In this research, the stopping power and range of protons in biological human soft and hard tissues (blood, brain, skeleton-cortical bone, and skin) of both child and adult are calculated at the energies ranging from 1MeV to 350 MeV. The data is collected from ICRU Report 46 and calculated the stopping power employing the Bethe formula. Moreover, the simple integration (continuous slowing down approximation) method is employed for calculating protons range at the target. Then, the stopping power and range of protons value in human tissues have been compared with the program called SRIM. Moreover, the results of the stopping power vs energy and the range vs energy have been presented graphically. Proper agreement is found between the gained and the SRIM results and varies almost linearly with energy up to 250 MeV.
Abstract
Due to increased interest on organizations and the human element, organizational and environmental aspects of the organization Has been analyzed, and behavioral aspects of the members and what is the impact of each on the other, To give the recipe interaction between the organization and its environment, in order to bring about change in behavior appeared the concept of organizational health as a concept in a modern organizations, Either the organization to be stimulating good, healthy, and then called healthy organization Or that the situation be frustrating it is not good and unhealthy, so the cause of tension and anxiety, unhealthy organization is here The research aim to determine the existence of organizatio

The most common threat that human beings might pass through is the trauma which is commonly bound with wars. The greater trauma that human beings might have is the threatening sudden facing or death facing. Consequently there would be disorder especially War disorder. This Phenomenon is clearly observed in Iraqi society as Iraq has been passing through continuous wars and disasters namely during and after the American Invasion. These events might lead to changes in Peoples behavior and to Social Violence. Thus, the Study aims at:

... Show MoreThis study aims at exploring primary school pupils' understanding of
the meaning of lexical items and language structures. The study sample
consists of 40 second year primary school pupils. The results reveal that
the percentage of the pupils'. Understanding of the meaning of lexical items
is 72.7% that of language structures "verbal and nominal clauses" is 82.3%
and that of language structures "negative, interrogative, vocative, reference
and prepositions" is 86.5%. The study also reveals that there is no
statistically significant difference between the achievement of male pupils
and that of females.
What we observe from the weakness of the students in some of different subjects may be due to that students are learning these traditional methods and competing to acquire the mark, and attain their teachers' interest ,then their only aim becomes the academicsuccess, and this is whatcontradicts the modern educational philosophy.
Education needs to be providing it with new ideas and methodologies toprepare an emerging demonstrated scientific reason to distance them from the tradition and indoctrination that do not create generations able to address theexpected problems.
