternative method has been suggested for ARMA (0, 1) model can be suitable when
This study uses the performance of the discretionary estimation models by using a sample of listed companies in the Netherlands and Germany. The actual accounting framework provides a wide opportunity for managers to influence data in financial reporting. The corporate reporting strategy, the way managers use their discretionary accounting, has a significant effect on the company's financial reporting. The authors contribute to the literature through enhancement to these models to accomplish better effects of identifying earnings management as well as to present evidence that is particular to the Dutch and German setting.
For this, we followed the methodology of Dechow, Sloan, and Sweeney (1995) and Chan
