The aim of this work is to perform an experimental study for the effect of forced vertical vibrations on free convection heat transfer coefficient, from flat plate made of Aluminum with dimension (300 Length*100 Width*3 thickness mm).It's heated under a constant heat flux of (250-1500 W/m2 ) upward. The flat plate was located horizontally or inclined in multiple angles at rang of (0o , 30o , 45o 60o ، 90o ). The experimental study is carried out at a range of frequency (2-16 Hz) ، the amplitude at the range of (1.63-7.16 mm), and the Rayleigh number at the rang (138.991< Ra <487.275).
The results of this study show that, the relation between the heat transfer coefficient and the amplitude of vibration is incrementally for incl

The graphic field invests the visual space then shows the shape by all means of expression that have a certain meaning. The research is interested in studying the iconic form in the modern graphic design through investing names and flags and the extent of their action in the social life and invest them from one to another looked at from viewpoint of trading and consumption and investing their wide popularity. The study problem is manifested in the following question:
1- Does the iconic form help in ad circulation?
The importance of the research lies in the following:
1- Reading the visual iconic form through deciphering its current symbols. The form combines a concept and a case or a form and meaning.

The theoretical fra

الملخص: منذ نهاية الحرب العالمية الثانية ولغاية الآن عجزت روسيا واليابان عن إبرام معاهدة تنهي رسمياً الأعمال العدائية بين البلدين، وتنهي تنازعهما حول جزر المحيط الهادئ المعروفة يابانيا بالأقاليم الشمالية، وروسياً بجزر الكوريل الجنوبية. ومع الغزو الروسي لأوكرانيا زادت علاقات البلدين تدهورا، وتوقفت مساعي تطويرها التي بدأها رئيس الوزراء الياباني الراحل شينزو آبي ، ما يثير التساؤل حول مستقبل العلاقة بي

The Arab economy suffers from many structural imbalances problems which are getting complicated by the appearance of the world economic variables.

This change held risky challenges for the Arab economies in the light of unsuitable regional and international conditions. Since that it has been very essential  for the Arab experts, especially those related to economy and politics, to face those new challenges or, at least, adapt with them believing that they can have both positive and negative impacts on the Arab economy.

This study has acquired its importance in the light of the critical levels the Arab economy reached out of the world economic variables, resulting in long-term

        The searchers opinions are variant in determining the extent of impacting political risk in the host country on foreign direct investment decision. (Aharoni,1966) found, in his questionary study for group of foreign companies operating in India, that a political stability is one of the two most important factors, besides the market size, in the attraction of foreign investment, and its availability means that whether this  specific country  is good for foreign investment. On the other side, (Green and Benntt, 1972) are present a variant opinion to Aharonis opinion. They are reach to result state that a political instability do not impact on the general distribution of foreign i
