Study the Electronic and Spectroscopic Characteristics of p-n Heterojunction Hybrid (Sn10O16/C24O6) via Density Functional Theory (DFT)
...Show More Authors

The electronic characteristics, including the density of state and bond length, in addition to the spectroscopic properties such as IR spectrum and Raman scattering, as a function of the frequency of Sn10O16, C24O6, and hybrid junction (Sn10O16/C24O6) were studied. The methodology uses DFT for all electron levels with the hybrid function B3-LYP (Becke level, 3-parameters, Lee–Yang-Parr), with 6-311G (p,d)  basis set, and Stuttgart/Dresden (SDD) basis set, using Gaussian 09 theoretical calculations. The geometrical structures were calculated by Gaussian view 05 as a supplementary program. The band gap was calculated and compared to the measured values. The density of state of the hybrid junction (Sn10O16/C24O6) increased because of the increased number of degeneracy states. Theoretical values of bonds for C=C, C=O, and Sn-O are equal to 1.33, 1.20 and 2.27 Å respectively, these bonds values are in good agreement with experimental values of bond length of 1.34 for the C=C bond, 1.23 for the C=O bond, and 2.3 for the Sn-O bond. . The spectroscopic properties, such as IR spectra have shown a peak which is comparable to longitudinal modes of GO and tin dioxide SnO2 at  (1582 and 690) cm-1, respectively.

The effectiveness of a rehabilitation program with aqueous media on the egree of pain and balance for those suffering from sacroiliitis in football players
...Show More Authors

Abstract in English  The aim of this study is to identify the effectiveness of rehabilitation exercises in conjunction with aquatic therapy for those suffering from sacroiliitis in football players. The researcher used the experimental approach, using the experimental design (pre-measurement, post-measurement). Similar to the objectives and procedures of the research, the researcher assumed the following: the existence of significant differences. Statistics between pre- and post-measurements in variables in favor of post-measurement for the following variables (degree of pain and level of balance). The experimental approach was used with a pre- and post-measurement design on one group of football players with sacroiliitis, nu

Evaluation of the anterior loop of the mental nerve incidence and extension in different age groups in Sulaimania city using digital panoramic imaging system
...Show More Authors

Background: The anterior loop of mental nerve is commonly described as that part of the neurovascular bundle that transverses anterior and inferior to the mental foramen only to loop back to exit the mental foramen. The aim of the study is to evaluate the incidence and extension of anterior loop of mental nerve by using digital panoramic imaging system to avoid nerve damage during different surgical procedures in dentistry. Materials and Method: Panoramic image was taken for all 400 patients and stored in the computer. Then Horizontal and Vertical for the anterior loop extension when exist was measured and recorded in a special case sheet prepared for each subject. Results: Results indicated that out of 400 patients there were only 25 pat

The Role of Public Relations in Promoting Tourism from the Public Relations officers’ Point of View in Palestinian Travel and Tourism Companies in Gaza
...Show More Authors

The aim of the research is to identify the role of public relations in promoting tourism by the Palestinian tourism and travel companies in Gaza from the public relations officer’s point of view in those companies.
The researcher used the descriptive analytical method as the most appropriate for such studies and implemented the questionnaire as a tool to obtain the required data from the respondents.
The Researcher reached several conclusions:
1- There is a low percentage of women working in the field of public relations in Palestinian tourism establishments in the Gaza Strip, where the percentage did not exceed 5%.
2- The interpersonal communication counted as one of the elements of integra

Abstract<sec><title>Objectives

To investigate the antiplaque and antigingivitis efficacy in addition to evaluating side effects and subjects’ perceptions of three commercially available mouthwashes.

Methods

This study was a double‐blind, parallel, and short‐term trial. A total of 75 dental students with biofilm‐induced gingivitis were included in the final analysis of the current study. Clinical parameters (plaque index and bleeding on probing) and the staining effect were measured at baseline and after 7 days. In addition, a VAS‐based assessment questionnaire was completed by the participants.
