Purpose: The present study was done to specify the impacts of a protocol called “living high, training low and high (LHTLH)”on serum ET-1 and EPO levels as well as the 3000-m performance of endurance runners in Iran’s national team. Method: eight male runners (aged24.4±3.1, height of 180.5±4.2, weight of66.7±3.4 and BMI of20.1±5.0kg/m2) who cooperated voluntarily with regard to middle distance and marathon running (R2M system training) at high and low altitudes. All case studies did 3000-m test and blood samples were taken at a time period of 24-hours before and after the test. The intended tasks consisted of continuous, interval, aerobic and resistance exercises. The runners were to take part in 16 training sessions each week. It should be noted that the training lasted for 11 weeks according to (LHTLH) protocol. Variance with repeated measures (P≤0.05) was utilized as the method to analyze the collected data. Results: It was shown that 3000-m time underwent significant decrease with regard to the time of impact both before and after the training. However, there were not significant changes in EPO (P≥0.05). On the contrary the amount of ET-1 demonstrated significant increase (P≤0.05). Conclusions: The results indicated that 3000-m time at lower altitudes will decrease on account of certain training programs. The reason is not directly related to the level of EPO. It is through hematological and metabolic changes as well as increase of ET-1 levels that performance under hypoxic and normoxic states happens to improve in the real sense.

This study is reassessing the geopolitical consideration of the British government in the Sixth Days of the Arab-Israeli War,1967. Based on declassified documents from the British’s archive, this paper will analyze the geopolitical factor which shaped London’s reaction towards the conflict. Middle East geopolitical position was very strategic to the British interests in the region. Hence, the focus of this paper is to re-examine the consequence of the war toward Britain’s attitude in preserving her strategic military position and economic calculation in the Middle East between 1960s to early 1970s. These including the paramountcy of the British military bases in the region, arm trade commercial activities and a disruption of the oil flow from the region to the West. From historical perspective and analysis, this paper argued that the threats from the Soviet and Arab nationalist movements during the conflict had significantly influenced the British government’s reaction towards the war. Although London did not involve directly in the conflict like in the 1956’s Suez Crisis, yet British’s response was still crucial since Britain was the prime architect in drafting and tabling the United Nation Resolution 242 after the war. Indeed, this research inclines to believe that the British equilibrium attitude as proclaimed during the conflict was not purely based on a principle of a just and lasting peace but it was very much relying upon geopolitical consideration of safeguarding British major strategic interests in the region.   .

In order for a classical foreign-language drama to be performed in the target country, a suitable translation is required so that the audiences understand the physical version of the play. This research indicates that the translation of a drama on pages differs from the translation of that drama on stage. This study was conducted to examine the differences between the translation on page and stage of Macbeth, the result of which can help improve the quality of the translation on the stage of a play. In this study, the researcher compares the translated text of Macbeth's play with its translation on stage. This comparison is based on Kowzans' (1968) framework that introduced 13 theatrical systems with 5 subcategories namely; Spoken Text, Body Expression, Stage Appearance, External Appearance of Actor(s), and Inarticulate Sound. The frequency of each of the categories was calculated and it was found that the spoken text category has the largest number of differences between the translation on pages and stage by 42% percent since the spoken text deals with the translated text more than other categories. The results of this study will be beneficial for strengthening the actor's relationship with the text, and translators' quality of translation.
