International Public Relations (An Analytical Study of the Speeches of US President Barack Obama Addressed to the Arab Countries in Crisis)
...Show More Authors

In the midst of political, cultural and economic fast developments accelerated, the world witnessed, with the accompanied big communication revolutions, many shapes of powers. Those developments were followed by changes in relations of international level.

The most prominent among those developments was the international public relations which became equal to official international relations. Moreover, the international public relations became a complementary element dur to the growth of public opinion and its affection on political regime. Such growth of public opinion pushed the politicians to address it; and try to gain its support.

The US was the first realized the importance of international public relations. The Presidents of the United States keep directing their speeches to the world to improve the image of the united states and presented it as a political, economic, and cultural power with a unique, moral and human feature.

Because, those Presidents have tried to develop the united states external relations; and to improve US international treatments depending on the international public support. A support like that can be gained by the international relations styles and their arts.

This research aims to analyze the speeches of Barak Obama directed to the Arabic countries in crisis, (Palestine, Iraq, Tunisia, Egypt, Syria, Sudan, Yemen, Bahrain) to know the contents of those speeches.

It was realized from the result of the study that the American President Barak Obama is well realized of the negative image of his country at Arabic and Islamic people.

Therefore, he tried, in many places of his speeches, to give moral and humanist excuses of existence of US in the Arab countries; and to ensure that the United States is a permanent friend to people in crisis and that the united states are eager for their interests mentioning  that US had a crucial role in liberating people from tyrant regimes.

Obama, nevertheless, tried to give detailed descriptions of the Arabic environment under crisis before and after changes stating the differences between them.

Obama praised the Islamic World; and focused on commonalities with the Islamic societies. But he clearly biased to Israel when he had dealt with the Palestinian dilemma, although his speeches contained a lot of humane values that confirm that the US supports justice and human right.

THE EFFECT OF A PROTECTIVE BARRIER ON THE SHEAR BOND STRENGTH OF DIFFERENT ORTHODONTIC BRACKETS
...Show More Authors

Background and objectives: This study aimed at testing the effect of plastic sleeve or barrier, used to cover the guide of the light cure unit to prevent cross-infection, on the shear bond strength and site of bond failure of stainless steel and ceramic orthodontic brackets. Materials and methods: Forty orthodontic brackets; twenty stainless steel and twenty ceramic brackets bonded to forty extracted human maxillary first premolars using light cure adhesive cured with and without the use of a protective plastic barrier on the guide. Comparing the effect of this barrier on the shear bond strength and adhesive remnant index was performed using an independent t-test and Chi-square test. Results: The protective barrier had decreased the shear b

The effect of volume fraction on the fatigue strength of unsaturated polyester / glass fiber composite
...Show More Authors

 In this work polymeric composites were done from unsaturated polyester as a matrix reinforced with glass fiber type (E-glass) with two different volume fraction 20% & 40%. Fatigue tests showed that the number of fatigue cycles to failure limit for samples reinforced with uniform (woven Roving 0-90°) E-glass fiber and random (continuous fibers) with volume fraction 40% more than that for the same samples with volume fraction 20%. Also the fatigue results showed that the uniform samples failed with fatigue cycles more than that of random.

Investigating the effect of nanomaterials on the Marshall properties and durability of warm mix asphalt
...Show More Authors

This research aims to investigate the effect of four types of nanomaterial on the Marshall properties and durability of warm mix asphalt (WMA). These types are; nano silica(NS), nano carbonate calcium (NCC), nano clay(NC), and nanoplatelets (NP). For each type of Nanomaterial, three contents are tried as following; NS(1%, 3%, and 5%), NCC(2%, 4%, and 6%), NC(3%, 5%, and 7%), and NP (2%, 4%, and 6%) by weight of asphalt cement. Following Marhsall mix design method, the optimum asphalt cement content is determined, thereafter the optimum dosage for each nanomaterial is obtained based on the highest Marshall stability value. The durability of the control mix (no nanomaterial) and modified mixtures have been compared based on moisture damage, r

Impact of using Double Layers Perforated Liners on the Acoustic Treatments of the Combustor Systems
...Show More Authors

The response of the combustor’s liner to the air-flow that passes through it is the key reason for the combustion chambers noise, hence the instabilities of those chambers that decreases the mechanical efficiency of such sections, by increased its mechanical vibrations, which increases the failure rate created during originating of the cracks spreading by the shakes producing by the series of high-level frequencies. Accordingly, any work debating the impact of the context of liners in the combustion chamber can provide grasping for the combustion noise generated by the undesirable vibrations, and benefits the industrial firms to design an ideal production procedure which increases the lifespan of the combustor. The goal of this work is

The role of antibiotics and probiotics supplements on the stability of gut flora bacteria interactions
...Show More Authors

Dyspepsia is a significant public health issue that affects the entire world population. In this work, we formulate and analyze a deterministic model for the population dynamics of Gut bacteria in the presence of antibiotics and Probiotic supplements. All the possible equilibria and their local stability are obtained. The global stability around the positive equilibrium point is established. Numerical simulations back up our analytical findings and show the temporal dynamics of gut microorganisms.

The Effect of Increasing Carbon Concentration Increasing on the Mechanical Properties of TiCx Thin Films
...Show More Authors

Carbides or nitrides thin films present materials with good mechanical properties for industrial applications as they can be coatings at low temperatures serve temperature sensitive surfaces. In this work the effect of the C percentage on the mechanical properties represented by the Young modulus (E) of combinatorial magnetron sputtered TiCx (34%x˂65%) has been studied. The structure of the produced films is TiC independent on the C concentration. The mechanical properties are increased with increasing the C concentration up to 50%, and then decreasing with further C % increasing. These results can be explained by considering the resultant residual stresses.

Influences of the Twisted Strips Insertion on the Performance of Flat Plate Water Solar Collector
...Show More Authors

Abstract

    In order to enhance the efficiency of flat plate solar water collectors without changing in its original shape and with low additional cost, twisted strips are inserted inside its riser pipes. Three flat plate collectors are used for test. Family of twisted strips are inserted inside each collector risers with different twisted ratios (TR=3,4,5). The collectors are connected in parallel mode (Z-Configuration) and are exposed to the same conditions (solar radiation and ambient temperature) .The experimental results show that, the highest heat transfer rate occurs at twisted ratio (3) .Consequently, for the same twisted ratio the daily efficiencies for the solar collector at d
