The importance of the research lies in preparing an experimental curriculum according to a scientific method that will contribute to the development of the special strength(endurance the strength of arms) in order to contribute to the attempt to develop the basic skills of the national team players with the goal ball for the blind As for the research problem, it lies in the weakness of the strength endurance of the national team players with the goal ball for the blind, as the research problem is clearly evident in the last minutes of the match, as well as the former studies in the field of goal ball game for the blind at the country level The research aims to prepare special exercises for endurance of strength as well as to identify the effect of special exercises on the players of the national team with a goal ball for the blind and to suggest the best ways for the development of this category The researchers hypothesized that there are statistically significant differences between the pre and post test of the subjects of the research sample As for the research methodology, the two researchers used the descriptive method in the survey method. The research community was identified with the national team players for the goal ball for the blind, whose number is (6) players As for the research procedure, it consists in preparing special exercises that carry strength for the arms The two researchers reached a set of conclusions, the most important of which was the interest in using such training methods or special exercises for strength on the teams of the Goal Ball game for the blind
Zubair Formation is one of the richest petroleum systems in Southern Iraq. This formation is composed mainly of sandstones interbedded with shale sequences, with minor streaks of limestone and siltstone. Borehole collapse is one of the most critical challenges that continuously appear in drilling and production operations. Problems associated with borehole collapse, such as tight hole while tripping, stuck pipe and logging tools, hole enlargement, poor log quality, and poor primary cement jobs, are the cause of the majority of the nonproductive time (NPT) in the Zubair reservoir developments. Several studies released models predicting the onset of borehole collapse and the amount of enlargement of the wellbore cross-section. However, assump
