This research aims to identify the effectiveness of modern media technologies represented by satellite TV in the development of good citizenship values when students. To achieve this purpose were selected a sample of 44 students in the Department of Electrical technologies in Technical Institute in Nasiriyah in southern Technical University during the school year (2015-2016).
Was determined the general objectives of the use of modern media techniques represented satellite TV is to promote the values of good citizenship among the sample of students in order to make them good citizens in the community could contribute to the development and upgrading it. And put the general plan of research. Promising researchers measure of good citizenship for undergraduates values of a component of a number of paragraphs in which we can check the availability of good citizenship values among a sample of students and research that could contribute to the development of society. And extracted psychometric characteristics such as sincerity and consistency of this scale using statistical methods known to be ready for the application of the research sample.
After that, one of the researchers compiled a number of guided by a number of national satellite channels, temperate and containing topics aimed at different tips that urges students and youth citizenship and good values and good morals, and the development of the national spirit and attention to Islamic by the principles Alhanifp good social traditions, all in TV programs trying to create good citizens committed able to contribute to the reform of society and its development. It was this television programs put on compact discs (CD) for the purpose of distribution to the research sample to see them and take advantage of the positive contents.
And it began to apply the researcher conducting the tribal scale application of good citizenship values when the students to sample and analyzed its results. Then hold hearings to the research sample to show aimed at programs that have been compiled from satellite TV channels them two hours a week for five consecutive weeks. It was then holding the post applied for a measure of good citizenship values when the students to sample and analyzed the results using a number of appropriate statistical methods.
And it reached the search results to get the research sample is statistically significant and positive growth for the values of good citizenship among students after briefed on the programs that have been compiled from satellite TV than it was before knowing. The researchers concluded that the presence of a positive impact of modern media technologies in the development of good citizenship values when students could benefit from the upgrading of society and its development process. The researchers recommended that the importance of benefiting from targeted programs offered by satellite TV channels for these purposes beneficial among students and young people and proposed conducting complementary research for this research in this area for the development of good citizenship values when students in such circumstances through which our dear country.
Many researchers consider Homogeneous Charge Compression Ignition (HCCI) engine mode as a promising alternative to combustion in Spark Ignition and Compression Ignition Engines. The HCCI engine runs on lean mixtures of fuel and air, and the combustion is produced from the fuel autoignition instead of ignited by a spark. This combustion mode was investigated in this paper. A variable compression ratio, spark ignition engine type TD110 was used in the experiments. The tested fuel was Iraqi conventional gasoline (ON=82).
The results showed that HCCI engine can run in very lean equivalence ratios. The brake specific fuel consumption was reduced about 28% compared with a spark ignition engine. The experimental tests showed that the em

In Aqueous Two-Phase Systems, many factors influence the Partition coefficient, K, (which is the ratio of protein concentration in the top phase to that in the bottom phase) and the Recovery percentage (Rec%). In this research, two systems of ATPS were used: first, polyethylene glycol (PEG) 4000/Sodium citrate (SC), and the second, PEG8000/ Sodium phosphate (SPH), for the extraction of Bovine Serum Albumin (BSA). The behavior of Rec% and K of pure (BSA) in ATPS has been investigated throughout the study by the effects of five parameters: temperature, concentration of polyethylene glycol (P
... Show MoreThis study conducted an analytical investigation on the behavior of concrete beams with openings reinforced by glass-fiber-reinforced polymer (GFRP) bars. In this study, five proposed beams reinforced by GFRP bars as flexural and shear reinforcement with openings were numerically examined. The variables were the opening orientation (vertical and horizontal) and the number of openings. These openings were located within the flexural zone of the proposed beams. The result shows that the vertical openings had a significant effect over the horizontal openings on reducing the ultimate load and increasing the mid-span deflection compared with the control beam. Moreover, the results showed t
Background: A great dental and biomedical interest had been paid to silver nanoparticles because of their antimicrobial activity. Objective: To evaluate the antimicrobial and cytotoxic activity of a newly developed Nano-silver fluoride that was synthesized from moringa oleifera leaf extract against S. mutants. Material and method: The green synthesis method was used to prepare Nano-silver fluoride from moringa oleifera leaf extract. The minimum inhibitory concentration and the minimum bactericidal concentration were evaluated using brain heart infusion plates, while the cytotoxicity was evaluated by the hemolytic activity. Results: Nano-silver fluoride had a bactericidal and bacteriostatic effect (MIC was 60 ppm a

A series of new 4(3H)-quinazolinone derivatives (S1-S4) were synthesized and characterized by FTIR,1HNMR and 13CNMR .Their cytotoxic activity against a set of human cancer cell lines MCF-7 (breast) and A549 (lung) was evaluated using MTT assay. To detect their selectivity toward cancer cells, the compounds were also tested against epithelial cells derived from normal human fibroblast (NHF). Methotrexate (MTX) was used as a reference for comparison . All the tested compounds exhibited toxicity against the normal cells lower than cancer cells. All the tested compounds displayed higher cytotoxicity against lung cancer cell line (A549) than MTX with the most
