Effect of Annealing temperature on the Structural, Optical and Sensitivity Properties of Nanostructure SnO2 Films to CO2 and NH3 Gas
...Show More Authors

In this research, we studied the structural properties of SnO2 films nanostructure which prepared by chemical spray pyrolysis method at room temperature on the rules of glass heated (400oC) with rate of spraying (2.5 ml/ min). The effect of annealing temperaturs (450,500,550,600 and 650oC) for two hours on those properties has been indicated. The results of x-ray diffraction showed that all of the prepared films were polycrystalline with tetragonal type and orientation was (110) for all models before and after annealing, and the annealing led to an increase in the grain size. The full width at half maximum (FWHM) values of the (110) peaks of the films decreased from 1.492o to 1.064o with increasing annealing temperature .The surface morphology of the (SnO2) nanostructure films have been studied using atomic force microscopy (AFM) which indicated that the grown films showed good crystalline and homogeneous surface . The Root Mean Square (RMS) values and surface roughness of the films decreased with increasing the annealing temperature. The optical properties of the films were studied by (UV-VIS-NIR) spectrophotometer in the wavelength range (300-1100 nm). The optical transmission results showed high transmittance (87%) at annealing a temperature (650oC). The energy gap for direct transmission was calculated before and after annealing. From the gas sensing measurements of SnO2 films for (CO2 , NH3), showed a good sensitivity at 50oC. It was found the that best sensitivity of SnO2 films at annealing temperature 650oC were (100%) for NH3 (98.78%).

The derivation of “Allah” names was denied due to a creed thoughts, because saying that “Allah” names is derived will not describe the eternal essence of “Allah”, and if it were derived this will make “Allah” is a Compound from his essence and Attributes.
The Al-Zaher people had recant the derivation of the agent nouns by preventing the derivation of “Allah” names because it will make “Allah” is a Compound from his essence and Attributes.

The European Union and the Extremist Right Phenomenon: Brexit as a Model
...Show More Authors

The European Unit has never been affected by a serious phenomena as the phenomena of the advancing of the far right parties. Though these parties vary in their impact in their original countries, they agree on one important issue which is the deconstruction of the European unit and limiting its supernational powers. These increasing popular parties aim at more national independence in decision making away from the decisions taken by Brussels. Moreover, they criticize the financial and administrative corruption accompanied many of the rescuing procedures directed for example towards countries like Greece and Spain during the international economic crisis. This failure nourishes many of the negative feelings against the European unit which

The Eloquence of the Sound in the Production of Mental Image in the Feature Film
...Show More Authors

The ideas and information obtained by the viewer in the cinema have always been the source of the visual image, but that doesn’t negate the fact that the mental image can produce a lot of the information and ideas in the cinematic art and the most important means to achieve this mental image in the film is the eloquent cinematic sound. This research is conducted to show this important and effective contribution of the sound in the production of the mental image. Hence the importance of this research is in that it addresses an important issue which is the eloquent performance of the sound and its role in the production of the mental image inside the space of the feature film. This research concerns those working the field of cinema and

...Show More Authors

Abstract

The current research aims to develop a guidance program suitable for high school students and apply it to them in order to ensure the reduction of addiction to the use of different means of communication. The researchers used the scale of addiction to the means of communication (SAS) to measure the level of addiction as well as to identify the impact of the proposed guidance program in reducing the degree of addiction to communication. It was applied to a sample of (20) female students divided equally into two groups: an experimental group of (10) female students and a control group of (10) female students from the secondary level in a school under the department of education in the education of the alma
