background: quality of life has been used as an important tool to understand illnesses impact in recent decades. idiopathic thrombocytopenic purpura is a chronic disease which affects the individuals’ quality of life. the present study was conducted to compare the quality of life among idiopathic thrombocytopenic purpura patients’ with healthy people. patients and methods: this was a descriptiv...

abstract – aluminium 7075- t651 alloys are widely used in the production of light weight structures requiring a high strength to weight ratio and high corrosion resistance. the effect of processing parameters on fatigue life of 7075- t651 aluminium joints produced by friction stir welding was investigated in the present study. welding samples were made by employing rotating tool speed of 770, 9...

In this research, the effects of the rotational speed, feed rate, tool material and lubricants on the tool life and the hole quality are studied in the frictional drilling of the titanium sheets. The friction drilling tests are performed on a CNC milling machine. Furthermore, 5 specimens are selected and their metallurgical structures are studied. The results show thatamong the input parameters...
