In this study, Al2O3 thin films were prepared by dc reactive sputtering technique using different gas mixtures of argon and oxygen gases (90:10, 70:30, 50:50, 30:70, and 10:90). These films were characterized to introduce their surface morphology and elemental composition as functions of the oxygen content in the gas mixture. The gas mixing ratio plays a crucial role in controlling the nanoscale morphology of the prepared thin films. The [Al]/[O] ratio varies non-linearly with the Ar:O2​ mixing ratio. Increasing the oxygen content leads to a progressive decrease in surface roughness, resulting in smoother and more uniform films with finer granular features. These results presented herein are useful to optimize the sputtering process to ac

This research is an attempt 0f discovering an advice and mention kinds of politics  with administration sides through the Umayyad  era in the way of showing it which had directed to successors and princes in the state , whereas this subject did not take the chance , as historian research which dealt with this advice through the continuous period after the early Islam and Umayyad era

The Bajilian had their important part in the first civilian war between
Muslims. Whether they were against the Umayyad caliphate or with it, who
were small in number, but they had their important part in that actions.
The Bajilian who were against the umayyad caliphate had an important
role in the fall of Umayyad monarchy.
The tribe connections between the bajilians were stronger than their
political differences, which had influnces in that time. The bajilians who were
in muawiya palace were a good diffencer for the bajilian who were in the side
of the caliph ali. They managed to be their medicater in the muawiya palace. 

There were big efforts giving by others in order to decrease the bajilian

     The manuscript depictions of the Ilkhanate era in Iran reflect the cultural and artistic dialogue approach that prevailed in that period ,when a movement of openness to literature from different sources occurred, which led to the emergence of new features
